Description

Technical Field

[0001] The utility model relates to a dyeing machine with a low-tension cloth guiding tube and a tile-type cylinder inner sieve structure, belonging to the technical field of dyeing and finishing equipment. Background Technique

[0002] With the development of textile technology, the market has higher and higher requirements for process requirements such as the dyeing uniformity of fabrics. In particular, for problems such as creases, indentations, fish scale prints, and uneven dyeing that frequently occur during the dyeing of cotton fabrics. When traditional dyeing machines dye cotton fabrics, due to problems such as excessive running tension and cloth clamping, the fabric hemming is not loose enough or the cloth edge cannot be unfolded, the boiling, bleaching, and dyeing are not sufficient, and the folding and clamping parts of the fabric are not replaced in time, resulting in problems such as edge-middle color difference and fish scale prints on the cloth edge.

[0003] Through structural and experimental analysis, the reasons mainly come from two parts: one is the traditional cloth guiding tube, whose structure mostly extends horizontally or slightly downward, and the outlet end directly faces downward towards the inside of the cloth storage tank. This type of cloth guiding tube structure often causes problems such as insufficiently loose fabric hemming and untimely replacement due to excessive tension, resulting in creases, uneven dyeing, etc. The other is the traditional Teflon roller type cylinder inner sieve structure, which is prone to cloth clamping during dyeing, thus causing problems such as creases and uneven dyeing; while the existing steel plate sieve, although it solves the problem of cloth clamping during dyeing to a certain extent, also causes problems such as cloth surface indentation due to excessive friction between the cloth surface and the steel plate sieve and small water return rate, and the bath ratio is too large, violating the concept of "energy conservation and emission reduction". Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a dyeing machine with a low-tension cloth guiding tube and a tile-type cylinder inner sieve structure, which has technical advantages such as a low bath ratio and low tension, solves problems such as cloth surface creases, indentations, fish scale prints, and uneven dyeing encountered during the dyeing process of fabrics, thereby achieving the purpose and effect of circular and uniform dyeing, and further improving the dyeing quality.

[0005] The utility model is realized according to the following technology:

[0006] A dyeing machine with a low-tension cloth guiding tube and a tile-type cylinder inner sieve structure, characterized in that: the low-tension cloth guiding tube includes a cloth guiding tube body, and the input end of the cloth guiding tube body is connected to the nozzle housing; a nozzle device is arranged inside the nozzle housing; the output end of the cloth guiding tube body is connected to the flange of the cylinder body and flows towards the inner tail sieve of the cylinder; the nozzle housing is connected to the cylinder head; the low-tension cloth guiding tube extends from the nozzle housing in sequence from near to far as a small-diameter inlet straight tube section extending horizontally downward, a partial cone section extending horizontally upward, and a bent tube outlet section extending downward and bending to enter the inner tail sieve of the cylinder. A guiding tongue plate is arranged inside the partial cone section and the bent tube outlet section; the tile-type cylinder inner sieve includes a tile-type cylinder inner sieve plate body. The front end of the tile-type cylinder inner sieve plate body along the fabric conveying direction is connected to the inner tail sieve of the cylinder, and the rear end of the tile-type cylinder inner sieve plate body along the fabric conveying direction is connected to the inner wall of the cylinder body; the connection between the tile-type cylinder inner sieve plate body and the inner tail sieve of the cylinder is a straight-section steel plate, and the connection between the tile-type cylinder inner sieve plate body and the inner wall of the cylinder body is an arc-shaped continuous tile-type sieve plate; a plurality of water leakage holes are arranged at the bottom of the tile-type sieve plate.

[0007] The technical solutions for further limiting the present invention include:

[0008] Flange structures are arranged at both the input end and the output end of the low-tension cloth guiding tube. The flange at the input end is connected to the flange of the nozzle housing, and a nozzle device is arranged inside the nozzle housing; the flange at the output end is connected to the flange of the cylinder body and flows towards the inner tail sieve of the cylinder.

