Working principle:
before putting the waste roller into the tank body 1, a worker electrifies and starts the motor 2, the started motor 2 drives the second rotary rod 7 to rotate and drives the grinding disc 9 and the grinding plate 12 to rotate, at the moment, the worker puts waste plastic into the tank body 1 through the feed inlet 3, the rotating grinding plate 12 is matched with the first grinding block 14, the put waste plastic is ground and crushed, and as the space between the grinding plate 12 and the inner wall of the tank body 1 is gradually reduced, the waste plastic is continuously impacted and extruded along with continuous rotation and crushing, the volume of the waste plastic is gradually reduced, at the moment, the joint of the waste plastic and a screw (made of iron) is cracked, the waste plastic is separated from the screw, and then the crushed waste plastic and the detached screw fall from the space between the grinding plate 12 and the inner wall of the tank body 1; carrying out primary crushing on waste plastics;
meanwhile, the cover plate 13 is in threaded connection with the grinding disc 9, as the grinding plate 12 is continuously contacted with waste plastics with larger volume, the self-abrasion degree of the grinding plate 12 is gradually increased, the distance between the grinding plate 12 and the inner wall of the tank body 1 is gradually increased, waste plastics are insufficiently crushed, the effect of crushing waste plastics is further reduced, at the moment, workers can screw bolts, the cover plate 13 is moved out, the grinding plate 12 is lifted upwards along the sliding grooves 11 on the grinding disc 9, the grinding plate 12 with the same type is replaced to be installed on the grinding disc 9, and then the cover plate 13 is covered by bolts for fixing, so that the operation is convenient, the whole service life of the equipment is prolonged, and the self-abrasion degree of the grinding plate 12 is reduced;
the waste plastics subjected to primary crushing and the separated screws fall down to the center of the corrugated plate 18 under the action of the annular baffle plate 16, the volume of the plastics subjected to primary crushing is larger than the inner diameter of the holes 21, the situation that the waste plastics fall into the cavities of the corrugated plate 18 is avoided, and the screening effect of the screening assembly is improved; when the waste plastic falls on the corrugated plate 18, the detached screws fall into the cavity of the wave stabilizing plate through the holes 21, and then are discharged through the discharge port 22 along the inclined plane at the bottom of the corrugated plate 18;
meanwhile, the rotating second rotating rod 7 drives the scraping rod 17 to rotate, the rotating scraping rod 17 scrapes on the surface of the corrugated plate 18, waste plastics on the surface of the corrugated plate 18 are stirred in the scraping process, so that the waste plastics are pushed from the center to the periphery, and screws which are separated from the waste plastics are mixed between the waste plastics in the pushing process of the waste plastics, fall from the waste plastics under the driving of the scraping rod 17 and fall into the corrugated plate 18 from the holes 21, so that the screening effect of the waste plastics and the screws is realized; the waste plastics pushed to the periphery drop into the fine crushing assembly from the corrugated plate 18 and the notch on the inner wall of the tank body 1, and the waste plastics are further crushed to reduce the volume;
then, the waste plastics which are not screened by the screening component fall onto the fixed plate 23 from the notch of the screening component and roll down along the inclined plane of the fixed plate 23 towards the rotating disc 24, and compared with the waste plastics which are put in, the crushed waste plastics have smaller volume, are easier to crush and have high uniformity of crushed waste plastic particles; at this time, the rotating disc 24 rotates together with the second grinding block 25 to carry out secondary crushing and grinding on the fallen waste plastic particles, and the space between the rotating disc 24 and the fixed plate 23 is gradually reduced, so that the volume of the waste plastic is gradually crushed and ground to be smaller, and meanwhile, the rotating disc 24 and the second grinding block 25 are continuously contacted with the waste plastic, so that the contact area between the second grinding block 25 and the waste plastic is increased, and the waste plastic particles are fully crushed and ground;
the broken waste plastic falls into the L-shaped groove 26 through the minimum distance between the rotary disk 24 and the fixed plate 23, and the rotary disk 24 drives the scraping plate 27 in the L-shaped groove 26 to rotate at the moment, so that the waste plastic in the L-shaped groove 26 is pushed, and the waste plastic is discharged and collected from the discharge hole 28 in the pushing process, so that the subsequent work is performed.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be appreciated by persons skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention.
