Description
Technical field
The utility model relates to a kind of Polymer Processing device, especially a kind of continuous roving glass fiber extrusion device.
Background technology
Glass added extrude jointly in the polymer and can play humidification to polymer, particularly roving glass fiber continuously can have extraordinary reinforced effects to the polymer of extruding.But; Owing to continuous roving glass fiber in extrusion advances in runner is a quite irregular activity, therefore occurs the situation of phase mutual interference continuously between the roving glass fiber easily, and this is easy to cause glass to extrude difficulty; Make glass skewness in product, the quality that influence is extruded.Though being arranged now, a kind of mode that adopts independent runner improves the processing of continuous roving glass fiber; But the mode that should in independent runner, send into glass is complicated; And the forward travel state of glass in runner also caused it to rupture easily, and be difficult to stable extruding for a long time.
Summary of the invention
The purpose of the utility model is: a kind of continuous roving glass fiber extrusion device is provided, and it can not only avoid phase mutual interference between the continuous roving glass fiber, and glass easy fracture not in the extrusion, can guarantee the stability extruded, to overcome the deficiency of prior art.
The utility model is achieved in that continuous roving glass fiber extrusion device, comprises pedestal, on pedestal, is connected with hot flow path, in the sidewall of pedestal and hot flow path, is equipped with water back; On the sidewall of hot flow path, be provided with the glass charging aperture, be connected with more than one independent runner at the front end of hot flow path; Independent runner comprises columniform from heating shell body, is provided with square die cavity in the shell body heating certainly, in square die cavity, is provided with staggered up and down spacing block, and the end that heats shell body certainly connects hot flow path, is connected with outlet at the front end that heats shell body certainly.
The cast gate of hot flow path is fan gate or branch shape cast gate.Because the hot flow path temperature is higher, residence time of material length can cause aging, the degraded of material, therefore, adopts such structure can reduce the time of staying of material in hot flow path.
On the sidewall of square die cavity, be provided with the through hole corresponding with the spacing block position, spacing block inserts in the square die cavity from through hole.After square die cavity passes with continuous roving glass fiber in the convenient elder generation of such structure, again spacing block is inserted, make continuous roving glass fiber form sinusoidal wave form.
The formation of spacing block comprises fixed block, cylinder and needle roller; Inboard at fixed block is provided with chute, and needle roller passes cylinder, and the two ends of needle roller snap in the chute, on the inwall of chute, is provided with regulating tank.This spline structure can be regulated the height of spacing block, forms sinusoidal wave crest height to change continuous roving glass fiber.
In outlet, be provided with Vltrasonic device.In outlet the quality that Vltrasonic device can improve extruded product is set, Vltrasonic device then can adopt equipment such as ultrasonic generator commonly used in the prior art.
In hot flow path, be provided with the melt control valve.The melt control valve is used for regulating the melt flow of hot flow path, avoids causing continuous roving glass fiber when getting into hot flow path, to rupture because of melt flow is excessive.
Owing to adopted technique scheme; Compared with prior art; The utility model is employed in the mode that spacing block is set in the independent runner, utilizes spacing block that continuous roving glass fiber is advanced with sinusoidal wave form in independent runner, and independent runner has not only been avoided phase mutual interference between the continuous roving glass fiber; And advancing of sinusoidal wave form can effectively avoid the fracture of continuous roving glass fiber, improved production efficiency; The utility model is employed in the structure that square die cavity is set in the independent runner, after can square die cavity being taken out so continuous roving glass fiber is put on, and puts into independent runner again, makes the operation of putting into continuous roving glass fiber obtain simplifying, and is easy to use.The utility model is simple in structure, and is easy to make, with low cost, and result of use is good.
