Problems solved by technology

The position of the die-cut opening on the mold protective film prevents the easy-to-tear sticker from being able to bear the force so well that it cannot assist the tear-off of the protective film. The easy-to-tear sticker is attached manually, and some are irregular. The easy-to-tear sticker is attached to the protective film The combined area cannot be well overlapped, so that the tearing of the protective film cannot be well assisted, and the appearance of the obtained protective film is not beautiful enough.

Embodiment 3

[0036] A kind of processing technology that is easy to tear and paste protective film, adopts the processing device of preferred embodiment 1 of the present invention, comprises following processing steps:

[0037] 1) Die cuts on the protective film: place the protective film material with the protective layer 2 and the release film 1 on the die-cutting machine, place the protective layer with the adhesive side up, and then follow the direction of the protective film raw material conveying Place the first mold base 4 and the second mold base 6 in turn on the die-cutting machine, then place the protective film mold on the first mold base, and punch out the shape consistent with the product to be laminated by the punching knife set of the protective film mold Protective film products, and die-cut the first incision in the shape of "one" on the protective layer of the protective film;

[0038]2) Die-cut easy-to-tear paste: place the easy-to-tear paste mold on the second mold base...

Embodiment 4

[0040] A kind of processing technology that is easy to tear and paste protective film, adopts the processing device of preferred embodiment 1 of the present invention, comprises following processing steps:

[0041] 1) Die cut on the protective film: place the protective film material with the protective layer and the release film on the die-cutting machine, place the protective layer with the adhesive side up, and then place it on the die along the direction of the protective film raw material delivery. Place the first mold base and the second mold base in turn on the cutting machine, then place the protective film mold on the first mold base, and punch out the protective film product with the same shape as the product to be pasted through the punching knife set of the protective film mold. And on the protective layer of the protective film, punch out a square traction block with three sides separated from the protective film;

[0042] 2) Die-cut easy-to-tear paste: place the ...

Abstract

The invention discloses a processing device and a processing technology for protective films with pull tapes. The processing device for the protective films with the pull tapes comprises a die-cutting machine, a first die holder and a second die holder are sequentially arranged along the conveying direction of protective film raw materials on the die-cutting machine, a protective film die is placed in the first die holder, a pull tape die is placed in the second die holder, and manipulators of the die-cutting machine control the protective film die and the pull tape die to operate. The processing technology includes the steps of die-cutting kerfs on the protective films and die-cutting the pull tapes. The problems of inconvenience in tearing down and unattractiveness due to the fact that bonding areas of the pull tapes and the protective films cannot be well coincided resulting from manual bonding in a protective film production process in the prior art are solved.

Description

[0001] technical field [0002] The invention relates to a production process of a protective film, in particular to a processing device and a processing process for an easy-to-tear protective film. [0003] Background technique [0004] The protective film is to prevent the product from being scratched or damaged due to accidental friction, collision, etc. during the production or transportation of electronic products. Since the protective film is a process protection, it needs to be torn off in the next process. Therefore, not only is the protective film required to have a certain degree of stickiness, but it is also required to be easily torn off from the product. The easy-to-tear sticker is composed of a sticky part and a colored tear-off part. How to make the protective film and the easy-to-tear bond well, and to facilitate the tear-off is the key step in the processing of the protective film. [0005] The existing processing method is to first punch the raw mater...
