When in use, the position of the blade 35 is adjusted by the slide 31, thereby adjusting the cutting position of the ton bag; when cutting, as the ton bag is conveyed, the ton bag forces the rotating arm 33 to rotate and compress the elastic member 34. Under the rebound force of the elastic member 34, the blade 35 always contacts the bottom of the ton bag, and the blade 35 starts cutting from the position of the horizontal center line of the ton bag; when the ton bag is away from the cutter, the rotating arm 33 is reset under the action of the elastic member 34. In one embodiment, there are two cutting knife mechanisms 30, and the two cutting knife mechanisms 30 are staggered and installed on both sides of the chassis 11, and the two blades 35 are at the same height; optionally, the centers of the two blades 35 intersect at the center of the ton bag; three of the four faces of the ton bag are cut by the two blades 35.

[0053] like Figure 2 and Fig.10 As shown, the material shaking mechanism 40 is installed in the chassis 11, and the material shaking mechanism 40 is set corresponding to the hopper 13, and the material shaking mechanism 40 is used to beat the ton bag. The material shaking mechanism 40 includes a main shaft 41, a material shaking arm 42, a material shaking rod 43 and a material shaking power element 44. The main shaft 41 is pivoted to the chassis 11, the main shaft 41 is located above the hopper 13, the material shaking arm 42 is installed on the main shaft 41, the material shaking rod 43 is installed on the material shaking arm 42, and the material shaking power element 44 is used to drive the main shaft 41 to rotate; optionally, there are two material shaking arms 42 and two material shaking rods 43, and the two ends of the material shaking rod 43 are respectively connected to the two material shaking arms 42.

[0054] like Figure 1 and Fig.11As shown, in order to realize automatic feeding, the fully automatic ton bag breaking machine 100 also includes a conveying mechanism 50 and a lifting mechanism 60. The conveying mechanism 50 includes a roller and an anti-skid belt, and the ton bag is conveyed by the anti-skid belt, which is a prior art; the lifting mechanism 60 includes a fixed frame 61, a platform 62, a position sensor (not shown) and a feeding assembly 63. The platform 62 is slidably mounted on the fixed frame 61 through a motor, a chain and a sprocket. The position sensor is installed on the fixed frame 61, and the position sensor is used to sense the horizontal position of the ton bag. The feeding assembly 63 includes a base 631, a carrying frame 632, a conveyor belt 633, a top frame (not marked in the figure), a support plate 634, a lifting power element (not marked in the figure) and a lateral moving power element (not marked in the figure). Optionally, the base 631 is installed on the platform 62, there are multiple conveyor belts 633, and each conveyor belt 633 is installed at intervals on the carrying frame 632; the top frame is arranged below the carrying frame 632, the lifting power element is installed on the base 631, and the lifting power element is used to drive the top frame to approach or move away from the carrying frame 632; there are multiple support plates 634, each support plate 634 is staggered with the conveyor belt 633, the lateral moving power element is installed on the top frame, and the lateral moving power element It is used to drive the pallet 634 to slide on the top frame to adjust the position of the ton bag; further, the pallet 634 is divided into two groups, the two groups of pallets 634 correspond to the two ends of the bearing frame 632 respectively, there are two transverse force elements, the two transverse force elements correspond to the two groups of pallets 634 respectively, and the two groups of pallets 634 are driven to move in the same direction or in the opposite direction through the sprocket and the chain; when in use, the position of the ton bag is sensed by the position sensor, if it is found that it is not centered, the top frame drives the pallet 634 to rise and be higher than the conveyor belt 633, and then the two groups of pallets 634 move in the same direction or in the opposite direction, cooperate with the position sensor, so that the ton bag is centered, which is convenient for the gripper assembly 23 to take the material. The lifting mechanism 60 also includes a closed door 64, which is slidably arranged on the fixed frame 61. When in use, the forklift places the ton bag on the conveying mechanism 50, and the conveying mechanism 50 feeds the material toward the feeding assembly 63, or the forklift places the ton bag directly on the feeding assembly 63 from the side adjacent to the conveying mechanism 50, thereby realizing two-way access and multiple conveying docking methods.

