Description

Technical Field

[0002] During the cutting process of a steam turbine rotor shaft by a numerical control lathe, a large amount of waste chips such as metal flakes or thin strips will be cut from the steam turbine rotor shaft. If these waste chips are not properly processed, they will not only cause environmental pollution, but also may block the cutting tool and affect the normal operation of the machine tool. Therefore, the treatment of waste chips is an important link in the numerical control lathe processing of a steam turbine rotor shaft. At present, the methods for waste chip treatment mainly include using waste chip treatment devices, manual cleaning, etc. The existing waste chip treatment devices generally set up waste chip collecting devices near the machine tool processing area, collect the waste chips from the cutting area, and discharge them outside the machine tool through a conveyor belt.

[0003] However, during the process of conveying and discharging waste chips through the conveyor belt, some waste chips will adhere to the conveyor belt, resulting in problems such as easy residue on the conveyor belt and incomplete dumping of waste chips when dumping waste chips; and generally, waste chips are collected by a trolley. When collecting the waste chips discharged by the trolley, the discharge port position of the conveyor belt is relatively high, and the impact force of the falling waste chips is relatively large, which easily causes the trolley to shift and affects the collection effect.
