[0004] However, existing painting equipment still has some shortcomings when painting columnar mechanical parts:

When it is necessary to flip the columnar mechanical parts, the operator has to manually flip them after the painting equipment is stopped. Since the painting process requires stopping the machine and manual operation, it will have a certain impact on the painting efficiency of columnar mechanical parts and make the manual labor intensity of the painting process high.

The arc-shaped clamping plates 34 cause the spring rod 36 to retract, and the support ring 33 can support the other end of the columnar mechanical component, thereby achieving the clamping of the columnar mechanical component before painting. When the end of the columnar mechanical component enters the interior of the second sleeve 32, the columnar mechanical component being pushed horizontally can separate from the two inclined clamping plates 35, and the end of the columnar mechanical component enters between the two arc-shaped clamping plates 34. The extension of the spring rod 36 can clamp the end of the columnar mechanical component through the arc-shaped clamping plates 34, thereby achieving the clamping of the columnar mechanical component during the painting process.

[0036] The pushing mechanism 4 includes two first rotating shafts 41.

A passive transmission wheel 431 is fixedly installed on one end of each of the two first rotating shafts 41. A toothed belt 432 is installed between the transmissions. By driving the first rotating shaft 41 to rotate, the first rotating shaft 41 can transmit the conveyor belt 43 through the rotating roller 42. The conveyor belt 43 can pass through the first sleeve 31 and the support ring 33 to allow the unpainted columnar mechanical parts to pass through the feed chute 11 and enter the paint spraying chamber 1. At the same time, the conveyor belt 43 can pass through the first sleeve 31 and the support ring 33 to allow the columnar mechanical parts in the painting process to pass through the discharge chute 12 and separate from the paint spraying chamber 1, and enter the second sleeve 32. The toothed belt 432 can transmit the parts through the drive of the toothed belt 432. The toothed belt 432 can drive the two first rotating shafts 41 to rotate through the two passive transmission wheels 431.

It drives the second transmission belt 5 for transmission. When the second teeth 51 mesh with the toothed belt 432, the second teeth 51 drive the toothed belt 432 to transmit in the reverse direction, thereby realizing the reverse transmission of the conveyor belt 43. The forward and reverse transmission of the conveyor belt 43 realizes the reciprocating pushing of the columnar mechanical parts. When the columnar mechanical parts in the paint spraying chamber 1 are separated from the paint spraying chamber 1 through the feed chute 11, there is no other action at this time, allowing the operators to observe the painting process of the columnar mechanical parts.

By driving the rotating shaft 62 to rotate back and forth, the rotating shaft 62 can make the spray head 63 swing back and forth around the axis of the rotating shaft 62. During the reciprocating swing operation, the spray head 63 evenly sprays the paint onto the columnar mechanical parts.

[0040] A third rotating rod 65 is rotatably mounted on the side of the paint spraying tank 1 near the feed trough 11. A first sector gear 66 is fixedly mounted on one end of the third rotating rod 65. A driven gear 67 is fixedly mounted on the end of one of the rotating shafts 62 away from the nozzle 63.

A third bevel gear 92 is fixedly mounted on one end of the fifth transmission rod 9 and one end of one of the second rotating shafts 82. The three bevel gears 92 mesh with each other. When the first tooth 47 disengages from the toothed belt 432, the conveyor belt 43 stops transmitting. The end of the cylindrical mechanical part enters the second sleeve 32 and is clamped, and stops moving horizontally. As the first transmission belt 46 continues to transmit, when the first tooth 47 meshes with the drive gear 86, the first tooth 47 can make the drive gear 86 rotate. The drive gear 86 makes the third transmission rod 85 rotate. The third transmission rod 85 can make the fourth transmission rod 87 rotate through the two fourth synchronous pulleys 88 and the fourth synchronous belt 89.

The fifth transmission rod 9 can make a second rotating shaft 82 rotate through the two third bevel gears 92.

[0044] Working principle: When it is necessary to spray paint columnar mechanical parts, the operator first inserts one end of the columnar mechanical part to be painted into the corresponding first sleeve 31. During this process, the horizontal extrusion force of the end of the columnar mechanical part entering the first sleeve 31 causes the two inclined clamping plates 35 to move away from each other. The two inclined clamping plates 35 cause the two arc-shaped clamping plates 34 to move away from each other and squeeze the spring rod 36, causing the spring rod 36 to retract. When the end of the columnar mechanical part is completely inside the first sleeve 31, the spring rod 36 retracts and clamps the end of the columnar mechanical part through the two arc-shaped clamping plates 34. At this time, the other end of the columnar mechanical part contacts the inner wall of the support ring 33.

