Description

Technical Field

[0001] This utility model relates to the field of winding tooling technology, and more specifically, to an anti-deviation positioning tooling for winding polyester fabric. Background Technology

[0002] In the production and processing of polyester fabric, the winding process is a crucial step to ensure the quality of subsequent storage, transportation, and processing. Winding fixtures are used to neatly wind the continuously produced fabric onto the winding rollers. Currently, most commonly used polyester fabric winding fixtures in the industry only have basic winding functions, consisting of a base, support plate, winding rollers, and a drive unit. The drive unit rotates the winding rollers to achieve fabric winding.

[0003] Existing winding devices typically use clamps to fix both ends of the roll, and these clamps are set relatively short to facilitate disassembly of the roll. By driving one of the clamps to rotate, the roll rotates and the fabric is wound up. However, in use, because the clamps extend only a short distance into the roll, the contact area between them and the inner wall of the roll is small, and the radial constraint range is limited. This makes it difficult to effectively limit the positional deviation of the roll during rotation, which easily leads to radial offset and axial movement, ultimately causing the wound fabric roll to have a taper and interlayer misalignment. Utility Model Content

[0004] Based on the aforementioned technical problems of traditional winding devices, such as short insertion length of the locking block into the drum, small contact area, and limited radial constraint range, which lead to easy radial offset and axial movement when the drum rotates, ultimately resulting in tapering and interlayer misalignment of the fabric roll, this utility model proposes an anti-offset positioning tool for polyester fabric winding.

[0005] This utility model proposes an anti-deviation positioning fixture for winding polyester fabric, comprising a base, with two support plates fixedly connected to the top of the base. One support plate has a winding roller rotatably connected to it and a driving component installed thereon. Multiple snap-fit ​​components are installed on the outer wall of the winding roller. The other support plate has an mounting sleeve fixedly connected to it and a driving component installed thereon. A support rod is slidably connected to the inner wall of the mounting sleeve, and a locking rod is rotatably connected to the end of the support rod. The driving component is used to drive the winding roller to rotate, and the driving component is used to drive the support rod to slide along the inside of the mounting sleeve.

[0006] Preferably, the driving component is a first stepper motor, the base of which is fixedly mounted on the top of the support plate, and the output end of which is fixedly connected to the take-up roller.

[0007] Preferably, the snap-fit ​​assembly includes multiple brackets, a slide rod is slidably connected to the inner wall of the bracket, a snap block is fixedly connected to the end of the slide rod, the end of the snap block extends into the take-up roller and is slidably connected thereto, a spring is sleeved on the outer wall of the slide rod, and multiple snap slots are opened on the outer wall of the snap rod, with the snap block engaging with the snap slots.

[0008] Preferably, one end of the spring is fixedly connected to the bracket, and the other end of the spring is fixedly connected to the slide rod.

[0009] Preferably, the drive assembly includes a second stepper motor, the output end of which is fixedly connected to a gear, and the output end of which is rotatably connected to a support block, the bottom of which is fixedly connected to the top of the support plate.

[0010] Preferably, the drive assembly further includes a toothed plate, the outer wall of the support rod is provided with a groove, the toothed plate is fixedly connected to the inner wall of the groove, and the gear meshes with the toothed plate.

[0011] Preferably, a limiting plate is fixedly connected to the inner wall of the mounting sleeve, and the limiting plate is slidably connected to the inner wall of the groove.

[0012] Preferably, a fixing block is fixedly connected to the outer wall of the mounting sleeve, and the bottom of the fixing block is fixedly connected to the support plate.

[0013] Preferably, a limiting plate is fixedly connected to the end of the mounting sleeve, a limiting moving plate is sleeved on the outer wall of the take-up roller, a cylinder is fixedly connected to the outer wall of the support plate, and the output end of the cylinder passes through the support plate and is fixedly connected to the limiting moving plate.

[0014] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0015] 1. By setting up snap-fit ​​components, support rods, and snap-fit ​​rods, radial constraints can be provided. The snap-fit ​​blocks of the snap-fit ​​components are driven by springs to embed into the slots of the snap-fit ​​rods, forming multi-point, large-area radial contact constraints, replacing the traditional single set of short snap-fit ​​blocks, expanding the radial constraint range, effectively limiting radial offset during roll rotation, and avoiding misalignment between fabric roll layers due to radial displacement. The snap-fit ​​rods dock with the snap-fit ​​components to avoid snap-fit ​​misalignment. The direct connection between the mounting sleeve and the support plate, and between the take-up roller and the drive component, ensures structural stability throughout the entire take-up process, without additional shaking, and reduces the risk of roll offset.

[0016] 2. After the card block is embedded in the slot of the card rod, it forms multi-point radial support, increases the contact constraint range with the inner wall of the drum, and solves the defects of small contact area and insufficient constraint of traditional short card blocks.

