Description

  The present invention relates to “softening and swelling machines for woven and knitted fabrics”. This eliminates the tension generated during the manufacture of woven and knitted fabrics, softens, gives volume by expansion, and mechanical flexibility used in the process of adjusting width / length and weight (grams) And expansion machine.

  Currently used softening and expansion machines provide movement to the fabric by the effect of air in the air tunnel. The dough is struck against a specially shaped surface or grid by the pressing force of air. Its purpose is to give the fabric flexibility and volume. In another machine construction used for the same purpose, the dough is rolled inside the drum and struck against the fins inside the drum for softening. In both of these aspects, the process is assisted by blowing hot air and steam over the dough.

  In the machine according to the present invention, the fabric that has undergone the dyeing, washing, and wrinkle-stretching steps is further processed by a pre-drying step that is added to the system as necessary, and is ideal for the softening and expansion processes. Alternatively, the dried dough is brought to ideal humidity by passing through a steam unit that is added to the system for the softening and expansion processes as required. The work material sewn on the guide cloth inside the machine is passed through a spiral expander located inside the entrance side of the mechanical beating unit and accumulated in the J box in the cabin. At that time, the width of the dough is expanded and the winding of the edge (or roll) is expanded. Thereafter, the dough is pulled up in the vertical direction at the desired travel speed by a speed-adjustable pull cylinder located in the first beating line. On the other hand, all beaters or selected beaters can be adjusted to the intended specific rotation speed and direction and are positioned on both sides of the fabric with the horizontal axes offset from each other. The beater applies a mechanical and continuous impact to the dough from both sides of the dough or from one desired side. The upper surface of these drums can be used as a helical wound to enhance the expansion function. Thus, the fabric is softened and expanded, and the weight (grams) is adjusted by bringing the width and length dimensions closer to the desired values. Next, the dough received from the first pull cylinder passes through the second pull cylinder that operates synchronously, and moves downward in the vertical direction using gravity. On the other hand, the dough is again subjected to a similar beating process. During these processes, they are prepared by heating by air, steam, boiling oil (temperature and amount required in the process), or by direct gas release in the circulating air preparation unit. It is fed from the special blow channel and nozzle into the cabin by a circulation fan with regulated flow rate, again at the flow rate required by the process. Spent air drawn from the cabin is cleaned by a special filter. This air is temperature-controlled and circulates in the cabin. The dough drawn out from the J box at the exit of the cabin reaches the dust removal unit by the roll being stretched again using the expander cylinder. Residues, debris clips and dust on both sides of the dough are sucked through a high vacuum dust removal channel located in this unit and collected in a filter in a dust collection chamber. The fabric accumulated in the J-box on the inlet side of the natural cooling / folding mechanism from the outlet of the dust removal unit is pulled up in the vertical direction with the help of a pull cylinder. And transported to the cart with the help of a folding mechanism.

  In a machine that operates on the principle of imparting motion to the fabric by the effect of air inside the air tunnel, the fabric is transported by air, which is expensive. There is also a very high risk of damaging the fabric. Machines that perform the expansion and softening process by striking the dough against the fins in the drum while rolling the dough inside the drum make the process more difficult, and the dough cannot be processed continuously, so the production capacity Decreases. In the present invention, since the cloth to be processed is conveyed into the machine by the pull cylinder, power consumption can be minimized. Since the dough is spread in the beating process, damage can be prevented. Because the dough contacts the circulating air in a continuously expanded state, the duration of the drying process is shorter than the equivalent machine.

FIG. 1 is a detailed view of a softening and expanding machine according to the present invention. FIG. 2 is a top view.

  The humidity-adjusted workpiece dough (1) is supplied to the cabin inlet side J box (5) in the mechanical beating and softening cabin (4), which is adjusted to the desired air characteristics by the air conditioning unit (19). . This supply is performed by being pulled by the inlet side pull cylinder (2), and its width and length are expanded by the inlet side expander cylinder (3). The workpiece dough (1) in the cabin entrance J box passes through the elliptical beating-expander drum (7) while being pulled by the cabin's first pull cylinder (8), which is adjustable in speed. On the other hand, a desired number of elliptical beating-expander drums (7) may be active depending on the type of fabric to be processed and the characteristics to be imparted. An elliptical beating-expander drum with adjustable rotation speed and rotation direction can perform the beating and expansion process on both sides or one of the desired sides of the workpiece (1). While the work dough (1) passing through the second pull cylinder of the cabin, which is equivalent to the first pull cylinder (8) of the cabin, moves vertically downward, the dough is an elliptical beating-expander drum (the desired number , Direction and speed) and reach the exit J box (20) of the cabin via the guide cylinder (6). As the work dough (1) is pulled by the dust removal unit pull cylinder (11) to pass through the dust removal unit (14), the width of the dough and the fringing of the edges thereof are expanded by the expander cylinder (10) of the dust removal system. Expanded. While the workpiece dough (1) passes through the interior of the dust removal unit (14), undesired foreign matter (for example, debris clips and dust) is sucked up by the dust removal channel (15) around it. It is done. These collected foreign matters are filtered in the dust removal filter chamber (18). After a certain amount of the processed fabric (1) that has passed through the dust removal unit (14) is collected in the J box of the natural cooling unit (21) disposed in the natural cooling unit (16), this fabric is It is pulled by the pull cylinder of the cooling unit (12) and cooled by coming into contact with the outside air. Thereafter, the processed fabric (17) drawn from the natural cooling unit (16) by the pull cylinder of the natural cooling unit (12) is taken out and folded by the fabric vibration device (13).

The present invention can be used for all fabrics and knitted fabrics that need to be softened and expanded in a textile manufacturing facility.
