Description
Technical field
The utility model relates to a kind of Novel machine head of extruding machine attemperator, belongs to insulation cooling technology field.
Background technology
Rubber, plastics mix extruder continuously, the device of extrusion molding by the major parts such as charging system, extrusion system, transmission mechanism, heating and cooling system and control system being used for of forming.
Extrusion system comprises screw rod, machine barrel, hopper, head and mould, and plastics plastify into uniform melt by extrusion system, and in this course under institute's build-up pressure, by the continuous extruder head of screw rod.
Head and mould: head is made of steel alloy inner sleeve and carbon steel overcoat, mould is housed in the head, the effect of head is that the plastic melt that will rotatablely move changes the parallel lines motion into, uniform and stable ground imports in the die sleeve, and give the briquetting pressure of plastics with necessity, plastics plastify compacting in machine barrel, flow into head mould along certain runner by the head neck through the porous filter plate, the core rod die sleeve suitably cooperates, the ever-reduced annular space of Formation cross-section makes plastic melt form continuously closely knit tubulose clad around heart yearn.
Attemperator is not installed on the existing cross-head, produce because of the reduction of temperature in the time of can causing like this melt to flow out and solidify, in case there are some to be set on the tube wall, will cause tube wall is stopped up, so just can not guarantee the normal effectively outflow of melt, so this is a problem that urgent need will solve.
Summary of the invention
Temperature reduces solidifying of producing in order to solve that existing cross-head is not installed attemperator and when causing melt to flow out, thereby causes the obstruction of tube wall, and having affected the normal of melt effectively flows out; The utility model proposes a kind of Novel machine head of extruding machine attemperator.
The technical scheme that the utility model adopts is:
The Novel machine head of extruding machine attemperator, comprise the melt outlet, the hot water inlet pipe, outer tube, the hot water outlet pipe, head plate, inner tube, axle sleeve, melt flows hole and sleeve pipe, outer tube sleeve is in the inner tube outside, outer tube and inner tube two ends are sealed by head plate, hole is offered at the head plate center, axle sleeve inserts head plate by hole, head plate is provided with the melt flows hole, the melt flows hole is opened between axle sleeve and the inner tube, outer tube is provided with sleeve pipe and hot water outlet pipe, and sleeve pipe is provided with the hot water inlet pipe, and inner tube is provided with the melt outlet, casing pipe sleeve is in the melt outlet outside, and the melt outlet has reached the device outside by sleeve pipe.
Seal with steel plate between sleeve pipe and the melt outlet; Outer tube diameter has formed the hot water flow passage greater than diameter of inner pipe between outer tube and the inner tube.
Advantage of the present utility model: this device is installed on the cross-head, hot water enters the hot water flow passage from the hot water inlet pipe, and be full of whole passage, and then flow out from the hot water outlet pipe, form like this a circulatory system, guaranteed the temperature of melt, played heat insulation effect, this outer shaft can disassemble, if melt solidifying is on tube wall like this, just can lift down cleaning, guarantee the normal effectively outflow of melt.

Fig. 3 is the rearview of Novel machine head of extruding machine attemperator;
Fig. 4 is the top view of Novel machine head of extruding machine attemperator;
Among the figure: 1, melt outlet 2, hot water inlet pipe 3, outer tube 4, hot water outlet pipe 5, head plate 6, inner tube 7, axle sleeve 8, melt flows hole 9, sleeve pipe.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, the Novel machine head of extruding machine attemperator, comprise melt outlet 1, the hot water inlet pipe 2, outer tube 3, the hot water outlet pipe 4, head plate 5, inner tube 6, axle sleeve 7, melt flows hole 8 and sleeve pipe 9, outer tube 3 is enclosed within inner tube 6 outsides, outer tube 3 and inner tube 6 two ends are by head plate 5 sealings, hole is offered at head plate 5 centers, axle sleeve 7 inserts head plate 5 by hole, head plate 5 is provided with melt flows hole 8, melt flows hole 8 is opened between axle sleeve 7 and the inner tube 6, outer tube 3 is provided with sleeve pipe 9 and hot water outlet pipe 4, sleeve pipe 9 is provided with hot water inlet pipe 2, inner tube 6 is provided with melt outlet 1, and sleeve pipe 9 is enclosed within melt outlet 1 outside, and melt outlet 1 has reached the device outside by sleeve pipe 9.
Seal with steel plate between sleeve pipe 9 and the melt outlet 1; Outer tube 3 diameters have formed the hot water flow passage greater than inner tube 6 diameters between outer tube 3 and the inner tube 6.
The effect of melt outlet 1 is the passage that melt flows out from device; Hot water inlet pipe 2 and hot water outlet pipe's 4 effect is to have guaranteed that hot water can form one and pass in and out the freely circulatory system; Axle sleeve 7 is demountable, so just can lift down cleaning, prevents that tube wall from stopping up; Melt flows hole 8 is that melt enters inner passage; The effect of sleeve pipe 9 has guaranteed also melt to be played certain heat insulation effect at melt outlet 1.
Operation principle: the operation principle of this device is very simple, hot water has entered the hot water flow passage that is formed by outer tube 3 and inner tube 6 from hot water inlet pipe 2, by hot water outlet pipe 4 hot water is sent again, so just formed a hot water cyclesystem, melt is extruded from the screw rod of extruder and is flow to cross-head, because device is installed on the cross-head, the circulation meeting of hot water is played an insulation effect to melt, this effect can guarantee the temperature that melt flows out, thereby can not be set on the tube wall because melt temperature reduces, caused obstruction, can dismantle because of axle sleeve 7 again, so can often lift down cleaning, can guarantee so the normal effectively outflow of melt, improve the output of product.
