Description

Technical Field

[0001] This utility model relates to the field of abrasive cloth transfer equipment, specifically to an abrasive cloth transfer device. Background Technology

[0002] The production of abrasive belts generally includes four processes: raw fabric treatment, roll manufacturing, post-processing of the rolls, and conversion. These four processes are described below: Raw fabric treatment refers to the substrate used in abrasive belts, which can be cloth, paper, or a composite substrate. Paper, except for waterproof paper, generally does not require treatment. The composite substrate is a combination of paper and cloth, sometimes purchased directly from a supplier, or completed on the raw fabric treatment line or roll manufacturing line at the abrasive belt manufacturer. This section mainly describes the main processes of fabric substrate treatment, including scraping, singeing, dewaxing, dyeing, impregnation and sizing, stretching, and calendering. Different processes are selected depending on the specific requirements. Roll manufacturing includes the main processes of label printing, adhesive coating, sanding, re-adhesion, and drying. These processes are all completed on a single production line, forming a coordinated operation. Post-processing of the rolls refers to the series of treatments the abrasive cloth undergoes after it leaves the drying chamber before entering the conversion process. Post-processing of the rolls includes post-curing, storage, humidification, and flexing. Only after these treatment processes can the performance and quality of the abrasive cloth reach the predetermined goals. Conversion refers to the process of converting a large roll of abrasive cloth into abrasive belts or products in disc, sheet, or other shapes.

[0003] After the raw abrasive cloth is processed, especially in the stretching and calendering stages, stretching is achieved by using rollers of different speeds to guide and convey the raw abrasive cloth material. The varying friction between the rollers and the material during transport stretches the raw abrasive cloth. It is then sent to a heat treatment unit for shaping, followed by calendering, which completes the raw cloth processing. Finally, it is wound up for subsequent processing, primarily large-roll manufacturing, including label printing, gluing, sanding, re-gluing, and drying. During the winding stage after raw cloth processing, although the above operations are completed, the raw abrasive cloth material, having undergone heat treatment and not yet cooled to the preset temperature, must still be kept under tension during winding. While existing winding rollers on the market are capable of winding, the cylindrical portion of the roller receiving the raw abrasive cloth requires bonding or other methods to free the raw abrasive cloth material after processing. In practice, it is easy for the free end of the abrasive cloth material to detach from the take-up roller, which leads to abnormalities in the take-up process. Therefore, there is room for improvement in the existing technology, which aims to effectively clamp the free end of the abrasive cloth material after the original cloth processing stage, so that the abrasive cloth material after the original cloth processing stage can be smoothly completed in the take-up process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides an abrasive cloth transfer device that can conveniently clamp the free end of the abrasive cloth material, thereby overcoming the deficiencies in existing technologies.

[0005] The technical solution adopted by this utility model is as follows: an abrasive cloth transfer device, including a vehicle body, on which two parallel roller mounting frames are provided. Rollers are provided on the two roller mounting frames. Each roller includes a roller body and connecting shafts symmetrically arranged at both ends of the roller body. A clamping groove is formed on the roller body along the side of the roller body towards the central axis of the roller body. A plurality of clamping blocks are arranged at intervals along the central axis of the roller body in the clamping groove. The clamping blocks have an arc-shaped block structure. A first limiting groove matching the shape of the clamping block is provided on the outer side of the roller body of each clamping block. The cross-section of the first limiting groove is rectangular. A second limiting groove with an arc shape is provided on the plurality of first limiting grooves. The plurality of first limiting grooves are all connected to the second limiting grooves. A transmission connecting rod is provided on the plurality of clamping blocks and the second limiting grooves. A connecting ring is provided on each connecting shaft. The number of connecting rings is two. Both connecting rings are connected to the transmission connecting rod. A torsion spring is provided on each connecting ring and the adjacent connecting shaft.

[0006] Preferably, each connecting ring is provided with a one-way damping bearing on the side away from the roller body. Each one-way damping bearing is mounted on an adjacent connecting shaft. Each one-way damping bearing includes an outer ring. A first connecting slider is provided on the outer ring of each one-way damping bearing. A transmission sleeve is correspondingly provided on each first connecting slider. The transmission sleeve is movably connected to the outer ring of the adjacent one-way damping bearing and to the first connecting slider. A second connecting slider is provided on one side of each first connecting slider. The second connecting slider is mounted on an adjacent connecting ring. A first limiting groove is provided on the inner wall of each transmission sleeve. The shapes of some of the first connecting sliders and some of the second connecting sliders are matched with the shape of the first limiting groove.

