[0002] This device is an automatic lifting device for a circular cylinder based on a mechanical structure. The device is mainly used in the fields of industry, construction, etc. The circular cylinder is tilted, with feeding at one end and discharging at one side. At the same time, a rotating device can be set on the outside of the circular cylinder to rotate the circular cylinder or a heating device can be set to dry the outside of the circular cylinder. The tilt angle of the circular cylinder can be controlled by the lifting equipment below to control the feeding and discharging speed. It has the characteristics of stable lifting, high precision, safety and reliability. It greatly reduces the manual adjustment operation time and greatly improves work efficiency. In addition, since the automatic lifting operation is simple, the user does not need to spend too much energy on adjusting the height; because the mass of the bearing circular cylinder is large, the screw is adjusted manually, which is prone to slipping, sedimentation and other phenomena.
