Description

Technical Field

[0001] The utility model 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 becomes increasingly segmented and consumers demand higher quality from their tobacco products, cigarette companies are continuously improving their shredding and processing capabilities to enhance quality, efficiency, and core competitiveness. Cutting is a crucial process in determining tobacco quality, and the functionality and precision of cutting equipment are crucial to ensuring the quality of the processing. Cutters ensure that tobacco has a uniform width and meets cutting quality standards.

[0003] The blade doors of the current shredders used in various cigarette factories all feature a fixed quadrilateral structure, with four sides made of stainless special metal or PE sheeting. This fixed structure relies solely on a chain behind the blade door to drive the tobacco leaves in the shredder's channel forward, pushing them into the working area of the cutter roller for cutting. However, since the blade door's four sides are made of stainless metal or PE sheeting, it cannot be driven by a force other than the leaves behind. This forces the tobacco leaves at the blade door to generate significant friction, which is inconsistent with the friction between the chain and the leaves behind. This leads to inconsistent speed ratios and sheet slippage. When the chain rotates in reverse, the tobacco leaves at the blade door rub against the blade door, and with no driving force, the leaves become stuck in the blade door, causing material blockage. As the cutter roller continues to rotate and cut, it rubs against the blocked, immobile tobacco leaves, generating continuous heat. This ultimately causes the tobacco leaves at the blade door to smolder and smoke, seriously affecting the quality of the shredded product and endangering the health of the equipment.

[0004] Therefore, how to provide a new type of blade door mechanism for a wire cutting machine has become a technical problem that urgently needs to be solved in this field. Utility Model Content
