As the utility model further technical scheme, knot screen is the magnetic metal grate plate of a tool.
As the utility model further technical scheme, in the pipe of the horizontal direction of described feed pipe, be provided with at least two grids.
As the utility model further technical scheme, be connected with fin in described rotating shaft upper end.
Compared with prior art, an inverted "L" shaped feed pipe is set between scroll feeder and the charging aperture of double screw extruder in the utility model, and fan is set on the left of feed pipe, scraper plate is set in feed pipe.In reinforced process, the moisture carried in the raw materials such as Corvic is owing to being subject to the high temperature at twin-screw extrusion machine inlet capable place and the floating of evaporating, be subject to the effect of upper fan wind-force and directly blow out feed pipe, preventing condensation vapor to cause screw thread feeder discharging difficulty.On the other hand, the setting of feed arrangement both can prevent the situation of fed material from being blocked from occurring, improved powder feeding efficiency, and can carry out suitable preheating, improved the working (machining) efficiency in later stage.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of electric power cable of the utility model extrudes drawing-in device.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of electric power cable extrudes drawing-in device, comprises feed arrangement 2 and is arranged on feed arrangement 2 lower end and the screw feeder 1 be communicated with it; Described feed arrangement 2 comprises elevating hopper 22, and elevating hopper 22 lower end connects a hopper, is provided with knot screen 26 between elevating hopper 22 and hopper, and knot screen 26 is the magnetic metal grate plate of a tool, in order to remove the irony impurity in charging; The inwall of described elevating hopper 22 is provided with uniformly the twigs of the chaste tree 23 of some genesis analysis, is provided with heating tube 24 in the twigs of the chaste tree 32, heating tube 24, in order to carry out heating and dehumidification to charging, keeps its dry and mobility, so that following process; Helical blade 27 is provided with in described hopper, helical blade 27 is fixed on the rotating shaft 25 that is positioned in the middle part of hopper, the upper end of rotating shaft 25 is fixedly connected with by the inwall of fixed mount with elevating hopper 22, the lower end of rotating shaft 25 is provided with blender 28, rotated by blender 28 driven rotary axle 25, top material can be brought into the blender 28 of below by helical blade 27, has certain pressure simultaneously, can prevent fed material from being blocked when helical blade 27 discharges material; A feed pipe 3 falling overall L-shaped, circular in cross-section is provided with on the right side of described screw feeder 1.
Described feed pipe 3 bottom is connected with the charging aperture of double screw extruder 4, on the left of described feed pipe 3, outside is also provided with a fan 5, a rotating shaft 6 is provided with in the pipe of the vertical direction of described feed pipe 3, rotating shaft 6 is welded with a scraper plate 7, described rotating shaft 6 is also connected with the motor 8 being arranged on described feed pipe 3 top outer, the raw materials such as the Corvic in feed arrangement 2 are from entering in scroll feeder 2 bottom it, slowly fall in feed pipe 3, then enter in double screw extruder 4 and carry out extruding pelletization.The moisture carried in the raw materials such as Corvic evaporates owing to being subject to high temperature action, and from feed pipe 3 horizontal tube blowout feed pipe 3 under the effect of fan 5, the powder stocks such as the Corvic that feed pipe 3 inwall adheres to enter double screw extruder 4 smoothly because scraper plate 7 acts on;
In the pipe of the horizontal direction of described feed pipe 3, be provided with at least two grids 9, stop due to the effect of fan 5 and take raw material out of, reduce the harm to operational environment; Described scraper plate 7 and described feed pipe 3 inwall gap are 0.3*1mm, ensure scraper plate 7 can in feed pipe 3 normal rotary work.Scraper plate 7 completely and feed pipe 3 contact internal walls time, due to the material of adhesion, rotational resistance is larger.
Because scraper plate 7 and rotating shaft 6 are in feeding procedure, because heat trnasfer temperature can raise, fin 10 is connected with in described rotating shaft 6 upper end, described fin 10 is consistent with the center of described fan 5, fin 10 is in the sphere of action of fan 5, heat on scraper plate 7 and rotating shaft 6 is taken out of feed pipe 3 due to fin 10 by wind, reduces the temperature of scraper plate 7 and rotating shaft 6 self, prevents from scraper plate 7 and rotating shaft 6 adhere to the raw materials such as Corvic.
An inverted "L" shaped feed pipe is set between scroll feeder and the charging aperture of double screw extruder in the utility model, and fan is set on the left of feed pipe, scraper plate is set in feed pipe.In reinforced process, the moisture carried in the raw materials such as Corvic is owing to being subject to the high temperature at twin-screw extrusion machine inlet capable place and the floating of evaporating, be subject to the effect of upper fan wind-force and directly blow out feed pipe, preventing condensation vapor to cause screw thread feeder discharging difficulty.On the other hand, the setting of feed arrangement both can prevent the situation of fed material from being blocked from occurring, improved powder feeding efficiency, and can carry out suitable preheating, improved the working (machining) efficiency in later stage.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned execution mode, in the ken that one skilled in the relevant art possesses, various change can also be made under the prerequisite not departing from this patent aim.
