Description

TECHNICAL FIELD

[0001] The application relates to a cheese dyeing technology field, in particular to a cheese negative pressure dyeing equipment and method. BACKGROUND

[0002] The cheese has a wide application in the textile industry, and the cheese produced is white, and usually needs to be dyed before being applied to production. The cheese dyeing method is to put the cheese into a dyeing cabin, wash and bleach the cheese, add dyeing liquid after the cheese is washed clean, and use a circulating pump to flush and dye the cheese to improve the permeability of the dye and the yarn, so as to realize full dyeing. Because a large number of bubbles are adsorbed on the surface of the cheese and the yarn fiber during the dyeing process, the dye and the cheese fiber are not fully combined, resulting in uneven dyeing and the phenomenon of pitting.

[0003] In particular, in order to reduce pollution to the environment, an ultrahigh pressure salt-free dyeing process is adopted. During the ultrahigh pressure fixing process, the bubbles in the yarn fiber will burst under the action of ultrahigh pressure, affecting the combination of the dye and the yarn fiber, so that the yarn dyeing pitting is more obvious. Therefore, a dyeing equipment is needed to extract the small bubbles existing between the dye and the yarn fiber by using negative pressure during the dyeing process, to ensure that the dyed yarn is evenly dyed, reduce pitting, and improve the dyeing quality.

[0069] In the process of water adding to the dyeing cabin 1, the electromagnetic heater 332 heats the water inlet pipe 33 to increase the temperature, so that the dyeing substance molecules move faster and the dyeing speed is accelerated. In the process of water circulation, the electromagnetic heater 332 continues to heat the dyeing solution to maintain the temperature of the dyeing solution constant. When the dyeing is finished, the dyeing solution needs to be discharged. At this time, the condenser 333 is opened, the water circulation mode is started, and the temperature of the dyeing solution is reduced through the condenser 333. When the temperature of the dyeing solution is reduced to the safe range, the dyeing solution is discharged, which can effectively prevent the high-temperature dyeing solution from damaging the surrounding environment, and a large amount of water is not needed to absorb the temperature of the discharged dyeing solution, so that the water is reduced, the cooling speed is accelerated, and the production efficiency is improved.

[0076] When the bobbin is dyed from the outside to the inside, the dyeing solution can be input from the first water guide channel 431 to the lower side of the frame base 41.

[0077] Reference Figure 9 、 Figure 10 A water guide hole 411 is arranged on the frame base 41, the water guide hole 411 cooperates with the water inlet 11 arranged at the edge of the dyeing cabin 1 to input water from the outside of the bobbin, a water blocking ring 412 is arranged at the center position of the frame base 41, the water blocking ring 412 covers the water inlet 11 at the center position of the dyeing cabin 1, a water guide channel 413 is arranged around the water blocking ring 412, a water guide ring seat 414 is fixed on the water guide channel 413, a bottom support plate 415 for supporting the bobbin is fixed on the water guide ring seat 414, the support rod 42 is inserted into the water guide ring seat 414, and a second water guide channel 416 is reserved between the support rod 42 and the water guide ring seat 414; the second water guide channel 416 corresponds to the first water guide channel 431.

[0078] When water enters from the inlet 11 located at the edge of the dyeing chamber 1, the dyeing solution enters the dyeing chamber 1 through the water guide hole 411.

During the process of opening the sealing cover 5, the sealing cover 5 is rotated by the hollow rotating platform reducer 74, so that the limiting grooves 151 and the limiting protrusions 51 are aligned. At this time, the lifting cylinder 73 retracts, so that the sealing cover 5 is separated from the U-shaped limiting ring 15. Then the traction cylinder 75 retracts, controlling the sealing cover 5 to flip, thereby opening the upper end of the dyeing chamber 1.

[0087] If the dyeing cabin 1 is high pressure, the gas can be quickly discharged from the pressure balance pipe 521, so that the pressure in the dyeing cabin 1 is balanced with the outside air pressure.
