Problems solved by technology
However, due to the high transmission efficiency of diaphragm pumps, filtration devices and other equipment, the pressure of the conveyed liquid is high, resulting in a high pressure at the outlet valve, which will directly impact the filling container and weighing system
Causes the weighing system to lift forward and output the feedback signal
For example, when filling 50kg, due to the existence of the impact force, a feedback signal will be given at 49kg, and the filling will stop, resulting in inaccurate weight of the filling liquid.
Moreover, due to the high pressure and high flow rate of the liquid to be transported, although the work has stopped, there is still a certain distance between the valve port and the container for high-speed fluid. This section of liquid cannot be calculated, resulting in waste of materials.

A high-precision filling device includes a bracket, a diaphragm pump, a delivery pipe, a filter, an adjustment mechanism, a filling mechanism, a weighing mechanism, and a control module. The regulating mechanism is provided with two ball valves, so as to divide a high-pressure and high-speed fluid into a high-pressure and high-speed fluid and a low-pressure and low-speed fluid. The filling mechanism includes a filling valve and a cylinder for driving the filling valve to work. The filling valve includes a first feed pipe, a second feed pipe, a discharge pipe, a piston, and a spring, and the cylinder is controlled by the control module so that the cylinder drives the piston to reciprocate and translate to block the first feed pipe Or the second feed pipe or discharge pipe to achieve three different station structures, so as to realize the filling method of high-speed filling first and then slow filling, and solve the negative impact of the impact force of high-speed fluid to ensure precision.
Description
technical field [0001] The invention relates to the technical field of filling, in particular to a high-precision filling device. Background technique [0002] A filling machine is a widely used production device for filling liquids. Most of the existing filling machines place the filling container on the weighing mechanism. When the liquid is added to the required weight, the weighing mechanism sends a feedback signal to stop the filling. However, due to the high transmission efficiency of diaphragm pumps, filtration devices and other equipment, the pressure of the transported liquid is high, resulting in a high pressure at the outlet valve, which will directly impact the filling container and weighing system. Cause the weighing system to lift forward and send out the feedback signal. For example, when filling 50kg, due to the existence of the impact force, a feedback signal will be given at 49kg, and the filling will stop, resulting in inaccurate weight of the filling li...
