Pressure-adjustable yarn gripper for air-jet loom based on intelligent manufacturing principle

Abstract

The invention relates to the technical field of textile equipment, and discloses a pressure-adjustable yarn gripper for an air-jet loom based on the intelligent manufacturing principle. The pressure-adjustable yarn gripper comprises a machine frame, a cam is movably connected into the machine frame, a movable protruding block is movably connected to the exterior of the cam, an electromagnet is fixedly connected into the cam, a permanent magnet block is movably connected to the exterior of the electromagnet, and an electric contact block is movably connected to the exterior of the permanent magnet block. Through cooperative use of a pressure rod, a limiting sliding block, a sliding rod, a lifting rod, an adjusting rod and a threaded rod, the effect of increasing the yarn clamping pressure in the yarn clamping process is achieved, so that the yarn gripper meets the requirement for fabrics with small warp and weft density or small warp and weft cross weaving friction force, the use rangeof the yarn gripper is effectively widened, and the use effect of the yarn gripper is effectively improved; and loosening of the finished fabrics due to insufficient weft tension caused by insufficient clamping force is effectively avoided, so that the quality of the woven finished fabrics is effectively guaranteed, the textile effect is effectively improved, untwisting or retracting of yarns is effectively prevented, and the production efficiency is guaranteed.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a pressure-adjustable yarn gripper for an air-jet loom based on the principle of intelligent manufacturing. Background technique [0002] The air-jet loom is a machine that uses jetted airflow to pull the weft yarn through the shed for weaving. Air is used as the weft insertion medium, and the jetted compressed airflow generates frictional traction on the weft yarn to pull the weft yarn through the shed. In order to achieve the purpose of weft insertion, and in the process of weft insertion, the yarn gripper needs to be used together to achieve the effect of providing tension and preventing untwisting or retraction. [0003] However, the clamping time of the existing yarn clamps is not suitable for adjustment, the stability of the clamped yarn is not high, and the clamping tightness is not suitable for adjustment. When weaving fabrics with low warp and weft density or l...

Problems solved by technology

[0003] However, the clamping time of the existing yarn clamps is not suitable for adjustment, the stability of the clamped yarn is not high, and the clamping tightness is not suitable for adjustment. When weaving fabrics with low warp and weft density or low warp and weft twist weaving friction, the tension of the upper and lower warp yarns will be affected. It will cause the side weft yarn to shrink in the weft direction, and the side tissue will become looser, which will affect the quality of the finished fabric, thereby causing the quality of the finished textile fabric to deteriorate
