Description

Technical Field

[0001] The utility model relates to the technical field of control cabinet equipment, and more specifically, to a spraying device for the surface of a control cabinet. Background Technique

[0002] A control cabinet assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for the normal operation of the power system, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment. During normal operation, the circuit can be connected or disconnected manually or automatically through switches. In case of faults or abnormal operation, the protective electrical appliances can cut off the circuit or give an alarm. The measuring instruments can display various parameters during operation, and some electrical parameters can also be adjusted to prompt or send signals for deviations from the normal working state.

[0003] During the production process of the control cabinet, it is necessary to spray the surface of the control cabinet to achieve the purposes of rust prevention, protection, and aesthetics. After spraying one side of the control cabinet with the existing spraying device, it is necessary to rotate and adjust the position of the control cabinet, and then spray the other side of the control cabinet. The spraying step and the step of rotating and adjusting the position of the control cabinet are interspersed. The switching between the two steps usually requires manual operation, which may cause untimely switching due to the fatigue of workers, resulting in an extended spraying time and a reduced processing efficiency. In view of this, we propose a spraying device for the surface of a control cabinet. Summary of the Invention

A spray head is fixedly connected to the side of the moving block close to the carrier plate. A spraying box for conveying paint into the spray head is installed on the top of the spraying chamber.

[0009] As a further improvement of the present technical solution, the driving mechanism includes two sliding plates slidably arranged on the inner wall of the activity slot. The two sliding plates are respectively located above and below the moving block. A vertical rack is fixedly connected to the side of the sliding plate close to the moving block. An external frame is fixedly connected to the side of the assembly frame away from the spray head. A transmission gear is rotatably connected to the side wall of the external frame.

[0012] Compared with the prior art, the beneficial effects of the present utility model:

[0013] The control cabinet surface spraying device places the control cabinet on a carrier plate, and after the vertically reciprocating spray head completes the spraying work on one side of the control cabinet, the carrier plate automatically drives the control cabinet to rotate 90 degrees, and rotates the unsprayed side of the control cabinet to a position facing the spray head, and the spray head then sprays the next side of the control cabinet, shortening the interval between the spraying step and the turning step, reducing the time spent on spraying all sides of the control cabinet, and improving the spraying efficiency.

[0025] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0026] Please refer to Figure 1 and Figure 3 As shown, this embodiment provides a spraying device for the surface of a control cabinet, including a spraying chamber 1. A carrier plate 6 is arranged near the bottom inside the spraying chamber 1. The upper surface of the carrier plate 6 is used to place the control cabinet. A steering mechanism 5 is arranged between the lower part of the carrier plate 6 and the spraying chamber 1. The steering mechanism 5 is used to drive the carrier plate 6 to rotate, so that the control cabinet placed on the upper surface of the carrier plate 6 rotates synchronously. One side of the spraying chamber 1 is fixedly connected with an assembly frame 2. A spraying mechanism 3 is arranged on the assembly frame 2. The spraying mechanism 3 sprays paint on the control cabinet placed on the carrier plate 6. After the spraying mechanism 3 sprays paint on one side of the surface of the control cabinet, by driving the carrier plate 6 to drive the control cabinet to rotate, the side of the control cabinet facing the spraying mechanism 3 is changed, so that the spraying mechanism 3 can spray paint on other sides of the surface of the control cabinet. The steering mechanism 5 includes a bottom plate 54 slidably arranged at the bottom inside the spraying chamber 1. A slideway 52 is opened at the bottom inside the spraying chamber 1. The bottom plate 54 is slidably connected with the inner wall of the slideway 52. A spring 58 is fixedly connected between the side of the bottom plate 54 away from the assembly frame 2 and the inner wall of the slideway 52. One end of the bottom plate 54 penetrates through the spraying chamber 1 and is provided with a driving mechanism 4. The driving mechanism 4 is arranged on the side of the assembly frame 2 outside the spraying chamber 1. When the spraying mechanism 3 pushes the driving mechanism 4 to move vertically, the driving mechanism 4 pushes the steering mechanism 5 to move horizontally in a direction away from the assembly frame 2, so that the steering mechanism 5 drives the carrier plate 6 to rotate. After the spraying mechanism 3 finishes spraying one side of the control cabinet, the spraying mechanism 3 triggers the steering mechanism 5 through the driving mechanism 4, so that the steering mechanism 5 drives the carrier plate 6 and the control cabinet to rotate, and rotates the next side of the control cabinet to the position facing the spraying mechanism 3, so that the spraying mechanism 3 sprays the next side of the control cabinet. When the bottom plate 54 in the steering mechanism 5 moves horizontally in a direction away from the assembly frame 2, the spring 58 elastically contracts. When the driving mechanism 4 stops pushing the steering mechanism 5, the spring 58 rebounds to drive the steering mechanism 5 to reset, and restores the function of the steering mechanism 5 to drive the carrier plate 6 to rotate. In this way, the comprehensive spraying of all sides of the control cabinet is realized. Through the coordination of the driving mechanism 4, the spraying mechanism 3 and the steering mechanism 5 operate alternately, shortening the time consumed for spraying all sides of the control cabinet and improving the spraying efficiency.

