The process of breaking of Glass tubing clips in the process that Glass tubing descends at lower chuck as shown in Figure 4, and the glass of fusing shrinks and more and more thinner to the centre earlier under capillary effect, disconnects at last, and the following molten glass of breakpoint forms a bottle end.Because in the middle of most molten glass concentrates on, thus the bottle end and thin state around the thick middle can appear, again because the acting in conjunction of gravity and mass force, can be to lower recess at bottle the end, the degree of its depression is obvious all the more along with the increase in bottle footpath.Though in the system bottle process at the end, the basic skill or training's preface of rubbing can also be set, but peripheral part at the bottom of the head that rubs can only touch bottle, center at the bottom of not reaching bottle, thus the end of rubbing be merely able to make the length dimension of vial more accurate, the defective of center thin and central dip around thick at the bottom of can not changing bottle.

According to the regulation of national standard, to be not less than a certain numerical value just qualified for the thickness of thinnest part at the bottom of the glass bottle.The intermediary situation obviously was disadvantageous at the bottom of above-mentioned most of molten glass concentrated on bottle, the molten glass that forms the bottle end is limited, blocked up other parts that must cause of a part are thin excessively, and scrap rate is increased, and the thickness at the bottom of how just making bottle evenly becomes one technical problem to be solved.

Summary of the invention

The present invention is for addressing the above problem the blowing device that a kind of bottle-making machine is provided, and makes that it is simple in structure, can make bottle base thickness degree even.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

A kind of blowing device of bottle-making machine, comprise cylinder, blowpipe, bellows component, stationary ring, rotating ring and lower chuck, described blowpipe has centre hole, blowpipe is installed on the core bar of cylinder, bellows component is installed on the blowpipe, stationary ring is installed on the bellows component, and the core pipe that rotating ring is installed in lower chuck bottom.

The jaw seat upper surface of above-mentioned lower chuck is provided with a plane, has an aperture to communicate with the endoporus of core pipe in the middle of the plane.

In system bottle process, after vial is broken, the last plane contact of the bottleneck end face of vial and lower chuck jaw seat and form sealing, at this moment the core bar of cylinder is released blowpipe, bellows component and stationary ring is risen, when stationary ring with just formed complete gas passage after the rotating ring that is installed in lower chuck core pipe foot contacts, at this moment in the centre hole of blowpipe, blow, bottle bottom is heaved in the glass of melted state, realize blowing at the end.

Compared with prior art, the invention has the advantages that:

Realize in vial, blowing with simple device, bottle bottom is heaved in the glass of melted state, eliminate the shortcoming of the inhomogeneous and bottle center, the end of bottle base thickness degree to lower recess.

Embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

As Fig. 1, Fig. 2, shown in Figure 3, a kind of blowing device of bottle-making machine, constitute by cylinder 1, blowpipe 2, bellows component 3, stationary ring 4, rotating ring 5 and lower chuck 6, described cylinder 1 is installed in directly or indirectly needs the station place of blowing on the support of bottle-making machine, blowpipe 2 has centre hole, and blowpipe 2 is installed on the core bar of cylinder 1, and bellows component 3 is installed on the blowpipe 2, stationary ring 4 is installed on the bellows component 3, and the core pipe 61 that rotating ring 5 is packed in lower chuck 6 bottom.

The jaw seat upper surface of above-mentioned lower chuck 6 is provided with a plane 62, has an aperture to communicate with the endoporus of core pipe 61 in the middle of the plane 62.

In system bottle process, after vial is broken, the bottleneck end face of vial contacts with the last plane 62 of lower chuck 6 jaw seats and forms sealing, at this moment the core bar of cylinder 1 is released blowpipe 2, bellows component 3 and stationary ring 4 is risen, when the upper surface 41 of stationary ring 4 with just formed complete gas passage after the lower surface 51 of rotating ring 5 contacts, at this moment in the centre hole of blowpipe 2, blow, bottle bottom is heaved in the glass of melted state, realize blowing at the end.Blow at the end, the molten glass transition towards periphery at leisure of bottle center, the end, at last again through rubbing at the end, just can form thickness evenly, the highly consistent bottle end.
