Packing machine capable of exhausting air in bags and improving working efficiency

Abstract

The invention relates to the technical field of packing related equipment, and discloses a packing machine capable of exhausting air in bags and improving the working efficiency. The packing machine comprises a shell; packing devices are fixedly mounted on the left and right sides of the inner wall of the shell; the packing devices comprise driving devices and fixed rods; the driving devices are movably provided with heating devices through electric extension rods; air blowing devices are fixedly mounted on the right sides of the fixed rods; and air suppliers, air supply pipes and heating rings are fixedly mounted in the air blowing devices. In the packing machine capable of exhausting the air in the bags and improving the working efficiency, the driving devices drive the electric extension rods, the heating devices and slide rods to operate; the slide rods and slide rails are matched to drive first switches and second switches to operate and to drive the air suppliers and the heatingrings to work, so that hot air is sprayed out from nozzles; the second switches are turned off to only exhaust cold air; and the air in packing bags is extruded by air currents, so that the air in thepacking bags is exhausted, seals are preheated before machining, and the cooling effect is achieved after machining.

Description

technical field [0001] The invention relates to the technical field of packaging-related equipment, in particular to a packaging machine capable of discharging air in a bag and improving work efficiency. Background technique [0002] The packaging machine is a mechanical device that seals the container filled with packaging. After the product is loaded into the packaging container, in order to keep the product sealed and stored, avoid product loss, and maintain product quality, it is necessary to seal the packaging container. This operation is Done on the packaging machine. [0003] In order to ensure the normal packaging of the machine, a part of space will be reserved on the upper part of the packaging bag, which contains a large amount of air. If it is not discharged, the air will remain inside the packaging bag after packaging, which may cause a crush explosion during transportation. Accidents, the existing vacuum pumping equipment has a complex structure, has requireme...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a packaging machine that can discharge the air in the bag and improve the working efficiency. The advantage of some residual air in the bag solves the problem that the existing packaging equipment cannot discharge the air in the packaging bag, the seal cannot be preheated before packaging, and the packaging bag needs to be allowed to stand for a period of time after packaging.
