High-viscosity liquid precise subpackaging device

Abstract

The invention relates to the field of a biological and chemical machine, and particularly discloses a high-viscosity liquid precise subpackaging device which comprises an electronic control system, an electrical system, a mechanical transmission system and a piston pump, wherein the electronic control system comprises a programmable logic controller (PLC) and a touch control screen; the electrical system comprises a piston servo motor and a rotary valve servo motor; the mechanical transmission system comprises a rolling shaft screw rod, a screw rod sliding block and a concentric shaft; the piston pump is provided with a liquid outlet pipe and a liquid inlet pipe; and a pipe orifice of the liquid outlet pipe is provided with a liquid outlet needle. The high-viscosity liquid precise subpackaging device can be automatically controlled to run by the PLC, can manually change various parameters, and is simple and convenient in operation and high in degree of mechanization. The servo motors are accurate in location and high in accuracy, so that the accuracy is high and the performance is stable when subpackaging is carried out on the liquid. The liquid outlet needle is arranged at a liquid outlet hole, so that the pressure in a pipeline can be reduced; and due to the small-hole design of the needle, the charging and measuring accuracy can be guaranteed. The high-viscosity liquid precise subpackaging device can be used for subpackaging in a laboratory and large-scale industrial charging, and is low in cost and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the field of biological and chemical machinery, in particular to a high-viscosity liquid precision packaging device. Background technique [0002] At present, the existing dispensing equipment for high-viscosity liquids in the domestic market mainly includes peristaltic pump dispensing, pipette gun manual dispensing, etc. Among them, the silicone tube used in the working process of the peristaltic pump is elastic. When the liquid with high viscosity and poor fluidity is needed, when the peristaltic pump is rotated to squeeze out the liquid, due to the poor fluidity of the product with high viscosity, it will be in the silicone tube. Due to a certain pressure on the surface, the silicone tube will deform with the change of pressure and affect the filling accuracy. Therefore, the peristaltic pump can dispense liquids with high viscosity and poor fluidity, but the accuracy cannot be too high. However, manual pipette guns are lim...
