Description
Technical field
The present invention relates to plastics-production apparatus field, specifically, the present invention relates to a kind of plastic extruder cooling body and extrusion
Device.
Background technology
Plastic extruder is the machine that plastic raw materials are cooled and shaped again through high extrusion pressure from extruder extrusion, and plastics are leaving machine
After head, cooling and shaping should be carried out immediately, otherwise can be deformed under gravity.The mode cooled down on present industrial is usual
Using water cooling, and it is different according to water temperature, it is divided into chilling and slow cooling, cold water direct circulation can cause plastics drastically to cool, also
It is chilling, is unfavorable for producing and processing, and preferable sealing is then needed using water cooling, can then goes out if there is poor sealing
The situation of existing leak, workshop can then impact if it find that leak to the environment in workshop, if at leak to electric wire, can
It can cause to leak electricity.In addition, water-cooled water consumption is larger, water resource waste is caused.The defects of to overcome water cooling, Ye You enterprises use
Air-cooled mode carries out cooling and shaping to plastics, but commonly air-cooled deposits the defects of cooling effect is bad.
The content of the invention
Based on this, the defects of the invention reside in prior art is overcome, there is provided a kind of plastic extruder cooling body, the plastics squeeze
Go out machine cooling body and cooling and shaping is carried out to plastics using the relatively low cold wind of temperature, and carry certain steam, water smoke in cold wind secretly, both
It can realize to plastics fast shaping, and can significantly reduces the internal stress of plastics, and cooling and shaping effect is good.
Another object of the present invention is to provide a kind of plastic extrusion apparatus.
