This design facilitates process personnel to quickly adjust the packaging equipment and meets the packaging requirements of workpieces of different heights.

[0026] Please refer to Figures 1 to 4In this embodiment, the lifting assembly 13 includes a supporting platform 131, a screw shaft 132, a transmission sprocket 133 and a screw slide 134.

Through the transmission connection between the drive motor 12 and the transmission sprocket 133, and the cooperation between the screw shaft 132 and the screw slide 134, precise control of the up and down movement of the support wall is achieved; not only that, the drive motor 12 can synchronously control all the screw slides 134 to rise and fall to the same precise height through the cooperation of the chain and the transmission sprocket 133, avoiding the tilting phenomenon during the lifting of the entire sealing knife holder mechanism 5.

[0027] Please refer to Figures 1 to 4 In this embodiment, the lifting assembly 13 also includes a support bearing 136 and an axis end fixing member 137.

The existence of the second tensioning sprocket 16 can ensure that the chain maintains an appropriate tension state during the transmission process, thereby avoiding the transmission instability caused by loose or over-tightened chains, and reducing the vibration and impact of the chain during the transmission process, reducing the wear and fatigue of the chain, and thus extending its service life.

[0030] Please refer to Figures 1 to 4 In this embodiment, the lifting assembly 13 further includes an L-shaped fixing member 135, the long side of the L-shaped fixing member 135 is fixedly arranged on the surface of the lifting wall 14, and the screw slide 134 is installed on the bottom surface of the short side of the L-shaped fixing member 135. The long side of the L-shaped fixing member 135 is directly connected to the surface of the lifting wall 14, and the lifting force of the screw slide 134 can be directly transmitted to the lifting wall 14, thereby avoiding energy loss and reduced precision caused by a too long force transmission path.
