Abstract

The invention discloses a yarn tension constant device which mainly comprises a roller, a mandrel, a magnetic sleeve, a magnetic-lag sleeve, a sleeve base, an adjusting disc, an annular locking cover and a yarn guiding hook. A cylinder support which coincides with the axis of a roller inner cavity is fixedly arranged on the roller inner cavity. The mandrel is arranged in the cylinder support. The magnetic sleeve or the magnetic-lag sleeve is fixedly arranged on the back side surface of the mandrel in a sleeved mode. The magnetic sleeve or the magnetic-lag sleeve is fixed in the sleeve base which is arranged in the cylinder support in a rotating mode and enables the magnetic sleeve and the magnetic-lag sleeve to form partial sleeve connecting. An air gap is reserved between the two surfaces of the sleeve-connecting part. The adjusting disc is connected to the back face of the sleeve base in an inserting mode. The annular locking cover is arranged at an edge opening of the cylinder support in a rotating mode and abuts against the adjusting disc. The yarn guiding hook is arranged at the front end of the mandrel. According to the yarn tension constant device, torsion on the yarn guiding hook is generated by the corresponding magnetic sleeve and the corresponding magnetic-lag sleeve, the torsion is constant and can be adjusted accurately, and the roller can carry out storing and paying off on yarn properly according to the magnitude of tension of the yarn. The yarn tension constant device can guarantee the fact that yarn tension on forming cheese yarn is complete the same.

Description

technical field [0001] The invention belongs to the field of spinning machinery, and in particular relates to a device for keeping yarn tension constant during bobbin spinning. Background technique [0002] During the bobbin spinning process, the precise control of the yarn tension and keeping the yarn tension constant is a key technology related to the quality of the bobbin yarn, and it is also a technical difficulty of the spinning machine, especially the high-speed spinning machine. [0003] The yarn output speed of the spinning machine is constant, the rotation speed of the paper tube is constant when the yarn roll is formed, but the path of the yarn winding on the paper tube and the linear speed when it is wound at different positions of the paper tube are different. Constant changes, resulting in constant changes in yarn tension, especially in the spinning of cone yarns. In order to obtain a well-formed package, the tension of the yarn must first be adjusted precisely...
