Problems solved by technology

[0004] The paper feeding knife used in the prior art and the contact surface of the printed product stacking are vertical (as figure 1 and figure 2 As shown), when the printed products are piled up to a certain height, the pressure between the paper and the belt and between the paper and the paper will increase. In order to effectively control double sheets, it is often necessary to control the gap between the paper knife and the belt to be very small. In this way, the contact pressure between the printing surface of the paper and the paper feeding knife increases, causing scratches on the surface of the product.

Abstract

A paper feeding cutter is characterized in that a working inclined face is arranged on the contact plane of the paper feeding cutter and printing product stacking. An inclined angle is formed between the working inclined face and the vertical face of the paper feeding direction. The working method includes (1) fixing a paper cutter and a connection strip and installing the paper cutter on the paper feeding portion of a printing product to be transmitted; and (2) stacking the printing products in front of the paper feeding cutter, enabling the printing product to lie on the working inclined face of the paper feeding cutter, and delivering a printing product at the lowest end out through the lowest end of the paper feeding cutter. The paper feeding cutter has the advantages that contact pressure between the paper feeding cutter and the paper is released by the inclination angle between the contact plane and the vertical face of the paper feeding direction, and two-paper feeding can be effectively controlled. Surface scratching is reduced, the paper feeding cutter is suitable for the printing products with higher surface quality, and product market competitiveness is improved. The paper feeding cutter is capable of prolonging service life of a belt and the paper feeding cutter.

Description

(1) Technical field: [0001] The invention is applicable to printing machinery, and is applicable to a kind of equipment and its working method in which the belt friction mode is the paper feeding mode, that is, a paper feeding knife and its working method, especially suitable for inspection machine equipment and folder-gluer equipment. (2) Background technology: [0002] With the rapid development of the printing and packaging industry, the lower belt friction paper feeding method has been widely used in automatic folder gluers and printed product quality inspection machines as a fast and effective printed product feeding method. [0003] In the prior art, the paper feeding of the automatic folder-gluer and the printed product quality inspection machine generally adopts the lower belt friction mode as its paper feeding method. The paper actions work together to realize the single-sheet conveying of the cardboard. [0004] The paper feeding knife used in the prior art and th...
