Preferably, the farthest vertical distance from the vertical plane of the third vertical section 1006 to the second circular arc section 1003 is equal to the length of the rocker arm 982, so that when the rocker arm pulley 983 slides from the top end of the limiting chute 100 to the center of the second circular arc section, the rocker arm pulley 983 drives the rotating shaft 97 to rotate 90 ° relative to the vertical sliding table 95 for feeding the paper cards through the rocker arm 982, so that the pneumatic suction head 981 for feeding the paper cards synchronously turns 90 °. Furthermore, the limiting sliding groove 100 is disposed in an axisymmetric manner with respect to the center line of the second circular arc segment 1003, so that when the rocker pulley 983 moves from the top end of the limiting sliding groove 100 to the bottom end thereof, the paper card feeding pneumatic head 981 can turn 180 ° with respect to the paper card feeding vertical sliding table 95, that is, the suction end of the paper card feeding pneumatic head 981 can turn from vertical upward to vertical downward, so as to smoothly move the paper card from the hopper 93 to the plastic box of the plastic box positioning groove 22.
When the index plate 2 drives the discharging seat 21 to move to the paper card feeding station C, the paper outlet 931 of the hopper 93 is located right above the plastic box positioning groove 22, when a paper card is fed, the paper card feeding pneumatic head 981 firstly sucks the paper card located at the bottommost end of the hopper 93, then, the paper card feeding vertical cylinder 96 drives the paper card feeding vertical sliding table 95 to vertically move down along the paper card feeding vertical sliding rail 94, at the same time, the rotating shaft 97 and the rocker arm 982 synchronously move down along with the paper card feeding vertical sliding table 95, in the process, the rocker arm pulley 983 on the rocker arm 982 also slides along the limiting sliding groove 100, under the matching action of the rocker arm pulley 983 and the limiting sliding groove 100, the rocker arm pulley 983 drives the rotating shaft 97 to rotate relative to the paper card feeding vertical sliding table 95 through the rocker arm 982, the fixed seat 98 drives the paper card feeding pneumatic head 981 to synchronously turn over, so that the paper card feeding pneumatic head 981 is aligned with the plastic card positioning groove 22 at the plastic card feeding end of the paper card feeding pneumatic head 981 (namely, when the paper card feeding pneumatic head 981 is successfully turned over, the paper card feeding pneumatic head 981 is also turned over again, and the paper card feeding pneumatic head 981 is turned over the paper card feeding pneumatic head 981 and then the paper card feeding sliding table 981 is turned over again, and the paper card feeding pneumatic head is turned over on the plastic box positioning groove 981, and the paper card is again, and the paper card feeding pneumatic sliding table 981 is again, and then the paper card is again, and the paper card feeding pneumatic head is turned over the paper card feeding pneumatic sliding table 981 is turned over.
In the embodiment, referring to fig. 14, the heat sealing packaging mechanism 10 includes a heat sealing mounting seat 101 disposed on a base 1, a heat sealing vertical sliding rail is disposed on the heat sealing mounting seat 101, the heat sealing vertical sliding rail is movably provided with a heat sealing vertical sliding table 103, the heat sealing vertical sliding table 103 is driven by a heat sealing vertical cylinder 104 to slide back and forth along the heat sealing vertical sliding rail, and the heat sealing vertical sliding table 103 is fixedly connected with a heat sealing heating seat 105; when the index plate 2 drives the material placing seat 21 to enter the heat sealing and packaging mechanism 10, the heat sealing vertical air cylinder 104 drives the heat sealing vertical sliding table 103 to move downwards, and the heat sealing and heating seat 105 performs heat sealing and packaging on the plastic box and the paper card to form the packaging box.
In this embodiment, referring to fig. 15, the discharging mechanism 11 includes a discharging mounting base 111 disposed on the base 1 and a discharging conveyor belt 112 disposed corresponding to the discharging mounting base 111, a discharging transverse slide rail 113 is fixed on the discharging mounting base 111, a discharging transverse slide rail 114 is movably disposed on the discharging transverse slide rail 113, the discharging transverse slide rail 114 is driven by a discharging transverse cylinder 115 to slide back and forth along the discharging transverse slide rail 113, the discharging transverse slide rail 114 is fixedly connected with a discharging vertical cylinder 116, a discharging base 117 is fixed at an output end of the discharging vertical cylinder 116, and a discharging pneumatic suction head 118 corresponding to a plastic box positioning groove of the corresponding discharging base 21 is mounted on the discharging base 117; when the index plate 2 drives the corresponding discharging seat 21 to move to the discharging station E, the discharging pneumatic suction head 118 sucks up the packaging box in the corresponding plastic box positioning groove, and transfers the packaging box to the discharging conveying belt 112 under the matching action of the discharging vertical cylinder 116 and the discharging horizontal cylinder 115.
The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present invention are included in the scope of the present invention.
