Description

Technical Field

[0001] The invention relates to the field of sealing ring processing, and in particular to a spraying device for producing sealing rings. Background Art

[0002] O-rings are made of fluorine rubber, nitrile rubber, silicone rubber, EPDM rubber, bis(fluoro rubber) rubber and other materials. They are widely used in various machines and are resistant to various petroleum-based oils and various chemical media. They are used to be installed on various mechanical equipment and play a sealing role in a static or moving state under specified temperature and pressure and in different liquids and gases.

[0003] In order to increase the anti-corrosion effect and overall sealing performance of rubber sealing rings, Teflon is sprayed on the surface of the sealing rings. In the traditional spraying process, for smaller sealing rings, a rotary sprayer can be used for spraying. However, when spraying some larger sealing rings, there is no relevant device, so they can only be hung up and then sprayed with a handheld nozzle. During the spraying process, it is difficult to ensure the distance between the nozzle and the sealing ring. In addition, it is impossible to ensure that the spraying time for each position is the same, which will affect the actual spray coating thickness. The uneven thickness of the spray coating will lead to poor quality of the finished product. Summary of the invention

The dust removal mechanism includes a first arc-shaped cavity 34 arranged in the notch tube 26, and a plurality of exhaust ports 33 are opened on the inner wall of the first arc-shaped cavity 34. The rear side of the vertical plate 2 is fixedly connected to the first piston cylinder 11, and a fourth piston block 46 that can slide up and down is arranged in the first piston cylinder 11.

The first piston cylinder 11 is fixedly connected to the first piston cylinder 11, and the fourth piston block 46 is rotatably connected to the first piston cylinder 11. 1 is connected to the first arc-shaped cavity 34 through the second one-way tube 14, the inner top space of the first piston cylinder 11 is connected to the first one-way tube 12, the right side of the connecting plate 8 is fixedly connected to the filter box 15, the other end of the first one-way tube 12 is connected to the inner top space of the filter box 15, a second arc-shaped cavity 35 is provided in the notch tube 26, a plurality of air inlets 32 are provided in the second arc-shaped cavity 35, the inner bottom space of the filter box 15 is connected to the second arc-shaped cavity 35 through the air inlet pipe 23, and the second arc-shaped cavity 35 is located above the first arc-shaped cavity 34;

[0037] As an embodiment of the present invention, a one-way valve is installed in each of the first one-way tube 12 and the second one-way tube 14. The one-way valve in the second one-way tube 14 flows in a direction that allows the first piston cylinder 11 to enter the first arc-shaped cavity 34 in one direction, and the one-way valve in the first one-way tube 12 flows in a direction that allows the filter box 15 to enter the top space of the first piston cylinder 11 in one direction.

[0038] As an embodiment of the present invention, it also includes reciprocating forward and reverse rotation, which is used to improve the comprehensiveness of the spraying mechanism and the dust removal mechanism. The reciprocating forward and reverse rotation includes a first notch ring 27 fixedly connected to the outside of the notch tube 26, and a plurality of tooth grooves 28 are provided on the outside of the first notch ring 27. The upper end of the connecting plate 8 is fixedly connected to a rectangular plate 18, and a columnar groove 19 is provided on the front side of the rectangular plate 18. A first piston block 30 that can slide back and forth is arranged in the columnar groove 19. A rack 21 is fixedly connected to the front side of the first piston block 30, and the rack 21 cooperates with the plurality of tooth grooves 28. A U-shaped guide rod 22 is fixedly connected to the front side of the rack 21, and the other end of the U-shaped guide rod 22 passes through the rectangular plate 18 and is slidably connected to the rectangular plate 18.

[0039] As an embodiment of the present invention, the inner top of the first piston cylinder 11 is fixedly connected to the second piston cylinder 44, and a third piston block 45 that can slide up and down is arranged in the second piston cylinder 44. The third piston block 45 and the fourth piston block 46 are fixedly connected by a piston rod. The top space of the second piston cylinder 44 is connected to the rear space of the columnar groove 19 through a connecting pipe 13. In order to make the transmission efficiency better, the top space of the second piston cylinder 44, the connecting pipe 13 and the rear space of the columnar groove 19 are all filled with hydraulic oil. In addition, the connecting pipe 13, the first one-way tube 12 and the second one-way tube 14 are all soft tube bodies.

