Description

Technical Field

[0001] This utility model relates to the field of tissue embossing roller technology, and in particular to a replaceable tissue embossing roller structure. Background Technology

[0002] Currently, in the paper towel production process, heated embossing rollers are used to emboss the paper towels. Heating makes the paper fibers more prone to plastic deformation under pressure, forming a stable embossed pattern structure, which facilitates the processing of paper towels.

[0003] Among them, a search revealed Chinese patent CN222844943U, which discloses an embossing roller for paper product production. In the application of the above-mentioned patent's technical solution, since the embossing cylinder on the embossing roller body is an integral structure, the roller body needs to be disassembled in order to slide the embossing cylinder out from one end of the roller body, which is inconvenient for replacing the embossing cylinder. Therefore, in order to better realize the function of replacing the embossing cylinder on the embossing roller, promote the technological progress of the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the embossing cylinder structure of the embossing roller in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the embossing cylinder is not easy to remove and replace in the existing embossing roller structure, and to propose a replaceable tissue embossing roller structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A replaceable tissue embossing roller structure includes a fixed shaft and a resistance heating rod. A rotating cylinder is rotatably mounted on the outer wall of the fixed shaft via an interlocking bearing. An embossing cylinder assembly is provided on the outer wall of the rotating cylinder. The embossing cylinder assembly includes two embossing arc plates, which cover the outer side of the rotating cylinder. Connecting arc plates are fixedly connected to both ends of the inner side of the embossing arc plates. Pressure rings are slidably sleeved at both ends of the rotating cylinder, pressing against the outer side of the connecting arc plates. Two connecting arc grooves are provided on the circumferential outer wall of the rotating cylinder, and the connecting arc plates are engaged with the connecting arc grooves. Multiple first mounting holes are provided on the circumference of the pressure rings, and first screws are inserted into the first mounting holes. One end of the first screw is threadedly connected to the rotating cylinder.

[0006] Furthermore, the inner side of the embossed arc plate is provided with multiple positioning grooves.

[0007] Furthermore, the outer circumferential wall of the rotating cylinder is integrally formed with multiple positioning strips, which are inserted into positioning grooves.

[0008] Furthermore, the pressure ring has multiple second mounting holes around its circumference, and a second screw is inserted into each second mounting hole. One end of the second screw is threadedly connected to the connecting arc plate.

[0009] Furthermore, a movable cylinder is fixedly connected to the outer circumferential wall of the fixed shaft, and the movable cylinder is located inside the rotating cylinder.

[0010] Furthermore, one end of the fixed shaft is provided with a connecting hole, and the resistance heating rod is disposed in the connecting hole.

[0011] Furthermore, one end of the resistance heating rod is electrically connected to a connecting wire.

[0012] The beneficial effects of this utility model are as follows: 1. By wrapping two embossed arc plates around the outer surface of the rotating cylinder, and then pushing the pressure ring to press it against the outside of the connecting arc plates, the embossed arc plates are fixedly installed on the rotating cylinder using the first screw and the second screw, thereby quickly replacing the embossed cylinder with a new pattern and the worn embossed cylinder.

[0013] 2. By using positioning strips and positioning grooves for insertion, the connection between the embossing arc plate and the rotating cylinder is strengthened, thereby improving the stability of the embossing cylinder installation. Attached Figure Description

[0016] 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.

[0017] Reference Figures 1-5 A replaceable tissue embossing roller structure includes a fixed shaft 1 and a resistance heating rod 2. The fixed shaft 1 is used to support the entire device and provide basic support for other components. A rotating cylinder 3 is rotatably mounted on the outer wall of the fixed shaft 1 via an interlocking bearing. An embossing cylinder assembly 4 is provided on the outer wall of the rotating cylinder 3. The embossing cylinder assembly 4 includes two embossing arc plates 401, which cover the outer side of the rotating cylinder 3. Connecting arc plates 402 are welded to both ends of the inner side of the embossing arc plates 401. Pressure rings 5 ​​are slidably sleeved at both ends of the rotating cylinder 3. The pressure rings 5 ​​press against the outer side of the connecting arc plates 402. Two connecting arc grooves 6 are provided on the outer circumference of the rotating cylinder 3. The connecting arc plates 402 are engaged with the connecting arc grooves 6. The pressure ring 5 has multiple first mounting holes 7 around its circumference. A first screw 8 is inserted into the first mounting hole 7 and one end of the first screw 8 is threaded to the rotating cylinder 3. The pressure ring 5 has multiple second mounting holes 9 around its circumference. A second screw 10 is inserted into the second mounting hole 9 and one end of the second screw 10 is threaded to the connecting arc plate 402. The two embossed arc plates 401 with the new pattern are wrapped around the outer surface of the rotating cylinder 3. The pressure ring 5 is then pushed to press it against the outside of the connecting arc plate 402. The pressure ring 5 is then fixed with the first screw 8 and the second screw 10, thereby fixing the embossed arc plate 401 onto the rotating cylinder 3.

[0018] The inner side of the embossed arc plate 401 is provided with multiple positioning grooves 403, and the outer circumference of the rotating cylinder 3 is integrally formed with multiple positioning strips 13. The positioning strips 13 are inserted into the positioning grooves 403 to strengthen the connection between the embossed arc plate 401 and the rotating cylinder 3.

[0019] A movable cylinder 11 is fixed to the outer circumference of the fixed shaft 1 by bolts. The movable cylinder 11 is located inside the rotating cylinder 3, thereby supporting the rotating cylinder 3.

[0020] One end of the fixed shaft 1 is provided with a connecting hole 12, and the resistance heating rod 2 is installed in the connecting hole 12. The resistance heating rod 2 adopts a single-head electric heating tube of model JSKTR, with a working voltage of 12-350V and a heating power of 20W-3000W. The resistance heating rod 2 serves as a heating component to provide heat energy to the material.

[0021] One end of the resistance heating rod 2 is electrically connected to a connecting wire.

[0022] The working principle of this embodiment is as follows: When it is necessary to replace the embossing cylinder assembly 4, unscrew the first screw 8 and the second screw 10, then push the pressure ring 5 to remove the pressure ring 5 from the connecting arc plate 402, and then pry the two embossing arc plates 401 open to both sides to remove the embossing arc plates 401. Then, wrap the two embossed arc plates 401 with the new pattern around the outer surface of the rotating cylinder 3, and push the pressure ring 5 to press it against the outside of the connecting arc plate 402. At the same time, the positioning strip 13 is inserted into the positioning groove 403 to strengthen the connection between the embossed arc plate 401 and the rotating cylinder 3. Then, use the first screw 8 and the second screw 10 to fix the pressure ring 5, thereby fixing the embossed arc plate 401 on the rotating cylinder 3.
