The existing flapping device is not convenient to adjust the flapping range. Utility Model Content

[0028] Reference Figure 1 A bag-beating device is used in the field of packaging machines, comprising: a vertical plate 1, a horizontal plate 2, a beating plate 3, a driving component and an adjusting component.

[0029] The vertical plate 1 serves as the supporting structure of the entire device, and a horizontal plate 2 is fixedly provided on the top of one side thereof. A beating plate 3 is provided above the horizontal plate 2. The beating plate 3 is mainly used for beating the packaging bag to ensure that the material in the packaging bag can be evenly distributed or to discharge excess gas in the bag.

[0030] Reference Figure 4 A side plate 5 is fixedly provided at both ends of one side of the vertical plate 1, a round rod 10 is fixedly provided between the two side plates 5, a cylinder 9 is rotatably sleeved on the outer wall of the round rod 10, a connecting plate 23 is fixedly provided on the outer wall of the cylinder 9, a slide plate 21 is rotatably provided on the other end of the connecting plate 23, and an opening 24 is provided on the surface of the horizontal plate 2, the other end of the slide plate 21 is rotatably provided on the bottom of the flapping plate 3 through the opening 24, so that when the cylinder 9 rotates repeatedly, the flapping plate 3 can be driven to perform vertical reciprocating motion through the linkage action of the connecting plate 23 and the slide plate 21.

[0031] Reference Figure 2 A No. 3 ring 14 is fixedly sleeved on the outer wall of the rotatable rotating shaft 15, one end of the adjusting rod 13 is fixedly sleeved on the outer wall of the No. 3 ring 14, and the other end is fixedly sleeved on the No. 2 ring 12, one end of the outer wall of the telescopic rod 11 is rotatably set on the inner wall of the No. 2 ring 12, and the other end is fixedly sleeved on the No. 1 ring 8, the inner wall of the No. 1 ring 8 is sleeved with a connecting rod 7, and both ends of the outer wall of the connecting rod 7 are fixedly sleeved with connecting strips 6, and the other ends of the two connecting strips 6 are fixedly sleeved on the outer wall of the cylinder 9.

[0032] Specifically, the rotating shaft 15 drives the No. 3 ring 14 to rotate, the No. 3 ring 14 drives the No. 2 ring 12 to rotate through the adjusting rod 13, and the No. 2 ring 12 drives the No. 1 ring 8 to rotate through the telescopic rod 11. Since the connecting rod 7 can rotate along the cylinder 9, and the No. 1 ring 8 is sleeved on the outer wall of the connecting rod 7, the rotation of the No. 1 ring 8 will drive the connecting rod 7 to swing up and down reciprocatingly, thereby driving the cylinder 9 to rotate reciprocatingly, and finally realizing the reciprocating up and down movement of the flapping plate 3, realizing the flapping of the bottom end of the packaging bag, and realizing the bag flapping step.

[0033] refer to Figure 2-3The adjusting rod 13 includes a circular plate 16, a threaded rod 17 and a threaded cylinder 18. The circular plate 16 is fixedly arranged on the outer wall of the No. 3 ring 14, the threaded rod 17 is rotatably arranged at one end of the circular plate 16, one end of the threaded cylinder 18 is fixedly arranged on the outer wall of the No. 2 ring 12, and is threadedly sleeved on the outer wall of the threaded rod 17; the telescopic rod 11 includes an outer cylinder 19 and an inner rod 20. One end of the outer wall of the outer cylinder 19 is rotatably arranged on the inner wall of the No. 2 ring 12, one end of the inner rod 20 is fixedly arranged on the outer wall of the No. 1 ring 8, and the outer cylinder 19 is sleeved on the outer wall of the inner rod 20.

[0034] Specifically, when the size of the packaging bag needs to be changed and the range of the vertical displacement of the flapping plate 3 needs to be adjusted, the threaded rod 17 is rotated to move the threaded cylinder 18, thereby adjusting the length of the adjusting rod 13. The extension or shortening of the adjusting rod 13 will change the swing range of the connecting rod 7, thereby adjusting the vertical displacement range of the flapping plate 3. Since the telescopic rod 11 can be extended and retracted, it can adapt to the distance between the adjusting rod 13 and the connecting rod 7, thereby ensuring normal driving.
