The lifting air cylinder 233 is started again to cooperate with the operator to operate the vacuum suction nozzle into the bag opening for vacuum extraction. At this time, the heat sealing chuck on the sealing head 11 loads the surface of the bag opening. In the process of vacuum extraction, the slow descending air cylinder 13 abuts against the sealing head 11. When the sealing head 11 descends by gravity, the slow descending air cylinder 13 reduces the descending speed of the sealing head 11. When the sealing head 11 abuts against the surface of the product during the descending process, the slow descending air cylinder stops descending under the action of the slow descending air cylinder, thereby ensuring that the product will not extrude the outer packaging bag to cause damage to the packaging bag. After vacuum extraction, heat sealing is performed. After heat sealing is completed, the sealing process is completed.

[0033] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be understood as within the protection scope of the present application.
