[0002] Embossing equipment is one of the important pieces of equipment in the production process of PVC tablecloths. It is mainly used for embossing the surface of PVC tablecloths to improve the diversity of patterns on the surface of PVC tablecloths and meet people's production and life needs.

[0003] According to Chinese Patent Publication No. CN221793797U, a three-layer PVC tablecloth embossing device is disclosed. It uses a motor to drive the transmission roller to rotate, which drives the PVC tablecloth to be conveyed. During the conveying process, the tablecloth is squeezed by the driven embossing roller, which can achieve a high-efficiency and stable embossing effect. This ensures that each tablecloth has a consistent pattern. Since the driven embossing roller adopts a detachable installation design, the embossing cylinder can be easily replaced, thereby achieving different embossing effects. This makes the device suitable for producing a variety of PVC tablecloth products, and adjusting the pattern is very simple.

[0004] In the above-mentioned technical solution, when the PVC tablecloth is transferred and embossed between the driven embossing roller and the transmission roller, the transmission path is prone to deviation, which makes the embossing of the driven embossing roller on the PVC tablecloth prone to deviation, thus greatly affecting the embossing quality of the PVC tablecloth and affecting the normal use of the PVC tablecloth in the future. To this end, we propose a PVC tablecloth embossing device. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1:

[0027] A preferred embodiment of the PVC tablecloth embossing device provided by this utility model is, for example... Figures 1 to 6 As shown: A PVC tablecloth embossing device includes a frame 1, a driven embossing roller 7 and a transmission roller 4. A rotating shaft 3 is rotatably connected to the inner side of the frame 1 via a bearing seat. The transmission roller 4 is fixedly sleeved on the outer wall of the rotating shaft 3. A support frame 28 is fixedly installed at the top of the frame 1. A cylinder 5 is fixedly installed at the top of the support frame 28. An installation plate 20 is fixedly installed at the output end of the cylinder 5. A fixing frame 6 is provided at the bottom of the installation plate 20. A connecting component is provided between the fixing frame 6 and the installation plate 20. A rotating shaft 8 is rotatably connected to the inner wall of the fixing frame 6 via a bearing seat. The driven embossing roller 7 is fixedly sleeved on the outer wall of the rotating shaft 8. Stabilizing components are provided in front of and behind the transmission roller 4.

[0028] The stabilizing assembly includes a bidirectional screw 9, a first limiting frame 13, and a second limiting frame 14. The bidirectional screw 9 movably passes through one side of the frame 1 and is rotatably connected to the frame 1 via bearings. Connecting blocks 10 are fixedly installed at the bottom of both the first limiting frame 13 and the second limiting frame 14. Both connecting blocks 10 are threaded onto the outer wall of the bidirectional screw 9. Fixing frames 15 are fixedly installed at the bottom of the inner walls of both the first limiting frame 13 and the second limiting frame 14. A support roller 16 is rotatably connected to the inner wall of the fixing frame 15 via a bearing seat. A cylinder 17 is fixedly installed at the top of both the first limiting frame 13 and the second limiting frame 14. A fixing frame 18 is fixedly installed at the output end of the cylinder 17. A clamping roller 19 is rotatably connected to the inner wall of the fixing frame 18 via a bearing seat.

