The film forming turntable 12 continues to rotate, and the film disc 5 at the filling station 112 is rotated to the film unloading station 114. The film disc conveyor 4 transports the film disc 5 at the film unloading station 114 to the outside, thereby realizing automatic filling and production of facial masks, improving production efficiency, and realizing mass production.

[0104] The film disk rotating machine 1 realizes the self-forming of the facial mask. When the film forming turntable 12 switches between different workstations, the driving connection between the film forming rotation driving device 14 and the loading plate 13 is separated. When it is necessary to rotate the loading plate 13, the film forming rotation driving device 14 is drivingly connected to the film disk 5. In one embodiment, the film forming rotation driving device 14 is arranged below the film forming turntable 12, and the driving shaft of the film forming rotation driving device 14 can be movably arranged up and down below the filling station 112, so as to be key-connected with the loading plate 13 at the filling station 112.

Under the rotation of the loading turntable 22, Each of the loading racks 23 can reach the transport station 211, the waiting station 212 and the loading station 213 in sequence. The loading and picking device 24 is installed on the loading frame 21 and is located above the loading turntable 22. The loading and picking device 24 is used to transfer the film tray 5 at the loading station 213 to the film tray loading station 111.

[0111] Furthermore, the carrier rack 23 includes a guide rod 231 extending up and down and a carrier seat 232, the top of the carrier seat 232 is used to place the film plate 5, the carrier seat 232 is movably mounted on the guide rod 231 up and down, the loading and lifting mechanism 25 is driven and connected to the carrier seat 232 to drive the carrier seat 232 to move up and down, driving the film plate 5 to move up and down, so that the stability of the carrier plate 13 when moving up and down can be guaranteed, and the carrier plate 13 can be prevented from tilting or shifting during the up and down movement, causing the film plate 5 to fall.

[0112] Preferably, there are multiple guide rods 231, and the multiple guide rods 231 are spaced apart along the circumference of the carrier 232 to define a loading space between the multiple guide rods 231 for loading the film disk 5. In order to ensure that the film disk 5 is aligned and stacked in the upper and lower directions, a loading space is defined between the multiple guide rods 231, and the circumference of each film disk 5 is limited, so that the stacking of the multiple film disks 5 is stable.

[0113] In one embodiment, the film tray loader 2 also includes a loading position detection device 26, which is used to detect the height of the upper film tray 5 at the loading station 213, so that the uppermost film tray 5 is lifted to a suitable height for easy picking up by the loading picking component 242. Specifically, the loading position detection device 26 can be a photoelectric sensor provided on the loading machine frame 21, which is used to detect whether the film tray 5 rises to a predetermined height. When the film tray 5 is lifted to a predetermined height, the loading lifting mechanism 25 stops moving, and the loading picking component 242 moves the uppermost film tray 5 to the film forming turntable 12 for filling process.

[0114] In one embodiment, the film tray loader 2 also includes a loading cam divider 27, which drives the loading turntable 22 to rotate. The loading cam divider 27 can smoothly drive the turntable to rotate and stop the turntable at a suitable position, so that each loading tray 13 is accurately positioned at the transport station 211, the waiting station 212 and the loading station 213, with smooth operation and accurate positioning.
