Problems solved by technology

[0003] In the prior art, when adjusting the distance between the knife and the belt, due to the high requirements on the processing precision of the guide rail and the sliding block matched with it, the up and down adjustment of the paper feeding knife is very difficult, or the paper feeding is difficult due to the pursuit of convenient adjustment and the gap is too large. The accuracy of the knife is affected; the lower part of the paper-feeding knife is flat and often scratches the printing surface of the printed product, resulting in an increase in the unqualified rate of the printed product, which increases the cost, and because the thickness of the paper-feeding knife is less than 20mm, two adjacent The distance between the printed products is small, resulting in double-sheet conveying, which leads to disordered sheets in the subsequent work

Abstract

A paper feeding device is characterized by comprising a slide block, a linear guide rail, an adjusting support plate, a paper feeding cutter, an adjusting bolt, a spring and an adjusting seat, wherein the linear guide rail is connected with the paper feeding cutter, the slide block is fixedly connected with the adjusting seat, or the linear guide rail is connected with the adjusting seat, the slide block is fixedly connected with the paper feeding cutter, the slide block and the linear guide rail are in clearance fit, the adjusting bolt is in threaded fit with the upper part of the adjusting seat, the spring is sleeved on the adjusting bolt and mounted between the adjusting support plate and the adjusting seat, and the adjusting support plate is fixedly connected with the paper feeding cutter. The work method of the paper feeding device comprises the following steps: 1, adjusting paper feeding cutter downwards, rotating the adjusting bolt, moving the paper feeding cutter downwards, and adjusting properly; and 2, adjusting the paper feeding cutter upwards, reversely rotating the adjusting bolt, moving the paper feeding cutter upwards and adjusting properly. The paper feeding device has the advantages as follows: the working end surface of the paper feeding cutter head is circular arc-shaped, so that the quality rate is improved; the thickness of the paper feeding cutter is increased, and the phenomena of double paper pieces are reduced; and by using a linear guide rail pair, the adjusting is convenient, and the actions are smooth.

Description

(1) Technical field: [0001] The present invention is applicable to printing machinery, and is applicable to a kind of equipment and working method thereof, that is, a paper feeding device and its working method, especially for inspection machine equipment and folder-gluer equipment. (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 printing method. [0003] In the prior art, when adjusting the distance between the knife and the belt, due to the high requirements on the processing precision of the guide rail and the sliding block matched with it, the up and down adjustment of the paper feeding knife is very difficult, or the paper feeding is difficult due to the pursuit of convenient adjustment and the gap is too large. The accuracy of the knife is affected; t...
