Description

Technical Field

[0001] This utility model relates to an embossing device, specifically a PVC tablecloth embossing device, belonging to the field of PVC tablecloth production technology. Background Technology

[0002] PVC tablecloths are a common type of tablecloth. They are primarily made of soft polyvinyl chloride plastic, with plasticizers, lubricants, stabilizers, and fillers added during processing. PVC tablecloths are waterproof, oil-proof, heat-resistant, and require no washing. They effectively protect tabletops from wear, scratches, stains, and spills, and also block UV rays, maintaining the original appearance of the tabletop. PVC tablecloths come in transparent, semi-transparent, and opaque types. Transparent PVC tablecloths clearly showcase the texture of the tabletop and items, suitable for users who prefer a simple and aesthetically pleasing look. PVC tablecloths have high wear resistance and tear resistance, are not easily cut, and have a long service life. They are easy to clean, with a smooth surface; stains are easily wiped away with a damp cloth, eliminating the need for frequent washing. PVC tablecloths are relatively inexpensive and functional, making them an economical and affordable tabletop protection product.

[0003] The texture on PVC tablecloths is created by applying pressure to the rollers. When different textures are needed, the rollers are replaced. However, replacing existing rollers requires disassembling many fixed parts, which takes a lot of time and is inefficient, thus reducing production efficiency. To address these issues, we provide a PVC tablecloth embossing device. Utility Model Content

[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figures 1-7 A PVC tablecloth embossing device includes a frame 1 and a pressure roller 2. Two support seats 3 are installed on the top of the frame 1 and are symmetrical to each other. The frame 1 provides support and load for the required components, and the support seats 3 maintain the stability of the pressure roller 2 and the rotating roller 4.

[0025] A rotating roller 4 is rotatably connected to the inner wall of the support base 3. A slide rail 5 is provided on the inner side of the support base 3. A slide block 6 is slidably connected to the inner wall of the slide rail 5. A first lead screw 7 is rotatably connected to the upper surface of the slide block 6. The slide rail 5 provides space for the slide block 6 to move. When the slide block 6 moves, it drives the pressure roller 2 to move at the same time. By moving the position of the pressure roller 2, the distance between it and the rotating roller 4 is changed, so that the distance between the rotating roller 4 and the pressure roller 2 can be used to process PVC tablecloths of different thicknesses. The first lead screw 7 is used as a power source to provide power for the slide block 6 to move.

[0026] The inner wall of the slide 6 is rotatably connected to a rotating seat 8. A groove 9 is provided on the inner side of the rotating seat 8. The end of the pressure roller 2 is located inside the groove 9 and above the rotating roller 4. The groove 9 accommodates the end of the pressure roller 2, partially enclosing the end of the pressure roller 2 inside. The end of the pressure roller 2 is square, and the inner cavity of the groove 9 is also square.

[0027] A sleeve 10 is slidably connected to the outer surface of the rotating seat 8, and the sleeve 10 is located outside the slot 9. A pull plate 11 is connected to one side of the sleeve 10. A moving groove 13 is opened on the inner side of the rotating seat 8, which provides space for the pull plate 11 to move. The outer surface of the pull plate 11 is slidably connected to the inner wall of the moving groove 13. A second lead screw 12 is rotatably connected to the inner wall of the rotating seat 8. The outer surface of the second lead screw 12 is threadedly connected to the inner wall of the pull plate 11. A four-corner head 14 is connected to one end of the second lead screw 12 located outside the rotating seat 8. The rotation of the second lead screw 12 provides power for the movement of the sleeve 10. After the second lead screw 12 rotates, it drives the pull plate 11 to move. The pull plate 11 drives the sleeve 10 to move. After the sleeve 10 moves, it wraps the end of the pressure roller 2 inside, so that the pressure roller 2 cannot detach from the rotating seat 8 and maintains the stability of the pressure roller 2. The four-corner head 14 is connected to a wrench, which makes it easy for the wrench to rotate the second lead screw 12.

[0028] The second lead screw 12 is externally equipped with a positioning mechanism 15. When the pressure roller 2 rotates, it may wobble. To prevent the second lead screw 12 from rotating due to this wobble and losing support for the sleeve 10, the positioning mechanism 15 maintains the stability of the second lead screw 12. The positioning mechanism 15 includes a sliding sleeve 1501, one side of which is connected to one end of the rotating seat 8. A sleeve 1502 is slidably connected to the inner wall of the sliding sleeve 1501. The sliding sleeve 1501 supports the sleeve 1502. 502 provides support and maintains the stability of sleeve 1502. One end of sleeve 1502 located outside sleeve 1502 is connected to a first retainer 1503, and one side of the four corner head 14 is connected to a second retainer 1504. The second retainer 1504 is in contact with the first retainer 1503. The first retainer 1503 provides resistance to the second retainer 1504, limiting the rotation of the second retainer 1504. The second retainer 1504 transmits the resistance to the second lead screw 12, maintaining the stability of the second lead screw 12.

