Energy-efficient transmission mechanism of transverse cutting machine

Abstract

The invention relates to an energy-efficient transmission mechanism of a transverse cutting machine. The energy-efficient transmission mechanism is characterized in that an upper knife roll and a lower knife roll are connected with a left gearbox rack and a right gearbox rack through inner bearing blocks and outer bearing blocks, upper knife roll gears are arranged at the two ends of the upper knife roll respectively, and lower knife roll gears are arranged at the two ends of the lower knife roll respectively. A driving motor is connected with an input gear shaft through two diaphragm couplings. The input gear shaft is sleeved with an eccentric bearing sleeve. An input gear of the input gear shaft is meshed with a big gear of a two-stage transmission gear set. A pinion of the two-stage transmission gear set is meshed with the corresponding lower knife roll gear. The lower knife roll gears are meshed with the corresponding upper knife roll gears. A self-aligning roller bearing is arranged in each inner bearing block, and a deep groove ball bearing is arranged in each outer bearing block. The energy-efficient transmission mechanism has the advantages of being large in reduction ratio and efficient and saving energy.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a high-efficiency and energy-saving transmission mechanism of a cross-cutting machine. Background technique [0002] The cross-cutting machine is the core equipment of the corrugated cardboard production line, which continuously cuts the corrugated cardboard according to a certain length. It directly affects the production speed of corrugated cardboard. In the prior art, the cross-cutting machine is driven by a single servo motor, and the servo motor is directly connected to the cutter roller, or transmits power to the cutter roller through a first-stage gear reduction mechanism. The servo motor is directly connected to the knife roller. When cutting high-gram weight corrugated cardboard at high speed, a servo motor with high torque and high power is required, and each revolution is a variable speed movement, which is easy to cause the whole machine to vibrate greatly; the first-stage...

AI Technical Summary

Problems solved by technology

The servo motor is directly connected to the knife roller. When cutting high-gram weight corrugated cardboard at high speed, a servo motor with high torque and high power is required, and each revolution is a variable speed movement, which is easy to cause the whole machine to vibrate greatly; the first-stage gear is used The deceleration mechanism transmits power to the knife roller. The deceleration ratio is generally around 1.8-2.1. The deceleration ratio is not large, and the cutting resistance is large. It needs a high-power servo motor to drive, and the power loss is too large.
