Description
Technical field
The present invention relates to a kind of band extrusion molding machines, and in particular to a kind of screw rod banded extruder with pre-pressing function.
Background technology
Screw rod banded extruder is common extrusion shaping machine, and in the prior art, screw rod banded extruder includes driving device, extrusion material
The components such as cylinder, feeding device, extrusion screw rod and mouth mold.Material is after feed inlet is sent into extrusion cylinder, through extrusion screw rod by material
It pushes forward, as material is pushed ahead, the rotation of extrusion screw rod generates very strong compressing force and shearing force, and compressing force to material
Much larger than shearing force.The compressed mouth mold that is advanced to of material squeezes out into strips through porous plate, then cuts off molding.
Material is entered by charge door during banded extruder is extruded, if there is bulk gas in material, may be occurred
Gas explosion phenomenon can seriously affect the quality of extruded moulding sample.Therefore, in the actual production process, need first to carry out material
The idiosome with certain volume, some strength is made in pre-molding, and the gas in material is fully discharged, then again adds idiosome
Enter and carries out extruded moulding in banded extruder.But generally manual operation is needed, is made in the general production process of horizontal screw banded extruder
Precompressed and extrusion are carried out to material with two equipment, labor intensity is big, low production efficiency.
Invention content
When the technical problem to be solved by the present invention is to contain bulk gas in material, it can occur in banded extruder extrusion process
Gas explosion phenomenon influences the final Forming Quality of material, and it is an object of the present invention to provide a kind of screw rod banded extruder with pre-pressing function, can incite somebody to action
Material carries out precompressed, fully drives the gas in material away, and realize precompressed and extruded moulding automatic integratedization.
The present invention is achieved through the following technical solutions：
A kind of screw rod banded extruder with pre-pressing function, including holder, the holder are equipped with driving box and extrusion cylinder, institute
State driving box and extrusion cylinder to be tightly connected, be equipped with motor, retarder, transmission shaft and shaft coupling in driving box, the main shaft of motor with
The input terminal of retarder is connected, and the output end of retarder is equipped with transmission shaft, and transmission shaft is connected by shaft coupling with extrusion screw rod,
Extrusion screw rod is accommodated in the extrusion cylinder, extrusion cylinder is equipped with extrusion charge door and extrusion discharge port, further includes pre- pressure cylinder, described
Pre- pressure cylinder is horizontal and is set to the top outside driving box, and being horizontally disposed in pre- pressure cylinder has precompression screw, is additionally provided on pre- pressure cylinder
Precompressed charge door and precompressed discharge port, the precompressed discharge port are located at precompression screw axial positions, further include being respectively arranged at
The intermeshing transmission gear of a pair in precompression screw and transmission shaft, the transmission gear are located in driving box.
The present invention is further improved on the architecture basics of existing horizontal screw banded extruder, is equipped in driving upper box part
Precompressed mechanism with pre-pressing function, precompressed mechanism include pre- pressure cylinder, are equipped with precompression screw in pre- pressure cylinder, precompression screw passes through rotation
Turn to generate compressing force to material in pre- pressure cylinder, make material compression, fully excludes the gas in material, it is effigurate to form tool
Idiosome.It in addition, handling by precompressed, can not only exclude to influence its molding gas in material, idiosome can also be made to have one
Determine intensity, idiosome can get higher intensity through banded extruder extruded moulding again.It is respectively set in precompression screw and extrusion screw rod mutually
The transmission gear of engagement drives extrusion screw rod by motor, and precompression screw rotation, realization pair are driven through transmission gear transmission driving force
Material precompressed automatic progress synchronous with extrusion, saves the operating time, has saved human cost, and simplify mechanical structure, just
In installation and maintenance management.The rotation speed of precompression screw and extrusion screw rod can be adjusted by the way that the transmission gear of different size is arranged
Degree.
Extrusion screw rod at the corresponding position of extrusion charge door is equipped with discontinuous screw thread, and feeds in extrusion
Flight pitch on the extrusion screw rod of mouth section is less than the flight pitch on other positions of extrusion screw rod.
The extrusion screw rod of extrusion charge door section primarily serves the effect of conveying material in the prior art, by increasing on it
Equipped with discontinuous screw thread, and the flight pitch of this section is small compared with the flight pitch at other positions, mainly increases the shearing of screw rod
Power carries out simple " granulation " processing to the material with certain idiosome, the material through precompressed is made to can smoothly enter into squeezing for extrusion cylinder
Press section.
The precompressed discharge port is located at the top of extrusion charge door, so that the precompressed sample squeezed out from precompressed discharge port is fallen into crowded
In charge door.
Precompressed mechanism, which is arranged, to be made to squeeze out precompressed discharge port above extrusion charge door it is ensured that precompressed discharge port is located at
Precompressed sample is fallen directly into extrusion charge door, or only so that material is automatically added to extrusion charging through the connection of simple connecting plate
In mouthful.Help to realize precompressed and extrusion automation mechanized operation.
Compared with prior art, the present invention having the following advantages and advantages：
1, the present invention is a kind of screw rod banded extruder with pre-pressing function, can material first be carried out precompressed, fully drive object away
Gas in material, it is ensured that material will not occur " gas explosion " and influence final molding quality；
2, the present invention is a kind of screw rod banded extruder with pre-pressing function, is handled by precompressed, and idiosome can be made to have one
Determine intensity, idiosome can get higher intensity through banded extruder extruded moulding again.；
3, the present invention is a kind of screw rod banded extruder with pre-pressing function, simple in structure, realizes precompressed and extrusion simultaneously
It is automatic to carry out, the operating time is saved, human cost has been saved, is improved work efficiency.
