DETAILED DESCRIPTION OF THE EMBODIMENTS
[0026] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0027] In the embodiment, it is given by Figures 1-4 A grinding device for processing plastic shells. The utility model includes a processing table 1 and a mounting plate 4. A support plate 2 is fixedly connected to the top of the processing table 1. Four grinding discs 3 are rotatably connected to the rear side of the support plate 2 and are distributed in a linear array. The number of mounting plates 4 is four and they are distributed in a linear array. A first motor 5 is fixedly connected to the outside of each of the four mounting plates 4. The output shaft of the first motor 5 is fixedly connected to a bidirectional threaded rod 6 that is rotatably connected to the inside of the mounting plate 4. The outside of the bidirectional threaded rod 6 is threadedly connected to an inner clamping plate 7 that is slidably connected to the inside of the mounting plate 4. The outside of the central axes of the two left grinding discs 3 and the two right grinding discs 3 are both drivingly connected to a first conveyor belt 8. The outside of the central axes of the two middle grinding discs 3 is drivingly connected to the same second conveyor belt 9. A second motor 10 whose output shaft is fixedly connected to the central axis of one grinding disc 3 is fixedly connected to the front side of the support plate 2.
[0028] At the same time, place four plastic shells outside the inner clamping plate 7, start the first motor 5, so that the bidirectional threaded rod 6 rotates, and then drive the inner clamping plate 7 to approach the ends of the plastic shells, so as to support the inside of the plastic shells, thus completing the fixation of the plastic shells. And the inner clamping plate 7 supports the inside of the plastic shells to prevent the grinding discs 3 from applying pressure to the plastic shells and causing deformation. By starting the second motor 10, the second conveyor belt 9 is transmitted, and then drive the two first conveyor belts 8 to be transmitted, so that all four grinding discs 3 rotate, and the four fixed plastic shells can be ground simultaneously.
[0029] Specifically, referring to Figure 1 and Figure 4 , the second conveyor belt 9 is located in front of the first conveyor belt 8. A slide rail 11 is fixedly connected to the top of the processing table 1. A sliding plate 12 is slidably connected to the inside of the slide rail. A connecting shell 13 is rotatably connected to the top of the sliding plate 12. An electric push rod 14 is fixedly connected to the inside of the connecting shell 13. The output end of the electric push rod 14 is fixedly connected to the mounting plate 4.
[0030] In this embodiment, start the electric push rod 14, and the electric push rod 14 extends outwards, so that the mounting plate 4 moves upwards, and the plastic shell on the top of the mounting plate 4 moves upwards, so that the grinding discs 3 grind the outside of the plastic shell more thoroughly.
[0031] Specifically, referring to Figure 1 , a third motor 15 is fixedly connected to the top of the sliding plate 12. The output shaft of the third motor 15 is fixedly connected to a rotating column 16. A worm 17 is fixedly connected to the outside of the rotating column 16. A worm gear 18 that meshes with the worm 17 is fixedly connected to the outside of the connecting shell 13.
[0032] In this embodiment, by starting the third motor 15, the rotating column 16 rotates, which in turn drives the worm 17 to rotate, and then drives the worm wheel 18 to rotate. Subsequently, the electric push rod 14 rotates through the connecting shell 13, causing the electric push rod 14 to drive the plastic shell on the upper side of the mounting plate 4 to first rotate 360 degrees clockwise for grinding, and then rotate 360 degrees counterclockwise for grinding, so that the plastic shell is ground more evenly and thoroughly.
[0033] Specifically, referring to Figure 1 , a cylinder 19 is fixedly connected to the top of the processing table 1, and the output end of the cylinder 19 is fixedly connected to the outside of the sliding plate 12.
[0034] In this embodiment, the cylinder 19 is started, so that the cylinder 19 stretches outwards, causing the sliding plate 12 to slide towards the support plate 2 end. After one end of the plastic shell on the top of the mounting plate 4 is ground, the cylinder 19 drives the sliding plate 12 to slide backwards, and then the outside of the plastic shell is presented on the outside of the grinding disc 3 for grinding.
[0035] Specifically, referring to Figure 1 and Figure 2 , a sliding wheel 20 is fixedly connected to the bottom of the sliding plate 12, and a sliding groove 21 that is slidably connected to the outside of the sliding wheel 20 is formed in the top of the processing table 1.
[0036] In this embodiment, when the sliding plate 12 slides on the top of the processing table 1, it drives the sliding wheel 20 to slide inside the sliding groove 21, thereby supporting the sliding of the sliding plate 12 and making the sliding of the sliding plate 12 more stable.
[0037] Specifically, referring to Figure 1 and Figure 2 , a control panel 22 is fixedly connected to the top of the processing table 1, and a slider that is slidably connected to the inside of the slide rail 11 is fixedly connected to the bottom of the sliding plate 12.
[0038] In this embodiment, the control panel 22 controls the clamping, rotation, grinding, etc. of the plastic shell. The sliding plate 12 slides inside the slide rail 11, so that the plastic shell on the top of the mounting plate 4 can slide outside the grinding disc 3, making the grinding more thorough.
[0039] Working principle:
[0040] First: Place four plastic shells on the outside of the inner clamping plate 7 at the same time, start the first motor 5, so that the bidirectional threaded rod 6 rotates, and then drive the inner clamping plate 7 to approach the end of the plastic shell, so as to support the inside of the plastic shell, thus completing the fixation of the plastic shell. And the inner clamping plate 7 supports the inside of the plastic shell to prevent the grinding disc 3 from applying pressure to the plastic shell and deforming it. By starting the second motor 10, the central axis of one grinding disc 3 drives the second conveyor belt 9 to drive, and then the two grinding discs 3 drive the two first conveyor belts 8 to drive, so that all four grinding discs 3 rotate, and the four fixed plastic shells can be ground simultaneously;
[0041] Then: Start the electric push rod 14. The electric push rod 14 extends outwards to move the mounting plate 4 upwards, and move the plastic shell on the top of the mounting plate 4 upwards, so that the grinding disc 3 can grind the outside of the plastic shell more thoroughly. Start the cylinder 19, so that the cylinder 19 stretches outwards, make the sliding plate 12 slide towards the end close to the support plate 2. After one end of the plastic shell on the top of the mounting plate 4 is ground, the cylinder 19 drives the sliding plate 12 to slide backwards, and then present the outside of the plastic shell on the outside of the grinding disc 3 for grinding.
