Technical Field

[0001] The utility model belongs to the technical field of spraying machines, and particularly relates to a spraying machine with an adjustable spraying range. Background Art

[0002] A spraying machine is a device used for coating surfaces and is widely applied in industrial production and manufacturing processes. It applies paint or a paint mixture to the surface of a workpiece in a spraying manner to achieve protective, decorative, or functional coatings of different materials. The publication number CN217069297U discloses a spraying machine, which includes a mounting plate, a mixing mechanism and a delivery pump respectively mounted on the upper surface of the mounting plate. The discharge port of the mixing mechanism is communicated with the delivery pump. An installation frame is provided on the upper surface of the mounting plate. A winding mechanism is rotatably mounted on opposite sides of the installation frame. The winding mechanism includes a hollow sleeve rod. The output end of the delivery pump is mounted with a connecting pipe. The connecting pipe is rotatably connected to one end of the sleeve rod through a connector. The other end of the sleeve rod is connected to an output pipe. A chuck for fixing the output pipe is mounted on the surface of the sleeve rod.

[0034] In one embodiment of the present utility model, as Figures 1-4As shown in the figure, a spraying machine with an adjustable spraying range is provided, including a bottom plate 1 and a spray head 2. A storage tank 3 is fixedly installed on the upper surface of the bottom plate 1. A feed pipe 4 is fixedly installed on the upper surface of the storage tank 3. A water pump 5 is fixedly installed on the upper surface of the bottom plate 1. The suction end of the water pump 5 extends into the interior of the storage tank 3. The discharge end of the water pump 5 is fixedly connected to a connecting hose 6. A column 7 is fixedly installed on the upper surface of the bottom plate 1. A driving motor 1 8 is fixedly installed on the upper surface of the column 7. A first threaded rod 9 is rotatably connected inside the column 7. A sliding block 10 is slidably connected inside the column 7. A connecting block 11 is fixedly installed on the side surface of the sliding block 10. An installation sleeve 12 is fixedly installed on the side surface of the connecting block 11. A sliding rod 13 is fixedly installed on the surface of the column 7. A driving motor 2 14 is fixedly installed on the upper surface of the installation sleeve 12. The output end of the driving motor 2 14 is fixedly installed with a driving gear 15. A rotating rod 16 is fixedly installed inside the spray head 2. A driven gear 17 is fixedly installed at one end of the rotating rod 16. A handle 18 is fixedly installed on the side surface of the bottom plate 1, which is convenient for the user to push. Universal wheels 19 are symmetrically and fixedly installed on the lower surface of the bottom plate 1, which is convenient for moving the spraying machine. The output end of the driving motor 1 8 is fixedly connected to one end of the first threaded rod 9. The first threaded rod 9 is threadedly connected to the sliding block 10. By rotating the threaded rod, the sliding block 10 slides inside the column 7. The sliding block 10 drives the connecting block 11 to move up and down, thereby realizing the up and down adjustment of the spray head 2. The spray head 2 is rotatably connected to the installation sleeve 12. The rotating rod 16 is rotatably connected to the installation sleeve 12. By means of the rotating rod 16, the spray head 2 rotates more smoothly inside the installation sleeve 12. The connecting block 11 is slidably connected to the sliding rod 13. By means of the sliding rod 13, the connecting block 11 moves more stably up and down. The driving gear 15 and the driven gear 17 are meshed and driven. By the meshing of the driving gear 15 and the driven gear 17, the rotating rod 16 rotates, thereby realizing the angle adjustment of the spray head 2.

[0035] As Figure 1 , 2As shown in FIGS. 5, a connecting rod 20 is slidably connected inside the storage bin 3. One end of the connecting rod 20 is fixedly connected to a scraping plate 21, and a connecting plate 22 is fixedly installed at one end of the connecting rod 20. A third driving motor 23 is fixedly installed on the side of the storage bin 3, and a first fixing plate 24 is fixedly installed on the side of the storage bin 3. A second threaded rod 25 is rotatably connected inside the first fixing plate 24. A second fixing plate 24 is fixedly installed on the side of the storage bin 3, and a limiting rod 27 is fixedly installed on the surface of the second fixing plate 24. The inner wall of the storage bin 3 can be effectively cleaned by the scraping plate 21 to prevent the paint from caking or blocking the nozzle in the bin, which not only improves the spraying efficiency and accuracy, but also reduces the production cost and maintenance time. The scraping plate 21 is in contact with the inner wall of the storage bin 3. The output end of the third driving motor 23 is fixedly connected to the second threaded rod 25. The connecting plate 22 is threadedly connected to the second threaded rod 25. The limiting rod 27 is slidably connected to the connecting plate 22 away from the third driving motor 23. By driving the second threaded rod 25 to rotate through the third driving motor 23, the connecting plate 22 drives the connecting rod 20 to move up and down, so that the scraping plate 21 slides on the inner wall of the storage bin 3, realizing the scraping of the paint on the inner wall of the storage bin 3.

[0036] Working principle: When in use, first start the water pump 5 to pump out the paint inside the storage tank 3. The pumped paint enters the connecting hose 6 from the discharge end of the water pump 5 and then sprays out from the spray head 2. When it is necessary to adjust the height of the spray head 2, first start the first driving motor 8. The first driving motor 8 will drive the first threaded rod 9 to rotate. Since the sliding block 10 is threadedly connected to the first threaded rod 9, the sliding block 10 moves up and down inside the column 7. The sliding block 10 drives the connecting block 11 and the mounting sleeve 12 to move up and down. At the same time, the connecting block 11 slides on the surface of the sliding rod 13, making the connecting block 11 more stable during the movement, so as to realize the adjustment of the height of the spray head 2. When it is necessary to adjust the angle of the spray head 2, first start the second driving motor 14. The second driving motor 14 will drive the driving gear 15 to rotate. Since the driving gear 15 and the driven gear 17 are meshed with each other, the driven gear 17 drives the rotating rod 16 to rotate. The rotating rod 16 drives the spray head 2 to rotate, so as to realize the adjustment of the angle of the spray head 2. By adjusting the height and angle of the spray head 2, the spraying range of the spraying machine is adjusted, avoiding the problems that the spray head 2 may waste paint due to too large a spraying range or too small a spraying range, which requires multiple angle adjustments and repeated spraying, greatly increasing the workload, effectively reducing unnecessary paint use, saving costs and resources. When the third driving motor 23 is started, the third driving motor 23 will drive the second threaded rod 25 to rotate. Since the connecting plate 22 is threadedly connected to the second threaded rod 25, the second threaded rod 25 drives the connecting plate 22 to move up and down. The connecting plate 22 drives the connecting rod 20 to move up and down, so that the scraping plate 21 slides on the inner wall of the storage tank 3. At the same time, the limiting rod 27 slides inside the connecting plate 22 away from the third driving motor 23, thereby improving the stability of the scraping plate 21 during the sliding on the inner wall of the storage tank 3, so as to realize the scraping of the paint on the inner wall of the storage tank 3, ensuring the mixing uniformity of the paint, reducing the residue of the paint inside the equipment, thereby reducing the risk of wear and blockage of the equipment, which helps to extend the service life of the spraying equipment and reduce the frequency of maintenance and repair.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
