AI Technical Summary
Technical Problem
The electric cylinder guide shaft of existing 3D printing equipment is not effective in preventing dust in dusty and debris environments, which leads to increased operating resistance, wear and jamming, affecting printing accuracy and efficiency.
Method used
It adopts a multi-layer dustproof structure, including a dust cover, a skeleton oil seal and a wool felt ring, which isolates dust and debris layer by layer to prevent them from accumulating in the gap between the guide shaft and the linear bearing or copper sleeve.
Benefits of technology
It significantly improves dust prevention, reduces guide shaft wear, ensures smooth operation of the electric cylinder, enhances 3D printing accuracy and efficiency, and extends equipment lifespan.

Abstract
The utility model discloses a dustproof structure for 3D printing's electric cylinder guide shaft, including drive motor, drive motor one side is provided with drive cylinder, and the upper end fixed mounting of drive cylinder has the fixed plate, the upper end of fixed plate is provided with movable plate, and the middle part between fixed plate and movable plate forms printing chamber, the four around of fixed plate and movable plate and located printing chamber is provided with guide shaft. The design through dust cover, skeleton oil seal and wool felt ring etc. multilayer protective structure, to guide shaft has carried out multilayer dustproof, strengthens gradually, when electric cylinder produces metal dust accumulation condition in the working process, makes metal powder unable to accumulate in the clearance of guide shaft and linear bearing or copper bush, greatly improves the dustproof effect, reduces the abrasion of guide shaft and guide cylinder etc. component, thereby guarantees the smooth operation of electric cylinder, guarantees the precision and efficiency of 3D printing, prolongs the service life of equipment.
