Description
Technical Field
[0001] This utility model belongs to the field of brush drums for ceramic fiber polishing machines, and specifically relates to a brush drum for ceramic fiber polishing machines. Background Technology
[0002] Ceramic fibers, with their high strength, high temperature resistance, and corrosion resistance, are widely used in aerospace, automotive manufacturing, electronic equipment, and many other fields. Processing ceramic fibers often requires a roughening process to meet specific requirements. The roughening machine, as a key piece of equipment, relies heavily on its core component, the brush drum, which plays a decisive role in the roughening effect. With industry development, the requirements for the quality, efficiency, and equipment stability of ceramic fiber roughening are constantly increasing, making the development of brush drums with superior performance of great significance.
[0003] Existing technologies have specifically developed some brush drums for ceramic fiber polishing machines. For example, Chinese patent with announcement number "CN220846689U" discloses "a type of assembled polishing machine brush roller". The push-pull cylinder can push and pull the top cylinder to slide along the polishing roller, so that the top cylinder can be inserted or pulled out inside the sleeve, which facilitates the disassembly and assembly of abrasive filaments and avoids the user having to manually remove the polishing roller from the polishing machine and reinstall it, thus improving the convenience of disassembly and assembly.
[0004] Although the push-pull cylinder allows the top cylinder to slide along the grinding roller, enabling it to insert or withdraw from the sleeve and facilitating the installation and removal of the abrasive wire, thus avoiding the need for manual removal and reinstallation of the grinding roller from the grinding machine and improving ease of assembly and disassembly, the interaction between the slider and the top rod in this structure can lead to wear. Over time, this can cause the top block to become less effectively fixed inside the sleeve, reducing its performance in subsequent use. Utility Model Content

The end of the spring away from the rectangular groove is fixedly installed on the side of the card plate away from the card groove. The connecting rod passes through the rectangular groove through the connecting groove and extends into both sides of the movable groove.
[0011] As a preferred technical solution, a slot is provided inside the end of the connecting rod away from the card plate, and the roller is rotatably installed inside the end of the connecting rod away from the card plate through the slot. Slide grooves are provided on both sides of the push block, and an arc slope is provided at the end of the slide grooves on both sides of the sleeve.

[0017] During the sliding process of the push block, the grooves on both sides and the arc slope at one end of the sleeve are linked with the clamping plate through a connecting rod and rollers. The rollers roll within the grooves of the push block. As the push block moves, the rollers push the connecting rod along the arc slope, thereby causing the clamping plate to move within the rectangular grooves on both sides of the sliding block. The movement of the clamping plate within the rectangular grooves is controlled by a spring. When the push block pushes the rollers to move the clamping plate outward, the clamping plate can engage with the groove in the sleeve, achieving a fixed connection between the sliding block and the sleeve. Conversely, when the push block moves in the opposite direction, the spring force will cause the clamping plate to retract, releasing the engagement between the sliding block and the sleeve, effectively reducing wear and increasing the service life of the sliding block.

[0025] Example
[0026] refer to Figures 1-6 This embodiment provides a brush drum for a ceramic fiber polishing machine, comprising a brush roller body 2. Sleeves 1 are provided inside both sides of the brush roller body 2. Grooves 23 are provided on both sides of the sleeves 1. Sliding blocks 20 are slidably installed inside both sleeves 1. Connecting blocks 12 are fixedly installed at the ends of the sliding blocks 20 away from the sleeves 1. Drive motors 13 are fixedly installed inside the connecting blocks 12. A threaded rod 10 is fixedly installed on the output shaft of the drive motor 13, and a push block 9 is threadedly connected to the threaded rod 10. Both sides of the sliding block 20 are movably mounted with a clamping plate 21, which is engaged in the slot 23. The end of the clamping plate 21 close to the sliding block 20 is integrally formed with a connecting rod 28. The end of the connecting rod 28 away from the clamping plate 21 is rotatably mounted with a roller 32. The roller 32 rolls on both sides of the outer ring of the push block 9. The end of the connecting block 12 away from the sliding block 20 is fixedly mounted with a grinding roller 4. The end of the connecting block 12 close to the grinding roller 4 is fixedly mounted with a telescopic column 5, which is slidably mounted inside the grinding roller 4.
