Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of tobacco grading, and more specifically, relates to a tobacco grading device. Background Art
[0002] The purpose of tobacco grading is to classify tobacco leaves according to their quality and characteristics for their proper use in tobacco production, ensuring the production of high-quality tobacco products. Grading helps to rationally utilize resources, achieve high quality and competitive prices, meet the needs of the cigarette industry, and promote the sustainable development of tobacco production.
[0003] Tobacco grading standards typically include multiple aspects, including appearance quality, internal quality, physical properties, chemical properties, and safety. Appearance quality is the primary basis for grading, and includes factors such as the color, texture, maturity, and uniformity of the tobacco leaves.
[0004] In the actual grading process, manual grading and mechanical grading are often combined to give full play to the advantages of each. Manual grading can accurately identify subtle differences and special qualities of tobacco leaves, while mechanical grading can improve grading efficiency and consistency.
[0005] During manual grading, it is generally necessary to observe the tobacco leaves more closely through illumination. Most of the manual grading tables in the existing technology use desk lamps to increase the light intensity in order to improve the accuracy of manual fine sorting. However, the illumination of the desk lamps is relatively limited and is located above or on the side of the table. Not only is the illumination area small, but it is also easily blocked by the shadows of people at nearby workstations, which can easily affect the selection of tobacco leaves. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.
[0029] like Figure 1-Figure 5 As shown, a tobacco grading device provided in an embodiment of the present application is now described in detail. The tobacco grading device comprises a bottom platform 1, a sorting platform 2 is provided on the top of the bottom platform 1, and a tobacco leaf pre-storage rack 3 is provided on at least one side wall of the bottom platform 1 for temporarily storing tobacco leaves.
[0030] The sorting platform 2 includes a curved plate 21, which is a frosted, translucent plate that ensures uniform and non-glaring light. The curved plate 21 is fixed to the top of the bottom platform 1, and a number of evenly distributed light strips are provided on the inner side of the curved plate 21. A corresponding switch button for controlling the light strips is provided on the bottom platform 1. Sliding grooves 22 are provided on both sides of the curved plate 21, and positioning sliders 23 are provided within the sliding grooves 22. A cleaning structure 24 is provided at the top of the two positioning sliders 23. The cleaning structure 24 can slide back and forth on the upper surface of the curved plate 21 to clean the surface of the curved plate 21, preventing dust from blocking the light and affecting the grading of the tobacco leaves.
[0031] In this embodiment, when manually selecting tobacco leaves, workers place a single or multiple tobacco leaves on the upper surface of the curved plate 21, then smooth the tobacco leaves so that the tobacco leaves are placed flat on the upper surface of the curved plate 21, and turn on the light strip. At this time, the light generated by the light strip passes through the curved plate 21, so that the surface of the curved plate 21 produces uniform light, and illuminates the tobacco leaves, so that the veins and colors of the tobacco leaves are visible to the naked eye, and the differences between multiple tobacco leaves are compared, and tobacco leaves with large color differences are stored in batches inside the tobacco leaf pre-storage rack 3. Since the light passes through the tobacco leaves from bottom to top, it can effectively avoid mutual blocking of light between adjacent sorting platforms 2 and workers blocking light.
[0032] After the current tobacco leaves are sorted and stored in the tobacco leaf pre-storage rack 3, the cleaning structure 24 is manually pulled to slide on the upper surface of the curved plate 21 to remove impurities or dust dropped from the tobacco leaves from the surface of the curved plate 21, so that the curved plate 21 remains clean to prevent foreign matter such as dust or broken leaves from affecting the sorting of the next batch of tobacco leaves.
[0033] In one embodiment, Figure 1-5 As shown, the cleaning structure 24 includes a transverse rod 241, the bottom ends of which are fixedly connected to the top ends of the two positioning sliders 23 respectively. A cavity 242 is provided inside the transverse rod 241, and an air guide 243 is rotatably provided inside the cavity 242. The side walls of the air guide 243 are provided with air outlets 244, and exhaust ports 245 are provided on both sides of the transverse rod 241. When cleaning the upper surface of the curved plate 21, the transverse rod 241 is pulled, so that the transverse rod 241 slides along the upper surface of the curved plate 21 under the influence of the sliding groove 22 and the positioning slider 23. The flowing air is discharged through the air guide 243 and the air outlet 244 to blow away the dust and leaf fragments on the surface of the curved plate 21, causing them to slide along the curved plate 21 until they fall off the curved plate 21, thereby achieving the purpose of cleaning the curved plate 21. In other embodiments, a row of fine brushes may be provided on the lower surface of the transverse rod 241 to remove dust from the upper surface of the curved plate 21 .
[0034] Among them, such as Figure 1-5 As shown, one end of the air guide tube 243 passes through the transverse rod 241 and is provided with a rotating handle 246. The rotating handle 246 is provided to control the direction of the air outlet 244 so that when the curved plate 21 is cleaned, the air outlet 244 is opposite to the exhaust port 245 on the side of the moving direction of the transverse rod 241.
[0035] like Figure 1-5 As shown, a clean air pump 4 is provided inside the bottom machine 1. An exhaust pipe 5 is provided on one side of the clean air pump 4. The end of the exhaust pipe 5 away from the clean air pump 4 passes through the positioning slider 23 and is connected to the air guide pipe 243. Air is exhausted by the clean air pump 4 and then discharged through the exhaust pipe 5 and the air guide pipe 243 to the surface of the curved plate 21, thereby removing foreign matter. The exhaust pipe 5 is rotatably connected to the air guide pipe 243.
[0036] like Figure 1-5As shown, the tobacco leaf pre-storage rack 3 includes an outer frame 31, which is fixedly connected to the base machine 1. The outer frame 31 is internally provided with a plurality of insertion slots 32, and elastic baffles 33 are inserted into the insertion slots 32. The insertion slots 32 are provided with elastic baffles 33, thereby forming multiple cavities within the insertion slots 32 for storing tobacco leaves of different grades. The elastic baffles 33 can be deformed appropriately to facilitate the insertion of tobacco leaves.
[0037] like Figure 1-5 As shown, a receiving chamber 6 is formed at the upper end of the bottom machine 1 and on both sides of the lower end of the curved plate 21. A collection basket 7 is secured within the receiving chamber 6. As dust and leaf debris on the surface of the curved plate 21 slide along and fall off the curved plate 21, they enter the collection basket 7, which collects the dust and tobacco debris, thus preventing clutter in the workshop.
[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
