Novel inner suction type periphery heating corrugated roller

Abstract

The invention discloses a novel inner suction type periphery heating corrugated roller. The novel inner suction type periphery heating corrugated roller comprises a center cylinder, the left end of the cylinder is connected with an air suction end shaft head, the right end of the cylinder is connected with an air inlet end shaft head, an air suction channel is formed in the air suction end shaft head, a steam pipe is arranged in the air inlet end shaft head, axial heating channels are evenly mounted on the cylinder according to the circumference, air suction hole sets different from the heating channels in direction are arranged on the cylinder, a traditional steam inner cavity is changed into an air suction inner cavity, common heating is changed into periphery heating, it is ensured thatsteam directly heats a roller face, and the uneven temperature of the roller face can be avoided.

Description

technical field [0001] The invention relates to the technical field of corrugating rolls, in particular to a novel internal suction type peripheral heating corrugating roll. Background technique [0002] Existing corrugated roll structure (see the attached figure 2 ) is generally a cylinder, two shaft heads, and the cylinder and the shaft heads are welded together by heat sleeve to form a corrugated roller; there are evenly distributed suction channels in the axial direction of the cylinder, and small holes and suction channels are distributed radially. The channels are connected to form a suction system; the inner cavity of the cylinder is a heating steam channel, and this structure has many disadvantages: 1. There is a suction channel in the middle, which blocks heat exchange, makes the temperature of the roller surface uneven, and the produced cardboard ECT FCT is poor ; 2. Condensed water film is easy to form on the inner wall of the cylinder, which blocks heat exchange...

There is a suction channel in the middle, which blocks heat exchange, makes the temperature of the roller surface uneven, and the produced cardboard ECT FCT is poor ;2. It is easy to form a condensed water film on the inner wall of the cylinder, which blocks heat exchange and makes the temperature of the roller surface uneven; 2. The shutdown is easy to deform, and the service life of the corrugated roller is reduced; 3. Long preheating time wastes steam
