High-speed capping machine

Abstract

The invention provides a high-speed capping machine which is characterized by comprising a protective cover, wherein the two sides of the protective cover are provided with a bottle inlet station and a bottle outlet station respectively; an oscillation type aluminum cover feed device is arranged in the protective cover; a downward-oblique aluminum cover chute is arranged at the outlet of the oscillation type feed device; a bottle feed plate is arranged below the aluminum cover chute; one end of a bottle inlet screw is arranged beside the bottle inlet plate, and the other end is arranged beside the bottle inlet station; one end of a bottle outlet screw is arranged beside the bottle outlet station, and the other end is arranged beside a bottle outlet plate in the protective cover; and a rotary capping device with at least 12 rolling heads and 12 built-in single blades is arranged between the bottle inlet plate and the bottle outlet plate. The high-speed capping machine provided by the invention has the advantage that the single-machine output meets the current and future requirements for the speed of the washing, baking, pouring, freezing and rolling production line, and conforms tothe new specification.

Description

technical field [0001] The invention relates to a capping machine, which is used in the capping and sealing process of aluminum caps or aluminum-plastic composite caps in glass bottle powder injections, freeze-dried powder injections and water injection pharmaceutical manufacturers. Background technique [0002] In the pharmaceutical equipment market, the early single-head manual capping machine had a low speed and could only reach 60 bottles / min. Since the end of the 1980s, capping machines with various structures have appeared one after another. Among them, the representative ones are the three-knife screwing and pressing type, the four-jaw clamping type and the multi-head eccentric large-plate single-knife structure. The speed is also increased to about 200-300 bottles / min. Through the use of my country's pharmaceutical manufacturers for many years, it is reflected that there are different defects. [0003] The three-knife screwing and pressing type has the disadvantag...

AI Technical Summary

Problems solved by technology

[0003] The three-rolling knife screwing and pressing type has the disadvantages of difficult adjustment of the rolling head and rolling knife for high-production multi-head capping machines, which is time-consuming and laborious, and requires debugging personnel to have a high technical level.

And this structure has a theoretical deadly debugging blind spot for vials of 2ml and below

Because the rolling angle and position of the rolling knife are not easy to control accurately, it is easy to cause broken bottles

[0004] The four-jaw clip type is not easy to control accurately due to its elasticity, and there are also shortcomings in the structural manufacturing process for high-speed capping.

[0005] Although the structure of the multi-head eccentric large plate single rolling knife is simple and easy to adjust, and the manufacturing cost is low, but this structure also correspondingly increases the requirements for glass bottles, rubber stoppers and aluminum-plastic caps

In actual production, it is difficult to make higher requirements on bottles, stoppers and caps based on the fixed and unique benchmark of large pan knives

Due to reasons such as manufacturing and assembly, a single large plate rolling knife will have a linkage effect on vials in different rolling stages during the rolling process, which will affect the uniform sealing effect of capping

[0006] The promulgation and implementation of the new version of GMP, as well as the increase in the output of other equipment in the washing, drying, filling and freezing rolling production line, have put forward higher requirements for the capping process. Failure to adapt to new requirements
