After being manufactured, the printing plants are usually used for printing plastic packages.
In the use process of a printing factory, the service life of the plate roller is limited, and when the service life of the plate roller exceeds the service life, the plate roller exceeding the service life needs to be returned to the plate-making factory for restoration. Before repair, the chrome plating layer on the surface of the plate roller needs to be removed. In the prior art, during chromium removal, chromium removal liquid easily enters the inside of the plate roller, the cleaning of the chromium removal liquid existing in the plate roller is very troublesome, and during the cleaning, the working environment is easily damaged, so that the health of workers is influenced.
Disclosure of Invention
The utility model aims to overcome at least one of the defects in the prior art and provide a rotating shaft for preventing chromium liquid from advancing and retreating inside a plate roller. The rotating shaft consists of shaft body components, and the rotating shaft applicable to the plate rollers with different lengths can be obtained through the combination of the shaft body components with different specifications, so that the production flexibility is improved; in addition, the sealing rings are arranged at the two ends of the shaft body assembly, so that chromium removing liquid can be prevented from flowing into the printing roller from the abutting part of the adjacent shaft body assembly.
The aim of the utility model can be achieved by the following technical scheme:
a rotating shaft for preventing chromium liquid from advancing and retreating inside a plate roller, which consists of a plurality of shaft body components which are sequentially abutted; the shaft body assembly comprises a shaft body and sealing rings arranged on two sides of the shaft body. The arrangement of the sealing ring can prevent chromium removing liquid from flowing into the printing roller from the abutting part of the adjacent shaft body assembly, and inconvenience is brought to subsequent cleaning.
Further, the first grooves for placing the sealing rings are formed in the two sides of the shaft body.
Further, the groove depth of the groove is smaller than the ring width of the sealing ring.
Further, the shaft body is made of one of CPE, CSM or PVC.
Preferably, the shaft body is made of PVC.
Further, the end of the plate roller is of a circular ring structure; when the plate roller end head of the plate roller is abutted with the shaft body, the plate roller extends inwards along the outer end face of the shaft body, and the inner diameter of the plate roller end head is gradually reduced.
Further, at least one shaft body component is arranged in the rotating shaft. Specifically, the shaft body assembly is formed by combining shaft body assemblies with different lengths according to the lengths of various specifications, so that the plate roller suitable for different lengths can be obtained.
Further, the plate roller is inserted in the rotating shaft, and the inner surface of the end surface of the plate roller is abutted with the outer surface of the rotating shaft.
Further, the thickness of the shaft body is 1-3mm. Preferably, the thickness of the shaft body is 2mm.
Compared with the prior art, the utility model has the following advantages:
(1) The rotating shaft designed by the utility model for preventing the chromium liquid from advancing and retreating inside the plate roller is composed of the shaft body components, and the rotating shaft suitable for the plate rollers with different lengths can be obtained through the combination of the shaft body components with different specifications, so that the production flexibility is improved; in addition, the production cost is reduced because the rotating shaft does not need to be customized for each length of plate roller.
(2) According to the utility model, the sealing rings are arranged at the two ends of the shaft body assembly, so that chromium removing liquid can be prevented from flowing into the plate roller from the abutting part of the adjacent shaft body assembly.
