Description

Technical Field

[0001] This utility model relates to the field of industrial spraying technology, and more specifically to a coating spraying device for structural components. Background Technology

[0002] Mechanical structural components include hydraulic pumps, engines, tracks, buckets, cylinders, and working devices. Among them, the bucket is located in the direct working structure and requires multiple steps in production, including blanking, cutting, welding, final welding, shot blasting, primer coating, and topcoat spraying. After shot blasting, the bucket surface is coated with putty and ready to enter the painting workshop to begin the complete painting process. In the painting process, primer coating is a critical step. Inside the painting room, there is a water pool under the fence. The water in the pool is constantly flowing. Since a lot of dust is generated during the primer coating process, a blower is installed on the ceiling to blow air from top to bottom, ensuring that the dust can fall into the water pool and settle.

[0003] However, this type of spray booth also has certain drawbacks. In order to speed up the efficiency of the bucket primer coating, multi-angle spray guns are installed on the side wall of the spray booth. However, this also has an impact, namely, the horizontal spray guns will spray onto the other side wall, causing pollution in the spray booth and making it difficult to clean. Even if a water pool is set up below, it cannot solve the problem of the side wall being contaminated by the primer coating. Utility Model Content

[0021] The first embodiment of this utility model is as follows: A structural component coating spraying device includes a spraying chamber and a spraying component and a cleaning component installed inside the spraying chamber. The spraying chamber is a box-type structure composed of side walls 15 on both sides and a top plate 1 on the top. The front and rear ends of the spraying chamber are respectively equipped with openable and closable doors. When the bucket is hung, the doors are opened, and after the bucket enters the spraying chamber, the doors are closed to start spraying.

[0022] The spraying chamber is equipped with a water tank 10, the length of which is less than the overall length of the spraying chamber. Platforms are set at both ends of the water tank 10, allowing workers to stand on the platforms and use a lifting device to hang the bucket on the monorail crane 4. Meanwhile, the track 5 is the same length as the entire length of the spraying chamber.

[0023] The pool 10 is equipped with a grid plate higher than the bottom of the pool. The pool 10 is filled with clean water, and the height of the clean water is higher than the height of the grid plate. A liquid level sensor 9 is installed on the lower part of the right side wall 15. The sensing head of the liquid level sensor 9 extends into the pool 10 to detect the water level of the clean water in the pool 10. A side platform 11 is installed near the left side wall 15 of the pool 10. A drain pipe 12 is installed inside the side platform 11. One end of the drain pipe 12 is connected to the pool 10, and the other end of the drain pipe 12 passes through the side wall 15 and extends to the outside of the spray booth and is equipped with a valve 13. The system also includes a PLC controller for control. The PLC controller is electrically connected to the liquid level sensor 9 and the valve 13 and is used to switch the opening and closing state of the valve 13 according to the liquid level. The water discharged from the drain pipe 12 can be collected and treated through a standard wastewater treatment procedure.

[0024] A certain amount of clean water is poured into the pool 10 beforehand. Then, the water curtain can replenish the water and form a water curtain plane to wash the primer dust that floats to the side wall 15 into the pool 10. At this time, the water level in the pool 10 will rise. The water level is detected in real time by the liquid level sensor 9. When the water level is higher than the side platform 11, the valve 13 is opened to discharge the excess clean water. When the water level is close to the grid plate, the valve 13 is closed.

[0025] Meanwhile, when staff need to enter the spray booth, valve 13 is opened directly to drain the water so that the water level is lower than the grid plate. At this time, staff can enter the spray booth and stand on the grid plate.

[0026] A hard water pipe 17 is installed at the top of the left-side sidewall 15 along the extension direction of the spray chamber. Several clean water nozzles 16 are evenly installed at the lower part of the hard water pipe 17. The water mist spread angle of the nozzles is 120 to 150 degrees. A ramp 14 is installed on this sidewall 15, with a relative angle of 1 to 3 degrees between the ramp 14 and the sidewall 15. The spray angle of the nozzles is tilted towards the ramp 14. Figure 1 As shown, the water sprayed from multiple nozzles can contact the inclined plate 14 to form a complete water curtain, and flow downwards to eventually flow into the water pool 10, while simultaneously washing away the primer dust that floats to the water curtain into the water pool 10.

[0027] The spraying assembly includes a top spray gun 3 located at the top of the spraying chamber and a horizontal spray gun 7 located on the right side wall 15 of the spraying chamber. The top spray gun 3 and the horizontal spray gun 7 spray the primer to form a two-way dense spraying surface to complete the primer spraying, spraying the primer onto the bucket from two angles.

[0028] A mounting frame 2 is fixedly installed at the lower part of the top plate 1. A track 5, arranged along the extension direction of the spray booth, is installed at the lower middle position of the mounting frame 2. A monorail crane 4 is mounted on the track 5 in a relatively movable manner, and a hook is provided at the lower end of the monorail crane 4. A rotary joint is provided on the monorail crane 4, which is located between the monorail crane 4 and the hook. The monorail crane 4 is connected to the outer ring of the rotary joint, and the hook is connected to the inner core of the rotary joint. Driven by a motor, the outer ring and inner core of the rotary joint can rotate relative to each other, so that the bucket can be completely sprayed with primer. The electrical wires are arranged along the mounting frame 2 and connected to the motor. The monorail crane 4 moves on the track 5 by driving the rollers to rotate through the drive motor.

[0029] Support brackets 8 are installed on both sides of the lower part of the mounting frame 2. The top spray gun 3 is installed on the lower part of the support bracket 8. The tail of the top spray gun 3 is connected to the spray pipe 6. The spray pipe 6 passes through the inside of the mounting frame 2. The support bracket 8 is set in the middle of the right side wall 15. The horizontal spray gun 7 is installed on the left end of the support bracket 8. The tail of the horizontal spray gun 7 is connected to the spray pipe 6. A through hole is provided on the side wall 15. The spray pipes 6 at the tail ends of the top spray gun 3 and the horizontal spray gun 7 converge and are bundled at the through hole, and then pass through the through hole to the outside of the spray chamber and connect to the primer tank.

[0030] Meanwhile, there are multiple horizontal spray guns 7, which are arranged in a uniform horizontal manner. The primer is sprayed from the horizontal spray guns 7 and the top spray guns 3 through the external primer tank and pressure. The horizontal spray guns 7 and the top spray guns 3 have the same specific structure, but are installed in different positions and use standard primer spray guns on the market.

[0031] In use, the sealing door is opened and the bucket is hung on the hook by the lifting device. Then, the bucket is moved to the spraying position in the spraying chamber by the monorail crane 4. At the same time, the sealing door is closed, and the top spray gun 3 and the horizontal spray gun 7 work simultaneously. The rotary joint works to spray the bucket. The primer dust falls onto the water tank 10 and the water curtain and eventually flows into the water tank 10. At the same time, the liquid level sensor detects the water level in real time and automatically controls the valve 13 to open and close to keep the water level between the side platform 11 and the grid plate. After the spraying is completed, the sealing door is opened and the bucket is moved out of the spraying chamber by the monorail crane 4 and unloaded. After the primer dries, the next process of spraying the topcoat is carried out.
