Technical Field

[0001] The utility model relates to the technical field of PVC tablecloth processing, in particular to a PVC tablecloth edge grinding device. Background Art

[0002] PVC tablecloths play an important role in modern life, and their functions and application scenarios are extensive and diverse. It can effectively prevent sharp objects from directly contacting the tabletop, reducing scratches and wear. It can also produce tablecloths in a variety of colors and patterns to meet different decorative needs. It has natural waterproof performance and is easy to wipe clean after being stained with oil or water, with simple maintenance, so it plays an irreplaceable role in modern life.

[0003] When processing PVC tablecloths, the preliminarily extruded and formed PVC tablecloths need to be cut. The cross-section of the cut PVC tablecloth is in a vertical plane shape, and the cross-section is at a right angle to the surface of the PVC tablecloth. It is easy to be cut by the edge of the PVC tablecloth when passing by hand. Therefore, after the PVC tablecloth is cut, it generally needs to be subjected to separate corner grinding treatment. During the grinding process, the PVC tablecloth needs to be positioned again, and the processing steps are relatively cumbersome, and the processing efficiency is low, resulting in a relatively high production cost per piece of PVC tablecloth. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a PVC tablecloth edge grinding device to solve the problem that after the PVC tablecloth is cut, it generally needs to be subjected to separate corner grinding treatment, and the PVC tablecloth needs to be positioned again during the grinding process, resulting in relatively cumbersome processing steps.

[0005] To achieve the above purpose, the basic scheme of the utility model is as follows: A PVC tablecloth edge grinding device, comprising:

[0006] A support roller located between the traction powers of the PVC tablecloth, and the support roller is horizontally arranged;

[0007] Two relatively arranged clamping and grinding units, the clamping and grinding units are detachably installed on the support roller, and the clamping and grinding units can slide or be locked along the axial direction of the support roller.

[0008] The technical principle of the utility model is that the support roller is not between the traction powers of the PVC tablecloth, which is convenient for the clamping and grinding unit on the support roller to grind the PVC tablecloth during the transmission process. The edge of the PVC tablecloth can be ground without setting a separate grinding step, and the grinding efficiency is significantly improved. At the same time, the clamping and grinding unit can be horizontally slid on the support roller to adjust the position and then be locked, which is convenient for adapting to different widths of the PVC tablecloth, can improve the applicable PVC tablecloth specifications of the PVC tablecloth edge grinding device, and reduce the edge grinding cost of the PVC tablecloth.

[0009] Furthermore, the clamping and grinding unit includes:

[0010] A fixed sliding assembly, which is detachably connected to the support roller, and the fixed sliding assembly can slide or lock along the axial direction of the support roller;

[0011] A grinding block, the longitudinal section of which is in a "U" shape, and the grinding block is horizontally arranged, the openings of the grinding blocks face each other, and a first grinding layer is fixedly laid on the inner wall of the grinding block;

[0012] A pressing and adjusting plate, which is horizontally installed in the grinding block, and the lower surface of the pressing and adjusting plate faces the lower surface of the inner wall of the grinding block, and a second grinding layer is fixedly laid on the lower surface of the pressing and adjusting plate;

[0013] A number of telescopic rods located between the upper surface of the pressing and adjusting plate and the grinding block.

[0014] Through the above settings, the grinding block can cooperate with the pressing and adjusting plate and the telescopic rods, so that a grinding space for the PVC tablecloth is formed between the inner wall of the grinding block and the lower surface of the pressing and adjusting plate, and the second grinding layer and the first grinding layer act together to comprehensively grind the edge of the PVC tablecloth.

[0015] Furthermore, the fixed sliding assembly includes:

[0016] A hoop that can be detached or clamped on the support roller;

[0017] A number of support columns, the upper ends of the support columns are fixedly connected to the lower side of the grinding block, and the lower ends of the support columns are fixedly connected to one outer wall of the hoop or are respectively hinged to the two outer walls of the hoop.

[0018] Through the above settings, the setting of the hoop makes it more convenient for the clamping and grinding unit to be disassembled and assembled and horizontally slid on the support roller; at the same time, the setting of the support columns makes the connection between the hoop and the grinding block more stable and convenient.

[0019] Furthermore, the corner between the lower side and the vertical side wall of the inner wall of the grinding block is a first rounded surface.

[0020] Through the above settings, it is convenient for the first grinding layer at the first rounded surface to fully contact the edge of the PVC tablecloth, so that the edge of the PVC tablecloth is rounded and ground.

[0021] Furthermore, one side edge of the pressing and adjusting plate close to the vertical side wall of the grinding block is a second rounded surface that smoothly transitions with the vertical side wall of the grinding block.

[0022] Through the above settings, it is convenient for the second grinding layer at the second rounded surface to fully contact the edge of the PVC tablecloth, so that the edge of the PVC tablecloth is rounded and ground.

[0023] Furthermore, the telescopic rod is a spring rod. The fixed end of the spring rod is fixedly connected to the upper side of the grinding block, and the telescopic end of the spring rod is fixedly connected to the upper side of the pressing adjustment plate.

[0024] With the above arrangement, the spring rod can automatically extend, causing the pressing adjustment plate to automatically press tightly against the PVC tablecloth. As a result, under the action of the traction mechanism, the PVC tablecloth can be stably limited between the pressing adjustment plate and the grinding block.

