Description

Technical Field

[0001] The utility model belongs to the technical field of tissue production, and particularly relates to an embossing device for tissue production. Background Technique

[0002] Tissue is a common personal hygiene product in daily life, mainly used for wiping, cleaning and other purposes. Common ones include facial tissue, napkin, handkerchief paper, toilet paper, etc. They are usually made of virgin wood pulp, bamboo pulp or other plant fibers and are produced through a series of processes such as pulping, papermaking, cutting, and packaging. The embossing device for tissue production is a mechanical device used to add patterns or textures to the surface of tissue during the tissue manufacturing process. This process not only increases the aesthetics of the tissue but may also improve its water absorption or touch. The embossing device usually includes a pair or more embossing rollers. When the paper passes between this pair of embossing rollers, the raised patterns on the embossing rollers will imprint corresponding patterns on the paper. The existing embossing device for tissue production realizes embossing through two embossing rollers, and the embossing rollers are fixed by bolts. The process of manually disassembling and reinstalling the bolts takes a long time, affecting production efficiency, and frequent disassembly may cause the bolts to loosen or be damaged, increasing maintenance costs and potential safety hazards.

[0003] For example, the utility model with the publication number CN216032861U discloses an embossing device for tissue production. In the patent solution, the embossing die for tissue is fixed by bolts. Every time different patterned embossing rollers need to be replaced, the operator needs to disassemble the bolts. This process is both time-consuming and laborious, and the thread will be worn due to frequent disassembly and assembly. In the long run, the fixing stability will be affected, increasing maintenance costs and safety risks. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides an embossing device for tissue production, which can quickly disassemble and assemble the embossing rollers without disassembling the bolts, significantly shortening the time for replacing the embossing rollers, reducing production interruptions, improving the overall efficiency of the production line, and also being helpful for daily maintenance, while reducing safety hazards.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A tissue production embossing device, including a frame plate, a connecting plate is arranged at the upper end of the frame plate, two sliding columns are slidably arranged inside the connecting plate, cavity blocks are arranged at the relative inner ends of the two sliding columns, docking blocks are slidably connected inside the two cavity blocks, a rectangular frame is arranged between the two docking blocks, two embossing rollers are rotatably arranged inside the rectangular frame, a handle is arranged at the upper end of the rectangular block, an elastic driving unit is arranged between the cavity block and the connecting plate, a linkage mechanism is arranged at the outer ends of the sliding columns, a limiting mechanism is arranged at the upper end of the frame plate, the elastic driving unit includes springs arranged between the cavity block and the connecting plate, and the two springs are respectively sleeved on the outer arc surfaces of the corresponding sliding columns. The elastic driving unit includes springs arranged between the cavity block and the connecting plate, and the two springs are respectively sleeved on the outer arc surfaces of the corresponding sliding columns.

[0006] As a further improvement of the present utility model, a support frame is arranged at the lower end of the frame plate.

[0007] As a further improvement of the present utility model, the limiting mechanism includes a connecting frame arranged at the upper end of the frame plate, two electric push rods are arranged inside the connecting frame, and limiting plates are arranged at the telescopic ends of the two electric push rods.

[0008] As a further improvement of the present utility model, guide rollers are respectively rotatably arranged on the left and right sides inside the frame plate.

[0009] As a further improvement of the present utility model, a control panel is arranged on the front side of the frame plate, and the electric push rod is electrically connected to the control panel.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] First, pass the tissue to be printed through the upper end of the left guide roller, then through between the two printing rollers, and then pass the tissue through the lower end of the right guide roller and fix it on an external winding mechanism. Subsequently, the tissue is wound by the winding mechanism, so that the tissue moves through the embossing roller to quickly emboss it.

[0012] Second, by holding the handle and then pressing the rotating frame, the connecting rods on both sides rotate and expand towards each other, driving the sliding columns on the rotating seats on both sides to move away from each other, thereby driving the cavity blocks on both sides to move away from the docking blocks. Subsequently, the operator can take out the printing roller. At this time, the spring is in a compressed state. Then, align the docking blocks on the replaced printing roller with the cavity blocks on both sides, and then release the rotating frame. At this time, the spring quickly rebounds, driving the cavity blocks on both sides to move closer to each other and fit into the inside of the docking blocks, realizing the replacement of the printing roller. It is possible to quickly disassemble and assemble the embossing roller without removing bolts, significantly shortening the time for replacing the embossing roller, reducing production interruptions, improving the overall efficiency of the production line, and also facilitating daily maintenance, while reducing safety hazards.

[0013] Third, by controlling the electric push rod to operate through the control panel, the telescopic end drives the limiting plates on both sides to move closer to each other, thereby realizing the limitation of the moving paper towel and avoiding the situation of the paper towel running out of position, ensuring the printing quality.

[0014] Fourth, the support frame at the lower end of the frame plate can stably support the embossing device, ensuring that the embossing device does not run out of position during operation and making the operation of the embossing device more stable. BRIEF DESCRIPTION OF THE DRAWINGS
