Problems solved by technology

For the punching machine, the roller shaft has been in the developer solution for a long time. Because the developer solution is highly alkaline and highly corrosive, the roller shaft surface is easy to crystallize during use, and the crystallization on the roller shaft surface will scratch the plate surface. As a result, the washing quality of the plate is affected, so the roller shaft needs to be taken out frequently for cleaning and maintenance, which is time-consuming and laborious, which in turn affects the washing efficiency of the plate

Embodiment Construction

[0012] The present invention is described below in conjunction with accompanying drawing.

[0013] as attached figure 1 Shown is a roll shaft according to the present invention, including a roll shaft body 1, and an anti-corrosion layer 2 is provided outside the roll shaft body 1; the anti-corrosion layer 2 is a carbon fiber layer; the anti-corrosion layer 2 is PTFE layer.

[0014] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

[0015] The roller shaft of the present invention has an anti-corrosion layer on the outside of the roller shaft body, which has strong corrosion resistance, avoids the surface crystallization of the roller shaft, and improves the washing quality of the plate, so that the roller shaft does not need to be taken out frequently for cleaning and maintenance, saving time and effort. In turn, the washing efficiency of the plate is increased.

Abstract

The invention relates to a roll shaft, comprising a roll shaft body, wherein a corrosion-resistant layer is arranged outside the roll shaft body; the corrosion-resistant is a carbon fiber layer; or, the corrosion-resistant is a polytetrafluoroethylene layer. The roll shaft disclosed by the invention is strong in corrosion resistance because the corrosion-resistant layer is arranged outside the roll shaft body, thereby preventing crystallization on the surface of the roll shaft, improving the washing quality for a plate, preventing the roll shaft from being taken-out, cleaned and maintained frequently, saving time and labor, and further increasing the washing efficiency for the plate.

Description

technical field [0001] The invention relates to a roller shaft, in particular to a roller shaft used in a printing punching machine, and belongs to the technical field of printing equipment parts. Background technique [0002] At present, most of the equipment in the printing industry uses opposed rollers to convey various thin media, such as paper and aluminum plates. For the punching machine, the roller shaft has been in the developer solution for a long time. Because the developer solution is highly alkaline and highly corrosive, the roller shaft surface is easy to crystallize during use, and the crystallization on the roller shaft surface will scratch the plate surface. Thereby affecting the washing quality of the plate, so the roller shaft must be taken out for cleaning and maintenance frequently, which is time-consuming and laborious, and then affects the washing efficiency of the plate. Contents of the invention [0003] In view of the above-mentioned technical pro...
