Abstract
Description
Technical Field
[0001] This invention relates to the field of plastic product demolding technology, and more specifically, to a plastic product demolding and polishing device. Background Technology
[0002] After plastic products are demolded, parting lines, burrs, or minor imperfections often remain on the surface, requiring polishing and grinding techniques to improve the smoothness. However, manual polishing using handheld power tools is generally inefficient and inconsistent, and complex curved surfaces are difficult to process evenly. Furthermore, during the processing of general machines, the internal components heat up, and the generated waste cannot be cleaned up in time, which greatly affects efficiency.
[0003] Therefore, it is necessary to provide a demolding and polishing device for plastic products to solve the above problems. Utility Model Content
[0004] Based on the aforementioned problems in the existing technology, the purpose of this application is to provide a plastic product demolding and polishing device that achieves high polishing and grinding efficiency and can cool and clean in a timely manner.
[0005] The technical solution adopted by this application to solve its technical problem is: a plastic product demolding and polishing device, including a base, a worktable fixedly installed on the upper end of the base, a protective plate fixedly installed on the upper end of the worktable, a display controller fixedly installed on the upper end of the protective plate, a transport platform fixedly installed on the upper end of the worktable, a robotic arm fixedly installed on the side end of the transport platform, a polishing component installed on the front end of the transport platform, and a feed door connected to the front hinge of the protective plate.
[0006] Furthermore, the polishing assembly includes a drive motor, which is fixedly mounted on the side of the worktable. Auxiliary wheels are rotatably connected to both sides of the drive motor, and a polishing belt is wrapped around the outside of the auxiliary wheels. The drive motor is electrically connected to the display controller.
[0007] Furthermore, a rotating motor is fixedly installed on the side of the drive motor, and a polishing disc is rotatably connected to the front end of the rotating motor. The rotating motor is electrically connected to the display controller.
[0008] Furthermore, an electric gripper is fixedly installed at the front end of the robotic arm, and both the robotic arm and the electric gripper are electrically connected to the display controller.
[0009] Furthermore, a dust-collecting plate is fixedly installed at the lower end of the polishing disc. The dust-collecting plate is electrically connected to the display controller, and several dust-collecting holes are opened at the upper end of the dust-collecting plate.
[0010] Furthermore, a cooling fan is fixedly installed on the top of the protective plate, and the cooling fan is electrically connected to the display controller.
[0011] The beneficial effects of this utility model are: during the polishing process, the display controller activates the dust suction plate, which uses the dust suction holes to absorb the generated dust and debris in real time, keeping the working environment clean. During operation, the cooling fan runs continuously to reduce the temperature of components such as the drive motor and the rotating motor, preventing the equipment from overheating.

[0019] like Figure 1-2As shown, this application provides a plastic product demolding and polishing device, including a base 1, a worktable 5 fixedly installed on the upper end of the base 1, a protective plate 2 fixedly installed on the upper end of the worktable 5, a display controller 6 fixedly installed on the upper end of the protective plate 2, a transport table 8 fixedly installed on the upper end of the worktable 5, a robotic arm 7 fixedly installed on the side end of the transport table 8, a polishing component installed on the front end of the transport table 8, and a feed door 3 connected to the front end of the protective plate 2 via a hinge.
[0020] The base 1 has a workbench 5 fixedly installed on its upper end, a protective plate 2 fixedly installed on its upper end, a display controller 6 fixedly installed on its upper end, a transport table 8 fixedly installed on its upper end, a robotic arm 7 fixedly installed on the side of the transport table 8, a polishing assembly installed at the front end of the transport table 8, and a feed door 3 connected to the front hinge of the protective plate 2.
[0021] A rotating motor is fixedly installed on the side of the drive motor 10, and a polishing disc 12 is rotatably connected to the front end of the rotating motor. The rotating motor is electrically connected to the display controller 6.
[0022] An electric gripper 9 is fixedly installed at the front end of the robotic arm 7, and both the robotic arm 7 and the electric gripper 9 are electrically connected to the display controller 6.
[0023] A dust-collecting plate is fixedly installed at the lower end of the polishing disc 12. The dust-collecting plate is electrically connected to the display controller 6, and several dust-collecting holes 13 are opened at the upper end of the dust-collecting plate.
[0024] A cooling fan 4 is fixedly installed on the top of the protective plate 2, and the cooling fan 4 is electrically connected to the display controller 6.
[0025] Specifically, the staff first opens the feed gate 3, then places the demolded plastic product on the transport table 8, which is automatically transported to the processing area.

After placement, the drive motor 10 is started by the display controller 6. The drive motor 10 starts and drives the auxiliary wheels 14 on both sides to rotate. The rotation of the auxiliary wheels 14 drives the grinding belt 11 to run. The grinding belt 11 runs to perform preliminary grinding on the surface of the workpiece.
[0026] After the polishing is completed, the staff will start the rotating motor again through the display controller 6. The rotating motor will drive the polishing disc 12 to rotate, and perform fine polishing on the details or complex curved surfaces of the workpiece.
[0027] During the polishing process, the display controller 6 activates the dust suction plate, which uses the dust suction holes 13 to continuously absorb the generated dust and debris, keeping the working environment clean. During operation, the cooling fan 4 runs continuously to reduce the temperature of components such as the drive motor 10 and the rotating motor, preventing the equipment from overheating.
