Description

Technical Field

[0001] This application relates to the technical field of paper roll production, and in particular to an auxiliary device for increasing the tensile force of a paper tape. Background Art

[0002] In the spinning process, paper rolls are required. The existing paper roll production process is to divide the base paper into several equal-width paper tapes according to different specifications and widths, and then lay the paper tapes layer by layer according to process requirements, apply glue, and send them to a reel winding machine for production.

[0003] During the process of applying glue to the paper tape, due to insufficient tensile force of the base paper, the glue on the surface of the paper tape is uneven, resulting in unstable quality of the finished product during the reel winding process. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, one of the purposes of this application is to provide an auxiliary device for increasing the tensile force of a paper tape, which has the advantage of being able to increase the tensile force of the paper tape.

[0005] The above object of this application is achieved through the following technical solutions:

[0006] An auxiliary device for increasing the tensile force of a paper tape includes a support frame, and a pneumatic component is provided on the support frame. The pneumatic component includes a driving member and pneumatic plates arranged oppositely. The paper tape passes between the two oppositely arranged pneumatic plates and is applied with pressure by the oppositely arranged pneumatic plates under the action of the driving member.

[0007] By adopting the above technical solution, during use, since the paper tape passes through between the two pneumatic plates, pressure is applied to the paper tape by the pneumatic plates, so that the tensile force of the paper tape can be increased, the uniformity and consistency of the paper tensile force can be improved, and the probability of poor glue application effect caused by the shaking of the paper tape due to external reasons can be reduced.

[0008] In a preferred example of this application, it can be further configured that: the pneumatic plate includes a pneumatic cavity and a deformation layer, the deformation layer covers the pneumatic cavity, the driving member is a gas source, and is connected to the pneumatic cavity for deforming the deformation layer.

[0009] By adopting the above technical solution, that is, during use, the deformation layer is deformed by air pressure, so that a good clamping effect can be achieved.

[0010] In a preferred example of this application, it can be further configured that: there are multiple pneumatic cavities and they are not connected to each other. The two oppositely arranged pneumatic plates are divided into an upper plate and a lower plate, and the pneumatic cavities working on the upper plate and the pneumatic cavities working on the lower plate are arranged alternately.

[0011] By adopting the above technical solution, the alternately arranged air pressure chambers cause the deformation layers of the upper plate and the lower plate to have spaced convex strips, making the paper tape form an S shape, and thus improving the clamping effect on the paper tape.

[0012] In a preferred example of the present application, it can be further configured that: a negative pressure chamber is further provided on the air pressure plate, and the negative pressure chamber and the air pressure chamber are arranged at intervals.

[0013] By adopting the above technical solution, the existence of the negative pressure chamber enables space to be provided for the corresponding deformation layer.

[0014] In a preferred example of the present application, it can be further configured that: an upper inclined surface is provided on the upper plate, the upper inclined surface is used to contact the paper tape, and a negative pressure hole is further provided on the upper plate, and the negative pressure hole is arranged on the upper inclined surface.

[0015] By adopting the above technical solution, the existence of the upper inclined surface makes the contact distance between the paper tape and the negative pressure hole smaller, and thus when the negative pressure hole sucks, it can have a good effect on removing the paper scraps remaining due to cutting on the paper tape.

[0016] In a preferred example of the present application, it can be further configured that: convex strips are further provided on the upper inclined surface, and the convex strips are used to contact the paper tape.

[0017] By adopting the above technical solution, the existence of the convex strips can reduce the friction between the paper tape and the upper inclined surface, and at the same time make the suction effect of the negative pressure hole better.

[0018] In a preferred example of the present application, it can be further configured that: air outlet holes are provided on the convex strips, and the air outlet holes are inclined.

[0019] By adopting the above technical solution, the existence of the air outlet holes can blow up the paper scraps attached to the paper tape and make them float towards the negative pressure chamber, so that under the suction of the negative pressure chamber, a better effect on removing the paper scraps can be achieved.

[0020] In a preferred example of the present application, it can be further configured that: obtain the specification of the paper tape, adjust the pressure in the air pressure chamber, and make the paper tape contact the convex strips.

[0021] By adopting the above technical solution, by adjusting the pressure for different specifications of paper tapes, the probability of damage to the paper tape caused during this process can be reduced.

[0022] In a preferred example of the present application, it can be further configured that: exhaust holes are further provided on at least one of the deformation layers, and the exhaust holes are arranged on both sides of the midline of the deformation layer.

[0023] By adopting the above technical solution, the presence of the exhaust holes enables further enhancement of the effect of removing paper scraps. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Referring to Figure 1 and Figure 2 , an auxiliary device for increasing the tensile force of a paper tape disclosed in the present application includes a support frame, and an air pressure assembly is provided on the support frame. The air pressure assembly includes an air pressure plate 1 and a driving member arranged oppositely. The paper tape passes between two oppositely arranged air pressure plates 1 and is applied with pressure by the oppositely arranged air pressure plates 1 under the action of the driving member.

[0029] The two oppositely arranged air pressure plates 1 are divided into an upper plate and a lower plate. An air pressure chamber 2 and a negative pressure chamber 3 are provided on the air pressure plate 1, and each air pressure chamber 2 is independently controlled. On the same air pressure plate 1, the air pressure chamber 2 and the negative pressure chamber 3 are arranged at intervals. The air pressure chamber 2 on the upper plate and the air pressure chamber 2 on the lower plate are arranged at intervals. A deformation layer 4 is further provided on the air pressure plate 1. In this embodiment, the deformation layer 4 is made of rubber material and is used to cover the air pressure chamber 2. In this embodiment, the driving member is a gas source, which is connected to the air pressure chamber 2 and is used to deform the deformation layer 4.

[0030] An upper inclined surface 5 is further provided on the upper plate. The upper inclined surface 5 is located on both sides of the negative pressure chamber 3. Ribs 8 are further provided on the upper inclined surface 5. The ribs 8 are located on the side of the upper inclined surface 5 close to the negative pressure chamber 3. An air outlet hole 81 is further provided on the side of the rib 8 close to the negative pressure chamber 3. The air outlet hole 81 is inclined and faces the paper tape. A negative pressure hole 7 is further provided on the upper plate. The negative pressure hole 7 is located on the side of the rib 8 away from the negative pressure chamber 3. The negative pressure chamber 3 and the negative pressure hole 7 are connected to an air extraction device, such as a vacuum pump. Each negative pressure chamber 3 and the negative pressure hole 7 can be independently controlled. The air outlet hole 81 is connected to the gas source. In this embodiment, the gas discharged from the air outlet hole 81 is the gas generated by an example blower.

[0031] A lower inclined surface 6 is further provided on the lower plate. The lower inclined surface 6 does not contact the paper tape.

[0032] An exhaust hole 41 is further provided on the deformation layer 4. The exhaust hole 41 is arranged on both sides of the midline of the deformation layer 4 and is not covered by the paper tape. In use, the first deformation layer 4 and the last deformation layer 4 may not be provided with the exhaust hole 41.

[0033] During production, obtain the specifications of the paper tape, such as parameters like thickness, weight, and width, and adjust the pressure in the air pressure chamber 2 so that the convex strips 8 of the deformation layer 4 are formed, and the paper tape is moved upward until it contacts the convex strips 8.

[0034] The implementation principle of this embodiment is that the paper tape is deformed through the deformation layer 4, thereby realizing the clamping of the paper tape. Therefore, the uniformity and consistency of the paper tape tension can be improved, and the probability of poor glue application effect caused by the shaking of the paper tape due to external reasons can be reduced.
