Description
Technical Field
The invention relates to the technical field of filling, in particular to a large-flow high-precision filling device.
Background
The liquid filling machine is mainly a small class of products in a packaging machine, and is widely applied to laboratory chemical reagents and industrial production of liquid packaging products.
The high-precision filling machine (piston type) of the automatic line at the present stage is suitable for smaller product specifications. For large-size products, normal pressure filling is mostly adopted. When a normal pressure type filling machine is adopted to fill large-specification products, two filling modes are generally available: a. filling time control mode: the flow rate is slow, the filling time is long, and the production efficiency is low; the fluidity (viscosity) of the materials changes with the environmental temperature, the liquid level disturbance during the material supplementing of the material box and the like, so that the filling precision is low. b. An online weighing control mode: the flow rate is slow, the filling time is long, and the production efficiency is low; chemical product materials or emitted gas have certain corrosivity on the weighing module, and the failure frequency is high.
The micro peristaltic pump is applied to a plurality of laboratories, and is widely applied to places with higher requirements such as laboratories due to the characteristics of no contact with liquid, wide working viscosity range, no pollution, high precision, good sealing performance and backflow.
The application of the large-flow peristaltic pump in the industry mainly has two aspects: a. the pump is used as a chemical pump by utilizing the characteristics of no contact with liquid, wide working viscosity range, no pollution, good sealing property and backflow. And can adopt single or multiple pump heads according to the requirement of the pumping flow; b. the device has the characteristics of quantitative output, no contact with fluid, wide working viscosity range, no pollution and good sealing performance, and can be used as a large-scale chemical product filling device for matching. Generally, the filling is carried out by adopting a time control peristaltic pump start-stop mode, but the peristaltic pump is not suitable for large-batch high-precision filling production of an automatic production line due to low production efficiency, low filling precision, high failure frequency and the like, so the peristaltic pump is rarely applied in the field of industrial filling. The reasons for this problem are: the method is not suitable for multi-pump head multi-path filling when the filling is carried out in a starting and stopping mode of the time control peristaltic pump. Because the flow difference of each pump head during working controls different stop time nodes of the peristaltic pump, only single-pump-head single-path filling can be adopted, and the production efficiency is low; when filling is carried out in a time control peristaltic pump start-stop mode, the fluctuation of the rotating speed of the peristaltic pump is caused by the fluctuation of the voltage and the frequency of a power supply; when the peristaltic pump is started and stopped every time, the starting and stopping phases are different, so that the flow rate at the starting and stopping time is correspondingly changed, and the filling precision is low; when the peristaltic pump is started, the impact current and the impact torque are large, and high-frequency impact caused by frequent starting and stopping is caused, so that the failure frequency is high.

a filling operation mode: when the photoelectric switch detects that the filling container is in place, the liquid level of a material box is controlled to be output → the operation controller is triggered to operate to output, and simultaneously the pulse number of an encoder is read → the pneumatic two-position three-way ball valve and the pneumatic anti-drip filling head act to start filling, the material is filled from the material box → the feeding pipe → the pump head → the pneumatic two-position three-way ball valve → the anti-drip filling head → the liquid filling container, when the pulse number read from the encoder by the operation controller reaches a filling amount set value → the pneumatic two-position three-way ball valve and the pneumatic anti-drip filling head act to stop filling, the operation controller automatically enters an idle;
liquid level control mode: when the liquid level gauge detects that the liquid level of the bin reaches the lower limit or the upper limit of the control liquid level → the output of the trigger operation controller → the pneumatic two-position two-way ball valve acts to feed or stop feeding.
