Description

Technical Field

[0001] The utility model relates to the technical field of sign polishing, in particular to a sign polishing device. Background Art

[0002] Advertising signs are large signs or plaques used to display advertising information. They are usually placed in public areas such as buildings, roads, and commercial places to attract people's attention and convey specific advertising information. During the production process of advertising signs, they need to be polished to ensure the flatness and smoothness of the surface and increase the quality of the advertising signs.

[0003] Patent CN220217758U proposes an advertising sign grinding and polishing device. When grinding and polishing the advertising sign, the advertising sign is directly placed on the inner side of the U-shaped frame, and then fixed by a fixing mechanism, and the side of the advertising sign is made to contact with the grinding roller. At this time, the grinding roller is driven by the second motor, and the grinding roller is driven to move by the electric push rod, so that the side of the advertising sign can be ground and polished. The rotating rod can be driven to rotate by the coordinated use of the adjusting mechanism and the driven gear, thereby driving the advertising sign fixed on the placement plate to rotate, so that the contact position of the two adjacent surfaces of the advertising sign is in contact with the grinding roller, thereby facilitating the grinding and polishing of the contact position of the two adjacent surfaces of the advertising sign, so that more positions of the advertising sign can be polished, further improving the practicality of the device.

[0004] The shortcomings of the above scheme are: since the common metal signs on the market are square, round and triangular, and the scheme technology is more convenient for polishing regular signs, but it is more difficult to polish the edges of some triangular and round signs, and it is necessary to manually adjust the direction of the sign, which affects the polishing efficiency.
