Description

Technical Field

[0001] The utility model relates to the field of cigarette making equipment, and more specifically, to a positioning device for detecting the moisture content of a filter rod. Background Art

[0002] The moisture content of filter rods is an important indicator of filter rod quality. The moisture content will affect the moisture content and mainstream smoke of cigarettes, and thus affect the intrinsic quality of cigarettes. At the same time, it is also easy to cause mildew during the storage of filter rods or cigarettes, shortening the storage period. Therefore, the detection of filter rod moisture content is of great significance to the quality and safety of cigarettes and filter rod products.

[0003] At present, the tobacco industry tests the moisture content of filter rods in accordance with GB / T 22838.8 Determination of physical properties of cigarettes and filter rods Part 8: Moisture content. The standard stipulates: "Sample box: diameter of about 64mm, height of about 40mm, good sealing required; sample box placed in the middle layer of the oven for forced air drying, sample box placement density not less than 1 / 120cm2", while the current inspectors place the sample boxes in the oven by visually estimating the spacing between the sample boxes. The visual estimation method is difficult to ensure that the spacing between the sample boxes is consistent, and often does not meet the standard requirements. In addition, the uneven placement of the sample boxes will cause poor circulation of hot air flow inside the oven, resulting in different heating surfaces of the sample boxes, thus affecting the accuracy of the experimental data.

[0004] As filter rod manufacturers expand their production capacity and increase filter rod specifications, a large number of sample moisture content tests are required on a daily basis. However, the standard requires that only the middle layer of the oven be used for forced air drying. Using the oven's built-in partitions to place sample boxes only provides two-dimensional space, and the effective utilization rate of the middle layer of the oven is low. In daily work, repeated tests are required to complete the day's work, resulting in low work efficiency.

[0005] The existing filter rod moisture content detection and positioning devices still have some defects and shortcomings in design, such as: an oven positioning support plate for measuring the moisture content of cigarettes and filter rods with authorization announcement number CN 208721527 U. Although this solution can ensure the spacing of sample boxes, it is only applicable to a specific type of oven due to the fixed size of the support plate, and it is difficult to promote and apply it widely. At the same time, this solution only focuses on two-dimensional space, and the sample boxes are placed on the left and right. The middle space of the oven cannot be effectively utilized, and it is difficult to improve work efficiency.

[0006] Therefore, how to provide a filter rod moisture content detection and positioning device with a simple structure and easy use has become a technical problem that urgently needs to be solved in the field. Utility Model Content

[0027] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0028] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0029] according to Figure 1 As shown, the utility model provides a positioning device for detecting the moisture content of a filter rod, comprising a fixed frame, two ends of which are provided with connecting frames 3, and a detection sample box is placed between the connecting frames 3.

[0030] A longitudinal concave plug hole 4 is provided at the top of the connection frame 3, and a longitudinal convex plug pin 5 is provided at the bottom. The longitudinal concave plug hole 4 and the longitudinal convex plug pin 5 cooperate with each other so that the fixed frames can be stacked longitudinally.

[0031] A transverse concave plug hole 6 is provided on the rear side of the connecting frame 3, and a transverse convex plug pin 7 is provided on the front side. The transverse concave plug hole 6 and the transverse convex plug pin 7 cooperate with each other so that the fixed frame can be spliced ​​transversely.

[0032] During implementation, longitudinal convex pins 5 are arranged at the bottom of the connecting frames 3 on both sides, totaling four, and longitudinal concave holes 4 are arranged at the upper part, totaling four, for connecting multiple filter rod moisture detection and positioning devices up and down. Two groups of transverse concave holes 6 and transverse convex pins 7 are arranged in parallel on the front and rear sides of the connecting frame 3, for connecting multiple filter rod moisture detection and positioning devices left and right. Multiple filter rod moisture detection and positioning devices are connected through the above up and down connection and left and right connection methods, thereby realizing the expansion of three-dimensional space. In daily work, inspectors can select a suitable number of filter rod moisture content detection and positioning devices according to the number of samples to be tested or different types of ovens, and combine them together through up and down and left and right connection methods. This scheme can simultaneously measure a large number of samples to be tested, while ensuring the sample spacing requirements, it also meets the requirements of the national standard "middle layer blast drying in the oven", makes full use of the middle space of the oven, thereby significantly improving work efficiency, and also ensures smooth circulation of hot air flow inside the oven, uniform heating of the sample box, and ensures the accuracy of experimental data.

