Description

{A dyeing machine of tubular for high pressure}

The present invention relates to a dyeing machine for dyeing fabrics not only cotton fabrics but also fabrics made of resins such as polyesters.

In particular, it consists of an air supply pipe for blowing air into the circular fabric, an air sensing bar for adjusting the swelling size of the circular fabric, and a pressure regulating valve for automatically adjusting the pressure in the dyeing tank. It is a high-pressure tubular dyeing machine for dyeing resin materials.

In general, the fabric has a plate-shaped fabric woven in one form due to the combination of weft and warp, and is divided into a circular fabric woven in the form of two sheets overlapped in a cylindrical shape.

By the way, the woven fabric of the two types of fabric is given a variety of colors through the process of dyeing, dyeing is divided into high-pressure type and atmospheric pressure according to the material of the woven fabric.

The high pressure type and the normal pressure type are classified into a high pressure type dyeing machine in which a pressure is applied in a dyeing tank for dyeing, and a dyeing machine which is dyed under an atmospheric pressure without applying pressure is called a normal pressure type dyeing machine.

The higher the dyeing, the better the dyeing is generally, but in particular, when dyeing a woven fabric made of resin such as polyester, it is necessary to raise the high temperature.

However, cotton fabrics avoid dyeing at high temperatures, so they are dyed at relatively low temperatures in tanks that maintain normal atmospheric pressure.

In addition, such a dyeing machine can be manufactured at a relatively low production cost since there is no need to seal the tank.

On the contrary, the high pressure dyeing machine is a machine for dyeing fabrics woven with resins such as polyester, which is difficult to dye, and is dyed while maintaining high temperature and high pressure by sealing the inside of the tank.

By the way, in the conventional various dyeing machines, the fabric wrinkled through the process of dyeing has been completed as a single fabric through the process of ironing, wrinkled fabric that can not be unfolded even by the process of ironing during the dyeing process It is unusual to be.

This is often the case of a high-pressure dyeing machine dyeing under high temperature and high pressure, and occurs in the fabric of the span system to maintain the elasticity by putting rubber yarn, etc. in the fabric of resins rather than cotton.

Therefore, in order to solve this problem, in the process of spraying the dye solution of the dyeing machine shakes overlap, the tubular dyeing machine is commonly used to blow out the air by blowing the air inside the circular fabric often.

However, in the case of a tubular dyeing machine for dyeing such a circular fabric, there is a problem that cannot be applied to a high-temperature high-pressure dyeing machine because air must be blown into a double-ply fabric.

That is, the process of blowing air into the circular fabric in a closed dye tank of high temperature and high pressure requires a large force.

In addition, as air is blown in, the pressure is increased so that more pressure is needed, and there is always a risk.

Therefore, the conventional dyeing machine application form is, firstly, a normal pressure dyeing machine is used in the case of cotton fabrics, and a form adding a tubular type is used since it is a normal pressure type.

Second, in the case of woven fabrics such as polyester, a high-pressure dyeing machine is used. Due to the characteristics of the high-pressure type, it was impossible to adopt a tubular.

Therefore, the trend of dyeing while taking a lot of defect rate.

Of course, there have been no solutions for solving this problem, but among them, recently registered patent application No. 20-230450, name; Examine the fabric dyeing machine and pick up the problem.

In the case of this registered technology, the claim 1 claims the atmospheric type tubular dyeing machine, and the claim 2 claims the high pressure type dyeing machine, but the structural claim is not possible in the form of a tubular dyeing machine. Doing.

That is, due to the characteristics of the high-pressure type, it is not possible to use the tubular dyeing method of blowing air into the circular fabric, and to insert the separation rod 35 'of FIG. (Shown in Figure 5).

This is a crude technical configuration that does not have the effect of the tubular dyeing method to avoid wrinkles of the fabric is insignificant.

The present invention is composed of an air supply pipe for blowing air into the inside of the circular fabric and the air sensing bar for adjusting the swelling size of the circular fabric, a pressure control valve for automatically adjusting the pressure in the dyeing tank, such as polyester difficult to dye It is a high-pressure tubular dyeing machine for dyeing resin materials.

