Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, and specifically discloses a circular die-cutting air waste removal device. Background Technology

[0002] For waste removal from small holes in die-cutting circular knives, existing technologies all involve adding a bottom film for waste removal. However, for products with special structures, the waste removal requires removing two layers of material from the bottom film. Since both layers are release surfaces without any adhesive, only one layer of waste material can be removed during waste removal, while the other layer falls into the middle of the product, rendering the entire product unusable.

[0003] To address this problem, this application discloses an aerial waste removal device for circular die cutting. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model discloses an aerial waste discharge device for circular die cutting.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a circular die-cutting air waste discharge device, including a die-cutting circular blade, an OPP tape feeding roller, and a receiving roller. The outer circumference of the die-cutting circular blade is provided with several die-cutting holes, the interior of the die-cutting holes is filled with foam, and silicone is attached to the bottom surface of the foam. The OPP tape feeding roller and the receiving roller are suspended above the die-cutting circular blade, and the OPP tape released by the OPP tape feeding roller is collected by the receiving roller through the upper surface of the die-cutting circular blade.

[0006] A further preferred embodiment is that the foam is positioned above the die-cutting holes on the outer periphery of the die-cutting circular blade.

[0007] A further preferred embodiment is that several die-cutting holes are formed in a linear array on the die-cutting circular blade.

[0008] More preferably, an auxiliary pressure bar is provided on each of the two upper sides of the die-cutting circular blade, and the OPP tape released by the OPP tape feeding roller is pressed by the two auxiliary pressure bars over the upper surface of the die-cutting circular blade.

[0009] A further preferred embodiment is that two auxiliary pressure bars press down on one-third of the OPP tape covering the die-cutting circular blade.

[0010] More preferably, the OPP tape released by the OPP tape feeding roller is in the opposite direction to the material being cut by the die-cutting circular knife.

[0011] This utility model achieves the following beneficial effects:

[0012] The waste removal device provided in this application can remove waste from both the top and bottom layers of two-layer release film once each, achieving 100% removal of waste. For a single layer of small-hole waste, the bottom film only serves as a pad, eliminating the need for waste removal. In this way, the bottom film can be recycled multiple times, saving on bottom film, reducing the company's production costs, and demonstrating high practical value.

[0013] Other features and advantages of this invention will be set forth in the following description and will be apparent in part from the description, or may be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0020] Example

[0021] To address the issue of waste removal from 10 small holes in existing die-cutting circular knives, which typically involves adding a base film for waste removal, but suffers from problems with special product structures where two layers of material need to be removed (both layers are non-adhesive at the release surface), only one layer can be removed during waste removal, leaving the other layer stuck in the middle of the product and rendering the entire sheet unusable. (Refer to...) Figure 1 and Figure 2 As shown, this application discloses a circular die-cutting air waste discharge device, including a die-cutting circular blade 10, an OPP tape feeding roller 20, and a receiving roller 30. The outer circumference of the die-cutting circular blade 10 is provided with a number of die-cutting holes 11. Preferably, the number of die-cutting holes 11 are arranged in a linear array on the die-cutting circular blade 10. The inside of the die-cutting holes 11 is filled with foam 12, and silicone 13 is attached to the bottom surface of the foam 12. The OPP tape feeding roller 20 and the receiving roller 30 are suspended above the die-cutting circular blade 10, and the OPP tape released by the OPP tape feeding roller 20 is collected by the receiving roller 30 through the upper surface of the die-cutting circular blade 10.

[0022] In the first embodiment, the lower waste is a double-layer material without adhesive in the middle. The die-cutting round blade 10 cuts the strip. During this process, the bottom film discharges the lower waste, while the upper small hole waste is brought to the surface of the mold hole and fixed by the silicone 13. Finally, it is carried away by the OPP tape released by the OPP tape feeding roller 20. In this way, waste is discharged once from the top and once from the bottom.

[0023] In the second embodiment, the waste material is a single layer. The die-cutting round blade 10 cuts the strip. During this process, the bottom support film only serves as a backing for the blade. The waste material with small holes is brought to the surface of the small holes in the mold and fixed by the silicone 13. Finally, it is carried away by the OPP tape released by the OPP tape feeding roller 20. In this way, the waste material with single-layer small holes is discharged.

[0024] In order to ensure that the waste material generated by the die-cutting circular blade 10 can be adhered to the silicone 13, the foam 12 of this application is set to be higher than the die-cutting hole 11 on the outer periphery of the die-cutting circular blade 10. Since the silicone 13 of this application is fixed to the bottom surface of the foam 12, the silicone 13 of this application is also located outside the die-cutting hole 11.

[0025] In addition to the above structure, this application also provides an auxiliary pressure bar 40 on each of the two sides above the die-cutting circular blade 10. The OPP tape released by the OPP tape feeding roller 20 is pressed by the two auxiliary pressure bars 40 over the upper surface of the die-cutting circular blade 10, and the two auxiliary pressure bars 40 press the OPP tape to cover one-third of the die-cutting circular blade 10. Based on this setting, it can be ensured that the OPP tape can stick to the small hole waste material adhering to the surface of the silicone 13. In this way, the OPP tape can completely remove the small hole waste material.

[0026] Of course, the OPP tape released by the OPP tape feeding roller 20 in this application has the opposite feeding direction to the material being cut by the die-cutting circular knife 10. In addition, it is understood that the adhesive side of the OPP tape in this application should be set downwards.

They should not be construed as limiting the scope of protection of this utility model.
