Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dyeing machine.

[0002]

[Prior art]

 When dyeing a cloth with a dyeing machine, the optimal speed of the dyeing liquid jetted from the nozzle toward the cloth depends on the thickness and type of the cloth. That is, it is advantageous to spray the dyeing liquid at a high speed on a cloth using a thick cloth or a long fiber, since the dyeing is completed in a short time. However, when high pressure is applied to a thin cloth or a cloth using short fibers, the tissue is deformed and the cloth is damaged, so the dyeing solution must be jetted at a low speed.

Therefore, as shown in FIG. 3, a cloth guide tube a and a dyeing tank b extending in a substantially horizontal direction are provided, and one end of the cloth guide tube a is connected to one end of the dyeing tank b. Nozzle c (commonly known as overflow nozzle) that jets the dyeing liquid at a low speed and pressure nozzle (commonly known as jet nozzle) d that jets the dyeing liquid at a high speed at different positions near the other end of the nozzle. Is installed, and a cloth feed roller e is installed between the cloth guide tube a and the other end of the dyeing tank b to form a cloth circulation path with the cloth guide tube a and the dyeing tank b. A dyeing machine is known which is capable of coping with various kinds of cloths by passing through appropriate nozzles.

However, in this dyeing machine, a single cloth feed roller e is used for sending the cloth to either the overflow nozzle c or the jet nozzle d. When passing through the fabric, the fabric circulation path becomes unnecessarily long, and as a result, the circulation speed of the fabric becomes slow, so that dyeing takes time and efficiency is low. At this time, in the case of a thick cloth, a large tension is applied by its own weight, so that wrinkles are likely to cause uneven dyeing.

[0005]

[Problems to be solved by the invention]

 An object of the present invention is to provide a dyeing machine that can efficiently dye a cloth to be dyed according to its thickness and type, and that does not cause creases or wrinkles on the cloth to be dyed. .

[0006]

[Means for Solving the Problems]

 The dyeing machine of the present invention is provided with a cloth guide tube and a dye tank in the machine body, connects one end of the cloth guide tube to one end of the dye tank, and opens forward near the other end of the cloth guide tube. A first inlet and a second inlet that opens upward at a position higher than the first inlet are formed, and the dyeing solution is jetted at a high speed toward the inside of the cloth guide tube at the first inlet. And an overflow nozzle for dropping the dyeing solution toward the inside of the cloth guide tube is provided at the second inlet, and is provided in front of the first inlet and above the second inlet. , First and second cloth feed rollers for feeding the cloth to be dyed from the other end of the dyeing vessel toward the other end of the cloth feed tube are provided, and the diameter of the second cloth feed roller is adjusted. Compared to the diameter of the first cloth feed roller Te configured as the same diameter or larger diameter.

In the case where the cloth to be dyed is a knitted cloth or a cloth using short fibers, the cloth is fed from the second inlet to the cloth guide tube by the second cloth feed roller, and passes through the second inlet. The dyeing liquid supplied from the overflow nozzle is sprayed on the cloth to be dyed.

At this time, the first cloth feed roller functions as an auxiliary roller. In the case where the cloth to be dyed is a relatively thick woven cloth or a cloth using long fibers, the first cloth feed roller located below the second cloth feed roller allows the first cloth to be passed through the shorter path in a short time. From the entrance to the cloth guide tube to prevent heavy loads from being applied to heavy cloth. Further, when passing through the first inlet, the dyeing solution is jetted from the jet nozzle onto the cloth to be dyed at high speed.

The cloth to be dyed falls into the dyeing tank from the outlet of the cloth guide tube, is discharged from the other end of the dyeing tank, and circulates through the cloth guide tube and the dyeing tank until the dyeing operation is completed. The configuration in which the second cloth feed roller has the same diameter as or larger than the first cloth feed roller can be used even if the cloth to be dyed is hung at a high position. Prevents the tension per unit area applied to the fabric to be dyed from excessively increasing at the contact point with the fabric.

[0010]

[Embodiment of the invention]

 As shown in FIG. 1 and FIG. 2, the dyeing machine of the present invention applies a pressure to a hollow body 1 having a circular cross section, a dyeing tank 11 and a cloth guide tube 12 installed in the body 1, and a dyeing solution. A jet nozzle 13 for jetting at high speed, an overflow nozzle 14 for dropping the dyeing solution without applying pressure, and a first cloth feed roller 15 disposed in front of the jet nozzle 13. A second cloth feed roller 16 disposed above the overflow nozzle 14.

