Seal clamping device for sealing machine

Abstract

The invention discloses a seal clamping device for a sealing machine and belongs to the field of office equipment. The seal clamping device structurally comprises a positioning nut matched with a rack, and a seal positioning mechanism fixedly connected with the positioning nut. The seal clamping device is characterized in that magnets are arranged at the upper end of the positioning nut to serve alignment connecting pieces; the seal positioning mechanism comprises a conical inner thread fixing sleeve and a conical outer thread opening and closing lock sleeve matched with a conical inner thread; an inner body of the conical outer thread opening and closing lock sleeve is matched with an outer body of a positioning seal body; and the seal positioning mechanism is positioned at the lower end of the positioning nut through a threaded structure. Due to the fact that the conical outer thread opening and closing lock sleeve with different inner locking cavity shapes is designed for adapting to replacement of round, square and even elliptical seals, and in addition, the conical shape and the design of a contraction joint of the conical outer thread opening and closing lock sleeve are used for meeting the requirement for clamping and fixing of seals of the same kind and different specifications, and thus the seal clamping device can have multiple purposes.

AI Technical Summary

Problems solved by technology

[0003] The structure design of the existing card and fixture is too complicated, which makes it inconvenient to disassemble and install the stamp holding device. At the same time, the stamp stamping machine is only suitable for stamps with a single shape and a single specification. Standard stamp jackets meet the needs of stamp fixation, resulting in poor versatility of the stamp clamping device for stamps of different specifications, which is obviously very inconvenient for small-scale units
