Circular double-layer glassware circumferential sealing welding technology and equipment

The invention discloses a circular double-layer glassware circumferential sealing welding technology and equipment. The technology specifically comprises the following steps: step 1, clamping inner and outer glass tubes of double-layer glassware to be processed on rotating equipment to ensure synchronous rotation; step 2, heating mouth areas of the inner and outer glass tubes to be welded to soften the mouth areas; step 3, providing the outer wall of the outer glass tube with a stop block for preventing the radial movement of the outer glass tube, speeding up the rotation of the inner and theouter glass tubes, and enabling the soft part of the inner glass tube to move toward the inner wall direction of the outer glass tube and to be welded with the inner wall of the outer glass tube underthe action of centrifugal force; and step 4: stopping the heating and rotation when the mouth areas of the inner and outer glass tubes reach a set welded state, and removing the processed double-layer glassware from the rotat
