[0016] To make the technical problems solved by the invention, the technical solutions and the beneficial effects clearer, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-10 As shown, the present invention provides a coating equipment for sheet metal, including a conveying mechanism 1, a spray frame 2, and a spray coating mechanism 3. The conveying mechanism 1 is used to convey the sheet metal, and the spray frame 2 is mounted on the conveying mechanism 1. The spray coating mechanism 3 is mounted on the spray frame 2. The spray coating mechanism 3 includes a left spraying seat 301, a right spraying seat 302, and an adjusting seat 303. A liquid tank 4 is formed on the left spraying seat 301 and / or the right spraying seat 302. The adjusting seat 303 includes a clamping plate 3031 and adjusting plates 3032 vertically fixed at both ends of the clamping plate 3031. The adjusting plate 3032 contains... A receiving groove 5 is provided, and a movable plate 6 that can move between two adjusting plates 3032 is provided in the receiving groove 5. The adjusting seat 303 is fixedly clamped between the left spraying seat 301 and the right spraying seat 302. A left mounting groove 7 is provided on the inner side of the left spraying seat 301, and the left part of the adjusting seat 303 is located in the left mounting groove 7. A right mounting groove 8 is provided on the inner side of the right spraying seat 302, and the right part of the adjusting seat 303 is located in the right mounting groove 8. A narrow gap 9 is left between the left spraying seat 301 and the right spraying seat 302. When the movable plate 6 extends out of the receiving groove 5, it blocks part of the narrow gap 9.

[0018] The sheet material is conveyed to the bottom of the spray coating mechanism 3 via the conveying mechanism 1. Adhesive flows from the liquid tank 4 to the narrow slit 9, forming a curtain at the narrow slit 9 and spraying it onto the sheet material. An adjusting seat 303 is provided in the spray coating mechanism 3, and a movable plate 6 is placed on the adjusting seat 303. The movable plate 6 can move between the left spray seat 301 and the right spray seat 302. The length by which the movable plate 6 moves out from the adjusting plate 3032 determines the degree of blockage in the narrow slit 9. By adjusting the position of the movable plate 6, the length of the narrow slit 9 can be adjusted to accommodate sheet materials of different sizes, thus broadening the application range.

[0019] The adjusting seat 303 can be fixed between the left spraying seat 301 and the right spraying seat 302 by screws, etc. The height of the adjusting seat 303 is greater than the height of the movable plate 6. On the one hand, the adjusting seat 303 can accommodate the movable plate 6. On the other hand, the adjusting seat 303 can also accommodate the driving component that drives the movable plate 6. In order to match the shape of the adjusting seat 303 and the movable plate 6, a left mounting groove 7 and a right mounting groove 8 are respectively opened on the left spraying seat 301 and the right spraying seat 302. The left spraying seat 301 and the right spraying seat 302 do not contact each other and leave a narrow gap 9 to facilitate the glue to flow out from the narrow gap 9.

[0020] Furthermore, a liquid inlet 10 is provided on the liquid tank 4, through which the adhesive flows into the liquid tank 4, and the liquid tank 4 is connected to the narrow slit 9. The adhesive supply mechanism is connected to the liquid inlet 10 through a pipe, and the adhesive supply mechanism provides a continuous supply of adhesive liquid to the liquid tank 4. The narrow slit 9 is directly opposite the board, and the adhesive flows out under the action of gravity.

[0021] Furthermore, the spray coating mechanism 3 includes a telescopic cylinder 11, which is fixed to the spray coating mechanism 3. The telescopic end of the telescopic cylinder 11 extends into the adjusting seat 303 and fixes the movable plate 6. The telescopic cylinder 11 acts as a driving component to control the movement of the movable plate 6.

[0022] Furthermore, the height of the movable plate 6 is equal to the height of the narrow slit 9, and an elastic sealing strip 12 is provided around the perimeter of the movable plate 6, which abuts against the movable plate 6 and the left spraying seat 301 and the right spraying seat 302.

