Automatic feed die-cutting machine is an important production equipment in color box packaging, carton processing, label printing, commercial printing and so on. With the continuous improvement of automation of equipment, the precision of die cutting and the efficiency of production have been significantly improved. However, even the most advanced equipment cannot be maintained and maintained without science. Standardized daily maintenance can not only reduce downtime caused by faults, but also extend the service life of equipment, reduce maintenance costs and maintain stable die quality.
So, what should be noticed in the routine maintenance of fully automatic refueling die-cutting machines? Below, we break it down in six ways.
1, Clean equipment and keep operating environment clean.
Equipment cleaning is one of the most basic and important tasks in daily maintenance. During the die-cutting process, a large amount of paper scraps, dust and waste is produced. If accumulated over a long period of time, it may not only affect the accuracy of the feed, but also enter the transmission system and accelerate the wear and tear of components.
After daily production, operators should thoroughly clean the paper feeding table, die-cutting area, paper receiving device, waste paper removal system and the inside of the body. Soft cleaning tools should be used for key components such as sensors, photoelectric detection devices and guide rails to avoid scratchings on hard objects or to affect the accuracy of detection.
Keeping the environment around the device clean also helps reduce the risk of dust getting inside.
2. Regular lubrication transmission system.
Automatic feeding die cutting machine includes gears, chains, bearings, guides, cams and other moving parts, and requires good lubrication during high-speed operation.
The enterprise shall draw up a lubrication plans in accordance with equipment manuals, regularly inspect lubrication points and use lubricating oil or grease recommended by the manufacturer to avoid parts wear and tear, elevated temperature or increased noise due to insufficient lubrication.
At the same time, excessive refueling should be avoided. Too much lube can contaminate paper or die cutting boards, affecting product quality. Therefore, appropriate, regular, and standardized lubrication should be achieved.
3. Check feed systems and positioning device
Automatic feeding system directly affects the die cutting efficiency and machining accuracy and requires key maintenance.
Before starting each day, check the suction nozzle, suction system, paper feeding belt, front gauge, side gauge, positioning mechanism to ensure that the paper transportation is smooth, no tilt, double slice, paper jams.
If the feed is found to be unstable, clean the suction nozzle, adjust the air pressure or check the abrasion area in time to avoid positioning deviation of the whole batch size and increase the scrap rate.
4. Check die-cutting board and indentation system regularly.
Die-cutting plate is an important component of product processing quality. After long-term use, the cutting edge may be worn, dull or partially deformed, affecting the cutting quality.
In the production process, to regularly check whether the die cutting blade is installed firmly, whether the blade is sharp and whether the indentation line is complete. If the incision has burrs, continuous cutting or indentations are not obvious, the cutting plate should be repaired or replaced in time.
In addition, die-cutting pressure and positioning parameters should be readjusted every time the product is replaced to ensure that the product of different specifications is of good processing quality.
5. Check electrical systems and safety devices.
Modern automatic feed die-cutting machine usually adopts PLC control system, touch screen operation interfaces and various safety protection devices. In order to ensure the steady operation of the equipment, the electrical system should be inspected regularly.
Maintenance includes checking that circuit connections are secure, that control cabinet are clean, that buttons and emergency stop switches are sensitive, that the photoelectric protection device works properly, and that various sensors give accurate feedback.
At the same time, safety protection devices should be regularly tested to ensure that the doors, safety interlocks and alarm systems can operate normally, providing reliable safety guarantees for operators.
6, Establish equipment maintenance system and maintenance records.
The maintenance of equipment should not depend solely on the repair of breakdowns, but should also establish a comprehensive system of preventive maintenance.
The enterprise may establish daily inspection, weekly maintenance, monthly maintenance and annual maintenance overhaul plans according to the operation time of the equipment, and establish detailed equipment maintenance records, record lubrication, replacement of parts, fault causes and repair situations.
Through data analysis and maintenance, potential equipment problems can be identified in a timely manner, spare parts procurement and maintenance plans can be rationalized, downtime can be reduced abruptly, and equipment utilization and productivity can be improved.
At the same time, strengthening the training of operators to familiarize them with equipment structure and routine maintenance procedures is also an important measure to ensure the long-term stable operation of equipment.
Abstracts
The steady operation of automatic feed die-cutting machine depends not only on the performance of the equipment itself but also on standardized daily maintenance. By cleaning equipment, standardizing lubrication, maintaining feeding systems, inspecting die cutting board and electrical system, and establishing perfect maintenance system, enterprises can effectively reduce equipment failures, prolong service life and maintain stable die cutting quality.
For packaging printing enterprises, adherence to preventive maintenance can not only reduce maintenance costs, but also improve production efficiency, reduce waste rates, and create higher economic benefits for enterprises.
