Description

Technical Field

[0001] This utility model relates to the technical field of polishing devices, specifically a polishing device for producing automobile nameplates. Background Technology

[0002] Vehicle identification plates are an important part of vehicles, and usually contain information such as the vehicle's brand, model, engine displacement, country of manufacture, and manufacturer's name. Polishing equipment is required when manufacturing vehicle identification plates to ensure that the surface of the plates is smooth and clear, so as to provide high-quality products.

[0003] For example, Chinese patent CN218891658U discloses a polishing device for sign production, including a base, an I-shaped bracket fixedly connected to the base, a hydraulic cylinder fixedly connected to the inner wall of the I-shaped bracket, an elliptical polishing block fixedly connected to the bottom of the hydraulic cylinder, a sign placement component on the I-shaped bracket, a rotating handle on the sign placement component, and a fixing component on the sign placement component. The polishing distance between the elliptical polishing block and the sign can be adjusted by the hydraulic cylinder below the I-shaped bracket. The hydraulic cylinder is a swing-type hydraulic cylinder, so it can drive the elliptical polishing block to rotate during the polishing process, continuously polishing the sign through reciprocating motion. The sign placement component has a double-layered component for fixing the sign. Furthermore, the sign fixed on the sign placement component can be easily rotated and flipped over by manually rotating the rotating handle, thereby improving its polishing efficiency.

[0004] Although the aforementioned patent allows for easy rotation of the signboard within the signboard placement component by manually rotating the handle, thereby improving its polishing efficiency, the polishing device uses a hydraulic cylinder to drive an elliptical polishing block to polish the signboard. This makes it difficult to fully polish the upper surface of the signboard, thus reducing its practicality. Utility Model Content

[0041] The working principle of the above embodiments is as follows:

[0042] (1) The car logo plate to be polished can be placed on the upper surface of the support platform 1.

During polishing, the moving module 31 can be started through the control panel 5. The moving module 31 drives the rotating polishing wheel 384 to move back and forth and left and right to polish the car logo plate. The polishing quality can be improved by the pressure value of the polishing wheel 384 pressing down on the car logo plate.

[0043] (2) During polishing, the liquid pump 42 can be started. The liquid pump 42 transports the water inside the water tank 41 to the spray pipe 44 through the pipe. The spray pipe 44 sprays water, which can cool down the polishing wheel 384, improve the polishing stability of the polishing wheel 384, and increase the service life of the polishing wheel 384.
