[0001] The present application relates to the technical field of tobacco shredders for shredding equipment, and in particular to an intelligent control system for shredders based on edge computing technology. Background Art

[0002] The tobacco cutter is an important equipment on the production line of the tobacco factory's tobacco making workshop. It is used to cut tobacco leaves or stems into tobacco shreds of equal width to meet subsequent processing requirements.

[0003] When the shredder is working, loose materials such as tobacco leaves or tobacco stems with a certain flow rate enter a wedge-shaped channel composed of upper and lower conveyor chains through the feeding device. The upper and lower chains move to convey and squeeze the materials, so that they gradually form a tightly structured "tobacco cake" and are sent to the rectangular knife gate at the front end of the channel. The main motor drives the knife roller to rotate along the knife gate through a synchronous toothed belt. The speed of the knife roller and the speed of the chain are controlled by the programmable controller PLC to maintain a strict proportional operation. The eight or ten blades on the knife roller are controlled by the electric feed system to make feeding movements, and the pusher device is continuously fed quantitatively, and the knife is reciprocated by the sharpener to form a cutting cylinder with a specified diameter and sharp edge. The "tobacco cake" continuously sent from the knife gate is cut into tobacco of the required width and sent out from the drop hopper.

[0004] At present, the operation of the wire cutter has been realized by the automatic operation controlled by the programmable controller PLC. At the same time, the wire cutter can run the wire cutting according to the parameter indicators of the wire cutter issued by the central control system of the wire production line, meeting the requirements of production process indicators such as wire cutting width for different production batches.
