Description

Technical Field

[0001] This utility model relates to the field of racket processing technology, specifically to a spraying device for racket processing and production. Background Technology

[0002] Sports are various activities that have been gradually developed in the process of human development to consciously cultivate one's physical fitness. They take various forms of physical activity such as walking, running, jumping, throwing, and dancing. These activities are what people usually call physical exercise. They are rich in content and include a variety of sports such as track and field, ball games, swimming, martial arts, aerobics, mountain climbing, skating, weightlifting, wrestling, judo, and cycling. A racket is a paddle used to play ball.

[0003] Chinese Patent Publication No. CN218340177U discloses a "Racquet Spraying Device," comprising a dustproof outer casing. The dustproof outer casing has exhaust shells installed on both the upper and lower sides at the inlet. Fixed side plates are installed on the front and rear sides inside the exhaust shells. An impeller is installed between two of the fixed side plates. A drive mechanism is located inside the exhaust shell on the side outside the fixed side plates, and the output end of the drive mechanism is fixedly connected to the fixed side plates. An inner door panel is slidably installed inside the dustproof outer casing near the inlet. A moving mechanism is installed on the lower side of the dustproof outer casing. A rotating mechanism is installed on the upper side of the moving mechanism. A clamping mechanism is installed on the outer side of the rotating mechanism. The impeller rotation generates airflow to remove dust from the racket and dustproof outer casing, thereby preventing dust from affecting the spraying process.

[0004] While existing technologies can coat rackets, they lack adjustable support devices for rackets of different sizes, limiting their applicability and flexibility. Furthermore, the racket cannot be stably held in the intended position during coating, leading to uneven paint application, missed areas, or overcoating, affecting the racket's appearance and performance. Additionally, the relatively limited coating angle prevents even coverage of the racket surface, potentially resulting in missed areas or insufficient coating. Utility Model Content

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] First, this utility model involves fitting the racket to be painted into the inner support grooves inside multiple inner support blocks. By activating the cylinder inside the inner support column, the cylinder drives the telescopic column upwards. The movement of the telescopic column moves the fixedly connected push-pull plate, which in turn moves the push-pull block. The movement of the push-pull block, via a push-pull rod, moves the power plate. The power plate, through a fifth connecting column and a fifth fixed block, pushes the inner support block outwards. The outer surface of the inner support column is connected to a first fixed block and a third fixed block. The first fixed block is connected to a first connecting plate via a first connecting column. The first connecting plate is connected to a second fixed block via a second connecting column. The second fixed block is connected to the inner support block. The first fixed block is connected to the second fixed block via the first connecting plate. The third fixed block... The third connecting column connects to the second connecting plate, which in turn connects to the fourth fixing block via the fourth connecting column. The fourth fixing block is connected to the inner support block, and the third fixing block connects to the fourth fixing block via the second connecting plate. The first and second connecting plates connect the inner support column and the inner support block, providing support and limiting for the inner support block. Multiple power plates fix the racket to be painted inside the inner support groove. The inner support column connects to a moving rod via a fixed plate. The moving rod is slidably embedded inside the connecting rod and can not only slide inside the connecting rod but also rotate inside it. Rotating the moving rod causes the support frame to rotate, placing the racket to be painted above the paint spraying groove. Through the above technical solution, the support and fixation of different types of rackets are completed.

[0017] Secondly, this utility model utilizes a micro motor located inside the support frame. The output shaft of the micro motor is connected to a threaded rod. A threaded block is threaded onto the outer surface of the threaded rod, and the threaded block is connected to a hydraulic base.

The rotating plate is connected to the fixed plate via the internal rotating column, and the fixed plate is fixedly connected to a paint sprayer. The booster contains a liquid delivery pipe, the other side of which is inside the paint sprayer. Paint is sprayed out through the spray nozzle inside the paint sprayer. When painting is required, the micro motor drives multiple paint sprayers to move. The height of the paint sprayers is adjusted by the hydraulic rod. During painting, the angle of the paint sprayer can be adjusted by rotating the hand-held handle, or by rotating the moving rod or the support frame to adjust the angle of the racket and the paint surface.
