Abstract
Description
Technical Field
[0001] The invention relates to the field of die-cutting parts processing, in particular to a material-saving die-cutting method for C-shaped products. Background Art
[0002] The main material adhesive can effectively improve the surface polarity of the silicone material and greatly improve the bonding performance. The treated silicone can be used for double-sided adhesive on the back of silicone. At the same time, spray painting and screen printing on the silicone after treatment also have good effects. It has the characteristics of strong initial adhesion, high bonding strength, and easy use. With the development of the industry, the design of the main material adhesive has become more and more diversified, and many of the main material adhesive lamination routes are designed to be C-shaped. The existing design in the industry often laminates it on the release film for die-cutting, but its die-cutting method often causes waste of the main material adhesive, and a large amount of the main material adhesive is discharged as waste, which greatly increases the production and processing costs.
[0003] Therefore, there is an urgent need for a die-cutting method for C-shaped products that saves main rubber raw materials and reduces production costs. Summary of the invention
[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a material-saving die-cutting method for C-shaped products, save the main material glue raw material and reduce the production cost.
[0005] The purpose of the present invention can be achieved by the following technical solutions:
[0006] A material-saving die-cutting method for C-shaped products comprises the following steps:
[0007] A1. Glue the release film to the main material to form a material strip;
[0008] A2, performing a first die-cutting on the material strip along the first C-shaped product knife line group and the second C-shaped product knife line group which are arranged relatively staggered, to obtain a first C-shaped main material adhesive product and a second C-shaped main material adhesive product group;
[0009] A3, performing a second die-cutting along the serpentine separation knife line between the first C-shaped product knife line group and the second C-shaped product knife line group, so that the first C-shaped main material glue product group and the second C-shaped main material glue product group are separated from each other for easy waste discharge;
[0010] A4. Discard the strips after the first and second die-cutting;
[0011] A5. Attach the first C-shaped main material adhesive product or the second C-shaped main material adhesive product group to the handle film material, perform a third die-cut along the product outline to obtain a handle film product with a C-shaped main material adhesive product, and the processing is completed.
[0012] Further, the first C-shaped product knife line group includes a first C-shaped product knife line and a second C-shaped product knife line located below the first C-shaped product knife line. The first C-shaped product knife line and the second C-shaped product knife line enclose to form the first C-shaped main material glue product.
[0013] Further, the first C-shaped product knife line includes a first horizontal segment, a first vertical segment, a second horizontal segment, and a second vertical segment that are connected in sequence.
[0014] Furthermore, the first horizontal segment and the second horizontal segment are on the same horizontal line, the first vertical segment and the second vertical segment are parallel, and the first horizontal segment and the first vertical segment are perpendicular.
[0015] Furthermore, the first horizontal segment, the first vertical segment, the second horizontal segment, and the second vertical segment are connected by rounded corners.
[0016] Further, the second C-shaped product knife line includes a third horizontal segment, a third vertical segment, a fourth horizontal segment, and a fourth vertical segment that are connected in sequence.
[0017] Furthermore, the third horizontal segment and the fourth horizontal segment are on the same horizontal line, the third vertical segment and the fourth vertical segment are parallel, and the third horizontal segment and the third vertical segment are perpendicular.
[0018] Furthermore, the third horizontal segment and the third vertical segment are connected by an arc with the center outside.
[0019] Furthermore, the third vertical segment, the fourth horizontal segment, and the fourth vertical segment are connected by rounded corners.
[0020] Further, the first horizontal segment is parallel to the third horizontal segment, and the first vertical segment is parallel to the third vertical segment.
[0021] Furthermore, the length of the first horizontal segment is less than that of the third horizontal segment, the length of the first vertical segment is less than that of the third vertical segment, the length of the second horizontal segment is greater than that of the fourth horizontal segment, and the length of the second vertical segment is less than that of the fourth vertical segment.
[0022] Further, the second C-shaped product knife line group includes a third C-shaped product knife line and a fourth C-shaped product knife line located above the third C-shaped product knife line. The third C-shaped product knife line and the fourth C-shaped product knife line enclose to form the second C-shaped main material glue product group.
[0023] Further, the shape of the third C-shaped product knife line is the same as the shape of the first C-shaped product knife line after being flipped up and down.
[0024] Further, the shape of the knife line of the fourth C-shaped product is the same as the shape after the knife line of the second C-shaped product is flipped up and down.
[0025] Further, the snake-shaped separating knife line includes a first separating knife line, a second separating knife line, a third separating knife line, and a fourth separating knife line that are connected in sequence.
[0026] Furthermore, the second separating knife line and the fourth separating knife line are on the same horizontal line, the first separating knife line and the third separating knife line are parallel, and the first separating knife line and the second separating knife line are perpendicular.
[0027] Further, the first separating knife line is parallel to the first longitudinal section and is located on the right side of the first longitudinal section.
[0028] Further, the second separating knife line is parallel to the second transverse section and is located below the second transverse section.
[0029] Further, since the C-shaped main material glue product group has a certain thickness, and the typesetting and winding of the first C-shaped product knife line group and the second C-shaped product knife line group are too many, it is not convenient to discharge waste. Therefore, the snake-shaped separating knife line is designed.
[0030] Compared with the prior art, the present invention has the following advantages:
[0031] The present invention performs the first die-cutting along the first C-shaped product knife line group and the second C-shaped product knife line group arranged relatively staggeredly to obtain the first C-shaped main material glue product and the second C-shaped main material glue product group. This method is beneficial to optimizing the cost of C-shaped die-cut products and greatly improves the material utilization rate. Subsequently, the second die-cutting is performed along the snake-shaped separating knife line between the first C-shaped product knife line group and the second C-shaped product knife line group, which is convenient for separating the products and is beneficial to the waste discharging process. At the same time, it avoids additional die-cutting processes and optimizes the process. BRIEF DESCRIPTION OF THE DRAWINGS

The second C-shaped product knife line 12 is a zigzag line with undulations, and the central axis of its concave and convex parts is the same as that of the first C-shaped product knife line 11. After die-cutting along the first C-shaped product knife line group 1, the first C-shaped main material glue product group 41 is obtained.

The shape of the fourth C-shaped product knife line 22 is the same as the shape after the second C-shaped product knife line 12 is turned upside down. After die-cutting along the second C-shaped product knife line group 2, the second C-shaped main material glue product group 42 is obtained. The second C-shaped main material glue product group 42 is formed by connecting a number of main material glue products 43 in the shape of a C, and the overall shape is concave and convex. After being turned over, its shape is the same as that of the first C-shaped main material glue product group 41.
[0057] In this embodiment, the serpentine separating knife line 3 includes a first separating knife line 31, a second separating knife line 32, a third separating knife line 33, and a fourth separating knife line 34 connected in sequence.

[0059] The method performs the first die-cutting along the first C-shaped product knife line group 1 and the second C-shaped product knife line group 2 arranged in relative staggered layout to obtain the first C-shaped main material glue product 41 and the second C-shaped main material glue product group 42, which is beneficial to optimizing the cost of C-shaped die-cut products and greatly improving the material utilization rate. Subsequently, the second die-cutting is performed along the serpentine separating knife line 3 between the first C-shaped product knife line group 1 and the second C-shaped product knife line group 2 to facilitate separating the products and performing the waste discharging process, while avoiding additional die-cutting processes and optimizing the process.
[0060] Comparative Example 1
[0061] See Figure 4, a die-cutting method for C-shaped products, comprising the following steps:
