Description
Technical field
The present invention relates to a kind of pressurizing unit, the full-automatic pressurizing unit produced particularly for plastic cement.
Background technology
Plasthetics is modal in daily life, as in household electrical appliance, instrument and meter, construction equipment, automobile work
The various fields such as industry, haberdashery and hardware, the communication apparatus and medical apparatus and instruments, the use ratio of plasthetics the most rapidly increases.This
Mainly having following reason: the first, plastic cement is easily worked compared with metal material, production efficiency is high, saves the energy, insulating properties
Can be good, relative density is about 1.0-1.4, lighter half than aluminum, lighter by 3/4 than steel, has prominent wear-resisting, decay resistance；The second,
Daily with in industrial products, a plasthetics reasonable in design tends to replace multiple conventional metal frames part, adds
The distinctive character of utilizing works plastics, with the extremely complex shape of one-shot forming, and can also be designed to clamping structure, thus
Reduce the various securing members of assembling in product, reduce metal material consumption and processing and assembly work.
Obtain the process of injection-molded item, referred to as injection mo(u)lding or injection moulding, or referred to as injection simply.Note
Molded basic process is: granular macromolecular material (hereinafter referred to as plastics) is through the extruding of screw in injection molding machine and adds
Heat, becomes the melt that can flow of molten condition.Under the promotion of screw rod, plastic melt is by injection molding machine nozzle, mould
Sprue, sub-runner and cast gate enter mold cavity, mold the process with definite shape and gauge articles.Existing injection is big
Use feed hoppers charging more, pour into process raw material time, due to action of gravity, can pile up in discharge outlet and cause feed hopper
Blocking, thus affect the properly functioning of equipment.
Summary of the invention
Easily blocking feed hopper thus the properly functioning defect of the equipment that affects for solving raw material, spy of the present invention provides and is used for moulding
The full-automatic pressurizing unit that glue produces.
Technical scheme is as follows:
The full-automatic pressurizing unit produced for plastic cement, including feed hopper and the breeze way that is arranged on feed hopper lower end,
Connecting on breeze way and have extruder, the discharge end of extruder is provided with die head；It is provided with gear on the upper end sidewall of described feed hopper
Plate, both sides, the lower end inwall of feed hopper is respectively arranged with obstruction bar；Offer through hole on the sidewall of breeze way, through hole interts
Having cross bar, one end of cross bar is arranged in breeze way, the other end is arranged on outside breeze way；Described extruder includes barrel, setting
Screw rod in barrel, feed hopper is connected on the sidewall of barrel upper end, and the inner chamber of barrel is conical cavity, and screw rod is the cone with barrel
The conical screw that shape chamber matches；Described die head includes shell, the electromagnetic heating coil being wrapped on shell, on the front end face of shell
Offering extrusion cavities, shell is provided with the fixing pipe connected with extrusion cavities, and the outer sheath of fixing pipe is provided with defecator, filters dress
The one end put is fixed in the inner chamber of shell, and fixing pipe offers several hand-holes.Raw material after pouring feed hopper into, due to
The effect of baffle plate, falling speed will decline, and the raw material continuing from baffle plate both sides to fall can run into the stop stopping bar again, falls
Speed reduces further.Raw material falling speed too fast blocking feed hopper is avoided in baffle plate, the setting of obstruction bar.Cross bar in breeze way
For raw material is stirred so that the raw material in breeze way can sequentially enter in extruder, it is to avoid raw material blocking breeze way
Affect the properly functioning of equipment.Screw rod and barrel are mutually matched so that raw material can be hard to bear between barrel inwall and screw rod outer surface
To extruding more greatly and uniformly dynamics, the mixing extrusion of the multicomponent plastic material that applicable big compression ratio, melt index are relatively low adds
Work.After raw material enters die head after extruder compacting mixing, under the heating of electromagnetic heating coil, start fusing, through defecator mistake
After filter impurity, entered in fixing pipe by hand-hole, finally discharge from extrusion cavities, it is ensured that molding effect.
As the preferred structure of the present invention, described defecator is drainage screen.Drainage screen in this programme is used for filtering miscellaneous
Matter, dismantles and installs the most more convenient.
Further, the heat-insulation layer being arranged on outside electromagnetic heating coil is also included.The setting of heat-insulation layer is it can be avoided that heat
Outer scattered.
For the present invention is better achieved, the diameter of described through hole is more than the diameter of cross bar.The diameter of through hole is more than cross bar
Diameter, staff both can substantially increase the stirring of cross bar around through hole rotary bar again with transverse shifting cross bar
Effect.
Further, described cross bar stretches into and is vertically connected with puddler on one end of breeze way.Vertically disposed puddler
The stirring scope of raw material can be increased.
In sum, the invention has the beneficial effects as follows:
1, raw material is after pouring feed hopper into, and due to the effect of baffle plate, falling speed will decline, and continue from baffle plate both sides to fall
Raw material can again run into stop bar stop, falling speed reduces further.Baffle plate, the setting of obstruction bar avoid raw material to fall
Excessive velocities blocking feed hopper.
2, the cross bar in breeze way is for being stirred raw material so that the raw material in breeze way can sequentially enter extruding
In machine, it is to avoid raw material blocking breeze way affects the properly functioning of equipment.Screw rod and barrel are mutually matched so that raw material is in barrel
Can be by extruding more greatly and uniformly dynamics between wall and screw rod outer surface, be suitable for that big compression ratio, melt index are relatively low many groups
Divide the mixing extrusion processing of plastic material.
3, after raw material enters die head after extruder compacting mixing, under the heating of electromagnetic heating coil, start fusing, pass through
After filter device impurity screening, entered in fixing pipe by hand-hole, finally discharge from extrusion cavities, it is ensured that molding effect.
4, drainage screen is used for impurity screening, dismantles and install the most more convenient.
5, the setting of heat-insulation layer is it can be avoided that dissipate outside heat.
6, the diameter of through hole is more than the diameter of cross bar, and staff both can be with transverse shifting cross bar, again can be around through hole
Rotary bar, substantially increases the mixing effect of cross bar.
7, vertically disposed puddler can increase the stirring scope of raw material.
