[0027] When the guide rod 23 moves upward, the guide rod 23 lifts the bag-making material so that the bag-making material and the handle are separated from the workbench 20, thereby preventing the bag-making material and the handle from being attached to the workbench 20 and affecting the transmission of the bag-making material, thereby ensuring production efficiency.

[0031] Furthermore, in this embodiment, Figure 9 As shown, the first push block 281 is connected to the movable rod of the first pushing cylinder 28. In fact, the front side of the first push block 281 is also connected to a baffle 282. The baffle 282 is located above the positioning groove and cooperates with the positioning groove 24 to prevent the handle from falling.

[0032] Furthermore, in this embodiment, Figure 1 、 Figure 7 as well as Figure 8 As shown, a pressing mechanism 4 is also installed on the machine base 1, and the pressing mechanism 4 is arranged on one side of the handle positioning mechanism 2. The pressing mechanism 4 includes a support platform 42 slidably connected to the machine base 1 through a second slide 41, a lower mold part 43 and a second upper mold part 44 arranged on one side of the support platform 42 and cooperating with each other, the lower mold part 43 includes a third cylinder 431 and a lower mold base 432 connected to each other, the second upper mold part 44 includes a second cylinder 441 and a second upper mold base 442 connected to each other, the second upper mold base 442 cooperates with the lower mold base 432, and the bottom of the second upper mold base 442 is provided with a pressing mold adapted to the shape of the handle, and a pad 4321 is installed on the top of the lower mold base 432, and the pad 4321 is provided with an annular groove 4322 adapted to the shape contour of the handle, and the second upper mold base 442 and the lower mold base 432 are both equipped with heating rods.

[0033] In the past, bag-making machines usually used a one-time method to hot-press and fasten the handle to the corresponding position of the bag-making material. However, in order to ensure that the tightness between the handle and the bag-making material meets the requirements, the hot-pressing time needs to be sufficient. In this way, the operation cycle of the handle fastening process will be prolonged, reducing production efficiency. In order to improve production efficiency and ensure the handle fastening effect, the handle positioning mechanism 2 is first used to position the handle to the corresponding installation hole of the bag-making material, and then the pressing mechanism 4 is used to press the handle and the bag-making material for a second time. By performing the two pressing operations, the time required for a single pressing operation can be reduced accordingly, and multiple handles can be fastened in the same production cycle, thereby improving production efficiency.

[0034] Specifically, a pair of crescent-shaped pressing dies 2221 are provided at the bottom of the first upper die base 222 of the handle positioning mechanism 2. The first upper die part 22 presses the corresponding position of the bag-making material down to the positioning groove 24 on the workbench 20 through the crescent-shaped pressing dies 2221. Under the action of equal pressure, the crescent-shaped pressing dies 2221 are used for pressing. The actual force-bearing area of the bag-making material and the handle is reduced, and the external force on the force-bearing part is increased. The increased pressure enhances the pressing effect, which can shorten the pressing time. Afterwards, the bag-making material and the entire handle are pressed together by the pressing mechanism 4 to complete the buckling operation. Since the pressing has been performed once by the handle positioning mechanism 2, the pressing time can be shortened accordingly when the pressing is performed by the pressing mechanism 4. Compared with the previous operation, the pressing operation of the handle and the bag-making material is divided into two times. In this way, multiple handles can be buckled in the same time, and the pressing effect can also be enhanced.

[0035] Furthermore, in this embodiment, Figure 7 and Figure 8 As shown, a second adjustment shaft 411 is movably connected to one side of the second slide 41, and second gears 412 are fixedly connected to both ends of the second adjustment shaft 411. The second gear 412 cooperates with the rack 11 of the machine base 1, and a second handle 413 is also connected to one end of the second adjustment shaft 411; the second slide 41 is also equipped with a second guide rail 414 and a second lead screw 415, and a second guide slider 416 and a second nut block 417 that cooperate with the second guide rail 414 and the second lead screw 415 respectively are installed at the bottom of the support platform 42, and one end of the second lead screw 415 is also connected to a second hand-cranked wheel 418.

[0036] Furthermore, in this embodiment, Figure 1 and Figure 2As shown, a transmission part 5 is further provided between the handle positioning mechanism 2 and the pressing mechanism 4, and the transmission part 5 is slidably connected to the machine base 1. The transmission part 5 includes an upper roller 51 and a lower roller 52 that cooperate with each other, two connecting plates 53 connected to the upper roller 51 and the lower roller 52 at both ends, and an adjusting shaft 54 connected to the two connecting plates 53.
