[0031] This embodiment also discloses a method for accurately calibrating the position of the nozzle 2. The method is used to calibrate the position of the nozzle 2 on the feeding barrel 1. The calibration method includes the calibration device described above. The calibration method is performed in the following steps:

[0032] Step 1: Use the nozzle 2 in the correct position as the reference nozzle, and select any point on the reference nozzle outside the feeding cylinder 1 as the detection reference point;

[0033] Step 2: Obtain the reference position parameters of the detection reference point on the reference nozzle.
