Definitions

• the present invention relates to a machine for dyeing fabrics, as well as an installation for dyeing fabrics comprising this machine.
• the purpose of the fabric dyeing machine according to the invention is to remedy these drawbacks while retaining the advantages of other machines, in particular those with an ultra-short bath ratio, with the savings in time, heat, etc.
• the fabric dyeing machine according to the invention is characterized by an apron serving as a support for the fabric during its transfer from the bottom of the tank to the top of said tank.
• the fabric dyeing machine according to the invention is characterized by an apron serving the fabric as it enters by passing over the drive turnstile towards the chute, where the fabric is entrained by the dye, to then be taken up by said support apron at the bottom of the tank and transferred to the drive turnstile.
• the operation becomes continuous until the completion of dyeing.
• FIG. 2 is a schematic vertical sectional view of a machine for dyeing overflow fabrics according to the invention.
• - Fig. 3 gives a partial section of the support apron of a machine for dyeing fabrics, according to the invention.
• the installation for dyeing the fabrics illustrated in FIG. 1 comprises, in addition to the machine 1 proper, a tank 2 for preparing the liquid. dyeing with its respective steam 2 and water 4 inlets, its drain 5 and injection 6 valves.
• the solution is brought into the liquid circuit by a pipe 7 and a bypass valve 8.
• a pump 9 actuated by a motor 10 circulates the liquid, the flow rate of which is regulated by the valve 11, and which enters the machine 1 by a distributor 12 at the inlet of a chute 13.
• the liquid enters the chute 13 by overflow and drives the fabric coming from a turnstile 23 towards the other upper end of the machine 1 before filling a tank 14 dye to the desired level.
• the liquid leaves the tank 14 through a filter 15 before being heated in a heat exchanger 16, provided with valves 17 for inlet and outlet of water and steam. It is then taken up by pump 9 which simultaneously ensures good temperature homogeneity throughout the liquid before being reintroduced into the machine 1.
• the machine 1 for dyeing fabrics according to the invention illustrated in FIG. 2 comprises as essential elements the tank 14, a drive turnstile 23 on which is mounted a support deck 20, a chute 13 for the flow of the liquid distributed by the double distributor 12, of an automatic folding machine 21 of adjustable stroke fabrics and controlled by a mechanical speed variator, an adjustable fastening system 22 consisting of a set of three rollers mounted on a rack, of a roller 25 which with the drive turnstile 23 constitutes a set of toothed wheels and pinions connected by a chain 31 on which are fixed supports 32 forming the support deck 20, with slats 33.
• the machine 1 according to the invention is also equipped with a hood 30 for protection against vapor emanations from the dye bath, which is located above the drive turnstile 23 and is provided with a door 29 for loading and tissue unloading 18.
• an inspection door 26 is provided, situated at the rear of the machine, which serves to control the flow of the fabric and the cleaning of the bath.
• the machine also includes an automatic shutdown system 27, a drain chute 28, overflow and drain valves (35), and other auxiliary devices such as a thermometer, level, etc.
• an automatic shutdown system 27 a drain chute 28, overflow and drain valves (35), and other auxiliary devices such as a thermometer, level, etc.
• a strap is provided inside the machine along the path that the fabric will take in the machine.
• the fabric 18 is unwound from an unloading turnstile 19 and fixed to one end of said strap which hangs from the drive turnstile 23, while the other end of the strap hangs from the edge of the tank 14 to the right of the door 29 for loading the hood 30.
• the drive turnstile 23 is set in motion, driven by a gearmotor not shown whose speed is adjustable by means of a frequency converter allows both a fabric unwinding speed of the order of 40 to 400 m / minute.
• the turnstile 23 rotates at reduced speed and drives the tissue towards the chute 13, where the treatment liquid is circulated and drives the tissue to the other end of the chute 13, where it is put in folds by the automatic folder 21, the folds falling and accumulating at the bottom of the tank in the treatment liquid until the entire piece of fabric to be treated has entered the machine.
• the strap by pulling on the strap through the free end outside of the hood 30, it is possible to wind the fabric and sew the two ends of the piece of fabric to start the continuous treatment.
• the transfer of the tissue soaked in liquid from the bottom of the tank 14 to the drive chute 13 is done without significant traction efforts thanks to the support apron 20 which, mounted on a chain, mounts the fabric of the roller 25 in the bottom of the tank 14 up to the turnstile 23.
• the tying system is included or not in the unwinding of the fabric.
• the seam connecting the two ends of the fabric is undone, the strap is attached to the end of the piece while the other end of the piece is fixed to the turnstile 19, which this time is used to unload the machine 1, which can then be drained by means of the drain valve 35.
• The. support apron as shown in FIG. 3, consists of a set of polypropylene slats (33) fixed to chains by means of angles 32.
• the chains are mounted on the toothed wheels respectively of the drive turnstile upper to the inlet of the machine and the lower roller which is in the bath.
• the setting in motion of the axis of the drive turnstile ensures the setting of the whole of the support apron which ensures the continuous movement of the fabric in the machine 1.
