The sewing mechanism 5 is located above the transmission mechanism 4. The sewing mechanism 5 refers to a device for sealing heavy bags, such as a hot press sealing machine.

[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 stacks the heavy bags on the top of the placement table 27 for standby; the third driving member 252 works and contracts, causing the support arm 251 to rotate and move the first adsorption device 253 downward, contacting the heavy bag placed on the top of the support plate 26, and adsorbing it, then the third driving member 252 extends, causing the support arm 251 to reverse, and move the first adsorption device 253 upward, so that one end of the heavy bag is lifted, and at the same time the drive motor 211 drives the sprocket 22 rotates, causing the chain 23 to drive the support 24 to move until the support 24 shovels the heavy bag with the raised end above itself and holds it, then the first suction device 253 releases the heavy bag, and the support 24 continues to move, transporting the heavy bag to the receiving platform 2101 of the buffer unit 210; the fourth driving member 2103 drives the second suction device 2104 to move downward, so that it contacts the top of the heavy bag and holds it, while the third suction device 2105 sucks the bottom of the packaging bag, and then the fourth driving member 2103 drives the second suction device 2104 to move upward, lifts the top of the end of the heavy bag away from the mounting frame 21, and opens 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. 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. Then the clamp 68 works to clamp the two sides of the heavy bag, and at the same time, after the bag-holding assembly 65 is inserted into the opened bag mouth 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. After the bag clamping and unloading mechanism 7 fixes the heavy bag, the bag-holding assembly 65 is reset, and the clamp 68 also releases the heavy bag. 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, causing the mounting arm 84, the mounting frame 85 and the clamping jaws 88 to 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). Then, the clamping jaws 88 close and clamp the two sides of the heavy bag. 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. At the same time, the second rotating shaft 82 is driven to rotate by the tenth driving member 83 to place the heavy bag on the conveying mechanism 4. After that, the clamping jaws 88 release the packaging bag, and the second rotating shaft 82, the mounting arm 84, the clamping jaws 88 and the other components are reset.

[0062] Packaging: The conveying mechanism 4 conveys the heavy bag to the sewing mechanism 5 for sealing, and then the heavy bag is conveyed away. The operation is repeated to unload and pack 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-stretching assembly 65 to start, ensuring that the heavy bag is clamped in the correct position, and the bag-stretching 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 all uniformly controlled by the PLC controller, which belongs to the existing technology and is not described in detail here.

After the heavy bag falls on the receiving platform 2101, the heavy bag contacts 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. The pressure plate 21010 is used to limit the heavy bag to ensure that the heavy bag contacts the pressure roller 2108 and the guide roller 2106.

[0065] In this embodiment, as a further optimization solution, please refer to Figure 11 and Figure 14 The clamp 68 includes two gears 681, two clamping blocks 682 and a ninth driving member 683 (electric telescopic rod).

The fixed end of the ninth driving member 683 is hinged to the swing arm 66, and the movable end of the ninth driving member 683 is hinged to a clamping block 682; when the ninth driving member 683 drives a clamping block 682 to rotate, it will cause the gear 681 on the clamping block 682 to rotate. Since the two gears 681 are engaged, the other gear 681 will also rotate, causing the two clamping blocks 682 to move closer or farther away synchronously.

[0066] In this embodiment, as a further optimization solution, please refer to Figure 13The bag-holding assembly 65 includes a rotating rod 652, an eighth driving member 651 (electric telescopic rod), and two bag-holding plates 653 (similar to L-shaped plates); the rotating rod 652 is rotatably arranged on the support frame 64, the fixed end of the eighth driving member 651 is hinged on the support frame 64, the movable end of the eighth driving member 651 is hinged to the rotating rod 652, and the two bag-holding plates 653 are respectively arranged on the outer wall of the rotating rod 652; the eighth driving member 651 is extended and retracted, so that the rotating rod 652 rotates and moves with the two bag-holding plates 653. When the end of the bag-holding plate 653 is inserted into the bag opening of the heavy bag, the bag opening of the heavy bag will be opened.

[0067] In this embodiment, as a further optimization solution, please refer to Figure 15 and Figure 16 , a linkage rod 86 is hinged on the mounting frame 85, and the linkage rod 86 is parallel to the mounting arm 84.
