[0033] Please see Figure 1 and Figure 2 The embodiments of this application relate to a zipper bag making device 10, including a support component 100, a film feeding component 200 and a heat sealing component 300. The film feeding component 200 is disposed on the support component 100 and the film feeding component 200 transfers the bag film. The heat sealing component 300 is disposed on the film feeding component 200 and the heat sealing component 300 is used to seal the edges of the bag film.

[0034] The support assembly 100 includes a first base 110 and a second base 120 disposed opposite to each other, and a receiving space for receiving the bag film is formed between the first base 110 and the second base 120.

[0035] The film feeding assembly 200 includes a first conveyor belt assembly 210 disposed on a first base 110 and a second conveyor belt assembly 220 disposed on a second base 120. The first conveyor belt assembly 210 and the second conveyor belt assembly 220 are disposed opposite to each other and are capable of driving the bag film to move along a first direction. Specifically, the bag film includes two connecting pieces, and the first conveyor belt assembly 210 and the second conveyor belt assembly 220 respectively drive one connecting piece to move. The first direction is parallel to the height direction of the first base 110 and the second base 120.

[0036] The heat-sealing assembly 300 includes a first driving member 310, a pressing member 320, and a heat-sealing member 330, both extending along a first direction. The pressing member 320 is movably disposed on the side of the first base 110 near the receiving space, and the heat-sealing member 330 is disposed on the side of the second base 120 near the receiving space. The pressing member 320 and the heat-sealing member 330 are disposed opposite each other. The first conveyor belt assembly 210 and the second conveyor belt assembly 220 can transfer the bag film between the pressing member 320 and the heat-sealing member 330. The first driving member 310 is used to drive the pressing member 320 to move in a direction close to or away from the heat-sealing member 330, and the pressing member 320 can press the bag film against the heat-sealing member 330 so that the heat-sealing member 330 seals the edge of the bag film. The length of the heat-sealing member 330 is adapted to the length of the pressing member 320. Exemplarily, the heat-sealing member 330 uses a heating wire.

[0037] It should be noted that after the first conveyor belt assembly 210 and the second conveyor belt assembly 220 move the bag film a set distance along the first direction, the first conveyor belt assembly 210 and the second conveyor belt assembly 220 stop operating. Then, the first drive member 310 drives the pressing member 320 to move along the direction closer to the heat sealing member 330, so that the pressing member 320 presses the bag film against the heat sealing member 330, thereby causing the heat sealing member 330 to seal the edge of the bag film. After the edge sealing is completed, the first drive member 310 drives the pressing member 320 to move along the direction away from the heat sealing member 330. Then, the first conveyor belt assembly 210 and the second conveyor belt assembly 220 continue to move the bag film a set distance along the first direction, and so on.

[0038] By setting up the film feeding assembly 200, the first conveyor belt assembly 210 and the second conveyor belt assembly 220 can drive the bag film to move along the first direction to realize the transfer of the bag film; by setting up the heat sealing assembly 300, the first driving member 310 drives the pressing member 320 to move along the direction close to or away from the heat sealing member 330, so that during the transfer of the bag film, the first driving member 310 drives the pressing member 320 to press the bag film against the heat sealing member 330, so that the heat sealing member 330 seals the edge of the bag film, thereby realizing the integration of bag film transfer and edge sealing, and improving production efficiency.

The film feeding belt 224 is sleeved on the drive wheel 222 and the driven wheel 223 and is in frictional connection with the bag film.

[0040] The film feeding belt 224 of the first conveyor belt assembly 210 is disposed opposite to the film feeding belt 224 of the second conveyor belt assembly 220. When the second drive member 221 drives the drive wheel 222 to rotate, it can drive the driven wheel 223 and the film feeding belt 224 to rotate.

[0043] Please see Figure 1 and Figure 2 According to some embodiments of this application, optionally, a first tensioning block 400 is further provided on the first base 110. The first tensioning block 400 is adjustablely positioned on the first base 110 along a second direction, and the first tensioning block 400 can abut against the film feeding belt 224 on the first base 110 to adjust the tension of the film feeding belt 224 on the first base 110.

By rotating the first and second fasteners, the position of the first tensioning block 400 relative to the first base 110 and the position of the second tensioning block 500 relative to the second base 120 can be adjusted, thereby adjusting the tension of the film feeding belt 224 on the first base 110 and the second base 120.

[0048] Please see Figure 1 and Figure 2 According to some embodiments of this application, optionally, the first driving member 310 is disposed on the side of the first base 110 away from the receiving space, and a first through hole is formed in the first base 110. The power output end of the first driving member 310 passes through the first through hole and is connected to the pressing member 320. The axial direction of the first through hole is perpendicular to the extension direction of the pressing member 320. The first through hole extends through the first base 110. The first driving member 310 is a cylinder.

[0049] The first base 110 also has a second through hole. A guide rod 600 is connected to the side of the pressing member 320 near the first base 110.
