Description

Technical Field

[0001] The utility model relates to the technical field of metal packaging can production, and particularly relates to an automatic conveyor for metal packaging cans. Background Art

[0002] A metal packaging can is a container for packaging items. The metal packaging can has the characteristics of high strength and strong anti-deformation ability, and is mainly used for transportation packaging, outer packaging and commercial packaging. In the production process of metal packaging cans, a series of processes such as slitting, winding and forming, bottom sealing and labeling are required.

[0003] After retrieval, Chinese Patent Publication No. CN114671106B discloses an automatic conveying machine for metal packaging can production, including a bottom frame. A conveyor is installed inside the bottom frame through a regulator. A cleaning plate and a heating plate are slidably connected above the front surface of the bottom frame. Two positioning plates are slidably connected at positions corresponding to the cleaning plate and the heating plate above the rear surface of the bottom frame; with the cooperation of the extrusion mechanism and the clamping mechanism, the cleaning cloth, the sliding block and the rotating assembly of the cleaning plate can be simultaneously close to the surface of the metal packaging can. The surface of the metal packaging can can be cleaned through the cleaning cloth to ensure that air bubbles are generated on the surface of the metal packaging can during labeling. The rotating metal packaging can can be heated through the heating plate so that the adhesive remains sticky when sticking to the surface of the metal packaging can. While the extrusion plate moves downward, the positioning assembly will be inserted into the interior of the metal packaging can. Through the positioning of the positioning assembly, the metal packaging can can be prevented from moving left and right during movement.

[0004] However, in the above technical solution, only the extrusion plate presses down on the metal packaging can to clean the surface of the metal packaging can with the cleaning cloth. However, when the extrusion plate presses down, the metal packaging can will be in a static state, and the cleaning cloth can only clean part of the surface of the metal packaging can. When the metal packaging can moves on the conveyor belt and contacts the bottom frame or other guiding plates, the metal packaging can is likely to rotate, causing the uncleaned part to rotate for pasting labels.
