Technical Field
The invention belongs to the technical field of raw material packaging at the rear end of a food and medicine packaging machine, and particularly relates to a vacuum sealing mechanism and an areca nut packaging machine comprising the same.
Background
In the industrial production of betel nuts, the sealing operation process of the existing vacuum sealing machine is basically as follows: firstly, manually placing a packaging bag filled with betel nuts to a preset position according to specified requirements, namely ensuring that one end of the packaging bag needing to be sealed is just positioned on a heat sealing position of a sealing device, then closing a vacuum sealed chamber, starting the sealing device for heat sealing after vacuum extraction is finished, releasing pressure after heat sealing is finished, and manually taking out the sealed packaged betel nuts. Such vacuum sealing has several disadvantages: 1. the to-be-sealed package needs to be placed and positioned according to the specified requirements and manually taken and placed, so that time and efficiency are wasted, and potential safety hazards of workers are caused; 2. because the work flow is vacuum pumping first and then heat sealing, the packaging bag is easy to deform in the vacuum pumping process, thereby influencing the subsequent heat sealing effect, and because the appearance of the packaging bag after vacuum pumping is uncontrollable, the packaging attractiveness is influenced.