[0027] refer to Figures 3 to 4A pad 22 is fixedly installed at the center of the sleeve 1. The ends of the sliding blocks 20 on both sides away from the connecting block 12 are attached to the pad 22. A movable groove 7 is opened inside the sliding block 20. The push block 9 is slidably installed inside the movable groove 7. A motor groove 11 is opened inside the connecting block 12. The drive motor 13 is fixedly installed inside the connecting block 12 through the motor groove 11. The threaded rod 10 is rotatably installed inside the movable groove 7 by passing through one side of the movable groove 7. An internal threaded hole 24 is opened at the center of the push block 9. The threaded rod 10 is threadedly connected to the push block 9 through the internal threaded hole 24. Rectangular grooves 30 are opened on both sides of the sliding block 20. Springs are fixedly installed on both sides of the rectangular grooves 30. Spring 27, the end of spring 27 away from rectangular groove 30 is fixedly installed on the side of clamping plate 21 away from clamping groove 23. Connecting rod 28 passes through rectangular groove 30 through connecting groove 29 and extends into both sides of movable groove 7. A slot 31 is opened in the end of connecting rod 28 away from clamping plate 21. Roller 32 is rotatably installed in the end of connecting rod 28 away from clamping plate 21 through slot 31. Sliding grooves 25 are opened on both sides of pushing block 9. An arc slope 26 is provided at the end of the two sliding grooves 25 near sleeve 1. Roller 32 rolls on both sides of pushing block 9 through sliding groove 25. During the sliding process of pushing block 9, the sliding grooves 25 on both sides and the arc slope 26 at the end near sleeve 1 are linked with clamping plate 21 through connecting rod 28 and roller 32. Roller 32 rolls within the groove 25 of push block 9. As push block 9 moves, roller 32 pushes connecting rod 28 along arc slope 26, thereby causing clamping plate 21 to move within rectangular grooves 30 on both sides of sliding block 20. The movement of clamping plate 21 within rectangular grooves 30 is controlled by spring 27. When push block 9 pushes roller 32 to move clamping plate 21 outward, clamping plate 21 can engage with groove 23 in sleeve 1, achieving a fixed connection between sliding block 20 and sleeve 1. Conversely, when push block 9 moves in the opposite direction, the elastic force of spring 27 will cause clamping plate 21 to retract, releasing the engagement between sliding block 20 and sleeve 1, effectively reducing wear and increasing the service life of sliding block 20.
[0028] refer to Figures 2 to 3 The grinding roller 4 has a storage groove 14 at its center. The telescopic column 5 slides inside the grinding roller 4 through the storage groove 14. Square grooves 16 are provided on both the upper and lower sides of the grinding roller 4. Telescopic cylinders 15 are fixedly installed inside the square grooves 16. The output shafts of the telescopic cylinders 15 are fixedly installed on the upper and lower sides of the connecting block 12, which makes it convenient for the telescopic column 5 to slide in the storage groove 14 inside the grinding roller 4. This allows the sliding block 20 to extend and retract within a certain range, making it convenient for the sliding block 20 to slide out from the sleeve, which facilitates the replacement of the brush roller body 2 later.
