[0002] With the development of the industry, in the die cutting industry, there is an increasing demand for the automated design of die cut product coils. The existing circular die design process for the roll material matching line in the industry requires a relatively wide original material of the roll material tape, resulting in a large waste of the original material, an increase in product cost, and a lack of competitiveness.
[0003] Therefore, there is an urgent need for a circular die cutting process that saves the raw material cost of the roll material tape. Summary of the Invention
[0004] The purpose of the present invention is to overcome the above-mentioned defects existing in the prior art and provide a circular die cutting process for a roll material matching line, which saves raw materials and reduces costs.
[0005] The purpose of the present invention can be achieved by the following technical solutions:
[0006] A circular die cutting process for a roll material matching line includes the following steps:
[0007] A1. Attach the roll material tape to the carrier film and convey it to the corresponding position;
[0008] A2. Perform die cutting along the roll material product line through the circular die cutting process to obtain a number of roll material products;
[0009] A3. Set a number of matching lines above the roll material products;
[0010] A4. Select the horizontal direction of the matching line as the position and direction of the trimming line, and perform upper and lower trimming through the circular die cutting process to complete the processing.
[0011] Further, the roll material product line is die cut by high and low knives.
[0012] Further, the matching line includes horizontal and vertical lines with single-point crossing or multi-point crossing.
[0013] Further, the shape of the matching line includes cross-shaped, I-shaped, lightning-shaped, L-shaped, and Z-shaped.
[0014] Further, the number of the matching lines is 1 to 10, preferably 2 to 4.
[0015] Further, the distance between the matching line and the roll material product is greater than the thickness of the circular die and less than the width of the carrier film.
[0016] Further, the trimming line is the same length as the roll material product.
[0017] Furthermore, the trimming line has a first trimming line and a second trimming line. The first trimming line is located at the matching line, and the second trimming line is parallel to the first trimming line.
[0018] Even further, the first trimming line is located above the coiled material product.
[0019] Even further, the second trimming line is located below the coiled material product.
[0020] Compared with the prior art, in the present invention, the matching line is designed at the edge trimming position of the strip material, and the trimming line is directly cut at the horizontal position of the matching line in the previous process, solving the problem of the increase in the width of the raw material caused by the design of the matching line, saving paper costs, and increasing the competitiveness of the product in the industry.

[0031] Example 1
[0032] A circular knife die-cutting process for a coiled material matching line includes the following steps:
[0033] A1. Bond the coiled material tape to the carrier film and transport it to the corresponding position;
[0034] A2. Perform die-cutting along the coiled material product line 1 through the circular knife die-cutting process to obtain a number of coiled material products;
[0035] A3. Set a number of matching lines 3 above the coiled material products;
[0036] A4. Select the lateral direction of the matching line 3 as the position and direction of the trimming line 2, and perform upper and lower trimming through the circular knife die-cutting process to complete the processing.
[0037] In this embodiment, the coiled material product line 1 is die-cut by high and low knives.
[0038] In this embodiment, the matching line 3 is an L-shaped that is horizontally mirror-inverted. The number of the matching lines 3 is 2.
[0039] In this embodiment, the trimming line 2 is the same length as the coiled material product. The trimming line 2 has a first trimming line 201 and a second trimming line 202. The first trimming line 201 is located at the matching line 3, and the second trimming line 202 is parallel to the first trimming line 201. The first trimming line 201 is located above the coiled material product, and the second trimming line is located below the coiled material product.
[0040] In this embodiment, the position of the trimming line 2 is fixed. The matching line 3 is designed at the edge trimming position of the tape. The trimming line is directly cut at the horizontal position of the matching line in the previous process, solving the problem of the increase in the width of the raw material caused by the design of the matching line 3, saving costs, and increasing the competitiveness of the product in the industry.
[0041] Comparative Example 1
[0042] A circular knife die-cutting process for a coiled material matching line includes the following steps:
[0043] A1. Bond the coiled material tape to the carrier film and transport it to the corresponding position;
[0044] A2. Perform die-cutting along the roll material production line 1 through a round knife die-cutting process to obtain a number of roll material products;
[0045] A3. Set a number of matching lines 3 above the roll material products;
[0046] A4. Below the matching line 3 and parallel to the transverse direction of the matching line 3, perform trimming through a round knife die-cutting process to complete the processing.
[0047] In this comparative example, the roll material production line 1 is die-cut by high and low knives. The matching line 3 is in a cross shape. The number of the matching lines 3 is 2. In this comparative example, the trimming line 2 is the same length as the roll material product. The trimming line 2 has a first trimming line 201 and a second trimming line 202. The first trimming line 201 is located at the matching line 3. The second trimming line 202 is parallel to the first trimming line 201. The first trimming line 201 is located above the roll material product, and the second trimming line is located below the roll material product. The position of the trimming line 2 is fixed. The matching line 3 is designed above the trimming position of the tape edge, making the distance between the matching line 3 and the roll material product greater than the distance between the trimming line 2 and the roll material product, resulting in the need to increase the tape width, waste of raw materials, and an increase in product cost.
[0048] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, based on the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
