Description

Power-off protection mechanism of tobacco bale wrinkle removing device

Technical Field

The utility model relates to the field of tobacco packaging machinery, in particular to a power-off protection mechanism of a tobacco bale wrinkle removing device.

Background

The FOCKE Focke packaging machine is designed, produced and manufactured by Germany FOCKE Focke company, is a special packaging machine for manufacturing cigarette products in cigarette production, is widely used in all national cigarette production factories, and produces tens of millions of boxes of finished cigarette products every year. The FOCKE Fock packaging machine is high in operation speed, the packaging speed of cigarette packets per minute is more than 800, and the machine type designer of the packaging machine designs that in order to prevent the cigarette packets from generating excessive extrusion load in the production and conveying process and avoid the deformation of the cigarette packets, the cigarette packet conveying process route is designed to be a double-channel (double-channel and double-layer cigarette packets) traveling at the same speed, the cigarette packets of the double flues simultaneously enter the transparent paper wrapping process flow of small cigarette packets in the production process, and the packaging of transparent paper is completed.

However, in the production process, as the packaging machine continuously operates every day, mechanical parts can be abraded in different degrees after long-term and long-term operation, so that the tolerance size of a cigarette packet forming flue is increased, variation and gaps are generated, and the cigarette packet is loosened in size and position in the process of wrapping transparent paper to generate wrinkling and unevenness. In addition, the raw and auxiliary materials used in the production of cigarettes in various cigarette factories are different in material quality, for example, the shrinkage rate of the transparent paper is not uniform, the smoothness of the hard small box paper fiber and the surface of the paper of the small box cigarette packet is not uniform, and the quality problems of crease, unevenness and the like after the transparent paper for wrapping the small box cigarette packet is formed can also be caused.

However, the machine set is not provided with an independent device for wrinkle removal treatment on the problems of wrinkling and unevenness of the cellophane generated in the process of wrapping the cellophane paper of the small cigarette packet in the technical process, so that the wrinkle removal device of the cellophane is still blank on the machine type, and the quality defects of wrinkling and unevenness generated in different degrees can be generated on the cellophane paper package of the cigarette packet in the production process. The unsightly wrinkles of the product result in poor satisfaction of the customer on the product, which negatively affects the sale of the product.

The mechanism is a special device for repairing and removing wrinkles in quality defects of wrinkles and unevenness generated after the outer wrapping transparent paper of the cigarette packet is formed in the production process of a FOCKE Fock packaging unit.
