Description

Technical Field

[0001] This utility model belongs to the field of automotive parts spraying technology, specifically relating to a spraying device for die-cast automotive controller housings. Background Technology

[0002] In the automotive manufacturing industry, the production of the vehicle controller housing is a crucial step. The controller housing typically requires a certain level of protection and aesthetics, which necessitates a painting process after manufacturing.

[0003] The existing coating equipment for die-cast automotive controller housings lacks lifting and moving functions in its coating pipe, making it difficult to adapt to the coating needs of different positions on the die-cast parts. This results in a limited coating range and incomplete coverage. Furthermore, the liquid storage tank is not equipped with a paint stirring mechanism, which makes the paint prone to sedimentation when left to stand, affecting the stability of the coating quality. In addition, the existing equipment lacks a drying function, and the paint relies on natural air drying after coating, which is slow. This not only makes it inconvenient to remove the material but also seriously restricts the continuity of subsequent coating operations, reducing the efficiency of the equipment. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a coating device for die-cast parts of automotive controller housings, which has the characteristics of a wide coating range for die-cast parts and rapid air drying after coating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for die-cast parts of an automotive controller housing, comprising a housing, a door hinged to the front end of the housing, a mesh plate fixedly installed at the lower end of the housing, a sludge storage tank opened on the lower side of the mesh plate, a drain pipe installed at the lower end of the housing corresponding to the sludge storage tank, a horizontal plate fixedly connected to the upper side of one end of the housing, a liquid storage tank fixedly installed at the upper end of the horizontal plate, an annular pipe I provided on the upper side of the housing, a plurality of spray nozzles equidistantly installed on the inner side of the annular pipe I, a pump body installed on one side of the upper end of the housing, a suction pipe connected to one end of the pump body, the end of the suction pipe away from the pump body extending into the liquid storage tank, the other end of the pump body connected to the annular pipe I through a corrugated pipe I, a fixed box fixedly installed on one side of the upper end of the housing corresponding to the position of the annular pipe I, a motor I installed at the middle position of the upper end of the fixed box, a screw connected to the output end of the motor I, a sliding plate threadedly connected to the surface of the screw, and a sliding plate fixedly connected to the annular pipe I through a sliding rod.

[0006] Preferably, a second annular pipe is provided on the lower side of the first annular pipe, and the second annular pipe is fixedly connected to the first annular pipe by a connecting column. Several air outlet pipes are installed at equal intervals on the inner side of the second annular pipe, and a one-way valve is installed inside the air outlet pipe. A hot air blower is installed at the upper end of the box corresponding to the position of the second annular pipe, and the hot air blower is connected to the second annular pipe by a corrugated pipe.

[0007] Preferably, a second motor is installed on one side of the upper end of the liquid storage tank, and a main rod is driven to the output end of the second motor. A secondary rod is arranged parallel to one side of the main rod. Both the lower ends of the secondary rod and the main rod are fixed with pulleys, and the two pulleys are connected by a connecting belt. Spiral blades are fixedly installed on the main rod and the secondary rod inside the liquid storage tank.

[0008] Preferably, a sliding hole adapted to the slide rod is provided on one side of the upper end of the box, the side of the slide rod is tightly fitted with the inner wall of the sliding hole, the screw is rotatably connected to the box through a bearing, and a threaded hole adapted to the screw is provided inside the slide plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes the cooperation of a sliding rod and a screw to allow the first annular pipe to be flexibly raised and lowered. After the die-cast part is placed behind the mesh plate, the pump body draws the paint liquid from the storage tank and sends it to the first annular pipe through the first corrugated pipe. The spray head sprays the paint evenly, and excess paint liquid flows into the sludge storage tank, expanding the spray coverage area. After spraying, the first annular pipe moves upward and is linked to the second annular pipe. The hot air blower delivers hot air through the air outlet pipe to dry the paint liquid, avoiding the drawbacks of natural air drying and improving work efficiency. The one-way valve can prevent the paint liquid from flowing back into the second annular pipe.

