As an improvement: the lower side of the pressure plate is provided with a protective cushion.

Compared with the existing technology, the advantage of this utility model is that the motor drives the rotating shaft to rotate, and the convex threads on the outside of the rotating shaft cooperate with the gears to drive the circular mounting table and the circular grinding disc on the upper side of the elastic telescopic rod to rotate. The plastic bowls are placed into the matching plastic bowl slots on the placement plate at the same time, and are positioned through the pressure plate. The bottom of the plastic bowl is polished with a circular polishing disc to polish multiple groups of plastic bowls at the same time. The polishing efficiency is compared to manual operation. be greatly improved;

Each set of circular polishing discs corresponds to a set of plastic bowls. The circular polishing discs are elastically supported by elastic telescopic rods, which do not exert strong pressure on the bottom of the plastic bowl and will not cause damage to the bottom of the plastic bowl. Plastics with different burr lengths The bowl can be sanded at the same time.

Detailed ways

The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 to 3, a plastic bowl bottom burr grinding equipment includes a bottom frame 1 and a cover plate 11. The cover plate 11 is installed on the upper side of the bottom frame 1. The middle portion of the left and right side walls of the bottom frame 1 A rotating shaft 2 is rotatably connected between them. A motor 4 is connected to the middle of the right outer wall of the bottom frame 1 to drive the rotating shaft 2. A plurality of protruding threads 3 are evenly connected to the outside of the rotating shaft 2. On the bottom plate of the bottom frame 1 A support shaft 5 is provided at the front and rear sides of the multi-section protruding threads 3 and is rotatably connected to each other. The support shaft 5 is connected with a gear 6 that meshes with one side of the corresponding set of protruding threads 3. The support shaft 5 A circular mounting platform 7 is connected to the upper end. An elastic telescopic rod 8 is connected to the upper axis of the circular mounting platform 7. A circular polishing piece 9 is connected to the upper end of the elastic telescopic rod 8. The cover plate 11 is provided with multiple sets of matching circular grinding discs 9 passing through the circular holes 12.

Start the motor 4, and the motor 4 drives the rotating shaft 2 to rotate. The multiple sets of raised threads 3 on the outside of the rotating shaft 2 cooperate with the gear 6 to drive the support shaft 5 to rotate, thereby driving the circular mounting platform 7 to rotate, so that the elastic telescopic rod 8 moves upward. The circular polishing disc 9 on the side rotates inside the circular hole 12.
