The waste discharge method is realized based on the waste discharge device, can realize quick waste discharge by utilizing the waste discharge device, is simple and convenient to operate, and can greatly improve the waste discharge efficiency of the protective film waste.

Example 2

Referring to fig. 12, this embodiment is substantially the same as embodiment 1, except that two sets of waste discharge devices are symmetrically disposed on the frame 1, and the central axes of the driving rollers 4 in the two sets of waste discharge devices are perpendicular to the central axis of the conveying roller group 3; the driving mode of the driving rollers 4 in the two groups of waste discharge devices can adopt a motor independent driving mode or a mode of connecting the existing transmission mechanism with the conveying roller group 3.

It should be noted that the rotation speed of the two driving rollers 4 should be ensured to be the same to avoid the inclination of the main body 2.

The two sets of waste discharge devices are designed to be able to collect the already halved protective film individually (part of the protective film is split in half in the axial direction of the tape body 2 for process reasons), improving the collection efficiency.

In conclusion, the automatic collection device can automatically collect the protective film waste, and greatly reduces the labor cost and the rejection rate of products while ensuring the waste discharge efficiency.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
