The purpose of this utility model realizes by following approach.
A kind of pre-cooler of plastic tube product line, its structural feature is: the pre-cooler of described plastic tube product line comprises the housing with interlayer, the inner chamber of housing is the material stream passed passage, the entrance point of described material stream passed passage is connected with the material outlet of machine head port mould, the port of export of material stream passed passage and the inlet of calibration sleeve are conducted, the closed at both ends of crustless sandwich, crustless sandwich and interlayer both ends of the surface constitute the cold passage of putting of pre-cooler, put cold passage and be provided with the import and the outlet of putting cryogen, described import is positioned at puts close head membrana oralis end on the cold passage, and described outlet is positioned at puts on the cold passage near the calibration sleeve end.
The pre-cooler of plastic tube product line of the present utility model, flow into by the import of putting cold passage when putting cryogen, and when flowing out by the outlet of putting cold passage, then can carry out preliminary cooling to the material embryo that enters pre-cooler material stream passed passage that flows out by the head membrana oralis, material embryo extexine toughness is strengthened, make the material embryo under the tractive force effect, be difficult for taking place disconnected pipe problem; Because the material embryo is subjected to the pre-cold-peace rubbing action of pre-cooler, head pressure is increased simultaneously, thereby help improving the plasticizing effect of raw material, improve the quality of products.Pass through the glossiness on the surface of control material stream passed passage simultaneously, also can improve the glossiness of material periblast greatly.
Describedly put the import and the outlet of cold passage or be arranged on the outer wall of crustless sandwich, or be arranged on the both ends of the surface of interlayer, or be arranged at simultaneously on the both ends of the surface of the outer wall of interlayer and interlayer.
Describedly put cryogen or for water, or be cold air.
The internal layer of described housing adopts the high metal material of thermal conductivity factor to make.
The cooling effect of the high more device of metal material thermal conductivity factor is good more, is beneficial to the material embryo more and is being subjected to good compression and rubbing action in the extrusion fast.
The metal material that described thermal conductivity factor is high is iron, stainless steel, copper.
The inner surface of the internal layer of described interlayer is through polishing or electroplating processes.
Internal layer inner surface after polishing or electroplating processes is very bright, the material embryo under the interaction of head pressure and tractive force, produce good pre-cold-peace friction with cover in the light after, the extexine of material embryo reflects the mirror surface luster the same with inner surface of inner race naturally.
Described housing with interlayer is a kind of housing of annular.
Described toroidal shell structure is: it comprises interior cover, overcoat, sealing plate, sealing ring, end between overcoat and the interior cover is for fixedlying connected, the other end between overcoat and the interior cover uses sealing ring and sealing plate with the interlayer end face seal, cavity between overcoat, interior cover and sealing ring and the sealing plate constitutes puts cold passage, be provided with import, outlet on the coat, the inner chamber of interior cover is the material stream passed passage.
Described fixedly connected or for being threaded, or be welding.
The cross section circle of described material stream passed passage.
Adopt dismountable the connection between the pre-cooler of described plastic tube product line and the head membrana oralis.
Adopt dismountable the connection with between the pre-cooler of plastic tube product line and the head membrana oralis, be convenient to both maintenance, change and installation.
Adopt dismountable being connected to be threaded between the pre-cooler of described plastic tube product line and the head membrana oralis.
In sum, the utility model has following advantage compared to existing technology:
The high temperature material embryo that is come out by the head membrana oralis is through the pre-cooler cooling of plastic tube product line, the material embryo of extruding like this is existing lowers the temperature and shrinks, material embryo external diameter and calibration sleeve internal diameter basically identical, can enter calibration sleeve easilier, reduced and calibration sleeve between heat transfer process, avoid problems such as calibration sleeve excessive heating and material embryo are obstructed to produce, thereby effectively improve the speed of production of plastic tube product line and produce stable.Simultaneously because after the inner surface of the internal layer of pre-cooler carried out polishing or electroplating processes, therefore can make the material embryo under the interaction of head pressure and tractive force, after the good pre-cold-peace friction of cover generation in the light, the extexine of material embryo reflects the mirror surface luster the same with inner surface of inner race naturally.
