Description

Technical Field

[0001] The utility model relates to the field of cutting mechanisms, in particular to a multi-angle rotary cutting mechanism for flexible pipes. Background Art

[0002] As a widely used pipeline product, the hose plays an important role in modern industrial and civil fields. It is mainly used for the transportation of gases, liquids, and steam. The application fields of hoses are very extensive, covering almost all industries such as industry, construction, medical, food, agriculture, automotive, and aviation. For example, in the industrial manufacturing process, hoses are often used to transport various fluid media such as gases, liquids, and steam; as wire, cable, and electrical wire and cable protection pipes for automated instrument signals; in the building water supply and drainage system, hoses can be used to connect water-using devices such as faucets, showers, and washing machines; in the food processing process, hoses can be used to transport various food raw materials and finished products, and can also be used for straws, etc. At the same time, it can also be used as...

[0003] A hose cutting machine is a mechanical device specifically used for cutting hoses. It is mainly used to cut hoses of different specifications and materials into segments of specified lengths. A hose cutting machine usually includes a cutting mechanism, a conveying mechanism, and a feeding component. The conveying mechanism is responsible for transporting the hose to be cut from the starting position to below the cutting mechanism and transporting the cut hose segments out of the machine after cutting. The feeding component is the part of the hose cutting machine used to feed the hose into the cutting area and usually works in coordination with the conveying mechanism. The cutting mechanism is the core component of the hose cutting machine and is responsible for performing the cutting action. Under the control of the controller, the cutting mechanism works to cut the hose. During the cutting process, sensors may be used to detect the position and length of the hose to ensure the accuracy of cutting.

[0004] The cutting mechanism of existing hose cutting machines usually includes a cutting knife, a lifting cylinder, and a fixing frame. The cutting knife is connected to the fixing frame through the lifting cylinder. The lifting cylinder drives the cutting knife to move up and down or left and right relative to the jig. When the cutting knife is inserted into the jig, the product in the jig is cut off. During operation, only single-angle cutting can be achieved. When it is necessary to change the cutting angle of the hose, it is necessary to stop the machine, remove the cutting knife through the workpiece, and then adjust the cutting knife to the actual required cutting angle and fix it. Moreover, products with different cutting angles at both ends, such as straws, cannot be cut. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art solutions, the utility model provides a multi-angle rotary cutting mechanism for flexible pipes, which can effectively solve the technical problem of being unable to change the cutting angle during operation.
