[0031] The terms “first”, “second”, etc. are only used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0032] In the description of this embodiment, it should be noted that, unless otherwise specified or limited, the terms "disposed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this embodiment based on specific circumstances.

[0033] At present, the relevant national standards stipulate that the placement density of sample boxes should be no less than 1 per 120cm. 2 However, there is no sample box positioning mechanism in the existing oven. When placing the sample boxes, the placement density of the sample boxes depends entirely on manual control, resulting in the placement density of the sample boxes not meeting the requirements, affecting the accuracy of the measurement results and causing large measurement errors.

[0034] In order to solve the above technical problems, the utility model provides a storage rack that can locate the positions of each sample box in the oven so that the placement density of the sample boxes meets the requirements, thereby improving the accuracy of the measurement results of the moisture content of cigarettes.

[0035] In order to make the technical solutions and advantages of the present invention more clear, the implementation methods of the present invention are described in further detail below.

[0036] refer to Figure 1 and Figure 2 The embodiment of the present invention provides a storage rack, including a frame 1 and a partition net 2, the partition net 2 is arranged on the frame 1, and a plurality of limiting grooves 3 are provided on the partition net 2, the limiting grooves 3 are used to place items, and a certain distance is spaced between two adjacent limiting grooves 3.

[0037] When it is necessary to measure the moisture content of cigarettes, the rack 8 provided in this embodiment is first installed in the oven 4, and after weighing the multiple sample boxes 5 containing tobacco samples, the sample boxes 5 are placed in each limiting slot 3 on the rack 8 in sequence. Figure 1 As shown, after the sample is dried, the sample box 5 is weighed again, and the weight of the sample before and after drying is compared to calculate the moisture content of the sample. For example, the distribution density of the limit groove 3 is greater than or equal to 1 / 120cm 2 The present invention facilitates the control of the placement density of the sample box 5 by setting the limiting groove 3, ensuring that the placement density of the sample box 5 meets the requirements, thereby improving the accuracy of the measurement results. Figure 1 As shown, a plurality of racks 8 may be provided in the oven 4 , with each rack 8 being spaced a certain distance apart.

[0038] Optionally, refer to Figure 1 and Figure 2 , the frame 1 is rectangular, and the frame 1 is along the second direction (such as Figure 2 The size of the frame 1 along the first direction (as shown in the Y direction) is larger than that of the frame 1 along the first direction (as shown in the Y direction) Figure 2 The frame 1 is slidably connected to the two inner side walls of the oven 4 on both sides of the frame 1 disposed opposite to each other along the second direction. The frame 1 can move between a first position and a second position along the first direction. The first direction is perpendicular to the second direction. When the frame 1 is in the first position, the frame 1 is completely located in the oven 4, as shown in FIG. Figure 1 When the frame 1 is in the second position, the frame 1 is at least partially outside the oven 4, as shown in FIG. Figure 1 Specifically, refer to the rack 8 at the bottom. Figure 1 and Figure 2 A sliding mechanism is provided on both sides of the frame 1 that are opposite to each other along the second direction. The sliding mechanism includes a slide rail 6 and a slide member 7 extending along the first direction. The slide rail 6 and the slide member 7 are slidably connected. The slide rail 6 is fixedly connected to the inner wall of the oven 4, and the slide member 7 is fixedly connected to the side wall of the frame 1. The slide member 7 can move along the slide rail 6.

[0039] This design makes it easy for the operator to place and remove the sample box 5 from the oven 4. When the sample box 5 needs to be placed in the oven 4, the slider 7 moves along the slide rail 6, moving the frame 1 to the second position so that the sample box 5 can be placed on the rack 8. The frame 1 is then moved to the first position. At this time, the sample box 5 placed on the rack 8 is completely inside the oven 4 and can be dried. When the dried sample needs to be removed from the oven 4, the slider 7 moves along the slide rail 6 and moves the frame 1 to the second position so that the sample box 5 is outside the oven 4 so that the sample box can be removed from the rack 8.

[0040] Optionally, refer to Figure 2 The frame 1 includes two longitudinal bars 11 and a plurality of transverse bars 12. The two longitudinal bars 11 are spaced apart along the second direction, and both longitudinal bars 11 extend along the first direction. A plurality of transverse bars 12 are disposed between the two longitudinal bars 11, and each transverse bar 12 extends along the second direction. One end of the transverse bar 12 is connected to one longitudinal bar 11, and the other end of the transverse bar 12 is connected to another longitudinal bar 11. Each transverse bar 12 is sequentially spaced apart along the first direction. The utility model provides a plurality of transverse bars 12 with gaps between adjacent transverse bars 12. This design allows the sample box 5 placed on the rack 8 to be heated more evenly, thereby avoiding the problem of large errors in the measurement results of the moisture content of the sample due to incomplete drying of the sample.

[0041] Optionally, refer to Figure 2 The partition net 2 includes a plurality of first position-limiting network cable groups and a plurality of second position-limiting network cables 22. The plurality of first position-limiting network cable groups are arranged on the frame 1 at intervals along the second direction. The first position-limiting network cable group includes two first position-limiting network cables 21 arranged at intervals along the second direction. The first position-limiting network cable 21 includes a plurality of straight portions 211 and recessed portions 212 arranged alternately along the first direction. The straight portions 211 extend along the first direction and overlap the crossbar 12. Each recessed portion 212 is located between two adjacent crossbars 12, and the recessed portion 212 protrudes downward from the crossbar 12. Each second position-limiting network cable 22 extends along the first direction and overlaps each crossbar 12. Each group of first position-limiting network cable groups is provided with a second position-limiting network cable 22 on both sides along the second direction. In each group of first position-limiting network cable groups, the recessed portion 212 located between two adjacent crossbars 12 and the two second position-limiting network cables 22 adjacent thereto together form a position-limiting groove 3, as shown Figure 2 The sample boxes 5 are placed in the limiting grooves 3 to position the sample boxes 5 so that the placement density of the sample boxes 5 on the rack 8 meets the requirements.

[0042] Optionally, refer to Figure 2The screen 2 also includes a plurality of third limiting wires 23 spaced apart along the first direction. Each third limiting wire 23 is positioned below the recess 212 and extends along the second direction. Each third limiting wire 23 is sequentially connected to the bottom of each recess 212 spaced apart along the second direction. By positioning the third limiting wires 23 below the recess 212, the present invention further stabilizes the structure of the limiting groove 3, thereby preventing deformation of the limiting groove 3.

[0043] Optionally, the distance between two adjacent second position-limiting wires 22 of each first position-limiting wire group is less than or equal to the maximum dimension of the sample box 5 along the second direction. This dimension design ensures that when the sample box 5 is located in the position-limiting slot 3, it can be stuck between two adjacent second position-limiting wires 22 to prevent the sample box 5 from loosening and causing it to topple or fall out of the position-limiting slot 3.

[0044] Optionally, the frame 1 and the partition 2 are made of metal. Metal has good high temperature resistance and can extend the service life of the storage rack 8.
