Abstract
Description
Technical Field
[0001] The invention relates to the field of cutting devices, in particular to a Teflon tube cutting device. Background Art
[0002] Teflon is the common name for polytetrafluoroethylene, a high molecular polymer made by polymerizing tetrafluoroethylene as a monomer. It is white, waxy, translucent, and has excellent heat and cold resistance. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. It is a commonly used engineering plastic with excellent performance and is used in many fields. In the process of making Teflon tubes, the Teflon tubes are cut at equal distances according to demand.
[0003] Patent application number: CN201811507437.9 discloses a Teflon tube precision automatic cutting equipment, including a frame, a Teflon tube conveying device, a Teflon tube cutting device, a Teflon tube turntable, and a turntable frame. The frame is provided with a frame table; the Teflon tube conveying device and the Teflon tube cutting device are respectively installed on the frame table, and the Teflon tube turntable is rotatably installed on the turntable frame. The system places a Teflon tube turntable on a turntable frame, pulls the tube from the turntable, and inserts it into a conveyor wheel mechanism. The conveyor wheel drive mechanism then drives the conveyor wheel mechanism forward to convey a fixed length of Teflon tube into a clamping mechanism. The cutting drive mechanism then drives the cutting mechanism to cut the Teflon tube clamped in the clamping mechanism. The conveyor wheel drive mechanism then drives the conveyor wheel mechanism forward to convey a fixed length of Teflon tube into the clamping mechanism and eject the cut tube forward. The tube is fed by the conveyor wheel and then cut by a blade. The rotation of the conveyor wheel applies friction to the tube, continuously feeding it forward. When the tube reaches the predetermined length, the cutter completes the cutting action. However, this type of device feeds the tube by pressing the conveyor wheel against it. The contact surface between the conveyor wheel and the tube is small, making it easy for the Teflon tube to slip and deviate, making it difficult to guarantee cutting length and accuracy.
