[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] As shown in Figures 1 to 4, the present invention provides a PET sheet winding machine with adjustment function, including a base plate 1, a motor 2, a winding shaft 3, and a control panel 4. The motor 2 is fixedly connected to the right side of the rear surface of the base plate 1, and the output end of the motor 2 passes through and extends out of the front side of the base plate 1. The front end of the motor 2 is fixedly connected to the winding shaft 3. The control panel 4 is fixedly connected to the left side of the rear surface of the base plate 1. A support block 5 is fixedly connected to the middle of the upper surface of the base plate 1. Two adjusting rods 6 are rotatably connected to the left side of the front surface of the base plate 1. The front ends of the adjusting rods 6 are rotatably connected to the front side of the base plate 1. The adjusting rods 6 cooperate with each other. A receiving groove 7 is opened inside the front side of the support block 5, and a limiting device 8 is placed inside the receiving groove 7.

[0023] Referring to Figure 3, the limiting device 8 includes a spring 801, a limiting rod 802, and a locking plate 803. Slide grooves 9 are provided on both the left and right sides of the top of the support block 5. The locking plate 803 is placed on the top of the support block 5. The left and right sides of the bottom of the locking plate 803 are slidably connected to the slide grooves 9. Limiting plates 10 are fixedly connected to both the left and right sides of the front surface of the locking plate 803. A number of limiting holes 11 are equidistantly provided on the surface of the limiting plates 10. Grooves 12 are provided on both the left and right sides of the receiving groove 7. A spring 801 is fixedly connected to the side of the grooves 12 that are close to each other. A limiting rod 802 is fixedly connected to the other end of each spring 801. The ends of the limiting rods 802 that are far apart from each other penetrate and extend out of the surface of the support block 5. The limiting rods 802 cooperate with the limiting holes 11.

[0024] By adopting the above solution, the limiting device 8 can stably limit the movement of materials of different widths, effectively preventing deviation during the winding process and ensuring the winding quality.

[0025] Referring to Figure 3, the ends of the limiting rods 802 that are close to each other pass through the groove 12 and extend into the receiving groove 7. The sides of the limiting rods 802 that are close to each other are fixedly connected to sliders 13. The receiving groove 7 is filled with a pressing plate 14, which is slidably connected to the receiving groove 7. The left and right sides of the front surface of the pressing plate 14 are provided with limiting grooves 15, which are all at a certain angle. The sliders 13 are slidably connected to the inside of the limiting grooves 15.

[0026] By adopting the above solution, the position of the limit rod 802 can be conveniently adjusted and locked by setting the pressing plate 14 and the limiting groove 15, which simplifies the operation process and improves work efficiency.

[0027] Referring to Figure 1, a movable groove 16 is provided on the right side of the upper surface of the base plate 1. A screw 17 is rotatably connected to the rear side of the movable groove 16. The front end of the screw 17 passes through and extends out of the front side of the base plate 1. A rotating handle 18 is fixedly connected to the front end of the screw 17. A movable plate 19 is placed on the top of the base plate 1. The bottom of the movable plate 19 is threaded to the surface of the screw 17. A fixed groove 20 is provided on the top of the movable plate 19. A first support plate 21 is slidably connected inside the fixed groove 20.

[0028] By adopting the above solution, the position of the first support plate 21 can be precisely adjusted by setting the screw 17. At the same time, the winding range can be flexibly changed according to the width of the material to ensure that the material remains centered during the winding process, effectively avoiding winding deviation.

[0029] Referring to Figures 3 and 4, a number of fixing holes 22 are equidistantly provided on the rear side of the movable plate 19. A placement groove 23 is provided at the bottom of the first support plate 21. A compression spring 24 is fixedly connected to the front side of the placement groove 23. A locking rod 25 is fixedly connected to the other end of the compression spring 24. The rear ends of the locking rods 25 all penetrate through and extend out of the first support plate 21. The locking rods 25 are used in conjunction with the fixing holes 22. A pull rod 26 is fixedly connected to the front end of the locking rod 25. The front end of the pull rod 26 penetrates through and extends out of the front side of the first support plate 21.

[0030] By adopting the above solution, the position of the first support plate 21 can be quickly lowered by setting the fixing hole 22 and the clamping rod 25, providing sufficient space for removing the wound material and avoiding inconvenience or potential safety risks caused by the support plate being too high.

[0031] Referring to Figure 4, a second support plate 27 is hinged to the top left side of the first support plate 21. Both the first support plate 21 and the second support plate 27 are used in conjunction with the winding shaft 3. A baffle 30 is hinged to the right side of the second support plate 27. A baffle groove 31 is provided on the surface of the baffle 30. A limit block 28 is rotatably connected to the right side of the first support plate 21. The limit block 28 is used in conjunction with the baffle groove 31.

[0032] By adopting the above solution, the position of the second support plate 27 can be locked by setting the limit block 28 and the stop groove 31, effectively preventing it from opening accidentally during the winding process.

[0033] Referring to Figure 1, stabilizing grooves 29 are provided on the left and right sides of the top of the base plate 1, and the left and right sides of the bottom of the movable plate 19 are slidably connected to the inside of the two stabilizing grooves 29.

[0034] By adopting the above solution, the stability of the moving plate 19 during the adjustment process can be enhanced by setting the stabilizing groove 29, preventing it from shaking or shifting during the movement.

[0035] The working principle of this utility model:

[0036] In use, first align the limiting block 28 and the stop groove 31, then open the second support plate 27. Next, pull the pull rod 26 forward to move the locking rod 25 out of the fixing hole 22. At this time, move the first support plate 21 downward, then place the drum core onto the take-up shaft 3. Then move the first support plate 21 upward, and then release the pull rod 26. The compression spring 24 will reset the locking rod 25, thus fixing the first support plate 21. Then close the second support plate 27, and then let the material pass through the two adjusting rods 6 and be fixed on the drum core. At this time, adjust the moving plate according to the width of the material. At position 19, rotate screw 17 to move moving plate 19 along stabilizing groove 29 to a suitable position. Then adjust the position of clamping plate 803. First, press down on pressing plate 14. At this time, slider 13 will move along limiting groove 15, driving the limiting rods 802 on both sides to move out of limiting hole 11. Then pull limiting plate 10 to adjust clamping plate 803 to a suitable position. After releasing pressing plate 14, spring 801 will reset limiting rod 802 and insert it back into limiting hole 11, thereby fixing clamping plate 803. At this time, the entire equipment adjustment is completed. Start motor 2 to carry out subsequent winding work.

[0037] In summary, this PET sheet winding machine with adjustment function solves the problem of insufficient flexibility and precision in the adjustment mechanism of existing equipment when processing PET sheets of varying widths. This is achieved through the coordinated use of a base plate 1, motor 2, winding shaft 3, control panel 4, support block 5, adjustment rod 6, receiving groove 7, limiting device 8, slide groove 9, limiting plate 10, limiting hole 11, groove 12, slider 13, pressing plate 14, limiting groove 15, moving groove 16, screw 17, rotating handle 18, moving plate 19, fixing groove 20, first support plate 21, fixing hole 22, placement groove 23, compression spring 24, clamping rod 25, pull rod 26, second support plate 27, limiting block 28, stabilizing groove 29, baffle 30, and baffle groove 31. This not only limits the adaptability of the equipment to different specifications of materials but also easily causes material deviation during the winding process, seriously affecting the quality and efficiency of winding, which may lead to a decrease in yield and an increase in production costs.
