[0029] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0030] Reference Figures 1 to 6 As shown, a handle tube grinding end mechanism is provided, including a frame 1. A positioning clamp 2 for fixing the handle tube is movably arranged on the frame 1. One end of the positioning clamp 2 is set as a grinding end 21. A sanding belt 3 is provided on one side of the grinding end 21. A plurality of rotatable rollers 4 are provided on the frame 1. The sanding belt 3 is sleeved on the outer surface of the plurality of rollers 4 to grind the handle tube.

[0031] In this embodiment, the handle tube is placed on the positioning fixture 2 and fixed. The end of the handle tube that needs to be ground faces the grinding end 21. The equipment is started, and the roller 4 drives the sanding belt 3 to move. The sanding belt 3 grinds the handle tube to achieve precise grinding. After grinding, the handle tube is removed from the positioning fixture 2 to ensure product quality requirements and improve grinding efficiency.

[0032] In one embodiment of this utility model, the roller 4 includes a first roller 41, a second roller 42, and an intermediate roller 43. A first support seat 11 is fixedly provided in the middle of the frame 1. A connector 12 is fixedly connected to the top of the first support seat 11. The intermediate roller 43 is rotatably installed at the end of the connector 12 away from the first support seat 11. The intermediate roller 43 is located on one side of the grinding end 21. A second support seat 13 is fixedly installed on one side of the frame 1. A bearing seat 14 is fixedly connected to the second support seat 13. A rotating shaft 15 is installed inside the bearing seat 14. The two ends of the rotating shaft 15 are respectively connected to the first roller 41 and the first pulley 16. A third support seat 17 is fixedly installed on the other side of the frame 1. A connecting shaft 18 is fixedly connected to the third support seat 17. A bearing is sleeved on the other end of the connecting shaft 18. The second roller 42 is sleeved on the outer surface of the bearing.

[0033] Furthermore, a motor 5 is provided at the bottom of the frame 1, and the output end of the motor 5 is connected to a second pulley 51. The second pulley 51 is connected to the first pulley 16 via a belt.

[0034] The starter motor 5 drives the second pulley 51 to rotate, which in turn drives the first pulley 16 to rotate via the belt. This, in turn, drives the rotating shaft 15 and the first roller 41 to rotate. The first roller 41 starts, which drives the sanding belt 3 to rotate. The inner side of the sanding belt 3 has no sanding effect and is connected to the first roller 41, the second roller 42 and the intermediate roller 43. The sanding belt 3 rotates continuously, causing its outer side to rub against the handle tube fixed on the positioning fixture 2, thereby performing sanding.

[0035] In one embodiment of this utility model, the third support 17 includes a support body 171 and a sliding plate 172. Two locking blocks 173 are provided on one side of the support body 171. Each locking block 173 has a sliding groove 174. The sliding plate 172 is movably disposed between the two sliding grooves 174. The sliding plate 172 is fixedly connected to the connecting shaft 18 by a locking bolt 178. A limiting member 179 is fixedly installed on the sliding plate 172. The limiting member 179 is fixedly disposed at the end of the connecting shaft 18 away from the bearing. The sliding plate 172 can slide back and forth along the length direction of the sliding groove 174, thereby adjusting the tightness of the sanding belt 3. The locking bolt 178 can lock and fix the connecting shaft 18. At the same time, the limiting member 179 can prevent the second roller 42 from shifting during rotation when adjusting the verticality. Loosening the locking bolt 178 can adjust the verticality of the second roller 42, and then locking it again.

[0036] Furthermore, slots 1721 are provided on both sides of the sliding plate 172, and a connecting block 175 is fixedly installed on one side of the support body 171. A threaded hole is provided on the connecting block 175, and the threaded hole is threadedly connected to the bolt 176. One end of the bolt 176 is provided with a locking block 177 that cooperates with the slot 1721. Rotating the bolt 176 can adjust the position of the sliding plate 172, thereby adjusting the tightness of the sanding belt 3.

[0037] In one embodiment of this utility model, the positioning clamp 2 includes an upper fixing block 22 and a lower fixing block 23. The upper fixing block 22 is vertically and vertically positioned above the lower fixing block 23. The bottom of the lower fixing block 23 is provided with a mounting plate 24, which is connected to a connecting column 25. The other end of the connecting column 25 is fixedly connected to a sliding plate 26. A slider 27 is fixedly installed at the bottom of the sliding plate 26. A fixing plate 28 is fixedly positioned on the frame 1. Guide rails 29 are symmetrically arranged on the top of the fixing plate 28. The slider 27 is movably positioned on the guide rails 29.

[0038] Furthermore, a cylinder 6 is fixedly connected to the top of the upper fixed block 22 so that the upper fixed block 22 can be raised and lowered.

[0039] Start cylinder 6 to move upper fixed block 22 upward, placing the handle tube to be ground onto lower fixed block 23. Then, move upper fixed block 22 towards lower fixed block 23 to press and fix the handle tube. The operator pushes mounting plate 24 or sliding plate 26 to move the end of the handle tube to be ground towards sanding belt 3 for grinding. Slider 27 slides along the length of guide rail 29. After grinding is completed, it moves away from sanding belt 3 to open upper fixed block 22, thereby removing the handle tube and completing the grinding. The function of connecting post 25 is to match the height position of sanding belt 3.

[0040] Preferably, limit blocks 20 are fixedly installed at both ends of the fixed plate 28 to limit the sliding range of the slide plate 26 and prevent it from sliding off the guide rail 29.

[0041] In one embodiment of this utility model, a protective cover 7 is provided on the outside of the sanding belt 3 and several rollers 4 to ensure the personal safety of the operator.

[0042] In one embodiment of this utility model, a control box 8 is provided at the bottom of the frame 1 to control the switching and other operations of the entire equipment.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
