Detailed description of the invention
Core of the present utility model is to provide a kind of forced feed compression set, and this forced feed compression set can realize carrying out feeding to fluffy material easily.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See the structural representation of the forced feed compression set that Fig. 1, Fig. 1 provide for the utility model embodiment.As can be seen from Figure 1, the forced feed compression set that the utility model embodiment provides mainly comprises housing 1 and screw rod 2, and housing 1 has through hole, and screw rod 2 is placed in the through hole of housing 1, and the two ends of through hole are respectively feed end 3 and discharge end 4.
The spiral groove depth being in feed end 3 place due to every root screw rod 2 is greater than the spiral groove depth that it is in discharge end 4 place, then define certain compression ratio between charging place being in feed end 3 place of screw rod 2 and discharging place being in discharge end 4 place.During work, screw rod 2 is connected with drive unit, fluffy material (as carbon fiber, glass fibre, aramid fiber etc.) enters from the charging aperture of forced feed compression set, then realize carrying out enforce compression to fluff material under the driving of drive unit, fluffy Material compression is become closely knit material, and the material after compression from discharging opening out.Mixed with other materials again by the fluff material of compression compact and add will become in double screw extruder relatively easy, thus achieve feeding is carried out to fluffy material.The forced feed compression set that certain the utility model embodiment provides not only can process the above-mentioned three kinds of materials mentioned, and it can process the various more fluffy and short fiber material that volume is larger.
Above-mentioned said " charging place " is occlusion place that screw rod 2 is in feed end 3 place, and " discharging place " is occlusion place that screw rod 2 is in discharge end 4 place.Charging place mentioned below and discharging place are also indication above.
The screw rod 2 of forced feed compression set is connected with gearbox, and gearbox is connected with servomotor, by adjustment motor adjusting rotary speed, after changing the size of feeding capacity, can produce the various short fiber composite high-molecular materials of different proportion.The type of drive except motor drives can certainly be adopted.
As shown in Figure 1, two screw rods 2 can be provided with, and the spiral groove depth that every root screw rod 2 is in feed end 3 place is in discharge end 4 place spiral groove depth to it reduces gradually, such structural design can so that the processing of screw rod, and material is sentenced uniform ratio and compressed from the charging of screw rod to discharging, add the uniformity of material after processing.And can be 1:2 or 1:3 etc. to the ratio of the compression of material between charging place and discharging place.
Certainly, the quantity of screw rod 2 is also not limited to two, can be set to three.And be also not limited to spiral groove depth that every root screw rod 2 is in feed end 3 place is in discharge end 4 place spiral groove depth to it and reduce gradually, it specifically can be designed as one or two or three.And its spiral groove depth being in feed end 3 place is in discharge end 4 place spiral groove depth to it also not necessarily reduces gradually, can be designed as the spiral groove depth that screw rod 2 is in feed end 3 place and be greater than the spiral groove depth that it is in discharge end 4 place, but part spiral groove depth can be had in the middle of screw rod 2 to be in the less situation of the spiral groove depth at discharge end 3 place than it.
