Description

Technical Field

[0002] The engraving machine is a very common device used in the advertising decoration industry. Many people also call it a plotter, a cutting machine, etc. Its working method is that it is connected to a computer, receives the computer's instructions, and is controlled and driven by the computer. When using a plotter, it often requires multiple paper pressing devices to press the material tightly to avoid wrinkles. Many paper pressing wheel devices used in the engraving machines on the market are single-control. When the machine is working, the pressing wheel devices need to be pressed down one by one for the machine to work normally, which wastes time in operation. If it is found that the paper pressing force of individual pressing wheel devices is different, it will also cause the paper to arch, thereby affecting the progress of engraving.
