Technical Field

The invention relates to the technical field of corrugated rollers, in particular to a novel internal suction type peripheral heating corrugated roller.

Background

The existing corrugated roller structure (see attached figure 2 in the specification) is generally a cylinder body and two shaft heads, and the cylinder body and the shaft heads are welded together through a hot sleeve to form the corrugated roller; the cylinder body is axially provided with uniformly distributed air suction channels, and small holes are distributed in the radial direction and connected with the air suction channels to form an air suction system; the inner cavity of the cylinder body is a heating steam channel, and the structure has a plurality of defects: 1. an air suction channel is arranged in the middle, so that heat exchange is blocked, the temperature of the roller surface is uneven, and the ECT FCT of the produced paperboard is poor; 2. a condensed water film is easily formed on the inner wall of the cylinder body to block heat exchange, so that the temperature of the roller surface is uneven; 2. the machine is easy to deform during the machine halt, and the service life of the corrugated roller is reduced; 3. long preheating time and waste of steam.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: in order to solve the problems existing in the prior art in the background art, a novel internal suction type peripheral heating corrugating roller is provided.

The technical scheme adopted by the invention for solving the technical problems is as follows: a novel inner suction type peripheral heating corrugated roller comprises a central barrel body, wherein the left end of the barrel body is connected with an air suction end shaft head, the right end of the barrel body is connected with an air inlet end shaft head, an air suction channel is arranged in the air suction end shaft head, a steam pipe is arranged in the air inlet end shaft head, axial heating channels are uniformly arranged on the barrel body according to the circumference, and air suction hole groups in different directions from the heating channels are also arranged on the barrel body;

furthermore, the air suction end shaft head and the air inlet end shaft head are fixedly connected with the cylinder body through shrink fit welding, the sealing effect is good, and air blowby is not easy to occur in the using process;

furthermore, the air suction hole group comprises first air suction holes which are arranged in the radial direction at equal intervals and four second air suction holes which are obliquely arranged in the directions of four corners of the cylinder body, and the air suction holes are arranged in the directions different from the heating holes, so that the heating air suction communication caused by the cracking of the two holes is prevented;

furthermore, the opening angle range of the four second air suction holes relative to the horizontal cylinder body is 20-70 degrees, and the four second air suction holes can be designed and adjusted according to actual requirements.

The invention has the beneficial effects that: the novel internal suction type peripheral heating corrugated roller solves the problems in the prior art, and has the advantages that: 1. the traditional steam inner cavity is changed into the air suction inner cavity, so that the air suction channels which are axially and uniformly distributed on the cylinder body can be removed, the roller surface is ensured to be directly heated by steam, and the phenomenon of nonuniform temperature of the roller surface is avoided; 2. the common heating is changed into peripheral heating, so that the problems that a condensed water film is easily formed on the inner wall of the cylinder body, heat exchange is blocked, and the temperature of the surface of the roller is uneven are solved; the machine is easy to deform during the machine halt, and the service life of the corrugated roller is reduced; 3, the structure avoids that the corrugated roller is not only distributed with heating holes but also distributed with air suction holes in the radial direction of the cylinder body in the traditional peripheral heating, so that two holes are cracked, and the corrugated roller is scrapped due to the connection of a heating channel and an air suction system.
