Problems solved by technology

The traditional distribution tube is mostly designed in a straight line, and the size of the distribution tube is unchanged. First of all, this will keep the fabric in the same state during the movement in the distribution tube, and cannot expand in the weft direction. It is easy to form permanent creases, resulting in poor dyeing of the fabric; secondly, the linear design of the cloth tube makes the fabric always in a stretched state in the cloth tube, which cannot form a retraction process, and the internal stress cannot be released in time, which is easy Longitudinal creases are formed and the width of the fabric is narrowed; finally, the straight-line cloth tube fabric passes through it at a fast speed, and the effect of the secondary dyeing is poor, and it is impossible to form a retraction and weft expansion in the process of the secondary dyeing , especially for some fabrics that are sensitive to creases, creases are easy to occur when dyeing

Embodiment 1

[0024] Such as Figure 1-4 As shown, the wave-and-expanding cloth-running pipe of a dyeing machine in this embodiment includes a pipe body 10 provided with a cloth inlet 11 and a cloth outlet 12, and the pipe body 10 is arranged in a wave form on the dyeing machine. Inside, the cross section of the pipe body 10 is rectangular or oblong, the side a of the rectangle is gradually lengthened from the cloth inlet 11 to the cloth outlet 12, and the side b of the rectangle is gradually shortened from the cloth inlet 11 to the cloth outlet 12; The circular arc c is gradually lengthened from the cloth inlet 11 to the cloth outlet 12, and the oblong arc d is gradually shortened from the cloth inlet 11 to the cloth outlet 12. There is dye liquor flowing from the cloth inlet 11 to the cloth inlet 12 in the pipe body 10. If the inside is always in a bundle, the probability of forming creases on the longitudinal surface of the fabric is very high, and the dyeing effect at the folds is also...

Embodiment 2

[0027] Such as Figure 1-4 As shown, this embodiment improves the length ratio of the side a and side b of the cloth inlet 11 and the cloth outlet 12, and the length of the side a of the cloth outlet 12 is 1.5-2.5 times the length of the side a of the cloth inlet 11. The length of the 11 sides b of the cloth inlet is 1.5-2.5 times the length of the 12 sides b of the cloth outlet. In addition, this embodiment improves the length ratio of the cloth inlet 11 and the cloth outlet 12 arc c and arc d, and the length of the cloth inlet 12 arc c is 1.5-2.5 times the length of the cloth inlet 11 arc c. The length of the cloth inlet 11 arc d is 1.5-2.5 times of the length of the cloth outlet 12 arc d.

Embodiment 3

[0029] Such as figure 1 , 2 3. The fabric passes through the pipe body 10 shown in 3, and the fabric enters the pipe body 10 along the cloth inlet 11 and comes out from the cloth outlet 12. A rear nozzle 20 is arranged below the cloth inlet 11, and the rear nozzle 20 Spray the dye solution obliquely upwards along the direction of fabric movement. The rear nozzle 20 sprays water obliquely upward towards the bottom surface of the fabric, and the fabric produces a warp-stretching force, so that the state of the fabric in the cloth-running pipe changes from the retracted state expanded in the weft direction to the longitudinally stretched state, and then The upward spraying force of the nozzle makes the fabric have a process of free fall after being thrown, and in this process the fabric is in a state of free stretching without external force. Weft expansion and retraction achieve better results, and the fabric is expanded from the cloth outlet 12 after weft expansion. In this ...

Abstract

The invention relates to a wave-expanding type cloth conveying tube of a dyeing machine. The wave-expanding type cloth conveying tube comprises a tube body which is provided with a cloth inlet and a cloth outlet. The tube body is designed in a wave shape and expands gradually in width. Under a water flow characteristic of dye liquor, fabric is enabled to expand and retract in a weft direction greatly, and through tension and relaxation and changing states of the fabric, internal stress of the fabric can be released effectively, so that a folding mark cannot exist permanently at a same position, dyeing quality is improved, dyeing efficiency is increased, dyed fabric is good in hand feel and small in breadth variation, quantity of stentering and shaping in a following process is reduced, dyeing adaptability to folding mark sensitive fabric is improved, and application range of the dyeing machine is wider.

Description

[0001] 【Technical field】 [0002] The invention relates to a distribution pipe, in particular to a wave gradually expanding type distribution pipe of a dyeing machine. [0003] 【Background technique】 [0004] The dyeing machine has many uses, and can be used for dyeing, bleaching, scouring and washing of various pure cotton, chemical fiber fabrics and interwoven and blended fabrics. It is a kind of bleaching and dyeing equipment with a wide range of applications. The dyeing machine will be equipped with a cloth tube to realize the circulation of the fabric in the dyeing vat. The traditional distribution tube is mostly designed in a straight line, and the size of the distribution tube is unchanged. First of all, this will keep the fabric in the same state during the movement in the distribution tube, and cannot expand in the weft direction. It is easy to form permanent creases, resulting in poor dyeing of the fabric; secondly, the linear design of the cloth tube makes the fabri...
