Filling machine is mainly a small class of packaging machinery products, from the perspective of the packaging of materials can be divided into liquid filling machine, paste filling machine, powder filling machine, particle filling machine; from the degree of automation to produce Is divided into semi-automatic filling machine and automatic filling production line, automatic filling machine use and maintenance details are as follows. First, the automatic filling machine filling accuracy adjustment 1. Filling error mainly by the filling volume, filling speed, the upper and lower valve switch speed to determine. Up and down the valve switching speed and the viscosity of the product, the greater the viscosity, the valve switch speed slower. 2. Adjust the valve spring pressure should be measured by filling the amount of measurement and the operator's experience to determine. 3. The pressure of the thickening valve mainly adjusts the spring pressure of the valve. Spring pressure increases, the valve switch speed to speed up.
