Description
Technical field:
The present invention relates to a kind of radial extruding forming device of cut-fiber reinforcement rubber composite material, particularly a kind of cut-fiber reinforcement rubber continuous extrusion and in extrusion, realize the device of short fiber radial extruding forming in sizing material.
Background technology:
Short fiber-rubber composite is one of preparation high-performance tire desirable material.Discover, add short fiber in the sizing material, resistance to rolling, anti-slippery and the hysteresis loss of tire are obviously reduced, tyre surface tear resistance, anti-collapsing are used up the piece raising, can realize the lightweight of tire and the noise that travels is reduced.If short fiber is radial oriented in sizing material, more can improve the integral rigidity of tire, balance control, riding comfort and the tire wear of automobile all are improved.Short fiber radially is orientated, domestic and international many researchers have carried out extensive studies, the method that mainly solves and the device of employing have at present: the one, and the short fiber that elder generation's common head of employing is extruded is along the sizing material of circumferential orientation, be die-cut into the tyre surface section configuration, a piece is spliced to required tyre surface length again, this method efficient is very low, only is applicable to experimental study, also can't be applied in the actual production at present; The 2nd, the device of taking to change head and shape of the mouth as one speaks structure is directly extruded the radial oriented packing element of short fiber, vertically cut open again, cut along extruding the width of direction then by part requirement, though this method and apparatus has application extruding on the radial oriented sebific duct of short fiber, but this method and apparatus will be used on the tire production, but exists a lot of difficulties.Because tire tread is a product that definite shape and specification are arranged, if extrude packing element, must carry out secondary and cut open and cut splicing again, complex operation, production efficiency is low, also can influence tyre forming process.If direct extruded tread, its die size must be suitable with the overall diameter of tire, and the shape of the mouth as one speaks is huge, and the specification of extruder is huge, brings very big difficulty to machine-building, almost is difficult to realize, in addition, more can not realize the production of compound tyre surface.In sum, there is complex structure in existing apparatus, and production process is loaded down with trivial details, whole set equipment cost height, outstanding shortcoming such as the physics that the product quality of its production is difficult to reach desirable and chemical property.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that prior art equipment exists, seek to provide a kind of novel extrusion equipment device, in the cut-fiber reinforcement rubber composite material extrusion, this device can realize that short fiber is radial oriented in sizing material.
To achieve these goals, agent structure of the present invention comprises that head pressing plate, stereotype plate, resistance dam gripper shoe, runner plate, the glue valve that overflows, the glue adjusting bolt that overflows, flange, filter offset plate, resistance dam are regulated bolt, resistance dam regulating block, finalize the design regulating block and HTHP water pipe, its frame head apparatus main body is made up of flange, runner plate, resistance dam gripper shoe, stereotype plate and head pressing plate, the arrival end of head is designed to pyramidal structure, mid portion is a rectangular cross section structure, and the port of export forms dam shape structure by dwindling runner thickness; Flange and runner plate link, and runner plate and resistance dam gripper shoe link, and resistance dam gripper shoe and stereotype plate link, and stereotype plate and head pressing plate link; Be shaped on the screwed hole that eight diverse locations are symmetrically distributed on the front of flange, with eight double threaded screws flange and runner plate, resistance dam gripper shoe, stereotype plate, head pressing plate be linked together in order successively, the double threaded screw other end is fixed with nut; Be shaped on eight holes on the edge of flange, by the bolt connection flange is fixedlyed connected with extruder, the flange arrival end is placed the filter offset plate, be provided with an excessive glue valve directly over the flange front end and regulate bolt and link with excessive glue, excessive glue valve side is shaped on the glue hole of overflowing, the excessive glue step-down in excessive glue hole when head pressure is excessive, the switch in the glue hole of overflowing is controlled by the glue adjusting bolt that overflows; Flange inside is shaped on and adds the hot water channel, adds the hot water hole into and out of two and is positioned at flange front end right side; Place a pair of resistance dam regulating block in the middle of the resistance dam gripper shoe, resistance dam is regulated bolt one end and is fixed with the resistance dam regulating block, and the other end can be controlled the resistance dam gap thickness by being threaded and the resistance dam gripper shoe links by resistance dam adjusting bolt; Place a pair of typing regulating block in the middle of the stereotype plate and regulate the typing gap thickness, the typing regulating block is clipped between resistance dam gripper shoe and the head pressing plate, and the screw of placing by a pair of symmetry in head pressing plate front is fixed; Head pressing plate inside is shaped on and adds the hot water channel, adds the hot water hole into and out of two and is positioned at head pressing plate right side; The water inlet of the delivery port of head pressing plate and flange, flange and head pressing plate links by the HTHP water pipe, and circulating of hot water of realization heated head.
Apparatus of the present invention realize that the concrete steps of extruding and forming short fiber reinforced-rubber composite material in radial direction are that the rubber molten mass that will contain short fiber earlier joins in the extruder and extrudes processing by screw rod; Screw rod end in extruder barrel through extruding the axial orientation runner that rubber after the processing is squeezed into extruder head, utilizes short fiber with sizing material flow direction orientation, realizes short fiber axial direction orientation in the axial orientation runner of head; The resistance dam that will under the extrusion pressure effect, form through the sizing material behind the axial orientation then by thickness by contracted channel, utilize rubber to extrude the characteristics of expansion, roll in the process that short fiber in the sizing material expands rapidly after sizing material is by resistance dam, present the trend of inclination; Sizing material longshore current road after will expanding at last continues to flow, sizing material in the centre of runner and marginal portion owing to there is velocity gradient, make the aggravation of short fiber inclined degree, the radial oriented degree of short fiber increases, through via flow one segment distance and before being extruded by head, short fiber is realized radial oriented in sizing material.
Apparatus of the present invention compared with prior art have the following advantages: the one, can be applicable to have wide range of applications on the various general Rubber Extruders; The 2nd, can realize short fiber-rubber composite continuous extrusion, and make goods even, closely knit; The 3rd, the extrusion molding process middle short fiber that can realize short fiber-rubber composite radial oriented in sizing material; The 4th, the volume of device is little, simple in structure, runner is smooth and easy, easy operating, and lower for the technical level of operators requirement, product quality improves, and production cost of products is low.
