Spinning yarn conveying tensioning device capable of automatically adjusting spinning yarns to prevent slacking

Abstract

The invention relates to the technical field of knitwear, and discloses a spinning yarn conveying tensioning device capable of automatically adjusting spinning yarns to prevent slacking. The device comprises a pay-off machine, and the outer side of the pay-off machine is movably connected with a pay-off drum; when a bobbin sleeves the outer side of the pay-off drum, a clamping block is squeezed torotate, and the bobbin is fixed, so that the bobbin is prevented from being separated from the pay-off drum in a spinning yarn conveying process of the bobbin; the spinning yarns are tightly attachedto the outer side of a second rotary disc, the second rotary disc is moved upwards to squeeze a spring, and when the spinning yarns are slacked, the second rotary disc is moved downwards under the action of the outer spring, so that subsequent straightening of the spinning yarns is facilitated and the property of linkage among structures is improved; and a first connecting rod moves downwards toenable a support rod to drive a first rotary disc to move upwards, the first rotary disc pulls the second rotary disc to move upwards through the spinning yarns, the spinning yarns are tightly attached to the outer side of the second rotary disc, and the spinning yarns are straightened again, so that the situation that the yarns are wound on the device due to slacking is avoided, and the situationthat the textile quality is poor due to slacking of the spinning yarns also can be avoided.

Description

technical field [0001] The invention relates to the technical field of needled textiles, in particular to a tensioning device for thread transmission that automatically adjusts the thread to prevent slack. Background technique [0002] Knitted textiles are processed and woven products, which are mainly divided into clothing textiles, decorative textiles and industrial products. Common knitted textiles include knitted garments, towels, gloves, blankets, etc., which permeate people's daily life. [0003] During the production process of knitted textiles, the yarn needs to be straightened and tightened so that the machine and equipment can weave. The loose yarn is easy to get off the pulley, entangled with each other or the machine equipment, causing the machine to malfunction and loosen. When the spun thread is spun, redundant coils will appear in the finished textile, which will affect the quality of the textile. Therefore, it is particularly important to keep the spun thread...

Problems solved by technology

[0003] During the production process of knitted textiles, the yarn needs to be straightened and tightened so that the machine and equipment can weave. The loose yarn is easy to get off the pulley, entangled with each other or the machine equipment, causing the machine to malfunction and loosen. When the spun thread is spun, redundant coils will appear in the finished textile, which will affect the quality of the textile. Therefore, it is particularly important to keep the spun thread in a tight state during the weaving process. The existing tensioner is a kind of thread that makes the spun thread Tight maintenance equipment, but the commonly used tensioner cannot automatically tighten the spinning thread, and manual adjustment is required, which requires staff to watch on the sidelines, which is a waste of manpower, and when adjusting, in order to ensure the textile The quality needs to suspend the equipment, the operation is very inconvenient, and the work efficiency of the textile is greatly reduced

[0004] Aiming at the deficiencies of the prior art, the present invention provides a tensioning device for yarn transmission that automatically adjusts the yarn to prevent slack, which has the advantages of automatic stretching and straightening of the yarn and convenient operation, and solves the problems of inconvenient operation and manual adjustment , it can prevent the spinning of the bobbin from being separated from the pay-off cylinder during the spinning transmission, which will affect the progress of the spinning transmission, and automatically adjust the loose spinning yarn to straighten the spinning yarn again, avoiding the occurrence of loose spinning and equipment entanglement situation, it can also avoid the poor quality of textiles due to loose yarn, free your hands and make the operation more convenient
