However, currently widely used pallet stretch film packaging machines have some drawbacks. They are not convenient for covering the top of goods with film. In practical applications, many goods have high requirements for top protection. For example, if the top of electronic and electrical products is not covered by stretch film during transportation, dust and moisture can easily penetrate and affect their performance. If the top of food products is exposed, they will not only face the risk of contamination but may also experience quality degradation due to moisture loss.

[0004] Therefore, a lifting device for a stretch film packaging machine is proposed. Utility Model Content
