Detailed Implementation

[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, illustrates the present invention. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 The present invention provides a technical solution: a packaging bag opening device for a granule packaging machine, including a support base 1, a packaging machine body 2 fixedly connected to the front of the support base 1, a feeding hopper 6 fixedly connected to the bottom of the packaging machine body 2, a packaging bag body 3 movably connected to the inner bottom wall of the support base 1, a connecting plate 4 fixedly connected to one side of the support base 1, a sliding groove 15 opened on one side of the connecting plate 4, a slider 11 movably connected to the inner wall of the sliding groove 15, and a connecting sleeve 7 fixedly connected to one side of the slider 11.

[0023] A connecting ring 13 is movably connected to the inner wall of the connecting sleeve 7, and a hook 8 is fixedly connected to the outer wall of the connecting ring 13. A slot 16 is opened on the front of the support base 1. A motor 20 is fixedly connected to the inner bottom wall of the slot 16. A lead screw 19 is fixedly connected to the output shaft of the motor 20 through a coupling. A movable block 18 is movably connected to the outer wall of the lead screw 19. A connecting frame 17 is fixedly connected to the front of the movable block 18. A support frame 10 is fixedly connected to one end of the connecting frame 17. A support pad 9 is fixedly connected to the outer wall of the support frame 10. When packaging granules with a packaging bag, the packaging bag can be automatically opened, which facilitates the expansion of the bag opening for packaging. There is no need for the staff to manually open the packaging bag, which provides convenience for the use of the granule packaging machine and further improves the packaging efficiency of granules.

[0024] The shape and size of the expansion pad 9 are matched with the shape and size of the main body 3 of the packaging bag. The expansion pad 9 is a rubber expansion pad, which can improve the anti-slip effect when the expansion frame 10 expands the main body 3 of the packaging bag, thereby ensuring the expansion effect of the main body 3 of the packaging bag.

[0025] The outer wall of the slider 11 is slidably connected to the inner wall of the slide groove 15. The slider 11 is slidably connected to the connecting plate 4 through the slide groove 15. The main body of the packaging bag 3 can be stretched and unfolded by the sliding hook 8.

[0026] An elastic sheet 12 is fixedly connected to the front of the slider 11, and a second magnet 14 is fixedly connected to one side of the elastic sheet 12. A first magnet 5 is fixedly connected to the back of the second magnet 14, and the back of the first magnet 5 is fixedly connected to the front of the connecting plate 4. This can limit the position of the hook 8 after it slides, so that the position of the packaging bag after it is stretched is limited, thereby facilitating the stretching and opening of packaging bags of different lengths.

[0027] The shape and size of the hook 8 match the shape and size of the main body 3 of the packaging bag, and one end of the hook 8 passes through the main body 3 of the packaging bag.
