Description

Technical Field

[0001] The utility model belongs to the technical field of beating-up dynamic balancing, and in particular relates to a beating-up dynamic balancing device for a loom. Background Art

[0002] A loom is a machine used to interweave two or more groups of yarns at right angles to form fabrics. There are many types of looms. For example, according to the weft insertion method, they can be divided into two categories: shuttle looms and shuttleless looms. There are various ways of weft insertion for shuttleless looms, including rapier, air jet, water jet, projectile, multi-shed and weaving. Air jet uses a jet of compressed air to pull the weft yarn and bring it through the shed. Water jet uses water as the weft insertion medium to generate frictional traction on the weft yarn by jetting water, so that the weft yarn on the fixed bobbin is introduced into the shed.

[0003] The reed claw is an important component of the loom and directly affects the quality of the weaving. Looms with a width of more than 10 meters have higher requirements for the reed claw. The reed claw is prone to vibration during high-speed movement, and the magnitude of the vibration directly affects the density of the weft. In order to ensure the working state of the reed claw, multiple transmission swing arm components need to be installed to ensure the stability of the reed claw. However, the crankshaft is also increased accordingly. The existing equipment is relatively fixed. Simply adding a crankshaft increases the cost of improving the equipment, and it is difficult to add a crankshaft according to actual conditions, which increases the difficulty of improvement.
