DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In order to address the shortcomings of the existing technology, such as Figure 1-9 As shown, the present invention provides a mechanical parts spraying device, including a recycling box 1, a spraying chamber 2 is fixedly provided on the top of the recycling box 1, a spraying mechanism and an air drying mechanism are provided inside the spraying chamber 2, and a regulating component 3 is provided on the top of the spraying chamber 2;

[0036] The spraying mechanism includes a storage box 4 fixedly mounted on the top of the spraying chamber 2, a cover plate 15 is installed on the top of the storage box 4 by bolts, the regulating component 3 includes an air inlet cylinder 301 fixedly mounted on the top of the cover plate 15, and a lower air vent 307 connecting the storage box 4 and the air inlet cylinder 301 is opened on the cover plate 15;

[0037] The paint used for spraying is placed inside the storage box 4, and air is injected into the storage box 4 through the air inlet cylinder 301 and the lower air vent 307. The paint inside the storage box 4 is pressurized by air pressure, so that the paint inside the storage box 4 can be sprayed out.

[0038] For intermittent spraying, such as Figure 1 , 4 As shown in FIG. 5 , a partition plate 306 is fixedly provided on the inner wall of the air inlet cylinder 301, and an air guide pipe 309 connected to the air drying mechanism is fixedly provided on the rear side of the air inlet cylinder 301. The air guide pipe 309 and the lower air vent 307 are respectively located on both sides of the partition plate 306;

[0039] A rotatable turntable 304 is provided inside the air intake cylinder 301, a sealing gasket in contact with a partition 306 is fixedly provided at the bottom end of the turntable 304, an outer end of the turntable 304 is in contact with the inner wall of the air intake cylinder 301, an upper air vent 305 is provided on the turntable 304, an air intake pipe 308 capable of injecting air into the air intake cylinder 301 is fixedly provided on the rear side of the air intake cylinder 301, and the air intake pipe 308 is located on the top of the turntable 304.

[0040] The air intake pipe 308 is fixedly provided with an air pump 16, the top of the air intake cylinder 301 is provided with a detachable sealing cover 302, and the top of the sealing cover 302 is provided with a second motor 12;

[0041] A driving shaft 303 is fixedly disposed on the top of the rotating disk 304. The driving shaft 303 extends to the top of the sealing cover 302 and is fixedly connected to the output shaft of the second motor 12.

[0042] A pressure relief pipe with a one-way valve is fixedly provided on the front side of the air intake cylinder 301. The pressure relief pipe and the lower air hole 307 are on the same side of the partition 306. The air intake volume of the air intake pipe 308 is greater than the air outlet volume of the pressure relief pipe. Therefore, when air is injected, a part of the air is discharged through the pressure relief pipe, and the air remaining in the air intake cylinder 301 enters the turntable 304 through the lower air hole 307 to pressurize the paint. When the upper air hole 305 is moved away from the side where the lower air hole 307 is located, the air remaining in the air intake cylinder 301 can also be discharged through the pressure relief pipe to stop pressurizing the paint.

[0043] During the spraying process, the air pump 16 drives the air from the air inlet pipe 308 into the air inlet cylinder 301, and the air needs to pass through the upper air hole 305 to pass through the turntable 304. Driven by the second motor 12, the drive shaft 303 rotates and controls the turntable 304 to rotate, thereby driving the upper air hole 305 to rotate. When the upper air hole 305 rotates to the side of the lower air hole 307, the air enters the storage box 4 through the lower air hole 307 to pressurize the paint for spraying. When the upper air hole 305 rotates to the side where the air duct 309 is located, the air passing through the upper air hole 305 is transmitted to the air drying mechanism through the air duct 309 to air-dry the parts in the spraying gap. This cycle is repeated, and spraying is performed intermittently, spraying and air-drying at the same time to prevent too much undried paint from remaining on the surface of the parts and flowing and causing uneven coating thickness.

[0044] The paint is atomized and sprayed onto the parts, such as Figure 4As shown, a plurality of main pipes 14 are fixedly provided at the bottom end of the storage box 4, and the bottom ends of the main pipes 14 extend into the interior of the regulating component 3. Two one-way valves are fixedly provided on the main pipes 14, and two branch pipes 17 are fixedly provided at the outer end of the main pipe 14. A nozzle 18 is fixedly provided at one end of the branch pipe 17, and the branch pipe 17 is located between the two one-way valves on the main pipe 14.

[0045] A connecting channel 9 is provided inside the recovery box 1, and the bottom end of the main pipeline 14 is fixedly connected to the connecting channel 9. A water injection pipe with a quick connector is fixedly provided on the front side of the connecting channel 9, which can inject water into the main pipeline 14 for cleaning.

