Description

Technical Field

[0001] The utility model relates to the technical field of marking machines, in particular to a novel turning mechanism for a marking machine. Background Art

[0002] Marking machines are mainly divided into three types: pneumatic, laser, and electro-erosion. Pneumatic: computer controlled, the print needle performs high-frequency impact motion under the action of compressed air, thereby printing a mark with a certain depth on the workpiece. Marking characteristics: large depth; Laser marking machine uses a laser beam to mark the surface of various materials permanently. The effect of marking is to expose the deep material through the evaporation of the surface material, so as to carve out exquisite patterns, trademarks and texts; electro-corrosion mainly prints fixed trademarks, just like stamping, but it is inconvenient to change the printing content. When the pneumatic and laser marking machines are marking on both sides of the workpiece, the workpiece needs to be turned over after marking on one side, and the other side needs to be marked. At present, people usually turn over the workpiece manually, and the manual turning speed is slow. In batch marking, the manual operation speed will be affected by the fatigue level of the personnel, resulting in low marking efficiency. In addition, when the pneumatic and laser marking machines are turned over manually, people have to reach under the marking head to operate. Once the marking machine malfunctions or manual misoperation occurs, it is easy to cause people to be injured, and there are certain safety hazards. Utility Model Content
