DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 3 , the utility model provides a technical solution:

[0024] A polishing device for a housing of a household appliance comprises an active roller 1 and two groups of driven rollers 2. The active roller 1 is rotatably mounted on a mounting frame 3. The active roller 1 and the two groups of driven rollers 2 are connected by a sanding belt 4. The active roller 1 is matched with the output end of a first motor 11 in a transmission manner. The first motor 11 is fixedly mounted on the top surface of the mounting frame 3. By arranging the active roller 1, the driven roller 2 and the sanding belt 4 can be driven to rotate, so that the sanding belt 4 can rotate and polish the housing of the household appliance.

[0025] It also includes an adjusting component, which includes an adjusting rod 5. A spring 6 is slidably sleeved on the surface of the adjusting rod 5. One end of the spring 6 is in contact with the sliding sleeve 7. The sliding sleeve 7 is slidably matched with the adjusting rod 5. The sliding sleeve 7 is fixedly connected to the rotating shaft 8. The rotating shaft 8 is rotatably matched with the driven roller 2. By arranging the sliding sleeve 7 and the rotating shaft 8, the driven roller 2 can be driven to slide on the adjusting rod 5 while ensuring its normal rotation, thereby changing the distance between the two groups of driven rollers 2 and the length of the sand belt 4, so that the sand belt 4 between the two groups of driven rollers 2 can fit on the curved surface and the rounded edge; a limiting plate 12 is fixedly installed on one end of the adjusting rod 5, and the other end of the adjusting rod 5 is fixedly connected to the mounting frame 3. The other end of the spring 6 is fixedly connected to the mounting frame 3. The limiting plate 12 can prevent the sliding sleeve 7 from falling off the adjusting rod 5.

[0026] The movable assembly also includes a screw rod 9, a movable seat 10 is installed on the surface of the screw rod 9, one side of the movable seat 10 is fixedly connected to the mounting frame 3, the top of the screw rod 9 is rotatably matched with the top plate 13, a second motor 14 is fixedly installed on the top surface of the top plate 13, the output end of the second motor 14 is transmission matched with the screw rod 9, the bottom of the screw rod 9 is rotatably mounted on the bottom plate 15, and the bottom plate 15 is fixedly connected to the top plate 13 through a support plate 16. The movable assembly also includes a limit rod 17, the limit rod 17 is slidably matched with the mounting frame 3, the top of the limit rod 17 is fixedly installed on the top plate 13, and the bottom of the limit rod 17 is fixedly installed on the bottom plate 15. By setting the movable assembly, the sanding belt 4 can be driven to move up and down, so as to polish different positions of the home appliance housing, thereby improving the processing efficiency, and by setting the limit rod 17, the mounting frame 3 and the movable seat 10 can be prevented from rotating, so as to ensure that when the screw rod 9 rotates, the mounting frame 3 can drive the sanding belt 4 and other structures to move up and down normally, and at the same time, the stability during movement can be improved.

[0027] When in use, the device is moved to a designated position, the bottom plate 15 is fixed, and the first motor 11 is started. The output end of the first motor 11 drives the active roller 1 to rotate, and the active roller 1 drives the sanding belt 4 and the two sets of driven rollers 2 to rotate. The surface of the housing of the home appliance to be polished is brought close to the sanding belt 4 between the two sets of driven rollers 2, and the rotating sanding belt 4 polishes the surface of the housing of the home appliance; when polishing the curved surface and the rounded edge, the housing of the home appliance can be moved so that it applies a certain pressure to the sanding belt 4 between the two sets of driven rollers 2, and the sanding belt 4 will The pressure is transmitted to the driven roller 2, and the driven roller 2 drives the sliding sleeve 7 to slide on the adjusting rod 5 through the rotating shaft 8, so that it compresses the spring 6 and approaches the active roller 1. The sliding of the sliding sleeve 7 shortens the distance between the driven roller 2 and the active roller 1 and the sanding belt 4. At the same time, the distance between the two groups of driven rollers 2 becomes smaller and the sanding belt 4 becomes longer. At the same time, the compressed spring 6 pushes the sliding sleeve 7 to tighten the sanding belt 4 between the driven rollers 2 and fit it to the surface of the home appliance shell, thereby grinding the curved surface and rounded edges of the home appliance shell.
