Rubber pipe extruder, also known as extruder, is one of process equipment important in rubber production.In the machine-shaping of rubber industry sizing material, rubber pipe 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 rubber pipe extruder of cash production tabular sizing material, steel cord adhesive plaster and metal, fiber wire rod can cover glue etc.
The rotating shaft of conventional rubber pipe extruder is in long-term rotation, after making ring wear, sizing material can enter in the bearing of rotating shaft, damage bearing, rotating shaft is broken down, cause rotating shaft not run well, thus affect the production efficiency of rubber pipe extruder and the quality of product, too increase maintenance cost and production cost.
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 rubber pipe 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 rubber pipe extruder, comprise feeding cylinder, bearing, housing and rotating shaft, rotating shaft is connected by bearing fit with feeding cylinder, it is characterized in that, described feeding cylinder one end is provided with glue-feeder, and the other end is provided with discharging opening; Described rotating shaft is provided with feeding screw thread; The inwall of described feeding cylinder is equipped with the first dividing plate and second partition, and the first dividing plate and second partition are between bearing and feeding screw thread; Be provided with circular column between described first dividing plate and second partition, and circular column inwall is set to the conical surface; Be provided with sealing ring by cone match with it in described circular column, between sealing ring and the first dividing plate, be provided with spring; 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, by circular column and sealing ring cone match, make sealing ring be close to rotating shaft under the force of a spring, even if after ring wear, also can realize auto-compensation, have good sealing effectiveness.Thus avoid sizing material can enter in the bearing of rotating shaft, damage bearing etc.
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.
