Description

Technical Field

[0001] This utility model relates to the field of powder packaging technology, and in particular to a bagging device for degreasing powder that prevents sticking. Background Technology

[0002] Industrial degreasing powder is a chemical cleaning agent used to remove grease, oil, and other organic contaminants from the surfaces of materials such as metals. Through chemical dissolution, emulsification, or saponification, it efficiently removes contaminants remaining on industrial parts during processing, transportation, or storage, and is widely used in cleaning processes in machinery manufacturing, automotive parts, and other fields.

[0003] The following technical challenges exist in the packaging process of industrial degreasing powder (such as degreasing powder for metal cleaning): 1. Clumping and adhesion problems: Degreasing powder is prone to absorbing moisture and clumping. The feeding mechanism of traditional packaging equipment is easily clogged, resulting in uneven feeding, loose powder distribution or local accumulation inside the packaging bag, affecting product quality. 2. Low bag opening positioning accuracy: Existing flaring devices mostly use a single mechanical clamp, which makes the packaging bag opening prone to offset or slippage, leading to poor sealing or even powder leakage. 3. Oxidation and deterioration risks: Residual air inside the packaging bag may cause the degreasing powder to oxidize, reducing its chemical activity, especially accelerating deterioration in humid environments. 4. Insufficient sealing adaptability: Conventional heat sealing equipment has a fixed pressure, which cannot adapt to packaging bags of different materials (such as PE, composite film). Overpressure can easily cause the seal to break, while underpressure results in a weak seal. Therefore, there is an urgent need for a packaging device that integrates anti-sticking, precise positioning, inert gas protection, and adaptive sealing. Utility Model Content
