In addition, the technical solutions of each example can be combined with each other, but it must be based on the realization of the ordinary skill in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection required by the utility model.

[0062] Please refer to Figures 1-7 A spraying device for metal sign surface treatment, which mainly comprises a spraying table 1, a top table 2, a side clamping positioning assembly 7, a clamping driving mechanism 8, a front and rear driving mechanism 6, a telescopic cylinder 5, a spraying assembly 4 and a liquid supply mechanism 3.

[0063] The structure of the spraying table 1 and the side clamping positioning assembly 7:

[0064] The spraying table 1 is the bottom platform of the whole spraying device, and the top left and right sides are provided with the side clamping positioning assembly 7. Each side clamping positioning assembly 7 is composed of a side mounting frame 71, a side clamping block 73 and a distance adjusting mechanism 72. The side clamping block is responsible for clamping the metal sign and the hollow template stacked above, and ensures the position stability in the spraying process. The distance adjusting mechanism 72 drives the first driving lead screw 722 at the front and rear ends to rotate through the first double-shaft reduction motor 721, and then drives the first lead screw sleeve 723 at the front and rear to move synchronously relative and opposite, so that the side clamping blocks 73 at the front and rear ends can move relative or opposite, to adjust the distance between the two side clamping blocks 73 on the same side, and then adapt to the spraying operation of metal signs of different sizes.

[0065] The structure of the clamping driving mechanism:

[0066] The clamping driving mechanism 8 is installed in the transverse installation groove 11 inside the spraying table. The mechanism is driven by the second double-shaft reduction motor 81 and the second driving lead screw 82, which drives the two second lead screw sleeves 723 to move synchronously towards or away from each other, and then drives the two side clamping positioning assemblies 7 to move synchronously towards or away from each other, so as to ensure that the side clamping blocks can be effectively adjusted and clamped when the signs of different sizes are placed.

[0067] Structure of the top table and the spraying assembly:

[0068] The top table 2 is installed directly above the spraying table and is used to support and install the core part of the spraying system. The front and rear driving mechanism 6 is installed inside the top table. The mechanism drives the positioning lead screw 62 through the reduction motor 61, drives the threaded sleeve 63 to move forward and backward on the lead screw, and then drives the telescopic cylinder 5 and the spraying assembly 4 to move forward and backward, realizing complete spraying operation.

[0069] The spraying assembly includes a liquid collecting box 41 and a plurality of flat liquid spraying nozzles 42. The nozzles are evenly distributed on the bottom of the liquid collecting box and are arranged in a straight line, which is used to spray paint on the surface of the metal sign.

[0070] Structure of the liquid supply mechanism:

[0071] The liquid supply mechanism 3 is mainly composed of a paint storage tank 31, a liquid pumping pump 32 and a liquid guide hose 33. The paint is pumped from the paint storage tank by the liquid pumping pump and is transmitted to the spraying assembly 4 through the liquid guide hose, ensuring that the nozzles can continuously spray paint.

[0072] Configuration of the spraying template and the supporting table:

[0073] A supporting table 9 is arranged at the top center of the spraying table 1, which is used to place the metal signs to be sprayed and the hollow spraying template. The spraying template and the metal sign are stacked on the supporting table and clamped by the side clamping positioning assemblies on both sides, ensuring the stability of the sign during the spraying process.

[0074] Second embodiment

[0075] In this embodiment, the spraying device is mainly used for processing metal signs of different sizes. The working process of the device is as follows:

[0076] Fixing of the sign:

[0077] Place the metal sign to be sprayed on the supporting table 9 at the top of the spraying table, adjust the distance between the side clamping blocks 73 to ensure that the sign is clamped firmly. Adjust the movement of the side clamping blocks through the distance adjusting mechanism 72 to realize the fixation of signs of different specifications.

[0078] Spraying operation:

[0079] The spraying device is started, the liquid pump 32 starts to draw paint from the paint storage tank 31, the paint is transported to the spraying assembly 4 through the liquid guide hose 33. The multiple liquid spraying nozzles 42 of the spraying assembly spray paint uniformly downward, covering the surface of the sign.

[0080] Adjust the spraying position:

[0081] According to the size and shape of the sign, the front and rear movement of the spraying assembly is controlled by the front and rear driving mechanism 6 to ensure that the paint can be uniformly sprayed to every corner of the sign. The telescopic air cylinder 5 further adjusts the spraying distance of the spraying assembly to achieve the best coating effect.

[0082] Complete spraying:

[0083] After spraying is completed, the equipment is stopped, the side clamping block 73 is loosened, and the metal sign that has completed spraying is taken out.
