Paper feeding device of automatic paper folding machine

Abstract

The invention discloses a paper feeding device of automatic paper folders, which comprises a paper supporting station, a paper twisting and rolling component and a paper propping device, and the paper twisting and rolling component comprises a rolling shaft, a driving gear arranged at one end of the rolling shaft, a main paper twisting wheel arranged in the middle of the rolling shaft, and the bottom part of the main paper twisting wheel is opposite to the paper propping device, and a left and a right auxiliary paper twisting wheel arranged at the rolling shaft and are at intervals with the main paper twisting wheel, and the invention is characterized in that the shore hardness of the plastid of the main paper twisting wheel is 30 to 40 degrees, and the external circle of the main paper twisting wheel is provided with peripheral ribs, and the paper feeding device of the automatic paper folders has the advantages of that: the invention increases the friction of the contact of the main paper twisting wheel and paper smooth surfaces, enlarges the viscosity or absorbability of the main paper twisting wheel to the paper, solves the technical problems that the existing automatic paper folders are bigger in thickness and the paper with big smooth surface cannot be fed smoothly, and widens the application range of the automatic paper folders.

Description

Technical field: [0001] The invention belongs to the origami machine required by the printing industry or office document binding, and mainly relates to an automatic origami machine, specifically a paper feeding device of the automatic origami machine. Background technique: [0002] There are many types, specifications and models of existing automatic paper folding machines, but its basic composition is mainly composed of a frame, a paper feeding device, a paper folding mechanism, a paper output mechanism, a transmission mechanism and an electric control device. Among them, the paper feeding device is installed on the upper front of the frame. The paper feeding device includes a paper support table, a paper pickup roller assembly, and a paper ejector. The paper support table is installed in front of the paper pickup roller assembly. Folded paper; the ejector is installed in the middle of the bottom plate of the paper inlet behind the bottom of the pickup roller assembly; the...

Problems solved by technology

For existing automatic paper folding machines, for papers with thinner thickness and not smooth surface (such as copy paper), the paper feeding device can smoothly feed the paper into the paper folding mechanism for folding, but there is a common problem for paper with thicker thickness. , for paper with a smooth surface (such as: coated paper), the paper feeding device does not feed the paper into the folding mechanism smoothly, and the phenomenon that the pickup roller cannot feed the paper into the folding mechanism often occurs, and the folding efficiency is very low. people cause a lot of trouble
