Abstract
The utility model relates to a die head device which belongs to the field of plastic production. The die head device of an extruder comprises a die head body (1) and a row of through holes which are arranged in the middle of the die head body (1) and go through the die head body (1); each through hole comprises a die head feed opening (2) and a communicated die head discharge hole (3); the die head device is characterized in that the die head discharge hole (3) is in a trumpet end shape, one end connected with the die head feed opening (2) has smaller diameter, and the other end has bigger diameter. When plastics is changed into strips and passes through, the changed die head device not only ensures the required diameter of the discharged strips and meets the function requirements, but also reduces the impact of temperature on the materials and the formation of dregs, prevents the dregs from remaining at the discharge hole and affecting the follow-up strips, ensures the appearance quality of the discharged strips, and improves the quality of plastic particles.
Description
Technical field
The utility model relates to a kind of die head, relates in particular to a kind of plastics and extrudes the die head device that is used for the cold granulation of tie rod in the production.
Background technology
Extrude in the production at plastics, die head device is indispensable part.What accompanying drawing 1 and Fig. 2 provided is that present plastics are extruded die head device structural representation and the A-A profile that generally uses in the production, die head device comprises a plurality of through holes that pass die body of a row of die body and die body central authorities, through hole comprises the cylindrical discharging opening of charging aperture and connection, and die head device is inside and outside for extruding preceding plastics and extruding back plastics material bar.The material of fusion enters die head by the charging aperture of die head, forms many material bars from discharging opening, and the material bar of bunchy carries out pelletizing again through tie rod, tank cooling, air-dry, obtains plastic pellet.The die head discharging opening is that length is the cylindrical of 10mm-30mm, plastic pellet diameter after the pelletizing and die head discharging opening equal diameters.
Yet in actual production, find a phenomenon, because the die head discharging opening is cylindrical, will by the time material bar outer ring coat fully, and because material is extruded during by die head, temperature becomes low temperature from high temperature again when coming out, therefore after long-time production, die head discharging opening place will produce a lot of dregs, has influence on the follow-up plastic pellet outward appearance of passing through.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of extruder die head device, solves prior art die head discharging opening place and can produce a lot of dregs, influences the defective of plastic pellet exterior quality.
Technical scheme
A kind of extruder die head device, the a plurality of through holes that pass die body 1 of a row that comprise die body 1 and die body 1 central authorities, through hole comprises die inlet 2 and the die head discharging opening 3 that is communicated with, it is characterized in that: described die head discharging opening 3 is bell mouth shape, an end diameter that links to each other with die inlet 2 is little, and other end diameter is big.
Beneficial effect
Die head device after the utility model changes is when plastics become the material bar and pass through, both guaranteed the due diameter of discharging bar, reached functional requirement, reduce the influence of temperature again to material, reducing dregs forms, and reduce dregs and rest on discharging opening and make follow-up material bar influenced, guaranteed the exterior quality of discharging bar, improved the quality of plastic pellet.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
A kind of extruder die head device, it is a kind of improvement to the congenerous device that generally uses now.Concrete structure is: the material of fusion enters in the die body 1 by die inlet 2 in the extruder, forms many material bars from die head discharging opening 3, and the material bar of bunchy carries out pelletizing again through tie rod, tank cooling, air-dry, obtains plastic pellet.
Described die head discharging opening 3 is bell mouth shape, and an end diameter that links to each other with die inlet 2 is little, and other end diameter is big.The material bar is after the 3 smaller diameter end moulding of die head discharging opening, because other end diameter is big, the material bar can not coated, and reduces the influence of temperature to material, reduces dregs and forms.
The utility model die head device, simple in structure, the die head discharging opening 3 of die body 1 one sides is bell mouth shape, the material bar can not coated, reduce the influence of temperature, reduce dregs and form material, even and formed dregs, also can reduce dregs and rest on discharging opening and make follow-up material bar influenced, guarantee the exterior quality of discharging bar, plastic pellet presentation quality stable had obvious effect.
Claims (1)
1. extruder die head device, the a plurality of through holes that pass die body (1) of a row that comprise die body (1) and die body (1) central authorities, through hole comprises die inlet (2) and the die head discharging opening (3) that is communicated with, it is characterized in that: described die head discharging opening (3) is bell mouth shape, an end diameter that links to each other with die inlet (2) is little, and other end diameter is big.
