The present invention will be further described in conjunction with the accompanying drawings and specific embodiments, which are to be understood by those skilled in the art. The dryer for elastic and extensible textiles of the present invention comprises a baking drum, and the drying cylinder comprises a cylinder body 1 arranged horizontally, and the central portion of the cylinder body 1 is outwardly curved to make the cylinder body as a whole. It is drum-shaped and has a heating source inside the barrel 1. A temperature sensor 7 is provided on the outside of the barrel 1, and a temperature sensor 7 is connected to the control computer 12. The temperature sensor 7 is preferably an infrared temperature sensor, so that the temperature of the surface of the barrel 1 can be measured without coming into contact with the barrel 1, and the operation of the barrel 1 is not affected. In the embodiment shown in FIG. 1, the heating source comprises a heat-conducting medium 6 disposed in a lower portion of the inner cavity of the barrel 1. The heat-conducting medium 6 is provided with a heater 5, and the heater 5 is connected to the heating controller 4 to conduct heat. The medium 6 may be a heat transfer oil having a boiling point of 180 degrees Celsius or more, and the heater 5 may be a resistance wire heater or the like. The heating controller 4 is also connected to the control computer 12. There may be a plurality of temperature sensors 7, which transmit the measured average temperature of the surface of the barrel before and after the contact of the barrel 1 to the textile, the average temperature of the surface of the textile, and the like to the control computer 12, and the control computer 12 issues a control command based on the temperature information. To the heating controller 4, the heating power is adjusted by the heating controller 4 to maintain the surface temperature of the barrel 1 at the required temperature.

The rotating shaft 2 is connected to the center of the two ends of the barrel body 1. The rotating shaft 2 is mounted on the bracket through the bearing 3. The rotating shaft of one end is connected to the motor 10 through the transmission device 9, and the motor 10 is connected with the frequency converter 11, the frequency converter 11 and The control computer 12 is connected. A cloth speed detector 8 is also provided on one side of the barrel 1, and the cloth speed detector 8 is connected to the control computer 12. The cloth speed detector 8 detects the current traveling speed of the textile, and transmits the measured speed value to the control computer 12, and the control computer 12 issues a control command to the frequency converter 11 according to the current traveling speed of the textile, and the frequency converter 11 The rotational speed of the motor 10 is controlled to maintain the desired travel speed of the textile. Since the length of the textile and the temperature required for drying change during the drying process, it can be seen from the above embodiments that the present invention can adjust the drying temperature, the running speed and the like in real time to adapt to the change and achieve optimal drying. process. As shown in FIG. 2, the heating source may also be steam disposed in the inner cavity of the barrel, and the barrel body 1 is provided at one end. The steam inlet pipe 13 has a condensed water outlet pipe 15 at the other end, and the steam inlet pipe 13 and the condensate water outlet pipe 15 respectively pass through the center of the rotary shaft 2, and the condensed water outlet pipe 15 extends to the bottom of the inner cavity of the cylinder body 1. In this embodiment, the heating source is water vapor, and the water vapor enters the inner cavity of the barrel 1 from the steam inlet pipe 13, and the barrel 1 is heated. The water vapor is condensed into condensed water 14 after being exothermic, collected at the bottom of the inner cavity of the barrel 1, and discharged by the condensed water outlet pipe 15. The steam input pipe 13 and the condensed water output pipe 15 are respectively disposed at the center of the rotating shaft 2, so that the steam input pipe 13 and the condensed water output pipe 15 can be fixed, stable and reliable. In the same dryer, the barrel shape, running speed, and surface temperature of each of the drying cylinders are different. Wherein, the arc curvature of the drying cylinder is sequentially decreased from front to back until the curvature is 0, that is, the final baking cylinder is a straight cylinder. During the drying process, the stretchability of the edge of the textile tends to be greater than that of the middle portion. Therefore, the present invention designs the baking drum into a drum shape, forcing the middle portion of the textile to be stretched more, so that the middle portion of the textile is adapted to the extension of the edge to ensure The textile is flat. And as the textile gradually dries, its stretch rate will become smaller and smaller. In the present invention, the arc curvature of the bake tube is sequentially reduced from front to back, and the change can be accommodated. Different textiles have different stretch ratios, and the textiles can be selected from the dryers having the optimum curvature to accommodate the textiles as needed. Information such as the variety, thickness, and moisture content of the textile can be output to the control computer for automatic control.

The textile is wound around the roller in turn, and the spiral on the roller pushes the textile laterally to prevent curling. Further, a plurality of air nozzles may be provided behind the anti-hemming device, and high-speed, high-pressure compressed gas may be sprayed toward the folded cloth edge to blow the cloth edge back to a smooth state.

Finally, a cotton knitted fabric having a basis weight of 230 g/m 2 will be described as an example. The cotton knitted fabric was first subjected to extrusion dehumidification, and the water content after the treatment was 28.6% by mass. The dryer consists of 40 drying cylinders. The ratio of the height of the curved surface to the length of the barrel is from 40% to 0%, every 0.5%. The wet cloth width of the cotton knitted fabric was 2.35 ratio, the width after drying was 2.06 meters, and the width change rate was 14%; the length of the wet cloth was 56.0 meters, the length after drying was 60.8 meters, and the length change rate was 8.6%. Therefore, the cotton knitted fabric is selected to be entered by a drying cylinder having a ratio of the height of the curved surface to the length of the barrel of 14%, and dried by 28 drying cylinders. The cotton knit cloth after the final drying is neat and tidy, and the effect is good.
