[0002] Woven bags are a type of plastic bag, mainly used for packaging other objects in daily life. They are made of chemical plastic raw materials such as polyethylene and polypropylene. In the production process of woven bags, it is necessary to collect and store the tubular fabric from the woven tapes. In the existing technology, a motor is often used to drive the winding roller to rotate and collect the tubular fabric.

[0003] Current winding devices have poor compatibility with woven bag tubular fabrics of different widths when winding tubular fabrics, and the tightness of the winding is not easy to control, resulting in generally poor winding quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as poor compatibility with woven bag tubular fabrics of different widths, difficulty in controlling the tightness of the tubular fabric winding, and generally poor winding quality. Therefore, this invention proposes a tubular fabric winding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-7 A tubular fabric winding device includes a symmetrically arranged frame 1 and a vertically arranged column slide 2 on the frame 1. Each column slide 2 is provided with a roll mounting mechanism 4 for mounting a roll 3. The roll 3 is fixed by the roll mounting mechanism 4, and the column slide 2 facilitates the lifting and lowering of the roll 3 during winding.

[0028] The roll mounting mechanism 4 includes an insertion pin 41 corresponding to the roll 3, a connecting sleeve 42 for fixing the insertion pin 41, a sliding sleeve 43 slidably fitted on the outside of the connecting sleeve 42, and a slider 45 fixedly installed in the sliding mounting column groove 2 on the outside of the sliding sleeve 43. The side of the connecting sleeve 42 furthest from the connecting sleeve 42 extends into the sliding sleeve 43 and is integrally formed with a stabilizing ring 422. The stabilizing ring 422 is slidably installed in the sliding sleeve 43, and a compression spring 44 is provided between the side of the stabilizing ring 422 furthest from the connecting sleeve 42 and the inner wall of the connecting sleeve 42. The isomorphic stabilizing ring 422 design ensures a stable sliding connection between the connecting sleeve 42 and the sliding sleeve 43. Combined with the elastic force of the compression spring 44, it provides inward elastic force to the connecting sleeves 42 and the insertion pin 41 on both sides, ensuring a stable fixing effect on the roll 3. To ensure the winding effect of the fabric, a motor or other driving device can be connected to the connecting sleeve 42 via a pulley or other transmission device to drive the roll 3 to rotate. The spring force of the compression spring 44 ensures the clamping and fixing effect on the roll 3. At the same time, when the roll needs to be removed, the sliding sleeve 43 can be slid to remove the roll of tubular cloth.

[0029] Multiple sliding rods 451 can be vertically arranged in the column slide groove 2, and the sliding rods 451 pass through the slider 45 and are slidably connected to it to ensure the stable sliding of the slider 45.

[0030] The frame 1 has a tension roller 5 on its inner side and a corresponding drive assembly. The slider 45 has blocking blocks 46 on both sides. The blocking blocks 46 extend from the side wall of the column slide groove 2 and are slidably connected to multiple elastic limiting components 47 for restricting the upward movement of the blocking blocks 46. The drive assembly drives the tension roller 5 to rotate, facilitating the smooth winding of the tubular fabric onto the roll 3. The design of the elastic limiting components 47 and the blocking blocks 46 prevents the slider 45 from rising during winding, ensuring the tension of the roll 3 on the tubular fabric, guaranteeing the tightness of the winding, and ensuring the winding quality of the tubular fabric roll.

[0031] Based on the above technical solution, when winding the woven bag tubular fabric, the tubular fabric is fed into the winding shaft 3 through the tension roller 5, and the end of the tubular fabric is fixed. The tension roller 5 is driven to rotate in conjunction with the drive assembly to feed the tubular fabric. The winding shaft 3 is driven to rotate in conjunction with the drive equipment to wind the tubular fabric. As the diameter of the tubular fabric roll increases during winding, the winding shaft 3 gradually rises in conjunction with the vertical sliding of the slider 45. When the slider 45 rises, the elastic limiting component 47 and the blocking block 46 provide a certain blocking force to the rise of the slider 45, so that the tubular fabric roll can adhere to the tension roller 5, ensuring the tension force during the winding of the tubular fabric, ensuring the tightness of the winding of the tubular fabric, and ensuring the winding quality of the tubular fabric.

[0032] In this technical solution, such as Figure 1-6 As shown, a connecting shaft 411 is integrally formed on the side of the insertion pin 41 that is away from it. The connecting shaft 411 is rotatably installed in the connecting sleeve 42. The design of the connecting shaft 411 facilitates the installation of the insertion pin 41 and the connecting sleeve 42. When winding different sizes of tubular fabric, an insertion pin 41 with a suitable length of connecting shaft 411 can be selected according to the corresponding width of the roll 3, providing good compatibility and adaptability for tubular fabrics of different widths. Simultaneously, a bearing bush can be embedded in the inner wall of the connecting sleeve 42 to ensure that the connecting shaft 411 can rotate stably within the connecting sleeve 42, ensuring stable winding of the tubular fabric.

[0033] In this technical solution, such as Figure 1-6 As shown, a prism-shaped limiting post 421 is provided on the side of the stabilizing ring 422 that is away from it. A limiting end cap 431 is slidably installed on the outside of the limiting post 421, and the limiting end cap 431 is fixedly installed on the outside of the sliding sleeve 43. The cooperation between the prism-shaped limiting post 421 and the limiting end cap 431 prevents the connecting sleeve 42 from rotating and ensures the stable rotation of the connecting shaft 411.

[0034] In this technical solution, such as Figure 1-7As shown, the elastic limiting component 47 includes elastic locking tongues 471 disposed on both sides of the blocking block 46, a mounting sleeve 472 slidably disposed on the outer side of the elastic locking tongues 471, and a compression spring 473 disposed in the mounting sleeve 472 corresponding to the elastic locking tongues 471. The mounting sleeve 472 is fixedly installed on the side wall of the column slide groove 2. The upper part of the side walls of the blocking block 46 is provided with a guide bevel 461 corresponding to the elastic locking tongues 471, and the lower part of the side walls of the blocking block 46 is provided with a reset bevel 462 to facilitate the downward movement of the blocking block 46. The elastic locking tongues 471, in conjunction with the elastic force of the compression springs 473, block the upward movement of the blocking block 46, providing a certain restriction on the upward movement of the roll 3, ensuring the stable winding of the roll 3 onto the bobbin, and ensuring the tightness of the winding. The design of the guide bevel 461 ensures a stable sliding connection between the elastic locking tongues 471 and the blocking block 46. After winding is completed, the design of the reset bevel 462 avoids the blocking block 46, ensuring the smooth reset of the slider 45. By using multiple elastic limiting components 47 arranged as needed, the uniformity of the pressure applied to the slider 45 can be ensured as much as possible, thus ensuring uniform winding of the fabric.

[0035] In this technical solution, such as Figure 1 and 2 As shown, the drive assembly includes a synchronous pulley 51 disposed on one side of the two tension rollers 5, a synchronous belt 52 fitted on the outer side of the two synchronous pulleys 51, and a drive motor 53 connected to the outer side of one of the tension rollers 5 via a transmission belt.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
