Description

Technical Field

[0001] This utility model relates to the field of painting equipment technology, and in particular to a painting equipment for processing aluminum wind turbine blades that can be dried simultaneously. Background Technology

[0002] In the field of wind power equipment manufacturing, aluminum wind turbine blades are core components, and the surface coating quality directly affects the durability and power generation efficiency of the equipment. In traditional spraying processes, the painting and drying processes are usually completed in separate steps using independent equipment, which results in problems such as low process connection efficiency and unstable paint film quality. According to industry survey data, the market size of coating equipment in my country has reached RMB 158.5 billion, of which the market size of spraying robots has exceeded RMB 35 billion. However, there is still a technological gap in integrated spraying equipment for large and complex components.

[0003] A painting device for wind turbine blade processing and production, disclosed in announcement number CN112317214A, includes a housing, a base plate, a wheel groove, a heater, a motor, a drive gear, a support plate, a wheel frame, a wheel, and a U-shaped frame. The base plate is fixedly connected to the bottom inner side of the housing. A wheel groove is formed on the base plate. A heater and a motor are fixedly installed at the upper end of the base plate. A drive gear is fixedly installed at the end of the motor's output shaft. A driven gear meshes with the left side of the drive gear. A wheel frame is fixedly connected to the lower end of the support plate. A wheel is hinged within the wheel frame and located within the wheel groove. A U-shaped frame is fixedly connected to the lower end of the support plate, and a locating pin is threaded into the U-shaped frame. This invention relates to a painting device for wind turbine blade processing and production, characterized by high painting efficiency and low paint mist hazard.

[0004] The existing technology described above uses multiple nozzles to paint aluminum wind turbine blades. However, during this process, the nozzle positions are fixed, and there are gaps between the nozzles. This results in relatively less paint being sprayed in the gaps between the coverage areas of adjacent nozzles, leading to uneven paint film thickness. This affects the overall appearance quality of the aluminum wind turbine blades, potentially causing lighter colors or inconsistent gloss levels in the gaps, creating a significant difference from the areas covered by the nozzles. Furthermore, there may be paint leaks. The presence of leaked areas greatly reduces the overall protective performance of the aluminum wind turbine blades. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a painting device for processing aluminum wind turbine blades that can simultaneously dry the paint, so as to solve the problems of uneven painting and low efficiency of existing painting devices for processing aluminum wind turbine blades mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a painting device for processing aluminum wind turbine blades that can be dried simultaneously, comprising a painting box and a drive chamber, wherein a door is movably connected to the outside of the painting box, and a drive chamber is provided at the bottom of the inside of the painting box;

[0007] The drive chamber is equipped with a transmission mechanism, and a rotating disk is connected to the top of the transmission mechanism. Fixed components are connected to both sides of the top of the rotating disk, and guide wheels are connected to both sides of the bottom of the rotating disk. A rotating groove is provided at the bottom of the inside of the paint spray box, and the guide wheels rotate in the rotating groove. One-way lead screws are connected to both sides of the inside of the paint spray box, and threaded blocks are threaded to the outer side of the one-way lead screws. A paint pipe is connected to one side of each threaded block, and paint outlets are evenly connected to the outer side of each paint pipe. A conveying pipe is connected to one side of the top of each paint pipe, and one end of each conveying pipe is connected to an external paint supply device. A drying swing mechanism is provided on both sides of the top of the paint spray box.

[0008] Furthermore, the transmission mechanism includes a geared motor, which is located inside the paint spray box. The output shaft of the geared motor is connected to the main shaft through a reducer, and the drive cavities on both sides of the main shaft are respectively connected to a secondary shaft one and a secondary shaft two. The secondary shaft one and the secondary shaft two are respectively connected to the main shaft by a transmission component one and a transmission component two.

[0009] Furthermore, both transmission component one and transmission component two include pulleys and transmission belts. The pulleys are respectively sleeved on the main shaft, the first auxiliary shaft, and the second auxiliary shaft. The main shaft has two pulleys sleeved on it, and each pulley is connected to a transmission belt.

[0010] Furthermore, the top end of the main shaft is connected to the bottom end of the rotating disk, and one end of each of the secondary shafts is connected to the bottom end of the one-way lead screw. A slider is connected to one side of the threaded block on the one-way lead screw, and the slider slides on the inner wall of the paint spray box.

[0011] Furthermore, the fixing component includes a fixing plate, a push screw, and a fixing block. The fixing plate is fixed to the top of the rotating disk, and the push screw is threadedly connected inside the fixing plate. One end of the push screw is rotatably connected to the fixing plate.

[0012] Furthermore, the drying oscillation mechanism includes a drive motor, which is fixed to the top of the paint spray box by a support block. The output shaft of the drive motor is connected to a power shaft, and a power disk is fixed to one end of the power shaft. A power column is fixed to one end of the power disk, and a driven block is sleeved on the outside of the power column. The driven block is provided with a movable groove.

[0013] Furthermore, the driven block is connected to a wind plate at its bottom end, and the wind plate is evenly provided with air holes. The air holes are evenly distributed on the wind plate, and a hinge seat is connected to the outside of the wind plate, and the hinge seat is fixed to the top of the paint spray box.

[0014] Each of the air panels is connected to a drying air duct on one side, and one end of each drying air duct extends to the outside of the paint spray box and is connected to the drying equipment.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the paint spraying head of the aluminum wind turbine blade processing spraying device that can be dried simultaneously can be adjusted up and down to ensure the uniformity and comprehensiveness of the paint spraying, and it also has a drying effect, so that the paint dries quickly;

[0016] The aluminum wind turbine blades are limited by a fixed component, and the rotating disk rotates in both directions under the drive of the geared motor. The one-way screw rotates, and the one-way screw engages with the threaded block, which causes the threaded block, paint tube, and paint outlet to move up and down to spray paint on the aluminum wind turbine blades. The distance between the paint outlet and various parts of the blade surface can be dynamically adjusted to ensure that the paint mist can evenly cover the blade surface throughout the entire painting process, making the paint layer thickness more uniform and thus improving the painting quality.

[0017] The geared motor drives the main shaft to rotate, causing the rotating disk to rotate and the guide wheel to rotate in a circular motion in the rotating groove. This limits and guides the rotation of the rotating disk, allowing the aluminum impeller blades to rotate. This effectively achieves all-round coverage of the paint, avoiding the problem of local paint layer loss or insufficient protection caused by blind spots in the spraying.

[0018] Hot air is introduced into the air plate through the drying air duct and sprayed evenly through multiple air holes to efficiently dry the painted aluminum wind turbine blades, achieve paint curing, and ensure paint quality.

[0019] During the air drying process, the drive motor drives the power shaft, power disc, and power column to rotate. By cooperating with the movable slot, the air vane can swing back and forth to expand the coverage of hot air and greatly increase the contact area between the hot air and the blade surface. Furthermore, the swinging of the air vane can continuously change the blowing direction of the hot air, ensuring that both the raised and recessed parts of the blades receive sufficient hot air, thereby obtaining a uniform paint layer quality.
