Capping apparatus and capping system for bottle filling device

A capping apparatus for a bottle filling device, comprising:

• a capping head main body 30,
• a first slide body 41 which is slidable up and down with respect to the capping head main body 30, and
• a capping door mechanism M, which includes a door structure 39, a connecting rod 40, and a movable door 37, is hinged with the capping head main body 30 and the first slide body 41;
• a cap sucking head 43, which is slidable up and down and which is connected to a mechanism driving the cap sucking head 43 to move up and down, the cap sucking head 43 being adapted to move downwards to apply bottle caps 94 onto containers via the capping head main body 30;
• a middle slide body 48 arranged in a radial direction between the cap sucking head 43 and the first slide body 41, the middle slide body 48 being capable of sliding up and down, and to move downwards to act on the first slide body 41 in order to drive the first slide body 41 to move downwards,
• a spare distance disposed at upper and lower directions of the middle slide body 48 and the first slide body 41, so that the middle slide body 48 will not be able to act on the first slide body 41 while moving downwards at an initial stage of a bottle capping process;
• wherein the capping apparatus also includes a second spring 44 and a first spring 49, in which the second spring 44 is compressed to act on the middle slide body 48 along with the downward movement with the cap sucking head 43, and meanwhile, the first spring 49 is located between the capping head main body 30 and the first slide body 41, and supports the first slide body 41;
• and
• the capping apparatus is also provided with one or more cap inlet chutes 300, wherein a lower end of a cap slideway 104 is connected to the capping head main body 30.

• the capping apparatus is also provided with one or more cap inlet chutes 300,
• wherein the cap sucking head 43 has a step surface 430 at a lowermost end thereof that is able raise the middle slide body 48 and the first slide body 44 when the cap sucking head 43 moves upwards, and
• the middle slide body 48 has a lower end portion 481 which is raised by the step surface 430 before the first slide body 41 is raised during the bottle capping process.
