Description

Technical Field

[0001] The utility model relates to the technical field of food vacuum packaging machines, in particular to an automatic vacuum packaging machine for slightly fermented salted egg products. Background Art

[0002] Micro-fermented preserved eggs are preserved eggs that have been fermented with microorganisms and salted. They are a new type of preserved egg product with a unique flavor and are highly sought after by consumers. After production, the micro-fermented preserved eggs are vacuum-packed and then sterilized at high temperatures to ensure long-term storage and convenient purchase.

[0003] The double-chamber vacuum packaging machine is a commonly used automatic food packaging machine. The two vacuum chambers can respectively place slightly fermented salted eggs packed in packaging bags. While placing them on one side, the other side automatically draws a vacuum through the vacuum sealing cover and automatically seals with the heat sealing strip. It is very convenient to use.

[0004] Egg products, including slightly fermented salted eggs, share a common characteristic: most customers are concerned about the integrity of the eggshell. A damaged shell can easily cause the egg white to leak out during packaging and subsequent transportation, affecting the product's appearance and, consequently, sales. Therefore, due to the rigid stainless steel bottom plates of existing dual-chamber automatic vacuum packaging machines, particular care must be taken when placing and handling the slightly fermented salted eggs. Otherwise, accidentally breaking the shell can severely limit and impact packaging efficiency, presenting a significant challenge. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the utility model provides an automatic vacuum packaging machine for slightly fermented salted eggs, which is used to solve the problem that the bottom plates of the vacuum chambers of the existing double-chamber automatic vacuum packaging machines are all rigid stainless steel, which easily breaks the eggshells when packaging slightly fermented salted eggs.

[0008] Preferably, the bottom of the inner wall of the vacuum chamber is a smooth stainless steel plate.

[0009] Preferably, the lower surface of the positioning pad is evenly provided with curved adsorption grooves, and the positioning pad is adhered to the bottom of the inner wall of the vacuum chamber through the adsorption grooves.

[0010] Preferably, the positioning pad and the fixed support block are an integrated elastic rubber structure or an integrated elastic silicone structure.

[0011] Preferably, the elastic rubber bands are parallel to each other.

[0012] Preferably, the connection points of the elastic rubber band and the fixed support block are located on the same downwardly curved arc.

[0013] Preferably, a through hole is provided on the movable support block at a position corresponding to the elastic rubber band.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model places a positioning pad at a position corresponding to a heat-sealing strip in a vacuum chamber, presses the positioning pad to discharge air through an adsorption groove at the bottom and sticks it to the vacuum chamber; before packaging, the spacing between two adjacent movable support blocks and between the movable support block and the fixed support block are adjusted laterally according to the different sizes of the raw materials of the micro-fermented salt-and-peel eggs, such as chicken eggs, duck eggs and goose eggs, so as to adapt to the sizes of different batches of micro-fermented salt-and-peel eggs; the elastic rubber band is supported by the fixed support block and the movable support block, and the micro-fermented salt-and-peel eggs are elastically supported by the positioning pad and the elastic rubber band, thereby effectively achieving a buffering effect during vacuum packaging of the micro-fermented salt-and-peel eggs, greatly reducing the probability of the micro-fermented salt-and-peel egg shells being broken, making it more convenient for staff to operate, effectively improving the packaging efficiency, and solving the problem that the bottom plates of the vacuum chambers of existing double-chamber automatic vacuum packaging machines are all rigid stainless steel and are prone to breaking egg shells during packaging of micro-fermented salt-and-peel eggs.
