The limiting tray 542 is fixedly arranged on the top of the limiting movable plate 541. The limiting lifting power source 543 is fixedly arranged on the top of the equipment frame 1, and the bottom of the limiting movable plate 541 is fixedly connected to the movable part of the limiting lifting power source 543.

[0091] In this embodiment, the limiting lifting power source 543 is a cylinder.

[0092] Reference Figure 1-Figure 8 As shown, the working method of this device is as follows:

[0093] S1: The cylindrical paper can without the bottom film installed is placed on the receiving mold 22 by an automated device. Specifically, the bottom end of the cylindrical paper can passes through the inner hole of the limiting ring 23 and is arranged in the bearing position 223. At this time, the supporting flange 222 is used to support the bottom end of the cylindrical paper can;

[0094] S2: the first power source 21 drives the supporting turntable 2 to rotate circumferentially so that the accommodating mold 22 moves to the top of the rotating supporting disk 311;

[0095] S3: The third power source 321 drives the rotating arm 322 to rotate counterclockwise upward, so that the glue gun 33 passes through the working through hole 221 into the cylindrical paper can;

[0096] S4: The second power source 313 drives the driving gear 312 to mesh with the transmission rotating support plate 311 to rotate circumferentially, so that the glue gun 33 sprays glue circumferentially around the inner wall of the lower half of the cylindrical paper can to form a bonding portion;

[0097] S5: After the circumferential glue spraying is completed, the third power source 321 drives the rotating arm 322 to reset and drive the glue gun 33 away from the working through hole 221. At the same time, the first power source 21 drives the supporting turntable 2 to rotate circumferentially so that the accommodating mold 22 moves to the bottom of the material passing groove 431-3;

[0098] S6, the transfer power source 422 drives the flip arm 421 to rotate toward the film temporary storage component 41, so that the suction component 423 flips to the extraction position to suck the film 6, and at the same time the separation component 424 blows air toward the extraction position to separate the unabsorbed film from the absorbed film, so as to prevent the flip arm 421 from taking the unabsorbed film away from the temporary storage channel 412-1 when the flip arm 421 moves;

[0099] S7, the translational power source 433 drives the movable receiving plate 432 to move to the first receiving position 431-1, and the transfer power source 422 drives the flipping arm 421 to flip toward the first receiving position 431-1, so that the flipping arm 421 passes through the avoidance strip groove 432-2 and the avoidance through hole 432-1 to absorb the film on the suction component 423 and place it in the film receiving position 435. When the film is located at the film receiving position 435, the top of the movable receiving plate 432 is used to support the bottom of the film;

[0100] S8, the translation power source 433 drives the movable receiving plate 432 to move to the second receiving position 431-2, and at the same time, the lifting power source 413-2 drives the lifting movable plate 413-1 to move vertically upward, so that the stacked films are continuously moved to the extraction position to facilitate the suction component 423 to perform the suction action;

[0101] S9: The lifting power source 442 drives the movable support bar 443 to move vertically downward so that the negative pressure suction cup 444 absorbs the film, and the lifting power source 442 drives the movable support bar 443 to move vertically upward to bring the film away from the film receiving position 435, and then the movable receiving plate 432 is reset to the first receiving position 431-1 to wait for the next work, and at the same time, the flip arm 421 is reset to the extraction position;

[0102] S10: The lifting power source 442 drives the movable support bar 443 to move vertically downward, so that the film passes through the material slot 431-3 to the cylindrical paper can. During the downward movement of the movable support bar 443, the lifting power source 445-1 drives the lifting rod 445-2 to move upward to drive the negative pressure suction cup 444 to be tilted, so that the film is tilted and placed in the cylindrical paper can. When the film is in the cylindrical paper can, the lifting power source 445-1 drives the lifting rod 445-2 to reset and reset the negative pressure suction cup 444 to a horizontal state;

[0103] S11: The negative pressure suction cup 444 sucks and releases the film, and at the same time, the lifting power source 442 drives the movable support bar 443 to move vertically upward to reset. At the same time, the first power source 21 drives the supporting turntable 2 to rotate circumferentially to move the accommodating mold 22 to the bottom of the pressing block 53;

[0104] S12: The limiting lifting power source 543 drives the limiting movable plate 541 to move upward until it abuts against the bottom of the accommodating mold 22. At this time, the limiting tray 542 passes through the working through hole 221 and is set in the cylindrical paper can. Specifically, the setting height of the top of the limiting tray 542 is lower than or flush with the bonding part;

[0105] S13: The pressing and lifting power source 52 drives the pressing block 53 to move downward, thereby driving the bottom film in the cylindrical paper can to be bonded with the bonding part. At this time, the bottom film is supported by the limiting tray 542 to prevent the middle part from being dented, which affects the firmness and aesthetics of the bonding;

[0106] S14: After bonding, the limiting lifting power source 543 and the pressing lifting power source 52 perform reset actions respectively, and the first power source 21 drives the supporting turntable 2 to rotate circumferentially to move the containing mold 22 away from the pressing device 5, and the cylindrical paper can with the film installed is taken out and collected from the containing mold 22 through automated equipment.

[0107] Compared with the prior art, the device realizes automatic bonding of the bottom film and the cylindrical paper can. The bottom film is placed in the cylindrical paper can in an inclined state under the action of the lifting module. Compared with the bottom film being placed in the cylindrical paper can in a horizontal state, the device has the advantages of small shape deformation and no extrusion with the inner circumference of the cylindrical paper can.

[0108] This embodiment realizes automatic extraction and transportation of the film by cooperating with the film lifting module and the film transfer component and the film translation component, thereby optimizing the extraction action and process and improving work efficiency.
