Technical Field
[0001] This utility model relates to the field of easy-open can production technology, and in particular to a film wrapping machine for easy-open can lid packaging. Background Technology
[0002] Easy-open can production technology and film-wrapping machines play a vital role in the food and beverage industry. With consumers' growing demand for convenient, safe, and aesthetically pleasing packaging, film-wrapping technology has become a key element in improving production efficiency, ensuring product hygiene and safety, and showcasing brand image. This equipment prevents external contamination and provides protection by wrapping the can lid with film material, while ensuring the packaging's airtightness and display effect. As the industry focuses on environmental protection and sustainability, manufacturers are beginning to explore the use of biodegradable materials to reduce environmental impact. The automation and intelligent development of film-wrapping machines further enhances production efficiency and packaging quality, and has broad development potential in the future application of environmental protection and intelligent technologies.

[0046] The finished product conveying assembly includes a first motor 21 fixed to the bottom inner side of the outer bracket 1. The first motor 21 is supported and fixed by the outer bracket 1. Multiple guide wheels 23 are rotatably connected to the inner side of the inner bracket 2. The guide wheels 23 are supported and limited by the inner bracket 2. The output end of the first motor 21 is fixedly connected to the end of the guide wheel 23 that is simultaneously away from the unwinding wheel 4 and the winding wheel 41.

[0047] Specifically, this easy-open can lid packaging film wrapping machine operates as follows:
[0048] The first air spring 13 and the mechanical claw 14 are moved laterally by the moving module 12. First, the mechanical claw 14 grabs the stacked easy-open can lids. Then, the first air spring 13 and the mechanical claw 14 are moved towards the winding wheel 41 by the moving module 12. After the mechanical claw 14 moves to the middle of the packaging film cleaning assembly, the first air spring 13 moves the mechanical claw 14 to the bottom and presses the packaging film until the easy-open can lid moves below the second heat sealing knife 34 and the first heat sealing knife 32.
[0049] During the pressing process of the easy-open can lid on the packaging film, the unwinding roller 4 releases the packaging film. When the packaging film passes the bottom of the cleaning port 51, the second motor 53 first drives the drive gear 54 and the cleaning roller 57 to rotate, thereby cleaning the impurities on the surface of the packaging film. At the same time, the exhaust fan 513 draws air from the filter box 5 through the filter screen 59, and draws external air through the cleaning port 51 to replenish the air inside the filter box 5. The air entering the filter box 5 blows up the cleaned impurities, and then filters the air carrying impurities through the filter screen 59. The air passes through the filter screen 59 and is transported through the sealed box 512 and the exhaust pipe 511 into the external exhaust gas treatment equipment.
[0050] While the drive gear 54 drives the cleaning roller 57 to rotate, the drive gear 55 drives the driven gear 56 to rotate synchronously. The driven gear 56 drives the cleaning impeller 58 to rotate on the outside of the filter screen 59, thereby cleaning the impeller 58 and pushing the impeller 58 to the drain pipe 510. The impeller 58 then transports the impeller into the external collection device.
[0051] The second air spring 3 drives the sliding frame 33 to slide on the outer wall of the inner support 2, and the sliding frame 33 drives the second heat sealing knife 34 to move towards the first heat sealing knife 32. Then, the second heat sealing knife 34 and the first heat sealing knife 32 cooperate to heat seal the packaging film wrapped on the outside of the easy-open can lid.
[0052] After being heat-sealed, the finished product falls onto the support rod 24 for collection. At the same time, the first motor 21 drives the transmission chain 22 to rotate, which in turn drives the support rod 24 to rotate, thereby conveying the finished product out.
[0053] After heat sealing on one side, the stretched packaging film is tightened by the winding roller 41, and the used packaging film substrate is wound up. Then, the easy-open can lid is put into the feeding assembly for continuous packaging.
[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
