I. Introduction
In today’s fast-developing apparel industry, the automatic garment multi-layer cutting machine, with its advanced technology and high efficiency performance, has become a key equipment for enterprises to improve production efficiency and product quality. It can accurately cut all kinds of fabrics according to pre-designed paper samples, which greatly reduces the error and labour intensity of manual cutting. However, the operation of automatic garment multi-layer cutting machine is not simply pressing the button, it involves a number of links and complex technical parameters. If the operator does not understand the relevant precautions, it may not only affect the quality and efficiency of cutting, but also lead to equipment damage or even endanger the safety of the operator. Therefore, it is of great practical significance to understand the precautions in the operation process of automatic garment multi-layer cutting machine.
II, the operator requirements
2.1 The need for professional training
Automatic garment multi-layer cutting machine is a high-tech equipment, its internal structure and working principle is more complex. Operators must be professionally trained to operate the equipment correctly. Professional training allows the operator to understand the performance of the multi-layer cutting machine, operating methods and safety standards. For example, through training, operators can know how to properly start and shut down the equipment and how to perform routine equipment inspection and maintenance. Personnel without professional training may cause equipment failure or even safety accidents due to improper operation. According to statistics, most multi-layer cutting machine equipment failures and safety accidents are caused by improper operation by operators. Therefore, the enterprise must ensure that all operators have received professional training, and obtain the corresponding operating qualification certificate.
2.2 Mastery of professional knowledge
The professional knowledge that operators need to master includes the basic principles of multi-layer cutting machine, mechanical structure, electrical system and other aspects. Understanding the basic principles of multi-layer cutting machine can help operators better understand the working process of the equipment, so as to make the right decisions in the operation process. For example, when the problem of reduced cutting accuracy occurs during the cutting process, the operator can analyse the possible causes, such as the wear of the cutting knife and unreasonable parameter settings, according to the working principle of the multi-layer cutting machine. For the mechanical structure of the multi-layer cutting machine, the operator should be familiar with the name, function and location of each component so that he can quickly locate the problem when the equipment fails. At the same time, the operator also needs to understand the basic knowledge of the electrical system to avoid safety hazards caused by improper electrical operation.
2.3 Cultivation of Safety Awareness
In the operation process of multi-layer cutting machine, safety is crucial. Operators must have a strong sense of safety and strictly comply with safety regulations. The cultivation of safety awareness includes the learning and understanding of safety regulations, as well as conscious compliance in actual operation. For example, operators should know that they must wear appropriate safety protection equipment, such as gloves and goggles, when operating the multi-layer cutting machine. At the same time, they should always pay attention to the safety of the surrounding environment and avoid unnecessary operations during the operation of the equipment. Enterprises can improve the safety awareness of operators and emergency response capabilities through regular safety training and safety drills.
III. Preparation before use
3.1 Countertop Cleaning
A clean and tidy countertop of the multilayer cutting machine is an important prerequisite for ensuring the quality of cutting. Before use, the operator should carefully clean the debris, dust and fabric residue on the table surface. If there is debris on the table, it may affect the flat placement of the fabric, resulting in deviations when cutting. For example, a small piece of fabric residue may cause the fabric to move slightly during the cutting process, thus affecting the accuracy of the cut. In addition, a clean countertop extends the life of the cutter, as debris may scratch the cutter and cause it to become dull. Operators can use special cleaning tools, such as hoovers and rags, to clean the table surface.
3.2 Cutting Knife Inspection
The cutting knife is a key component of the multi-layer cutting machine, and its sharpness and solidity directly affect the quality and efficiency of cutting. Before use, the operator should check whether the cutter is sharp. This can be judged by observing whether the blade of the cutter is worn or chipped. If the cutting knife is not sharp, the cutting will be cut unevenly, burrs and other problems. At the same time, check that the knife is installed in the correct position to ensure that it follows the preset cutting path accurately. The stability of the cutter is also very important. If the cutter is not firmly installed, it may wobble during the cutting process, resulting in a loss of cutting accuracy. The operator can use professional tools to check and adjust the cutting knife.
