Description

Technical Field

[0001] This utility model belongs to the field of electrical distribution box spraying and drying technology, specifically a electrical distribution box spraying and drying mechanism. Background Technology

[0002] With the development of the times, people's lives are becoming increasingly inseparable from the application of electricity. The use of electricity often requires the use of distribution boxes. Distribution boxes often need to be sprayed during the production process to meet requirements such as corrosion prevention. After the spraying is completed, the distribution boxes need to be dried, so a distribution box spraying and drying mechanism is needed.

[0003] A Chinese patent with authorization announcement number CN219187469U discloses a spraying and drying mechanism for the production of electrical distribution boxes. The mechanism includes a base frame, a drying box fixedly connected to the base frame, a motor mounted on the base frame, a clamp fixedly connected to a slider, an electric heating wire installed inside the drying box, and a fixed pipe fixedly connected inside the drying box. A feed pipe is connected to the fixed pipe, one end of which passes through the drying box and extends to the outside. Multiple spray nozzles are connected to the fixed pipe. This mechanism has the effect of preventing the electrical distribution box from tipping over and avoiding damage to the electrical distribution box, and is highly practical.

[0004] However, the above solution still has some problems. The distance between the centrifugal hot air blower at the top of the drying box and the top of the distribution box cannot be adjusted. As a result, when drying distribution boxes sprayed at different heights, the drying quality of the sprayed distribution boxes is easily reduced. Therefore, in order to solve the above problems, a distribution box spraying and drying mechanism is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a power distribution box spraying and drying mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is a power distribution box spray drying mechanism, including: a base plate, on which a centrifugal hot air fan is installed, the output end of the centrifugal hot air fan extending into the interior of the base plate, a first limiting groove being formed on the base plate, a drying chamber being installed on the upper surface of the base plate, an extension plate being fixedly connected to the bottom of the drying chamber, the extension plate passing through the first limiting groove, a first limiting plate being installed at the bottom of the extension plate, drive motors being symmetrically installed on one side of the base plate, teeth being formed on both sides of the extension plate, connecting shafts being fixedly connected to the output ends of the two sets of drive motors, gears being fixedly connected to the connecting shafts, the gears meshing with the teeth, one end of the connecting shaft being rotatably connected to the interior of the base plate, and two sets of dustproof curtains being installed on one side of the drying chamber, with magnetic strips fixedly connected to the opposite sides of the two sets of dustproof curtains, the two sets of magnetic strips attracting each other, connecting the two sets of dustproof curtains, thereby sealing the drying chamber and reducing heat loss during drying.

[0007] Preferably, the base plate has symmetrically provided second limiting grooves inside, and the base plate has provided third limiting grooves inside. The third limiting groove is located between the two sets of second limiting grooves, and the third limiting plate is located in the third limiting groove, thereby cooperating with the cylinder to improve the stability of the adjusting plate when it moves.

[0008] Preferably, a cylinder is installed on one side of the base plate, the telescopic end of the cylinder extends into the interior of the base plate, and an adjustment plate is installed on the telescopic end of the cylinder. The adjustment plate has symmetrical adjustment slots. When the cylinder runs, it drives the adjustment plate to move, thereby allowing the position of the connecting rod to be adjusted through the adjustment slots.

[0009] Preferably, a connecting rod is slidably connected inside the adjusting groove, and a second limiting plate is fixedly connected to one end of the connecting rod. The second limiting plate is slidably connected inside the second limiting groove. The second limiting plate moves within the second limiting groove, thereby cooperating with the adjusting plate to ensure the stability of the second limiting plate and the connecting rod and to prevent them from slipping during movement.

[0010] Preferably, a third limiting plate is fixedly connected to the lower surface of the adjusting plate, the third limiting plate is slidably connected inside the third limiting groove, one end of the connecting rod passes through the upper surface of the base plate, and a fixing frame is fixedly connected to one end of the connecting rod. An anti-slip pad is fixedly connected to one side of the fixing frame. The anti-slip pad can increase the friction with the surface of the distribution box, thereby improving the fixing strength of the distribution box and preventing the lighter distribution box from tilting due to wind.

[0011] Preferably, the drying mechanism is connected to an external control box, which is used to control the start and stop of the drive motor, cylinder and centrifugal hot air blower. By controlling the drive motor, cylinder and centrifugal hot air blower through the external control box, the ease of use of the drying mechanism is improved.

[0012] The advantages of this utility model are: by driving the connecting shaft and gear to rotate through the drive motor, external force is applied to the gear teeth, thereby adjusting the height of the extension plate and the drying box, so that the air outlet of the centrifugal hot air blower can be at a moderate distance from the top of the distribution box of different sizes, thus avoiding uneven coating curing due to the centrifugal hot air blower being too close to the top of the distribution box, and avoiding the situation of reduced drying efficiency due to the distance being too far, thereby improving the drying quality of the sprayed distribution box.

[0013] This invention uses a cylinder to move an adjusting plate. Because the two sets of adjusting grooves are V-shaped, when the adjusting plate moves, it can drive the connecting rod to slide along the adjusting groove, thereby adjusting the distance between the two sets of fixed frames. This avoids the situation where the lighter electrical boxes are tilted due to wind problems when drying them, thus reducing manual intervention during the drying process and improving the drying efficiency of the coated electrical boxes.

[0021] 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.

