Description

Technical Field

[0001] This utility model relates to the design of wire cutting equipment, and more particularly to a wire tensioning mechanism with a linear guiding structure. Background Technology

[0002] Patent document CN219131034U discloses a wire tensioning device, which includes a cutting machine body. A base plate is fixedly mounted on the lower end of the cutting machine body, and a motor is fixedly mounted on the surface of the base plate. One end of a cutting wire is fixedly mounted on the outer wall of a wire roller, and the cutting wire is wound around the outer wall of the wire roller and adheres to the outer wall of a limiting wheel. The other end of the cutting wire passes through a stabilizing structure and is connected to the upper arm of the cutting machine. An elastic top wire structure is fixedly mounted on the side wall of the cutting machine body. The elastic top wire structure is in close contact with the cutting wire. Through the action of the elastic top wire structure, when a certain amount of cutting wire is released from the wire roller, the cutting wire can be kept taut at all times, ensuring the tension effect of the cutting wire and ensuring the normal operation of the equipment. However, the elastic top wire structure in this wire tensioning device mainly relies on the elastic force of the spring for automatic adjustment, which makes it difficult to achieve precise tension control and results in poor operational stability, affecting the cutting accuracy of the cutting wire. Therefore, it is necessary to optimize the structure of this wire tensioning mechanism to overcome the above-mentioned defects. Utility Model Content
