Technical field

The utility model relate to a kind of be used for the broken worn-out plastics, to recycle the broken drawing-in device of waste or used plastics again.

Background technology

At present, the range of application of plastic products more and more widely, and the discarded object of plastics is not perishable, accumulates over a long period, and can have a strong impact on the ecological environment of the earth.Therefore, people have expected with the plastic refuse reclaiming, to reuse.Utilize disintegrating machine with waste plastic be broken into piece material, again piece material is sent to screw extruder pelletizer again granulation be one of method of at present the most frequently used recovery plastics.Present employed disintegrating machine all is horizontal, volume is huger, the primary structure of its breaker is: broken hopper is installed on frame, in broken hopper, be provided with moving knife and stationary knife, moving knife is installed on the rotor shape knife rest, the two ends of rotor shape knife rest are installed on the frame by bearing respectively, stationary knife is fixedly mounted on the broken hopper sidewall, motor waits by belt and belt pulley and drives the knife rest rotation, upper end at broken hopper is provided with charging aperture, is provided with discharging opening in the bottom of broken hopper; During work, rotor shape knife rest and moving knife rotate under the driving of motor, just form mutual cutting action between moving knife and the stationary knife; The plastics of need fragmentation are put into the broken hopper from charging aperture, and under the acting in conjunction of moving knife and stationary knife, plastics are cut into piece material, and piece material is collected after falling down from the bottom discharge mouth.And then the piece material of collecting joined by the spiral feeder in the hopper of screw extruder pelletizer, by screw extruder pelletizer granulation again.The shortcoming of the breaker of said structure is: one, volume is bigger, and it is bigger to take up room; Two, can't be directly and screw extruder pelletizer link into an integrated entity, also need to be equipped with in addition equipment such as spiral feeder, suction pipeline, equipment investment cost is bigger.

Summary of the invention

At the problems referred to above, the utility model will provide a kind of volume plastics less, that can directly be connected with screw extruder pelletizer broken drawing-in device.

For achieving the above object, the technical solution adopted in the utility model is: the broken drawing-in device of described plastics mainly comprises: base, and main shaft is arranged in the base by bearing; Upside at base is provided with broken hopper, and the upper end of main shaft extend in the broken hopper, is fixed with knife rest in the upper end of main shaft, is fixed with moving knife on the knife rest; On the sidewall of broken hopper, stationary knife is installed, on the sidewall of broken hopper, also is provided with discharging opening.

The further technical scheme of the utility model is: also be provided with the helical form stock guide on the inwall of broken hopper, the lower end of stock guide is near discharging opening.

A kind of further technical scheme of the utility model is: the top at broken hopper also is connected with casing drum.

The utility model has the advantages that: the broken drawing-in device of plastics described in the utility model can directly be connected with screw extruder pelletizer; can save equipment such as spiral feeder, suction pipeline; reduced cost of investment, reduced the occupation of land space, also can increase work efficiency greatly.

Embodiment

Below in conjunction with the drawings and specific embodiments technical scheme described in the utility model and operation principle thereof and advantage are further described.

As shown in Figure 1 and Figure 2, the broken drawing-in device of plastics described in the utility model mainly comprises: base 2, and main shaft 3 is arranged in the base 2 by bearing; Upside at base 2 is provided with broken hopper 6, and the upper end of main shaft 3 extend in the broken hopper 6, is fixed with knife rest 16 in the upper end of main shaft 3, and in the present embodiment, pressing plate 4 is fixedly mounted on knife rest 16 on the main shaft 3; Be fixed with moving knife 15 on the knife rest 16, in the present embodiment, moving knife cover plate 14 is fixed on moving knife 15 on the knife rest 16; Stationary knife 13 is installed on the sidewall of broken hopper 6, and in the present embodiment, stationary knife 13 is fixedly mounted on the stationary knife mount pad 17, on the broken hopper 6 of stationary knife mount pad 17 fixed installations; On the sidewall of broken hopper 6, also be provided with discharging opening 5.In the present embodiment, also be provided with sheath 7 in the periphery of broken hopper 6, one of effect of sheath 7 is to protect stationary knife 13 and stationary knife mount pad 17.As Fig. 1, shown in Figure 3, in the present embodiment, on the inwall of broken hopper 6, also be provided with helical form stock guide 12, the lower end of stock guide 12 is near discharging opening 5.As shown in Figure 1, in the present embodiment, also be connected with casing drum 8 at the top of broken hopper 6; Casing drum 8 flexibly connects by hinge 11 and broken hopper 6; Be provided with also on the sidewall of casing drum 8 that watch window 10---the effect that watch window 10 is set is: can observe the working condition in casing drum 8 and the broken hopper 6 at any time; In addition, be provided with also on the sidewall of casing drum 8 that hole for water spraying 9---the effect that hole for water spraying 9 is set is: when the material in the broken hopper 6 because of cutting friction temperature when too high, can be from hole for water spraying 9 in the broken hopper 6 spray cooling.

As Fig. 4, shown in Figure 5; be that the broken drawing-in device of plastics described in the utility model specifically is applied to the structural representation on the screw extruder pelletizer; that is: base 2 is installed on the support 20 of screw extruder pelletizer 18; discharging opening 5 is connected with the charging aperture of screw extruder pelletizer 18, and the motor 19 that is installed on the support 20 can come drive shaft 3 by belt wheel 21 and belt (not shown) and belt wheel 1.

The operation principle of the broken drawing-in device of the plastics of said structure is: at first actuating motor 19, make main shaft 3 rotations, main shaft 3 drives knife rest 16 and moving knife 15 rotations again, like this, just formed the action of mutual cutting between moving knife 15 and the stationary knife 13, in casing drum 8, add the plastics thing piece that needs fragmentation, plastics thing piece is under the acting in conjunction of moving knife 15 and stationary knife 13, be cut into piece material, because moving knife 15 and knife rest 16 are in ceaselessly rotation, piece material also can and then rotate in broken hopper 6, therefore, under action of centrifugal force, piece material will be run out of from discharging opening 5, after being provided with helical form stock guide 12 on the inwall of broken hopper 6, rotating piece material can be more prone to run out of from discharging opening 5 under the guiding of stock guide 12.When the broken drawing-in device of described plastics with after screw extruder pelletizer is connected; piece material will directly enter into the charging aperture of screw extruder pelletizer from discharging opening 5, proceed next procedure incessantly by screw extruder pelletizer---spiral extruding pelletization operation.

From the above mentioned as can be known; the broken drawing-in device of plastics described in the utility model can directly be connected with screw extruder pelletizer; not only can save equipment such as spiral feeder, suction pipeline; reduce cost of investment; reduce and take up an area of the space; also can reduce working link, make the continuity of whole production technology better, improve operating efficiency.
