Abstract
The utility model relates to a plastics production machinery discloses a lower hopper that extruder was used very much. The sliding type insulating tool comprises a body, the body is inverted circular truncated cone, the body includes the rotatory bucket body of outer fixed bucket body and inlayer, fixed bucket body and rotatory bucket body are respectively at last lower extreme sliding connection, the motor is connected to fixed bucket body upper end, the output of motor down and connect the rotation axis, the rotation axis lower extreme is connected with the lower extreme of rotatory bucket body, fixed bucket body upper end is equipped with brush or doctor -bar, brush or doctor -bar and rotatory bucket body inner wall contact and identical with the inner wall of rotatory bucket body. The utility model discloses an agitating unit makes plastic pellet be in constantly flow state, has prevented not only that plastic pellet from blocking, has more accelerated plastic pellet's falling speed, has improved work efficiency, and setting up of doctor -bar or brush makes plastic pellet can not remain on the hopper inner wall, is favorable to plastic pellet's flow and whereabouts, is convenient for clear up the hopper inner wall.
Description
(1) technical field
This utility model relates to plastics-production mechanical field, particularly to the hopper of a kind of extruder.
(2) background technology
Plastics are with monomer as raw material, by addition polymerization or the macromolecular compound of polycondensation reaction, work as at daily life
In be widely used.During plastics-production, will use a lot of plant equipment, such as foaming machine, extruder, pelleter etc., mould
Raw material is heated by material extruder, melted, and after plastic extruder extrudes, from its head, the bar of extrusion molding moulds
Material, bar plastic through supercooling laggard enter to pelleter, through pelleter, bar plastic is made the plastic pellet of given size.
In plastic extruding forming equipment, plastic extruder is normally referred to as main frame, and becomes with its supporting follow-up equipment plastic extrusion
Type machine then becomes subsidiary engine.Plastic extruder mainly includes extrusion system, drive system and heating and cooling system these three system.And
In extrusion system, including again screw rod, machine barrel, hopper, head and mould, plastics are plastified uniformly by extrusion system
Under melt, and set up pressure, by screw rod continuous print extruder head.Screw rod: be the main portion of extruding machine
Part, it is directly connected to range of application and the productivity ratio of extruding machine, is made up of the steel alloy of high-strength corrosion-resisting.Machine barrel: be one
Metallic cylinder, typically with heat-resisting, compressive resistance is higher, firm steel alloy wear-resisting, corrosion resistant or the clad steel of interliner alloy steel
Pipe is made.Hopper: feed hopper bottom is equipped with cutting device, in order to adjust and cut off stream, the side of hopper is equipped with window and demarcation
Metering device.Head and mould: head is made up of steel alloy inner sleeve and carbon steel overcoat, and head is built with mould, head
Effect be the plastic melt of rotary motion is changed into parallel lines motion, in the importing die sleeve of uniform and stable, and give mould
Expect with necessary briquetting pressure.
At present, the hopper of the extruder on market, mostly substantially be inverted hollow vertebral body, up big and down small, blanking time
Waiting, only need to be opened by the plastic pellet bag of sack, and be poured in big mouth, plastic pellet will be along the downward landing of bucket wall to entering
Material mouth, carries out subsequent handling.It will be apparent that owing to the bore of feed opening is less；When substantial amounts of plastic pellet pours hopper into simultaneously,
Plastic pellet granule does not far catch up with the speed that above hopper, plastic pellet is toppled over, so due to plastic pellet in the falling speed of feed opening
Friction between grain and bucket wall, the internal friction between plastic pellet and plastic pellet, bridge formation will be caused at feed opening, take arch,
Then the situation of blockage of discharging hopper is produced.When plastics granulosa up is increasingly thicker, the pressure producing bucket wall the most more comes
The biggest so that stiction is increasing, feed opening is the most more not easy dredging.Thus have impact on whole squeezing
Go out the running of machine.At this moment it is accomplished by dredging, so in concrete production process just in hands is stretched into hopper by operator
Add loaded down with trivial details degree, the most convenient.Further, since plastics have absorption property, therefore in blanking process, plastic pellet is easily inhaled
It is attached on hopper inwall, bad cleaning, the most also have impact on production efficiency.
(3) summary of the invention
This utility model is in order to make up the defect of prior art, it is provided that a kind of not wall built-up, nonclogging extruder
Hopper.
This utility model is achieved by the following technical solution:
The hopper of a kind of extruder, including body, is characterized in that, described body is reverse frustoconic, described body bag
Include the fixing bucket body of outer layer and the rotation bucket body of internal layer, described fixing bucket body and rotation bucket body to be slidably connected at upper and lower side respectively,
Described fixing bucket body upper end connects motor, and the outfan of described motor down and connects rotary shaft, described rotary shaft lower end and rotation
The lower end of rotating bucket body connects, and described fixing bucket body upper end is provided with hairbrush or scraping blade, described hairbrush or scraping blade and rotation bucket body inwall
Contact also matches with the inwall rotating bucket body.
Described rotary shaft is provided with stirring wing.
The beneficial effects of the utility model are:
The agitating device of this utility model design makes plastic pellet be in constantly flow regime, not only prevent plastic pellet resistance
Plug, more accelerates the falling speed of plastic pellet, and the setting that improve work efficiency, scraping blade or hairbrush makes plastic pellet not remain
On hopper inwall, the beneficially flowing of plastic pellet and whereabouts, it is simple to cleaning hopper inwall.
(4) accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described:
Fig. 1 is sectional structure schematic diagram of the present utility model.
In figure, 1 fixes bucket body, and 2 rotate bucket body, 3 hairbrush or scraping blade, 4 motors, 5 rotary shafts, 6 stirring wings.
(5) detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.As it is shown in figure 1, the hopper of this kind of extruder, including rounding
The body of platform shape, body is made up of the fixing bucket body 1 of outer layer and the rotation bucket body 2 of internal layer, fixing bucket body 1 and rotation bucket body 2 points
Not being slidably connected at upper and lower side, connect motor 4 in the upper end of fixing bucket body 1, the outfan of motor 4 down and connects rotary shaft 5,
Rotary shaft 5 is provided with stirring wing 6, and rotary shaft 5 lower end is connected with the lower end rotating bucket body 2, under the drive of motor 4, and rotary shaft 5
Bucket body 2 is rotated rotate together, is provided with hairbrush or scraping blade 3, hairbrush or scraping blade 3 in fixing bucket body 1 upper end and extends substantially downward to rotate
Bucket body 2 internal and with rotate bucket body 2 contact internal walls, the gradient of hairbrush or scraping blade 3 and the inwall kissing rotating bucket body 2 simultaneously
Closing, when rotating bucket body 2 and rotating, absorption is scraped off by hairbrush or scraping blade 3 at the plastic pellet rotating bucket body 2 inwall, rotates simultaneously
The part that axle 5 is connected with rotation bucket body 2 can also play stirring action, and coupling part can be two pieces of horizontal plates, it is also possible to
Be two pieces in splay connecting plate.
In order to make plastic pellet fall faster, it is also possible to stirring wing 6 changes into spiral helicine auger sheet, and the diameter of auger sheet is
Good up big and down small.
In addition to technical characteristic described in description, remaining technical characteristic is all known to a person skilled in the art technology.
