Description

Technical Field

[0001] This utility model belongs to the field of metal sign processing technology, and in particular relates to a metal sign spraying equipment. Background Technology

[0002] The purpose of advertising is to realize economic and social value through information dissemination. Therefore, advertising products helps increase their exposure, enabling more people to understand the specific details of the products and promoting sales. During the advertising process, relevant advertising information is printed on metal signs for easy installation and carrying. The surface of the metal signs is also coated to improve their applicability and lifespan. Generally, workers operate coating equipment to process the metal signs.

[0003] A search revealed a spraying device for sign manufacturing in patent document CN219745217U, but it still has the following drawbacks in actual use:

[0004] 1. The spraying equipment for manufacturing signs disclosed in the patent document with patent publication number CN219745217U has a fixed sleeve connected to the top of the spraying box. The fixed sleeve has a sliding rod inside. The lower end of the sliding rod is connected to the lower surface of the mounting plate, which has a hook 2 connected to it. The upper end of the tension spring connected to the upper surface of the mounting plate is connected to the top of the spraying box. The bottom of the spraying box has a hook 1 connected to it. The upper through hole of the sign is hung on the hook 2. When the sign is pulled, the hook 2 moves downward and hangs the lower through hole of the sign on the hook 1, thus limiting the position of the sign. However, the sign does not have a through hole. It is necessary to drill a hole in the sign to limit the hanging of the sign, which will cause unnecessary damage to the sign.

[0005] 2. The spraying equipment for manufacturing signs disclosed in the patent document with patent publication number CN219745217U has a vertically rotatably connected threaded rod inside the spraying box. The side wall of the threaded block set around the threaded rod has a connected fan-shaped nozzle. The output end of the servo motor is connected to the end of the threaded rod. When the servo motor is powered on, the threaded rod rotates, and the height of the fan-shaped nozzle is adjusted to spray the hanging signs. However, the undried spray liquid on the signs will flow downwards due to its own gravity, which will cause the spray liquid on the surface of the signs to be uneven and reduce the spraying quality.

[0006] To address these issues, we provide a metal sign spraying equipment. Utility Model Content

[0007] The purpose of this utility model is to provide a metal sign spraying device. By setting up a clamping component, it is easy to clamp metal signs of different sizes, which increases the applicability. It also eliminates the need to drill holes in the metal signs, reducing damage. Furthermore, by setting up a spraying component, it is convenient to dry the spray liquid on the surface of the metal signs, reducing the flow of undried spray liquid and ensuring the smoothness of the surface after spraying. This solves the technical problems raised in the background art of the sign manufacturing spraying device disclosed in the patent document with patent publication number CN219745217U.

When the motor 102 is powered on, the driven roller 101a and the driving roller 101b rotate, and the conveyor belt 101 works to transport the metal sign to the spraying position.

[0029] Specifically, a driven roller 101a and a driving roller 101b are provided above the base plate 1. Both the driven roller 101a and the driving roller 101b have vertically rotatably connected support legs 101c on their periphery. The support legs 101c are connected to the base plate 1.

A motor 102 is provided below the driving roller 101b and is connected to the side wall of the support leg 101c. The output end of the motor 102 has a parallel-connected rotating shaft 102a. The end of the rotating shaft 102a passes through the support leg 101c. The end of the rotating shaft 102a is connected to a driving wheel 103b. The end of the driving roller 101b is connected to a driven wheel 103a. The driven wheel 103a and the driving wheel 103b are together fitted with a transmission belt 103.

[0030] Furthermore, the four legs are arranged in a rectangular array;

[0031] The operation process of this embodiment is as follows: the motor 102 is powered on, the rotating shaft 102a rotates, the drive roller 101b rotates, the conveyor belt 101 works, the metal identification plate is placed on the conveyor belt 101, and the metal identification plate is transported to the spraying position.

[0032] Example 2

[0033] Please see Figure 1Based on the first specific embodiment, a clamping assembly 2 is provided. The clamping assembly 2 includes a mounting frame 201, a guide roller 201a and a cylinder 203. When the cylinder 203 is opened, the piston rod on the cylinder 203 extends or retracts, adjusting the distance between the two mounting frames 201, so that the guide roller 201a limits both sides of the metal nameplate and facilitates the transportation of the metal nameplate. There is no need to drill holes in the metal nameplate, which prevents the metal nameplate from being damaged.

[0034] Specifically, cylinder 203 is arranged parallel above base plate 1. The lower part of cylinder 203 is connected to base plate 1 by a bracket. The piston rod end of cylinder 203 is connected to mounting bracket 201. Mounting bracket 201 is located above conveyor belt 101. Inside mounting bracket 201, there is a vertically rotatably connected guide roller 201a. Above base plate 1, there is a parallel arranged connecting cylinder 202. The lower part of connecting cylinder 202 is vertically connected to base plate 1 by a bracket. Inside connecting cylinder 202, there is a sleeved movable shaft 202a. The end of movable shaft 202a is connected to the side wall of mounting bracket 201.

[0035] Furthermore, the two mounting brackets 201 are symmetrically arranged, the mounting brackets 201 are U-shaped, the guide rollers 201a are equidistantly distributed, the four connecting cylinders 202 are distributed in a rectangular array, and the two cylinders 203 are symmetrically arranged.

[0036] The operation process of this embodiment is as follows: After the metal nameplate is placed on the conveyor belt 101, the cylinder 203 is opened. When the piston rod at the telescopic end of the cylinder 203 extends, the two mounting brackets 201 move towards each other, and the guide roller 201a moves towards the metal nameplate. When the piston rod at the telescopic end of the cylinder 203 retracts, the two mounting brackets 201 move away from each other, and the guide roller 201a moves away from the metal nameplate until both sides of the metal nameplate are in contact with the guide roller 201a, thus limiting the trajectory of the metal nameplate during transportation and better spraying the metal nameplate.
