Description
Technical field
The utility model relates to the technical field of processing film equipment, more specifically, relates to a kind of amenities ventilated membrane secondary plasticizing one-step shaping process equipment.
Background technology
At present, the method for domestic production amenities ventilated membrane, after first calcium carbonate, PE pellet and auxiliary agent being mixed, after pelletizing production line granulation, then is put into the pellet made and cast film line is used for production amenities ventilated membrane.The deficiency of ventilated membrane adopting two-step method to produce has: (1) how granulating production equipment, need the electric energy of at substantial, during granulation, material is heated to 180 DEG C from normal temperature, be extruded into pellet, then pellet transported to another and to produce on amenities ventilated membrane production line and be heated to 240-250 DEG C from room temperature again and just can extrude and do film, be cooled to normal temperature could film forming, so, raw material are by post bake, and energy consumption is multiplied, because prilling complexity also can cause energy consumption to increase; (2) affect the quality of film, because raw material are post bake, its main performance index such as hot strength, percentage elongation declines; (3) in heating process, plastic melt is by means of only once filtering roughly, and screen pack load pressure is comparatively large, and draping frequency is higher; (4) adopt a plasticizing forming, can not produce the film of ultrathin type (15 grams/every square metre).
Summary of the invention
For solving the problems of the technologies described above, the technical scheme that the utility model provides is:
A kind of amenities ventilated membrane secondary plasticizing one-step shaping process equipment, comprises and plastifies equipment first: mixing facilities (1), net-changing device (2), the first measuring pump (3); Ventilated membrane production equipment: arranged die head (6), shaped device, stretching device and wrap-up successively, it is characterized in that, secondary plasticizing equipment is provided with successively: single screw extrusion machine (4), the second measuring pump (5) between described first measuring pump (3) and die head (6), melt first after plasticizing directly enters described single screw extrusion machine (4) and carries out secondary plasticizing under the pressure of the first measuring pump (3) advances, and the melt after secondary plasticizing enters described die head (6) under the pressure of the second measuring pump (5) advances.This kind of mode eliminates traditional granulation program, is that effectively improve product quality, the melt after secondary plasticizing, when controlled pressure appropriateness, can produce ultrathin film reducing energy consumption while.
Further, described mixing facilities (1) is parallel double-screw extruder.
Again further, between single screw extrusion machine (4) and the second measuring pump (5), be also connected with net-changing device, in order to impurity screening again, alleviate and once filter the excessive problem of the screen pack load pressure brought.
Again further, the inside of the first measuring pump (3) and the second measuring pump (5) is equipped with pressure sensor, and in order to detect the melt pressure of measuring pump porch, simultaneously pressure sensor is connected with each other formation pressure control device, to control melt pressure, make it to meet the needs producing ultrathin film.Compound is put on mixing facilities (1), become plastic melt, but melt pressure is now only 6-7Mpa, does not reach the melt pressure of the 8-10Mpa that article of manufacture needs far away after kneading, shearing, batch mixing plasticizing.Need to carry out boosting process by the first measuring pump 3, make the pressure of the plastic melt entering this measuring pump reach the normal pressure produced.; It is shaping that this plastic melt enters single screw extrusion machine (4) secondary plasticizing after boosting, then by the second measuring pump (5) by the pressure stability of plastic melt at about 15Mpa, the ultrathin film that thickness reaches 15 grams/m can be produced.
Compared with prior art, the utility model has the advantage of by secondary plasticizing shaping, save the energy consumption of pelletizing production line; Improve product quality; Reduce draping frequency; Produce the ultrathin film of 15 grams/m.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Mark in figure: 1, parallel double-screw extruder, 2, net-changing device, the 3, first measuring pump,
4, single screw extrusion machine, the 5, second measuring pump, 6, die head.
Detailed description of the invention
Accompanying drawing 1, only for exemplary illustration, can not be interpreted as the restriction to this patent; In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.Describe position relationship in accompanying drawing only for exemplary illustration, the restriction to this patent can not be interpreted as.
As shown in Figure 1, a kind of amenities ventilated membrane secondary plasticizing one-step shaping process equipment, comprises and plastifies equipment first: mixing facilities 1, net-changing device 2, first measuring pump 3; Ventilated membrane production equipment: arranged die head 6, shaped device, stretching device and wrap-up successively, it is characterized in that, is provided with secondary plasticizing equipment successively between described first measuring pump 3 and die head 6: single screw extrusion machine 4, second measuring pump 5.Melt first after plasticizing directly enters single screw extrusion machine 4 and carries out secondary plasticizing under the pressure of the first measuring pump 3 advances, and the melt after secondary plasticizing enters die head 6 under the pressure of the second measuring pump 5 advances.Mixing facilities 1 is preferably parallel double-screw extruder.
Operation principle: calcium carbonate, PE pellet and auxiliary agent are after batch mixer mixes, compound is put on parallel double-screw extruder 1, mediate through parallel double-screw extruder, shear, after mixing plasticizing, material melting in spiro rod machine tube fully plastifies into melt state, material after plastifying is after the impurity screening of net-changing device 2, first measuring pump 3 quantitative feeding and boosting, ensure plastic melt when voltage stabilizing and quantitative, directly enter single screw extrusion machine (4), save the operation of granulation, save pelletizing production line and produce the energy loss produced through granulation, raw-material loss and human cost loss, avoid the decline of the plastic material performance that resin secondary heating causes.Plastic melt carries out secondary plasticizing at single screw extrusion machine 4, and meanwhile, the second measuring pump 5 stablizes the pressure of plastic melt at about 15Mpa, make use of the technique that the secondary plasticizing of this single screw extrusion machine 4 is shaping, can produce ultrathin film.Through the plastic melt that single screw extrusion machine 4 plastifies, the second measuring pump 5 quantitative feeding and guarantee melt pressure, feed, to die head 6, is squeezed into ultrathin film, and thickness can reach 15 grams/m.
Meanwhile, the inside of the first measuring pump (3) and the second measuring pump (5) is equipped with pressure sensor, in order to detect the melt pressure of measuring pump porch, and the formation pressure control device that is connected with each other, to control melt pressure, make it to meet the needs producing ultrathin film.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
