Description
Technical field
The utility model relates to a kind of extruder, relates in particular to a kind of screw extruder.
Background technology
Screw extruder is widely used in plastics, the manufacture field of materials such as rubber, it is the important plant equipment of macromolecular material manufacturing and processing and forming, because plastics, rubber is of a great variety, performance is different, because, re-use screw extruder and add man-hour, determine processing conditions, machined parameters particular importance in order to obtain high performance product.There is a Chinese utility model patent to disclose the utility model patent of title " a kind of single screw extrusion machine that flow plug is set " at present, the day for announcing is 2001.08.01, notification number is 1305888, the present invention is a kind of single screw extrusion machine that flow plug is set, joint portion at machine barrel outlet and head is provided with flow plug, it is horn-like through-hole structure, its through hole sectional area is with per hour per kilogram extrusion capacity calculating, be arranged on 0.3-1mm#+[2] between, flow plug is 0 °-10 ° near the angular range between the angled end-face B of the end face A of screw head and screw head, spacing is 2-8mm, and at the port of export 50-500mm place of distance machine barrel cooling device is set.The hard density height of product that the present invention makes, anti-aging can utilize high molecular weight resin production, and the plant equipment investment is little, obvious energy conservation.Owing to be to get between screw rod and the screw sleeve after material is heated into the viscosity flow material gradually, and produce variation of temperature during screw rod work, and owing to the requirement to properties of product, often require to remain on certain scope to the temperature of screw rod and screw sleeve, generally be to surpass certain temperature, and this design just can not overcome this defective, can not reduce the temperature of screw sleeve effectively.
Goal of the invention of the present utility model has been to provide a kind of hair-dryer that is provided with on screw sleeve to control screw extruder with the temperature of adjusting screw(rod) and screw sleeve.
Of the present utility model solving the problems of the technologies described above by following technical proposals solved: a kind of screw extruder, comprise screw sleeve, the circumference of described screw sleeve is provided with hair-dryer, described hair-dryer comprises fan housing and air blast, fan housing is fixed on the circumference of screw sleeve, and the fan housing top is provided with exhaust outlet, and the fan housing below is an air blast.
The quantity of described hair-dryer is 5 to 7.
Described screw sleeve is provided with temperature sensor, and temperature sensor links to each other with temperature controller, the switch of temperature controller control motor.
So the utlity model has the advantage that to control screw rod and screw sleeve temperature well.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model.
Fig. 2 cuts open the enlarged drawing of attempting for the A-A of hair-dryer among Fig. 1.
The specific embodiment
Below by embodiment, and, the technical solution of the utility model is described in further detail in conjunction with the accompanying drawings 1 to accompanying drawing 2.
Embodiment, a kind of screw extruder, comprise frame 6 and gearbox 8, the power transmission shaft of gearbox 8 links to each other with screw sleeve 4 by the axle coupling, be with screw rod 9 in the screw sleeve 4, material is got between screw rod 9 and the screw sleeve 4 after being heated into the viscosity flow material gradually, on the circumference of described screw sleeve 4, be set with if 7 hair-dryers, hair-dryer comprises fan housing 3 and air blast 10, fan housing 3 is fixed on the circumference of screw sleeve 4, and fan housing 3 tops are provided with exhaust outlet 2, fan housing 3 belows are air blast 10, and air blast 10 links to each other with motor 5.In order more effectively automatically to control the temperature of screw rod 9 and screw sleeve 4, the compartment of terrain is provided with temperature sensor 1 on screw sleeve 4, and temperature sensor 1 links to each other with temperature controller 7, by the switch of temperature controller 7 control motors 5.
Claims (3)
1, a kind of screw extruder, comprise screw sleeve (4), the circumference of described screw sleeve (4) is provided with hair-dryer, it is characterized in that described hair-dryer comprises fan housing (3) and air blast (10), fan housing (3) is fixed on the circumference of screw sleeve (4), and fan housing (3) top is provided with exhaust outlet (2), and fan housing (3) below is air blast (10).
