[0002] Sanding machines, also known as brush machines, are often used to sharpen various cutting tools, as well as to perform surface cleaning tasks such as grinding and deburring parts.

[0003] The sanding machine mainly consists of a bracket, a brush plate, a motor, and a drive pulley assembly. When in use, the motor drives the brush plate to rotate through the drive pulley assembly. During the rotation, the brush plate grinds the tool or part to be processed, thereby achieving the effect of surface cleaning. When the sanding machine is in use, a lot of dust will be generated. In order to prevent the dust from being raised, a dust cover is usually installed on the outside of the sanding machine.

[0004] When the above-mentioned sanding machine is in use, the brush disc of the sanding machine is easily worn out, and the operator needs to regularly inspect and replace it. During the inspection and replacement, the operator needs to remove the dust cover, which is complicated and inconvenient for the inspection and replacement of the sanding machine.

An inspection door 3 is provided in the slide groove, and the inspection door 3 is slidably connected to the second slide rail 152, and the sliding axis is horizontally arranged. It should be noted that there is a certain friction between the inspection door 3 and the second slide rail 152, so that the inspection door 3 can remain stationary on the second slide rail 152 without shaking when not affected by external forces.

[0041] Reference Figure 3 and Figure 4The brush plate quick-change mechanism on the sanding machine includes a horizontal mounting frame 2. First slide rails 111 made of channel steel are fixedly mounted on both sides of the mounting frame 2. The drive pulley assembly 12, brush plate body 13, and motor 14 are all mounted on the mounting frame 2. A handle 22 is fixedly mounted on one end of the mounting frame 2 near the inspection port 151.

[0042] The bracket 11 is provided with a plurality of pulleys 21. The pulleys 21 are divided into two groups and are arranged horizontally. The two groups of pulleys 21 are located on either side of the mounting frame 2 and correspond to the two first slide rails 111. The pulleys 21 are rotatably connected to the bracket 11. The pulleys 21 are located in the grooves of the first slide rails 111 and cooperate with the first slide rails 111. The mounting frame 2 and the bracket 11 are slidably connected via the pulleys 21 and the first slide rails 111, and the sliding axis is arranged horizontally.

[0043] Reference Figure 5 and Figure 6 , a limit assembly 4 is provided on the bracket 11, and the limit assembly 4 includes a first limit block 41, a second limit block 44, a mounting block 42 and a limit latch 43. The first limit block 41 and the second limit block 44 are both fixedly provided on the first slide rail 111, the first limit block 41 is located at the end of the first slide rail 111 away from the inspection port 151, and the second limit block 44 is located at the end of the first slide rail 111 close to the inspection port 151.

[0045] The implementation principle of the brush plate quick-change structure on a sanding machine in the embodiment of the present application is as follows:

[0046] When inspecting and replacing the brush disc on the sanding machine, the operator pulls the inspection door 3 to make the inspection door 3 slide on the second slide rail 152 away from the inspection port 151. Then, the operator holds the handle 22 and pulls the mounting bracket 2 in the direction close to the inspection port 151 to make the first slide rail 111 slide relative to the pulley 21, so that the mounting bracket 2 slides out from the dust cover 15. When the mounting bracket 2 is completely pulled out of the inspection port 151, the limiting latch 43 is arranged opposite to the first limiting groove 411. The operator inserts the limiting latch 43 into the first limiting groove 411 to fix the mounting bracket 2 to the bracket 11. Then, the operator inspects and replaces the brush disc body 13. When replacing 13, the operator disassembles the brush disc body 13 and the coupling 5 by bolts, and then fixes the new brush disc body 13 on the coupling 5 by bolts. After the installation is completed, the operator pulls out the limit latch 43 to cancel the fixation of the mounting frame 2 and the bracket 11, and then pushes the mounting frame 2 to slide horizontally toward the inside of the dust cover 15. When the mounting frame 2 slides completely to the inside of the dust cover 15, the limit latch 43 is aligned with the second limit groove 441. The operator inserts the limit latch 43 into the second limit groove 441 to fix the mounting frame 2 and the bracket 11, and finally pushes the inspection door 3 to slide to the inspection port 151, and the brush disc of the sander is repaired and replaced.
