Problems solved by technology

But this processing method has the following problems: 1, although this method has reduced the waste material of black inner film, still need to manually remove the waste material of a small amount of black inner film, compares waste of time, and can't make process complete continuously; 2, directly The black inner film jumps and cuts on the original film, which is easy to leave traces of the roller knife on the original film, which affects the quality of the final protective film; 3. The roller knife for jump cutting is generally cut from top to bottom, and the roller knife cuts by gravity , it is easy to leave traces of roller knives on the original film

Embodiment 1

[0024] The processing method of jump-cut type double-sided adhesive tape comprises the following steps:

[0025] The first step, feeding: First, install the release paper and the inner film on the feeding roller respectively. The release paper is conveyed continuously, and the inner film is conveyed intermittently. The step distance between the release paper and the inner film is different, generally The step distance of the inner film is greater than the step distance of the release paper, and the difference between the step distance of the inner film and the step distance of the release paper is 5mm. For this reason, the step distance of the release paper is 8mm, and the step distance of the inner film is 13mm, which is convenient for the jump cutting of the inner film, and a space is formed between the inner films on the release paper. Wherein the release paper is located above the inner film, and both the release paper and the inner film are arranged obliquely, and the inc...

Embodiment 2

[0029] Example 2 differs from Example 1 in that the step distance of the release paper is 9 mm, the step distance of the inner film is 14 mm, and both the release paper and the inner film are arranged obliquely, and the inclination angle is 35 degrees.

Embodiment 3

[0030] Example 3 differs from Example 1 in that the step distance of the release paper is 10 mm, the step distance of the inner film is 15 mm, and both the release paper and the inner film are arranged obliquely, and the inclination angle is 45 degrees.

Abstract

The invention relates to the technical field of computer shell protection films, in particular to a processing method for jump cutting type double faced adhesive tape. The processing method comprises the steps of feeding, jump cutting, pressing and cutting forming. An inner film is directly cut into the shape of a formed inner film, and the procedures of a protection film can be completed continuously; and the inner film is cut on release paper through jump cutting firstly, then a jump-cut film and an original film are pressed, tool marks are prevented from being directly printed on the original film, and the quality of the protection film is ensured.

Description

technical field [0001] The invention relates to the technical field of protective films for computer casings, in particular to a processing method for jump-cut double-sided adhesive tape. Background technique [0002] With the development of society, tablets or laptops need to be dustproof and protected accordingly. For this reason, a protective film is required for lamination. Such as figure 1 As shown, the traditional protective film includes the original film 1, the black inner film 2 on both sides and the release paper 3 from top to bottom, wherein the black inner film 2 is convenient for fixing. However, the traditional film cutting machine uses the whole black inner film 2 to fit on both sides of the original film 1. During the cutting process, most of the black inner film 2 will be cut, and the black inner film 2 with a fixed convex structure will remain. This film cutting method will cause a large amount of black inner film 2 waste, the waste reaches at least 50%, ...
