How to deal with issues related to the filling accuracy of hose filling and sealing machines?

The hose filling and sealing machine is widely used in the packaging of cosmetics, toothpaste, ointments, and other contents in the form of hoses. One of the factors that measure the quality of the filling and sealing machine is the filling accuracy. Generally, qualified hose filling and sealing machines should ensure a filling accuracy of plus or minus one percent. In order to ensure better filling accuracy, manufacturers of filling and sealing machines generally adopt matching and better filling systems based on customer material characteristics and filling volume.

However, customers may sometimes find that the filling accuracy of the filling and sealing machine is not satisfactory during use. In practical use, in order to ensure filling accuracy, as a user, several aspects need to be noted:

Firstly, before the operation of the hose filling and sealing machine, the metering pump needs to be left idle for a few minutes to eliminate any air bubbles inside the filling valve tube. The filling accuracy can only be guaranteed when the filling pressure is stable and there is no spraying during filling.

Secondly, if the filling and sealing machine cannot eliminate bubbles in the tube for a long time during the filling process, it is necessary to check whether there is any leakage in the filling pump, whether there is a problem with the piston sealing ring in the filling material cylinder, and whether there are problems with other sealing parts.

Thirdly, if there are many particles and impurities in the filled material, and there is a problem of inaccurate filling accuracy, it is necessary to check whether there are impurities stuck in the valve plate, which leads to incomplete closure of the one-way valve and inaccurate filling volume.
