[0033] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0034] like Figure 1 As shown, the powder bag opening machine described in the utility model includes a loading bin 100, a bag opening and taking bin 200, and a waste bag collection bin 300 which are connected in sequence. The material is sent to the bag opening and taking bin 200 through the loading bin 100. After the bag opening and taking bin 200 has finished taking the material, the waste bag is sent to the waste bag collection bin 300 for unified collection. The loading bin 100, the bag opening and taking bin 200, and the waste bag collection bin 300 are independent of each other and sealed and connected. A dust leakage monitoring module is provided in each bin to monitor the dust amount in each bin. The powder bag opening machine is also provided with a dust removal mechanism, which is connected to the loading bin 100, the bag opening and taking bin 200, and the waste bag collection bin 300 respectively, and can perform negative pressure dust removal on each bin.

[0035] like Figures 1 to 4As shown, a frame 1 is arranged in the bag opening and material taking bin 200, a lifting mechanism 2 is arranged at the lower part of the frame 1, a conveying mechanism 3 is arranged on the lifting mechanism 2, and the lifting mechanism 2 can drive the conveying mechanism 3 to rise and fall. A force sensor 4 is arranged between the bottom of the conveying mechanism 3 and the lifting mechanism 2, and the residual material in the material bag can be weighed by the force sensor 4, so as to monitor the residual amount of the material, ensure that the material is sucked as much as possible, and reduce the residual amount of the material.

[0036] A hopper assembly 5, a shaping mechanism 9, and a bag lifting mechanism 10 are arranged in the middle of the frame 1, and the shaping mechanism 9 and the bag lifting mechanism 10 are located above the hopper assembly 5. A cutting mechanism 7 and a material suction mechanism 8 are arranged above the hopper assembly 5 on the upper part of the frame 1.

[0037] like Figure 5 , Figure 6 As shown, the hopper assembly 5 is provided with a plurality of hopper plates 51, and a clearance channel 53 is provided on the hopper assembly 5, and the conveying mechanism 3 can pass through the clearance channel 53 when ascending or descending; Figure 5 As shown, during feeding, the conveying mechanism 3 rises to a high position, exceeding the position above the hopper plate 51; Figure 6 As shown, when taking materials, the conveying mechanism 3 descends to a low position and is located below the hopper plate 51. Several hopper plates 51 are connected to the vibration mechanism 6 through the connecting frame 52. The vibration mechanism 6 drives the hopper plates 51 to resonate through the connecting frame 52, making the material in the bag easier to absorb. The hopper assembly 5 and the vibration mechanism 6 constitute an auxiliary unloading mechanism. The vibration mechanism 6 transmits the exciting force through the hopper assembly 5, so that the material in the hopper assembly 5 follows the vibration, which is more conducive to the unloading of materials, facilitates the absorption of materials, and reduces the amount of residual materials. The central wall surface of the hopper assembly 5 is concave, and the side hopper wall is set with an inclination angle, which is inclined downward toward the central part. During vibration, the bag can be close to the side wall of the hopper so that the material can gather in the middle of the hopper during the vibration process.

[0038] like Figures 2 to 4 As shown, the shaping mechanism 9 includes a vertical lifting mechanism 91 and a shaping plate 92. The vertical lifting mechanism 91 can drive the shaping plate 92 to move up and down to loosen or tighten the material bag. While shaping the material bag, it can also prevent the material bag from moving during the cutting process to ensure the cutting effect.

[0039] like Figures 2 to 4 As shown, the bag lifting mechanism 10 includes a lever mechanism 101 and a horizontal moving mechanism 102. The lever mechanism 101 is connected to the horizontal moving mechanism 102. The horizontal moving mechanism 102 is connected to the shaping plate 92. When the bag is cut, the horizontal moving mechanism 102 drives the lever mechanism 101 to insert into the incision of the bag, and then retracts to lift the incision of the bag, so that the suction mechanism 8 can be inserted into the bag to suck the material.

[0040] like Figure 3 ,Figure 4 As shown in the figure, the cutting mechanism 7 includes an ultrasonic cutting knife 71 and a robot 72. The ultrasonic cutting knife 71 is arranged at the front end of the robot 72, and the robot 72 controls the ultrasonic cutting knife 71 to cut the material bag along a specified route (such as a U-shaped line). The ultrasonic cutting knife 71 melts the position where the tool contacts the material bag through the high-frequency vibration and high energy of ultrasonic waves, so as to achieve no burrs and debris at the cut during the cutting process. The robot 72 can be a four-axis robot or a six-axis robot. By controlling the ultrasonic cutting knife 71 with the robot 72, the cutting is more accurate and flexible.

[0041] As Figures 2 to 4 shown in the figure, the material suction mechanism 8 includes a material suction gun 81, a lifting module 82 and a transverse movement module 83. The material suction gun 81 is connected to the lifting module 82 and the transverse movement module 83. The lifting module 82 can drive the material suction gun 81 to move up and down in the Z direction (vertical direction), and the transverse movement module 83 can drive the material suction gun 81 to move left and right, forward and backward in the X and Y directions (horizontal direction). The material suction gun 81 moves in the XYZ three directions through the module, and the material suction is cleaner and more thorough, which is more conducive to reducing the residual amount of materials.

[0042] As Figure 1 shown in the figure, a bag pressing mechanism 11 and a waste bag collection frame 12 are arranged in the waste bag collection bin 300. The bag pressing mechanism 11 is located above the waste bag collection frame 12. After the waste bag is sent to the waste bag collection bin 300, the bag pressing mechanism 11 flattens the waste bag into the waste bag collection frame 12 for unified collection.

[0043] When the utility model is actually used, the material bag filled with materials is sent from the feeding bin 100 to the bag opening and material taking bin 200, and the conveying mechanism 3 conveys the material bag to directly above the hopper assembly 5. The lifting mechanism 2 drives the conveying mechanism 3 and the material bag to descend, and the material bag is put into the hopper assembly 5; after the shaping pressing plate 92 of the shaping mechanism 9 moves downward to flatten the material bag, the cutting mechanism 7 opens the material bag along a specified route and then returns to the original position. The bag lifting mechanism 10 extends and lifts the material bag, and then the material suction gun 81 of the material suction mechanism 8 extends into the material bag to suck the materials. During the material suction process, the vibration mechanism 6 drives the hopper assembly 5 to vibrate to assist in discharging materials; after the material suction is completed, the lifting mechanism 2 drives the conveying mechanism 3 to rise to push the empty material bag upward. The residual materials in the material bag are weighed through the force measuring sensor 4. If the weighing value is greater than the set value, it means that there is more residual amount in the material bag. The lifting mechanism 2 drives the conveying mechanism 3 and the material bag to descend into the hopper assembly 5 again, and repeats the vibration and material suction steps to suck the residual materials. If the weighing value is less than or equal to the set value, the material suction mechanism 8 returns, and the conveying mechanism 3 sends the empty material bag out to the waste bag collection bin 300, and the bag pressing mechanism 11 presses the waste bag into the waste bag collection frame 12. During the whole process, the dust removal mechanism works to extract the dust and foreign matters in the equipment, and at the same time, the dust leakage amount monitoring module monitors the dust content in the equipment in real time.

[0044] The above description is an explanation of the present utility model and not a limitation thereof. Without departing from the spirit of the present utility model, the present utility model may be modified in any form.
