Embodiment 1

[0020] Example 1 takes figure 1 The protective film product of the shape shown is taken as an example to illustrate the technical solution of the present invention. The protective film product shown in Example 1 is in the shape of a square as a whole and the corners of the square are smoothly transitioned. According to the line characteristics and process requirements of the protective film product frame, the protective film The product frame is divided into four knife lines clockwise along the line trend: upper knife line 100, right knife line 200, lower knife line 300 and left knife line 400; according to customer requirements, the level between two adjacent protective film products Spacing a0=6mm, vertical spacing b0=5mm;

[0021] Flat knife die-cutting process for the production of the above protective film products, such as figure 2 and 3 As shown, correspondingly, the knife mold for die-cutting the protective film product is provided with four blades for cutting the f...

Abstract

The present invention aims at the problem that the die-cut frame in the prior art is easy to produce embossing, etc., and provides a flat-plate die-cutting process, which is used for the die-cutting of the frame of the protective film product, and is characterized in that: according to the line characteristics and the According to the process requirements, the frame of the protective film product is split into N knife lines along the line trend. Correspondingly, the knife die used for die-cutting the protective film product is provided with N blades for cutting the N knife lines. The N blades are arranged equidistantly along the horizontal direction, and the distance between two adjacent blades is recorded as the column spacing a1, and the column spacing a1 is equal to the horizontal spacing a0 between adjacent two protective film products, for The moving step s of the material tape of the die-cutting protective film product on the die-cutting machine is equal to the column spacing a1; wherein, N>1 and N is an integer. The present invention effectively reduces the probability of embossing and crushing of products obtained by die-cutting by removing the knife, and greatly improves the yield rate of the process.

Description

technical field [0001] The invention belongs to the technical field of die-cutting, and in particular relates to a die-cutting process for removing a knife from a flat plate. Background technique [0002] In the current die-cutting industry, when manufacturing small-sized products, the process of forming the outer frame is generally adopted. However, problems such as product outer frame crushing, embossing, and waste disposal often occur during the manufacturing process, so the defective rate of the process is relatively high. High, the production cost is too high, resulting in low product market competitiveness. Contents of the invention [0003] The present invention aims at the problem that the die-cut frame is easy to produce embossing in the prior art, and provides a die-cutting process of a flat plate with a knife removed. process yield. [0004] The present invention adopts following technical scheme: [0005] A die-cutting process with a flat knife, used for die...
