Description
The utility model relates to filter screen, the net exchanging device in a kind of plastic molding equipment, drum type brake filter screen, net exchanging device in a kind of more precisely plastics extrusion blow molding machine.
At present, what adopt between the machine barrel discharge end of plastics extrusion blow molding machine and the head connector is tabular flow distribution plate and screen pack, so that the material of being extruded by screw rod becomes rectilinear motion by rotatablely moving, and stop impurity and the plasticizing material of getting well pass through, increase the materials flow back pressure, make plastic products more closely knit, flow distribution plate plays the effect of supporting screen pack in addition.This filter screen shunt filtering apparatus structure is simple, easily manufactured, and material is less by, the effective area that filters, and back pressure is higher to help material plasticizing and goods are closely knit though it produces, can the also corresponding extrusion capacity that reduces extruder, reduced output.More be unfavorable for using second-hand material and dose cheap; material is played the inorganic filling master batch of modifying function; because of using second-hand material and inorganic filling master batch very easily to cause impurity to stop up filter screen; need frequent draping; and each draping all will be shut down 6-8 flange bolt of dismounting; waste time and energy, reduced the output and the finished product rate of extruder, increased product energy consumption and cost.
Present more advanced filter screen quick replacement device, a kind of is the sliding hydraulic net-changing device, promotes filter screen that slide plate changes needs rapidly by the piston of hydraulic jack and releases and place new filter screen.Another kind is a dual channel screen replacing device, cuts off or open two runners respectively by the change in valve orientation, makes it rotate participation work, changes the filter screen of inoperative runner simultaneously.These two kinds of net-changing devices all can be finished the draping task very soon under the state of not shutting down, do not reduce extruded velocity.But its structure is all complicated, and the material of some part, machining accuracy, sealing requirements are higher, and the cost height is difficult for applying.And the flow distribution plate effective diameter still equates with the machine barrel internal diameter, and is effectively little by, filter area, reduced the extrusion capacity of extruder equally, reduced output.
The purpose of this utility model is to provide a kind of strainer filtering effective area to enlarge, and draping is drum type brake filter screen, net exchanging device rapidly.
Technical solution of the present utility model is as follows: the filter screen before the tabular flow distribution plate is removed, make flow distribution plate remove the effect of supporting filter screen from and only have the back pressure of increasing and become material and rotatablely move and be straight-line function.Dull and stereotyped flow distribution plate still squeezes and holds under the arm between machine barrel and movable doorboard, movable doorboard tightens the set connector, below dull and stereotyped flow distribution plate, be provided with drum type brake filter screen sleeve pipe and filter screen in the connector and divide flow cone, the feed end that divides flow cone to be connected in the filter screen sleeve pipe plays and shunts and the afflux effect, and filter screen is on the cylindric outer round surface that is enclosed within the filter screen sleeve pipe, be thick with aperture on the filter screen sleeve pipe circle wall, be beneficial to material and enter the filter screen set tube cavity.Discharge end is connected with the curved neck of discharging below the filter screen sleeve pipe, curved neck inner chamber communicates with the filter screen set tube cavity, below curved neck, be provided with the draping bolt that is fastened on the connector, be installed with the pulling bolt that is connected on the curved neck in the middle of the draping bolt, the discharging opening of corresponding curved neck inner chamber is provided with the head connector that is fastened on the connector, head connector inner chamber communicates with curved neck inner chamber, constitutes the material movement passage.For fastening movable doorboard and connector better, between movable doorboard and connector, be provided with alignment pin; In order to prevent that curved neck from rotating, and is provided with the anti-rotation key between curved neck and connector in connector.
The effective area of strainer filtering of the present utility model enlarges greatly, has overcome the bias current phenomenon of material in runner and has taken place, and draping is rapid, has improved single machine yield, greatly reduces product cost.
Accompanying drawing and drawing are described as follows:
Fig. 1 is the front section view of the utility model most preferred embodiment.
Among the figure: 1 dull and stereotyped flow distribution plate, 2 alignment pins, 3 movable doorboards, 4 linings, 5 fens flow cones, 6 connectors, 7 filter screen sleeve pipes, 8 anti-rotation keys, 9 curved necks, 10 draping bolts, 11 packing rings, 12 pulling bolts, 13 head connectors, 14 filter screens, 15 machine barrels.
Provide most preferred embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying the utility model.
With reference to figure 1, present embodiment is a preferred embodiment of the utility model.Remove being located at dull and stereotyped flow distribution plate 1 preceding filter screen, dull and stereotyped flow distribution plate 1 still squeezes and holds under the arm between machine barrel 15 and movable doorboard 3, is with the connector 6 of cavity on the movable doorboard 3 with screw threads for fastening one circle, and locatees with alignment pin 2.Be provided with lining 4 between connector 6 and the dull and stereotyped flow distribution plate 1, be provided with drum type brake filter screen sleeve pipe 7 and filter screen 14 and center in the connector 6 and divide flow cone 5, the center divides flow cone 5 to be threadedly connected to the feed end of filter screen sleeve pipe 7, play shunting and afflux effect, filter screen 14 is on the cylindric outer round surface that is enclosed within filter screen sleeve pipe 7, the effective area that filter screen 14 filters enlarges greatly, is thick with aperture on the round wall of filter screen sleeve pipe 7, and material passes filter screen 14 is entered filter screen sleeve pipe 7 by aperture inner chamber.Discharge end below the filter screen sleeve pipe 7 curved neck 9 of a discharging that is threaded, curved neck 9 inner chambers communicate with the inner chamber of filter screen sleeve pipe 7, and curved neck 9 is actively tied in the connector 6, and prevents rotation by anti-rotation key 8.Below curved neck 9, be provided with draping bolt 10, on connector 6, the discharging opening of corresponding curved neck 9 inner chambers is provided with head connector 13 with screw threads for fastening, also with screw threads for fastening on connector 6, head connector 13 inner chambers communicate with curved neck 9 inner chambers, constitute the material movement passage.Be installed with pulling bolt 12 in the middle of the draping bolt 10, pulling bolt 12 is connected on the curved neck 9 with left-hand thread, is lined with packing ring 11 between pulling bolt 12 and draping bolt 10.During extruder work, material is entered in the connector 6 through dull and stereotyped flow distribution plate 1 by machine barrel, divides flow cone 5 shuntings by the center, and the aperture on filter screen 14, filter screen sleeve pipe 7 circle walls enters the inner chamber of filter screen sleeve pipe 7, divide the inner chamber of flow cone 5 affluxs by the center again to curved neck 9, through head connector 13 inner chambers to head.
During draping, rotation draping bolt 10 just can be taken curved neck 9 out of by pulling bolt 12, thereby filter screen sleeve pipe 7, filter screen 14 and branch flow cone 5 are pulled out, and filter screen 14 is unloaded, and changes rapidly, has accelerated draping speed, has improved board output, fills CaCO
3The masterbatch ratio can be increased to 20%-25% by original 4%-5%, and when using second-hand material to produce, the ratio of dosing can increase to 50%-80%, greatly reduces product cost, has remarkable economic efficiency.
