[0002] In the modern plastics processing industry, the winding process of plastic sheets is a crucial step. As a material widely used in packaging, construction, electronics, and automotive industries, the production and post-processing of plastic sheets directly impact product quality and performance. The winding process is not only the final step in the plastic sheet production line but also a vital component of material storage and transportation. Therefore, ensuring the stability and consistency of plastic sheets during the winding process is of great significance for improving production efficiency and reducing costs.

[0003] Currently, traditional winding equipment often suffers from inaccurate tension control, which leads to the loosening or bending of plastic sheets during the winding process, thus affecting the appearance and performance of the material. This phenomenon not only increases production costs but may also lead to material waste, negatively impacting the economic benefits of enterprises. Therefore, a tension adjustment device for plastic sheet winding is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0031] Reference Figures 1-3This utility model provides an embodiment of a tension adjustment device for winding plastic sheets, comprising a body 1, which serves as the supporting frame for the entire device and has a robust structure to withstand various forces generated during operation. A take-up roller 4 is rotatably connected to the middle of the body 1, which is used to wind the plastic sheet into a roll. A second sprocket 6 is fixedly connected to the left side of the take-up roller 4, which is used for power transmission. A motor 2 is fixedly connected to the left side of the body 1, which is the power source for the entire device. A first sprocket 3 is fixedly connected to the output end of the motor 2. A chain 5 is sleeved between the first sprocket 3 and the second sprocket 6, which transmits the rotation of the motor 2 to the take-up roller 4. Multiple 17s are rotatably connected to the middle of the body 1, which are used to guide the wound plastic sheet. Adjustment components are installed on both the left and right sides of the body 1 to precisely adjust the tension as needed. An extrusion component is installed on the upper side of the take-up roller 4, which applies appropriate pressure to the wound plastic sheet to ensure its shape and quality during the winding process.

[0032] Reference Figure 3 and Figure 4 The adjustment assembly includes two cylinders 7, which are fixedly connected to the outside of the machine body 1 on opposite sides. The two cylinders 7 are fixedly connected to the outside of the machine body 1 to provide the necessary pneumatic power to adjust the tension. The output end of the cylinder 7 is rotatably connected to a connecting rod 8, and the end of the connecting rod 8 away from the cylinder 7 is rotatably connected to a slider 9, so that the slider 9 can move linearly under the push of the cylinder 7. An adjustment roller 10 is rotatably connected between the two sliders 9. The rotation and movement of 10 can directly affect the tension of the plastic sheet, thereby achieving precise control of the winding process.

[0033] Reference Figure 1 , Figure 3 and Figure 5 The extrusion assembly includes a mounting plate 12. The left and right sides of the mounting plate 12 are fixedly connected to the upper side of the machine body 1 by mounting brackets to ensure the stability and reliability of the mounting plate 12. A slide plate 13 is slidably connected inside the mounting plate 12. The slide plate 13 can move freely within the mounting plate 12 to adapt to different working conditions. Multiple springs 14 are fixedly connected to the upper side of the slide plate 13. The springs 14 provide necessary elastic support and can adjust the pressure applied to the plastic sheet as needed. Multiple slide rods 15 are fixedly connected to the bottom of the slide plate 13. The slide rods 15 are used to fix the pressure plate 16 and drive the pressure plate 16 to slide by sliding themselves. The pressure plate 16 is fixedly connected to the bottom of the slide rods 15. The pressure plate 16 contacts the plastic sheet and plays a pressing role.

[0034] Reference Figure 1 and Figure 2A control box is installed on the rear right side of the machine body 1. The control box is used to centrally manage and control the operation of the entire tension adjustment device, including the starting and stopping of the motor and the adjustment of tension. Storage boxes are installed on the front left and right sides of the machine body 1. The storage boxes are used to store the plastic sheet rolls and other related materials generated during the winding process, which facilitates the management and use of materials by the operators.

[0035] Reference Figure 4 Two limiting rods 11 are fixedly connected to the inner walls on both the left and right sides of the machine body 1. The function of the limiting rods 11 is to limit the movement range of the slider 9 and ensure its stability and safety during operation. The slider 9 is internally slidably connected to the outside of the limiting rods 11, so that the slider 9 will not leave its predetermined track when it moves, thereby improving the reliability of the device.

[0036] Reference Figure 5 The end of the spring 14 away from the slide plate 13 is fixedly connected to the upper side of the inner wall of the mounting plate 12 to ensure that the spring 14 can provide continuous support force during operation. The outer side of the slide rod 15 is slidably connected to the bottom of the mounting plate 12 to ensure the smooth movement of the slide rod 15 and to allow the slide plate 13 to move freely up and down according to the elastic force of the spring 14, thereby realizing the dynamic adjustment of the pressing force.

[0037] Reference Figures 1-3 The pressure plate 16 and the outer side of the winding roller 4 are closely fitted to ensure that the pressure plate 16 can apply pressure evenly to the plastic sheet during the winding process, preventing the material from bending or being damaged.

[0038] Reference Figure 5 The pressure plate 16 is arc-shaped, which can better adapt to the shape of the winding roller 4 and provide a uniform pressure distribution. The pressure plate 16 is made of soft rubber, which has good elasticity and grip, effectively reducing damage to the plastic sheet, while providing the necessary friction to ensure the stability and safety of the material during the winding process.

[0039] Working principle: When it is necessary to wind up the plastic sheet, the plastic sheet to be wound is wrapped around the outside of the winding roller 4. The motor 2 is controlled by the control box to operate. The motor 2 drives the first sprocket 3 to rotate, which in turn drives the chain 5 to rotate, which in turn drives the second sprocket 6 to rotate, causing the winding roller 4 to rotate and wind up the plastic sheet. During the winding process, the mounting plate 12 presses down on the wound plastic sheet. Since the winding roller 4 is always in the winding state, the diameter of the winding roller 4 changes, causing the pressure plate 16 to slide upward, which in turn drives the slide bar 15 to slide upward, causing the slide plate 13 to slide upward. The spring 14 is compressed, and since the spring 14 is elastic, it will reset, pushing the slide plate 13 downwards. This further drives the pressure plate 16 downwards, so that the plastic sheet is pressed against the outer side of the winding roller 4 by the pressure plate 16 during the winding process. This allows the plastic sheet to fit tightly against the inner surface of the winding roller 4. During the winding process, when the plastic sheet becomes loose or tight, the cylinder 7 is controlled by the control box to operate. The operation of the cylinder 7 drives the connecting rod 8 to slide, which in turn drives the slider 9 to slide. This causes the adjusting roller 10 between the two sliders 9 to slide up and down, thereby adjusting the tension of the plastic sheet during winding.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
