Description

Technical Field

[0001] The utility model relates to the technical field of logistics conveying equipment, in particular to a bag stacking machine. Background Art

[0002] Flexible packaging rolls are typically produced in rolls and then packaged. After being rolled, the flexible packaging film undergoes multiple processes, including sorting, stacking, transporting, boxing, and packaging. Traditionally, these packaging processes are often performed manually. While manual packaging is simple, it is highly repetitive and therefore well-suited to mechanization.

[0003] The Chinese utility model patent with publication number CN221916163 U discloses an automatic ton bag stacking machine, which limits the ton bag by clamping it on four sides with a first clamping component and a second clamping component, and cooperates with a lifting component to separate the ton bag from the pallet, thereby realizing automatic operation of the entire ton bag stacking process. However, since soft packaging coils are heavy and deform when subjected to pressure, existing stacking machines find it difficult to grab soft packaging coils for stacking. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0022] Example 1:

[0023] like Figure 1 and Figure 2 As shown, a bag stacking machine includes a conveying mechanism 1 and two brackets 2 arranged on the left and right sides of the conveying mechanism 1, a lifting frame 4 is arranged on the bracket 2, and a lifting mechanism 5 for driving the lifting frame 4 to move up and down is arranged on the top of the bracket 2, and each lifting frame 4 is respectively provided with a clamping mechanism 6.

[0024] In this embodiment, the conveying mechanism 1 adopts a powered conveying roller conveyor, and two brackets 2 are located on both sides of the powered conveying roller conveyor. A top frame 3 is provided at the top of the bracket 2, and the top frame 3 is connected between the left and right brackets 2.

[0025] The lifting mechanism 5 includes two transmission shafts 501 and a motor 505. The two transmission shafts 501 are mounted on the top frame 3 via bearing blocks and are located at the top ends of the corresponding brackets 2. The motor 505 is mounted on the top frame 3 and connected between the two transmission shafts 501 via a transmission assembly 506, driving the two transmission shafts 501 to rotate synchronously. The motor 505 is a hydraulic motor, and the transmission assembly 506 utilizes a conventional sprocket chain. Sprockets are mounted on the transmission shafts 501 and the output shaft of the motor 505, respectively, and a chain is used to connect the sprockets for transmission.

[0026] A first transmission wheel 502 is installed at both ends of each transmission shaft 501, a second transmission wheel 503 is provided at the bottom of the bracket 2, a lifting chain 504 is connected between the first transmission wheel 502 and the second transmission wheel 503, and the lifting frame 4 is fixedly connected to the lifting chain 504. The first transmission wheel 502 and the second transmission wheel 503 are both sprockets.

[0027] like Figure 2 As shown, the clamping mechanism 6 includes a moving seat 601, which is installed on the lifting frame 4 through a slide rail 604. The lifting frame 4 is provided with a driving element 602 for driving the moving seat 601 to move. The driving element 602 adopts a cylinder or an oil cylinder, which is used to drive the moving seat 601 to move in the horizontal direction and perpendicular to the conveying direction of the conveying mechanism 1, so that the two moving seats 601 on the left and right sides move toward each other or move back to back.

[0028] like Figure 3 As shown, a clamping frame 603 is provided at one end of the movable base 601 facing the conveying mechanism 1. The clamping frame 603 is fixed to the movable base 601. A clamping surface 6031 is provided on the side of the clamping frame 603 facing the conveying mechanism 1. The clamping surface 6031 is arranged to be inclined outward, that is, the distance from the upper end of the clamping surface 6031 to the conveying mechanism 1 is greater than the distance from the lower end of the clamping surface 6031 to the conveying mechanism 1. The distance between the two clamping surfaces 6031 on the left and right sides of the conveying mechanism 1 gradually decreases from top to bottom.

[0029] The inclination angle a of the clamping surface 6031 relative to the horizontal plane is 80-87°, and is preferably 85° in this embodiment.

[0030] The clamping frame 603 is a long strip structure and is arranged horizontally. The cross-section of the clamping frame 603 is U-shaped.

[0031] The movable base 601 is provided with a plurality of clamping frames 603. In this embodiment, there are three clamping frames 603, and the three clamping frames 603 are spaced apart in an upper and lower manner. The distance h2 between two adjacent clamping frames 603 is greater than the height h1 of a single clamping frame 603. For example, if the height h1 of a single clamping frame 603 is 10 cm, the distance h2 between two clamping frames 603 is 10.5 cm.

[0032] In this embodiment, the clamping surfaces 6031 of the three clamping frames 603 located on the same movable base 601 are all located in the same plane.

[0033] When the movable seats 601 on the left and right sides are clamping the soft packaging material, the soft packaging roll is deformed by the clamping action. The deformation of the soft packaging roll produced by the clamping frame 603 at the bottom is the largest during the clamping process, while the deformation of the soft packaging roll produced by the clamping frame 603 at the top is the smallest during the clamping process. The unclamped part of the soft packaging roll is deformed and enters the gap between the upper and lower adjacent clamping frames 603. In this way, the soft packaging roll becomes a shape with a small bottom and a large top, which is not easy to slide down from the clamping frame 603. At the same time, the inclined clamping surface 6031 can also support the soft packaging roll in the vertical direction, ensuring the stability of the soft packaging roll during the clamping process.

[0034] Example 2:

[0035] like Figure 4 As shown, the difference from Example 1 is that the three clamping frames 603 of the movable seat 601 are distributed in a front-to-back spacing in the left-right direction, so that the three clamping surfaces 6031 are arranged in parallel and distributed in a front-to-back spacing, wherein the front-to-back spacing distance d between the upper and lower adjacent clamping surfaces 6031 is 1-5 cm, and the clamping surface 6031 located at the bottom is closer to the conveying mechanism 1.
