本发明涉及微波设备技术领域，尤其是烟梗微波膨胀设备技术领域。The invention relates to the technical field of microwave equipment, in particular to the technical field of microwave expansion equipment for tobacco stems.
背景技术Background technique
随着现代烟草工业的飞速发展，烟草制品的安全性和经济性越来越受到人们的关注。烟梗经过处理后得到的膨胀梗丝能有效地降低卷烟制品的焦油含量，提高卷烟制品的安全性；能显著的减少烟梗中的苦味、辣味、刺激性和杂气等，提高卷烟制品的品质；膨胀梗丝具有较高的填充值，将其加入卷烟配方中可以极大的降低成本。因此膨胀梗丝已经大规模地应用于现代卷烟工业中。烟梗微波膨胀技术具有膨胀程度相对高，膨胀均匀性好，烟梗利用率高等优点；烟梗微波膨胀技术以其独特的优越性已逐渐应用于烟草工业。现有专利中重点描述了烟梗微波膨胀处理方法及工艺。中国公开专利CN102326858A、CN202077560U公开了描述了一种滚筒式烟梗连续微波膨胀设备，重点对设备的组成进行了描述。其他领域的微波设备主要采用皮带输送结构，针对烟梗的微波膨胀设备，采用皮带输送，存在烟梗受能极不均匀、膨胀均匀性差及烟梗易打火等不足。With the rapid development of modern tobacco industry, people pay more and more attention to the safety and economy of tobacco products. The expanded shredded stems obtained after the treatment of tobacco stems can effectively reduce the tar content of cigarette products and improve the safety of cigarette products; The quality of expanded cut stems has a high filling value, and adding them to cigarette formula can greatly reduce the cost. Therefore, expanded shredded stems have been widely used in the modern cigarette industry. The microwave expansion technology of tobacco stems has the advantages of relatively high expansion degree, good expansion uniformity, and high utilization rate of tobacco stems; the microwave expansion technology of tobacco stems has been gradually applied in the tobacco industry due to its unique advantages. The existing patent mainly describes the microwave expansion treatment method and technology of tobacco stems. Chinese published patents CN102326858A and CN202077560U disclose and describe a drum-type tobacco stem continuous microwave expansion device, focusing on the description of the composition of the device. Microwave equipment in other fields mainly adopts a belt conveying structure. The microwave expansion equipment for tobacco stems adopts belt conveying, which has disadvantages such as extremely uneven energy receiving of tobacco stems, poor expansion uniformity, and easy ignition of tobacco stems.

The inner cavity of the drum is evenly distributed with copying boards. When working, the conveying device is placed obliquely, with a high feed port and a low discharge port. Under the action of gravity and the copying board, the tobacco stem moves in a three-dimensional approximate helical space in the microwave field. The path is consistent, the energy of the tobacco stem is uniform, and the expansion uniformity is greatly improved. The drum and the copying board are integrally molded and sintered to prevent damage to the drum due to the absorption of smoke oil and smoke. The PTFE material has a large thermal expansion coefficient, so the two ends of the roller and the end cylinder adopt a soft connection of spline groove type.
端筒及连接方条选用不锈钢材料制成。The end barrel and connecting square bars are made of stainless steel.
