Description

Technical Field

[0001] The present invention relates to the technical field of spray painting, and particularly to an efficient spray painting device for circular tubular parts. Background Art

[0002] During the processing of workpieces, surface spray painting treatment is required to extend the lifespan of the workpieces and achieve special properties such as heat insulation and fire prevention.

[0003] Currently, the main spray painting methods are manual spray painting and mechanical spray painting. During manual spray painting, the splashing paint liquid can cause great harm to the workers' bodies. When using mechanical equipment for spray painting, the moving speed of the spray head cannot be automatically adjusted according to the diameter of the pipe fittings. When the diameter of the pipe fitting is small, it may lead to too much paint spraying, wasting resources. When the diameter of the pipe fitting is large, it may lead to uneven paint spraying, affecting the performance of the pipe fitting. Moreover, after spray painting, the pipe fittings need to be manually taken out, and the paint liquid remaining on the pipe fittings overflowing outward will affect the physical health of the workers.

Detailed implementation manners

[0020] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.

[0021] Embodiment 1: An efficient painting device for circular tubular components, as Figures 1 - 15As shown in the figure, it includes a workbench 1, a U-shaped rod 101, a rotating table 102, a connecting shaft 103, a control motor 104, a fixed bracket 105, a first belt transmission 106, a moving rod 4, a spray head 401, a vertical guide rod 402, a reciprocating screw rod 403, a clamping mechanism and a lifting mechanism. A U-shaped rod 101 is fixedly connected to the workbench 1, and the U-shaped rod 101 plays a supporting role. A rotating table 102 is rotatably arranged on the workbench 1, and a pipe fitting to be painted can be placed on the rotating table 102. A connecting shaft 103 is fixedly connected to the rotating table 102. A control motor 104 is installed inside the workbench 1. There is a first belt transmission 106 between the output shaft of the control motor 104 and the connecting shaft 103. The control motor 104 can drive the connecting shaft 103 to rotate through the first belt transmission 106, thereby driving the rotating table 102 and the pipe fitting on its top to rotate. A fixed bracket 105 is fixedly connected to the U-shaped rod 101. A vertical guide rod 402 is fixedly connected to the workbench 1. A reciprocating screw rod 403 is rotatably connected to the workbench 1. One end of the moving rod 4 is slidably connected to the vertical guide rod 402, and the other end of the moving rod 4 is threadedly connected to the reciprocating screw rod 403. When the reciprocating screw rod 403 rotates, the moving rod 4 will slide up and down along the vertical guide rod 402. A spray head 401 is installed on the moving rod 4. The spray head 401 is located above the rotating table 102. The spray head 401 is connected to an external paint bucket. When the moving rod 4 moves up and down, the spray head 401 will spray paint on the inner wall of the pipe fitting. The clamping mechanism is installed on the connecting shaft 103 and the rotating table 102, and the clamping mechanism can clamp the pipe fitting on the rotating table 102. The lifting mechanism is installed on the workbench 1, and the lifting mechanism can drive the reciprocating screw rod 403 to rotate, so that the moving rod 4 moves up and down.

[0022] Place the pipe fitting on the rotating table 102, then clamp the pipe fitting through the clamping mechanism, and then start the control motor 104. The control motor 104 can drive the connecting shaft 103 to rotate through the first belt transmission 106, and the rotating table 102 will also rotate accordingly. The clamping mechanism clamps the pipe fitting and rotates with the rotating table 102. After the control motor 104 is started, it can also drive the lifting mechanism to operate. The lifting mechanism can drive the reciprocating screw rod 403 to rotate, so that the moving rod 4 can drive the spray head 401 to move up and down along the vertical guide rod 402. When the moving rod 4 drives the spray head 401 to descend, it can spray paint into the pipe fitting. After the painting is completed and the moving rod 4 drives the spray head 401 to rise and reset, first turn off the control motor 104 and make the clamping mechanism loosen the pipe fitting, and then remove the painted pipe fitting, realizing the function of quickly spraying paint on the inner wall of the pipe fitting.

[0023] Embodiment 2: On the basis of Embodiment 1, as Figure 3 and Figure 6As shown, the clamping mechanism includes a sliding disk 3, connecting columns 3001, a downward pressure spring 301, a lifting block 302, an arc-shaped clamping rod 303, a rotating clamping rod 304, a release spring 305 and a control component.

