Rapier loom

Abstract

The invention provides a rapier loom which comprises a workbench, a warp let-off mechanism, a weft let-off mechanism, a slitter edge cutting mechanism and a rolling mechanism. The slitter edge cutting mechanism comprises a cutter rest, a fixed cutter body and a movable cutter body, the fixed cutter body is provided with a first blade, the movable cutter body is provided with a second blade, the fixed cutter body is fixed to the cutter rest in a height-adjustable mode, the movable cutter body is hinged to the fixed cutter body, and the first blade and the second blade abut against each other to form a cutting opening; the slitter edge cutting mechanism further comprises a motor driving the movable cutter body to rotate, a transmission shaft and a rotating disc, and the transmission shaft is controlled by the motor and fixedly connected to the center of the rotating disc; the cutter rest is provided with a longitudinal sliding groove, a sliding block is arranged in the sliding groove, a first connecting rod used for driving the sliding block to rise and fall is arranged between the sliding block and the rotating disc, a second connecting rod used for pushing and pulling the movable cutter body is arranged between the sliding block and the movable cutter body, one side of the sliding block is fixedly connected with the second connecting rod, and the second connecting rod is hinged to the movable cutter body; the other side of the sliding block is hinged to the first connecting rod, and the first connecting rod is hinged to the eccentric position of the rotating disc.

Description

technical field [0001] The invention belongs to the technical field of textile machinery and relates to a rapier loom. 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 cutting device in the prior ...

Problems solved by technology

[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
