Abstract

The invention relates to a paper feeder cutter head, which is characterized in that the working end surface of the paper feeder cutter head is in the shape of circular arc; a gas outlet is formed on the lower end surface of the paper feeder cutter head; the angle between a gas outlet hole and a horizontal direction of a printed product is less than 90 degrees; and the lowest position of the circular arc working surface is lower than the lower plane of the gas outlet. The invention also relates to a paper feeder having the paper feeder cutter head, which is characterized by comprising a paper feeder cutter head, a paper feeder cutter and a regulation device, wherein the regulation device consists of slide rails, a regulating handle, a double hole plate, a spring and sliders; and the working method is as follows: regulating the distance between the paper feeder cutter head and a paper conveying belt; blowing out a gas source from an inclined gas outlet of the paper feeder cutter head; and evenly acting the gas flow which is blew out from the inclined gas outlet on the printed product to lead the single printed product to smoothly stick on the paper conveying belt to be conveyed to the next working position. The invention can eliminate surface scratch of the printed product resulted from the shape and position error of mechanical processing assembly and the surface scratch of the printed product caused by warp of part of the printed product resulted from direct-blowing of the gas blowing device.

Description

(1) Technical field: [0001] The present invention is applicable to printing machinery, especially 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 cutter head and a paper feeding device equipped with the paper feeding cutter head and its working method. (two) 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 paper 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, and the feeding principle is to convey the paper through the friction of the belt and the paper blocking action of the paper feeding cutter head Working together...
