Honeycomb paper core high speed paper feeding and trimming device

Abstract

The invention discloses a honeycomb paper core high speed paper feeding and trimming device. The honeycomb paper core high speed paper feeding and trimming device comprises a work platform, a moving cutter and a fixing cutter which are arranged above the work platform and set in up and down horizontal tangent mode, a moving cutter driving mechanism used to drive the moving cutter to perform horizontal reciprocating movements so as to achieve paper cutting, a paper feeding roller and a paper pressing roller arranged in the horizontal direction above paper cutting stations of the moving cutter and the fixing cutter at an interval and used to convey honeycomb paper cores, a servo motor used to drive the paper feeding roller to rotate and a signal controller used to drive the servo motor to work, wherein a honeycomb paper core delivery passage for the honeycomb paper cores to pass is arranged between the paper feeding roller and the paper pressing roller, and the signal controller controls work efficiency of the servo motor according to work efficiency of the moving cutter driving mechanism. The honeycomb paper core high speed paper feeding and trimming device greatly improves paper feeding speed, further improves paper cutting speed of the moving cutter, can achieve 600-800 cutting times / min of high trimming speed, and greatly improves production efficiency of the honeycomb paper cores.

Description

technical field [0001] The invention relates to the field of honeycomb paper core production equipment, in particular to a honeycomb paper core high-speed paper feeding and cutting device. Background technique [0002] As we all know, cutting the honeycomb paper core is an essential process in the production process of the honeycomb paper core, and the design of the cutting device directly affects the production efficiency and production quality of the honeycomb paper core. Most of the devices use the cooperation between the moving knife and the fixed knife to complete the shearing action. The moving knife is fixed on the moving knife seat, and the moving knife seat is connected to the eccentric wheel set on the eccentric shaft. The eccentric shaft passes through the transmission assembly. Connect to the power output of the drive motor. [0003] For example, there is Chinese patent authorization announcement number CN100586671C to disclose a kind of honeycomb paper core aut...

AI Technical Summary

Problems solved by technology

[0005] However, there is a problem in the above two patents. The honeycomb paper core that needs to be cut is fed by sliding down from the paper guide plate by its own weight. The honeycomb paper core falls from the bottom surface of the fixed knife to the top surface of the workbench. The paper feeding speed is slow, which limits the cutting speed of the moving knife, and the cutting speed can only reach 350 knives / min, which greatly limits the production efficiency of the honeycomb paper core

In addition, because the honeycomb paper core is fed by its own weight, it cannot be effectively fixed during the cutting process, and it is easy to shift during the cutting process, which reduces the flatness of the cutting
