Description

[0002] In the packaging industry, flat nozzle packaging machines play an important role in the packaging of various materials. However, traditional flat nozzle packaging machines face severe challenges in quantitative processing of paste-like raw materials.

[0003] In the prior art, traditional quantitative methods, such as volumetric quantitative or simple weighing quantitative, often fail to achieve ideal accuracy and stability when dealing with paste-like raw materials. When using volumetric quantitative, since the paste-like raw materials are prone to adhering to the container wall, there is a large deviation between the actual discharged material quantity and the set value. Moreover, the viscosities of paste-like raw materials in different batches may vary, further affecting the quantitative accuracy. In terms of weighing quantitative, the slow flow and uneven distribution of paste-like raw materials make it difficult to obtain stable and accurate weight data in a short time, thus affecting the packaging efficiency and quality. In addition, the structure and control system of traditional flat nozzle packaging machines also have deficiencies when dealing with paste-like raw materials. Their feeding systems may not be able to convey paste-like materials evenly and stably, resulting in fluctuations during the quantitative process, and the response speed and accuracy of the control system are insufficient to make timely and effective adjustments to the complex quantitative requirements of paste-like raw materials.
