[0002] Paper jars, also known as paper tubes or paper cans, are listed under the national standard GB\T10440-2008. They are round packaging products that combine metal, paper, and plastic, and are typically available in spiral and rewindable styles. Made primarily of paper, paper jars are easily recyclable. They offer excellent protection, are waterproof and moisture-proof, and offer a certain degree of thermal insulation. They are odorless, non-toxic, and safe, making them particularly suitable for food packaging. They are quiet during filling, and can be color-printed for excellent display. Their lightweight, only 30% of that of an iron can, makes them easy to distribute, convenient to use, and affordable. Composite paper jars have a wide range of applications and are commonly used to package powdered solid foods such as cocoa, tea, sugar, salt, cereal, coffee, and various solid beverages. They represent a new generation of environmentally friendly packaging, offering a viable alternative to glass, ceramic, and other packaging materials. Composite paper cans are also a new type of packaging product. They are not only green and environmentally friendly, but also have low manufacturing costs. They are a good choice for food packaging. They combine paper, film and iron into one, and are the best container for fresh-keeping food packaging. They have the advantages of superior sealing performance, safety and hygiene, low cost, and novelty and fashion.

[0090] The pressing and limiting module 54 includes a movable limiting plate 541, a limiting tray 542, and a limiting lifting power source 543. The movable limiting plate 541 is positioned vertically opposite the pressing block 53 and is movably disposed below the accommodating mold 22. The limiting tray 542 is fixedly mounted on top of the movable limiting plate 541. The limiting lifting power source 543 is fixedly mounted on top of the equipment frame 1. The bottom of the movable limiting plate 541 is fixedly connected to the movable portion of the limiting lifting power source 543.

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

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

[0093] S1: The cylindrical paper can without a film installed is placed on the receiving mold 22 by automated equipment. Specifically, the bottom end of the cylindrical paper can passes through the inner hole of the limiting ring 23 and is set in the supporting 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 support turntable 2 to rotate circumferentially so that the accommodating mold 22 moves to the top of the rotating support plate 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 and enters the cylindrical paper can;

[0096] S4: The second power source 313 drives the driving gear 312 to engage 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 return to its original position and drives 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 transfer groove 431-3.

[0098] S6, the transfer power source 422 drives the flip arm 421 to rotate toward the film temporary storage assembly 41, so that the suction assembly 423 flips to the extraction position to suck the film 6. At the same time, the separation assembly 424 blows air into the extraction position to separate the unsucked film from the sucked film, preventing the unsucked film from being carried 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. The transfer power source 422 drives the flip arm 421 to flip toward the first receiving position 431-1, so that the flip arm 421 passes through the avoidance strip groove 432-2 and the avoidance through hole 432-1 to absorb the film on the suction assembly 423 and place it in the film receiving position 435. When the film is in 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 translational power source 433 drives the movable receiving plate 432 to move to the second receiving position 431-2. 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 pick-up and placement 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. The pick-up and placement 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. Then, the movable receiving plate 432 returns to the first receiving position 431-1 to wait for the next work. At the same time, the flip arm 421 returns to the extraction position.

[0102] S10: The pick-up and place lifting power source 442 drives the movable support bar 443 to move vertically downward, so that the film passes through the material channel 431-3 and enters 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, driving the negative pressure suction cup 444 to be tilted, so that the film is tilted and placed into 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 return to its original position, so that the negative pressure suction cup 444 returns 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 support turntable 2 to rotate circumferentially so that the accommodating mold 22 moves 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 contacts 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 top of the limiting tray 542 is set at a height lower than or flush with the bonding portion.

[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 adhere to the adhesive portion. At this time, the bottom film is supported by the limiting tray 542 to prevent the middle of the bottom film from denting, which would affect the firmness and aesthetics of the adhesion.

[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 accommodating mold 22 away from the pressing device 5. The cylindrical paper can with the film installed is removed from the accommodating mold 22 and collected through automated equipment.

[0107] Compared with the existing technology, this 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 shape under the action of the lifting module. Compared with the bottom film being placed in the cylindrical paper can in a horizontal state, it has the advantages of small shape deformation and no squeezing with the inner circumference of the cylindrical paper can.

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