[0037] The working principle of this utility model:

[0038] Two cosmetic packaging bottles are placed manually in the contoured grooves 305 of the two carriers 304, respectively. The first motor 303 works, and the turntable 301 is driven to rotate intermittently through the cam divider 302. The multiple carriers 304 installed on the turntable 301 also rotate, so that the turntable 301 intermittently transports the cosmetic packaging bottles, and stops rotating after the cosmetic packaging bottles are transported to the bottom of the packaging bottle detection mechanism 4. The first photoelectric sensor 402 detects the cosmetic packaging bottles in the carrier 304. When the first photoelectric sensor 402 cannot detect the cosmetic packaging bottles, the first motor 303 does not work. When the first photoelectric sensor 402 detects that there are cosmetic packaging bottles in the carrier 304, the first photoelectric sensor 402 transmits the detected signal to the carrier 304. To the PLC controller, the PLC controller controls the first motor 303 to continue working to drive the turntable 301 to rotate, and the cosmetic packaging bottle is transported to the bottom of the aluminum film feeding mechanism 5 and then stops rotating. The first cylinder 5102 is actuated to push the support plate 5103 to move, and the first suction cup mounting plate 5104 and the first vacuum suction cup 5105 also move accordingly, so that the first vacuum suction cup 5105 contacts the aluminum film, and the vacuum pump is turned on to make the first vacuum suction cup 5105 generate negative pressure to adsorb the aluminum film at the bottom of the aluminum film bin. After the adsorption is completed, the first cylinder 5102 is actuated to reset, driving the first vacuum suction cup 5105 to move, and the aluminum film at the bottom of the aluminum film bin is extracted. The rotating cylinder 5108 works to drive the flip shaft 5107 to rotate 180 degrees clockwise, and the flip plate 5101 is turned on. The first cylinder 5102 and the second cylinder 5112 on the flip plate 5101 also rotate clockwise, so that the first cylinder 5102 rotates to the top of the carrier 304, and the first cylinder 5102 moves the first vacuum suction cup 5105 and the aluminum film to the cosmetic packaging bottle in the carrier 304, and the vacuum pump is turned off. The first vacuum suction cup 5105 releases the aluminum film, and the aluminum film falls onto the cosmetic packaging bottle. The first motor 303 works to drive the turntable 301 to rotate, and the cosmetic packaging bottle with the aluminum film is transported to the bottom of the aluminum film detection mechanism 6 and then stops rotating. The second photoelectric sensor 601 detects the aluminum film on the cosmetic packaging bottle. When the second photoelectric sensor 601 cannot detect the aluminum film, the first motor 303 does not work. When the sensor 601 detects that there is an aluminum film on the cosmetic packaging bottle, the second photoelectric sensor 601 transmits the detected signal to the PLC controller, and the PLC controller controls the first motor 303 to continue working to drive the turntable 301 to rotate, and the cosmetic packaging bottle is transported to the bottom of the heat sealing mechanism 7 and then stops rotating. The fourth cylinder 709 is actuated to push the L-shaped lifting plate 708 to move downward, and the pressing plate 704, the heat sealing head mounting seat 702 and the heat sealing head 701 also move downward, so that the heat sealing head 701 abuts against the cosmetic packaging bottle with the aluminum film. At this time, due to the elastic force of the spring 706, the heat sealing head 701 always abuts against the cosmetic packaging bottle with the aluminum film, avoiding the heat sealing head 701 from colliding with the cosmetic packaging bottle, which causes damage to the cosmetic packaging bottle.The heating tube works to transfer heat to the heat sealing head 701, and the heat sealing head 701 transfers heat to the aluminum film, so that the aluminum film adheres to the cosmetic packaging bottle, thereby achieving the sealing of the cosmetic packaging bottle. After the sealing is completed, the first motor 303 continues to work to drive the turntable 301 to rotate, and the cosmetic packaging bottle is transported to the bottom of the transfer mechanism 8 and then stops rotating. The fifth cylinder 806 moves to push the third suction cup mounting plate 802 and the third vacuum suction cup 801 to move downward, so that the third vacuum suction cup 801 abuts against the cosmetic packaging bottle, and the vacuum pump is turned on to make the third vacuum suction cup 801 adsorb the cosmetic packaging bottle. After the adsorption is completed, the fifth cylinder 806 is reset, and the sixth cylinder 812 is actuated The moving plate 805 is pushed to move, and the third vacuum suction cup 801 with the cosmetic packaging bottle adsorbed thereon also moves, so that the third vacuum suction cup 801 with the cosmetic packaging bottle adsorbed thereon moves to the top of the conveyor belt 906, and the vacuum pump is turned off. The third vacuum suction cup 801 releases the cosmetic packaging bottle, and the cosmetic packaging bottle falls onto the conveyor belt 906. The second motor 910 drives the driving pulley 909 to rotate, and drives the driving pulley 907 to rotate under the driving action of the driving belt 908. The driving roller 904 also rotates, thereby driving the conveyor belt 906 to move, and the conveyor belt 906 drives the cosmetic packaging bottle to move for unloading, thereby realizing automatic unloading of the cosmetic packaging bottle.
