Description

Technical Field

[0001] This utility model belongs to the field of die-cutting technology, and relates to a die-cutting system, and more particularly to a fabric substrate die-cutting device. Background Technology

[0002] Die-cutting is a process that uses precision machining and cutting to form a specific structure from a substrate according to a predetermined shape. There are many types of substrate materials, among which fabric substrates have strong stability and conductivity, making them widely used in many fields. However, this also results in stringent quality control requirements. Specifically, the die-cutting process for fabric substrates presents the following problems: many fabric substrate products require zero control over abnormal fiber breakage, i.e., minimizing the generation of fiber breakage burrs. However, this is difficult to achieve with existing die-cutting technologies because fabric substrates are fibers. Although they become slightly more stable after being bonded with adhesive, the cutting process removes layers of adhesive and fabric fibers, indirectly damaging the fabric fiber structure and creating fiber breakage burrs. Utility Model Content

[0003] This invention provides a fabric substrate die-cutting device to overcome the defects of the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A fabric substrate die-cutting device includes a fabric substrate unwinding roller, a bottom film unwinding roller, a first bonding roller assembly, a punching machine, a second bonding roller assembly, a product take-up roller, and a flame-spraying mechanism. The fabric substrate unwinding roller is used to unwind the fabric substrate; the bottom film unwinding roller is used to unwind the bottom film; the fabric substrate is located above the bottom film; the first and second bonding roller assemblies are sequentially arranged downstream of the fabric substrate unwinding roller and the bottom film unwinding roller, each including two symmetrically arranged bonding rollers that cooperate to bond the fabric substrate and the bottom film together; the punching machine is located between the first and second bonding roller assemblies and is used to punch-cut the fabric substrate; the product take-up rollers are all located downstream of the second bonding roller assembly and are used to take up the punched fabric substrate product; the flame-spraying mechanism is located between the second bonding roller assembly and the product take-up roller and is used to spray flame onto the punched fabric substrate product.

[0005] To optimize the above technical solution, the specific measures also include: Furthermore, the flame-spraying mechanism includes a flame-spraying device and a perforated part; the flame-spraying device is capable of spraying flame; the perforated part has a perforated structure composed of several through holes; the perforated structure is provided between the flame-spraying device and the punched fabric substrate product.

[0006] Furthermore, the hollowed-out component is a horizontally arranged hollowed-out cylinder; the flame-spraying device is fixed inside the hollowed-out cylinder; the cylinder wall below the flame-spraying device or the entire cylinder wall has the hollowed-out structure.

[0007] Furthermore, the perforated part is a horizontally arranged perforated plate; the flame-throwing device is fixed above the perforated plate.

[0008] Furthermore, the diameter of the through hole in the hollow structure is 1~3 mm, preferably 2 mm.

[0009] Furthermore, the distance between the perforated structure and the fabric substrate product is 1~3 mm, preferably 2 mm.

[0010] Furthermore, the bonding rollers in the first bonding roller assembly and the second bonding roller assembly are both composed of separate rollers disposed on both sides of the fabric substrate and the base film.

[0011] Furthermore, it also includes a waste material collection roller; the waste material collection roller is disposed between the second bonding roller assembly and the flame-spraying mechanism, and is used to collect the punched fabric substrate waste.

[0012] Furthermore, it also includes a barrier film unwinding roller; the barrier film unwinding roller is disposed between the waste material receiving roller and the product receiving roller, and is used to unwind the barrier film, which is located above the punched fabric substrate product.

[0013] Furthermore, it also includes a third bonding roller assembly; the third bonding roller assembly is disposed between the barrier film unwinding roller and the product take-up roller, and includes two bonding rollers arranged symmetrically above and below, the two bonding rollers cooperating with each other to bond the barrier film and the punched fabric substrate product together.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a fabric substrate die-cutting device that can effectively remove the burrs generated during the die-cutting of fabric substrate products. Specifically, this device uses a flame-spraying mechanism between the punching machine and the product take-up roller to burn off the burrs generated during die-cutting, thereby improving the quality of the fabric substrate product. The flame-spraying mechanism consists of a flame-spraying device and a perforated part with a hollow structure. The flame-spraying device sprays flames onto the die-cut fabric substrate product through the hollow structure, thereby controlling the flame size to precisely remove the burrs without damaging the fabric substrate product. Furthermore, the first and second bonding roller assemblies consist of two separate bonding rollers, which reduces the bonding area and compression between the fabric substrate and the base film, improving the burning effect on the burrs. This device also uses a barrier film unwinding roller and a third bonding roller assembly to cover the fabric substrate product after the burrs have been burned off with a barrier film, thereby preventing secondary friction and the regeneration of burrs during winding and stacking.

Detailed Implementation

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0017] like Figures 1-5 As shown, this utility model provides a fabric substrate A die-cutting device, including a fabric substrate unwinding roller 11, a bottom film unwinding roller 12, a first bonding roller assembly 2, a punching machine 3, a second bonding roller assembly 4, a product receiving roller 5, and a flame-spraying mechanism 6.

