Description

Technical Field

[0001] The utility model relates to the technical field of tobacco moisture content detection, and particularly relates to a sample box. Background Art

[0002] In the process of cigarette production and manufacturing, the moisture content of in-process products is a key indicator. The level of moisture content has a significant impact on the burning quality of cigarettes. Moreover, the moisture content of cut tobacco is an important factor affecting the moisture content and low-molecular volatile components of cigarette smoke, and even the sensory quality. In addition, the moisture content of cut tobacco has a significant impact on its physical properties such as color, toughness, combustibility, aroma, and taste. Therefore, accurately detecting the moisture content of in-process products is crucial for ensuring product quality.

[0003] In the prior art, sample boxes are generally used to hold cut tobacco samples for detecting the moisture content of cut tobacco. The sample box includes a box body and a box cover that is buckled on the box body. The box cover can be removed from the box body so that the operator can take and place the cut tobacco. However, inaccurate detection results often occur in the current detection of the moisture content of cut tobacco. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of inaccurate detection results in the current detection of the moisture content of cut tobacco. The utility model provides a sample box, which can improve the accuracy of the detection results of the moisture content of cut tobacco.

[0005] To solve the problem of inaccurate detection results of the moisture content of cut tobacco, an embodiment of the utility model discloses a sample box, including: a box body, which has a cavity inside, an opening is provided above the box body, and the cavity is communicated with the opening; a box cover, which can be buckled on the opening or separated from the opening; a connecting member, which is arranged between the box body and the box cover. When the box cover is separated from the box body, the box cover is connected to the box body through the connecting member.

[0006] By adopting the above technical solution, through the setting of the connecting member, when the box cover is separated from the box body, the box cover can also be connected to the box body through the connecting member, so as to avoid the problem of incorrect detection results caused by miscovering the box cover (that is, the box cover of sample box A is covered on sample box B), thereby improving the accuracy of the detection results.

[0007] Further, the connecting member includes a first connecting piece and a second connecting piece. The first end of the first connecting piece is hinged to the box cover, the second end of the first connecting piece is hinged to the first end of the second connecting piece, and the second end of the second connecting piece is hinged to the box body.

[0008] Further, the sample box provided by the present application further includes a first connecting seat and a second connecting seat. Among them, a first connecting seat protruding from the side wall of the lid is provided on the lid, and a second connecting seat protruding from the side wall of the box body is provided on the box body. The first end of the first connecting piece is hinged to the first connecting seat, and the second end of the second connecting piece is hinged to the second connecting seat.

[0009] With the above technical solution, by setting the hinge connection, the first connecting piece and the second connecting piece can rotate freely at the hinge, improving the movement range and flexibility of the lid during the process of opening and closing the lid, thereby facilitating the operator to open or close the lid.

[0010] Further, the first connecting seat is welded to the lid, and the second connecting seat is welded to the box body.

[0011] With the above technical solution, by using the welding method to fix the first connecting seat and the second connecting seat to the box body and the lid respectively, it is possible to avoid punching holes in the box body and the lid, which may cause damage to the box body and the lid, thereby ensuring that the sample box has good airtightness and does not affect the normal use of the sample box.

[0012] Further, the number of the connecting pieces, the first connecting seats and the second connecting seats is two. One of the connecting pieces and the corresponding first connecting seat and second connecting seat are arranged on one side of the box body, and the other connecting piece and the corresponding first connecting seat and second connecting seat are symmetrically arranged on one side of the box body.

[0013] Further, at least part of the first connecting piece and the second connecting piece are curved.

[0014] With the above technical solution, by using the first connecting piece and the second connecting piece that are at least partially curved, it is possible to avoid the situation of straight-line locking of the connecting piece during the process of opening or closing the lid. In addition, in the case of high temperature, the curved structure can provide a certain compensation space to avoid the situation of locking of the connecting piece caused by the thermal expansion of the connecting piece material, ensuring the smoothness of the connecting piece during the opening and closing process.

[0015] Further, both the box body and the lid are cylinders.

[0016] Further, the diameter of the lid is larger than the diameter of the box body, and a circular cavity is provided at the bottom of the lid. When the lid can be buckled on the box body, the inner surface of the lid and the cavity enclose a sealed cavity.

[0017] Further, the connecting pieces, the first connecting seats and the second connecting seats are all made of metal materials.

[0018] Further, both the first connecting seat and the second connecting seat are provided with threaded holes, and through holes are provided at the first end of the first connecting seat and the second end of the second connecting piece. The sample box further includes a first bolt and a second bolt. The first bolt passes through the through hole on the first connecting piece and is threadedly connected to the threaded hole on the first connecting seat, so that the first connecting piece is hinged to the second connecting seat; the second bolt passes through the through hole on the second connecting piece and is threadedly connected to the threaded hole on the second connecting seat, so that the second connecting piece is hinged to the second connecting seat.

