Description

Technical Field

[0001] This utility model belongs to the field of fabric brushing technology, specifically a brushing device for suede fabric. Background Technology

[0002] In the textile industry, suede fabric is widely used in clothing, bags, and home décor due to its soft touch, delicate nap, and unique appearance. The napping process is a key technique that gives suede its special texture; through the mechanical friction of napping equipment, a uniform and dense nap layer is formed on the fabric surface.

[0003] Currently, traditional suede fabric brushing equipment suffers from low maintenance efficiency. As a consumable part, the brushing roller needs to be replaced frequently after long-term use. However, the existing equipment's brushing rollers are mostly installed and disassembled independently, which is a cumbersome operation process. Only one brushing roller can be disassembled at a time, resulting in long downtime and seriously affecting production efficiency. To address this, we propose a suede fabric brushing treatment device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4A suede fabric brushing device includes a first brushing roller 16 and a second brushing roller 161. A set of limiting shafts 162 are mounted on both the left and right sides of the first and second brushing rollers 16 and 161. A set of square holes is opened on both the left and right sides of the first and second brushing rollers 16 and 161. A block 163 is fixedly installed on the outer side of the limiting shaft 162 and inserted into the square hole. A sliding plate 17 is mounted on the outer side of the limiting shaft 162 on the left side of the first and second brushing rollers 16 and 161, and a synchronous pulley 19 is connected to the left side. A synchronous belt 2 meshes with the outer sides of the two sets of synchronous pulleys 19. A hydraulic rod 15 is connected to the outer side of the sliding plate 17. Two sets of first mounting holes are evenly opened on the left side of the sliding plate 17. The limiting shaft 162 on the left side of the first grinding roller 161 is rotatably mounted in the first mounting opening. The synchronous wheel 19 is located on the left side of the sliding plate 17. When the first grinding roller 16 rotates, it drives the block 163 in the square hole on its left side to rotate. This block 163 drives the limiting shaft 162 supported by the first grinding roller 16 to rotate. This limiting shaft 162 drives a set of synchronous wheels 19 to rotate. The synchronous wheels 19 drive another set of synchronous wheels 19 to rotate via the synchronous belt 2. This causes the limiting shaft 162 outside the other set of synchronous wheels 19 to rotate, which in turn drives the block 163 on the limiting shaft 162 to rotate, which in turn drives the second grinding roller 161. This achieves synchronous rotation of the first grinding roller 16 and the second grinding roller 161. The sliding plate 17... A top plate 12 is mounted on top, and a T-shaped groove is formed at the bottom of the top plate 12. A T-shaped guide block 21 is fixedly installed on the top of the sliding plate 17. The T-shaped guide block 21 is slidably disposed in the T-shaped groove, which has a through hole. A threaded hole is formed on the top of the T-shaped guide block 21, and an anti-loosening bolt 14 is fixedly installed in the through hole. The anti-loosening bolt 14 is screwed through the through hole of the top plate 12 and into the threaded hole of the T-shaped guide block 21 to fix the position of the T-shaped guide block 21, thereby fixing the position of the sliding plate 17 at the bottom of the T-shaped guide block 21. This prevents the sliding plate 17 from moving due to the failure of the hydraulic rod 15, thus improving the reliability of the device. The anti-loosening bolt 14 is screwed into the threaded hole, and a groove is formed on the top of the top plate 12. A hydraulic rod 15 is fixedly installed in the groove. The telescopic end of the hydraulic rod 15 passes through the groove and the T-shaped slide and is connected to the T-shaped guide block 21. The hydraulic rod 15 drives the T-shaped guide block 21 to move to the left, thereby driving the sliding plate 17 to move to the left with the assistance of the guide wheel 18. This, in turn, drives the limiting shaft 162 and the block 163 on the outside of the sliding plate 17 to move to the left and separate from the first grinding roller 16 and the second grinding roller 161. In this way, the first grinding roller 16 and the second grinding roller 161 can be unlocked at the same time. A support plate 11 is fixedly installed on the bottom right side of the top plate 12. Two sets of second mounting ports are evenly opened on the right side of the support plate 11. The limiting shaft 162 located on the left side of the first grinding roller 16 and the second grinding roller 161 is rotatably installed in the second mounting port.A servo motor 13 is fixedly installed on the right side of the support plate 11. It is located on the right side of the right limit shaft 162 of the first grinding roller 16 and connected to the output end of the servo motor 13. The servo motor 13 drives the right limit shaft 162 of the first grinding roller 16 to rotate, thereby causing the block 163 on the limit shaft 162 to drive the first grinding roller 16 to rotate. A base 1 is fixedly installed at the bottom of the support plate 11. Two sets of support sleeves 23 are evenly fixedly installed on the top of the base 1. Two sets of guide rollers 24 are evenly rotatably installed between the two sets of support sleeves 23. The two sets of guide rollers 24 are respectively located on the first grinding roller 16. At the bottom of the second abrasive roller 161, the suede fabric is guided into the rewinding machine via an unwinding machine with a tensioning function. During this process, the suede fabric is placed on two sets of guide rollers 24 and comes into contact with the first abrasive roller 16 and the second abrasive roller 161. When the suede fabric is rewinding, it slides on the guide rollers 24. At this time, the rapidly rotating first abrasive roller 16 and the second abrasive roller 161 abrade the suede fabric. Two sets of guide grooves are evenly distributed on the top left side of the base 1, and two sets of guide wheels 18 are evenly fixed at the bottom of the sliding plate 17. The guide wheels 18 are rolled within the guide grooves.

