The tube filling and sealing machine is widely used in the packaging of cosmetics, toothpaste, ointment and other contents in the form of packaging. One of the factors to measure the quality of the filling and sealing machine is the filling accuracy. Generally, a qualified hose filling and sealing machine should ensure the filling accuracy of plus or minus one percent. In order to ensure better filling accuracy, filling and sealing machine manufacturers generally adopt a matching and better filling system according to the customer's material characteristics and filling volume.

However, in the process of use, customers sometimes find that the filling accuracy of the filling and sealing machine is not satisfactory. In the actual use process, in order to ensure the filling accuracy, as a user, you need to pay attention to several aspects:

First, before the hose filling and sealing machine runs, the metering pump needs to be turned on for a few minutes to remove air bubbles in the filling rotary valve tube. The filling accuracy can only be guaranteed when the filling air pressure is stable and the material is not sprayed during filling.

Second, if the filling and sealing machine cannot defoaming for a long time during the filling process, it is necessary to check whether there is air leakage in the filling pump, whether there is a problem with the piston sealing ring in the filling cylinder, and Is there a problem with other seals.

Third, if there are many particles and impurities in the filling material, and the filling accuracy is inaccurate, it is necessary to check whether there are impurities stuck in the valve sheet, which will cause the one-way valve to close incompletely, making the filling process impossible. The amount is not allowed.