[0012] 2. This utility model, by setting up an annular pipe II, synchronously starts motor II during operation, driving the main rod to rotate. The main rod drives the auxiliary rod to rotate synchronously through the transmission action of the pulley and connecting belt. The spiral blades on the main rod and auxiliary rod rotate accordingly, which fully stirs the paint liquid in the storage tank, prevents the paint liquid from settling and sedimentation, and ensures stable and uniform spraying quality.

[0014] 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 protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides the following technical solution: a spraying device for die-cast parts of an automotive controller housing, including a box body 1, a door 3 hinged to the front end of the box body 1, a mesh plate 2 fixedly installed at the lower end of the inside of the box body 1, a sludge storage tank 11 opened on the lower side of the mesh plate 2, a drain pipe 12 installed at the lower end of the box body 1 corresponding to the position of the sludge storage tank 11, a horizontal plate 10 fixedly connected to the upper side of one end of the box body 1, a liquid storage tank 4 fixedly installed at the upper end of the horizontal plate 10, an annular pipe 6 provided on the upper side of the inside of the box body 1, and a plurality of spray nozzles 29 equidistantly installed on the inner side of the annular pipe 6. A pump body 5 is installed on one side of the upper end. One end of the pump body 5 is connected to a liquid extraction pipe 14. The end of the liquid extraction pipe 14 away from the pump body 5 extends into the liquid storage tank 4. The other end of the pump body 5 is connected to the annular pipe 6 through a corrugated pipe 15. A fixed box 8 is fixedly installed on one side of the upper end of the box 1, corresponding to the position of the annular pipe 6. A motor 16 is installed in the middle of the upper end of the fixed box 8. The output end of the motor 16 is connected to a screw 17. A sliding plate 18 is threaded on the surface of the screw 17. The sliding plate 18 is fixedly connected to the annular pipe 6 through a sliding rod 19.

[0016] Specifically, a second annular pipe 9 is provided on the lower side of the first annular pipe 6. The second annular pipe 9 is fixedly connected to the first annular pipe 6 by a connecting column 26. Several air outlet pipes 28 are installed at equal intervals on the inner side of the second annular pipe 9. A one-way valve 13 is installed inside the air outlet pipe 28. A hot air blower 7 is installed at the upper end of the housing 1 corresponding to the position of the second annular pipe 9. The hot air blower 7 is connected to the second annular pipe 9 by a corrugated pipe 27.

[0017] By adopting the above technical solution, after the spraying is completed, the motor 16 drives the screw 17 to reverse, which drives the annular tube 6 to move upward. The annular tube 6 moves upward synchronously through the connecting column 26 and the annular tube 9. At this time, the hot air fan 7 is started, and the hot air is sent into the annular tube 9 through the corrugated pipe 27. Then, it is blown onto the die-casting part through several air outlet pipes 28 on its inner side, which quickly dries the surface paint. This avoids the inconvenience of material handling caused by the slow natural air drying rate and the restriction on the continuity of subsequent spraying operations, which significantly improves the working efficiency of the device. The one-way valve 13 in the air outlet pipe 28 can effectively prevent the paint from flowing back into the annular tube 9 during the spraying process.

[0018] Specifically, a second motor 20 is installed on one side of the upper end of the liquid storage tank 4. The output end of the second motor 20 is connected to a main rod 21. A secondary rod 22 is arranged parallel to one side of the main rod 21. Pulleys 24 are fixed at the lower ends of both the secondary rod 22 and the main rod 21. The two pulleys 24 are connected by a connecting belt 25. Spiral blades 23 are fixedly installed on both the main rod 21 and the secondary rod 22 inside the liquid storage tank 4.

[0019] By adopting the above technical solution, the motor 20 is started synchronously during operation, driving the main rod 21 to rotate. The main rod 21 drives the auxiliary rod 22 to rotate synchronously through the transmission action of the pulley 24 and the connecting belt 25. The spiral blades 23 on the main rod 21 and the auxiliary rod 22 rotate accordingly, which fully stirs the paint liquid in the storage tank 4, prevents the paint liquid from settling and sedimentation, and ensures stable and uniform spraying quality.

