Technical Field

[0001] The utility model relates to the technical field of die cutting, in particular to an adjustable pressing roller. Background Art

[0002] At present, when die-cutting thick materials with soft colloid, the roller of the machine will press on the surface of the product, causing the adhesive to be squeezed and deformed, making waste removal difficult and increasing the defective rate.

[0003] In order to solve the problem, the utility model discloses an adjustable pressing roller. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model discloses an adjustable pressing roller.

[0005] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: an adjustable pressure roller, including a rubber roller for cooperating with a bottom roller, an air bag is arranged inside the rubber roller, and at least two ejection components that can pass through the bottom of the rubber roller are connected to the air bag, and at least two circular sleeves are arranged on the outside of the rubber roller, which are respectively connected to at least two ejection components.

[0006] Further preferably, the airbag is provided with an air nozzle, and the rubber roller is provided with a through hole for allowing the air nozzle to leak out.

[0007] Further preferably, the ejection assembly comprises two ejection brackets, and the rubber roller is provided with two through slots for the ejection brackets to pass through.

[0008] Further preferably, a surface of the ejection bracket in contact with the circular sleeve is an arc-shaped structure adapted to the circular sleeve.

[0009] Further preferably, the circular sleeve is made of rubber material.

[0010] The utility model achieves the following beneficial effects:

[0011] When the adjustable pressure roller provided by the utility model is used in conjunction with the bottom roller, the air bag can be inflated to lift the bottom roller upward as a whole, thereby ensuring that the pressure roller will not cause the thick and soft colloid material to overflow and deform. Compared with the prior art, the utility model has stronger practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0019] Example

[0020] Example

[0021] In order to solve the problem in the prior art that when die-cutting thick and soft colloid materials, the roller of the machine will press on the surface of the product, causing the back glue to be squeezed and deformed and difficult to discharge waste,

[0022] refer to Figure 1-Figure 3 As shown, the utility model provides an adjustable pressure roller, including a rubber roller 10 for cooperating with a bottom roller 20, an airbag 30 is arranged inside the rubber roller 10, and at least two ejection components 40 that can pass through the bottom of the rubber roller 10 are connected to the airbag 30, and at least two circular sleeves 50 are respectively connected to the at least two ejection components 40 on the outside of the rubber roller 10. Specifically, the circular sleeves 50 in the present application are made of rubber material. During specific use, the airbag 30 can be lifted upward as a whole by inflating it, so that it can be ensured that the pressure roller will not cause the material with thick thickness and soft colloid to overflow and deform. Compared with the prior art, it has stronger practicality.

[0023] In one specific embodiment, the airbag 30 is provided with an air nozzle 31 , and the rubber roller 10 is provided with a through hole (not shown) for allowing the air nozzle 31 to leak out, so that the airbag 30 can be controlled to be inflated or deflated.

[0024] In one embodiment, the ejection assembly 40 includes two ejection brackets 41, and the side of the ejection bracket 41 that contacts the circular sleeve 50 is an arc-shaped structure that matches the circular sleeve 50. The rubber roller 10 is provided with two through grooves 11 for the ejection brackets 41 to pass through. When the airbag 30 is inflated, the two ejection brackets 41 will pass through the two through grooves 11 and prop up the circular sleeve 50.

[0025] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