[0023] Under the influence of gravity, the adhesive flows downward out of the narrow slit 9 and does not flow upward. Therefore, there is no need to worry about the adhesive clogging the narrow slit 9 above the liquid tank 4. The movable plate 6 can completely block both sides of the narrow slit 9 and limit the length of the narrow slit 9. The adhesive can only flow out from the unblocked narrow slit 9. The length of the narrow slit 9 is adapted to the coating width of the board. By adjusting the position of the movable plate 6, the outflow length of the adhesive can be adjusted to adapt to different board sizes.

[0024] Furthermore, a guide groove 13 is provided on the inner side of the clamping plate 3031, and one side of the movable plate 6 is movably disposed within the guide groove 13. The one side of the movable plate 6 moves along the guide groove 13, which further enhances the stability of the movement of the movable plate 6, limits the direction of movement of the movable plate 6, and prevents the movable plate 6 from swaying up and down during movement.

[0025] Furthermore, the spray frame 2 is also equipped with an upper pressure roller 14 and a lower pressure roller 15. The upper pressure roller 14 is located directly above the lower pressure roller 15. The height of the upper pressure roller 14 is adjustable. The upper pressure roller 14 and the lower pressure roller 15 are located at the rear end of the spray coating mechanism 3.

[0026] After coating, the sheet passes between the upper pressure roller 14 and the lower pressure roller 15. The height of the upper pressure roller 14 is adjusted by the cylinder component 21 to accommodate sheets of different thicknesses. The upper pressure roller 14 and the lower pressure roller 15 rotate, driving the sheet to the rear end and flattening the coating layer on the surface of the sheet, making the coating more uniform.

[0027] Furthermore, the conveying mechanism 1 includes a front conveyor belt 101 and a rear conveyor belt 102, and a lower pressure roller 15 is disposed between the front conveyor belt 101 and the rear conveyor belt 102. The height of the lower pressure roller 15 is equal to the height of the front conveyor belt 101 and the rear conveyor belt 102.

[0028] Furthermore, a protective cover 16 is fixed on the spray frame 2. The protective cover 16 covers the bottom of the spray coating mechanism 3 and does not contact the conveying mechanism 1. The protective cover 16 protects the spray coating mechanism 3, preventing dust and other contaminants from entering below the spray coating mechanism 3 and preventing contamination of the adhesive.

[0029] Furthermore, a vertical support rod 17 is fixed to the bottom of the movable plate 6, and a vertical and rotatable guide roller 18 is provided on the support rod 17. The guide roller 18 is used to guide the plate material into the spray coating mechanism 3.

[0030] When the movable plate 6 moves, its bottom support rod 17 moves accordingly, and the plate passes between the two guide rollers 18. The two guide rollers 18 constrain the plate to the middle position of the conveying mechanism 1, thus achieving a centering effect and ensuring that the narrow slit 9 is directly opposite the plate, guaranteeing the accuracy of the coating. The guide rollers 18 are close to the conveying mechanism 1 but do not contact it, ensuring that the guide rollers 18 can guide the plate. The guide rollers 18 do not require a drive. During the conveying process of the conveying mechanism 1, the guide rollers 18 rotate with the plate, and the guide rollers 18 do not affect the normal conveying of the plate. At the same time, under the further conveying of the upper pressure roller 14 and the lower pressure roller 15, the conveying direction of the plate will not change.

[0031] Furthermore, an extension rod 19 is fixed on the support rod 17, and an arc-shaped guide plate 20 is fixed on the extension rod 19. The arc-shaped guide plate 20 guides the plate between the two guide rollers 18.

[0032] The distance between the two arc-shaped guide plates 20 gradually decreases. Even if the material shifts during the conveying process, it will smoothly enter the space between the two guide rollers 18 under the guidance of the arc-shaped guide plates 20, achieving a centered position and ensuring accurate coating.

[0033] This invention incorporates an adjustment seat 303 within the spray coating mechanism 3. Two movable plates 6 are mounted on the adjustment seat 303 to block both sides of the narrow slit 9, adjusting its length to accommodate coating of different sized panels. Rotatable guide rollers 18 at the bottom of the movable plates 6 center the panel, ensuring it faces directly under the narrow slit 9 and guaranteeing coating accuracy. An arc-shaped guide plate 20 at the bottom of the movable plates 6 corrects the panel's orientation, accurately guiding it between the two guide rollers 18. This invention provides an adjustable coating area, adaptable to coating panels of different sizes.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
