Paper shredding cutter processing equipment

Abstract

The invention discloses paper shredding cutter processing equipment and is used for fixing a plurality of cutter blades to the cutter shaft at certain intervals to form a paper shredding cutter. The processing equipment comprises a servo rotary mechanism and a pressurizing mechanism, wherein the servo rotary mechanism comprises a servomotor and a clamping device, and is used for clamping the end of the cutter shaft and driving the cutter shaft to rotate; and the pressurizing mechanism comprises a pressurizing drive unit and two pressurizing molds, the two pressurizing molds are positioned on the opposite sides of the cutter shaft, each pressurizing mold is provided with a plurality of pressurizing blocks, and the pressurizing blocks pressurize the cutter shaft after passing through the gap between the adjacent cutter blades. The paper shredding cutter pressurizes the cutter shaft by passing through the gap between the adjacent cutter blades in a stepwise rotary pressurizing mode, so that the material on the cutter shaft flows towards the inner bore of the cutter blades; and bulges are formed on both sides of each cutter blade to fix the cutter blade to the cutter shaft, thereby forming the paper shredding cutter. The paper shredding cutter processing equipment can process thin cutter blade paper shredding cutters, and the processed paper shredding cutters have strong overall structure.

Description

technical field [0001] The invention relates to a processing equipment for shredded paper knives, in particular to an equipment for processing shredded paper knives by using a forging method. Background technique [0002] At present, in daily life or work, there are often documents that need to be destroyed, so as to prevent others from obtaining the information recorded on the documents. The paper shredder mainly uses groups of shredding blades fixed on two parallel and relatively rotating knife shafts to squeeze waste paper when the two knife shafts rotate at the same time, thereby using the shredding blades on the knife shafts to The waste paper is cut into thin paper strips or shreds, so the quality of the shredding cutter (composed of the cutter shaft and the shredding blade) and the improvement of the production method are particularly important. And the traditional shredding cutter processing method (the method that is about to fix several shredding blades in series ...

AI Technical Summary

Problems solved by technology

Although the paper shredding cutter processed by this method solves the original technical problem without using a spacer ring to fix the blade, in actual production, the rolling cutter also rolls or squeezes the cutter shaft while It will continuously contact the blade and generate a resistance force to the blade along the axial direction of the cutter axis (continuous pressure on the rolling blade), which will easily deform the blade. Deformation or rupture caused by the pressure of the cutter, making the shredding cutter unqualified
