Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example: Reference Figure 1-6 The automatic bag-feeding packaging machine shown includes a conveying platform 1, a pushing platform 20, and a frame 4. The conveying platform 1 and the pushing platform 20 are connected, and the frame 4 is provided on one side of the pushing platform 20.

[0037] As one embodiment of this example, a notch for the conveyor belt 2 is provided in the middle of the conveyor platform 1. The conveyor belt 2 is driven by a motor and is provided with a separator plate 3 for separating packaging bags. In order to transfer the packaging bags to the pushing platform 20, a pushing mechanism for converting the packaging bag platform is provided on the frame 4.

[0038] As one embodiment of this invention, the stacking mechanism includes a reciprocating crossbeam 5 located directly above the pushing platform 20. The reciprocating crossbeam 5 is installed and fixed via an extension plate on the frame 4. A first cylinder 6 and a suction nozzle 8 for transferring packaging bags are provided on the end face of the reciprocating crossbeam 5. The first cylinder 6 is fixed to the end face of the reciprocating crossbeam 5 with bolts. A set of bag-lifting crossbeams 7 are provided at the telescopic end of the first cylinder 6. The bag-lifting crossbeams 7 are located above the conveying platform 1. At least two sets of suction nozzles 8 are provided on the outer wall of the bag-lifting crossbeams 7. The suction nozzles 8 can pick up the packaging bags located below them so that the gripping plate assembly can arrive and transfer the packaging bags to the pushing platform 20 via the gripping plate assembly.

[0039] The gripper assembly consists of two sets of guide wheels rotatably connected within a groove on the bottom surface of the reciprocating crossbeam 5. These guide wheels are connected by a synchronous belt. A primary motor 10 is mounted on the outer wall of the reciprocating crossbeam 5. The primary motor 10 drives the guide wheels to rotate, thus activating the synchronous belt. The activated synchronous belt drives a primary slider 9 to move on the reciprocating crossbeam 5, causing the hanger 14, mounted on the bottom surface of the primary slider 9, to reciprocate on the reciprocating crossbeam 5. The hanger 14 has a T-shaped cross-section and is fixedly mounted on its bottom surface. A set of fixed plates 11 is provided, and a set of movable gripping plates 12 is hinged to the bottom of the fixed plates 11. In order to allow the movable gripping plates 12 to be flipped, a set of gripping plate cylinders 13 is hinged to the hanger 14. The gripping plate cylinders 13 are inclinedly set on the hanger 14, and the telescopic end of the gripping plate cylinders 13 is hinged to the movable gripping plates 12. In order for the fixed plates 11 and the movable gripping plates 12 to cooperate to grip the packaging bag, the bottom surface of the fixed plates 11 is higher than the top surface of the packaging bag, and the top surface of the movable gripping plates 12 is lower than the bottom surface of the packaging bag.

[0040] After the gripper assembly grabs the packaging bag through the above structure, the packaging bag is moved to the top of the pushing platform 20 under the operation of the motor flipping. When the packaging bag is moved to the middle of the pushing platform 20, it is released and the packaging bag falls onto the pushing platform 20. Then, the packaging bag is conveyed in the center by the straightening mechanism.

[0041] As one implementation method in this embodiment, the straightening mechanism is as follows: after the packaging bag falls onto the pushing platform 20, in order to straighten the packaging bag, multiple sets of perforations 21 are provided on the pushing platform 20, with two perforations 21 forming a group, and a hanging plate 24 is suspended on the bottom surface of the pushing platform 20. There are two sets of hanging plates 24, which are symmetrically arranged. A clamping cylinder 299 is provided on the opposite side of the hanging plate 24. A movable plate 25 is provided at the telescopic end of the clamping cylinder 299. A clamping rod 26 passing through the perforation 21 is provided on the outer wall of the movable plate 25. In order to guide the packaging bag when it falls, the clamping rod 26 has an L-shaped structure.

[0042] Therefore, with the above structure, after the packaging bag falls onto the pushing platform 20, the clamping cylinder 299 is activated, and the movable plate 25 drives the clamping rod 26 to center the packaging bag. The top surface of the pushing platform 20 is provided with a pushing cylinder 22 that can transport the packaging bag backward. The telescopic end of the pushing cylinder 22 is provided with a pushing plate 23. A set of hand cranks 27 are rotatably connected to the hanging plate 24. The hand cranks 27 are provided with two threaded sections with opposite directions of rotation, which can manually control the movement of the clamping rod 26.

[0043] When the packaging bag is pushed to the protruding part of the pushing platform 20 by the aforementioned pushing cylinder 22, the packaging bag is driven to the next process by the flipping mechanism.

