Description

Technical Field

[0001] This utility model relates to the field of distribution box production technology, specifically a powder coating mechanism for distribution box production with uniform material output. Background Technology

[0002] Distribution boxes are typically installed in various indoor and outdoor environments and are subject to varying degrees of corrosion. To prevent chemical corrosion on the outer surface of metal distribution boxes, a powder coating is needed to provide isolation. Therefore, a powder coating device is required.

[0003] A Chinese patent with authorization announcement number CN219519231U discloses a powder coating device for the production of distribution boxes. The device includes a second partition, with a powder coating chamber above the partition and a recovery chamber below it. A T-shaped groove is symmetrically formed on the top surface of the partition, and a T-shaped slider is slidably connected to the inner wall of the groove. A motor slot is formed on the top surface of the worktable, and a second motor is fixedly connected to the inner wall of the slot. The output rod of the second motor is fixedly connected to a support plate. This invention uses a backward sliding clamping block to place the distribution box to be powder coated onto a fixed plate. The distribution box is fixed between the clamping blocks by the pushing force of a spring, facilitating the fixing and removal of the distribution box, and also making it convenient to fix distribution boxes of different sizes.

[0004] However, the above-mentioned device still has some problems. In practical applications, if the powder coating is not sieved, it will contain particles of different sizes. Due to the uneven particle size, some particles will be difficult to atomize and disperse, thus failing to achieve uniform discharge and reducing the powder coating effect. Therefore, in order to solve the above problems, a distribution box powder coating mechanism with uniform discharge is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a uniform material discharge distribution box powder coating production mechanism.

[0007] Preferably, a pump is installed on the top side of the box, the pump's inlet end is connected to a discharge pipe, one end of the discharge pipe is connected to a storage cylinder, the pump's outlet end is connected to a conveying pipe, an installation plate is installed inside the top side of the box, an L-shaped pipe is installed on the bottom side of the installation plate, one end of the conveying pipe is connected to the L-shaped pipe, and several nozzles are installed at equal intervals at both ends of the L-shaped pipe, which can realize uniform powder coating operation on the outer surface of the distribution box and improve production efficiency.

[0008] Preferably, a mounting shell is installed on the bottom side of the enclosure, a servo motor is installed inside the mounting shell, a support plate is installed at the output end of the servo motor, two slide rails are symmetrically opened inside the top side of the support plate, a fixing plate is slidably installed in each slide rail, a screw hole is opened inside the bottom end of each fixing plate, a double-ended lead screw is threaded into the screw hole, the double-ended lead screw passes through the slide rail and is rotatably installed in the support plate, and a handle is fixed to one end of the double-ended lead screw, which can flexibly fix distribution boxes of different sizes.

[0009] Preferably, each of the fixed clamps has a circular groove inside its top end. A movable rod is slidably installed through the circular groove inside the fixed clamp. A circular block is installed at one end of the movable rod, and a pressing block is installed at the other end. A tension spring is fixedly connected between the fixed clamp and the pressing block. The tension spring is sleeved on the outside of the movable rod. An L-shaped frame is installed on one side of the fixed clamp. Each L-shaped frame is equipped with a trigger alarm. The trigger alarm is used to monitor the pressure of the pressing block on the L-shaped frame, to avoid over-clamping the distribution box, and to protect the distribution box from damage.

[0010] Preferably, a hinged door is installed on one side of the enclosure, and a handle is fixed to one side of the door to facilitate the handling of the distribution box during processing.

[0011] Preferably, a control panel is installed on the other side of the enclosure via a hinge. The control panel is electrically connected to the trigger alarm and is used for signal transmission and operation control of the trigger alarm, thereby improving the automation level of the device.

[0012] The advantages of this utility model are:

[0013] 1. When the drive motor of this utility model starts, it drives the rotating shaft and cam to rotate. When the cam is raised, it pushes the slide plate to slide along the slide groove to one side. The other side of the slide plate squeezes the push plate to slide along the T-shaped rod and compresses the compression spring. When the raised position leaves the slide plate, the compression spring rebounds and pushes the push plate back to its original position, which in turn pushes the slide plate to slide to the other side. In this way, the slide plate drives the screen plate to vibrate back and forth. When the powder coating passes through the screen plate, large powder particles are screened out, and only powder with uniform particle size enters the storage cylinder, ensuring the uniformity of subsequent discharge.

