Abstract
The invention discloses an air cushion furnace with a V-shaped roller supporting device and application of the air cushion device. The air cushion furnace comprises an air cushion box which is used for suspending a belt by blowing air to the upper surface and the lower surface of the belt. A belt suspension conveying channel is formed between upper air cushion box units and lower air cushion box units. A plurality of transmission rollers are arranged below the suspension conveying channel in parallel, and the radial size of the transmission rollers becomes larger gradually to the two ends from the middles to form V-shaped supporting parts with the sections in a V shape. By means of the structure design of the air cushion box, when the thick belt sinks due to the large self weight when passing through the suspension conveying channel, the two sides of the belt are erected on the V-shaped supporting parts of the transmission rollers; the transmission rollers play the supporting role, meanwhile, the V-shaped supporting parts of the transmission rollers are only in line contact with the two sides of the belt, and the surface quality of the belt is not influenced; and V-shaped gaps exist below the belt so that compression air below can enter and continuously support and convey the belt, the belt can be continuously heated evenly, and the working efficiency is high.
