Description

Technical Field

[0001] This utility model relates to the technical field of stone processing equipment, specifically to an edge grinding machine. Background Technology

[0002] In the field of tile or stone processing equipment, edge grinding machines are widely used as grinding devices for the straight edges of tiles or stones. Edge grinding machines typically use conveyor belts to transport the stone. During processing, to prevent the stone from shifting and to ensure processing accuracy, a certain pressure is usually applied to the stone. Combined with the weight of the stone itself, the conveyor belt will sag and come into contact with the machine frame. During the transport process, the conveyor belt will continuously rub against the machine frame, causing wear and tear on the frame and thus affecting its service life.

[0003] In view of this, the applicant in this case conducted in-depth research on the above issues, which led to the occurrence of this case. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing an edge grinding machine that can effectively avoid wear caused by direct contact and friction between the edge grinding machine base and the conveyor belt, thereby extending the service life of the edge grinding machine base.

[0005] The solution adopted by this utility model to solve the technical problem is: an edge grinding machine, including a base, a conveying mechanism for conveying the plate, and an edge grinding mechanism for grinding the plate. The conveying mechanism includes a conveyor belt, which is reciprocally mounted on the base. A conveying section is formed on the conveyor belt above the base. A grinding plate is provided on the base below the conveying section for frictional contact with the conveyor belt.
