Description

Technical Field

[0001] The utility model belongs to the technical field of soft water salt production and processing, and particularly relates to a soft water salt packaging and sealing device. Background Art

[0002] Special salt for water softeners, also known as soft water salt, has sodium chloride (NaCl) as its main chemical component. Due to the daily maintenance of the water softener and the need for resin reduction, the content is required to be above 99.5%. It is generally in the form of balls. After the production of soft water salt is completed, it needs to be sealed and packaged in plastic bags to ensure that it reduces contact with oxygen and extends the storage time of the soft water salt.

[0003] Existing plastic packaging for softened water salt is often sealed using a single-step heating process. While this method is highly efficient, temperature control is crucial due to the single-step molding process. Low temperatures can result in a loose seal, while high temperatures can lead to excessive sealing. Consequently, this method also has a high probability of sealing failure, resulting in high overall cost and loss. Therefore, existing technical solutions require improvement. To address this issue, we have developed a sealing device for softened water salt packaging that addresses these challenges. Utility Model Content
