Description
Technical Field
The invention relates to a weft insertion device of a gripper shuttle loom, in particular to a loom capable of automatically pushing the weft insertion device, which is particularly suitable for the field of textiles.
Background
The existing shuttleless weft insertion looms are mainly divided into air jet looms, water jet looms, rapier looms and projectile looms. In which rapier looms and gripper looms use active weft insertion tools (grippers with grippers or rapier heads). Both looms accelerate and then decelerate to 0 during weft insertion before weft yarn cross-over. The kinetic energy of weft insertion in the process is greatly wasted, and even additional energy is consumed to reduce the weft insertion kinetic energy to 0. Especially for the weaving equipment with ultra-wide width, the weft insertion requires extremely large kinetic energy (for example, for the 12m width, the weft insertion kinetic energy is required to reach 126 m/s), and the process of carrying out weft yarn connection by the weaving machine requires that the gripper or the rapier is in a relative static state relative to the weft yarn connection device. The ultra-wide width 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 end coils of the loom is used for acceleration, and the other end of the two end coils of the loom is used for deceleration. If the kinetic energy of weft insertion can be recovered, the energy utilization rate of the ultra-wide breadth weaving equipment can be greatly improved.
