In the use of this embodiment, preferably, as shown in fig. 3, the screen 4 is slidably connected in the supporting frame 30, the two lateral walls of the supporting frame 30 are respectively provided with the slide ways 31, as shown in fig. 8, one longitudinal side of the screen 4 is fixedly connected with the rectangular toothed frame 33, and the rectangular toothed frame 33 is slidably connected in the second slide cavity 32 arranged in the supporting frame 30, after the plastic recovery device is started to work, the screening motor 35 is controlled by the screening motor 35 controller to work synchronously (the screening motor 35 is electrically connected with an external power supply), the screening motor 35 drives the half gear 34 to rotate, and then the half gear 34 drives the rectangular gear frame 33 to move rapidly back and forth in the second sliding cavity 32, thereby driving the screen 4 to rapidly reciprocate in the supporting frame 30 along the slide way 31, so that the plastic filtered on the screen 4 with larger particles can rapidly roll off from the screen 4 to the recycling discharge port 7.
Seventh embodiment, on the basis of the first embodiment, the recycling discharging hole 7 includes a discharging channel 36 communicated with the screening box 3, and a telescopic plate 37 is slidably connected in the discharging channel 36, and the telescopic plate 37 is connected with the discharging channel 36 through a connecting spring 38, and second trigger inclined blocks 39 matched with the first trigger inclined blocks 11 are respectively arranged on two longitudinal sides of one end of the telescopic plate 37, which is arranged outside the discharging channel 36.
In the use of this embodiment, as shown in fig. 4, preferably, we slidably connect a telescopic plate 37 in the discharging channel 36, when in an initial state, the screened plastic falls into the recycling bin 8 through the discharging channel 36 and the telescopic plate 37, the telescopic plate 37 is located above the recycling bin 8 and partially overlaps with the recycling bin 8, the telescopic plate 37 is arranged such that the plastic falling from the discharging channel 36 can completely fall into the recycling bin 8 without falling on the ground, when the recycling bin 8 is driven by the circulating lifting mechanism to move upwards, the two first triggering inclined blocks 11 fixed on the recycling bin 8 extrude the telescopic plate 37 into the discharging channel 36 by extruding the second triggering inclined block 39 fixedly installed on the telescopic plate 37 and cross the telescopic plate 37 under the driving of the circulating lifting mechanism, when the recycling bin 8 crosses the telescopic plate 37, the telescopic plate 37 is ejected outwards under the elastic force of the connecting spring 38 and returns to the initial state, it is worth noting here that: when the recycling bin 8 is driven by the circulating lifting mechanism to extrude the retractable plate 37 to the discharging channel 36 and move upwards, the retractable plate 37 is not enough to overcome the torsion force of the torsion spring 29 under the elastic force of the connecting spring 38 (i.e. the retractable plate 37 abuts against the movable door 10 and cannot push the movable door 10 to rotate towards the recycling bin 8);
the longitudinal length of collection box 8 is greater than the longitudinal length that the ejection of compact said 36 and be less than the longitudinal length of retrieving feed inlet 9 in this scheme to guarantee that the great plastics of granule that come out in the ejection of compact way 36 can fall into completely to collection box 8 in, make the plastics in collection box 8 can fall into completely to retrieving feed inlet 9.
In an eighth embodiment, on the basis of the first embodiment, the driving device includes a first pulley 40 rotating coaxially with the crushing roller, and a second pulley 41 is engaged with the first pulley 40 located on the same side in the lateral direction, the second pulley 41 is driven by a crushing motor 43 fixed on the crushing box 1, and the two first pulleys 40 and the second pulley 41 engaged with each other are connected by a toothed belt 42.
When the embodiment is used, the crushing motor 43 drives the two first pulleys 40 positioned on the same lateral side to rotate through the second pulley 41 so as to drive the first crushing roller 5 and the second crushing roller 6 positioned on the same lateral side to rotate along the clockwise direction, the other crushing motor 43 drives the two first pulleys 40 positioned on the other lateral side to rotate through the second pulley 41, and then drives the first crushing roller 5 and the second crushing roller 6 positioned on the other lateral side to rotate along the counterclockwise direction, so that the effect of crushing the plastic products is realized.
Two groups of crushing rollers are arranged in the crushing box 1 of the plastic recovery device, the crushing teeth of the two groups of crushing rollers are different in size, the crushing teeth of the upper group of crushing rollers are larger, so that plastic products with larger volume can be firstly crushed preliminarily, and the crushing teeth of the lower group of crushing rollers are smaller, so that the plastic products can be secondarily crushed further, and the plastic products can be crushed more uniformly;
in order to prevent the plastic products with larger particles from blocking the screen 4, the screen 4 is driven by the screening motor 35 to rapidly move back and forth in the bearing frame 30, so that the plastic products with larger particles falling onto the screen 4 can rapidly roll off from the screen 4 to the recycling discharge port 7 and enter the recycling box 8 through the recycling discharge port 7;
when the circulating lifting mechanism drives the recycling bin 8 to move to the position of the trigger device, a first trigger inclined block 11 fixedly arranged on the recycling bin 8 is in contact with the trigger device, a movable door 10 rotatably installed on one side of the recycling bin 8 is opened, large plastic in the recycling bin 8 falls into a recycling feed inlet 9 and enters the recycling bin 1 again, and the plastic is further crushed, so that particles are more uniform.
The above description is only for the purpose of illustration, and it should be understood that the present invention is not limited to the above embodiments, and various modifications conforming to the spirit of the present invention are within the scope of the present invention.
