[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1 and 2 , embodiments of the present invention include:

[0021] like Figure 1 The wind shear drying mechanism for the cleaning machine shown includes: a drying box 1 and a wind shear assembly 2. The wind shear assembly 2 is rotatably arranged in the drying box 1. The wind shear assembly 2 includes a sealing plate 23, a first air distribution pipe 21 and a second air distribution pipe 22. The first air distribution pipe 21 is eccentrically arranged in the second air distribution pipe 22. The sealing plate 23 is arranged at both ends of the first air distribution pipe 21 and the second air distribution pipe 22, and can be welded to seal both ends of the first air distribution pipe 21 and the second air distribution pipe 22 to improve air tightness and structural stability.

[0022] To facilitate the movement of workpieces into and out of the drying oven 1, the wind shear assembly 2 is located on one side of the inner wall of the drying oven 1. A turntable 5 is provided within the drying oven 1. The turntable 5 is connected to a sealing plate at one end of the wind shear assembly 2, driving the rotation of the wind shear assembly 2. In this embodiment, a motor driving the turntable 5 is provided on the outer wall of the drying oven 1. This motor can be controlled by a PLC, enhancing the level of automation.

[0023] The wind shear assembly 2 can be positioned horizontally or vertically within the drying oven 1 to accommodate various usage requirements. An air inlet connector, connected to the first air distribution pipe 21, is located on the outer circumference of the second air distribution pipe 22 or on the sealing plate at one end of the wind shear assembly 2. This connector can be connected to an external compressed air line to deliver compressed air to the first air distribution pipe 21. As workpieces enter and exit the drying oven 1, the wind shear assembly 2 allows for multiple twisting and swinging, multi-angle wind shear drying, significantly improving drying effectiveness and efficiency.

[0024] A notch 24 extending along the length of the first air distribution pipe 21 is provided on one side of the second air distribution pipe 22 close to the first air distribution pipe 21 . A baffle 28 extending to the first air distribution pipe 21 is provided on one side of the notch 24 for partial blocking.

[0025] like Figure 2 As shown, a first guide plate 27 extending outward is provided on the other side of the slot 24, and a second guide plate 26 extending outward through the slot 24 and parallel to the first guide plate 27 is provided on the first air distribution pipe 21. In this embodiment, the distance between the first guide plate 27 and the second guide plate 26 is 0.3 to 2 mm, forming a narrow gap for air outlet.

[0026] The inner wall of the baffle 28, the outer wall of the first air distribution pipe 21, the inner wall of the second air distribution pipe 22, the inner wall of the first guide plate 27 and the inner wall of the second guide plate 26 form a cavity 25 with an opening located between the first guide plate 27 and the second guide plate 26. From a cross-sectional view, the eccentricity of the first air distribution pipe 21 in the second air distribution pipe 22 forms a crescent-shaped cavity 25. The space at the upper and lower ends of the cavity 25 is small, while the middle is large. In addition, the outer circle of the first air distribution pipe 21 near the baffle is provided with a spaced-apart space. The air hole 29 connected to the cavity 25 first sends the compressed air in the first air distribution pipe 21 into the lower part of the cavity 25. During the counterclockwise flow of the compressed air from the lower part of the cavity 25, it first passes through the area with enlarged cross-section in the middle part of the cavity 25, and then passes through the area with reduced cross-section in the upper part of the cavity 25. This is beneficial to the uniform distribution of the airflow in the cavity 25, and can also guide the spiral flow of the airflow, accelerating the ejection from the opening between the first guide plate 27 and the second guide plate 26, thereby improving the effect of wind shear drying.

[0027] In this embodiment, the air holes 29 are spaced apart along the length of the first air distribution pipe 21. The compressed air in the first air distribution pipe 21 enters the cavity 25 through the plurality of air holes 29 at the same time, and is uniformly mixed by the crescent-shaped cavity 25. Figure 2 As shown, the second guide plate 26 is tangent to the outer circle of the first air distribution pipe 21 to reduce the resistance of the air flow out.

[0028] A drain valve 4 is provided at the bottom of the drying box 1. Opening this valve facilitates drainage. In this embodiment, a non-woven fabric 3 is provided on the inner wall of the drying box 1 opposite the opening of the cavity 25. This non-woven fabric 3 receives the water-laden airflow, reducing splashing and rewetting of the workpiece. Furthermore, the water in the non-woven fabric 3 flows downward to the bottom of the inner cavity of the drying box 1.

[0029] In summary, the present invention provides an air shear drying mechanism for a cleaning machine, in which the workpiece enters and exits the drying box at one time, and the air shear assembly can perform air shear drying of the workpiece at multiple angles and frequencies, thereby improving the drying efficiency and effect.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
