Abstract

In a dyeing machine which does not have any cloth feeding rollers, cloth is ejected by nozzle 60 to hit the V-shaped top of small chamber 32, which is said to loosen the cloth, and is immersed in small tube 31 in dye whose level is adjusted by the pivoting of perforated baffle 35 in large chamber 34. The cloth then passes to be stacked in large tube 36 where perforated panel 37 forms dye reservoir 38. The cloth then passes, for recirculation, through cranked tube part 41 into chamber 39 where curved filtering net 40 forms dye chamber 308. Reservoir 38 is connected by pipe to chamber 308. Pump 70 returns dye from chambers 34 and 308 to the nozzle.

Description

TITLE: A DYEING MACHINE WITHOUT ROLLERS This invention relates to an improved dyeing machine without rollers.

FIG. 5 illustrates a first prior art dyeing machine.

As shown, the dyeing liquid will flow downwardly and accumulated in a large tubular passage 11, the cloth 13 will be transmitted by a roller 12 into a nozzle 14 which will spray dyeing liquid to color the cloth 13, and the cloth 13 will then be transmitted into a small tubular passage 15.

FIG. 6 shows a second prior art dyeing machine. As the first prior art dyeing machine, the dyeing liquid will flow downwardly and accumulated in a large tubular passage 21, the cloth 23 will be transmitted by a roller 22 into a nozzle 24, and the cloth 23 will then be transmitted into a small tubular passage 25.

However, the speed of the rollers 12 and 22 of the dyeing machines shown in FIGS. 5 and 6 cannot adapt to the travelling speed of the cloth thereby making the cloth twist together and therefore damaging the surface of the cloth.

Therefore, it is an object of the present invention to provide a dyeing machine without rollers which may obviate and mitigate the above-mentioned drawbacks.

This invention relates to an improved dyeing machine without rollers.

It is the primary object of the present invention to provide a dyeing machine without rollers which can reduce the required amount of dyeing liquid in operation.

It is another object of the present invention to provide a dyeing machine without rollers which can evenly and rapidly dye the cloth.

It is still another object of the present invention to provide a dyeing machine without rollers which can preventing the cloth from twisting together.

It is still another object of the present invention to provide a dyeing machine without rollers which utilizes cyclic dyeing liquid to move the cloth.

It is a further object of the present invention to provide a dyeing machine without rollers which can make the cloth naturally stack up in the large tubular passage.

Other objects of the invention will in part be obvious. and in part hereinafter pointed out.

The invention accordingly consists of features of constructions and method, combination of elements, arrangement of parts and steps of the method which will be exemplified in the constructions and method hereinafter disclosed, the scope of the application of which will be indicated in the claims following.

FIG. 1 is a working view of the present invention; FIG. 2 is an enlarged fragmentary view of FIG. 1; FIG. 3 illustrates the interior structure of the large tubular passage; FIG. 4 is a sectional view of the large tubular passage; FIG. 5 illustrates a first prior art dyeing machine; and FIG. 6 illustrates a second prior art dyeing machine.

For the purpose of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawings. Specific language will be used to describe same. It will, nevertheless, be understood that no limitation of the scope of the invention is thereby intended, such alternations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated herein being contemplated as would normally occur to one skilled in the art to which the invention relates.

With reference to the drawings and in particular to FIG. 1 thereof, the dyeing machine without cyclic rollers according to the present invention mainly comprises a circular trough 39, a large tubular passage 36, and a small tubular passage 31.

The circular trough 39 is provided with a nozzle 60 at the upper portion and a neck portion 41 below the nozzle 60. A curved filtering net 402 is disposed on lower portion of the circular trough 39 thereby forming a chamber 308 which is connected to a pump 70 via a pipe 315.

The small tubular passage 31 is located at a lower level than the neck portion 41 of the circular trough 39 and has a small circular portion 32 at an end and a large circular porton 34 at another end. The small circular portion 32 is provided with a V-shaped top 32, while the large circular portion 34 has an adjustable baffle 35 therein. The top of the large circular portion 34 is higher than that of the small tubular passage 31. As shown in FIG. 2, the baffle 35 is pivotally mounted within the large circular porton 34 and is higher than the bottom but lower than the top of the small tubular passage 31.

The baffle 35 is formed with a plurality of perforations 305. The bottom of the large circular portion 34 of the tubular passage 31 is connected with a pump 70 via a pipe 316.

The large tubular passage 36 is located under the small tubular passage 31 and connected with the outlet 325 of the large circular portion 34 of the small tubular passage 36 at an end. The other end of the large tubular passage 36 is connected with the neck portion 41. A perforated panel 37 having a plurality of holes 307 is mounted at the lower portion of the large tubular passage 36 thus forming a reservoir 38.

The pump 70 is connected to a heat exchanger 80 which is in turn connected to the nozzle 60 through a pipe 318.

When in use, the small tubular passage 31 is first filled with dyeing liquid. Then, as the dyeing liquid 30 is ejected out of the nozzle 60, the cloth 50 will be pushed by the dyeing liquid 30 to hit on the V-shaped top 33 of the small circular portion 32 of the small tubular passage 31 thereby loosening the cloth50. Since the cloth 50 is not conveyed by rollers, it is no longer necessary to take friction into consideration and so the cloth will not be damaged any longer. The sectorial baffle 35 is used for, keeping dyeing liquid 30 in the small tubular passage 31 and can be turned to adjust the level of the dyeing liquid 50 in the small tubular passage 31. Hence, the cloth 50 will be first sprayed with the dyeing liquid 30 by the nozzle 60 and then immersed into the dyeing liquid 30 in the small tubular passage 31.As there is a distance between the small tubular passage 31 and the large tubular passage 36, there will be a large space for the cloth 50 thereby preventing the cloth 50 from twisting together. In addition, the cloth 50 will be naturally stacked up in the large tubular passage 36 in order. In the meantime, the excessive dyeing liquid 30 flows down to the pump 70 via a pipe 316 from the bottom of the large circular portion 34 of the small tubular passage 31. Some of the dyeing liquid 30 flows downwardly through the holes 307 of the perforated panel 37 into the reservoir 38, which in turn flows to the chamber 308 of the circular trough 39. Thereafter, the dyeing liquid 308 will be forced to flow through a heat exchanger 35 to the nozzle 60 by the pump 70 thus circulating the dyeing liquid in the dyeing machine.

The invention is naturally not limited in any sense to the particular features specified in the forgoing or to the details of the particular embodiment which has been chosen in order to illustrate the invention.

Consideration can be given to all kinds of variants of the particular embodiment which has been described by way of example and of its constituent elements without thereby departing from the scope of the invention. This invention accordingly includes all the means constituting technical equivalents of the means described as well as their combinations.
