Embodiment
To make the purpose of this utility model, technical scheme and advantage clearer, clear and definite, develop simultaneously implementation referring to the drawings
The utility model is further described example.
The machine barrel cooling system of extruding machine 1 as shown in Figure 1 and Figure 2, including be sheathed on the outside of machine barrel between machine barrel outer wall
Form cooling water and flow through the coolant jacket 2 in space, be arranged on coolant jacket 2 and connect the and of water inlet pipe 3 that cooling water flows through space
Exit branch 4 and the water inlet manifold 5 and outfall sewer 6 connected respectively with water inlet pipe 3 and exit branch 4, cooling water enter
After water inlet manifold 5, further along water inlet pipe 3 into cooling water flow through in space with machine barrel outer wall carry out heat exchange, to machine barrel
Cooled, so that it is guaranteed that the continual and steady progress of extrusion process, completes the cooling water after heat exchange and flowed out to through exit branch 4
In outfall sewer 6, cooling circulation is completed.When extruding machine 1 is run, the extrusion screw of extruding machine 1 can be caused to material extruding acting
Temperature is gradually increasing in machine barrel, if cooled not in time to machine barrel, and will result in extruding machine 1 can not normal work, this reality
Developed with new cooling system based on the barrel configuration of extruding machine 1, coolant jacket 2 is arranged in extrusion screw acting heating in machine barrel
Position, enables machine barrel to realize overall cooling.The cooling water formed between coolant jacket 2 and machine barrel flows through space and is able to ensure that cooling water
