Description

Technical Field

[0001] The utility model relates to the technical field of paper sizing, in particular to a cooling device for a paper sizing roller. Background Art

[0002] Paper, also known as felt paper, is made from raw materials containing plant fibers through processes such as pulping, modulation, papermaking, and processing. It can be used for writing, printing newspapers and books, packaging, etc. Different from Si, Si is the animal fiber "silk residue", a sheet that can be folded arbitrarily for writing.

[0003] Currently, when paper is produced, a rubber roller is required to guide and transport the paper during the processing. However, when the paper is being processed, the surface temperature is relatively high, which causes the surface temperature of the rubber roller to be relatively high. When the surface of the rubber roller cannot be cooled, the glue on the surface of the rubber roller is likely to stick to the paper, which is very inconvenient and affects the quality of the paper. Therefore, it is necessary to propose a cooling device for a paper sizing roller to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a cooling device for a paper sizing roller, which has the effect of quickly cooling the rubber roller and improving the quality of the paper.

[0015] A further setting of the present utility model is that: rotating rods are installed at both ends of the sizing roller, and a second worm gear adapted to the worm is installed at the end of the rotating rod close to the worm side.

[0016] By adopting the above technical solution, while the worm rotates, it drives the second worm gear to rotate, so that the rotating rod rotates and drives the sizing roller to rotate, for sizing and conveying the paper.

[0017] A further setting of the present utility model is that: the outer side of the rotating rod is rotatably connected to the side plate through a bearing.
