Tension control device for high-speed chain-type embroidery machine

Abstract

The invention discloses a tension control device for a high-speed chain-type embroidery machine. The device comprises a base, a left support is fixedly connected on one side of the top end of the base, a controller is fixedly mounted on one side of the middle of the top end of the base, a wire drawing plate is fixedly mounted at the top end of the left support, first rotating shafts are fixedly mounted on two sides of the middle of the front end of the wire drawing plate, first wire drawing wheels are rotatably connected at the front ends of the outer sides of the first rotating shafts throughmagnetic bearings, a sliding groove is formed in the middle bottom of the front end of the wire drawing plate, a second rotating shaft is arranged in the sliding groove, a slider is embedded into theouter middle of the second rotating shaft, two sides of the slider are slidably connected with two inner sides of the sliding groove, a second wire drawing wheel is rotatably connected at the outer front end of the second rotating shaft, and an electric telescopic rod is arranged on one rear side of the second rotating shaft. The device is provided with the wire drawing plate, the first wire drawing wheels and the second wire drawing wheel, so that the device has the advantages of controllable wire drawing tension, ideal wire drawing effects and the like.

Description

technical field [0001] The invention relates to the technical field of tension control equipment for high-speed chain embroidery machines, in particular to a tension control device for high-speed chain embroidery machines. Background technique [0002] Magnetic bearings are a form of support that supports loads or suspends rotors by magnetic force. In recent years, this kind of bearings has developed rapidly, especially in high-speed, low friction, high (low) temperature and vacuum environments. Compared with other supporting forms, magnetic bearings have unique advantages and have great development prospects; compared with traditional bearings, magnetic bearings are more suitable for use on high-speed chain embroidery machines, used to reduce frictional resistance of high-speed chain embroidery machines, and make embroidery threads The transmission is more stable and efficient.

AI Technical Summary

Problems solved by technology

[0004] 1. The transmission mode of the tension control equipment of the traditional high-speed chain embroidery machine basically adopts the traditional mechanical transmission mode. Under the high-speed operation state, the wear and tear are large, the heat is large, and a stable tension state cannot be formed.

[0005] 2. The tension control equipment of the traditional high-speed chain embroidery machine has a complex structure, and usually uses a method to prevent the tension from being adjusted, and the degree of automation is relatively low.
