Description

Technical Field

[0001] This utility model relates to the technical field of polishing devices, specifically a polishing device for the production of washing machine parts. Background Technology

[0002] Washing machine parts are essential components of a washing machine, forming its various parts. They are primarily manufactured using injection molding, which results in a rougher surface that requires polishing. Polishing removes some of the oxide layer, making the parts harder, increasing their smoothness, and improving their appearance. A smooth surface also discourages bacterial growth.

[0003] In the traditional manufacturing process of washing machine parts, only one side of the part can be polished at a time. After polishing one side, workers need to flip the part over and polish the other side, which increases the workload of workers and reduces the efficiency of part polishing. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for the production of washing machine parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for producing washing machine parts, comprising: a base plate, a side plate vertically fixedly installed on the upper end of the base plate, a rotating roller connected to one side of one end of the side plate on all four sides, a grinding belt being drivenly connected to the outer wall of the two horizontal rotating rollers, and a sliding groove being opened on the left and right sides of one end of the side plate, with a slider slidably connected to the upper and lower ends of each sliding groove.

[0006] Each slider has a rotating roller 2 rotatably connected to one end, which is located inside the grinding belt. The other end of the slider passes through the groove. The other ends of the two horizontal sliders are fixedly installed with connecting plates. A threaded rod is threadedly connected between the two connecting plates. The threaded rod is rotatably connected to the outer wall of the side plate through the ear plate.

[0007] Preferably, one end of each of the two rollers passes through the side plate and is fixedly mounted with a pulley, a motor is fixedly mounted on the outer wall of one end of the side plate, a pulley is fixedly mounted on the output end of the motor, and a belt is used to drive the pulley and the pulley.

[0008] Preferably, a limiting ring 1 is fixedly installed on the inner outer wall of each of the rollers 1, a groove is opened at the outer end of each roller 1, and a limiting ring 2 is provided at the outer end of each roller 1. A protrusion is fixedly installed at the center of one end of the limiting ring 2, and the protrusion is inserted into the groove and fixed by bolts.

[0009] Preferably, there are two ear plates, which are fixedly installed on the upper and lower sides of one end of the side plate respectively. The threaded rod is rotatably connected between the two ear plates through a bearing, and the upper end of the threaded rod passes through the ear plate and is fixedly installed with a throttle handle.

[0010] Preferably, the threaded rod has external threads at both the upper and lower ends, and the external threads at the upper and lower ends are symmetrically arranged.

[0011] Preferably, a threaded sleeve is fixedly installed at the middle of each connecting plate, and the threaded sleeve penetrates the side wall of the connecting plate.

[0012] Preferably, the two threaded sleeves are symmetrically threaded onto the outer walls of the upper and lower ends of the threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves first attaching a polishing belt to the outer end of a rotating roller, then installing a limit ring 2 on the outer end of the rotating roller. Next, rotating the handle drives all four rotating rollers 2 to move outward simultaneously, pushing the two polishing belts outward and taut them. Then, starting the motor drives the two polishing belts to rotate. The washing machine parts that need to be polished are inserted at an angle between the two polishing belts, and then the washing machine parts are gradually rotated until the upper and lower ends of the washing machine parts come into contact with the two polishing belts respectively, thus polishing both the upper and lower ends of the washing machine parts simultaneously. This reduces the workload of workers and improves polishing efficiency. Attached Figure Description
