Description
Technical field
The utility model is related to extruder field of plastics processing, in particular to a kind of single screw extrusion machine.
Background technology
In the production of existing extruder, material is put into after the machine barrel of extruder, the rotation through screw rod, extrudes and stirs
Mix, material fusion plastification under certain temperature action, and under screw rod promotion, die ring is passed through after screen pack, flow distribution plate
The gap extrusion molding of shape mouth mold, eventually passes cooling and shaping finished product.
Flow distribution plate and screen pack that transition region between the mouth mold and screw head of extruder is set, its effect is to make stream
Linear motion is changed into from screw, prevents the particle not melted from entering mouth mold, metal impurities is filtered off, in addition, flow distribution plate is also
Solution pressure can be improved, make product denser, when material is by eyelet, be able to further it is homogenous plasticized, with control modeling
Change quality.Therefore filtering is a critically important part in extruder production work, and it is directly connected to the quality of product, so
And in existing equipment, the blockage problem of screen pack but often occurs, cause whole production process must not infrequently interrupt into
Row cleaning, influences production efficiency.
Utility model content
To solve the deficiencies in the prior art, the utility model provides a kind of extruder from belt scraping plate, can be whole
Constantly filter screen is cleaned in production process, and it makes full use of the power of screw rod and its fluid of extrusion, economizes on resources.
The utility model adopts the following technical scheme that to realize above-mentioned purpose：
The utility model provides a kind of extruder, including feed hopper, reduction gear box, screw rod, filter screen, deflector, goes out
Material mouth and swivel nut, the screw rod are placed in swivel nut, and reduction gear box is connected by bull stick with screw rod, swivel nut upper end and feed hopper phase
Connection, the other end of screw rod is filter screen and deflector, and the opposite side of the deflector is discharging opening, it is characterised in that the spiral shell
Scraper plate is fixed with the screw head of bar, the scraper plate side is fitted with filter screen.
Preferably, the scraper plate is arc, and the side upper and lower ends of the scraper plate are fixed by axle with screw head respectively
Connection, opposite side is close to filter screen.
Specifically, the direction of the scraper plate arc opening is opposite with screw rod steering.
Preferably, the scraper plate is provided with some holes.
Preferably, some steel balls are placed between the screw head and filter screen.
Specifically, the diameter of the steel ball is less than the aperture of the hole on scraper plate.
Preferably, the scraper plate is close to the side of filter screen provided with scraping blade.
Preferably, the screw head is in half rugby shape, is fixed on by fixed seat on screw rod.
Specifically, rounding off at the top of the screw head.
Specifically, scraper plate side upper and lower ends are fixed on screw head by axle, and middle part is fixed on screw head
Top.
The utility model fixes scraper plate at the top of screw head, constantly filter screen can be carried out in whole production process
Cleaning；Place steel ball and hole is set on scraper plate, can also be played well while cleaning effect is further increased
Immixture；The direction of arc scraper plate arc opening is turned to screw rod on the contrary, the dynamic of the fluid of Screw Extrusion can be made full use of
Power, effectively reduces resistance, economizes on resources；The temperature for being designed to be homogenized exit melt on its head, makes process stabilizing；This reality
Mixing can also be effectively facilitated with new design, improves material performance, makes obtained properties of product stable homogeneous.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model extruder；
Fig. 2 is the structural representation that the utility model extrudes machine scraper.
Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of extruder provided by the utility model, including feed hopper 2, reduction gear box 1, screw rod 3,
Filter screen 6, deflector 7, discharging opening 8 and swivel nut, screw rod 3 are placed in swivel nut, and reduction gear box 1 is connected by bull stick with screw rod 3, spiral shell
Set upper side is connected with feed hopper 2, and the other end of screw rod 3 is filter screen 6 and deflector 7, and the opposite side of deflector 7 is discharging opening 8.
In order to reduce the blocking of filter screen, scraper plate 5 is fixed on the screw head of screw rod 3, the side of scraper plate 5 is fitted with filter screen, it is other not do in detail
Thin description is with reference to prior art.
As shown in Fig. 2 the scraper plate 5 is designed as arc, its side is designed with for fixed hole 9, its by axle with
Screw head 4 is fixedly connected, and opposite side is close to filter screen 6, and the side that its scraper plate 5 is close to filter screen 6 is further provided with scraping blade, reduces its right
The infringement of filter screen；Hole 10 is additionally provided with scraper plate 5, good immixture can also be played while being cleaned, and
And resistance suffered by scraper plate 5 can be reduced, play a protective role.
The direction of the arc opening of scraper plate 5 is turned to screw rod 3 on the contrary, it, which can effectively utilize screw rod, rotates drive stream
Revolving force produced by body, the resistance suffered by further reduction scraper plate 5 and its axle, can also while playing a protective role
Economize on resources.
Some steel balls are placed between the screw head 4 and filter screen 6, its diameter is less than the aperture of hole 10 on scraper plate, its
Good cleaning action can be further played under the driving of scraper plate and fluid, is made while good mixing can also be played
