Description

Technical Field

[0001] The utility model relates to the technical field of glass processing equipment, in particular to a pressing device of an edge grinding machine. Background Art

[0002] A four-sided edge grinding machine is a device specially used for grinding the four sides of glass. It has the characteristics of high precision, high efficiency and high stability, and can greatly improve the processing quality and efficiency of glass. When operating the four-sided edge grinding machine, it is necessary to first place the glass on the workbench of the machine, and then control the motion trajectory and grinding amount of the grinding head through a computer control system to achieve the desired grinding effect. CN 105881141 B discloses a four-sided bottom edge grinding machine, and specifically discloses a clamping component group. When it works, the clamping component group cooperates with the conveying roller to realize the clamping and conveying of the glass. During use, each clamping wheel of the clamping component group contacts the surface of the glass. If there is a deviation during assembly, or the equipment vibrates during use, the contact force between each clamping wheel and the glass will be uneven, and the clamping wheel is prone to abnormal wear. In severe cases, the glass will be damaged due to uneven force; therefore, the installation and debugging requirements of the clamping component group are very high, and the installation and maintenance are very time-consuming and labor-consuming, and regular inspection and verification are required, and the maintenance cost is also high.
