Description
Technical field
The utility model relates to a kind of vertical blanking device of solid particle, relates in particular to a kind of feed arrangement of graininess plastics.
Background technology
Different shape particle is an insoluble technical problem in the graininess plastics-production.The existence of different shape particle has not only influenced the image appearance of plastic pellet product, the more important thing is, different shape particle itself is because himself structure has bigger performance difference with normal grain in process of production, thereby influence the processing use of downstream user.With the polyester bottles grade pet chip is example, different shape particle is in the solid-phase tack producing course of reaction, because its inner little molecule, diffuse to particle surface easily as acetaldehyde, moisture etc., carry out to the positive reaction direction thereby improved the reaction of its solid-phase tack producing, cause the inherent viscosity of finished product characteristic ratio of viscosities normal grain of different shape particle higher more.Carry out in the injection moulding bottle blowing process in downstream user, the high different shape particle of viscosity is difficult for being melted plasticizing, can produce brilliant point on the bottle germ wall, causes the generation of waste product bottle embryo.Different shape particle is prevalent in the various plastic processing industries, as spinning, membrane etc. the influence of processing and forming.
The common feed arrangement that is used for solid particle is mainly rotary feeder (also claiming rotary valve), single tube screw feeder and screw rod feed appliance etc. both at home and abroad, and these feed arrangements all can produce extruding to material particles inevitably, thereby form different shape particle.
At present, the most frequently used solid particle feed arrangement is a rotary feeder.The main cause that different shape particle produces is, the unbodied plastic grain of high temperature is in the process that enters into the crystallizing and drying device through rotary feeder, plastic grain is subjected to the extruding of rotary feeder rotating vane easily, because the degree of crystallinity of plastic grain is low, hardness is little, the temperature height is extruded distortion easily, produces different shape particle.Plastic pellet is subjected to the situation of the rotating vane extruding of rotary feeder, particularly it is outstanding when the production load surpasses the scope of design of rotary feeder inlet amount, therefore some producer reduces the quantity of different shape particle by the rotary feeder of changing bigger model, but can rise to some extent again in the quantity of the different shape particle in device lifting load back.
The utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of feed arrangement of graininess plastics, to avoid the generation of different shape particle.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of feed arrangement of graininess plastics, comprise main body feeding mechanism and governor motion, described governor motion comprises the adjustable plate of regulating main body feeding mechanism charging aperture sectional area, the stiff end of described adjustable plate is installed on the main body feeding mechanism, and the free end of described adjustable plate is arranged in the main body feeding mechanism charging aperture cross section.By regulating the state of adjustable plate in the main body feeding mechanism, the size that can regulate main body feeding mechanism cross section, and then the feed speed of control material.
Described main body feeding mechanism is provided with the spacing hole of restriction adjustable plate motion, described governor motion comprises adjustable column, described adjustable column comprises nut and double-screw bolt, described double-screw bolt is fixed on the main body feeding mechanism outside, described nut is installed on the double-screw bolt, the stiff end of described adjustable plate passes the spacing hole on the main body feeding mechanism, is installed on the nut.By the turn nut, the stiff end that can drive adjustable plate moves up and down, at this moment, spacing hole on the main body feeding mechanism becomes the fulcrum of adjustable plate, the free end of adjustable plate is followed the stiff end of adjustable plate and is done relevant motion, thereby can realize the adjusting of adjustable plate to main body feeding mechanism charging aperture cross-sectional sizes.
Described each adjustable plate is connected with two adjustable columns, and when avoiding adjustable plate only to be connected with an adjustable column, the issuable rotation of its free end moves up and down and it is only done.
The described main body feeding mechanism outside is provided with two supports parallel with the charging aperture cross section, and support is arranged on the both sides up and down of spacing hole, and the double-screw bolt two ends of described adjustable column are separately fixed on the support, and the nut of adjustable column is in the middle of two supports.
The preferred number of described adjustable plate is eight.
Described main body feeding mechanism inboard can be provided with burden-guiding cone, and described burden-guiding cone is arranged on the adjustable plate top.Burden-guiding cone can guarantee that the graininess plastics do not have delay in the feed arrangement internal flow, also can avoid the graininess plastics to enter in the governor motion simultaneously.
Described main body feeding mechanism is cylindrical steel drum.
Beneficial effect: the feed arrangement of the graininess plastics that the utility model provides, by straight feed pipe, avoided extruding to the high temperature amorphous granular, can not produce different shape particle; By the adjusting of adjustable plate to the charging aperture cross section, can guarantee the full packages charging, effectively isolate the air crossfire of former and later two systems of feed arrangement, stablized the process conditions of system; And can easily regulate the inlet amount of granular particles, satisfy the lifting of device production load to greatest extent, help the reduction of production cost according to the production capacity of process units.
