Description

Technical Field

[0001] This invention relates to the field of cleaning and drying equipment, and in particular to a reciprocating bidirectional air-cutting drying mechanism. Background Technology

[0002] To clean the workpieces, an industrial cleaning machine is required, and after cleaning, air-drying is performed to remove moisture from the workpiece surface.

[0003] The air knife operates in a fixed manner. Water is cut and dried by the movement of the workpiece as it passes the air knife's outlet, or by the movement of the air knife via a cylinder for drying stationary workpieces. However, the airflow direction at the air knife's outlet remains constant. When the air knife's outlet passes the top of the workpiece, only the airflow perpendicular to the top surface can be used for drying the top, making it difficult to reach the sides of the workpiece. This requires improvement. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a reciprocating bidirectional air-cutting and drying mechanism to achieve air-cutting and drying of the top surface and both sides of the workpiece, thereby improving the effect of water cutting and drying.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a reciprocating bidirectional air-cutting drying mechanism is provided, comprising: an air knife, a guide rail, a slide block, a rotating shaft, a flip plate, a reciprocating drive device, and a first pin seat. Two guide rails are distributed parallel to each other on the left and right. The slide block is slidably disposed above the guide rails. The rotating shaft is rotatably disposed between the two slide blocks on both sides. The flip plate is disposed on the rotating shaft. The first pin seat is disposed on the outside of the flip plate. The air knife is disposed on the top or bottom of the flip plate. A second pin seat is disposed on the side of the flip plate facing the first pin seat. The reciprocating drive device is rotatably disposed on the first pin seat, and the end of the reciprocating drive device is movably connected to the second pin seat. Limiting rods are disposed between the two slide blocks on both sides of the flip plate.

[0006] In a preferred embodiment of the present invention, the bottom of the slide block is provided with a slider located on the guide rail.

[0007] In a preferred embodiment of the present invention, the slide is provided with a bearing corresponding to the end of the rotating shaft.

[0008] In a preferred embodiment of the present invention, the reciprocating drive device is a linear telescopic cylinder.

[0009] In a preferred embodiment of the present invention, when the reciprocating drive device extends and retracts, it drives the flap to flip in the corresponding direction, uses a limiting rod to limit the flip angle of the flap, adjusts the direction of the air knife, and drives the air knife to move linearly along the guide rail.

[0010] In a preferred embodiment of the present invention, the slide is provided with waist holes on both sides of the end of the rotating shaft, and the end of the limiting rod is located in the waist holes.

[0011] In a preferred embodiment of the present invention, a limiting screw is horizontally arranged on the outer side of the slide block, pointing into the waist hole, and a spring is arranged in the waist hole on the side of the limiting rod away from the limiting screw.

[0012] The beneficial effects of the present invention are as follows: The reciprocating bidirectional air-cutting drying mechanism of the present invention drives the flap to move forward and backward through the extension and retraction of the reciprocating drive device, and switches the angle of the flap during the forward and backward movement, so that the direction of the air knife changes during the reciprocating movement, thereby realizing the air-cutting and drying of the top surface and two sides of the workpiece, improving the effect of cutting and drying, with a compact structure, flexible adjustment of the air knife angle limitation, and low operation and maintenance costs.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-3 The embodiments of the present invention include:

[0019] like Figure 1The reciprocating bidirectional air-cutting drying mechanism shown includes: air knife 7, guide rail 8, slide 9, rotating shaft 1, flip plate 4, reciprocating drive device 6 and first pin seat 11. The two guide rails 8 are distributed parallel to each other on the left and right. The guide rails 8 can be fixed in the air-cutting groove of the cleaning machine by bolts, and the structure is stable.

[0020] The slide block 9 is slidably disposed above the guide rail 8. In this embodiment, a slider 14 located on the guide rail 8 is provided at the bottom of the slide block 9. The smoothness of the slide block 9 is improved by the cooperation between the guide rail 8 and the slider 14.

[0021] like Figure 1 As shown, the rotating shaft 1 is rotatably mounted between the two sliding blocks 9. In this embodiment, the sliding blocks 9 are provided with bearings 13 corresponding to the ends of the rotating shaft 1, which improves the rotational flexibility of the rotating shaft 1. The flip plate 4 is mounted on the rotating shaft 1. A through hole can be machined in the flip plate 4 so that the rotating shaft 1 passes through the through hole and is locked with screws, so that the flip plate 4 can be flipped synchronously with the rotating shaft 1.

[0022] The air knife 7 can be set at the top or bottom of the flip plate 4, and the direction of the air knife 7 can be adjusted as the flip plate 4 flips. In this embodiment, the air knife 7 is set at the bottom of the flip plate 4, which can cut water and dry the workpiece below.

[0023] The first pin seat 11 is set on the outside of the flap 4, such as... Figure 1 As shown, the first pin seat 11 is a certain distance away from the flip plate 4 and does not contact it. A second pin seat 12 is provided on the side of the flip plate 4 facing the first pin seat 11. The reciprocating drive device 6 is rotatably mounted on the first pin seat 11, and the end of the reciprocating drive device 6 is movably connected to the second pin seat 12 to drive the flip plate 4 to flip. After the flip plate 4 flips at a certain angle, the flip plate 4 and the slide 9 move linearly in sync.

[0024] In this embodiment, the reciprocating drive device 6 uses a linear telescopic cylinder, which can be controlled by a PLC and a solenoid valve to achieve automatic extension and retraction. Limiting rods 5 are located on both sides of the flip plate 4 between the two sliding blocks 9 to limit the movement of the flip plate 4. Figure 2 and Figure 3 As shown, when the reciprocating drive device 6 extends and retracts, it drives the flip plate 4 to flip in the corresponding direction. The flip plate 4 is limited by the limit rod 5, which switches the direction of the air knife 7 and drives the flip plate 4 and the air knife 7 to move linearly along the guide rail 8, so as to realize the air knife 7 to air-cut and dry the top surface and two sides of the workpiece.

[0025] To limit and adjust the flip angle of the air knife 7, the slide 9 is provided with waist holes 3 on both sides of the end of the rotating shaft 1. The end of the limiting rod 5 is located in the waist holes 5, which facilitates the lateral adjustment of the limiting rod 5 and changes the distance between it and the rotating shaft 1. In this embodiment, a limiting screw 2 pointing into the waist hole 5 is horizontally provided on the outer side of the slide 9. A spring 10 is provided in the waist hole 3 on the side of the limiting rod away from the limiting screw. The slide 9 is provided with a threaded hole corresponding to the limiting screw 2. By rotating the limiting screw 2 and cooperating with the spring 10, the lateral adjustment of the limiting rod 5 is performed, changing the limitation on the flip angle of the flap 4 and adjusting the direction of the reciprocating movement of the air knife 7.

[0026] In summary, the reciprocating bidirectional air-cutting drying mechanism disclosed in this invention can move back and forth and switch the air knife angle bidirectionally. It can achieve air-cutting drying of the top surface and both sides of the workpiece using a single air knife, thereby reducing costs and improving the air-cutting drying effect.

[0027] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
