Description

Technical Field

[0001] This utility model relates to the field of shoe fabric unwinding technology, and in particular to a shoe fabric unwinding device. Background Technology

[0002] In the footwear manufacturing process, the unwinding of the fabric is a crucial preliminary step. Its stability and efficiency directly affect the quality and speed of subsequent sewing, bonding, and other processes. Traditional fabric unwinding devices, which are widely used in the industry, have revealed many shortcomings that urgently need to be addressed in actual operation.

[0003] First, the roll changing operation is cumbersome and inefficient. When a roll of fabric is used up or needs to be replaced with a different specification of material, operators usually need to use tools or work in groups, which is not only time-consuming and labor-intensive, reducing overall production efficiency, but also particularly prominent when changing frequently. Second, the fabric is prone to loosening and shifting during use. Existing devices often lack effective roll limiting or material restraint mechanisms. During equipment start-up, shutdown, or high-speed operation, the fabric layer on the roll is very prone to loosening, shifting, or even falling off due to inertia or vibration. This not only wastes materials but also forces operators to frequently stop the machine for manual sorting and resetting, significantly increasing labor intensity and becoming a bottleneck for the smooth operation of the production line. Third, tension control is unstable and inconvenient to adjust. Maintaining constant and appropriate tension during fabric unwinding is crucial to ensuring the quality of subsequent processing. However, traditional devices rely heavily on manual mechanical structures for tension adjustment, which is not convenient enough and makes it difficult to achieve real-time, dynamic, and stable tension control. Excessive tension fluctuations can easily lead to fabric stretching, deformation, wrinkling, or even breakage, seriously affecting product quality and increasing defect rates and rework costs. Utility Model Content

[0004] To overcome the technical defects of the existing technology, this utility model provides a shoe fabric unwinding device, which has the advantages of simple structure, convenient operation and adjustable tension.

[0005] The technical solution adopted by this utility model is as follows: it includes a bracket and a fiberboard installed on the rear side of the equipment. There are two fiberboards, which are fixedly installed at both ends of the bracket. Each of the two fiberboards has a slot on its other side. A placement component for placing the hook tape material is inserted between the two slots. A fixing frame is fixed on one side of one of the fiberboards. A tension adjustment component is fixedly installed inside the fixing frame and is fixedly installed on the outside of the fiberboard.

[0006] Preferably, in order to quickly replace the material of the hook strap on the outside of the mounting shaft, the placement assembly includes a mounting shaft, both ends of which are provided with storage slots. A first spring is fixedly installed inside each storage slot, and a plug is fixed to the other end of the first spring. The plug is inserted into the slot.

[0007] Preferably, in order to facilitate the worker to pull the plug and detach it from the slot, a square opening is provided on the outside of the mounting shaft, the square opening is connected to the storage groove, and a lever is fixed at the bottom of the plug and the lever is located inside the square opening.

[0008] Preferably, in order to limit the material roll of the hook and prevent it from falling off the mounting shaft, a mounting groove is provided on the outside of the mounting shaft, and a baffle is hinged inside the mounting groove.

[0009] Preferably, a second spring is fixedly installed between one side of the baffle and the bottom of the mounting groove for supporting the baffle.

[0010] Preferably, in order to flexibly adjust the position of the adjusting rod, the tension adjusting assembly includes a motor for driving and a connecting rod. The motor is fixedly installed inside the fixing frame, one end of the connecting rod is fixed to the output shaft of the motor, and the other end of the connecting rod is fixed to an adjusting rod.

[0011] Preferably, in order to limit the adjustment rod and improve its stability, a first arc-shaped frame and a second arc-shaped frame are fixedly installed on the outer sides of the two fiberboards respectively. The first arc-shaped frame has an arc-shaped opening, and the second arc-shaped frame has an arc-shaped groove.

[0012] Preferably, in order to further improve the sliding stability of the adjusting rod, the other end of the adjusting rod is slidably installed inside the arc-shaped groove through the arc-shaped opening.

[0013] The beneficial effects of this utility model are as follows: through the insertion of the slots on the two fiberboards into the placement component, and with the elastic reset action of the first spring, the entire placement component, along with the hooked material roll on it, can be easily installed or removed from the bracket. Furthermore, the mounting groove on the outside of the mounting shaft and the hinged baffle with the second spring form a protective structure, creating a physical constraint on the hooked material roll. This eliminates the need for workers to repeatedly pull and arrange the hooked material, reducing the labor intensity of the workers. At the same time, by utilizing the tension adjustment component, appropriate tension can be continuously and stably applied to the hooked material, significantly reducing tension fluctuations and improving the unwinding quality and the stability of subsequent processing.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-5 As shown, this embodiment provides a shoe fabric unwinding device, including a bracket 1 and a fiberboard 2 installed on the rear side of the device. There are two fiberboards 2, which are respectively fixedly installed at both ends of the bracket 1. Each of the two fiberboards 2 has a slot 6 on its other side. A placement component 3 for placing hook tape material is inserted between the two slots 6. The placement component 3 can be quickly disassembled and assembled, which facilitates the replacement of the hook tape material roll. A fixing frame 4 is fixed on one side of one of the fiberboards 2. A tension adjustment component 5 is fixedly installed inside the fixing frame 4 and is fixedly installed on the outside of the fiberboard 2.

