As shown in fig. 15, the a snap ring 52 is located between the external thread 53 and the outer shaft of the a telescopic shaft 13; as shown in fig. 5, a strainer 29 is installed at the inlet of the drain pipe 27; the outer diameter of the spiral piece 48 is equal to the inner diameter of the conveying cylinder 4, and as shown in fig. 12, the other half of the spiral piece 48 near the bottom of the conveying cylinder 4 is uniformly provided with weep holes 49.

The specific working process is as follows: as shown in fig. 13, when the plastic processing is not performed, the head end of the external thread 53 just matches with the thread of the thread bush a, the tension spring a 55 is in a pre-tensioned state, the tension spring B60 is in a natural state, and the tail end of the spiral piece 48 is positioned at the bottom of the conveying cylinder 4. As shown in fig. 12, the piston 40 is spaced from the bottom of the barrel 12 and the barrel 12 is empty of adjuvant.

The electric valve 28 controlling the water inlet pipe 26 is opened to fill the bottom of the delivery cylinder 4 with a certain amount of clear water, and then the electric valve 28 controlling the water inlet pipe 26 is closed. When the electric drive 8 is started for plastic treatment, a certain amount of waste plastic is poured into the crushing shell 25. The electric driver 8 drives the shaft A20, the gear A18 and the crushing roller A17 to rotate through the shaft C23, the chain B22, the chain 21 and the chain wheel A19, the gear A18 drives the crushing roller B14 to rotate through the gear B16 and the shaft B15, the crushing roller A17 and the crushing roller B14 are matched to crush waste plastics, crushed waste plastics enter the bottom of the conveying cylinder 4 through the horn tube 6, and a large amount of liquid remained in a waste plastic bottle flows into the bottom of the conveying cylinder 4 after being crushed. The electric driver 8 drives the spiral piece 48 to rotate forward through the C shaft 23, the C bevel gear 24, the A bevel gear 47, the A telescopic shaft 13 and the sliding shaft 46, the forward rotating spiral piece 48 has a spiral downward thrust force on water and plastics at the bottom of the conveying cylinder 4, and the stirring piece 50 rotating along with the spiral piece 48 stirs and cleans the plastics floating on the water. During the period, the B telescopic shaft 32 and the B bevel gear 33 rotate synchronously along with the sliding shaft 46; the bevel gear B33 drives the D shaft 37 and the screw rod 36 to rotate forward through the bevel gear D34 and the guide key 38, the screw rod 36 rotating forward is in threaded fit with the thread of the thread sleeve B9 to enable the D shaft 37 to move upwards along the axial direction, the D shaft 37 drives the piston 40 to move upwards to enable the hose A44 to absorb the auxiliary agent from the container containing the auxiliary agent and convey the auxiliary agent into the charging barrel 12 through the one-way valve 42; since initially piston 40 is at a distance from the bottom of barrel 12 and no adjuvant is present in barrel 12, the adjuvant that enters barrel 12 does not completely fill the space formed between barrel 12 and piston 40. The piston 40 which moves upwards continuously is separated from the top end of the barrel 12, so that after the piston 40 is separated from the top end of the barrel 12, the barrel 12 cannot suck the auxiliary agent continuously and the auxiliary agent does not occupy the whole barrel 12 at the moment, and the auxiliary agent is prevented from being spilled out of the barrel 12 due to the vibration of a machine; the amount of auxiliary agent in the barrel 12 now corresponds exactly to the amount of waste plastic being processed.

