Description

Technical Field

[0001] This utility model relates to the field of tissue paper embossing machine technology, and in particular to a high-efficiency tissue paper embossing machine. Background Technology

[0002] A tissue embossing machine is a mechanical device specifically designed to emboss patterns, textures, or logos onto the surface of tissues. Through physical pressure and process design, it endows tissues with decorative and functional properties, embossing flowers, geometric patterns, cartoon characters, and more on the surface of tissues to enhance the product's visual appeal and meet consumers' pursuit of quality of life. During operation, the tissue embossing machine usually needs to heat the embossing roller to improve the embossing effect and product quality. In most cases, heat is transferred to the surface of the embossing roller through the circulation of heat-conducting oil inside the heating roller.

[0003] Most conventional tissue embossing machines require replacing the embossing rollers with the corresponding pattern if the embossing style needs to be changed. This replacement not only takes time, causing downtime and reduced production, but also requires readjusting the fit between the new embossing roller and external equipment to ensure the heat transfer oil can circulate within the new roller. The entire process is cumbersome, increasing downtime and impacting production efficiency.

[0004] Therefore, a high-efficiency paper towel embossing machine is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency tissue embossing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency tissue paper embossing machine, comprising an embossing machine body, with a first conduit and a second conduit on both sides of the embossing machine body for circulating heat transfer oil, a rubber roller and several embossing rollers in the embossing machine body, and a support frame rotatably connected to the rubber roller; the embossing machine body is provided with a roller changing assembly for changing different embossing rollers, the roller changing assembly including a cam divider fixedly installed on the embossing machine body, a rotating frame fixedly connected to the cam divider, and the rotating frame rotatably connected to several embossing rollers, with a sealing plate in each embossing roller.

[0007] Preferably, a cylinder is fixedly installed in the body of the embossing machine and the cylinder is fixedly connected to the support frame. A sliding groove is opened in the body of the embossing machine and a rubber roller is slidably connected in the sliding groove. A first motor is fixedly installed on the outer plate of the support frame and the output shaft of the first motor is fixedly connected to the rubber roller.

[0008] Preferably, hydraulic cylinders are fixedly installed at both ends of the embossing machine body, the hydraulic cylinders are fixedly connected to the short plate on the first guide tube, and the other hydraulic cylinder is fixedly connected to the long plate on the second guide tube.

[0009] Preferably, both the first and second conduits are provided with oil drain ports, and a rotating plate is rotatably connected to the first conduit.

[0010] Preferably, the inner cavity of the embossing roller has limit grooves at both ends, and the sealing plate is slidably connected in the limit grooves. A tension spring is fixedly connected between the sealing plate and the embossing roller.

[0011] Preferably, a one-way bearing is fixedly connected to the second guide tube, a transmission plate is fixedly connected to the one-way bearing, and a rotating groove adapted to the transmission plate is opened on the embossing roller.

[0012] Preferably, a second motor is fixedly mounted on the long plate of the second conduit, and a main gear is fixedly mounted on the output shaft of the second motor. A driven wheel is fixedly mounted on the second conduit, and the driven wheel meshes with the main gear.

[0013] The beneficial effects of this utility model are:

[0014] This invention enables the replacement of embossing rollers with different patterns by setting up a roller changing assembly to activate the cam divider, which in turn drives several embossing rollers on the rotating frame to rotate. Furthermore, a hydraulic cylinder drives the first and second guide tubes to move, allowing both to enter the embossing rollers and form channels with the inner cavity of the rollers. This facilitates the entry and exit of heat transfer oil into the embossing rollers, achieving heat transfer oil circulation. The rotation of the second guide tube drives the embossing rollers to rotate via a transmission plate, achieving normal operation. The entire process is convenient and fast, reducing downtime caused by changing embossing rollers. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0025] like Figures 1 to 6As shown in the figure, a specific embodiment of this utility model provides a high-efficiency tissue paper embossing machine, including an embossing machine body. The embossing machine body 1 has a first conduit 2 and a second conduit 3 on both sides for circulating heat transfer oil. The embossing machine body 1 contains a rubber roller 4 and several embossing rollers 5. The first conduit 2 and the second conduit 3 are rotatably connected to a high-temperature oil temperature controller via external pipes, allowing the first conduit 2 and the second conduit 3 to freely extend and retract a certain distance. This allows the high-temperature oil temperature controller to heat the heat transfer oil, which is then transported to the embossing rollers 5. The heat transfer oil heats the embossing rollers 5, maintaining a constant temperature. The oil is then transported to the embossing rollers 5 through the first conduit 2 and discharged out through the second conduit 3 before re-entering the machine. The oil flows into a high-temperature oil temperature controller, thus forming a circulation. The high-temperature oil temperature controller is an external device and is existing technology. A support frame 6 is rotatably connected to the rubber roller 4. The embossing machine body 1 is equipped with a roller changing assembly for changing different embossing rollers 5. By setting the roller changing assembly, the embossing rollers 5 can be quickly replaced when it is necessary to change the paper towel embossing pattern, reducing the impact of downtime on production efficiency. At the same time, the first guide tube 2 and the second guide tube 3 can quickly cooperate with the replaced embossing rollers 5 to re-form the heat transfer oil circulation. The roller changing assembly includes a cam divider 7 fixedly installed on the embossing machine body 1. A rotating frame 8 is fixedly connected to the cam divider 7, and the rotating frame 8 is rotatably connected to several embossing rollers 5. A sealing plate 801 is provided in the embossing roller 5.

