Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing equipment technology, and in particular to an anti-swirling nozzle structure and a dyeing machine. Background Technology

[0002] With rapid economic development and increasing production demands in the textile industry, dyeing and printing equipment is constantly being updated and iterated at the technological level, placing higher requirements on the dyeing quality and efficiency of fabrics. During the dyeing process, the dye liquor is typically introduced into the dyeing machine through a supply system and then sprayed onto the fabric surface via a spraying assembly to achieve uniform dyeing.

[0003] However, when the dye liquor enters the supply channel inside the dyeing machine from the supply pipeline, it is easy to generate a swirling phenomenon during the flow process. When the swirling dye liquor enters the spray hole, the sprayed dye liquor will be unevenly sprayed, which will further affect the quality of the dyed fabric and make it difficult to meet the demand of modern textile industry for high-quality dyeing. Utility Model Content

[0005] To achieve this objective, the following technical solution is adopted in this application: This application provides an anti-swirling nozzle structure, which includes an outer cylinder, a nozzle assembly, a liquid distribution ring, and several flow dividers, wherein: The outer cylinder is installed around the nozzle assembly, and an annular liquid supply channel is formed between the outer cylinder and the nozzle assembly. A liquid supply port communicating with the liquid supply channel is opened at the bottom of the outer cylinder. The nozzle assembly has a dyeing channel through which the fabric is fed. The nozzle assembly is provided with an annular spray hole that communicates with the dyeing channel. The spray hole connects the dyeing channel and the supply channel. The dye enters the supply channel through the supply port and is then sprayed out through the spray hole onto the fabric in the dyeing channel.

The dye liquid in the liquid supply channel enters between the first nozzle and the second nozzle through the notches and is sprayed out from the spray hole. The straight cylinder is inserted through the liquid distribution ring and the outer wall of the straight cylinder is sealed to the inner ring of the liquid distribution ring. The straight cylinder is sleeved at the bottom of the second nozzle and the outer wall of the bottom end of the second nozzle is sealed to the inner wall of the inlet end of the straight cylinder.

A liquid supply port 12 communicating with the liquid supply channel is opened at the bottom of the outer cylinder 10. The nozzle assembly 20 has a dyeing channel 21 through which the fabric is fed. The nozzle assembly 20 is provided with an annular spray hole 22 that communicates with the dyeing channel 21. The spray hole 22 connects the dyeing channel 21 and the supply channel 11. The dye liquid enters the supply channel 11 through the supply port 12 and is sprayed out through the spray hole 22 onto the fabric in the dyeing channel 21. The liquid distribution ring 30 is disposed inside the liquid supply channel 11 and is fixedly connected to the inner wall of the outer cylinder 10. The liquid distribution ring 30 is provided with a number of through holes 31. The spray hole 22 is located above the liquid distribution ring 30. A number of flow dividers 40 are disposed in the liquid supply channel 11 along the circumferential direction and above the liquid distribution ring 30. The flow dividers 40 are configured to divide the dye liquor passing through the through holes 31.

[0023] By setting a liquid distribution ring 30 with through holes 31 and several flow dividers 40 in the liquid supply channel 11, the dye liquid is diverted after passing through the through holes 31 of the liquid distribution ring 30 and then comes into contact with the flow dividers 40, thereby achieving secondary diversion, effectively suppressing swirling flow and improving the uniformity of liquid spraying.

[0024] In one embodiment, the nozzle assembly 20 includes a first nozzle 23, a second nozzle 24, a straight cylinder 25, and a support ring 26 arranged coaxially, wherein: The support ring 26 is connected to the inner wall of the outer cylinder 10 in the horizontal direction.

The bottom of the first nozzle 23 and the inner wall of the second nozzle 24 are set with a preset distance to form an adjustable spray hole. The side of the second nozzle 24 has several notches. The dye liquid in the liquid supply channel 11 enters between the first nozzle 23 and the second nozzle 24 through the notches and is sprayed out from the spray hole 22.

The straight cylinder 25 is sleeved on the bottom of the second nozzle 24 and the outer wall of the bottom end of the second nozzle 24 is sealed to the inner wall of the inlet end of the straight cylinder 25.

[0025] Specifically, the inlet end of the straight cylinder 25 is cone-shaped with its outer diameter extending from the outside to the inside, which facilitates the bottom of the second nozzle 24 to pass through.

[0027] The cooperation of the first nozzle 23, the second nozzle 24, and the support ring 26 facilitates the formation of an adjustable spray hole 22. At the same time, the cooperation with the straight cylinder 25 enables the adjustment of the size of the spray hole 22 and the stable sealing of the spray path, thereby improving the adaptability and operational stability of the mechanism.

[0032] In one embodiment, a plurality of flow dividers 40 are evenly spaced along the circumferential direction and each flow divider 40 is arranged radially toward the nozzle assembly 20.

[0033] By evenly spaced the diverter plates 40 along the circumference and facing the nozzle assembly 20, the dye liquor is further evenly divided in the supply channel 11, thereby further weakening the swirling trend and ensuring the stability of the dye liquor at the spray nozzle.
