Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, in particular to a weighing hopper for a palletizer. Background Art

[0002] In logistics and manufacturing, palletizers are essential equipment for neatly stacking goods. The weighing hopper, a key component of the palletizer, is responsible for accurately measuring and loading materials. However, existing palletizer weighing hoppers have significant shortcomings, particularly in their inability to detect material weight and effectively clear the hopper bottom to prevent material blockage. These issues not only affect production efficiency but can also lead to material waste and safety hazards.

[0003] Existing palletizer weighing hoppers typically lack built-in weight detection, making it difficult for operators to monitor the exact weight of the material within the hopper in real time. This deficiency can lead to multiple problems in practice. Firstly, due to the inability to accurately determine the material loading amount, overloading or underloading can occur. Overloading not only increases the burden on mechanical equipment, shortens its service life, and may also pose safety risks; while underloading reduces production efficiency and increases unit product manufacturing costs. Secondly, the lack of weight detection makes it difficult for automated control systems to achieve precise material management, limiting the overall intelligence level of the production line.

[0004] Existing palletizer weighing hopper designs fail to adequately address effective unblocking of the material hopper bottom, which can easily lead to material blockage. This blockage not only impedes the normal flow of material but also forces operators to frequently shut down the machine for manual cleaning, increasing maintenance workload and time costs. Blockage is particularly problematic when handling materials prone to agglomeration, such as powders and granules. For example, certain materials with high humidity can adhere to each other after prolonged standing, forming large clumps and further exacerbating the potential for blockage. In such cases, traditional mechanical vibration or pneumatic purging methods often have limited effectiveness and cannot completely resolve the problem.

[0005] Material blockages not only reduce production efficiency but can also cause equipment damage. When the bottom of the hopper is clogged, material cannot be discharged smoothly. The accumulated pressure causes additional stress on the hopper walls and other related components, which can easily cause structural deformation or cracking over time. Furthermore, to clear the blockage, operators may need to use tools to forcibly clear the blockage, which not only increases labor intensity but also may cause accidental damage to the equipment. Even more seriously, in extreme cases, the sudden loosening and fall of the blockage can pose a direct safety threat to nearby personnel.

[0006] The existing palletizer weighing hopper lacks an effective dredging mechanism, which also limits its adaptability in complex working conditions. Different materials have different physical properties, such as density, fluidity, friction coefficient, etc. These properties determine the behavior of the material in the hopper. For materials with poor fluidity or easy to agglomerate, traditional hopper designs are difficult to meet the requirements of efficient and smooth operation.

[0007] Therefore, how to provide a palletizer weighing hopper is a problem that those skilled in the art urgently need to solve. Utility Model Content