The dyeing tank 11 is formed by bending a cylindrical body thicker than the cloth guide tube 12 into a substantially U-shape along the lower half of the body 1, and the dyeing liquid is stored at the bottom thereof. ing. One end of the dyeing tank 11 is connected to one end of a cloth guide tube 12 extending substantially horizontally, and the other end of the cloth guide tube 12 is arranged near the other end of the dyeing tank 11. The tank 11 forms a cloth circulation path through which the cloth to be dyed 2 circulates.

A first entrance opening forward and a second entrance opening upward at a higher position are formed near the other end of the cloth guide tube 12, respectively. A jet nozzle 13 is provided, and an overflow nozzle 14 is provided at the second inlet. The jet nozzle 13 and the overflow nozzle 14 are respectively connected to a dyeing liquid supply path drawn from the outside of the body 1, and the jet nozzle 13 transfers the supplied dyeing liquid to the inside of the cloth guide tube 12. , And the overflow nozzle 14 causes the dyeing liquid to drop vertically toward the inside of the cloth guide tube 12.

The first cloth feed roller 15 is rotatably disposed directly above the other end of the dyeing tank 11 and is driven to rotate by an electric motor (not shown). Then, the first cloth feed roller 15 passes the cloth to be dyed 2 discharged from the other end of the dyeing tank 11 through a jet nozzle 13 as shown in FIG. It is sent to the first entrance. The second cloth feed roller 16 has the same diameter as or larger than the first cloth feed roller 15, and is rotatably provided above the first roller 15. Similarly to the first cloth feed roller 15, the second cloth feed roller 16 is also driven to rotate by a motor (not shown). The second cloth feed roller 16 transfers the cloth to be dyed 2 discharged from the other end of the dyeing tank 11 through an overflow nozzle 14 to a second inlet of the cloth guide tube 12 as shown in FIG. To be sent to.

If the cloth to be dyed 2 is a cloth using a relatively thick woven cloth or long fiber, the cloth is hardly damaged even when a high-speed dyeing liquid is sprayed. It is fed into the cloth guide tube 12 through the inlet. Since the path from the first cloth feed roller 15 to the first inlet is shorter than the path passing through the second cloth feed roller 16, the cloth circulation path can be circulated in a short time. Further, since the first cloth feed roller 15 is installed at a low position, a large tension is not applied even to a thick cloth that is heavy containing the dyeing liquid.

If the cloth to be dyed 2 is a knitted knitted cloth or a cloth using staple fibers, the cloth is easily damaged by jetting a high-speed dyeing liquid, so the cloth guide is passed through the second cloth feed roller 16 through the second inlet. Feed into tube 12. At this time, the first cloth feed roller 15 functions as an auxiliary roller for supporting the cloth to be dyed on the way. Although the second cloth feed roller 16 is installed at a higher position than the first cloth feed roller 15, the cloth to be dyed 2 is often relatively light and the diameter of the second cloth feed roller 16 is reduced. Since the diameter of the first cloth feed roller 15 is the same as or larger than that of the first cloth feed roller 15, excessive tension is not applied to the cloth 2 to be dyed at the contact portion with the second cloth feed roller 16.

The dye solution discharged from the jet nozzle 3 and the overflow nozzle 14 falls from the cloth guide tube 12 to the dye tank 11 and passes through the cloth guide tube 12 and the dye tank 11 to be dyed. The cloth 2 is dyed. Until the dyeing operation is completed, the cloth to be dyed 2 circulates in the cloth circulation path constituted by the cloth guide tube 12 and the dyeing tank 11. Note that the shapes and the like of the machine body 1 and the dyeing tank 11 are not limited to the illustrated forms, and any mechanism can be adopted as a drive mechanism of the first cloth feed roller 15 and the second cloth feed roller 16.

[0017]

[Effect of the invention]

 According to the dyeing machine of the present invention, when the cloth to be dyed passes through the jet nozzle installed below, it does not needlessly pass through a long path, so that dyeing can be efficiently performed in a short time, and at this time, Since the first cloth feed roller for supporting the cloth to be dyed is installed at a low position, even if the cloth to be dyed is heavy, excessive tension is applied and creases and wrinkles do not occur. In addition, the second cloth feed roller arranged at a higher position has the same diameter as or larger than the first cloth feed roller, so that the cloth to be dyed is formed at the contact portion with the second cloth feed roller. Prevents the applied tension per unit area from becoming too large and causing creases and wrinkles.
