Transmission system and method for synchronous control of textile machinery

Abstract

The invention discloses a textile machinery synchronous control transmission system which comprises an unwinding mechanism, a first tension adjusting mechanism, an overfeeding mechanism, a setting machine, a second tension adjusting mechanism, a flattening mechanism, a winding mechanism and a controller. The unwinding mechanism, the first tension adjusting mechanism, the overfeeding mechanism, the setting machine, the second tension adjusting mechanism, the flattening mechanism and the winding mechanism are sequentially arranged in the cloth conveying direction. The overfeeding mechanism comprises a first overfeeding frame and a second overfeeding frame, a first overfeeding roller pair is installed on the first overfeeding frame, a second overfeeding roller pair is installed on the second overfeeding frame, and the two overfeeding roller pairs jointly carry out overfeeding conveying on wide cloth; the two pairs of overfeeding rollers are arranged and used for overfeeding conveying, the overfeeding rollers capable of being controlled by the controller and the controller can prevent cloth from being obliquely pulled, the overfeeding mechanism is matched with the adjusting mechanism so that automatic deviation correction of the cloth and automatic adjustment of the tension of the cloth can be achieved, constant-tension operation is kept, and the shaping effect is improved.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to a transmission system and method for synchronous control of textile machinery. Background technique [0002] The process of cloth shaping is that the cloth passes through the shaping machine, and is dried and shaped under the action of high-temperature hot air of the shaping machine. After shaping, the cloth has a good hand feeling and stable size. By controlling parameters such as heating temperature, cloth conveying speed and overfeeding amount in the setting machine, the quality control of the cloth can be realized. Overfeeding is to adjust the feeding speed of the overfeeding roller to overcome the unstable state such as elongation and narrowing of the width of the cloth caused by external force. Shrinkage is reduced. Reverse overfeeding makes warp yarn elongate, weft density decrease, gram weight decrease, warp shrinkage becomes larger, and fabric wid...

Problems solved by technology

[0003] In the existing technology center, the overfeeding mechanism overfeeds the cloth into the setting machine. Since the width of the cloth is getting wider and wider, the manufacturing accuracy of the entire overfeeding roller suitable for the width of the cloth is extremely high. The size of the overfeeding roller itself or A slight deviation during installation will cause the fabric to be pulled diagonally, which not only increases the production cost, but also affects the quality of the fabric setting; the transmission mechanisms on both sides of the fabric setting machine are poorly synchronized, resulting in stretching or even tearing of the fabric surface; It cannot be straightened in time when pulling, resulting in a high defective rate; in the process of fabric shaping, the constant tension of fabric is an important factor to ensure the quality of fabric shaping. In the compensation and correction of the overfeeding process of the mechanism, the fabric tension is prone to large fluctuations, and after the fluctuations, the adjustment time of the fabric tension is longer, and the defective rate increases
