[0041] It should be noted that, for ease of understanding and description, the front and rear directions are Figure 5 It should be understood that this orientation setting is only for the convenience of description and understanding and cannot be understood as a limitation of the present invention; the above-mentioned detachable connection can be connected by bolts or pins, and the movable connection can be connected by pins.

[0042] Specifically, the connecting rod 26 is in a "T"-shaped structure, and bolt or pin mounting holes are provided at the front and rear ends thereof.

[0043] Specifically, the rear end of the second connecting rod 31 is in a "U"-shaped structure, where the "U"-shaped structure can be movably connected to the front end of the first connecting rod 26 by a pin shaft, and the front end of the second connecting rod 31 is provided with an arc-shaped connector.

[0044] Specifically, the rear end of the connecting rod three 30 also presents a "U"-shaped structure, where the "U"-shaped structure can be movably connected to the arc-shaped connecting head at the front end of the connecting rod two 31 by a pin shaft. The front end of the connecting rod three 30 is provided with an arc-shaped connecting head, wherein the front end connecting head of the connecting rod three 30 is detachably connected to the inverted "T"-shaped support seat 29 by a pin shaft.

[0045] Reference Figure 5 The grab hook 28 adopts an arc-shaped structure, and its front end is a conical tip that can pierce the ton bag. A baffle 27 is provided at one end of the mounting plate 32 close to the grab hook 28, wherein the baffle 27 is provided with a slot corresponding to the grab hook 28. The width of the slot is slightly larger than the diameter of the grab hook, which can prevent the ton bag material from hanging on the grab hook when the grab hook retracts. The setting of the baffle can make the ton bag material on the grab hook fall off.

[0046] Reference Figure 1 and Figure 4 The bag breaking device 3 includes a tool moving frame 16 arranged at the rear end of the conveyor line frame 5, wherein the tool moving frame 16 is provided with a linear module 18 and a guide rail 17, the guide rail 17 is installed on both sides of the top of the tool moving frame 16, and a cross-shaped bag breaking knife 21 is also slidably connected to the guide rail 17, and a motion connecting plate 2 20 is arranged on one side of the cross-shaped bag breaking knife 21. The output end of the linear module 18 is connected to the motion connecting plate 2 20 through a motion connecting plate 1 19. The linear module 18 can drive the cross-shaped bag breaking knife 21 to move along the guide rail 17 toward the feeding port 8, and the linear module 18 can drive the cross-shaped bag breaking knife 21 to move between the bag grabbing assembly and the feeding port 8.

[0047] Furthermore, an accordion protective cover 22 is provided at the top of the guide rail 17 and directly above the feeding port 8. When the guide rail 17 moves to the position of the accordion anti-slip cover 22, the accordion anti-slip cover 22 can not only prevent the cross-shaped bag breaking knife 21 from slipping, but also prevent dust from adhering to the guide rail 17 during feeding, causing the slider to get stuck.

[0048] The specific operating principles of this application are as follows:

[0049] When in use, the main driving motor 6 generates power and transmits it to the driving roller 7 through components such as synchronous belts and gears (not shown in this article) to rotate, thereby realizing the transportation of the ton bag 4. The transmission line is independently composed of two long and short parts. The short part is in the bag breaking chamber. There is a gap between the driving rollers 7, so it will not affect the subsequent powder falling into the drop port 8;

[0050] When the ton bag 4 is transported to the designated position, the electric cylinder 11 rotates forward and drives the mounting plate 14 of the grab hook assembly to move up and down through the assembly of the guide rod 12 and the linear bearing 13 through the connecting piece. After it drops to the material hanging position, the four grab hook assemblies 15 evenly distributed around it are started, and the main driving cylinder 23 extends out. Through the transmission of connecting rod 1 26, connecting rod 2 31 and connecting rod 3 30, the grab hook 28 extends forward and is inserted into the ton bag, and the cylinder is locked; then the electric cylinder 11 starts to reverse and lifts the ton bag to the starting height of the bag breaking, and the moving connecting plate 19 and the linear module 18 are directly connected. The linear module 18 starts to rotate, driving the moving connecting plate 20 to move, and then driving the cross-shaped bag-breaking knife 21 to move along the guide rail 17 into the bag-breaking chamber. There are accordion protective covers 22 on both sides of the guide rail 17. In order to prevent the dust from adhering to the guide rail during feeding, causing the slider to get stuck, when the cross-shaped bag-breaking knife 21 moves to the bottom of the ton bag, the electric cylinder 11 rotates forward to move the ton bag 4 downward. When the bottom of the ton bag 4 hits the blade, a "cross"-shaped opening will be cut, and the opening will continue to open along the direction of the blade, causing the powder to fall out and fall into the drop opening 8 below;

[0051] In order to prevent the powder from remaining inside the ton bag 4, the electric cylinder 11 must move up and down slowly at regular intervals, continuously stretching and compressing the ton bag 4, so that the remaining powder continues to fall below. When the falling of the material is completed, the main driving cylinder 23 retracts and pulls the grab hook 28 out of the ton bag. In order to prevent incomplete unhooking, a baffle 27 is added. The width of the slot on it is slightly larger than the diameter of the grab hook 28, which can prevent the ton bag material from hanging on the grab hook 28 and causing it to fall.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