[0020] Specifically, a sliding hole adapted to slide rod 19 is provided on one side of the upper end of the housing 1. The side of slide rod 19 is tightly fitted with the inner wall of the sliding hole. Screw 17 is rotatably connected to housing 1 through bearing. Threaded hole adapted to screw 17 is provided inside slide plate 18.

[0021] By adopting the above technical solution, the slide bar 19 can slide on the upper end of the housing 1, and the rotation of the screw 17 can drive the slide plate 18 to move.

[0022] Specifically, a transparent observation window is embedded at one end of the liquid storage tank 4, and an injection pipe is fixedly installed on one side of the upper end of the liquid storage tank 4. The side of the corrugated pipe 27 is offset from the side of the annular pipe 6.

[0023] By adopting the above technical solutions, the transparent observation window facilitates real-time monitoring of the remaining paint level, the injection pipe allows for timely replenishment, and the staggered arrangement of the corrugated pipe 27 and the annular pipe 6 avoids interference between their movements, ensuring smooth lifting and drying operations.

[0024] Specifically, the spiral blades 23 on the main rod 21 and the auxiliary rod 22 are staggered, and the spiral blades 23 on the main rod 21 and the auxiliary rod 22 are staggered from the liquid extraction tube 14.

[0025] By adopting the above technical solution, the rubbing and impact between the spiral blades 23 on the main rod 21 and the auxiliary rod 22 are avoided, and the rotation of the spiral blades 23 on the main rod 21 and the auxiliary rod 22 will not rub against the liquid extraction tube 14.

[0026] The working principle and usage process of this utility model: When using the automotive controller housing die-casting part spraying device, install the device in a suitable position, place the die-casting part to be sprayed on the mesh plate 2 inside the box 1, close the box door 3 and start the pump body 5 to draw the paint liquid from the storage tank 4 through the liquid extraction pipe 14. The paint liquid is transported to the annular pipe 6 through the corrugated pipe 15. At the same time, start the motor 16 to drive the screw 17 to rotate, which drives the slide plate 18 to move down in the fixed box 8. The slide plate 18 pushes the annular pipe 6 to move down synchronously through the slide rod 19. The spray head 29 on the inner side of the annular pipe 6 sprays the paint liquid evenly onto the die-casting part. The excess paint liquid dripping down passes through the mesh plate 2 and flows into the sludge storage tank 11. With the help of the cooperation of the slide rod 19 and the screw 17, the annular pipe 6 can be flexibly raised and lowered to achieve comprehensive spraying of the die-casting part at different height positions, effectively expanding the spraying coverage area.

[0027] After the spraying is completed, the motor 16 drives the screw 17 to reverse, which drives the annular tube 6 to move upward. The annular tube 6 moves upward synchronously through the connecting column 26 and the annular tube 9. At this time, the hot air fan 7 is started. The hot air is sent into the annular tube 9 through the corrugated pipe 27, and then blown onto the die-casting part through several air outlet pipes 28 inside it, which quickly dries the surface paint. This avoids the inconvenience of material handling caused by the slow natural air drying rate and the restriction on the continuity of subsequent spraying operations, which significantly improves the working efficiency of the device. The one-way valve 13 in the air outlet pipe 28 can effectively prevent the paint from flowing back into the annular tube 9 during the spraying process.

[0028] During operation, motor 20 is started synchronously to drive the main rod 21 to rotate. The main rod 21 drives the auxiliary rod 22 to rotate synchronously through the transmission action of pulley 24 and connecting belt 25. The spiral blades 23 on the main rod 21 and auxiliary rod 22 rotate accordingly to fully stir the paint in the liquid storage tank 4, prevent the paint from settling and sedimentation, and ensure stable and uniform spraying quality.
