Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water pump shell corrosion prevention, in particular to a kind of anticorrosive paint spraying mechanism for water pump processing. BACKGROUND

[0002] As the core equipment in fluid delivery field, water pump is widely used in chemical industry, water conservancy, ocean and other industries. Its shell is exposed to humid environment for a long time or directly contacts with corrosive medium containing salt, acid and alkali, which is easy to be corroded and damaged. It not only affects the service life of the equipment, but also may cause safety hazards such as decrease of delivery efficiency and medium leakage. Therefore, shell anticorrosive spraying is an indispensable key process in water pump processing, which has multiple functions of protection, aesthetics and durability improvement.

[0003] Current mainstream automatic spraying equipment for water pump focuses on the spraying operation of the outer surface of the shell, and the original design intention fails to fully consider the anticorrosive requirement of the inner side of the water pump under special working conditions. When the water pump needs to operate in high humidity and strong corrosion environment for a long time, the inner side surface also needs to be uniformly sprayed with anticorrosive paint. However, the existing equipment lacks automatic spraying function for the inner side, and can only rely on manual operation with tools, which not only has high labor intensity and low spraying efficiency, but also has problems such as uneven coating thickness and missed spraying, so it is difficult to guarantee the protection effect. At the same time, due to the special shape and more shielding of the pump foot and flange inner surface in the structure of the water pump, the existing equipment lacks sufficient spraying coverage, and often has quality defects such as thin coating and poor adhesion, which makes these key stress and sealing parts become weak points of corrosion, seriously affecting the overall reliability and service life of the water pump. Therefore, an automatic mechanism capable of realizing all-round coverage of the inner and outer sides of the water pump and precise spraying for special parts is needed to solve the technical shortcomings of the existing equipment.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 14 As shown, a water pump processing anti-corrosion coating spraying mechanism includes a base 1, a spraying chamber 11 on the base 1, a top door 14 hinged to the top of the spraying chamber 11, an air duct 12 inside the spraying chamber 11, a hot air conveying device inside the base 1, a side channel 13 on the side of the base 1, hot air being sent into the air duct 12 through the internal pipe of the side channel 13, a conveying pump and a material bucket for supplying coating to the spraying mechanism inside the base 1, and an external pump spraying mechanism 4, an internal pump inlet spraying mechanism 5, a pump foot spraying mechanism 6, and an internal pump spraying mechanism 7 inside the spraying chamber 11. The external pump spraying mechanism 4 sprays the outer surface a and the outer shadow surface b of the rotating water pump 8, the internal pump inlet spraying mechanism 5 sprays the inner surface e of the pump inlet, the pump foot spraying mechanism 6 sprays the outer surface c of the pump foot, and the internal pump spraying mechanism 7 performs diameter-changing spraying on the inner surface d through centrifugal diameter-changing method.

[0031] This anti-corrosion coating spraying mechanism for water pump processing mainly solves the problems of existing automatic painting equipment that can only spray the outer surface of the water pump, while the inner side requires manual operation, resulting in low efficiency and quality. It also addresses the issues of uneven spraying and thin coating on parts such as pump feet and flange back surfaces. This mechanism enables all-round automatic spraying of the water pump's outer side, outer back surface, pump foot outside, inner side, and pump port inside, improving spraying uniformity and work efficiency.

[0032] Before starting the equipment, the water pump 8 is placed in the spraying chamber 11. The water pump 8 is temporarily lifted and positioned by the positioning mechanism 3, and then clamped by the clamping mechanism 2. The positioning mechanism 3 is reset, the top door 14 is closed, and the spraying operation is carried out. The spraying mechanism is started, and the outer side a and outer shadow side b of the rotating water pump 8 are sprayed by the outer side spraying mechanism 4. The outer side c of the pump foot is sprayed by the pump foot spraying mechanism 6. At the same time, the outer side of the pump port is sprayed. The inner side spraying mechanism 7 sprays the inner side d by centrifugal diameter change. The inner side spraying mechanism 5 sprays the inner side e of the pump port. After the primer is sprayed, hot air is blown out through the air duct 12 to accelerate the drying speed of the paint surface. Then, the intermediate paint and top paint are sprayed. After the spraying is completed, the water pump is lifted out and dried through the through holes on both sides of the flange.

