Abstract
The utility model discloses a novel plastic tube sizing and cooling device, which comprises an outer sizing sleeve, wherein an inner cooling sleeve is installed in an inner cavity of a plastic tube inside the outer sizing sleeve, and a ring-shaped channel for the plastic tube to pass through is arranged between the outer sizing sleeve and the inner cooling sleeve. The inner cooling sleeve is arranged inside the plastic tube, so as to realize the dual cooling of the inner and the outer surfaces of the plastic tube, thereby accelerating the cooling; at the same time, the inner cooling sleeve can perfectly control the thickness of the plastic tube, so that the thickness deviation of the plastic tube is greatly reduced and the production speed is improved by above 50 percent; and the requirement on the sag resistances of plastic tube materials is greatly reduced.
Description
Technical field
The present invention relates to a kind of plastic pipe manufacturing equipment, relate in particular to a kind of cooling apparatus for shaping of plastic pipe.
Background technology
As shown in Figure 2, produce the cooling apparatus for shaping of the smooth plastic pipe of inside and outside wall surface at present, how cool off the mode of production of sizing by being located at 1 pair of tubing of outer calibration sleeve in the Vacuum shaping groove.Adopt this mode of production, the operation principle of tube forming cooling is the outer surface cooling and shaping that at first makes tubing, inside gradually again cooling and shaping, and finally pipe material inner wall is cooled off, until the complete cooling and shaping of whole tube wall of tubing.When adopting this kind mode to produce the heavy caliber thick wall plastic pipe, because the poor thermal conductivity of plastics, required cool time of finalizing the design is longer, cooling and shaping to plastic pipe is often insufficient, can cause occurring the molten phenomenon of hanging down, promptly, under the gravity effect, continue to flow, thereby form the plastic tube that wall thickness does not wait to the horizontal minimum point place of tubing because the plastics of molten state are still arranged before plastic pipe is finalized the design fully.The tube wall thickness inequality has a strong impact on the overall performance of tubing.Because the cooling and shaping efficient of this kind type of cooling is low, also restricted the lifting of plastic pipe speed of production simultaneously.
Summary of the invention
Technical problem to be solved by this invention provide a kind of tube wall thickness evenly, cooling and shaping efficient high the novel plastics pipe cooling apparatus for shaping.
For solving the problems of the technologies described above, technical scheme of the present invention is: the novel plastics pipe cooling apparatus for shaping, comprise outer calibration sleeve, the plastic tube inner chamber of described outer calibration sleeve inside is equipped with interior coolant jacket, the circular passage of passing through for plastic pipe between described outer calibration sleeve and the described interior coolant jacket.
Owing to adopted technique scheme, the present invention is arranged on the interior coolant jacket of plastic pipe inside by employing, has realized the inside and outside surperficial dual-cooled of tubing, thereby has accelerated cooling velocity; Simultaneously, coolant jacket plays a good role to the control of tube wall thickness in this, makes the tube wall thickness deviation reduce significantly, and speed of production promotes more than 50%; Also greatly reduce tubing raw material sag resistant performance demands.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the prior art constructions schematic diagram.
The specific embodiment
As shown in Figure 1, the novel plastics pipe cooling apparatus for shaping comprises outer calibration sleeve 1, and the plastic tube inner chamber of described outer calibration sleeve 1 inside is equipped with interior coolant jacket 2, the circular passage of passing through for plastic pipe between described outer calibration sleeve 1 and the described interior coolant jacket 2.
More particularly, present embodiment is made up of extruder head 3, the interior coolant jacket 2 that is provided with helical form cooling duct 21, cooling line 6, outer calibration sleeve 1, vacuum sizing case 4 etc.Interior coolant jacket 2 is fixed on the core 5 by screw.Interior coolant jacket 5 outer walls contact with the inwall of tubing, cooling water enters helical form cooling duct 21 by cooling line, the cooling water of continuous-flow and interior coolant jacket 2 outer walls carry out heat exchange, and the cooling medium after the heat absorption is discharged, and the cooling medium of low temperature continuously injects; The continuous cooling of 2 pairs of tubing of coolant jacket in finishing, the supporting role of simultaneously interior coolant jacket 2 make tubing can not produce circumferential wall unevenness because of molten hanging down.
The above specific embodiment only is to give an example to of the present invention; protection scope of the present invention is as the criterion with the content of claim; as the common engineers and technicians in present technique field, any equivalence techniques conversion of making based on the present invention is also within protection scope of the present invention.
Claims (2)
