Technical Field
[0001] This utility model belongs to the technical field of plastic sheet winding equipment, and particularly relates to a plastic sheet material winding machine. Background Technology
[0002] In the field of plastic sheet production, plastic sheet winding machines, as key supporting equipment for plastic sheet extruders, are required to handle continuous plastic sheets produced by the extrusion process, guiding and traction them before winding them into large-diameter, ultra-heavy rolls. While these large rolls can reduce the frequency of feeding into subsequent forming machines, the operational efficiency of unloading after winding and changing the winding rollers, as well as whether continuous operation is possible, directly affects the overall production process. They are widely used in industries such as packaging and building materials that rely on subsequent forming processes. While existing plastic sheet material winding machines achieve automated continuous winding and reduce sheet breakage through basic tension adjustment, meeting the winding needs of conventional and large-size rolls, the operation of feeding and winding roller replacement is cumbersome and time-consuming for large-diameter and heavy rolls. Therefore, we propose a new plastic sheet material winding machine. Utility Model Content

The dual-drive structure can operate alternately through the matching independent winding structure, so that the normal operation of the equipment is not interrupted during unloading. The convenient unloading structure can improve the ease of unloading operation of the winding structure. In this technical solution, the combination of a dual-drive structure, an independent winding structure, and a convenient unloading structure ensures continuous operation of the winding machine and improves unloading efficiency. In the above technical solution, further, two symmetrically distributed reducers are fixedly installed at the bottom of the equipment mounting frame, each reducer is equipped with a motor, and the output shafts of the two reducers are fixedly installed with a first sprocket. In this technical solution, the motor and the reducer work together to drive the first sprocket to rotate, providing stable power for the dual-drive structure. In the above technical solution, further, two sets of symmetrically distributed first bearings are fixedly installed on the upper part of the equipment mounting frame. In each set of first bearings, two corresponding first bearings are rotatably connected to a drive shaft. The outer surfaces of the two drive shafts are fixedly installed with second sprockets. In this technical solution, the first bearing supports the stable rotation of the drive shaft, and the second sprocket is used to receive and transmit power. In the above technical solution, furthermore, chains are mounted on the teeth of both second sprockets, and the ends of the two chains away from the second sprockets are respectively mounted on the teeth of the two first sprockets, so that the two second sprockets are respectively connected to the two first sprockets through corresponding chains; universal couplings are fixedly installed at the rear ends of both drive shafts. In this technical solution, the chain enables power transmission, and the universal coupling compensates for installation angle deviations to ensure transmission stability. In the above technical solution, a guide roller frame is fixedly installed above the equipment mounting frame, and two aluminum guide rollers are rotatably installed on the guide roller frame; a support plate is also fixedly installed on the upper part of the equipment mounting frame, and two buffer members are provided on the rear side of the upper surface of the support plate. A support frame is fixedly installed above the two buffer members, and the two support frames are rotatably connected to two universal couplings respectively.
[0005] In this technical solution, aluminum guide rollers guide the plastic sheet, and buffer components and support frames work together to protect the universal coupling. In the above technical solution, further, a guide rail frame is fixedly installed at the bottom of the rear side of the equipment mounting frame, and two sets of guide rails are fixedly installed above the guide rail frame.

The bottom of each set of casters is inserted into the guide rail groove of the corresponding set of guide rails. In this technical solution, the guide rail and casters work together to guide the winding frame, and the wide-angle structure facilitates the winding frame entering the guide rail. In the above technical solution, further, two symmetrically distributed second bearings are fixedly installed on the top of each of the two winding frames. In each group of second bearings, the two second bearings are rotatably connected to a winding shaft. The two winding shafts are respectively arranged corresponding to two aluminum guide rollers.

In this technical solution, the second bearing supports the rotation of the take-up shaft, and the joint cooperates with the universal coupling to transmit power to the take-up shaft.
[0006] The beneficial effects of this utility model are: 1.

[0011] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.
