The inner core and outer sheath of the rainbow tube can be completed together on a set of equipment only by changing the inner core positioning dies and dies with different calibers as the detachable inner core positioning dies and dies are adopted, furthermore, plastics are not easy to stack in the die head, thus being characterized by quick discharge and high production efficiency.

Description

The manufacturing equipment of rainbow tube

Technical field

The present invention relates to a kind of making apparatus of rainbow tube, in particular a kind of making apparatus of neon light tube.

Background technology

Usually, neon light be manufactured with following several steps: earlier with plastics by the extruder extrusion die, in die head, wear with copper wire simultaneously, at this moment, what extrude from die head is exactly the inner core of a band copper wire, again inner core is severed, the LED fluorescent tube is connected on the copper wire, and then inner core passed die head, and and form a plastic tube that diameter is thicker with the plastics that die head is extruded, become lines through the annular knurl of edge knurling machine, make that light that the LED fluorescent tube sends can scattering, through supercooling, just become neon light at last, this neon light claims rainbow tube again.And the machinery of making this rainbow tube also is to be made of discharge mechanism, extrusion mechanism, annular knurl mechanism, cooling body and haulage gear basically.Extruder structure of the prior art is a lot, and the extruder that the making rainbow tube is used, its screw rod all is to adopt BM type screw rod usually, the structure of this screw rod sees that the patent No. is the United States Patent (USP) of US3353327, perhaps the patent No. is 87210566, and name is called the Chinese utility model patent of " screw rod of extruder ", and these two kinds of screw rods can adopt, this screw rod is when the extruding rainbow tube, and melting effect is better.Its structure of die head that is installed on this screw cylinder then is comparatively simple, this die head also comprises core rod, inner core positioning module, mould tube and mouthful mould, wherein inner core positioning module and core rod are integral structure, and mouthful mould and mould tube also are integral structure, and also being provided with two split channels on the core rod, these two split channels are on same plane.The die head of this structure, because the integrative-structure of its inner core positioning module and core rod, and the integrative-structure of mouthful mould and mould tube, just obtain restriction when making the rainbow tube of making different-diameter, change die head and bother very much; And two split channels are on same plane on the core rod, and the junction of two split channels just becomes a straight way, make the plastics of extruding form a dead angle in the junction of two passages, result in blockage at this place easily, influence the quality that rainbow tube is extruded.Make the annular knurl mechanism of this rainbow tube, its structure is also fairly simple, basically also be to constitute with bolster and hobboing cutter, this bolster and hobboing cutter fixedly install, unadjustable, thereby the rainbow tube of extruding causes the lines depth injustice during annular knurl under the traction of haulage gear, lines is unintelligible, the dispersion effect when having influenced the LED lamp luminescence.What cooling body simultaneously of the prior art adopted is single sink structure, and its cooling is not thorough, has influenced the making effect of rainbow tube yet.

Summary of the invention

In view of the deficiency that background technology exists, the technical problem to be solved in the present invention provides a kind of plastics when extruding in die head smooth flowing is difficult for piling up, and the manufacturing equipment of the rainbow tube that can change at any time inner core positioning module and mouthful mould.

For this reason, the present invention takes following technical scheme to realize: a kind of manufacturing equipment of rainbow tube, comprise discharge mechanism, extrusion mechanism, annular knurl mechanism, cutting mechanism, two cooling bodies and haulage gear, described cutting mechanism is installed on the haulage gear, wherein, described discharge mechanism, extrusion mechanism, annular knurl mechanism, cooling body and haulage gear are put successively, described extrusion mechanism is by barrel, screw rod and die head constitute, it is characterized in that described die head comprises the aligning axle, core rod, the mould tube, inner core positioning module and mouthful mould, described core rod is enclosed within on the aligning axle, described core rod is inserted in the described mould tube, described inner core positioning module releasably is installed on the described core rod, described mouthful of mould also releasably is installed on the described mould tube, described mould tube is connected by the barrel of discharging opening and described extruder, described core rod is provided with two split channels, this two split channels shape in an angle, the arrival end of described two split channels is by the through hole on the mould tube, discharging opening and described barrel are connected, and the passage of the port of export of described two split channels and described mouthful of mould is connected; Described annular knurl mechanism comprises body, bolster and hobboing cutter, and described bolster is connected with first screw rod, and described body is provided with first screw, described first screw rod and described first screw coupling; The roller bearing of described hobboing cutter is connected with second screw rod, and described body is provided with second screw, described second screw and described second screw rod coupling; Described cooling body comprises first tank, second tank, and the both ends of described first tank and described first tank of the second tank upper and lower settings and second tank are provided with roller; Described screw rod is made up of feeding section, melt zone and homogenize section, and wherein the melt zone of screw rod is made of main thread and deputy thread, the equidistant gradual change of described deputy thread, and inconsistent with the diameter of main thread, and described deputy thread pitch equates that screw channel is from depth to shallow; The afterbody of described aligning axle is provided with screw thread, is provided with the nut that mates with described screw thread on this afterbody, and after described core rod was enclosed within on the aligning axle, an end face of described nut contacted with described core rod.

This die head of the present invention, since its two split channel on core rod in an angle, i.e. each split channel oblique setting on core rod, thereby, after screw rod is extruded plastics, just dirty when entering core rod behind the process discharging opening along the inclined-plane of split channel, can not pile up, form the dead angle, therefore, from having solved the passage in the die head to a great extent owing to stopping up the problem that reduces production efficiency, make smoothness when rainbow tube is extruded, improved the making quality of rainbow tube; And the bolster of annular knurl mechanism and cutter shaft are with after first screw rod, second screw rod are connected, form an adjustable mechanism, make behind the rainbow tube annular knurl lines depth unanimity, lines is clear, so the astigmatic performance when making rainbow tube behind the annular knurl luminous is greatly improved; The setting of its two-layer tank makes and the rainbow tube the extrude cooling that can circulate to have improved cooling effect; This structure of screw rod in its extrusion mechanism, melting effect is good, has reduced energy consumption, reduces pressure, has improved the rotating speed of screw rod, and has improved output simultaneously; The setting of aligning axle tailing screw flight, nut by adjusting nut, just can make core rod move in the mould tube, with the extrusion capacity of plastics in the control die head.
