[0035] Specifically, in order to realize the conveying of the square blister box to the inside of the automatic crimping mechanism 202 for crimping processing, the vertical moving component 2013 drives the suction cup component 2015 to move downward through the fixed frame 2014, and the suction cup component 2015 adsorbs and fixes the square blister box on the automatic feeding device 3, and then the vertical moving component 2013 drives the suction cup component 2015 to reset, and at this time, the horizontal moving component 2011 drives the suction cup component 2015 adsorbed with the square blister box to move horizontally through the fixed plate 2012.

[0038] Specifically, in order to improve the anti-falling property of the device when it is sucking and moving the square blister box, when vacuum suction is generated inside the suction cup assembly 2015, the telescopic sleeve 5 will drive the limit plate 501 to move at its telescopic end under the action of the suction force, and the limit plate 501 will be inserted between the two groups of square blister boxes. The limit plate 501 can limit the edge position of the square blister box. The limit plate 501 can prevent the suction cup assembly 2015 from falling off when the square blister box is moved, thereby improving the anti-falling property of the device when it is sucking and moving the square blister box.

When the interior of the square blister box is uneven due to shape, when the suction cup assembly 2015 moves downward to adsorb and fix the square blister box, it will cause the connection point between the connecting column 601 at the top of the connecting suction cup 602 and the connecting plate 6 to rotate, so that the bottom end of the connecting suction cup 602 can fit against the inner wall of the square blister box, thereby better adsorbing and fixing the square blister box.

The mold feeding mechanism 2021 is provided with a plurality of rollers for conveying the square curling mold 2027, which can increase the convenience of the staff to manually install and disassemble the square curling mold 2027. On the production line, the square curling mold 2027 is installed by using the mold feeding mechanism 2021. After the square curling mold 2027 is installed, the mold feeding mechanism 2021 is moved away, and the automatic feeding device 3 is placed on the mold.

The movable mold is fixedly connected with the lifting seat 2024 through the movable mold fixing mechanism 2025, and the fixed mold is fixedly installed through the fixed mold fixing mechanism 2026.

[0044] Specifically, in order to realize the curling processing of the square blister box, the mold feeding mechanism 2021 is used to transport the square curling mold 2027, so that the worker can install the square curling mold 2027 conveniently, the lifting drive mechanism 2023 is used to drive the lifting seat 2024 to move, the movable mold fixing mechanism 2025 and the fixed mold fixing mechanism 2026 are used to fix the square curling mold 2027.

The drive assembly 403 is composed of a motor and a conveyor belt, and its conveying end is connected to the conveyor belt assembly 402.

[0046] Specifically, in order to realize the conveyance of the square plastic box formed by the curling process, when the square plastic box formed by the curling process is placed on the surface of the conveyor belt assembly 402, the conveyor belt assembly 402 is driven to move by the driving assembly 403, and the square plastic box formed by the curling process can be conveyed by the conveyor belt assembly 402.

[0047] Working principle: The square curling mold 2027 is transported by the mold feeding mechanism 2021, and the worker installs the square curling mold 2027. After the square curling mold 2027 is installed, the mold feeding mechanism 2021 is moved away, and then the conveying frame 1 301 is placed at the position of the mold feeding mechanism 2021. By stacking multiple square blister boxes on the fixed frame 2 303, the fixed frame 2 303 and multiple square blister boxes can be transported to the bottom of the suction cup assembly 2015 through the conveying assembly 302. At this time, the suction cup assembly 2015 is driven to the fixed frame 1 2014 through the vertical moving assembly 2013. When the suction cup assembly 2015 moves downward to absorb and fix the square blister box on the automatic feeding device 3, the connection point between the connecting column 601 connecting the top of the suction cup 602 and the connecting plate 6 will rotate, so that the bottom end of the connecting suction cup 602 can fit with the inner wall of the square blister box, so as to better absorb and fix the square blister box. At the same time, when the vacuum suction force is generated inside the suction cup assembly 2015, the telescopic sleeve rod 5 will drive the limit plate 501 to move under the action of the suction force, and the limit plate 501 will be inserted between the two groups of square blister boxes. The edge of the square blister box is limited and prevented from falling off, and then the suction cup assembly 2015 is reset by the vertical moving assembly 2013. At this time, the suction cup assembly 2015 with the square blister box adsorbed thereon is driven to move horizontally through the fixed plate 2012 by the horizontal moving assembly 2011. The fixed plate 2012 moves along the guide seat 101 until the square blister box is located at the curling processing position inside the automatic curling mechanism 202. Then, the suction cup assembly 2015 is driven to move downward by the vertical moving assembly 2013 through the fixed frame 1 2014. The suction cup assembly 2015 places the square blister box in the square curling mold 2027. When the mold is fixed, the lateral moving component 2011 drives the suction cup component 2015 to reset, and then the lifting drive mechanism 2023 works to drive the movable mold in the square curling mold 2027 to move via the lifting seat 2024, so that the square blister box can be stamped and curled inside the square curling mold 2027, and then the unloading adsorption mechanism 203 adopts the same method as above to transport the square blister box curled inside the square curling mold 2027 to the surface of the conveyor belt component 402. At this time, the conveyor belt component 402 is driven to move by the driving component 403, and the conveyor belt component 402 moves to transport the square plastic box after the curling process.
