Cover film adding device of yoghourt cup

Abstract

The invention discloses a cover film adding device of a yoghourt cup, the yoghourt cup comprises a cup body and a cup cover, the cup opening of the cup body is provided with a flange extending outwards, and the outer edge of the flange is connected with a cup cover connecting part extending upwards; the cover film adding device comprises a rack, a first driving mechanism, a second driving mechanism, a suction cup assembly, a guide plate, a conveying template and an ejector rod, the suction cup assembly, the guide plate, the conveying template and the ejector rod are sequentially arranged from top to bottom, the suction cup assembly comprises a rotating wheel and a suction cup installed on the rotating wheel and used for adsorbing a cover film, a through hole allowing a cup body to penetrate through is formed in the conveying template, the cup body is erected on the conveying template through a flanging frame, the second driving mechanism drives the ejector rod to eject the cup body upwards so that a cup cover connecting part can abut against the guide plate, and the guide plate is provided with a cover film guide hole. The bottom aperture of the cover film guide hole is between the inner diameter of the flange and the outer diameter of the flange, and the suction cup releases the cover film in the cover film guide hole so that the cover film can cover the flange.

Description

【Technical field】 [0001] The invention relates to the technical field of mother-child cup production, in particular to a cover film installation device for a yogurt cup. 【Background technique】 [0002] The existing yogurt cup includes a cup body, the cup mouth of the cup body is provided with a flange extending outward, and a cover film is heat-sealed on the flange, and the existing cover film adding device is used to add the flange to the above-mentioned yogurt cup. When the cover film is installed, when the suction cup with the cover film moves to the flange, the cover film is released and covered on the flange. [0003] In order to improve the market competitiveness of yogurt cups, technicians have developed a new type of yogurt cup, which includes a cup body and a cup lid. The cup lid connecting part is connected with the cup lid connecting part, a lid film covering the mouth of the cup is sealed on the flange, and a cavity for accommodating granular materials or spoons...

AI Technical Summary

Problems solved by technology

If the existing cover film installation device is used to continue to add a cover film to the new yogurt cup, in the case of an unsatisfactory position for the suction cup to absorb the cover film, it is easy to cause the entire cover film to fall off, and then the cover film cannot cover the mouth of the cup, thus Reduce the qualification rate of cover film installation
