Abstract

The invention relates to the field of a compound coating machine, aiming at providing a roll gap regulating system. The system uses an air cylinder as one of power sources for controlling a transferring roll to move in a linear guide rail, a linear stepping motor is used as another power source for controlling the transferring roll moving in the linear guide rail and applies thrust to the transferring roll through a screw rod and a micro-space sliding block, and the two power sources act together to ensure the reliable controlled sliding of the transferring roll on the linear guide rail. A control system controls the linear stepping motor and the air cylinder to control the movement of the transferring roll according to a gap set value, a gap detection device detects a gap value in real time and feeds the value back to the control system so as to ensure the accuracy of automatic regulation. In view of the accuracy requirement of the roll gap, the linear stepping motor converts a rotational motion into a linear motion through the screw rod, and the component on the linear guide rail direction of the sliding displacement of the micro-space sliding block on the wedge-shaped surface of a mounting base is the moving displacement of the transferring roll relative to a metering roll, so that the high-accuracy micro-gap movement is achieved.

Description

technical field [0001] The invention relates to the field of coating compound machines, in particular to a roller gap adjustment system and a control process. Background technique [0002] At present, the compounding method widely used in China is mostly coating first and then compounding, and the coating is more commonly used as roller-rotating coating, that is, there is a gap between the metering roller and the transfer roller, and the coating liquid is injected above the gap, and the transfer The rollers rotate, transporting the coating fluid away. The gap value between the rollers here is extremely important, which directly affects the thickness of the coating, and the general gap value is 7 to 12 wires. The existing adjustment gap is measured by a feeler gauge and adjusted by a manual handwheel. The adjustment of this method is extremely difficult, and the individual differences are relatively large; and the adjustable distance range between the gaps is small, which i...
