Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing technology, and in particular to a plastic strip winding device. Background Technology
[0002] Plastic strips are typically produced continuously through processes such as extrusion molding, resulting in a linear and uninterrupted output. In the production and processing of plastic strips, winding is a crucial step. Winding devices use winding rollers to coil the continuously produced plastic strips into rolls, ensuring neat storage and facilitating subsequent handling and transportation.
[0003] Existing technology, such as the utility model patent document with authorization announcement number "CN223032676U" and patent name "A High-Tightness Winding Device for Plastic Rattan", discloses a winding device. The device includes a mounting frame, a winding roller rotatably connected inside the mounting frame, a clamping roller rotatably connected to one side of the mounting frame, two clamping rollers arranged vertically, a gear fixedly connected to the front of each clamping roller, a first pulley fixedly connected to the front of one gear, a transmission belt installed on the first pulley, a second pulley installed on one side of the transmission belt, and a reciprocating screw fixedly connected to the rear of the second pulley.
[0004] However, the winding device in the aforementioned patent documents only has a single winding function and lacks a corresponding structure for workers to package the wound plastic rolls. This leads to a situation where, in actual operation, when workers remove the wound plastic rolls from the winding rollers, the rolls are prone to loosening and unraveling due to the lack of immediate fixing or packaging constraints. Once the rolls unravel, it not only disrupts the regular shape of the plastic strips, increasing the workload of subsequent processing, but may also cause the plastic strips to become entangled and squeezed, resulting in surface wear or structural deformation, affecting product quality. At the same time, the unraveled plastic strips also cause inconvenience for subsequent handling, storage, and reprocessing, reducing overall production efficiency.
[0005] Therefore, in view of the above-mentioned defects of existing winding devices, it is necessary to develop a plastic strip winding device that can solve the problem of plastic rolls easily unraveling after winding. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the present invention provides a plastic strip winding device to solve the technical problem mentioned in the background technology that the winding device only has a single winding function and lacks a corresponding structure for workers to package the wound plastic roll.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A plastic strip winding device includes an operating table with a drive assembly on the operating table. The output end of the drive assembly is connected to a transmission shaft. A winding roller is fixedly mounted on the outer periphery of the transmission shaft. The winding roller is parallel to the operating table and positioned above it. An operating groove is formed on the outer surface of the winding roller along its length. A first baffle is fixedly mounted on the outer periphery of the transmission shaft and is fixedly connected to one end face of the winding roller. A second baffle is horizontally slidably connected to the outer periphery of the winding roller. Both the first and second baffles have through grooves that communicate with the operating groove on the winding roller. A guide assembly is also provided on the operating table, positioned on one side of the winding roller. The guide assembly is used to clamp the plastic strip. The guide assembly is connected to the transmission shaft, and when the drive assembly drives the transmission shaft to rotate, it can move the guide assembly back and forth along the length of the winding roller.
[0008] Working principle: Before use, move the position of the second baffle. During use, mount one end of the plastic strip onto the take-up roller via the guide assembly. Then, activate the drive assembly, which drives the transmission shaft to rotate. The rotation of the transmission shaft also causes the guide assembly to move back and forth along the length of the take-up roller, ensuring the plastic strip is evenly wound onto it. After one batch of plastic strips is wound, use a plastic constraint strip to package and constrain the roll material by passing it through the grooves on the second baffle, the operating groove on the take-up roller, and the groove on the first baffle. Finally, remove the packaged roll material from the take-up roller for the next batch of winding.
[0009] Beneficial effects: 1. An operating groove is provided along the length of the outer surface of the take-up roller. Both the first and second baffles have through grooves, and both through grooves communicate with the operating groove on the take-up roller. This structural design allows workers to use plastic restraint strips to package and restrain the roll material by passing through the through grooves on the second baffle, the operating groove on the take-up roller, and the through groove on the first baffle after a batch of plastic strips has been wound. This allows for timely packaging and restraint of the roll material, preventing it from unraveling when removed from the take-up roller. This not only maintains the neat shape of the plastic strips, reducing subsequent processing work, but also prevents the plastic strips from tangling and being squeezed, effectively avoiding surface wear or structural deformation, thus significantly improving product quality. Furthermore, the entire operation is simple and direct, requiring no additional complex steps to effectively fix the roll material, greatly improving work efficiency. 2. The guide assembly is connected to the drive shaft. When the drive assembly drives the drive shaft to rotate, the rotation of the drive shaft can drive the guide assembly to move back and forth along the length of the take-up roller. This design achieves uniform distribution and winding of the plastic strip on the take-up roller, eliminating the need for manual adjustment of the plastic strip's position, improving the automation level of the winding process, and further enhancing work efficiency.
