The second parallel double-screw formula structure is to adopt two parallel placement pair twists of screw rod to extrude to form.Some defectives that exist are for mainly being applicable to the raw material processing plastic pellet, so the scope of application is less; The barrel of this kind structure, screw rod require processing technology complicated, so production cost is higher, and the price of complete machine is higher; Barrel is provided with exhaust outlet, in process of production, produces easily the material situation of leaking; The pelletizing mode mainly adopts pelletizing after underwater cutpellet and the billot water cooling, so finished product particle water content is higher, and needing increases the heating, drying operation, has increased production cost.
The third long single-screw structure is that single screw rod, the barrel that draw ratio of employing is 20:1 forms, and barrel is provided with exhaust outlet.The defective that exists is that main motor current is bigger than normal, and the main frame cost increases and energy consumption increases; The screw rod barrel is longer, and the thermal treatment zone is more, and energy consumption is higher; Barrel is provided with exhaust outlet, in process of production, produces easily the material situation of leaking; Billot is cut into particle after cooling off through water tank, and the water content on plastic pellet surface is higher, makes lower road need to increase the heating, drying operation, has increased raw material user's production cost.
The utility model content
In order to solve the problems of above-mentioned existence, the utility model aims to provide the novel plastic granulation unit that a kind of energy consumption is low, efficient is high.
The utility model provides a kind of novel plastic granulation unit; comprise main engine bed, main motor, main gear reducer, barrel, screw rod, charging aperture, heating collar, filter, discharging opening die head, cooling roller device and hob type pelleter; wherein; described screw rod adopts reducing type, and the draw ratio of described screw rod and described barrel is 15:1.
Described filter is automatic draping formula filter, comprises flow distribution plate, filter cavity, bracing frame, drive sprocket, chain and reductor.
Described discharging opening die head is flat membrane type discharging opening die head.
Described cooling roller device is combined by many chill rolls, is used for cooling off described flat film.
Four or six detachable blades of described hob type pelleter employing add tool axis and form hob-cutter structure.
In the described novel plastic granulation unit that the utility model provides, its screw rod adopts reducing type to increase the service life of screw rod; The draw ratio of screw rod and barrel is the length that 15:1 has shortened the screw rod barrel, has changed the shape-designing of screw rod, has strengthened the flight pitch between screw rod, can make plastics sufficient plastifying fusion in machine barrel when heating; The discharging opening die head is that flat membrane type has been avoided the easily problem of fracture of single billot; Described cooling roller device is combined by many chill rolls, and chill roll adopts water circulating cooling in steel rider, and flat film does not contact with water straight, has effectively avoided the moisture defective of finished product plastic pellet; Four or six detachable blades of described hob type pelleter employing add tool axis and form hobboing cutter, replace the monoblock type cylinder knife that tradition is used, and make cost and the easy maintenance of hobboing cutter.
