[0002] The pelletizer is used for pelletizing long strip-shaped polyester resin in a water channel. The pelletizer consists of a workbench, a pelletizing chamber, a cutting blade, a motor, a pellet discharging bin, a feeding port, and rollers. When cutting the long strip-shaped polyester resin flowing through the cutting channel, the polyester resin is limited by the rollers in the feeding port. The motor is started to drive the cutting blade to rotate, so as to pelletize the polyester resin. The granular polyester resin exits through the pellet discharging bin under the workbench.

At the same time, the air outlet holes blow out the granular resin in the arc-shaped grooves. A sealing ring is used to seal between the rotating shaft and the fixed rod, solving the problem that since the long strip-shaped polyester resin is in water, the granular polyester resin cut by the cutting blade may be thrown onto the inner wall of the granule outlet bin as the cutting blade rotates. Because there is moisture on the surface of the granular polyester resin, it may adhere to the inner wall of the granule outlet bin and cannot normally discharge granules, thereby affecting the granulation efficiency.

[0034] Working principle:

[0035] When cutting the strip-shaped polyester resin flowing from the cutting water channel, the polyester resin is limited by the roller 7 in the feeding port 9. The first motor 6 is started to drive the cutting knife 5 in the granulation chamber 4 to rotate, so as to granulate the polyester resin. The granular polyester resin exits through the granulation bin 8 under the workbench 1. When scraping off the granular polyester resin adhering to the inner wall of the granulation bin 8, the driving mechanism 23 is used to make the scraper 21 rotate, so that the scraper 21 rotates on the inner wall of the granulation bin 8 to scrape off the granular polyester resin adhering to the inner wall of the granulation bin 8. Connect the air pump to the air inlet pipe 232, so that air enters the air channel 231 and the air inlet cavity 234 in the fixed rod 233, making the turbine 236 rotate. The air enters the air delivery cavity 237 through the air delivery holes 238, then reaches the cavity arc rod 239, and finally exits through the air outlet holes 24 in the arc groove 22 on the scraper 21, so as to make the rotating shaft 235 rotate. At the same time, the air in the air outlet holes 24 blows the granular resin in the arc groove 22. A sealing ring is used to seal between the rotating shaft 235 and the fixed rod 233. The air in the air outlet holes 24 pushes the push plate 25 to push out the granular resin in the arc groove 22. By setting the spring 26, the push plate 25 is reset. When grinding the cutting knife 5, the grinding block 31 is moved on the surface of the cutting knife 5 through the moving mechanism. At the same time, the grinding liquid in the liquid cavity 32 flows out through the liquid outlet hole 33, so as to better grind the cutting knife 5. When the grinding block 31 moves, the circular block 34 rotates, and then the grinding liquid is evenly applied to the cutting knife 5. The second motor 310 on the rectangular block 36 is started to drive the screw rod 37 to rotate, so that the grinding block 31 moves on the limiting rod 38, pushing the rectangular block 36 to slide on the inner wall of the slideway 39. The liquid cavity 32 is filled with liquid through the liquid receiving pipe 35.