[0019] With the above technical solution, through bolt connection, the operator can adjust the locking degree of the bolt to achieve the purpose of adjusting the moving resistance of the connecting piece, making the opening and closing of the box cover and the box body smooth and labor-saving.

[0029] To make the purpose, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings.

[0030] For the test of tobacco moisture content, in addition to the on-line moisture detector, there is also a more accurate method, namely the oven test method. This method has high precision and high stability and is often used as the final judgment basis for the moisture content of cigarettes in production, which has great guiding significance for the production process.

[0031] In the actual test process, after the sample preparation is completed, the basic steps for testing the moisture content of cigarettes in production using the oven method are as follows:

[0032] 1. Preparation stage:

[0033] (1) Turn on the power of the oven and preheat the oven to (100 ± 2) °C.

[0034] (2) Open the lid of the sample box, put the lid and the box body into the oven for forced-air drying for 30 minutes, take out the box body of the sample box, cover the lid, put it into the desiccator, cool it to room temperature, weigh the sample box and record it, accurate to 0.001 g.

[0035] (3) Open the lid of the sample box, put the sample to be tested into the sample box, cover the upper lid, weigh it and record it, accurate to 0.001 g.

[0036] 2. Testing stage:

[0037] (1) Open the lid of the sample box containing the sample to be tested, put the lid and the box body into the oven together and close the oven door. Start timing after the temperature stabilizes at (100 ± 1) °C. After 2 hours, take out the box body of the sample box, close the lid and put it into the desiccator. Weigh the sample box after cooling to room temperature and record it accurately to 0.001 g.

[0038] (2) Calculate the moisture content of the test sample according to the formula: Moisture content = (weight of the sample before drying - weight of the sample after drying) ÷ weight of the sample before drying × 100%.

[0039] In the prior art, sample boxes are generally used to hold tobacco samples to detect the moisture content of tobacco. The sample box includes a box body and a lid that is buckled on the box body. The lid can be removed from the box body so that the operator can take and place the tobacco. However, at present, the detection of the moisture content of tobacco often has the problem of inaccurate detection results.

[0040] Through the exploration of the inventor, it is found that the main reason for the inaccurate detection results of the moisture content of tobacco at present is that during the whole test process, the lid needs to be opened and closed many times. In the prior art, the lid and the box body are completely separated, and there is a risk of miscovering the lid during the measurement process (that is, the lid of sample box A is covered on sample box B). In the oven method test, the measurement accuracy of the weight is required to be accurate to 0.001 g, and the accuracy requirement is very high. Due to the influence of factors such as processing and manufacturing and daily use wear, the weights of different sample box lids are not the same. Therefore, after miscovering the lid of the sample box, it will directly affect the accuracy of the measurement result, and then lead to an incorrect guidance for the judgment of the cigarette production and manufacturing process and product quality.

[0041] To solve the problem of inaccurate detection results of the moisture content of tobacco, an embodiment of the present utility model discloses a sample box. Referring to Figure 1 and Figure 2 , the sample box provided by the present utility model includes: a box body 1, a lid 2 and a connecting member 3. Among them, a cavity is provided inside the box body 1, and an opening is provided above the box body 1, and the cavity is communicated with the opening. The lid 2 can be buckled on the opening or separated from the opening. The connecting member 3 is provided between the box body 1 and the lid 2. When the lid 2 is separated from the box body 1, the lid 2 is connected to the box body 1 through the connecting member 3.

[0042] By adopting the above technical solution, by setting the connecting member 3, when the lid 2 is separated from the box body 1, the lid 2 can also be connected to the box body 1 through the connecting member 3, so as to avoid the detection result error caused by miscovering the lid 2 (that is, the lid 2 of sample box A is covered on sample box B), and then improve the accuracy of the detection result.

[0043] Further, referring to Figure 1 and Figure 3, the connecting member 3 includes a first connecting piece 31 and a second connecting piece 32. The first end of the first connecting piece 31 is hinged to the box cover 2, the second end of the first connecting piece 31 is hinged to the first end of the second connecting piece 32, and the second end of the second connecting piece 32 is hinged to the box body 1.

[0044] With the above technical solution, by setting the hinge connection, the first connecting piece 31 and the second connecting piece 32 can rotate freely at the hinge, improving the range of motion and flexibility of the box cover 2 during the process of opening and closing the cover, thus facilitating the operator to open or close the box cover 2.

[0045] Furthermore, referring to Figure 1 and Figure 3 , the sample box provided by the present utility model further includes a first connecting seat 4 and a second connecting seat 5. Among them, a first connecting seat 4 protruding from the side wall of the box cover 2 is provided on the box cover 2, and a second connecting seat 5 protruding from the side wall of the box body 1 is provided on the box body 1. The first end of the first connecting piece 31 is hinged to the first connecting seat 4, and the second end of the second connecting piece 32 is hinged to the second connecting seat 5.

