Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A printing machine for carton processing: comprising a conveying platform 1, a printing device 11 is arranged on the surface of the conveying platform 1, a loading platform 12 is fixedly connected to one side of the conveying platform 1, a discharge mechanism is arranged on the other side of the conveying platform 1, the discharge mechanism comprises a mobile discharge vehicle 2, the mobile discharge vehicle 2 is contact-connected to one side of the conveying platform 1, a first connection block 21 is fixedly connected to the surface of the mobile discharge vehicle 2, a connection rod 22 is movably connected to the surface of the first connection block 21, a second connection block 23 is fixedly connected to the surface of the conveying platform 1, a first motor 24 is fixedly connected to the surface of the conveying platform 1, and an output shaft of the first motor 24 is movably connected to the output shaft of the first motor 24. A ball screw 25 is fixedly connected, and the first motor 24 drives the ball screw 25 to rotate through the output shaft. A first nut 26 is threadedly connected to the surface of the ball screw 25, and a lifting plate 27 is fixedly connected to the surface of the first nut 26. A cylinder 28 is fixedly connected to the surface of the mobile unloading cart 2, and a push plate 29 is fixedly connected to the piston rod of the cylinder 28. A protective cushion 210 is adhered to the surface of the mobile unloading cart 2. The unloading mechanism can automatically collect processed cartons to avoid cartons piling up on the unloading platform, avoid clogging of the unloading platform, reduce the trouble of manual unloading, and save workers time and effort.

[0024] Furthermore, a limiting mechanism is arranged on the surface of the conveying platform 1, and the limiting mechanism includes a guide rod 3, which is fixedly connected to the surface of the conveying platform 1, and a guide block 33 is slidably connected to the surface of the guide rod 3. A second motor 31 is fixedly connected to the surface of the conveying platform 1, and a bidirectional screw rod 32 is fixedly connected to the output shaft of the second motor 31. The second motor 31 drives the bidirectional screw rod 32 to rotate via the output shaft, and a second nut 34 is threadedly connected to the surface of the bidirectional screw rod 32, and the bottom of the second nut 34 is fixedly connected to a limiting plate 35, and the guide block 33 is fixedly connected to the surface of the limiting plate 35. The original limiting mechanism adopts manual operation to adjust the position of the limiting plate 35, and the position of the limiting plate 35 of the carton needs to be adjusted to adapt to the changes of different cartons. The limiting mechanism can automatically adjust the position of the two sets of limiting plates 35, thereby improving the efficiency of adjusting the position of the limiting plate 35.

[0025] Furthermore, guide holes are provided on the surfaces of the first connecting block 21 and the second connecting block 23, and the connecting rod 22 is in a "J" shape. The connecting rod 22 passes through the circular hole of the second connecting block 23. The first connecting block 21 and the second connecting block 23 restrict the conveying platform 1 and the mobile unloading cart 2 together through the connecting rod 22, so as to facilitate the installation and disassembly of the mobile unloading cart 2 on one side of the conveying platform 1, thereby facilitating the transportation of cartons on the mobile unloading cart 2 to other places.

[0026] Furthermore, all guide holes are opened on the surface of the mobile unloading cart 2, and two groups of first nuts 26 are provided. The first nut 26 is rotated by the ball screw 25 to slide on the guide hole of the mobile unloading cart 2. The first nut 26 drives the lifting plate 27 to rise and fall on the surface of the mobile unloading cart 2. The horizontal height of the cylinder 28 is always lower than the horizontal height of the cartons transported by the mobile unloading cart 2. The mobile unloading cart 2 will transport the cartons to the surface of the lifting plate 27, and the cartons will be stacked together on the cylinder 28. During the stacking process of the cartons, the lifting plate 27 will continue to descend, so that the height of the carton at the top of the lifting plate 27 is lower than the horizontal height of the cartons on the surface of the mobile unloading cart 2.

[0027] Furthermore, the cylinder 28 drives the push plate 29 to move above the conveying platform 1 through the piston rod. Two groups of push plates 29 are provided, and the push plates 29 are in an "L" shape.

[0028] Furthermore, the guide rod 3 and the bidirectional screw rod 32 are parallel to each other. The bidirectional screw rod 32 drives the second nut 34 to move by rotation. The limit plate 35 moves on the surface of the conveying platform 1 through the second nut 34. The limit plate 35 changes the limit position of the carton during the movement, thereby facilitating the adjustment of the limit position of the limit plate 35.

[0029] Furthermore, two groups of limit plates 35 are provided, and the two groups of limit plates 35 can slide and adjust their positions at the same time, thereby improving the efficiency of position adjustment of the limit plates 35. The two sides of the limit plates 35 are bent outward to facilitate guiding the cartons. The guide blocks 33 slide on the guide rods 3 to guide the movement of the limit plates 35, thereby ensuring the stability of the limit plates 35 moving on the surface of the conveyor platform 1.

[0030] Working principle: Move the mobile unloading cart 2 to one side of the conveying platform 1, slide the connecting rod 22 on the first connecting block 21, so that the connecting rod 22 passes through the circular hole of the second connecting block 23, and the first connecting block 21 and the second connecting block 23 restrict the conveying platform 1 and the mobile unloading cart 2 together through the connecting rod 22. After the cartons on the conveying platform 1 are printed, they will be transported to the mobile unloading cart 2. The lifting plate 27 on the mobile unloading cart 2 will catch the cartons. Due to the high height of the push plate 29, the cartons will not contact the push plate 29 during the movement. When one side of the carton reaches the push plate 29 and the other side is on the conveying platform 1, since the height of the lifting plate 27 is lower than the surface of the conveying platform 1, The carton is tilted, and the top of the carton is in contact with the piston rod of the cylinder 28. The cylinder 28 drives the push plate 29 to move through the piston rod. The push plate 29 drags the carton to the surface of the lifting plate 27 during the movement. The protective cushion 210 prevents the carton from being damaged by collision. The push plate 29 returns to its original position at this time, and the first motor 24 drives the ball screw 25 to rotate through the output shaft. The ball screw 25 drives the first nut 26 to move, and the first nut 26 drives the lifting plate 27 to descend, so that the height of the carton on the top of the lifting plate 27 is lower than the height of the surface of the conveying platform 1. The cartons on the conveying platform 1 will be continuously stacked on the surface of the lifting plate 27, and no manual unloading is required, saving time and effort.

[0031] The bidirectional screw rod 32 is driven to rotate by the output shaft of the second motor 31, and the bidirectional screw rod 32 drives two sets of second nuts 34 to move on the surface of the conveying platform 1, and the second nuts 34 drive two sets of limit plates 35 to move on the surface of the conveying platform 1. The guide block 33 guides the moving direction of the limit plate 35 by sliding on the guide rod 3. The two sets of limit plates 35 move in different directions at the same time, which improves the efficiency of adjusting the limit plate 35.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