[0010] 3. A second baffle is horizontally slidably connected to the outer periphery of the winding roller. By moving the position of the second baffle, the winding width can be adjusted according to different production needs, thus making it suitable for winding plastic strips of different specifications and expanding the applicability of the device.

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0014] Example: like Figures 1-3 As shown, a plastic strip winding device includes an operating table 1, on which a drive assembly is mounted. The output end of the drive assembly is connected to a transmission shaft 2. A winding roller 3 is fixedly mounted on the outer periphery of the transmission shaft 2. The winding roller 3 is parallel to and positioned above the operating table 1. An operating groove 4 is provided on the outer surface of the winding roller 3 along its length. A first baffle 5 is fixedly mounted on the outer periphery of the transmission shaft 2, and the first baffle 5 is fixedly connected to one end face of the winding roller 3. A second baffle 6 is horizontally slidably connected to the outer periphery of the winding roller 3. The second baffle 6 is locked to the take-up roller 3 by bolts. The first baffle 5 and the second baffle 6 are both provided with grooves 7, and both grooves 7 are connected to the operating grooves 4 on the take-up roller 3. The operating table 1 is also provided with a guide assembly, which is located on one side of the take-up roller 3 and is used to clamp the plastic strip. The guide assembly is connected to the drive shaft 2. When the drive assembly drives the drive shaft 2 to rotate, it can drive the guide assembly to move back and forth along the length of the take-up roller 3.
[0015] like Figure 1 and Figure 2 As shown, the drive assembly includes a motor 8, which is mounted on the operating table 1 via a fixing block. The drive shaft 2 is connected to the output end of the motor 8. A first mounting plate 9 is also fixed on the operating table 1. The drive shaft 2 rotatably passes through the first mounting plate 9 via bearings. The first mounting plate 9 supports the drive shaft 2. It should be noted that the method of rotation via bearings is existing technology, and those skilled in the art should understand its structure, principle, and usage; therefore, it will not be described in detail here. This structure achieves the rotation of the take-up roller 3 by driving the motor 8, which is mechanized and automated, and easy to operate.
[0016] like Figures 1-3 As shown, a gear 10 is fixed to the outer periphery of the rod segment of the drive shaft 2 located between the motor 8 and the first mounting plate 9; two second mounting plates 11 are also fixed on the operating table 1, and a first rotating shaft 12 is rotatably connected between the two second mounting plates 11 through a bearing. The first rotating shaft 12 is parallel to the take-up roller 3, and a gear 10 is also fixed to the outer periphery of the end of the first rotating shaft 12. A rack 13 meshes between the two gears 10, and the rack 13 enables the two gears 10 to rotate simultaneously, thereby achieving the effect of simultaneous rotation of the drive shaft 2 and the first rotating shaft 12, saving power resources; the guide assembly is connected to the first rotating shaft 12.
[0017] like Figure 1 and Figure 3 As shown, the guide assembly includes a first horizontal moving block 141, a second horizontal moving block 142 disposed below the first horizontal moving block 141, and a mounting bracket 143 fixed between the first horizontal moving block 141 and the second horizontal moving block 142. The first rotating shaft 12 is a reciprocating lead screw, and the first horizontal moving block 141 is threadedly connected to the first rotating shaft 12. A first limiting rod 15 parallel to the first rotating shaft 12 is fixed between the two second mounting plates 11. The first limiting rod 15 is a smooth round rod, and the second horizontal moving block 142 is slidably connected to the first limiting rod 15. The setting of the first limiting rod 15 plays a limiting role in the movement of the guide assembly, so that the guide assembly can reciprocate along the length direction of the first rotating shaft 12, and prevent the guide assembly from rotating with the rotation of the first rotating shaft 12. Two vertically arranged pressure rollers 16 are rotatably disposed inside the mounting bracket 143. The two pressure rollers 16 can be moved closer or further apart to adjust the distance between them. The two pressure rollers 16 are used to press the plastic strip.