During the movement of the fixed clamping plate of this utility model, the circular block will first contact the inner side of the distribution box and drive the movable rod to slide into the fixed clamping plate. The circular block enters the interior of the circular groove, and the tension spring is stretched. As the fixed clamping plate continues to approach the distribution box, the pressing block gradually approaches and contacts the trigger alarm. The trigger alarm will send a signal to the control panel. The control panel can control the trigger alarm to sound an alarm, avoiding excessive clamping of the distribution box and protecting the distribution box from damage. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a powder coating production mechanism for a uniformly discharging electrical distribution box includes a housing 1. A storage cylinder 2 is installed on the top side of the housing 1. A feed pipe 3 is connected to the top side of the storage cylinder 2. A groove 4 is formed inside the bottom end of the feed pipe 3. A sliding plate 5 is slidably installed through the groove 4. A screen plate 6 is assembled at the center of the sliding plate 5. A support column 7 is installed on the outer side of the top end of the feed pipe 3. A drive motor 8 is installed on one side of the support column 7. A rotating shaft 9 is installed at the output end of the drive motor 8. A cam 10 is installed on the outer side of the rotating shaft 9. The protruding part of the cam 10 will contact one side of the slide plate 5 during operation. A support seat 11 is fixedly connected to the outer side of the storage cylinder 2. A T-shaped rod 12 is slidably installed inside the support seat 11. A push plate 13 is fixedly connected to one end of the T-shaped rod 12. When the slide plate 5 moves, its other side will contact the push plate 13. A compression spring 14 is fixedly connected between the push plate 13 and the support seat 11. The compression spring 14 is sleeved on the outer side of the T-shaped rod 12.

[0024] A pump 15 is installed on the top side of the housing 1. The pump 15 has an inlet end connected to a discharge pipe 16, one end of which is connected to a storage cylinder 2. A conveying pipe 17 is connected to the discharge end of the pump 15. An mounting plate 18 is installed inside the top side of the housing 1. An L-shaped pipe 19 is installed on the bottom side of the mounting plate 18. One end of the conveying pipe 17 is connected to the L-shaped pipe 19. Several nozzles 20 are equidistantly installed at both ends of the L-shaped pipe 19. During operation, in practical applications, if the powder coating is not sieved, it will contain particles of varying sizes. Due to the uneven particle size, some particles will be difficult to atomize and disperse, thus failing to achieve uniform discharge and reducing the powder coating effect. The powder coating... Feed pipe 3 enters storage cylinder 2, drive motor 8 starts, drives rotating shaft 9 and cam 10 to rotate. When the protruding position of cam 10 contacts one side of slide plate 5, it pushes slide plate 5 to slide along slide groove 4 to one side. At this time, the other side of slide plate 5 will squeeze push plate 13. Push plate 13 slides along T-shaped rod 12 and compresses compression spring 14. When cam 10 continues to rotate and the protruding position leaves slide plate 5, compression spring 14 rebounds, pushes push plate 13 back to its original position, and then pushes slide plate 5 to slide to the other side. In this way, slide plate 5 drives screen plate 6 to vibrate back and forth. When powder coating passes through screen plate 6, large powder particles are screened out, and only powder with uniform particle size enters storage cylinder 2, ensuring the uniformity of subsequent discharge.

[0025] Pump 15 starts, drawing the screened powder coating from storage cylinder 2 through discharge pipe 16, then conveying it through conveying pipe 17 to L-shaped pipe 19, and finally spraying it out from nozzles 20 installed at equal intervals at both ends of L-shaped pipe 19. Because the nozzles 20 are evenly distributed and the powder coating has a uniform particle size, it can be evenly sprayed on the outer surface of the distribution box under the action of static electricity, which improves production efficiency and powder coating quality.

[0026] Please see Figure 1 , 2 As shown in Figure 5, a mounting shell 21 is installed on the bottom side of the housing 1. A servo motor 22 is installed inside the mounting shell 21. A support plate 23 is installed at the output end of the servo motor 22. Two slide rails 24 are symmetrically opened inside the top side of the support plate 23. A fixed clamping plate 25 is slidably installed inside each slide rail 24. A screw hole is opened inside the bottom end of each fixed clamping plate 25. A two-way lead screw 26 is threaded into the screw hole. The two-way lead screw 26 passes through the slide rail 24 and is rotatably installed inside the support plate 23. A handle 27 is fixedly connected to one end of the two-way lead screw 26.