[0023] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model. In this utility model, unless otherwise expressly specified and limited, the term "fixed connection" should be interpreted broadly. For example, "fixed connection" can mean fixed installation, detachable connection, or integral; it can mean mechanical connection or electrical connection; it can mean direct connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figures 1-5 As shown, a polyester fabric winding anti-deviation positioning fixture includes a base 1. Two support plates 2 are fixedly connected to the top of the base 1. A winding roller 4 and a driving component are rotatably connected inside one of the support plates 2. Multiple snap-fit ​​components are installed on the outer wall of the winding roller 4. An mounting sleeve 15 and a driving component are fixedly connected inside the other support plate 2. A support rod 16 is slidably connected to the inner wall of the mounting sleeve 15. A locking rod 20 is rotatably connected to the end of the support rod 16. The driving component is used to drive the winding roller 4 to rotate, and the driving component is used to drive the support rod 16 to slide along the inside of the mounting sleeve 15.

[0025] By replacing the traditional single short locking block 10 with the locking assembly, support rod 16, and locking rod 20, the radial constraint contact area and range of the drum can be increased, solving the problem of drum offset caused by insufficient radial constraint in traditional devices. The insertion of the locking rod 20, together with the drive component of the take-up roller 4, forms an integrated structure for fixed drive and take-up, providing a basis for anti-offset take-up. At the same time, the sliding fit between the mounting sleeve 15 and the support rod 16 ensures stable locking action and avoids locking misalignment.

[0026] like Figure 1 As shown, the driving component is the first stepper motor 3. The base of the first stepper motor 3 is fixedly installed on the top of the support plate 2, and the output end of the first stepper motor 3 is fixedly connected to the take-up roller 4.

[0027] like Figure 1 and Figure 2 As shown, the snap-fit ​​assembly includes multiple brackets 7, with a slide rod 8 slidably connected to the inner wall of the bracket 7. A snap block 10 is fixedly connected to the end of the slide rod 8. The end of the snap block 10 extends into the take-up roller 4 and is slidably connected thereto. A spring 9 is sleeved on the outer wall of the slide rod 8. Multiple snap slots 21 are opened on the outer wall of the snap rod 20. The snap block 10 is snapped into the snap slot 21. One end of the spring 9 is fixedly connected to the bracket 7, and the other end of the spring 9 is fixedly connected to the slide rod 8.

[0028] After the card block 10 is embedded in the slot 21 of the card rod 20, it forms a multi-point radial support, increases the contact constraint range with the inner wall of the drum, and solves the defects of small contact area and insufficient constraint of traditional short card blocks.

[0029] like Figure 3 As shown, the drive assembly includes a second stepper motor 11, with a gear 13 fixedly connected to the output end of the second stepper motor 11, and a support block 12 rotatably connected to the output end of the second stepper motor 11. The bottom of the support block 12 is fixedly connected to the top of the support plate 2. The drive assembly also includes a toothed plate 19, with a groove 17 formed on the outer wall of the support rod 16. The toothed plate 19 is fixedly connected to the inner wall of the groove 17, and the gear 13 meshes with the toothed plate 19. A limiting plate 18 is fixedly connected to the inner wall of the mounting sleeve 15, and the limiting plate 18 is slidably connected to the inner wall of the groove 17. A fixing block 14 is fixedly connected to the outer wall of the mounting sleeve 15, and the bottom of the fixing block 14 is fixedly connected to the support plate 2.

[0030] The meshing transmission efficiency of gear 13 and toothed plate 19 is high and there is no risk of slippage, ensuring that the sliding speed of support rod 16 is uniform and avoiding jamming when the locking rod 20 is inserted.

[0031] The groove 17 provides installation space for the toothed plate 19 and cooperates with the limiting plate 18 to ensure the accurate sliding trajectory of the support rod 16.

[0032] like Figure 1 and Figure 2As shown, the end of the mounting sleeve 15 is fixedly connected to the limiting plate 22, the outer wall of the winding roller 4 is fitted with the limiting moving plate 6, and the outer wall of the support plate 2 is fixedly connected to the cylinder 5. The output end of the cylinder 5 passes through the support plate 2 and is fixedly connected to the limiting moving plate 6.

[0033] Working principle: The roll to be wound is placed on the outer wall of the take-up roller 4. The take-up roller 4 can extend to the middle of the inner wall of the roll. The roll is fixed by installing a positioning pin for filling the gap between the take-up roller 4 and the roll. The cylinder 5 is started to push the limiting moving plate 6 to slide along the take-up roller 4. In conjunction with the limiting fixed plate 22 at the end of the mounting sleeve 15, the roll is axially limited from both ends to restrict the axial movement of the roll.

[0034] The second stepper motor 11 of the drive assembly is started, and its output end drives the gear 13 to rotate. The gear 13 meshes with the toothed plate 19 in the slide groove 17 of the support rod 16, driving the support rod 16 to slide along the inner wall of the mounting sleeve 15, so that the locking rod 20 at the end of the support rod 16 is inserted into the take-up roller 4.

[0035] The first step motor 3 of the start-up drive unit drives the take-up roller 4 to rotate. The take-up roller 4 drives the drum to rotate synchronously through multiple sets of snap-fit ​​components to wind up the polyester fabric. During the process, the slot 21 on its outer wall aligns with the snap-fit ​​block 10 on the snap-fit ​​component of the take-up roller 4. The spring 9 pushes the slide rod 8 to slide along the bracket 7, so that the snap-fit ​​block 10 is embedded in the slot 21, forming multiple sets of radial snap-fit ​​structures, increasing the contact constraint range with the inner wall of the drum and limiting the radial displacement of the drum.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
