Abstract
The utility model discloses an extruder die head part, including the die head, its characterized in that: the control by throttling device is connected to the feed inlet of die head, and the control by throttling device includes valve body and throttle valve shaft, is equipped with throttling passage in the valve body, the feed cylinder discharge gate of throttling passage's import intercommunication extruder, and the feed inlet of throttling passage's export intercommunication die head, throttling passage's export has a heterotypic die cavity structure, the throttle valve shaft is adjustable to be established in throttling passage. The utility model discloses the plastic melt that enables to get into the die head feed inlet mixes more evenly to reach better plastify effect, improve the quality of the plastic products of making.
Description
[technical field]
The utility model relates to a kind of plastic extruder, is specifically related to a kind of part of the die head of plastic extruder.
[background technology]
Plastic extruder is extensively employed in plastic industry, its operation principle is: plastic pellet is added in extruder barrel, under the heat effect of the heating tube of barrel outside winding, plastic pellet in barrel becomes plastic melt, then rotate the effect of the thrust produced at extruder screw under, plastic melt flows out from the discharging opening of barrel, directly enters into die head subsequently and extrudes.In above process, plastic melting is known from experience existence part and is mixed non-uniform phenomenon, and plasticizing effect is bad, consequently may cause the quality existence defect in various degree of made plastic products.
[summary of the invention]
In view of the deficiency that prior art exists, the purpose of this utility model is to provide a kind of plastic melt that can make to enter die inlet to mix more even, thus reach better plasticizing effect, improves the extruder die head member of made plastic products quality.
The utility model takes following technical scheme:
Extruder die head member, comprise die head, it is characterized in that: the charging aperture connecting joint flow modulation device of described die head, throttle regulator comprises valve body and throttle valve lever, throttling passage is provided with, the barrel discharging opening of the inlet communication extruder of throttling passage, the charging aperture of the outlet die head of throttling passage in valve body, the outlet of throttling passage has heterotypic die space structure, and described throttle valve lever is adjustable to be located in throttling passage.
Described throttle valve lever is fixedly connected with adjusting screw(rod), and the adjusting nut mated with adjusting screw(rod) is fixed on valve body, and adjusting screw(rod) is connected with handwheel.
After adopting technique scheme, the plastic melt entering die inlet must first could be extruded from die head through the throttling passage of valve body, in the throttling passage of valve body, due to the flow restriction control effect of throttle valve lever, the outlet of throttling passage can be made to diminish, certain pressure will be produced like this to the plastic melt of coming from extruder barrel discharging opening, plastic melt is made in throttling passage, to be subject to certain pressure and to make it fully mix, thus reach better plasticizing effect, improve the quality of made plastic products.
[accompanying drawing explanation]
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model
[detailed description of the invention]
As shown in the figure, extruder die head member of the present utility model, comprise die head 10, the charging aperture 9 connecting joint flow modulation device of described die head 10, throttle regulator comprises valve body 7 and throttle valve lever 4, throttling passage 6 is provided with in valve body 7, the import 8 of throttling passage 6 is communicated with the barrel discharging opening of extruder, the outlet 5 of throttling passage 6 is communicated with the charging aperture 9 of die head, the outlet 5 of throttling passage has heterotypic die space structure, described throttle valve lever 4 is adjustable to be located in throttling passage 6, described throttle valve lever 4 is fixedly connected with adjusting screw(rod) 2, the adjusting nut 3 mated with adjusting screw(rod) 2 is fixed on valve body 7, adjusting screw(rod) 2 is connected with handwheel 1.When rotation handwheel, throttle valve lever just can do the movement of left and right directions in throttling passage, the outlet size of throttling passage is regulated, certain pressure will be produced like this to the plastic melt of coming from extruder barrel discharging opening, plastic melt is fully mixed in throttling passage, thus reach better plasticizing effect, improve the quality of made plastic products.
Claims (2)
