[0057] Here’s how it works:

[0058] Prepare bags: put the heavy bag on the top of the placement table 27, the second driving member 29 works, drives the pushing member 28 to move, pushes the heavy bag to the top of the support plate 26, and then the second driving member 29 brings the pushing member 28 back to its original position, and then piles the heavy bags on the top of the placement table 27 for standby; the third driving member 252 works and contracts, so that the support arm 251 rotates and moves the first adsorption device 253 downward, contacts the heavy bag placed on the top of the support plate 26, and adsorbs it, then the third driving member 252 extends, so that the support arm 251 reverses, moves the first adsorption device 253 upward, lifts one end of the heavy bag, and at the same time drives the motor 211 to drive the sprocket 22 rotates, so that the chain 23 drives the support 24 to move, until the support 24 shovels the heavy bag with the end lifted up to the top of itself and holds it, the first adsorption device 253 releases the heavy bag, and the support 24 continues to move to transport the heavy bag to the receiving platform 2101 of the buffer 210; the fourth driving member 2103 drives the second adsorption device 2104 to move down, so that it contacts with the top of the heavy bag and adsorbs it, and at the same time the third adsorption device 2105 sucks the bottom of the packaging bag, and then the fourth driving member 2103 drives the second adsorption device 2104 to move up, lift the top of one end of the heavy bag away from the mounting frame 21, and open the bag mouth of the heavy bag;

[0059] Loading the bag: the sixth driving member 63 drives the first rotating shaft 62 to rotate, and moves the swing arm 66 and the clamp 68, and moves the two clamps 68 to the left and right sides of the heavy bag on the receiving platform 2101 respectively, and then the seventh driving member 69 works to drive the rotating block 610 to rotate, so that the two connecting rods 67 move, and move the two swing arms 66 to the support frame 64 until the clamp 68 can clamp the heavy bag, and then the clamp 68 clamps the two sides of the heavy bag, and at the same time, after the bag support assembly 65 is inserted into the bag opening of the heavy bag, the sixth driving member 63 drives the first rotating shaft 62 to rotate again (reverse rotation), so that the swing arm 66 moves the heavy bag to the bag clamping and unloading mechanism 7, and after the bag clamping and unloading mechanism 7 fixes the heavy bag, the bag support assembly 65 is reset, and the clamp 68 also loosens the heavy bag, and the sixth driving member 63 drives the first rotating shaft 62 to rotate and reset;

[0060] Loading: The material (such as granular material, powdered material) in the unloading mechanism 3 enters the heavy bag through the bag clamping unloading mechanism 7 for loading. After the loading of the quantitative material is completed, the unloading mechanism 3 stops unloading;

[0061] Bag unloading: The tenth driving member 83 drives the second rotating shaft 82 to rotate, so that the mounting arm 84, the mounting frame 85 and the clamping jaws 88 move together, and the two clamping jaws 88 are respectively moved to the two sides of the heavy bag (the clamping jaws 88 are opened during the movement of the second rotating shaft 82), and then the clamping jaws 88 are closed to clamp the two sides of the heavy bag, and then the bag clamping and unloading mechanism 7 releases the heavy bag, and the electric push rod 87 works to move the clamping jaws 88 downward, and at the same time, the second rotating shaft 82 is driven to rotate by the tenth driving member 83, so that after the heavy bag is placed on the transmission mechanism 4, the clamping jaws 88 release the packaging bag, and the second rotating shaft 82, the mounting arm 84, the clamping jaws 88 and other components are reset;

[0062] Packaging: After the conveying mechanism 4 conveys the heavy bag to the bag sewing mechanism 5 for sealing, the heavy bag is conveyed away and the operation is repeated to unload and package the materials.

[0063] It should be noted that a photoelectric switch is provided on the first mounting seat 61; when the first rotating shaft 62 rotates and moves the swing arm 66 to clamp the heavy bag, the photoelectric switch detects that the swing arm 66 has reached the predetermined position, and controls the seventh driving member 69, the clamp 68 and the bag-holding assembly 65 to start, ensuring that the heavy bag is clamped in the correct position, and the bag-holding assembly 65 is accurately inserted into the bag mouth of the heavy bag, thereby reducing operational errors and improving packaging accuracy; the operations of the above-mentioned devices are uniformly controlled by the PLC controller, which belongs to the prior art and is not described in detail here.

After the heavy bag falls on the receiving platform 2101, the heavy bag contacts with the pressure roller 2108 and the guide roller 2106, and the pressure roller 2108 and the guide roller 2106 rotate to guide the heavy bag to ensure that the heavy bag completely enters the top of the receiving platform 2101.
