Variable transmission paper feed mechanism for die-cutting machine

Abstract

The invention relates to a variable transmission paper feed mechanism for a die-cutting machine. The paper feed mechanism comprises a cam-planetary gear epicyclic train component, a speed-increasing gearbox, a synchronous belt, a paper feeding roller and a paper feeding belt roller, wherein the cam-planetary gear epicyclic train component is connected with the speed-increasing gearbox, and the speed-increasing gearbox is connected with the paper feeding roller and the paper feeding belt roller through the synchronous belt. Compared with the prior art, the paper feed mechanism is stable and reliable in movement and high in paper feeding accuracy, large-stroke high-speed smooth paper feeding can be realized, manufacturing cost can be controlled, and later maintenance and service costs are low.

technical field [0001] The invention relates to a variable-speed transmission paper delivery mechanism of a die-cutting machine, in particular to a variable-speed transmission paper delivery mechanism of a die-cutting machine which adopts a cam-planetary gear epicyclic train. Background technique [0002] At present, there are two types of paper feeding mechanisms used in die-cutting machines: traditional mechanical variable speed transmission paper feeding mechanisms and servo control variable speed paper feeding mechanisms. The traditional mechanical transmission paper feeding mechanism includes: eccentric swing lever rotary speed transmission paper feeding mechanism, rotating guide rod variable speed transmission paper feeding mechanism, eccentric shaft gear variable speed transmission paper feeding mechanism, four-bar hinge-epicycle gear train variable speed transmission paper feeding mechanism and The oval gear variable speed transmission paper feeding mechanism, althou...

Problems solved by technology

The traditional mechanical transmission paper feeding mechanism includes: eccentric swing lever rotary speed transmission paper feeding mechanism, rotating guide rod variable speed transmission paper feeding mechanism, eccentric shaft gear variable speed transmission paper feeding mechanism, four-bar hinge-epicycle gear train variable speed transmission paper feeding mechanism and The oval gear variable speed transmission paper feeding mechanism, although the above-mentioned traditional mechanical variable speed transmission paper feeding mechanism can realize the variable speed transmission paper feeding of paper feeding, but the movement law of the paper feeding process is uncontrollable due to the limitation of the mechanism, especially for large strokes. High-speed paper feeding has high requirements on the movement law of the paper feeding process, so as to ensure the stability and accuracy of high-speed paper feeding. The traditional mechanical variable speed transmission paper feeding mechanism cannot realize the paper feeding process with large strokes and high-speed controllable motion laws. Therefore, a servo-controlled variable-speed paper feeding mechanism is produced, and an ideal paper feeding time-speed motion curve of the servo motor is set by the servo motor controller to realize a high-speed, stable, controllable and regular paper feeding process with a large stroke. Compared with the mechanical transmission mechanism, the servo control variable speed paper feeding mechanism has a high cost of the servo system, which requires professional debugging, and the maintenance and use costs in the later period are also high