[0033] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3As shown, the spraying chamber 11 is also equipped with a clamping mechanism 2. The clamping mechanism 2 includes a fixed base 21. Two opposing clamping platforms 25 are slidably mounted on the fixed base 21. A motor 22 is mounted on the fixed base 21. A gear 221 is mounted on the output end of the motor 22. A gear 23 that meshes with the gear 221 is rotatably mounted on the fixed base 21. Both sides of the gear 23 are coaxially connected to threaded posts 24 with opposite threads. The bottom of the two clamping platforms 25 is provided with threaded holes that mate with the threaded posts 24. A clamping plate 26 and a clamping plate 27 are rotatably mounted on the two clamping platforms 25 respectively. A motor 28 that drives the clamping plate 27 to rotate is mounted on one of the clamping platforms 25. A gear 281 is mounted on the output end of the motor 28. A gear 271 that meshes with the gear 281 is mounted on the rear end of the motor that drives the clamping plate 27.

[0034] The clamping mechanism 2 mainly solves the problems of inaccurate positioning and unstable clamping of the water pump 8 during the spraying process, as well as the inability to achieve all-round uniform spraying by rotating and adapting to various spraying mechanisms. It ensures that the water pump 8 maintains a stable posture during the spraying operation, and at the same time, by driving the water pump 8 to rotate, the outer side of the pump, the pump feet, the inner side of the pump port and other parts can be accurately sprayed.

[0035] During clamping operations, motor 22 starts and drives gear 221 to rotate. Gear 221 meshes with gear 23 on the fixed base 21, driving the threaded posts 24 on both sides of gear 23, which are coaxially connected and have opposite thread directions, to rotate synchronously. Since the threaded holes at the bottom of the two clamping platforms 25 are adapted to the corresponding threaded posts 24, the rotation of the threaded posts 24 drives the two clamping platforms 25 to slide towards each other on the fixed base 21, thereby allowing the clamping plates 26 and 27 on the two clamping platforms 25 to precisely clamp the two sides of the water pump 8. The flange of the water pump 8 is used to securely fix the water pump 8. During the spraying process, the motor 28 starts and drives the gear 4 281 to rotate. The gear 4 281 meshes with the gear 3 271 at the rear end of the clamping plate 27, which drives the clamping plate 27 to rotate. The clamping plate 1 26 is in contact with the flange of the water pump 8 and can rotate synchronously with the water pump 8. Therefore, when the clamping plate 2 27 rotates, it will drive the entire water pump 8 to rotate smoothly, providing a basis for uniform spraying for various special spraying mechanisms such as the pump outer spraying mechanism 4 and the pump foot spraying mechanism 6, ensuring that all surfaces of the water pump 8 to be sprayed can be fully covered.

[0036] Combined with appendix Figure 2 Appendix Figure 11 Appendix Figure 12 and attached Figure 13As shown, the pump inner spraying mechanism 7 includes a fixed platform 71, a movable platform 72, and a pump inner spraying arm 73. The fixed platform 71 is mounted on the base 1 and is equipped with a motor 711 and a threaded post 713. The output end of the motor 711 is equipped with a gear 712, and the end of the threaded post 713 is equipped with a gear 714 that meshes with the gear 712. The movable platform 72 moves laterally on the fixed platform 71. The bottom of the movable platform 72 is equipped with a threaded hole that mates with the threaded post 713. The pump inner spraying arm 73 is rotatably mounted on one side of the movable platform 72. The front end of the pump inner spraying arm 73 extends into the inner through hole of the clamping plate 27. The pump inner spraying arm 73 includes a rotating arm 731. The rotating arm 731 is rotatably mounted on the front end of the movable platform 72. The movable platform 72 is equipped with a motor 721 that drives the rotating arm 731 to rotate. The output end of the motor 721 is equipped with a gear 722, and the rear end of the rotating arm 731 is equipped with a gear 722 that meshes with the gear 722. The gear 7311 meshes with the 722. An end plate 738 is connected to the end of the rotating arm 731. The end plate 738 and the inner side of the end of the rotating arm 731 form a cavity 7313. A rope pulley 733 is provided inside the cavity 7313. A spiral spring 737 is provided on the rotating shafts on both sides of the rope pulley 733. Ropes 734 are wound in multiple rope grooves on the rope pulley 733. Multiple extension arms 735 are hinged to the end of the rotating arm 731. The ends of the ropes 734 are connected to the inner sides of the extension arms 735. The arm 735 is connected to a nozzle 736 installed at its outer end. The arm 731 has a conveying pipe 732 at its inner through hole. One end of the conveying pipe 732 is connected to a conveying pump, and the other end has a hemispherical head 7321. The arm 731 has a ball cavity 7314 that rotates with the hemispherical head 7321. The arm 731 has multiple liquid outlet connectors 7312 that connect with the ball cavity 7314 on its outer side. The liquid outlet connectors 7312 are connected to the nozzle 736 through pipes.

