Embodiment 1

[0019] Embodiment one: see attached figure 1 , 2 As shown, a loom shuttle with a weft yarn tension controller includes a cavity housing 1 with a yarn guide port 6, a bobbin 5 for storing weft yarn, and a rotary spring 3 that can generate torsional moment, and is fixed in the housing laterally. The fixing wire 2. The shell 1 is made of nylon material, which has the characteristics of wear resistance, rolling resistance, impact resistance, good dimensional stability and high fatigue resistance; the surface is coated with excellent wear resistance, antistatic and heat dissipation performance , to meet the needs of the weaving process. The fixed steel wire 2 of the replaceable bobbin 5 is made of fine-grained hot-rolled high-quality steel HRBF500, with a yield strength of more than 500 MPa and an elongation of more than 15%. One end of the fixed steel wire is fixed to the shell, and the other end passes through the groove on the shell. to constrain the position of the steel wir...

Embodiment 2

[0022] Embodiment two: see image 3 As shown, a loom shuttle with a weft tension controller is similar in structure to Embodiment 1. As the use time of the shuttle increases, the coefficient of friction between the half cylinder and the rotating disc will change, and the effect of changing the friction force by adjusting the screw will be weakened. At this time, the screw must be adjusted in a large range. Adjustment, and then cause the rotating disc to deviate from the original position inside the shuttle, and problems occur. In order to effectively improve this defect, we can simultaneously increase a lower adjusting screw 15 having the same effect as the upper adjusting screw 9 at a symmetrical position about the center line of the shuttle. When the shuttle is in use, a good effect can be achieved by adjusting this group of mutually symmetrical screws, which mainly includes two aspects. One: The simultaneous action of a group of symmetrical adjustment screws can adjust th...

Embodiment 3

[0023]Embodiment 3: A complete set of components as described in Embodiments 1 and 2 jointly constitute a loom shuttle device with a weft yarn tension control function. This device can change the friction between the semi-cylindrical body and the rotating disc according to different needs. The force realizes the function of controlling the tension of the weft yarn well. Although the device works well, it is relatively complicated. Sometimes the weft yarn does not have high requirements on the tension control effect, it only needs to be kept in a non-relaxed state. Based on this, it is particularly necessary to design a loom shuttle that is simple and easy to process and can keep the weft yarn in a non-relaxed state. This shuttle device omits the weft tension control devices 3, 4, 7, 8, 9, 10, 11, 12, 13 and 14 described in the first and second embodiments, and there are two Grooves, each fixing a weft tension control spring in it, one end of the spring is fixed inside the shu...

Abstract

The invention discloses a loom shuttle with weft yarn tension controllers. The loom shuttle comprises a shell, the two weft yarn tension controllers and rotary springs. A cavity is arranged in the middle of the shell, a yarn guide opening is formed in the shell, a spool for storing weft yarns is arranged in the shell and sleeves an axial fixing steel wire in the shell, and the two symmetrical weft yarn tension controllers are arranged on two sides of the spool and comprise rotary discs, lower sleeves and upper sleeves; lower half cylinders and lower springs are arranged in the lower sleeves, the lower half cylinders upper half cylinders are in contact with the rotary discs, upper half cylinders, upper springs and upper adjusting screws are arranged in the upper sleeves, the upper half cylinders are in contact with the rotary discs, and the upper adjusting screws are in contact with the upper springs; the rotary springs are connected with the rotary discs and the spool. The loom shuttle has the advantages that the problem of fringe of fabrics due to loose weft yarns in weaving procedures of looms can be effectively solved by the aid of the loom shuttle, and accordingly the quality level of woven products can be upgraded; tension of weft yarns can be uniformly controlled, accordingly, weft yarn breakage phenomena can be prevented, and the weaving efficiency can be improved; the weaving speeds can be increased, and the production cost can be reduced; the loom shuttle is simple in structure and low in repair and maintenance cost.

Description

technical field [0001] The invention relates to a textile machinery equipment, in particular to a weft yarn tension controller arranged in a loom shuttle. Background technique [0002] The loom shuttle is a device used for weft insertion during the weaving process. The yarn passes through the warp shed under the guidance of the shuttle, and cooperates with the beating parts on the loom to complete the weaving process of the fabric. Therefore, the shuttle is an essential and important component in the weaving process. Most of the shuttles are made of materials such as persimmon wood, oak oak, laminated wood or nylon. The size and shape depend on random types and needs. They have the characteristics of small friction coefficient, toughness and wear resistance. When the shuttle pulls the yarn for weaving, due to the inertia of the weft insertion action of the shuttle, the weft yarn will be excessively unwound on the bobbin where the weft yarn is stored, so that the weft yarn ...