[0046] Furthermore, the first connecting seat 4 is welded to the box cover 2, and the second connecting seat 5 is welded to the box body 1.

[0047] With the above technical solution, by using the welding method to fix the first connecting seat 4 and the second connecting seat 5 to the box body 1 and the box cover 2 respectively, it is possible to avoid punching holes in the box body 1 and the box cover 2, which may cause damage to the box body 1 and the box cover 2, thus ensuring that the sample box has good airtightness and does not affect the normal use of the sample box.

[0048] Furthermore, as Figure 3 shown, the number of the connecting member 3, the first connecting seat 4 and the second connecting seat 5 is two. One connecting member 3 and the corresponding first connecting seat 4 and second connecting seat 5 are provided on one side of the box body 1, and the other connecting member 3 and the corresponding first connecting seat 4 and second connecting seat 5 are symmetrically provided on one side of the box body 1. By providing one connecting member 3 on each side of the box body 1 in this application, the force on the box cover 2 during opening and closing can be made uniform, thus avoiding damage to the device.

[0049] Furthermore, both the first connecting piece 31 and the second connecting piece 32 are at least partially curved. Exemplarily, the width of the connecting member can be 6 mm and the thickness can be 1.25 mm.

[0050] With the above technical solution, by using the first connecting piece 31 and the second connecting piece 32 that are at least partially curved, the situation of linear locking of the connecting piece 3 during the process of opening or closing the box cover 2 can be avoided. In addition, in the case of high temperature, the curved structure can provide a certain compensation space to avoid the occurrence of locking of the connecting piece 3 caused by the thermal expansion of the material of the connecting piece 3, ensuring the smoothness of the connecting piece 3 during the opening and closing processes.

[0051] Further, both the box body 1 and the box cover 2 are cylinders. The diameter of the box cover 2 is larger than that of the box body 1, and a circular cavity is provided at the bottom of the box cover 2. When the box cover 2 can be buckled on the box body 1, the opening at the upper end of the box body 1 is inserted into the circular hole cavity at the bottom of the box cover 2, and the inner surface of the box cover 2 and the cavity of the box body 1 enclose a sealed cavity. Exemplarily, the outer diameter of the box body 1 can be 70 mm, the height of the box body 1 can be 35 mm, and the wall thickness of the box body 1 can be 1 mm. The outer diameter of the box cover 2 can be 72 mm, the height of the box cover 2 can be 9 mm, and the wall thickness of the box cover 2 can be 1 mm.

[0052] Further, the connecting piece 3, the first connecting seat 4, and the second connecting seat 5 are all made of metal materials.

[0053] Further, the first connecting seat 4 and the second connecting seat 5 are both provided with threaded holes, through holes are provided at the first end of the first connecting seat 4 and the second end of the second connecting piece 32, and the sample box further includes a first bolt 6 and a second bolt 7. The first bolt 6 passes through the through hole on the first connecting piece 31 and is threadedly connected to the threaded hole on the first connecting seat 4, so that the first connecting piece 31 is hinged to the second connecting seat 5; the second bolt 7 passes through the through hole on the second connecting piece 32 and is threadedly connected to the threaded hole on the second connecting seat 5, so that the second connecting piece 32 is hinged to the second connecting seat 5.

[0054] With the above technical solution, through bolt connection, the operator can adjust the moving resistance of the connecting piece 3 by adjusting the locking degree of the bolts. That is to say, the operator can adjust the locking degree of the bolts by rotating the first bolt 6 and the second bolt 7. When the locking degrees of the first bolt 6 and the second bolt 7 are increased, the rotational resistance of the first connecting piece 31 and the second connecting piece 32 will increase accordingly, and at this time, the connection between the first connecting piece 31 and the second connecting piece 32 is also relatively firm. When the first bolt 6 and the second bolt 7 are loosened, the rotational resistance of the first connecting piece 31 and the second connecting piece 32 will decrease accordingly, and at this time, the rotation of the first connecting piece 31 and the second connecting piece 32 will be relatively smooth. In practical applications, the operator can adjust the locking degrees of the first bolt 6 and the second bolt 7 according to the actual situation, so that the first connecting piece 31 and the second connecting piece 32 can rotate smoothly while the connection is firm.

[0055] In this application, by providing a connecting member 3 between the box body 1 and the box cover 2, the box body 1 and the box cover 2 of the sample box can be kept connected throughout the moisture content testing process. When there are a large number of samples to be tested and multiple sample boxes are involved in the moisture content detection simultaneously, the situation of misplacing the box cover will not occur, thus ensuring the accuracy of the moisture content detection result.

[0056] Although the present invention has been illustrated and described by referring to some preferred embodiments thereof, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Those skilled in the art can make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