[0026] like Figures 1 to 6 As shown, specifically, a cylinder 9 is fixedly installed in the body 1 of the embossing machine, and the cylinder 9 is fixedly connected to the support frame 6. A slide groove 10 is opened in the body 1 of the embossing machine, and the rubber roller 4 is slidably connected in the slide groove 10. A first motor 11 is fixedly installed on the outer plate of the support frame 6, and the output shaft of the first motor 11 is fixedly connected to the rubber roller 4. The embossing roller 5 is rotatably mounted on the rotating frame 8. When different embossing rollers 5 are replaced, the cam divider 7 is started to rotate at a certain angle, thereby driving the rotating frame 8 to rotate, and then driving the embossing roller 5 to rotate. The embossing roller 5 with the required pattern is selected by rotating the embossing roller 5 and placed on top of the rubber roller 4. When the tissue paper passes between the embossing roller 5 and the rubber roller 4, the cylinder 9 is started to drive the support frame 6 to move up and down, thereby adjusting the distance between the rubber roller 4 and the embossing roller 5 on the support frame 6. The rubber roller 4 slides in the slide groove 10, thereby adjusting the distance between the two to adapt to tissue paper of different thicknesses. The first motor 11 can drive the rubber roller 4 to rotate, thereby ensuring that the rubber roller 4 operates normally.

[0027] like Figures 1 to 6As shown, specifically, hydraulic cylinders 12 are fixedly installed at both ends of the embossing machine body 1. The hydraulic cylinders 12 are fixedly connected to the short plate on the first guide tube 2. The short plate is located on the first guide tube 2 and is rotatably connected to the first guide tube 2. The other hydraulic cylinder 12 is fixedly connected to the long plate on the second guide tube 3. The long plate is located on the second guide tube 3 and is rotatably connected to the second guide tube 3. In the above process, after the cam divider 7 selects the corresponding embossing roller 5 by rotation, the two hydraulic cylinders 12 are activated, so that the first guide tube 2 and the second guide tube 3 gradually move and insert into the embossing roller 5. Both the first guide tube 2 and the second guide tube 3 are provided with oil drain ports 13, and a rotating plate 14 is rotatably connected to the first guide tube 2. Limit grooves 15 are provided at both ends of the inner cavity of the embossing roller 5, and the sealing plate 801 is slidably connected in the limit groove 15. The sealing plate 801 and the embossing roller are connected to each other. A tension spring 16 is fixedly connected between the 5. When the first conduit 2 and the second conduit 3 are inserted into the embossing roller 5, the rotating plate 14 on the first conduit 2 and the second conduit 3 both apply pressure to the sealing plate 801 in the embossing roller 5 and push the sealing plate 801 to move in the limiting groove 15. The tension spring 16 is stretched under the force and generates a reaction force. After the first conduit 2 and the second conduit 3 enter the inner cavity of the embossing roller 5, the inner cavities of the first conduit 2 and the second conduit 3 can form a communication state with the inner cavity of the embossing roller 5 through the oil outlet 13. Therefore, the heat transfer oil heated by the high temperature oil temperature machine can enter the embossing roller 5 through the first conduit 2 and the oil outlet 13, and enter the second conduit 3 through the oil outlet 13 on the second conduit 3. Then the heat transfer oil in the second conduit 3 re-enters the high temperature oil temperature machine, thereby achieving the circulation of heat transfer oil according to this process.

[0028] like Figures 1 to 6As shown, specifically, a one-way bearing 17 is fixedly connected to the second guide tube 3, and a transmission plate 18 is fixedly connected to the one-way bearing 17. The embossing roller 5 has a rotating groove 19 adapted to the transmission plate 18. During the insertion of the second guide tube 3 into the embossing roller 5, the transmission plate 18 is rotated counterclockwise, thereby adjusting its position on the second guide tube 3 via the one-way bearing 17. This gradually adjusts the position so that the transmission plate 18 is inserted into the rotating groove 19 during the insertion of the second guide tube 3 into the embossing roller 5. The long plate on the second guide tube 3... A second motor 20 is fixedly installed, and a main gear 21 is fixedly installed on the output shaft of the second motor 20. A driven wheel 22 is fixedly installed on the second guide tube 3, and the driven wheel 22 meshes with the main gear 21. Subsequently, the second motor 20 is started, and the second guide tube 3 is driven to rotate through the cooperation between the driven wheel 22 and the main gear 21. Due to the action of the one-way bearing 17, the transmission plate 18 cannot rotate clockwise on the second guide tube 3, thereby driving the second motor 20 so that the rotation of the second guide tube 3 can drive the transmission plate 18 to rotate synchronously through the one-way bearing 17. When the transmission plate 18 is inserted into the rotating groove 19, it drives the embossing roller 5 to rotate. The rotation of the embossing roller 5 causes the sealing plate 801 to rotate, and the sealing plate 801 comes into contact with the rotating plate 14. The rotating plate 14 is rotatably connected to the first guide tube 2. Therefore, the rotation of the sealing plate 801 and the rotation of the embossing roller 5 will not affect the first guide tube 2 inserted in the embossing roller 5. At this time, while the embossing roller 5 is rotating and working normally, the heat transfer oil inside it is circulating normally. When the embossing roller 5 is replaced again, it is stopped by a high-temperature oil temperature controller. The heat transfer oil circulates, the second motor 20 stops driving, the embossing roller 5 stops rotating, the hydraulic cylinder 12 is activated so that the first guide tube 2 and the second guide tube 3 are both disengaged from the embossing roller 5, so that the sealing plate 801 is reset under the reaction force of the tension spring 16, thereby sealing the outlets at both ends of the embossing roller 5, thus preventing a small amount of heat transfer oil in the embossing roller 5 from flowing out. Then the cam divider 7 is activated again so that the embossing roller 5 rotates alternately, thereby replacing the next embossing roller 5, and the subsequent operation of replacing the embossing roller 5 is completed again according to the above process.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
