The purpose and effect of the automatic quantitative liquid injection instrument of the present utility model are achieved by the following specific technical means:

An automatic quantitative liquid injection instrument, including a liquid injection instrument main body; a switch knob and a display screen are provided on the liquid injection instrument main body; a stepping motor A is arranged inside the liquid injection instrument main body, and the stepping motor A is fixed on A feeding turntable is connected, and a pan-clamping moving iron piece driven by an eccentric bearing is fixedly connected to the feeding turntable; a stepping motor B is arranged inside the main body of the liquid injection instrument, and the stepping A discharge turntable is fixedly connected to the rotating shaft of the motor B; a stepper motor C and an associated synchronous pulley are arranged inside the main body of the liquid injection instrument, and the stepper motor C and the associated synchronous pulley are sleeved with a A transmission belt; the main body of the liquid injection instrument is provided with a liquid storage tank and a micro liquid injection pump, and the liquid storage tank and the micro liquid injection pump are connected through a pipeline, and the micro liquid injection pump is connected with the liquid injection head through a pipeline connected.

Further, two handles are symmetrically arranged on the left end face and the right end face of the main body of the liquid injection instrument.

Further, the micro injection pump is provided with an angle adjustment structure of the injection pump on the side of the pump head.

Further, the induction of the position of the crucible receiving medicine is through-beam optical fiber induction.

Compared with the prior art, the utility model has the following beneficial effects:

Through the cooperation and setting of stepper motor A, feeding turntable, pot-clamping moving iron sheet, stepper motor B, discharging turntable, stepper motor C, transmission belt, liquid storage tank and micro liquid injection pump, the device can be used when working. , Driven by the feeding turntable, the crucibles line up and enter the conveyor belt, the crucible stops under the liquid injection needle, and the needle automatically injects drops into the crucible. After the crucible receives medicine, it continues to move forward. Driven by the material turntable, when the potion sinks into the steel wool in the crucible, and the discharge turntable flows into the crucible in an appropriate amount, the equipment is suspended and the completed crucible is taken away to continue the operation, so it can improve the consistency of the pot injection and collection, and improve the Productivity.

Due to the setting of the moving iron piece for the tongs pan finishing, because the eccentric bearing is arranged in the moving iron piece of the tongs pan, the eccentric bearing drives the movement of the adjusting iron piece when it rotates, so the orderly movement of the tongs can be ensured.

Because the injection pump angle adjustment structure is provided on the pump head side of the micro injection pump, and the working mode is: the stepper motor with deceleration drives the micro gear, the micro gear drives the angle gear of the injection pump, the angle accuracy is 0.01°, and the injection volume per injection The size is controlled by the angle of the liquid injection pump. The smaller the angle, the smaller the liquid output. The liquid injection range of this equipment is 0.005-3ml.

Because the induction of the crucible receiving position is through-beam optical fiber induction, it is stable and reliable.
