Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dyeing machines, in particular to an overflow dyeing machine with uniform dyeing temperature. BACKGROUND

[0002] The overflow dyeing machine is a device used in the textile industry, mainly used for dyeing textile fabrics. The overflow dyeing machine uses the overflow principle to control the flow and temperature of the dyeing liquid, so that the dye penetrates uniformly into the fabric, realizing the dyeing of the fabric.

[0003] In related technologies, for example, a Chinese utility model patent with the publication number CN202139426U discloses an overflow dyeing machine, which comprises a main body, a dyeing chamber arranged in the main body, a cloth lifting wheel, a nozzle arranged above the main body, a circulating pipeline connecting the dyeing chamber and the inlet of the nozzle, a main pump arranged on the circulating pipeline, an outlet of a chemical tank connected with a feeding pipe, a dyeing fabric entering the dyeing chamber through the nozzle and moving circularly under the action of the cloth lifting wheel, a liquid storage tank arranged at the bottom of the main body and connected with the outlet of the chemical tank and the outlet of the dyeing chamber, and a preheating cylinder arranged on the circulating pipeline connecting the outlet of the liquid storage tank and the inlet of the nozzle.

[0004] However, after the dyeing liquid heated by the heat exchanger is used to dye the fabric, the temperature of the fabric will gradually decrease when the fabric moves in the dyeing machine, so that the subsequent fixation effect of the dyeing liquid on the fabric is poor, and the temperature of each part in the dyeing machine is not uniform, which is easy to cause color difference. SUMMARY

[0005] In order to improve the dyeing effect of the fabric in the overflow dyeing machine, the present application provides an overflow dyeing machine with uniform dyeing temperature.

[0006] The overflow dyeing machine with uniform dyeing temperature provided by the present application adopts the following technical scheme:

[0007] An overflow dyeing machine with uniform dyeing temperature, comprising an overflow dyeing machine body and a heat exchanger arranged on the machine body, the dyeing liquid enters the machine body after being heated by the heat exchanger, an overflow pipe is arranged on the machine body, the high-temperature dyeing liquid heated by the heat exchanger repeatedly overflows in the overflow pipe, a cloth lifting wheel is rotatably arranged in the machine body, the fabric passes through the overflow pipe for dyeing under the action of the cloth lifting wheel, a fixation device for fixing the dyed fabric is arranged on the machine body, and the fixation device comprises:

[0008] A fixation pipe is arranged on the machine body, and the fabric enters the fixation pipe after being dyed by the overflow pipe;

[0009] A high-pressure gas pipe is arranged on the fixation pipe, and the high-pressure gas pipe is used for spraying high-pressure gas to the fabric.

[0010] By adopting the technical scheme, the cloth enters the machine body, passes through the overflow pipe under the action of the cloth lifting wheel, the overflow dye in the overflow pipe dyes the cloth, the dyed cloth enters the fixing pipe, the high-pressure gas pipe sprays high-pressure gas to the cloth in the fixing pipe, and the dye on the cloth can further penetrate into the cloth, thereby improving the dyeing effect.

[0011] Optionally, one end of the high-pressure gas pipe is located outside the fixing pipe and communicates with the gas source, and an inclined high-pressure nozzle is arranged on the other end of the high-pressure gas pipe, and the gas outlet of the high-pressure nozzle is arranged towards the cloth outlet of the fixing pipe.

[0012] By adopting the technical scheme, an inclined high-pressure nozzle is fixed on the high-pressure gas pipe, so that the high-pressure gas sprayed by the high-pressure gas pipe can not only make the cloth dye more fully, but also blow the cloth to move, thereby enabling the cloth to move in a predetermined direction without the need to set a specific driving component, saving energy and protecting the environment.

[0013] Optionally, a heating mechanism for heating the cloth in the fixing pipe is arranged on the machine body, and the heating mechanism comprises:

[0014] A heating pipe is arranged on the machine body, one end of the heating pipe communicates with a heat exchanger, hot gas generated in the heat exchanger enters the heating pipe, and the other end of the heating pipe communicates with the inside of the fixing pipe.

[0015] A flow guide cover is arranged on the end of the heating pipe located in the fixing pipe, one end of the flow guide cover is in an open state, and the diameter of the opening of the flow guide cover is greater than the diameter of the connection with the heating pipe.

