[0050] Packaging heat sealing components include:

[0051] Thermoplastic pressure plates 9, both sides of which are installed between a group of positioning plates 10, and two thermoplastic pressure plates 9 are symmetrically arranged, and the heating surfaces of the two thermoplastic pressure plates 9 are arranged opposite to each other;

[0052] A push plate 12 is installed on one side of the thermoplastic pressure plate 9, and the push plate 12 and the thermoplastic pressure plate 9 form a T-shaped structure.

[0055] Working principle: when using the packaging machine with a feeding limit mechanism, the workbench 1 is installed above the logistics conveyor belt through the positioning frame 14, so that the workbench 1 is located below the funnel feeding of the material production to prepare for feeding. As the rectangular opening at the upper end of the workbench 1 cooperates with the limiting plate 2 to converge the two sides of the packaging bag, the packaging bag clamping plate 7 at the upper end of the positioning table 6 is cooperated to further limit the position of the two sides of the packaging bag to avoid excessive pulling and displacement of the packaging bag due to the weight of the material during the feeding process. The two thermoplastic pressure plates 9 located inside the positioning frame 14 are cooperated with the lifting column 13 and the auxiliary slide bar 11 to limit the bottom end of the packaging bag and thermoplastic seal. As the lifting column 13 and the auxiliary slide bar 11 are raised and lowered, the packaging bag capacity is adjusted, which is convenient for packaging and adjusting the limit of the material. The inclined surface of the positioning table 6 at the rectangular opening of the workbench 1 further limits the auxiliary packaging bag side plate, so that the device limits the feeding of materials into the packaging bag, thereby increasing the overall practicality.
