Description

Technical Field

[0001] This invention belongs to the field of beverage filling technology, specifically a beverage filling device and method. Background Technology

[0002] Beverages are liquid foods intended for direct human consumption. They are made primarily from water through various processing techniques and aim to replenish fluids, provide nutrition, or meet specific functional needs. Their core characteristics include: liquid drinkability, diverse raw materials, complex processes, and targeted functions. Filling equipment is specialized equipment used to automatically or semi-automatically fill liquids, pastes, granules, or powders into containers. It is one of the core pieces of equipment for automating material packaging in modern industrial production. Its design aims to improve production efficiency, ensure filling accuracy, reduce human error, and adapt to the special needs of different industries for material characteristics. Beverages require filling during processing; therefore, a beverage filling device and method are needed.

[0003] In the use of beverage filling equipment and methods, the processed beverages are usually directly conveyed and filled through the feeding system. However, when filling fruit and vegetable juices or dairy protein beverages, there may be residual fiber impurities or clumps in the raw materials, which can easily clog the filling structure during filling, requiring machine shutdown for cleaning and affecting the continuity of production. Therefore, it cannot meet people's needs. Summary of the Invention

[0013] As a further aspect of the present invention: a beverage filling method, comprising the following steps: S1. The conveying structure conveys the beverage bottles and positions them below the filling structure; S2. The main gear controls the rotation of the first transmission gear through the transmission external gear ring, so that the first lead screw transmission structure controls the filling head to be inserted into the beverage bottle for filling beverage through the first lifting tube. S3. The feeding system starts and replenishes the filtered beverage to the filling structure through the filter belt; S4. The filling head is reset and the position of the filter belt is adjusted by the first synchronous belt structure so that the first cleaning scraper cleans the filter belt. S5.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) The filling method adopted in this invention is equipped with a multi-stage filter box in the feeding system. The filter screen belt in the filter box has progressively smaller filter holes from top to bottom, realizing multi-stage gradient filtration of beverages. It can fully intercept impurities of different particle sizes in beverages. Through the cooperation of the second drive motor, half gear and second transmission gear, the two liquid valves can be automatically switched alternately. When a set of feeding pipelines or filter components need maintenance, it can be quickly switched to another set of pipelines to continue feeding without stopping the machine, effectively ensuring production continuity. The pipeline switching response is rapid, the structure is simple and reliable, and the maintenance cost is reduced. Through the transmission cooperation of the first drive motor, main gear, transmission external gear ring and first transmission gear, several first screw transmission structures are driven to work synchronously, realizing that multiple sets of first lifting pipes drive the filling head to lift synchronously and accurately, effectively avoiding the alignment deviation between the filling head and the bottle mouth of the beverage, reducing beverage leakage, ensuring the stability of the filling process, improving the efficiency of beverage filling, and avoiding clogging of the filling device. No machine stoppage maintenance is required, which improves the use effect of the filling method.

[0015] (2) The present invention, through the setting of a first cleaning component and a second cleaning component, sets a first cleaning scraper, a rotating roller, a tapping strip and the first cleaning component to form a multi-dimensional cleaning structure, which can scrape, tap and negative pressure adsorb cleaning of the filter belt and the transmission roller, effectively removes stubborn impurities attached to the surface. The second cleaning scraper in the cleaning box can automatically clean the first feeding trough to avoid the accumulation of impurities. The first scraper and the second scraper in the cleaning adsorption box clean the filter and the second feeding trough respectively, further improving the cleaning effect. The first synchronous belt structure drives the filter belt to move and the second synchronous belt structure to operate, realizing the linkage between the filter belt position adjustment and the tapping cleaning. The third drive motor controls the movement of the second cleaning scraper, the first scraper, the second scraper and the sealing block through the bevel gear structure and the transmission rod, realizing the coordinated work of multiple cleaning components, improving the reliability of equipment operation, improving the cleaning effect of the first cleaning component and the second cleaning component, and improving the use effect of the filling device.

[0016] (3) The present invention uses a second cleaning component that is automatically triggered by changes in negative pressure suction. When the filter is clogged, the negative pressure suction increases and drives the lifting block to rise. Through the coordinated operation of the first lifting gear, the first lifting rack, the rotating gear, the first winding wheel, the guide wheel, the second lifting gear, the second winding wheel, and the second lifting rack, the striking block is driven to knock and clean the filter. The first support spring and the second support spring realize the reciprocating knocking of the striking block, making the cleaning more thorough. The whole process does not require manual monitoring and operation, realizing intelligent self-cleaning of the filter, reducing manual maintenance costs, extending the service life of the cleaning adsorption box, improving the cleaning effect of the second cleaning component, and improving the use effect of the filling device.
