Use of Air Shafts:
1. Wide application: The convex key type air shaft is an independently designed part, ranging from 1 inch to 12 inches. The length and size are determined by the actual needs of the customer. Where there is slit printing, rewinding, coating, and bag making, papermaking, etc. Inflatable shafts can be applied to work equipment or other related center winding machinery.
2. Economical and efficient: The design of the shaft is designed for actual work needs, and it can be applied to various types of coils, such as thickness and width.
3. Long use time and simple maintenance: Although the inflatable shaft is a part of the machine, each part in its own structure has a fixed specification and can be used interchangeably, making it easy to maintain. .
4. Single accessory: The inflatable shaft is a single part of the rewinding and unwinding machine. Each part in its structure has a fixed specification and size, which can be decomposed and combined to make maintenance convenient and durable.
5. Professionalism: There are professional engineers and technicians for market research on the design, installation and use of inflatable shafts.
6. Large bearing capacity: The inflatable shaft can be designed according to the actual model, using high-quality steel to increase the bearing capacity. For example, steel materials can be selected for those with a bearing weight of more than 1 ton.
7. Short operating time: It only takes 2 seconds to inflate and deflate the roll tube to separate and place the roll tube. It is simple and convenient to place the roll tube, safe and applicable. It can be applied to all the machinery and equipment used for winding and unwinding. Shafts. The length of the inflatable shaft can be up to six meters or more, and the length can be up to several hundred millimeters. The length is determined according to the needs of customers.
8. The keyed inflatable shaft expands to a single key strip, and the fulcrum spreads to each key strip to balance the force, which is suitable for mechanical rewinding of articles with heavier carrying capacity.
