Description

Technical Field

[0001] This utility model relates to the technical field of food vacuum packaging, and in particular to a food vacuum packaging device. Background Technology

[0002] Vacuum packaging involves removing all the air from the packaging container and sealing it, maintaining a high-pressure state inside the bag. The scarcity of air is equivalent to a low-oxygen effect, which eliminates the conditions for microorganisms to survive, thus ensuring the freshness of food and preventing spoilage. Food that has undergone vacuum packaging can be transported over long distances and stored for extended periods.

[0003] Among existing food vacuum packaging devices, such as the one disclosed in utility model patent application number 202421059529.6, this utility model uses a vacuum pump to extract air from the vacuum chamber and the food packaging bag through a vacuum tube, so that the food packaging bag containing food is in a vacuum state. The clamping of the food packaging bag on the opposite sides by two flat plates makes the above-mentioned vacuuming process more stable. After the food packaging bag is flattened by the two flat plates, the sealing performance of the food packaging bag after being heat-sealed by the first heat-pressing strip is good, avoiding problems such as air leakage and material leakage, ensuring the effect of food packaging, and improving the safety of food consumption.

[0004] However, even after food is vacuum-packed, households still have a need to seal and preserve any food that has not been consumed after opening. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a food vacuum packaging device that, by setting up an air inlet mechanism and a vacuum mechanism, can re-vacuum seal food that has not been consumed in time during the food vacuum packaging process, thereby extending the food's shelf life.

[0006] This utility model provides a food vacuum packaging device, which includes two sets of pressing mechanisms; it also includes two sets of heat sealing mechanisms, four sets of limiting mechanisms, an air inlet mechanism, and a vacuum mechanism. Each set of pressing mechanisms is equipped with one set of heat sealing mechanisms, and each set of heat sealing mechanisms is equipped with two sets of limiting mechanisms. The air inlet mechanism is installed on the two sets of pressing mechanisms, and the vacuum mechanism is installed on the right end of one set of pressing mechanisms. The pressing mechanism performs pressing, the heat sealing mechanism performs sealing, the limiting mechanism performs limiting, the air intake mechanism allows air to enter, and the vacuum mechanism performs vacuuming. By using two sets of pressing mechanisms for pressing, opening the vacuum mechanism to perform vacuuming, using the air intake mechanism to facilitate air extraction, using the heat sealing mechanism to heat seal the packaging bag, and using the limiting mechanism to limit the heat sealing, food that has not been consumed in time can be resealed during the food vacuum packaging process, thus extending the food's shelf life.

[0007] Preferably, the pressing mechanism includes a housing and a toothed block, the toothed block is mounted on the housing, and the two housings are rotatably connected by a spring; the housing presses the packaging, and the toothed block facilitates ventilation.

[0008] Preferably, the heat sealing mechanism includes a movable box, two sets of springs, a heat insulation roller, and a heating strip. The movable box is slidably mounted on the outer shell by the two sets of springs, the heat insulation roller is rotatably mounted on the movable box, and the heating strip is mounted on the heat insulation roller. The heat insulation roller is brought into contact with the movable box by the springs, the heating strip is heated by energizing it, and the heat insulation roller is rotated by pulling out the packaging, so that the heating strip contacts the packaging for heat sealing.

[0009] Preferably, the limiting mechanism includes a screw block, a top block, and a second spring. The screw block is mounted on the heat insulation roller, and the top block is slidably mounted in the movable box by the second spring. The top block is supported by the second spring so that the top block, in conjunction with the screw block, limits the heat insulation roller to rotate only in one direction.

[0010] Preferably, the air intake mechanism includes an intake port and a duct. The intake port is rotatably mounted on the outer casing by a spiral spring, and the duct is mounted on the intake port and communicates with the intake port; air is drawn into the bag through the intake port.

[0011] Preferably, the vacuum mechanism includes a negative pressure chamber, a sludge collection box, and a vacuum pump. The negative pressure chamber is installed at the right end of the outer casing and is connected to 15 via a conduit. The sludge collection box is slidably installed inside the negative pressure chamber, and the vacuum pump is installed at the right end of the negative pressure chamber. By turning on the vacuum pump, the negative pressure inside the negative pressure chamber is vacuumed, and the sludge collection box collects and cleans the sucked-in impurities.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: pressing is performed by two sets of pressing mechanisms, vacuuming is performed by opening the vacuum mechanism, air is easily extracted by the air intake mechanism, the packaging bag is heat-sealed by the heat sealing mechanism, and the heat sealing mechanism is limited by the limiting mechanism. Thus, during the food vacuum packaging process, food that has not been consumed in time at home can be vacuum-sealed again, extending the food's consumption time. Attached Figure Description
