Rolling cutter for ultrasonic high-speed rotary blowing discharging

Abstract

The invention belongs to the technical field of spinning, and discloses a rolling cutter for ultrasonic high-speed rotary blowing discharging. The rolling cutter is provided with a rolling cutter body, a central deep and long hole is formed in the shaft end face of the right side of the rolling cutter body, a section of threads is formed in the shaft end face of the central deep and long hole, andthe threads are connected with the rolling cutter body and a high-speed rotary joint; bearings are installed at the left end and the right end of the rolling cutter body, a synchronous wheel is fixedto the tail end of the shaft part of the left side of the rolling cutter body, the synchronous wheel and the rolling cutter body are connected through a tensioning sleeve, and the synchronous wheel is connected with a motor in a toothed mode. A thread hole in the right side of the rolling cutter body is connected with the rotary joint, the central deep and long hole communicates with a normal hole and a tangential hole, thus the gas is vented to the circumferential surface of the cutter body, and the action of blowing out waste, auxiliary feeding, and heat dissipation for an ultrasonic tool head is achieved. A protective blade is in a sine wave S-shaped pattern, the angle and height of the protective blade are both consistent with a cutting blade, and thus the service life of a die can beprolonged; and the wavelength on the left side is longer than that on the right side, and the action of preventing the ultrasonic tool head from loosening can be achieved.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a roller cutter for ultrasonic high-speed rotary air blowing and discharging. Background technique [0002] The current hob cutter has always been a big problem in cutting round holes, especially some small holes, dovetails, bevels and other molds with waste materials, and waste materials often stick to the blade during the hob cutting process. It affects the secondary cutting effect. The existing method is: to install foam on the entire stick, which will easily lead to material blockage, affect the transportation of cutting materials, and the waste discharge effect is not obvious. [0003] Most of the technology used now is to only process the required texture on the surface. There is no protective edge or the protective edge is to process two wide cylindrical protective rings on both ends. Without protective edges, it is easy to cause direct damage to the blade, a...

AI Technical Summary

Problems solved by technology

[0006] (1) During the rolling cutting process, waste materials often stick to the blade and affect the secondary cutting effect;

[0007] (2) The life of the roller knife is not long, and the blade is easy to wear or wear unevenly;

[0009] (4) The tool head is easy to loosen;

[0011] The above problems lead to extremely complicated machine debugging, which is also a difficulty and pain point in t
