Protection scope of the present invention.
The screw device 1 is single screw rod or twin-screw, and wherein single screw rod is that N roots screw rod concatenation is formed and in every two spiral shells
The junction of bar and correspond to discharging opening 4-1 and feedback outlet 4-2 the split single screw rod for being interval with dividing plate 31 or a screw rod
It is installed on the screw rod by disjunctor single screw rod and the dividing plate 31 that dividing plate 31 is divided into N sections, the installation site of dividing plate 31 corresponds to
The positive integer at the interval of discharging opening 4-1 and feedback outlet 4-2, wherein N >=2.The dividing plate 31 is in annular, is set in the company of screw rod
Connect in place, in the case of the mechanical connection between not influenceing screw rod, play a part of to block the circulation of material, make material from big gun
The discharging opening 4-1 outflows that cylinder 2 is provided with, after the filtering of sieves head, material is flow in gun barrel 2 from feedback outlet 4-2 again, finally
Next process is delivered to through screw device 1；When for disjunctor single screw rod, a screw rod is divided into can be connected with each other together
Multi-segmental, the dividing plate 31 is set with each two sections junction.
The split single screw rod needs that 2,3,4 or other positive integer root strings more than 2 can be selected according to production
Connect and form, in the present embodiment, the split single screw rod is preferably formed by the screw rod concatenation of 2 or 3；And disjunctor single screw rod is one
Screw rod is divided into 2 sections, 3 sections, 4 sections or other positive integer sections more than 2, in the present embodiment, preferably 2 to 4 sections by dividing plate 31.
The twin-screw is be arranged in parallel and is mutually twisted by two component body single screw rods or two groups of disjunctor single screw rods in equidirectional
Setting is formed.
Further, above-mentioned screw device 1 can rotate forward screw thread discharging or reversion screw thread discharging, i.e. single screw rod and double spiral shells
Bar can rotate forward screw thread discharging, or reversion screw thread discharging.The simple structure of single screw rod, low cost, and twin-screw
Mixing speed is fast and abundant, but high cost.
The gun barrel 2 used cooperatively with single, double screw rod, is provided with least one set of filter bores on gun barrel 2, the group number of filter bores can
To be any group of number, preferably 1~4 group, homonymy spread configuration or it is symmetricly set on gun barrel 2, wherein every group of filter bores are by same
A discharging opening 4-1 and feedback outlet 4-2 composition of the direction interval on gun barrel 2.
On the gun barrel 2 in charging aperture 3 and near between the discharging opening 4-1 of charging aperture 3 in the top of gun barrel 2 row of offering
Gas port 5, the exhaust outlet 5 is used to the pressure balance in the moisture discharge that will contain in material or holding gun barrel 2.Particularly use
In must be provided with exhaust outlet on the gun barrel 2 of production plastic product, and when the semi-finished product of plastics are produced, it is not necessarily required to the row of setting
Gas port 5.
The sieves head plays a part of cleaning, filtering to the impurity, the dust that contain in filtering plastic material, and
Available sieves header structure is various, and one of which sieves head includes sieve overcoat 7 and is provided with the circle sieve 6 long of opening, institute
State sieve overcoat 7 and be provided with one end of feed cavity 7-1, the feed cavity 7-1 in the horizontal direction by lath 7-2 and discharging opening 4-1 companies
Connect, the lower section of the feed cavity 7-1 other ends is connected by lath 7-2 with feedback outlet 4-2；Sieve overcoat 7 and lath 7-2 are integrally formed.
The circle sieve 6 long is sheathed in feed cavity 7-1 and has difference in height, set difference in height with the both sides inwall of feed cavity 7-1
It is easy for being flowed into circle sieve 6 long into the material in feed cavity 7-1 and carries out filtration.The concrete structure of the circle sieve 6 long can
To be：6 ends of circle sieve long are taper and are circumferentially with material leakage sieve aperture, the hollow sieve nest in screw-like, only needed when it is used by
Screen cloth is installed on circle sieve 6 long, can be rotated in a circumferential direction when it is used 360 degree, is filtered cleaner.This kind of sieves head needs are right
Title is used, and could be realized not shutting down and be changed screen cloth, the purpose that equipment continuously works.I.e. one work of sieves head, another filtering
Sieve head can carry out draping work, but two sieves heads can also work simultaneously when draping is not needed.This kind of sieves head
Can be used cooperatively with the sieves head of other structures, itself and gun barrel 2, a kind of assembling assumption diagram such as Fig. 8 institutes of screw device 1
Show；
Further, the structure of the sieves head can also be including sieve overcoat 7 and circle plansifter 11, the sieve overcoat 7
The lower end for being provided with feed cavity 7-1, the feed cavity 7-1 wide at the top and narrow at the bottom in vertical direction is connected by lath 7-2 and discharging opening 4-1
Connect, the side of feed cavity 7-1 upper ends is connected by lath 7-2 with feedback outlet 4-2；Sieve overcoat 7 and lath the 7-2 one into
Type.The round plansifter 11 is sheathed in feed cavity 7-1 by sieve first 10 and has difference in height with the bottom interior wall of feed cavity 7-1,
Set difference in height is specially：The sieve headgear lower end being connected with sieve first 10 is stepped, when sieve headgear is installed on feed cavity 7-1
When, sieving has material passage gaps between the bottom of headgear and the inwall of feed cavity 7-1 bottoms.The round plansifter 11 can realize level
Filtering of the direction to material, its filtration time is short, filtering is fast.This kind of sieves head needs symmetrically to use, and could so realize not
Screen cloth is changed in shutdown, the purpose of the continuous work of equipment, and it is as shown in Figure 9 with a kind of assembling assumption diagram of gun barrel 2, screw device 1.
Except being rotated using driver drives circle sieve 6 long and circle plansifter 11 when sieves head as shown in Figure 8, Figure 9 is used
Outward, the control device for controlling filter bores to open and close is also equipped with, its structure is as shown in Figure 10.The control device includes handle
9 and through lath 7-2, the plug flitch 8 above discharging opening 4-1 and feedback outlet 4-2, handle 9 is connected with one end of plug flitch 8,
