[0002] When the cloth winding machine of the traditional circular knitting machine is unloading various fabrics, non-woven fabrics, etc., it is necessary to manually cut the fabric by pushing the cloth cutting knife or holding scissors, which is undoubtedly time-consuming and labor-intensive. During the manual cutting process of pushing the cloth cutting knife or directly using scissors, the cutting speed is slow and the cutting position is prone to deviation, which reduces the neatness of the cut fabric. Therefore, it is necessary to improve the mechanical structure to improve efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model is implemented through the following technical solutions: a polyethylene chain guide cloth cutting knife structure, including a circular cloth rolling machine, a DC speed regulating motor, and a cloth cutting knife frame, wherein the cloth cutting knife frame is installed on the circular cloth rolling machine, and is characterized in that: the bottom of the cloth cutting knife frame is electrically connected to the DC speed regulating motor, the DC speed regulating motor is provided with an output shaft, the output shaft has a chain gear, the support frame is connected to the circular cloth rolling machine through a long axis movable rod, one end of the support frame is embedded with the cloth cutting knife frame, and the cloth cutting knife frame is installed on the circular cloth rolling machine. The cloth cutting knife is arranged on the circular cloth rolling machine and connected with the circular cloth rolling machine. The cloth cutting knife frame is provided with a guide rail. The chain is assembled on the guide rail and matched with the guide rail in a clearance. The chain is engaged with the chain gear of the DC speed regulating motor. The chain and the guide rail are made of polyethylene. The characteristics of polyethylene are utilized to reduce the resistance of the chain and the guide rail during operation and reduce noise. The DC speed regulating motor is used as the power. The motor size is smaller and the torque is larger. At the same time, the rotation speed is stable. The slide rail is used for guidance to stabilize the cutting route, so that the cloth cutting is smoother.

[0004] As a further optimization of the present technical solution, the cloth cutter is provided with a cutting blade, a cloth cutter slider, and a connecting blade between the cloth cutter and the chain. One end of the cloth cutter slider has a connecting seat. The cutting blade is arranged on the connecting seat of the cloth cutter slider. The cutting blade is driven by a high-speed motor. The high-speed motor is used to realize high-speed rotation of the cutting blade, thereby increasing the flatness and speed of the incision.

[0005] As a further optimization of the technical solution, the chain connecting piece is a stepped structure, one end of which is fixed to the connecting seat of the guide rail by bolts, and the other end is arranged between the guide rail and the chain. The chain connecting piece and the cloth cutting knife frame are slidingly connected, and the chain connecting piece and the cloth cutting knife frame fully cooperate to increase the stability of the connection between the cloth cutting knife slider and the chain and the guide rail, making its reciprocating motion smoother.

[0006] Beneficial Effects

[0007] Compared with the prior art, the structure of the polyethylene chain guide cloth cutting knife of the utility model has the following advantages:

[0008] 1. The chain and guide rail of the utility model form a slide rail guide, which drives the cutting blade to slide. The cutting path will maintain linear motion to prevent deviation when the cloth is cut. The chain and guide rail are made of polyethylene. The characteristics of polyethylene are used to reduce the resistance of the chain and guide rail during operation and reduce noise. The DC speed regulating motor is used as the power of the slide rail guide. The motor is smaller in size, has greater torque, and rotates steadily and quickly, which further improves the smoothness and speed of the slide rail guide operation, makes the cutting path more stable and fast, and greatly improves the neatness and speed of cloth cutting.

[0009] 2. The cutting blade of the utility model is driven by a high-speed motor, which realizes high-speed rotation of the cutting blade. The force generated by the high-speed rotation of the cutting blade is used for rapid cutting, which further improves the flatness of the cutting cut and the cutting speed. The cutting blade cooperates with the cloth cutter frame through the chain connecting piece, which further improves the stability of the cutting blade when it is driven by the slide rail.
