Description

Technical Field

[0001] This utility model relates to the field of air knives, and in particular to a split-type annular air knife. Background Technology

[0002] In industrial production, some products require air-blowing equipment to move from one step to the next via conveyor systems. Air knives are one of the most commonly used air-blowing devices, widely used in industries such as printing, electronic plating, hardware, pharmaceuticals, and printed circuit boards for cooling, cleaning, liquid blowing, and drying of products.

[0003] The existing air knife has a strip structure, which is limited when blowing cylindrical products. It cannot blow air out completely, resulting in the need for multiple drying operations, which is time-consuming and labor-intensive. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a split-type annular air knife to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a split-type annular air knife, including two semi-circular cutters, which are spliced ​​together to form a complete annular air knife. Each semi-circular cutter has a connector connected to its middle part. The semi-circular cutter includes a cutter holder and a blade. The cutter holder and the blade are connected by bolts and form an air outlet on the inner edge of the connection position.

[0006] Preferably, one side of the tool holder has an arc-shaped air cavity, which is connected to the connector for conveying gas.

[0007] Preferably, the inner edge of the blade is provided with a bevel.

[0008] Preferably, the two semi-circular cutters are assembled via a connecting piece on the back.

[0009] Preferably, the width of the air outlet is 0.05 mm.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model features two semi-circular cutters joined together to form a complete ring cutter. By connecting to an air source via a connector, gas is discharged from the air outlet, creating a ring-shaped airflow that allows for all-around drying of round products. This achieves one-time drying, saving time and effort and greatly improving work efficiency. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] This utility model provides a split-type annular air knife, such as Figure 1-4 As shown, it includes two semi-circular cutters 1, which are spliced ​​together to form a complete annular air knife. Each semi-circular cutter 1 has a connector 2 connected to its middle part. The semi-circular cutter 1 includes a cutter holder 4 and a blade 5. The cutter holder 4 and the blade 5 are connected by bolts and form an air outlet 6 on the inner edge of the connection position.

[0020] Two semi-circular cutters 2 are joined together to form a complete ring cutter. The air source is connected by the connector 2, and the air is discharged from the air outlet 6, so that the airflow forms a ring, thereby drying the round product from all directions, achieving one-time drying, saving time and effort, and greatly improving work efficiency.

[0021] In this embodiment, an arc-shaped air cavity 41 is provided on one side of the knife holder 4. The air cavity 41 is connected to the connector 2 for conveying gas.

[0022] In this embodiment, the inner edge of the blade 5 is provided with a bevel 51, so that the airflow flows along the bevel 51, such as... Figure 5 As shown.

[0023] In this embodiment, the two semi-circular cutters 1 are assembled together via a connecting piece 3 on the back. The width of the air outlet 6 is 0.05mm, which reduces the width of the air outlet, thereby increasing the airflow by up to 40 times.

[0024] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.

[0025] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
