Automatic change gumming gloves along with trend tilting mechanism
Technical Field
The utility model relates to a tilting mechanism, in particular to change gumming gloves along with trend tilting mechanism.
Background
The technological process of producing labour protection gloves includes mainly the steps of preheating, soaking, primary stoving, desalting, soaking, secondary stoving and sulfurizing, and the soaking step includes soaking with impermeable agent, soaking with rubber and non-slip soaking with salt.
In the known continuous production line of labor gloves, the dipping driving scheme of the gloves comprises two types:
(1) passive dipping, for example, the gloves sequentially pass through a chain type conveying line and temporarily stay at corresponding working sections of a dipping procedure, namely an anti-seepage agent pool and a rubber pool in the dipping procedure, the anti-seepage agent pool and the rubber pool actively rise to enable the gloves to be in contact with materials in the anti-seepage agent pool and the rubber pool, and the gloves actively descend after being dipped so as to pass through the gloves smoothly; in the mode, because the volume of the anti-seepage agent tank and the rubber tank is large and the weight of the rubber tank is heavy, frequent lifting causes large energy consumption and high failure rate, and certain potential safety hazards exist.
(2) Active upset flooding, this kind of scheme is comparatively advanced, and when the mould pole passed through the flooding workshop section, the mould pole was driven by special mechanism and was rotated for the hand former upset on the mould pole contacts with the liquid in the flooding pond.
The structure generally comprises:
the clutch mechanism is used for disconnecting or connecting torque transmission between the die rod and the chain conveying line;
and the overturning driving mechanism is used for driving the mold rod to overturn around the rotatable structure.
When the mold rod normally moves, the clutch mechanism locks the connection between the mold rod and the chain conveying line, and the mold rod is fixed relative to the chain conveying line; and after the mold rod moves to the dipping station, the clutch mechanism is disengaged, and the mold rod is driven by the overturning driving mechanism to rotate on the chain conveying line, so that overturning dipping is realized.
The existing clutch mechanism and the overturning driving mechanism can realize automatic overturning and dipping, and an anti-seepage agent pool is not required to rise, so that the working stability is greatly improved. However, the structure is complex, the adaptability is poor, once the process is adjusted, the mechanism needs to be readjusted, the process is troublesome, and the maintenance is inconvenient.
