At the same time, the long-term operation of the driving device to drive the syringe to move will increase the equipment cost and increase energy consumption; secondly, when in use, the existing automatic filling equipment for injection uses an air pump to pressurize the injection raw material tank to realize injection filling, and when this method adjusts the injection filling speed, it is necessary to adjust the power of the air pump, thereby increasing the energy consumption of the air pump and causing waste; finally, when in use, the existing automatic filling equipment for injection fills a container of a certain size through a filling component, and this method cannot adjust the position of the syringe and the container conveying track spacing according to the volume of the container when filling the injection, affecting the scope of application of the filling equipment; therefore, it is necessary to improve the existing technology to solve the above technical problems.
