[0021] like Figure 1 , Figure 2As shown, a non-breakable rice husk bag unpacking machine includes a robot arm 1, a robot grasping mechanism 2, a rice husk suction and stripping device 3, and a collecting bucket 4. The robot arm 1 is connected to the robot grasping mechanism 2. The robot grasping mechanism 2 is provided with spike teeth 2-1 and a negative pressure suction cup 2-3. The spike teeth 2-1 can be inserted into the bottom of the rice husk bag 5 to grasp the rice husk bag 5 upwards through the squeezing friction between the rice husks, and transfer it to the top of the rice husk suction and stripping device 3. The collecting bucket 4 is arranged below the rice husk suction and stripping device 4.

[0022] The manipulator grasping mechanism 2 includes spike teeth 2-1, a retracting mechanism 2-3, a negative pressure suction cup 2-2, an air duct 2-7, and a fan 2-6. A plurality of the spike teeth 2-1 are fixed on the lower bottom surface of the retracting mechanism 2-3. The negative pressure suction cup 2-2 is connected to the bottom of the retracting mechanism 2-3. The spike teeth 2-1 pass through the through holes 2-4 on the negative pressure suction cup 2-2. The retracting mechanism 2-3 can drive the negative pressure suction cup 2-2 to move up and down. One end of the air duct is connected to the fan, and the other end of the air duct 2-7 is connected to the bottom of the retracting mechanism 2-3.

[0023] The retraction mechanism 2-3 includes a guide rod 2-33, a guide sleeve 2-32, a cylinder 2-31, and a carrier 2-34. The cylinder body of the cylinder 2-31 is fixedly connected to the carrier, the driving end of the cylinder 2-31 is fixedly connected to the negative pressure suction cup 2-2 at the bottom of the carrier 2-34, the guide sleeve 2-32 is fixed to the upper end of the carrier 2-34, the guide rod 2-33 is in the guide sleeve 2-32 and is slidably connected to the guide sleeve 2-32, the lower end of the guide rod 2-33 is fixedly connected to the negative pressure suction cup 2-2, and the plurality of spike teeth 2-1 are fixed to the bottom plane of the carrier 2-34.

[0024] The diameter of the through hole 2-4 on the negative pressure suction cup 2-2 is 3 to 5 times the diameter of the spike tooth 2-1.

[0025] It also includes a bag dust collector 2-6, which is connected to the fan 2-5.

[0026] The rice husk suction stripping device 3 includes a rotating cutting head 3-1, a hollow tube 3-5, a negative pressure suction device 3-2, and a gas-solid separator 3-3. The rotating cutting head 3-1 is installed at the upper end of the hollow tube 3-5, the hollow tube 3-5 is connected to the negative pressure suction device 3-2, and the gas-solid separator 3-3 is also connected to the negative pressure suction device 3-2. The negative pressure suction device 3-2 can also use a fan, and the gas-solid separator 3-3 can use a bag dust collector or a simple bag to collect the rice husk sucked out of the hollow tube 3-5 by negative pressure. The rotating cutting head 3-1 is set at the upper end of the hollow tube 3-5, and the driving rotating motor is at the bottom of the hollow tube 3-5. The rotating shaft connecting the rotating cutting head 3-1 and the motor is connected in the hollow tube 3-5, and the rotating shaft and the hollow tube 3-5 are positioned by bearings and brackets.

[0027] A limit switch 3 - 4 is provided in the space above the rice husk suction and stripping device 3 .

[0028] The unbreakable rice husk bag unpacking machine comprises a mechanical arm 1, a mechanical gripping mechanism 2, a rice husk suction stripping device 3, and a collecting bucket 4. The mechanical arm 1 drives the mechanical gripping mechanism 2 to grab the bottom of the rice husk bag upwards, and the rice husk suction stripping device 3 cuts and sucks a part of the rice husk into the gas-solid separator 3-3, and the remaining rice husk falls into the collecting bucket 4 due to its own collapse. The empty rice husk bag is unloaded to the empty bag area by the mechanical arm 1 driving the mechanical gripping mechanism 2, so as to realize the function of unpacking without breaking the bag.

