Description

Technical Field

[0001] This application belongs to the technical field of packaging machinery, and particularly relates to a window opening and peeling device for composite substrates. Background Art

[0002] In the process of manufacturing plaster patches or dressing patches, especially in scenarios where a specific window structure needs to be formed on a substrate and the release paper is peeled off to partially expose the adhesive layer on the substrate so that the drug can be adhered to the exposed adhesive layer position. For a long time, it mainly relied on manual operation. This method of manually opening the window and peeling off the release paper is not only time-consuming and laborious, but also easily affected by human factors such as operation proficiency and fatigue degree, resulting in inconsistent peeling effects. It may even damage the substrate or the release paper, affecting the quality of the final product. In addition, with the expansion of production scale and the improvement of processing requirements, the method of manually peeling off the release paper has been difficult to meet the requirements of efficient and stable production. Therefore, it is necessary to solve the above technical problems. Summary of the Invention

[0003] The purpose of the embodiments of this application is to provide a window opening and peeling device for composite substrates to solve the technical problem of low efficiency of window opening and peeling of composite substrates in the prior art.

[0004] To achieve the above purpose, the technical solution adopted in this application is: to provide a window opening and peeling device for composite substrates, including:

[0005] A pay-off reel for unreeling the composite substrate;

[0006] A traction roller group, arranged at an interval from the pay-off reel and used for traction of the composite substrate;

[0007] A rotary cutting assembly, arranged between the pay-off reel and the traction roller group and including a knife roller and a pressure roller that are parallel to each other. The knife roller cooperates with the pressure roller to form a passage for the composite substrate to pass through and can rotary cut the release paper in the composite substrate into a preset shape;

[0008] A peeling assembly, arranged between the rotary cutting assembly and the traction roller group and including a peeling block, and a leading roller and a trailing roller arranged on both sides of the peeling block. The peeling block has a front peeling surface and a rear peeling surface that are adjacent and arranged at an acute angle. The intersection of the front peeling surface and the rear peeling surface is used to convey the composite substrate between the leading roller and the trailing roller and can make the composite substrate form an acute-angle fold before and after passing through the peeling block.

[0009] Optionally, the included angle B formed between the front peeling surface and the rear peeling surface is less than 90°.

[0010] Optionally, the peeling assembly further includes a chute disposed between the peeling block and the traction roller set, and a waste guide plate connecting the peeling block and the chute;

[0011] One side of the waste guide plate close to the peeling block does not exceed the front peeling surface in the vertical direction and is higher than the side of the waste guide plate close to the chute.

[0012] Optionally, the peeling assembly further includes a waste blocking plate disposed at an interval from the peeling block and parallel to the waste guide plate;

[0013] At least a part of the waste blocking plate overlaps with the front peeling surface in the normal direction of the front peeling surface.

[0014] Optionally, a plurality of intermediate guide rollers are further disposed between the unwinding shaft and the traction roller set.

[0015] The beneficial effects of the composite substrate window peeling device provided by this application are as follows: Compared with the prior art, in the composite substrate window peeling device provided by this application, there is a rolling cutting assembly for rolling and cutting the release paper in the composite substrate into a preset shape, and a peeling assembly for peeling the release paper in the window part from the adhesive bottom layer of the composite substrate. Among them, the front guide roller can cooperate with the rear guide roller to convey the composite substrate with the window already rolled and cut to the intersection of the front peeling surface and the rear peeling surface of the peeling block. Since the front peeling surface and the rear peeling surface are arranged at an acute angle and the composite substrate can form an acute-angle fold before and after passing through the peeling block, the release paper in the window part of the composite substrate can be separated from the adhesive bottom layer of the composite substrate at the intersection of the front peeling surface and the rear peeling surface, so that the window peeling efficiency of the composite substrate can be significantly improved, far superior to the prior art.