[0029] refer to Figure 2 , Figures 3 to 6The sleeve 1 has integrally formed positioning semicircles 17 on both its upper and lower sides. Each positioning semicircle 17 has a positioning hole 18. The sliding block 20 has positioning grooves 8 on both its upper and lower sides on its outer ring. The positioning semicircles 17 slide within the positioning grooves 8. Angle plates 3 are integrally formed on both the upper and lower sides of the end of the sliding block 20 furthest from the sleeve 1. Positioning rods 6 are fixedly installed on the end of the angle plates 3 closest to the sleeve 1. The positioning rods 6 are slidably installed inside the positioning holes 18. The positioning grooves 8 on the upper and lower sides of the outer ring of the sliding block 20 and the positioning rods 6 on the angle plates 3 cooperate to provide positioning and stability. The positioning semicircles 17 slide within the positioning grooves 8, and the positioning rods 6 are slidably installed through the positioning holes 18. During the adjustment of the sliding block 20, these positioning structures ensure that the sliding block 20 slides in the correct direction, preventing offset or shaking and ensuring the stability of the brush drum during operation. The pad 22, which is fixedly installed at the center of the sleeve 1, provides abutment limit for the sliding blocks 20 on both sides, so that the sliding blocks 20 can maintain a stable position after adjustment.
[0030] Operating principle and advantages: When the structure of the brush drum needs adjustment, the drive motor 13 starts, and its output shaft drives the threaded rod 10 to rotate. Since the threaded rod 10 and the push block 9 are threadedly connected through the internal threaded hole 24, according to the principle of threaded transmission, the rotation of the threaded rod 10 is converted into linear sliding of the push block 9 within the movable groove 7 inside the sliding block 20. During the sliding process of the push block 9, the sliding grooves 25 on both sides and the arc slope 26 at one end of the sleeve 1 are linked with the clamping plate 21 through the connecting rod 28 and the roller 32. The roller 32 rolls in the sliding groove 25 of the push block 9. As the push block 9 moves, the roller 32 pushes the connecting rod 28 along the arc slope 26, thereby driving the clamping plate 21 to move within the rectangular grooves 30 on both sides inside the sliding block 20. The movement of the clamping plate 21 within the rectangular groove 30 is controlled by the spring 27. When the pushing block 9 pushes the roller 32 to move the clamping plate 21 outward, the clamping plate 21 can engage with the groove 23 of the sleeve 1, achieving a fixed connection between the sliding block 20 and the sleeve 1. Conversely, when the pushing block 9 moves in the opposite direction, the elastic force of the spring 27 will cause the clamping plate 21 to retract, releasing the engagement between the sliding block 20 and the sleeve 1. The grinding roller 4, fixedly installed at the end of the connecting block 12 away from the sliding block 20, is a key component for connecting with the brush roller 4. The connecting block 12 and the grinding roller 4 are connected by a telescopic column 5 and a receiving groove 14. The telescopic column 5 is slidably installed in the receiving groove 14 inside the grinding roller 4, allowing the sliding block 20 to extend and retract within a certain range, facilitating its sliding out of the sleeve and enabling subsequent replacement of the brush roller body 2. At the same time, the telescopic cylinder 15, fixedly installed in the square grooves 16 on the upper and lower sides of the grinding roller 4, has its output shaft fixed on the upper and lower sides of the connecting block 12. The telescopic cylinder 15 facilitates the retraction of the telescopic column 5 into the receiving groove 14 inside the grinding roller 4. The positioning semicircles 17 and positioning holes 18 integrally formed on the upper and lower sides of the sleeve 1 cooperate with the positioning grooves 8 on the upper and lower sides of the outer ring of the sliding block 20 and the positioning rods 6 on the corner plate 3 to achieve positioning and stabilization. The positioning semicircles 17 slide within the inner ring of the positioning grooves 8, and the positioning rods 6 are slidably installed through the positioning holes 18. During the adjustment of the sliding block 20, these positioning structures ensure that the sliding block 20 slides in the correct direction, preventing deviation or shaking and ensuring the stability of the brush drum during operation. The abutment 22 fixedly installed at the center of the sleeve 1 provides abutment and limit for the sliding blocks 20 on both sides, allowing the sliding blocks 20 to maintain a stable position after adjustment.
