Dyeing machine

Abstract

A dyeing machine includes a machine base defining a cylindrical receiving chamber and a cloth passage for the circulation of a fed piece of cloth, and a jet nozzle upwardly mounted in one end of the cloth passage and adapted for ejecting a liquid coloring matter to dye the fed piece of cloth and to move the fed piece of cloth through the cloth passage.

Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a dyeing machine and, more particularly, to a simple structure of dyeing machine, which reduces friction resistance to the fed piece of cloth, preventing damage to the structure of the fed piece of cloth during dyeing operation.

[0002] A conventional dyeing machine is known comprising a machine base defining a cylindrical receiving chamber and a cloth passage, a jet nozzle disposed in a horizontal position, an overflow nozzle disposed in a vertical position above the elevation of the jet nozzle, a first cloth guide roller disposed in front of the jet nozzle and adapted for guiding a piece of cloth from the cloth passage over the jet nozzle into the cylindrical receiving chamber for dyeing, a second cloth guide roller suspended above the overflow nozzle and adapted for guiding a piece of cloth from the cloth passage over the overflow nozzle into the cylindrical receiving chamber for dyeing. This design of dyeing machine enables the fed piece of cloth to be circulated through the receiving chamber rapidly, and prevents the fed piece of cloth from being wrinkled. However, the arrangement of the jet nozzle, the overflow nozzle, and the guide rollers is complicated. When the piece of cloth moved over the cloth guide rollers, a friction resistance is produced to the moving piece of cloth, and the cloth guide rollers may damage the structure of the fed piece of cloth.

SUMMARY OF THE INVENTION

[0003] The present invention has been accomplished to provide a dyeing machine, which eliminates the aforesaid problem. It is one object of the present invention to provide a dyeing machine, which eliminates the use of cloth guide rollers. It is another object of the present invention to provide a dyeing machine, which uses the upward ejecting force of the liquid coloring matter ejected from the jet nozzle to move the fed piece of cloth. According to one aspect of the present invention, the dyeing machine comprises a machine base defining a cylindrical receiving chamber and a cloth passage for the circulation of a fed piece of cloth, and a jet nozzle upwardly mounted in one end of the cloth passage and adapted for ejecting a liquid coloring matter to dye the fed piece of cloth and to move the fed piece of cloth through the cloth passage. According to another aspect of the present invention, the cloth passage has a front end terminating in a smoothly arched front bent, which holds the jet nozzle for smooth circulation of the fed piece of cloth. Because the dyeing machine does not use any cloth guide rollers, all the drawbacks seen in the aforesaid prior art dyeing machine due to the use of cloth guide rollers are eliminated.

BRIEF DESCRIPTION OF THE DRAWING

[0004] FIG. 1 is a plain view of a dyeing machine constructed according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0005] Referring to the annexed drawing of FIG. 1, a dyeing machine is shown comprising a machine base 1 defining a cylindrical receiving chamber 11 and a cloth passage 12. The cloth passage 12 has a front input end terminating in a smoothly arched front bent, and a rear output end connected to one end of the receiving chamber 11. A jet nozzle 13 is coupled to the front bent of the cloth passage 12 and arranged in an upwardly extended position. The input end of the jet nozzle 13 faces downwards and aimed at the other end of the receiving chamber 11. Thus, the jet nozzle 13, the cloth passage 12, and the receiving chamber 11 form a continuous cloth circulation path.

[0006] When a piece of cloth 2 fed into the machine base 1 of the dyeing machine, it is circulated through the receiving chamber 11 and the cloth passage 12. When the fed piece of cloth 2 passes from the receiving chamber 11 into the cloth passage 12 through the jet nozzle 13, a liquid coloring matter is ejected upwards from the jet nozzle 13 toward the moving piece of cloth 2 to dye the moving piece of cloth 2 and simultaneously to force the moving piece of cloth 2 into the cloth passage 12. Because the invention eliminates the use of cloth guide rollers to guide movement of the fed piece of cloth, all the drawbacks produced due to the installation of cloth guide rollers in the dyeing machine are eliminated.

[0007] A prototype of dyeing machine has been constructed with the features of FIG. 1. The dyeing machine functions smoothly to provide all of the features discussed earlier.

[0008] Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.

Claims

1. A dyeing machine comprising a machine base defining a cylindrical receiving chamber and a cloth passage for the circulation of a fed piece of cloth, and a jet nozzle adapted for ejecting a liquid coloring matter to dye the fed piece of cloth, wherein said cloth passage has a front input end terminating in a smoothly arched front bent, a rear output end connected to an opposite end of said receiving chamber; said jet nozzle is coupled to the front bent of said cloth passage and arranged in an upwardly extended position, having an input end downwardly facing an opposite end of said receiving chamber.
