Embodiment
[0023] Renovate the applicant's existing spinning machine equipment, specifically install a 370WA variable frequency motor at the rear of the spinning machine, install 35 movable pulleys with a diameter of ￠50 on both sides of the body and the front and rear of the spinning machine, and use a 37.6-meter-long , the rough rubber garden belt with a diameter of ￠10mm runs counterclockwise at a constant speed, the belt runs under the yarn, and the yarn is in close contact with the belt. With a certain twist, it overcomes the problems of small twist, low strength, and easy end breakage in the triangular area, so that low-torque yarn can be spun smoothly. The specific effect is as follows:
[0024] 1. After installing the twist assisting device, the broken end of the spun yarn is significantly reduced when the yarn is 1,000 spindles.
[0025] Before and after the installation of the twist assist device, the comparison of end breaks at 1,000 spindles:
[0026]
[0027] 2. After i...

Abstract
The invention relates to a spinning machine, specifically to a low-torque yarn device. The low-torque yarn device comprises a headstock and a tailstock of the spinning machine and two rows of rockingframes arranged on the two sides between the headstock and the tailstock, wherein a twisting winding mechanism is correspondingly arranged on the lower side of each rocking frame; a spindle is arranged on the twisting winding mechanism; yarn conveyed downwards by each rocking frame is twisted and wound on the spindle through the twisting winding mechanism; and a twisting triangular area formed ina twisting process is provided with a twisting auxiliary mechanism capable of reducing yarn torque and twist coefficient. The low-torque yarn device is modified on an existing spinning machine throughequipment, and the yarn twisting auxiliary mechanism is additionally arranged in the twisting triangular area in order to drive the yarn to rotate in the twisting process, so that the problems of lowstrength and difficulty in spinning of the low twist yarn are solved, the yarn with the low twist coefficient and low torque is obtained, the market needs are met, and the market blank is filled.
Description
technical field [0001] The present invention relates to a spinning machine, in particular to a low torque yarn device. Background technique [0002] For yarn, when its strength reaches the critical point, the greater the twist, the better the strength, and it will gradually decrease after exceeding the critical point. The yarn spun by traditional spinning technology has a relatively large twist coefficient, generally between 360 and 400, and the cloth surface woven in this way is relatively hard. However, products with a twist coefficient of 290-310 have low yarn strength, and when spun on existing equipment, there are many yarn breakages, low production efficiency, and poor quality, which cannot meet customer requirements. Contents of the invention [0003] In view of the above technical problems, the present invention provides a low-torque yarn device for producing yarns with better quality and lower twist coefficient. [0004] The technical solution adopted by the pre...
