[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1 to 5 The present invention discloses a plastic bag making machine that facilitates processing of multiple sizes, comprising a frame 1, a conveyor belt 2 at one end of the frame 1, a lower mold 3 at the other end of the frame 1, positioning bolts 4 threadedly connected to the lower mold 3 on both sides of the frame 1 near the lower mold 3, a stamping groove 5 at the top end of the lower mold 3, a U-shaped support frame 6 fixedly installed at the top end of the frame 1 near the lower mold 3, a hydraulic rod 7 penetrating through the middle of the top of the U-shaped support frame 6, a connector 8 fixedly installed at the bottom end of the hydraulic rod 7, a stamping upper mold 9 at the bottom end of the connector 8, a connecting sleeve 10 fixedly installed at the middle of the top of the stamping upper mold 9 and connected to the connector 8, a plurality of positioning bolts 11 threadedly connected to the connector 8 on the side of the connecting sleeve 10, and an auxiliary support assembly 12 installed at the end of the frame 1 near the lower mold 3.

[0023] The lower die 3 is inserted into the frame 1 and can be locked by positioning bolt 4. When disassembling, loosen positioning bolt 4 and pull out the lower die 3. The connecting sleeve 10 is connected to the connecting head 8 and locked by positioning bolt 11, which can be used to install the upper stamping die 9. When disassembling, loosen the upper stamping die 9 and separate the connecting sleeve 10 from the connecting head 8. By replacing different lower dies 3 and upper stamping dies 9, handles of different sizes of plastic bags can be stamped.

[0024] Limiting grooves 13 are provided on both sides of one end of the frame 1. Limiting strips 14 that are slidably connected to the limiting grooves 13 are fixedly provided on both sides of the lower mold 3, which can limit the lower mold 3 and improve the stability of the lower mold 3.

[0025] The upper stamping die 9 is composed of a support plate 15, a stamping cutter head 16, a limiting pressure frame 17, four limiting rods 18 and four springs 19. The support plate 15 is fixedly connected to the connecting sleeve 10. The stamping cutter head 16 is fixedly connected to the middle position of the bottom end of the support plate 15. The four limiting rods 18 slide through the four corners of the support plate 15 respectively. The limiting pressure frame 17 is fixedly connected to the bottom end of the limiting rods 18. The four springs 19 are respectively sleeved on the four limiting rods 18 and located between the support plate 15 and the limiting pressure frame 17.

[0026] During the stamping process, the limiting frame 17 is attached to the edge of the plastic bag and presses and limits the plastic bag. The limiting rod 18 and spring 19 achieve limiting and buffering. The stamping cutter head 16 cooperates with the stamping groove 5 to stamp and remove the excess part of the plastic bag, thereby forming a handle.

[0027] The auxiliary support assembly 12 consists of a stroke cylinder 20, a support vertical plate 21, and an auxiliary support platform 22. One end of the stroke cylinder 20 is fixedly connected to the frame 1, the support vertical plate 21 is fixedly connected to the other end of the stroke cylinder 20, and the auxiliary support platform 22 is fixedly connected to the top of the support vertical plate 21.

[0028] Before the plastic bag moves to the stamping position, the auxiliary support platform 22 is positioned directly above the lower die 3. At this time, one end of the plastic bag moves off the conveyor belt 2 and to the top of the auxiliary support platform 22. When the plastic bag is in place, the conveyor belt 2 stops moving, and the stroke cylinder 20 drives the support vertical plate 21 and the auxiliary support platform 22 to move off the bottom of the plastic bag, so that the plastic bag is positioned at the top of the lower die 3.

[0029] The top of the auxiliary support platform 22 is rotatably equipped with several universal ball bearings 23. The height of the auxiliary support platform 22 is greater than the height of the lower mold 3, which can reduce the friction between the auxiliary support platform 22 and the plastic bag, making it easier for the plastic bag to move to the top of the auxiliary support platform 22 and also making it easier for the auxiliary support platform 22 to separate from the plastic bag.

[0030] During operation, the lower die can be locked and positioned by the first positioning bolt, and it can also be disassembled. The upper die can be disassembled and replaced as a whole by the connecting head, connecting sleeve, and second positioning bolt. By installing lower dies and upper dies of different sizes, it is convenient to make handles for plastic bags of different sizes. The upper die, consisting of a support plate, a stamping cutter head, a limiting pressure frame, four limiting rods, and four springs, can cooperate with the lower die to stamp the handles of the plastic bags. During the stamping process, the limiting pressure frame can press and limit the edges of the plastic bags, improving the stability of the stamping operation. The auxiliary support assembly, consisting of a stroke cylinder, a support vertical plate, and an auxiliary support platform, can provide auxiliary support for the plastic bags, allowing the handle end of the plastic bags to reach the stamping position. The universal ball bearings can reduce the friction between the auxiliary support platform and the plastic bags, making it easy to separate the auxiliary support platform from the plastic bags.