[0007] Preferably, each of the transmission sleeves is provided with a handle on the side away from the roller body, and the handle is mounted on the outer ring of the adjacent one-way damping bearing.

[0008] Preferably, each of the clamping blocks has a crisscrossing groove structure on one end near the clamping groove.

[0009] Preferably, the vehicle body is equipped with a drive motor, the output end of the drive motor is equipped with a first sprocket, each roller mounting frame and the adjacent connecting shaft are respectively equipped with a ball bearing, the connecting shaft above the first sprocket is equipped with a second sprocket, and the first sprocket and the second sprocket are equipped with a transmission chain.

[0010] Preferably, the bottom of the vehicle body is provided with casters and foot supports, and the number of foot supports and casters is several. The several foot supports are symmetrically distributed on both sides of the central axis of the roller body. Each foot support includes a fixed plate provided on the vehicle body, a first top plate provided at the top of the fixed plate on the side away from the vehicle body, a movable plate provided below the first top plate, a second top plate provided at the end of the movable plate near the first top plate, several second limiting grooves opened on the movable plate along the direction from near the first top plate to away from the first top plate, a first bolt provided on each second limiting groove and the fixed plate, and a second bolt provided on the second top plate and the first top plate.

[0011] The beneficial effects of this utility model are as follows: First, this utility model utilizes a rotating connecting ring to drive the transmission connecting rod to rotate, thereby driving several clamping blocks to move and release or clamp the free end of the abrasive cloth material. When it is necessary to clamp the free end of the abrasive cloth material, the transmission sleeve needs to be moved until it is located on the adjacent first and second connecting sliders, so that the resistance provided by the one-way damping bearing can be used to clamp the free end of the abrasive cloth material. When it is necessary to release the clamped free end of the abrasive cloth material, the transmission sleeve needs to be moved again until the transmission sleeve and the second connecting slider are disengaged. At this time, the connecting ring rotates in the opposite direction under the elastic force provided by the adjacent torsion spring, thereby driving the transmission connecting rod and several clamping blocks to rotate in the opposite direction to release the free end of the abrasive cloth material, so that the free end of the abrasive cloth material can be smoothly removed from this product.

[0012] Secondly, each of the clamping blocks in this invention has a crisscrossing groove structure on the end near the clamping groove; this facilitates increasing the roughness of the end of the clamping block near the clamping groove, thereby providing a greater coefficient of friction when the clamping block is used to clamp the free end of the original abrasive cloth material.

[0013] Furthermore, the bottom of the vehicle body described in this utility model is provided with casters and foot supports. The number of casters and foot supports is several. Installing several casters facilitates moving the vehicle body, and installing several foot supports facilitates adjusting the vehicle body to a preset level using several foot supports.

[0014] This utility model has a simple structure, is easy to operate, and has a clever design, which greatly improves work efficiency and has good social and economic benefits. It is a product that is easy to promote and use. Attached Figure Description

[0018] Figure 4 for Figure 1 A magnified view of detail C. Detailed Implementation

[0019] like Figures 1 to 4 As shown, a sandpaper transfer device includes a vehicle body 1. Two parallel roller mounting frames 2 are mounted on the vehicle body 1. Rollers are mounted on the two roller mounting frames 2. Each roller includes a roller body 3 and connecting shafts 4 symmetrically arranged at both ends of the roller body 3. A clamping groove 5 is formed on the roller body 3 along its side towards its central axis. A plurality of clamping blocks 6 are arranged at intervals along the central axis of the roller body 3 in the clamping groove 5. The clamping blocks 6 have an arc-shaped block structure. Each clamping block 6 has a connecting shaft 4 on its outer side. The clamping block 6 is fitted with a first limiting groove 7, which has a rectangular cross-section. Several first limiting grooves 7 are provided with arc-shaped second limiting grooves 8, which are connected to the second limiting grooves 8. Several clamping blocks 6 and second limiting grooves 8 are provided with transmission connecting rods 9. Each connecting shaft 4 is provided with a connecting ring 10, and two connecting rings 10 are used. Both connecting rings 10 are connected to the transmission connecting rods 9. Each connecting ring 10 and the adjacent connecting shaft 4 are provided with torsion springs 11.