[0027] In order to comprehensively spray one side of the control cabinet placed on the carrier plate 6, the structure of the spraying mechanism 3 is refined below. Refer to Figure 2, the spraying mechanism 3 includes a reciprocating lead screw 31 vertically arranged inside the assembly frame 2. The two ends of the reciprocating lead screw 31 are respectively rotatably connected to the top and bottom of the assembly frame 2. A motor 32 for driving the reciprocating lead screw 31 to rotate is installed at the top of the assembly frame 2. A moving block 33 is threadedly connected to the reciprocating lead screw 31. An activity slot 35 is formed on one side of the assembly frame 2. The moving block 33 is slidably arranged on the inner wall of the activity slot 35. When the output shaft of the motor 32 drives the reciprocating lead screw 31 to rotate, due to the threaded connection between the reciprocating lead screw 31 and the moving block 33, the moving block 33 vertically reciprocates along the inner wall of the activity slot 35. A spray head 34 is fixedly connected to one side of the moving block 33 close to the carrier plate 6. A spraying box 36 for conveying paint into the spray head 34 is installed at the top of the spraying chamber 1. After placing the control cabinet on the upper surface of the carrier plate 6, adjust the initial position of the control cabinet so that the side of the control cabinet close to the spray head 34 is parallel to the spray head 34. The initial position of the spray head 34 is close to the bottom of the control cabinet. When the spraying box 36 conveys paint into the spray head 34, the spray head 34 can spray the paint to the lower end of one side of the control cabinet. Then, the moving block 33 drives the spray head 34 to move vertically upward. During the upward movement, the spray head 34 sprays the paint from bottom to top onto one side of the control cabinet until the paint is sprayed to the upper end of one side of the control cabinet, achieving a full spraying of one side of the control cabinet.

[0028] When the moving block 33 drives the spray head 34 to move upward and the spray head 34 sprays the paint to the upper end of one side of the control cabinet, the continuous upward movement of the moving block 33 will trigger the driving mechanism 4. The driving mechanism 4 pushes the steering mechanism 5 to horizontally move away from the assembly frame 2, causing the steering mechanism 5 to drive the carrier plate 6 and the control cabinet to rotate 90 degrees, rotating the next side of the control cabinet to a position parallel to the spray head 34. At this time, the moving block 33 reaches the upper end of the thread of the reciprocating lead screw 31, and the moving block 33 changes to drive the spray head 34 to move vertically downward. The spray head 34 sprays the paint from top to bottom onto the side of the control cabinet currently facing the spray head 34. After the spray head 34 sprays the paint to the lower end of one side of the control cabinet to complete the full spraying of this side, the continuous downward movement of the moving block 33 will also trigger the driving mechanism 4, causing the steering mechanism 5 to drive the carrier plate 6 and the control cabinet to rotate 90 degrees again, and the spray head 34 sprays the paint from bottom to top onto the side wall of the control cabinet. In this way, after the spray head 34 moves vertically in one direction to complete the spraying work on one side of the control cabinet, the control cabinet rotates 90 degrees to switch the side facing the spray head 34, and the spray head 34 moves vertically in the opposite direction to complete the spraying work on this side, achieving a full spraying of all sides of the control cabinet.

