Rolling vacuum body-fitted shaping packaging machine

Abstract

The invention provides a rolling vacuum body-fitted shaping packaging machine, and belongs to the technical field of mechanical packaging equipment. The problem that a packaging bag with gaps inside is prone to breakage due to the fact that the bag face of an existing packaging bag cannot be effectively attached to the surface of a product in the air exhaust process is solved. The rolling vacuum body-fitted shaping packaging machine comprises a box body, a mounting plate, a conveying device and a heat sealing device, wherein the heat sealing device comprises a vacuum plate, a vacuum pipeline,a hot melting plate and a heat sealing rod, the interior of the vacuum plate is of a cavity structure to form a vacuum chamber, the vacuum pipeline is located at the top of the vacuum plate and communicates with the vacuum chamber, and the hot melting plate is fixed into the vacuum plate through screws; a panel of the hot melting plate is provided with a plurality of rows of vertically-through airholes, a heat pipe is installed in the hot melting plate to achieve heat transfer, and the heat sealing rod is located behind the hot melting plate and fixed in the vacuum plate through adjusting knobs arranged at the two ends of the heat sealing rod. The packaging bag provided by the invention has the advantages that the packaging bag can be better attached to the surface of a product, and the sealing performance of the bag opening is better.

Description

technical field [0001] The invention belongs to the technical field of mechanical packaging equipment, and relates to a vacuum packaging machine, in particular to a rolling vacuum skin-fitting shaping packaging machine. Background technique [0002] The main function of the vacuum packaging machine is to remove the air in the packaging bag, so that the microorganisms are inhibited and stop breeding, which is beneficial to prevent product deterioration. The existing vacuum packaging machines directly pump out the gas in the vacuum chamber of the equipment through the vacuum pump, and then clean the bag mouth. Heat sealing, so it is easy to puncture the packaging bag for some products with sharp edges and corners, and when the product has high hardness and irregular shape, the bag surface cannot effectively fit the product surface during the pumping process, making There are voids inside, the packaging bag is easy to break, and the appearance is not beautiful enough.