[0029] A spring 1505 is sleeved on the outside of the second lead screw 12. One end of the spring 1505 is connected to the inner top wall of the sleeve 1502, and the other end of the spring 1505 is connected to the inner bottom wall of the sliding sleeve 1501. The spring 1505 provides an elastic pushing force to the first baffle 1503. While pushing the sleeve 1502 to move, the spring 1505 also drives the first baffle 1503 to move at the same time. The first baffle 1503 is in tight contact with the second baffle 1504 by the pushing of the spring 1505.

[0030] The inner side of the sliding sleeve 1501 is provided with a sliding groove 1506 and a retaining groove 1507, and the sliding groove 1506 and the retaining groove 1507 are connected. A pull rod 1508 is connected to the outer surface of the sleeve 1502. The outer surface of the pull rod 1508 is in contact with the inner wall of the sliding groove 1506. The retaining groove 1507 is adapted to the pull rod 1508. The sliding groove 1506 provides space for the pull rod 1508 to move, and the retaining groove 1507 restricts the movement of the pull rod 1508. By pulling the pull rod 1502... 08 drives the sleeve 1502 to move to a different position. At the same time, the sleeve 1502 moves to a different position, and the first baffle 1503 moves to a different position. After the first baffle 1503 moves to a different position, it disengages from the second baffle 1504, releasing the positioning restriction on the second baffle 1504. When the first baffle 1503 does not need to provide resistance to the second baffle 1504, the pull rod 1508 is pulled into the retaining groove 1507. The retaining groove 1507 restricts the first baffle 1503 from resetting and restricts the first baffle 1503 from contacting the second baffle 1504.

[0031] A motor 16 is installed on one side of the support base 3. The output shaft of the motor 16 is connected to one end of the rotating roller 4. The motor 16 serves as the power source to provide power for the rotation of the rotating roller 4. Both the rotating roller 4 and the pressure roller 2 are connected to pulleys 17 at the ends away from the motor 16. A transmission belt 18 is sleeved on the outside of the pulley 17, and the pulleys 17 are connected to each other through the transmission belt 18. A tension roller 19 is installed on one side of the support base 3. The outer surface of the tension roller 19 is in contact with the outer surface of the transmission belt 18. The power of the rotating roller 4 is transmitted to the pressure roller 2 through the transmission belt 18, thereby driving the pressure roller 2 to rotate together with the rotating roller 4. After the pressure roller 2 is adjusted to the correct position, the transmission belt 18 may become loose or over-tensioned. The tension roller 19 adjusts the tension of the transmission belt 18 accordingly.

[0032] The upper surface of the support base 3 is connected to the support plate 20. The outer surface of the first lead screw 7 is threadedly connected to the inner wall of the support plate 20. The top of the first lead screw 7 is connected to the handwheel 21. The support plate 20 provides support force to the first lead screw 7 and maintains the stability of the first lead screw 7. The handwheel 21 increases the contact area between the first lead screw 7 and the hand, making it easier for the hand to rotate the first lead screw 7.

[0033] In use, this invention works as follows: First, the pull rod 1508 moves the sleeve 1502 to a new position. Simultaneously, the sleeve 1502 disengages the first baffle 1503 from contact with the second baffle 1504. This disengagement releases the positioning restriction on the second lead screw 12. Next, the pull rod 1508 is rotated into the retaining groove 1507, which then blocks the pull rod 1508, restricting the movement of the first baffle 1503. Finally, the wrench is engaged with the four-corner head 14 to rotate the second lead screw 12. After rotation, the second lead screw 12, via the pull plate 11, moves the retaining sleeve 10 to a new position, disengaging it from contact with the pressure roller 2. After the sleeve 10 releases the restriction on the pressure roller 2, the pressure roller 2 can be removed from the slot 9. Then, the pressure roller 2 to be replaced is placed into the slot 9. Then, the second lead screw 12 is rotated in the reverse direction by the wrench. The second lead screw 12 pushes the pull plate 11 to move its position. The pull plate 11 pushes the sleeve 10 to wrap around the pressure roller 2, restricting the pressure roller 2 inside the slot 9 and maintaining the stability of the pressure roller 2. Then, the pull rod 1508 is moved out from the retaining groove 1507. Then, the spring 1505 pushes the sleeve 1502 to move its position. The sleeve 1502 pushes the first retaining plate 1503 to contact the second retaining plate 1504, restricting the rotation of the second lead screw 12 and maintaining the stability of the second lead screw 12.
