[0019] The adjusting screw 22 on the left and the guide column 23 on the right are symmetrically mounted on the upper and lower sides of the movable seat 3, and the movable seat 3 includes a mounting ring 31, and the inner circumference of the mounting ring 31 is provided with a motor fixing countersunk hole 311, and the left and right sides of the mounting ring 31 are fixedly connected to the fixing blocks 32, and the upper and lower side walls of the fixing block 32 on the left are provided with threaded holes 321, and the upper and lower side walls of the fixing block 32 on the right are provided with through holes 322, and the rotating shaft 41 of the sealing knife 4 is rotatably fixed by the mounting ring 31 of the movable seat 3, and the fixing block 32 on the left side of the movable seat 3 is mounted on the adjusting screw 221 on the left, and the fixing block 32 on the right side is mounted and slidably mounted on the guide column 23 on the right.

[0020] A set of mounting rings 31 facing each other front and back are rotatably connected to the front and back ends of the sealing tool 4 respectively. The sealing tool 4 includes a rotating shaft 41, on which a cutter head fixing plate 42 is fixedly mounted. The cutter head fixing plate 42 has an mounting groove 421 formed on its end surface. A heat sealing cutter head 43 is inserted into the mounting groove 421. The upper and lower sealing tools 4 rotate synchronously in opposite directions to achieve shear heat sealing of the packaging bag.

[0021] A conveyor belt 5 is arranged on the right plane between the upper and lower heat-sealing heads 43, and a controller 6 is installed on the base 1 below the conveyor belt 5. The controller 6 controls the conveyor belt 5 to transport the packaging bag to the left, and cooperates with the rotation frequency of the heat-sealing head 43 to realize the automatic sealing operation of the packaging bag.
