Description
Technical Field
The invention relates to a weft insertion device of a projectile loom, in particular to a loom with an automatic weft insertion device, which is particularly suitable for the textile field.
Background
The existing shuttleless weft insertion loom is mainly divided into an air jet loom, a water jet loom, a rapier loom and a projectile loom. Wherein gripper looms and gripper looms use positive weft insertion tools (grippers or gripper heads with grippers). Both looms accelerate first and then decelerate to 0 and then make a weft yarn handoff at the time of weft insertion. The kinetic energy of the weft insertion in this process is extremely wasted and even additional energy is consumed to reduce the kinetic energy of the weft insertion to 0. Particularly for ultra wide width weaving equipment, the weft insertion requires a great kinetic energy (e.g. for a 12m width, the weft insertion kinetic energy is up to 126 m/s), whereas the weft yarn passing process of the weaving machine requires the gripper or rapier to be in a relatively stationary state with respect to the weft yarn passing device. The ultra-wide-amplitude electromagnetic weft insertion system is still in a research stage at present, and the existing scheme at present comprises the following steps: one end of the two ends of the loom is used for acceleration, and the other end is used for deceleration. If the kinetic energy of weft insertion can be recovered, the energy utilization rate of the ultra-wide-width textile equipment can be greatly improved.
Chinese patent CN200880006221.2, the invention patent with publication date 3/10 2010 discloses a gripper weaving machine provided with a bringer gripper and a deflecting guide on which a weft thread can be rested before being fed into a weaving shed 9 by means of the bringer gripper 2, wherein the deflecting guide comprises a groove and the bringer gripper comprises a thread clamp and wherein the thread clamp interacts with a thread guiding element for the thread clamp, which moves through the groove during the pick-up of a weft thread in order to pick up a weft thread rested on the deflecting guide. The invention also discloses a bringer gripper and a deflecting guide for use in a gripper loom, which minimizes the risk of breaking a weft yarn during its pick-up, but which nevertheless has the following drawbacks: weft insertion efficiency is low and operation is not intelligent enough.
