Description

Technical Field

[0001] This invention belongs to the field of spraying machine technology, specifically an automatic spraying machine for workpieces. Background Technology

[0002] In some existing factories, when spraying workpieces, the workpieces need to be placed at the loading station, and then transported to the work station by a rotating mechanism or manually. The outer surface of the workpiece is then sprayed using a spray gun. However, many workpieces often require spraying all surfaces, which requires workers to use clamping tools to flip the workpiece so that the spray gun can spray the bottom and top surfaces. This method has poor continuous operation capability, high labor intensity, and low efficiency. Therefore, we propose an automatic workpiece spraying machine. Summary of the Invention

[0003] The purpose of this invention is to reduce the labor intensity of workers and improve production efficiency and product quality. This application provides an automatic workpiece spraying machine.

A lead screw motor and a sliding rod are fixedly connected to the inner wall of the top of the first channel. A lead screw is fixedly connected to the output end of the lower surface of the lead screw motor. The end of the lead screw away from the lead screw motor is rotatably connected to the inner bottom surface of the first channel through a bearing. A moving block is threadedly connected to the outer surface of the lead screw. A second motor is fixedly connected to the outer surface of the moving block. A second rotating shaft is fixedly connected to the output end of the second motor. A circular plate is fixedly connected to the outer surface of the second rotating shaft away from the second motor. Two long plates are symmetrically fixed to the side of the circular plate away from the second rotating shaft. A convex plate is fixedly connected to the side of the two long plates away from each other. An inner cavity is opened inside the convex plate. A second channel is opened inside the long plate. The interior of the inner cavity is connected to the interior of the second channel. An electric cylinder is fixedly connected to the inner surface of the inner cavity. A piston rod is installed at the output end of the electric cylinder. The end of the piston rod away from the electric cylinder extends into the second channel and is fixedly connected to a clamping plate.

[0006] In a preferred embodiment of the invention, an inner cavity is formed inside the bottom end of the storage plate, and a motor is installed inside the inner cavity. A rotating shaft is fixedly connected to the upper surface output end of the motor, and the end of the rotating shaft away from the motor extends into the groove and is fixedly connected to the lower surface of the disc.

[0007] In a preferred embodiment of the invention, a paint chamber is provided inside the upper end of the spray box, and a material pump is installed on the upper inner wall of the paint chamber. The outlet of the material pump is connected to the internal cavity of the spray nozzle, and the inlet of the material pump is connected to a conveying pipe. The end of the conveying pipe away from the material pump extends to the bottom of the paint chamber.

[0008] In a preferred embodiment of the invention, a feed pipe is provided on the upper surface of the spray box, and the internal cavity of the feed pipe is connected to the paint chamber.

[0009] In a preferred embodiment of the invention, one end of the slide rod away from the inner wall of the top of the through groove is fixedly connected to the inner wall of the bottom of the through groove, and a slider is slidably connected to the outer surface of the slide rod.

[0010] In a preferred embodiment of the invention, a connecting rod is fixedly connected between the slider and the outer surface of the movable block.

[0011] In a preferred embodiment of the invention, the input terminals of the lead screw motor, the second motor, and the electric cylinder are electrically connected to an external power source.

[0012] In a preferred embodiment of the invention, the power source of the belt conveyor is a drive motor.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0016] 1. In this invention, when the worker places the workpiece on the upper surface of the belt conveyor, the belt conveyor will drive the workpiece towards the feed inlet of the elevator. The elevator will lift the workpiece and guide it from the discharge outlet to the inside of the vibratory plate. The vibratory plate can sort the products in a consistent direction and then convey them sequentially to the grooves on the storage plate through the workpiece pushing device. After entering the grooves, the workpieces will be linearly arranged on several discs. At this time, the lead screw motor can be started to rotate the lead screw, and the moving block can move downward under the action of the lead screw until the two long plates are located on both sides of the workpiece. Then, the two electric cylinders can be started to drive the two piston rods to move the two clamping plates closer to each other until the two clamping plates clamp the workpiece from both sides. Then, the second motor can be started to drive the second rotating shaft to rotate the disc. The rotating disc can drive the clamped workpiece to rotate through the long plates until the bottom and top surfaces of the workpiece are at the same level as the spray nozzles on both sides. Finally, the bottom and top surfaces of the workpiece can be sprayed through the spray nozzles. The combination of the above structures can reduce the labor intensity of the workers and improve production efficiency and product quality.

