The specific embodiment

Below in conjunction with accompanying drawing to further explain of the present invention:

As shown in the figure: a kind of paper guide of batch type printing machine comprises forebay 1, afer bay 2, crossbeam 3, interior paper feed mechanism 4, paper web 5.

Forebay 1 is arranged crossbeam 3 with the top of afer bay 2, and interior paper feed mechanism 4 is arranged in the forebay 1, arranges paper web 5 respectively in forebay 1 and the afer bay 2.

Interior paper feed mechanism 4 comprises frame plate 41, last fine setting axle 42, following fine setting axle 43, upward defeated paper roller bearing 431, following defeated paper roller bearing 432, last micro actuator 44, following micro actuator 45, tensioning frame 46, last cut-off knife 49, middle cut-off knife 50, following cut-off knife 51.

Frame plate 41 is two, and last fine setting axle 42 and following fine setting axle 43 are arranged in close frame plate 41 edges between the frame plate 41, last fine setting 44 outside that are arranged in an end frame plate 41 of fine setting axle 42, and following micro actuator 45 is arranged in down the outside of an end frame plate 41 of finely tuning axle 43; Going up defeated paper roller bearing 431 is arranged above and below with following defeated paper roller bearing 432; And be arranged in fine setting axle 42 and finely tune between the axle 43 down; Last cut-off knife 49 is arranged in the top of fine setting axle 42 and in parallel; Following cut-off knife 51 is arranged in down the below of fine setting axle 43 and in parallel; The edge of a knife of last cut-off knife 49 and following cut-off knife 51 is all towards a side, and middle cut-off knife 50 is arranged between the edge of a knife of cut-off knife 49 and following cut-off knife 51.

Tensioning frame 46 comprises two frame plates, 461, the first pressure rollers, 462, the second pressure rollers, 463, the three pressure rollers 464, swing arm 465, tensioning pressure roller 466, tensioning cylinder 47, cylinder 48, leg 467.

First pressure roller 462, second pressure roller 463 and the 3rd pressure roller 464 are arranged in parallel between two frame plates 461; Swing arm 465 is arranged in the outside of two frame plates 461; One end of two swing arms 465 be connected with tensioning cylinder 47 other end and between arrange tensioning pressure roller 466; 467 one-tenth " L " shapes of leg; Leg 468 is fixing with one of them frame plate 461, and cylinder 48 is connected with leg 467.

In this mechanism, mainly by scale up and down, up and down deviation correction mechanism, mechanism for cutting sheet, secondary expansion mechanism, secondary storage mechanism of paper and storage mechanism of paper are formed up and down.Wherein scale, deviation correction mechanism, mechanism for cutting sheet alternate turns work up and down up and down up and down.Existing is its course of work of example explanation with lower mechanisms work:

Paper, travels forward through secondary expansion mechanism, secondary storage mechanism of paper and storage mechanism of paper under the drive of expansion mechanism driving force through after correction machine, lower steering roll get into the gap of going up between the lower steering roll down successively.Wherein, the secondary expansion mechanism keeps going up the constant tension between lower steering roll and the storage mechanism of paper through the swelling air bag, and secondary storage mechanism of paper then is the service of secondary expansion mechanism, and this mechanism is by driven by servomotor.

When a chart drum when using up; Send instruction by controlling organization, paper is cut off in following mechanism for cutting sheet work; The paper web that a volume is new is upward devoted oneself to work in the gap between the lower steering roll through last guide roller entering simultaneously, thereby guarantees the operate as normal of whole print stream waterline.
