Sealing device for glass freeze-drying pipe and working method of sealing device

The invention discloses a sealing device for a glass freeze-drying pipe and a working method of the sealing device. The sealing device comprises a main control circuit board module, a display touch screen module, a flame gun control motor module, at least one flame gun, a flame gun mounting rail, an adjustable clamping device, a gas pressure gauge and a sealing head. The method comprises the following steps: collecting information of a to-be-sealed glass freeze-drying tube; according to the information of the to-be-sealed glass freeze-drying pipe, controlling a flame spray gun to carry out heat sealing test on the to-be-sealed glass freeze-drying pipe; adjusting the position of a flame spray gun according to a test result; the test result meets the preset optimal sealing environment data; and the sealing work of the to-be-sealed glass freeze-drying pipe is completed. The heat sealing time can be shortened, the difference uncertainty of the sealing position is reduced, and then the heat sealing effect is impro
