The longitudinal paper feeding device disclosed by the embodiment of the application can be applied to a paper conveying part of a die cutting machine and used for carrying out single-sheet conveying on a longitudinally placed paper stack.
As shown in fig. 1, it is a schematic view of the overall structure of the longitudinal paper feeding device according to the first embodiment of the present application. As can be seen from the figure, the longitudinal paper feeding apparatus of the present embodiment includes:
the paper feeding device comprises a first side plate 101, a second side plate 102, and a driving rotating shaft 103, a paper conveying rotating shaft 110 and a paper suction beam 113 which are arranged between the first side plate 101 and the second side plate 102. The first side plate 101 and the second side plate 102 are arranged in parallel and used for supporting, and two ends of the driving rotating shaft 103, the paper conveying rotating shaft 110 and the paper suction beam 113 respectively penetrate through the first side plate 101 and the second side plate 102.
In this embodiment, the connection portion of the driving shaft 103 and the first side plate 101 and the second side plate 102 is located in the middle of the first side plate 101 and the second side plate 102. The paper conveying rotating shaft 110 is as high as the driving rotating shaft 103, and is located on the outer side of the driving rotating shaft 103, and the paper suction beam 113 is located below the paper conveying rotating shaft 110.
A first driving sprocket 104 is disposed at a first end (an end penetrating through the first side plate 101) of the driving shaft 103, the driving sprocket 104 takes the driving shaft 103 as a shaft and can rotate synchronously with the driving shaft 103, and the driving sprocket 104 and the driving shaft 103 are used as power output devices. A first driven sprocket 105 is disposed at a corresponding position outside the first side plate, and the first driven sprocket 105 is close to the first end of the paper feeding rotating shaft 110 (the end penetrating through the first side plate 101). The first drive sprocket 104 and the first driven sprocket 105 may be in driving connection via a chain or a belt. A roller (not shown in the figure, and particularly see fig. 2) with a lug is arranged on the first driven sprocket 105; the first driven sprocket 105 is eccentrically coupled to one end of a first coupling plate 112, and particularly, a coupling position of one end of the first coupling plate 112 to the first driven sprocket 105 is deviated from a rotation axis of the first driven sprocket 105, and one end of the first coupling plate 112 can rotate with the first driven sprocket 105. The other end of the first connecting plate 112 is connected with a first end of the paper suction beam 113, and a paper suction nozzle 114 is arranged on the paper suction beam 113.

Thus, when the roller with the bump rotates until the bump contacts with the roller 106, the paper feeding rotating shaft 110 swings outwards, and in the process, the included angle between the first connecting swing rod 108 and the vertical direction gradually increases. When the roller with the convex block rotates to a non-convex block part to contact with the roller 106, the paper conveying rotating shaft 110 gradually returns to the initial position under the action of self gravity, in the process, the included angle between the first connecting swing rod 108 and the vertical direction gradually becomes smaller, and finally returns to the initial position, and the included angle between the first connecting swing rod 108 and the vertical direction is 0 degree. Thus, during feeding, the paper feeding rotating shaft 110 swings back and forth, and can periodically press and convey the paper sucked by the paper suction beam 113.
In this embodiment, the second side plate 102 is connected to the driving shaft 103, the paper feeding shaft 110 and the paper suction beam 113 in the same manner as the first side plate 101. In this embodiment, the first ends of the driving rotating shaft 103, the paper feeding rotating shaft 110 and the paper suction beam 113 are all opposite to the first side plate 101, that is, one end close to the first side plate 101 is a first end, and similarly, one end close to the second side plate 102 is a second end. The first end and the second end are not clearly distinguished in structure and are only distinguished for convenience and clarity. Such as the second connecting rocker 109 shown in the figures.

Thus, when the roller with the bump rotates until the bump contacts with the roller 106, the paper feeding rotating shaft 110 swings outwards, and in the process, the included angle between the first connecting swing rod 108 and the vertical direction gradually increases. When the roller with the convex block rotates to a non-convex block part to contact with the roller 106, the paper conveying rotating shaft 110 gradually returns to the initial position under the action of self gravity, in the process, the included angle between the first connecting swing rod 108 and the vertical direction gradually becomes smaller, and finally returns to the initial position, and the included angle between the first connecting swing rod 108 and the vertical direction is 0 degree. Thus, during feeding, the paper feeding rotating shaft 110 swings back and forth, and can periodically press and convey the paper sucked by the paper suction beam 113.
