[0002] Plastics are polymer compounds that are polymerized from monomers through addition polymerization or condensation polymerization. Microplastics are harmful to human health. They have a medium deformation resistance, between fiber and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The main component of plastics is resin. Resin refers to a polymer compound that has not yet been mixed with various additives. The term resin was originally named after the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of plastics. The basic properties of plastics are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or little additives, such as plexiglass.

[0035] The present invention also proposes a drying method for a conveying and drying mechanism of a plastic pelletizer, comprising the following steps: S1: Pour the plastic to be pelletized into the receiving hopper 4 and then enter the crushing box 2, the plastic is pelletized by the crushing roller 5, and the plastic is screened by the sieve plate 6. The plastic with qualified shape and size will fall to the bottom of the crushing box 2, and the unqualified plastic will be discharged from the discharge port; S2: By opening the solenoid valve 3, the qualified plastic in the crushing box 2 will enter the drying barrel 12, and by starting the hot air blower 8 and the motor 11, the drying barrel 12 will be driven to rotate by the rotation of the output shaft of the motor 11, and the plastic in the drying barrel 12 will be stirred by the cooperation of the drying barrel 12 and the stirring rod 13, and the hot air will be transmitted to the air outlet plate 9 through the hot air blower 8, and then discharged through the air outlet plate 9 to dry the plastic in the drying barrel 12; S3: By starting the fan 16, the fan 16 drives the air to circulate and drives the floating objects in the drying box 1 to move into the filter box 14, and the floating objects are intercepted and filtered by the filter plate 15.
[0036] Working principle: In actual use, when it is necessary to pelletize and dry the plastic, pour the plastic to be pelletized and dried into the feed hopper 4, and start the crushing roller 5. At this time, the two crushing rollers 5 rotate to pelletize the plastic, and the pelletized plastic will fall onto the screen plate 6. The size of the plastic will be screened by the screen plate 6, and the plastic that does not meet the size will be discharged from the right side of the crushing box 2. When the screen plate 6 needs to be replaced, first push the rotating rod 17 to rotate. At this time, the rotation of the rotating rod 17 will drive the lifting plate 20 to move downward. When the lifting plate 20 moves downward, it will drive the vertical rod 19 to move downward. When the vertical rod 19 moves, it will drive the limit frame 22 to move downward. When the limit frame 22 moves downward, it will drive the block 23 to move downward. When the limit frame 22 moves, it will compress the push spring 21. At this time, the limit frame 22 and The blocks 23 are respectively out of contact with the outer wall and the slot of the sieve plate 6, so that the sieve plate 6 is unlocked. At this time, the sieve plate 6 can be pulled out for replacement, and the sieve plate 6 with a suitable mesh size is inserted into the crushing box 2, and the slot is aligned with the blocks 23. At this time, the rotating rod 17 is pushed to rotate, and the rotation of the rotating rod 17 will drive the lifting plate 20 to move up and reset. At the same time, the spring 21 is pushed to push the limit frame 22 to move up and drive the vertical rod 19 to move up and reset. The vertical rod 19 is limited by the connecting plate 18, so that the vertical rod 19 and the limit frame 22 can move vertically stably, and the sieve plate 6 is limited by the limit frame 22. The sieve plate 6 is fixed by the engagement of the blocks 23 with the slots, so that the sieve plate 6 remains stable during use, and the screened plastic will fall to the bottom of the crushing box 2. By opening the solenoid valve 3 The crushed materials can fall into the drying barrel 12 in the drying box 1. At this time, the motor 11 and the hot air blower 8 are started, and the hot air generated by the hot air blower 8 is evenly blown out through the air outlet plate 9, so as to dry the plastic in the drying barrel 12. The rotation of the output shaft of the motor 11 will drive the drying barrel 12 to rotate. The rotation of the drying barrel 12 cooperates with the stirring rod 13, so as to facilitate the stirring of the plastic in the drying barrel 12, so that the plastic is heated evenly. When it is necessary to remove dust from the inside of the drying box 1, by starting the fan 16, the motor 16 drives the air circulation, so that the dust blown by the hot air in the drying box 1 enters the filter box 14, and the dust is intercepted and filtered by the filter plate 15, which is convenient for cleaning and collection. When the filter plate 15 is needed, When cleaning, by pushing the control plate 24 to move right, the control plate 24 will drive the transmission plate 25 to move right when it moves, and the movement of the transmission plate 25 will drive the transmission shaft 27 to move horizontally. At the same time, the movement of the transmission plate 25 will compress the return spring 26, causing the return spring 26 to deform and store force. At this time, the movement of the transmission shaft 27 will slide in the transmission groove, thereby pushing the limit rod 28 to rotate. At this time, the two limit rods 28 rotate to the side away from each other. When the limit rod 28 rotates, it will drive the torsion spring 29 to deform and store force. When the limit rod 28 moves, it will drive the ball to move and disengage from the filter plate 15, thereby unlocking the filter plate 15. At this time, the filter plate 15 can be pulled out for cleaning or replacement. When installing the filter plate 15, insert the filter plate 15 into the filter box 14, and then release the control plate 24.The reset spring 26 loses its restriction and pushes the control plate 24 to move horizontally and reset. At the same time, the reset spring 26 pushes the transmission plate 25 to move leftward and reset. The transmission plate 25 moves leftward and drives the transmission shaft 27 to reset. The transmission shaft 27 drives the transmission slot to drive the two limit rods 28 to rotate. At the same time, the two torsion springs 29 rotate and reset to drive the two limit rods 28 to reset. At this time, the limit rod 28 drives the ball to move, and the filter plate 15 is pressed and limited by the ball, so that the filter plate 15 can be replaced.
