Description

Technical Field

[0001] The utility model relates to the field of corrugated rollers, in particular to a corrugated roller. Background Art

[0002] The corrugating roller is the most important component of the corrugated board production equipment. It is generally made of 48CrMoA steel. After surface heat treatment and cold treatment or surface cold treatment, its hardness is generally above HRC55. In the prior art, when the wavy teeth on the surface of the corrugating roller are damaged, the entire corrugating roller needs to be replaced, which is very troublesome and greatly increases the cost of use. Therefore, those skilled in the art provide a corrugating roller to solve the problems raised in the above background technology. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a corrugated roller, comprising a roller body and semi-arc wave teeth, wherein a plurality of slots are symmetrically provided on the outer surface of the roller body, a plurality of fan-shaped cavities are symmetrically arranged inside the roller body, and the fan-shaped cavities are located on the upper side of the slots, the inner wall of the fan-shaped cavity is slidably connected to the fan-shaped plate, a clamping block is installed at the lower end of the fan-shaped plate, and the clamping block passes through the fan-shaped cavity and one end of the slot;

[0004] Threaded rods are symmetrically arranged inside the roller body, and the threaded rods pass through a number of fan-shaped cavities and fan-shaped plates. A number of semi-arc wave teeth are symmetrically arranged on the outer surface of the roller body. Insert blocks are installed on the inner walls of the semi-arc wave teeth, and the positions of the insert blocks correspond to the slots. A card slot is opened at one end of the insert block, and the card slot corresponds to the position of the card block.

[0005] Preferably, roller shafts are installed at the left and right ends of the roller body.

[0006] Preferably, the threaded rod is rotatably connected to the inside of the roller body.

[0007] Preferably, the sector plate and the threaded rod are threadedly connected.

[0008] Preferably: a cross slot block is installed at the upper end of the threaded rod.

[0009] Technical effects and advantages of the utility model:

[0010] When the utility model needs to replace a new semi-arc wave tooth, the threaded rod is driven to rotate by the cross groove block, so that the fan-shaped plate drives the clamping block to rise and leave the clamping slot. Then, the semi-arc wave tooth that needs to be replaced is disassembled from the surface of the roller body, and a new semi-arc wave tooth is replaced, and its inserting block is inserted into the slot. Then, the cross groove block is reversed, so that the fan-shaped plate drives the clamping block to move and insert into the clamping slot, so that the semi-arc wave tooth is fixed on the outer surface of the roller body, thereby quickly completing the replacement of the semi-arc wave tooth, which is convenient and fast and reduces the use cost.
