Description

[0001] The invention relates to the technical field of tobacco shred equipment, and in particular to a turnover conveyor and a method for thin slice blending in the tobacco industry. Background Art

[0002] Tobacco silk workshops need to evenly blend the flakes after the slicing process and before the loosening and rehydration process, i.e. between the two key processes, due to the processing requirements of different production brands. At present, in order to ensure the reliability, uniformity and timeliness of the flake blending process, the silk workshop has specially configured 2-3 operators to complete the flake blending process completely in the manual hand-holding mode, that is, relying on 2-3 operators to continuously add and blend the flakes one by one. However, because the blended flakes need to meet the process requirements of uniform addition, the manual blending flake mode cannot efficiently meet the actual uniform blending requirements, which brings certain quality risk hazards to the final product quality; in addition, 2-3 operators need to repeatedly bend and push the flakes manually, and each batch of blending process needs to last for 3-4 hours. According to the production of 3 batches per day, 9-12 hours of work are required per day; this process not only brings great labor intensity and physical harm to the on-site operators, but also the process is very likely to be damaged by the blending flake conveying equipment. The safety risk hazard, that is, the entire manual blending flake process is time-consuming and labor-intensive, labor-intensive, high in safety risks, poor in reliability, and poor in stability. Based on this, the present invention designs a flip conveyor and method for flake blending in the tobacco industry to solve the above-mentioned problems. Summary of the invention