A downward pressure spring 301 is provided between the connecting columns 3001 and the lifting block 302. When the sliding disk 3 slides downward along the connecting shaft 103, the lifting block 302 can be driven to descend through the connecting columns 3001 and the downward pressure spring 301. An arc-shaped clamping rod 303 is slidably connected to the rotating table 102. The arc-shaped clamping rod 303 can clamp the pipe fitting. A release spring 305 is provided between the arc-shaped clamping rod 303 and the rotating table 102. The release spring 305 can push the arc-shaped clamping rod 303 to slide back along the rotating table 102 and release the pipe fitting. One end of the rotating clamping rod 304 is rotatably connected to the lifting block 302, and the other end of the rotating clamping rod 304 is rotatably connected to the arc-shaped clamping rod 303. When the lifting block 302 descends, the arc-shaped clamping rod 303 can be pulled to clamp the pipe fitting through the rotating clamping rod 304. The control component is installed on the workbench 1. The control component can drive the sliding disk 3 to slide along the connecting shaft 103.

[0024] After placing the pipe fitting on the rotating table 102, start the control component. The control component can push the sliding disk 3 to slide downward along the connecting shaft 103. When the sliding disk 3 descends, the connecting columns 3001 also descend therewith. And when the connecting columns 3001 descend, the lifting block 302 can be pushed to descend along the connecting shaft 103 through the downward pressure spring 301. When the lifting block 302 descends, it will pull the arc-shaped clamping rods 303 to approach each other and compress the release spring 305 through the rotating clamping rod 304. The arc-shaped clamping rods 303 approaching each other will clamp the pipe fitting on the rotating table 102. Subsequently, the rotating table 102 can drive the pipe fitting to rotate. After the interior of the pipe fitting is painted, the control component moves back to its original position. At this time, under the push of the release spring 305, the arc-shaped clamping rods 303 will move away from each other. At the same time, the lifting block 302 is pulled to rise through the rotating clamping rod 304. When the lifting block 302 rises, it will push the connecting columns 3001 and the sliding disk 3 to rise back to their original positions, realizing the function of clamping the pipe fitting.

[0025] As Figure 3 and Figure 6As shown in the figure, the control component includes a pusher cylinder 201, a sliding pusher block 202, an L-shaped push rod 203, a sliding frame 204, a moving pressure frame 2041 and a return spring 205. The pusher cylinder 201 is installed on the workbench 1. The sliding pusher block 202 is slidably connected to the workbench 1. The pusher cylinder 201 can push the sliding pusher block 202 to slide along the workbench 1. The L-shaped push rod 203 is fixedly connected to the sliding pusher block 202. The sliding frame 204 is slidably connected to the U-shaped rod 101. The L-shaped push rod 203 passes through the sliding frame 204 and is slidably connected to it. A return spring 205 is provided between the L-shaped push rod 203 and the sliding frame 204. The L-shaped push rod 203 can drive the sliding frame 204 to move through the return spring 205. The moving pressure frame 2041 is fixedly connected to the sliding frame 204. The moving pressure frame 2041 can push the sliding disk 3 to slide downward along the connecting shaft 103.

[0026] After the pipe fitting is placed on the rotating table 102, start the pusher cylinder 201. The pusher cylinder 201 can pull the sliding pusher block 202 to slide along the workbench 1 in a direction away from the rotating disk. When the sliding pusher block 202 moves, it will pull the sliding frame 204 to move towards the connecting shaft 103 and compress the return spring 205 through the L-shaped push rod 203. When the sliding frame 204 moves, it pushes the sliding disk 3 to descend along the connecting shaft 103 through the moving pressure frame 2041. After the pipe fitting is painted, control the pusher cylinder 201 to push the sliding pusher block 202 to move along the workbench 1 in a direction close to the rotating disk. Under the push of the return spring 205, the sliding frame 204 and the moving pressure frame 2041 slide in a direction away from the connecting shaft 103, and the sliding disk 3 moves back to its original position, realizing the function of pushing the sliding disk 3 to move.

