A packaging machine that can discharge the air in the bag and improve work efficiency

Abstract

The invention relates to the technical field of packaging-related equipment, and discloses a packaging machine capable of discharging air in a bag and improving work efficiency. Device and fixed rod, driving device is installed with heating device through the movable of electric telescopic rod, fixed rod right side is fixedly installed with blowing device, and blowing device inside is fixedly installed with air blower, air supply pipe and, heating ring. The packaging machine can discharge the air in the bag and improve the working efficiency. The driving device drives the electric telescopic rod, the heating device and the sliding rod to run. The sliding rod and the sliding rail cooperate to drive the No. 1 switch and the No. 2 switch to run, and drive the blower and the heating ring to work. , so that the hot air is ejected from the nozzle, and when the No. 2 switch is turned off, only the cold air is discharged, and the air flow squeezes the air inside the packaging bag, thereby achieving the effect of discharging the air inside the packaging bag, preheating the sealing part before processing, and cooling down after processing.

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.
