Automatic fabric tension control system suitable for knitting open-width wet processing unit

Abstract

The invention relates to an automatic fabric tension control system suitable for a knitting open-width wet processing unit. The system comprises at least more than two groups of wet processing units, wherein adjacent wet processing units are in station connection to form the open-width wet processing unit; drum/roller group stations and roller groups which are matched with the drum/roller groups are arranged in box bodies of the wet processing units; and the system is characterized in that: the drum/roller groups are main driving components; and the roller groups comprise driving rollers and driven rollers which are matched with each other. The invention has outstanding characteristics that: the drums/rollers, rollers and traction rollers in each wet processing unit are main driving components; numerical values of various driving mechanisms can be directly set according to differences of fabric composition and technical requirements of fabrics machined by the unit, so that the fabrics do not have tension, the fabrics are prevented from being subjected to tensile deformation in each wet processing unit, and the quality of the fabrics is guaranteed.

Description

technical field [0001] The invention relates to a tension control system suitable for a knitting open-width wet processing unit, in particular to an automatic fabric tension control system suitable for a knitting open-width wet processing unit. Background technique [0002] At present, in the open-width wet processing units such as open-width washing and open-width desizing in the printing and dyeing industry, the drums and cloth guide rollers in each open-width wet processing unit (washing tank) are passive, and only the rollers are active. That is, a unit has only one main drive. The synchronization between the front and rear units is controlled by a tension frame. When the transmission speed of the rear unit slows down, the fabric that shuttles on the drum and cloth guide roller will loosen. The angle sensor on the axle head of the tension frame, the angle sensor just sends a signal to the transmission of the rear unit to accelerate the speed. On the contrary, when the...

Problems solved by technology

However, due to its structural characteristics, knitted fabrics are easy to stretch, especially for knitted warp and weft knitted fabrics containing elastic fibers, which can easily cause stretching and deformation of the fabric, and even produce defective products.

Therefore, the current wet treatment process in my country's knitting printing and dyeing industry generally adopts a rope-like intermittent process method, but the rope-shaped intermittent process method consumes a lot of water, electricity, steam, and auxiliaries, and the sewage discharge is large. The production efficiency is low, and it is easy to produce quality problems such as wrinkles, rubbing, and fluffing
