AI Technical Summary
Existing wrapping machines are mainly suitable for goods with similar sizes. When the size of the goods differs greatly, wrapping waste is serious, and the pallet is too large, making it inconvenient to rotate the small goods.
A multi-ring pallet adjustable stretch wrapping machine was designed. The controller adjusts the synchronous lifting of the ring pallet and the disc. With the help of electric slide rails and servo motors, the distance between the stretch wrapping film and the goods can be adjusted and the film can rotate synchronously to meet the wrapping needs of goods of different sizes.
It effectively reduces waste of wrapping film, improves the efficiency of wrapping goods of different sizes, is highly adaptable, and reduces reliance on pallets.