When the inner shaft of the A telescopic shaft 13 rotates forwards, the external thread 53 is matched with the thread of the A thread sleeve 45, so that the inner shaft of the A telescopic shaft 13 moves towards the conveying cylinder 4 along the axial direction of the inner shaft, the inner shaft of the A telescopic shaft 13 pushes the sliding shaft 46 and the spiral sheet 48 to move towards the B telescopic shaft 32, and the inner shaft of the B telescopic shaft 32 retracts; during the period, the A clamping ring 52 and the B clamping ring 57 move synchronously along with the inner shaft of the A telescopic shaft 13, the A ring 51 moves synchronously along with the A clamping ring 52, the B ring 56 moves along with the B clamping ring 57, the A tension spring 55 gradually restores to a natural state, and the B tension spring 60 is gradually stretched; the slide 54 ensures that the a-ring 51 and the B-ring 56 do not rotate while moving. When the tail end of the external thread 53 is just disengaged from the thread insert 45A, the tension spring 55A is in a natural state, the tension spring 60B is in a stretched state, and the movement amount of the inner shaft of the telescopic shaft 13A reaches the maximum. The screw plate 48 moving towards the direction of the B telescopic shaft 32 enables the tail end of the screw plate to have a certain distance from the bottom of the conveying cylinder 4, so that plastics continuously subjected to the downward pushing force of the screw in a slant direction are prevented from blocking the bottom of the conveying cylinder 4, and the plastics and water can be stirred and cleaned conveniently.

After the waste plastics are quantitatively cleaned, an electric control valve 28 for controlling a drain pipe 27 is opened, so that water at the bottom of the conveying cylinder 4 is discharged through the drain pipe 27 and recycled into a recycling tank, and the plastic is effectively isolated in the conveying cylinder 4 by a filter screen 29; the electric valve 28 of the water discharge pipe 27 is closed after the water is discharged. The electric driver 8 is controlled to reversely rotate in the drainage process, and the electric driver 8 reversely rotates the A telescopic shaft 13, the sliding shaft 46, the spiral piece 48, the B telescopic shaft 32 and the B bevel gear 33 after a series of transmissions. Because the tension spring 60B is in a stretching state and the inner shaft of the telescopic shaft A13 is reversely rotated, the tail end of the external thread 53 is in threaded fit with the thread sleeve A45, so that the inner shaft of the telescopic shaft A13 is reset along the axial direction of the inner shaft, which is far away from the conveying cylinder 4, the sliding shaft 46 and the spiral sheet 48 are pulled by the inner shaft of the telescopic shaft A13 to be reset along the direction of the telescopic shaft A13, and the inner shaft of the telescopic shaft B32 is reset; in the period, the A snap ring 52, the B snap ring 57, the A ring 51 and the B ring 56 are synchronously reset along with the inner shaft of the A telescopic shaft 13, the A tension spring 55 is gradually stretched, and the B tension spring 60 is gradually restored to a natural state. When the head end of the external thread 53 is just disengaged from the A thread sleeve 45, the tail end of the spiral sheet 48 is positioned at the bottom of the conveying cylinder 4. The inverted flights 48 utilize the principle of screw lift to transport plastic from the bottom of the transfer cylinder 4 to the discharge opening 30, from where the plastic drops into the compounding conveyor mechanism of the extruder. During the plastic conveying process of the spiral piece 48, water carried on the plastic can flow back to the bottom of the conveying cylinder 4 from the leakage holes 49 of the spiral piece 48; as the plastic passes through the region of the electric heating jacket 5, the electric heating jacket 5 heats the region of the transport cylinder 4 to dry the plastic.

The screw rod 36 is reversely rotated after the reversely-rotated bevel gear B33 is subjected to a series of transmissions, and the D shaft 37 drives the piston 40 to move downwards through the threaded matching of the reversely-rotated screw rod 36 and the thread sleeve B9; as the plastic is about to be delivered to the discharge opening 30, the piston 40 moves downward into the barrel 12; as the plastic is gradually discharged from the discharge opening 30, the piston 40, which is moved further downwards, increases the pressure in the cylinder 12 and causes the auxiliary agent to flow from the B hose 43 via the pressure valve 41 into the compound conveying mechanism of the extruder. And mixing the plastic and the auxiliary agent by a mixing and conveying mechanism of the extruder. And after the plastic is discharged, adding waste plastic into the crushing mechanism again, and repeating the process of opening the electric control valve of the water inlet pipe and electrically driving to rotate forwards.

While the present invention has been described in conjunction with the above embodiments, the present invention is not limited to the above embodiments but is limited only by the appended claims, and those skilled in the art can easily make modifications and variations thereto without departing from the true spirit and scope of the present invention.
