Folding knife angle adjustment mechanism of origami machine

Abstract

A folding knife angle adjustment mechanism for a folding machine comprises a rack, and further comprises two folding knife mechanisms arranged on the rack symmetrically, wherein each folding knife mechanism comprises a folding knife, a tool rest, a swing guide rod, a folding knife slide block, a linear bearing, a transmission mechanism and a driving mechanism; each folding knife is arranged on the corresponding tool rest; each tool rest is fixedly arranged at one end of the corresponding swing guide rod; one end of each swing guide rod is arranged on the corresponding folding knife slide block; the other end of the swing guide rod is in transmission connection with the corresponding transmission mechanism via the corresponding linear bearing; the driving mechanisms are servo motors; and the drive shaft of each servo motor is in transmission connection with the corresponding transmission mechanism, and drives the transmission mechanism to drive the corresponding folding knife to move up and down. The folding knife angle adjustment mechanism has the advantages that due to swinging angle control of the folding knives, the clearance between the upper folding knife and the lower folding knife can be controlled, so as to avoid extrusion on a material; the cost is reduced; the production period is shortened; the noise is lowered; and the folding efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of filter element processing machinery and equipment, and relates to a folding knife angle adjustment mechanism of a paper folding machine in the production of paper folding filter elements. Background technique [0002] At present, a key process in the manufacture of origami filter elements is to fold the filter element paper into a waveform of a certain height according to various types and models. At present, most of the wave forms of filter element paper are folded by origami machines, and the swinging modes of the folding knife angle in the origami machine mainly include the following two Two ways: 1. Cam structure: the jackknife is opened at a certain angle through the rotation of the cam, the opening angle is the smallest (0 degrees) at the near point, and the largest at the far point. The opening angle of the jackknife is not adjustable and the effective angle is always the maximum opening angle. In...

However, the backlash-free gear mechanism needs to be imported, which has the disadvantages of long delivery period and high cost, so it cannot be widely used.