[0037] The pump inner side spraying mechanism 7 mainly solves the problems that existing equipment cannot automatically spray the inner side d of the water pump 8, which leads to low efficiency and poor quality due to reliance on manual labor, and that the irregular inner side d of the water pump 8 is difficult to achieve uniform coverage spraying. Through the centrifugal diameter change and movable rotation structure design, it realizes the automated, all-round and uniform spraying of the inner side d of the water pump 8.

[0038] Its working principle is as follows: The fixed platform 71 is set on the base 1. During the spraying operation, the motor 3 711 starts and drives the gear 5 712 to rotate. The gear 5 712 meshes with the gear 6 714 at the end of the threaded column 2 713, which drives the threaded column 2 713 to rotate. Since the threaded hole at the bottom of the moving platform 72 is adapted to the threaded column 2 713, the rotation of the threaded column 2 713 will drive the moving platform 72 to move laterally on the fixed platform 71, thereby driving the front end of the spraying arm 73 inside the pump to pass through the through hole inside the clamping plate 2 27 and extend into the water pump 8. Then the motor 4 721 starts, and the gear 722 at its output end and the rotating arm The gear 7311 at the rear end of 731 meshes and drives the rotating arm 731 to rotate. Multiple arms 735 hinged at the end of the rotating arm 731 open outward under the action of centrifugal force. The rope 734 connected to the inner side of the arms 735 pulls the rope wheel 733 to rotate. The vortex spring 737 on the rotating shaft on both sides of the rope wheel 733 is twisted and accumulates elastic potential energy. Through the balance between elastic potential energy and centrifugal force, the nozzle 736 is stabilized in a specific position. The centrifugal force can be changed by adjusting the speed of the motor 721, thereby adjusting the opening and closing angle of the arms 735 to adapt to the irregular shape of the inner side d of the water pump 8. During paint delivery, the delivery pump inside the base 1 delivers the paint to the delivery pipe 732 connected to the through hole inside the rotating arm 731. The hemispherical head 7321 at the end of the delivery pipe 732 rotates and engages with the ball cavity 7314 inside the rotating arm 731, ensuring that the paint delivery is not affected when the rotating arm 731 rotates. The paint is diverted through the ball cavity 7314 to multiple liquid outlet joints 7312 outside the rotating arm 731, and then delivered through the pipeline to the nozzle 736 at the outer end of the extension arm 735 and sprayed out. At the same time, the moving platform 72 can drive the spraying arm 73 inside the pump to move back and forth, which, together with the continuous rotation of the rotating arm 731, achieves comprehensive and uniform spraying of the inner surface d of the water pump 8.

[0039] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 9 and attached Figure 10As shown, the pump foot spraying mechanism 6 includes a cylinder 61, a transmission platform 62, a positioning platform 63, a rotating rod 64, and a nozzle 65. The cylinder 61 is installed at the bottom of the fixed beam 16 inside the spraying chamber 11. The output end of the cylinder 61 passes through a through hole on the fixed beam 16 and connects to the transmission platform 62. The bottom of the positioning platform 63 is provided with a positioning rod 631, which passes through the through holes on the transmission platform 62 and the fixed beam 16 in sequence. The bottom of the positioning platform 63 is provided with a spring 621 connected to the transmission platform 62. The rotating rod 64 is hinged to the positioning platform 65. The top of the platform 63 is connected by a torsion spring 632. The rear end of the rotating rod 64 is provided with a sliding groove 641. The top of the transmission platform 62 is provided with a vertical rod 622. The vertical rod 622 is provided with a sliding shaft 623 that slides with the sliding groove 641. The two ends of the rotating rod 64 are provided with mounting clips 642. The nozzle 65 is provided on the mounting clips 642. The positioning platform 63 is provided with a limiting frame 633. The limiting frame 633 is provided with an arc-shaped limiting groove 634. The inner side of the mounting clips 642 is provided with a limiting sliding rod 643 that slides with the limiting groove 634.

[0040] The pump foot spraying mechanism 6 mainly solves the problems of incomplete and uneven coating coverage of the pump foot c of the existing equipment, and the inability to achieve automatic special spraying. At the same time, it can repair and spray the two sides of the pump port. Through special structural design, the spraying quality and efficiency of the pump foot part are improved.