[0040] In the present invention, when it is used, the staff first sets the rubber sealing ring on the two rotating disks 4, at which time the rubber sealing ring is in a relatively loose state, and then starts the electric telescopic rod 6 to shrink, thereby driving the upper rotating disk 4 to move upward, and the entire rubber sealing ring can be tightened, so that the inner side of the rubber sealing ring is in close contact with the two annular grooves 7, and at this time, one side of the rubber sealing ring is located at the inner side of the notch tube 26;

[0041] Then, the motor 10 is started, and the motor 10 drives the crankshaft 16 to rotate. The rotation of the crankshaft 16 causes the rotating disk 4 below to rotate through the reduction gearbox. The rotation direction is clockwise from the front to the rear. By utilizing the friction force, the rotation of the rotating disk 4 drives the tightened rubber sealing ring to rotate clockwise as a whole.

[0042] The rotation of the crankshaft 16 will cause the fourth piston block 46 to reciprocate up and down through the connecting strip 17. When the fourth piston block 46 moves up, it will press the gas into the first arc-shaped cavity 34 through the second one-way tube 14, so that the multiple exhaust ports 33 are discharged from the high-pressure mechanism, and the air flow is cleaned on the outer side of the moving rubber sealing ring, and the dust attached to the surface of the rubber sealing ring is blown off. When the fourth piston block 46 moves down, the air in the filter box 15 will be sucked away through the first one-way tube 12, and the negative pressure will be used to draw the air flow inside the notch tube 26 into the filter box 15 through the multiple air inlets 32. In this way, in actual use, the up and down reciprocating motion of the fourth piston block 46 can first blow up the dust on the rubber sealing ring and then suck it away. On the basis of ensuring efficient cleaning, it avoids the situation where the dust is attached to the rubber sealing ring again, thereby improving the actual cleaning effect.

[0043] After the motor 10 is started for a period of time, the external spray pump is started. The spray pump can draw in the external paint and then press it into the third arc-shaped cavity 42. When the paint is injected into the third arc-shaped cavity 42, the internal pressure increases, and then the paint is pressed into the connecting column 38 through the connecting port 43 and sprayed out from the injection channel. Since the injection channel on the connecting column 38 is thinner, the second piston block 37 and the connecting column 38 will move away from the third arc-shaped cavity 42 under the action of pressure when spraying, so that multiple connecting columns 38 are close to the moving rubber sealing ring. Finally, when the ball 40 contacts the rubber sealing ring, the corresponding connecting column 38 stops moving. Since the entire rubber ring is in a taut state, the actual distance between the multiple connecting columns 38 and the part to be sprayed of the rubber sealing ring is the same when spraying.

[0044] In addition, the up and down reciprocating motion of the fourth piston block 46 will cause the third piston block 45 to reciprocate up and down through the piston rod, and the use of the connecting pipe 13 can cause the first piston block 30 to reciprocate forward and backward. The back and forth reciprocating motion of the first piston block 30 will cause the first notch ring 27 to drive the notch tube 26 to reciprocate forward and reverse through the cooperation of the rack 21 and the tooth groove 28. In this way, when in specific use, the spraying of multiple connecting columns 38, the exhaust of multiple air inlets 32, and the blowing of multiple exhaust ports 33 are all in a rotating state, and with the continuous movement of the rubber sealing ring, the spraying and cleaning can be extremely uniform;

[0045] Since the multiple connecting columns 38 rotate back and forth in the forward and reverse directions during spraying, and the entire rubber sealing ring is still in motion, the overall spraying distance is the same and the spraying time is close, so that the actual spraying thickness is relatively uniform, the final product quality is relatively good, and it can adapt to sealing rings of different thicknesses, and the overall adaptability is excellent. If the actual spraying thickness needs to be adjusted, it is only necessary to control the pumping volume per unit time of the spray pump;

[0046] After the overall spraying is completed, the electric telescopic rod 6 is started to extend, and then the rubber sealing ring is removed.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
