[0002] Polyvinyl chloride, abbreviated as PVC in English, is a polymer polymerized by a free radical polymerization reaction mechanism under the action of initiators such as peroxides and azo compounds or under the action of light and heat. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively called vinyl chloride resins. PVC was once the most produced general-purpose plastic in the world and has very wide applications. It has extensive applications in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wire and cable, packaging film, bottles, foaming materials, sealing materials, fibers, etc.

[0003] According to a disclosed surface coating device for PVC sheets (publication number: CN211587210U), in the above application, by starting the second cylinder, the PVC sheet to be coated can be suspended and clamped between two fixed plates, and it is not easy to shake, so that the coating effect is good; by starting the second driving motor, the output end of the second driving motor drives the fixed plate to rotate, and the fixed plate drives the clamped PVC sheet to flip, so as to facilitate the coating of both sides of the PVC sheet, which is convenient to use and improves work efficiency. However, during the clamping process of the PVC sheet by this device, the clamping force cannot be controlled, which may cause damage to the outer surface of the PVC sheet due to excessive clamping force, and at the same time, the situation of slipping may occur due to insufficient clamping force.

Detailed implementation mode

[0022] As Figures 1-4 shown, the present utility model provides a technical solution: a PVC sheet surface coating device, including a workbench 1, a support frame 2 is fixedly installed on the workbench 1, a spraying mechanism 3 is fixedly installed on the support frame 2, a mounting plate 4 is fixedly installed on the workbench 1, a motor 5 is fixedly installed on the side wall of the mounting plate 4, a rotating rod 6 is fixedly connected to the output end of the motor 5, and the first clamping plate 7 at the end of the rotating rod 6 driven by the motor 5 can flip the middle PVC sheet, facilitating the coating of the PVC sheet by the spraying mechanism 3. The end of the rotating rod 6 is fixedly connected to the first clamping plate 7. A chute 8 is opened on the workbench 1. The inner wall of the chute 8 is rotatably connected to the end of the first threaded rod 9. The end of the first threaded rod 9 is fixedly installed with a turntable 10. A slider 11 is slidably connected to the inner wall of the chute 8, and a clamping mechanism 12 is arranged on the slider 11.

[0023] In this embodiment, a clamping mechanism 12 is arranged on the slider 11. By squeezing the end of the support rod 128 by the extrusion rod 123 in the clamping mechanism 12, the rubber clamping block 1211 can squeeze the outer wall of the first threaded rod 9, so that the first threaded rod 9 can no longer rotate, preventing the second clamping plate 125 from continuing to move leftward to clamp the PVC sheet, resulting in excessive clamping force. At the same time, by turning the second threaded rod 1210, the rubber clamping block 1211 at the bottom can be driven to adjust the height. By adjusting the distance between the rubber clamping block 1211 and the first threaded rod 9, the clamping force of the first clamping plate 7 and the second clamping plate 125 on the PVC sheet can be adjusted.

[0024] The above-mentioned clamping mechanism 12 includes a bent rod 121. The bent rod 121 is fixedly installed on the outer wall of the slider 11. By driving the first threaded rod 9 to rotate through the turntable 10, the slider 11 can drive the fixing plate 122 at the end of the bent rod 121 to move leftward. The fixing plate 122 is fixedly installed at the end of the bent rod 121. An extrusion rod 123 penetrates through the inside of the fixing plate 122. The end of the extrusion rod 123 is rotatably connected to the second clamping plate 125. By driving the second clamping plate 125 at the end of the extrusion rod 123 to move leftward through the fixing plate 122, the first clamping plate 7 and the second clamping plate 125 can clamp the middle PVC sheet. A bearing spring 124 is sleeved on the outer wall of the extrusion rod 123. One end of the bearing spring 124 is fixedly connected to the outer wall of the fixing plate 122, and the other end of the bearing spring 124 is fixedly connected to the outer wall of the extrusion rod 123. A bent plate 126 is fixedly installed on the outer wall of the fixing plate 122. An articulated block 127 is slidably connected to the outer wall of the bent plate 126. The articulated block 127 is hinged to one end of a support rod 128, and the other end of the support rod 128 is hinged to the end of the extrusion rod 123. By the extrusion force, the extrusion rod 123 extrudes the end of the support rod 128, and the articulated block 127 can drive the sleeve 129 on the bottom wall to move downward. The sleeve 129 is fixedly installed on the bottom wall of the articulated block 127. A second threaded rod 1210 is threadedly connected to the inside of the sleeve 129. By screwing the second threaded rod 1210, the height of the rubber clamping block 1211 at the bottom end can be adjusted, so that the clamping force of the first clamping plate 7 and the second clamping plate 125 on the PVC sheet is adjusted. The bottom end of the second threaded rod 1210 is fixedly installed with a rubber clamping block 1211. The rubber clamping block 1211 is located above the first threaded rod 9. By driving the rubber clamping block 1211 at the bottom end of the second threaded rod 1210 to move downward to extrude the outer wall of the first threaded rod 9 through the sleeve 129, the first threaded rod 9 can no longer continue to rotate, preventing the second clamping plate 125 from continuing to move leftward to clamp the PVC sheet, resulting in excessive clamping force.

[0025] In this embodiment, first, the turntable 10 drives the first threaded rod 9 to rotate, causing the slider 11 to drive the fixing plate 122 at the end of the bent rod 121 to move leftward. Then, the fixing plate 122 drives the second clamping plate 125 at the end of the extrusion rod 123 to move leftward. Finally, the first clamping plate 7 and the second clamping plate 125 can clamp the middle PVC sheet. At the same time, due to the extrusion force, the extrusion rod 123 moves rightward relative to the bent plate 126, so that the extrusion rod 123 extrudes the end of the support rod 128. Then, through the hinge between the support rod 128 and the hinge block 127, the hinge block 127 drives the sleeve 129 on the bottom wall to move downward. Finally, the sleeve 129 drives the rubber clamping block 1211 at the bottom end of the second threaded rod 1210 to move downward, and the rubber clamping block 1211 extrudes the outer wall of the first threaded rod 9, making the first threaded rod 9 unable to continue rotating, preventing the second clamping plate 125 from continuing to move leftward to clamp the PVC sheet with excessive clamping force. At the same time, by turning the second threaded rod 1210, the rubber clamping block 1211 at the bottom end can be adjusted in height. By adjusting the distance between the rubber clamping block 1211 and the first threaded rod 9, the extrusion degree of the extrusion rod 123 on the bearing spring 124 driven by the second clamping plate 125 can be adjusted, and the clamping force of the first clamping plate 7 and the second clamping plate 125 on the PVC sheet can be adjusted. Then, the motor 5 drives the first clamping plate 7 at the end of the rotating rod 6 to flip the middle PVC sheet, and then the spraying mechanism 3 completes the coating on it.

[0026] The above generally describes the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