[0009] For the small-diameter inlet straight tube section, the included angle of the horizontal downward extension is 5°-25°; for the partial cone section, the included angle of the horizontal upward extension is 5°-30°, and its installation direction is from small-diameter input to large-diameter output; the bent tube outlet section extends downward and flows towards the inner tail sieve of the cylinder, and its angle is 30°-90°.

[0010] A guiding tongue plate is arranged inside the partial cone section and the bent tube outlet section. The front end of the guiding tongue plate forms an included angle of 20°-70° with the installation of the partial cone section, and the rear end is connected to the flange at the output end of the cloth guiding tube, forming a cross-section and an upward climbing structure, and bending downward to enter the inner tail sieve of the cylinder.

[0011] The front end of the tile-type cylinder inner sieve plate along the fabric conveying direction is a straight-section steel plate connected to the inner tail sieve of the cylinder.

[0012] The rear end of the tile-type cylinder inner sieve plate along the fabric conveying direction is a continuous tile-type sieve plate with a certain arc and is connected to the inner wall of the cylinder body. The radian of the tile-type sieve plate is 45°-180°, the angle of the tile-type structure is 30°-120°, the wave height is 10-30 mm, the wave distance is 20-100 mm, and the overall tile-type structure design has a smooth transition at the fillet.

According to the difference in water absorption of the cloth types, the water leakage holes are arranged in a single row or multiple rows in parallel, and the diameter of the water leakage holes is 2.5-8 mm.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model has a reasonable structural design. With the help of a dye liquid flow with a certain pressure output by a nozzle device, the fabric in the cavity of the nozzle device is driven to enter the low-tension cloth guide pipe, and is successively input from the small-diameter inlet straight pipe section to the partial cone section with a guide tongue plate and the bent pipe outlet section. In this process, due to the changes in cross-section and height difference, a dye liquid flow with a low tension effect is formed, so that the fabric obtains a larger space for stretching, alternation and transposition when passing through the cloth guide pipe, and enters the tail screen in the cylinder in an orderly manner.

[0016] Furthermore, driven by the dye flow, the fabric enters the sieve plate in the tile-type cylinder, and is first decelerated at a certain length of straight steel plate. Then, due to the special tile-type structure, the contact area between the cloth and the sieve plate is effectively reduced, thereby reducing the friction between the two, allowing the fabric to be circulated and dyed in a more orderly manner. Furthermore, under the action of gravity, the dye on the cloth uses the leakage holes at the bottom of the sieve plate in the tile-type cylinder to flow back to the bottom of the cylinder, thereby achieving the purpose and effect of circulating and uniform dyeing with minimal energy consumption, and implementing the concept of "energy conservation and emission reduction".

[0017] The above structures cooperate with each other to effectively solve the technical deficiencies of the cloth guide pipe and the screen structure in the cylinder of the traditional dyeing machine, so as to solve the problems of cloth creases, indentations, uneven dyeing, etc. encountered in the dyeing of the fabric with a low bath ratio of dye liquid, thereby improving the dyeing quality.

[0024] The technical solution of the present utility model will be described non-restrictively below in conjunction with the accompanying drawings and implementation cases.

[0025] As Figure 1 shown, a dyeing machine with a low-tension cloth guiding pipe and a tile-shaped sieve plate structure inside the cylinder includes a cylinder body barrel 01, a cylinder body barrel flange 011, a cylinder head 02, a nozzle housing 03, a nozzle device 031, a nozzle housing flange 032, a cloth guiding pipe 04, a tail sieve 05 inside the cylinder, and a tile-shaped sieve plate 06 inside the cylinder.

