Abstract
The utility model provides a special extruder for thermoplastic elastomers, which comprises an electrical motor, a speed reducer, a machine seat, a propulsion screw rod, a sleeve barrel and an extruding head. The utility model is characterized in that an oil sleeve and a heater are arranged on the surface of the sleeve barrel, the height of screw threads of the propulsion screw rod is gradually changed from high to low, and a mixing section with mixing teeth is arranged in the middle section of a main body of the propulsion screw rod; spiral equal plastication sections are arranged at the tag end of the propulsion screw rod. The stock temperature of the utility model can be 100 DEG C to 200 DEG C, the heat exposure is uniform and the phenomena of overheating in local positions and scorching part materials can not happen. The arrangement of the screw pitch and the screw thread height of the propulsion screw rod, the arrangement of the plastication sections and the arrangement of the mixing section are reasonable, and the differences of the natural longitudinal pulling force and the natural lateral pulling force of a film can be eliminated, thus ensuring that the plastication of materials is completely and fully and the mixing is uniform. Therefore, the utility model can meet the requirement of the mechanical properties of producing electric wires, cables, rubber pipes, sealing adhesive strips by thermoplastic elastomers.
Description
Technical field
The utility model relates to the special-purpose extruder of a kind of thermoplastic elastomer (TPE), belongs to plastics or rubber extrusion equipment technical field.
Background technology
At present, extruder totally divides two big class, i.e. plastic extruder and Rubber Extruders.The common plastics extruder is better relatively because of the flowability of plastics, the draw ratio of its augering screw is relatively large, and Rubber Extruder is mobile poor because of it, general draw ratio is less, screw rod is shorter, because thermoplastic elastomer (TPE) and rubber or plastics performance is all inequality, uses existing plastics or Rubber Extruder as extrusion equipment, the equal imperfection of application performance.Market in urgent need has the extrusion equipment of proper property.
Summary of the invention
The utility model provides a kind of extruder of thermoplastic elastomer (TPE) special use, and main purpose is by the reasonable setting to extruder draw ratio, compression ratio, mixing section, the section of plasticating and attemperating unit, to adapt to various thermoplastic elastomer (TPE) extrusion moldings.
The technical solution of the utility model is achieved in that the special-purpose extruder of this thermoplastic elastomer (TPE), basic structure comprises: motor, reductor, support, augering screw, sleeve, extruder head is characterized in that: the sleeve appearance is provided with oil jacket and heater, and the thread depth of augering screw is by the extremely low gradual change of sound, augering screw main body stage casing is provided with the mixing section of mixing tooth, and the augering screw end is provided with the section of plasticating of spiral equalization.
The special-purpose extruder of described thermoplastic elastomer (TPE), the gradual change scope of the thread depth of described augering screw is 8.75-3.5.
The augering screw draw ratio of the special-purpose extruder of described thermoplastic elastomer (TPE) is 12-15: 1.
The special-purpose extruder of described thermoplastic elastomer (TPE), the pitch of described augering screw and the ratio of diameter are 0.8-0.9: 1.
The special-purpose extruder of described thermoplastic elastomer (TPE), the described augering screw segment length of plasticating is set to pitch * 4.
The special-purpose extruder of described thermoplastic elastomer (TPE), the mixing tooth segment length of described cardan shaft is set to pitch * 2.
The special-purpose extruder of described thermoplastic elastomer (TPE) is provided with plate washer oil jacket is divided into two sections or multistage on the described oil jacket, thermometer, oil-in and oil-out are set on every section oil jacket.
Extrusion shaping machine provided by the utility model, for telescopic, single screw rod, conduction oil circulation are conducted heat and constant temperature, electric heater heating conduction oil, temperature of charge can choose at random between 100-200 ℃, and be heated evenly, can not produce hot-spot, partial material is burnt phenomenon; The reasonable setting of the pitch of augering screw and thread depth, the section of plasticating, mixing section, be enough to eliminate vertical, the lateral pull difference of film nature, guarantee that material plasticates cmpletely, mixing even, can satisfy the mechanical performance requirement of producing electric wire, cable, sebific duct, sealing joint strip with thermoplastic elastomer (TPE).
