Description

Technical Field

[0001] The utility model relates to the technical field of tobacco shred detection, in particular to a highly sealed sample box. Background Art

[0002] The moisture content of cut tobacco refers to the degree of moisture in the cut tobacco, which is usually called water content. It is expressed as a percentage and is numerically equal to the ratio of the mass of the water content of the cut tobacco to the mass of the cut tobacco. In the process of cigarette production, the moisture content of cut tobacco affects the anti-breakage performance of the cut tobacco during the rolling process. A low moisture content will reduce the anti-breakage performance, thereby increasing the empty rate and scrap rate during the rolling process. Therefore, in the process of making cut tobacco, the moisture content of the cut tobacco needs to be tested to control the quality of the cigarette.

[0003] When testing the moisture content of tobacco, firstly, the processed tobacco is sampled and stored in a sample box, then transferred to the testing station, and the sample box is placed in an oven or other equipment to test the moisture content of the sample tobacco. The existing sample box usually consists of a box body and a box cover, and the box cover can be directly covered on the box body.

[0004] The matching mode between the box body and the box cover of the existing sample box is relatively simple, resulting in poor sealing performance of the sample box, causing the sample tobacco to be easily affected by moisture in the air during storage and testing, resulting in a high error in the moisture content test results of the tobacco. Summary of the invention

[0030] like Figure 1-Figure 4As shown, the embodiment of the present application provides a high-sealing sample box, which mainly includes a box body 100, a box cover 200, a mounting plate 300, a butt plate 400, a spring 500 and a first sealing ring 600. Among them, the box cover 200 is detachably mounted on the open end of the box body 100. The mounting plate 300 and the butt plate 400 are both configured as circular plates, the mounting plate 300 is mounted in the box cover 200, the butt plate 400 is slidably mounted on the mounting plate 300 along the axial direction of the box cover 200, and the spring 500 is mounted between the mounting plate 300 and the butt plate 400. The first sealing ring 600 is made of rubber material, and the first sealing ring 600 is fixed on the butt plate 400. When the box cover 200 is installed to the open end of the box body 100, the abutment plate 400 and the first sealing ring 600 are resisted by the open end of the box body 100, and can move toward the mounting plate 300 and compress the spring 500. Under the elastic force of the spring 500, the first sealing ring 600 can be squeezed between the abutment plate 400 and the open end of the box cover 200, thereby sealing the sample box, reducing the influence of moisture in the air on the sample tobacco during storage and testing, and reducing the error of the tobacco moisture content test results.

[0031] In this embodiment, an annular groove 110 is provided at the open end of the box body 100, and a second sealing ring 700 is installed in the annular groove 110. The second sealing ring 700 is made of rubber material. An annular plate 410 adapted to the annular groove 110 is installed on the abutment plate 400. When the box cover 200 is installed to the open end of the box body 100, the annular plate 410 can enter the annular groove 110 and abut against the second sealing ring 700. Through such an arrangement, the second sealing ring 700 and the first sealing ring 600 cooperate with each other to form a two-level seal between the box body 100 and the box cover 200, thereby further improving the sealing performance of the sample box.

[0032] In this embodiment, two symmetrically arranged guide rods 310 are fixed on the mounting plate 300, and the axial direction of the guide rods 310 is parallel to the axial direction of the box cover 200. The abutment plate 400 is provided with holes adapted to the guide rods 310, and the guide rods 310 pass through the holes adapted thereto. Through the mutual cooperation between the guide rods 310 and the holes, the abutment plate 400 is slidably mounted on the mounting plate 300 along the axial direction of the box cover 200. In addition, a sealing filler can be arranged on the inner wall of the hole to seal the gap between the guide rods 310 and the hole.

[0033] In this embodiment, the number of springs 500 is the same as the number of guide rods 310 and corresponds one to one, that is, two springs 500 are provided. The spring 500 is sleeved on the corresponding guide rod 310, and one end of the spring 500 is fixed on the mounting plate 300, and the other end is fixed on the abutment plate 400. This arrangement facilitates the installation of the spring 500.

[0034] In this embodiment, the sample box also includes a mounting bolt 800, one end of the nut of the mounting bolt 800 is located outside the box cover 200, one end of the screw rod of the mounting bolt 800 passes through the box cover 200 and the mounting plate 300, and is threadedly connected with a nut 810. The box cover 200 and the mounting plate 300 are provided with holes for the mounting bolt to pass through, and the gaps between the two holes are filled with sealant. This arrangement makes it easy to install the mounting plate 300 on the box cover 200. In addition, the mounting plate 300 can also be glued to the box cover 200.

[0035] In this embodiment, a connection assembly is provided between the box body 100 and the box cover 200, and the box cover 200 is detachably mounted on the open end of the box body 100 through the connection assembly. By providing the connection assembly, the cooperation between the box body 100 and the box cover 200 is facilitated.

[0036] In this embodiment, the connection assembly includes a card slot 120 and a card block 210 that cooperate with each other. Among them, the card block 210 is fixed on the inner side wall of the box cover 200. The card slot 120 is arranged on the outer side wall of the open end of the box body 100, and the card slot 120 mainly includes a guide slot 121, a connecting slot 122 and a fixed slot 123. The connecting slot 122 connects the guide slot 121 and the fixed slot 123, and the card block 210 can enter the guide slot 121 and enter the fixed slot 123 along the guide slot 121 and the connecting slot 122.

[0037] By adopting the above technical solution, when the box cover 200 is installed to the open end of the box body 100, first align the block 210 with the guide groove 121 so that the block 210 enters the guide groove 121, and then press the box cover 200 downward to move the block 210 along the guide groove 121 to the end of the guide groove 121. At this time, the spring 500 will be compressed; then rotate the box cover 200 relative to the box body 100 so that the block 210 enters the fixed groove 123 along the connecting groove 122. Under the elastic force of the spring 500, the block 210 can be kept in the fixed groove 123, so that the box body 100 and the cover body are relatively fixed. When the box cover 200 needs to be removed, the box cover 200 can be pressed downward to move the block 210 along the fixing groove 123 to the end of the fixing groove 123; then the box cover 200 is rotated relative to the box body 100 so that the block 210 enters the guide groove 121 along the connecting groove 122, and the box cover 200 can be separated from the box body 100.

[0038] In addition, the number of connecting components in this embodiment can be set to two or more groups, so that the box cover 200 and the box body 100 can be matched more stably.

[0039] In another embodiment, the connecting assembly includes an internal thread and an external thread that cooperate with each other, wherein the internal thread is arranged on the inner side wall of the box cover 200, and the external thread is arranged on the outer side wall of the open end of the box cover 200. Through the cooperation between the internal thread and the external thread, the box cover 200 is threadedly connected to the box body 100.
