[0030] Example

[0031] like Figure 2 one Figure 5 As shown, this embodiment provides a detour die-cutting device, including a die-cutting mechanism 1, a driving mechanism 5, and a pressing mechanism 6. The die-cutting mechanism 1 has a first die 2 and a second die 3 arranged in parallel, and the first die 2 and the second die 3 are located in the same die-cutting sleeve 4. The material travels through the first die 2 first, and then through the first guide mechanism 14, the second guide mechanism 15, the third guide mechanism 22, and the fourth guide mechanism 23 to form a detour material guiding structure, forming a vertical upward bend to form an arc-like shape, returning to a position close to the first die 2, and being misaligned relative to the position of the first die 2 on the horizontal plane. Under the drive of the driving mechanism 5, the material travels through the first die 2 and the second die 3 in the same direction, forming a detour material travel path. Then, the pressing mechanism 6 presses and discharges the material before and after the die-cutting process.

[0032] The die-cutting mechanism 1 is disposed between the unwinding mechanism 16 and the winding mechanism 17 along a first direction. The die-cutting mechanism 1 has a first die 2 and a second die 3. The first die 2 is disposed at a first die-cutting station, and the second die 3 is disposed at a second die-cutting station. The first die-cutting station and the second die-cutting station are arranged sequentially along a second direction to form the same die-cutting sleeve 4. The four guiding mechanisms are configured as a detour material guiding structure. The detour material guiding structure is used to guide the blank material unwound from the unwinding mechanism 16 into the die-cutting mechanism 1 twice, and pass through the first die-cutting station and the second die-cutting station respectively, and then be wound into the winding mechanism 17. The second direction and the first direction intersect.

[0033] The four guide mechanisms include a first guide mechanism 14, a second guide mechanism 15, a third guide mechanism 22 and a fourth guide mechanism 23. The first guide mechanism 14, the winding mechanism 17 and the second guide mechanism 15 are located on the same side of the die-cutting mechanism 1 and are sequentially and spaced apart along the second direction. The unwinding mechanism 16, the fourth guide mechanism 23 and the third guide mechanism 22 are located on the same side of the die-cutting mechanism 1 and are sequentially and spaced apart along the second direction.

[0034] The first guide mechanism 14 and the unwinding mechanism 16 form a first material conveying track 19. The second guide mechanism 15 and the third guide mechanism 22 form a second material conveying track 24. The fourth guide mechanism 23 and the winding mechanism 17 form a third material conveying track 25. The second material conveying track 24 is spaced apart between the first material conveying track 19 and the third material conveying track 25 along the second direction. The first work station is located on the first material conveying track 19. The second work station is located on the third material conveying track 25.

[0035] The second guide mechanism 15 and the third guide mechanism 22 are arranged above the pressing mechanism 6 to better receive the material in the shape of a similar circular arc formed by the first die 2, the vertical upward bending and the downward bending in the same direction through the second die 3. The guide mechanisms are arranged in parallel along the material conveying route. The first guide mechanism 14, the second guide mechanism 15, the third guide mechanism 22 and the fourth guide mechanism 23 each include a plurality of guide rods arranged in parallel along the material conveying route. The plurality of guide rods arranged in parallel along the material conveying route ensures that the material does not deviate from the given conveying route during the conveying process, thereby causing the die-cutting deviation and affecting the final die-cutting precision.

[0036] The first die 2 includes a first cutting edge 10 arranged in parallel along the material conveying route. The second die 3 includes a second cutting edge. The die-cutting mechanism 1 further includes a cutting die. The cutting die moves along the vertical direction and approaches or moves away from the die-cutting nest 4. When the cutting die approaches the limit position of the die-cutting nest 4, the cutting die simultaneously presses the first die 2 and the second die 3. The material is die-cut by the pressing of the first cutting edge 10 and the second cutting edge and the cutting die.

[0037] The die-cutting mechanism 1 further includes a plurality of positioning columns 11 arranged along the material conveying route at the second die 3 and arranged on both sides of the material conveying route. When the material travels along the conveying route, the two rows of positioning columns 11 arranged in parallel can ensure that the material does not deviate from the conveying route during the conveying process and ensure that the material does not deviate when the cutting die presses the second die 3.

