The present invention discloses a glass bottle annealing and cooling device, which belongs to the technical field of glass bottles, and comprises a support plate and a vertical block, and the vertical block is movably mounted on the top wall of the support plate. In this scheme, a memory alloy wire is arranged, and after the memory alloy wire is heated and stretched, the first spring drives the push block to move upward through the linkage block and the first mounting rod, and makes the lower clamping rod drive the clamping plate to clamp the glass bottle, and then as the memory alloy wire continues to stretch, the first spring continues to drive the push block to move upward, and in the process of the push block continuing to move upward, the upper clamping rod drives the clamping plate to clamp the glass bottle, and at this time, the push block is out of contact with the lower clamping rod, and then the clamping plate is reset and out of contact with the glass bottle, thereby effectively preventing the clamping plate from contacting with the glass bottle for a long time and affecting the cooling effect at the contact point between the glass bottle and the clamping plate, thereby improving the weakening effect of permanent stress in the annealing and cooling of the glass bottle.
