A kind of it is prevented from the excessive Intermittert prefoaming machine discharging opening switching mechanism of material
Technical field
The present invention relates to a kind of Intermittert prefoaming machine discharging opening switching mechanism, more particularly to one kind to be prevented from material excessive
Intermittert prefoaming machine discharging opening switching mechanism.
Background technology
Intermittert prefoaming machine(Also known as quantitative prefoaming machine or adding pressure type prefoaming machine), be primarily used to fully-automatic packaging into
Type machine is supporting, by providing the pre- material issuings of EPS of the even density without caking phenomenon, to meet the shaping bar of packing articles production process
Part is required.
Chinese patent CN203110239U, arranges formula prefoaming machine for existing former Intermittert prefoaming machine discharge door in interval
Staving side, discharge door are aluminum casting, and are provided with guide pillar, and promote discharge door with cylinder, when staving is heated, due to various materials
The difference of the stockline coefficient of expansion, discharge door are easily stuck, and the discharge door accuracy of manufacture has high demands;Discharging locking required thrust is big, gas
Cylinder cylinder diameter requires big, waste compressed gas;Side discharging mechanism discharging time is long, discharges unclean;Discharging door locking required thrust
Greatly, cylinder bore requires big, the problem of waste compressed gas, discloses a kind of type pre-foaming machine, and which passes through discharging dodge gate and sets
Put in machine staving bottom, discharging dodge gate one end is connected by hinge and telophragma, and taper staving is arranged on transition installing plate
On, transition installing plate and telophragma are that the other end of the dodge gate that discharges is connected by hinge and oscillating cylinder by screw connection
Connect, oscillating cylinder is installed by the cylinder mounting seat being connected on staving, sealing strip is arranged on telophragma and discharging dodge gate
Between.When the dodge gate that discharges discharges, oscillating cylinder piston rod stretches out, and promotes discharging dodge gate around hinge to turn to certain angle
Degree, discharging dodge gate are opened, machine quickly discharging, and when cylinder is tensed, the mode of discharging activity door closure overcomes former interval
Formula prefoaming machine discharge door is arranged on Intermittert prefoaming machine staving side, and discharge door is aluminum casting, and is provided with guide pillar, and is pushed away with cylinder
Dynamic discharge door, when staving is heated, due to the difference of various linear expansion coefficients, discharge door is easily stuck, and discharge door is manufactured
Required precision is high;Discharging locking required thrust is big, and cylinder bore requires greatly, to waste compressed gas;Side discharging mechanism discharging time
Long, discharge unclean;Discharging door locking required thrust is big, and cylinder bore requires big, the problem of waste compressed gas, but is gone out due to which
The other end of material dodge gate is connected by hinge and oscillating cylinder, and in discharging, material is readily flowed on oscillating cylinder piston rod,
And bad in the effect of discharging activity door closure, so as to discharging can be caused unclean, serious waste is caused to material, can be gone out
The excessive phenomenon of existing material, and be difficult to clean which.
To sum up, need to research and develop a kind of clean discharging, good discharging effect at present, waste that is reducing material, be not in thing
That expects excessive phenomenon is prevented from the excessive Intermittert prefoaming machine discharging opening switching mechanism of material, overcomes meeting in prior art
Cause discharging clean, serious waste is caused to material, it may appear that the excessive phenomenon of material, and be difficult to clean which
Shortcoming.
Content of the invention
