Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, specifically to spray painting equipment for impellers used in fan production. Background Technology

[0002] Impellers are made of metal. To reduce oxidation and corrosion, they are painted. However, some painting equipment on the market does not fix the impeller during the painting process, causing it to move back and forth. This results in uneven painting of the impeller fan and affects its performance.

[0003] Application number CN202320193688.4 discloses impeller painting equipment for wind turbine production, relating to the field of wind turbine manufacturing technology. This impeller painting equipment for wind turbine production includes a housing, an auxiliary mechanism, and a mixing mechanism. A protective box is fixedly installed on the rear inner wall of the housing, and a paint spraying box is fixedly installed on one outer wall of the housing. A storage box is provided inside the housing. The auxiliary mechanism is located on the housing and includes a motor, a rotating rod, a first bevel gear, a second bevel gear, a fixed rod, a threaded rod, and a nut. The nut is used to fix the impeller to be painted. The motor drives the rotating rod to rotate, which in turn drives the fixed rod to rotate through the first and second bevel gears. The mixing mechanism is located on the housing and is used to mix the paint in the paint spraying box. This invention, by fixing the impeller, avoids the impeller from wobbling back and forth, which would reduce painting efficiency.

[0004] The impeller painting equipment disclosed in the aforementioned document for wind turbine production has the following defects: after painting the impeller, the paint on the impeller needs to be dried. The color requirements of the impeller during painting will also be different. Different colors of paint are prone to color bleeding when they are not dry. The equipment cannot dry the paint on impellers of different colors, and lacks flexibility.

[0005] Therefore, it can be seen that the existing impeller painting equipment does not have the function of preventing color bleeding after impellers are dyed for different painting needs. It is necessary to improve the existing equipment to provide a function that can prevent color bleeding after impellers are dyed for different painting needs. Utility Model Content

[0006] The purpose of this invention is to provide impeller painting equipment for wind turbine production, so as to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The purpose of this setup is to allow the bottom and top doors to be opened during equipment use, with the impeller placed on the upper and lower drying plates. Water from the water tank is supplied to the spray nozzles via pressurized water pipes. The water is then sprayed upwards through the nozzle holes, the water jets approaching the inner and outer walls of the iron sealing shell and baffles. The water then flows downwards through the top plate of the baffles, passing over the two drying plates. A spray gun paints the impellers on the drying plates, and a water curtain isolates and cleans the paint sprayed onto the inner walls of the equipment. After painting, the bottom door is rotated upwards to close the bottom drying plate, and then the top door is rotated to close the opening of the sealing shell. The top door is then vertically downwards to secure the bottom door. The drying status of the impellers can be observed through the viewing window. A quick-drying fan dries the impellers on the two drying plates. The drying plates are secured by a positioning frame. Sliding open the sliding plate allows the quick-drying fan to cool the heat inside the sealing shell. The rotating wheel facilitates movement of the equipment. The control components are used to control the pressure of the pressurized water pipes to adjust the water flow impact force.

[0009] Furthermore, hinges are installed on the upper and lower outer walls of one side of the sealing shell. A top door is installed on the outer wall of the top hinge, and a viewing window is provided on the inner wall of the top door. A bottom door is installed on the outer wall of the bottom hinge.

The top door is then vertically downwards to press and fix the bottom door in place, and the drying status of the impeller can be observed through the viewing window.

[0010] Furthermore, the two sets of positioning frames are respectively covered by a top door and a bottom door, with the top door located outside the bottom door. The purpose of this arrangement is that, during use of the equipment, the bottom door rotates upwards to close the bottom drying plate, while the top door vertically downwards to secure the bottom door.

[0011] Furthermore, a fixed platform is welded to the lower surface of the sealing shell, and a baffle is welded to the upper surface of the fixed platform. The baffle is located on one outer wall of the two sets of positioning frames, and a control component is provided on the front of the fixed platform. The purpose of this arrangement is that during the use of the equipment, the water column rises close to the inner and outer walls of the iron sealing shell and the baffle, and the water flows downward through the top plate of the baffle and passes through the two sets of drying plates.

[0012] Furthermore, the mobile assembly includes a base frame with four wheels mounted on its bottom surface. These four wheels are located at the four corners of the base frame. A water tank is located on one side of the bottom of the base frame, and a pressure water pipe is located on one side of the water tank. The pressure water pipe extends upwards through the fixed platform and the baffle. This arrangement is intended to ensure that, during operation, the water tank delivers water to the spray nozzle via the pressure water pipe.

[0013] Furthermore, a spray nozzle is installed at the top of the pressure water pipe, and the spray nozzle is installed on the side of the baffle away from the positioning frame. The purpose of this arrangement is that during the use of the equipment, water is sprayed upward through the holes of the spray nozzle, and the water column rises close to the inner and outer walls of the iron sealing shell and the baffle. The water then flows downward through the top plate of the baffle and passes through the two sets of drying plates.
