[0002] As a crucial core component of sealing devices, sealing rings are widely used in various household appliances containing liquids, such as the hard plastic parts of coffee machines, due to their compact structure, simple manufacturing, and quick installation. However, because the sealing rings themselves are small in size, have low elasticity, and their inner walls need to fit tightly with the outer circumference of the workpiece, the insertion process requires strong internal support to ensure a smooth sliding into place, placing extremely high demands on the continuity of the process.

[0003] Currently, most of the sealing rings are installed manually. However, manual installation can lead to uneven stress and installation problems such as flipping, warping, and not being able to fit the ring completely, which can cause appliances to leak and become unusable.

[0020] The inner support module 21 includes a plurality of inclined block assemblies arranged circumferentially, an inner support rod 211 movably disposed among the plurality of inclined block assemblies, and an inner support drive component 212 for driving the inner support rod 211 to rise and fall; specifically, the inner support drive component 212 is a cylinder. The outer peripheral surface of the inner support rod 211 is a conical surface, and the inner side surface of each inclined block assembly is provided with a first inclined surface adapted to the conical surface.

[0021] The inclined block assembly includes an inclined block 213, a fixed seat 214 disposed on the outside of the inclined block 213, and an elastic element 215 disposed between the fixed seat 214 and the inclined block 213; the first inclined surface is disposed on the inner side of the inclined block 213. Specifically, the elastic element 215 is a spring. The conical surface of the inner support rod 211 has a structure that gradually decreases in size from bottom to top, and the first inclined surface of the inclined block 213 and the conical surface of the inner support rod 211 have a wedge-shaped fit structure. When the inner support rod 211 rises, all the inclined blocks 213 are pushed outward and unfolded to achieve internal support for the sealing ring; when the inner support rod 211 descends, the inclined blocks 213 are reset and retracted under the action of the elastic element 215.

[0022] The uncoiling module 22 includes an uncoiling plate 221 and an uncoiling plate drive component 222 for driving the uncoiling plate 221 to rise and fall.
