Description

Technical Field

[0002] Marking machine is a kind of equipment used to print text, graphics, barcodes and other marks on the surface of different materials. It is widely used in various industrial manufacturing, medical and health, food and beverage, cosmetics and other industries. It is mainly divided into three types: pneumatic, laser and electro-corrosion. Pneumatic is controlled by computer. The print needle performs high-frequency impact movement under the action of compressed air, thereby printing a mark with a certain depth on the workpiece. The laser marking machine uses a laser beam to mark the surface of various materials permanently. Electro-corrosion mainly prints fixed trademarks, just like stamping, but it is inconvenient to change the printed content.

[0003] When using some traditional marking machines, the workpiece is placed under the marking head and the body structure is used to mark the workpiece surface. However, the surface of some workpieces is not horizontal, but inclined. When marking such inclined surfaces, they need to be adjusted to a horizontal state to ensure the accuracy of marking. Some traditional marking machines lack a convenient adjustment structure, and manual adjustment is required during marking, which causes certain inconveniences in marking. Utility Model Content
