Description

Multi-arm opening device of water jet loom

Technical Field

The utility model relates to a technical field of loom especially relates to a water jet loom multi-arm shedding device.

Background

The water jet loom has the characteristics of simple weft insertion system and high strength of warp raw materials, so the water jet loom has high rotating speed and high requirements on a main transmission motor, namely high starting torque and reverse torque of quick braking, and frequent starting impact current caused by frequent forward and reverse inching needs to be considered. Because of the unique working environment (the working environment has high humidity), the motor is provided with high insulating property and sealing property. The motor of the water jet loom has to have higher starting torque to meet the initial beating-up force of the loom and avoid weaving weft defects, and in order to meet the rapid braking of the loom, the rotor of the motor has to bear higher torque, and a control system of the water jet loom is an important component. The control system of the water-jet loom has the same functions as other shuttleless looms, and is mainly used for ensuring the normal work of the loom and completing the tasks of quick start, positioning brake, fault detection, electronic weft storage, electronic warp let-off, electronic winding and the like of the water-jet loom. The control system takes a CPU as a control center, and controls the preparation, operation, forward rotation, reverse rotation, stop, positioning brake and various fault checks (mainly comprising warp yarn over-tension, left and right twisting edges, front and back waste silk, fixed length, weft yarn detection and the like) of the loom through an executive element after analysis processing, and the single-chip electromagnetic brake is generally adopted by the water jet loom. The friction type friction plate consists of a moving plate (made of metal friction materials) and a fixed plate (made of nonmetal friction materials and embedded with coils). It has simple structure and convenient use. The electromagnetic brake is divided into a single coil and a double coil according to the coil types. In order to ensure sufficient starting and operating torque for a water jet loom, the main motor belt must have sufficient tension. The belt tension detection is usually carried out by using a direct-pressure type tension meter, and the water-jet loom mainly takes nylon yarn weaving and polyester flat spinning in the 80 s, and along with the rapid development of the synthetic fiber silk-like fabric processing technology, the variety limitation has been greatly broken through. With the increase of market demand, the application of the water jet loom is more and more extensive.

However, when the next water jet loom actually sprays water to penetrate through the warps and the wefts, the problems that the warps and the wefts are not overlapped and inserted uniformly, and part of the warps and the wefts are crossed exist, so that the water jet loom is uneven in product production and not beneficial to the actual use of the water jet loom.