[0017] 2. In this invention, when it is necessary to spray the outer surface of the workpiece, the motor can be started to drive the rotating shaft to rotate the disc. The rotating disc can drive the workpiece to rotate. At the same time as the workpiece rotates, the feed pump can be started to draw the paint in the paint tank through the delivery pipe. The drawn paint can be sprayed out from the spray nozzle to spray the rotating workpiece. Through the combination of the above structures, the labor intensity of the workers can be reduced, and the production efficiency and product quality can be improved. Attached Figure Description

[0030] Example:

[0031] Reference Figure 1 An automatic workpiece spraying machine includes a workbench 1 and a workbench 2. The workbench 2 is fixedly connected to the left side of the workbench 1. A belt conveyor 3 is installed on the right end of the upper surface of the workbench 1. The power source of the belt conveyor 3 is a drive motor. A hoist 4 is installed on the left end of the upper surface of the workbench 1. A vibratory feeder 5 is installed on the upper surface of the workbench 2. The upper opening of the vibratory feeder 5 is located directly below the output opening of the hoist 4. When the operator places the workpiece on the upper surface of the belt conveyor 3, the belt conveyor 3 will drive the workpiece to move towards the feed port of the hoist 4. The hoist 4 will lift the workpiece and guide it from the discharge port to the inside of the vibratory feeder 5.

[0032] Reference Figure 1 and Figure 2 The bottom cavity of the vibratory feeder 5 is connected to a workpiece pushing device 6. The lower surface of the workpiece pushing device 6 is fixedly connected to the upper surface of the worktable 2. The end of the workpiece pushing device 6 away from the vibratory feeder 5 is connected to a storage plate 7. The lower surface of the storage plate 7 is fixedly connected to the upper surface of the worktable 2. The upper surface of the storage plate 7 is provided with a groove 13. The vibratory feeder 5 can sort the products in the same direction and transport them sequentially into the groove 13 on the storage plate 7 through the workpiece pushing device 6. Several discs 14 are installed on the inner bottom surface of the groove 13. The workpieces after entering the groove 13 will be linearly arranged on the several discs 14.

[0033] Reference Figure 1 , Figure 7 and Figure 8The bottom of the storage plate 7 has an inner cavity 10. A motor 11 is installed inside the inner cavity 10. A rotating shaft 12 is fixedly connected to the output end of the upper surface of the motor 11. The end of the rotating shaft 12 away from the motor 11 extends into the groove 13 and is fixedly connected to the lower surface of the disc 14. When it is necessary to spray the outer side of the workpiece, the motor 11 can be started to make the rotating shaft 12 drive the disc 14 to rotate. The rotating disc 14 can drive the workpiece to rotate.

[0034] Reference Figures 7-9 Spraying boxes 8 are fixedly connected to the upper surfaces of the workbenches 2 on both sides of the storage plate 7. Spray nozzles 9 are installed on the upper part of the side faces of the two spraying boxes 8 that are close to each other. A paint chamber 33 is located inside the upper end of each spraying box 8. An inlet pipe 36 is provided on the upper surface of each spraying box 8, and the internal cavity of the inlet pipe 36 is connected to the paint chamber 33, allowing paint to be added into the paint chamber 33.

The number of spray nozzles 9 is twice that of the disc 14, and several spray nozzles 9 are symmetrically arranged on one side of the two spray boxes 8 that are close to each other. While the workpiece is rotating, the conveying pump 35 can be started to draw the paint inside the paint chamber 33 through the conveying pipe 34. The drawn paint can be sprayed out from the spray nozzles 9 to spray the rotating workpiece. The combination of the above structures can reduce the labor intensity of the workers and improve production efficiency and product quality.

[0035] Reference Figures 3-5 A fixed plate 15 is fixedly connected to the upper left surface of the workbench 2. A through groove 16 is formed inside the fixed plate 15.

