One end of several shunt air pipes 37 away from the regulating cylinder 35 is connected to a connecting pipe 39, and the other end of the connecting pipe 39 is connected to a gas tank. The detection plate 32 is located in the middle of the printing conveyor belt 2. The number of visual positioning sensors 33 is not less than two, and they are distributed in an array along the length direction of the detection plate 32. In the process of the carton passing through the printing conveyor belt 2, the visual positioning sensor 33 continuously monitors the position of the carton. If there is any deviation, the above adjustment process is repeated to ensure the printing quality.

[0028] The driving member 46 includes a driven gear 461, a driving motor 462, a connecting shaft 463 and a driving gear 464. The driven gear 461 is fixed to the outer side of the bidirectional screw 42, the driving motor 462 is fixed to the front of the body 1, the connecting shaft 463 is fixed to the outer side of the output shaft of the driving motor 462, the driving gear 464 is fixed to the outer side of the connecting shaft 463, and the driving gear 464 is meshed and connected with the driven gear 461. The printing conveyor belt 2 is started, and the adjustment mechanism 3 has adjusted the carton to the appropriate position. The control system operates the driving member 46 of the bidirectional screw 42, and adjusts the position of the positioning frame 44 through the driving motor 462 and the gear system to adapt to cartons of different sizes.

[0029] In this embodiment, a guide rail 47 is fixed to the front of the machine body 1, and slide grooves are provided at the bottom of the two adjustment frames 43, and the two adjustment frames 43 are slidably connected to the outer sides of the guide rail 47 through the slide grooves. The movement of the positioning frame 44 and the support of the roller 45 ensure the precise position of the carton on the printing conveyor belt 2 to prepare for printing. After the carton is accurately positioned, the printing machine starts the printing process to print patterns or texts on the carton. After printing is completed, the carton leaves the positioning mechanism 4.

[0030] The working principle of the above embodiment is:

[0031] (1) When the position of the corrugated carton is adjusted, the visual positioning sensor 33 is started to detect the position of the carton and determine its accurate position. The visual positioning sensor 33 detects the carton passing through the printing conveyor belt 2, obtains the size and position information of the carton, and transmits the detected carton position information to the control system. The control system calculates the amount of adjustment required according to the size and position information of the carton. According to the calculation result, the control system adjusts the air pressure in the shunt air pipe 37 through the control valve 38, and then controls the action of the adjustment cylinder 35 at the corresponding position. The output shaft of the adjustment cylinder 35 pushes the push head 36 to move and extend, so as to push the inclined part of the carton, so that the adjusted carton is guided to the appropriate position of the printing conveyor belt 2 through the introduction plate 34, so as to ensure the accurate alignment of the carton during the printing process. When the carton passes through the printing conveyor belt 2, the visual positioning sensor 33 continuously monitors the position of the carton. If there is any deviation, the above adjustment process is repeated to ensure the printing quality. Once the carton is correctly positioned, the task of the adjustment mechanism 3 is completed, and the carton will continue to pass through the printing conveyor belt 2 into the positioning mechanism 4 for printing.

[0032] (2) When positioning printing is performed on corrugated paperboard, the printing conveyor belt 2 is started, and the adjustment mechanism 3 has adjusted the paperboard to the appropriate position. The control system operates the driving member 46 of the bidirectional screw 42 to adjust the position of the positioning frame 44 by driving the motor 462 and the gear system to adapt to paperboards of different sizes. The adjustment frame 43 slides on the guide rail 47 through the slide groove to drive the positioning frame 44 to move to the appropriate position of the paperboard. The roller 45 in the positioning frame 44 can rotate with the movement of the paperboard to support and stabilize the paperboard to ensure the smooth movement of the paperboard on the printing conveyor belt 2. The movement of the positioning frame 44 and the support of the roller 45 ensure the precise position of the paperboard on the printing conveyor belt 2 to prepare for printing. After the paperboard is accurately positioned, the printing press starts the printing process to print patterns or texts on the paperboard. After printing is completed, the paperboard leaves the positioning mechanism 4.
