Causes of tension control system failure of Web paper composite machine

  Web paper composite machine is to coat the rolled substrate (such as paper, cloth, leather, aluminum foil, plastic film, etc.) with a layer of glue, paint or ink with specific functions, and then take up the roll after drying.

Composite Machine

  During the operation of Web paper composite machine, the problem of transmission part wear often occurs, such as the wear of dryer shaft head of coater, the wear of roll bearing chamber, etc. The traditional repair methods include surfacing, thermal spraying, brush plating and so on, but there are some disadvantages.

  Surfacing can make the surface of parts reach high temperature, cause deformation or cracks, and even cause shaft fracture in serious cases; Electroplating coating can not be too thick, and the pollution is serious, the application is also limited.

  If the tension control system of the laminating machine fails. The magnetic powder brake of the tension control system should be carefully checked. After the test run of the empty machine, it is found whether there is any problem.

  Solution: put the unwinding roll on the unwinding gear, turn off the power supply for manual rotation test, the feeling should be loose, and the resistance should be very small. When the magnetic powder controller is turned on and the tension is adjusted, the feeling should be that there is a certain resistance moment, but it can rotate, indicating that the brake is normal, on the contrary, it indicates that there is a fault.
