The connecting plate, vertical plate, and fixed frame provide support for the rotating rod and transmission wheel. The rotating assembly drives a rotating drum to rotate, which in turn drives a hot air blower in a circular motion, facilitating uniform drying of the plastic pellets. Therefore, this plastic pelletizer with drying function facilitates uniform drying of the plastic pellets, ensuring more even and thorough drying, minimizing impact on the quality of the finished product, and demonstrating strong practicality.

[0003] According to its publicly available technical solutions, in the existing technology, after the plastic is output and formed by the discharge machine, the strip plastic is placed in cooling water for cooling. After cooling, the plastic is dehydrated and dried. This device requires multiple processing steps, which takes a long time and the equipment occupies a large area. Utility Model Content

This eliminates the dehydration and drying steps in traditional methods. Furthermore, a motor drives the annular blade and the circular pusher plate to rotate synchronously. The annular blade cuts along the annular hole to ensure consistent pellet length. The circular pusher plate inserts into the gaps between the cut pellets and pushes them out, avoiding the risk of the cut pellets clogging the long tube.

[0018] In this embodiment, the cutting assembly 2 includes a long tube 8, a rotating rod 21, a first square plate 12, and a fixed plate 14. A tapered tube 4 is connected to one end of the long tube 8, and the other end of the tapered tube 4 is connected to the side of the material box 1. An annular hole 15 is formed on the surface of the long tube 8, and an annular blade 17 is inserted inside the annular hole 15. A circular hole 16 is formed at the end of the long tube 8, with notches at both the top and bottom. The rotating rod 21 is inserted into the circular hole 16. An end baffle 26 is provided at the end of the annular blade 17. The top surface of the annular blade 17 is welded to the bottom surface of the rotating rod 21. The top surface of the rotating rod 21 is welded... A circular push plate 7 is attached, and a rotating shaft 10 is welded to the end of the rotating rod 21. The other end of the rotating shaft 10 is connected to a motor 13, which is mounted on the surface of the fixed plate 14. A groove 22 is provided on the surface of the first square plate 12, and a protrusion is connected to the bottom surface of the fixed plate 14. The protrusion is embedded in the groove 22. After the plastic inside the long tube 8 has cooled down, the motor 13 is turned on, and the motor 13 drives the rotating shaft 10 to rotate, which in turn drives the annular blade 17 and the circular push plate 7 to rotate, thus completing the cutting of the plastic. The fixed plate 14 is pushed, which in turn drives the circular push plate 7 and the annular blade 17, thus pushing out the cut plastic.

[0019] In this embodiment, the detachment mechanism 3 includes a long plate 11, a vertical plate 19, and a second square plate 18. The two ends of the second square plate 18 are respectively welded to the side of the water storage box 6 and the side of the first square plate 12. A first strip hole 9 is opened on the surface of the second square plate 18. The vertical plate 19 is inserted into the first strip hole 9. A second strip hole 25 is opened on the side of the second square plate 18. The long plate 11 is inserted into the second strip hole 25. The bottom surface of the vertical plate 19 is welded to the surface of the long plate 11. A square push plate 20 is welded to the top surface of the vertical plate 19. A brush is installed on the side of the square push plate 20. After the cut plastic is pushed out of the long tube 8, the handle on the top surface of the long plate 11 is pushed, which moves the square push plate 20 to move, thereby pushing away the plastic particles adhering to the surface of the circular push plate 7. At the same time, the brush on the side of the square push plate 20 cleans the surface of the circular push plate 7.

[0020] Working principle: Molten plastic enters the material box 1 through the feed pipe. The electric push rod 5 is activated, causing the push plate to move. This movement pushes the plastic from the material box 1 into the conical tube 4, and then into the long tube 8. The plastic inside the long tube 8 is prevented from flowing out by the end baffle 26. When the long tube 8 is full, the nozzle of the water storage box 6 is activated. The nozzle draws water from the water storage box 6 and sprays it onto the surface of the long tube 8, cooling it. This cooling process avoids direct water spray onto the plastic, eliminating the need for water cooling in traditional methods. After the plastic is glued, it undergoes a dehydration process. The water consumed by the cooling tube 8 is filtered through a filter and then returned to the water storage box 6. Once the plastic inside the tube 8 has cooled down, the motor 13 is turned on. The motor 13 drives the rotating shaft 10 to rotate, which in turn drives the rotating rod 21 to rotate. The rotating rod 21 then drives the annular blade 17, the circular push plate 7, and the end baffle 26 to rotate simultaneously. As the annular blade 17 rotates along the annular hole 15 of the tube 8, it cuts the plastic, creating gaps between the plastic particles. As the circular push plate 7 rotates, it inserts into the annular hole 15 and the gaps between the plastic particles. When the rotating shaft 10 rotates half a turn, it stops rotating. At this time, the circular push plate 7 is completely inside the long tube 8, pushing the fixed plate 14 to move along the slide groove 22. During the movement of the fixed plate 14, the motor 13, the rotating shaft 10, and the rotating rod 21 move synchronously. The movement of the rotating rod 21 causes the annular blade 17, the circular push plate 7, and the end baffle 26 to move along the notch at the top and bottom of the circular hole 16 in the long tube 8. The movement of the circular push plate 7 pushes the plastic inside the long tube 8 to the top of the second square plate 18. At this time, the handle on the top surface of the long plate 11 is pushed, causing the long plate 11 to move along the second strip hole 25. The movement of the long plate 11 carries... The vertical plate 19 and the square push plate 20 are displaced. During the displacement of the square push plate 20, the plastic particles stuck to the surface of the circular push plate 7 are peeled off. At the same time, the brush on the side of the square push plate 20 cleans the surface of the circular push plate 7. After peeling is completed, the handle of the long plate 11 is pulled to reset the long plate 11. The reset of the long plate 11 is linked to the synchronous reset of the vertical plate 19 and the square push plate 20. After collecting the plastic particles on the surface of the second square plate 18, the fixed plate 14 is pushed to reset. The reset of the fixed plate 14 is linked to the synchronous reset of the ring blade 17 and the circular push plate 7. The motor 13 is turned on, and the rotating shaft 10 is rotated half a turn and then turned off. The above process is repeated.
