Technical field
The utility model relates to extruder technical field more particularly to a kind of screw extruders.
Background technique
Screw extruder is mainly used for squeezing out the thermoplastics such as soft, hard polyvinyl chloride, polyethylene, and a variety of plastics can be processed
Product, such as blown film, crowded pipe, pressing plate, hot candied band, also can be used for melt pelletization.Plastic extruder advanced design, quality is high, modeling
Change, low energy consumption, using Involutes Gears Transmission, with the features such as low noise, smooth running, bearing capacity is big, and the service life is long.Mesh
Before, in work, threaded portion is prone to wear screw extruder.
Based on the above considerations, the utility model devises a kind of screw extruder.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, adapt to reality and need, provide a kind of screw extruding
Machine.
In order to realize the purpose of this utility model, the technical solution adopted in the utility model are as follows:
The utility model discloses a kind of screw extruders, including barrel, are set to the charging of barrel one end top side wall
Bucket, screw rod, mouth mold and motor, the screw rod are set in the barrel, and one end of the screw rod and the output end of motor connect,
The other end is directed at mouth mold, and one end that the mouth mold is set to the barrel is connected to the barrel；The screw rod knot cylindrical
The outer wall of structure, the screw rod is equipped with threaded portion, and the threaded portion includes antetheca, rear wall and roof, and the roof is equipped with
Wearing plate.
Being fixed on the roof of the threaded portion for the wearing plate interval, is fixed with spacing board between the wearing plate.
It is equipped at intervals with several second wearing plates on the antetheca of the threaded portion, is equipped between second between second wearing plate
Spacing body
The wearing plate and the second wearing plate are carbine abrasion-proof plate.
The spacing board and the second spacing board are copper sheet.
The screw rod is steel screw rod, and the screw rod is different from wearing plate, the expansion of the second wearing plate, shrinking percentage.
The utility model has the beneficial effects that:
1. the wearability that the utility model increases threaded portion by the way that wearing plate is arranged on the roof of threaded portion, extending it makes
With the service life, reinforce the grinding efficiency of extruder；
2. the utility model is spaced by being arranged between wearing plate, when wearing plate can be prevented to be subjected to displacement, wearing plate
Between will not collide, avoid between wearing plate collision from generating wearing plate fragment and fall into material, influence product quality, reduce
The service life of wearing plate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of screw rod in the utility model.
In figure, 1 barrel, 2 feed hoppers, 3 screw rods, 4 mouth molds, 5 motors, 6 threaded portions, 61 antethecas, 62 rear walls, 63 roofs, 64
Wearing plate, 65 second wearing plates, 7 spacing boards, 8 second spacing boards.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
Referring to Fig. 1-Fig. 2.
The utility model discloses a kind of screw extruder, including barrel 1, be set to 1 one end top side wall of barrel into
Hopper 2, screw rod 3, mouth mold 4 and motor 5, the screw rod 3 are set in the barrel 1, one end and the motor 5 of the screw rod 3
Output end connection, the other end are directed at mouth mold 4, and one end that the mouth mold 4 is set to the barrel 1 is connected to the barrel 1；It is described
The structure cylindrical of screw rod 3, the outer wall of the screw rod 3 are equipped with threaded portion 6, the threaded portion 6 include antetheca 61, rear wall 62 with
And roof 63, the roof 63 are equipped with wearing plate 64, increase screw thread by the way that wearing plate 64 is arranged on the roof 63 of threaded portion 6
The wearability in portion 6, prolongs its service life, and reinforces the grinding efficiency of extruder.
What the wearing plate 64 was spaced is fixed on the roof 63 of the threaded portion 6, is fixed between the wearing plate 64
Spacing board 7, when extruder works, because the rotation of screw rod 3 applies shearing force to material, the wearing plate 64 on threaded portion 6 can be sent out
Raw certain displacement, is spaced by being arranged between wearing plate 64, when wearing plate 64 can be prevented to be subjected to displacement, wearing plate 64 it
Between will not collide, avoid between wearing plate 64 collision from generating 64 fragment of wearing plate and fall into material, influence product quality, subtract
The service life of few wearing plate 64, by spacing board 7 more soft relative to wearing plate 64 every interior setting therebetween, further
It avoids colliding between wearing plate 64, while increasing its flexibility.
It is equipped at intervals with several second wearing plates 65 on the antetheca 61 of the threaded portion 6, is set between second wearing plate 65
There is the second spacer 8, by the way that the second wearing plate 65 is arranged on the antetheca 61 of threaded portion 6, further increases the wear-resisting of threaded portion 6
Property, and reinforce extruder to the grinding efficiency of material, extend the service life of threaded portion 6.
The wearing plate 64 and the second wearing plate 65 are carbine abrasion-proof plate, are black hexagonal, have metallic luster, firmly
Degree is close with diamond to be suitable for that wearing plate is made.
The spacing board 7 and the second spacing board 8 are copper sheet, and copper is soft metal, will not be occurred because of collision broken etc.
Situation prevents it from falling in material, and can increase its flexibility.
The screw rod 3 is steel screw rod, and the screw rod 3 and wearing plate 64, the expansion of the second wearing plate 65, shrinking percentage are not
Together, its flexibility is further increased.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalents made based on the specification and figures of the utility model are applied directly or indirectly in relevant technology neck
Domain is also included in the patent protection scope of the utility model.
