Description

Technical Field

[0001] This utility model relates to the field of wood brush handle processing, and in particular to a device for polishing the rough edges of wood brush handles. Background Technology

[0002] Wooden brushes are a very practical household item. A wooden brush consists of a brush head and a wooden handle. After the workpiece is cut and shaped, the surface of the wooden brush handle often has defects such as burrs and wood fibers curling up. It is necessary to use a polishing device to polish the wooden brush handle.

[0003] A search of Chinese patents revealed publication number CN213136204U, which discloses a brush handle polishing device. The device includes a base, with a motor fixedly connected to the top of the base. A drive shaft of the motor passes through the top of the base and is fixedly connected to a rotating shaft. A brush handle groove is fixedly connected to the top of the rotating shaft. A water collection tank is provided on the top of the base, and a bracket is provided on the top of the water collection tank. The bracket has an annular cross-section, and its bottom is fixedly connected to the water collection tank. An operating ring is fixedly connected to the top of the bracket, and several fixing blocks are fixedly connected to the outer wall of the operating ring. This utility model's brush handle polishing device includes a clamping plate, a connecting rod, a polishing disc, a buckle plate, fixing blocks, and a motor. When polishing the brush handle, the side of the buckle plate furthest from the operating ring is smoothly aligned with the top of the fixing blocks, and the motor is started to polish the brush handle. The structure is simple and flexible, facilitating adjustment of the polishing position of the abrasive and the brush handle, making it very convenient and practical, and improving the polishing speed for different positions of the brush handle.

[0004] Existing polishing devices are not suitable for polishing the curved handle. Generally, when polishing wooden brush handles, these devices can only polish the handle itself, requiring manual sanding of the curved area, which is cumbersome, increases workload, reduces efficiency, and is inconvenient to use. Furthermore, it is difficult to replace the sanding belt. Since the sanding belt is mounted on a belt abrasive disc secured with bolts, replacement requires tools, which is cumbersome and further increases workload. To address these problems, we propose a device for polishing the rough edges of wooden brush handles. Utility Model Content

[0005] The purpose of this invention is to provide a device for polishing the rough edges of wooden brush handles, which has the advantages of facilitating polishing of curved handles and facilitating the replacement of sanding belts.

Then, the wooden brush handle is fed to the space between the first clamping head 26 and the second clamping head 29 via the feeding device. Next, the fourth cylinder 27 drives the movable plate 28 to move the second clamping head 29, clamping the wooden brush handle. Then, the third cylinder 22 drives the U-shaped frame 21 to move towards the polishing sanding belt 35. During this movement, the first motor 25 rotates, driving the first clamping head 26 to rotate, which in turn rotates the wooden brush handle, moving it to the polishing sanding belt 35 for polishing. During polishing, the first cylinder 26 is controlled by the PLC. The coordinated action of the second cylinder 8 and the third cylinder 22 causes the first cylinder 4 to move the moving plate 3, which in turn moves the rotating plate 6. The rotating plate 6 causes the second fixed plate 31 to move the second motor 32, which in turn moves the first sanding disc 33 and the second sanding disc 34, causing the polishing sanding belt 35 to move and polish the wooden brush handle. When the polishing sanding belt 35 moves to the bend of the handle, the second cylinder 8 moves the fixed rod 7, which in turn moves the rotating plate 6, so that the polishing angle of the polishing sanding belt 35 is consistent with the angle of the bend of the wooden brush handle, thus polishing the bend of the wooden brush handle and facilitating the polishing of the bend of the wooden brush handle.

[0043] When replacing the polishing belt 35, move the pull block 37. The movement of the pull block 37 drives the transmission rod 16 to move, which in turn drives the fixing head 17 to move, disengaging the fixing head 17 from the fixing groove 18. Then, move the second sanding belt disc 34 upward to disengage the polishing belt 35 from the second sanding belt disc 34. Remove the polishing belt 35 and install the new polishing belt 35 on the surface of the first sanding belt disc 33 and the second sanding belt disc 34. Reset the second sanding belt disc 34, which tightens the polishing belt 35. Then, release the pull block 37. Under the action of the spring 20, the transmission rod 16 drives the fixing head 17 to insert into the fixing groove 18 and fix it, completing the replacement and facilitating the replacement of the polishing belt 35.
