Description

Roll changing device and conveying device Technical Field The utility model relates to the technical field of glass conveying, in particular to a roll changing device and a conveying device. Background The electronic glass is a high-technology product applied to the fields of electronics, microelectronics and optoelectronics, is mainly used for manufacturing integrated circuits and glass materials with photoelectric, thermoelectric, acousto-optic, magneto-optic and other functional components, and has very broad application prospects. In the electronic glass production line, a belt is required to be used for conveying, a large number of lower carrier rollers are arranged below the belt, and the lower carrier rollers can play roles in supporting the belt and preventing the belt from deviating. The lower carrier roller runs in an environment with serious dust for a long time and can be worn and damaged, so that the lower carrier roller needs to be replaced frequently. In the prior art, when the lower carrier roller is replaced, the belt is usually required to be stopped, so that blocking can occur, and the replacement efficiency is low. Disclosure of utility model The utility model mainly aims to provide a roll changing device, which aims to solve the problems that blocking easily occurs and the changing efficiency is low when a lower carrier roller is changed in the prior art. In order to solve the above problems, the present utility model provides a roll changing device, comprising: A mounting frame; An auxiliary roller set comprising two first auxiliary rollers connected to the top end of the mounting frame at intervals along a first direction, and The driving assembly is installed on the installation frame and connected with the auxiliary roller set in a driving mode so as to adjust the relative distance between the auxiliary roller set and an external belt.
