A kind of plastic raw materials mixing plant that material is uniformly mixed
Technical field
The invention belongs to technical field of plastic, set more particularly, to the plastic raw materials stirring that a kind of material is uniformly mixed
It is standby.
Background technique
The basic process of plastic products processing is extrusion moulding after melting plastic grain, and flame retardant plastics is usually required preceding
Phase stirs evenly plastic grain and fire retardant.As Chinese patent CN 207388050U discloses a kind of " plastic grain blender
Structure " comprising agitator, the first hopper, the second hopper, end plate, several paddles, agitating shaft and agitating shaft driving mechanism,
The upper end of the agitator offers feed inlet, and the lower end of agitator offers discharge port;The agitating shaft can be rotated longitudinal set
It is placed in the middle part of agitator and agitating shaft is located at the lower section of the feed inlet;The end plate fixation is horizontally placed on the upper of agitating shaft
End, so that the upper side of end plate is opposite with feed inlet;Several paddles are uniformly connected on agitating shaft;The agitating shaft drives
Motivation structure is drivingly connected in the agitating shaft;It is docked with the feed inlet port of first hopper.
Under this kind of structure, be generally difficult to be stirred to the raw material of teeter chamber bottom so that the raw material of teeter chamber bottom without
Method realizes that uniformly mixing, raw material mixed effect are poor.
Summary of the invention
The present invention for overcome the deficiencies in the prior art, provides what a kind of good material of raw material mixed effect was uniformly mixed
Plastic raw materials mixing plant.
To achieve the goals above, the invention adopts the following technical scheme: the plastic raw materials that a kind of material is uniformly mixed stir
Mixing equipment, including teeter chamber, set on the agitating paddle for stirring indoor agitating shaft, being connected with the agitating shaft, for stirring described in driving
Mix the actuator and air ejection member of component rotation;The teeter chamber bottom is equipped with the bottom stirring group matched with the agitating shaft
Part, the agitating shaft can drive the bottom mixing component to rotate and be stirred with the material to teeter chamber bottom when rotating
Mixing.By being provided with bottom mixing component in teeter chamber bottom in the present invention, and then can will be stirred by the bottom mixing component
The material for mixing room bottom is mixed, and the material scattering for being deposited on teeter chamber bottom is stirred, and realizes the uniform mixed of material
It closes, improves the mixture homogeneity of plastic raw materials.
Further, the bottom mixing component includes rotating disc, multiple stirring bars on rotating disc upper surface, consolidates
Surely the shaft being arranged on the rotating disc and the spline structure for realizing the rotation stop cooperation between the shaft and the agitating shaft;
Due to the setting of spline structure, so that rotating disc can drive realization to rotate directly under the rotation of agitating shaft, it is another to no longer need to setting
Outer power source, low energy consumption, energy saving.
Further, the spline structure includes set on the open slot of the shaft bottom, in the open slot
Rotation stopper recess and the rotation stop protrusion matched in the shaft with the rotation stopper recess;Rotation stop protrusion is inserted into rotation stopper recess
It is interior, the case where realizing the stabilization rotation stop between agitating shaft and shaft, be less prone to skidding.
Further, the teeter chamber bottom is equipped with support column, and the rotating disc is equipped with the column penetrated for the support column
Slot;By the setting of support column, rotation pan bottom is avoided to be close to teeter chamber bottom, the friction being subject to when reducing turn disc
Power.
Further, bearing part is equipped between the support column outer wall and the column slot inner wall;By the setting of bearing part,
The frictional force between support column and column slot is reduced, the rotation of rotating disc is more smoothly.
Further, the air ejection member includes being set to the gas passage in the agitating paddle, being set on agitating paddle and be somebody's turn to do
Multiple fumaroles that gas passage is connected, can move up and down the air storing cavity being connected in agitating shaft with the gas passage
The piston being placed in air storing cavity and displacement drive component for driving the piston to move up and down;The agitating shaft rotation process
In, the driving part will drive the piston to move up and down;When it is described piston moves downward when, gas in the air storing cavity
It can be sprayed outward by the fumarole;By the outside jet of the fumarole being arranged on agitating paddle, and then realize that agitating shaft exists
When rotation, fumarole on agitating paddle is by peening particle material, so that material is by jet, during moving upwards
The effect of dispersion mixing, for the traditional stress stirring of rubber, material dispersion degree is big, and mixed effect is good, and then effectively keeps away
The case where fire retardant is unevenly distributed when exempting from the melting of material later period, improves the quality for the plastics being prepared;Secondly, stirring
The piston can be directly driven by mixing in the rotation process of axis moves, and then it is not necessary that power source drive piston is still further arranged
It is mobile, energy saving.
Further, the displacement drive component includes the mobile bar being connected with the piston, is set in the agitating shaft
For the up and down through slot of the mobile bar, the drive seat in teeter chamber and the track in the drive seat;The movement
Bar top is pierced by the teeter chamber top and is connected with the conflict component matched with the track;Pass through track and abutting portion
The driving that moves up and down to mobile bar is realized in part cooperation, and track can realize good limit positioning action to component is contradicted, avoid
Agitating shaft occurs the case where contradicting component and track derailing in rotation;And it contradicts component and track and is carried out in the external of teeter chamber
Cooperation is repaired more convenient.
In conclusion the invention has the following advantages that by being provided with bottom mixing component, Jin Erke in teeter chamber bottom
The material of teeter chamber bottom is mixed by the bottom mixing component, the material scattering of teeter chamber bottom will be deposited on
Stirring, realizes the uniform mixing of material, improves the mixture homogeneity of plastic raw materials.
