[0021] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0022] To address the problems raised in the background art, this utility model provides a feeding station capable of automatically cutting open ton bags, including an AGV trolley 1 and a bag-cutting station 3. The AGV trolley 1 is responsible for transporting ton bags 2 to the bag-cutting station 3. One side of the bag-cutting station 3 has a roller shutter door 34. After the AGV trolley 1 transports the ton bag 2 to the roller shutter door 34, it opens the roller shutter door 34 and places the ton bag 2 into the bag-cutting station 3. Figure 1 The bag-cutting station 3 shown is an enclosed space, consisting of a top plate 31, a front plate 32, a left side plate 33, a roller shutter door 34, and a rear plate 35. A dust removal device 36 is installed on the outside of the rear plate 35. This device removes dust raised inside the bag-cutting station 3, preventing dust from spreading into the environment when the roller shutter door 34 is opened. The bag-cutting station 3 is equipped with roller guide rail 1 37 and roller guide rail 2 38. Roller guide rail 1 37 is located inside the front plate 32, and roller guide rail 2 38 is located inside the rear plate 35. Figure 2 As shown, for the convenience of describing the various structures inside the bag-cutting station 3, the top plate 31, the front plate 32, and the left side plate 33 have been omitted.

[0023] The enclosed space inside the bag-cutting station 3 is equipped with a lifting mechanism 4 and a bag-grabbing mechanism 5. Ton bags 2 are transferred to the bag-grabbing mechanism 5 via the lifting mechanism 4. After grabbing the ton bag 2, the bag-grabbing mechanism 5 moves along roller guide rail 1 37 and roller guide rail 2 38. The bag-grabbing mechanism 5 includes a sliding frame 51, which is connected to a lifting frame 53 via a fixed plate 52. The lifting frame 53 includes a gripper cylinder 1 532, a gripper cylinder 2 533, a gripper 1 534, and a gripper 2 535. Gripper 1 534 is rotatably connected to the output end of gripper cylinder 1 532, and gripper 2 535 is rotatably connected to the output end of gripper cylinder 2 533. The gripper cylinder 1 532, gripper 2 535, and gripper 2 535 are also connected to the output end of gripper cylinder 2 533. Cylinder 533 is connected to support frame 536 via cylinder seat 537 below it; support frame 536 has two crossbeams 538 in the middle, and cylinder seat 537 is set on crossbeams 538; lifting frame 53 has guide posts 531 at each of its four corners, and guide posts 531 pass through fixing plate 52 and are connected to support frame 536; the projected area of ​​support frame 536 is inside sliding frame 51, the projected area of ​​lifting frame 53 is inside support frame 536, lifting frame 53 is connected to the output end of lifting cylinder 55 via connecting plate 54, the cylinder body of lifting cylinder 55 is fixed on gantry frame 56, and both ends of gantry frame 56 are fixed on sliding frame 51. After the lifting cylinder 55 grasps the ton bag 2 with the gripper 1 534 and gripper 2 535, it can lift the ton bag 2. During this process, the four corners of the lifting frame 53 move upward along the guide column 531. After the bag gripping mechanism 5 stably grasps the ton bag 2, it needs to move towards the rear hopper 9. During the movement, the bottom sides of the sliding frame 51 are slidably connected to the roller guide rail 1 37 and roller guide rail 2 38 through multiple rollers 511. A connecting sliding plate 6 is provided on the side of the sliding frame 51 opposite to the rollers 511. The bottom end of the connecting sliding plate 6 is connected to the sliding frame 51, and the other end of the connecting sliding plate 6 is bent and fastened to the synchronous belt mechanism 7. During the transmission process, the synchronous belt mechanism 7 drives the connecting sliding plate 6 to move towards the hopper 9, and then the sliding frame 51 moves towards the hopper 9 along the roller guide rail 1 37 and roller guide rail 2 38. Cutters 91 and 92 are located above the hopper 9. Cutters 91 and 92 are rotatably connected to the hopper 9 and rotate in opposite directions. After the bottom of the ton bag 2 is cut open by cutters 91 and 92, the material falls into the hopper 9. The rear end of the hopper 9 is provided with a waste bag output chamber 10, which is used to hold empty ton bags.