[0029] In the above spraying process, when the moving block 33 drives the spray head 34 to move vertically, and after the spray head 34 completes the spraying work on one side of the control cabinet, whether the spray head 34 continues to move upward vertically or continues to move downward vertically, it is necessary to be able to trigger the driving mechanism 4, so that the driving mechanism 4 pushes the steering mechanism 5 to move horizontally away from the assembly rack 2, rotates and adjusts the position of the control cabinet. To achieve this function of the driving mechanism 4, the structure of the driving mechanism 4 is refined as follows. Refer to Figure 3 , the driving mechanism 4 includes two sliding plates 41 slidably arranged on the inner wall of the movable groove 35. The two sliding plates 41 are respectively located above and below the moving block 33. A vertical rack 42 is fixedly connected to the side of the sliding plate 41 close to the moving block 33. An external rack 43 is fixedly connected to the side of the assembly rack 2 away from the spray head 34. A transmission gear 44 is rotatably connected to the side wall of the external rack 43. The two vertical racks 42 are respectively meshed and connected to both sides of the transmission gear 44. A wedge block 46 is fixedly connected to the bottom of the lower external rack 43. One side of the bottom plate 54 located outside the spraying chamber 1 is set as an inclined surface. The lower end of the wedge block 46 is in contact with the inclined surface of the bottom plate 54. After the spray head 34 completes the spraying work on one side of the control cabinet, the moving block 33 moves to a position in contact with one of the sliding plates 41. The following is a classification discussion of the subsequent movement state of the moving block 33:

[0030] If the moving block 33 drives the spray head 34 to continue to move upward, the moving block 33 is in contact with the upper sliding plate 41. The upward moving moving block 33 synchronously lifts the upper sliding plate 41 upward. The sliding plate 41 drives the vertical rack 42 fixedly connected to it to move upward synchronously, drives the transmission gear 44 to rotate, and the transmission gear 44 drives the other vertical rack 42 to move vertically downward, so that the lower sliding plate 41 fixedly connected to the vertical rack 42 moves downward synchronously. When the lower sliding plate 41 drives the wedge block 46 to move downward, the wedge block 46 will press the bottom plate 54 downward. When the inclined surface of the bottom plate 54 receives the pressing force, the bottom plate 54 will move horizontally along the inner wall of the slideway 52 away from the assembly rack 2, causing the spring 58 to contract elastically. When the bottom plate 54 moves horizontally, the wedge block 46 will slide downward along the inclined surface of the bottom plate 54, and the horizontal movement of the bottom plate 54 is used to drive the steering mechanism 5 to rotate, and then the position of the control cabinet is adjusted by the rotation of the steering mechanism 5;

[0031] When the moving block 33 drives the nozzle 34 to continue moving downward, the moving block 33 contacts the lower slide plate 41. The moving block 33 during downward movement drives the lower slide plate 41 to move downward synchronously. When the lower slide plate 41 drives the wedge block 46 to move downward, the bottom plate 54 will horizontally move along the inner wall of the slideway 52 away from the assembly frame 2, causing the spring 58 to contract elastically. By the horizontal movement of the bottom plate 54, the steering mechanism 5 is driven to rotate. After the nozzle 34 completes the spraying work on one side of the control cabinet, whether the nozzle 34 continues to move vertically upward or continues to move vertically downward, the driving mechanism 4 can be triggered, enabling the driving mechanism 4 to act on the steering mechanism 5 and causing the steering mechanism 5 to rotate to adjust the position of the control cabinet.

