Abstract: A vacuum packaging method and device are provided. The method comprises acquiring size information of a package and selecting a suction constant b; controlling a door to seal the vacuum chamber after the package is disposed into a vacuum chamber; actuating a vacuum pump set and starting timing, and respectively recording time nodes t1 and t2 when a pressure detected inside the vacuum chamber is lowered to a first preset pressure P1 and a second preset pressure P2; calculating time difference ?t by a formula ?t=t2?t1 based on t1 and t2; obtaining total suction time T or suction-stopping pressure P based on ?t and b; continuously performing suction by the vacuum pump set, and controlling the vacuum pump set to stop suction once a suction time reaches T or the pressure inside the vacuum chamber is lowered to P; controlling a heater to finish heat-sealing.

Abstract: The disclosure provides a smart heat sealing method for vacuum packaging, comprising steps of: recording a time interval ?t between two adjacent starts of a heating device which is continuously started a number of times; recording a number k of starts of the heating device; obtaining a first heating coefficient p1 based on ?t, obtaining a second heating coefficient p2 based on k, selecting the heating constant t depending on specified parameters and performance of the vacuum package machine, and calculating the heating time T for next operation of the heating device by a formula T=p1*p2*t based on p1, p2, and t. It solves the heat accumulation problem of the heating device caused by too much repeated use or overuse in short time interval, and thus avoids unsuccessful vacuuming and solves the problem of poor heat sealing effect, and greatly improves user experience.