[0044] As one implementation method in this embodiment, the flipping mechanism consists of two sets of symmetrical mounting plates 30 installed on the frame 4. The two sets of mounting plates 30 are connected by a set of flipping rods 32. The flipping rods 32 are rotatably connected to the mounting plates 30, and two sets of symmetrical connecting arms 33 are provided on the flipping rods 32. The free end of the connecting arms 33 is provided with a set of thumb cylinders 34. Therefore, when using the above structure, the flipping rods 32 are driven to flip by the flipping motor 31 installed on the mounting plate 30 to flip by 90 degrees. Then the thumb cylinders 34 clamp the packaging bag, and then the flipping motor 31 flips back to its original position. Finally, the packaging bag is clamped by the feeding mechanism.

[0045] As one embodiment of this invention, the feeding mechanism is as follows: a support plate 63 is installed on the frame 4, and two support plates 63 are arranged in a group of two. The two support plates 63 on the front side are equipped with a second cylinder 56. The telescopic end of the second cylinder 56 is connected to a first lifting frame 51 with a U-shaped cross section. A reinforcing plate 50 is provided on the outer wall of the first lifting frame 51 to enhance the structural strength. The two groups of first lifting frames 51 are connected by a first guide rod 53, and there are two groups of first guide rods 53. While stabilizing the two groups of first lifting frames 51, it provides support for the slide plate 64. A first fixing frame 57 is installed on the first guide rod 53. A set of opening cylinders 58 is provided on the first fixing frame 57. The telescopic end of the opening cylinder 58 is equipped with a set of opening suction nozzles 59 for opening the packaging bag.

[0046] A set of No. 1 synchronous pulleys 55 are rotatably connected to the outer wall of the No. 1 lifting frame 51. The two sets of No. 1 synchronous pulleys 55 are connected by a No. 1 synchronous belt 52, and the No. 1 synchronous pulleys 55 are driven by a No. 2 motor 54. A slide plate 64 is slidably connected to the No. 1 guide rod 53. The two sets of slide plates 64 are of different lengths, and the ends of the two sets of slide plates 64 are connected to the No. 1 synchronous belt 52 (one set of slide plates 64 is connected to the front side of the No. 1 synchronous belt 52, and the other set of slide plates 64 is connected to the bend of the No. 1 synchronous belt 52). A No. 3 cylinder 60 is provided on the top surface of the slide plate 64, and a No. 2 thumb cylinder 61 is provided at the telescopic end of the No. 3 cylinder 60.

[0047] The two sets of support plates 63 on the rear side are equipped with cylinder 71 of the fourth type. The telescopic end of cylinder 71 of the fourth type is connected to the second lifting frame 70 with a cross section of U-shape. Another set of opening cylinders 58 and opening suction nozzles 59 are provided on the bottom surface of the second lifting frame 70. The two sets of opening suction nozzles 59 are positioned opposite each other. The hopper 62 is located between the two sets of opening suction nozzles 59. The packaging bag is sucked open by the two sets of opening suction nozzles 59 so that the material inside can be filled. After the above operation is completed, the bag receiving mechanism moves it to the bottom of the sealing mechanism. After sealing, the packaging bag is sent away with the assistance of the conveying assembly 40.

[0048] As one embodiment of this example, the bag receiving mechanism consists of: a mounting frame 76 mounted on the rear support of the frame 4, and two sets of mounting frames 76 connected by a second guide rod 77, with a second slider 79 slidably connected to the second guide rod 77. The end face of the second slider 79 is provided with a movable frame 78 with an L-shaped cross-section. A second synchronous wheel 81 is rotatably connected to the mounting frame 76. The two sets of second synchronous wheels 81 are driven by a third motor 80 mounted on the frame 4, and the two sets of second synchronous wheels 81 are connected by a second synchronous belt 82. The movable frame 78 is connected to the second synchronous belt 82.

[0049] A set of sliding telescopic cylinders 83 is provided on the movable frame 78. The telescopic end of the sliding telescopic cylinder 83 is provided with a second movable plate 84, and a third thumb cylinder 85 is provided on the second movable plate 84.

[0050] As one implementation method in this embodiment, the sealing mechanism is as follows: a fixed hanging plate 72 is suspended on the bottom surface of the second lifting frame 70. There are two sets of fixed hanging plates 72. A first moving plate 73 is provided between the two sets of fixed hanging plates 72. The first moving plate 73 is controlled to move by a fifth cylinder 74 installed on the fixed hanging plate 72. A symmetrical sealing element 75 is provided between the two sets of first moving plates 73. The sealing element 75 is a metal electrothermal strip.

