Description

Technical Field

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

[0002] In the spinning process, paper rolls are needed. The existing paper roll production process is to divide the base paper into several equal paper strips according to different specifications and widths, and then lay the paper strips layer by layer according to the process requirements, and then glue them to the tube winding machine for production.

[0003] During the gluing process of the paper tape, insufficient tension on the base paper causes uneven glue on the surface of the paper tape, resulting in unstable quality of the finished product during the tube rolling process. Summary of the Invention

[0004] In view of the deficiencies in the prior art, one of the purposes of this application is to provide an auxiliary device for increasing the tension of a paper tape, which has the advantage of being able to increase the tension of a paper tape.

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

[0006] An auxiliary device for increasing the tension of a paper tape comprises a support frame provided with a pneumatic assembly, wherein the pneumatic assembly comprises a driving member and oppositely arranged pneumatic plates. The paper tape passes between the two oppositely arranged pneumatic plates and is subjected to 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 between the two air pressure plates, pressure is applied to the paper tape through the air pressure plates, thereby increasing the tension of the paper tape, improving the uniformity and consistency of the paper tension, and reducing the probability of poor gluing effect caused by paper tape shaking due to external reasons.

[0008] In a preferred example, the present application can be further configured as follows: the pneumatic plate includes a pneumatic cavity and a deformation layer, the deformation layer covers the pneumatic cavity, and the driving member is an air source, which is connected to the pneumatic cavity and is used to deform the deformation layer.

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

[0010] In a preferred example, the present application can be further configured as follows: there are multiple air pressure chambers that are not interconnected, and the two relatively arranged air pressure plates are divided into an upper plate and a lower plate, and the air pressure chambers working on the upper plate and the air pressure chambers working on the lower plate are staggered.

[0011] By adopting the above technical solution, the staggered air pressure chambers enable the deformation layers of the upper plate and the lower plate to be separated by convex strips, so that the paper tape forms an S shape, thereby achieving a better clamping effect on the paper tape.

[0012] In a preferred example, the present application can be further configured as follows: a negative pressure cavity is further provided on the air pressure plate, and the negative pressure cavity and the air pressure cavity are spaced apart.

[0013] By adopting the above technical solution, the presence of the negative pressure cavity can provide space for the corresponding deformation layer.

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

[0015] By adopting the above technical solution, the presence of the upper inclined surface makes the contact distance between the paper tape and the negative pressure hole smaller, so that the negative pressure hole can effectively remove the paper scraps left on the paper tape due to cutting during suction.

[0016] In a preferred example, the present application can be further configured as follows: a convex strip is further provided on the upper inclined surface, and the convex strip is used to contact the paper tape.

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

[0018] In a preferred example, the present application can be further configured as follows: the convex strip is provided with an air outlet, and the air outlet is arranged obliquely.

[0019] By adopting the above technical solution, the presence of the air outlet makes it possible to blow up the paper scraps attached to the paper tape and float them into the negative pressure chamber, thereby achieving a better removal effect on the paper scraps under the suction action of the negative pressure chamber.

[0020] In a preferred example, the present application can be further configured as follows: obtaining the specifications of the paper tape, and adjusting the pressure in the air pressure chamber so that the paper tape and the convex strips are in contact.

[0021] By adopting the above technical solution and adjusting the pressure of paper tapes of different specifications, the probability of paper tape damage caused in the process can be reduced.

[0022] In a preferred example, the present application can be further configured as follows: at least one of the deformable layers is provided with exhaust holes, and the exhaust holes are arranged on both sides of the center line of the deformable layer.

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

[0028] Reference Figure 1 and Figure 2 , an auxiliary device for increasing the tension of a paper tape disclosed in this application, includes a support frame, on which a pneumatic assembly is provided, the pneumatic assembly includes relatively arranged pneumatic plates 1 and a driving member, and the paper tape passes between the two relatively arranged pneumatic plates 1 and is exerted with pressure by the relatively arranged pneumatic plates 1 under the action of the driving member.

[0029] Two opposing pneumatic plates 1 are divided into an upper plate and a lower plate. Each plate is equipped with a pneumatic chamber 2 and a negative pressure chamber 3, each of which is independently controlled. Within the same plate, the pneumatic chambers 2 and negative pressure chambers 3 are spaced apart, with the pneumatic chambers 2 on the upper plate and 2 on the lower plate spaced apart. The plate is also equipped with a deformable layer 4. In this embodiment, the deformable layer 4 is made of rubber and covers the pneumatic chambers 2. In this embodiment, the driving element is an air source, which is connected to the pneumatic chambers 2 and is used to deform the deformable layer 4.

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

[0031] A lower inclined surface 6 is also provided on the lower plate, and the lower inclined surface 6 does not contact the paper tape.

[0032] The deformable layer 4 is further provided with vent holes 41, which are arranged on both sides of the center line of the deformable layer 4 and are not covered by the paper tape. In use, the first deformable layer 4 and the last deformable layer 4 may not be provided with vent holes 41.

[0033] During production, the specifications of the paper tape, such as thickness, weight and width, are obtained, and the pressure in the air pressure chamber 2 is adjusted to make the deformable layer 4 bulge and move the paper tape upward until it contacts the convex strip 8.

[0034] The implementation principle of this embodiment is: the paper tape is deformed by the deformation layer 4, thereby achieving clamping of the paper tape, thereby improving the uniformity and consistency of the paper pulling force and reducing the probability of poor gluing effect caused by paper tape shaking due to external reasons.
