Description
Technical field
The present invention relates to a kind of extrusion apparatus, particularly relate to prevent the full-automatic extrusion apparatus of feed blocking.
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 prevents thing
The full-automatic extrusion apparatus of material blocking.
Technical scheme is as follows:
Prevent the full-automatic extrusion apparatus of feed blocking, 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.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.
As the preferred structure of the present invention, 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 stirring of cross bar around through hole rotary bar again with transverse shifting cross bar
Mix effect.
Further, cross bar stretches into and is vertically connected with puddler on one end of breeze way.Vertically disposed puddler can
Increase the stirring scope of raw material.
For the present invention is better achieved, described extruder includes barrel, the screw rod being arranged in barrel, and feed hopper is connected to
On the sidewall of barrel upper end, the inner chamber of described barrel is conical cavity, and screw rod is the conical screw that the conical cavity with barrel matches.Spiral shell
Bar and barrel are mutually matched so that raw material can be by bigger and uniform extruding force between barrel inwall and screw rod outer surface
Degree, the mixing extrusion processing of the multicomponent plastic material that applicable big compression ratio, melt index are relatively low.
Further, the outer wall of barrel being provided with zone of heating, screw rod is cored screw, and the intracavity sidewall of screw rod is arranged
There is thermal insulation layer.Being provided for raw material heating of zone of heating, raw material is easy to die head injection mo(u)lding after adding heat fusing.Setting of thermal insulation layer
Put and avoid heat to radiate to the inner chamber of screw rod, allow heat concentrate between barrel and screw rod, be saved greatly the energy.
For the present invention is better achieved, described zone of heating is coated with heat-insulation layer, and heat-insulation layer is tapetum fibrosum.Setting of heat-insulation layer
Putting it can be avoided that dissipate outside heat, heat-insulation layer uses tapetum fibrosum, compared with other materials, better heat preservation.
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.
3, 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.
4, vertically disposed puddler can increase the stirring scope of raw material.
5, screw rod and barrel are mutually matched so that raw material can be by relatively big and equal between barrel inwall and screw rod outer surface
Even extruding dynamics, the mixing extrusion processing of the multicomponent plastic material that applicable big compression ratio, melt index are relatively low.
6, the setting of thermal insulation layer avoids heat to radiate to the inner chamber of screw rod, allows heat concentrate between barrel and screw rod, greatly
The earth has saved the energy.
7, the setting of heat-insulation layer is it can be avoided that dissipate outside heat, and heat-insulation layer uses tapetum fibrosum, compared with other materials, and insulation effect
Fruit is more preferably.
