Description

Technical Field

[0001] The utility model relates to the technical field of paper printing, in particular to a paper feeding mechanism for a folding machine. Background Art

[0002] The development of science and technology has promoted the development of the printing industry. The offset rotary printing method has replaced the old lead and fire printing method, which is another great progress of human civilization. The production lines of paper printing include Kolbus softcover binding line, Kolbus hardcover line, Otto 780 folder, Huayue 1370 paper cutter and other production lines. Therefore, there is a folding process in the printing production, so it is necessary to input the folded paper into the folder one by one through the paper feeding mechanism. The existing paper feeding device mainly rolls the paper in through the roller rolling. During the rolling process, it is very common to roll several pages of paper in at the same time, and the paper rolling in cannot be controlled. The scrap rate of paper is high, which will also cause paper jams and production interruptions. Manual adjustment is required, which is time-consuming and labor-intensive, and has low production efficiency.

[0003] Patent No. CN203306772U in the prior art discloses a paper feeding device for a printing folding machine, which can quickly feed paper into the folding machine, place a stack of paper on the base, release the handle, the handle just presses on the corners of the paper, blow air into the L-shaped air pipe, and the air blows out from the air nozzle, the middle of the paper is blown up, the middle of the paper is lifted up, the paper on the top layer is sucked by the vacuum suction cup, and the paper pressing sheet presses the paper on the lower layer. At the same time, rollers, paper pressing rods and paper pressing sheets are designed to ensure accurate paper feeding, and multiple sheets of paper will not be fed at one time. The corners of the paper are not easy to roll up. Compared with the old paper feeding device, the feeding is fast and continuous, the automation level is high, the production efficiency is high, and the yield rate is high, which effectively solves the problem of paper jam during paper feeding. However, in actual use of the prior art, air is blown out from the air nozzle, the middle part of the paper is blown up, and the paper is pressed down by the paper pressing rod and the paper pressing sheet to limit the position. As a result, when a stack of paper is conveyed less and less, the distance between the paper and the vacuum suction cup becomes farther and farther, which makes it difficult to stably suck the paper by the suction cup for conveying, thereby affecting the overall use effect.
