Description

Technical Field

[0001] This utility model relates to a PVC strip winding cage, belonging to the field of PVC strip technology. Background Technology

[0002] PVC winding machines are plastic machinery equipment that have been developed in China in recent years. Large-diameter PVC pipes produced by PVC winding machines have been widely used in municipal sewage, coal mine ventilation, etc.

[0003] A search revealed a single-walled PVC strip winding cage with adjustable radius, disclosed in patent number "CN212268953U". The cage includes a front flange on which at least one set of strip winding drive components is mounted. Each drive component comprises a support plate, an outer drive roller, and an inner drive roller. The outer drive roller is mounted on the support plate via a motor. A first push rod and a second push rod are cross-connected; pushing and pulling the first and second push rods causes a dovetail slider to move the inner drive roller up and down, allowing for fine-tuning of the distance between the outer and inner drive rollers. This design is suitable for winding PVC strips of varying thicknesses and has a wide range of applications.

[0004] The above-mentioned method uses a moving component to control the fine adjustment of the distance between the inner and outer drive rollers to adapt to the winding of PVC strips of different thicknesses. However, the outer and inner drive rollers are fixedly installed with the front flange. When the drive rollers are damaged and need to be replaced, disassembly and replacement are inconvenient, which affects the efficiency of drive roller replacement. Therefore, we have designed a PVC strip winding cage. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a PVC sheet and strip winding cage:

[0023] according to Figure 1-4 As shown, the device includes a base 1, a front flange 2 fixedly mounted on the top of the base 1, a matching rear flange 4 connected to the back of the front flange 2 via an auxiliary roller 3, mounting plates 5 on both sides of the front of the front flange 2, a clamping assembly between the mounting plates 5 and the front flange 2, connecting posts 16 fixedly mounted at the four corners of the front of the mounting plates 5, and fixing plates 17 fixedly mounted at the ends of the four connecting posts 16, with two drive rollers 22 slidably mounted on the surface of the fixing plates 17.

[0024] Specifically, the clamping assembly facilitates the installation and removal of the drive roller 22, replacing the traditional fixed installation of the drive roller 22 and making it easier to replace the drive roller 22.

[0025] according to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model discloses a PVC strip winding cage. The clamping assembly includes two clamping blocks 6. The two clamping blocks 6 are slidably connected to both sides of the back of the mounting plate 5. Positioning posts 11 are fixedly provided on the sides of both clamping blocks 6. Positioning holes are opened on the outer and inner walls of the front flange 2. The positioning posts 11 are nested and connected with the corresponding positioning holes.

[0026] The mounting plate 5 has first sliding grooves 12 on both sides of its back. Sliding rods 13 are fixedly installed on both sides of the inner wall of the two first sliding grooves 12. First sliders 14 are slidably connected to the surface of the sliding rods 13. The front of the first sliders 14 is fixedly connected to the side of the corresponding clamping block 6. A compression spring 15 is nested at one end of the two sliding rods 13. One end of the compression spring 15 is fixedly connected to the groove wall of the first sliding groove 12, and the other end of the compression spring 15 is fixedly connected to the side of the first slider 14.

[0027] The top of each of the two first sliding grooves 12 is provided with a through groove that communicates with the outside. A push block 7 is slidably connected inside the through groove, and the bottom end of the push block 7 is fixedly connected to the top end of the first slider 14.

[0028] Specifically, the compression spring 15 and the push block 7 work together to move the first slider 14. The movement of the first slider 14 drives the movement of the clamping block 6. The clamping block 6 can quickly clamp and fix the mounting plate 5 to the front flange 2, which facilitates the installation and removal of the drive roller 22 and the front flange 2.

[0029] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a PVC strip winding cage. A through groove is provided at the center of the fixing plate 17. A second sliding groove 20 is provided at the bottom of the through groove. A second slider is slidably connected inside the two second sliding grooves 20. An mounting block 19 is fixedly installed at the top of the second slider. A drive roller 22 is rotatably connected to the center of the mounting block 19. A drive motor 18 is fixedly installed on the back of the mounting block 19. The output shaft of the drive motor 18 is fixedly connected to one end of the drive roller 22.

[0030] Both sides of the inner wall of the second slide groove 20 are rotatably connected to positive and negative lead screws 21. The two ends of the positive and negative lead screws 21 are threadedly connected to the center of the corresponding second slider. One end of the positive and negative lead screws 21 passes through the second slide groove 20 and is fixedly installed with a rotating block.

[0031] Specifically, the rotating block drives the positive and negative lead screws 21 to rotate, which in turn drives the two second sliders to move. The movement of the second sliders drives the drive rollers 22 to move. The movement of the drive rollers 22 can adjust the distance between the two drive rollers 22, thus adapting to the winding of PVC strips of different thicknesses.

[0032] according to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a PVC strip winding cage. Support blocks 8 are fixedly installed at the corners on both sides of the base 1. Threaded push rods 9 are threadedly connected to the top of the two support blocks 8. One end of the threaded push rod 9 is rotatably connected to a limit plate 10. The two limit plates 10 are in contact with the outer wall of the rear flange 4.

[0033] Specifically, the threaded push rod 9 pushes the limiting plate 10 to contact the rear flange 4, which facilitates the limiting and fixing of the winding cage.

[0034] Working principle: This utility model is a PVC strip winding cage. When using this PVC strip winding cage to wind PVC sheets, firstly, the installation between the drive roller 22 and the front flange 2 is manually performed. Two clamping blocks 6 are pushed to both sides. At this time, the compression spring 15 on the surface of the slide rod 13 is under pressure, and the two clamping blocks 6 are nested with the front flange 2. Then, the clamping blocks 6 are manually released, and the compression spring 15 compresses the first slider 14 to move. The first slider 14 drives the clamping blocks 6 to move and reset, so that the positioning post 11 on the side of the clamping block 6 is nested with the positioning hole, which facilitates the assembly of the drive roller 22.

[0035] Next, adjust the distance between the two drive rollers 22, manually rotate the rotating block, and drive the positive and negative screws 21 to rotate. The positive and negative screws 21 drive the two second sliders to separate or move towards the center. The movement of the second sliders drives the mounting block 19 to move. The movement of the mounting block 19 drives the drive rollers 22 to move, thereby adjusting the distance between the two drive rollers 22 to adapt to the thickness of the PVC strip.