[0051] The working principle of this utility model is as follows: A packaging bag is placed on conveyor platform 1. Then, a motor drives conveyor belt 2, which moves the packaging bag towards the pushing platform via partition plate 3. After the packaging bag is moved to the end of conveyor platform 1 by conveyor belt 2, the motor briefly stops. Then, cylinder 6 is activated, extending its telescopic end so that the suction nozzle 8 on the bag-lifting crossbeam 7 contacts the packaging bag. Driven by the pneumatic assembly, the suction nozzle 8 adsorbs the packaging bag. Afterward, cylinder 6 retracts, and motor 10 is activated. Motor 10 drives the guide wheel, which in turn moves the synchronous belt within the reciprocating crossbeam 5. In the working state, the synchronous belt drives the first slider 9 to move on the reciprocating crossbeam 5. After the first slider 9 drives the hanger 14 to move to one end close to the conveyor platform 1, the fixed plate 11 is located above the packaging bag and the movable gripper 12 is located below the packaging bag. Then, the gripper cylinder 13 is activated, which drives the movable gripper 12 to flip and cooperate with the fixed plate 11 to grab the packaging bag and move it to the middle of the pushing platform 20. When it moves to the middle position of the pushing platform 20, the gripper cylinder 13 retracts and contacts the gripping state of the movable gripper 12, causing the packaging belt to fall onto the stacking platform 20.

[0052] Then, the clamping cylinder 299 on the hanging plate 24 is activated. The telescopic end of the clamping cylinder 299 drives the movable plate 25 to move below the pushing platform 20. The clamping rods 26 on the outer wall of the movable plate 25 slide in the perforation 21. The two sets of symmetrical clamping rods 26 center and align the packaging bag. Then, the pushing cylinder 22 is activated. The pushing cylinder 22 sends the packaging bag to the protruding part of the pushing platform 20 through the pushing plate 23. When the packaging bag moves to the protruding part, the stop cylinder 28 is activated, which drives the baffle 29 to rise and block the packaging bag to prevent it from falling off the pushing platform 20.

[0053] Then, the flipping motor 31 on the mounting plate 30 is started. The flipping motor 31 drives the flipping rod 32 to rotate on the mounting plate 30. The flipping rod 32 rotates the connecting arm 33 by 90 degrees. Then, the first thumb cylinder 34 at the free end of the connecting arm 33 clamps the two opposite corners of the packaging bag. Then, the flipping motor 31 flips 90 degrees to reset.

[0054] Then, the second cylinder 56 on the front support plate 63 operates, driving the first lifting frame 51 connected to it to rise and fall. Simultaneously, as the second thumb cylinder 61 descends to the appropriate height, the second motor 54 drives the first synchronous pulley 55 to rotate. The first synchronous pulley 55, through the first synchronous belt 52, drives another set of first synchronous pulleys 55 to rotate. Figure 6As shown, one set of slide plates 64 is connected to the front side of the first synchronous belt 52, and the other set of slide plates 64 is connected to the rear side of the first synchronous belt 52, thereby controlling the two sets of slide plates 64 to move towards each other on the first guide rod 53. Then, the second thumb cylinder 61 clamps the top edge of the packaging bag. After the above operation is completed, the second cylinder 56 resets and the third cylinder 60 on the slide plate 64 is activated to move the packaging bag to the bottom of the hopper 62. Then, the opening cylinder 58 on the first fixing frame 57 and the opening cylinder 58 on the second lifting frame 70 work simultaneously to push the two sets of opening nozzles 59 towards the middle, so that the opening nozzles 59 suck the outer walls of both sides of the packaging bag. Then, the suction force of the opening nozzles 59 opens the packaging bag, and then the hopper 62 opens to discharge the material and fill the inside of the packaging bag.

[0055] Subsequently, motor 80 on frame 4 drives synchronous pulley 81 to rotate. One set of synchronous pulleys 81 is connected to another set of synchronous pulleys 81 via synchronous belt 82. During the rotation of synchronous belt 82, two sets of moving frames 78 (one connected to the front synchronous belt 82, and the other connected to the belt after the turn) slide on guide rod 77 while synchronous belt 82 is working. After adjusting the distance between the two sets of moving frames 78, sliding telescopic cylinder 83 is activated. Sliding telescopic cylinder 83 drives the free end of thumb cylinder 85 to move towards the packaging bag. Once the bag reaches the desired position... The No. 3 thumb cylinder 85 takes over from the No. 2 thumb cylinder 61, completing the handover. Then, the sliding telescopic cylinder 83 resets, and the No. 3 thumb cylinder 85 moves the packaging bag directly below the sealing component 75. Then, the No. 4 cylinder 71 on the rear support plate 63 works, driving the No. 2 lifting frame 70 to move down, so that the opening of the packaging bag is between the two sets of sealing components 75. Then, the No. 5 cylinder 74 on the fixed hanging plate 72 is activated. The No. 5 cylinder 74 pushes the No. 1 moving plate 73 on the telescopic end. The No. 1 moving plate 73 brings the two sets of sealing components 75 into contact, performing heat-sealing on the opening of the packaging bag, completing the final sealing step after the packaging bag is filled with materials. Then, the packaging bags are guided backward by the conveyor assembly 40.
