Abstract
Pneumohydraulic liquid dye-spraying apparatus including a rectangular
straight nozzle (13) and an upper and a lower sector-shaped air input
conduits (25). The nozzle (13) is composed of upper and lower sets of
guide boards (1311,1321) having opposite oblique guide edges each
defining an elongated straight spray jet (131,132). Each spray jet
(131,132) is independently provided with an air input conduit (25). One
end of the conduit (25) is formed as an inlet (251) which is diverged
and extended toward the other end of the conduit to form a sector-shaped
outlet (252) for connecting with the nozzle (13). An atomizing nozzle
(253,254) is mounted on the conduit (25). During spraying operation, the
liquid dye passing through the nozzle (13) is evenly atomized and
sprayed onto a dyed piece (3). The amount of upper and lower sprayed air
and the liquid dye can be independently controlled to meet requirements
of different dyed pieces.
Description
- The present invention is related to an improved pneumohydraulic liquid dye-spraying apparatus.
- A conventional pneumohydraulic liquid dye-spraying apparatus includes a cycle unit and a nozzle disposed in the cycle unit. The cycle unit is composed of a machine head, a cloth-guiding tube and a cloth reservoir connected with each other. A piece of cloth to be dyed is placed in the cycle unit. The nozzle injects high pressure liquid dye onto the cloth to dye the cloth. Simultaneously, the injection force will drive the cloth to move in the cycle unit through the cloth-guiding tube and cloth reservoir back to the nozzle for next spraying and dying. Taiwanese Patent No. 325063 published in January, 1998 discloses such an apparatus.
- However, the above apparatus has many shortcomings needing to be overcome. Taiwanese Patent No. 337795 published in July, 1998 discloses a pneumohydraulic dying machine. Such dying machine includes improved cloth-guiding tube and cloth reservoir and a nozzle which can selectively spray liquid dye in forward or backward direction. This structure overcomes the problems of tangling and knotting of the cloth.
- However, in the above conventional pneumohydraulic dying machine, the nozzle is not only used to spray the liquid dye, but also is necessary to inject liquid dye at high pressure sufficient to drive and circulate the cloth. Therefore, the pump must have great power and a great amount of liquid dye is necessary to achieve this object.
- In Taiwanese Patent Application No. 88207289, the applicant discloses a pneumohydraulic dying machine in which atomized liquid dye is mixed with air to spray onto the cloth and drive the cloth. The cloth is driven by injected air so that the pump needn't have great power and only a little amount of liquid dye is necessary.
- However, the liquid dye-spraying apparatus of the above pneumohydraulic dying machine cannot adjust the amount of the sprayed liquid dye and air in accordance with the variety and thickness of the cloth. Therefore, the dying condition can be hardly freely controlled and dying material is wasted.
- It is therefore a primary object of the present invention to provide an improved pneumohydraulic liquid dye-spraying apparatus in which the air pipeline is divided into an upper and a lower bypasses respectively connected to the upper and lower air input conduits. The air input conduits are respectively connected to the upper and lower sides of the nozzle which are respectively connected with upper and lower liquid dye bypasses. The respective bypasses are independently provided with switches for independently controlling the flow amount of the respective bypasses and amount of the liquid dye so as to meet requirements of different dyed pieces.
- The present invention can be best understood through the following description and accompanying drawings wherein:
-
- Fig. 1 is a plane view of the pneumohydraulic liquid dye-spraying apparatus of the present invention;
- Fig. 2 is a perspective exploded view of the pneumohydraulic liquid dye-spraying apparatus of the present invention; and
- Fig. 3 is a perspective exploded view of the rectangular straight nozzle of the pneumohydraulic liquid dye-spraying apparatus of the present invention.
-
- Please refer to Fig. 1. The pneumohydraulic liquid dye-spraying apparatus of the present invention includes a
cylindrical body 10 and a pneumohydraulic liquid dye-spraying unit 20. A dyed piece 3 ( such as a piece of cloth ) is driven and circulated in thecylindrical body 10. During circulation, the cloth passes through acloth guiding tube 11 and is guided by a cloth-carryingroller 12. Between thecloth guiding tube 11 and is guided by a cloth-carryingroller 12, thedyed piece 3 passes through the pneumohydraulic liquid dye-spraying unit 20. - The pneumohydraulic liquid dye-
spraying unit 20 is composed of a rectangularstraight nozzle 13 and twoair input conduits 25 arranged on upper and lower side of thenozzle 13. An air circulation pipeline 24 is laid in front of thenozzle 13, including an upper and a lower air bypasses 241, 242 which are respectively connected to the upper andlower conduits 25. The upper andlower conduits 25 are respectively connected to the upper and lower sides of thenozzle 13. One end of eachconduit 25 is provided with aninlet 251 for connecting with the upper and lower air bypasses 241, 242. The other end is diverged into a sector-shaped outlet 252 for connecting with the upper and lower sides of thenozzle 13. Cooperatively, thenozzle 13 is provided with elongatedstraight spray jets nozzle 13 is composed of quite simplified upper and lower sets ofguide boards guide boards straight spray jets fixing boards 133. Theconduits 25 are further formed with atomizingnozzles - According to the above arrangement, during spraying operation of the pneumohydraulic liquid dye-spraying apparatus of the present invention, through the upper and lower air bypasses 241, 242 and the
conduits 25, a great amount of air is strongly blown into thenozzle 13, whereby thedyed piece 3 is driven and circulated by the injected air. At this time, via the upper and lower liquid dye bypasses 226, 227, the liquid dye is atomized and input into theconduits 25 to be mixed with the great amount of air. Then the liquid dye through thenozzle 13 is sprayed onto the dyed piece for dying the same. The air and the liquid dye are input from upper and lower sides into thenozzle 13 by independent bypasses and conduits so that the air and the liquid dye can be more evenly mixed at a unified ratio and the evenness of the dye can be more easily controlled. - In addition, in order to adjust the amount of the input air and liquid dye in accordance with different properties and thickness of the dyed piece, the air bypasses 241, 242 and the liquid dye bypasses 226, 227 are respectively independently provided with
switch valves cloth 3 can be controlled to an optimal condition. Moreover, during adjustment, by means of bias control, the soft dyed piece can be conveyed and sprayed in an extended state so as to avoid straight folding track.
