Description

Technical Field

[0001] The utility model relates to the technical field of papermaking, and particularly relates to a paper towel winding device with adjustable tension Background Art

[0002] Paper towels are daily necessities with various types. Most of them are produced from renewable resources such as wood pulp. When in use, paper towels can replace towels, etc., providing a one-time use for cleaning wiped objects, which is more hygienic and cleaner than towels. After production, the paper towels are in a long strip shape and need to be wound by a winding device. The winding device is provided with a paper tube, and there is an adhesive on the paper tube. Thus, one end of the long strip-shaped paper towel after production can be adhered to the paper tube, and the paper towel is wound outside the paper tube by rotating the winding device, thereby batch-winding the produced paper towels. The winding speed is fast, and the wound paper towels are more convenient for transportation.

[0003] Although the above-mentioned prior art can solve corresponding technical problems, there are still certain defects: the existing paper towel winding device fixes the paper tube by expanding the winding cylinder, and then winds the paper towel. It cannot quickly adjust the tension. Therefore, a paper tube must be used to isolate the paper towel from the winding cylinder, otherwise it is easy to cause damage to the winding cylinder. And the paper tube is a one-time item, and one paper tube is consumed for each roll of paper towel wound, which invisibly increases the production cost of paper towels. At the same time, the glue smeared on the inner wall of the paper tube adheres to the innermost layer of the paper towel, making it difficult to peel off the innermost layer of the paper towel from the paper tube, resulting in waste. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a paper towel winding device with adjustable tension, which is low in cost and less waste, aiming at the defects and deficiencies of the prior art.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions: a paper towel winding device with adjustable tension, including a base and a rotating shaft movably clamped on the base. A power motor fixedly connected to the base is provided at the end of the rotating shaft. A winding cylinder is detachably provided in the middle section of the rotating shaft. The winding cylinder includes a connecting tube and an expansion airbag arranged in the connecting tube. Outer convex blocks are provided on the outer wall of the expansion airbag. A silica gel tube is detachably provided outside the outer convex blocks. A one-way valve tube penetrating the silica gel tube and the outer convex blocks is provided on the expansion airbag. The expansion airbag is inflated and deflated through the one-way valve tube, so that the silica gel tube expands and contracts to attach to and wind the paper towel.

[0006] Further improvement is that: a lifting bracket is further provided between the base and the rotating shaft.

[0007] Further improvement is that: the outer convex block is of an arc-shaped block structure, and its outer surface is provided with a frosted layer.

[0008] Further improvement: The silica gel tube includes a silica gel inner tube detachably arranged outside the outer convex block and a silica gel outer tube arranged outside the silica gel inner tube. The silica gel inner tube and the silica gel outer tube are penetrated with tracheal grooves.

[0009] Further improvement: A plurality of friction bumps are arranged on the outer wall of the silica gel outer tube.

[0010] Further improvement: A plurality of suction and pressure frames are further arranged between the outer wall of the silica gel inner tube and the inner wall of the silica gel outer tube.

[0011] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: The present utility model uses a silica gel tube with a very rough surface and certain self - adhesiveness to contact the paper towel. When winding, the expansion airbag is inflated to expand the silica gel tube, so that it can act as a paper tube to wind the paper towel. After winding, the expansion airbag is deflated to make the silica gel tube contract, so that the connection between the wound paper towel and the silica gel tube is lost, and thus the paper towel can be quickly taken out. During the use process, glue and a paper tube are not required, the winding cost is lower, and the contact between the inner - layer paper towel and the glue is avoided, and less paper towel is wasted.

