[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1 , a surface polishing device for producing metal highway signs, comprising a base 1, a placement seat 2 is fixedly mounted on the base 1, a polishing mechanism is mounted on the base 1, and a cavity is opened inside the placement seat 2;

[0024] The upper surface of the placement seat 2 is provided with a plurality of suction holes all connected to the cavity, and the plurality of suction holes are arranged in a row of three at equal intervals on the placement seat 2. A connecting pipe is fixedly installed on the side of the placement seat 2, and the connecting pipe is connected to the cavity;

[0025] like Figure 1 , Figure 2As shown, a suction cylinder 3 is fixedly installed on the base 1, one end of the suction cylinder 3 is sealed and connected with the connecting pipe, a movable plate 4 is slidably installed in the suction cylinder 3, and the movable plate 4 is sealed and slidably connected with the inner wall of the suction cylinder 3, and a moving rod 5 is slidably installed in the suction cylinder 3 through an elastic component, and a pull rod 6 is fixedly installed on the end of the moving rod 5 away from the connecting pipe, and the other end of the moving rod 5 is fixedly connected with the moving plate 4, and a locking component for locking the pull rod 6 is provided on the suction cylinder 3; the elastic component includes a mounting plate 7 fixedly installed at one end of the suction cylinder 3 and a telescopic spring 8 sleeved on the moving rod 5, a moving hole is opened on the mounting plate 7, and the moving rod 5 is slidably inserted in the moving hole, and the two ends of the telescopic spring 8 are fixedly connected to the mounting plate 7 and the moving plate 4 respectively; the locking component includes two support rods 9 symmetrically rotatably installed on the pull rod 6 and two positioning blocks 10 symmetrically fixedly installed on the mounting plate 7, and both positioning blocks 10 are provided with positioning grooves;

[0026] When processing the sign, place the sign on the placement seat 2, the sign will block the suction hole on the placement seat 2, and then pull the pull rod 6 to drive the moving rod 5 to move away from the connecting pipe, thereby driving the moving plate 4 to move, and the telescopic spring 8 is compressed. During the movement, the moving plate 4 will suck the gas in the cavity into the suction tube 3, so that the gas in the cavity becomes less and is in a negative pressure state. Under the action of atmospheric pressure, the sign will be stably adsorbed on the placement seat 2. When the edge of the sign is polished, this method of fixation will not affect the polishing of the edge of the sign. It is easy to operate and effectively improves the polishing effect.

[0027] A sealing gasket 11 is fixedly installed on the placement seat 2. The sealing gasket 11 is provided with multiple through holes respectively connected to the suction holes. A plurality of sealing components are provided in the cavity. The sealing components are used to seal each column of suction holes. The sealing gasket 11 can reduce the gap between the sign and the placement seat 2, thereby facilitating the sign to be adsorbed on the placement seat 2.

[0028] like Figure 3 , Figure 4As shown, the blocking assembly includes two L-shaped blocking plates 12 corresponding to the suction holes, two U-shaped blocks 13 respectively slidably mounted on the two blocking plates 12, two L-shaped rods 14 respectively fixedly mounted on one end of the two blocking plates 12 close to the side wall of the cavity, two spring rods 15 respectively fixedly mounted on the two L-shaped rods 14 and parallel to the L-shaped rods 14, and a limiting component for limiting the movement of the L-shaped rods 14; the top wall of the blocking plate 12 is sealed and slidably connected to the upper wall of the inner cavity, and the two U-shaped blocks 13 are fixedly mounted The spring rod 15 is mounted on the upper wall of the cavity, and one end of the spring rod 15 away from the L-shaped rod 14 is fixedly connected to the side wall of the cavity. The side wall of the placement seat 2 is provided with a plurality of rectangular holes all connected to the cavity, and the L-shaped rod 14 is slidably inserted in the rectangular holes; an insertion hole is provided on the end of the L-shaped rod 14 extending out of the rectangular hole, and the limiting component includes a pin 16 detachably inserted in the insertion hole and a limit block 17 fixedly installed on the side of the base 1 and arranged corresponding to the L-shaped rod 14, and a limit hole for accommodating the pin 16 is provided on the limit block 17;

[0029] When polishing signs of different sizes, the opening of the suction holes on the placement seat 2 can be controlled according to the length of the sign. Under the action of the elastic force of the spring rod 15, one ends of the two blocking plates 12 approach each other until they are against each other. A plurality of suction holes in a row can be blocked by the two blocking plates 12. When the suction holes need to be opened, the L-shaped rod 14 is pulled to drive the blocking plate 12 to move toward the spring rod 15. The spring rod 15 is compressed, and the L-shaped rod 14 drives the latch 16 to move toward the limit block 17 during the movement. Then, one end of the latch 16 is inserted into the limit hole, thereby limiting the movement of the L-shaped rod 14. At the same time, the two blocking plates 12 are just separated from the suction holes, thereby opening the suction holes under the sign.

[0030] In the utility model, when processing the sign, the sign is placed on the placement seat 2, and then the pull rod 6 is pulled to drive the movable plate 4 to move through the movable rod 5. The movable plate 4 will suck the gas in the cavity into the suction tube 3 during the movement, so that the gas in the cavity becomes less and is in a negative pressure state. Under the action of atmospheric pressure, the sign will be stably adsorbed on the placement seat 2. When the edge of the sign is polished, this method of fixation will not affect the polishing of the edge of the sign. The operation is convenient and the polishing effect is effectively improved.

[0031] In general, in response to the technical problem: when processing some thinner signs, the presence of the splint will affect the polishing of the edge of the sign, the operation is very inconvenient, and the polishing effect is poor; a technical solution is adopted: through the cooperation of the suction tube 3, the movable plate 4, the movable rod 5, the pull rod 6 and the locking assembly, the sign is adsorbed on the placement seat 2; because the implementation process of the technical solution is: when processing the sign, the sign is placed on the placement seat 2, and then the pull rod 6 is pulled to drive the movable plate 4 to move through the movable rod 5. During the movement of the movable plate 4, the gas in the cavity will be sucked into the suction tube 3, so that the gas in the cavity becomes less and is in a negative pressure state. Under the action of atmospheric pressure, the sign will be stably adsorbed on the placement seat 2; so the technical problem will inevitably be solved, and the technical effect achieved is: when the edge of the sign is polished, it will not affect the polishing of the edge of the sign, the operation is convenient, and the polishing effect is effectively improved.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
