A porous semi-broken overflow adhesive waste disposal process

Abstract

This invention provides a process for solving the problem of overflowing adhesive in porous semi-continuous release film. For this type of difficult-to-remove overflowing adhesive, the inner hole is first designed to be completely cut off to absorb the waste. Then, the inner hole is partially cut off by transferring the positioning hole to another release film and punching through the film replacement. This process completely eliminates the problem of difficult-to-remove overflowing adhesive in the inner hole, and improves the yield and production efficiency.

Description

Technical Field

[0001] This invention relates to a processing technology, and more particularly to a processing technology for adding web to foam. Background Technology

[0002] The existing process results in partial cutting of the inner hole, glue overflow at the edge of the inner hole, difficulty in removing waste material from the inner hole, and direct fuzzing of the glue tape at the edge of the inner hole. Summary of the Invention

[0003] The main technical problem to be solved by the present invention is to provide a process for removing excess glue from porous semi-broken holes, which completely eliminates the problem of difficult waste removal of excess glue from inner holes and improves yield and production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a porous semi-broken overflow adhesive waste disposal process, comprising the following steps:

[0005] 1) The first release film and foam adhesive are conveyed to the first processing station. During the conveying process, there is a preset angle between the release film and the foam adhesive, and the release surface of the release film faces upward. At the first processing station, the release surface of the release film is bonded to the adhesive surface of the foam adhesive, and the paper attached to the foam adhesive is removed.

[0006] 2) At the second processing station, the release surface of the second release film is bonded to the side of the foam adhesive away from the first release film;

[0007] 3) At the third processing station, use a flat knife to punch the second release film surface, completely cut off all holes and remove waste, cut the upper and lower edge knives halfway to the blue film, and remove the surface matte film;

[0008] 3) At the fourth processing station, the release surface of the third release film is bonded to the non-release surface of the second release film, and then the adhesive surface of the protective film is bonded to the non-release surface of the third release film;

[0009] 4) At the fifth processing station, use a flat knife to punch the protective film surface, completely cutting off all holes to remove waste, and partially cutting off the lettering to the first release film;

[0010] 5) At the sixth processing station, flip the strip 180° and remove the first release film, then attach the release surface of the fourth release film to the adhesive surface with foam adhesive.

[0011] 6) At the seventh processing station, use a flat knife to punch the fourth release film surface, cutting all the cut lines halfway to the protective film, removing the outer blue film and glue waste, and removing the surface matte film by adhesive bonding.

[0012] 7) At the eighth processing station, apply transparent tape to the non-release surface of the fourth release film;

[0013] 8) At the ninth processing station, use a flat knife to cut the transparent tape side, cutting halfway down to the protective film, and remove the waste from the top and bottom ends of the fog film; peel off the protective film, attach the white grid paper to the blue film side of the product, and roll up the finished product with the inward side.

[0014] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0015] This invention provides a process for solving the problem of overflowing adhesive in porous semi-continuous release film. For this type of difficult-to-remove overflowing adhesive, the inner hole is first designed to be completely cut off to absorb the waste. Then, the inner hole is partially cut off by transferring the positioning hole to another release film and punching through the film replacement. This process completely eliminates the problem of difficult-to-remove overflowing adhesive in the inner hole, and improves the yield and production efficiency. Attached Figure Description