[0018] like Figure 3As shown, the mounting bracket 143 consists of two horizontal plates 1431 and two vertical plates 1432. Each of the two vertical plates 1432 has a cavity 1433, and each of the opposite sides of the two vertical plates 1432 has a through groove. The two through grooves communicate with the two cavities 1433 respectively. A vertical second rotating shaft 17 is rotatably connected to one of the cavities 1433. The end of the second rotating shaft 17 is connected to the inner wall of the cavity 1433 via a bearing. The second rotating shaft 17 consists of two rod segments moving in opposite directions. Each of the two rod segments is threaded with a first vertical moving block 18. Both first vertical moving blocks 18 abut against the inner wall of their respective cavities 1433, allowing them to move in opposite directions, moving closer or further apart, thus adjusting the distance between the two first vertical moving blocks 18. The purpose of separation; another cavity 1433 is fixed with a second limiting rod 19 parallel to the second rotating shaft 17. The second limiting rod 19 is a smooth round rod. The outer periphery of the second limiting rod 19 is slidably connected to two second vertical moving blocks 20. The two second vertical moving blocks 20 abut against the inner wall of the corresponding cavity 1433. The two first vertical moving blocks 18 and the second vertical moving blocks 20 correspond one-to-one to form two sets of moving components. The first vertical moving block 18 and the second vertical moving block 20 in each set of moving components are rotatably connected by a rotating shaft 21 through a bearing. The two rotating shafts 21 are both through slots. The two rotating shafts 21 are both parallel to the take-up roller 3. The two pressure rollers 16 are fixed on the outer periphery of the two rotating shafts 21. Therefore, the two pressure rollers 16 can rotate around the corresponding rotating shafts 21, and the rotation directions of the two pressure rollers 16 are opposite.
[0019] like Figure 2 As shown, the top surface of the operating table 1 is provided with a horizontal slide groove 22. The slide groove 22 is located at the end of the drive shaft 2 away from the motor 8. A slider 23 is slidably connected in the slide groove 22. An auxiliary support block 24 is rotatably connected to the top of the slider 23. A deep groove ball bearing 25 is fixed in the auxiliary support block 24 by interference fit. The deep groove ball bearing 25 is used to support the end of the drive shaft 2 away from the motor 8 and realizes the stable rotation of the drive shaft 2 through rotational fit. The structure allows the worker to manually move the auxiliary support block 24 to approach or move away from the end of the drive shaft 2 away from the motor 8, which can not only realize the stable rotation of the drive shaft 2, but also facilitate the removal of the roll material from the end of the drive shaft 2 away from the motor 8.
[0020] Working principle: Before use, move the second baffle 6 to the appropriate position according to the width of the plastic strip and lock it.
[0021] When in use, one end of the plastic strip is installed on the take-up roller 3 through the guide assembly. The specific operation is as follows: place the plastic strip between the two pressure rollers 16, and then rotate the second rotating shaft 17. The second rotating shaft 17 drives the two first vertical moving blocks 18 to move closer to each other to squeeze the plastic strip. Then, the drive assembly is started. The specific operation is as follows: the motor 8 is started, and the output end of the motor 8 drives the transmission shaft 2 to rotate. The rotation of the transmission shaft 2 drives the take-up roller 3 to rotate. The rotation of the transmission shaft 2 also drives the gear 10 connected to the transmission shaft 2 to rotate. The rotation of the gear 10 drives the rack 13 to move. The movement of the rack 13 drives another gear 10 to rotate. The rotation of the other gear 10 drives the first rotating shaft 12 connected to it to rotate. The rotation of the first rotating shaft 12 drives the first horizontal moving block 141 to move back and forth, thereby driving the plastic strip to move back and forth, so that the plastic strip is evenly distributed on the take-up roller 3. After a batch of plastic strips is wound up, the plastic restraint strips are passed sequentially through the groove 7 of the second baffle 6, the operating groove 4 of the winding roller 3, and the groove 7 of the first baffle 5 to wrap and restrain the roll material.
[0022] Finally, move the auxiliary support block 24 away from the drive shaft 2, remove the packaged roll from the winding roller 3, and begin the next batch of winding.
[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
