Description

TECHNICAL FIELD

[0001] The utility model relates to a plate turnover machine technical field especially no scratch plate turnover machine. BACKGROUND

[0002] The frame of the plate turnover machine is the basic support structure of the whole device, which is usually welded with high-strength steel. This kind of steel has good strength and toughness, and can withstand various loads during the plate turnover process. The design shape of the frame is mostly cuboid or cube to ensure the stability of the structure. Its size is determined according to the maximum size of the plate to be turned over. There are various ways to drive the rotation of the rotating shaft, such as hydraulic drive and motor drive. Hydraulic drive converts hydraulic energy into mechanical energy of the rotating shaft through the connection of hydraulic cylinder and connecting rod mechanism. Motor drive drives the rotating shaft to rotate through the speed reduction and coupling transmission components of the motor. Hydraulic drive has larger torque output and can adapt to the turnover of heavier plates. Motor drive has higher control accuracy and speed adjustment range, and is suitable for occasions with high requirements for turnover accuracy and speed.

[0003] The plate turnover machine can control the turnover angle of the plate according to different production needs. Through the angle sensor installed on the rotating shaft or other key positions, the turnover angle of the plate is monitored in real time. When the preset turnover angle is reached, the control system will issue an instruction to stop the work of the turnover mechanism. However, the conventional plate turnover machine currently used, especially during the process of turning over the stainless steel plate by one hundred and eighty degrees, is prone to scratching the side of the stainless steel plate, including the longitudinal and transverse sides of the side. Therefore, the user is extremely annoyed, and at the same time, when the lifting arm of the traditional plate turnover machine is raised, the steel plate on the lifting arm will slide up and down on the pulley of the lifting arm to the root of the lifting arm after rotating a certain angle. At this time, the impact force generated will impact the wear-resistant plate at the root of the lifting arm, causing serious scratches and injuries. SUMMARY

[0004] In order to make up for the above shortcomings, the utility model provides a no scratch plate turnover machine, which aims to improve the conventional plate turnover machine currently used in the prior art, especially during the process of turning over the stainless steel plate by one hundred and eighty degrees, which is prone to scratching the side of the stainless steel plate, including the longitudinal and transverse sides of the side.
