[0002] The structure of the embossing roller of the new gravure color printing machine is different from that of the traditional embossing roller. The rubber and shaft of the traditional embossing roller are integrated and cannot be disassembled. In order to improve the flexible production, the new embossing roller adopts a rubber sleeve combined with an air expansion shaft. When replacing the rubber sleeve of the embossing roller, the air expansion shaft of the embossing roller needs to be deflated and inflated to achieve the replacement of the sleeve. The existing embossing sleeve is usually manually operated during transportation and installation. However, since the sleeve cannot directly contact the ground during transportation and installation and replacement, the embossing sleeve needs to be suspended as a whole, which has problems such as inconvenient transportation and installation of the embossing sleeve, high labor intensity of operators, and time-consuming and laborious operation.
