Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power distribution cabinet paint spraying, and particularly relates to a full-automatic paint spraying conveying device for a high-low voltage power distribution cabinet body. BACKGROUND

[0002] The high-low voltage power distribution cabinet is a power distribution device used for power distribution, control, metering and cable connection in a power supply system. The device is composed of switches, circuit breakers, fuses, buttons, indicator lights, instruments and wires, and achieves the design function requirement of the power distribution device. In order to prevent the power distribution cabinet from rusting, paint spraying is required during the manufacturing process of the power distribution cabinet.

[0003] In the existing paint spraying process, a control cabinet automatic paint spraying device is disclosed in Chinese Patent No. CN111701777A. The device includes a workbench, a support cabinet body installed below the workbench through bolts, a through opening formed on the surface of the support cabinet body, a fixed base installed at the bottom of the support cabinet body through bolts, a paint placing barrel placed on the surface of the fixed base, a through pipe inserted into the paint placing barrel, a pressure pump installed at the other end of the through pipe through threads, a pressure pump installed below the workbench through threads, a flexible pipe installed above the pressure pump through threads, and the flexible pipe penetrating through the workbench. A spraying frame is connected to the other end of the flexible pipe through threads, and a sliding plate is connected to the outer side of the spraying frame through fixing bolts. The device solves the problems of low automation degree, small range of use, and easy absorption of paint by setting the spraying frame, the sliding sleeve and the dust collection equipment.

[0004] In the above-mentioned prior art, the cabinet body is painted by using the spraying frame, and the automation degree of paint spraying is improved. However, the above-mentioned prior art does not consider the uneven spraying of the internal corners and hoisting positions of the cabinet body during the paint spraying process. Due to the narrow space of the corner area, it is difficult to uniformly spray the corner area by relying on large-area spraying when the spray head is not aligned. In addition, the hoisting point does not change during the entire paint spraying process of the prior art, so that the position contacted by the hoisting point is difficult to be sprayed by paint, causing local missed spraying. The uneven spraying or missed spraying easily accelerates the formation of rust, thereby sharply shortening the service life of the cabinet body. Therefore, there is still room for improvement in the existing paint spraying technology. SUMMARY

The inside of the second spray head 551 is sequentially provided with the second connecting hole 553 and the third connecting hole 554 from top to bottom. When the lifting and extruding assembly 58 is lowered, the second spray head 551 is rotated to make the second connecting hole 553 align with the material conveying hole 61. At this time, the second spray head 551 aligns with the original lifting position (the lifting rod 441 has been removed from the original lifting position, and at this time, the original lifting position is a blank surface without painting), so as to paint the blank surface of the original lifting position. The blank surface of the original lifting position is small, and the aperture of the second connecting hole 553 is smaller than the aperture of the third connecting hole 554. When the second connecting hole 553 aligns with the material conveying hole 61, the spray flow is reduced, and the original lifting position is precisely painted. The paint spray box 51 is provided with a material conveying hole 61 at the corresponding position. The paint spray box 51 and the second spray head 551 are connected with the spring 552. When the lifting and extruding assembly 58 is raised, the second spray head 551 is restored to the initial position through the driving of the spring 552. When the second spray head 551 is in the initial position, the third connecting hole 554 aligns and communicates with the material conveying hole 61. The second spray head 551 realizes the positioning and painting function of the original lifting position through the two hole structures (the second connecting hole 553 and the third connecting hole 554) arranged at different angles.

[0051] In the actual painting process, when the internal paint spray module 5 enters the cabinet body 7 downward, at this time, the third connecting hole 554 aligns with the material conveying hole 61. The linkage assembly 57 is raised to start painting the corner position of the cabinet body 7. Then, the lifting and extruding assembly 58 is lowered to drive the second spray head 551 to rotate to make the second connecting hole 553 align with the material conveying hole 61, and the second spray head 551 aligns with the original lifting position (the lifting rod 441 has been removed from the original lifting position, and at this time, the original lifting position is a blank surface without painting) to paint.

