Technical field

The present invention relates to a kind of knotted net braiding equipments more particularly to a kind of overlength to move crossbeam bend preventing device, belongs to height Hold textile equipment technical field.

Background technique

In textile machine, there are many machine of breadth longer (6M), and some parts of knitting for knitting part cooperation for key install crossbeam Because of movement and spatial relationship, freely-supported only often is done in the two sides of overlength movement crossbeam, this results in the crossbeam of 6M long from recast With lower bent intermediate up to 60mm or so (laterally without constraint) or 10mm or so (laterally having constraint), deflection is too big, affects and knits Cooperation between part, so must there is corresponding measure to reduce beam deformation.

The lower hook quantity of knotted net braider is mounted on crossbeam up to 400 or more, so the length of crossbeam has been more than 6 Rice.According to the requirement of knotted net production technology, after rising to the bait to warp completion lopping campaign, lower hook can be along the lower hook rail of two sides Road moves up, and passes through through coil, catches on warp and return again to, and completes yarn hook movement.This time in movement, crossbeam does sky along trapped orbit Between move, only do freely-supported at both ends, centre is in vacant state, also does static support to crossbeam without any space, certainly will lead Tenesmus among crossbeam is caused, all lower hooks are not on a horizontal plane.Curved crossbeam will affect rise to the bait, lower hook and comb hook are matched It closes, causing to knot fails.

Summary of the invention

The technical problem to be solved by the present invention is solving the problems, such as overlength movement crossbeam how to be made to reduce deformation.

In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of overlength to move the anti-bending dress of crossbeam It sets, which is characterized in that crossbeam is moved including overlength, the both ends that overlength moves crossbeam pass through bearing support on lower hook track, under The outside of hook track, which is equipped with, drives lower hook movable connecting rod to transport overlength movement crossbeam along the lower hook that lower hook track moves reciprocatingly Dynamic motor, overlength move crossbeam front end and are equipped with lower hook pressing plate, and lower hook pressing plate is equipped with lower hook, is fixed with slot on overlength movement crossbeam Steel, channel steel are connect by least a set of link mechanism with the bending resistance shaft that can be rotated in fixed frame, and bending resistance shaft passes through at least 2 A fixed frame is connect with square steel, and square steel is fixed on rack.

Preferably, link mechanism described in every suit is by oscillating bearing, oscillating bearing pitman and bending resistance shaft swing arm Composition, one end of bending resistance shaft swing arm is fixedly connected with bending resistance shaft, the other end of bending resistance shaft swing arm by oscillating bearing and The other end of one end of oscillating bearing pitman, bearings pitman is connect with channel steel.

Preferably, the bending resistance shaft uses the seamless steel pipe of major diameter, high torsion stiffness.

Preferably, it is connected between one end and channel steel of the link mechanism by revolute pair.

The device of the invention is by installing connecting rods mechanism, by the shaft of overlength movement crossbeam and major diameter, high torsion stiffness Connection, thus achieve the purpose that reduce crossbeam bent intermediate, meanwhile, the dynamic support characteristic of link mechanism will not influence crossbeam Do spatial movement.Device through the invention eliminates overlength movement crossbeam by both ends freely-supported, and centre generates Bending Deformation Problem.

Mechanism composition of the invention is simple, convenient disassembly, and maintenance cost is low and high reliablity；The high torsion of bending resistance shaft is rigid Degree can greatly reduce the bent intermediate degree of overlength movement crossbeam, guarantee the quality of fabric；Overlength moves crossbeam and locally generates When bending, defect can be eliminated with pitman length by adjusting the bearing of link mechanism；The dynamic support characteristic of bend preventing device The spatial movement that will not influence overlength movement crossbeam, ensure that the timing of technique.
