Fig. 2 is the utility model structural representation top view.
Structural representation when Fig. 3 is the utility model work.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further details.
By Fig. 1 to Fig. 3, provided, the utility model comprises net-changing device main body, 1 li of net-changing device main body has discharging chamber 2 and horizontal chute 3 longitudinally, there is heating tube 5 net-changing device main body 1 inside, there is the recoil feed bin 6 that is placed in 2 both sides, discharging chamber net-changing device main body 1 inside, air bleeding valve 7 is equipped with at net-changing device main body 1 two ends, left and right, air bleeding valve 7 communicates with recoil feed bin 6, recoil feed bin 6 is connected with discharging chamber 2 and chute 3, net-changing device main body 1 upper end is fixed with recoil oil cylinder 8, on recoil oil cylinder 8, there are two recoil plungers 9, recoil plunger 9 is connected with the feed bin 11 that rushes of net-changing device main body 1 inside through plunger gland 10, net-changing device main body 1 right-hand member is fixed with work master cylinder 12 through support bolt 16, on work master cylinder 12, reciprocating slide board 13 is housed, on reciprocating slide board 13, there are four working positions 14, on four working positions 14, filter screen 17 is all housed, reciprocating slide board 13 is contained in the chute 3 of net-changing device main body 1.
In order to guarantee result of use, on the filter screen 17 of said working position 14, pressure network inserts 15 is housed.
Said four working positions 14 are from left to right the first working position, the second working position, the 3rd working position and the 4th working position successively.
The interior the right and left of said net-changing device main body 1 has entrance point 4, and entrance point is connected with chute 3.
Operation principle of the present utility model is:
Duty: double back wash plug is in pressing down micro-material hole and the recoil hole of drawing of position sealing recoil feed bin, and the feed bin that makes to recoil disconnects with work sprue.
Draping state: after work certain hour, the filter screen 17 of the first working position stops up to be with while to a certain degree needing to carry out draping, and pressure tester can be pointed out with sound and light alarm form (presetting best draping pressure spot).At this moment start and treat that working end recoil oil cylinder 8 pulls recoil plunger 9 to draw material, make clean material enter this Position Design of recoil feed bin 6(and have fine tuning structure, make it at the micro-material state that draws of the best, draw material), the gas entering in the material melt compressing recoil feed bin 6 of recoil feed bin 6 is discharged from air bleeding valve 7, when air scavenge is closed air bleeding valve 7 after thoroughly.Now start the net of washing that recoil oil cylinder 8 buttons carry out the second working position filter screen, the impurity being attached on filter screen is discharged from entrance point 4 after the power recoil of the recoil oil cylinder Final 8.Then start work master cylinder 12 and promote (or retracting) reciprocating slide board 13, complete recoil, at this moment can change the filter screen of the 3rd working position and the 3rd working position.Other working position work are identical therewith.
Note: this back flushing process is filled type recoil, its distinguishing feature is that before and after the porous plate after recoil, groove is enriched by new material, back flushing process is also to draw material exhaust process, is designed with in addition the auxiliary material exhaust structure that draws, and can draw material exhaust according to producing actual assisting.
The utility model is suitable for material: the plastic melts such as PP PE PS EPE EPS PVB BOPET/BOPP chemical fiber
The utility model appropriate products: granulation, wire drawing, spray silk, tubing, sheet material, sheet material, the goods such as hollow sheeting.
The utility model structural design advantage: the reciprocating design of four stations, increases the penetrating rate of runner, the ripple disable of material stream relatively during the sprue of slide plate footpath; Material design is drawn in fine setting, and accurately drawing material does not affect major ingredient stream; Two-chamber isolation independent back flushing, material is pressed ripple disable; Filled type recoil, exhaust integratedization that recoil, reduces recoil material.
The utility model control system: the draping of this structure and backwash net action can divide manual pushbutton operation and PLC to control automatic operation, for user's choice for use.
The utility model handling characteristics: powerful ripple disable filled type backwash net, the stability of raising product; Net sheet repeatedly rinses use, reduces costs, and enhances productivity; Filter screen preheats and draws material exhaust structure and guarantees product quality; Short runner design is stablized material back pressure, reduce material aging with degraded.
The utility model structure is ingenious, and manufacturing process is simple, easy to use, can effectively solve plastic product and in extruding continuous flow procedure, not shut down draping automatically, can not wash online the problem of net.
