TW type copper mesh loom
TW type copper mesh loom is developed by Shijiazhuang Fabric Machinery Co., Ltd. based on the early imported copper mesh machine through various improvements. On the basis of the simple structure, stable operation and high reliability of the old loom, its transmission mode and control system have been improved to make the machine operation more sensitive and maintenance more convenient. In addition, the adoption of a dobby machine and a multi-heald frame device expands the weaving range of the machine. It not only weaves copper mesh, but also produces high-quality polyester mesh products. This machine is an ideal loom with high quality and low price in the papermaking net industry. The main transmission mechanism is composed of a main electric motor and a pneumatic clutch. It has the characteristics of smooth starting and rapid braking, and is both safe and reliable. Shedding mechanism adopts double dobby mechanism, which can hang 8 heald frames, and each heald frame has 4 heald hanging points. Changing the mesh pattern can be achieved through the pattern nail conversion of the flower tube. The pick-up crank mounted on the central axis of the weft insertion mechanism hits the pick-up nose on the shuttle board. The shuttle board swings up and down, driving the pick-up stick to strike the shuttle for weft insertion. The shuttle pick-up force can be adjusted by adjusting the pick-up nose. position to control. Beating-up mechanism: The circular rotation of the crankshaft drives the connecting rod, and the rocking shaft connects the reed base foot to drive the reed base to reciprocate, achieving beat-up. The beat-up force is large, the rotation is stable, and the reliability is high. The beating force is about 1000kg/m. Warp let-off mechanism: The connecting rod on the density plate drives the pawl and ratchet, and drives the let-off roller through a pair of reduction gears and a pair of herringbone gears to send out the warp yarns. The amount of let-off is achieved by adjusting the position of the connecting rod on the density plate. Coiling mechanism: Heavy hammer type semi-positive and semi-negative coiling. The amount of coiling is determined by the amount of warp let-off. According to the weight of the weight, the tension of the mesh surface can be controlled. Pneumatic part: Programmable manipulator and angle encoder automatically control pneumatic components. Pneumatic shuttle making achieves precise shuttle making by adjusting the air intake of the cylinder. The shuttle making area is 90° to 280°; the automatic thread clamping and pay-off mechanism has a thread clamping area of 280° to 350° and a thread pay-off area of 350° to 50°. ; Automatic thread take-up and crimping mechanism, thread take-up and crimping area 10°~20°, thread take-up and crimping reset area 60°~80°.
