Background

The sealing mechanism of the packaging machine is a part of the packaging machine, and when the plastic film passes through the former to form a bag body, the bag body needs to be sealed through the sealing mechanism.

The bag body sealing mechanism comprises a longitudinal sealing mechanism and a transverse sealing mechanism, the longitudinal sealing mechanism is used for forming a vertical seal by using a pair of vertical heating blocks after being closed, the transverse sealing mechanism is used for forming a transverse seal by using a pair of transverse heating blocks after being closed, and a cutter stretches out and transversely cuts the plastic bag.

The prior art has the following disadvantages:

1: in order to avoid that the space of the transverse sealing part is reduced due to the opposite pressure of the bag in the transverse sealing process, only a certain length needs to be reserved at the transverse sealing part, and a part of air is reserved at the transverse sealing part, so that the vacuum packaging effect cannot be generated after the bag is formed;

2: because when liquid and paste sauce are filled into the plastic bag, the condition that part of sauce liquid is left in the plastic bag at the sealing position often occurs, under the condition, after the heat sealing modules at two sides clamp the plastic bag towards the middle, the position of the sauce is squeezed by the heat sealing modules, the plastic bag at the periphery can be sealed, but the sealing can not be performed at the position, and the sealing condition is unstable.
