[0023] Reference Figure 1 A grinding device includes a material holding mechanism 10 and a grinding mechanism 40. The material holding mechanism 10 is used to clamp the workpiece and drive multiple workpieces to rotate at a uniform speed in the same direction. The workpieces are ground by the grinding mechanism 40.

[0024] Reference Figures 2-4The material holding mechanism 10 includes a roller drive assembly 15 and two roller groups that can move closer to or further away from each other. The roller groups are mounted on a material holding bracket 13. Optionally, the material holding bracket 13 is provided with a protective shell 16 to cover the roller groups and prevent workers from accidentally touching them during operation. Optionally, the material holding bracket 13 is also provided with a clamping drive part 14, which is connected to at least one of the roller groups to drive the two roller groups to move closer to or further away from each other. The clamping drive part 14 can be a cylinder or other structure that can achieve the same effect. The roller drive assembly 15 is connected to at least one of the roller groups, namely a first roller group 11 and a second roller group 12. Each roller group includes multiple rollers whose roller axes are located in the same straight line and are arranged at equal intervals. The lines connecting the roller axes of the two roller groups are parallel to each other. A material holding space is formed between two adjacent rollers in the first roller group 11, and each roller in the second roller group 12 is located above its respective material holding space. During loading, the clamping drive unit 14 drives the second roller group 12 to rise, increasing the height of the holding space. After the workpiece is fed into each holding space of the holding mechanism 10, the clamping drive unit 14 drives the second roller group 12 to descend until the rollers of the second roller group 12 contact the workpiece in the holding space, ensuring that the workpiece will not detach during processing. The roller drive assembly 15 drives the roller group to rotate, thereby causing the workpiece to rotate in the holding space, ensuring that the end of the workpiece can be uniformly sharpened by the grinding mechanism 40. During unloading, the clamping drive unit 14 drives the second roller group 12 to rise again so that the processed workpiece can be unloaded. Optionally, the clamping drive unit 14 can be a cylinder.

[0025] In some embodiments, the rollers of the first roller group 11 are provided with circumferential grooves on their sides, and the rollers of the second roller group 12 are adapted to the grooves. When the work material is fed into the holding space, the two roller groups move closer to each other, and the rollers in the second roller group 12 can extend into the grooves of the first roller group 11, thereby reducing the possibility of the work material deviating from or even leaving the holding space.

[0026] Optionally, the outer side of the rollers in the roller assembly is wrapped with a rubber wear-resistant layer, which reduces the possibility of materials leaving the holding space, lowers the maintenance cost of the roller assembly, and avoids the need for frequent roller replacements.

[0027] In some embodiments, the material holding mechanism 10 includes a drive shaft assembly 153, with each drive shaft of the drive shaft assembly 153 corresponding to a roller of the first roller assembly 11. The roller drive assembly 15 includes a motor 151 and a drive belt 152. The motor 151 is connected to one of the drive shafts, driving the drive shaft and the corresponding roller to rotate. The drive belt 152 is mounted on the drive shaft assembly 153 and contacts the drive shafts in the drive shaft assembly 153, thereby driving all drive shafts to rotate in the same direction and at the same speed. This ensures that the material in the material holding space rotates at a uniform speed, avoiding deviation of the material due to different speeds, which could affect processing accuracy. Optionally, the motor 151 is connected to one of the drive shafts via a belt drive assembly. A support wheel assembly 154 is provided below the drive shaft assembly 153, and the drive belt 152 is disposed between the drive shaft assembly 153 and the support wheel assembly 154. The support wheel assembly 154 ensures that the drive belt 152 and the drive shafts in the drive shaft assembly 153 are in taut contact, ensuring that the rotational speed of the drive shaft assembly 153 is consistent. Furthermore, a movable adjusting wheel 155 is provided below the support wheel assembly 154. The transmission belt 152 is tensioned and installed on the outside of the support wheel assembly 154 and the adjusting wheel 155. The tension of the transmission belt 152 can be adjusted by adjusting the position of the adjusting wheel 155. The transmission belt 152 is tensioned on the outside of the support wheel assembly 154 and the adjusting wheel 155. The top surface of the transmission belt 152 is located between the transmission shaft assembly 153 and the support wheel assembly 154. The line connecting the center of the transmission shaft of the transmission shaft assembly 153 is parallel to the line connecting the center of the wheel of the support wheel assembly 154.

