[0021] Embodiment:

[0022] Please refer to Figures 1-4 The embodiment shows a granulator for producing high-proportion glass fiber reinforced polyamide material, which comprises a granulator main body, a machine head and a granule collecting device, and the granulator main body is provided with a scraper 8 and a motor 1.

[0023] The motor 1 is arranged on a sliding rail 3 and is provided with a pulley 2, and the connection and disconnection of the cover and the die hole plate can be realized through translation.

[0024] The cover 8 and the die 12 are connected, and the center shaft of the scraper 8 is located on the bearing of the center shaft of the die.

[0025] The cover 8 is arranged inside the cover 10, and the center shaft of the scraper 8 is connected with the bearing 16 when the cover 10 is connected with the die hole plate 12.

[0026] The scraper 8 is circular, and the scraper can cut the flowing material into particles when rotating.

[0027] When the cover 10 is connected with the die plate 12, the doctor blade 8 scrapes the molten resin flowing outside the circle hole 15.

[0028] The universal joint 6 is arranged on the bottom of the pelletizing device main body, and the device can be conveniently disassembled.

[0029] The base 4 of the pelletizing device is arranged below the pelletizing device main body, and a height adjusting screw module is arranged on the base 4, and the height adjusting screw module has a height adjusting nut 5, so that the height of the device can be adjusted.
