Inflatable sleeve

Abstract

The invention relates to an inflatable sleeve. The wall of the sleeve is of a composite layer structure. The composite layer structure comprises an inflatable layer, a first elastic layer, a filling layer, a second elastic layer and a shaping layer which are sequentially arranged from inside to outside in the radial direction of the sleeve. The inflatable layer can elastically deform under the pressure of an inflatable shaft and is tightly arranged on the inflatable shaft in a sleeving manner. The first elastic layer and the second elastic layer are both light elastic material layers. The filling layer is a light and hard material layer. The shaping layer is a hard material layer. All the adjacent structural layers are connected in a composite manner. The inflatable sleeve has the advantages that the mass is small, the dismounting and mounting efficiency of the sleeve and a mandrel is high, the shaping layer is not prone to deformation, and the printing effect is good.

Description

technical field [0001] The present application relates to the field of printing rollers, in particular to an inflatable sleeve. Background technique [0002] The printing roller is an important working part in the printing machine. The printing roller includes a mandrel and a sleeve tightly fitted on the mandrel. When printing, print on the outer peripheral surface of the sleeve by spraying or pasting printing materials such as screen lines. The sleeves used in the printing rollers in the prior art are all steel sleeves. In order to enable the steel sleeves to rotate synchronously with the mandrel, the mandrel of the printing roller and the steel sleeve need interference fit during assembly. [0003] The problem with the steel plate sleeve in the above prior art is that due to the high rigidity and heavy weight of the steel plate sleeve, it is difficult, time-consuming and laborious to assemble the mandrel and the steel plate sleeve; moreover, after the assembly of the mand...
