Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco packing, and in particular relates to a tobacco packing mechanism for alternately stacking and compacting double boxes. Background Art

[0002] Tobacco redrying is a process to improve the quality of tobacco leaves. It changes the chemical composition of tobacco leaves by reheating them, thereby improving the color, aroma and taste of tobacco leaves. The process of tobacco redrying is divided into three stages: preheating, main roasting and cooling. The preheating stage is to gradually increase the temperature of tobacco leaves, eliminate moisture and impurities, and prepare for main roasting. The main roasting stage is the core of redrying. It promotes the conversion of sugar, nicotine and other organic matter in tobacco leaves by controlling temperature, humidity and time, and improves the aroma and sweetness of tobacco leaves. The cooling stage is to reduce the temperature of tobacco leaves, prevent excessive oxidation and discoloration, and maintain the stability and quality of tobacco leaves.

[0003] Tobacco packing is an important part of the tobacco production process, which involves the quality, storage and transportation of tobacco leaves. The purpose of tobacco packing is to maintain the moisture, color and aroma of tobacco leaves, and to prevent tobacco leaves from being damaged, mildewed and contaminated. The requirements for tobacco packing are to ensure the quality and safety of tobacco leaves and avoid damage or deterioration during transportation and storage. Tobacco leaves should be packed in a dry, ventilated and clean environment to avoid mixing with harmful substances or odorous items. Tobacco leaves should be stacked flat and tightly in the box without gaps or looseness. The weight of tobacco leaves in each box should be similar and should not exceed the maximum limit specified. The existing tobacco sorting and packing is to transport tobacco leaves to the top of the tobacco frame and then naturally fall into the tobacco frame, but the position of the tobacco frame and the conveying device is fixed, resulting in the tobacco leaves being stacked in a cone shape on the conveyor belt of the material-stacking device in the tobacco frame, and the entire tobacco frame cannot be filled. In addition, the tobacco leaves are fluffy and the stacking is relatively loose, with low space utilization. The manual stacking process easily leads to the generation of broken tobacco leaves, and a large amount of manpower is required to compact and pack the tobacco leaves.

[0004] Therefore, it is very necessary to develop a tobacco packing mechanism with double boxes for alternating stacking and compacting. Utility Model Content
