Description

Technical Field

[0001] The present invention relates to the technical field of cleaning mechanisms, and more specifically, to a multi-column liquid filling and cleaning mechanism. Background Art

[0002] Filling equipment is mainly a small category of products in packaging machines, and is widely applicable to industries such as medicine, food, beverage, daily chemicals, grease, pesticides, and other special industries. From the perspective of packaging materials, it can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines. In terms of the degree of production automation, it is divided into semi-automatic filling machines and fully automatic filling production lines. In recent years, with the improvement of the scientific and technological level, domestic filling equipment has developed rapidly, and there have been great improvements in aspects such as technical level, equipment performance, and equipment quality, playing an important role in supporting the efficient and safe production of enterprises or factories.

[0003] The cleaning methods of filling machines mainly include manual cleaning, direct flushing with cleaning agents, and cleaning with cleaning devices. Manual cleaning usually occurs during the downtime of the filling equipment. Workers disassemble the parts to be cleaned for separate cleaning. This method increases the labor intensity of workers, is time-consuming and laborious, has low cleaning efficiency, is prone to damage the equipment due to frequent disassembly, and the cleaning is not hygienic enough, indirectly affecting the filling efficiency and making it difficult to meet the filling requirements on a fully automatic canning production line. Direct flushing with cleaning agents means adding the prepared cleaning agent through the feed pipe for flushing. This method is limited by the number, position of the feed pipes, and flushing pressure. Only relying on the shaking of the cleaning agent for cleaning, it cannot thoroughly clean the cleaning blind spots, leaving a hygiene hazard, which in turn affects the quality of the product during filling. Cleaning with cleaning devices means cleaning through specific cleaning structures or cleaning devices. However, the existing cleaning mechanisms of filling machines have disadvantages such as complex structures, inconvenient installation, incomplete cleaning, and stubborn stains remaining. Moreover, the parts of the device have high precision requirements, large processing difficulties, and a single cleaning method, and are not easy to operate.

[0004] For the problems in the related art, no effective solutions have been proposed yet. Summary of the Invention

[0005] The purpose of the present invention is to provide a multi-column liquid filling and cleaning mechanism to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

The stirring mechanism includes a stirring motor, and the spraying mechanism includes a spraying ball. The stirring motor is arranged at the top of the 50L material bucket, and the stirring motor drives the stirring blade to rotate. There are two rotating spraying balls arranged inside the 50L material bucket, and it is branched in through the first three-way. One end of the first pneumatic butterfly valve is connected to the breathing valve, and the other end is connected to the first three-way. The first three-way is connected to the second pneumatic butterfly valve, and the second pneumatic butterfly valve is connected to the elbow. The second pneumatic butterfly valve is connected to the first three-way through a pipeline. One end of the first three-way is connected to one end of the third pneumatic butterfly valve, and the other end of the third pneumatic butterfly valve is connected to the buffer waste bucket. The other end of the second three-way is connected to the fourth pneumatic butterfly valve;
