Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco leaf grading sample display racks, in particular to a tobacco leaf grading sample display rack. Background Art

[0002] Tobacco is an annual or limited perennial herb, a plant of the Solanaceae family. It is the basic raw material for tobacco products such as cigarettes, cigars, shredded tobacco, and redried tobacco. The tobacco involved in this patent mainly refers to flue-cured tobacco. After the initial curing of flue-cured tobacco leaves, they need to be graded and rated in accordance with standard regulations or industrial needs. In particular, through the rating of tobacco leaves, producers can better understand the quality and characteristics of tobacco leaves, so as to better achieve high-quality and high-price purchase and allocation, while ensuring the income of tobacco farmers, continuously and stably providing high-quality cigarette raw materials, meeting the demand for industrial raw materials, ensuring the stability of brand raw material style characteristics, and improving the quality and market competitiveness of cigarette products.

[0003] At present, during the tobacco leaf purchase process, graders will arrange the graded tobacco leaves in order according to the grade basket samples. The graders rely on visual and tactile senses to judge and grade each basket. Tobacco leaf grading requires the tobacco leaves to be evaluated from the overall appearance, according to the grade factors such as maturity, leaf structure, identity, oil content, color, length, damage, moisture, and acceptance rules. If the sample is not made in a standard way, the grade factors of the physical object are not understood accurately, and the visual and tactile senses of the graders are not accurate, the rating will be greatly deviated. It is difficult to grade the handover parts and special tobacco leaves, resulting in a large number of tobacco leaves rework and low purchase efficiency. Secondly, the appearance quality of the samples cannot be displayed in multiple dimensions, and it is not easy to judge the length of the tobacco leaves and distinguish the tolerance of the tobacco leaf grades, resulting in inaccurate sample purchases and unstable purchase vision. At the same time, it is difficult to replace and preserve the samples. Utility Model Content

[0025] As attached Figure 1 To Attachment Figure 6 As shown:

[0026] Embodiment 1: The utility model provides a tobacco leaf sample display rack for grading samples, including a placement mechanism 100 and a limiting mechanism 200, which includes a support table 101, a plurality of support frames 102 are evenly fixedly installed on the upper end of the support table 101, a placement platform 103 is fixedly installed at the front end of the support frame 102, sliders 105 are slidably installed on both sides of the placement platform 103, a measuring ruler 106 is slidably connected inside the slider 105, and the measuring ruler 106 is in contact with the placement platform 103.

[0027] The placement mechanism 100 further includes a measuring scale 104 disposed on the upper end of the placement platform 103 .

[0028] A recording board bracket 107 is fixedly mounted on one side of the support frame 102 , and a limiting slot 108 is provided at the upper end of the recording board bracket 107 .

[0030] The limiting mechanism 200 includes a bottom groove 201 arranged at the upper end of the placing table 103, a bottom clamp 202 is fixedly installed at the front end of the bottom groove 201, a plurality of springs 203 are fixedly installed at the lower end inside the bottom groove 201, an upper clamp 204 is slidably connected inside the bottom groove 201, the plurality of springs 203 are fixedly connected to the upper clamp 204, a plurality of anti-slip strips are arranged at the lower end of the upper clamp 204 and the upper end of the bottom clamp 202, and the lower end of the upper clamp 204 is in contact with the upper end of the bottom clamp 202.

[0031] As can be seen from the above, before rating, the staff will place the control tobacco leaf samples on the placement table 103. When placing, the staff can pull the upper clamping plate 204 to make the upper clamping plate 204 slide upward inside the bottom groove 201, the spring 203 is stretched, the upper clamping plate 204 is separated from the bottom clamping plate 202, and the root of the tobacco leaf is placed on the bottom clamping plate 202. The pull on the upper clamping plate 204 is released. Under the action of the spring 203, the upper clamping plate 204 contacts the bottom clamping plate 202 again, so as to clamp and fix the root of the tobacco leaf. The bottom clamping plate 202 and the upper clamping plate 204 are both provided with a plurality of anti-slip strips to prevent the tobacco leaf from sliding. The staff then spreads the tobacco leaf flat and pulls the measuring plate upward. After measuring the ruler 106, slide the measuring ruler 106, make the slider 105 slide inside the placement table 103, move the measuring ruler 106 to the front end of the tobacco leaf, release the pull on the measuring ruler 106, and under the action of gravity, the measuring ruler 106 drops to press the tobacco leaf, so that the tobacco leaf can be kept flat and fixed, and the measuring scale 104 and the measuring ruler 106 are measured so that the grader can quickly compare the similarities and differences between the real object and the sample, and determine the real object grade according to the appearance quality of the sample, so as to achieve accurate sample purchase. After placing the sample, write the location and appearance characteristics of the tobacco leaf grade on the card, and insert the card into the identification card slot 111, so that the staff can distinguish the tobacco leaves sold by tobacco farmers during the rating process and record the appearance characteristics of different types of tobacco leaves.

[0032] When grading tobacco leaves, the grading record card can be inserted into the limiting slot 108 and placed on the record board bracket 107 to support the record card.

[0033] The spotlight 109 provides light for sample display so that the staff can observe the leaf surface appearance characteristics such as the position, color, maturity, etc. of the tobacco leaves at any time, thereby improving the accuracy of tobacco leaf sample rating.

[0034] By setting up a plurality of universal wheels 110, it is convenient to move the tobacco leaf grading sample display rack.
