The tube filling and sealing machine is widely used in the packagi✘★ ₽ng of cosmetics, toothpaste, ointment and othπ£er contents in the form of packaging. ✔π∞One of the factors to measure the quality£‌ of the filling and sealing machine is the filli♦©ng accuracy. Generally, a qualified ✘∏‌≤hose filling and seali∑₩¶ ng machine should ensure the  &‍filling accuracy of plus or✘ ←' minus one percent. In order to ensure bγ∏‍₩etter filling accuracy, filling and sealing m€∏achine manufacturers generally adopt a&€σ matching and better filling system β↕>®according to the customer's material  ¥σcharacteristics and filling voβ≈lume.

However, in the process of use, customers somσ ✘∑etimes find that the filling accuracy of the fi‍β®σlling and sealing machine is not satisf>•↕×actory. In the actual use process, in or•∞der to ensure the filling accuracy, ♥§≈ as a user, you need to pay attentφ∑ion 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 caΩ δn only be guaranteed £ ✘≥when the filling air pressure is stable and the m♠↓aterial is not spray≤γ ed during filling.

Second, if the filling a♥'nd sealing machine cannot d☆π₹​efoaming for a long time during the ∑×♥filling process, it is necess•★©≥ary to check whether ther÷★γe is air leakage in the filling pump,↑®> whether there is a problem ↔¶with the piston sealing r¶≤'εing in the filling cylinder, and Is →♥→←there a problem with other seals.

Third, if there are many particles and i↕¥σ§mpurities in the filling material, and thλ≈•≤e filling accuracy is inaccurate¶​, it is necessary to check©★ whether there are impuritie×β↓σs stuck in the valve sheet, w$σ≈‍hich will cause the one♦♣-way valve to close incompletely×®♠ , making the filling process im♥&↔possible.
