[0014] Compared with the prior art, this utility model provides a discharge mechanism for a PET modified material granulator, which has the following beneficial effects:

[0015] 1. Through the configuration of the cover plate, blower, corrugated pipe, dust hood, feed inlet, and dust collection box, the cover plate effectively blocks the dust generated by the modified PET material during the screening process. Combined with the system design of the blower and dust hood, the dust is smoothly fed into the dust collection box through the flexibly connected corrugated pipe, achieving efficient dust collection. The unique separate feed inlet design ensures complete isolation between the feed hopper and the vibrating components, maintaining the stability of the feed and avoiding vibration interference. The flexible characteristics of the corrugated pipe allow it to vibrate freely with the cover plate without affecting the dust collection effect, ensuring continuous and stable operation of the entire dust removal process.

[0016] 2. With the setup of a water tank, inlet, drain faucet, high-pressure water pump, water pipes, and atomizing nozzles, the water tank system allows for convenient water filling via the inlet. The high-pressure water pump delivers water to the dust collection box, where it is atomized into a fine mist, effectively suppressing the spread of dust inside the box. The drain faucet at the bottom facilitates the periodic removal of accumulated dust-water mixtures, keeping the dust collection box clean. This water circulation dust suppression system is not only easy to operate but also significantly reduces the risk of secondary dust generation, ensuring a clean and safe working environment.

[0025] In this embodiment, the discharge mechanism of the PET modified material granulator is a key component responsible for conveying the processed plastic granules from the equipment to the collection system during the granulation process. Its core function is to ensure that the granules are discharged efficiently and uniformly after the molten PET modified material is extruded and cut into shape, and to complete cooling, screening and collection. The discharge mechanism is mainly used to screen the PET modified material produced by the granulator. The PET modified material enters the screen plate 4 through the feed hopper 16. Then, the vibration motor at the bottom of the bottom frame 1 is turned on, which can make the bottom frame 1 and the internal screen plate 4 vibrate. At the same time, the vibration effect of the four corner springs 7 can be enhanced. The size of the raw material can be screened by the vibration of the multi-layer screen plate 4. Then, the screened PET modified material can be discharged through the discharge port 5.

[0026] like Figure 1 and Figure 3 As shown, the cover plate 2 is fixedly installed to the base frame 1 with screws. The dust hood 3 is integrally formed with the cover plate 2. The corrugated pipe 13 is inserted into the dust hood 3. Multiple corrugated pipes 13 are finally connected to one corrugated pipe 13. The corrugated pipe 13 is sleeved with the blower 14. The blower 14 is fixedly installed to the mounting plate 15 with screws. The mounting plate 15 is welded to the feed hopper 16. The exhaust port of the blower 14 is connected to the dust collection box 10 through the corrugated pipe 13. The dust collection box 10 can collect dust.

The dust collection box 10 and the water tank 11 are formed by a partition inside the box.

[0027] Preferably, through the arrangement of cover plate 2, blower 14, corrugated pipe 13, dust hood 3, feed inlet 17 and dust collection box 10, when the sieve plate 4 screens the PET modified material, the generated dust can be blocked by cover plate 2. Turning on blower 14 can allow the dust to be discharged into dust collection box 10 through dust hood 3 and corrugated pipe 13, thus completing the collection of dust. The feed inlet 17 and feed hopper 16 adopt a separate design, which can ensure that feed hopper 16 will not vibrate with cover plate 2 and bottom frame 1, ensuring the stability of feed hopper 16. The flexible structure of corrugated pipe 13 can ensure that corrugated pipe 13 will not be affected when vibrating with cover plate 2, ensuring the stability of dust collection process.

A water pipe 18 is provided between the high-pressure water pump 19, the water tank 11, and the dust collection box 10. One end of the water pipe 18 is equipped with an atomizing nozzle 20, which is located at the top inside the dust collection box 10. The cover plate 2 is equipped with a feed inlet 17, and the feed hopper 16 is positioned below the feed inlet 17, allowing the feed hopper 16 to feed material onto the screen plate 4 through the feed inlet 17.

Opening the drain faucet 9 at the bottom can discharge the mixture of dust and water inside the dust collection box 10, thus completing the cleaning of the dust collection box 10.
