This realizes the precise matching of material filling and sealing positions, effectively improves packaging accuracy, and ensures the consistency of packaging quality.

[0039] This device employs a dual-station collaborative sealing mechanism to achieve efficient packaging operations. Its working principle is as follows: After material filling is completed, the control system drives the conveying mechanism to precisely position the material-packaging bag assembly at the fixed sealing module 7 station. Simultaneously, the fixed sealing module 7 initiates the heat-sealing operation, while subsequent materials synchronously fall to the working area of ​​the movable sealing module 6. This module completes the sealing and cutting process by maintaining synchronized descent with the materials through a sliding pair mechanism. The two modules achieve complete overlap in their operation times through synchronous programming of the motion control system, forming a continuous production cycle. This design significantly improves packaging efficiency through a spatiotemporal coupling operation method, and the coordination between modules ensures synchronization accuracy through real-time feedback adjustment.

[0040] The specific working principle is as follows: By installing a dual-station collaborative system of movable sealing module 6 and fixed sealing module 7, the spatiotemporal coupling of the material packaging process is realized. The system uses an electrically controlled drive mechanism to make the movable module move synchronously with the falling material to complete the sealing and cutting at the upper station. At the same time, the fixed module performs the sealing operation at the lower station, so that the operation time of the two modules completely overlaps, achieving the efficiency of completing double packaging in a single cycle, which significantly improves packaging efficiency. The cooperation of shock absorption and limit mechanism ensures the synchronous accuracy of module movement, solving the problem of intermittent downtime caused by alternating processes in traditional equipment. By integrating the drive and intelligent control component 63, the intelligent and high-precision control of the sealing process is realized. This component adopts a planar four-bar motion transmission system. Through the synergistic action of the power transmission link 631 and the limit force transmission link 633, the linear output of the electrically controlled telescopic rod 611 is converted into the precise vertical movement of the movable sealing module 6. With the help of the stroke limit block 632, the action boundary control is realized to ensure the repeatability of the sealing position.