[0027] The top of each fixed clamp 25 has a circular groove 28. A movable rod 29 is slidably installed through the circular groove 28 inside the fixed clamp 25. A circular block 30 is installed at one end of the movable rod 29, and a pressing block 31 is installed at the other end. A tension spring 32 is fixedly connected between the fixed clamp 25 and the pressing block 31. The tension spring 32 is sleeved on the outside of the movable rod 29. An L-shaped frame 33 is installed on one side of the fixed clamp 25. Each L-shaped frame 33 is equipped with a trigger alarm 34. The trigger alarm 34 is used to monitor the pressure of the pressing block 31 on the L-shaped frame 33. A movable door 35 is installed on one side of the box 1 through a hinge. A handle 36 is fixedly connected to one side of the movable door 35. A control panel 37 is installed on the other side of the box 1 through a hinge. During operation, the distribution box is usually installed in various indoor and outdoor environments and will be affected by different degrees of corrosion. In order to avoid chemical corrosion on the outer surface of the metal distribution box, it is necessary to spray... The coating formed by the plastic can play an isolation role. In order to ensure the stability of the distribution box during the powder coating, the movable door 35 is first opened by the handle 36, and the distribution box is placed on the outside of the two fixed clamps 25. Then, the handle 27 is turned, and the handle 27 drives the double-acting screw 26 to rotate, so that the fixed clamps 25 move towards each other along the slide rail 24 and gradually approach the inner walls of the two sides of the distribution box. During this process, the circular block 30 will first contact the inner side of the distribution box and drive the movable rod 29 to slide into the fixed clamp 25. The circular block 30 enters the interior of the circular groove 28, and the tension spring 32 is stretched. As the fixed clamps 25 continue to approach the distribution box, the pressing block 31 gradually approaches and contacts the trigger alarm 34. When the pressure reaches the set value of the trigger alarm 34, the trigger alarm 34 will send a signal to the control panel 37. The control panel 37 can control the trigger alarm 34 to sound an alarm to avoid excessive clamping of the distribution box and protect the distribution box from damage. The specific model of the trigger alarm 34 is BBJ-ZR220V.

[0028] Then close the movable door 35, start the servo motor 22, and the output end of the servo motor 22 drives the support plate 23 to rotate, which in turn can adjust the rotation of the clamped distribution box, thereby enabling a comprehensive powder coating operation on the outer surface of the distribution box. After the processing is completed, open the movable door 35 again, turn the handle 27 in the opposite direction to release the fixing clamp 25, and the distribution box can be taken out.

[0029] Working principle: Powder coating enters storage cylinder 2 through feed pipe 3. Drive motor 8 starts, driving rotating shaft 9 and cam 10 to rotate. When the protruding position of cam 10 contacts one side of slide plate 5, it pushes slide plate 5 to slide along slide groove 4 to one side. At this time, the other side of slide plate 5 will squeeze push plate 13. Push plate 13 slides along T-shaped rod 12 and compresses compression spring 14. When cam 10 continues to rotate and the protruding position leaves slide plate 5, compression spring 14 rebounds, pushing push plate 13 back to its original position, and then pushing slide plate 5 to slide to the other side. In this way, slide plate 5 drives screen plate 6 to vibrate back and forth. When powder coating passes through screen plate 6, large powder particles are screened out, and only powder with uniform particle size enters storage cylinder 2, ensuring the uniformity of subsequent discharge.

[0030] First, open the movable door 35 using handle 36, place the distribution box on the outside of the two fixed clamps 25, and then turn the handle 27. The handle 27 drives the bidirectional lead screw 26 to rotate, causing the fixed clamps 25 to move towards each other along the slide rail 24, gradually approaching the inner walls of both sides of the distribution box. During this process, the circular block 30 will first contact the inside of the distribution box and drive the movable rod 29 to slide into the fixed clamp 25. The circular block 30 enters the interior of the circular groove 28, and the tension spring 32 is stretched. As the fixed clamps 25 continue to approach the distribution box, the pressing block 31 gradually approaches and contacts the trigger alarm 34. When the pressure reaches the set value of the trigger alarm 34, the trigger alarm 34 will send a signal to the control panel 37. The control panel 37 can control the trigger alarm 34 to sound an alarm, avoiding excessive clamping of the distribution box and protecting the distribution box from damage. The specific model of the trigger alarm 34 is BBJ-ZR220V.

[0031] Then close the movable door 35, start the servo motor 22, and the output end of the servo motor 22 drives the support plate 23 to rotate, thereby adjusting the rotation of the clamped distribution box, so as to realize the comprehensive powder coating operation on the outer surface of the distribution box.

[0032] Pump 15 starts, sucking the screened powder coating in storage cylinder 2 through discharge pipe 16, then conveying it through conveying pipe 17 to L-shaped pipe 19, and finally spraying it out from nozzles 20 installed at equal intervals at both ends of L-shaped pipe 19. Because the nozzles 20 are evenly distributed and the powder coating has a uniform particle size, it can be evenly sprayed on the outer surface of the distribution box under the action of static electricity, which improves production efficiency and powder coating quality.

[0033] After processing is complete, open the movable door 35 again, turn the handle 27 in the opposite direction to loosen the fixing clamp 25, and then you can take out the distribution box.
