Description

Technical Field

[0001] The utility model relates to the field of tobacco packaging machinery, in particular to an aluminum foil paper placing device for a tobacco packaging machine. Background Art

[0002] Tobacco packaging machine aluminum foil is a material used in packaging machinery in the tobacco industry. Aluminum foil is made of aluminum and has excellent moisture-proof, oxygen-barrier, light-barrier and heat-insulating properties. In the tobacco production process, aluminum foil is usually used as one of the packaging materials of tobacco packaging machines to wrap cigarettes and protect the quality and freshness of tobacco products.

[0003] The GDX2 tobacco packaging machine and other types of tobacco packaging machines on the market currently have no main power for releasing the aluminum foil. Instead, the aluminum foil is released by pulling the paper feed roller, and the power of the paper feed roller comes from the main machine.

[0004] This paper placing method has a complex mechanical structure, mainly composed of a right paper feeding roller, a left paper feeding roller, a right swing arm, a left swing arm, a right paper tray, a left paper tray, a right paper tray brake, a left paper tray brake, a right swing arm tension spring, a left swing arm tension spring, a right brake compression spring, a left brake compression spring, a right tension adjustment spring, a left tension adjustment spring, a right paper tray brake, and a left paper tray brake. The right paper tray brake or the left paper tray brake is respectively pressed on the right paper tray or the left paper tray by the right tension adjustment spring or the left tension adjustment spring, respectively, to ensure that the paper tray will not rotate too much due to inertia when the right paper feeding roller or the left paper feeding roller stops respectively. However, when the size of the paper roll changes and the rotational inertia of the paper tray changes, the friction force of the braking system cannot change accordingly, thereby causing the right paper feeding roller or the left paper feeding roller to be unstable in conveying the aluminum foil during the start and stop process. If the braking force is adjusted too large, the aluminum foil is easily broken during the start and stop. Therefore, an aluminum foil placing device for a tobacco packaging machine is proposed to solve the above problems. Utility Model Content
