The main mechanical structure of automatic carton packaging machine

The main drive system main drive system shown in Figure, the drive route is as follows:
The main drive motor rotates through a pair of sprocket drive shafts I. The clutch Ml is a safety protection device. When the equipment is overloaded, the safety clutch is disengaged and the motor idles. The fixed couplings M2 and M3 connect the shafts I, II, and III together, and two bevel gears and one spur gear fixed on them respectively transmit the power to the three parts:
After the bevel gear Z3 decelerates through the meshing gear Z4, the drive cam rotates, and the groove cam rotates the sprocket Z5 on the shaft X through the link mechanism, and drives the shaft XI through the sprocket overdrive, causing the pair of gears Z7 to drive the teeth. The bar makes a reciprocating movement.
The bevel gear Z8 decelerates and drives the stepping gear box through the gear Z9 meshed therewith, so that the output shaft V is stepped-driven, and then the chain-like transmission drives the step chain to move stepwise. After the gear Z10 decelerates through the gear Zll, it drives the program cam switch to work. The program cam switch controls the working procedure of the system through the micro switch on it. By adjusting the output speed of the main motor, the operating cycle of the system can be adjusted.
Feed conveyor belt drive system The feed conveyor belt drive system is shown in Figure 3. The power source of the feed conveyor chain is a speed-regulating motor. Depending on the container, the motor is also used for different options.
The speed-regulating motor 1 drives the upper shaft to rotate through a pair of sprocket wheels, and the sprocket Z3 installed on the I-axis drives the flat-top chain to move, and the load capacity is fed into the input seat of the packing mechanism with the movement of the link plate.
The motor 2 drives the eccentric to rotate and drives the rocker arm so that the roller frame shakes the container forwards and backwards in the conveying direction, and the irregularly arranged containers just entering the conveyor chain form a regular arrangement.
When the conveyor belt is running, adjusting the output speed of the motor 1 can change the conveying speed of the conveyor belt so that the conveying speed can be in accordance with the operating cycle of the main transmission system.
When changing the number of the roller racks and the number of sub-rails of the unscrambler device and the spacing between them, it is possible to adapt the containers for different combinations of containers.
The paperboard suction cup mechanism The cardboard used for the packaging container is stacked on the paper storage rack. The suction cup is driven by a cylinder. When the suction cup rises to the bottom of the paperboard, the suction sucks the single paperboard onto the suction cup. When the paperboard moves down to the paper storage guide board, the suction cup vacuums. Release, this completes the cardboard attraction.
After the paperboard conveying mechanism paperboard is sucked onto the paper library guide plate, the push rod on the paper pushing mechanism is driven by the cylinder to push the paperboard forward and enter the paper feed system.
Puller drive system shown in Figure 4
The main drive route is: Motor Zl/Z2-I-Z3/z4-II.
The worm deceleration motor drives the upper shaft to rotate through a pair of sprocket wheels. The surface of the output wheel mounted on the I-axis is silicone rubber. The cardboard passes between the output wheel and the bearing on the shaft III, and then enters a pair of teeth. The belt pulley speeds up, and is equipped with a rubber ring roller (roller mounted on the shaft II) and a bearing mounted on the shaft IV. The friction force of the two pairs of rollers pulls the cardboard into position.
Boxing and Preserving Device The boxing mechanism and the bottle keeping device are combined to form a system. The packing head is driven by the cylinder to move half the diameter of the container, so that the containers that have been assembled according to the packing requirements fall on the paperboard that has been transported into place. The bottle keeping device is to keep the continuously fed containers above the head of the packing box. .
Elevator and Slewing Mechanism The lifting plate is installed on the top of the rack. The rack is driven by the main drive system to make it move up and down. It drives the pallets together to rise or fall, rises to the most business point, and supports the packaging cardboard with the container. When staying at the lowest point, the pallets are flush with the slewing channel and the cardboard and containers enter the slewing chain channel. Stepping movement is driven by the stepping gear box driving mechanism in the main transmission system. When the lifting pallet drives the cardboard and the container down to the plane of the turning chain channel, the turning chain drives the carton to move one station.
The glue spraying, folding, pressing, and shaping agencies spray the glue on the top and on both sides. The starting position and length of the glue can be adjusted through the PLC parameter settings. When the top spray glues the bundle, the folding plate under the action of the air cylinder and the crank removes the folding tongue of the carton and covers it. In the next step-feeding process, both side sprays and the folding of both sides of the flap are completed. When the stepping is finished, the carton is in the pause state of the next station. At this time, the upper cover pressurizing mechanism and the side press mechanism perform the compaction of the carton under the action of the cylinder to complete the bonding, so that the finished box is conveyed at the next step. To the exit.
