[0027] Example 1

[0028] This embodiment discloses a bag delivery mechanism as a preferred implementation of the technical solution. Figure 1As shown, it includes a moving guide unit, a slide unit, a bag body straightening unit, a bag placing panel 25 and a vacuum bag opening unit.

[0029] Among them, the slide unit is slidably connected to the movable guide unit, and a plurality of hollow columns 1 are arranged on the top of the slide unit; a plurality of connecting columns 2 corresponding to the hollow columns 1 are arranged at the bottom of the bag placing panel 25, and the connecting columns 2 are inserted into the hollow columns 1, so that the bag placing panel 25 and the slide unit can be detachably connected.

[0030] More specifically, the bag body straightening unit is installed on the slide unit, including a synchronous control component and two straightening components; a straightening guide hole unit is provided on the bag placing panel 25, and the two straightening components are movably connected to the synchronous control components respectively, and pass through the straightening guide hole unit from the bottom of the bag placing panel 25, and are opened and closed reciprocatingly along the straightening guide hole unit based on the control of the synchronous control component.

[0032] Based on the structure of the above-mentioned bag delivery mechanism, its working principle is as follows: after placing the packaging bag on the bag placement panel 25, start the mobile guide unit to transport the slide unit, the bag body straightening unit, the bag placement panel 25, the lower lifting suction cup assembly and the packaging bag to the target position.

[0033] This technical solution improves the automation level of the equipment by setting up a bag straightening unit instead of manually straightening the packaging bag; in addition, based on the above working principle, compared with the prior art, this technical solution does not need to set up related structures such as bag pressing cylinders, and the structural composition and equipment control are relatively simple. Furthermore, the bag placing panel 25 of this technical solution and the slide unit are detachably connected through the cooperation of the hollow column 1 and the connecting column 2, and no other auxiliary tools are required during disassembly, which is convenient for assembly, disassembly, cleaning and maintenance.

[0034] Example 2

[0035] This embodiment discloses a bag delivery mechanism as a preferred implementation of the technical solution. Figure 1As shown, it includes a moving guide unit, a slide unit, a bag body straightening unit, a bag placing panel 25 and a vacuum bag opening unit.

[0036] Among them, the mobile guide unit includes a guide assembly and a drive assembly. The guide assembly includes a first mounting seat 4, a second mounting seat 5 and two parallel guide rods 6; the two ends of the two guide rods 6 are fixedly connected to the first mounting seat 4 and the second mounting seat 5 respectively.

[0037] Based on the structure of the above-mentioned mobile guide unit, the slide unit is slidably connected with the mobile guide unit, specifically, slidably connected with the two guide rods 6 of the guide assembly, and fixedly connected with the transmission belt 7 of the drive assembly. Based on this, its working principle is: start the drive motor 8, the drive motor 8 drives the driving wheel assembly 9 to rotate, and the transmission belt 7 and the driven wheel assembly 10 rotate synchronously therewith. During this period, the transmission belt 7 pulls the slide unit to make a linear motion along the guide rod 6. On this basis, by changing the optional installation direction of the drive motor 8 shaft, the moving direction of the slide unit can be further changed.

[0038] A plurality of hollow columns 1 are arranged on the top of the slide unit; a plurality of connecting columns 2 corresponding to the hollow columns 1 are arranged at the bottom of the bag placing panel 25, and the connecting columns 2 are inserted into the hollow columns 1, so that the bag placing panel 25 and the slide unit can be detachably connected. More specifically, four hollow columns 1 and four connecting columns 2 can be arranged, and further, the four hollow columns 1 are arranged in a rectangular orientation on the slide unit, and the four connecting columns 2 are arranged in a rectangular orientation at the bottom of the bag placing panel 25 corresponding to the four hollow columns 1, so that the bag placing panel 25 can be stably installed.

Furthermore, since the two guide rods 6 are fixed by the first mounting seat 4 and the second mounting seat 5, the two rows of snap-in wheel assemblies 27 are fixed in relative position based on the assembly platform seat 26, and the two rows of snap-in wheel assemblies 27 are arranged between the two guide rods 6, and snap-fitted between the two guide rods 6 to ensure the stability of the structure and effectively prevent the slide unit from derailing.