[0046] The pressurized paint flows into the spray chamber 2 through the main pipe 14, and then flows to the nozzle 18 through the branch pipe 17. The nozzle 18 atomizes the liquid and sprays it out for spraying. After the spraying work is completed, water can be injected into the connecting channel 9 through the water injection pipe. The water entering the connecting channel 9 is finally sprayed out from the nozzle 18 through the main pipe 14 and the branch pipe 17. After the work is completed, the branch pipe 17 and the nozzle 18 are cleaned to avoid blockage after the paint solidifies.

[0047] Use air drying mechanism to make the paint solidify quickly on the surface of parts, such as Figure 4 , 6 As shown, the air-drying mechanism includes an air-drying chamber 19 fixedly mounted on the inner rear wall of the spray chamber 2, one end of the air duct 309 is fixedly connected to the air-drying chamber 19, a plurality of partition bars 20 are fixedly mounted on the inner wall of the air-drying chamber 19, and a downwardly inclined air duct is provided between two adjacent partition bars 20, so as to blow air toward the sprayed parts.

[0048] The air transported through the air guide pipe 309 reaches the air drying chamber 19 and then is blown out obliquely downward through the air duct and blown toward the parts in the spraying gap, thereby accelerating the solidification of the paint and achieving the purpose of air drying.

[0049] Excess paint needs to be cleaned and recycled. Figure 1 , 3 As shown in , 7 and 9, two closed doors 6 are installed on the front side of the spray room 2 through hinges, and an inspection plate is installed on the front side of the recovery box 1 through bolts;

[0050] A placement component 13 is provided inside the recycling box 1, and the placement component 13 is located directly below the storage box 4. The parts to be sprayed are placed on the top of the placement component 13. A first motor 5 is installed on one side of the recycling box 1. The output shaft of the first motor 5 extends into the recycling box 1 and is movably connected to the recycling box 1 through a sealed bearing.

[0051] The placement assembly 13 includes an outer frame 1301, and the output shaft of the first motor 5 is fixedly connected to the outer frame 1301, so that the placement assembly 13 can be controlled to flip as a whole. A plurality of horizontally arranged load-bearing rods 1302 are fixedly provided on the inner wall of the outer frame 1301;

[0052] Both ends of the load-bearing rod 1302 are provided with an electromagnet 1305 embedded in the inner wall of the outer frame 1301, and the outer end of the load-bearing rod 1302 is sleeved with an iron slide seat 1303, and both ends of the iron slide seat 1303 are fixed with sponge rings 1304, which can absorb paint for the purpose of recycling.

[0053] During the spraying process, the part is placed on the load-bearing rod 1302 of the placement component 13, and part of the paint sprayed from top to bottom is sprayed on the surface of the part, and the other part sticks to the load-bearing rod 1302 or falls into the recovery box 1 through the gap between the load-bearing rods 1302, so that the paint can be recycled. After a part is sprayed, the outer frame 1301 can be driven to flip by the first motor 5, so that the regulating component 3 can be flipped as a whole. In this way, the paint stuck to the top of the load-bearing rod 1302 will be located at the bottom of the load-bearing rod 1302 after rotation, and it is easier to drip into the recovery box 1 under the action of gravity. In the collection box 1, the electromagnet 1305 on one side can be energized at the same time, and the magnetic force of the electromagnet 1305 attracts the iron slide 1303 to move along the load-bearing rod 1302. During the movement, the paint remaining on the load-bearing rod 1302 will be absorbed in the sponge ring 1304 until the sponge ring 1304 at one end contacts the electromagnet 1305. At this time, the magnetic force of the electromagnet 1305 squeezes the sponge ring 1304, and the paint adsorbed therein is squeezed out and falls into the recycling box 1, thereby improving the recycling efficiency and making the cleaning effect of the load-bearing rod 1302 better.

[0054] Recycled paint can also be reused, such as Figure 1 , 9 As shown, a recovery pipe 11 is provided on one side of the recovery box 1, and an air pump 7 is fixedly provided on the recovery pipe 11. A recovery cylinder 8 is provided on one side of the recovery box 1, and a detachable cylinder cover 10 is installed on the top of the recovery cylinder 8. One end of the recovery pipe 11 passes through the cylinder cover 10 and extends to the inside of the recovery cylinder 8 to recover excess paint. An exhaust pipe is fixedly provided on the top of the cylinder cover 10.

[0055] While spraying, the vacuum pump 7 can also be turned on to extract the air entering the spray room 2 and the recovery box 1 and the paint mixed in the air along the recovery pipe 11. The recovery tube 8 is filled with the same paint. The recovery pipe 11 injects the mixture of air and paint into the paint. The paint in the air remains in the recovery tube 8 and can be reused. The air is finally discharged through the exhaust pipe.

[0056] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
