Common faults and elimination of automatic laminating machine:
        1. Horizontal wrinkles. This is due to the fact that the longitudinal tensile force of the mulch is less than the lateral tensile force, and the forward speed is uneven.
        Solution: reduce the pressure of the left and right pressure film wheels; increase the clamping force of the film roll; the unit's forward speed should be uniform and consistent.
        2. Longitudinal wrinkles. This is due to the fact that the longitudinal tensile force of the mulch film is greater than the lateral tensile force.
        Solution: increase the pressure of the left and right pressure film wheels; reduce the clamping force of the film roll; appropriately reduce the forward speed of the unit.
        3. Diagonal wrinkles. The reason is that the unit failed to drive straight, or the pressure of the left and right pressure wheel is not consistent.
        Solution: Improve the operation technical level and make the unit run straight; adjust the two pressure film wheels to make the pressure even and consistent.
        4. Deflected mulch. It is caused by the failure of the unit to drive in a straight line, or the installation of the film roll is not correct, and the film roll itself is not properly wound.
        Solution: Realign the film roll to the front side and perpendicular to the direction of advance of the unit; the unit should travel at a uniform speed and straight line; check the film roll and replace it if necessary.
        5. The film pressing wheel can't hold the mulch. This is due to the reasons that the unit is not running properly, the width of the film is not matched with the border surface, and the quality of the film itself is not good. It should be solved according to the specific situation.

        6. After the film is spread, the curling and both sides are broken. For the occurrence of curling, the pressure of the film pressing wheel should be increased, the deflection angle of the soil shovel should be reduced, and the distance between the soil shovel and the mulch film should be adjusted. If the film breaks, the pressure of the two pressure film wheels should be reduced, and the quality of the land preparation should be checked.
