Abstract
The invention relates to a plastic granulation machine die head which comprises a casing (6), a feeding port (1), a discharging port (5) and a filter screen (2). The Plastic granulation machine die head is characterized in that a retaining plate (4) capable of swinging from side to side is connected with the inner side of the casing, and the inner side of the casing is connected with the retaining plate through a connecting device (3). During a changing process of the filter screen of the plastic granulation machine die head, the retaining plate rotates to a cavity where the filter screen is changed and blocks the cavity, plastic melt can not flow back to the cavity from a gap, production efficiency is improved, and cost is reduced.
Description
Technical field
The present invention relates to a kind of comminutor die head, especially a kind of plastic granulator die head.
Background technology
Plastic granulator is used in plastics recovery and reprocessing industry widely, the plastic granulator that uses at present, and its die head is generally two chambeies; Filter screen all is equipped with at its outlet position; In process of production, use a few minutes promptly can stop up, must change filter screen then.In the process of changing filter screen, generally be the chamber of cutting off needs replacing filter screen wherein, change its filter screen; But in the process of changing; Former filter screen place can produce the space, is not also working owing to change the chamber of filter screen, and the pressure that plastic melt produces enables plastic melt and from the space, is back to the chamber of changing filter screen; Make production efficiency reduce, cost increases.
Also do not have at present invention can overcome the plastic granulator die head in the process of changing filter screen, plastic melt is back to the problem in the chamber of changing filter screen from the space that the replacing filter screen stays.
Summary of the invention
In order to overcome existing plastic granulator die head in the process of changing filter screen, plastic melt is back to the chamber of changing filter screen from the space, makes production efficiency reduce, the shortcoming that cost increases, and the present invention provides a kind of plastic granulator die head.
The technical solution adopted for the present invention to solve the technical problems is: a kind of plastic granulator die head, comprise shell (6), charging aperture (1), discharging opening (5), filter screen (2), and it is characterized in that: the shell inboard is connected with the baffle plate (4) that can swing; Lean on jockey (3) to be connected between shell inboard and the baffle plate; Described jockey comprises hinge, pin, bolt; The shape in baffle plate cross section comprises zhou duicheng tuxing and non-zhou duicheng tuxing; The described zhou duicheng tuxing of baffle plate cross sectional shape comprises herringbone, fan-shaped, fishtail, triangle; Baffle plate pivot distance on two summits to about the baffle plate is not less than the inboard vertical range of shell left back two; The shape of discharging opening comprises circle, square, triangle, polygon; This die head scope of application comprises single screw pelletizer, dual-screw pelletizer; Charging aperture quantity is at least two; Filter screen is detachable.
The invention has the beneficial effects as follows: the plastic granulator die head can not make plastic melt from the space, be back to the chamber of changing filter screen, thereby enhance productivity in the process of changing filter screen, reduces cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of conventional plastic comminutor die head.
Fig. 2 is the discharging sketch map of conventional plastic comminutor die head.
Fig. 3 is a structural representation of the present invention.
Discharging sketch map when Fig. 4 is draping of the present invention.
Among Fig. 1-Fig. 4,1. charging aperture, 2. filter screen, 3. jockey, 4. baffle plate, 5. discharging opening, 6. shell.
The specific embodiment
In Fig. 1-Fig. 4, plastic melt gets in two chambeies of die head from two charging apertures (1) respectively, and under the normal condition, plastic melt finally is extruded the plastics that form definite shape again through screen pack (2) and discharging opening (5).Stop up at filter screen (2), when needing to change, cut off the chamber that needs to change filter screen; Cut off the supply of plastic melt; This moment, the pressure that plastic melt produces made baffle plate (4) rotate to the direction in the chamber of cutting off around jockey (3) because another chamber operate as normal, because baffle plate (4) pivot distance on two summits to about the baffle plate is not less than the inboard vertical range of shell left back two; So the chamber of cutting off is blocked by baffle plate (4), plastic melt can not be back in the chamber of cutting off.After filter screen (2) replacing finishes, open the chamber of cutting off, recover the supply of plastic melt, after plastic melt gets into the chamber, make the pressure in two chambeies equate that baffle plate (4) recenters once more.
