The utility model belongs to the technical field of sample pneumatic pipeline conveying and pneumatic sample conveying in the
metallurgical industry, and particularly relates to a pressing type sample
barrel cover opener. Comprising a
machine table, a horizontal telescopic mechanism, a vertical telescopic mechanism, a cover opening mechanism, a
barrel clamping mechanism and a cover placing mechanism. In the working process, a
robot places a sample
barrel on the
machine table, the barrel clamping mechanism clamps the sample barrel, the horizontal telescopic mechanism adjusts the horizontal displacement of the uncovering mechanism, and the vertical telescopic mechanism adjusts the
vertical displacement of the uncovering mechanism and is matched with the uncovering mechanism to pull out a sample barrel cover and place the sample barrel cover temporarily. According to the scheme, cover opening and cover placing of the pressing type sample barrel are automatically completed, full-automatic work is achieved in cooperation with a
robot, labor is saved, and the working efficiency is improved. And meanwhile, the cover
opening action and the cover placing action are completed through cooperation of the cover opening mechanism, the vertical telescopic mechanism and the horizontal telescopic mechanism, additional parts are not needed, the structure is simple, the number of quick-wear parts is small, and the equipment maintenance cost is saved.
