Problems solved by technology

The sheet-fed conveying equipment in the printing machinery currently used in the market is conveyed in the form of the printing side up, especially when processing on the printed product inspection machine and the box gluer, in order to avoid the formation of multiple printed products, it will be placed on the paper when conveying the printed products. The paper knife device, and the friction between the paper knife and the printed product can easily scratch the surface of the printed product, resulting in a decrease in the surface quality of the printed product

Abstract

The invention provides a paper feeder. The paper feeder is characterized by comprising a paper feeding device with an inclined angle alpha and an overturn conveying device, wherein the paper feeding device is arranged at an inlet of the overturn conveying device. The working method comprises the following steps of: adjusting the distance between an inclined paper feeding knife and an inclined sending belt; downwards stacking printing surfaces of printing paper pile at the paper feeding knife and a paper support frame at the front part of equipment; moving the sending belt to transport a single printing product fell on the sending belt to the inlet of the overturn conveying device; feeding the printing products with the downward printing surfaces between an upper pressure belt and a lower pressure belt, and operating the printing products while being clamped by the upper pressure belt and the lower pressure belt, thereby gradually realizing upturning the printing surfaces after the printing products pass through whole transportation path and achieve to an outlet; and conveying the printing products between the upper pressure belt and the lower pressure belt. By the device and the method, an operator can safely stack the printing products outside the equipment, and can conveniently operate; the quality of the printing products can be improved through overturning paper feeding, and the qualified rate of the products can be improved; and the printing products are naturally turned for 180 DEG in the transporting process, and the subsequent processing is not affected.

Description

(1) Technical field: [0001] The invention is suitable for printing equipment using sheet paper as the conveying material, especially suitable for folder-gluing machines or inspection machines that convey printed products with printing surfaces for processing, that is, a paper feeding device and its working method. (2) Background technology: [0002] As people's requirements for commodity printing and packaging are increasing day by day, the surface quality of printed products is particularly important for product packaging. The sheet-fed conveying equipment in the printing machinery currently used in the market is conveyed in the form of the printing side up, especially when processing on the printed product inspection machine and the box gluer, in order to avoid the formation of multiple printed products, it will be placed on the paper when conveying the printed products. The paper knife device, and the friction between the paper knife and the printed matter can easily scra...
