Description
Technical field
The present invention relates to extrusion molding apparatus field, and in particular to a kind of wood moulding extrusion molding apparatus.
Background technology
Wood plastic composite includes plastics, thus with preferable modulus of elasticity, but due to include wood fibre and through with
Plastics are sufficiently mixed, thus with the physical and mechanical properties such as the resistance to compression suitable with hardwood, counter-bending, and its durable performance is obvious
Better than common wood materials.Wood-plastic board case hardness is high, usually 2-5 times of timber, with log identical processing characteristics,
Can follow closely, can bore, it is cleavable, cohesive, fixed with nail or bolt connection, surface it is smooth it is fine and smooth, without sanding and paint, it is painted
Tack is good, also can be according to personal like's japanning.
In the extrusion or injection process of plastics and its wood plastic product, in plasticizing, material needs to add by feeding hopper and squeezed
Go out machine plasticizing apparatus, because the coefficient of friction of wood moulding raw material is larger, often the phenomenon of spout putty occur in feeding procedure.
Extruded in addition for wood moulding, it is very important that it is well mixed, but is mixed in plasticizing apparatus machine because space is small, and material rubs
Wipe coefficient big, mixing efficiency is very low in machine, and in manufacturing process, added materials according to each composition accounting difference
, such as the ratio shared by wood powder is not very big, and it is intermittent feed, and existing intermittence feed is more by artificial warp
Test, influence the quality of wood-plastic board.
The content of the invention
It is an object of the invention to provide a kind of wood moulding extrusion molding apparatus, the device can carry out interval to wood powder
Feed, it is ensured that the quality of wood-plastic board.
To reach above-mentioned purpose, base case of the invention is as follows：A kind of wood moulding extrusion molding apparatus, including extruder,
The extruder is provided with feed hopper, in addition to structure for conveying, the structure for conveying include motor, cam, connecting rod, crossbeam,
Slide plate and rack, the feed hopper include inner and outer wall, the feed cavity of inwall formation wood powder, the feed cavity top and
Bottom is respectively charging aperture and discharging opening, and the discharging opening is connected with extruder, is vented cavity, the ventilation between inner and outer wall
Chamber top is air inlet, and air inlet is provided with heating arrangement, and the inwall is circumferentially with multiple through holes, the motor output shaft with
Cam is connected, and described rack one end at cam eccentric with being hinged, and the rack and pinion engagement, the gear connects with holder pivots
Connect, the support is connected with slide plate slides, connecting rod one end offsets with cam, the other end is connected with slide plate upper end, the connection
It is hinged in the middle part of bar with crossbeam, the gear is located in feed cavity and is connected with agitating plate, and the agitating plate is located at discharge outlet.
During using this base case, by the feedstock transportations such as wood powder to feed hopper.Air inlet structure can produce wind through air inlet
Enter in vented cavity, then entered by through hole in feed cavity., can be to entering because having addition structure in air inlet
Air into feed cavity is heated, and air is blown into feed cavity and it can be dried.And air is entered
After in feed cavity, the air pressure of feed cavity can be increased, powder is entered extrusion molding in extruder as early as possible.Compared to it is existing only according to
Gravity is depend on to convey powder, it is more efficient and be difficult to bond.While material is conveyed, start motor, motor driving cam
Rotate, and because cam offsets with connecting rod one end, in cam rotation, connecting rod can produce rotation along crossbeam,
When one end that connecting rod is connected with cam is moved down, the connecting rod other end drives slide plate to move up, and this hour rack is upward
It is mobile, no longer engaged with gear, gear is not rotated further by.When an end position of connecting rod and cam contact is increased, now connect
Bar position is relatively low, rack and pinion engagement, drives pinion rotation.Pinion rotation drives agitating plate movement, by wood powder from discharging opening
In the extruder of discharge.So, cam is often rotated once, will make gear intermittence rotation, i.e. agitating plate intermittence is rotated, real
Existing intermittent feed.
Preferred scheme one：Based on scheme preferred scheme, the slide plate upper end is hinged with connector, and the rack is set
There is chute, the connector coordinates with slide.Connector and rack coordinate, it is ensured that rack can be with tooth when downward
Wheel engagement.
Preferred scheme two：Preferably one preferred scheme, in addition to air channel, the one end of the cam away from motor
Provided with rotating shaft, the rotating shaft is provided with flabellum, and the flabellum is connected with air channel one end, and the air channel other end connects with air inlet
It is logical.In cam rotation, flabellum can be driven to rotate, fan blade rotating movable property life wind-force enters to wind pushing cavity by air channel and air inlet
In entered again by through hole in wood powder conveyor chamber.It so just can only complete stirring and air-supply, operation simultaneously by a motor
It is very convenient.
Preferred scheme three：Based on scheme preferred scheme, the through hole be from inwall outer end inboard end diagonally downward
Set, it is convenient that powder is rapidly introduced into extruder.

Fig. 1 is the schematic diagram of wood moulding extrusion molding apparatus structure for conveying of the present invention；
Fig. 2 is the schematic diagram of feed hopper of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Cam 1, rack 2, chute 3, gear 4, connector 5, slide plate 6, connecting rod 7,
Crossbeam 8, feed hopper 9, through hole 10, discharging opening 11, feed cavity 12, charging aperture 13, air inlet 14, vented cavity 15.
Embodiment is substantially as shown in Figure 1：Embodiment is substantially as shown in Figure 1：A kind of wood moulding extrusion molding apparatus, including
Extruder, extruder is provided with feed hopper 9, in addition to structure for conveying.Feed hopper 9 includes inner and outer wall, inwall formation wood powder
Feed cavity 12, the upper and lower part of feed cavity 12 is respectively charging aperture 13 and discharging opening 11, and discharging opening 11 is connected with extruder, interior
It is vented cavity 15 between wall and outer wall, the top of vented cavity 15 is that heating arrangement is provided with air inlet 14, air inlet 14, and inwall is circumferentially set
There are multiple through holes 10.Through hole 10 is convenient that powder is rapidly introduced into extruder to be set diagonally downward from inwall outer end inboard end
In.
As shown in Fig. 2 structure for conveying includes motor, cam 1, connecting rod 7, crossbeam 8, slide plate 6 and rack 2.Motor is exported
Axle is connected with cam 1, and the one end of rack 2 at cam eccentric with being hinged, and rack 2 is engaged with gear 4, and gear 4 is connected with holder pivots,
Support is slidably connected with slide plate 6, and the one end of connecting rod 7 offsets with cam, and the other end is connected with the upper end of slide plate 6, the middle part of connecting rod 7 with
Crossbeam 8 is hinged, and gear 4 is located in feed cavity 12 and is connected with agitating plate, and agitating plate is located at discharging opening 11.Cut with scissors the upper end of slide plate 6
Connector 5 is connected to, rack 2 is provided with chute 3, and connector 5 is slidably matched with chute 3.Connector 5 coordinates with rack 2, it is ensured that
Rack 2 can be engaged with gear 4 when downward.Wherein, cam is cam made of iron, and connecting rod 7 and one end of cam contact are
Magnetic part, so can have magnetic force, it can be ensured that cam is contacted with connecting rod 7 with cam and connecting rod 7.
By in the feedstock transportations such as wood powder to feed hopper 9.Air inlet structure can produce wind and enter vented cavity 15 through air inlet 14
In, then entered by through hole 10 in feed cavity 12., can be to entering charging because there is addition structure at air inlet 14
