Problems solved by technology

However, the aforementioned method will virtually increase the cost of equipment, or increase the working time during weaving, which is not conducive to reducing costs or improving production efficiency.
[0007] At present, if you want to transport multiple weft yarns into the shed at one time, it is impossible to do it with the existing weft insertion mechanism. The sword head of the shed cannot exit smoothly and other defects

Embodiment 1

[0037] Embodiment one: if figure 1 , 2 , 3, and 4, the present embodiment includes a frame, and an opening mechanism installed on the frame, a weft insertion mechanism, a weft beating mechanism, a warp let-off mechanism and a coiling mechanism, and the weft insertion mechanism includes a weft feeding sword, which is installed on The weft feeding clip on the side of the weft sending sword, the weft sending and passing sword mechanism matched with the weft sending sword, the weft connecting sword matched with the weft sending sword, the weft receiving and passing sword mechanism matched with the weft connecting sword, the flexible Sword belt, sword wheel, guide device and sword opening mechanism. Wherein the frame is also equipped with a power source, the general power source is a motor, the output shaft of the motor is coaxially fixed with a main shaft 11, and a pendulum crank 12 is fixed on the main shaft 11; a pendulum 2 is hinged on the frame, Then latitude sword 3, flexib...

Embodiment 2

[0041] Embodiment 2: This embodiment is a method for operating a rapier loom, comprising the following steps:

[0042] Step 1, the warp is separated up and down by a shedding mechanism to form a shed;

[0043] Step 2, several weft yarns form a weft yarn bundle, which is fixed by the weft supply clamping member, and the weft feeding sword picks up the weft yarn bundle with the help of the weft feeding and passing sword mechanism, and carries the weft yarn bundle from one side of the shed to the other. side push;

[0044] Step 3, the weft receiving sword 3 moves toward the close weft sending sword 8 with the help of the weft receiving and passing sword mechanism 7, and completes the handover of the weft yarn bundle with the weft sending sword 8 at a position close to the other side of the shed. Beam exits from weft sending sword 8;

[0045] Step 4, when the weft-connecting sword 3 exits the shed with the weft bundle, the beating mechanism pushes the weft bundle introduced into...

Abstract

The invention discloses a rapier loom for weft roving weaving and an operation method thereof. The rapier loom comprises a frame, a shedding mechanism, a weft insertion mechanism, a beating-up mechanism, a warp feeding mechanism and a winding mechanism and is characterized in that a taker comprises a gripper seat, a taker gripper, a reset spring and a limit part, the gripper seat is in linkage with a taker rapier transmission mechanism through a flexible rapier belt, the taker gripper is arranged on the gripper seat, the taker gripper is coordinated with the gripper seat in a hinged manner, the reset spring is used for driving a hook tip part on the taker gripper to swing upwards, and the limit part is used for limiting the upward swinging angle of the hook tip part on the taker gripper. The rapier loom has the advantages that at least two wefts can be fed into a shed in one step, smooth hand over between a giver gripper and the taker gripper can be guaranteed after the wefts are fed,fabric with multiple wefts in the weft direction can be formed through the beating-up mechanism, the fabric can mix wefts of different colors into weft roving so as to increase weftwise attractiveness, and weftwise fabric strength can be increased at the same time.

Description

technical field [0001] The invention relates to a textile machine, in particular to a rapier loom for weft yarn bundle weaving. [0002] The invention relates to an operating method of a textile machine, in particular to an operating method of a rapier loom for weft yarn bundle weaving. Background technique [0003] The rapier loom is the mainstream machine in the loom. It has the advantages of high speed, stability, and good variety adaptability. It is the first choice for weaving various grades of clothing fabrics and other gray fabrics. Among shuttleless looms, the weft insertion principle of rapier looms was first proposed. At first it was a single rapier, and later a rapier loom with two rapier weft insertion was invented. The first International Textile Machinery Exhibition (ITMA) in 1951 exhibited the prototype of the rapier loom, and the shuttleless loom was rated as a new technology at this exhibition. [0004] Donghua University Press published "Modern Weaving Te...
