  • Publication number: 20240316614
    Abstract: Equipment for high-speed stable neck is modularized on existing equipment and achieves high-speed production by ensuring can stability when entering the can neck forming mold forming through multiple repositioning and includes a loading station and sets of neck forming stations; the loading station includes a loading transfer turntable, with vacuum adsorption grooves on circumferential surface; a stable transition station is between the loading and neck forming stations; the stable transition station includes first and second stable turntables, each having vacuum adsorption grooves on circumferential surface; when the first stable and loading transfer turntables rotate, the can body enters the first stable turntable vacuum adsorption groove through the first calibration junction from the loading transfer turntable vacuum adsorption groove; when the first and second stable turntables rotate, the can body enters the second stable turntable vacuum adsorption groove through the second calibration junction from th