[0012] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0013] Example 1: This example provides a plastic sheet material winding machine, including a machine mounting frame 1. A dual drive structure is provided on the top of the machine mounting frame 1. Each of the dual drive structures is equipped with an independent winding structure on its rear side, and the winding structure is equipped with a convenient unloading structure. The dual-drive structure can operate alternately with the matching independent winding structure, so that the normal operation of the equipment is not interrupted during unloading. The convenient unloading structure can improve the ease of unloading operation of the winding structure. In this embodiment, the combination of a dual-drive structure and an independent winding structure directly solves the problem of existing single-station winding machines requiring machine stoppage for unloading, enabling simultaneous winding and unloading, and effectively improving production efficiency. From the working principle perspective, the dual-drive structure can provide power support for two sets of independent winding structures. When one set of winding structures completes winding and unloads material through the convenient unloading structure consisting of the subsequent guide rail frame 15, guide rail 16, winding frame 17, casters 18, etc., the other set of winding structures can immediately start winding operations, ensuring continuous operation of the equipment, avoiding production interruptions due to machine stoppages, and reducing the hassle of frequent material loading for subsequent forming machines, thus reducing material waste. Example 2: This example provides a plastic sheet material winding machine. In addition to the technical solutions of the above examples, it also has the following technical features: two symmetrically distributed reducers 2 are fixedly installed at the bottom of the equipment mounting frame 1. Each reducer 2 is equipped with a motor 3, and the output shafts of the two reducers 2 are fixedly installed with a first sprocket 4. The combination of motor 3 and reducer 2 provides stable and suitable power for the dual-drive structure, avoiding problems such as unstable winding speed and sheet breakage caused by excessive or insufficient power, thus improving winding quality. Its working principle is that after the motor 3 starts, it outputs power, which is reduced and adjusted by reducer 2, driving the first sprocket 4 on the output shaft to rotate. This lays the foundation for the subsequent transmission structure such as chain 8 and second sprocket 7 to transmit power, ensuring that the dual-drive structure can obtain continuous and stable power input, and adapting to the winding requirements of large-diameter and ultra-heavy rolls. Example 3: This example provides a plastic sheet material winding machine. In addition to the technical solutions of the above examples, it also has the following technical features: two sets of symmetrically distributed first bearings 5 are fixedly installed on the upper part of the equipment mounting frame 1. In each set of first bearings 5, two corresponding first bearings 5 are rotatably connected to a drive shaft 6. The outer surfaces of the two drive shafts 6 are fixedly installed with second sprockets 7.
[0014] The first bearing 5 supports the drive shaft 6, reducing frictional resistance during rotation and preventing transmission deviation due to wobbling, thus ensuring transmission stability. The second sprocket 7, as an intermediate component for power transmission, accurately receives the power transmitted by the first sprocket 4 and transmits it to the drive shaft 6. In terms of working principle, the two sets of first bearings 5 respectively position and support the two drive shafts 6, enabling them to rotate stably. The second sprocket 7, fixed on the drive shaft 6, receives the power transmitted by the first sprocket 4 through cooperation with the chain 8, preparing for the subsequent power transmission by the universal coupling 9. Example 4: This example provides a plastic sheet material winding machine. In addition to the technical solutions of the above examples, it also has the following technical features: chains 8 are mounted on the teeth of the two second sprockets 7, and the ends of the two chains 8 away from the second sprockets 7 are respectively mounted on the teeth of the two first sprockets 4, so that the two second sprockets 7 are respectively connected to the two first sprockets 4 through the corresponding chains 8; universal couplings 9 are fixedly installed at the rear ends of the two drive shafts 6. The chain 8 connects the first sprocket 4 and the second sprocket 7, enabling efficient and smooth power transmission and avoiding power loss. The universal coupling 9 compensates for the installation angle deviation between the drive shaft 6 and the subsequent take-up shaft 20, preventing jamming and component damage during transmission and extending the service life of the transmission system. The working principle is that when the first sprocket 4 rotates, the chain 8 drives the second sprocket 7 to rotate synchronously. The second sprocket 7 drives the drive shaft 6 to rotate within the first bearing 5. The universal coupling 9 at the rear end of the drive shaft 6 then transmits power to the take-up shaft 20, ensuring that power can be stably transmitted to the take-up structure. Example 5: This example provides a plastic sheet material winding machine. In addition to the technical solutions of the above examples, it also has the following technical features: a guide roller frame 10 is fixedly installed above the equipment mounting frame 1, and two aluminum guide rollers 11 are rotatably installed on the guide roller frame 10; a support plate 13 is also fixedly installed on the upper part of