[0026] Please refer to Figures 1 to 4 together, and a windowing and peeling device for a composite substrate provided by an embodiment of the present application will now be described. This windowing and peeling device for a composite substrate includes an unwind reel 100, a traction roller group 200, a rotary cutting assembly 300, and a peeling assembly 400. Among them:

[0027] The unwinding reel 100 is used for unwinding the composite substrate 1000; the traction roller group 200 is arranged at an interval from the unwinding reel 100 and is used for pulling the composite substrate 1000; the rotary cutting assembly 300 is arranged between the unwinding reel 100 and the traction roller group 200 and includes a cutter roller 301 and a pressure-bearing roller 302 that are parallel to each other. The cutter roller 301 cooperates with the pressure-bearing roller 302 to form a passage for the composite substrate 1000 to pass through and can rotary cut the release paper 1001 in the composite substrate 1000 into a preset shape; the peeling assembly 400 is arranged between the rotary cutting assembly 300 and the traction roller group 200 and includes a peeling block 401, a leading roller 402 and a trailing roller 403 arranged on both sides of the peeling block 401. The peeling block 401 has a front peeling surface 411 and a rear peeling surface 412 that are adjacent and arranged at an acute angle. The intersection of the front peeling surface 411 and the rear peeling surface 412 is used for conveying the composite substrate 1000 between the leading roller 402 and the trailing roller 403 and can cause the composite substrate 1000 to form an acute-angle fold before and after passing through the peeling block 401.

[0028] According to the above structure provided in this embodiment, in the composite substrate window peeling device provided in this embodiment, a rotary cutting assembly 300 for rotary cutting the release paper 1001 in the composite substrate 1000 into a preset shape is provided, and a peeling assembly 400 for peeling the release paper 1001 in the window part from the adhesive bottom layer 1002 of the composite substrate 1000 is also provided. Among them, the leading roller 402 can cooperate with the trailing roller 403 to convey the composite substrate 1000 with the window already rotary cut to the intersection of the front peeling surface 411 and the rear peeling surface 412 on the peeling block 401. Since the front peeling surface 411 and the rear peeling surface 412 are arranged at an acute angle and the composite substrate 1000 can form an acute-angle fold before and after passing through the peeling block 401, the release paper 1001 in the window part on the composite substrate 1000 can be separated from the adhesive bottom layer 1002 of the composite substrate 1000 at the intersection of the front peeling surface 411 and the rear peeling surface 412. In this way, the window peeling efficiency of the composite substrate 1000 can be significantly improved, far better than the prior art.

[0029] In another embodiment of the present application, please refer to Figures 1 to 4 together. The included angle B formed between the front peeling surface 411 and the rear peeling surface 412 is less than 90°, and it is preferably 78° in this embodiment. According to the above structure provided in this embodiment, the peeling block 401 with the above included angle for the front peeling surface 411 and the rear peeling surface 412 can achieve a better peeling effect.

[0030] In another embodiment of the present application, please refer to Figures 1 to 4, the stripping assembly 400 further includes a chute 404 disposed between the stripping block 401 and the traction roller set 200, and a waste guide plate 405 connected between the stripping block 401 and the chute 404. One side of the waste guide plate 405 close to the stripping block 401 does not exceed the front stripping surface 411 in the vertical direction and is higher than the side of the waste guide plate 405 close to the chute 404. According to the above structure provided in this embodiment, the release paper 1001 stripped by the stripping block 401 can enter the chute 404 through the guidance of the waste guide plate 405, which is beneficial to the waste collection of the release paper 1001.

[0031] In another embodiment of the present application, please also refer to Figures 1 to 4 , the stripping assembly 400 further includes a waste blocking plate 406 disposed at an interval from the stripping block 401 and parallel to the waste guide plate 405. At least a part of the waste blocking plate 406 overlaps with the front stripping surface 411 in the normal direction of the front stripping surface 411. According to the above structure provided in this embodiment, the release paper 1001 stripped when the composite substrate 1000 passes through the intersection of the front stripping surface 411 and the rear stripping surface 412 can be blocked by the waste blocking plate 406 and smoothly pass between the waste blocking plate 406 and the waste guide plate 405 and enter the chute 404, which is beneficial to making the waste collection effect of the release paper 1001 better.

[0032] In another embodiment of the present application, please also refer to Figures 1 to 4 , a plurality of intermediate guide rollers 500 are further disposed between the unwinding reel 100 and the traction roller set 200. According to the above structure provided in this embodiment, the intermediate guide rollers 500 can make the conveying process of the composite substrate 1000 more stable, which is beneficial to further improving the window stripping efficiency of the composite substrate 1000.

[0033] The above are only the preferred embodiments of the present application and are not intended to limit the present application.