[0022] In actual use, the operator first places the hooked material roll onto the placement component 3 and then inserts the placement component 3 into the slot 6 on the fiberboard 2. This allows for the quick installation of the placement component 3 and the hooked material roll onto the bracket 1. The entire process is convenient, time-saving, and labor-saving, significantly improving production efficiency. At the same time, the placement component 3 can limit the hooked material roll, preventing it from falling off the mounting shaft 301, further ensuring the stability and reliability of the unwinding device. Moreover, it eliminates the need for workers to repeatedly pull and arrange the hooked material, reducing the labor intensity of the workers. In addition, the tension adjustment component 5 can flexibly adjust the tension of the hooked material, achieving continuous and stable tension application, significantly reducing tension fluctuations, and improving the unwinding quality and the stability of subsequent processing.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the placement component 3 includes a mounting shaft 301. Both ends of the mounting shaft 301 have storage slots 302. A first spring 303 is fixedly installed inside each storage slot 302. The other end of the first spring 303 is fixed with an insert block 304. The insert block 304 is inserted into the slot 6. A square opening 306 is provided on the outside of the mounting shaft 301. The square opening 306 communicates with the storage slot 302. A lever 305 is fixed at the bottom of the insert block 304 and is located inside the square opening 306, which can adjust the position of the insert block 304. A mounting groove 309 is provided on the outside of the mounting shaft 301. A baffle 308 is hinged inside the mounting groove 309. A second spring 307 is fixedly installed between one side of the baffle 308 and the bottom of the mounting groove 309.

[0024] In use, the operator can manually move the lever 305 inside the square opening 306 to move the insert 304 within the receiving slot 302 and compress the first spring 303 until the insert 304 is completely disengaged from the slot 6. At this point, the placement component 3, along with the hook and material roll attached to it, can be removed from between the two fiberboards 2, enabling quick disassembly of the placement component 3 and facilitating the replacement of the hook and material roll. After replacement, the placement component 3 is aligned with the slots 6 on the two fiberboards 2 and inserted until the insert 304 is engaged inside the slot 6 under the elastic reset action of the first spring 303. The reinstallation of component 3 along with the hook and material roll on bracket 1 can be completed in a convenient, time-saving, and labor-saving manner, significantly improving production efficiency. Meanwhile, a baffle 308 is hinged in the mounting groove 309 on the outside of mounting shaft 301, and a second spring 307 is fixedly installed between one side of baffle 308 and the bottom of mounting groove 309. When the hook and material roll is sleeved on mounting shaft 301, the baffle 308 limits the hook and material roll under the elastic force of the second spring 307, preventing it from falling off mounting shaft 301, further ensuring the stability and reliability of the unwinding device.

[0025] As a technical optimization solution of this utility model, specifically as follows: Figure 5 As shown, the tension adjustment assembly 5 includes a motor 501 and a connecting rod 502 for driving. The motor 501 is fixedly installed inside the fixed frame 4. One end of the connecting rod 502 is fixed to the output shaft of the motor 501. The connecting rod 502 can connect the output shaft of the motor 501 and the adjusting rod 503 together. The other end of the connecting rod 502 is fixed with the adjusting rod 503. A first arc frame 504 and a second arc frame 506 are fixedly installed on the outer sides of the two fiberboards 2 respectively. The first arc frame 504 has an arc-shaped through-hole 505, and the second arc frame 506 has an arc-shaped slot 507. The other end of the adjusting rod 503 passes through the arc-shaped through-hole 505 and is slidably installed inside the arc-shaped slot 507.

[0026] In use, the operator can start the motor 501 to drive the connecting rod 502 and the adjusting rod 503 to rotate synchronously. Since the other end of the adjusting rod 503 is slidably installed inside the arc-shaped groove 507, the adjusting rod 503 can slide within the arc-shaped groove 507 while rotating, thereby achieving flexible adjustment of the tension of the hook material to meet different processing requirements, ensuring the unwinding quality and the stability of subsequent processing. In addition, the setting of the first arc-shaped frame 504 and the second arc-shaped frame 506 plays a good limiting role for the adjusting rod 503, improving the stability of the adjusting rod 503 and further ensuring the overall performance of the unwinding device.