[0020] After the raw abrasive cloth material undergoes processing, this product is used to complete the winding process, which requires clamping the free end of the raw abrasive cloth material. After winding, the material is transported to the large roll manufacturing line according to process requirements. This product continuously feeds the raw abrasive cloth material to the large roll manufacturing line. During this continuous feeding, the clamping of the free end needs to be released, allowing the free end to detach smoothly from the roller. Therefore, this product provides a one-way damping bearing 12 on the side of each connecting ring 10 away from the roller 3. Each one-way damping bearing 12 is mounted on an adjacent connecting shaft 4. Each unidirectional damping bearing 12 includes an outer ring. Each outer ring of the unidirectional damping bearing 12 is provided with a first connecting slider 13. Each first connecting slider 13 is provided with a corresponding transmission sleeve 14. The transmission sleeve 14 is movably connected to the outer ring of the adjacent unidirectional damping bearing 12. The transmission sleeve 14 is movably connected to the first connecting slider 13. Each first connecting slider 13 is provided with a second connecting slider 15 on one side. The second connecting slider 15 is installed on the adjacent connecting ring 10. Each transmission sleeve 14 has a first limiting groove 16 on its inner wall. The shape of some of the first connecting sliders 13 and the shape of some of the second connecting sliders 15 are matched with the shape of the first limiting groove 16. By rotating the outer ring of the one-way damping bearing 12 to a preset position, the transmission sleeve 14 is moved. At this time, the transmission sleeve 14 is located on the first connecting slider 13 and the second connecting slider 15. The outer ring of the one-way damping bearing 12 continues to rotate, which drives the connecting ring 10 to rotate, and then drives the transmission connecting rod 9 and several clamping blocks 6 to rotate, thereby achieving the clamping of the free end of the abrasive cloth. At the same time, the resistance provided by the one-way damping bearing 12 itself is used to maintain the clamping of the free end of the abrasive cloth. When it is necessary to release the clamping of the free end of the abrasive cloth, the transmission sleeve 14 needs to be moved again. When the transmission sleeve 14 is fully positioned on the first connecting slider 13, the transmission sleeve 14 and the second connecting slider 15 are disengaged. At this time, the one-way damping bearing 12 no longer provides continuous resistance to the second connecting slider 15 through the transmission sleeve 14, and the connecting ring 10 rotates in the opposite direction under the elastic force provided by the corresponding torsion spring 11. This drives the transmission connecting rod 9 and several clamping blocks 6 to rotate in the opposite direction until the clamping blocks 6 are fully positioned in the corresponding first limiting groove 7, thus releasing the clamping of the free end of the abrasive cloth. Furthermore, each transmission sleeve 14 is provided with a handle 17 on the side away from the roller body 3. There are two handles 17, and each handle 17 is ring-shaped. The handles 17 are installed on the outer ring of the adjacent one-way damping bearing 12. This facilitates the use of the handles 17 to drive the outer ring of the one-way damping bearing 12 to rotate.

[0021] Each clamping block 6 has a crisscrossing groove structure on one end near the clamping groove 5. This increases the roughness of the end of the clamping block 6 near the clamping groove 5, thereby providing a greater coefficient of friction when clamping the free end of the abrasive cloth material using the end of the clamping block 6 near the clamping groove 5.

[0022] The vehicle body 1 is equipped with a drive motor 18, and a first sprocket 19 is provided on the output end of the drive motor 18. Each roller mounting frame 2 and the adjacent connecting shaft 4 are respectively provided with a ball bearing 20. A second sprocket 21 is provided on the connecting shaft 4 above the first sprocket 19, and a transmission chain 22 is provided on the first sprocket 19 and the second sprocket 21. This facilitates the use of the drive motor 18 to transmit power, and then uses the transmission assembly composed of the first sprocket 19, the second sprocket 21, and the transmission chain 22 to drive the rollers to rotate and complete the winding process of the abrasive cloth material.