[0045] Subsequently, the operator simultaneously turns on the servo motor 54 and the nozzle 63. The drive shaft of the servo motor 54 causes the corresponding second rotating rod 48 to rotate. The two second rotating rods 48 transmit power through the two second transmission wheels 49 via the second transmission belt 5. The second transmission belt 5 causes multiple second teeth 51 to move horizontally toward one side of the paint spraying chamber 1. At the same time, one second rotating rod 48 causes the corresponding first rotating rod 44 to rotate through the two first synchronous pulleys 52 and the first synchronous belt 53. The two first rotating rods 44 cause multiple first teeth 47 to move horizontally toward one side of the paint spraying chamber 1 via the two first transmission wheels 45 and the first transmission belt 46. The multiple first teeth 47 cause two first rotating shafts 41 to rotate through the toothed belt 432 and the two passive transmission wheels 431. The two first rotating shafts 41 transmit power through the two rotating rollers 42 via the conveyor belt 43 toward one side of the paint spraying chamber 1. The conveyor belt 43 transmits power through the first sleeve 31 and the support ring 33 to allow the columnar mechanical parts to pass through the feed chute 11 and enter the paint spraying chamber 1.

[0046] Simultaneously, a second rotating rod 48 rotates the first transmission rod 7 via two second synchronous pulleys 71 and a second synchronous belt 72. The first transmission rod 7 rotates the second transmission rod 73 via two first bevel gears 74. The second transmission rod 73 rotates the third rotating rod 65 in a synchronous and opposite direction to the second transmission rod 73 via two transmission gears 75. The third rotating rod 65 drives the driven gear 67 to rotate in the forward direction via a first sector gear 66. At the same time, the second transmission rod 73 rotates the fourth rotating rod 68 in a synchronous and same direction as the second transmission rod 73 via two third synchronous pulleys 76 and a third synchronous belt 77. The fourth rotating rod 68 rotates the second sector gear 69. At this time, the first sector gear... The first sector gear 66 and the second sector gear 69 rotate synchronously in opposite directions. When the first sector gear 66 disengages from the driven gear 67, the second sector gear 69 meshes with the driven gear 67 and drives the driven gear 67 to rotate. At this time, as the first sector gear 66 and the second sector gear 69 engage in a staggered engagement, the driven gear 67 rotates back and forth. The driven gear 67 causes the spray head 63 to oscillate back and forth around the axis of the shaft 62 via the rotating shaft 62. During the reciprocating oscillation, the spray head 63 evenly sprays the paint onto the outer wall of the columnar mechanical parts, thus facilitating the reciprocating painting of the columnar mechanical parts and effectively improving the painting effect of the columnar mechanical parts.

[0047] After the conveyor belt 43 causes the columnar mechanical part to pass through the discharge chute 12 and separate from the paint spraying chamber 1, the other end of the columnar mechanical part enters the second sleeve 32. The extrusion force of the horizontal conveying causes the other end of the columnar mechanical part to enter between the two arc-shaped clamping plates 34 inside the second sleeve 32. The two arc-shaped clamping plates 34 clamp the other end of the columnar mechanical part. At the same time, multiple first teeth 47 disengage from the toothed belt 432, the conveyor belt 43 stops conveying, and the columnar mechanical part is in a stationary state.

[0048] As the first transmission belt 46 continues to transmit, when multiple first teeth 47 mesh with the drive gear 86, the multiple first teeth 47 cause the drive gear 86 to rotate, the drive gear 86 causes the third transmission rod 85 to rotate, the third transmission rod 85 causes the fourth transmission rod 87 to rotate through two fourth synchronous pulleys 88 and a fourth synchronous belt 89, the fourth transmission rod 87 causes the fifth transmission rod 9 to rotate through two second bevel gears 91, the fifth transmission rod 9 causes a corresponding second rotating shaft 82 to rotate through two third bevel gears 92, the second rotating shaft 82 causes multiple second rotating shafts 82 to rotate synchronously and in the same direction through multiple sprockets 83 and chains 84, the multiple second rotating shafts 82 cause the columnar mechanical parts to flip over, so that the unpainted parts of the columnar mechanical parts face upwards;

[0049] When multiple first teeth 47 disengage from the drive gear 86, the cylindrical mechanical part stops rotating. Multiple second teeth 51 mesh with the toothed belt 432 and drive the toothed belt 432 to reverse transmission. At this time, the conveyor belt 43 reverses transmission and separates the cylindrical mechanical part from the second sleeve 32 through the first sleeve 31. It then re-enters the paint spraying chamber 1 through the discharge chute 12. The spray nozzle 63 reciprocates to spray paint the unpainted parts of the cylindrical mechanical part, thus conveniently realizing the reciprocating horizontal movement and automatic rotation of the cylindrical mechanical part. This effectively improves the efficiency of the painting process of the cylindrical mechanical part and reduces the manual labor intensity during the painting process.

[0050] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
