Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment manufacturing, in particular to a double-beam multiple printing unit moving mechanism. Background Art

[0002] At present, the working position adjustment of most printing units is generally manual or semi-automatic, that is, the unit position is moved individually through a manual mechanical knob or a single electric switch button. This operation is cumbersome and the position adjustment is not accurate; when the moving distance is long, it takes a long time. The design of the patent of the present invention can realize the synchronous one-button precise positioning of all units, as well as the synchronous movement of the unit and the beam. When installing a printing device on the customer's original equipment, due to the small space, the staff cannot perform maintenance and repair work at the working position of the printing unit, so the printing unit needs to be moved out for maintenance and repair work, which requires the printing unit to move on a longer beam with a larger stroke; the movement of the printing unit is designed to be electric and is very convenient to operate compared to the manual movement of the printing unit, which solves the problem that the staff cannot move the printing unit in a small space.

[0003] The position of the printing unit during operation requires higher precision. Therefore, while ensuring that the motor has sufficient torque to drive the printing unit to move with high positioning accuracy, the motor that drives the printing unit to move does not run that fast. In this case, if the entire automatic crossbeam has a separate stroke and a long travel, it will take a relatively long time for multiple printing units to move to the maintenance position. The motor may also lose step during a long stroke, resulting in the inability to accurately position the printing unit.

[0004] Therefore, how to save the time of maintaining the printing unit during the production process and improve the production efficiency of printing has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0050] The utility model has the function of moving the printing unit 1 at high speed and over long distances. Each printing unit 1 can be automatically positioned and moved relative to the fixed screw 9 on the printing beam 14 through the corresponding printing unit moving motor 8. The printing beam 14 can also be moved as a whole on the base beam 18 through the main motor 23 and the mechanical transmission chain realized by the synchronous belt mechanism.

[0051] The utility model can greatly reduce the time of the entire maintenance process, and ensure that the printing beam 14 can be accurately moved to the working position of the printing unit while achieving high-speed movement of the printing beam on the base beam.