In addition, it is a high-pressure tubular dyeing machine that has a configuration that uses the shape of the nozzle and the air sensing tube of the air supply pipe for the large circular fabric and the configuration for the narrow circular fabric to be used separately.

The configuration of the present invention has been schematically described above, and the configuration of the present invention and its operation will be described in detail with the drawings shown.

First, the high-pressure tubular dyeing machine of the present invention is capable of dyeing all kinds of fabrics, but in particular, it is a dyeing machine having a great advantage in dyeing the fabric of the span system including fabric and synthetic rubber materials such as polyester.

Figure 1 is a block diagram for explaining a method of operation of the high-pressure tubular dyeing machine of the present invention, a circular woven fabric (P) woven in a single layer is introduced to move the body wound on the roller.

This roller is fastened to the top of the salt tank 11 shown, the first roller 20 has a large diameter and the diameter of the second and third rollers (21, 22) to the diameter of the first roll (20) Compared to the small form.

The circular fabric moving in the form of a support zigzag wrapping the outer circumferential surface of the roller moves in the direction of the arrow shown.

At the lower end and the left side of the first roller 20, an interlocking rod 25 is formed to rotate the circular fabric which is pushed down to the left and right and move in a folding form.

This is to prevent the phenomenon of twisting the circular fabric during dyeing, consideration to prevent the wrinkles on the fabric after dyeing.

In this way, the fabrics contained in the salt solution in the salt tank 11 in a stacked shape are drawn dyeing, and is pulled up by the rotational force of the third roller 22 shown.

Air injection pipe 30 is responsible for the configuration of blowing air to the two-ply circular fabric to be pulled up, as shown in the high temperature at a high pressure in the air injection pipe 30 is in contact with the outer circumferential surface of the rising circular fabric When the air is injected, the two-ply circular fabrics are inflated as shown in FIGS.

However, when the air is blown in due to the characteristics of the high-temperature high-pressure dyeing machine, the pressure in the dyeing tank 10 is continuously increased, and an air injection of a larger pressure must be made.

However, since such continuous high pressure air spraying is impossible and there is a possibility that the temperature rises excessively and the circular fabric which requires dyeing may be injured and the explosion may remain, the present invention provides a means for regulating this pressure. .

This means is the most important feature in the present invention is the air detection bar (41, 42) and the pressure control valve 35 shown in detail in Figs.

That is, the air sensing bars 41 and 42 detect the measured pressure in consideration of the pressure of the swelling circular fabric, and operate the pressure regulating valve 35 through the control means.

Therefore, to remove the pressure in the dyeing tank (10) to maintain the pressure and to put the air back through the air injection pipe 30 to remove the wrinkles generated in the circular fabric.

In addition, the dyeing machine of the present invention can be effectively dyed both a narrow circular fabric and a wide circular fabric, it is shown in Figures 3 and 4.

That is, in the case of a wide fabric as shown in FIG. 3, the center of the roller and the air injection pipe 30 is moved and dyed with a center.

Therefore, the timing of valve opening and closing is controlled by the pressure sensing of the air sensing bars 41 and 42 which can be interlocked with the center of the air spray pipe.

At this time, the air detection bar (41, 42) formed on the left and right of the air injection pipe 30 is fixed to the tank wall surface as shown in Figure 1 and maintained in the stopped state, as shown in Figure 4 When dyeing the circular fabric (2) of the start operation.

In addition, the dyeing machine of the present invention is provided with a plurality of salt spray pipe (39), and serves to spray the salt solution to the moving circular fabric as shown in FIG.

The present invention is a useful tubular dyeing machine that dyes fabrics such as polyester, which are difficult to dye, but minimizes the formation of wrinkles.

In addition, it is an advanced type of dyeing machine to fundamentally block the formation of wrinkles even when dyeing the fabric of the span system containing rubber yarn.
