[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0034] The paper output mechanism 100 of this embodiment is as Figures 1 to 6 shown, and includes a paper output base 101 and a plurality of parallel arranged paper feeding conveyor belts 102 installed on the paper output base 101 for feeding cardboard forward. Each paper feeding conveyor belt 102 is driven by a shaft body, and the distance between the plurality of paper feeding conveyor belts 102 can be adjusted manually or electrically. The main improvement is that a paper output lateral width adjustment module 103 and two or more paper jamming modules 104 are arranged above the paper feeding conveyor belt 102. The paper output lateral width adjustment module 103 includes a paper output width adjustment slide rail 1031 horizontally installed on the paper output base 101, two or more paper output width adjustment slide seats 1032 slidably installed on the paper output width adjustment slide rail 1031, and a paper output electric width adjustment driving part 1033 for driving each paper output width adjustment slide seat 1032 to move. Each paper jamming module includes a cardboard 1041 installed on the paper output width adjustment slide seat 1032 and located above the paper feeding conveyor belt 102, and a paper output height adjustment part 1042 for adjusting the height of the cardboard 1041. By adjusting the height of the cardboard 1041 through the paper output height adjustment part 1042, a gap only allowing a single cardboard to pass through is left between the lower end of the cardboard 1041 and the paper feeding conveyor belt 102. The paper output height adjustment part 1042 can be a stud, a micrometer or a gasket, as long as it can slightly adjust the longitudinal position of the cardboard 1041.

[0035] A paper blocking module 105 is provided at the paper feeding end of the paper feeding conveyor belt 102. The paper blocking module 105 includes a paper blocking bracket 1051, a paper blocking plate 1052, and a paper blocking electric driving member 1053. The paper blocking plate 1052 is inclinedly installed on the paper blocking bracket 1051 and arranged facing the cardboard clamping plate 1041, so that the stacked cardboard is inclinedly placed between the paper blocking plate 1052 and the cardboard clamping plate 1041. The bottom cardboard is driven forward by the friction force of the paper feeding conveyor belt 102 through the gap between the lower end of the cardboard clamping plate 1041 and the paper feeding conveyor belt 102. The paper blocking electric driving member 1053 can drive the paper blocking bracket 1051 to move back and forth to electrically adjust the distance between the paper blocking plate 1052 and the cardboard clamping plate 1041 to adapt to cardboard of different lengths.

[0036] In this embodiment, a paper output displacement roller 10534 is provided at the bottom of the paper blocking bracket 1051 to facilitate the overall movement of the paper blocking bracket 1051. Specifically, the paper blocking electric driving member 1053 includes a paper output first motor 10531, a paper output first lead screw 10532, and a paper output first threaded seat 10533. The paper output first lead screw 10532 is rotatably installed on the paper output base 101 via a bearing. The paper output first threaded seat 10533 is sleeved outside the paper output first lead screw 10532. The paper blocking bracket 1051 is fixed to the paper output first threaded seat 10533. The paper output first motor 10531 is used to drive the paper output first lead screw 10532 to rotate.

[0037] In this embodiment, the paper blocking bracket 1051 includes a paper blocking support frame 10511, a paper blocking support rod 10512 arranged along the parallel direction of the multiple paper feeding conveyor belts 102, a paper blocking support block 10513 that is loosely installed on the paper blocking support rod 10512, and a paper blocking extension rod 10515 installed on the paper blocking support block 10513. The paper blocking plate 1052 is installed on the paper blocking extension rod 10515 with an adjustable angle. The paper blocking support block 10513 is provided with a paper blocking opening groove 10514, and the paper blocking opening groove 10514 can tightly clamp the paper blocking support rod 10512.

[0038] In this embodiment, the paper blocking plate 1052 includes a paper blocking portion 10521 and a paper blocking connection portion 10522 that are mutually T-shaped. The paper blocking connection portion 10522 is provided with a paper blocking arc-shaped hole 10523, and a locking member is passed through the paper blocking arc-shaped hole 10523, so that the paper blocking plate 1052 is locked after being adjusted to a preset inclination angle, and the inclination angle of the paper blocking portion 10521 is adjusted to adjust the inclination angle of the stacked cardboard, which is beneficial for smoother paper output.

[0039] In this embodiment, the paper output width-adjusting driving member 1033 includes a second paper output motor 1034, a second paper output lead screw 1035, and a second paper output threaded seat 1036. The second paper output lead screw 1035 is rotatably installed on the paper output base 101 via a bearing. The second paper output threaded seat 1036 is sleeved outside the second paper output lead screw 1035. The paper output width-adjusting sliding seat 1032 is fixed to the second paper output threaded seat 1036. The second paper output motor 1034 is used to drive the second paper output lead screw 1035 to rotate. The thread directions of different second paper output threaded seats 1036 and the second paper output lead screw 1035 are different. When the second paper output lead screw 1035 rotates, the second paper output threaded seats 1036 move in opposite directions, so as to be able to adjust the distance between different second paper output threaded seats 1036 and different paper output width-adjusting sliding seats 1032 to adapt to the conveyance of cardboard of different widths.

[0040] In this embodiment, paper output enclosing plates 106 for blocking both sides of the width of the cardboard are arranged on both side parts of the paper input conveyor belt 102. Specifically, each paper output enclosing plate 106 on each side includes two paper output splicing plate bodies 1061 spliced with each other along the paper input direction. The rear paper output splicing plate body 1061 is detachably arranged. For cardboard with a shorter length, the rear paper output splicing plate body 1061 (the paper output splicing plate body 1061 far from the cardboard clamping plate 1041 side) can be removed to avoid blocking the manual feeding of paper between the cardboard clamping plate 1041 and the paper blocking plate 1052.

[0041] In this embodiment, a dust brush 107 is arranged at the bottom of the rear end of the paper input conveyor belt 102 to brush off dust and foreign matters on the paper input conveyor belt 102.

[0042] In this embodiment, multiple groups of correction conveyor belts 108 are arranged on the front side of the paper input conveyor belt 102, which are used to receive the cardboard conveyed one by one by the paper input conveyor belt 102 and convey it forward. In practice, correction mechanisms can be configured on both sides of the correction conveyor belt 108, such as guide plates that abut against the cardboard, cylinders that push against the cardboard, etc., to correct and convey the cardboard forward. Each group of correction conveyor belts 108 includes a lower correction connecting belt 1081, an upper correction connecting belt 1082, and a connecting driving member for driving the lower correction connecting belt 1081 to move, so as to clamp and convey the cardboard by the lower correction connecting belt 1081 and the upper correction connecting belt 1082.
