DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application discloses a bag bin assembly of a packaging machine, such as Figure 1 As shown, it includes a support frame 1, a clamping assembly 3 and a bag taking assembly 4. The support frame 1 is fixedly arranged on the packaging machine body. The packaging machine body is provided with two groups of conveyor belts 2 for conveying packaging bags. The support frame 1 is provided with a through slot for the conveyor belts 2 to pass through. The upper end surface of the support frame 1 is provided with a first opening 11, and the first opening 11 is downwardly connected to the through slot. A baffle 12 is arranged on one side of the first opening 11, and the baffle 12 is arranged perpendicular to the upper end surface of the support frame 1. A first support block 121 for supporting the lower end surface of the packaging bag is arranged on the side of the baffle 12 close to the first opening 11.

[0033] The clamping assembly 3 is arranged on the side of the first opening 11 away from the baffle 12. The clamping assembly 3 includes a moving block 31, a second cylinder 32 for driving the moving block 31 to move, a rotating plate 33 and a first motor 34 for driving the rotating plate 33 to rotate. The moving block 31 is slidably arranged on the upper end surface of the support frame 1 in a direction perpendicular to the baffle 12, the cylinder body of the second cylinder 32 is fixedly arranged on the upper end surface of the support frame 1, and the telescopic rod of the second cylinder 32 is fixedly connected to the side of the moving block 31 away from the second opening. The retraction drives the moving block 31 to approach or move away from the first opening 11. The rotating plate 33 is rotatably connected to the moving block 31. The rotation axis of the rotating plate 33 is parallel to the side of the first opening 11 away from the baffle 12. The first motor 34 is fixedly arranged on the moving block 31. The output shaft of the first motor 34 and the rotating plate 33 are coaxially fixedly connected. The rotating plate 33 can be in two states driven by the first motor 34: (a first state in which the surface of the rotating plate 33 is parallel to the horizontal plane and a second state in which the surface of the rotating plate 33 is perpendicular to the horizontal plane). When the rotating plate 33 is in the first state, the upper end surface of the rotating plate 33 and the upper end surface of the first support block 121 are in the same horizontal plane. The upper end surface of the moving block 31 is provided with a positioning block 311 for positioning the packaging bag. In order to prevent interference between the rotating plate 33 and the positioning block 311, a yielding groove 331 for yielding the positioning block 311 is provided on the rotating plate 33. In order to facilitate placing the packaging bag between the positioning block 311 and the baffle 12, a chamfer is provided on the upper end surface of the positioning block 311 near the first opening 11. When the rotating plate 33 is in the second state, the side of the rotating plate 33 near the first opening 11 and the side of the positioning block 311 near the first opening 11 are in the same vertical plane.

[0034] Two clamping plates 5 are arranged on both sides of the first opening 11 perpendicular to the rotation direction of the rotating plate 33. The clamping plates 5 are slidably arranged on the support frame 1 parallel to the rotation direction of the rotating plate 33. A third cylinder 51 for driving the clamping plates 5 to move is arranged on the side of the clamping plates 5 away from the first opening 11. The cylinder body of the third cylinder 51 is fixedly arranged on the upper end surface of the support frame 1. The clamping plates 5 are arranged perpendicular to the upper end surface of the support frame 1. The baffle 12 is driven to move by the two third cylinders 51, so that the two clamping plates 5 clamp the two sides of the packaging bag. In order to enhance the clamping stability of the splint 5 on the packaging bag, a second support block 52 is provided on the side of the packaging bag close to the first opening 11, and the upper end surface of the second support block 52 and the upper end surface of the first support block 121 are in the same horizontal plane. When the two splints 5 are close to each other to clamp the packaging bag, the lower end surface of the packaging bag abuts downward against the second support block 52. In order to further enhance the friction between the splint and the packaging bag, a plurality of strip-like protrusions 53 are provided on the side of the splint 5 close to the first opening 11, and each strip-like protrusion 53 is arranged in a vertical direction. The plurality of strip-like protrusions 53 are evenly arranged along the length direction parallel to the second support block 52.

[0035] The bag taking assembly 4 includes a bracket 43, four vacuum suction cups 44 arranged on the bracket 43 and a first cylinder 41 for driving the bracket 43 to move. The cylinder body of the first cylinder 41 is fixedly arranged in the support frame 1, and a spring rod 42 is arranged at the end of the telescopic rod of the first cylinder 41. The bracket 43 is arranged at the upper end of the spring rod 42 and is driven by the first cylinder 41 to move up and down in the vertical direction. In order to prevent interference between the bracket 43 and the conveyor belt 2, the bracket 43 is arranged between the two conveyor belts 2, and four vacuum suction cups 44 are arranged on the upper end surface of the bracket 43. The four vacuum suction cups 44 are all connected to an air pipe 45. The end of the air pipe 45 away from the vacuum suction cup 44 is connected to the air pump. When the vacuum suction cup 44 moves upward until it abuts against the packaging bag, the vacuum suction cup 44 adsorbs the lower end surface of the packaging bag. During the downward movement of the vacuum suction cup 44 with the bracket 43, the vacuum suction cup 44 drives the lowermost packaging bag to move downward with the bracket 43, and then the air pipe 45 inflates the vacuum suction cup 44 to separate the vacuum suction cup 44 and the bracket 43 continues to move downward so that the two sides of the packaging bag abut downward on the two conveyor belts 2.

[0036] The implementation principle of this embodiment is:

[0037] First, the second cylinder 32 drives the moving block 31 to a suitable position and places the packaging bag between the positioning block 311 and the baffle 12. The third cylinder 51 drives the two clamping plates 5 to approach each other, so that the strip protrusion 53 on the baffle 12 abuts against the side of the packaging bag. The first motor 34 drives the rotating plate 33 to rotate, so that the rotating plate 33 abuts against the side of the packaging bag away from the baffle 12. The first cylinder 41 is started, and the bracket 43 drives the vacuum suction cup 44 to move upward. When the vacuum suction cup 44 abuts against the packaging bag, the vacuum suction cup 44 absorbs the bottom layer of the packaging bag, drives the packaging bag to move downward together, and places the packaging bag on the conveyor belt 2 for transportation processing.

[0038] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
