Roll-in composite forming machine for arc-shaped hollow glass

The invention belongs to the technical field of glass processing, and discloses an arc-shaped hollow glass rolling composite forming machine, which comprises: a rack, which is formed by welding profile steel and is used for the installation of other devices; the upper chain plate pressing cylinder structure is mounted in the rack in an up-down sliding manner through a hydraulic structure and is used for pressing the top of the hollow glass; the lower chain plate pressing cylinder structure is fixedly mounted at the bottom end of the rack and used for pressing the bottom end of the hollow glass; the infrared heating device is fixedly mounted at the top end of the upper chain plate pressing cylinder structure and is used for heating the hollow glass; the problem that in the prior art, due to the fact that the contact range between the arc-shaped hollow glass and the lower chain plate pressing cylinder structure is too small, the arc-shaped hollow glass swings left and right in the conveying process is solved, a
