AI Technical Summary
Traditional lifting cylinders cannot be installed or small lifting cylinders that are not vertically mounted have insufficient lifting height, which cannot meet the needs of fully automated loading and unloading of parts in modern machining, especially in silos with limited space and insufficient product load capacity.
The double-stroke lifting mechanism, which uses a worm gear assembly and a double rack and pinion assembly, achieves double the lifting height by driving the lifting plate and the coordinated movement of the gears and racks through a stepper motor. Combined with the cooperation of guide bearings, guide shafts, sliders, slide rails and guide columns, it ensures stability and load-bearing capacity.
It achieves a higher lifting effect in a limited space, increases the product load capacity, is suitable for a variety of equipment in confined spaces, and has a simple structure and low cost, thus improving the efficiency of automated loading and unloading.
