TECHNICAL FIELD
[0001] The utility model relates to the technical field of engraving machine equipment, concretely to a blocking device of engraving machine. BACKGROUND
[0002] The engraving machine is a kind of mechanical equipment for cutting, engraving and hollowing operation on various materials (such as wood, plastic, metal, stone, etc.). It is usually driven by a moving frame cutter or laser head, and precise cutting and engraving are realized through a computer numerical control system. According to the application requirements, the engraving machine can be divided into mechanical engraving machine, laser engraving machine and water jet engraving machine, etc.
[0003] When the mechanical engraving machine is working, it will produce flying debris, which will be scattered in the air and inhaled by the operator, causing harm to health. At the same time, if the debris falls into the mechanical parts of the engraving machine, it may cause equipment wear, jam or failure. Therefore, when engraving boards such as wood, plastic, metal and stone, in order to block the flying debris, the staff often binds a soft shell (usually a paper shell or a plastic shell) for blocking the flying debris around the mounting head on the engraving machine, so that the cutting tool on the mounting head is located inside the soft shell. Although this method can block the debris, the soft shell for blocking the flying debris cannot always be in close contact with the upper surface of the workpiece during engraving, and the blocking effect is poor. At the same time, the soft shell fixed on the mounting head will hinder the replacement of the new cutting tool. When replacing the cutting tool, the soft shell fixed on the mounting head needs to be removed, and then installed back after replacement. The operation is complicated. Therefore, we propose a blocking device for engraving machine. CONTENT OF UTILITY MODEL
