Problems solved by technology

As the preparation mechanism of the splicer, the untwisting device has a certain untwisting effect, but for the leg-twisting objects of chemical fibers and strands with high splicing strength and extremely difficult untwisting, the untwisting effect is not good. Ideal, so its adaptability and untwisting effect are very limited

Embodiment Construction

[0020] Such as figure 2 , image 3 As shown, the untwisting device of the present invention is an elongated tube and a through-hole structure with openings at both ends. The inside is a small hollow pipe, and its inlet end receives the end of the yarn to be processed. There are oblique holes 2 on the wall of the untwisting device, such as image 3 shown. At the same time, a strip-shaped tooth-like structure 4 is arranged on the inner top wall of the untwisting device, and the strip-shaped tooth-like structure is arranged along the longitudinal direction of the small pipe.

[0021] Figure 4 The thickness of the base of the elongated toothed structure shown should be consistent with the thickness of the tube wall of the untwister. If the thickness of the base is too high, the protruding entity of the base will hinder or weaken the rotating vortex of the airflow in the small pipe, thereby weakening the untwisting effect.

[0022] Figure 5 The angle between the shown incl...

Abstract

An untwisting device for an air twister is applied to a knotless air splicer for yarn spinning. The untwisting device is characterized by comprising an elongated pipe in a through hole structure with two ends open, a small duct hollow is arranged inside, the inlet end of the elongated pipe is used for receiving ends of yarns to be handled, the wall of the untwisting device is provided with an oblique hole close to the inlet end, and the inner wall of the untwisting device is provided with an elongated tooth structure which is vertically arranged along the small duct. The untwisting device for being mounted on the air twister is applicable to various types of yarns, is widely applicable and is especially applicable to untwisting of chemical fibers and strands, which are high in degree of twist and difficult to untwist.

Description

technical field [0001] The invention relates to an untwisting device on an empty twisting device. Background technique [0002] Knot-free air-splicing devices for spinning yarn are known, generally called "splicers", which splice two yarn ends to be spliced ​​in a knot-free manner. Before splicing, there is usually a mechanism for preparing or pre-treating the ends of the two yarns to be spliced, usually called an "untwister". In order to obtain a good connection effect of the yarn ends, it is necessary to pre-treat the yarn ends to completely untwist within a certain length of the yarn and make the fibers parallel to each other. [0003] existing technologies such as figure 1 The cylindrical untwisting device shown has a small pipe in the middle, and the compressed fluid flow passes through the small pipe in the axial direction. The small pipe is used to prepare the yarn end and is opposite to the axial direction of the small pipe. At a certain distance from the inlet en...
