The supporting frame 3 is also fixed with two symmetrically arranged guide plates 11. A lifting plate 12 is sleeved at one end of the guide plate 11. The lifting plate 12 is used to drive the carrying plate 13 to move upward. A carrying plate 13 is fixed at the bottom of the lifting plate 12. The carrying plate 13 is used to carry paperboard. Two groups of intermittent lifting mechanisms 14 are fixed on the side walls of the feeding rack 7 and the supporting frame 3. The intermittent lifting mechanism 14 can automatically lift the carrying plate 13 for a distance, thereby ensuring the continuous feeding of subsequent paperboards and realizing the automation and continuity of paperboard feeding.

[0026] Specifically, two sliders 8 are fixed on the feeding rack 7, and the two sliders 8 are respectively slidably arranged at the bottom of two slide rails 9, and the two slide rails 9 are installed at the bottom of the support frame 3; the arrangement of the sliders 8 and the guide rails can make the feeding rack 7 more stable when moving back and forth.

[0027] Furthermore, both ends of the feeding rack 7 are sleeved with a pushing plate 10 with a "T"-shaped cross section; the pushing plate 10 can be used to push the top layer of cardboard to move.

[0028] According to the embodiment, the motor 4 is started and the turntable 5 is driven to rotate. The turntable 5 drives the feeding rack 7 to move back and forth through the driving block 6. When the feeding rack 7 moves in the direction close to the conveyor belt 2, under the action of the pushing plate 10, the pushing plate 10 pushes the uppermost cardboard to move until it is pushed onto the conveyor belt 2, and then the conveyor belt 2 transports it to the printing press body 1. When the feeding rack 7 moves in the direction away from the conveyor belt 2, the subsequent cardboard rises to push the pushing plate 10. Then, when the feeding rack 7 is completely reset, the pushing plate 10 falls again under the action of gravity, and then the cardboard feeding work is continued.

[0029] Embodiment 2:

[0030] Combination Figure 2 , Figure 4 and Figure 5 As shown, on the basis of Example 1, the intermittent lifting mechanism 14 includes two mounting rods 141 fixedly connected to the side wall of the feeding rack 7 and a mounting plate 144 fixedly connected to the side wall of the support frame 3, the two mounting rods 141 are both threadedly connected with nuts 142 and a lifting block 143 is detachably mounted through the nuts 142, a fixing sleeve 145 is fixedly provided on the mounting plate 144, a spring 146 is fixedly provided in the fixing sleeve 145 and a limiting block 147 is elastically and movably connected through the spring 146, a reset push rod 148 is fixedly provided on the side wall of the limiting block 147, and the reset push rod 148 is movably connected to a reset hole opened on the side wall of the fixing sleeve 145.

[0031] Specifically, the lifting plate 12 is provided with a plurality of lifting holes which are arranged at equal intervals; the arrangement of the lifting holes can ensure that the lifting plate 12 can be intermittently raised.

[0032] Furthermore, one end of the lifting block 143 is provided with an upward inclined surface, and one end of the limiting block 147 is provided with a downward inclined surface; and they are used to drive the lifting plate 12 to move only in the upward direction.

[0033] According to the embodiment, when the feeding rack 7 moves to push the cardboard, the feeding rack 7 will drive the lifting block 143 to move. After the lifting block 143 enters the lifting hole, it can squeeze the lifting plate 12 to move upward. When the lifting plate 12 moves upward, it will squeeze the limit block 147 to move and make it disengage from the lifting hole. When the lifting plate 12 moves upward by one hole position, under the elastic force of the spring 146, the limit block 147 enters the next hole position to form a limit for the lifting plate 12 to prevent it from moving downward. This cycle is repeated to drive the intermittent upward movement of the supporting plate 13.

[0034] Through the above embodiments, it can be known that the use process of the device is as follows: a pile of cardboards are placed on the carrying plate 13, the motor 4 is started and the turntable 5 is driven to rotate, the turntable 5 drives the feeding rack 7 to move back and forth through the driving block 6, and when the feeding rack 7 moves in the direction close to the conveyor belt 2, under the action of the pushing plate 10, the pushing plate 10 pushes the top layer of cardboard to move until it is pushed onto the conveyor belt 2, and then the conveyor belt 2 transports it to the printing machine body 1, when the feeding rack 7 moves in the direction away from the conveyor belt 2, the subsequent cardboard rises to push the pushing plate 10, and then when the feeding rack 7 is completely reset, under the action of gravity, the pushing plate 10 falls again, and then the cardboard feeding work is continued, and the feeding rack 7 moves. When pushing the cardboard, the feeding rack 7 will drive the lifting block 143 to move. After the lifting block 143 enters the lifting hole, it can squeeze the lifting plate 12 to move upward. When the lifting plate 12 moves upward, it will squeeze the limit block 147 to move and make it disengage from the lifting hole. After the lifting plate 12 moves upward by one hole position, under the elastic force of the spring 146, the limit block 147 enters the next hole position to form a limit for the lifting plate 12 to prevent it from moving downward. This cycle can drive the intermittent upward movement of the carrying plate 13. When all the cardboards are loaded, the reset push rod 148 can be pushed to make the limit block 147 disengage from the lifting hole. Under the action of gravity, the carrying plate 13 and the lifting plate 12 fall down and reset.
