Liquid glue output control system and method of double-plunger pump

The invention provides a liquid glue output control system and method for double plunger pumps, a main control module generates a material calling instruction when an injection molding machine calls materials, a servo module enters a glue output execution mode when receiving the material calling instruction, the plunger pumps connected with the servo module are driven to move, and liquid glue in a corresponding container is injected into a mixing module; the main control module monitors the operation states of the two plunger pumps in a glue outlet execution mode, and when one plunger pump has a preset state variable, a state change instruction is generated and sent to the servo module connected with the other plunger pump; and the servo module changes the running state of the connected plunger pump when receiving the state change instruction. And the other plunger pump is synchronously controlled according to the running state, so that the stability of the glue outlet proportion of the two types of liquid gl
