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.
Utility model content
The purpose of this utility model is to provide a kind of rubber pipe extruder, to solve the deficiencies in the prior art.
For realizing the utility model object, 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 beneficial effects of the utility model are, 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.
