Description

Technical Field

[0001] This invention relates to the field of granule filling machine technology, specifically a fully automatic high-viscosity granule filling machine. Background Technology

[0002] High-viscosity mixtures containing particles are widely used in industries such as food sauces, chemical slurries, sealants, and pharmaceutical ointments. These materials consist of a high-viscosity matrix mixed with solid particles, exhibiting characteristics such as high viscosity, poor flowability, and significant solid-liquid density differences. This places extremely high demands on the mixing, conveying, anti-clogging, anti-breakage, and precise metering performance of filling equipment. Currently, existing traditional filling machines have simple structures and limited functions, resulting in numerous unresolved technical shortcomings when filling high-viscosity mixtures, severely restricting product filling quality and production efficiency.

[0003] Existing equipment cannot effectively solve the problems of material stratification and uneven particle distribution. High-viscosity materials have extremely poor flowability, and during static and conveying processes, solid particles are prone to sedimentation and aggregation under gravity, resulting in obvious solid-liquid stratification. Traditional filling machines rely solely on simple stirring structures, which have limited stirring range and poor mixing uniformity, failing to achieve a continuous homogenized state of the material. This leads to significant differences in particle content within each filling batch, resulting in uneven particle distribution after filling, poor product consistency, low pass rate, and inability to meet the requirements of standardized mass production.

[0004] Secondly, traditional filling machines have fixed conveying channels, discharge valves, and filling nozzle structures. These channels are narrow and lack anti-clogging buffer structures. When high-viscosity materials are conveyed carrying solid particles, these particles easily get stuck at channel corners, valve gaps, and discharge ports, frequently causing equipment blockages and jamming malfunctions. This leads to production interruptions, high equipment failure rates, and high maintenance costs. Furthermore, traditional conveying structures often employ forced compression conveying methods. Particles are easily subjected to rigid compression and shear abrasion during conveying, making them prone to breakage and deformation. This compromises particle integrity and severely affects product appearance and quality.

[0005] Finally, existing filling equipment suffers from poor metering accuracy and large errors. High-viscosity particulate mixtures are non-Newtonian fluids with extremely unstable flowability, and their viscosity and particle content dynamically change with operating conditions. Traditional filling machines mostly employ fixed-volume metering or simple flow metering structures, which cannot adapt to the rheological characteristics of high-viscosity materials. They cannot adjust the filling speed and discharge rate in real time according to the material's state, leading to inconsistent or discontinuous discharge during the filling process. This directly results in large deviations in single-fill volume, poor batch metering consistency, low overall filling accuracy, and persistently high material filling errors. This not only wastes materials but also significantly reduces the product qualification rate. Summary of the Invention