[0025] Furthermore, several micro rollers that can be tightly pressed against the surface of the PVC tablecloth are rotatably installed on one side of the pressing adjustment plate away from the vertical side wall of the grinding block. The rotation axis of the micro rollers is parallel to the axis of the support roller.

[0026] With the above arrangement, the micro rollers at the edge of the pressing adjustment plate also stably roll on the PVC tablecloth, making the layout and installation of the PVC tablecloth stable. The micro rollers can also ensure that the PVC tablecloth is stably pulled. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0031] This embodiment is basically as Figure 1 and Figure 2 shown. An embodiment of the present invention provides a PVC tablecloth edge grinding device, including a support roller 10 located between the traction powers of the PVC tablecloth and two relatively arranged clamping and grinding units. The support roller 10 is horizontally arranged, and fixed blocks 101 are provided at both ends of the support roller 10.

[0032] As Figure 2As shown in the figure, the clamping and grinding unit includes a fixed sliding component, a grinding block 20, a pressing and adjusting plate 40, and a number of telescopic rods located between the upper surface of the pressing and adjusting plate 40 and the grinding block 20. The fixed sliding component includes a hoop 30 that can be detachably or clamped to the support roller 10 and two support columns 301. The upper ends of the support columns 301 are fixedly connected to the lower side of the grinding block 20, and the lower ends of the two support columns 301 are respectively hinged to the outer walls on both sides of the hoop 30. The corner between the lower side of the inner wall of the grinding block 20 and the vertical side wall is a first rounded surface 202. An anti-slip rubber layer 302 is fixedly bonded to the inner wall of the hoop 30, which can achieve fixed fitting and detachable connection with the outer wall of the support roller 10. At the same time, the longitudinal section of the grinding block 20 is "U"-shaped, and the grinding block 20 is horizontally arranged. The openings 201 of the grinding block 20 are opposite to the openings 201 of another grinding block 20. A first grinding layer 203 is fixedly laid on the inner wall of the grinding block 20. The pressing and adjusting plate 40 is horizontally installed in the grinding block 20, and the lower surface of the pressing and adjusting plate 40 is directly opposite to the lower surface of the inner wall of the grinding block 20. A second grinding layer 401 is fixedly laid on the lower surface of the pressing and adjusting plate 40.

[0033] At the same time, as Figure 2 shown, the telescopic rod is a spring rod 402. The fixed end of the spring rod 402 is fixedly connected to the upper side of the grinding block 20, and the telescopic end of the spring rod 402 is welded to the upper side of the pressing and adjusting plate 40. A number of micro rollers 403 that can be pressed against the surface of the PVC tablecloth are rotatably installed on one side of the pressing and adjusting plate 40 away from the vertical side wall of the grinding block 20. The rotation axis of the micro rollers 403 is parallel to the axis of the support roller 10.

[0034] When the PVC tablecloth edge grinding device in this embodiment is in use, first control the number of clamping and grinding units according to the number of PVC tablecloths conveyed at the support roller 10. The number of clamping and grinding units is twice the number of PVC tablecloths conveyed. When installing the clamping and grinding units, the openings 201 of the grinding blocks 20 in the two clamping and grinding units are arranged opposite to each other, which is convenient for synchronously supporting both sides of the PVC tablecloth and synchronously grinding.

[0035] When installing the clamping and grinding unit, first loosen the hoop 30 so that the hoop 30 is wrapped around the support roller 10. The hoop 30 is clamped and installed on the support roller 10. The anti-slip rubber layer 302 on the inner wall of the hoop 30 can stably fit on the outer wall of the support roller 10 to fix the entire clamping and grinding unit. During this process, the lower end of the support column 301 is hinged and rotated relative to the outer walls on both sides of the hoop 30, so that the installation and relative flipping at both ends of the hoop 30 do not affect the grinding block 20, making the setting of the grinding block 20 stable. When it is necessary to adjust the position of a single clamping and grinding unit according to the width of the PVC tablecloth, slightly loosen the hoop 30 and control the entire clamping and grinding unit to slide or rotate horizontally along the support roller 10, so as to control the circumferential position and horizontal position of the entire clamping and grinding unit relative to the support roller 10. The grinding position of the grinding block 20 is also adjusted synchronously. The entire clamping and grinding unit has good adjustability and good stability during grinding support.

[0036] When grinding the PVC tablecloth, the free end of the PVC tablecloth sequentially passes through between the opening 201 of the grinding block 20 and the lower side of the pressing and adjusting plate 40, so that the first rounded surface 202 and the second rounded surface at the edge of the PVC tablecloth are in contact, and are in contact with the first grinding layer 203 and the second grinding layer 401. At this time, the spring rod 402 on the pressing and adjusting plate 40 automatically extends, so that the pressing and adjusting plate 40 is pressed tightly on the upper surface of the PVC tablecloth, making the PVC tablecloth, the grinding block 20 and the pressing and adjusting plate 40 stably fit. At the same time, the micro rollers 403 at the edge of the pressing and adjusting plate 40 also stably roll on the PVC tablecloth, making the arrangement and installation of the PVC tablecloth stable.

[0037] When the traction power drives the PVC tablecloth to move horizontally, under the action of the traction force, the edge of the PVC tablecloth is fully ground by the first grinding layer 203 and the second grinding layer 401, realizing linear grinding treatment of the edge of the PVC tablecloth, achieving synchronous grinding during the conveying process, with high grinding efficiency and high grinding accuracy.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
