The first fixing base 4a has a first horizontal groove 4g formed therein, and the second fixing base 4b has a second horizontal groove 4h formed therein. The first horizontal groove 4g is mounted with a first latch 6, and the second horizontal groove 4h is mounted with a second latch 7.

[0026] The first latch 6 is covered with a first spring 8, one end of which abuts the first fixing seat 4a, and the other end of which abuts the first latch 6. The second latch 7 is covered with a second spring 9, one end of which abuts the second fixing seat 4b, and the other end of which abuts the second latch 7.

[0027] A first drive cylinder 10 is mounted on the first mounting base 4. The drive rod of the first drive cylinder 10 is connected to a first movable member 11. A vertical first slide groove 4c is provided on the inside of the first fixed base 4a, and a vertical second slide groove 4d is provided on the inside of the second fixed base 4b. The first movable member 11 slides into the first mounting base 4 along the first slide groove 4c and the second slide groove 4d, respectively.

[0028] A first folding piece 12 is provided beneath the first mounting seat 4. A first locating pin 13 and a second locating pin 14 are mounted on the first folding piece 12. The first fixing seat 4a is formed with a first locating slot 4e to accommodate the first locating pin 13, and the second fixing seat 4b is formed with a second locating slot 4f to accommodate the second locating pin 14.

[0032] To remove or replace the first folding piece 12, the first drive cylinder 10 drives the first movable member 11 upward. The leading end of the first movable member 11 releases the leading end of the first latch 6 and the leading end of the second latch 7. The trailing end of the first latch 6 releases the first positioning pin 13, and the trailing end of the second latch 7 releases the second positioning pin 14. The first folding piece 12 is then removed from the first mounting seat 4. A new folding piece of the appropriate size can then be installed in the same manner. The optimized transmission structure simplifies the process of removing or replacing the folding pieces, increasing the applicability of the folding device.

[0033] like Figure 4 As shown, the second bag folding assembly includes a second bag folding cylinder 15, a second movable part 23, a second mounting seat 17, and a second bag folding piece 24. The second movable part 23 fixes the second bag folding piece 24 under the second mounting seat 17, and the second bag folding cylinder 15 drives the second bag folding piece 24 to fold the bag.

[0034] A second bag-folding cylinder 15 is mounted on the bag-folding mounting base 1. A second bag-folding movable base 16 is slidably mounted on the bag-folding mounting base 1.

The fourth latch 19 is covered with a fourth spring 21, one end of the fourth spring 21 abuts against the second mounting seat 17, and the other end of the fourth spring 21 abuts against the fourth latch 19.

[0036] A second drive cylinder 22 is mounted on the second mounting base 17. The drive rod of the second drive cylinder 22 is connected to a second movable member 23. The ends of the second movable member 23 are provided with a first abutment 23a and a second abutment 23b. A third vertical slot 17a is provided on the left side of the second mounting base 17, and a fourth vertical slot 17b is provided on the right side of the second mounting base 17. The first abutment 23a is mounted on the left side of the second mounting base 17 along the third slot 17a, while the second abutment 23b is mounted on the right side of the second mounting base 17 along the fourth slot 17b.

[0037] A second folding piece 24 is provided beneath the second mounting base 17. A third locating pin 25 and a fourth locating pin 26 are mounted on one end of the second folding piece 24. The second mounting base 17 is formed with a vertically arranged third locating slot 17c and a fourth locating slot 17d. The third locating pin 25 has an inwardly recessed third annular groove 25a, while the fourth locating pin 26 has an inwardly recessed fourth annular groove 26a. The third locating pin 25 fits into the third locating slot 17c, with the third annular groove 25a aligned with the rear end of the third latch 18. The fourth locating pin 26 fits into the fourth locating slot 17d, with the fourth annular groove 26a aligned with the rear end of the fourth latch 19.

[0038] like Figure 5 As shown, the second folding piece 24 is installed in the second mounting seat 17 via the third positioning pin 25 and the fourth positioning pin 26. The tip of the third latch 18 is formed with a third curved surface 18a, and the tip of the fourth latch 19 is formed with a fourth curved surface 19a. The first abutting portion 23a of the second movable member 23 is formed with a third inclined surface 23c that cooperates with the third curved surface 18a, and the second abutting portion 23b is formed with a fourth inclined surface 23d that cooperates with the fourth curved surface 19a.

[0039] The second driving cylinder 22 drives the second movable member 23 downward, causing the first abutting portion 23a to abut the tip of the third latch 18, and the second abutting portion 23b to abut the tip of the fourth latch 19. The tail end of the third latch 18 inserts into the third annular groove 25a, securing the third positioning pin 25. The tail end of the fourth latch 19 inserts into the fourth annular groove 26a, securing the fourth positioning pin 26. The second folding piece 24 is fixed below the second mounting seat 17.

[0040] To remove or replace the second folding piece 24, the second drive cylinder 22 drives the second movable member 23 upward, causing the first abutment portion 23a to release the tip of the third latch 18, and the second abutment portion 23b to release the tip of the fourth latch 19. The tail end of the third latch 18 releases the third locating pin 25, and the tail end of the fourth latch 19 releases the fourth locating pin 26. The second folding piece 24 is then removed from the second mounting bracket 17, and a new folding piece of the appropriate size can be installed using the same procedure. Furthermore, the second folding assembly is smaller than the first, saving space and making it more suitable for smaller folding locations.

[0041] The best embodiment of the present invention has been described, and various changes or modifications made by ordinary technicians in this field will not depart from the scope of the present invention.
