Description

A kind of flame retardant plastics process equipment

Technical field

The invention belongs to technical field of plastic, more particularly, to a kind of flame retardant plastics process equipment.

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 207388050 U of Chinese patent CN discloses a kind of " plastic grain stirring Mechanism " comprising agitator, the first hopper, the second hopper, end plate, several paddles, agitating shaft and agitating shaft driving machine Structure, the upper end of the agitator offer feed inlet, and the lower end of agitator offers discharge port；The agitating shaft can be rotated longitudinal It is set 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 agitating shaft Upper 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 Driving mechanism is drivingly connected in the agitating shaft；It is docked with the feed inlet port of first hopper.

But under this kind of structure, the mixture homogeneity of the material obtained after stirring is lower, and material carries out in screw extruder It is easy to appear the case where partially lacking at fire retardant after melting, and then flame retardant of plastic effect is impacted.

Summary of the invention

The present invention for overcome the deficiencies in the prior art, provides a kind of processing of the flame retardant plastics that granule materials stir evenly and sets It is standby.

To achieve the goals above, the invention adopts the following technical scheme: a kind of flame retardant plastics process equipment, including stirring Room, set on the agitating paddle for stirring indoor agitating shaft, being connected with the agitating shaft, the driving for driving the mixing component to rotate Part and air ejection member；The air ejection member includes gas passage in the agitating paddle, is set on agitating paddle and the gas Multiple fumaroles that channel is connected, the air storing cavity being connected in agitating shaft with the gas passage, setting of can moving up and down In the piston in air storing cavity and the displacement drive component for driving the piston to move up and down；In the agitating shaft rotation process, The driving part will drive the piston to move up and down；When it is described piston moves downward when, the gas in the air storing cavity can It is sprayed outward by the fumarole.By the outside jet of fumarole being arranged on agitating paddle in the present invention, and then realizes and stir Axis is mixed in rotation, the fumarole on agitating paddle is by peening particle material, so that material is by jet, in the process moved upwards The middle effect that dispersion mixing occurs, for the traditional stress stirring of rubber, material dispersion degree is big, and mixed effect is good, in turn The case where fire retardant is unevenly distributed when the material later period effectively being avoided to melt, improves the quality for the plastics being prepared；Its It is secondary, the piston can be directly driven in the rotation process of agitating shaft and is moved, and then it is not necessary that power source is still further arranged Drive piston 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.

Further, the conflict component include the extension rod extended outward to form by mobile bar top and be set to extension rod On sliding block, the top of the sliding block is matched with the track；Track setting is on sliding block top, and then when mobile bar being driven to move down To push mobile bar, in the case where guaranteeing that gas storage intracavity gas is sufficient, mobile bar is able to drive piston and moves down；Compared to rail Road was located at for the case where sliding block lower part, and the operation that piston moves down is more easy, and was less prone to the case where can not moving down, failure Rate is low.

Further, the track is circumferentially spaced at least three protrusion, and the height of the protrusion is less than the track Height；In the agitating shaft rotation process, the protrusion will push the sliding block, and then drive the mobile bar band piston It moves down；Mobile bar is pushed using protrusion, pushing works well, and the dynamics that gas has fumarole to spray is strong, and then preferably makes For material by upward jet, mixed effect is be more good；Since the height of protrusion is less than track, it ensure that sliding block in rotation It will not be dropped out from track, reduce failure rate.

Further, it is equipped in the agitating shaft for driving the mobile bar automatically multiple upwards after the mobile bar moves down The elastic component of position；By the setting of elastic component, guarantee to reset upwards after mobile bar moves down, so that air storing cavity is in outlet After can be realized gas supplement, piston can also reset on the position positioned at air storing cavity top, guarantee that jet operates next time Be normally carried out.

Further, the fumarole is equipped with unidirectional outlet part；And then fumarole only can outside jet, be not in The case where inside air-breathing, avoids the occurrence of granule materials and is blocked in fumarole in the inside air-breathing of fumarole or is adsorbed to contain and spraying The case where stomata position, guarantees that material is in dispersity always, and convenient for mixing, mixed effect is good, the object after the completion of stirring Expect that mixture homogeneity is high.

Further, it is equipped with first passage in the piston, is equipped in the mobile bar and is connected with the first passage Second channel；The second channel is equipped with one-way air inlet part；During mobile bar band piston moves up, list can be passed through It supplies gas to air intake into air storing cavity, supplements the gas in air storing cavity；Secondly, one-way air inlet part will not outside jet, Jin Erbao Piston is demonstrate,proved when moving down, the gas in air storing cavity is sprayed from fumarole outward always, and gas is avoided to be sprayed outward by second channel And weaken the dynamics of fumarole jet.

Further, the agitating shaft is equipped with the inserting groove being connected with the air storing cavity, and the agitating paddle is equipped with The exntension tubs being spirally connected with the inserting groove, the exntension tubs are equipped with the opening being connected with the air storing cavity；By by agitating paddle with Agitating shaft is set as being detachably connected, and then convenient for replacing to agitating paddle；By the setting of exntension tubs, realize agitating paddle with Agitating shaft is stably connected with, and is effectively avoided the case where junction leaks.

Further, the piston outer wall is close equipped with the first seal matched with the gas storage cavity wall and second Sealing；Sealing effect between piston and air storing cavity guarantees the outlet and the air inlet that can be realized air storing cavity when piston moves up and down.

In conclusion the invention has the following advantages that stress stirring and jet stirring are combined, realization is to the good of material Stirring, material dispersion degree is big, and mixed effect is good, improves the quality for the plastics being prepared；Secondly, in the rotation of agitating shaft The piston can be directly driven in the process to move, and then mobile without still further setting power source drive piston, save Energy consumption.