[0016] By adopting the technical scheme, the gas blown out by the high-pressure nozzle flows in the fixing pipe, when the gas flows along the outer sidewall of the flow guide cover from the side of the heating pipe, the pressure difference between the inside and outside of the heating pipe causes the hot gas in the inside of the heating pipe to flow out of the heating pipe, thereby heating the subsequent conveying space of the dyed cloth, so that the temperature of the cloth in the machine body can always be uniform and consistent, ensuring the dyeing effect of the cloth; and at the same time, the excess heat in the heat exchanger for heating the dye is utilized by the communication between the heating pipe and the heat exchanger, without the need to separately set a heat source, saving energy and protecting the environment.

[0017] Optionally, a driving assembly for secondarily driving the hot gas discharged from the heating pipe is arranged on the heating pipe, and the driving assembly comprises:

[0018] A driving fan wheel is arranged on the heating pipe.

[0019] A rotating shaft is arranged on the driving fan wheel.

[0020] A drive fan is mounted on a rotating shaft.

[0021] By adopting the above technical solution, when hot air flows out of the heating pipe, it comes into contact with the drive impeller. The drive impeller rotates under the action of the hot air, which drives the shaft to rotate. The shaft rotation drives the drive fan to rotate, and the drive fan rotation provides secondary drive for the hot air and the gas ejected from the high-pressure nozzle. This allows the fabric to continue moving along with the gas, reducing the probability that the gas will be insufficient to move the fabric as the distance between the fabric and the high-pressure nozzle increases, thus improving the fabric conveying effect. Furthermore, the fan's operation makes the hot air mix more evenly with the gas in the internal environment of the machine, resulting in a more uniform and constant temperature throughout the machine.

[0022] Optionally, the color-fixing tube is provided with a fixing component for fixing the heating tube, the fixing component including:

[0023] A retaining ring, which is sleeved on the heating tube;

The fixing bolt is screwed through the fixing plate and threaded onto the color-fixing tube, thereby completing the connection and fixing work between the heating tube and the color-fixing tube, reducing the probability of relative displacement between the heating tube and the color-fixing tube under the action of the internal and external air pressure difference.

[0028] Optionally, a spreading plate is provided on the color-fixing tube. The surface of the spreading plate is arc-shaped. After the fabric enters the color-fixing tube, it moves against the surface of the spreading plate under the action of high-pressure airflow. A spreading nozzle is provided on each side of the high-pressure nozzle, and the spreading nozzle is connected to the high-pressure air pipe.

[0029] By adopting the above technical solution, an arc-shaped spreading plate is fixed inside the color-fixing tube. After the fabric moves to the spreading plate, it is evenly spread along the surface of the arc-shaped spreading plate under the action of the high-pressure nozzle and the spreading nozzle. This allows the fabric surface to come into contact with the high-pressure gas, making the high-pressure gas more uniform when blowing the fabric to fix the color, thus improving the color-fixing effect.

[0030] Optionally, the color-fixing tube is provided with a protective component for protecting the rotating shaft, the protective component including:

[0031] A shaft sleeve is sleeved on the rotating shaft;

[0032] A stabilizing rod is arranged at one end on the shaft sleeve and connected at the other end to the inner tube wall of the fixing tube.

[0033] By adopting the above technical scheme, the stabilizing rod is fixed on the inner tube wall of the fixing tube, and the shaft sleeve sleeved on the rotating shaft is fixed on the stabilizing rod, so that the rotating shaft is protected, thereby reducing the probability of rusting of the rotating shaft in a long-term high-temperature and high-humidity environment and prolonging the service life of the rotating shaft.

[0039] Optionally, the rotating assembly comprises:

[0040] A driving wheel is rotationally arranged on the machine body.

[0060] Referring to Figure 2 and Figure 3 , the fixing device 2 comprises a fixing pipe 21 and a high-pressure gas pipe 22. The fixing pipe 21 is fixedly connected to the inside of the machine body 1 and located on the side, away from the overflow pipe 12, of the cloth lifting wheel 13. The cloth passes through the fixing pipe 21 after moving out of the cloth lifting wheel 13. The high-pressure gas pipe 22 is fixedly connected to the machine body 1, one end of the high-pressure gas pipe 22 is communicated with a gas source, and the other end of the high-pressure gas pipe 22 is connected with the upper surface of the fixing pipe 21 and communicated with the inside of the fixing pipe 21.

[0061] Referring to Figure 3 , one end of the high-pressure gas pipe 22 communicated with the inside of the fixing pipe 21 is fixedly connected with a high-pressure nozzle 23, and the high-pressure nozzle 23 is arranged in an inclined state. The gas outlet of the high-pressure nozzle 23 is inclined towards the end of the cloth moving out of the fixing pipe 21. The two sides of the high-pressure nozzle 23 are further fixedly connected with one cloth spreading nozzle 24 respectively.

