Description

Finished product drying and winding device for water jet loom

Technical Field

The invention belongs to the technical field of winding devices of water-jet looms, and particularly relates to a finished product drying and winding device for a water-jet loom.

Background

Water jet looms are shuttleless looms that use a jet of water to pull the weft through the shed. The friction traction force of the water-jet weft insertion to the weft yarn is larger than that of the air-jet weft insertion, the diffusivity is small, and the requirements of long-wire weft insertion such as synthetic fiber and glass fiber with smooth surfaces are met. Meanwhile, the conductivity of the composite fiber can be increased, and the static electricity in weaving can be effectively overcome. In addition, less energy is consumed by spraying the weft yarn, and the noise is lowest. A water-jet loom features that water is used as weft-inserting medium and the water jet is used to generate friction traction to weft yarn for leading the weft yarn on fixed bobbin to shed. Because the water flow is gathered well, the water jet loom has no water flow diffusion preventing device, even if the reed width of the water jet loom can reach more than two meters. The water jet loom has good water flow bundling property and large friction traction force of water to weft yarns, so that the flying speed of the weft yarns and the speed of the loom of the water jet loom are at the top of various looms. Is suitable for weaving hydrophobic fiber yarns such as synthetic fibers, glass fibers and the like, so the variety is limited. The general apparatus comprises: jet pump, water drop sealing dredging and recovering device, fabric dewatering and drying device, etc.

The weaving principle of the water jet loom is different from that of a shuttle loom and an air jet loom, the weft insertion process is finished by a weft insertion water pump through a weft insertion water column, the woven grey cloth is a wet blank but not a dry blank, if the grey cloth is directly rolled into a cloth roll, the grey cloth is easy to mildew, the quality abnormality such as tear and the like is easily caused, therefore, the grey cloth needs to be dried and dried before the cloth is rolled, the existing water jet loom is used for drying and drying the wet cloth only on the upper surface, the drying effect of the lower surface of the wet cloth is poor, the drying of the cloth is uneven up and down, the drying quality is poor, the working efficiency is low, the existing cloth rolling device is inconvenient to disassemble, the cloth rolling device is only connected with the water jet loom through cloth transmission, the cloth can be loosened in the transmission process, the cloth is not tight in the cloth rolling, wrinkles are easy to generate, and the quality problem is brought, therefore, a device having a tensioning mechanism solves the problems of the prior art.
