Double-roller-type yarn twisting device

Abstract

The invention provides a double-roller-type yarn twisting device, and belongs to the technical field of textile machines. The device comprises a left twisting assembly, a right twisting assembly and atwisting driving assembly; a left twisting main shaft of the left twisting assembly is rotatably arranged on a left twisting supporting base, one end of a left connecting rod is hinged to a first left connecting rod supporting base, and the other end of the left connecting rod is hinged to a second left connecting rod supporting base; a left twisting roller is coaxially and fixedly connected to the right side of a left rotation bearing disc, a right twisting main shaft of the right twisting assembly is rotatably arranged on the left twisting supporting base and can slide axially, one end of aright connecting rod is hinged to a first right connecting rod supporting base, the other end of the right connecting rod is hinged to a second right connecting rod supporting base, and a right twisting roller is coaxially and fixedly connected to the left side of a right rotation bearing disc. By means of the device, two parallel twisting rollers with speed difference are utilized for rotating,and twisting of yarn is also achieved through axial and reciprocating movement between the two twisting rollers.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a double-roller yarn twisting device. Background technique [0002] Textile machinery is all kinds of mechanical equipment needed to process natural fibers or chemical fibers into textiles. Although the machinery for producing chemical fibers includes a variety of chemical machinery, it is now considered an extension of textile machinery and belongs to textile machinery in a broad sense. The processes required to process different fibers such as cotton, hemp, silk, wool, etc. into textiles are not the same, and some are completely different, so the machines required are also various and varied. Textile machinery is usually classified according to the production process, including: spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber spinning equipment, reeling equipment and non-woven fabric equipment. Twisting is an...

Problems solved by technology

The thread segment to be twisted first obtains a twist with each rotation of the spindle rod, and the twisted segment of thread is drawn out from the radial guide hole of the wire storage disk, and then passes through the fixed guide hook on the top, and the radial guide wire porcelain eye turns. A twist is added to the section of silk, but such twisting equipment not only has a complicated structure and high cost, but also has an unsatisfactory twisting effect.