[0017] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0018] Refer to Figures 1-4As shown in the figure, the technical solution adopted in this specific embodiment is as follows: An adjustable-tension paper towel winding device includes a base 1 and a rotating shaft 2 movably engaged with the base 1. A power motor 4 fixedly connected to the base 1 is provided at the end of the rotating shaft 2. A winding cylinder 3 is detachably provided in the middle section of the rotating shaft 2. The winding cylinder 3 includes a connecting tube 31 and an expansion airbag 32 arranged in the connecting tube 31. Outer convex blocks 33 are provided on the outer wall of the expansion airbag 32. A silica gel tube 34 is detachably provided outside the outer convex blocks 33. The silica gel tube 34 includes a silica gel inner tube 341 detachably provided outside the outer convex blocks 33 and a silica gel outer tube 342 arranged outside the silica gel inner tube 341. Air tube grooves 344 are penetrated through the silica gel inner tube 341 and the silica gel outer tube 342. A one-way valve tube 35 penetrating the silica gel tube 34 and the outer convex blocks 33 is provided on the expansion airbag 32. The expansion airbag 32 is inflated and deflated through the one-way valve tube 35, so that the silica gel tube 34 expands and contracts to attach to and wind the paper towel. During use, the paper towel is pulled to the surface of the silica gel outer tube 342, and the paper towel is squeezed so that the paper towel adheres to the silica gel outer tube 342. Subsequently, the expansion airbag 32 is inflated through the one-way valve tube 35, so that the expansion airbag 32 expands and pushes the outer convex blocks 33 outwards, causing the outer convex blocks 33 to push the silica gel inner tube 341 and the silica gel outer tube 342 outwards. Subsequently, the power motor 4 can be used to drive the rotating shaft 2 to rotate, thereby causing the winding cylinder 3 to rotate synchronously and winding the paper towel onto the silica gel outer tube 342. After winding is completed, the paper towel is disconnected, and then the gas in the expansion airbag 32 is discharged through the one-way valve tube 35, thereby causing the expansion airbag 32 to contract, and then synchronously causing the silica gel inner tube 341 and the silica gel outer tube 342 to contract through the outer convex blocks 33, so that the outer surface of the silica gel outer tube 342 loses connection with the inner layer of the wound paper towel. At this time, the paper towel can be removed. During the use process, glue and paper tubes are not required, the winding cost is lower, and the contact between the inner layer of the paper towel and the glue is avoided, and less paper towel is wasted;

[0019] A lifting bracket 5 is further provided between the base 1 and the rotating shaft 2, which is beneficial to adjusting the winding height, thereby making the winding device more adaptable;

[0020] The outer convex blocks 33 are of an arc-shaped block structure, and a frosted layer is provided on the outer surface, which is beneficial to having a higher degree of fit with the silica gel tube 34 and maintaining the outward pushing force. At the same time, the probability of slipping is reduced through the frosted layer;

[0021] A number of friction convex blocks 343 are provided on the outer wall of the silica gel outer tube 342. In this embodiment, there are twenty-four, which is beneficial to increasing the friction force between the outer wall of the silica gel outer tube 342 and the paper towel, so that the paper towel can better adhere to the silica gel outer tube 342 without slipping;

[0022] Between the outer wall of the silica gel inner tube 341 and the inner wall of the silica gel outer tube 342, there are also several suction and pressure frames 345. In this embodiment, there are eight of them, which are beneficial to absorbing excessive pressure, reducing the extrusion of the silica gel outer tube 342 on the inner wall of the wound paper towel, and avoiding damage to the paper towel.

[0023] The working principle of the present utility model: When the present utility model is in use, the paper towel is pulled to the surface of the silica gel outer tube 342 and the paper towel is squeezed so that the paper towel adheres to the silica gel outer tube 342. Subsequently, the expansion airbag 32 is inflated through the one-way valve tube 35, so that the expansion airbag 32 expands and pushes the outer convex block 33 outwards, causing the outer convex block 33 to push the silica gel inner tube 341 and the silica gel outer tube 342 outwards. Subsequently, the power motor 4 can be used to drive the rotating shaft 2 to rotate, thereby causing the winding cylinder 3 to rotate synchronously and winding the paper towel onto the silica gel outer tube 342. After the winding is completed, the paper towel is disconnected, and then the gas in the expansion airbag 32 is discharged through the one-way valve tube 35, thereby causing the expansion airbag 32 to contract, and then causing the silica gel inner tube 341 and the silica gel outer tube 342 to contract synchronously through the outer convex block 33, so that the outer surface of the silica gel outer tube 342 loses connection with the inner layer of the wound paper towel. At this time, the paper towel can be taken off. During the use process, glue and paper tubes are not required, the winding cost is lower, and the contact between the inner layer of the paper towel and the glue is avoided, and less paper towel is wasted.