[0027] As Figures 9 - 11As shown in the figure, the lifting mechanism includes a first bevel gear 404, a second bevel gear 405, a second belt transmission member 406, a pulley 407, a rotating frame 408, an adjusting wheel 409, a variable-diameter wheel 411, a transmission shaft 4111, a tensioning wheel 412, a tensioning spring 413, a transmission belt 414, a third bevel gear 415, and a fourth bevel gear 416. A first bevel gear 404 is rotatably connected to the workbench 1. A second belt transmission member 406 is provided between the control motor 104 and the first bevel gear 404. The control motor 104 can drive the first bevel gear 404 to rotate through the second belt transmission member 406. A pulley 407 is rotatably connected to the workbench 1. A second bevel gear 405 is coaxially and fixedly connected to the pulley 407. The first bevel gear 404 and the second bevel gear 405 are meshed. The first bevel gear 404 can drive the pulley 407 to rotate through the second bevel gear 405. A rotating frame 408 is rotatably connected to the workbench 1. An adjusting wheel 409 is rotatably connected to the rotating frame 408. A transmission shaft 4111 is rotatably connected to the fixed bracket 105. A variable-diameter wheel 411 is slidably connected to the transmission shaft 4111. A tensioning wheel 412 is slidably connected to the U-shaped rod 101. A tensioning spring 413 is provided between the tensioning wheel 412 and the U-shaped rod 101. A transmission belt 414 is wound around the pulley 407, the adjusting wheel 409, the variable-diameter wheel 411, and the tensioning wheel 412. The pulley 407 can drive the adjusting wheel 409, the variable-diameter wheel 411, and the tensioning wheel 412 to rotate through the transmission belt 414. A third bevel gear 415 is fixedly connected to the transmission shaft 4111. The variable-diameter wheel 411 can drive the third bevel gear 415 to rotate through the transmission shaft 4111. A fourth bevel gear 416 is fixedly connected to the reciprocating screw rod 403. The third bevel gear 415 and the fourth bevel gear 416 are meshed. The third bevel gear 415 can drive the reciprocating screw rod 403 to rotate through the fourth bevel gear 416.

[0028] After the control motor 104 is started, it will drive the first bevel gear 404 to rotate through the second belt transmission member 406. The first bevel gear 404 drives the pulley 407 to rotate through the second bevel gear 405. When the pulley 407 rotates, it can drive the adjusting wheel 409, the variable-diameter wheel 411, and the tensioning wheel 412 to rotate through the transmission belt 414. When the variable-diameter wheel 411 rotates, it will drive the third bevel gear 415 to rotate through the transmission shaft 4111. When the third bevel gear 415 rotates, it can drive the reciprocating screw rod 403 to rotate through the fourth bevel gear 416, so as to drive the moving rod 4 and the nozzle 401 to move, realizing the function of controlling the lifting of the moving rod 4 and the nozzle 401.

[0029] Embodiment 3: On the basis of Embodiment 2, as Figures 8 - 11 and Figure 13As shown, it also includes a sliding adjustment frame 5, a reset spring 501, an arc-shaped push plate 505, a connecting spring 506 and a pull rope 507. The sliding adjustment frame 5 is slidably connected to the workbench 1. A reset spring 501 is provided between the sliding adjustment frame 5 and the workbench 1. The reset spring 501 can push the sliding adjustment frame 5 to slide and reset along the workbench 1. The sliding adjustment frame 5 is connected to the variable diameter wheel 411. When the sliding adjustment frame 5 moves, it can push the variable diameter wheel 411 to slide along the transmission shaft 4111. The rotating table 102 is movable, and an arc-shaped push plate 505 is slidably connected to the rotating table 102. A connecting spring 506 is provided between the arc-shaped push plate 505 and the rotating table 102. When the rotating table 102 rotates, the arc-shaped push plate 505 is subjected to centrifugal force and slides outward along the rotating table 102 and pushes the sliding position adjustment frame 5 to move. A pull rope 507 is provided between the lifting block 302 and the arc-shaped push plate 505. The lifting block 302 limits the distance that the arc-shaped push plate 505 slides outward under the centrifugal force through the pull rope 507.