[0028] In some embodiments, the material holding mechanism 10 further includes a base plate 17, which is fixed to the material holding bracket 13, and the rollers of the roller assembly are rotatably mounted on the base plate. The surface of the base plate used to mount the roller assembly forms the side of the material holding space, allowing one end of the workpiece to abut against the base plate, thereby ensuring that the other end of the workpiece is flush and the grinding degree is uniform and controllable. As an optional embodiment, the base plate is made of a wear-resistant material. As another optional embodiment, the base plate is provided with wear-resistant blocks corresponding to the material holding spaces. During grinding, one end of the workpiece can abut against the wear-resistant block to make the ends of each workpiece in the material holding space flush to ensure consistent processing. When the wear-resistant block wears out, the corresponding wear-resistant block can be replaced, without replacing the entire base plate, thus reducing maintenance costs.

[0029] Reference Figure 5 The grinding mechanism 40 includes a grinding wheel tip mechanism 41 and a position adjustment mechanism. The grinding wheel tip mechanism 41 is mounted on the worktable through the position adjustment mechanism. By adjusting the position adjustment mechanism, the relative position of the grinding wheel tip mechanism 41 with respect to the workpiece of the material holding mechanism 10 on the processing station can be changed, thereby adapting to different processing requirements.

[0030] In some embodiments, the position adjustment mechanism includes a telescopic component 42, which can extend and retract along the height direction and be fixed. The grinding wheel tipping mechanism 41 is mounted on the telescopic component 42, and the height of the grinding wheel tipping mechanism 41 relative to the worktable can be adjusted by adjusting the telescopic component 42, thereby adjusting the longitudinal position of the grinding wheel tipping mechanism 41 relative to the workpiece.

[0031] In some embodiments, the position adjustment mechanism includes an angle adjustment component 43, which includes a bracket 431, a spiral mounting bracket 432, and a spiral adjustment knob 433. Both the spiral adjustment knob 433 and the spiral mounting bracket 432 are rotatably mounted on the bracket 431. A grinding wheel tipping mechanism 41 is mounted on the spiral mounting bracket 432. The outer edge of the spiral mounting bracket 432 has teeth, and the spiral adjustment knob 433 meshes with the teeth of the spiral mounting bracket 432. By rotating the spiral adjustment knob 433, the spiral mounting bracket 432 rotates relative to the bracket 431, thereby adjusting the relative angle between the grinding wheel tipping mechanism 41 on the spiral mounting bracket 432 and the workpiece of the material holding mechanism 10. Optionally, the spiral mounting bracket 432 has an arc-shaped through hole, and the bracket 431 has a corresponding arc-shaped threaded groove. When fixing the relative position of the spiral mounting bracket 432 and the bracket 431, a bolt can be passed through the through hole and inserted into the threaded groove for tightening.

[0032] Optionally, the bracket 431 can be mounted on the telescopic component 42, thereby allowing adjustment of the grinding wheel tip mechanism 41 in both height and angle to better adapt to different processing requirements.

[0033] Optionally, the bracket 431 is also provided with an angle scale, and the screw mounting bracket 432 is correspondingly marked. The angle scale is aligned with the outer edge of the screw mounting bracket 432 so that the operator can make accurate fine adjustments and record operating data.

[0034] In some embodiments, the grinding mechanism 40 further includes a grinding sensor 44 for detecting the position of the material holding mechanism 10, and the grinding sensor 44 is electrically connected to the grinding wheel tip mechanism 41. When the grinding sensor 44 detects that the material holding mechanism 10 is about to reach the processing station, the grinding sensor 44 sends an electrical signal to the grinding wheel tip mechanism 41 to start the grinding wheel tip mechanism 41; when the material holding mechanism 10 leaves the processing station, the grinding sensor 44 sends an electrical signal again to shut down the grinding wheel tip mechanism 41.