[0023] The bottom of the vehicle body 1 is equipped with casters 23 and foot supports. Several foot supports and casters 23 are provided, symmetrically distributed on both sides of the central axis of the roller body 3. Each foot support includes a fixed plate 24 on the vehicle body 1, a first top plate 25 at the top of the fixed plate 24 away from the vehicle body 1, a movable plate 26 below the first top plate 25, a second top plate 27 at the end of the movable plate 26 near the first top plate 25, several second limiting grooves 28 formed on the movable plate 26 along the direction from near to away from the first top plate 25, a first bolt 29 on each second limiting groove 28 and the fixed plate 24, and second bolts 30 on the second top plate 27 and the first top plate 25. The second bolts 30 are threadedly connected to the first top plate 25, and the second bolts 30 are movably connected to the second top plate 27. The first bolts 29 are threadedly connected to the fixed plate 24. Installing several casters 23 facilitates the movement of the vehicle body 1, and installing several of the aforementioned foot supports facilitates the adjustment of the vehicle body 1 to a preset level using the aforementioned foot supports.

[0024] The instructions for using this product are as follows: Figures 1 to 4As shown, after the product is transported to the preset position corresponding to the winding end of the production line corresponding to the raw fabric processing stage, firstly, the vehicle body 1 of the product is adjusted to a preset level by adjusting several of the aforementioned foot supports. Then, the free end of the abrasive cloth raw material after the raw fabric processing stage is placed into the clamping groove 5, and at the same time, the transmission sleeves 14 located on both sides of the roller body 3 are selected, so that each transmission sleeve 14 is located on the adjacent first connecting slider 13 and the adjacent second connecting slider 15. Then, the two handles 17 are rotated to the preset position. At this time, each handle 17 drives the outer ring of the adjacent one-way damping bearing 12 to rotate, and through the adjacent first connecting slider 13, the adjacent transmission sleeve 14 and the adjacent second connecting slider 15, it drives the transmission connecting rod 9 and several clamping blocks 6 to rotate, thereby clamping the free end of the abrasive cloth raw material. Finally, the drive motor 18 is turned on to complete the winding of the abrasive cloth raw material after the raw fabric processing stage.

[0025] During the large roll manufacturing process, the product containing the raw abrasive cloth material after the initial fabric treatment is moved to a preset position, and the vehicle body 1 is adjusted to a preset level using several of the aforementioned foot supports. Then, the transmission sleeves 14 on both sides of the moving roller 3 disengage from the adjacent second connecting slider 15. At this time, the adjacent connecting ring 10, under the elastic force provided by the corresponding torsion spring 11, rotates in the opposite direction, thereby causing the drive transmission connecting rod 9 and several clamping blocks 6 to rotate in the opposite direction until all clamping blocks 6 are located within the corresponding first limiting groove 7. Meanwhile, the raw abrasive cloth material after the initial fabric treatment is continuously supplied to the large roll manufacturing line under the power provided by the production line. After the raw abrasive cloth material carried by this product has been transported, the aforementioned foot supports should be reset, and the operator can then push the vehicle body 1 and move the product using the universal wheels 23.

[0026] In this embodiment, the rotating connecting ring 10 drives the transmission connecting rod 9 to rotate, thereby driving several clamping blocks 6 to move and release or clamp the free end of the abrasive cloth material. When it is necessary to clamp the free end of the abrasive cloth material, the transmission sleeve 14 needs to be moved until the transmission sleeve 14 is located on the adjacent first connecting slider 13 and second connecting slider 15, so that the resistance provided by the one-way damping bearing 12 can be used to clamp the free end of the abrasive cloth material. When it is necessary to release the clamped free end of the abrasive cloth material, the transmission sleeve 14 needs to be moved again until the transmission sleeve 14 and the second connecting slider 15 are disconnected. At this time, the connecting ring 10 rotates in the opposite direction under the action of the elastic force provided by the adjacent torsion spring 11, thereby driving the transmission connecting rod 9 and several clamping blocks 6 to rotate in the opposite direction to release the free end of the abrasive cloth material, so that the free end of the abrasive cloth material can be smoothly removed from this product.

[0027] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