the equipment mounting frame 1, and two buffer members 14 are provided on the rear side of the upper surface of the support plate 13. Support frames are fixedly installed above the two buffer members 14 respectively, and the two support frames are rotatably connected to two universal couplings 9 respectively. Among them, the aluminum guide roller 11 can accurately guide the plastic sheet, prevent the sheet from shifting or wrinkling during the winding process, and improve the flatness of the roll. The buffer 14, together with the support frame, can alleviate the vibration generated during the transmission of the universal coupling 9, avoid the vibration causing the universal coupling 9 to become loose from other components, and protect the universal coupling 9, extending its service life. The working principle is that after the plastic sheet is guided by the aluminum guide roller 11, it can smoothly enter the winding structure, while the buffer 14 on the support plate 13 provides auxiliary support for the universal coupling 9 through the support frame, reducing the shaking of the universal coupling 9 during power transmission and ensuring stable transmission. Example 6: This example provides a plastic sheet material winding machine. In addition to the technical solutions of the above examples, it also has the following technical features: a guide rail frame 15 is fixedly installed at the bottom of the rear side of the equipment mounting frame 1. Two sets of guide rails 16 are fixedly installed above the guide rail frame 15. The entrance of each set of guide rails 16 is provided with an outwardly inclined wide-angle structure. A winding frame 17 is provided above each set of guide rails 16. Two sets of casters 18 are fixedly installed at the bottom of each of the two winding frames 17, and the bottom of each set of casters 18 is inserted into the guide rail groove of the corresponding set of guide rails 16. The combination of casters 18 and guide rails 16 allows the winding frame 17 to move smoothly along the guide rails 16, enabling convenient unloading of large-diameter, heavy-duty rolls and solving the problem of cumbersome roll changing during unloading in the technical background. The wide-angle structure at the entrance of the guide rails 16 guides the winding frame 17 to accurately enter the guide rails 16, avoiding operational delays caused by difficulty in aligning the winding frame 17. The working principle is that after the winding structure completes winding, the operator can push the winding frame 17, causing the casters 18 at the bottom of the winding frame 17 to move along the guide rails 16 on the guide rail frame 15. The wide-angle structure assists the winding frame 17 in quickly aligning with the guide rails 16, easily completing the unloading operation and improving unloading efficiency. Example 7: This example provides a plastic sheet material winding machine. In addition to the technical solutions of the above examples, it also has the following technical features: two symmetrically distributed second bearings 19 are fixedly installed on the top of each of the two winding frames 17. In each group of second bearings 19, the two second bearings 19 are rotatably connected to a winding shaft 20. The two winding shafts 20 are respectively arranged corresponding to two aluminum guide rollers 11. The front ends of the two winding shafts 20 are fixedly installed with connectors 12. The two connectors 12 are respectively fixedly connected to two universal couplings 9 by pins. The second bearing 19 supports the take-up shaft 20, reducing friction during rotation and ensuring stable rotation of the material roll, thus improving winding quality. The connector 12 is fixedly connected to the universal coupling 9 via a pin, ensuring stable power transmission to the take-up shaft 20 and facilitating quick disassembly of the pin after winding, thus releasing the connection between the connector 12 and the universal coupling 9. This allows for convenient roller replacement in conjunction with the movement of the take-up frame 17. The working principle is as follows: the universal coupling 9 connects to the take-up shaft 20 via the connector 12, transmitting power to the take-up shaft 20. Supported by the second bearing 19, the take-up shaft 20 rotates stably, winding the plastic sheet guided by the aluminum guide roller 11. After winding, removing the pin allows the take-up frame 17 to unload the material. Simultaneously, another set of take-up shafts 20 connects to the universal coupling 9 via the connector 12 to continue winding operations.
[0015] Working principle: After the motor 3 starts, it drives the matching reducer 2 to run. The first sprocket 4 on the output shaft of the reducer 2 drives the second sprocket 7 on the upper part of the equipment mounting frame 1 to rotate through the chain 8. The second sprocket 7 drives the transmission shaft 6 fixed thereto to rotate stably in the first bearing 5. The universal coupling 9 at the rear end of the transmission shaft 6 is fixedly connected to the connector 12 at the front end of the take-up shaft 20, transmitting power to the take-up shaft 20. The take-up shaft 20 is mounted on the top of the take-up frame 17 through the second bearing 19. At the same time, the plastic sheet is guided by the aluminum guide roller 11 on the guide roller frame 10 and then wound onto the take-up shaft 20 to complete the winding. When one set of winding structures completes winding, the connection between the connector 12 and the universal coupling 9 is released. The take-up frame 17 moves along the guide rail 16 on the guide rail frame 15 through the bottom casters 18 to facilitate material unloading. At this time, the other set of winding structures continues to operate under the drive of the dual drive structure to ensure continuous operation of the equipment.
