Intersia pattern shuttle box for flat-bed knitting machine

Abstract

This invention relates to an applique shuttle box on a horizontal braider including a box, an outside cover plate, an inside cover plate, an anti-bumping device, a locking device and a yarn nozzle moving device, in which, the anti-bumping device and the locking device are set at the top and middle of the box, the nozzle moving device is set at the top of the outside of the box and right and left center, the outside and internal cover plates are connected with the outside and inside of the box, in which, the locking device is composed of two clamp pins, two release springs, two locking levers, a drive lever and a pair of incomplete gears, said nozzle device is composed of a drive plate, a leaf spring, a nozzle fixing plate, a spacing swing block and a spacing unit. Advantage: 1, the small transverse diameter of the shuttle box reduces idle running and increases weaving efficiency, 2, the location of the box is accurate and stable since the locking and the guide way are not coplanary, 3, light actions of locking and loosing, 4, simple structure of the devices in the box.

Description

technical field [0001] The invention relates to a flat knitting machine, more particularly to an intarsia shuttle box on the flat knitting machine. Background technique [0002] When the flat knitting machine is performing intarsia knitting, several yarn feeders each hold a color of knitting thread and move with the intarsia box, and feed the knitting needles on the corresponding positions of the needle bed according to the relevant programs stored in the computer of the flat knitting machine. thread to weave a woven intarsia pattern consisting of several colors. [0003] The yarn feeder is connected to the yarn feeder fixing plate of the intarsia shuttle box, and the intarsia shuttle box moves or locks on the upper position on the shuttle bar according to the weaving needs, and the movement or locking of the intarsia shuttle box is performed by the controlled by the locking mechanism. Whether the yarn feeder feeds the thread to the knitting needle at the corresponding pos...

AI Technical Summary

Problems solved by technology

[0004] In the existing intarsia shuttle box, the locking surface and the guide surface in the locking mechanism are on the same plane. After using for a period of time, the guide surface will wear and tear, and this wear will affect the lock function of this surface that also acts as a lock. tight reliability

The intarsia shuttle box cannot be accurately locked on a certain position of the shuttle bar, and the positioning accuracy of the yarn feeder is affected, thereby affecting the weaving pattern

According to the weaving requirements, the positioning accuracy of the yarn feeder should not be greater than the spacing of 1 to 2 needles, and the existing intarsia shuttle box is generally difficult to achieve due to the wear of the guide surface after being used for a period of time.

In addition, the locking mechanism on the existing intarsia shuttle box is relatively complicated, and a large force is required from the locked state to the opening, and the locking and opening are not easy and dexterous

[0005] The yarn feeder moving device in the existing intarsia shuttle box is generally a pair of laterally symmetrical cam mechanisms, and the mechanism is relatively complicated, so that the lateral dimension of the intarsia shuttle box is relatively large, with a maximum size of 140 mm

The large transverse size of the shuttle box will increase the idle travel of the machine head, thereby reducing the weaving efficiency