[0022] Please see Figure 1-5As shown, a power distribution box spray drying mechanism includes: a base plate 1, a centrifugal hot air blower 22 installed on the base plate 1, the output end of the centrifugal hot air blower 22 extending into the interior of the base plate 1, a first limiting groove 2 opened on the base plate 1, a drying box 3 installed on the upper surface of the base plate 1, an extension plate 4 fixedly connected to the bottom of the drying box 3, the extension plate 4 passing through the first limiting groove 2, a first limiting plate 5 installed at the bottom of the extension plate 4, a drive motor 6 symmetrically installed on one side of the base plate 1, teeth 7 opened on both sides of the extension plate 4, a connecting shaft 8 fixedly connected to the output ends of the two sets of drive motors 6, a gear 9 fixedly connected to the connecting shaft 8, the gear 9 meshing with the teeth 7, one end of the connecting shaft 8 rotatably connected to the interior of the base plate 1, two sets of dustproof curtains 10 installed on one side of the drying box 3, and magnetic strips 11 fixedly connected to the opposite sides of the two sets of dustproof curtains 10.

[0023] Distribution boxes often require spraying during production to meet requirements such as corrosion resistance. After spraying, the distribution boxes need to be dried. For distribution boxes sprayed at different heights, the height of the centrifugal hot air blower 22 needs to be adjusted to improve the drying effect. Therefore, a distribution box spraying and drying mechanism is proposed. In actual use, the height of the drying chamber 3 is adjusted according to the height of the distribution box to be dried. The drive motor 6 is started via an external control box, driving the connecting shaft 8 and gear 9 to rotate. Because gear 9 meshes with teeth 7, it drives the extension plate 4 to move. Thus, the height of the drying chamber 3 can be adjusted according to the direction of rotation of gear 9. When the drying chamber 3 rises, the extension plate 4 and dustproof... The curtain 10 moves upward along the first limiting groove 2 to avoid a large gap between the drying box 3 and the base plate 1, thereby preventing heat from dissipating during drying and improving the drying quality of the sprayed electrical box. When the height of the drying box 3 is adjusted to a suitable level, the drive motor 6 is turned off through the external control box to fix the height of the drying box 3 and the centrifugal hot air blower 22. Then, the dust curtains 10 on both sides are lifted outward, and the electrical box to be dried is placed on the two sets of fixed brackets 20. The dust curtains 10 are released so that the two sets of magnetic strips 11 attract each other, thereby cooperating with the drying box 3 and reducing the heat inside the drying box 3 from dissipating outward. The centrifugal hot air blower 22 is started through the external control box to dry the sprayed electrical box.

[0024] Please see Figure 1-5As shown, a second limiting groove 12 is symmetrically formed inside the base plate 1, and a third limiting groove 13 is formed inside the base plate 1. The third limiting groove 13 is located between the two sets of second limiting grooves 12. A cylinder 14 is installed on one side of the base plate 1. The telescopic end of the cylinder 14 extends into the interior of the base plate 1. An adjusting plate 15 is installed on the telescopic end of the cylinder 14. Adjusting grooves 16 are symmetrically formed on the adjusting plate 15. A connecting rod 17 is slidably connected inside the adjusting groove 16. A second limiting plate 18 is fixedly connected to one end of the connecting rod 17. The limiting plate 18 is slidably connected inside the second limiting groove 12. The lower surface of the adjusting plate 15 is fixedly connected to the third limiting plate 19. The third limiting plate 19 is slidably connected inside the third limiting groove 13. One end of the connecting rod 17 passes through the upper surface of the base plate 1. One end of the connecting rod 17 is fixedly connected to the fixing frame 20. One side of the fixing frame 20 is fixedly connected to the anti-slip pad 21. The drying mechanism is externally connected to a control box. The external control box is used to control the start and stop of the drive motor 6, cylinder 14 and centrifugal hot air blower 22.

[0025] When drying lighter distribution boxes, the cylinder 14 is activated via an external control box according to the width of its bottom. When the output end of the cylinder 14 extends or retracts, it drives the adjusting plate 15 and the second limiting plate 18 to move along the third limiting groove 13. The connecting rod 17 is located in the adjusting groove 16. Since the adjusting groove 16 is V-shaped, when the extending end of the adjusting plate 15 retracts, the connecting rod 17 moves outward through the two sets of adjusting grooves 16, which can increase the distance between the two sets of fixing frames 20, thus clamping and fixing the wider distribution box. When the extending end of the adjusting plate 15 extends outward, the connecting rod 17 moves to a position closer to the two sets of adjusting grooves 16 through the adjusting groove 16, thus reducing the distance between the two sets of fixing frames 20, thus clamping and fixing the narrower distribution box. This can prevent the lighter distribution box from tilting due to the airflow problem of the centrifugal hot air blower 22 during drying, thereby reducing manual intervention during the drying of the distribution box and improving the drying efficiency of the coated distribution box.

[0026] Working principle: When drying electrical boxes sprayed at different heights, the drive motor 6 is started via an external control box, driving the connecting shaft 8 and gear 9 to rotate, which in turn moves the extension plate 4. The height of the drying chamber 3 can be adjusted according to the direction of gear 9's rotation. When the height of the drying chamber 3 is adjusted to the appropriate level, the drive motor 6 is turned off via the external control box, fixing the height of the drying chamber 3 and the centrifugal hot air blower 22. Then, the dust curtains 10 on both sides are opened outwards. Based on the width of the bottom of the lighter electrical box, the cylinder 14 is started via the external control box. Because the adjusting groove 16 is V-shaped, when the telescopic end of the adjusting plate 15 retracts, the two sets of connecting rods 17 move outward through the adjusting groove 16, which can increase the distance between the two sets of fixing frames 20. When the telescopic end of the adjusting plate 15 extends outward, the connecting rods 17 move to a position closer to the two sets of adjusting grooves 16 through the adjusting groove 16, thereby reducing the distance between the two sets of fixing frames 20. This allows for clamping and fixing of narrower distribution boxes. Then, the centrifugal hot air blower 22 is started through the external control box to dry the sprayed distribution box.
