Description
Technical Field
The utility model relates to a production facility especially relates to extruder.
Background
The performance of the tire tread rubber reinforced by short fibers is an ideal material and technical means for preparing high-performance tires. Researches show that the short fiber is added into the rubber material, so that the rolling resistance, wet skid resistance and hysteresis loss of the tire can be obviously reduced, the tear resistance, chipping resistance and chipping resistance of the tire surface are improved, the light weight of the tire is realized, and the running noise is reduced; if the short fibers are oriented in the radial direction in the rubber compound, the overall rigidity of the tire can be improved, and the balance maneuverability, riding comfort and tire wear resistance of the automobile can be improved. How to make short fiber oriented along radial direction, many researchers at home and abroad have conducted extensive research, and the method and the adopted device mainly solved at present are as follows: firstly, short fibers extruded by a common machine head are punched into the shape of the section of a tire tread along the circumferential oriented rubber material, and then the rubber material is spliced to the required length of the tire tread by blocks, so that the method is low in efficiency, is only suitable for experimental research, and cannot be applied to actual production until now; secondly, a device for changing the structure of a machine head and a mouth shape is adopted to directly extrude a rubber tube with short fiber in radial orientation, then the rubber tube is longitudinally split, and then the rubber tube is cut according to the width required by a part along the extrusion direction, although the method and the device are applied to extruding short fiber radial orientation rubber tubes, the method and the device are used in tire production, but have a lot of difficulties because the tire tread is a product with a certain shape and specification, if the rubber tube is extruded, secondary splitting and re-cutting splicing must be carried out, the operation is complicated, the production efficiency is low, and the tire forming process is influenced; if the tread is directly extruded, the size of the mouth shape of the tread is equal to the outer diameter of the tire, the mouth shape is huge, the specification of an extruder is huge, great difficulty is brought to mechanical manufacture, and the tread is almost difficult to realize; in addition, the production of composite treads is less likely to be achieved.