[0029] Specifically, in the above technical solution, when using the PVC tablecloth embossing device, the PVC tablecloth passes between the driven embossing roller 7 and the transmission roller 4. Then, cylinder 5 is activated, causing the fixed frame 6 to move downwards. The fixed frame 6, through the rotating shaft 8, drives the driven embossing roller 7 downwards, causing the driven embossing roller 7 to squeeze the PVC tablecloth. Then, according to the specifications of the PVC tablecloth, the rotating plate 30 is rotated, causing the rotating plate 30 to drive the bidirectional screw 9 to rotate. The bidirectional screw 9 drives the two connecting blocks 10 on it to move closer together. The two connecting blocks 10 respectively drive the limiting frame 13 and the limiting frame 2 14 to move closer together, allowing the PVC tablecloth to pass between the clamping roller 19 and the support roller 16 on the limiting frame 13 and the limiting frame 2 14. Then, cylinder 17 is activated, causing... Cylinder 2 17 drives the fixed frame 2 18 to move downwards, causing the fixed frame to drive the clamping roller 19 to move downwards. Ultimately, the clamping roller 19 and the support roller 16 press the PVC tablecloth together. Then, the PVC tablecloth is conveyed through the conveying equipment. Through the above structure, the PVC tablecloth can be limited and stabilized during the conveying and embossing process, thereby improving the stability of the PVC tablecloth during the conveying process and ensuring the embossing accuracy of the PVC tablecloth. This solves the problem in the existing technology where the PVC tablecloth is easily deviated from its conveying path when it is conveyed and embossed between the driven embossing roller 7 and the transmission roller 4, which leads to deviations in the embossing of the driven embossing roller 7 on the PVC tablecloth, thus greatly affecting the embossing quality of the PVC tablecloth and its subsequent normal use.

[0030] Furthermore, a limiting rod 11 is fixedly installed on the inner wall of the frame 1, and rod holes 12 are opened on both connecting blocks 10, with the limiting rod 11 moving through the rod holes 12.

[0031] The limiting rod 11 can limit the movement of the connecting block 10, ensuring its stability during movement.

[0032] Furthermore, a rotating plate 2 is fixedly installed at one end of the bidirectional screw 9;

[0033] The rotating plate 2 allows personnel to easily rotate the bidirectional screw 9, thus facilitating operation.

[0034] Example 2:

[0035] Based on Embodiment 1, a preferred embodiment of the PVC tablecloth embossing device provided by this utility model is, for example... Figures 1 to 6 As shown: The stabilizing component includes a positioning post 21 and a retaining frame 23. The positioning post 21 is fixedly installed on the top of the fixing frame 6. The mounting plate 20 has a post hole 22. The positioning post 21 moves through the post hole 22. The retaining frame 23 is slidably connected to the top of the fixing frame 6. The outer wall of the positioning post 21 has a retaining groove 29. The retaining frame 23 is engaged in the retaining groove 29.

[0036] Specifically, in the above technical solution, when different patterns need to be embossed, the frame 23 can be pulled outward, causing the frame 23 to drive the slider 24 to compress the spring 26, thus disengaging the frame 23 from the slot 29. At this time, the fixing bracket 6 can be detached from the mounting plate 20, allowing the driven embossing roller 7 to be disassembled and replaced. The driven embossing roller 7 with the desired pattern is then installed, with the positioning post 21 passing through the post hole 22. Then, the frame 23 is released, and the slider 24, under the restoring force of the spring 26, drives the frame 23 to engage in the slot 29, thereby completing the installation. Through the above structure, it is convenient for personnel to disassemble and replace the driven embossing roller 7, improving the work efficiency of personnel. It also facilitates the device to emboss different patterns on PVC tablecloths, reducing the limitations of the device's use. The structure is simple and highly practical.

[0037] Furthermore, a slider 24 is fixedly installed at the bottom of the card frame 23, and a groove 27 is opened at the top of the fixing frame 6. The slider 24 is slidably connected to the groove 27. A slide rod 25 is fixedly installed on the inner wall of the groove 27. The slide rod 25 moves through the slider 24. A spring 26 surrounds the outer wall of the slide rod 25. The spring 26 is fixedly installed between one side of the slider 24 and the inner wall of the groove 27.

[0038] By setting the slider 25, the slider 24 and the spring 26 can be limited to ensure the stability of the slider 24 when moving and the spring 26 when compressed.

[0039] Furthermore, there are two positioning posts 21 and two post holes 22, and the positioning posts 21 and post holes 22 are adapted to each other, and the card frame 23 is adapted to the card slot 29.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
