Technical Field

[0001] The invention relates to a low-tension overflow swing bucket structure and a dyeing machine with the structure, belonging to the technical field of dyeing and finishing equipment. Background Art

[0002] With the development of knitted fabric looms and spinning technology, combined with the higher process requirements of the market, some high-density cotton-based knitted fabrics, when dyeing these fabrics, the traditional dyeing machine has too much tension during operation, resulting in insufficient relaxation of the fabric curling edge or the fabric edge cannot be unfolded. In the long-term dyeing process, the bleaching and dyeing are not sufficient, and the folded part of the fabric is not replaced in time, resulting in color difference in the edge, fish scale print on the edge, etc. After analysis, the excessive tension caused by the operation of the traditional dyeing machine mainly comes from two parts: 1. The cylinder head of the traditional dyeing machine is too high, resulting in too high a fabric lifting height; 2. The structure of the traditional swing bucket is too straight and the drop is too small. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solution described in the present application is described in a non-limiting manner below in conjunction with the accompanying drawings and embodiments.

[0017] like Figure 1-2As shown, the swing bucket structure of low tension overflow described in the present application includes a swing bucket body 11, a nozzle outer body 8, the nozzle outer body 8 has an independent cavity 7, a nozzle device 9 and a rotating bracket 10, and the nozzle device 9 is arranged in the cavity of the nozzle outer body 8. The swing bucket body 11 is formed into three sections: the straight pipe section 12 extends downward at an angle A, the curved pipe section 13 extends upward at an angle B, and the outlet section 14 extends downward at an angle C, and the center height F of the outlet section 14 is greater than the height D of the inlet section. Preferably, the angle A ranges from 10° to 15°, the angle B ranges from 45° to 50°, and the angle C ranges from 10° to 20°.

[0018] like Figure 1 The dyeing machine with low-tension overflow swing bucket structure described in the present application comprises a cylinder body 5, and the dyeing machine is provided with a lifting roller 1, a water inlet pipe 2, a swing device 3, a cylinder screen 6 and the low-tension overflow swing bucket structure 4. The lifting roller 1 is welded in the cylinder body, and the center position of the lifting roller 1 is slightly lower than the center position of the nozzle outer body inlet of the swing bucket structure 4, the outlet section of the swing bucket structure extends into the cylinder screen 6, the straight pipe section 12 of the inlet of the swing bucket body 11 is fixedly connected and matched with the nozzle outer body 8, and the outlet section 14 extends into the cylinder screen 6; the rotating bracket 10 is assembled and matched with the nozzle outer body 8, and is placed at the bottom of the nozzle outer body 8 and cooperates with the swing device 3 to jointly support the swing bucket to make a circular motion at a certain angle.

[0019] The working principle of the dyeing machine described in the present invention application is as follows: the dye liquid is driven by a high-pressure water pump through a water inlet pipe to drive the fabric that enters the outer body cavity of the nozzle through a lifting roller structure at the same time, and then flows into the swing bucket body, and is accelerated by the straight pipe section of the fabric guide pipe. Under the action of the high-pressure dye liquid dragging, the fabric is stretched to the maximum extent; the fabric and the dye liquid enter the upward curved pipe section at high speed, and the speed of the dye liquid and the fabric is slowed down by the large angle height difference, so that the fabric is stretched, alternated and transposed, and the purpose of thorough dyeing and uniform dyeing is further achieved; after being buffered and stretched by the curved pipe section, the dye liquid and the fabric are expanded again in the outlet section through the bell-mouth structure, so that the dye liquid is sieved to the inside of the cylinder. During the entire cyclic dyeing process, the fabric is fully wetted by the overflow phenomenon of the fluid in the swing bucket, and then the swing device is used to neatly stack the fabric in the cylinder for screening.

[0020] It should be understood that the above content including the drawings are not limitations of the technical solution. In fact, any improvements to the technical solution based on the same or similar principles, including changes in the size, shape, and materials used in the structure, and replacement of functionally similar components, are all within the technical solution claimed for protection in this application.