A lead screw 19 is fixedly connected to the output end of the lower surface of the lead screw motor 17. The end of the lead screw 19 furthest from the lead screw motor 17 is rotatably connected to the inner bottom surface of the through groove 16 via a bearing. The input end of the lead screw motor 17 is electrically connected to an external power source. Starting the lead screw motor 17 causes the lead screw 19 to rotate. A moving block 20 is threadedly connected to the outer surface of the lead screw 19, and the moving block 20 can... The slide block 20 moves downward under the rotation of the lead screw 19; the end of the slide rod 18 away from the inner wall of the top of the through groove 16 is fixedly connected to the inner wall of the bottom of the through groove 16. A slider 22 is slidably connected to the outer surface of the slide rod 18. A connecting rod 21 is fixedly connected between the slider 22 and the outer surface of the moving block 20. While the moving block 20 moves downward, it can drive the slider 22 to slide on the outer surface of the slide rod 18 through the connecting rod 21. The cooperation of the slide rod 18, the connecting rod 21 and the slider 22 can guide the movement of the moving block 20 and prevent the moving block 20 from rotating in the same direction as the lead screw 19.

[0036] Reference Figures 4-6 A motor 23 is fixedly connected to the outer surface of the moving block 20. A rotating shaft 24 is fixedly connected to the output end of the motor 23. A circular plate 25 is fixedly connected to the outer surface of the rotating shaft 24 away from the motor 23. Two long plates 26 are symmetrically fixed to the side of the circular plate 25 away from the rotating shaft 24. The downward moving block 20 will drive the two long plates 26 to move down to both sides of the workpiece through the motor 23, rotating shaft 24, and circular plate 25. A protruding plate 27 is fixedly connected to the side of the two long plates 26 away from each other. The protruding plate 27 has an inner cavity 28. The long plates 26 have through grooves 29. The interior of the inner cavity 28 is connected to the interior of the through groove 29. An electric cylinder 30 is fixedly connected to the inner surface of the inner cavity 28.

The input ends of the motor 23 and the electric cylinder 30 are electrically connected to an external power source. When the two electric cylinders 30 are started, the two piston rods 31 drive the two clamping plates 32 to move closer to each other until the two clamping plates 32 clamp the workpiece from both sides. Then, the motor 23 can be started to drive the rotating shaft 24 to rotate the circular plate 25. The rotating circular plate 25 can drive the clamped workpiece to rotate through the long plate 26 until the bottom and top surfaces of the workpiece are at the same level as the spray nozzles 9 on both sides. Finally, the bottom and top surfaces of the workpiece can be sprayed through the spray nozzles 9. Through the cooperation of the above structures, different surfaces of the workpiece can be sprayed, thereby reducing the labor intensity of the workers and improving production efficiency and product quality.

[0037] The implementation principle of an embodiment of an automatic workpiece spraying machine of this application is as follows:

[0038] When using this equipment, an external power supply is required. Workers can then place the workpieces on the upper surface of the belt conveyor 3. The belt conveyor 3 will move the workpieces towards the feed inlet of the elevator 4. The elevator 4 will lift the workpieces and guide them from the discharge outlet to the vibratory feeder 5. The vibratory feeder 5 can sort the products in a consistent direction and, through the workpiece pushing device 6, sequentially transport them to the grooves 13 on the storage plate 7. After entering the grooves 13, the workpieces will be linearly arranged on several discs 14. Then, the motor 11 can be started to rotate the rotating shaft 12, causing the discs 14 to rotate. The rotating discs 14 can rotate the workpieces. Simultaneously, the feed pump 35 can be started to draw paint from the paint tank 33 through the conveying pipe 34. The drawn paint can be sprayed from the spray nozzle 9 to coat the rotating workpieces. This combination of structures can reduce the labor intensity of workers and improve production efficiency and product quality.

[0039] After the outer surface spraying is completed, the lead screw motor 17 can be started to rotate the lead screw 19. The moving block 20 can move downward under the rotation of the lead screw 19 until the two long plates 26 are located on both sides of the workpiece. Then, the two electric cylinders 30 can be started to drive the two piston rods 31 to move the two clamping plates 32 closer to each other until the two clamping plates 32 clamp the workpiece from both sides. Then, the second motor 23 can be started to drive the rotating shaft 24 to rotate the circular plate 25. The rotating circular plate 25 can drive the clamped workpiece to rotate through the long plates 26 until the bottom and top surfaces of the workpiece are at the same level as the spray nozzles 9 on both sides. Finally, the bottom and top surfaces of the workpiece can be sprayed through the spray nozzles 9. Through the cooperation of the above structures, different surfaces of the workpiece can be sprayed, thereby reducing the labor intensity of the workers and improving production efficiency and product quality.
