Described heater is two, and wherein primary heater is installed on the machine barrel between feed hopper and the vaccum exhaust outlet, and secondary heater is installed on the machine barrel between vaccum exhaust outlet and the cooling water tank.
The screw propulsion screw rod is formed with reducer by isometrical section, forms feeding section, the softening section of first reducing, exhaust section, the softening section of second reducing, metering section respectively, and it is provided with isometrical, equidistant helical blade.
The string that will meet formed pipe requirement and process glue mixing adds from loading hopper, after material enters the machine of being extruded to shape, under screw rod rotation extruding, through feeding section, the softening section of first reducing enters exhaust section, exhaust section connects Minton dryer, material is extremely zero or negative pressure at the pressure drop of exhaust section, the volatile matter of the gas of pressurized and vaporization directly discharges from material in the material, gas is taken away by vavuum pump by exhaust outlet, make material moisture be no more than 5%, through removing the material of gas and volatile matter, after the second softening section compression is softening, pass through shaper again.Constantly push convey materials backward through screw rod, form bobbin under the power that is squeezed in the gap between shaper and the machine tube inner wall effect.
Description of drawings
Accompanying drawing is depicted as structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, be disposed with loading hopper 23, heater, vaccum exhaust outlet 27 and cooling water tank 31 on machine barrel 26 outer walls of this extrusion forming device, be provided with screw propulsion screw rod 24 in the inner chamber of machine barrel 26, screw propulsion screw rod 24 is formed with reducer by isometrical section, form feeding section, the softening section of first reducing, exhaust section, the softening section of second reducing, metering section respectively, it is provided with isometrical, equidistant helical blade, and this structure is identical with the screw-rod structure of second order exhaust plastic extruder.Certainly also can adopt a stepwise or twin-screw, multiscrew structure, at this moment not need to be provided with vacuum pumping hardware certainly.The front end of screw propulsion screw rod 24 connects with motor 21 by transmission device 22.The rear end of screw propulsion screw rod 24 is fixed with shaper 30, and this shaper 30 is a cylinder, and its outer surface is provided with annular groove, and described shaper 30 is the wall thickness of bobbin with the diameter difference of described machine barrel 26.Annular groove helps fiber lamination, lamination in the bobbin forming process.The front end of described shaper 30 is connected with screw rod 24 rear ends by adjusting nut 29.Described machine barrel 26 is a fabricated structure, is made up of three pipeline sections, and adjacent tubular segments is fixedly connected by flange, and described cooling water tank 31 is installed on the pipeline section of rear portion, and shaper 30 is arranged in the inner chamber of postmedian pipeline section, and screw propulsion screw rod 24 is positioned at anterior pipeline section inner chamber.Described heater is two, and wherein primary heater 25 is installed on the machine barrel 26 between feed hopper 23 and the vaccum exhaust outlet 27, and secondary heater 28 is installed on the machine barrel 26 between vaccum exhaust outlet 27 and the cooling water tank 31.
Its operation principle is: the string that will meet formed pipe requirement and process glue mixing adds from loading hopper 23, after material enters the machine of being extruded to shape, be under 60 rev/mins the second order exhaust list screw rod rotation extruding at rotating speed, through feeding section, the softening section of first reducing enters exhaust section, exhaust section connects Minton dryer, material is extremely zero or negative pressure at the pressure drop of exhaust section, the volatile matter of the gas of pressurized and vaporization directly discharges from material in the material, gas is taken away by vavuum pump by exhaust outlet, make material moisture be no more than 5%, through removing the material of gas and volatile matter, again after the second softening section compression is softening, by shaper 30.Constantly push convey materials backward through screw rod, form bobbin under the power that is squeezed in the gap between shaper and the machine tube inner wall effect.Because the shaper outer wall is provided with annular groove, and is thicker herein in the forming process, passes through the extruding at the slightly little place of diameter again, can make fiber form lamination, lamination, thereby reach certain density and intensity, just can finalize the design.
In type-approval process, material is under the screw acting of rotation, be fed forward and compacting, the rubbing action of machine tube inner wall and screw surface produces certain heat down, and storeroom also generates certain frictional heat in the process of advancing simultaneously, passes through the machine barrel external heat again, 120 ℃ of the first softening section external heat temperature, 150 ℃ of the second softening section external heat temperature like this through twice heating and vacuum exhaust, finally just can reach the softening condition that needs of lignin.String is the entity that is made of cellulose, hemicellulose and three kinds of main components of lignin, and the lignin important part that is it, lignin is present in the cell membrane and intercellular layer of fiber, intersperse among around the fiber, fiber is binded mutually and fixed, it is amorphous polymer, its key character has the vitrifying characteristic, lignin is softening when being heated to the glass transition temperature of lignin, condensation reaction takes place, plasticity becomes and becomes better and better, and hot pressing promotes down to bind mutually, interweave between fiber, thereby softens into the software shape.Softening material continuously is fed forward by screw rod, pass through shaper without barrier, form the bobbin shape, cooled off the machine barrel outer wall by the cooling water in the cooling water tank 31 this moment again, be cooled to 110 ℃ of temperature, make fiber reach certain condensation intensity, finally be extruded into bobbin shape string pipe.
