The problem of empty sheets of the folder gluer is caused by many factors, and the common reasons are as follows:

1. The quality of the cardboard itself is too light, or it is curled, and there is too much paper powder, which will cause empty sheets.

Solution: increase the weight of the paper, or arrange the cardboard, and at the same time flatten the cardboard and shake off the paper powder can be a good solution.

2. The quality of cardboard is too light, the stack is not high enough, and the operator does not add cardboard, so the friction force of the equipment is not enough and empty sheets appear.

Solution: Only the operator needs to add cardboard regularly.

3. The angle of the support bar of the folder-gluer is too high, which causes the cardboard to not be in good contact with the equipment, resulting in empty sheets.

Solution: Adjust the height of the support rod and keep it at an appropriate height.

4. Due to the aging of the folder-gluer belt, slipping occurs.

Solution: roughening the belt to increase its surface roughness, or adding an air jet device can solve this problem well.

The above are the reasons and solutions for several common empty sheets during the operation of the glue box. I hope it can effectively help everyone.
