Problems solved by technology

There are two main reasons: on the one hand, the problem is inevitable due to the control structure itself; on the other hand, the use of PLC as a control solution cannot solve this problem due to its relatively low processing speed.
Therefore, although the automatic packaging machine with double inverter structure is low in cost, simple in structure and low in noise, it is not widely used in the market.

Description

technical field [0001] The invention belongs to the technical field of non-electric power-electric power signal conversion, and more specifically relates to the design of a rotating speed-analog voltage conversion module controlled by a single-chip microcomputer in real time. Background technique [0002] In the existing automatic pillow packing machine with dual frequency converter structure, the synchronization between the master and slave motors is often destroyed after the material is cut during the production process. There are two main reasons: on the one hand, the problem is inevitable due to the control structure itself; on the other hand, the use of PLC as a control solution cannot solve this problem due to its relatively low processing speed. Therefore, although the automatic packaging machine with double inverter structure is low in cost, simple in structure and low in noise, it is not widely used in the market. The high-end automatic pi...
