[0057] In this scheme: an automatic sealing device for soup bag packaging, comprising the following steps:

[0058] During the process of sealing and packaging the soup bags, the soup bags to be sealed are pre-placed into the soup bag packaging box 102. After placement, the soup bag packaging box 102 is placed on the placement groove 104 of the supporting platform 103, and the soup bag packaging box 102 is positioned and placed. After the soup bag packaging box 102 is positioned and placed, the entire supporting platform 103 is pushed into the sealing and packaging machine 101 by moving the components. During the pushing process, the soup bag packaging box 102 is placed below the heat sealing plate 105.

[0059] After the soup bag packaging box 102 is positioned and pushed in, the driving assembly is used to drive the heat-sealing pressing plate 105 to move downward. During the downward movement of the heat-sealing pressing plate 105, the connecting action of the first spring 803 on each group of T-bars 802 drives the circular pressing plate 801 to move downward. During the downward movement of the circular pressing plate 801, the circular pressing plate 801 first abuts against the sealing bag 303 and pushes the sealing bag 303 against the supporting platform 103. Through the abutment between the circular pressing plate 801 and the sealing bag 303, the sealing bag 303 to be sealed is pre-pressed against the supporting platform 103 to avoid the sealing bag 303 from being pressed against the supporting platform 103 during the sealing process. 03 moves to affect the sealing effect. After the sealing bag 303 is pushed to press against the supporting platform 103, the heat-sealing plate 105 is driven to move downward. During the downward movement of the heat-sealing plate 105, the pressed sealing bag 303 is pushed to press against the upper end of the soup bag packaging box 102. Through the pressing effect and the heat-sealing effect of the heat-sealing plate 105, the soup bag packaging box 102 is sealed and packaged. In the process of the circular pressing plate 801 descending and pressing against the sealing bag 303, since the lower end of the expansion plate 903 is below the circular pressing plate 801, the expansion plate 903 First, it abuts against the sealing bag 303. During the abutment process, as the circular pressure plate 801 continues to descend, the sealing bag 303 and the expansion plate 903 are abutted against each other to push the expansion plate 903 toward the inside of the installation slot 901 for contraction movement. During the contraction movement of the expansion plate 903, the strip plate 902, the slider 1102 and the transmission pin 1201 on the slider 1102 are driven to move synchronously. During the movement of the transmission pin 1201, the transmission pin 1201 and the inclined surface 1203 on the transmission plate 1202 abut against each other to drive the slider 1102 to move under force. During the movement of the slider 1102, The sliding guide function of the multiple groups of guide rods 1104 causes the slider 1102 to move toward the outside of the circular pressing plate 801 after being stressed. During the movement of the slider 1102, the unfolding plate 903 shrinks toward the inside of the mounting groove 901 and simultaneously moves toward the outside of the circular pressing plate 801. Since the unfolding plate 903 abuts against the upper end of the sealing bag 303, the unfolding plates 903 on each group of flattening components move toward the outside of the circular pressing plate 801, and the abutting sealing bags 303 are pulled and flattened, thereby preventing the wrinkles on the sealing bag 303 from affecting the sealing and packaging process of the soup bag packaging box 102, thereby ensuring the packaging quality of the soup bags.

[0060] After the soup bag packaging box 102 is sealed and packaged, the heat-sealing pressure plate 105 is reset and the supporting platform 103 is pulled out, and the sealed soup bag packaging box 102 is taken out. After the sealing process, the two sets of driving motors 304 drive the receiving roller 301 and the discharging roller 302 to rotate and transport the sealing bag 303. The transportation of the sealing bag 303 facilitates switching to different positions for sealing. In the process of conveying the sealing bag 303, the elastic component is used to push the extrusion plate 502 on the mounting plate 501 to keep it against the outside of the sealing bag 303, so as to generate pressure on the sealing bag 303, so that the sealing bag 303 is always in a taut state during the transportation process, so that the sealing bag 303 can be more stably transported and sealed.
