Star wheel quick change structure

Abstract

The invention discloses a rapid star wheel replacing structure. The rapid star wheel replacing structure comprises a star wheel body, a plurality of bottle protection plates, a compression ring and a locking element, wherein the star wheel body comprises a first wheel disc, a second wheel disc and a support frame; the first wheel disc and the second wheel disc are connected by use of the support frame and are arranged up and down; a plurality of positioning pins arranged around the circumferential direction of the first wheel disc are arranged on the first wheel disc; a plurality of grooves formed around the circumferential direction of the second wheel disc are formed in the second wheel disc; each bottle protection plate comprises a bottle protection part, a first mounting part arranged on the first end of the back of the bottle protection part, and a second mounting part arranged on the second end of the back of the bottle protection part, the section of the bottle protection part is circular-arc-shaped, a pin hole matched with the corresponding pin is formed in the first mounting part and a lug boss matched with the corresponding groove is arranged on the second mounting part; the plurality of bottle protection plates are arranged at the peripheries of the first wheel disc and the second wheel disc; the lug bosses are clamped in the grooves; the positioning pins are clamped in the pin holes; the compression ring is pressed on the first mounting parts and connected with the first wheel disc by use of the locking element. The rapid star wheel replacing structure is capable of realizing quick replacement of star wheels different in bottle shapes.

Description

technical field [0001] The invention relates to filling equipment, in particular to a star wheel quick change structure. Background technique [0002] The star wheel mainly plays a transitional role in the transmission process of the filling machine: it takes over the bottle passed from the previous process, and lowers or raises the height of the bottle to the height of the bottle delivery chain, such as figure 1 As shown, in the beverage production process, the same filling machine usually produces several bottle types of beverages. Generally, when changing the bottle type, it is necessary to replace the star wheel to adapt to different bottle types. When replacing the star wheel, it is necessary to Loosen the locking handle 20 connected to the star wheel seat 10, and then replace the star wheel 30 as a whole; the disadvantages of this method are: 1. The star wheel 30 welded into one body is quite heavy, and requires 2 to 3 people to cooperate to replace it. It is quite la...

[0002] The star wheel mainly plays a transitional role in the transmission process of the filling machine: it takes over the bottle passed from the previous process, and lowers or raises the height of the bottle to the height of the bottle delivery chain, such as figure 1 As shown, in the beverage production process, the same filling machine usually produces several bottle types of beverages. Generally, when changing the bottle type, it is necessary to replace the star wheel to adapt to different bottle types. When replacing the star wheel, it is necessary to Loosen the locking handle 20 connected to the star wheel seat 10, and then replace the star wheel 30 as a whole; the disadvantages of this method are: 1. The star wheel 30 welded into one body is quite heavy, and requires 2 to 3 people to cooperate to replace it. It is quite labor-intensive and time-consuming. Once there are many types of bottles and frequent switching is required, it is very time-consuming and affects production efficiency; 2. When there are many types of bottles, many types of star wheels need to be made, which is costly
