Classification and concept of commonly used air shafts

The main types of inflation shafts on the market are: slat, key and through-bar, and slip inflatable shafts (air expansion shafts) are more commonly used. Specifically:

1. Slat-type air expansion shaft (lug type air expanding shaft): The expansion part of the slat-type air expansion shaft (air expansion shaft) is a plate, which can be applied to machinery with high winding precision or light winding items.

2. Key bar type air expanding shaft (lug type air expanding shaft): The expansion part of the key bar type air expansion shaft is a key bar, which can be applied to items with heavy mechanical winding capacity.

3. Through-bar air expansion shaft (air expansion shaft): The expansion part of the through-bar air expansion shaft (multi bladder type air expanding shaft) is a through-length key bar, which has the characteristics of high precision, high load-bearing and light weight.

4. Slip inflation shaft (key type differential shaft ): slip inflation shaft (air expansion shaft) has been widely used in plastic film, metal foil, paper roll; Slitting and winding of PVC sheet coils.