3.3 Inspection of Other Components
Besides the table and the cutting knife, the operator also needs to inspect other components of the multilayer cutting machine. For example, check whether the transmission system is functioning properly and whether the belt is loose or worn. The normal operation of the transmission system is the basis for ensuring the stable work of the multi-layer cutting machine, and if the transmission system fails, it may lead to unstable cutting speed, cutting position deviation and other problems. At the same time, it is necessary to check whether the control system is normal and whether the functions can be realised normally. The control system is the brain of the multi-layer cutting machine, which controls the operating parameters and cutting action of the multi-layer cutting machine. If the control system fails, it may cause the whole multi-layer cutting machine can not work normally. In addition, it is also necessary to check whether the dust-absorbing system is normal, and the dust-absorbing system can timely clean up the fabric debris generated in the cutting process and keep the working environment clean.
IV. Parameter Settings
4.1 Cutting Thickness Setting
Cutting thickness is set according to the characteristics of the clothes and fabrics to be cut. Different fabrics have different thicknesses and hardnesses, so it is necessary to set different cutting thickness parameters. If the cutting thickness is set too high, the cutter may not be able to cut the fabric completely, resulting in incomplete cutting. On the contrary, if the cutting thickness is set too small, it may increase the number of cutting times and reduce the production efficiency. The operator needs to set the cutting thickness through the control panel of the multi-layer cutting machine according to the actual situation of the fabric. In the setting process, the material of the fabric, the number of layers and other factors should be referred to ensure the accuracy of the cutting thickness.
4.2 Cutting speed setting
Cutting speed is also an important parameter, which directly affects the efficiency and quality of cutting. Cutting speed is too fast, which may cause the cutting knife to produce large friction in the cutting process, making the knife heat up, thus affecting the service life of the knife. At the same time, too fast cutting speed may also lead to fabric cutting is not neat, burrs and other problems. Too slow cutting speed will reduce the production efficiency. The operator needs to set the cutting speed reasonably according to the material of the fabric, cutting thickness and other factors. Generally speaking, for thinner, softer fabrics, you can appropriately increase the cutting speed; for thicker, harder fabrics, you need to reduce the cutting speed.
4.3 Multi-layer Cutting Machine Width Setting
Multi-layer cutting machine width setting should be determined according to the size of the clothes to be cut and the paper sample. If the width of the multi-layer cutting machine is set too small, it may not be able to meet the cutting needs; if the width of the multi-layer cutting machine is set too large, it will be a waste of equipment resources. The operator needs to carefully measure the size of the garment and the width of the paper sample, and then make the appropriate settings on the control panel of the multilayer cutting machine. In setting the width of the multi-layer cutting machine, but also consider the width of the fabric, to ensure that the fabric can be placed smoothly on the multi-layer cutting machine to avoid fabric folds or offset.
V. Precautions in the cutting process
5.1 Maintenance of safety distance
In the cutting process, make sure that personnel and other materials and multi-layer cutting machine to maintain a safe distance. Multi-layer cutting machine in the process of operation, the cutting knife rotates at high speed, with a certain degree of danger. If personnel are too close to the multi-layer cutting machine, they may be cut by the cutter. At the same time, other materials such as fabrics, tools, etc. should not be placed near the multi-layer cutting machine, so as not to be caught in the multi-layer cutting machine, affecting the normal operation of the equipment. Companies can set up safety warning signs around the multi-layer cutting machine to remind operators and other personnel of the safety distance. Generally speaking, the safety distance between personnel and the multi-layer cutting machine should be no less than 1 metre.
5.2 Monitoring of the cutting process
Operators should always monitor the cutting process and observe the operating status and cutting effect of the multi-layer cutting machine. Be careful to observe the cutting situation of the cutter, whether there are problems such as poor cutting, burrs on the fabric and so on. If abnormalities are found, stop the machine in time for inspection. At the same time, it is necessary to monitor whether the parameters of the multi-layer cutting machine are normal, such as cutting speed, cutting thickness and so on. If the parameters are abnormal, it may affect the quality and efficiency of cutting. The operator can monitor the running status of the multi-layer cutting machine in real time through the display or monitoring system of the multi-layer cutting machine.
