Guide mechanism of pressure cover of star wheel group of automatic capping machine

Abstract

The invention relates to a guide mechanism of a pressure cover of a star wheel group of an automatic capping machine. The guide mechanism is arranged at one side of a pressure cover star wheel; the guide mechanism comprises a cylinder, a connecting plate and a guide body; the cylinder is fixedly connected to a cylinder mounting plate; a guide sleeve is fixed to a connecting plate which is arranged at the front end of a piston rod of the cylinder; the guide sleeve is provided with a guide body. The guide mechanism of the pressure cover of the star wheel group of the automatic capping machine has the beneficial effects of being high in recurrence precision and good in operability, overcoming quality problem of an aerial fog tank, ensuring coaxial positioning of a tank cover and an aerial fog agent tank, and therefore ensuring reliability and stability of the pressure cover.

Description

technical field [0001] The invention relates to a capping positioning device for an aerosol can, in particular to a capping guiding mechanism of a star wheel group of an automatic capping machine. Background technique [0002] At present, capping machines at home and abroad often use an indexing mechanism with gap movement to drive the rotation of the star wheel shaft. Two sets of star wheels are fixed on the star wheel shaft. The lower star wheel set drives the aerosol can to rotate and feed, and the upper star wheel set drives the can. The cap is rotated and fed, and the capping action is performed at a certain station, so there are the following problems: 1. Due to the offset between the mouth of the aerosol can and the center of the bottom of the can, there is a coaxial deviation between the can lid and the aerosol can. 2. The connection between the upper star wheel set and the star wheel shaft adopts key gap fit (to adapt to different tank heights and needs to move up a...

Problems solved by technology

[0002] At present, capping machines at home and abroad often use an indexing mechanism with gap movement to drive the rotation of the star wheel shaft. Two sets of star wheels are fixed on the star wheel shaft. The lower star wheel set drives the aerosol can to rotate and feed, and the upper star wheel set drives the can. The cap is rotated and fed, and the capping action is performed at a certain station, so there are the following problems: 1. Due to the offset between the mouth of the aerosol can and the center of the bottom of the can, there is a coaxial deviation between the can lid and the aerosol can

2. The connection between the upper star wheel set and the star wheel shaft adopts key gap fit (to adapt to different tank heights and needs to move up and down), and is locked with bolts. It is difficult to coincide with the center and the axis and will shift during the locking process

3. Due to the light weight of the can lid, the shape of the can lid has a certain taper, and the capping stroke is long, there is a phenomenon that the can lid will drift during the capping process
