Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an improvement on the feeding mechanism of a plastic sealing film packaging machine. Background Technology

[0002] To improve packaging efficiency, existing fully automatic packaging machines include a conveyor belt for transporting the packaged goods, a lifting mechanism at the end of the conveyor belt, a discharge platform for discharging the goods to the subsequent sealing station, and a pushing mechanism that matches the height of the discharge platform. However, existing models use a fixed-size design for both the lifting mechanism and the discharge platform, making it difficult to adapt to changes in the size, specifications, and structure of the packaged goods.

[0003] However, during the actual trial production process, it was discovered that the items to be packaged shifted when they were sent to the unloading table and moved upwards on the pallet inserter, thus affecting subsequent processes. Therefore, the applicant made further improvements based on the original application to eliminate this technical defect. Summary of the Invention

[0004] To address the above problems, this utility model provides a method that can adjust the axial dimension of the discharge platform, thereby changing the axial dimension of the top support platform of the lifting mechanism to accommodate packaging materials of different sizes.
