Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chemical solution removing device for removing a chemical solution from a sliver after being immersed in a chemical solution, in a shrink-proofing machine for coating a polymer material such as a resin on the surface of fibers such as wool to perform a shrink-proofing process.

[0002]

[Prior Art]

 The shrinkproofing machine is equipped with a plurality of chemical tanks such as a chlorination tank, a dechlorination tank, and a resin coating tank, and the sliver is immersed in the chemical liquids in these chemical tanks in order for continuous processing. Inside the chemical tank, there is a roller for immersing the sliver in which a large number of through holes connecting the inside and the outside are formed in the peripheral wall of the hollow main body, and the sliver keeps the outer circumference of the sliver immersing roller constant. The drug solution penetrates between the fibers of the sliver while moving over time.

In this type of device, a pair of upper and lower squeezing rollers for removing the chemical liquid are provided on the downstream side of each chemical liquid tank in order to prevent the chemical liquid in the previous tank from mixing into the next liquid tank. The chemical contained in the sliver is squeezed out by passing the sliver after immersion between the squeezing rollers. All of the squeezed chemical solution was returned to the chemical solution tank by a pan provided below the squeezing roller with the chemical solution tank side inclined downward.

[0004]

[Problems to be solved by the device]

 However, since the reconstituted chemical liquid contains a large amount of impurities such as sliver residual fat and dirt, there was a problem that the contamination in the chemical liquid tank becomes severe when used for a long time. In addition, some of the impurities undergo a neutralization reaction with the chemical liquid to form salts, and the salts precipitate at the bottom of the tank.If the precipitated salts become clogged in the through holes of the sliver dipping roller, the chemical liquid sliver The permeation into the product deteriorated and the finish was adversely affected.

[0005]

In view of the above circumstances, the present invention has been made to prevent the inside of the chemical liquid tank from being contaminated by the returned chemical liquid, and has the following structure to solve the problem. That is, the chemical solution removing device according to the present invention is a chemical solution removing device that removes the chemical solution from the sliver after being immersed in the chemical solution in the shrink-proofing process, and the chemical solution contained in the sliver is contained by pressing the sliver passing through. A pair of squeezing rollers for squeezing the sliver, and a pan for receiving the chemical liquid falling from the sliver and guiding it into the chemical liquid tank are provided, and a drain port for discharging the chemical liquid flowing down on the pan is formed at an appropriate position of the pan. A feature is that a removable drain plug is provided at the drain port.

[0006]

[Action]

 If a drain plug is provided at the drain port, all the chemical solution squeezed by the squeezing roller will be returned to the chemical solution tank along the receiving tray. If the drain plug is removed from the drain port, a part of the drug solution squeezed by the squeezing roller is discharged to the outside from the drain port. By attaching and detaching the drain plug in consideration of the degree of contamination of the returned chemicals and the relationship with replenishment of chemicals, it is possible to prevent contamination in the chemical tank and save chemicals.

【Example】

 1 and 2 are a front view and a plan view of an embodiment of a shrink-proofing machine according to the present invention. The shrink-proofing machine 1 includes a plurality of chemical liquid tanks 2, ... such as a chlorination tank, a dechlorination tank, a resin coating tank, and a cleaning tank, and a chemical liquid removing device 3 provided on the downstream side of each chemical liquid tank. , And a dryer 4 are provided. The sliver 6, supplied from the creel 5 is transferred in a certain direction, and the chemicals in the chemical tanks 2, ... Is configured to. The processed sliver 6, ... Is stored in a coil by the coiler 7 ,. Since the sliver is stretched and thinned during transfer, two slivers are stored as one set to adjust the thickness.

The chemical liquid tanks 2, ... Have the same configuration except for the chlorination tank 2 (1), and these chemical liquid tanks 2, ... Are configured as shown in FIG. That is, the chemical liquid tank 2 has a rectangular parallelepiped shape with an open upper portion, and the chemical liquid 10 having a predetermined concentration is stored inside the chemical liquid tank 2 at a constant level. The sliver dipping roller 12 is provided in the central portion of the tank in a state of being submerged in the chemical liquid 10, and guide rollers 13 to 16 are provided before and after the sliver dipping roller and above the edge of the tank. As shown in the drawing, the sliver 6 is wound around each of the rollers 12 to 16, and the sliver dipping roller 12 is rotated in the direction of the arrow to move the sliver 6 in a fixed direction. The sliver 6 moves in the drug solution 10 over a certain period of time, during which it penetrates between the fibers of the drug solution. Reference numerals 17 and 18 in the figure denote heaters for heating and retaining heat of the chemical liquid.

The main body of the sliver dipping roller 12 is formed in a hollow shape, and a large number of through holes 19, ... Connecting the inside and the outside are formed in the peripheral wall of the main body. By sucking the chemical liquid in the sliver dipping roller 12 with a pump, the external chemical liquid flows into the roller through the through holes 19, ... At this time, since the chemical liquid flows between the fibers of the sliver 6, the sliver 6 is well filled with the chemical liquid. It penetrates.

The chemical liquid removing device 3 has a pair of upper and lower squeezing rollers 25 and 26, which are provided facing each other and rotate in opposite directions, between the guide rollers 15 and 16. By pinching the sliver with the pair of squeezing rollers 25 and 26, the chemical liquid contained in the sliver is squeezed out. Below the squeezing rollers 25 and 26, there is provided a receiving tray 27 which is inclined so that the side of the chemical liquid tank 2 is in a lower position. As shown in FIG. 4, drainage ports 28, 28 are provided on both left and right sides of the tray 27, and drainage plugs 29 are detachably attached to the drainage ports. If a drain plug 29 is attached to the drain port 28, the drug solution squeezed out from the sliver 6 is returned to the drug solution tank 2 through the receiving tray 27. Further, if the drain plug 29 is removed, a part of the chemical liquid squeezed out from the sliver 6 is recovered as the drain liquid from the drain port 28.

The number and position of the drainage ports 28 may be set arbitrarily in consideration of the amount of drainage collected. Further, the central portion of the tray 27 may be raised so that the chemical liquid dropped from the squeezing roller 26 is guided to the drainage ports 28, 28.

[Effect of the device]

 As described above, the chemical liquid removing device according to the present invention can arbitrarily collect the chemical liquid of the sliver squeezed by the squeezing roller as drainage liquid, so that the contamination in the chemical liquid tank can be prevented and the chemical liquid can be prevented. The chemical solution in the tank can be adjusted easily.
