Description

Technical Field

[0001] This invention relates to the field of nesting cutting processes, and particularly to a nesting cutting process using a circular knife and a flat plate. Background Technology

[0002] Currently, in the die-cutting industry, products are generally processed using either pure flatbed cutting or pure rotary cutting. Pure flatbed cutting not only has low production capacity and significant limitations, but also produces unstable cutting marks, which can easily lead to product defects. Pure rotary cutting, on the other hand, suffers from low cutting accuracy and unstable dimensions, which can also result in product defects. Therefore, using only one of these two processes often leads to defects and increases production costs. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a circular die-cutting and flat die-cutting process that combines a circular die-cutting machine and a flat die-cutting machine. The circular die-cutting machine performs die-mark-free processing, while the flat die-cutting machine performs die-cutting. This maximizes the stability of the die marks and dimensions, ensuring both efficient product processing and high die-cutting precision, while reducing manufacturing costs.

[0004] According to one aspect of the present invention, a circular cutter and a flat cutter are provided for a combined cutting process, applied to a circular cutter machine with at least eight workstations and a flat cutter, comprising the following steps: S1: At the first station of the circular knife machine, a material strip protective film is laminated on a first bottom protective film; S2: At the first station of the circular die-cutting machine, a waste discharge protective film is laminated on the bottom layer of the first bottom protective film to form a film material, and the discharge strip is die-cut and the positioning holes are die-cut on the film material. S3: At the third station of the rotary cutter, a release protective film is laminated onto the top layer of the film material; S4: At the fourth station of the rotary die-cutting machine, a first release masking film is laminated onto the release protective film, and the first release masking film is die-cut. S5: At the sixth station of the rotary cutter machine, a second release masking film is laminated onto a second bottom protective film, and then flipped together and laminated onto the top layer of the film material. S6: At the eighth station of the rotary cutter, a cover film is laminated onto the top layer of the film material; S7: Use a flatbed cutter to cut the film material to create the shape and puncture line of the first release mask; S8: Waste removal and finishing of the film material to obtain the formed product.

[0005] In some embodiments, in step S2, after die-cutting, the waste material with its own protective film is removed. This is advantageous because removing waste after cutting out the adhesive-coated material strip and cutting the positioning holes facilitates subsequent processing.

[0006] In some embodiments, the self-contained film of the release liner is further removed in step S3. The advantage of this is that removing the self-contained film of the release liner makes it suitable for subsequent lamination processes.

[0007] In some embodiments, in step S4, the release surface of the first release masking film faces downwards. The advantage is that it describes the specific manner in which the first release masking film is laminated.

[0008] In some embodiments, in step S4, after die-cutting, the waste material and hole waste of the first release mask are removed. This is advantageous because after die-cutting, the first release mask needs to be removed to facilitate subsequent processing.

[0009] In some embodiments, in step S5, the waste material of the second release mask is also cut and removed at the fifth station of the rotary cutter. The advantage of this is that cutting and removing the waste material of the second release mask allows the second release mask to be smoothly laminated to the top layer of the film material.

[0010] In some embodiments, in step S5, the second release liner is laminated onto the second backing liner with the release surface facing upwards, and onto the film material with the release surface facing downwards. This is advantageous because it describes the specific position of the second release liner during the two lamination processes.

[0011] In some embodiments, in step S6, the waste material of the second bottom protective film is first removed at the seventh station of the rotary cutter. The advantage of this is that removing the waste material of the second bottom protective film first facilitates the lamination of the cover film. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] like Figure 1As shown, the present invention provides a circular knife and flat plate inline cutting process. This process is mainly implemented by a circular knife machine 10 and a flat knife inline cutting machine 20. Each circular knife machine 10 includes multiple workstations arranged sequentially from one end (set as the left end and the other end as the right end) (eight workstations in this embodiment).

[0016] The implementation of this process includes several main steps, as described below.

[0017] S1: At the first station of the circular cutter machine 10, a first bottom protective film 1 and a material strip protective film 2 are laminated together. The material strip protective film 2 is laminated on top of the first bottom protective film 1.

[0018] Preferably, the thickness of the first bottom protective film 1 is 0.075 mm, and the thickness of the material strip protective film 2 is 0.08 mm.

[0019] S2: At the second station of the circular knife machine 10, a waste discharge protective film 3 is laminated on the bottom layer of the first bottom protective film 1 to form a film material. Then, the circular knife (i.e., knife A in the figure) on it is used to cut the material strip adhesive masking and positioning holes on the film material, and then the waste material of the material strip protective film 2 is removed.

[0020] Preferably, the thickness of the waste discharge protective membrane 3 is 0.055 mm. S3: At the third station of the circular knife machine 10, a release protective film 4 is laminated on the top layer of the film material, and then the film attached to the release protective film 4 is removed.

[0021] Preferably, the thickness of the release protective film 4 is 0.085 mm.

[0022] S4: At the fourth station of the rotary die-cutting machine 10, a first release masking film 5 is laminated onto the release protective film 4. Then, the rotary die (i.e., die B in the figure) is used to die-cut the first release masking film 5, and the waste material and hole waste of the first release masking film 5 are removed.

[0023] In this case, the release surface of the first release masking film 5 faces downward, that is, it is attached to the release protective film 4.

[0024] Preferably, the thickness of the first release masking film 5 is 0.012 mm.

[0025] S5: At the fifth and sixth stations of the rotary cutter machine 10, a second release masking film 6 is laminated onto a second bottom protective film 7, and the waste material of the second release masking film 6 is cut and removed using a rotary cutter (i.e., cutter C in the figure). Then, the second release masking film 6 and the second bottom protective film 7 are flipped over and laminated onto the top layer of the film material, so that the first release masking film 5 produces a knife mark-free effect.

[0026] Specifically, when the second release liner 6 is applied to the second backing protective film 7, the release surface of the second release liner 6 faces upwards; however, when it is laminated onto the film material, the release surface of the second release liner 6 faces downwards. Preferably, the thickness of the first bottom protective film 1 is 0.05 mm.

[0027] S6: At the seventh and eighth stations of the circular knife machine 10, the waste material of the second bottom protective film 7 and the composite cover film 8 on the top layer of the film material are removed in sequence.

[0028] S7: Pull the film material onto the flat knife cutting machine and use the engraving mold to cut the film material to cut out the shape and puncture line of the first release masking film 5.

[0029] S8: After the cutting process is completed, the film material is cleaned and tidied up as needed to obtain the finished product.

[0030] This invention provides a circular knife and flat plate interconnected cutting process, which has the following advantages: 1. By combining a rotary cutter and a flatbed cutting machine, the rotary cutter performs blade-free processing, while the flatbed cutting machine performs nesting processing, thereby maximizing the stability of blade marks and dimensions; 2. It ensured efficient product processing and saved manpower and time; 3. It has high die-cutting precision, which reduces production and manufacturing costs.

[0031] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
