Description

Technical Field

[0001] This utility model relates to a packaging machinery device, specifically a bag-turning device. Background Technology

[0002] In existing packaging machines, after the material is weighed, when the material is fed into the packaging bag through the bag clamp in the hopper, the two corners of the packaging bag are often not filled with material due to material flow problems or the packaging bag having an inner lining that is not flat enough. This affects the stability of the packaging bag when it is fully loaded with material, and may even affect the sewing effect.

[0003] Currently, no existing technology has been found that can solve this problem. Therefore, there is an urgent need to design a turning device to address the aforementioned technical issues. Summary of the Invention

[0005] The concept of this utility model is to flip the bottom of the packaging bag during the material packaging process, lift the middle of the packaging bag, and fill the corners of the bag with material, thereby solving the problem that the two corners of the packaging bag cannot be filled with material.

The drive assembly is installed inside the main frame assembly. The two output ends of the drive assembly are respectively hinged to the inner walls of the two top plate assemblies at their respective ends, and are used to drive the two top plate assemblies to rotate around their respective hinge axes with the main frame assembly to achieve inversion.

[0007] Furthermore, the drive assembly includes a drive cylinder, two upward-spinning support assemblies, a first downward-spinning support assembly, and a second downward-spinning support assembly; The drive cylinder is located inside the main frame assembly; One end of the first upper-spinning support assembly and the first lower-spinning support assembly are hinged together to the tailstock of the drive cylinder; One end of the second upper rotating support assembly and the second lower rotating support assembly are hinged together at the output end of the drive cylinder; The other ends of the two upper rotating support components are respectively hinged to the inner wall of the top plate component at one end close to each other; The other ends of the first and second downward-spinning support components are respectively hinged to the inner sidewall of the main frame component and mesh with each other.

[0008] Furthermore, both of the aforementioned upper-rotation support assemblies include two upper-rotation support arms; Both the first and second downward-spinning support assemblies include two downward-spinning support arms. The length of the lower rotating support arm is greater than the length of the upper rotating support arm; One end of each of the two upper rotating support arms and the two lower rotating support arms is respectively mounted on both ends of the same rotating shaft, which is correspondingly mounted on the tailstock or output end of the drive cylinder; The other ends of the two upper rotating support arms are respectively hinged to the inner wall of the top plate assembly, and the other ends of the two lower rotating support arms are respectively hinged to the corresponding inner side wall of the main frame assembly. The other ends of the two downward-spinning support arms in the first and second downward-spinning support assemblies are respectively meshed by gears.

[0009] Furthermore, the drive cylinder is a pneumatic cylinder.

[0010] Furthermore, each of the two top plate assemblies has a bent portion extending toward the interior of the main frame assembly at one end close to the other.

[0011] Furthermore, the bent portion is a 1 / 4 circular arc bent structure.

[0012] The beneficial effects of this utility model are: 1. This utility model uses a driving device to drive the top plate assembly to lift upwards from the middle of the packaging bag, thereby allowing the material inside the packaging bag to automatically fill the corners of the bag.

At their opposite ends, each top plate assemblies 3 has a bent portion extending into the main frame assembly 1. In this embodiment, the bent portion is specifically a 1 / 4 arc bend structure. This design prevents damage to the packaging bag during unpacking. Furthermore, the two top plate assemblies 3 are spaced apart at their opposite ends to prevent interference when the top plate assemblies 3 are driven by the drive assembly 2 to rotate around their respective hinge points with the main frame assembly 1 during use.

[0020] The dimensions of the two top plate components 3 can be set according to the actual size of the packaging bag. The total area of ​​the two top plate components 3 should not be less than the upper opening area of ​​the main frame component 1. In this embodiment, no specific examples are given.

[0021] The main function of the drive component 2 is to drive the two top plate components 3 to rotate around their respective hinge axes with the main frame component 1, thereby achieving overturning.

The end of the second rotating shaft is tapered, and the tapered part of the second rotating shaft mates with the inner tapered part of the mounting shaft. The rotating shaft and the mounting shaft are connected by screws. The middle threaded hole of the mounting shaft is connected to the lever of the cylinder, thereby installing the second rotating shaft at the output end of the cylinder.

[0027] The other ends of the upper support arms of the two upper support assemblies 22 are respectively hinged to the inner walls of the top plate assembly 3 at one end close to each other via internal thread shafts; the other ends of the lower support arms of the first lower support assembly 23 and the second lower support assembly 24 are respectively hinged to the lower side of the inner side wall of the main frame assembly 1 via internal thread shafts.
