Description

Twist stopper

Technical Field

The invention relates to a twisting stopper, in particular to a twisting stopper for preventing silk yarns from being wound.

Background

In the textile industry, raw POY yarn is drawn using the speed difference between a first roller and a second roller. The silk strips are twisted when passing through the spindle, so that the silk is a twisting area between the twisting stop device and the spindle, the silk strips are twisted in the direction of the silk strips and are subjected to heat setting in a hot box, and then the silk strips are cooled through a cooling plate, so that the direction of the twisting is fixed. The twisting direction between the spindle and the two rollers is opposite to the upper direction to form an untwisting area. Thus, the yarn becomes a high elastic yarn having a certain strength, elongation and crimp rate. In order to ensure the crimping effect of the filaments, the twisting zone of the filaments is generally controlled in a hot box, thereby eliminating the internal stresses of the filaments and stabilizing the filaments against deformation. For a machine type with a roller having a longer distance from the inlet of a hot box, such as an M-type elasticizer, one roller plays a role in twisting stopping, but for a T-type elasticizer and the like, a twisting stopping device is required because the distance of a Luo Ladao hot box is longer. The function of the twist stopper is to prevent the twist of the filament from being transferred from the hot box to the outside.

Then traditional twist stopping device material is lighter, and the rotational speed is very fast, and the required traction force of silk thread is also less, and when the silk thread broken string back, twist stopping device continues to rotate because inertia, twines the silk thread in twist stopping device, need carry out manual cleaning, extravagant manpower, causes production efficiency to reduce, and need open the hot box during the clearance, causes the hot box temperature unstability, has reduced the quality of other silk threads in the hot box. In addition, a gap is reserved between a twisting ring and side walls on two sides of the traditional twisting device, and the silk threads are easily wound in the gap, need to be manually cleaned and are difficult to clean.
