Description

Technical Field

[0001] The invention belongs to the technical field of textile printing and dyeing equipment, and in particular relates to a connection device for a cloth hopper and a pipe of a dyeing machine. Background Art

[0002] The fabric is dyed in the dyeing machine by circulating through the cloth bucket at the bottom of the dye vat, the cloth lifting wheel, the nozzle, and the cloth passing tube on the top, thus achieving a continuous dyeing process.

[0003] When the fabric passes through the fabric tube and falls to one end of the arc-shaped fabric bucket, it automatically slides along the bottom of the fabric bucket to the end below the fabric lifting wheel under the action of gravity. Since the pipe is a Teflon tube, it has good physical properties such as high temperature resistance, corrosion resistance, and low friction coefficient. The bottom of the fabric bucket is made of many Teflon round tubes arranged in an array. This fabric bucket structure is suitable for low friction sliding of fabrics in a highly corrosive high-temperature dyeing environment, and can also achieve a very good cloth-liquid separation effect. During the dyeing process, when the fabric stacked on the Teflon tube slides from left to right, a large amount of water or dye carried by the fabric can quickly flow down to the bottom of the cylinder at the gap and enter the dye circulation system. However, the sensitivity of the dyed fabric to other contact objects during the sliding movement makes the middle section support structure of the Teflon tube and its installation and fixation a problem. The traditional middle section fixed support is either made of 316 steel plates with good corrosion resistance to cut arc grooves, but the thin plate is prone to yarn clamping, yarn scraping or abrasion on the surface of the fabric hanging down to the gap of the Teflon tube, seriously affecting the dyeing quality of the fabric; or it is cut and formed by solid 316 stainless steel square steel. Since the material is expensive and the cost is very high, and all surface edges and corners must be arc transitions, the processing is difficult and the cycle is long, and the processing cost is also very high.

[0004] Therefore, it is necessary to develop a dyeing machine cloth hopper pipe connection device to solve the above technical problems. Summary of the invention

[0005] In view of the above problems, the present invention provides a dyeing machine cloth bucket pipe connection device for solving the technical problem that the pipe support in the prior art is prone to yarn clamping, yarn scraping or abrasion, which seriously affects the fabric dyeing quality.

[0037] The specific working principle of the present invention is:

[0038] The bottom of the cloth hopper of the dyeing machine is arranged with a Teflon tube body 3. The high temperature resistance, corrosion resistance and low friction coefficient of the Teflon material can achieve low friction sliding of the fabric and good cloth-liquid separation effect during the dyeing process.

[0039] The middle section of the tube body 3 is fixed by a forming support 6, which is formed in one step by a thin plate and has an arc groove surface 61, a center hole 62 and a U-shaped groove 63, ensuring a close fit with the tube body 3 without gaps or edges to avoid fabric damage.

[0040] An inner sleeve made of stainless steel is arranged inside the tube body 3 to maintain the bending radius and shape of the tube, and at the same time, the Teflon tube is fixed and adjusted by means of a plug and a screw.

[0041] The upper end and the lower end of the tube body 3 are fixed by an upper tube end support assembly 4 and a lower tube end support assembly 5 respectively, so as to ensure the stability and position accuracy of the tube body 3 .

[0042] Specific working process:

[0043] Installation of the tube body 3: A Teflon tube body 3 curved in an arc shape is arranged within a certain height range at the upper right bottom of the dye vat body, and is connected to the thin plate 53 on the left (see Figure 4 ) are connected to form a cloth containing bucket, and the thin plate 53 is a Teflon thin plate.

[0044] Setting forming supports: above the middle section of the tube body 3, forming supports 6 are set at intervals as required, and a support plate 2 is welded below each forming support along the length direction and is welded and fixed to the bottom of the cylinder body.

[0045] Fixing of the pipe body 3: The upper end and the lower end of the pipe body 3 are fixed by an upper pipe end bracket assembly 4 and a lower pipe end bracket assembly 5 respectively, so as to ensure the stability of the pipe arrangement.

[0046] Adjustment of the inner sleeve and the plug 34: An inner sleeve is arranged throughout the entire length of the tube body 3, and the end of the inner sleeve 33 at the upper end is provided with a plug 34. The plug 34 is provided with a screw 35, and the extended length of the screw 35 is fixed or adjusted by a nut to maintain the bending radius of the tube body 3.

[0047] Fabric dyeing process: The fabric falls into the arc-shaped fabric bucket through the fabric pipe, and slides along the Teflon tube to the bottom of the fabric lifting wheel. During this process, the water or dye on the fabric quickly flows down to the bottom of the tank through the gap of the tube body 3 and enters the dye circulation system.

[0048] The design of the tube body 3 and the forming support 6 ensures that there is no direct contact between the fabric and the support, reducing fabric damage and promoting fabric-liquid separation and water liquid reflux.

[0049] The present application improves the dyeing efficiency and fabric quality of the dyeing machine through its unique support and fixing method, while simplifying the maintenance and adjustment process of the equipment.