[0055] When in use, a forklift or unloading mechanism places the ton bag on the conveying mechanism 50, and the conveying mechanism 50 feeds the material toward the feeding assembly 63. Alternatively, a forklift or unloading mechanism places the ton bag directly on the feeding assembly 63, and the platform 62 is then lifted to the loading station, and the conveyor belt 633 then conveys the ton bag to the first conveyor belt; during the lifting process, if the ton bag is not in the center of the conveying forward direction, the ton bag is centered through the cooperation of the position sensor and the pallet 634.

[0056] Next, after the first conveyor belt conveys the ton bag to the bag grabbing station, the first conveyor belt stops operating, and the transmission power element 221 drives the transmission shaft 222 to rotate. Under the action of the pulley group 223 and the auxiliary wheel group 224, the clamping claw assembly 23 moves to the bag grabbing station. Then, the lifting power element 216 drives the bracket 215 to descend until the pressure plate abuts against the top of the ton bag. The first pick-up and placement power element 238 drives the first connecting rod 235 to move through the first connecting arm 236, thereby driving the first air pipe 231 to rotate. At the same time, the second pick-up and placement power element drives the second connecting rod 239 to move through the second connecting arm, thereby driving the second air pipe 232 to rotate synchronously in the opposite direction, so that the first cutter head 233 and the second cutter head 234 rotate synchronously in the opposite direction to achieve the clamping of the ton bag; when grabbing the bag, the first cutter head 233 and the second cutter head 234 blow air to prevent the air hole 2331 from being blocked by powder and to replenish air to the ton bag.

[0057] Then, the frame 211 drives the clamping jaw assembly 23 to move toward the hopper 13, and at the same time, the first conveyor belt is transmitted at the same speed as the frame 211; when passing through the cutting station, the blade 35 cuts the outer side of the bottom end of the ton bag, and, as the ton bag is conveyed, the ton bag forces the rotating arm 33 to rotate, and under the action of the two slices, the three sides of the ton bag are cut open, leaving one side connected.

[0058] When the ton bag is transferred to the unloading station, the powder falls rapidly from the ton bag to the hopper 13 under the action of gravity. At the same time, the first blade 233 and the second blade 234 continue to blow air to keep the ton bag in a certain inflated state, so that after most of the material is lost, the ton bag will not collapse and wrinkle too much to hide the material, so as to clean the material and improve the emptying rate; moreover, the air duct 219 is ventilated to prevent the dust after the bag is cut from entering the frame 211 and being difficult to clean. Since the ton bag retains one side of the connection and will not completely fall off and fall into the hopper 13, when the ton bag passes through the shaking mechanism 40, the shaking power element 44 drives the shaking rod 43 to continuously beat the ton bag back and forth. The bottom of the ton bag passes over the shaking mechanism 40 during the continuous beating process, so that the bottom of the ton bag is dragged out of the hopper 13 without being buried by the powder, thereby more thoroughly emptying the material; at this time, the vibrator vibrates to prevent the powder from accumulating in the hopper 13.

[0059] After unloading is completed, as the frame 211 slides, the ton bag is transferred to the second conveyor belt. At this time, the first cutter head 233 and the second cutter head 234 are loosened, and the ton bag falls to the second conveyor belt and is transferred to the external collection mechanism via the second conveyor belt. During the back-and-forth sliding of the frame 211, the dust removal member 214 abuts against the top of the chassis 11, thereby removing the dust on the top of the chassis 11, and then discharging it through the first dust hopper 17. At the same time, the cleaning member 212 cleans the dust on the powder strip 14 to the dust collecting pipe 15 for discharge. This fully automatic ton bag breaking machine 100 realizes automated operation, can efficiently remove dust, and improves the emptying rate of ton bags.

[0060] The fully automatic ton bag breaking machine 100 of the present invention transfers the ton bag to the cutting station through the clamping claw assembly 23, the cutting knife mechanism 30 cuts the outside of the ton bag, the clamping claw assembly 23 then transfers the ton bag to the top of the hopper 13, and the shaking mechanism 40 beats the ton bag to reduce the material remaining in the ton bag and improve the emptying rate.
