Description

Technical Field

[0001] The present invention relates to the technical field of cigarette machinery and equipment, and more specifically, to a novel knife door mechanism of a shredder. Background Art

[0002] As the cigarette market gradually becomes segmented and consumers have higher and higher requirements for the quality of cigarette products, cigarette companies have begun to continuously improve the level of shredding and shredding to achieve the goal of improving quality, increasing efficiency and enhancing core competitiveness. Shredding is an important process that determines the quality of shredded tobacco. The function and precision of shredding equipment are the key to ensuring the quality of shredding. The shredding machine is used to ensure that the shredded tobacco has a uniform width so that it meets the shredded quality standards.

[0003] At present, the cutter blades used by various cigarette factories all adopt a fixed quadrilateral structure, and the four upper, lower, left and right sides are made of stainless special metal or PE plate. This structure is fixed in shape, and only the chain behind the cutter blade drives the tobacco leaves in the cutter body channel forward to push the tobacco leaves in the cutter blade to the working area of ​​the cutter roller for cutting. However, since the four sides of the cutter blade are only stainless metal or PE plate, it is impossible to pass the driving force, and only the power is provided by the tobacco leaves behind. Therefore, the tobacco leaves at the cutter blade have a large friction with the cutter blade, and the friction between the chain behind and the tobacco leaves is inconsistent, which will lead to different speed ratios and the phenomenon of sheet running. When the chain is reversed, the tobacco leaves at the cutter blade rub against the cutter blade, and the cutter blade has no driving force, so the tobacco leaves are stuck at the cutter blade, resulting in material blockage. When the cutter roller continues to rotate and cut, it will rub against the blocked tobacco leaves and continue to generate heat, which eventually causes the tobacco leaves at the cutter blade to smolder and smoke, seriously affecting the quality of the silk products and endangering the health of the equipment.

[0004] Therefore, how to provide a new type of blade door mechanism for a wire cutter has become a technical problem that urgently needs to be solved in this field. Summary of the invention
