A first fixed plate 191 is fixedly installed on the side of the first connecting plate 19 close to the rotating disk 18. A sliding rod 192 is slidably installed in the middle of the first fixed plate 191, and a connecting rod 193 is fixedly installed on the top of the sliding rod 192.

A nozzle 196 is arranged on the side of the second fixing plate 195 away from the second connecting plate 194. When the sheet metal is to be sprayed with paint, the rotating rod 12 is driven to rotate, and the disc 13 is driven to rotate, thereby driving the connecting block 14 and the turntable 18 to rotate. The rotation of the turntable 18 drives the connecting rod 193 to rise. When the turntable 18 rotates to a certain angle, it drives the connecting rod 193 to move downward, so that the sliding rod 192 is moved up in the first fixing plate 191. The dovetail block 17 is driven to descend in the dovetail groove 15 by rotating the first screw 16, thereby driving the turntable 18 to descend, so that the eccentric distance of rotation of the turntable 18 becomes larger, thereby increasing the distance of the up and down reciprocating motion of the sliding rod 192, thereby increasing the range of spraying of the nozzle 196. When the spraying range of the nozzle 196 is to be reduced, the reverse operation is performed.

[0023] A symmetrically distributed third fixed plate 2 is fixedly installed on both sides of the lower surface of the inner wall of the base plate 1 away from the fixed block 11, a second screw 21 is rotatably installed in the middle of the two third fixed plates 2, a slider 22 is threadedly sleeved on the middle of the second screw 21, a placing table 23 is fixedly installed on the outside of the slider 22, and symmetrically distributed clamping plates 24 are fixedly installed on both sides of the top of the placing table 23 close to the third fixed plate 2.

[0024] By adopting the above technical solution, the sheet metal is fixedly clamped in the clamping plate 24, and the second screw 21 is driven to rotate, thereby driving the placement table 23 to move forward, so that the sheet metal can be painted.

[0025] The two sides of the bottom end of the placement platform 23 away from the clamping plate 24 are fixedly installed with symmetrically distributed sliding plates 3, and the lower surface of the inner wall of the bottom plate 1 is provided with a second sliding groove 31.

[0026] By adopting the above technical solution and providing the slide plate 3 and the second slide groove 31, the placement table 23 can move more stably, thereby ensuring that the sheet metal can be more evenly painted, thereby improving the quality of the painting.

[0027] The slide plate 3 is movably engaged in the second slide groove 31 .

[0028] By adopting the above technical solution, the slide plate 3 is movably engaged in the second slide groove 31 , so that the slide plate 3 can move in the second slide groove 31 , thereby driving the placement table 23 to move.

[0029] A paint spray pipe 4 is fixedly installed in the middle of the second fixed plate 195, and a nozzle 196 is fixedly installed on the side of the paint spray pipe 4 away from the second fixed plate 195. Storage boxes 41 are fixedly installed on the bottom of both sides of the base plate 1 away from the fixed block 11. The storage box 41 and the paint spray pipe 4 are connected by a hose 42. A third slide groove 43 is opened on both sides of the base plate 1 close to the fixed block 11, and the hose 42 runs through the third slide groove 43.

[0030] By adopting the above technical solution, by arranging the paint spraying pipe 4, the storage box 41, the hose 42 and the third slide chute 43, the spray head 196 can spray paint, thereby completing the painting of the sheet metal.

[0031] The first motor 5 is coaxially fixedly installed on one end of the two rotating rods 12 away from the fixed block 11, and the second motor 51 is fixedly installed on one side of the third fixed plate 2 away from the placement table 23. The second motor 51 and the second screw rod 21 are coaxially fixedly installed.

[0032] By adopting the above technical solution, by setting the first motor 5, the rotating rod 12 can be rotated, thereby realizing the up and down reciprocating motion of the sliding rod 192, so that the paint sprayed by the nozzle 196 can be evenly sprayed onto the sheet metal, and by setting the second motor 51, the second screw 21 can be rotated, so that the sheet metal can be painted during the movement.

[0033] A rotating block 6 is fixedly mounted on the top of the first screw rod 16 , and the rotating block 6 is rotatably mounted on the top of the connecting block 14 .

[0034] By adopting the above technical solution and providing the rotating block 6 , the first screw rod 16 can be better rotated and the first screw rod 16 can also be supported.

[0035] Working principle: First, the sheet metal is fixed in the card plate 24, and the second screw 21 is driven to rotate, thereby driving the placement table 23 to move forward, so that the sheet metal can be painted;

[0036] Subsequently, by driving the rotating rod 12 to rotate, the disc 13 is driven to rotate, thereby driving the connecting block 14 and the turntable 18 to rotate, and the rotation of the turntable 18 drives the connecting rod 193 to rise. When the turntable 18 rotates to a certain angle, it will drive the connecting rod 193 to move downward, so that the sliding rod 192 reciprocates up and down in the first fixed plate 191, and then drive the spray head 196 to reciprocate up and down, so as to complete the painting, so that the sheet metal will not be scratched during the painting, thereby improving the work efficiency and reducing the number of rework; when it is necessary to spray paint on sheet metals of different sizes, by rotating the first screw rod 16, the dovetail block 17 is driven to descend in the dovetail groove 15, thereby driving the turntable 18 to descend, so that the rotation eccentric distance of the turntable 18 becomes larger, thereby increasing the distance of the up and down reciprocating movement of the sliding rod 192, and then making the spraying range of the spray head 196 larger. When you want to reduce the spraying range of the spray head 196, reverse the operation.

[0037] Finally, by providing the slide plate 3 and the second slide groove 31, the placement table 23 can move more stably, thereby ensuring that the sheet metal can be more uniform during painting, thereby improving the quality of painting.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
