[0056] The thermos cup 24 is placed in the mold shell 23 manually or by a robot. A sensing device is provided on the frame 12. The sensing device senses the position of the thermos cup 24 and sends a signal to the host computer. After receiving the signal, the host computer controls the second motor 41 to work. The positioning of the sensing device is the prior art and is not repeated here. The host computer controls the second motor 41 to move the grinding head 55 to a suitable position. The host computer controls the third motor 51 to make the grinding head 55 abut against the cup mouth of the thermos cup 24 at a suitable angle. The host computer controls the first motor 21 to start, the thermos cup 24 rotates, and the sand belt of the grinding head 55 grinds the cup mouth of the thermos cup 24. The host computer controls the blower to start, and the dust suction pipe 75 discharges the dust generated by polishing. When the first motor 21 is started, the upper computer controls the fourth motor 31 to start. The fourth motor 31 starts the sanding belt to transmit. The second sanding belt disc 34 and the first sanding belt disc 33 cooperate to keep the sanding belt at the grinding head 55 in a sharp and unused state. The used sanding belt is wound around the first sanding belt disc 33, and the unused sanding belt is wound around the second sanding belt disc 34.

[0057] In the above scheme, by setting up multiple workstations and multiple components that can work simultaneously, multiple thermos cups can be processed at the same time, thereby improving production efficiency; the position of the grinding head can be accurately controlled so that the grinding head and the mouth of the thermos cup can be precisely fitted, thereby improving polishing efficiency; a dust suction component is provided to process the dust generated during the polishing process, thereby reducing pollution and ensuring the health of the staff; a sanding belt replacement component is provided to ensure that the sanding belt at the grinding head is always in a sharp state, thereby improving polishing efficiency.
