Description
Technical field
The present invention relates to rubber manufacturing machinery technical field, in particular to a kind of bidirectional feed Rubber Extruder.
Background technology
Bidirectional feed Rubber Extruder, also known as extruder, is one of process equipment important in rubber production.In the machine-shaping of rubber industry sizing material, bidirectional feed Rubber Extruder is listed as two leading greatly production machines together with calender, of many uses, can the various shaped rubber material such as the various strip of processing and manufacturing, tubulose, bar-shaped, tabular, and along with the development of science and technology, the bidirectional feed Rubber Extruder of cash production tabular sizing material, steel cord adhesive plaster and metal, fiber wire rod can cover glue etc.
Often there is rubber and other auxiliary material mixed proportions difference comparatively greatly in tradition bidirectional feed Rubber Extruder, thus affects the elastomeric material quality extruded when charging.
Conventional extruder head forms looping pit by core rod and die sleeve to realize producing sebific duct, but when needing the sebific duct producing different-thickness, all need just open handpiece, change core rod and die sleeve, need the axiality regulating core rod and die sleeve simultaneously, ensure the sebific duct uniform wall thickness produced, but each regulation time at least needs 30 minutes, operate unskilled personnel even 1 to 2 hours, and during this, sizing material one continuously outflows straight through machine mouth, causes a large amount of raw material and artificial waste like this, and use work efficiency is low and quality stability is poor.
Summary of the invention
The object of the present invention is to provide a kind of bidirectional feed Rubber Extruder, to solve the deficiencies in the prior art.
For realizing the object of the invention, the technical scheme of employing is:
A kind of bidirectional feed Rubber Extruder, comprise feeding cylinder, bearing, housing, motor and rotating shaft, rotating shaft is connected by bearing fit with feeding cylinder, motor is fixedly connected with rotating shaft, it is characterized in that, described feeding cylinder two ends are respectively equipped with charging aperture and glue-feeder, are provided with discharging opening in the middle part of it; Described rotating shaft two ends are provided with two ends screw thread, and two ends thread rotary orientation is contrary; Described housing is connected by discharging opening with feeding cylinder, and shell one end is fixedly connected with die sleeve, and die sleeve center is provided with through hole; Be provided with the annular canister be fixedly connected with its inwall in described housing, be connected with core rod by threaded engagement in annular canister, core rod runs through housing, and housing is stretched out in core rod one end, and the other end aligns with die sleeve through the through hole of die sleeve; Described die sleeve inner surface and core rod outer surface form discharge opening; The periphery of described core rod is provided with screw thread, and the periphery of core rod is provided with the core rod cover connected by threaded engagement.Further, described internal diameter of the seal ring is provided with cannelure, and cannelure end face has good anti-wear performance, can improve the service life of sealing ring.
Further, described core rod is provided with cavity, makes compound be unlikely to overheated carbonization.
Further, described core rod outer surface is provided with projection, makes batch mixing even, improves rubber tube quality of materials.
The invention has the beneficial effects as follows, enter auxiliary material by charging aperture, glue-feeder enters rubber, then by reverse thread, auxiliary material and rubber is moved to centre, Homogeneous phase mixing, thus improves the elastomeric material quality produced.When the rubber tube wall thickness needing to produce or rubber tube internal diameter need to change, by rotating core rod, core rod is made to stretch out die sleeve through hole, core rod cover is being changed by threaded engagement, realize rubber tube internal diameter and the change of rubber tube wall thickness, avoid needing dismounting head to change core rod and die sleeve, need to regulate axiality, the waste working time simultaneously.
