Rotating device for ampoule bottles

Abstract

The invention discloses a bottle rotating device used for an ampoule. The device comprises a bottle rotating base, a synchronous pulley, a bottle rotating small shaft, a bottle rotating upper shaft, a swing central shaft and a friction wheel. The swing central shaft which is linked with a swing mechanism is arranged on the bottle rotating base. The bottle rotating small shaft is arranged in a hole, which is arranged on the bottle rotating base. The bottom end of the bottle rotating small shaft is connected with the synchronous pulley, and the upper end is connected with the bottle rotating upper shaft. The friction wheel is arranged on the top end of the bottle rotating upper shaft. The bottle rotating upper shaft is a connecting rod, which is provided with a flexible part. The invention has the advantages of simple and compact structure, convenient installation and low cost. The invention is the bottle rotating device used for the ampoule, which leads to the result that the friction wheel clings to the ampoule tightly and gives the ampoule proper pressure when the invention is working.

Description

technical field [0001] The invention mainly relates to the field of medicine packaging, in particular to a bottle-rotating device for ampoule bottles on an ampoule wire drawing filling and sealing machine. Background technique [0002] In the prior art, as shown in Figure 7, the bottle spinner device for ampoule bottles on the ampoule wire drawing filling and sealing machine includes a bottle spinner base 10, a timing pulley 9, a small spinner shaft 7, an upper spinner shaft 16, and a swing center shaft 11. The friction wheel 3 and the spring 17, the swing center shaft 11 connected with the swing mechanism is installed on the bottle seat 10, the swing mechanism drives the bottle seat 10 to complete the swing through the swing center shaft 11, and the small shaft 7 of the spin bottle passes through the bearing 8 Installed in the hole opened on the spin bottle seat 10, the bottom end of the spin bottle small shaft 7 is connected with the timing pulley 9, and the upper end is c...

AI Technical Summary

Problems solved by technology

In this structure, since the friction wheel 3 and the bottle base 10 are rigidly connected through the small shaft 7 and the upper shaft 16 of the bottle, it is required that the bottle base 10 is a flexible body that can float when rotating the ampoule bottle 1 so that it can be rotated. When the bottle holder 10 swings, the friction wheel 3 is provided with an appropriate pressure, which requires an additional mechanism to make the bottle holder 10 floatable. In some technical solutions, it is realized by a spring 17, so the whole bottle holder becomes relatively stable. Complicated, the manufacturing cost is high, and the effect is not obvious