[0018] Working principle: Anti-loosening bolts 14 are used to thread through the through hole of the top plate 12 and connect to the threaded hole of the T-shaped guide block 21, thereby fixing the position of the T-shaped guide block 21 and the sliding plate 17 at the bottom of the T-shaped guide block 21. This prevents the sliding plate 17 from moving due to the failure of the hydraulic rod 15, thus improving the reliability of the device. The servo motor 13 drives the limit shaft 162 on the right side of the first grinding roller 16 to rotate, which in turn causes the block 163 on the limit shaft 162 to drive the first grinding roller 16 to rotate. When the first grinding roller 16 rotates, it drives the block 163 located in the square hole on its left side to rotate, thereby driving the limit shaft 162 supported by the first grinding roller 16 to rotate. Shaft 162 drives a set of synchronous pulleys 19 to rotate. The synchronous pulleys 19 drive another set of synchronous pulleys 19 to rotate via synchronous belt 2. This causes the limiting shaft 162 on the outer side of the other set of synchronous pulleys 19 to rotate, which in turn drives the block 163 on the limiting shaft 162 to rotate, which in turn drives the second abrasive roller 161. This achieves synchronous rotation of the first abrasive roller 16 and the second abrasive roller 161, guiding the suede fabric through the unwinding machine with tensioning function into the winding machine. During this process, the suede fabric is placed on two sets of guide rollers 24 and comes into contact with the first abrasive roller 16 and the second abrasive roller 161. When the suede fabric is wound up, it slides on the guide rollers 24. At this time, the rapidly rotating first abrasive roller 16 and the second abrasive roller 161 abrade the suede fabric.

[0019] When it is necessary to disassemble the first grinding roller 16 and the second grinding roller 161, simply rotate the anti-loosening bolt 14 to separate it from the T-shaped guide block 21. Then, the hydraulic rod 15 drives the T-shaped guide block 21 to move to the left, thereby driving the sliding plate 17 to move to the left with the assistance of the guide wheel 18. This, in turn, drives the limiting shaft 162 and the block 163 on the outer side of the sliding plate 17 to move to the left and separate them from the first grinding roller 16 and the second grinding roller 161. In this way, the first grinding roller 16 and the second grinding roller 161 can be unlocked at the same time. At this time, the first grinding roller 16 and the second grinding roller 161 can be moved to the left and separated from the limiting shaft 162 and the block 163 on the outer side of the support plate 11, thus completing the disassembly. When the sliding plate 17 moves to the left, the worker can manually hold the first grinding roller 16 and the second grinding roller 161 to prevent the first grinding roller 16 and the second grinding roller 161 from shifting when the sliding plate 17 moves to the left.
