[0025] See also Figures 1 to 4 , the utility model provides a technical solution:
[0026] A paint spraying machine for workpiece processing includes a frame 1, a cylinder 2 is fixedly connected to the interior of the frame 1, a disc 3 is fixedly connected to the left side of the front end of the cylinder 2, a cavity 31 is opened inside the disc 3, a rotating shaft 32 is movably connected to the interior of the cavity 31, a baffle 321 is fixedly connected to the outside of the rotating shaft 32, the upper end of the rotating shaft 32 is fixedly connected to a cover plate 322, the upper end of the cover plate 322 is fixedly connected to a second gear 323, the upper end of the second gear 323 is movably connected to a liquid storage cylinder 33, the lower end of the liquid storage cylinder 33 is fixedly connected to a cylinder mouth 331, the second gear 323 A movable groove 324 is provided at the upper end, and a through hole 325 is provided at the lower end of the movable groove 324. The left side of the disc 3 is fixedly connected to the suction pipe 4, and the upper end of the inner part of the suction pipe 4 is fixedly connected to the stop block 34. The upper end of the stop block 34 is fixedly connected to the first gear 341, and the upper end of the first gear 341 is fixedly connected to the knob 342. The outer wall of the barrel 331 slides in contact with the inner wall of the movable groove 324, and the baffle 321 slides in contact with the inner wall of the disc 3. The second gear 323 is meshed with the first gear 341, and the stop block 34 slides in contact with the inside of the suction pipe 4.
[0027] By adopting the above technical solution, when it is necessary to spray paint on the workpiece, the paint can is opened and placed on the left side of the device, and then the suction pipe 4 is placed in the paint can. At this time, the cylinder 2 is started, and the paint in the paint can is extracted through the suction pipe 4, and then sprayed out from the spray gun 7 through the transport pipe 5 to achieve the effect of paint spraying. During the spraying operation, when it is necessary to change the color for spraying, the suction pipe 4 is wiped clean and then placed in a new paint bucket. First, turn the knob 342. The rotation of the knob 342 drives the first gear 341 to rotate. The rotation of the first gear 341 drives the stop block 34 to move, so that the stop block 34 rotates, and the stop block 34 blocks the suction pipe 4. When the first gear 341 rotates, it drives the second gear 323 to rotate. The rotation of the second gear 323 drives the cover plate 322 to rotate. The rotation of the cover plate 322 drives the rotating shaft 32 The external baffle 321 rotates, thereby blocking the left and right openings at the disc 3, and the second gear 323 rotates to make the barrel mouth 331 slide to the through hole 325 through the movable groove 324, so that the cleaning liquid in the liquid storage barrel 33 flows into the inside of the disc 3 through the through hole 325. At this time, the knob 342 is turned back to the original position to make the first gear 341 rotate, and by engaging and rotating with the second gear 323, the through hole 325 is moved away from the barrel mouth 331, thereby preventing the cleaning liquid in the liquid storage barrel 33 from flowing out. The second gear 323 rotates and brings the baffle 321 back to the original position, so that the left and right openings at the disc 3 are connected. At this time, the spray gun 7 is started, and the remaining paint in the device is passed through the transport pipe 5 and sprayed out from the spray gun 7 together with the cleaning liquid, thereby achieving the effect of cleaning the spray gun 7, the nozzle, and the paint pipeline, thereby reducing the spray replacement time and improving the paint spraying efficiency.
[0028] Specifically, such as Figure 4 As shown, a transport pipe 5 is fixedly connected to the right side of the front end of the cylinder 2, a spray gun 7 is fixedly connected to the upper end of the transport pipe 5, and a pressure limiting component 6 is provided at the lower end of the spray gun 7, and the pressure limiting component 6 includes a movable shaft 61 movably connected to the lower end of the inside of the spray gun 7, and a cylinder 62 is fixedly connected to the lower left end of the spray gun 7, and a plurality of rotating paddles 611 are fixedly connected to the outside of the movable shaft 61, and a rotating block 612 is fixedly connected to the left side of the outside of the movable shaft 61, and a plurality of sliding rods 63 are movably connected to the inside of the rotating block 612, and the outsides of the plurality of sliding rods 63 are movably connected to springs 631, and the ends of the plurality of sliding rods 63 away from the movable shaft 61 are fixedly connected to protrusions 632, and the inner wall of the cylinder 62 is fixedly connected to a clamping block 621, and the plurality of sliding rods 63 slide and fit inside the rotating block 612, and the elastic force of the spring 631 is greater than the gravity exerted on the protrusion 632, and the plurality of protrusions 632 are engaged with the clamping block 621.
[0029] By adopting the above technical solution, during the spraying operation, when the spray gun 7 is used improperly and the pressure is too high, when the paint in the transport pipe 5 passes through the pressure limiting component 6 quickly, the paint moves through the rotating paddle 611 and rotates with the rotating paddle 611, the rotating paddle 611 rotates with the movable shaft 61, the movable shaft 61 rotates with the rotating block 612, and the rotating block 612 rotates with multiple sliding rods 63, springs 631 and protrusions 632 with the movable shaft 61 as the axis and performs a circular motion. When the paint flow rate is too fast, the rotating paddle 611 rotates faster. At this time, the sliding rod 63 inside the rotating block 612 rotates in the distance generated by the rotation. Under the action of centrifugal force, multiple sliding rods 63 move toward one end away from the movable shaft 61, and the sliding rods 63 move outward, carrying the protrusions 632 with them. During the rotation process, the protrusions 632 touch the internal block 621 of the cylinder 62, thereby stopping the rotating paddle 611 through the rotating block 612. The stopping of the rotating paddle 611 increases the resistance of the paint when it passes through the rotating paddle 611, and slows down the flow rate of the paint passing through the upper end of the rotating paddle 611, so that the sprayed paint falls more evenly on the workpiece, so as to solve the problems of excessive spraying pressure, roughness, orange peel, whitening of the coating, etc., thereby improving the efficiency of paint spraying.
[0030] Working principle: During the spraying operation, when it is necessary to change the color for spraying, wipe the suction pipe 4 clean and put it in a new paint bucket. First, turn the knob 342. The rotation of the knob 342 drives the first gear 341 to rotate. The rotation of the first gear 341 drives the stop block 34 to move, so that the stop block 34 rotates. The stop block 34 blocks the suction pipe 4. When the first gear 341 rotates, it drives the second gear 323 to rotate. The rotation of the second gear 323 drives the cover plate 322 to rotate. The rotation of the cover plate 322 drives the baffle 321 outside the rotating shaft 32 to rotate, thereby blocking the left and right openings of the disc 3, and the rotation of the second gear 323 makes the barrel mouth 331 slides to the through hole 325 through the movable groove 324, so that the cleaning liquid in the liquid storage cylinder 33 flows into the inside of the disc 3 through the through hole 325. At this time, the knob 342 is turned back to the original position, so that the first gear 341 rotates, and by engaging and rotating with the second gear 323, the through hole 325 is moved away from the barrel mouth 331, thereby preventing the cleaning liquid in the liquid storage cylinder 33 from flowing out. The second gear 323 rotates and brings the baffle 321 back to the original position, so that the left and right ends of the disc 3 are connected. At this time, the spray gun 7 is started, and the remaining paint in the device and the cleaning liquid are passed through the transport pipe 5 and sprayed from the spray gun 7, thereby achieving the effect of cleaning the spray gun 7, the nozzle, and the paint pipeline.
