Abstract

The invention relates to textile machinery, relates to a weaving machine and makes it possible to reduce the breakage of the main threads by creating optimal air parameters in the warp zone. Cold water passes through tubes 11 to moisten the threads 2 of the base of the device 3, which is 5 ° C lower than the dew point temperature of the ambient air. When the air parameters near the surface increase, 1 beyond the optimum values of the sensor 20 sends a command to the operation of the actuator 19, which through the means 18 moves the device 3 closer to 1, which reduces the relative humidity and temperature of the surrounding air. The decrease in relative humidity occurs due to cooling of the air, which reduces the formation of condensate on the tubes 11. When the air parameters near the surface decrease, air 1 moves from device 1 to air 1. Air temperature in gap A increases and to a greater extent contributes to the formation of condensate on pipes 11 and relative air humidity. 1 hp f-ly, 1 ill.

Description

fS

The invention relates to textile engineering and relates to a weaving machine with a device for moistening the warp threads.

The purpose of the invention is to reduce the breakage of the warp threads by creating optimal air parameters in the warp zone.

The drawing shows the kinematic scheme of the loom.

The weaving machine has a base 1 for the threads 2 of the warp and a device 3 for wetting the warp 2. The warp threads 2 pass the rock 4 and healings 5 to the edge 6 of the fabric 7. The fabric 7 passes through the chest 8, val 9 and is wound onto a roller 10 The device 3 for moistening the yarns 2 of the base is made in the form of several tubes 11, each of which is parallel with its ends and alternately connected with its ends with the formation of a surface located coaxially with the longitudinal axis of the warder with a gap A relative to the outer surface of the first. but ho By moving the water, the tube 12 is connected by means of a flexible wire 13 to the cold water supply pipe 14, the temperature of which is lower than the dew point temperature of the ambient air by L ° C, and the last pipe 15 by means of a flexible hose 16 to the outlet pipe 17. The weaving machine has means 18; y1 automatic movement of the device 3 for wetting the base, including the actuator 19 and the sensor 20 for monitoring air parameters in the zone 1, located in the gap A between the tubes 11 of the device 3 for moistening the warp threads 2 and the base 1. Flexible hose and 13 and 16 have compensation loops 21 for allowing the device 3 to move towards 1 and vice versa as it moves towards 1 and when the ambient air parameters deviate from optimal values.

The loom works as follows

in the way

During the operation of the weaving machine, the warp yarns 2 are wound with 1, the rock 4 and healings 5 are formed to form a shed to the edge of the fabric 6 6. The fabric 7 moves through chest 3 and val 9 and winds onto the product roller 10. Technologic

The process of forming fabric 7 on a weaving loom is done with intensive work of its main mechanisms. When this work is done, a large amount of heat is released, which is discharged by cold water of the device 3 for moistening the warp threads 2. Cold water enters through the falling pipe 14 and the flexible lUJiaHi y 13 into the first tube 12 of the device 3 and has a temperature 5 ° C below the temperature of the point dew ambient air. The passage through the tubes 11 of the device 3, cold water cools the tubes 11 and, at the surface, 1 forms cooled air with increased relative humidity compared to the relative humidity of the surrounding air. Air is humidified by the interaction of air with condensate formed on the tubes 11 of the device 3 for moistening the warp threads 2. After heating in the tubes 11, water flows through the tube 14 through a flexible hose 16 and through a branch pipe 17 to a cooling system (not shown). The required air weave parameters at surface 1 and 1 are monitored by sensor 20. When air parameters increase near surface 1, sensor 20 sends a command to drive 19, which through means 18 moves device 3 closer to its 1 (in the drawing the position of device 3 and sensor 20 after moving is shown by a dashed line), which reduces the relative humidity and ambient temperature. The decrease in relative power occurs due to the fact that the cooled air reduces the formation of condensate on the tubes 11. When the parameters of the air are taken near the surface

The discharge device 3 moves from side to side 1. The air temperature in the gap A increases and to a greater extent contributes to the formation of condensate on the tubes 11 and an increase in the relative humidity of the air. The increase in relative humidity of the air causes the moistening of the threads

2 basis and increase lix strength, which reduces breakage of the main threads.