[0038] The die-cutting mechanism 1 further comprises a plurality of knife lines 12 arranged along the material running route at the first die 2 and on both sides of the material running route, which are used to cut the material passing through the first die 2 to cut out the material width required for subsequent processing, so as to ensure that the material can be better processed when it runs to the position of the second die 3. When the knife lines 12 cut the material, the material still in the running route will not change the running route due to the limitation between the two rows of knife lines 12. However, the material cut down by the knife lines 12 will bend away from the running direction on both sides during the running process due to the loss of support and the obstruction of the knife lines 12 in the running route of the cut-down material, and will fall down under the action of gravity and continuously run, so as to finally discharge the material cut down by the knife lines 12.

[0039] The driving mechanism 5 comprises a driving roller 13 arranged on the die-cutting mechanism 1, specifically arranged on the side of the first die 2 and the second die 3 in parallel, which simultaneously receives the material passing through the first die 2 and the second die 3 arranged in parallel and drives the material to run along the given running route.

[0040] The material pressing mechanism 6 comprises a first material pressing unit 7 and a second material pressing unit 8. The first material pressing unit 7 is arranged on the feeding side of the first die 2 and the second die 3 and is used at least for pressing the material. The second material pressing unit 8 is arranged on the discharging side of the first die 2 and the second die 3 and is used at least for pressing the material and discharging the waste. Specifically, the first material pressing unit 7 and the second material pressing unit 8 comprise a plurality of pressing plates 9 arranged in parallel along the running route of the material, but the first material pressing unit 7 and the second material pressing unit 8 are different in specific action. The plurality of pressing plates 9 of the first material pressing unit 7 are arranged in parallel along the running route of the material, and the pressing plates 9 press the material in the running route, which is used to extrude the material before it passes through the first die 2 or the second die 3, so that the material passing through the first die 2 or the second die 3 for die-cutting is flat, which is convenient for die-cutting. The end face of the pressing plate 9 of the second material pressing unit 8 close to the first die 2 and the second die 3 has an inclined angle, and the end face faces the running direction of the material, and the pressing plate 9 presses the material in the running route, which is used to scrape the excess waste 20 on the material output from the first die 2 or the second die 3. When the pressing plate 9 scrapes the material, it will apply downward pressure and lateral extrusion force to the material. During the scraping process, the upper half of the material will move outward, while the lower half will not move due to the connection with the original material. The waste 20 separated from the original material will bend, and after leaving the pressing plate 9, the bent part of the material will no longer be stressed and can maintain deformation, thereby forming a roll shape.

[0041] It should be noted that the first pressing unit 7 is located between the pressing plate 9 on the discharge side of the first die 2 and the extruded material, and a cover film 21 is arranged between them. The cover film 21 is in the form of a roll, and one end of the cover film 21 is clamped between the pressing plate 9 and the material. After the material is scraped off the waste 20, the material output from the discharge side of the first die 2 will rub against the cover film 21 accumulated between it and the pressing plate 9, and will be tightly attached to the cover film 21 under the extrusion of the pressing plate 9, and will continuously adhere to the surface of the material under the movement of the material.

[0042] The detour die cutting device also includes a unwinding mechanism 16, which includes but is not limited to a unwinding roller. Any mechanism that can wind and contain the material before die cutting can be considered as the protection object of the present application. The unwinding mechanism 16 provides material to the material pressing mechanism 6 on the side perpendicular to the parallel direction of the first die 2 and the second die 3. In other words, the material roll before entering the travel route is set on the unwinding mechanism 16, and the material is continuously fed to the starting end of the travel route to perform material feeding and die cutting in the detour route.

[0043] The detour die cutting device also includes a winding mechanism 17, which includes but is not limited to a winding roller. Any mechanism that can wind and contain the material after die cutting can be considered as the protection object of the present application. The winding mechanism 17 receives the material output by the material pressing mechanism 6 on the other side perpendicular to the parallel direction of the first die 2 and the second die 3. In other words, the material roll after passing through the travel route and after die cutting is set on the winding mechanism 17 to realize the storage of the material after die cutting.

[0044] It should be understood that the above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit and essence of the present application should be covered within the protection scope of the present application.
