[0002] The tubular film bag making and packaging machine is a device that uses tubular film to make bags and automatically unload and package. The existing tubular film bag making and packaging machine mainly includes a bag making mechanism, an unloading mechanism and a heat sealing mechanism. The bag making mechanism is arranged directly below the unloading mechanism, so that after the bag making mechanism completes bag making, the unloading mechanism is used to unload the newly produced packaging bags, and then the heat sealing mechanism is used for packaging.

[0023] By adopting this embodiment, the bag making station and the unloading station are connected by the bag feeding translation mechanism 5, and the bag making station and the unloading station can be arranged side by side at the same height, which is convenient for manual feeding and other operations; on the other hand, the first heat sealing mechanism 3 and the film cutting mechanism 4 of the bag making station can independently complete the film taking and bag making work, and the bag opening mechanism 6, the unloading mechanism 7 and the second heat sealing mechanism 10 can independently complete the bag opening and unloading work, and the two groups of work can be carried out simultaneously, which greatly improves the packaging efficiency.

[0024] Combination Figure 3As shown, preferably, the film cutting mechanism 4 includes a cutting disc 41, a cutting motor 42, a first limiting beam 43, a second limiting beam 44 and a cutting drive mechanism 45; the first limiting beam 43 has a cutting groove 431 that runs through the front and back, the second limiting beam 44 is arranged in parallel in front of the first limiting beam 43, and the second limiting beam 44 is provided with an avoidance groove 441; the cutting disc 41 is arranged on the cutting motor 42, and the cutting drive mechanism 45 is used to drive the cutting disc 41 to move along the cutting groove 431.

[0025] It should be noted that the cutting motor 42 is used to drive the cutting disc 41 to rotate and cut the packaging film, which can ensure that the cut is neat. In order to adapt to packaging films of different materials, a first limiting beam 43 and a second limiting beam 44 are also provided in front of the cutting disc 41. The packaging film passes through the gap between the first limiting beam 43 and the second limiting beam 44, which can ensure that the packaging film is flat and wrinkle-free.

[0026] like Figure 4 As shown, in order to reliably adsorb the packaging bag, the first vacuum suction cup 55 and the second vacuum suction cup 62 are arranged on the corresponding suction cup seat 56, and the suction cup seat 56 includes a horizontally extending side mounting plate 561 and a top mounting plate 562 extending upward from the center of the side mounting plate 561. Both sides of the side mounting plate 561 and the upper part of the top mounting plate 562 are provided with mounting holes 563, and the mounting holes 563 are used to correspondingly install the first vacuum suction cup 55 or the second vacuum suction cup 62. During operation, the vacuum suction cups on both sides of the side mounting plate 561 suck the edges on both sides of the middle and upper part of the packaging bag as the main force application points and positioning points; the vacuum suction cups on the top mounting plate 562 suck the upper central area of ​​the packaging bag to open the bag mouth and form a predetermined opening shape to ensure stable material discharge.

[0027] Combination Figure 6As shown, in some embodiments, a flapping mechanism 8 is further provided directly below the unloading mechanism 7, and the flapping mechanism 8 includes a flapping plate 81, a swing shaft 82, a driving rack 83, and a flapping driving cylinder 84. The flapping plate 81 is connected to the frame 1 through the swing shaft 82, and a driving gear 85 is further provided on the swing shaft 82 of the flapping plate 81, and the driving gear 85 is meshed with the driving rack 83. The flapping driving cylinder 84 is connected to the driving rack 83 to drive the driving rack 83 to rise and fall, thereby driving the flapping plate 81 to swing up and down. During the loading process, the flapping plate 81 swings up and down, flaps the bottom of the packaging bag, and ensures that the material is gathered at the lower part of the packaging bag, which is convenient for the subsequent upper sealing work.

[0028] Based on the above invention concept, the same side of the bag feeding translation mechanism 5 is provided with a non-overlapping bag making area and a material unloading area, the tube film frame 2, the first heat sealing mechanism 3 and the film cutting mechanism 4 are arranged at different heights of the bag making area; the bag opening mechanism 6, the material unloading mechanism 7 and the second heat sealing mechanism 10 are arranged at different heights of the material unloading area. Through the spatial arrangement of the above mechanisms, a smooth bag making and packaging process chain can be formed, and each mechanism is interconnected and connected in space, which reduces space occupation and improves work efficiency.

[0029] Preferably, the first heat sealing mechanism 3 and the second heat sealing mechanism 10 both include a heating block 31 and a heat sealing cylinder 32, the heat sealing cylinder 32 is connected to the heating block 31, the two heating blocks 31 are symmetrically arranged, and can be driven by the heat sealing cylinder 32 to move closer to or away from each other.

[0030] In order to drive the packaging film to move between different mechanisms, the packaging machine also includes a labeling mechanism 9, which includes a label paper 95, a traction roller 91, a traction motor 92, a pressure roller 93 and a pressure swing arm 94. The traction motor 92 is connected to the traction roller 91 to drive the traction roller 91 to rotate; the pressure swing arm 94 is connected to the pressure roller 93 to drive the pressure roller 93 to produce a tendency to approach the traction roller 91, thereby clamping the label paper 95 between the pressure roller 93 and the traction roller 91, so that the traction roller 91 can pull the label forward by its own rotation, and the label is attached to the packaging film by an additional labeling cylinder.

[0031] The working principle of this bag making and packaging machine is as follows:

[0032] First, place the rolled tubular film on the tubular film rack 2, and make it pass through the film guide roller 21 and the first heat sealing mechanism 3 in sequence. The heat sealing mechanism heat-seals the tubular film to form the bottom of the packaging bag. After the tubular film passes through the film guide roller 21, the labeling mechanism 9 performs a labeling operation on the tubular film. The heat-sealed packaging film continues to move forward and enters the film cutting mechanism 4. After a predetermined length is sent out from the bottom of the film cutting mechanism 4, the first vacuum suction cup 55 of the bag feeding translation mechanism 5 sucks the packaging film, and the film cutting mechanism 4 cuts off the top of the packaging film. The bag feeding translation mechanism 5 translates the packaging bag and sends it to the bottom of the unloading mechanism 7; combined with Figure 7 As shown, the horizontal telescopic cylinder 61 of the bag opening mechanism 6 drives the second vacuum suction cup 62 to extend, suck the other side surface of the packaging bag, and open the packaging bag; the lifting cylinder 72 of the unloading mechanism 7 drives the unloading barrel 71 to descend, so that the guide plate 73 extends into the bag opening of the packaging bag for loading. After the loading is completed, the lifting cylinder 72 rises, the guide plate 73 leaves the packaging bag, and the second heat sealing mechanism 10 seals the bag opening, and the packaging is completed.

[0033] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