[0030] When the rotary table 102 rotates, the arc push plate 505 slides outward from the rotary table 102 due to the centrifugal force, and because the rotation speed of the rotary table 102 is suddenly increased, the arc push plate 505 contacts the sliding adjustment frame 5 when sliding outward and pushes it to slide in the direction away from the rotary table 102, and at the same time compresses the return spring 501. When the sliding adjustment frame 5 moves, it can drive the reducing wheel 411 to slide along the transmission shaft 4111. The reducing wheel 411 is provided with slots of different diameters. When the reducing wheel 411 moves away from the rotary table 102, the transmission belt 414 will wrap around the slot with a larger diameter on the reducing wheel 411. The larger the diameter of the pipe to be painted, the farther the distance between the two arc clamping rods 303 is, and the sliding disc 3 and the lifting block 302 are connected along the shaft. The smaller the distance the connecting shaft 103 descends, the less the lifting block 302 descends, and the longer the distance the arc-shaped push plate 505 slides outward along the rotating table 102, because the arc-shaped push plate 505 is connected to the lifting block 302 by the pull rope 507, so that the transmission belt 414 can be wound around the groove with a larger diameter on the reducing wheel 411. The tensioning wheel 412 also moves and compresses the tensioning spring 413, so that the rotation speed of the reducing wheel 411 slows down, and the rotation speeds of the third bevel gear 415, the fourth bevel gear 416 and the reciprocating screw 403 also slow down, so as to reduce the speed of the moving rod 4 and the spray head 401 moving up and down, so as to ensure that the paint is evenly sprayed on the inner wall of the pipe fitting, thereby realizing the function of adjusting the movement speed of the moving rod 4 and the spray head 401 according to the diameter of the pipe fitting.

[0031] like Figure 12As shown, it also includes a torsion spring 410, a sliding tooth plate 502, a return spring 503 and a rotating plate 504. A torsion spring 410 is provided between the rotating frame 408 and the workbench 1. The sliding tooth plate 502 is slidably connected to the workbench 1. The sliding adjustment frame 5 is in sliding contact with the sliding tooth plate 502. When the sliding adjustment frame 5 slides along the workbench 1, it can push the sliding tooth plate 502 to move. A return spring 503 is provided between the sliding tooth plate 502 and the workbench 1. The return spring 503 can push the sliding tooth plate 502 to slide back and forth. The workbench 1 is in the position, and a rotating plate 504 is rotatably connected to the workbench 1. Both ends of the rotating plate 504 are provided with a slotted hole. The sliding tooth plate 502 is connected to the slotted hole at one end of the rotating plate 504. When the sliding tooth plate 502 slides, it can drive the rotating plate 504 to rotate on the workbench 1. The top of the rotating frame 408 passes through the slotted hole at the other end of the rotating plate 504, and in the normal state, the rotating frame 408 does not contact the inner wall of the slotted hole on the rotating plate 504. When the rotating plate 504 rotates, it can drive the rotating frame 408 to swing.

[0032] When the sliding adjustment frame 5 moves, it pushes the sliding tooth plate 502 to move and compresses the return spring 503. When the sliding adjustment frame 5 moves past the teeth on the sliding tooth plate 502, the return spring 503 pushes the sliding tooth plate 502 to move and reset and jam the sliding adjustment frame 5 to prevent the sliding adjustment frame 5 from automatically resetting and causing the device to jam. In the process of the sliding tooth plate 502 moving and compressing the return spring 503, the rotating frame 408 is driven to rotate through the rotating plate 504, and the torsion spring 410 is deformed by the force. When the rotating frame 408 rotates, it can The transmission belt 414 is lifted upward by the adjusting wheel 409, and at the same time, the tensioning wheel 412 is driven to move and compress the tensioning spring 413. The adjusting wheel 409 lifts the transmission belt 414 upward to prevent the variable diameter wheel 411 from being blocked, and when the return spring 503 pushes the sliding tooth plate 502 to slide and reset, the rotating frame 408 rotates and resets, and the adjusting wheel 409 can also put the transmission belt 414 into the corresponding slot on the variable diameter wheel 411, thereby cooperating with the sliding position adjustment frame 5 to adjust the position of the transmission belt 414 on the variable diameter wheel 411.

[0033] like Figure 2 and Figure 4 As shown, it also includes a material storage box 2, a sliding material baffle plate 2001 and a material baffle spring 2002. A material storage box 2 is installed on the workbench 1, and the material storage box 2 stores pipes to be painted. A sliding material baffle plate 2001 is slidably connected to the material storage box 2. The sliding material baffle plate 2001 is inclined at one end facing the pipe, so that the sliding material baffle plate 2001 can be inserted between the two pipes. A material baffle spring 2002 is provided between the sliding material baffle plate 2001 and the material storage box 2. The material baffle spring 2002 can push the sliding material baffle plate 2001 to slide into the material storage box 2 and prevent the pipe from falling. When the sliding push block 202 slides and resets along the workbench 1, the sliding material baffle plate 2001 can be pushed out of the material storage box 2.