[0018] Fabric substrate unwinding roller 11 is used to unwind fabric substrate A. Bottom film unwinding roller 12 is used to unwind bottom film B. Fabric substrate A is located above bottom film B. First bonding roller assembly 2 and second bonding roller assembly 4 are sequentially arranged downstream of fabric substrate unwinding roller 11 and bottom film unwinding roller 12, each including two bonding rollers 21 arranged symmetrically, which cooperate to bond fabric substrate A and bottom film B together. Punching machine 3 is arranged between first bonding roller assembly 2 and second bonding roller assembly 4, and is used to punch and cut fabric substrate A. Product take-up rollers 5 are all arranged downstream of second bonding roller assembly 4, and are used to take up punched fabric substrate product C.

[0019] The flame-spraying mechanism 6 is located between the second bonding roller assembly 4 and the product receiving roller 5, and is used to spray flames onto the punched fabric substrate product C. By spraying flames onto the punched fabric substrate product C, the burrs and rough edges at the punched part of the fabric substrate A are burned off, such as... Figure 6 As shown.

[0020] In a preferred embodiment, the flame-spraying mechanism 6 includes a flame-spraying device and a perforated component. The flame-spraying device is capable of spraying flame. The flame-spraying device is an existing device such as a flame gun. The perforated component has a perforated structure composed of several through holes. The perforated structure is provided between the flame-spraying device and the punched fabric substrate product C, meaning the flame-spraying device sprays flame through the perforated structure onto the punched fabric substrate product C, thereby controlling the leakage of only a small flame to precisely burn off the burrs and roughness of the punched portion of the fabric substrate A.

[0021] In one specific embodiment, such as Figure 7 As shown, the perforated component is a horizontally arranged perforated cylinder 61. The flame-throwing device is fixed inside the perforated cylinder 61. The entire cylinder wall has a perforated structure. Of course, the perforated structure can also be made only in the cylinder wall below the flame-throwing device.

[0022] In another specific embodiment, such as Figure 8 As shown, the perforated part is a horizontally arranged perforated plate 62. The flamethrower is fixed above the perforated plate 62.

[0023] Specifically, the diameter of the through hole in the perforated structure is 1-3 mm, preferably 2 mm. The distance between the perforated structure and the fabric substrate product C is 1-3 mm, preferably 2 mm. Under these parameters, the flame-jet mechanism can precisely remove the burrs without damaging the fabric substrate product.

[0024] In a preferred embodiment, such as Figure 9 As shown, the bonding rollers 21 in the first bonding roller assembly 2 and the second bonding roller assembly 4 are both composed of split rollers 211 arranged on both sides of the fabric substrate A and the base film B. That is, the two upper split rollers 211 and the two lower split rollers 211 are symmetrically arranged, bonding the fabric substrate A and the base film B together on the left and right sides in the forward direction. By setting the bonding rollers 21 composed of split rollers 211, the bonding area and compression of the fabric substrate A and the base film B are minimized, so that when the flame-spraying mechanism 6 sprays flame onto the fabric substrate product C, the burrs are directly burned off, improving the burning effect.

[0025] like Figure 1 and Figure 4 As shown, the device also includes a waste collection roller 7. The waste collection roller 7 is disposed between the second bonding roller assembly 4 and the flame-spraying mechanism 6, and is used to collect the punched fabric substrate waste D.

[0026] In a preferred embodiment, such as Figure 1 and Figure 4As shown, the apparatus also includes a barrier film unwinding roller 8 and a third bonding roller assembly 9. The barrier film unwinding roller 8 is positioned between the waste material take-up roller 7 and the product take-up roller 5, and is used to unwind the barrier film E, which is located above the punched fabric substrate product C. The third bonding roller assembly 9 is positioned between the barrier film unwinding roller 8 and the product take-up roller 5, and includes two bonding rollers 21 arranged symmetrically above and below each other. The two bonding rollers 21 cooperate with each other to bond the barrier film E and the punched fabric substrate product C together. Applying the barrier film E to the fabric substrate product C after the burrs have been burned off can prevent secondary friction and the re-generation of burrs during winding and stacking.

[0027] During operation, the fabric substrate unwinding roller 11 and the bottom film unwinding roller 12 unwind the fabric substrate A and the bottom film B, respectively. The first bonding roller assembly 2 bonds the fabric substrate A and the bottom film B together and conveys them to the punching machine 3. The punching machine 3 punches the fabric substrate A, and it continues to be conveyed by the second bonding roller assembly 4. Then, the waste material collected by the waste material collection roller 7 separates the punched waste material from the punched fabric substrate product C, and the flame mechanism 6 burns off the burrs generated during punching. Finally, the release film E is applied to the fabric substrate product C by the release film unwinding roller 8 and the third bonding roller assembly 9, and the final product is then wound up by the product collection roller 5.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