[0062] Referring to Figure 3The inner bottom wall of the fixing tube 21 is fixedly connected with a spreading plate 25. The upper surface of the spreading plate 25 is arc-shaped, and the height of the middle part of the upper surface of the spreading plate 25 is higher than that of the two side edges. After the cloth enters the fixing tube 21, it is spread on the surface of the spreading plate 25 under the action of the high-pressure nozzle 23 and the two spreading nozzles 24. The dye liquid on the cloth further penetrates into the cloth under the action of the high-pressure gas, thereby enhancing the dyeing effect of the dye liquid, and at the same time, the cloth moves towards the cloth outlet of the fixing tube 21 under the action of the high-pressure gas.

[0063] With reference to Figure 2 and Figure 3 , the body 1 is provided with a heating mechanism 3 for heating the cloth. The heating mechanism 3 comprises a heating pipe 31 and a flow guide cover 32. The heating pipe 31 is fixedly connected to the body 1. One end of the heating pipe 31 is in communication with the inside of the heat exchanger 11, and the other end of the heating pipe 31 is connected to the upper surface of the fixing tube 21 and is in communication with the inside of the fixing tube 21. The flow guide cover 32 is fixedly connected to the end of the heating pipe 31 that is in communication with the inside of the fixing tube 21. The end of the flow guide cover 32 away from the heating pipe 31 is in an open state, and the diameter of the opening of the flow guide cover 32 is larger than that of the connection with the heating pipe 31. When the gas in the fixing tube 21 flows along the outer side wall of the flow guide cover 32 under the action of the high-pressure nozzle 23 and the spreading nozzle 24, the gas inside and outside the heating pipe 31 forms a pressure difference, and the hot gas inside the heating pipe 31 flows out of the heating pipe 31.

[0064] With reference to Figure 3 and Figure 4 , the heating pipe 31 is provided with a driving assembly 4 for secondary driving of the hot gas discharged from the heating pipe 31.

[0065] With reference to Figure 3 and Figure 4 , when the gas flow in the fixing tube 21 flows along the outer side wall of the flow guide cover 32 from the side of the driving fan wheel 41, a pressure difference is generated between the inside and outside of the heating pipe 31, causing the hot gas in the heating pipe 31 to flow out. The hot gas contacts the driving fan wheel 41 during the flow-out process and drives the driving fan wheel 41 to rotate. The rotation of the driving fan wheel 41 drives the rotating shaft 42 to rotate, and the rotation of the rotating shaft 42 drives the driving fan 43 to rotate. The rotation of the driving fan 43 drives the hot gas and the gas discharged from the high-pressure nozzle 23 for secondary driving, so that the cloth can continue to move along the gas, reducing the probability that the gas is insufficient to drive the cloth to move as the distance between the cloth and the high-pressure nozzle 23 increases, and improving the conveying effect of the cloth.

[0068] With reference to Figure 2 And Figure 5 , the arranging mechanism 7 is arranged on the machine body 1, and the dyed cloth is neatly stacked on the inner bottom of the machine body 1 through the arranging mechanism 7. The arranging mechanism 7 comprises an arranging frame 71, two arranging rods 72 and a rotating assembly 73. The arranging frame 71 is rotatably installed on the machine body 1. The two arranging rods 72 are respectively rotatably installed at the bottom end of the arranging frame 71 and are in a horizontal state. The cloth is moved from the fixing tube 21 to between the two arranging rods 72. The two arranging rods 72 are both arranging rods 72 made of plastic material, and the surface of the arranging rod 72 is smooth.

[0071] The working principle of the embodiment of the application is as follows:

[0072] After the cloth enters into the machine body 1, the cloth passes through the overflow pipe 12 under the action of the cloth lifting wheel 13, the overflow dye in the overflow pipe 12 dyes the cloth, the dyed cloth enters into the fixing pipe 21, the high-pressure gas pipe 22 starts to spray high-pressure gas to the cloth in the fixing pipe 21, so that the dye on the cloth can further penetrate into the inside of the cloth, thereby improving the dyeing effect, and at the same time, the gas blown by the high-pressure nozzle 23 flows in the fixing pipe 21, when the gas flows along the outside wall of the flow guide cover 32 from the side of the heating pipe 31, the air pressure difference between the inside and outside of the heating pipe 31 makes the hot gas in the inside of the heating pipe 31 flow out from the heating pipe 31, thereby heating the subsequent conveying space of the dyed cloth, so that the cloth can always keep uniform temperature in the inside of the machine body 1, thereby ensuring the dyeing effect of the cloth.
