Description

Rotating sleeve assembly

Technical Field

The utility model relates to the technical field related to mechanical manufacturing, in particular to a rotating sleeve assembly.

Background

The bottle blowing machine is a machine for blowing bottles, and the most obvious explanation is that plastic particles or finished bottle blanks can be blown into the bottles through a certain technological means. The bottle blowing machine is convenient and quick, has large molding quantity, replaces most manual bottle blowing after appearance, and is adopted by most beverage enterprises.

In order to ensure that the manufacturing interval error between every two bottle embryo holders is small, every two bottle embryo holders are connected into a group of bottle embryo holders, every two bottle embryo holders are connected through a hinge piece, the bottle embryo assembled by the bottle embryo holders needs to be turned up and down to carry out the operation of placing the bottle embryo, the bottle embryo holders can generate a pulling force when turning over, the conveying mode of the bottle blowing machine assembly line mainly depends on the hinge piece to connect all the bottle embryo holders, so that the hinge piece can always bear the pulling force, and the bottle blowing machine generally uses about 100 bottle embryo holders, so that the hinge piece bears larger pulling force.

The hinge that adopts at present mostly is a pair of axle sleeve that is used for bottle embryo fixer grafting, and the pivoted connection between the axle sleeve, and generally can adopt rivet riveting mode, connects between the axle sleeve, and the tensile resistance of this mode of connection is not strong, and the rivet takes place the deformation easily, and the aperture of axle sleeve can become longer, even if the hole pitch between every hinge only takes place the change of a silk, when 100 hinges put into use, wholly just is 1 millimeter error, consequently needs to improve the hinge.
