[0049] It should be noted that the ton bag breaking machine disclosed in the embodiment of the utility model also includes a controller, wherein the pressing plate device 400 and the cutting knife device 200 are both electrically connected to the controller.

[0050] First, the ton bag enters the ton bag breaking machine from the feeding device 100 and falls onto the flap device 300. At this time, the pressure plate device 400 is controlled to press the opening of the ton bag to fix the ton bag on the ton bag breaking machine, and then the cutting knife device 200 is controlled to break the ton bag. When the ton bag is broken, the flap device 300 flips over the preset angle and separates from the ton bag, and the material flows out of the ton bag and falls. The larger volume of the falling material is crushed into materials of preset volume by the crushing device 500 and then continues to fall.

Technical personnel in this field can make a choice according to actual needs.

[0072] The embodiment of the present utility model does not limit the specific structure of the crushing device 500. As long as the structure meets the use requirements of the present utility model, it is within the protection scope of the present utility model.

[0073] Please refer to Figure 7 As one embodiment, the crushing device 500 disclosed in the embodiment of the utility model includes a screen 501, a rotating shaft 502 and a blade 503, wherein there are multiple blades 503 and they are arranged along the circumference of the rotating shaft 502, the rotating shaft 502 is placed above the screen 501, and the screen 501 is provided with multiple sieve holes.

[0074] When the material falls onto the screen 501, the larger volume of material continues to fall through the screen holes, while the larger volume of material cannot pass through the screen holes. At this time, the crushing device 500 needs to be started, and the rotating shaft 502 of the crushing device 500 rotates, driving the blade 503 to rotate circumferentially, thereby crushing the material, so that the material is crushed into a preset volume of material to facilitate passing through the screen holes.

[0075] It should be noted that the ton bag breaking machine disclosed in the embodiment of the utility model further includes a third driving mechanism, which is connected to the rotating shaft 502 and can drive the rotating shaft 502 to rotate.

[0077] As a further embodiment, the ton bag breaking machine disclosed in the embodiment of the utility model also includes a material level meter 1100, wherein the material level meter 1100 is used to detect the material stacking height in the ton bag breaking machine. When the material stacking height reaches a preset height, the material level meter 1100 transmits a signal to a controller for controlling the ton bag breaking machine, so that the ton bag breaking machine stops running, thereby avoiding material accumulation problems caused by equipment failure or material agglomeration.

[0078] Please refer to Fig. 9 As a further embodiment, the ton bag breaking machine disclosed in the embodiment of the utility model also includes a waste bag processing device 800 and a waste bag collecting device 900.

At this time, the push rod 804 and the push plate 805 also move in a direction away from the waste bag processing mechanism under the action of the connecting member 802 and the movable plate 803; when the waste bag falls onto the push plate 805, the cylinder rod of the linear cylinder retracts, driving the connecting member 802 and the movable plate 803 to move in a direction close to the waste bag processing mechanism. At this time, the push rod 804 and the push plate 805 also move in a direction close to the waste bag processing mechanism under the action of the connecting member 802 and the movable plate 803, and push the waste bag into the waste bag processing mechanism.