5.3 Handling of unexpected situations
During the cutting process, some unexpected situations may occur, such as fabric jamming and equipment failure. The operator should have the ability to deal with unexpected situations. When the fabric is stuck, stop the machine immediately and take out the stuck fabric carefully to avoid forcibly pulling the fabric resulting in fabric damage or equipment failure. If the equipment malfunctions, operate in accordance with the equipment’s troubleshooting procedures, such as switching off the power supply of the equipment and investigating the cause of the malfunction. When dealing with emergencies, report to the leader or relevant personnel in a timely manner in order to get timely support and help.
VI. Handling after cutting
6.1 Countertop cleaning
After cutting is completed, the countertop should be cleaned in time. There may be some fabric scraps, dust and other debris left on the table surface, which will affect the quality of the next cutting. Operators can use a hoover, rags and other tools to clean the table to ensure that the table is clean and tidy. At the same time, the cut fabrics should be organised and stored in time to avoid the fabrics piling up on the table top and affecting the working environment.
6.2 Cutting effect check
After cutting is completed, check the cutting effect. The inspection includes whether the cutting size is accurate, whether the cutting edge is neat, whether there is any fabric residue, etc. If the cutting effect is found to be not in accordance with the requirements, it is necessary to check the cutting effect. If it is found that the cutting effect does not meet the requirements, the reasons should be analysed and adjusted. For example, if the cutting size is inaccurate, it may be that the parameter setting is unreasonable or the equipment is malfunctioning, and it is necessary to reset the parameter or inspect and repair the equipment.
6.3 Data Recording and Analysis
In order to continuously improve the quality and efficiency of cutting, the operator can record and analyse the data of each cutting. The record includes the type and quantity of fabrics cut, cutting time, cutting parameters, etc. By analysing these data, problems and deficiencies in the cutting process can be identified so that corresponding improvement measures can be taken. For example, if it is found that a certain kind of fabric has frequent problems in the cutting process, the cutting parameters can be adjusted or the cutting knife can be replaced in a targeted manner.
VII. Care and Maintenance of Equipment
7.1 Daily Maintenance
Daily maintenance is the basis for ensuring the normal operation of the multi-layer cutting machine equipment. Operators at the end of each day’s work, the multi-layer cutting machine to carry out simple maintenance. This includes cleaning the surface of the equipment, checking whether the various parts of the equipment are loose, and lubricating the parts that need to be lubricated. Cleaning the surface of the equipment can prevent dust and debris from entering the interior of the equipment, affecting the normal operation of the equipment. Checking whether the equipment parts are loose can avoid equipment failure caused by loose parts. Lubricating the parts that need to be lubricated can reduce the friction between the parts and prolong the service life of the equipment.
7.2 Periodic Maintenance
In addition to routine maintenance, periodic maintenance of the multi-layer cutting machine is also required. The periodicity of regular maintenance can be determined according to the frequency of use of the equipment and the manufacturer’s recommendations. Generally speaking, a comprehensive inspection and maintenance of the multi-layer cutting machine should be carried out at regular intervals. This includes replacing the cutting knives, checking the transmission system, cleaning the vacuuming system and so on. Replacing the cutting knife can ensure the quality and efficiency of cutting, as the knife will become dull after a period of use. Checking the transmission system can ensure the normal operation of the transmission system to avoid equipment downtime caused by transmission system failure. Cleaning the dust-absorbing system can ensure the dust-absorbing effect and keep the working environment clean.
7.3 Maintenance Records
In order to facilitate the management of the maintenance and repair of the equipment, the enterprise should establish an equipment maintenance record system. Operators should be detailed records of each maintenance time, content, maintenance personnel and other information. Through the maintenance records, you can understand the maintenance of equipment, timely detection of equipment problems. At the same time, the maintenance records can also be used as an important basis for equipment maintenance and management, and provide a reference for equipment renewal and upgrading.
VIII, safety control
