Hingeless rocking bar slide block mechanism and wefting rapier head for rapier loom

Abstract

The invention discloses a hingeless rocking bar slide block mechanism, which comprises a rocking bar, a slide bock and a return spring, wherein the slide block is glidingly arranged on a plane A, the return spring drives the slide block to return, and the slide block is used for driving a load. The hingeless rocking bar slide block mechanism is characterized in that the rocking bar is an elastic component, and comprises a driving part, an elastic deformation part and a positioning part, the positioning part is fixed with a plane B, and the positioning part is connected with the driving part through the elastic deformation part; the driving part comprises an input part and an output part, the output part is abutted against one surface of the slide block, the two butted surfaces are anastomotic with each other, and when the input part is stressed and is downwards pressed, the elastic deformation part is stressed to deform, so that the output part generates displacement, and the slide block is pushed to move; the plane A and the plane B are respectively planes on a machine body; the rigidity of the driving part is greater than that of the elastic deformation part. The hingeless rocking bar slide block mechanism has the advantages that after the structure is adopted, a transmission structure is simplified, so that a rapier head manufactured by the slide block mechanism is smaller and lighter.

Description

technical field [0001] The invention relates to a hingeless rocker slider mechanism and a weft-connecting rapier for a rapier loom. Background technique [0002] In the field of light industrial machinery such as textile machinery, packaging machinery and switching appliances, in order to change the direction of force, the direction of movement and the way of movement, crank slider mechanisms, swing guide rod mechanisms, etc. are commonly used. These mechanisms are composed of rods and structural hinges. , so there are many parts, the structure volume is large, it will occupy a large space, and the disadvantages are high cost. [0003] For example, the publication number is CN2011655578, and the utility model patent titled "weft rapier of loom" discloses a weft rapier of loom, which includes a housing and a release mechanism. The release mechanism includes a Outer coat, an angular connecting rod fixedly connected with one end of the outer coat, an inner sleeve arranged at t...

Problems solved by technology

However, the number of unwinding and clamping actions of this kind of sword head reaches 180-450 times / min. During such high-frequency operation, the hinges and screws between the angle-shaped connecting rod and the outer cover and between the inner cover and the connecting plate are fixed. There will be damage, such as the hinge shaft flying out, causing the sword head to be damaged and unable to work and break the cloth; at the same time, the sword head of this structure cannot be miniaturized, so that the shed of the loom cannot be reduced, thus making the speed of the loom It cannot be lifted; and the large shed makes the warp yarn tension change too much, which is easy to cause damage to the warp yarn
