[0029] This embodiment discloses a plate camouflage dyeing device.

[0030] See also Figure 1-5 The plate camouflage dyeing equipment includes a processing table 1 and a storage table 2 arranged on the top of the processing table 1. The plate to be dyed is placed on the storage table 2. A positioning mechanism and a limiting mechanism can be set on the top of the storage table 2 to ensure that the plate can be accurately placed on the storage table 2.

[0031] A pair of notches 11 are provided on both sides of the top of the processing table 1 . The notches 11 are located below the outer edge of the storage table 2 . In this way, the notches 11 can form an open accommodating cavity extending along the length direction of the processing table 1 . The cam 31 is provided with a plurality of support rods 31 on the upper side of the support rod 31, and the support rods 31 are provided with a plurality of support rods 31 on the upper side of the support rod 31. The support rods 31 are L-shaped, and the vertical ends of the support rods 31 are connected to the bottom of the movable plate 3. The horizontal ends of the support rods 31 are passed through the notch 11 and connected to the linear slide 12, and the bottom of the horizontal ends of the support rods 31 are pressed on the top of the slide seat of the linear slide 12. A pair of pressure strips 20 are symmetrically provided at the bottom of the storage platform 2. The pressure strips 20 are located in the notch 11, and the bottom of the pressure strips 20 is in contact with the top of the horizontal ends of the support rods 31. In this way, by adjusting the thickness of the pressure strips 20, it can be ensured that the horizontal ends of the support rods 31 can be clamped between the slide seat of the linear slide 12 and the pressure strips 20, thereby improving the stability of the linear slide 12 driving the support rods 31 and ensuring that the movable plate 3 can reliably reciprocate on the top of the storage platform 2.

[0032] A plurality of nozzles 32 are provided at the bottom of the movable plate 3, and the plurality of nozzles 32 are arranged at intervals along the length direction of the movable plate 3, and the nozzles 32 can spray dye toward the top of the plate to be dyed. A heating unit 4 and a purge unit 5 are also provided on the movable plate 3, and the nozzles 32 are located between the heating unit 4 and the purge unit 5. The heating unit 4 includes a first mounting plate 41 and a heating wire 42, and the purge unit 5 includes a second mounting plate 51 and a plurality of air blowing pipes 52, and the plurality of air blowing pipes 52 are arranged at intervals along the length direction of the second mounting plate 51.

One end of the second mounting plate 51 is arranged in the second accommodating groove 34, and the other end of the second mounting plate 51 extends to the bottom of the movable plate 3. A plurality of blowing pipes 52 are arranged at the other end of the second mounting plate 51 and blow air toward the top of the plate.

[0033] A slide groove 511 and a brush strip 54 are provided on the side of the second mounting plate 51 away from the nozzle 32. A slider 512 is adapted to be provided in the slide groove 511. The slider 512 is connected to the brush strip 54. The slide groove 511 is a dovetail groove. The outer wall of the slider 512 fits with the inner wall of the slide groove 511. In this way, the slider 512 can slide in the slide groove 511 but will not fall from the slide groove 511, so that the brush strip 54 can reliably slide back and forth along the length direction of the slide groove 511. Bristles 540 are provided at the bottom of the brush strip 54. The bristles 540 fit with the top of the plate. A rack 55 is provided at the top of the brush strip 54. The rack 55 extends along the length direction of the brush strip 54. A gear 57 driven by a motor 56 is provided on the outer wall of the second mounting plate 51. The gear 57 and the rack 55 are in a mutually meshing state. When the motor 56 drives the gear 57 to rotate back and forth, the rack 55 meshing with the gear 57 will produce a reciprocating motion along the length direction of the slide 511, and the rack 55 is fixed to the top of the brush strip 54. When the rack 55 moves, the brush strip 54 can also produce a synchronous movement, thereby reliably driving the bristles 540 to brush the top of the plate, effectively removing the debris on the top of the plate. Further, the air blowing pipe 52 on the rear side of the bristles 540 can blow air toward the plate and the bristles 540, thereby reliably blowing the debris brushed out by the bristles 540 away from the plate, so that the plate can be kept clean, which is convenient for the spray head 32 to spray paint.

[0034] The second mounting plate 51 is arranged at the front side of the moving direction of the nozzle 32 during painting, and the first mounting plate 41 is arranged at the rear side of the moving direction of the nozzle 32 during painting, that is, when the linear slide 12 drives the movable plate 3 to move forward, the second mounting plate 51 will move at the front, and the first mounting plate 41 will move at the rear, so that after the bristles 540 and the air blow pipe 52 have blown and prepared the top of the plate, the nozzle 32 on the rear side of the air blow pipe 52 can then spray the dye, and during the spraying process of the nozzle 32, the heating wire 42 located on the rear side of the nozzle 32 can follow closely and dry the dye, so that the blowing, painting and drying operations are performed in sequence, so that the three processes can be seamlessly connected, thereby improving the overall processing efficiency and maximizing the quality of the finished product.

[0035] Two through holes 37 are provided on the top of the movable plate 3, one through hole 37 is communicated with the first receiving groove 33, and the other through hole 37 is communicated with the second receiving groove 34. A hydraulic cylinder 35 and a cross bar 36 are also provided on the top of the movable plate 3, one end of the cross bar 36 is provided with a first connecting rod 43, and the other end of the cross bar 36 is provided with a second connecting rod 53, one end of the first connecting rod 43 is connected to one end of the cross bar 36, and the other end of the first connecting rod 43 penetrates into the first receiving groove 33 through one through hole 37 and is connected to the first mounting plate 41, one end of the second connecting rod 53 is connected to the other end of the cross bar 36, and the other end of the second connecting rod 53 penetrates into the second receiving groove 34 through another through hole and is connected to the second mounting plate 51. The push rod of the hydraulic cylinder 35 is connected to the bottom center of the cross bar 36. When the push rod of the hydraulic rod is extended upward, it can push the cross bar 36 to move upward, thereby realizing the lifting effect of the first connecting rod 43, the first mounting plate 41, the second connecting rod 53 and the second mounting plate 51. When the push rod of the hydraulic rod is retracted downward, the first mounting plate 41 and the second mounting plate 51 can also be lowered accordingly. In this way, the synchronous adjustment of the height of the heating wire 42, the air pipe 52 and the bristles 540 is realized.

[0036] Further, a threaded hole 360 ​​is provided on the crossbar 36, and the threaded hole 360 ​​penetrates the crossbar 36, and the first connecting rod 43 is a threaded rod, and the first connecting rod 43 is adapted to be screwed in the threaded hole 360, and a hand wheel 430 is provided on the top of the first connecting rod 43, and a bearing 410 is provided on the top of the first mounting plate 41, and the outer ring of the bearing 410 is connected to the first mounting plate 41, and the first connecting rod 43 is inserted into the inner ring of the bearing 410 and has an interference fit with the inner ring of the bearing 410. After the hand wheel 430 is turned, the first connecting rod 43 will rotate, and the first connecting rod 43 and the threaded hole 360 ​​are in a threaded connection relationship, so that the height of the first connecting rod 43 can be adjusted, and the first connecting rod 43 and the first mounting plate 41 are connected through the bearing 410, which enables the rotation and lifting of the first connecting rod 43 to achieve the linear lifting and lowering of the first mounting plate 41, thereby achieving the fine adjustment of the height of the heating wire 42. By precisely adjusting the height of the heating wire 42 , it is ensured that the heating wire 42 can reliably dry the dye on the plate while preventing the heating wire 42 from being too close to the plate to burn the dye, thereby effectively improving the quality of the finished product.
