[0033] See also Fig.12 As shown, the frame assembly 4 includes a second support frame 401 and a linear guide rail 402 connected together; the linear guide rail 402 is installed on the second support frame 401.

[0034] The operation process is as follows: the material bag passes through two sets of transverse sealing mechanisms 1 from the top of the mechanism. The first set of first servo motors 1046 operates, and the transmission shaft 1041 drives the first connecting rod 10412 and the second connecting rod 10417 to move, pushing the transverse sealing rear sealing group 101 and the transverse sealing front sealing group 102 to clamp the material bag to open and close. When the upper first set of transverse sealing mechanisms 1 is closed, the heating rod inside the mechanism conducts heat to the sealing head 1017 and the sealing block 1024. The surface of the sealing head 1017 is vertical lines 10171, which heats the edge of the material bag, so that the material bag is sealed and vertical lines are formed at the mouth of the material bag. This process can drive the liquid material in the material bag to the two ends of the sealing to avoid the appearance of liquid trapped bubbles after complete sealing. After the mechanism completes clamping the bag, the second servo motor 205 of the stepper transmission group 2 drives the ball screw 201 to rotate, and the ball screw nut 202 drives the transverse sealing mechanism 1 and the bag to move downward along the linear guide 402 by a distance X, where X is less than the length of the bag. Then the transverse sealing mechanism 1 clamps and releases, and the second servo motor 205 drives the transverse sealing mechanism 1 to move upward along the linear guide 402. The first group of transverse sealing mechanisms 1 on the upper layer clamps and releases, while the second group of transverse sealing mechanisms 1 closes and clamps the bag to heat it, and performs the second sealing of the other end of the bag. The surface of the sealing head 1017 of the second group of transverse sealing mechanisms 1 is a transverse pattern 10171, which is formed at the mouth of the bag after heating and shaping. In this way, it is combined with the vertical pattern formed by the first group of transverse sealing mechanisms 1 to form a mesh pattern. Then the second group of stepper transmission groups 2 drives the second group of transverse sealing mechanisms 1 to move downward along the linear guide 402 by a distance Y, the length of the bag width, and then releases. The sum of X and Y is the length of one bag. That is, the upper and lower transverse sealing mechanisms 1 are moved closer or farther away from each other, and the clamping and releasing states of the two transverse sealing mechanisms 1 cannot be the same, that is, one group of transverse sealing mechanisms 1 clamps, and the other group of transverse sealing mechanisms 1 releases.