[0041] Its working principle is as follows: Cylinder 4 61 is installed at the bottom of the fixed beam 16 inside the spraying chamber 11. During the spraying operation, cylinder 4 61 is activated to push the transmission platform 62 connected to the output end to move upward. The transmission platform 62 drives the positioning platform 63 to move upward synchronously through the spring 2 621 connected to the bottom. The positioning rod 631 at the bottom of the positioning platform 63 passes through the through holes on the transmission platform 62 and the fixed beam 16 in sequence. When the bottom of the positioning rod 631 touches the fixed beam 16, the positioning platform 63 is blocked and stops moving upward. Cylinder 4 61 continues to push the transmission platform 62 to move upward. The spring 2 621 is compressed. The sliding shaft 623 on the top upright 622 of the transmission platform 62 moves upward relative to the positioning platform 63. The sliding shaft 623 slides and engages with the sliding groove 641 at the rear end of the rotating rod 64, thereby pushing the rotating rod 64, which is hinged to the top of the positioning platform 63, to rotate around the hinge point. The mounting clamp 2 642 at the two off-axis ends of the rotating rod 64 drives the nozzle 3 65 to rotate synchronously, forming a fan-shaped spraying trajectory to expand the spraying area.

[0042] The arc-shaped limiting groove 634 on the top limiting frame 633 of the positioning platform 63 slides with the limiting slide rod 643 inside the mounting clamp 642, limiting the rotation angle range of the nozzle 65 and avoiding excessive swinging that affects the spraying accuracy. The torsion spring 632 connected between the rotating rod 64 and the positioning platform 63 provides a restoring force when the transmission platform 62 moves down, driving the rotating rod 64 and the nozzle 65 back to the initial position. At the same time, the delivery pump in the base 1 delivers the paint to the nozzle 65. During the swinging process, the nozzle 65 sprays the outside of the pump foot c of the water pump 8 in a comprehensive and uniform manner, and can also perform repair spraying on both sides of the pump port.

[0043] Combined with appendix Figure 2 Appendix Figure 7 and attached Figure 8 As shown, the inner spraying mechanism 5 of the pump inlet includes a cylinder 51, a conveying platform 52, a sprayer 53, a fixed cylinder 54, and a pressure plate 55. The output end of the cylinder 51 is connected to the conveying platform 52. The sprayer 53 includes a connecting plate 531 and a drive shaft 532. The connecting plate 531 and the drive shaft 532 are rotatably coupled. The conveying platform 52 is connected to the connecting plate 531. A patterned platform 533 is provided on the outer side of the drive shaft 532. A patterned platform 533 is provided on the inner side of the fixed cylinder 54. 3. The grooves are matched and slide together. The front end of the fixed cylinder 54 is connected to the pressure plate 55, and the rear end is provided with a spring 56 connected to the connecting plate 531. The front end of the drive shaft 532 is provided with multiple nozzles 534. The nozzles 534 pass through the inner through holes of the fixed cylinder 54 and the pressure plate 55 and extend into the inner side of the pump port. The conveying platform 52 is provided with an external connector 521 and an internal connector 522 that are connected. The internal connector 522 is connected to the nozzles 534 through the inner through hole of the drive shaft 532.

[0044] The inner side spraying mechanism 5 of the pump inlet mainly solves the problems that existing equipment cannot automatically spray the inner side e of the pump inlet of the water pump 8, and that manual spraying is inefficient and the coating is uneven. Through the rotary advance and retreat spraying design, it realizes the automatic, all-round uniform spraying of the inner side e of the pump inlet.

[0045] Its working principle is as follows: The output end of cylinder 3 51 is connected to the conveyor platform 52. During the spraying operation, cylinder 3 51 starts and pushes the conveyor platform 52 forward, which in turn drives the sprayer 53 and the fixed cylinder 54 connected to it to move forward synchronously, so that the pressure plate 55 at the front end of the fixed cylinder 54 is tightly attached to the pump port of the water pump 8, realizing spraying positioning; cylinder 3 51 continues to push the conveyor platform 52 forward. Since the connecting plate 531 of the sprayer 53 is rotated and engaged with the drive shaft 532, and the patterned plate 533 on the outside of the drive shaft 532 matches and slides with the groove on the inside of the fixed cylinder 54, under the action of thrust, the patterned plate 533 slides along the groove, driving the drive shaft 532 to rotate and move forward at the same time. Multiple nozzles 534 rotate and extend into the inside of the pump port. When cylinder 51 drives the conveying platform 52 to move backward, spring 56 connected to the connecting plate 531 at the rear end of the fixed cylinder 54 releases its elastic potential energy, pushes the connecting plate 531 to reset, and drives the drive shaft 532 to rotate and move backward, ensuring that nozzles 534 can fully cover the inner side e of the pump port. During the paint conveying process, the conveying pump in the base 1 conveys the paint to the outer connector 521 on the conveying platform 52. The outer connector 521 is connected to the inner connector 522. The paint enters the through hole inside the drive shaft 532 through the inner connector 522 and is finally conveyed to nozzles 534 and sprayed out evenly, completing the automated and uniform spraying of the inner side e of the pump port.

