Figure 6 As shown, the interface guide mechanism includes an interface guide rod 1.2, an interface guide frame 1.3, an interface material collection plate 1.4, an interface material collection plate translation assembly, and an interface blocking cylinder 1.5. The interface vibrating plate, interface guide rod, interface guide frame, interface material collection plate, and interface loading mechanism are arranged sequentially along the interface movement direction. The interface vibrating plate is existing technology and can be purchased externally.

[0094] The interface guide rod, the interface guide frame, and the interface blocking cylinder are all fixed to the main frame through a bracket (omitted in the figure).

[0095] like Figure 10As shown, the upper part of the interface guide rod is a guide plate 1.21 and the lower part is a suspension rod 1.22, the bottom edge of the guide plate is connected to the suspension rod, the outer diameter of the suspension rod is larger than the thickness of the guide plate, the interface guide rod is arranged obliquely, one end of the interface guide rod is docked with the outlet of the interface vibration disk, and the other end of the interface guide rod is docked with the inlet of the interface guide frame, and the end of the interface guide rod close to the interface vibration disk is higher than the end close to the interface guide frame.

The loading gripper connecting plate is fixed to the loading gripper slider, and the loading gripper slider is fixed to the piston rod of the interface translation cylinder.

[0099] The working principle of the first feeding device is as follows:

[0100] 1. The interface vibration plate is equipped with interfaces. The interface vibration plate generates vibration to arrange the interfaces neatly (the dosing tube and infusion tube of the interface are upward, and the base of the interface is downward) and transport them to the interface guide rod. When the interface passes through the interface guide rod, it is directly hung on the hanging rod ( Figure 10As shown, the guide plate on the suspension rod can prevent the interface from swinging left and right) and the interface slides toward the interface guide frame under the action of gravity. The interface then slides into the interface guide frame through the interface inlet and falls downward (blocked by the blocking rod);

[0101] 2. When a certain number of interfaces are stored in the interface guide frame, the blocking cylinder is activated and the blocking rod is retracted from the interface guide frame ( Figure 10 ), while the interface aggregate plate translation assembly drives the interface aggregate plate to move horizontally ( Figure 10 The interfaces fall downwards into the grooves of the interface aggregate plate and are brought forward by the interface aggregate plate (arrow direction). Figure 11 ), the blocking rod then extends into the interface guide frame to block the interface;

[0102] 3. The interface feeding mechanism starts, grabs all interfaces on the interface collecting plate together and puts them on the support seat of the first turntable (the support seat closest to the first feeding mechanism); the interface translation cylinder drives the feeding gripper to move to the interface collecting plate ( Figure 11 The loading gripper grabs all the interfaces on the interface aggregate plate at the same time, and the interface translation cylinder drives the loading gripper to move above the support seat (the support seat closest to the second loading mechanism), and the loading gripper places the interface on the support seat.

[0103] 3. Second loading device

[0132] A retracting mechanism is provided on each side of the sealing and cutting mechanism. Figure 23 ).like Figure 25 As shown, the retractable mechanism includes a retractable frame 5.71, a retractable motor 5.72, an aluminum-plastic film positioning assembly, and a retractable guide wheel 5.73.

[0134] The working principle of the film sticking device is as follows:

[0135] 1. The two retracting and releasing mechanisms work simultaneously, releasing and rewinding the aluminum-plastic film respectively. The aluminum-plastic film passes between the sealing and cutting plate and the punching plate;

[0136] 2. The aluminum-plastic film stops moving, the sealing and cutting mechanism works, and the sealing and cutting motor drives the sealing and cutting lifting frame to move up and down through the sealing and cutting transmission mechanism.
