Description
The utility model relates to a kind of width checkout gear, especially for the width detector of the loose fabric in moving.
Fabric is in weaving process, though its width or a width of cloth of saying so be substantially have standard-sized, but fabric its width of cloth size fluctuation in last handling processes such as its rinsing, dyeing is bigger, because the density of fabric and the elastic difference of fiber, pulling force when mobile or the difference of tensity, its width random fluctuation, some loose fabrics such as gauze particularly, its width of cloth is influenced by the pulling force of roll shaft and comes and go, give the back processing of gauze, especially during reel, there is a limit irregular, causes the cutting blade size inhomogeneous, influence the quality of product processing.For addressing this problem, the someone proposes when coiling or unwinding, and moving with the way minimizing door amplitude wave of control rate or tension force, as the tenslator that CN2153563Y proposes, the method is not suitable for the detection and the control of cloth amplitude variationization on the gauze process line.
The purpose of this utility model is a kind of production line that is used to move of design, the device that can detect at any time and control the door width of cloth of loose fabric.
Design of the present utility model is, the cloth width of cloth detects controller, it comprises Photoelectric Detection light path, differential operational circuit, drive circuit and servomotor, it is characterized in that photoelectric detective circuit forms by some infrared emission tubes with its corresponding one by one infrared receiver tube; One oscillatory scanning circuit joins by in-gate circuit and photoelectric detective circuit input, and described oscillatory scanning circuit joins by out-gate circuit and photoelectric detective circuit output.
Described photoelectric detective circuit is a kind of infrared and receiving circuit of dynamic scan, and scanning circuit makes ultrared transmitting and receiving synchronously, transmit and receive from top to bottom or downwards and on, corresponding one by one.When adopting to shooting method, the cloth of different amplitudes by the time, the nothing emission optical signal that is blocked receives, what be not blocked has an emission optical signal.When adopting method for reflection, when the cloth of different amplitudes passed through, the emission optical signal that has that is blocked received, and the nothing emission optical signal that is not blocked receives, and inputs to differential operational amplifier, and the signal that is exaggerated is exported the servomotor work that promotes.The detection sensitivity height is not subject to environmental factor and disturbs, and working stability is reliable, is the advantage of this detection controller.This detector directly detects the variation of the cloth width of cloth in addition, and is more intuitive and reliable than indirect control tension variation.
