Embodiment 1
[0032] see Figure 1-3 , the present invention provides a technical solution: a method for preparing a multi-section up and down tearing hand protective film, comprising the following steps:
[0033] S1. First place the material one through the discharge shaft L2, and then connect G1-G2 through the correction device to cut down the D1 knife die in the cutting abrasive tool, cut through the material one with its own film, and cut in half on the main material;
[0034] S2. Place the material 2 through the lower material shaft D2, and attach the film to the material 1 through the G3 station;
[0035] S3, G6-G7 repost two ST-5534SB+A1#23 through 5002G, put the rubber side up, discharge the waste A1#23 through the G7 upper rubber roller, cut off the ST-5534SB rubber side with the knife die D3 on G6, Collect outer frame waste through U6;
[0036] After S4 and G7, the scraper is put on, and the waste is discharged to 5002G. The material is bonded to the knife die D4 on G9 through G...

Abstract
The invention discloses a preparation method of a multi-section up-and-down tearing hand protective film, and belongs to the field of die cutting. The preparation method is characterized by comprising the following steps: S1, placing a material I through a discharging shaft L2; connecting G1-G2 in series through a deviation corrector; cutting down a cutting die D1 in a cuttinggrinding tool; cutting through a film of the material I; half-cutting on a main material; S2, placing a material II through a lower material shaft D2, and attaching the second material to a film of the first material through a station G3; S3, repasting ST-5534SB + A1 # 23 for two times on G6-G7 through 5002G; enabling the glue surface to face upwards; discharging waste A1 # 23 through a G7 gluing roller; cutting off the glue surface of ST-5534SB through a cutting die D3 on G6; collecting outer frame waste through U6; S4, assembling a scraper behind G7; discharging waste 5002G; attaching the material to a cutting die D4 on G9 through G8; cutting the outer frame of the product; then discharging waste through U10; and S5, enabling the material to pass through a toothed rubber roller mounted on G10; then mounting the scraper to scrape out the product; and discharging waste TWS5001 through D7 so as to solve the problems of certain process difficulty and lower manufacturing precision of an existing up-down tearing hand protective film.
Description
technical field [0001] The invention relates to the field of die-cutting, in particular to a preparation method of a multi-stage up and down tearing hand protection film. Background technique [0002] According to the purpose, the protective film can be divided into digital product protective film, car protective film, household protective film, food preservation protective film, etc. Electronic components such as mobile phone screens, liquid crystal displays and polarizers have precise structures and are relatively expensive. During transportation and use, due to bumping, clamping and scratches or other damages, a layer of electrostatic protective film is usually pasted on the surface of the above-mentioned electronic components, which not only protects the safety of electronic components, but also prevents static electricity from affecting electronic components or other electrical components. Parts cause damage. With the popularization of mobile phones and other digital pr...
