[0042] Lay the wide long roll material between the adsorption platform 2 and the dispensing mechanism 4. The adsorption platform 2 adsorbs the long roll material on the adsorption platform 2. The cross-section between the abutment surface 37 and the support surface 38 in the lifting module 3 cooperates to convert the horizontal driving force into the driving force in the vertical direction, lift the adsorption platform 2, and move the adsorption platform 2 toward the dispensing mechanism 4. According to the preset dispensing path, the two dispensing mechanisms 4 perform synchronous dispensing of the long roll material on the adsorption platform 2 in different areas: the Y-direction auxiliary adjustment component 42 controls the movement of the crossbeam 6 to make the two dispensing mechanisms 4 move synchronously along the Y-axis direction; the Y-direction auxiliary adjustment component 42 controls the two dispensing mechanisms 4 to move separately along the Y-axis direction according to the changes in their respective dispensing paths; the X-direction drive component 52 controls the two dispensing mechanisms 4 to move separately along the X-axis direction according to the changes in their respective dispensing paths; the lateral auxiliary adjustment component controls the movement of the crossbeam 6 to make the two dispensing mechanisms 4 move synchronously along the X-axis direction.

[0043] On the one hand, the present application converts the horizontal driving force into the vertical driving force through the mutual cooperation between the active block 31 and the abutting surface 37 on the driven block 32, thereby replacing the existing lifting devices such as cylinders, achieving a larger output while saving installation space, and adsorbing large workpieces on the adsorption platform 2 to realize the lifting operation of large workpieces.