[0034] Before painting the pipe fittings, place the pipe fittings into the storage bin 2. When the pushing cylinder 201 pulls the sliding pushing block 202 to move in a direction away from the rotating table 102, the sliding pushing block 202 can push the sliding baffle 2001 out of the storage bin 2 and compress the baffle spring 2002. After the sliding baffle 2001 completely slides out of the storage bin 2, the pipe fittings in the storage bin 2 will slide down to the workbench 1. When the pushing cylinder 201 pushes the sliding pushing block 202 to slide along the workbench 1 in a direction close to the rotating table 102, the sliding pushing block 202 will push the pipe fittings towards the rotating table 102. At this time, the baffle spring 2002 will push the sliding baffle 2001 to slide into the storage bin 2, and the sliding baffle 2001 will block below the pipe fittings at the bottom of the storage bin 2 to prevent the pipe fittings in the storage bin 2 from continuing to fall, thus realizing the function of automatically pushing the pipe fittings onto the rotating table 102.

[0035] As Figure 4 and Figure 5 shown, it further includes a sliding limiting rod 2021 and a buffer spring 2022. The sliding limiting rod 2021 is slidably connected to the sliding pushing block 202, and a buffer spring 2022 is provided between the sliding limiting rod 2021 and the sliding pushing block 202. The sliding pushing block 202 can drive the sliding limiting rod 2021 to move.

[0036] After the pipe fittings on the rotating table 102 are painted, turn off the control motor 104. At this time, the rotating table 102 continues to rotate under the action of inertia. When the sliding pushing block 202 pushes the pipe fittings, the sliding limiting rod 2021 will move accordingly. When the front end of the sliding limiting rod 2021 contacts the arc-shaped clamping rod 303, it can stop the rotation of the rotating table 102. Subsequently, the sliding pushing block 202 continues to push the pipe fittings to be painted to move. At this time, the buffer spring 2022 is compressed and the sliding limiting rod 2021 no longer moves. The sliding pushing block 202 can push the painted pipe fittings out of the rotating table 102 through the pipe fittings to be painted, thus realizing the function of automatically pushing the painted pipe fittings on the rotating table 102 outwards.

[0037] As Figure 14 and Figure 15 shown, it further includes a fixing plate 508, a sliding push rod 509 and a wedge block 5091. The fixing plate 508 is fixedly connected to the sliding tooth plate 502. The sliding push rod 509 is slidably connected to the U-shaped rod 101. The sliding push rod 509 contacts the fixing plate 508. The sliding push rod 509 can drive the sliding tooth plate 502 to slide along the workbench 1 through the fixing plate 508. The wedge block 5091 is fixedly connected to the sliding push rod 509. The sliding frame 204 can push the sliding push rod 509 to slide along the U-shaped rod 101 through the wedge block 5091.

[0038] When the pushing cylinder 201 pushes the sliding pushing block 202 to move in the direction close to the rotating table 102, the sliding frame 204 will move toward the wedge block 5091 under the push of the return spring 205. When the sliding frame 204 contacts the wedge block 5091, the sliding frame 204 can push the sliding push rod 509 to slide along the U-shaped rod 101 through the wedge block 5091. When the sliding push rod 509 moves, it will drive the sliding tooth plate 502 to slide along the workbench 1 through the fixed plate 508 and compress the return spring 503. At this time, the teeth on the sliding tooth plate 502 no longer restrict the sliding positioning frame 5. Under the push of the return spring 501, the sliding positioning frame 5 can move and reset, thereby realizing the function of automatically resetting the sliding positioning frame 5.

[0039] like Figure 7 As shown, a rubber strip is installed in the arc-shaped clamping rod 303 to increase the friction force on the pipe fitting, which can play an anti-slip effect; the arc-shaped clamping rod 303 clamps the pipe fitting through the rubber strip, and the friction force between the rubber strip and the pipe fitting is large enough to ensure that the pipe fitting will not slip during the process of the rotating table 102 driving the pipe fitting to rotate.
