The invention relates to a double-station automatic bridle end sealing mechanism of a steel wire ring. The double-station automatic bridle end sealing mechanism consists of an air cylinder, swinging rods, a linking pin, a connecting rod, a clamp plate body, a reset spring, a reset rod, a cutter, a clamp plate, a clamp plate support frame and an air cylinder box, wherein a screw bolt hole is formed in the upper side of the air cylinder box and is connected with an external supporter; the air cylinder box and the air cylinder form a mechanism power source; the pneumatic device can push the air cylinder to do vertical and reciprocating movement; the air cylinder is connected with the clamp plate support frame; the support frame is driven to do ascending and descending movement; the swinging rods are arranged on the clamp plate support frame; the two swinging rods are connected onto the clamp plate support frame through the linking pin; meanwhile, the linking pin is connected with the reset rod; the reset spring is arranged on the reset rod; the lower side of the clamp plate support frame is fixedly connected with the cutter; the swinging rod is connected with the connecting rod through a pin; the connecting rod and the clamp plate are connected through a pin. The mechanism has the advantages that the ascending and descending of the clamp plate, and the closing of the clamp plate can be realized; the two-freedom movement can be realized; the simultaneous and automatic bridle end sealing can be automatically realized on two steel rings.

The invention discloses a demolding and packaging device for a rubber sealing ring. The demolding and packaging device for the rubber sealing ring comprises a forming unit, a separating unit, a moving unit, a demolding unit, a spraying unit and a packaging unit. The forming unit comprises an upper mold and a lower mold which mutually form a forming cavity; after the upper mold drives the formed rubber sealing ring to be separated from the lower mold under the action of the separating unit, the moving unit moves from the upper part of the lower mold to the upper part of the demolding unit, and the formed rubber sealing ring is separated from the upper mold under the action of the demolding unit; the spraying unit sprays an anti-aging lubricating agent to the demolded rubber sealing ring; and the packaging unit packages the rubber sealing ring sprayed with the lubricating agent.

The invention provides an underflow type passage mechanism for an alloy solution converter in the technical field of the alloy solution converter, and simultaneously relates to a method for alloy solution circulation control by using the underflow type passage mechanism for the alloy solution converter. The underflow type passage mechanism comprises a communication pipeline (3) used for communicating a smelting furnace (1) and a heat insulation furnace (2), wherein alloy solution (13) is set in a structure and can flow to the heat insulation furnace (2) from the smelting furnace (1) along the communication pipeline (3), an outer ring of the communication pipeline (3) is respectively provided with a heating device (4) and a cooling device (5), and the underflow type passage mechanism also comprises a control component (6) used for controlling the opening and the closing of the heating device (4) and the cooling device (5). The mechanism and the method provided by the invention have the advantages that the structure is simple, the dismounting and the assembly are convenient, the long-period contact of the alloy solution and the air can be avoided, the zinc oxidation is reduced, and the alloy solution quality is improved.