[0024] Roller guide rail 1 37 and roller guide rail 2 38 are parallel to the length direction of synchronous belt mechanism 7. Synchronous belt mechanism 7 includes drive motor 71, drive shaft 73, and driven shaft 74. Drive shaft 73 and driven shaft 74 are arranged perpendicular to roller guide rail 1 37. Synchronous pulley 72, drive pulley 1 731, and drive pulley 2 732 are provided on drive shaft 73. The output end of drive motor 71 is connected to synchronous pulley 72 through a belt pulley, and drive motor 71 drives synchronous pulley 72 to rotate. Driven shaft 74 is provided with driven pulley 1 741 and driven pulley 2 742. Drive pulley 1 731 and driven pulley 1 741 are connected by a synchronous belt pulley. Belt 75 is connected; drive wheel 732 and driven wheel 742 are connected by synchronous belt 76. When synchronous belt 72 rotates, drive wheel 731 and drive wheel 732 rotate synchronously. The rotation of drive wheel 731 and drive wheel 732 drives synchronous belt 75 and synchronous belt 76 to rotate, thereby driving driven wheel 741 and driven wheel 742. Both synchronous belt 75 and synchronous belt 76 are connected to sliding frame 51 through connecting sliding plate 6. The movement of synchronous belt 75 and synchronous belt 76 pulls sliding frame 51 to move towards hopper 9, thereby moving bag grabbing mechanism 5 towards hopper 9.

[0025] The bag-grabbing mechanism 5, the connecting sliding plate 6, and the synchronous belt mechanism 7 solve the problem of grabbing and moving the ton bag 2. The lifting mechanism 4 is responsible for receiving the ton bag 2 transported by the AGV trolley 1. The lifting mechanism 4 includes a lifting base 41, which is fixed. A lifting plate 42 is slidably mounted on the lifting base 41. A frame 43 is provided around the upper periphery of the lifting plate 42. The frame 43 is connected to the output end of the lifting cylinder 44. The cylinder body of the lifting cylinder 44 is fixed on the lifting base 41. When the lifting cylinder 44 extends, it pushes the frame 43 to move upward. There are sliding rods at the four corners of the frame 43. The four corners of the lifting base 41 are provided with sliding rod sleeves corresponding to the sliding rods. The sliding rods are sleeved in the sliding rod sleeves to realize the sliding of the frame 43 relative to the lifting base 41. When the lifting cylinder 44 retracts, it pulls the frame 43 to move downward. Lifting cylinders 44 are provided on both sides of the lifting base 41.

[0026] In use, the ton bag 2 is placed on the ton bag pallet 21 of the AGV trolley 1. The AGV trolley 1 transports the ton bag pallet 21 and the ton bag 2 to one side of the roller shutter door 34 of the bag cutting station 3 and opens the roller shutter door 34. Then, the ton bag pallet 21 and the ton bag 2 are placed together on the lifting plate 42 of the lifting mechanism 4. Since there are two ton bags 2, the upper ton bag 2 is grabbed by the bag grabbing mechanism 5. The process is that the first gripper cylinder 532 and the second gripper cylinder 533 retract simultaneously, and the first gripper 534 and the second gripper 535 move closer together to clamp the ton bag 2. Then, the lifting cylinder 55 retracts, driving the lifting frame 53 and the ton bag 2 to move upward to the set height. Then, the drive motor 71 starts. The synchronous belts 75 and 76 move, pulling the bag-grabbing mechanism 5 forward via the connecting sliding plate 6. When the ton bag 2 reaches above the hopper 9, its bottom contacts the cutters 91 and 92. As the ton bag 2 moves forward, the cutters 91 and 92 completely cut open the bottom of the bag, rotating as it moves. Finally, the material falls into the hopper 9, and the synchronous belt mechanism 7 continues forward with the empty ton bag 2 to above the waste bag output hopper 10. The gripper cylinders 532 and 533 simultaneously extend to release the empty bag, which falls into the waste bag output hopper 10. When loading the lower ton bag, the lifting mechanism 4 is activated. The lifting cylinder 44 extends, lifting the frame 43 upwards, and the lifting plate 42 raises the lower ton bag to a designated position. This process is then repeated. Before loading again, the lifting cylinder 44 retracts back to its initial state.

[0027] This utility model's feeding station uses an AGV trolley 1 to deliver ton bags 2 to a bag-cutting station 3. The bag-grabbing mechanism 5 grabs the bag and lifts it to a predetermined position. Then, a synchronous belt mechanism 7 drives the bag-grabbing mechanism 5 forward. During this forward movement, the bottom of the ton bag 2 contacts cutters 91 and 92, cutting open the bottom of the ton bag 2 and allowing the material to fall into the hopper 9. After the material has fallen, the bag-grabbing mechanism 5 activates, and the empty bag falls into the waste bag output hopper 10, where it is output by a screw conveyor. The entire cutting and feeding process requires no manual operation, avoiding harm to the human body from toxic materials. Furthermore, the bag-cutting station 3 forms a closed space, contributing to a safe working environment. This reduces harm to personnel during the feeding process, achieves a fully automated feeding system, lowers labor costs, and protects the health of operators.

[0028] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
