High-strength roller of ring spinning frame

Abstract

The invention relates to a high-strength roller of a ring spinning frame. The high-strength roller comprises a roller (1), wherein one end of the roller (1) is a guide rod, the other end of the roller (1) is a guide hole, the guide rod end is provided with an external thread, the guide hole end is provided with an internal thread, and the diameter of the guide rod is the same as that of the guide hole; when the working face diameter d1 is phi25mm, the diameter of the guide rod d is equal to the diameter of the guide hole D and is equal to phi16.8-20mm; when the working face diameter d1 is phi27mm, the diameter of the guide rod d is equal to the diameter of the guide hole D and is equal to phi19.5-22mm; and the roller (1) is one or more of a front roller, a rear roller and a middle roller. According to the invention, the roller movement is transmitted in a staged manner; when a power supply applies torsion, the roller generates torsion, and the angle of torsion is inversely proportional to the diameter of the roller, so that the angle of torsion can be reduced by increasing of the diameter of the roller. Therefore, the high-strength roller provided by the invention has high torsion resistance and flex resistance, and is favorable to improvement of the yarn quality.

Description

technical field [0001] The invention belongs to the field of ring spinning frames, and in particular relates to a high-strength roller of a ring spinning frame. Background technique [0002] In the drafting system of the ring spinning machine, the rollers are stable and evenly moving, which play an important role in the yarn quality. At present, most of the spinning machine long cars are driven by two ends. The power of the drafting transmission comes from the main motor, which is transmitted to the front roller through the main shaft, and the front roller is then transmitted to the middle and rear rollers respectively. The movement of the rollers is transmitted joint by joint. When the working face diameter d 1 =Φ25mm, the diameter of the guide rod d=the diameter of the guide hole D=Φ16.5mm; when the diameter of the working surface d 1 =Φ27mm, guide rod diameter d=guide hole diameter D=Φ19mm, so when the spinning frame starts, due to the elastic deformation of the rollers...
