AI Technical Summary
The lifting mechanism of traditional quartz grinding mills suffers from poor stability, low precision, and short lifespan in a waterless environment. In particular, during long-term operation, it is prone to wear of the lead screw and unstable lifting, as well as uneven heat dissipation of the main shaft.
The lifting bracket design employs a servo motor-driven ball screw and linear guide rail, combined with a water cooling system to dissipate heat from the spindle box. The weight of the lifting bracket is balanced by counterweights to reduce the load on the servo motor, ensuring smooth movement and spindle stability.
The lifting mechanism of the quartz grinding mill has been improved in terms of smoothness and stability, extending the service life of the equipment. The water cooling system ensures the long-term operational stability of the spindle.

[0002] The anhydrous quartz weight making machine is a mechanical device for lifting and rotating a quartz weight base column in a quartz glass deposition dissolving process, and the traditional quartz weight making machine usually adopts a hydraulic or pneumatic driving system, which can realize basic lifting and rotating functions, but has certain limitations in precision, stability and automation degree. In particular, in the anhydrous environment, how to ensure the efficient operation and long-term stability of the equipment becomes the focus of technical research. In the design of the lifting mechanism of the existing quartz weight making machine, a single ball screw driving mode is usually adopted, which can realize basic lifting function, but in the long-term operation process, the ball screw is prone to wear and tear, and the lifting is unstable, which affects the precision and service life of the equipment.
