BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot air cloth drying apparatus for continuously drying cloth after printing, dyeing, washing with water and the like.

[0002]

2. Description of the Related Art Conventionally, a hot drier such as a cylinder drier or a roller drier or a net-conveying drier is mainly used for continuously drying a fabric after the steps such as printing, dyeing and washing with water. It is used.

[0003]

However, in hot-flue dryers such as cylinder dryers and roller dryers, tension is applied to the fabric during drying, so the fabric is stretched in the length direction, and the product comes out of the dryer. Becomes flat and the texture becomes bad. Therefore, when these dryers are used, in the subsequent process, they are over-fed by a tentering tenter to spread them in the width direction to improve flatness and texture, but rayon and knit products are No improvement is seen and these dryers cannot be used.

On the other hand, in a net-conveying type dryer, belt conveyors stretched with mesh-shaped endless belts are arranged above and below, and the cloth is conveyed along a conveying path formed by the upper and lower belt conveyors, and at the same time, the endless belt is conveyed. The air ducts are arranged in a zigzag pattern across the conveyor path across the belt, hot air is jetted from the slit nozzles of the upper and lower air ducts to the cloth conveyed on the conveyor path, and the cloth is undulated by the jet pressure of the hot air. I try to dry it while putting it on.

These devices are intended to enhance the shrinking effect and the relaxing effect and give the texture to the cloth by drying the cloth while rubbing and loosening the cloth by air beating by blowing hot air. Because hot air is constantly blowing out with a certain strength,
The fabric moves meandering in the vertical direction.

However, such a meandering movement merely means that the vertical movement of the fabric is sequentially transmitted along with the running of the fabric, and any region of the fabric is not subjected to intense beating in the vertical direction, and The rubbing effect was not enough.

Therefore, an object of the present invention is to provide a hot-air cloth drying device capable of imparting vigorous hot air beating to the cloth in the vertical direction and enhancing the kneading effect of the cloth.

[0008]

In the hot air fabric drying apparatus of the present invention, a fabric transporting conveyor having a mesh-shaped endless belt stretched is arranged vertically so as to form a fabric transporting path in the middle. , Above and below the transport path over the endless belt, a number of air ducts are arranged in parallel in the front-back direction of the transport path at a predetermined interval, each air duct,
An inlet for the hot air sent from the air blowing means is provided on one side, and a slit nozzle for injecting the hot air entered from this inlet to the cloth through the endless belt is approximately the same width as the entire width of the cloth on the surface on the transport path side. The fabric is continuously provided by the hot air jetted and supplied from this slit nozzle, and is made into a wavy shape in the conveying path, and the fabric is dried while being conveyed and supplied from one side to the other side by the cloth conveying conveyor. The slit nozzles provided above and below the transport path are arranged in a staggered manner, and shutters are provided in front of the slit nozzles of each of the air ducts to blow air above and below the transport path. Connecting swinging means consisting of a link mechanism for swinging the duct groups alternately to the air duct groups above and below the transport path,
The slit nozzles are opened and closed by alternately swinging the upper and lower blower duct groups by the swinging means.

[0009]

According to the hot-air cloth drying apparatus of the present invention, the cloth fed into the conveying path is dried by the hot air ejected from the slit nozzle until it exits the conveying path, and at the same time, the hot air is jetted from above and below. As a result, the cloth is conveyed while being wavy.

Moreover, since the slit nozzles are opened and closed by swinging the air duct groups above and below the transport path, hot air can be jetted pulsatingly onto the cloth.
