The multi-color pad printer adopts a pneumatic rotary table as the main structure of the original multi-color pad printer. However, this type of pad printer has obvious shortcomings, such as low overprinting accuracy and insufficient running smoothness. This is the main feature of the pneumatic structure. , As more and more users have high requirements for overprinting accuracy, in recent years, multi-color pad printers have begun to use worktables in the form of indexing disc rotating structure. The index plate can be set with multiple positions and multiple angles, controlled by a motor, and the repeatability is relatively high. The overprint accuracy of the pad printer of the indexing table depends on the repeatability of the indexing table rotation and the tolerances formed by the production of the fixture. Therefore, the machining accuracy of the machine is relatively high, and it can only be manufactured by a mechanical factory with a higher level.
