Glass fiber wall cloth edge-cutting electronic error-correcting apparatus

Abstract

The invention discloses an electronic deviation rectifying device used in glass fiber wallhanging cut trimming, consisting of a control system and an execution system. The control system comprises at least two color mark sensors, a programmable controller, a transducer, and a revolving coder; the execution system is composed of an execution motor frame, a slide bar frame, a sensor frame, a cuttersaddle, an execution motor, a screw mandrel and a cutter. After any of the color mark sensors detects color streak which serves as a color mark inlaid along the edge on the upper surface at one side of the edge to be cut of the wallhanging, the color mark sensor sends the location information to the programmable controller to control the movement of the cutter, so as to rectify deviation. The signals of the color mark sensors can be used in high speed deviation rectification and low speed deviation rectification. The revolving coder feeds back the detected speed of the threads of the wallhanging to the programmable controller to control the movement speed of the cutter, so as to ensure the constant ratio of deviation rectification to the speed of the threads of the wallhanging. The electronic deviation rectifying device realizes automated control to deviation rectification and is high in rectification precision, stable in performance, simple in operation and installation and low in making cost.

Description

technical field [0001] The invention relates to a device for correcting deviation when trimming glass fiber wall cloth. Background technique [0002] Fiberglass wall cloth is a new type of wall decoration material made of glass fiber cloth as the base material, coated with resin and printed on the surface. It is widely used in the field of architectural decoration because of its many advantages such as various patterns, bright colors, no fading and aging when used indoors, good fire resistance and moisture resistance, and can be scrubbed. Weaving glass fiber to get glass fiber gray cloth, coloring the glass fiber gray cloth to get colored gray cloth, printing the colored gray cloth to get glass fiber wall cloth semi-finished product, and then trimming and rolling the glass fiber wall cloth semi-finished product Get the finished glass fiber wall covering. The fiberglass wall covering cutting machine for trimming the semi-finished glass fiber wall covering (abbreviated as wa...

Problems solved by technology

However, the deviation correction function of this mechanism is not strong, the deviation correction is not accurate enough, and it is not suitable for the trimming and deviation correction of glass fiber wall cloth with high precision requirements, and if the deviation is relatively large, if the deviation is still corrected at the same speed, it will not be achieved. The results of deviation correction, coupled with the fact that the glass fiber wall cloth is smooth and the friction coefficient is small, the linear speed of the cloth will change during the transmission process. If the deviation correction speed cannot maintain a certain ratio with the real-time linear speed of the wall cloth, the deviation correction effect will not be good. would be ideal