[0026] As Figure 1-2 shown, the structure of the low-tension cloth guiding pipe 04 includes an input end flange 041 connected to the nozzle housing flange 032; an inlet straight pipe section 042 with a small diameter b extending horizontally downward, preferably, the horizontal downward angle a is 5° - 25°; a tapered section 043 extending horizontally upward, with its installation direction being from a small diameter b input to a large diameter e output, preferably, the upward horizontal extension angle c is 5° - 30°; an elbow outlet section 044 extending outwards from the tapered section 043, preferably, the angle f is 30° - 90°; a guide tongue plate 045 is arranged inside the tapered section 043 and the elbow outlet section 044, preferably, the front end of the guide tongue plate 045 forms an installation angle d of 20° - 70° with the tapered section 043, and the rear end is connected to the output end flange 046 of the cloth guiding pipe 04, forming a cross-section and an upward climbing structure, and extending downward and leading into the tail sieve 05 inside the cylinder; the output end flange of the cloth guiding pipe 04 is connected to the cylinder body barrel flange 011.

[0027] As Figure 1 、 3, as shown in Figure 4, the corrugated inner cylinder sieve plate 06 includes a straight-section steel plate 061 connected to the inner cylinder tail sieve 05, a continuous corrugated sieve plate 062 with a certain arc, and a fixed support 063 that connects the entire corrugated inner cylinder sieve plate 06 to the inner wall of the cylinder body 01. Preferably, the overall arc t of the continuous corrugated sieve plate 062 is 45° - 180°, the corrugated structure angle w is 30° - 120°, the wave height h is (10 - 30) mm, and the wave pitch s is (20 - 100) mm; the overall corrugated structure is designed with a rounded corner r for smooth transition to prevent snagging of the fabric surface. Further, a number of water leakage holes are provided at the bottom of the corrugated inner cylinder sieve plate 06. According to the difference in water absorption of different fabric types, preferably, the water leakage holes are arranged in a single row or multiple rows in parallel, and the diameter φ of the water leakage holes is (2.5 - 8) mm.

[0028] The working principle of the present utility model is described as follows:

[0029] With the help of the dye liquor flow with a certain pressure output by the nozzle device 031, the fabric in the cavity of the nozzle device 031 is driven into the low-tension fabric guiding tube 04; further, the fabric obtains a certain acceleration in the horizontally downward extending inlet straight tube section 042 and is expanded outward to the maximum extent and conveyed to the horizontally upward extending partial cone section 043 and the downward extending elbow outlet section 044. During this process, due to the height difference change between the curved diameter of the elbow outlet section 044 and the partial cone section 043, and the cross-section change from a small diameter input to a large diameter output, a larger stretching space is provided for the fabric, so that the fabric and the dye liquor flow obtain a certain deceleration.

[0030] Further, the special cross-section low-tension dye liquor flow formed under the action of the upward climbing structure of the internal guiding tongue plate 045 enables the fabric to better stretch, alternate, and change positions in the fabric guiding tube 04 and enter the inner cylinder tail sieve 05 in an orderly manner.

[0031] Further, under the push of the dye liquor flow, the fabric passes through the straight-section steel plate 061 of the corrugated inner cylinder sieve plate 06 in sequence. With appropriate frictional force, the fabric is not washed too fast, so that the fabric enters the continuous corrugated sieve plate 062 with a certain arc more orderly. With the help of the special corrugated structure, the contact area between the fabric and the corrugated sieve plate is reduced, and the frictional force between the two is reduced;

[0032] Furthermore, the dye liquor on the fabric surface flows back to the bottom of the cylinder through a number of water leakage holes at the bottom of the corrugated inner cylinder sieve plate 06 under the action of gravity, improving the recycling utilization rate of the dye liquor, thereby achieving the purpose and effect of uniformly dyeing in a cycle with the minimum energy consumption and implementing the concept of "energy conservation and emission reduction".

[0033] The above structures cooperate with each other, effectively solving the technical deficiencies of the fabric guiding tube and the in-vat sieve structure of traditional dyeing machines, achieving the purpose of using a low liquor ratio of dye liquor to solve problems such as fabric surface creases, indentations, fish scale prints, and uneven dyeing during cyclic dyeing, thereby improving the dyeing quality.

[0034] Finally, it should be noted that the above content including the attached drawings is not a limitation on the technical solution. In fact, any improvement to the technical solution based on the same or similar principles, including changes in the size and shape of the structure, the materials used, and the replacement of functionally similar components, is within the technical solution claimed in the application of this utility model.
