Abstract

An undeformed gripper shuttle thread nipper assembly relates to a gripper shuttle thread nipper assembly structural technology of a weaving gripper loom, which comprises a head, a shoulder, and two arms connected below the shoulder; wherein the free ends of the two arms are respectively provided with a jaw clamp surface opposite with each other, the opposite distance between the bottom ends of the two arms are smaller than the distance between the two arms at the shoulder position. The undeformed gripper shuttle thread nipper assembly is arranged onto the barrel case after deformation. The two arms are not easy to be broken during weaving, the clamping force of the nipper jaws is not easy to be reduced, the life time is prolonged and the machine down time is decreased, the stability of the filling insertion is improved.

Description

Projectile shuttle yarn folder before the distortion

Technical field

The utility model relates to a textile machine equipment, the projectile shuttle yarn clamping structure technology of gripper shuttle loom.

Background technology

Projectile shuttle yarn folder is a vitals of gripper shuttle loom, and it is connected when weaving in the projectile shuttle, and the weft yarn that will be positioned at loom one side by its jaw brings to opposite side.The half-cooked production. art of existing yarn is: make a rounded nose earlier, in head, be provided with the installing hole that is connected with bobbin case, its shoulder is following to be formed and two wide arms of shoulder, the distance that has 4mm left and right sides broad between the end of two arms, the end of two arms is shaped on relative clamping surface, i.e. jaw respectively; And then apply mechanical pressure to two arms of yarn folder, and making two arm tools distortion and have prestressing force, the jaw distance diminishes.The yarn folder that forms so just can be installed in and carry out work in the bobbin case.This projectile shuttle yarn folder easily produces fracture after going up machine at two arm places, and its chucking power diminishes easily in process of production, makes the projectile shuttle ability of losing the job, and causes shutdown.

The utility model content

The utility model purpose is to design the not projectile shuttle yarn folder before the distortion that is difficult for reducing of easy fracture, chucking power of a kind of arm.

The utility model comprises head, shoulder, is connected two arms under the shoulder, and the free end of two arms is respectively equipped with relative clamping surface, and the lower end relative distance of two arms is little in the distance of shoulder than two arms.

This undeformed projectile shuttle yarn folder is installed on the bobbin case again through after the distortion, and two arms are difficult for rupturing when weaving, and the chucking power of jaw is difficult for diminishing, and prolonged its service life, reduces outage rate, improves the stability of wefting insertion.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Among the figure, 1 head, 2,3 installing holes, 4 shoulders, 5 left arms, 6 right arms, 7 jaws.

The specific embodiment

As shown in the figure, head is circular, wherein offers an installing hole 2, and with the circular curve transition, shoulder 4 offers another installing hole 3 at the middle part between shoulder 4 and the head 1.

Left and right two

arms

5,6 are connected shoulder 4 times, and gradually little from the distance between shoulder 4 two arms, 5,6 outermost down, that is, the lower end relative distance of two

arms

5,6 is little in the distance of shoulder 4 than two arms 5,6.The free end of two

arms

5,6 is respectively equipped with relative clamping surface, and the free end phase mutual edge distance of two

arms

5,6 is 0～0.6mm.

Above clamping surface can be a different shape.

Claims

1, the folder of the projectile shuttle yarn before the distortion comprises head, shoulder, is connected two arms under the shoulder, and the free end of two arms is respectively equipped with relative clamping surface, it is characterized in that the lower end relative distance of two arms is little in the distance of shoulder than two arms.