[0052] Referring to Figure 1 、 Figure 4 、 Figure 5 、 Figure 10As shown, in order to be able to realize the corner area of the lower half of the cabinet body 7 is painted, the application is provided with a hidden second paint spraying assembly 56, specifically, the second paint spraying assembly 56 includes a rotating block 561, a telescopic spray head 562, a telescopic pipe 563, a tension spring 564, a feed hole 565, the lower end of the paint spraying box 51 is uniformly provided with a hidden groove, the rotating block 561 is rotatably arranged in the hidden groove, the upper end of the rotating block 561 is connected with the hidden groove through the tension spring 564, the telescopic spray head 562 is slidably arranged in the inner cavity of the rotating block 561, the trapezoidal tail end of the telescopic spray head 562 in the initial position is in close contact with the inner cavity of the rotating block 561, the feed hole 565 is arranged on the inclined surface of the trapezoidal tail end of the telescopic spray head 562, when the rotating block 561 is placed horizontally (hidden state), the telescopic spray head 562 is extruded by the side wall of the hidden groove and is retracted into the rotating block 561, at this time the position of the feed hole 565 is blocked by the inner cavity of the rotating block 561 to form a closed state (paint cannot be sprayed out), after the rotating block 561 is adjusted downward, the outer side of the telescopic spray head 562 is not extruded by the side wall of the hidden groove, at this time the telescopic spray head 562 can be pushed outward under the high pressure of paint delivery, so that the feed hole 565 is no longer blocked by the inner cavity wall, and the paint can be smoothly sprayed out from the telescopic spray head 562 after passing through the feed hole 565, the inner cavity of the rotating block 561 is connected with the inside of the paint spraying box 51 through the telescopic pipe 563, the second paint spraying assembly 56 is designed in a hidden manner, which ensures that the second paint spraying assembly 56 does not block the deepening of the internal paint spraying module 5 when the internal paint spraying module 5 enters the inside of the cabinet body 7.

[0053] In the actual paint spraying process, when the internal paint spraying module 5 enters the cabinet body 7 downward, the rotating block 561 is rotated by the rising of the linkage assembly 57 to change the angle, under the high pressure delivery impact of the paint, the telescopic spray head 562 is stretched to align the corner area of the lower half of the cabinet body 7, at this time the inner cavity no longer blocks the feed hole 565, the paint is delivered to the telescopic spray head 562 from the opened feed hole 565 and is sprayed out to paint the corner area of the inside of the cabinet body 7, after the paint spraying is completed, the linkage assembly 57 is lowered to reset, at this time the telescopic spray head 562 is retracted into the inner cavity of the rotating block 561 under the reset of the tension spring 564 and the extrusion of the inclined surface of the hidden groove.

[0054] Referring to Figures 4-7As shown, in order to realize the switching control function of the first paint spraying assembly 53 and the paint supplement assembly 55, the application is provided with a linkage assembly 57, specifically, the linkage assembly 57 comprises a connecting cylinder 571, a connecting frame 572, a connecting rope 573, a blocking plate 574, and a communication hole 575. The connecting cylinder 571 is fixedly installed at the middle part of the paint spraying box body 51. The upper end of the connecting cylinder 571 is connected with the connecting frame 572. The lower end of the connecting frame 572 is connected with the rotating block 561 through the connecting rope 573. The upper end of the connecting frame 572 is installed with the blocking plate 574. The upper end of the blocking plate 574 is provided with the communication hole 575. When the linkage assembly 57 is at the initial position, the communication hole 575 at the upper end of the blocking plate 574 is in the state of being blocked from the discharge hole 60 and the material conveying hole 61, so as to ensure that the first paint spraying assembly 53 and the paint supplement assembly 55 are closed (to prevent early spraying). When the connecting cylinder 571 drives the blocking plate 574 to move upward, the communication hole 575 is communicated with the discharge hole 60 and the material conveying hole 61. At this time, the first paint spraying assembly 53 and the paint supplement assembly 55 are opened.

[0055] In the actual working process, when the inside corner position of the cabinet body 7 needs to be painted, the connecting cylinder 571 drives the connecting frame 572 to rise to the highest position. At this time, the communication hole 575 in the blocking plate 574 which rises synchronously is aligned with the discharge hole 60 and the material conveying hole 61. Moreover, the rising connecting frame 572 simultaneously pulls the connecting rope 573 to make the second paint spraying assembly 56 adjust the overall angle, so as to ensure that the telescopic spray head 562 can be extended to spray paint when the paint is conveyed.

