Background

Films made from polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins are used for packaging and as a film coating. With the rise of living standards and the pace of life increasing, people are increasingly buying processed foods, which are usually placed in containers (e.g., bowls) and protected from contamination by a film. When food is coated and packaged, the stacked bowls need to be separated one by one, and food materials are respectively put into the bowls for coating. The method for filling food materials into a container and coating a film in the prior art has the problems of more manual intervention, difficulty in ensuring cleanliness and the like.

The spiral separating mechanism on the market is only suitable for separating small-caliber containers (such as coffee cups) stacked together, and the gap between the adjacent containers is not too large, so that the spiral separating mechanism cannot be used for separating stacked bowls with large calibers and small bowl gaps (gaps between two adjacent bowls). The bowl stacking cam divider and the gear lifting mechanism have respective defects in the process of separating stacked bowls: the structure of the bowl stacking cam divider is complex to process, and needs to be combined with an external structure for storage indexing, so that the adjustment is not facilitated; the gear lifting mechanism can only separate stacked bowls with large bowl gaps.

s2, driving the stacked bowl 10 positioned at the driving station through the bowl lifting mechanism 2 to realize that the uppermost bowl of the stacked bowl 10 is positioned at the bowl grabbing position;

s3, driving the centering grabbing mechanism 3 to move to the position above the bowl grabbing position through the horizontal lifting mechanism 4, and grabbing the bowl at the bowl grabbing position by the centering grabbing mechanism 3; the centering grabbing mechanism 3 is driven by the horizontal lifting mechanism 4 to be above the food material containing mechanism 5; the centering grabbing mechanism 3 places the grabbed bowl on a second bowl supporting plate 54 of the food material containing mechanism 5; the centering grabbing mechanism 3 returns to the position above the bowl grabbing position;

the food containing mechanism 5 can be driven to be located below the food containing position through the second transverse sliding block in advance, then the centering grabbing mechanism 3 is driven to place a bowl, and the height of the second bowl supporting plate 54 can be adjusted through the third longitudinal sliding block 532 in the bowl placing process.

S4, driving the bowl placed on the food material containing mechanism 5 to a bowl placing position (the second longitudinal slide block 421 can be matched with the third longitudinal slide block 532), and filling food materials into the bowl;

s5, driving the food containing mechanism 5 to enable the bowl of the food containing mechanism 5 to be located at a film pressing position, enabling the film pressing ring 51 to be as high as the bowl edge, and laminating the film on the bowl through the film pressing mechanism 6;

s6, driving the food containing mechanism 5 to enable the bowl of the food containing mechanism 5 to be located at the bowl taking position.

The bowl position is shown in FIG. 1A. Also shown in fig. 1B is a food access door 7. The bowl at the bowl taking position is taken away by opening the food taking material door 7.

The bowl lifting, grabbing and film pressing mechanism 6 can automatically grab and separate stacked bowls 10, drive the grabbed bowls to the food material placing positions to facilitate food material placing, drive the bowls with food materials to the film pressing positions to automatically perform film covering, and automatically drive the bowls to the bowl taking positions after the film covering is finished. The invention realizes the full automation of food bowl packaging, film coating and packaging, improves the food processing sanitation, and prevents manual accidental contact and food material pollution. The invention has simple structure, is easy to realize and is not limited by the diameter of the stacked bowls 10 and the bowl gap.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and various equivalent modifications and substitutions can be easily made by those skilled in the art within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
