[0007] Preferably, observation windows 15 are provided on the support frame 16 and on both sides of the transverse sealing and pressing angle heating device 9 .

[0008] Preferably, the transverse sealing angle heating device 9 sends the combined film to the upper traction device 18 through the guide mechanism on the support frame 16, and then transmits it to the longitudinal sealing heating and cooling device 6 from right to left in sequence.

[0009] Compared with the prior art, the utility model has the beneficial effect that components such as the zipper heating and cooling device are arranged above the production line, thereby reducing the total length of the production line and reducing the floor space.
