Abstract
The utility model relates to a machine head device of a tube plastic extruding machine, comprising a machine head sleeve, a shunt, a die core, a die sleeve and a die sleeve press cover. The center of the mold core is provided with a fiber through-hole; a tube plastic flow channel is arranged between the die core and the die sleeve, the utility model is characterized in that bar injection screws are arranged between the die sleeve and the die sleeve press cover; the bar injection screws are provided with a stripe material hole; the stripe plastic hole is communicated with a tube plastic flow channel. The utility model has the advantages of performing stripe extrusions on the tube plastics of the various fibers, and stable stripe tube plastic extrusion, a smooth and round tube surface, and clear stripes.
Description
One, technical field
The utility model relates to a kind of beam tube extruder head device, especially relates to a kind of optical cable beam tube extruder head device.
Two, technical background
Central beam tube type optical cable in the market, it comprises oversheath and center beam tube, in the beam tube of center optical fiber is arranged, the center beam tube of this type of optical cable is the colourless PBT of one deck (polybutylene terephthalate (PBT)) layer; When in the fiber optic cable loose tube being special optical fiber or other special-use fiber, need carry out special identifier so that distinguish and identification to beam tube, extruding striped outside beam tube is exactly a kind of good identification method; Current optical cable is that skin at optical fiber coats a beam tube with the effect of beam tube extruder head device, and optical cable mainly is made up of head cover, current divider, core rod, die sleeve and die sleeve gland with beam tube extruder head device; But it can only carry out beam tube and extrudes, and can't be on the beam tube that extrudes extrudes carrying out striped.
Three, technology contents
At above-mentioned shortcoming, the purpose of this utility model is to improve a kind ofly can carry out optical cable that striped extrudes with beam tube extruder head device on the beam tube optical fiber bundle tubes.
A kind of optical cable beam tube extruder head device, comprise head cover, current divider, core rod, die sleeve and die sleeve gland, the center of core rod is a wire hole, and beam tube materials flow passage is arranged between core rod and the die sleeve, it is characterized by has the bar of notes screw on die sleeve and die sleeve gland, annotating on the bar screw has a striped material hole; Striped material hole communicates with beam tube materials flow passage.
The advantage that the utility model is compared with prior art had is, can carry out striped on the beam tube of different fiber and extrude having; Striped beam tube extrusion molding is steady, beam tube smooth surface, rounding, clear-cut texture.
Four, description of drawings
Figure 1 shows that structural representation of the present utility model.
Five, specific embodiment
As shown in Figure 1, a kind of optical cable beam tube extruder head device, comprise head cover 1, current divider 2, core rod 8, die sleeve 5 and die sleeve gland 4, the center of core rod 8 is a wire hole 6, beam tube materials flow passage 7 is arranged between core rod 8 and the die sleeve 5, it is characterized by has the bar of notes screw 3 on die sleeve 5 and die sleeve gland 4, annotating on the bar screw 3 has a striped material hole 9; Striped material hole 9 communicates with beam tube materials flow passage 7.
Optical cable is to pass in the wire hole 6 of optical fiber from core rod 8 with beam tube extruder head device operation principle; PBT enters beam tube materials flow passage 7 between core rod 8 and the die sleeve 5 by current divider 2, the striped material hole 9 of striped material notes bar screw 3 enters beam tube materials flow passage 7 simultaneously, and be combined into an integral body with the beam tube material and extrude and outside optical fiber, form the beam tube layer, on beam tube, form striped thus.
