  Maintenance of Web laminating machine

  1. Always check the tightness and wear of the belt of the Web laminating machine. Keep the paper laminating machine suction nozzle moving freely up and down. At the same time, pay attention to the cleaning of the suction nozzle inside, and pay attention to the removal of foreign matters in the air pipe of the suction nozzle, and clean all the air valves of the air head. The linear guide bearing above the suction nozzle is lubricated once a week. Open the air cap twice every six months.

  2. Inject proper amount of grease into the bearings of the Web laminating machine every week, and inject the machine with proper amount of machine oil every week. Proper amount of gear oil should be injected into the laminating machine every month, and the oil should be changed every half a year. The filter of the vacuum pump of the equipment should be cleaned once a month, and the motor of the pressing and feeding section of the laminating machine should be changed with high-speed grease every six months.

  3. During operation, the surface of all rollers should be kept clean to avoid solid objects attached to them. Attention should be paid to the sudden expansion of COTS due to chemical solvents during operation, and the appearance of COTS should be prevented from bursting due to prolonged extrusion. When the work is finished, the coating and cots must be depressurized before work to prevent elastic fatigue caused by long-term extrusion of cots, which will affect the service life of the paper laminating machine.

  Inspection of Web laminating machine

  1. Put the samples processed by the laminating machine into the drying channel and bake at 60-65 ℃ for about 30 minutes. If there is no foaming phenomenon, no delamination, no wrinkle, it is qualified. After baking, tear off the film should not be separated from the paper. Put the sample on the indentation machine for pressure. If the concave convex part does not peel off, it is qualified; if the plastic film does not separate from the printed matter, it is qualified if the sample is soaked in cold water for 1 hour.

  2. Tear off one corner of the sample film completed by the laminating machine towards the wide direction, press and hold the paper, and tear off the whole film after tearing it in the width direction. After tearing, if the graphic imprint on the surface of the printed matter is transferred to the film along with the adhesive layer and the paper fiber, it indicates that the printed matter and the film are well bonded and are qualified products. If the samples processed by the laminating machine meet the requirements after one or more tests, they can be put into mass production. If not, the process shall be adjusted and the test shall be conducted until it is qualified.
