[0022] By providing an oven bracket for measuring the moisture content of cigarettes in the embodiment of the present application, it effectively solves the problems of the number of sample boxes measured, the placement position of the sample boxes, and the fact that the sample boxes placed by the inspectors do not meet the requirement that the density of sample boxes is not less than 1 per 120 cm 2According to the requirements, the above factors will all affect the thermal field stability in the oven, thereby causing differences in moisture measurement. This device can significantly reduce the differences in moisture measurement results caused by different numbers and placement positions of sample boxes, thereby significantly improving the accuracy of measurement results; it is arranged in the form of equidistant grids horizontally and vertically, which can not only maintain the consistency and stability of the thermal field at each point in space, but also has a simple structure, low cost, and is easy to implement; on the basis of meeting the national standard requirement that the density of sample boxes is not less than 1 per 120 cm 2 , reasonably divide the area to maximize the number of sample boxes measured at one time and ensure the detection ability of the oven.
[0023] Such as Figure 1 and Figure 2 shown, the technical solution in the embodiment of the present application effectively solves the technical problem that on the basis of meeting the qualified oven temperature measurement, the number of sample boxes measured, the placement position of the sample boxes, and the placement of the sample boxes by the inspector do not meet the requirement that the density of sample boxes is not less than 1 per 120 cm 2 , and the above factors will all affect the thermal field stability in the oven, thereby causing differences in moisture measurement. The general idea is as follows: An oven bracket for measuring the moisture of cigarettes includes two vertically placed and parallel brackets 11 and a bracket. The bracket includes a horizontal connecting rod 12 and a vertical connecting rod 13. The horizontal connecting rod 12 is evenly and equidistantly fixedly installed on the bracket 11, and the vertical connecting rod 13 is evenly and equidistantly fixedly installed on the horizontal connecting rod 12. A plurality of positioning pieces 14 are evenly and equidistantly fixedly installed on the vertical connecting rods 13. The positioning pieces 14 are arranged horizontally and vertically evenly with the bracket as the center. The center distance of the positioning pieces 14 is 12 cm. The positioning pieces 14 are made of aluminum alloy, and the thickness is preferably 0.5 mm to reduce its influence on the heat conduction and heat exchange of the sample box. The positioning pieces 14 are solid round pieces to achieve the consistency of the thermal field when measuring the maximum number of sample boxes. The diameter of the positioning pieces 14 is slightly smaller than the diameter of the sample box (64 mm), preferably 60 mm, to reduce the influence of the positioning pieces 14 on the sample box. The positioning pieces 14 and the vertical connecting rods 13 are adhered by high-temperature resistant glue to reduce the influence of introduced substances on the thermal field; on the premise of meeting the requirement that the density of sample boxes is not less than 1 per 120 cm 2 , install the positioning pieces 14 according to the rules of equidistant distribution longitudinally and horizontally and symmetry about the center point, the upper and lower central axes, and the left and right central axes to reduce the thermal field difference at each point caused by the introduction of the positioning pieces 14 and improve the consistency and stability of the thermal field. Fix the positioning pieces 14 on the basic bracket. Whether there is a sample box on the positioning pieces 14 or not, the consistency and stability of the up and down circulating thermal field can be maintained. When measuring the moisture of cigarettes, the sample box only needs to be placed on the positioning pieces 14 and dried according to the requirements. This bracket can ensure the stability of the circulating hot air from top to bottom and from bottom to top, and significantly improve the moisture stability at each positioning point.
[0024] In view of the problems existing in the prior art, the utility model provides an oven bracket for measuring the moisture content of cigarettes. This device can significantly reduce the differences in moisture measurement results caused by different numbers and placement positions of sample boxes, thereby significantly improving the accuracy of measurement results; it is arranged in the form of equidistant grids horizontally and vertically, which can not only maintain the consistency and stability of the thermal field at each point in space, but also has a simple structure, low cost, and is easy to implement; on the basis of meeting the requirement that the density of sample boxes in the national standard is not less than 1 per 120 cm 2 , the area is reasonably divided to maximize the number of sample boxes measured at one time and ensure the detection ability of the oven.
[0025] Working principle:
[0026] First step, on the premise of meeting the requirement that the density of sample boxes is not less than 1 per 120 cm 2 , the positioning pieces 14 are installed and positioned according to the rules of equidistant distribution longitudinally and horizontally and symmetry about the center point, the upper and lower central axes, and the left and right central axes, so as to reduce the thermal field differences at each point caused by the introduction of the positioning pieces 14 and improve the consistency and stability of the thermal field.
[0027] Second step, the positioning pieces 14 are fixed on the basic bracket. Whether there are sample boxes on the positioning pieces 14 or not, the consistency and stability of the up-and-down circulating thermal field can be maintained. When measuring the moisture content of cigarettes, the sample boxes only need to be placed on the positioning pieces 14 and dried according to the requirements. This bracket can ensure the stability of the circulating hot air from top to bottom and from bottom to top, and the moisture stability at each positioning point is significantly improved.
[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the utility model, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the utility model.
