The equipment is mainly composed of a frame, a squeezing cylinder, a heating and cooling device, a pre-granulating device, etc. It is widely used in the recycling and treatment of various waste plastics such as plastic films, woven bags, and beverage bottles; During the production of the current extrusion pre-pelletizer for plastic recycling, the material is easy to harden after being continuously squeezed by the extrusion screw in the squeezing barrel. Especially when the machine is shut down, if the material is not discharged in time, it is very easy to harden at the discharge hole and cause blockage, which requires regular maintenance and cleaning, which is time-consuming and labor-intensive.

[0003] Secondly, a large amount of water will remain in the waste plastic during the cleaning process, which will cause bubbles to appear in the melt, thus affecting the quality of granulation. Therefore, the waste must be dried before processing, but the dried material may still be affected by the water vapor in the environment, so there is a problem of how to efficiently preheat and dry the plastic at the feed point to prevent water vapor from entering the subsequent process.

[0004] Finally, the current finished plastic pellets have various sizes, such as 1-5mm, 3-8mm, etc., but the existing equipment cannot produce plastic pellets of multiple sizes at the same time.

Later, when it is necessary to stop the machine for cleaning, when the driving threaded rod 806 drives the limiting circular plate 807 to move, the limiting circular plate 807 will drive the high temperature resistant synthetic rubber flexible plate 809 to move to one side, thereby causing the high temperature resistant synthetic rubber flexible plate 809 to bend to the other side under force. When the high temperature resistant synthetic rubber flexible plate 809 is attached to the inner wall of the extrusion shell 2, the high temperature resistant synthetic rubber flexible plate 809 will push the melted material to move; Among them, the controller 10 is connected to the driving motor 9, the heating element 14, the heating rod 406, the electric control cylinder 720 and the electric control magnetic ring 803 through wires and the connection method is electrical connection, so that the controller 10 controls the driving motor 9, the heating element 14, the heating rod 406, the electric control cylinder 720 and the electric control magnetic ring 803 to power on and operate.