[0032] After the lower slide plate 41 moves downward to drive the steering mechanism 5, in order to reset the two slide plates 41 and ensure that the moving block 33 during subsequent movement can contact the slide plate 41 and trigger the driving mechanism 4 again, causing the steering mechanism 5 to intermittently rotate to adjust the positions of the carrier plate 6 and the control cabinet. A winding spring 45 is fixedly connected to the outer wall of the rotating shaft of the transmission gear 44. One end of the winding spring 45 is fixedly connected to the external frame 43. When the moving block 33 pushes any one of the slide plates 41 to move vertically, the vertical rack 42 fixedly connected to the slide plate 41 moves synchronously, driving the transmission gear 44 to rotate and causing the winding spring 45 to contract elastically. After the lower slide plate 41 completes the driving of the steering mechanism 5, the moving block 33 moves towards the direction close to the transmission gear 44, and the rebound of the winding spring 45 drives the transmission gear 44 to rotate in the reverse direction. Through the meshing transmission between the two vertical racks 42 and the transmission gear 44, the two vertical racks 42 respectively drive the two slide plates 41 to move towards the direction close to the transmission gear 44, thereby resetting the slide plates 41 and ensuring that the moving block 33 during subsequent movement can continue to push the slide plate 41 to move, intermittently triggering the driving mechanism 4, and causing the steering mechanism 5 to intermittently rotate to adjust the positions of the carrier plate 6 and the control cabinet.

[0033] During the reset process of the two slide plates 41, the lower slide plate 41 drives the wedge block 46 to move vertically upward. After the wedge block 46 stops pressing the bottom plate 54 downward, the spring 58 rebounds to push the bottom plate 54 to horizontally move towards the direction close to the assembly frame 2, ensuring that the inclined surface of the bottom plate 54 is always in contact with the wedge block 46. After the two slide plates 41 are reset, the bottom plate 54 is also reset, thereby restoring the function of the steering mechanism 5 to drive the carrier plate 6 to rotate and realizing the full spraying of all sides of the control cabinet.

[0034] When the bottom plate 54 horizontally moves away from the external frame 43, the steering mechanism 5 will drive the carrier plate 6 to rotate, thereby rotating and adjusting the position of the control cabinet placed on the carrier plate 6. To achieve this function, the following further details the remaining structures of the steering mechanism 5 except the bottom plate 54. Refer to Figure 4 and Figure 5, the steering mechanism 5 further includes a positioning ring 51 fixedly connected to the inner bottom surface of the spraying chamber 1. The carrier plate 6 is rotatably arranged on the top of the positioning ring 51. A fixed gear 53 is fixedly connected to the center of the lower surface of the carrier plate 6. A one-way meshing rack assembly 55 is arranged on the upper surface of the bottom plate 54. When the one-way meshing rack assembly 55 moves, it drives the fixed gear 53 to rotate. Both the one-way meshing rack assembly 55 and the fixed gear 53 are arranged inside the positioning ring 51. When the bottom plate 54 moves horizontally away from the external frame 43, the bottom plate 54 drives the one-way meshing rack assembly 55 to move, causing the one-way meshing rack assembly 55 to drive the fixed gear 53 to rotate. At this time, the rotating fixed gear 53 drives the carrier plate 6 to rotate along the circumferential outer wall of the positioning ring 51. During the rotation of the carrier plate 6, the carrier plate 6 adjusts the position of the control cabinet placed on its upper surface, so as to facilitate the spray head 34 to spray the outer surface of the control cabinet comprehensively.

[0035] In order to enable the bottom plate 54 to only move horizontally along a fixed path in the slideway 52, a guide rod 56 is fixedly connected to the inner wall of the slideway 52. A chute 57 is opened on the side of the bottom plate 54 away from the assembly frame 2. The chute 57 is slidably sleeved on the outside of the guide rod 56. A spring 58 is sleeved on the outside of the guide rod 56. When the bottom plate 54 moves horizontally along the inner wall of the slideway 52, the chute 57 moves horizontally synchronously along the outer wall of the guide rod 56. The cooperation between the chute 57 and the guide rod 56 plays a guiding role for the bottom plate 54, improving the stability of the bottom plate 54 during the horizontal movement.

