The two-way threaded rod 73 is sleeved with two drive plates 74, the two-way threaded rod 73 penetrates through the drive plates 74, the top of each drive plate 74 is sleeved outside the negative pressure pipe 72 and slides along the length direction of the negative pressure pipe 72, two external threads with opposite directions are formed on the two-way threaded rod 73, the two external threads are in threaded fit with the two drive plates 74 respectively, the two drive plates 74 can be driven to be close to or far away from each other through rotation of the two-way threaded rod 73, and driving of the drive plates 74 is achieved. Install magnet one in the inboard of drive plate 74, install magnet two on piston one 76, magnet one and the mutual one side magnetism that is close to of magnet two are opposite, can drive piston one 76 and carry out horizontal migration through the interact of magnet one and magnet two when drive plate 74 carries out horizontal migration, piston one 76 can extract the inside air of negative pressure pipe 72 when removing for a short distance of cardboard tip downstream of top, block the cardboard outside the cardboard of a below when making things convenient for striker plate 9 to be close to each other.

Referring to fig. 5 and 6, a vertical sliding groove 86 is formed in the mounting plate 85, the striker plate 9 comprises a transverse plate 91, a vertical plate 92 and a longitudinal plate 93, a sliding block 88 is fixedly connected to the vertical plate 92, the sliding block 88 is installed in the vertical sliding groove 86 and slides in the vertical direction, two sides of the sliding block 88 abut against the inner wall of the sliding groove 86, a vertical screw 87 is rotatably installed on the mounting plate 85, the bottom of the screw 87 extends into the sliding groove 86 and is in threaded fit with the sliding block 88, the sliding block 88 can be driven by rotating the structure of the screw 87, and the height of the adjusted striker plate 9 is increased. An inclined slope is formed at the end part of the transverse plate 91 far away from the slider 88, the inclined direction of the slope gradually approaches the slider 88 and inclines upwards, and by using the structure of the slope, the transverse plate 91 enters between the paper plates to block a plurality of paper plates above the bottommost paper plate. The transfer and transportation of the paper boards at the bottommost position are convenient.

The embodiment of the application provides a make things convenient for printing machine structure of pay-off, its implementation principle is: the paper boards are conveyed to the upper part of the first conveying belt 11 through the conveying frame 3 and stacked, then the first conveying belt 11 and the second conveying belt 12 are used for feeding the paper boards, and the structure of the stacked paper boards is leveled through the structures of the first pushing plates 61 and the second pushing plates 53 of the leveling mechanism 6.

Under the effect of two-way threaded rod 73, drive plate 74, piston 76 and piston two 83 remove, make two department striker plates 9 be close to each other, negative pressure mechanism 7 bleeds, the cardboard tip of below is partly buckled downwards, several cardboard of striker plate 9 effect below cardboard top shelter from it, make conveyer belt 11 can only act on driving it on a cardboard of below when carrying out the during operation, through above-mentioned structure, realized the orderly material loading of cardboard, promoted work efficiency.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