[0046] Combined with appendix Figure 2 Appendix Figure 4 and attached Figure 5 As shown, the clamping mechanism 2 is provided with positioning mechanisms 3 on both sides. The positioning mechanism 3 includes a positioning seat 31. The positioning seat 31 is provided with a cylinder 32 and a pusher 33. The cylinder 32 drives the pusher 33 to slide back and forth on the positioning seat 31. Two support plates 34 are symmetrically provided on the pusher 33. The support plates 34 slide left and right on the pusher 33. The front end of the support plate 34 is provided with a support groove 341. The outer side of the support plate 34 is provided with a second inclined platform 342. The positioning seat 31 is provided with an inclined platform 311 that slides with the second inclined platform 342.

[0047] The positioning mechanism 3 primarily addresses the problem of inaccurate positioning of the water pump 8 after it is placed in the spray chamber 11, which makes it difficult for the clamping mechanism 2 to accurately clamp the flanges on both sides of the water pump 8, affecting the stability of subsequent spraying operations. Through an automatic positioning function, the water pump 8 is quickly aligned with the clamping position, facilitating efficient and precise clamping by the clamping mechanism 2. Its working principle is as follows: The positioning seat 31 is fixed inside the spray chamber 11. To ensure accurate alignment of the flanges on both sides of the water pump 8 with the clamping plates 26 and 27 of the clamping mechanism 2, before the water pump 8 is placed in the spray chamber 11, cylinder 32 is activated, driving the pusher 33 to slide forward on the positioning seat 31. The two symmetrically arranged support plates 34 on the pusher 33 move to the preset appropriate positions. Then, the pump feet of the water pump 8 are placed on the grooves 341 at the front of the two support plates 34. Next, cylinder 32... As the pusher 33 continues to move forward, the inclined platform 342 on the outer side of the support plate 34 slides and is squeezed by the inclined platform 311 on the positioning seat 31, forcing the two support plates 34 to slide towards the middle on the pusher 33. The pump foot of the water pump 8 is tightly clamped by the groove 341, so that the water pump 8 is kept in a stable and accurate position in the spraying chamber 11. After the clamping mechanism 2 firmly clamps the water pump 8, the cylinder 32 drives the pusher 33 to slide backward and reset, so as to avoid interfering with the subsequent spraying operation.

[0048] Combined with appendix Figure 2 and attached Figure 6 As shown, the pump outer spraying mechanism 4 includes a second cylinder 41. The output end of the second cylinder 41 is provided with a slider 42. The slider 42 is slidably disposed in the spraying chamber 11. Multiple deformation frames 43 are provided on the slider 42. The deformation frames 43 can be bent. A mounting clip 44 is sleeved on the deformation frame 43. A spray head 45 is provided on the mounting clip 44.

[0049] The pump outer spraying mechanism 4 mainly solves the problems of uneven and incomplete spraying of the outer surface a and flange back surface of the water pump 8 by existing equipment, and the difficulty in adapting to water pumps 8 with different shapes to achieve automatic special spraying. Through the adjustable structure design, it can achieve accurate and uniform automatic spraying of the regular outer surface a and flange back surface of the water pump 8, thereby improving the spraying quality and adaptability.

[0050] Its working principle is as follows: Before operation, according to the outline of the water pump 8, the angles of multiple bendable deformation frames 43 on the slider 42 are adjusted, and the position of the mounting clip 44 on the deformation frame 43 is moved so that the nozzle 45 on the mounting clip 44 is precisely aligned with the area to be sprayed on the outer side a and the flange back of the water pump 8; after the water pump 8 is firmly clamped by the clamping mechanism 2, the cylinder 41 is activated to push the slider 42 connected to the output end to slide forward in the spray chamber 11, bringing the nozzle 45 closer to the water pump 8. At the same time, the clamping mechanism 2 drives the water pump 8 to rotate continuously, and the delivery pump in the base 1 delivers the paint to the nozzle 45 and sprays it out. The rotation of the water pump 8 achieves uniform spraying on the regular outer side a and the flange back; when passing the pump port flange and pump foot position during the spraying process, the cylinder 41 drives the slider 42 to move back appropriately to avoid the nozzle 45 from colliding with these parts, ensuring that the spraying operation is carried out safely and smoothly.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
