Description

Technical Field

[0001] The utility model belongs to the technical field of milk powder processing, and in particular relates to a feeding device for a milk powder packaging machine. Background Art

[0002] The production process of milk powder includes milk collection, filtration, standardization, degreasing, drying, crushing and other steps. The final product mainly contains nutrients such as protein, fat, minerals and vitamins in milk. During the fermentation process, the lactose in the milk is decomposed by lactic acid bacteria to produce lactic acid. These products have certain health effects on the human body.

[0003] For example, the authorization announcement number "CN216270013U" is named a quantitative feeding device for milk powder processing and packaging. Although the first vibrator can be started during the process to assist in feeding, and the second vibrator can be turned on during the process of unloading the milk powder in the pre-storage box to assist in feeding and avoid blockage, the existing quantitative feeding device for milk powder processing and packaging uses the vibration frequency of the vibrator to speed up the feeding process of milk powder packaging. However, the milk powder is a finer powder. The powdered milk powder falling from the top will be squeezed into a compaction at the bottom of the feeding hopper. The compacted milk powder holds together and is difficult to be shaken apart by the force of vibration. Therefore, it is easy to affect the falling of the subsequent fed milk powder, resulting in uneven feeding problems, which ultimately leads to the poor feeding effect of the existing quantitative feeding device for milk powder processing and packaging.

[0004] At present, the quantitative feeding device for milk powder processing and packaging has dust and dust floating in the air during the processing and feeding process of milk powder, because the vibrator and other working equipment inside the milk powder processing and packaging machine require motors or other electric equipment to assist in work. After the dust enters the gaps of the motor and mechanical equipment, it is not only inconvenient to clean, but also easy to clog the working parts of the motor and mechanical equipment, thereby causing problems such as overheating of the mechanical equipment or parts failure, which affects the service life of the quantitative feeding device for milk powder processing and packaging.