[0033] When the number of samples is small, only the transverse concave sockets 6 and the transverse convex pins 7 on the connecting frame 3 are used for connection, and multiple filter rod moisture content detection and positioning devices are connected left and right. After the connection is completed, the connecting frame is held to place the multiple filter rod moisture content detection and positioning devices into the middle partition of the oven to carry out the experiment; when the number of samples is large, the two-dimensional space can no longer meet the requirements of one experiment, and the longitudinal concave sockets 4 and the longitudinal convex pins 5 on the connecting frame 3 are used for connection, and multiple filter rod moisture content detection and positioning devices are connected and fixed up and down, and two or three layers of filter rod moisture content detection and positioning devices with moisture content sample boxes are placed into the middle partition of the oven to carry out the experiment.

[0034] Furthermore, the fixed frame includes an upper positioning frame 1 and a lower supporting frame 2 . The positioning frame 1 and the supporting frame 2 are parallel to each other and are fixedly connected to the connecting frame 3 , respectively.

[0035] During implementation, the fixed frame is an integrated frame structure, and the bottom is composed of four parallel and equidistant aluminum alloy tubes to carry the sample box. The middle part of the positioning device is enclosed by aluminum alloy tubes to form a square with a side length of 84mm, totaling four. The four squares are arranged in parallel and 26mm apart from each other. The sample box is placed in the middle square and supported by the bottom of the positioning device. This design meets the national standard requirement: "The sample box placement density is not less than 1 / 120cm2", which avoids inspectors from placing sample boxes by visual estimation and ensures that the placement spacing of each sample box is consistent.

[0036] Furthermore, a plurality of positioning rods 9 are provided in the positioning frame 1 , and a positioning frame is formed between two adjacent positioning rods 9 and the positioning frame 1 . The detection sample box is placed in the positioning frame, and the positioning rods 9 are arranged along the width direction of the positioning frame 1 .

[0037] When it is necessary to carry out the moisture content determination of the filter rod, the oven partition is placed flat in the middle of the oven. According to the number of samples to be tested and the specifications and dimensions of the internal space of the oven, an appropriate number of detection positioning devices are selected, and the detection sample boxes containing the samples to be tested are placed one by one into the positioning boxes in the middle of the fixed frame. There are four positioning boxes in the middle of each fixed frame, which can hold a total of four moisture content sample boxes. The designed positioning boxes have ensured that the sample box placement density complies with national standards and that the sample box placement position meets standard requirements and is under the same uniform experimental conditions, thus avoiding air turbulence in the oven.

[0038] Furthermore, according to the actual situation, that is, the top size of the detection sample box, in order to place two adjacent groups of detection sample boxes to overlap or touch each other, the positioning rods 9 between two adjacent groups of positioning frames can be fitted together or have a gap.

[0039] Furthermore, a plurality of support rods 10 are arranged in the support frame 2, and the distance between two adjacent support rods 10 is smaller than the shortest dimension of the bottom of the test sample box, and the support rods 10 are arranged along the length direction of the support frame 2. Through the gaps between the support rods 10, the oven airflow can flow upward from the gaps, ensuring smooth circulation of hot air flow inside the oven, uniform heating of the sample box, and accurate experimental data.

[0040] Furthermore, a plurality of stabilizing columns 11 are provided between the positioning frame 1 and the supporting frame 2. The plurality of stabilizing columns 11 strengthen the connection strength between the positioning frame 1 and the supporting frame 2, thereby ensuring the overall stability of the fixing frame.

[0041] Furthermore, two groups of connecting tubes 8 are provided at opposite ends of the connecting frame 3, and the axes of the two groups of connecting tubes 8 at the same end are collinear; the transverse concave socket 6 is arranged at the outer end of one group of connecting tubes 8, and the transverse convex pin 7 is arranged at the outer tube of the other group of connecting tubes 8, so that when the fixed frames are horizontally spliced, the transverse convex pin 7 can be inserted into the transverse concave socket 6 of the other group of fixed frames.

[0042] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
