A Rapier Loom with Improved Structure

Abstract

The invention provides a rapier loom with an improved structure. The rapier loom comprises a worktable, a warp feeding mechanism, a weft feeding mechanism, a waste edge cutting mechanism and a winding mechanism, wherein a first warp shaft and a second warp shaft are arranged in front of the warp feeding mechanism; a first warp leading shaft group is arranged between the first warp shaft and the warp feeding mechanism, and a second warp leading shaft group is arranged between the second warp shaft and the warp feeding mechanism; each of the first warp leading shaft group and the second warp leading shaft group comprises a warp leading shaft I, a warp leading shaft II and a warp leading shaft III which are adjacently arrayed in a triangular shape; gaps through which weft yarns penetrate are formed each two of each warp leading shaft I, each warp leading shaft II and each warp leading shaft III; the winding mechanism comprises a winding rack a driving motor, a traction shaft, a winding shaft and a pressing shaft capable of applying pressure to woven cloth in a winding process; the pressing shaft is arranged just above the winding shaft; an upward supporting frame is mounted on the winding rack; two elastic cantilevers, which are suspended longitudinally, are arranged on the supporting frame; the end parts of the elastic cantilevers are connected with a mounting rod which is parallel to the winding shaft; and the pressing shaft is mounted on the mounting rod.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and relates to a rapier loom with an improved structure. Background technique [0002] Rapier looms are currently the most widely used shuttleless looms. In addition to the characteristics of high speed, high degree of automation, and high-efficiency survival of shuttleless looms, the positive weft insertion method has strong variety adaptability and can adapt to The weft insertion of various yarns, and the rapier loom also has obvious advantages in multi-color weft weaving, and can produce yarn-dyed products with up to 16 color weft yarns. As the shuttleless loom replaces the shuttle loom, the weaving The efficiency of the loom has been greatly improved, and the shuttleless loom has become the development direction of the world's textile machine industry. [0003] In the rapier loom processing process, the edge of the woven cloth surface needs to be cut because it is very uneven. The c...

[0004] The movable cutter body of this structure rotates under the action of external force, thereby cooperates with the fixed cutter body to complete the shearing. After the external force disappears, the torsion force of the spring is used to reset the movable cutter body. It will generate multiple reciprocating vibrations, so that it cannot be reset stably and quickly; secondly, after long-term use, the spring will produce elastic fatigue and affect the shearing action, resulting in the failure of the shearing motion and affecting the cutting quality of the cloth surface. Operation

In addition, the cutting device with the above structure cannot adjust the shearing force and the shearing length, and has poor adaptability

[0005] During the winding process of the weaving, the rotation speed of the winding roller must match the weaving speed of the weaving cloth and the transmission speed of the weaving cloth, which requires relatively high requirements for the transmission system of the rapier loom. When the rotation speed of the roller is higher than the weaving and conveying of the woven fabric, the woven fabric will be tightened, affecting the weaving and conveying in the early stage, and when the rotating speed of the take-up roller is too slow, it will cause the cloth surface to be pushed, and the winding deviation will easily occur. Shifting and uneven winding will affect the surface quality of the weaving fabric and increase the follow-up process