[0029] When the extrusion pre-cutting pelletizer for plastic recycling of the present scheme is working, a feed shell 401 is arranged on the top outer wall of the extrusion shell 2, and the plastic particles to be processed are placed into the inner cavity of the feed shell 401, and then the switch of the controller 10 is turned on, and the controller 10 controls the heating rod 406 to operate, so that the heating rod 406 preheats the plastic particles in the inner cavity of the feed shell 401, thereby drying the plastic particles in the inner cavity of the feed shell 401, and at the same time, since the heating rod 406 is provided with multiple groups and in a rectangular array structure, the multiple groups of heating rods 406 can better heat the plastic particles at different positions, and at the same time, the controller 10 controls the driving motor 9 to operate, so that the driving shaft of the driving motor 9 drives the gear box 11 to operate, and when the gear box 11 operates, the output end of the gear box 11 drives the driving rod 12 to rotate, and when the driving rod 12 rotates, the driving rod 12 drives the screw 13 to rotate; The driving rod 12 drives the driving gear 404 to operate, which causes the driving gear 404 to drive the transmission gear 403 to operate through meshing connection, and then the transmission gear 403 drives the rotating rod 402 to rotate. When the rotating rod 402 rotates, the rotating rod 402 drives the baffle 405 to rotate. Since the transmission gear 403 is respectively meshed and connected to the opposite outer walls of the driving gear 404, the baffles 405 on the outer walls of the two groups of rotating rods 402 rotate in opposite directions. When the baffles 405 are staggered and close to each other, the plastic material in the inner cavity of the feed shell 401 is retained for a longer time, the preheating effect is better, and the water vapor in the environment is prevented from entering the device. Then, when the baffles 405 are parallel to each other, the material in the inner cavity of the feed shell 401 enters the extrusion shell 2, thereby solving the problem of efficiently preheating and drying the plastic at the feed and preventing water vapor from entering the subsequent process. The material is spirally extruded by the screw 13, and the controller 10 controls the heating element 14 to heat and melt the material. When the melted material enters the cooling extrusion element 5, the cooling extrusion element 5 cools the melted material, and the cooled plastic part slides out through the discharge hole 6; One end of the rotating shaft 705 passes through the cooling extrusion piece 5 and extends to the inner cavity of the extrusion shell 2 and is connected to the screw 13. When the screw 13 is driven by the driving rod 12 to rotate, the screw 13 will drive the rotating shaft 705 to rotate, and then the rotating shaft 705 will drive the limiting turntable 707 to rotate. Since the limiting arc groove 708 is provided on the outer wall of the limiting turntable 707, when the limiting turntable 707 rotates, the limiting turntable 707 will apply a thrust to the limiting slide bar 709 through the limiting arc groove 708. At this time, since the limiting arc groove 708 is formed by the outer convex groove 7081 and the inner groove 7082. When the outer convex groove 7081 of the limiting arc groove 708 contacts the limiting slide bar 709, the limiting turntable 707 applies an outward thrust to the limiting slide bar 709 through the outer convex groove 7081. Conversely, when the inner groove 7082 of the limiting arc groove 708 contacts the limiting slide bar 709, the limiting turntable 707 applies an inward pulling force to the limiting slide bar 709 through the inner groove 7082, so that the limiting turntable 707 applies a reciprocating force to the limiting slide bar 709 through the limiting arc groove 708, thereby causing the limiting slide bar 709 to reciprocate back and forth. The limiting slide bar 709 applies a reciprocating thrust to the fixed sleeve 711 through the first connecting plate 710, and then the fixed sleeve 711 applies a reciprocating thrust to the pull rod 713 through the second connecting plate 712. When the pull rod 713 is displaced by force, the pull rod 713 applies a lateral reciprocating thrust to the connecting rod 723 through the positioning plate 714. When the connecting rod 723 is moved by force, the connecting rod 723 drives the sliding sleeve 718 to move through the fixed block 722, and then the sliding sleeve 718 moves laterally on the outer wall of the sliding lever 717. Then the sliding sleeve 718 drives the cutting blade 719 to pelletize the plastic. Since the cross partition 703 is located on the outer wall of the cooling extrusion 5, the cross partition 703 separates the cavity on one side of the cooling extrusion 5. Cutting blades 719 are arranged on both sides of the cross partition 703. When the limiting turntable 707 passes through the limiting arc groove 708, it applies force to the limiting slide bars 709 on both sides at the same time, so that the limiting slide bars 709 on both sides move back and forth at the same time. After transmission, the cutting blades 719 on both sides pelletize the plastic respectively. Under the action of the electric control cylinder 720 symmetrically arranged on the inner wall of the mounting bracket 702, when the size of the plastic particles needs to be adjusted, it is only necessary to turn on the switch of the controller 10 so that the controller 10 controls the electric control cylinder 720 to operate. When one end of the electric control cylinder 720 pushes the limit slider 721 to move, the limit slider 721 applies a thrust to the sliding sleeve 718. Since the sliding sleeve 718 is slidably connected to the outer wall of the sliding lever 717, the limit slider 721 applies a thrust to the sliding lever 717 through the sliding sleeve 718, so that the sliding lever 717 moves on the inner wall of the sliding groove 716. At the same time, when the sliding When the movable lever 717 moves on the inner wall of the slide groove 716, the sliding lever 717 drives the cutting blade 719 to move through the sliding sleeve 718, so that the distance between the cutting blade 719 and the discharge hole 6 can be flexibly adjusted, so that the size of the cut plastic particles meets the production requirements, and the two groups of cutting blades 719 in the inner cavity of the cutting component 7 can be adjusted separately, so that the device can cut and produce plastic particles of different sizes at the same time, making the production efficiency more efficient, and the production efficiency of the cutting component 7 is more efficient, thereby solving the problem that the existing equipment cannot produce plastic particles of various specifications at the same time, thereby improving the work efficiency; An electric controlled magnetic ring 803 is arranged at one end of the electrical slip ring 802. The electric controlled magnetic ring 803 is rotatably connected to the outer wall of the rotating shaft 705. When the device is shut down, it is only necessary to turn on the switch of the controller 10 so that the controller 10 controls the electric controlled magnetic ring 803 to operate. When the electric controlled magnetic ring 803 is energized to generate magnetism, the connection mode between the electric controlled magnetic ring 803 and the rotating shaft 705 is a magnetic connection, so that the electric controlled magnetic ring 803 is magnetically adsorbed on the outer wall of the rotating shaft 705 for fixation, thereby making the electric controlled magnetic ring 803 rotate synchronously with the rotating shaft 705. When the electric controlled magnetic ring 803 rotates, the electric controlled magnetic ring 803 drives the active gear 804 to rotate, and then the active gear 804 drives the driven gear 805 to rotate, and then the driven gear 805 drives the driving threaded rod 806 to rotate. When the driving threaded rod 806 rotates, the driving threaded rod 806 drives the limiting circular plate through the threaded connection. 807 moves laterally, and at the same time, the limiting circular plate 807 slides laterally on the outer wall of the rotating shaft 705, so that the limiting circular plate 807 drives the high-temperature resistant synthetic rubber flexible plate 809 to move, and the high-temperature resistant synthetic rubber flexible plate 809 is attached to the inner wall of the extrusion shell 2, so that the high-temperature resistant synthetic rubber flexible plate 809 pushes the material in the inner cavity of the extrusion shell 2 to one side, and at the same time, the outer wall of the limiting circular plate 807 and the position corresponding to the discharge hole 6 are sequentially provided with the push rod 808. When the limiting circular plate 807 is attached to the inner wall of the cooling extrusion part 5, the push rod 808 will also be inserted into the discharge hole 6, so that the material in the inner cavity of the extrusion shell 2 is discharged as clean as possible to prevent subsequent material solidification and blockage, thereby solving the problem that if the material is not discharged in time during the production of the extrusion pre-cutting machine for plastic recycling, it is very easy to harden at the discharge hole and cause blockage, so that there is no need for regular maintenance and cleaning, thereby achieving the effect of saving time and effort.