[0036] When the moving block 33 pushes the sliding plate 41 to move, the stroke length of the sliding plate 41 is fixed. Therefore, during the process of the sliding plate 41 pushing the bottom plate 54 to move through the wedge block 46, the stroke lengths of the bottom plate 54 and the one-way meshing rack assembly 55 are also fixed. After the bottom plate 54 drives the one-way meshing rack assembly 55 to move horizontally away from the external frame 43 to the maximum stroke, the fixed gear 53 drives the carrier plate 6 to rotate 90 degrees, rotating the unsprayed side of the control cabinet to a position parallel to the spray head 34. After rotating the control cabinet 90 degrees, the sliding plate 41 returns to its original position under the rebounding action of the coil spring 45, and the bottom plate 54 also moves horizontally towards the external frame 43 under the rebounding push of the spring 58. The one-way meshing rack assembly 55 following the external frame 43 does not mesh with the fixed gear 53, so that the fixed gear 53 does not drive the carrier plate 6 and the control cabinet to rotate, and the spraying operation of the spray head 34 on the side wall of the control cabinet is not affected.

[0037] In order to enable the one-way meshing rack assembly 55 to drive the fixed gear 53 to rotate when moving horizontally away from the external frame 43, and to prevent the one-way meshing rack assembly 55 from driving the fixed gear 53 to rotate when the one-way meshing rack assembly 55 moves horizontally towards the external frame 43 following the bottom plate 54, ensuring that the control cabinet can only rotate in one direction and the spraying operation of the spray head 34 on the side wall of the control cabinet is not affected, the structure of the one-way meshing rack assembly 55 is refined as follows. Refer to Figure 5, the one-way meshing rack assembly 55 includes a bump 551 fixedly connected to the upper surface of the bottom plate 54. A number of engaging teeth 552 are linearly arrayed and hinged on one side of the bump 551 close to the fixed gear 53. One end of one engaging tooth 552 is located inside the card slot of the fixed gear 53. A baffle 553 is extrusion-fitted on one side of the engaging tooth 552 close to the assembly frame 2, and a tension spring 554 is fixedly connected to one side of the engaging tooth 552 close to the baffle 553. One side of the baffle 553 and the tension spring 554 are both fixedly connected to the bump 551. When the bottom plate 54 drives the bump 551 to horizontally move away from the external frame 43, one side of one engaging tooth 552 away from the assembly frame 2 is extrusion-fitted with the inner wall of the fixed gear 53. The baffle 553 restricts the engaging tooth 552 from flipping under the action of the reaction force, so that the engaging tooth 552 remains perpendicular to the bump 551.

[0038] This engaging tooth 552 pushes the fixed gear 53 to rotate, so that the next engaging tooth 552 turns into the next tooth slot of the fixed gear 53. Repeat the above process to make a number of engaging teeth 552 push the fixed gear 53 to rotate in turn. When the bottom plate 54 drives the bump 551 to horizontally move towards the external frame 43, after one side of one engaging tooth 552 close to the assembly frame 2 is extrusion-fitted with the fixed gear 53, since the baffle 553 no longer restricts the engaging tooth 552 from flipping, the engaging tooth 552 flips away from the baffle 553 until the engaging tooth 552 moves out of the tooth slot of the fixed gear 53. The next engaging tooth 552 that turns into the tooth slot of the fixed gear 53 also repeats this process, so that a number of engaging teeth 552 cannot drive the fixed gear 53 to rotate. During the flipping process of the engaging tooth 552, the tension spring 554 is elastically stretched. When the engaging tooth 552 moves to one side of the fixed gear 53 close to the assembly frame 2, the tension spring 554 rebounds to pull the engaging tooth 552 to the position where it is extrusion-fitted with the baffle 553, and returns to the state perpendicular to the bump 551, ensuring that when the engaging tooth 552 subsequently moves horizontally away from the assembly frame 2, it can continue to drive the fixed gear 53 to rotate, so that the reciprocating moving bottom plate 54 can only unidirectionally rotate to adjust the position of the control cabinet, and the work of spraying each side wall of the control cabinet by the spray head 34 in turn is not affected.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
