Description

Technical Field

[0001] This utility model relates to the field of tobacco processing and manufacturing equipment technology, and in particular to an online blending and uniform control system for packaged and transported tobacco. Background Technology

[0002] Reconstituted sheet tobacco is generally processed at tobacco sheet tobacco processing units, and then packed and transported to cigarette manufacturing enterprises. Therefore, the packing and transportation process causes the tobacco to be compacted to varying degrees. Generally, during blending, it is directly fed into the blending and metering system via a conveyor belt. The lifting feeder of the blending and metering system has the effect of breaking up the clumps by lifting and tumbling, but the effect is not good, resulting in uneven blending and affecting the taste of the product.

[0003] Therefore, there is an urgent need to design an online blending and uniform control system for packaged and transported tobacco that meets the requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an online blending and uniform control system for packaged and transported tobacco. By adding a lifting and feeding device, a dispersing device, and a high-frequency vibration conveying device before entering the metering system, the system solves the problem of uneven blending and clumping caused by clumping after packaging and transport, and effectively ensures the process quality of the product.

[0021] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0022] Unless otherwise specified, the experimental methods used in the following examples are conventional methods, and the materials and reagents used are commercially available. Unless otherwise specified, the equipment used in the experiments is well known to those skilled in the art.

[0023] A system for online blending and uniform control of packaged and transported tobacco shreds includes: a lifting and feeding device, an air separation device 2, a tobacco shred clumping and dispersing device 3, and a metering system 4. The lifting and feeding device includes a feeding hopper 11 and an elevator 12. The feeding hopper 11 is connected to the inlet end of the elevator 12. The elevator 12 includes an elevator frame 15, a conveyor belt 13, and a feeding roller 14. The conveyor belt 13 is fixed on the elevator frame 15 and has pleats. The feeding roller 14 is fixed on the elevator frame 15 and maintains a preset distance from the bottom of the conveyor belt 13. The feeding roller 14 is equipped with rake nails. The inlet of the air classifier 2 is connected to the outlet end of the elevator 12. The air classifier 2 includes an upper outlet and a lower outlet. The upper outlet is connected to the metering system 4 to transport the loosened, non-clumped tobacco to the metering system 4. The lower outlet is connected to the inlet of the tobacco clump breaking device 3 to transport the loosened, clumped tobacco to the tobacco clump breaking device 3 for further breaking. The outlet of the tobacco clump breaking device is connected to the metering system to transport the further broken tobacco to the metering system 4.

[0024] Furthermore, the lifting frame 15 is connected to the support legs 18, which are fixedly supported on the ground. The feeding roller 14 is connected to the adjusting bolt 16, which is used to adjust the position of the feeding roller 14 on the lifting frame 15. The feeding roller 14 is connected to the feeding reducer 17, which is used to adjust the rotational speed of the feeding roller 14.

[0025] Furthermore, the air separation device 2 includes an air separation chamber and a fan. The air separation chamber is equipped with a partition plate, which divides the air separation chamber into an upper loose tobacco channel and a lower clumped tobacco channel. The upper discharge port is located at the end of the loose tobacco channel, and the lower discharge port is located at the end of the clumped tobacco channel.

[0026] Furthermore, the tobacco shred breaking device 3 is equipped with a spiral rake roller, which is used to break up the clumps of tobacco shreds during operation. Preferably, the tobacco shred breaking device 3 also includes a vibrating screen 31, which is located below the spiral rake roller, and is used to further screen the broken tobacco shreds to ensure the uniformity of the tobacco shreds.

[0027] Furthermore, the metering system 4 includes a metering hopper 41 and a weighing sensor 42. The metering hopper 41 is used to receive and store loose tobacco and broken tobacco, and the weighing sensor 42 is used to monitor the weight of the tobacco in the metering hopper in real time. Specific implementation examples:

[0029] Step 1: The system operation mode is divided into centralized control mode or local mode, which can be flexibly adjusted according to the production mode.

[0030] Step 1: When the boxed tobacco enters the lifting and feeding device, this device is equipped with a conveyor belt with pleats to facilitate the attachment and removal of the tobacco. A feeding roller is installed at a certain distance from the bottom. The installation of the feeding roller is crucial. The height of the feeding roller should be adjustable (for example, lower for stem tobacco and higher for thin or long filaments). The feeding roller has rakes, and the length, shape, and layout of these rakes should be designed reasonably to ensure more frequent contact with the tobacco and facilitate timely rakeing down of any clumps, resulting in a sufficiently good dispersing effect.

[0031] Step 3: After being lifted and fed, the tobacco directly enters the tobacco clumping and breaking device. This device includes an air classifier. Loose tobacco is directly conveyed to the blending and metering system by airflow. Clumped tobacco falls into a chamber with spiral rakes at the bottom of the device. During operation, the spiral rake rollers break up the clumps again, collecting them into the blending and metering system. The spiral breaking device is crucial here; the length, angle, and density of the spiral rakes must be adjustable to suit different types of transported tobacco (storage time, leaf, stem, expanded tobacco).

[0032] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
