Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment, in particular to a tobacco string drawing mechanism for oriental tobacco raw tobacco. Background Art

[0002] Oriental tobacco is a type of sun-cured tobacco. After the mature leaves are harvested, they are strung into bundles, either manually or by a stringing machine. Each bundle is approximately 1.2 meters long and then hung in a curing shed for drying and curing. The finished bundles are then packaged into packs, each weighing approximately 15 kg. Each pack contains approximately 70 bundles. These bundles are then delivered to tobacco purchasing stations and shipped to oriental tobacco processing plants for primary processing.

[0003] The traditional processing model for oriental tobacco involves vacuum conditioning the raw tobacco bales to soften the leaves. The bundles are then manually disassembled, the seam buckles located, and the buckles removed. The seams and thread are then extracted in reverse to separate the tobacco from the cotton thread. Grade and impurity levels are also determined. Currently, string extraction is primarily manual, with an average hourly capacity of 30 kg. Based on a processing capacity of 7,000 kg / hour, at least 240 string extraction workers are required to meet production requirements. This inevitably increases labor costs, results in low labor efficiency, wide variations in string extraction skills, and significant human interference, leading to unstable production flow and reduced yields of crushed tobacco leaves. While string extraction equipment has emerged, it still requires manual feeding and the recovery of tobacco and cotton thread. For example, the Chinese utility model patent for "Automatic String Extraction Mechanism and Machine for Raw Cigarette Strings," published as CN219396221U, aims to further increase processing capacity and reduce labor input, which are key development areas for oriental tobacco companies.

[0004] Therefore, the present application aims to provide a set of automatic tobacco string drawing mechanism to improve the drawing operation rate and reduce the tobacco leaf damage rate. Utility Model Content

[0014] In order to make the technical problems and technical solutions solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0016] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal connections between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0017] like Figures 1 to 3 As shown, a tobacco raw tobacco string extraction mechanism includes a tobacco placing table 1, a string cutting device 2, a string taking-up device 3, a tobacco string separation device 4, a tobacco leaf tangential dropping device 5 and a wind system 6. Among them, the string cutting device 2 and the string taking-up device 3 are existing technologies, and the device has both string cutting and string taking-up functions.

[0018] This application primarily utilizes a device combination design. When used in combination, the combined devices form a complete set of automatic cigarette string extraction units, enabling streamlined cigarette string extraction and significantly improving extraction efficiency. Specifically, the unit comprises: a cigarette platform 1 connected to a conveyor, a string cutting device 2 and a string take-up device 3 mounted on the conveyor, thereby forming a string extraction channel; a cigarette string separation device 4 mounted above the string take-up device 3; the distal end of the cigarette string separation device 4 is connected to the feed inlet of a tobacco leaf tangentially dropping device 5, and the discharge outlet of the tobacco leaf tangentially dropping device 5 is connected to the feed inlet of a pneumatic system 6. The cigarette string separation device 4 includes a second conveyor 401 disposed on either side, with arc-shaped smoke screens 402 disposed on either side of the second conveyor 401. An opening is provided on one side of the middle portion of the second conveyor 401, connected to a negative pressure air duct 403.

[0019] Working principle: When the cigarette string is being drawn out, the cigarette string is first placed on the swinging cigarette table 1, and the conveyor transports the cigarette string to the tangent device 2 to cut the thread end, and then transports it to the take-up device 3 for take-up. The thread end will be fixed and recovered by the cotton thread of the take-up device 3, and the conveyor 2 401 of the cigarette string separation device 4 continues to transport the tobacco leaves forward to the negative pressure air duct 403. Under the action of the negative pressure wind, the tobacco leaves are quickly absorbed into the air duct, thereby being completely separated from the cotton thread. The cotton thread is recovered by the take-up device 3 to the tray below to avoid being entangled in the take-up device. The tobacco leaves are then transported to the tobacco leaf tangential blanking device 5 through the negative pressure air duct 403 for unloading. The unloaded tobacco leaves are then transported to the wind system 6, and the wind system 6 will remove impurities in the tobacco leaves.

[0020] The proposed thread-drawing mechanism has been proven to be capable of assembling the thread of tobacco string sutures on an assembly line, achieving a thread-drawing speed exceeding 5 m / s. This mechanism boasts high efficiency, consistent and orderly operation standards, and effectively reduces tobacco leaf breakage and damage caused by manual thread-drawing, resulting in a high yield rate. The mechanism is simple and easy to operate, making it valuable for widespread application.

[0021] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