[0029] The robot gripping mechanism 2 is a spike 2-1 + negative pressure suction cup 2-2 type. The spike 2-1 of the robot gripping mechanism 2 is a straight tooth. By inserting the plastic packaging bag, the rice husk bag is lifted by friction. When unloading, the retraction mechanism 2-3 of the spike 2-1 is used to complete the unloading action. The negative pressure suction cup 2-2 of the robot gripping mechanism 2 generates negative pressure through the fan 2-5 and the pipeline 2-6. When the rice husk collapses and falls into the collection bucket, the rice husk bag can still be sucked by the negative pressure suction cup 2-2.

[0030] See Figure 2The negative pressure suction cup 2-2 has a plurality of small through holes 2-4, the aperture of which is about 3 to 5 times the diameter of the spike teeth. A cylinder 2-31 is connected to the middle of the negative pressure suction cup 2-2, and guide rods 2-33 are arranged at the four corners. The cylinder 2-31 drives the negative pressure suction cup 2-2 to move up and down to remove the rice husk packaging bag from the spike teeth 2-1. The main bearing body 2-34 of the retracting mechanism 2-3 is a square box without a bottom, the top of which is connected to the air duct 2-7, and the back of the air duct 2-7 is connected to the fan 2-5 to provide negative pressure, which is used to suck the rice husk packaging bag to prevent the packaging bag from being severely deformed after the rice husk bag is removed. The nail teeth 2-1 are welded on the lower bottom surface of the inner side of the carrier 2-34 of the retracting mechanism 2-3, and the outer dimension of the negative pressure suction cup 2-2 is 5-6 mm smaller than the inner dimension of the carrier 2-34 of the retracting mechanism 2-3, and the outer dimension of the negative pressure suction cup 2-2 is 4-5 mm larger than the bottom dimension of the rice husk bag 5. The bottom of the rice husk bag 5 can be installed in the retracting mechanism 2-3 box (carrier 2-34), which will be more stable. At this time, the cylinder 2-31 shrinks to the shortest, and the negative pressure suction cup 2-2 enters the inside of the box (carrier 2-34). The negative pressure system is turned on, and air is sucked into the pipeline from the small through hole 2-4 on the negative pressure suction cup 2-2. When the air in the box is smaller than the outside of the box, negative pressure is formed. Since there is also a gap on the side of the box, when negative pressure is formed, the bag will be evenly expanded, so that the rice husk is looser and easy to fall off.

[0031] In the rice husk suction stripping device 3, a rotating cutting head 3-1 is provided at the end of the hollow tube 3-5, and a negative pressure suction device 3-2 and a gas-solid separator 3-3 are connected to the bottom of the tube. A limit switch 3-4 is provided between the rice husk suction stripping device 3 and the spike teeth 2-1 to prevent the rotating cutting head 3-1 from contacting the spike teeth 2-1. The rice husk suction stripping device 3 is located above the center of the collecting bucket 4.

[0032] A bag unpacking process of a non-breakable rice husk bag unpacking machine, comprising: grabbing the bottom of the rice husk bag upwards through the manipulator grasping mechanism 2, and aligning the opening of the rice husk bag downwards to the rice husk suction and stripping device 3, the rotating cutting head 3-1 of the rice husk suction and stripping device 3 rotates at a speed of 30 to 60 r / min to cut the rice husk, and the cut rice husk is sucked by the negative pressure suction device 3-2 of the rice husk suction and stripping device 3, and is sucked into the gas-solid separator 3-3 through the hollow tube 3-5 for collection; when the spike teeth 2-1 descend to the same height as the lower end of the spike teeth, the trigger touches the limit switch , (this height is the lower limit height of the spike teeth), the manipulator grasping mechanism 2 is lifted vertically upward and separated from the rice husk suction and stripping device 3; at this time, the rice husk expands and shrinks due to the loss of part of the external support, and then the manipulator 1 begins to swing, shaking off the rice husk in the rice husk bag 5, and the fan 2-5 is always turned on to adsorb the rice husk bag 5 on the negative pressure suction cup 2-2; after shaking for 3s, the manipulator 1 drives the manipulator grasping mechanism 2 to unload the rice husk bag to the specified location, turns off the fan 2-5, and the cylinder 2-31 extends to strip the rice husk bag from the spike teeth 2-1, completing a working cycle.
