Abstract
The utility model is related to a kind of improved hot-cut pelletizers extrusion dies.It includes spreader, and the streamlined structure chamfering of no dead angle and stagnant wake is set as in the feed end oral area of the material extrusion hole of extrusion die；The feed end that material extrusion hole is arranged is big, and discharge end is small, and the gradient pattern draft at 13 degree is arranged from feed end to discharge end；Keep charging circulation without hindrance, discharging speed is uniform.The utility model can make material be full of and can uniformly squeeze out along the runner of head, while material being avoided to thermally decompose.
Description
Technical field
The utility model is related to a kind of rubber and plastic processing equipment mold, especially a kind of improved hot-cut pelletizers head die
Tool.
Background technology
Currently, well known fervent extruding granulator, the polymer of melting is from hot die extrusion, the rotation that is rotated against die face
Rotor is cut into particle.The characteristic of this sweet grain system is the water spray pelletizing room of its special designing.Water helically line around because flowing, directly
To the sweet grain room of outflow.After particle is cut, that is, lower flow is thrown, preliminary quenching is carried out.Moisture is removed subsequently into centrifugal dryer.
It is earnestly being granulated in production technology, pellet head carries the task of extrusion of wire, while also being used as pelletizing mold.Design
To meet many requirements when head, not required also not according to the purposes difference of head.The disadvantage is that：Due to head internal pressure
The material flow difference that deficiency is flowed out from hole frequently results in the particle length cut out and differs, and particle is not full.
Utility model content
The goal of the invention of the utility model provides a kind of improved hot-cut pelletizers machine aiming at the defect of existing product
Head mould has, and material can be enable to be full of and can uniformly squeeze out along the runner of head, while material being avoided to thermally decompose.
What the technical solution of the utility model was realized in：A kind of improved hot-cut pelletizers head die of the utility model
Tool comprising spreader, it is characterised in that：The feed end oral area of the material extrusion hole of extrusion die is set as no dead angle and stagnant wake
Streamlined structure chamfering；The feed end that material extrusion hole is arranged is big, and discharge end is small, and setting is gradient in 1-3 from feed end to discharge end
The pattern draft of degree；Keep charging circulation without hindrance, discharging speed is uniform.
The inner wall polishing of further material extrusion hole is set as shiny surface.
The beneficial effects of the utility model are that the utility model is simple in structure, easy to use, more reasonable more section after improvement
It learns, original head inner cavity is not provided with chamfering or chamfering is insufficient, and pressure is inadequate, so that material is full of inner cavity from perfection, causes
Discharging is uneven, is now improved to head inner cavity 3, forms it into streamlined chamfering, removal dead angle and stagnant wake etc. is local, convection current
Road carries out smooth processing, and material can uniformly be squeezed out from discharge hole 2.It solves the runner that material is completely filled with head well
And the problem of changing the uniformity of each hole flow velocity.The speed that material is flowed out from each discharge hole of head is identical, and pelletizing is made to reach size
Unanimously, fuller effect compensates for the deficiency of existing product.
Description of the drawings
Fig. 1 is the front schematic view of the utility model embodiment.
Fig. 2 is the sectional view along A-A of the utility model embodiment Fig. 1.
In figure：1, spreader, 2, material extrusion hole, 2-1 charging port chamferings.
Specific implementation mode
The utility model is further described below in conjunction with attached drawing：The utility model embodiment one as shown in attached drawing 1,2
The improved hot-cut pelletizers extrusion die of kind comprising spreader 1, the material extrusion hole 2 being located on head grinding tool, in extrusion die
The feed end oral area of material extrusion hole 2 is set as the streamlined structure chamfering 2-1 of no dead angle and stagnant wake, keeps circulation without hindrance, discharging
Speed is uniform；The feed end that material extrusion hole 2 is arranged is big, and discharge end is small, and gradient pulling out in 1-3 degree is arranged from feed end to discharge end
Mould gradient.The inner wall polishing of material extrusion hole 2 is set as shiny surface.
The utility model is compared with original technology：Original head inner cavity chamfering is insufficient, and pressure is inadequate, prevents material from complete
U.S. is full of inner cavity, causes discharging uneven, is now improved, forms it into streamlined to the feed end of material extrusion hole 2 (head inner cavity)
Chamfering, removal dead angle and stagnant wake etc. is local, carries out smooth processing to runner, material can uniformly be squeezed out from material extrusion hole 2.
Claims (2)
