The structure of Fig. 2 and Fig. 3 is the same, and difference only is that variation has taken place the relative position of same spiral groove 2 on the circumferential surface of active toothed disk 1, and this is that characteristic by spiral groove 2 is determined.
As shown in Figure 1, the acute angle angle angle of the central axis of the plane at the radial centre lines place of spiral groove 2 and active toothed disk 1 is 42 °.The acute angle angle of the plane at spiral groove 2 places and the central axis of active toothed disk 1 is commonly referred to as helical angle, the helical angle of the feeding groove on the feeding spiro rod similarly is generally 15 °---and 20 °, the helical angle of spiral groove of the present utility model is greater than the helical angle of feeding groove on the feeding spiro rod, can realize material is produced the more effect of high thrust, this bigger thrust helps material on the one hand the passing through smoothly of this section of fluted disc group passage, also helps material on the other hand and shears more fully, disperses and mix between active toothed disk and quiet fluted disc.
In actual applications, the quantity of spiral groove 2 can be 8---14, using maximum is 10---and 14, so following quantity that provides spiral groove 2 is 10---14 example:
As shown in Figure 3, the quantity of spiral groove 2 is 10, is distributed in the circumferential surface of active toothed disk equably.
As shown in Figure 4, the quantity of spiral groove 2 is 11, is distributed in the circumferential surface of active toothed disk equably.
As shown in Figure 5, the quantity of spiral groove 2 is 12, is distributed in the circumferential surface of active toothed disk equably.
As shown in Figure 6, the quantity of spiral groove 2 is 13, is distributed in the circumferential surface of active toothed disk equably.
As shown in Figure 7, the quantity of spiral groove 2 is 14, is distributed in the circumferential surface of active toothed disk equably.
Within the specific limits, the quantity of spiral groove 2 is many more, and is just good more to shearing, dispersion and the mixed effect of material.Certainly, the size of the quantity of spiral groove 2 and material particles should adapt.
As Fig. 1---Fig. 7 and shown in Figure 9, in actual applications, the centre bore fixed jacket of active toothed disk 1 is on the central shaft 8 of single screw rod 12, active toothed disk 1 can rotate along with the rotation of single screw rod 12, the centre bore of the quiet fluted disc 7 then central shaft 8 than single screw rod 12 is big, and quiet fluted disc 7 is transfixion at any time; Active toothed disk 1 and the quiet fluted disc 7 common fluted disc groups of forming utilize the relative motion that forms between active toothed disk 1 and the quiet fluted disc 7 and corresponding material channel mutually, make the fluted disc group shear, disperse and mix material in the transmission material.
As shown in Figure 9, single screw rod 12 places in the charging line 4, the circumferential outer surface of single screw rod 12 is provided with spiral feeding groove 6, material places in the feeding groove 6, when single screw rod 12 rotates, the sidewall 5 of feeding groove 6 can be given extruding force of material, can produce a motive force forward to material after this extruding force is decomposed, and promotes material and advances.With Fig. 9 is example, if the clockwise direction that single screw rod 12 is looked with the right side is a direction of rotation, then single screw rod 12 can promote material and advance from left to right; If the counter clockwise direction that single screw rod 12 is looked with the right side is a direction of rotation, then single screw rod 12 can promote material and advance from right to left.
As shown in Figure 9, active toothed disk 1 described in the utility model and quiet fluted disc 7 common several fluted disc groups of forming are installed on the centre of single screw rod 12.In conjunction with Fig. 1---Fig. 7 and Fig. 9, when material during, at first pass through the spiral groove 2 of active toothed disk 1 by the fluted disc group, be pushed to port by spiral groove 2 brute forces, and enter in the space between active toothed disk 1 and the quiet fluted disc 7 near quiet fluted disc 7.Under the relative rotary motion of active toothed disk 1 and quiet fluted disc 7, material is sheared, disperses and mix in the space between active toothed disk 1 and the quiet fluted disc 7, under the effect of motive force, enter simultaneously the space of quiet fluted disc 7 opposite sides by the material channel of quiet fluted disc 7, in this space, sheared once more, disperseed and mixed, enter the spiral groove 2 of second active toothed disk 1 then again, be pushed to by spiral groove 2 brute forces in the feeding groove 6 of single screw rod 12, up to being sent to next fluted disc group, carry out with last identical by the process of twice shearing, dispersion and mixing.Material is in the process by above-mentioned each fluted disc group, only in the space of quiet fluted disc 7 both sides and the material channel in the quiet fluted disc 7, form resistance, but this resistance itself is less, and offset by the strong motive force of spiral groove 2, so thoroughly solved the bigger problem of fluted disc group resistance of existing tandem mill single screw extrusion machine.
As shown in Figure 9, in order to reach best effect, generally at a little less active toothed disk 1 (because bigger) of the quantity that adopts spiral groove 2 near the place of arrival end, at the more active toothed disk 1 (because less after shearing) of the quantity that adopts spiral groove 2 near the place of the port of export through multiple sets of teeth dish group near the material particles of the port of export near the material particles of arrival end.
In conjunction with above-mentioned tandem mill single screw extrusion machine operation principle, in conjunction with Fig. 8 and Fig. 9 progressive part of the present utility model is described again, Figure 8 shows that the right view of traditional active toothed disk 10, its feeding channel is clear opening 9 radially.Suppose that as shown in Figure 9, centre bore 11 fixed jackets of active toothed disk 10 are on the central shaft 8 of single screw rod 12 during application with the active toothed disk 1 in active toothed disk 10 alternate figures 9.In active toothed disk 10 rotary courses, radially clear opening 9 can not produce thrust to the material in it, so the feeding power of material in the clear opening 9 of active toothed disk 10 comes from the motive force of single screw rod 12 fully, so material forms a bigger resistance in the clear opening 9 of active toothed disk 10, this resistance can consume the motive force of single screw rod 12, and the moment of torsion of single screw rod 12 is increased, and load increases, cause the torsional deformation of single screw rod 12 and element thereof easily, even damage; The also corresponding step-down of extrusion capacity of while material, speed is slack-off, and head pressure also can reduce, and makes check rod also relatively more difficult; In addition because the extruding force of material in the space of quiet fluted disc 7 both sides is less, so the effect of shearing, dispersion and mixing between active toothed disk 10 and quiet fluted disc 7 also can be had a greatly reduced quality.