[0056] Referring to Figures 3-4 , Figures 6-9 , Figure 10 As shown, in order to realize the functions of supplementing paint to the contact area between the boom 441 and the inside of the cabinet body 7 and rotating the angle of the second spray head 551, the application cooperates between the lifting extrusion assembly 58 and the supporting assembly 54, so as to support the cabinet body 7 again by the supporting assembly 54 when the boom 441 is withdrawn. Specifically, the lifting extrusion assembly 58 comprises an extrusion plate 581, a linkage rope 582, and a telescopic cylinder 583. The telescopic cylinder 583 is connected between the extrusion plate 581 and the connecting plate, so as to drive the lifting of the extrusion plate 581. The upper end of the extrusion plate 581 is uniformly provided with extrusion pieces 59, which can extrude the tenon 444. The extrusion plate 581 is connected with the second spray head 551 through the linkage rope 582, so as to drive the rotation of the second spray head 551. The lifting extrusion assembly 58 realizes the automatic pop-up of the hoisting assembly 44 and the angle rotation function of the second spray head 551 through lifting.

[0057] The support assembly 54 comprises a conical sliding block 541, a support plate 542, a spring 543, and a top support rod 544. The upper end of the paint spraying box 51 is provided with a sliding groove. The conical sliding block 541 is slidingly arranged in the sliding groove and connected with the paint spraying box 51 through the spring 543. The conical sliding block 541 is connected with the support plate 542 through a pin shaft. The support plate 542 is arranged on the top support rod 544. When the conical sliding block 541 moves to the outermost position, the support plate 542 supports the cabinet body 7. The top support rod 544 is arranged at the upper end of the paint spraying box 51. The arrangement of the support assembly 54 ensures that the support plate 542 can timely support the cabinet body 7 during the process that the lifting rod 441 is withdrawn from the upper end of the cabinet body 7.

[0058] In the actual working process, when the original hoisting position needs to be repainted, the telescopic cylinder 583 drives the extrusion plate 581 to descend, thereby pressing the conical sliding block 541 to move outward (the support plate 542 is inclinedly moved under the extrusion of the top end of the top support rod 544). At the same time, the extrusion piece 59 extrudes the tenon 444, so that the lifting rod 441 is withdrawn from the original hoisting position. At this time, the outwardly inclined support plate 542 supports the upper end of the cabinet body 7 (the support point is different from the hoisting point of the lifting rod 441). In the descending process of the extrusion plate 581, the linkage rope 582 is synchronously driven, thereby driving the second spray head 551 to rotate so as to align the original hoisting position for repainting.

[0059] The implementation principle of the embodiment is as follows:

[0060] Step one, hoisting: hoist the cabinet body 7 placed in front of the external paint spraying box 1 for painting;

[0061] Step two, moving: move the cabinet body 7 to the position between the internal paint spraying module 5 and the external paint spraying box 1 through the driving of the electric sliding block one 45;

[0062] Step three, placing: place the cabinet body 7 outside the internal paint spraying module 5 through the rising of the electric telescopic rod 41. Place the cabinet body 7 and the internal paint spraying module 5 into the internal paint spraying module 5 through the descending of the electric sliding block two 6.

[0063] Step four, painting: after the cabinet body 7 is placed at the specified position, the conveying pump 34 conducts paint conveying to the internal paint spraying module 5 and the external paint spraying box 1 through the hose 35 and the conveying pipe 33. At this time, the connecting cylinder 571 drives the connecting frame 572 to rise to the highest position. The communication hole 575 in the blocking plate 574 rises synchronously. The outlet hole 60 and the conveying hole 61 are aligned. The rising connecting frame 572 simultaneously pulls the connecting rope 573, so that the telescopic spray head 562 is extended. The paint sprays the inside and outside of the cabinet body 7 through the first spray head 531, the telescopic spray head 562, the paint spraying hole one 12, and the paint spraying hole two 52 in the opened state.

[0064] Step five, paint the original hoisting position: after the completion of the large area paint spraying, the telescopic cylinder 583 drives the extrusion plate 581 to descend, and the tapered sliding block 541 is pressed to move outward, at the same time, the extrusion part 59 extrudes the tenon 444, so that the boom 441 gradually withdraws from the original hoisting position, at this time, the support plate 542 which moves outward and inclines supports the upper end of the cabinet 7 (the support point has been painted at this time), the linkage rope 582 drives the second spray head 551 to rotate through the descent of the extrusion plate 581 so as to be aligned with the original hoisting position, at this time, the original hoisting position is painted through the opened paint supplement assembly;

[0065] Step six, the paint spraying is completed.

[0066] The above only describes certain exemplary embodiments of the present application in a descriptive way, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
