Abstract

The utility model relates to the spinning head of a bottle cap, which is used for the sealing of a bottle cap of a plastic bottle with a threaded bottle opening or a glass bottle. The embossing of a bottle cap and a controlling and regulating system of edge sealing are composed of a lever with rollers, a beveloid, an eccentric shaft and a spring. The utility model has minimum outside dimension, and is particularly suitable for the occasion needing a small bottle distance.

Description

Spining head of bottle cover

The utility model belongs to the device of connection with wrapping of piece.

After being enclosed within bottle cap on the threaded bottleneck, making bottle cap form the screw thread that adapts with bottleneck by certain machinery, and reach this machinery that seals purpose, promptly is spinning head as referred to herein.

In prior art common pattern be adopt one edge sealing roller and two the three-roller type spinning head of dandy roll composition, it controls the action of advancing and retreat together of each roller by the common conical surface, and its significant disadvantages is that the power of advancing of one of them roller is obstructed and will be had influence on the action of all the other two rollers.

The purpose of this utility model, the first is provided with the mechanism that depth-adjustment is gone in each roll-in in order to reduce the accuracy of manufacture of part, makes it to be applicable to the occasion that the compression distance that requires each roller differs, and second it is the spinning head of trying to achieve the out-to-out minimum.

It shown in the accompanying drawing structure diagram of the present utility model.

This utility model has four roller spinning heads of two dandy rolls 5 and two edge sealing rollers 4, each roller has the controlling organization of oneself to finish separately advance and retreat actions, its maximum advantage be to adopt with the upright lever 2 of roller and be positioned at the roller inboard add the independently advance and retreat action that four groups of controlling organizations that upper reset spring 6 forms are realized each roller with the clinohedral 1 of holddown spring and as the eccentric shaft 3 of lever 2 fulcrums.

Adopt this structure, make and the utlity model has following advantage, the regulating action of eccentric shaft can compensate the manufacturing errors of relevant some size of part, can make the accuracy of manufacture of these parts require to reduce, the new operating mode that needing can to realize the compression distance of each roller to differ, out-to-out D of the present utility model is directly by the bottle cap diameter d ₀, the dandy roll diameter d ₁With edge sealing roller diameter d ₂, add that necessary gap forms, Here it is minimum out-to-out.

The utility model is specially adapted to dwindle the occasion of the centre distance of adjacent two spinning heads, for example directly is combined into can, the incorporate can cap rotating machine of spiral cover with bottle placer.

Claims

1, a kind of its formation of bottle cap spinning head comprises the control mechanism that all has separately, finish two dandy rolls 5 and two edge sealing rollers 4 of advance and retreat actions separately, it is characterized in that constituting and also comprise the upright lever 2 of be with roller and the clinohedral that has holddown spring 1 that is positioned at the roller inboard and realize that as four groups of control mechanisms that the eccentric shaft 3 and the retracing spring 6 of this balance pivot are formed the independently advance and retreat of each roller move.
