A kind of extrusion molding apparatus for plastic material
Technical field
The utility model relates to mechanical device fields, and in particular to a kind of extrusion molding apparatus for plastic material.
Background technique
In the extrusion molding stage of plastic cement, often will appear the imperfect situation of levelability of extruded stock after mixing kneading,
And then influence the subsequent sulfidation of extruded stock.
Utility model content
The purpose of this utility model provides a kind of extrusion molding apparatus for plastic material aiming at drawbacks described above.
A kind of extrusion molding apparatus for plastic material comprising two motors and two decelerations are arranged on chassis in chassis
Machine, the charging interface being arranged in above chassis are arranged on chassis and are connected to the packing cylinder of charging orifice, with packing cylinder
Cylindric material extrusion outlet and cutting part;
One end of the packing cylinder is equipped with the material extrusion twin-screw connecting with speed reducer, the other end and cylindric material extrusion outlet and connects
Logical, material extrusion twin-screw includes the two screw rods that setting and diameter gradually successively decrease diagonally downward, and the upper end of two screw rods is slowed down with two respectively
The output axis connection of machine, lower end protrude into cylindric material extrusion outlet, are equipped with one along its diametrical direction in cylindric material extrusion outlet and erect
Straight demarcation plate, the length of vertical separating plate is less than the length of cylindric material extrusion outlet and cylindric material extrusion is exported close to packing cylinder
One end is equipped with the space for accommodating two screw rods end, is in contact two screw rods not with vertical separating plate;The cutting part setting exists
On front side of cylindric material extrusion outlet discharge end, the cutting part include be arranged in chassis side an otic placode and with otic placode is hinged cuts
Cutting blade.
The cutting blade is arranged perpendicular to the extrusion direction of extruded stock.
It is located on front side of cutting part on the chassis and is additionally provided with recessed portion, multiple groups rotatingcylindrical drum is provided in recessed portion,
Height locating for rotatingcylindrical drum top is identical as the height on chassis surface.
The utility model advantage is: being squeezed into the plastic material after mixing to vertical separating plate by material extrusion twin-screw
Cylindric material extrusion outlet in so that extruded stock prolong its diametrical direction be divided, effectively improve the levelling of its subsequent sulfidation
Property, setting cutting part quickly cuts off extruded stock when facilitating extrusion.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the structural schematic diagram of cylindric material extrusion outlet.
Specific embodiment
As shown in the picture, a kind of extrusion molding apparatus for plastic material, including chassis 26, setting are two on chassis 26
Motor 31 and two speed reducers 32, the charging interface 27 that 26 top of chassis is set, be arranged on chassis 26 and with charging interface 27
The packing cylinder 28 of connection, the cylindric material extrusion being connected to packing cylinder 28 outlet 29 and cutting part;
One end of the packing cylinder 28 is equipped with the material extrusion twin-screw connecting with speed reducer 32, the other end and cylindric material extrusion and goes out
Mouth 29 is connected to, and material extrusion twin-screw includes the two screw rods 30 that setting and diameter gradually successively decrease diagonally downward, the upper end point of two screw rods 30
It is not protruded into the output axis connection of two speed reducers 32, lower end in cylindric material extrusion outlet 29, along it in cylindric material extrusion outlet 29
Diametrical direction is equipped with a vertical separating plate 33, and the length of vertical separating plate 33 is less than the length and cylinder of cylindric material extrusion outlet 29
Shape material extrusion outlet 29 is equipped with the space for accommodating 30 end of two screw rods close to one end of packing cylinder 28, makes two screw rods 30 and separates vertically
Plate 33 is not in contact;The cutting part setting exports on front side of 29 discharge ends in cylindric material extrusion, and the cutting part includes setting
An otic placode 35 and the cutting blade 34 hinged with otic placode 35 in 26 side of chassis.
The cutting blade 34 is arranged perpendicular to the extrusion direction of extruded stock.
It is located on front side of cutting part on the chassis 26 and is additionally provided with recessed portion, multiple groups rotatingcylindrical drum is provided in recessed portion
36, height locating for 36 top of rotatingcylindrical drum is identical as the height on 26 surface of chassis.
Working principle: the plastic material after mixing enters the material extrusion for entering back into charging interface 27 and being connected to charging interface 27
In cylinder 28, material extrusion twin-screw is driven to carry out squeezing for plastic material by two motors 31 and two speed reducers 32 connecting with two motors 31
Out, plastic material is extruded in the cylindric material extrusion outlet 29 being connected to packing cylinder 28 and is divided into mutually by vertical separating plate 33
The extrusion molding object for the two semicylinder shapes pasted, by rotating the cutting part after the suitable length of extrusion molding object
Cutting blade 34 cuts off extrusion molding object.
