Working principle:
[0040] Preparation work before polishing: stack the plastic shells to be polished horizontally on the M parallel metal strips of the base 1 of the bracket. Multiple plastic shells can be placed on the base 1. After stacking in a group of brackets, insert the fixing frame 2 into the slot of the U-shaped piece 3 to firmly fix the plastic shell between the base 1 and the fixing frame 2 to prevent the plastic shell from falling off or shifting during the polishing process.
[0041] Polishing treatment: After all the plastic shells are stacked and fixed, put the device into the polishing machine, turn on the polishing machine, and use the high-speed rotation of the polishing machine to drive the polishing medium to process the surface of the plastic shell; compressed air or high-speed rotating impellers accelerate the polishing material to high speed, and the high-speed polishing material is sprayed from multiple directions to the surface of the plastic shell to impact the plastic shell; the high-speed polishing material rolls randomly in the polishing chamber, so that all surfaces of the plastic shell can fully contact with the polishing material, and the plastic shell is firmly fixed in the base 1 and between the fixing frame 2, avoiding damage caused by collision between the plastic shells. At the same time, the gap between the base 1 and the fixing frame 2 allows the polishing material to pass through, realizing all-round polishing of the shell. The high-speed polishing material impacts the surface of the plastic shell, shears off protruding parts such as burrs and flash, and plastically deforms the surface to improve the surface finish. The polishing treatment of the plastic shell is completed. During the polishing process, the wheel hub 4, support plate 6, support column 5, U-shaped piece 3 and bracket play an important supporting and fixing role, which can not only withstand the collision of high-speed polishing materials, but also fix the plastic shell to prevent mutual collision; the wheel hub 4 fixes and supports the product bracket, and facilitates the placement and removal of the device in the polishing machine; the support plate 6 provides additional structural support for the bracket to prevent the bracket from deformation or breakage during polishing; the U-shaped piece 3 provides an installation and fixing position for the bracket, so that the bracket can be stably connected to the wheel hub 4; the support column 5 is used to support and fix the U-shaped piece 3.
[0042] Post-polishing processing: After polishing is completed, take out the device, open the fixing frame 2, and take out the polished plastic shell.
[0043] Then reload the new plastic shell to be polished and carry out the next round of polishing work.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
