[0023] The trigger block 307 is aligned with the control piston 7 , and the trigger block 307 can contact the telescopic end of the control piston 7 when moving.

[0024] like Figures 1 - 9 As shown, after the carton is filled with products, it is placed in the alignment frame 102, and the alignment frame 102 is aligned with the middle of the alignment push rack 402, ensuring that as long as the carton is in the alignment frame 102, the alignment push rack 402 will wrap the carton when it descends; The air pump 409 is controlled by a program to open the electromagnetic valve 410 connected to the outer hanger 408, and the air is input into the lifting piston 5 through the outer hanger 408, so that the alignment frame 4 can be raised; after the carton is placed under the alignment frame 4, the alignment frame 4 is lowered to wrap the carton, the folder 407 is aligned with the fold position of the carton sealing, the electromagnetic valve 410 connected to the lifting piston 201 is opened, and the air pump 409 is started to inflate and extend each group of lifting pistons 201, and then the four groups of alignment push frames 402 are folded to align the carton in the center; Open the solenoid valve 410 connected to the ventilation square pipe B405, and use the air pump 409 to inflate the folding piston 406 connected to the ventilation square pipe B405. First, press the inner flap at the sealed part of the carton flat through the folder 407; Then open the solenoid valve 410 connected to the ventilation square pipe A404, and use the air pump 409 to inflate the folding piston 406 connected to the ventilation square pipe A404. Then, rotate the outer flap at the sealed part of the carton towards the middle through the folder 407. When the outer flap rotates to half, stop rotating the outer flap, close the solenoid valve 410 connected to the ventilation square pipe A404, use the air pump 409 to evacuate air in the reverse direction to reset the folding piston 406 connected to the ventilation square pipe B405, then close the solenoid valve 410 connected to the ventilation square pipe B405, open the solenoid valve 410 connected to the ventilation square pipe A404, extend the folding piston 406 connected to the ventilation square pipe A404, and continue to fold the outer flap of the carton; Through program setting, the above steps can be executed automatically and procedurally for positioning and sealing; Positioning is achieved by setting proximity switches or corresponding sensors. The conveying lead screw 308 is rotated by a motor, the lead screw nut block 306 is driven to move by the conveying lead screw 308, the linkage member 305 is driven to move by the lead screw nut block 306, and then the two sets of fixing frames 301 move as a whole to drive the carton to move; After the carton moves under the sealing machine, it is sealed, and then the carton is moved to another station.

The sealing machine can drive the working direction in a cycle through a motor and adjust according to the feeding position for convenient sealing. The top of the sealing machine is connected by an electric cylinder and can adjust the height as needed; As Figure 5 , the folding piston 406 above the ventilation square pipe A404 is eccentrically arranged, which can achieve a dislocation effect. It can not only ensure the sealing and folding effect, but also avoid interfering with the movement of the folding piston 406 by the sealing machine during the conveying process.

[0026] Embodiment 3: On the basis of Embodiment 1, the linkage member 305 provides a driving effect. Cooperating with the linkage shaft 6 and the synchronous belt, the conveyor belt 101 can be driven to move at a constant speed. At the same time, the trigger block 307 is also in control linkage with the control piston 7. When the trigger block 307 contacts and presses the control piston 7, the hydraulic oil in the control piston 7 is input into the same-side lifting piston 201. The lifting piston 201 is used to push the U-shaped frame 203 downward, and then the fence 202 is pulled down to release the blockade of the conveyor belt 101.

[0027] Specific usage and function of this embodiment: In the present invention, when used, Figure 9 The two ends of the conveyor belt 101 are set as two workstations, and conventional conveyor belts are set on both sides of the workstations for inputting cartons and products and outputting sealed complete cartons; After the carton is filled with products, it is placed in the alignment frame 102, and the alignment frame 102 is aligned with the middle of the alignment push frame 402 to ensure that as long as the carton is in the alignment frame 102, the alignment push frame 402 will wrap the carton when it descends; The air pump 409 is controlled by a program to open the electromagnetic valve 410 connected to the outer hanger 408, and the air is input into the lifting piston 5 through the outer hanger 408, so that the alignment frame 4 can be raised; after the carton is placed under the alignment frame 4, the alignment frame 4 is lowered to wrap the carton, the folder 407 is aligned with the fold position of the carton sealing, the electromagnetic valve 410 connected to the lifting piston 201 is opened, and the air pump 409 is started to inflate and extend each group of lifting pistons 201, and then the four groups of alignment push frames 402 are folded to align the carton in the center; Then open the electromagnetic valve 410 connected to the ventilation square tube B405, use the air pump 409 to inflate the folding piston 406 connected to the ventilation square tube B405, first flatten the inner flap at the carton seal through the folder 407, then open the electromagnetic valve 410 connected to the ventilation square tube A404, use the air pump 409 to inflate the folding piston 406 connected to the ventilation square tube A404, and then rotate the outer flap at the carton seal toward the middle through the folder 407. When the outer flap is rotated to halfway, stop. Stop rotating the outer flap, close the electromagnetic valve 410 connected to the ventilation square tube A404, use the air pump 409 to reversely pump air to reset the folding piston 406 connected to the ventilation square tube B405, then close the electromagnetic valve 410 connected to the ventilation square tube B405, open the electromagnetic valve 410 connected to the ventilation square tube A404, extend the folding piston 406 connected to the ventilation square tube A404, and continue to fold the outer flap of the carton; through program settings, automated process positioning and sealing can be performed; By setting a proximity switch or a corresponding sensor for positioning, the conveying screw 308 is driven by a motor to rotate, the conveying screw 308 drives the nut block 306 to move, the nut block 306 drives the linkage 305 to move, and then the two sets of fixed frames 301 move as a whole, driving the carton to move; when the carton moves to the bottom of the sealing machine, it is sealed, and then the carton is moved to another station, the alignment frame 4 is reset, and the sealed carton is taken out on the other side of the conveying platform 1, and a new carton is placed to realize the cycle; Thus, through reciprocating rotation, the filling and sealing steps can be realized in one station, and the filling personnel can be responsible for the replacement by the way, leaving the tediousness of setting up a separate handling personnel, and two workers can take and put respectively, which can reduce the workload by half; During the movement of the linkage member 305, the synchronous belts outside the two sets of linkage shafts 6 will be driven to move, and then the linkage shafts 6 cooperate with the synchronous belts to drive the conveyor belt 101 to move at a constant speed, and the drive is achieved through unified power; During the movement of the linkage 305, the trigger block 307 also forms a control linkage with the control piston 7. When the trigger block 307 contacts and squeezes the control piston 7, the hydraulic oil in the control piston 7 is input into the lifting and lowering piston 201 on the same side, and the lifting and lowering piston 201 is used to push the U-shaped frame 203 downward, thereby pulling the fence 202 down to release the blockade of the conveyor belt 101. On the contrary, the control piston 7 on the other side is automatically reset by the spring, so that the fence 202 is automatically raised, providing a restriction and prompt effect, automatically releasing it during picking and placing, and automatically enclosing it during work, providing convenience for work.
