Description

Technical Field

[0001] This utility model belongs to the field of nozzle technology, and relates to an overflow dyeing machine nozzle, particularly an overflow dyeing machine nozzle for fabrics. Background Technology

[0002] An overflow dyeing machine is a device used for dyeing textiles. The nozzle is one of its key components, used to spray dye or dye solution onto the textiles.

[0003] In traditional overflow dyeing machines, fabrics are circulated, squeezed, and folded in nozzles and pipes for a long time in a tight rope-like form. For high-density, microfiber fabrics, the structure is even tighter and lacks elasticity, making them prone to creases. Once creases are formed, they are difficult to remove in subsequent processes, thus solidifying into permanent dead creases or radial straight wrinkles. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an overflow dyeing machine nozzle for fabrics. The technical problem this invention aims to solve is: how to prevent high-density and microfiber fabrics from forming creases during the dyeing process.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A nozzle for an overflow dyeing machine for fabrics includes a nozzle body, a mixing chamber inside the nozzle body, a guide tube fixed at one end of the nozzle body, a relaxation chamber fixed at the other end of the guide tube, and a plurality of air inlet pipes fixed on the outer cylindrical surface of the relaxation chamber.

[0007] The working principle of this invention is as follows: The rope-like fabric enters the relaxation chamber, and air enters the relaxation chamber along the air inlet pipe. The rope-like fabric is constrained by the relaxation chamber, becoming shorter and thicker, minimizing its rope-like shape. It mixes with the injected air, ensuring that the fabric can stably wrap a certain amount of air, which plays a role in lubrication and buffering, making the rope-like fabric soft and relaxed. This prevents the rope-like fabric from becoming taut during subsequent dyeing. The loose fabric will wrap a certain amount of air. When this air-carrying fabric enters the nozzle body and is impacted by the dye liquor, the air forms a gas-liquid mixture film between the fabric and the inner wall of the nozzle body, reducing direct friction and compression. At the same time, the air can absorb and buffer some mechanical stress, making the fabric more gentle under force. Moreover, due to the presence of air, the shape of the fabric is not fixed. Under the turbulent impact of the dye liquor, it is more likely to roll, twist, and displace, thus avoiding the formation of creases in high-density and microfiber fabrics during the dyeing process. Then it enters the guide tube, and after being untwisted by the guide tube, it enters the overflow chamber inside the nozzle body.

[0008] A horn guide is fixed at the other end of the relaxation chamber.

[0009] Using the above structure, the movement of the rope-like fabric is guided and relaxed, increasing the softness and relaxation of the rope-like fabric in advance, thus achieving a pretreatment effect.

[0010] The nozzle body has a sway tube fixed at the bottom and a conical tube fixed at the top, with multiple injection tubes fixed at the top of the conical tube.

[0011] With the above structure, the dye liquor enters the conical tube along the injection tube and then enters the overflow chamber inside the nozzle body. The fabric inside the overflow chamber is mixed with the fabric and air under the high-speed impact of the dye liquor, and after strong penetration into the fabric, it is driven to be sprayed out along the spreading tube and enters the dyeing vat to complete one dyeing process.

[0012] It also includes a cylinder, which is fixed to the top of a tapered tube. A tapered plug slides inside the tapered tube, and a cylinder rod is fixed to the top of the tapered plug. The other end of the cylinder rod slides inside the cylinder.

[0013] Using the above structure, the cylinder rod is moved by the operation of the cylinder, which in turn drives the cone plug to slide inside the cone tube, thereby adjusting the size of the liquid outlet of the cone tube, and thus changing the liquid discharge force and flow rate of the cone tube, which facilitates the dyeing of different fabrics.

[0014] Compared with existing technologies, the overflow dyeing machine nozzle for this fabric has the following advantages:

[0015] 1. In this invention, a rope-like fabric enters the relaxation chamber, while air enters the relaxation chamber along the air inlet pipe. The rope-like fabric is constrained by the relaxation chamber, becoming shorter and thicker, minimizing its rope-like shape. It mixes with the injected air, ensuring that the fabric can stably wrap a certain amount of air, providing lubrication and cushioning. This makes the rope-like fabric soft and relaxed, preventing it from becoming taut during subsequent dyeing. The loose fabric will wrap a certain amount of air. When this air-carrying fabric enters the nozzle body and is impacted by the dye liquor, the air forms a gas-liquid mixture film between the fabric and the inner wall of the nozzle body, reducing direct friction and compression. At the same time, the air can absorb and buffer some mechanical stress, making the fabric more gentle under stress. Furthermore, due to the presence of air, the shape of the fabric is not fixed, and it is more likely to roll, twist, and shift under the turbulent impact of the dye liquor, thus avoiding creases in high-density and microfiber fabrics during the dyeing process.

[0016] 2. This utility model uses a cylinder to drive the cylinder rod to move, which in turn drives the cone plug to slide inside the cone tube, thereby adjusting the size of the liquid outlet of the cone tube, and thus changing the liquid discharge force and flow rate of the cone tube, which facilitates the dyeing of different fabrics.

Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figures 1-3 As shown, the nozzle of the overflow dyeing machine for this fabric includes a nozzle body 401. A mixing chamber is provided inside the nozzle body 401. A guide tube 301 is fixed at one end of the nozzle body 401, and a relaxation chamber 201 is fixed at the other end of the guide tube 301. Multiple air inlet pipes 202 are fixed on the outer cylindrical surface of the relaxation chamber 201.

[0023] The rope-like fabric enters the relaxation chamber 201, while air enters the relaxation chamber 201 along the air inlet pipe 202. The rope-like fabric, constrained by the relaxation chamber 201, becomes shorter and thicker, minimizing its rope-like shape. It mixes with the injected air, ensuring the fabric stably encapsulates a certain amount of air, providing lubrication and cushioning. This makes the rope-like fabric soft and relaxed, preventing it from becoming taut during subsequent dyeing. The loose fabric traps a certain amount of air, which, when it enters the nozzle body 401, is... During the dye liquor impact, air forms a gas-liquid mixture film between the fabric and the inner wall of the nozzle body 401, reducing direct friction and compression. At the same time, the air can absorb and buffer some mechanical stress, making the fabric more gentle on the force. Also, due to the presence of air, the shape of the fabric is not fixed, and it is easier to roll, twist and displace under the turbulent impact of the dye liquor, thus avoiding the formation of creases in high-density and microfiber fabrics during the dyeing process. Then it enters the guide tube 301, and after being untwisted by the guide tube 301, it enters the overflow chamber inside the nozzle body 401.

[0024] A horn guide 101 is fixed at the other end of the relaxation chamber 201.

[0025] In this embodiment, the movement of the rope-like fabric is guided and relaxed to increase its softness and looseness, thus achieving a pretreatment effect.

[0026] The nozzle body 401 is fixedly provided with a swaying tube 402 at the bottom end, and a conical tube 403 is fixedly provided at the top end of the nozzle body 401, and a plurality of injection tubes 404 are fixedly provided at the top end of the conical tube 403.

[0027] In this embodiment, the dye liquor enters the conical tube 403 along the injection pipe 404, and then enters the overflow chamber inside the nozzle body 401 along the conical tube 403. The fabric inside the overflow chamber is mixed with the fabric and air under the high-speed impact of the dye liquor, and after strong penetration of the fabric, it drives the fabric to be sprayed out along the spreading pipe 402 and enters the dyeing vat to complete one dyeing process.

[0028] It also includes a cylinder 406, which is fixed to the top of a tapered tube 403. A tapered plug 405 slides inside the tapered tube 403. A cylinder rod 407 is fixed to the top of the tapered plug 405, and the other end of the cylinder rod 407 slides inside the cylinder 406.

[0029] In this embodiment, the cylinder 406 drives the cylinder rod 407 to move, which in turn drives the cone plug 405 to slide inside the cone tube 403, thereby adjusting the size of the liquid outlet of the cone tube 403, and thus changing the liquid discharge force and flow rate of the cone tube 403, which facilitates the dyeing of different fabrics.

[0030] The working principle of this utility model:

[0031] First, the rope-like fabric arrives from the dyeing vat, is collected, guided, and relaxed by the trumpet guide 101, and then enters the relaxation chamber 201 along the trumpet guide 101. Simultaneously, air enters the relaxation chamber 201 along the air inlet pipe 202. The rope-like fabric is constrained and reduced in size by the relaxation chamber 201, becoming shorter and thicker, minimizing its rope-like shape. It then mixes with the injected air and enters the guide tube 301. After being untwisted through the guide tube 301, it enters the overflow chamber inside the nozzle body 401 and is then passed through the cylinder 40... 6. The working mechanism pushes the cylinder rod 407 to move, which in turn drives the cone plug 405 to slide inside the cone tube 403. After adjusting the size of the outlet of the cone tube 403, the dye liquor enters the cone tube 403 along the injection pipe 404 and enters the overflow chamber inside the nozzle body 401 along the cone tube 403. The fabric inside the overflow chamber is mixed with the fabric and air under the high-speed impact of the dye liquor, and after strong penetration of the fabric, it is driven to be sprayed out along the spreading pipe 402 and enter the dyeing vat to complete one dyeing process.

[0032] In summary, by setting up the horn guide 101 and the relaxation chamber 201, the rope-like fabric coming from the dyeing vat is constrained and reduced in size, becoming shorter and thicker, thus minimizing its rope-like shape. It mixes with the injected air, ensuring the fabric can stably contain a certain amount of air, providing lubrication and cushioning. This makes the rope-like fabric soft and relaxed, preventing it from becoming taut during subsequent dyeing. The loose fabric traps a certain amount of air. When this air-carrying fabric enters the nozzle body 401 and is impacted by the dye liquor, the air forms a gas-liquid mixture film between the fabric and the inner wall of the nozzle body 401, reducing direct friction and compression. Simultaneously, the air absorbs and buffers some mechanical stress, making the fabric more gently stressed. Furthermore, due to the presence of air, the fabric's shape is not fixed; it is more prone to tumbling, twisting, and displacement under the turbulent impact of the dye liquor, thus preventing creases from forming in high-density and microfiber fabrics during the dyeing process.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
