Nitrogen filling equipment and method for nasal spray

Abstract

The invention discloses nitrogen filling equipment and method for a nasal spray, and the equipment comprises a feeding conveying belt, a bottle separation rotating disc, a base, a filling machine, a vibration feeder, a gland nitrogen filling device and a discharging conveying belt; a nitrogen filling method adopting the equipment comprises the following steps that 1, spray bottles are fed through the feeding conveying belt, the empty bottles are conveyed to the station of the filling machine, and the nasal spray is filled into the bottles through the filling machine; secondly, the canned nasal spray bottles are conveyed to a station of a gland nitrogen charging device through a bottle dividing rotary table, a positioning mechanism positions and locks the spray bottles, an air cylinder drives an outer cover to cover the spray bottles, and a nitrogen charging mechanism vacuumizes the bottles and charges nitrogen into the bottles; thirdly, the nitrogen filling mechanism keeps vacuumizing and nitrogen filling, after the vibrating feeder and the capping mechanism framework cover the upper cap, the cap pressing mechanism presses and binds the spraying agent cap, filling of one bottle is completed, and vacuumizing and nitrogen filling are stopped; and fourthly, the spray bottles subjected to filling and capping are conveyed to a discharging conveying belt through a bottle distributing rotary disc to be discharged.

Description

technical field [0001] The invention relates to the technical field of nasal spray production, in particular to a nitrogen-filled filling equipment and method for nasal spray. Background technique [0002] As a nasal spray, it is usually sensitive to oxygen, so it needs to be filled with nitrogen for protection when filling. Usually, nitrogen is filled in the canning space from the beginning, so that the oxygen in the environment is discharged, and the canning and sealing are all carried out under nitrogen filling. This method requires airtight space, which is very difficult; and because the filling machine is on the assembly line, the empty bottles are continuously sent to the filling station, which means that the filling station must be filled with nitrogen at all times, which consumes a lot of nitrogen. , Although the price of nitrogen and oxygen is not high, it is also a waste to use it in this way. But if not, the residual oxygen content in the packaged bottle is extr...

AI Technical Summary

Problems solved by technology

This method requires airtight space, which is very difficult; and because the filling machine is on the assembly line, the empty bottles are continuously sent to the pile filling station, which means that the filling station must be filled with nitrogen at all times, which consumes a lot of nitrogen. , although the price of nitrogen and oxygen is not high, it is also a waste to use it in this way

However, if this is not the case, the residual oxygen content in the packaged bottle is extremely high, which shortens the shelf life of the nasal spray

[0003] In addition, the specific gravity of nitrogen is smaller than that of oxygen, and the effect of continuous nitrogen filling is not good. According to the test, the residual oxygen in the bottle can reach 10-15%
