[0036] The working principle of this utility model is as follows: When in use, the staff opens the housing 1, puts the mobile phone frame that needs to be polished into the mobile phone frame fixing plate 29, the cylinder 6 pushes the connecting rod 5, so that the pressure plate 8 presses on the mobile phone frame fixing plate 29, and at this time the power is turned on, and this utility model starts to work.

[0037] After the power is turned on, the output of the second motor 31 drives the second rotating shaft 26 to rotate slowly counterclockwise. The second rotating shaft 26 drives the turntable 28 to rotate slowly, the turntable 28 drives the phone frame fixing plate 29 to rotate slowly, and the phone frame fixing plate 29 drives the second baffle 30 to rotate slowly.

The rotating barrel drives the T-slot 16, the T-slider 17, the first rotating shaft 18, and the spring 19 to rotate. The first rotating shaft 18 drives the grinding wheel 22 to rotate rapidly. The grinding wheel 22 first polishes the phone frame because the phone frame... The reason why the fixed plate 29 rotates slowly is that when one corner of the phone frame is about to contact the grinding wheel 22, the grinding wheel will be pushed away a little distance due to the action of the first baffle 23 and the second baffle 30, reducing the pressure of the grinding wheel on the corner of the frame. After the corner slowly passes the grinding wheel 22, due to the previous pushing force, the spring 19 pushes the first rotating shaft 18 and the T-shaped slider 17 to gradually return to their original positions. The phone frame is polished repeatedly. At the same time, the water pump 33 draws water through the water inlet pipe 34 at the input end, flows into the water supply pipe 35 through the output end, and finally sprays it from the nozzle 36 to the position where the phone frame contacts the grinding wheel 22. The sewage mixed with debris will be filtered through the water filter hole 37 and then fall into the water outlet pipe 38 and flow out from the water outlet 39.

[0038] After sanding all the phone frame edges that need sanding, turn off the power, and this utility model will stop working.
