The invention relates to a punching machine with a suction cup feeding structure for glass bottle cap manufacturing, and belongs to the technical field of glass bottle cap machining equipment.The punching machine with the suction cup feeding structure for glass bottle cap manufacturing comprises a base, a mounting frame is arranged at the top of the base, and a rotating roller is arranged in the mounting frame; a mounting frame is arranged on one side of the base, a vacuum suction cup mechanism is arranged in the mounting frame, a lifting assembly is arranged on one side of the base, and the lifting assembly comprises a bottom plate arranged on one side of the base, in the invention, stacked plates are placed on a top plate, a hydraulic cylinder is started to enable a round rod of a shear type connecting rod to slide along the bottom plate, the connecting rod rotates to drive the top plate to ascend, and a vacuum suction cup sucks up a single plate; after being conveyed by the rotating roller and leveled by the upper roller shaft and the lower roller shaft, the sheet metal falls to the punching machine along the third baffle, the sensing device monitors the height of the sheet metal in real time, the hydraulic cylinder is controlled to lift the top plate along with consumption of the sheet metal, deformation wrinkles caused by height reduction caused by consumption of the sheet metal in the feeding process are solved, and therefore the feeding stability is guaranteed.

The utility model provides a supporting structure for excavation of a foundation pit, and relates to the technical field of supporting structures, the supporting structure comprises a supporting frame arranged close to the wall of the foundation pit, the supporting frame is composed of a lower supporting seat, a supporting main body and an upper supporting seat, and the supporting main body is arranged between the lower supporting seat and the upper supporting seat; inserting rods are arranged at the positions, close to the corners, of the bottom of the lower supporting base. Based on a supporting structure in the prior art, the designed supporting structure provides supporting stable fulcrums for supporting in the prior art, an inserting rod is designed at the bottom of a lower supporting base and is stably inserted into the ground, stand columns and supports are arranged in a staggered mode, connecting rods are added to serve as the fulcrums, and the stand columns (or inclined struts can abut against and be installed on the parts) are arranged. And the connection design and other modes of the upper supporting seat are matched with the supporting structure on the side wall of the same side for matched connection, pressure is conducted and dispersed, then the supporting stability is guaranteed, and the problem that the supporting column inclines and collapses due to insufficient supporting force of the supporting point is solved.

The utility model discloses a lining type sealing rubber ring which comprises a ring body, a shaping ring, a baffle ring, a pressing ring and a positioning ring. The ring body is placed at the butt joint port of the pipeline in a lining mode, then the ring body is pushed into the butt joint port of the pipeline, at the moment, the positioning ring can be compressed under stress and clamped in the pipeline, the ring body is positioned in the pipeline, the ring body is effectively prevented from inclining and collapsing, and the butt joint pipeline can be in contact with the protruding part of the pressing ring when the pipeline is in butt joint. Due to the fact that the contact face of the protruding part is small, the ring body is not prone to being driven to rotate when the butt-joint pipeline is subjected to bolt hole correction and rotates, the ring body is prevented from being twisted and deformed when the pipeline is corrected, the pipeline can extrude the pressing ring and the ring body after being subjected to butt joint, and the pressing ring and the ring body are sealed at the butt-joint position of the pipeline.

The present application relates to a kind of finished grain stacking system, including stacking group, each stacking group includes at least two stacking series, each stacking series includes at least two stacking components, stacking component includes the stacking cage with the cage fork hole being provided at bottom, stacking cage includes cage bottom plate and the three lateral cage side limit being arranged on the upper end of cage bottom plate, define the two stacking cages adjacent in upper and lower direction in the same stacking component as upper side stacking cage and lower side stacking cage, the bottom four corners of upper side stacking cage are connected with the top four corners of lower side stacking cage by the positioning structure of concave-convex positioning cooperation along the upper and lower direction, stacking component further includes the tray for being placed on the upper side of cage bottom plate, tray bottom is provided with tray fork hole, and finished bagged grain is stacked between the upper side of tray and each cage side limit, the present application solves the technical problem that the lowermost packaging bag is easily damaged under greater pressure in the prior art, and the stacking structure is unstable and easily inclined to collapse.
