In order to improve the production efficiency of the flexible tube packaging product, a filling and sealing machine is often adopted for production. In the production process of the hose packaging article, the material is injected into the hose without sealing the tail, and then the tail of the hose is heated and sealed. Since various characters and patterns are often present on the hose, the hose is cylindrical before the tail is sealed, and the tail part is flat after the tail is sealed, and the front and the rear of the hose are clearly formed, the patterns are also displayed on the two surfaces. In order to ensure that the pattern can be displayed on the correct position of the surface of the hose after the hose is subjected to tail sealing, the position of the hose must be correctly placed before the hose enters the heating and tail sealing process, and the display position of the pattern is prevented from being wrong.
