A sealing machine for button cell

Abstract

The utility model provides a button cell sealing machine, including casing, middle part mounting panel, top mounting panel, lift drive component, guide component, punch upper die and punch lower die, lift drive component includes rotation drive part, drive screw, bearing installation shell, thrust bearing, tapered roller bearing, lift platform and connecting block, the inside and outside both sides of tapered roller bearing respectively with upper screw outer end surface, bearing installation cavity inner wall contact. The advantage of this design is that: in the process of rotating, thrust bearing and tapered roller bearing bear axial load, make middle part convex ring not to move and can rotate smoothly in vertical direction, and tapered roller bearing also bears radial load, make the axis not to deviate when upper screw rotates, thereby ensure the accuracy of lift platform ascending distance, and ensure that lift platform is always in horizontal position, improve the effect of button cell sealing, improve the qualified rate.
