Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of filter rod burst bead detection device, and in particular to a calibration rod for a burst bead position detection device. Background Technology
[0002] In the cigarette and food industries, capsule flavoring is widely used. The accuracy of the capsule's position directly affects product quality and user experience. To ensure accurate capsule positioning, a capsule position detection device is typically used. However, over long-term use, the detection accuracy of this device may deviate due to environmental factors and mechanical wear. Therefore, regular calibration of the detection device is crucial for ensuring accuracy.
[0003] Currently, Chinese patent CN213748314U discloses a standard rod for calibrating a microwave-based burst bead position detector. This involves setting a burst bead area in the tobacco section and / or filter section, with a calibration element installed on this area. Since the calibration element characterizes the burst bead position, a microwave resonator is used to obtain a waveform curve of the calibration element, which is then used to calibrate the instrument. However, this existing calibration rod only calibrates the burst bead position detection device. After completing the calibration steps, operators cannot verify the validity of the calibration results using this rod or tool. This makes it difficult for operators to determine whether the detection device has truly achieved the expected accuracy requirements after calibration, potentially leading to a situation where "calibration has been performed, but the detection device remains inaccurate." In such cases, directly using an unverified detection device for product testing could result in a large number of substandard products entering the market, severely impacting product quality control and causing significant economic losses and reputational risks for enterprises.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model provides a calibration rod for a popping bead position detection device, including a calibration rod body 1 and a plurality of standard popping beads 2. Exemplarily, the calibration rod body 1 is a composite material of cellulose acetate and carbon fiber. Carbon fiber provides high strength and stability, reducing deformation and wear of the calibration rod during repeated use. Cellulose acetate maintains similarity to the filter rod, ensuring calibration accuracy.
[0031] Specifically, refer to Figure 2 and Figure 3 The calibration rod body 1 is cylindrical and has multiple mounting cavities 11, which are spaced apart along the axial direction of the calibration rod body 1. Multiple standard popping beads 2 are respectively disposed in each mounting cavity 11, and the center of the standard popping beads 2 is located on the axis of the calibration rod body 1.
[0032] This application provides multiple axially spaced mounting cavities 11 on a cylindrical calibration rod body 1, and sets standard popping beads 2 with their centers located on the axis of the calibration rod body 1 within each mounting cavity 11. This not only enables precise calibration of the popping bead position detection device using the calibration rod body 1, but also allows verification of the validity of the calibration results of the calibration rod body 1 using the known accurate positions of the multiple standard popping beads 2. This effectively solves the problem that existing calibration tools cannot verify calibration results, thereby improving the accuracy and reliability of the popping bead position detection device.
[0033] In some embodiments, the calibration rod body 1 has positioning marks (not shown in the figure) at both ends or one end for calibrating the popping bead position detection device. During calibration, the operator can accurately place the calibration rod in the corresponding position of the detection device according to the positioning marks to ensure the accuracy of the calibration.
[0034] Specifically, when calibrating the capsule position detection device using the calibration rod of this invention, the calibration rod is first placed at the detection position of the capsule position detection device, and precise positioning is achieved using the positioning marks on the calibration rod body 1. For example, for a calibration rod with a length of 120mm, the calibration interface is selected on the main interface of the capsule position detection device, and the brand number of the calibration rod to be tested is selected. Then, the length of the calibration rod is measured multiple times using the positioning marks, thereby completing the calibration of the "length measurement system" inside the capsule position detection device. After calibration, the length of the calibration rod and the position of the standard capsule 2 on the calibration rod body 1 are detected using the capsule position detection device. The detection results are compared with the actual results. If the deviation between the detection results and the actual results is within the allowable range, the calibration result is valid, and the capsule position detection device can be used normally. If the deviation exceeds the allowable range, the calibration operation needs to be repeated until the calibration result is valid. For example, for a calibration rod with a length of 120mm, after completing the calibration operation, its length is detected using the capsule position detection device to obtain a detection result. During the aforementioned testing process, the popping bead position detection device calculates the range of position (15±1.5mm, 45±1.5mm, 75±1.5mm, 105±1.5mm) for each standard popping bead 2 based on the measured length (assuming the measured calibration rod length is 120mm). When the popping bead position detection device detects the position of the standard popping bead 2, its imaging system performs image detection on the position of the standard popping bead 2. Then, the control system compares the popping bead position detected by the imaging system with the calculated position of the standard popping bead 2 to verify the validity of the calibration result.
[0035] It should be noted that the length of the calibration rod, the position of the standard bursting bead 2, and the brand of the standard bursting bead 2 can be determined according to actual production requirements. For example, for a slim filter rod, the length standard is 120 ± 0.5 mm, so the calibration rod is made into a sample rod of 120 mm. If the filter rod produced is 100 mm, the calibration rod is made into a sample rod of 100 mm, and the position of the corresponding standard bursting bead 2 changes proportionally according to the length of the calibration rod. Secondly, most of the filter rods produced in actual production have 4 bursting beads, which are respectively within the position ranges of 15 mm, 45 mm, 75 mm, and 105 mm (taking a 120 mm filter rod as an example), and the process requirements of the filter rod stipulate that the position deviation of the bursting bead in the filter rod does not exceed ±1.5 mm of the corresponding position, but it is not limited to the case of only 4 bursting beads. In addition, the brands of the bursting beads produced in actual production include but are not limited to essence or slim 30 or cross-over. The brand of the standard bursting bead 2 is set according to the brand of the bursting bead produced in actual production, and the brand of the calibration rod is set according to the brand of the standard bursting bead 2.
[0036] In some embodiments, as Figure 3 shown, the installation cavity 11 extends along the radial direction of the calibration rod body 1. The two ends of the installation cavity 11 are respectively the first end 111 and the second end 112. The standard bursting bead 2 is arranged at the first end 111, and the second end 112 is provided with an opening. Optionally, the first end 111 is provided with a concave spherical surface, and the radius of the concave spherical surface is equal to the radius of the standard bursting bead 2. The surface of the standard bursting bead 2 is in contact with the concave spherical surface. The concave spherical surface and the standard bursting bead 2 are in clearance fit, and the size of the concave spherical surface is opened according to the size of the standard bursting bead 2. The standard bursting bead 2 falls into the concave spherical surface, and the concave spherical surface plays a positioning role for the standard bursting bead 2, ensuring that the center of the standard bursting bead 2 is located on the axis of the calibration rod body 1, thereby achieving precise positioning.
[0037] In some embodiments, referring to Figure 1 and Figure 2 , the calibration rod further includes a limiting member 12. The limiting member 12 is arranged in the installation cavity 11 and is used to limit the position of the standard bursting bead 2 in the installation cavity 11. Through this cooperation form of the installation cavity 11 and the limiting member 12, it is convenient for the installation and disassembly of the standard bursting bead 2, and can also ensure the stable position of the bursting bead in the installation cavity 11, meeting the requirements of calibration and verification.
[0038] By providing an open mounting cavity 11 and a limiting member 12, the operator can easily add or remove the standard popping bead 2 from the calibration rod body 1. This structure greatly facilitates the maintenance and replacement of the standard popping bead 2. If one of the standard popping beads 2 is worn or damaged, it can be replaced individually, reducing usage costs and preventing the entire calibration rod from being scrapped due to a problem with a single standard popping bead 2. Furthermore, the detachable nature of the standard popping bead 2 plays a crucial role in the post-calibration testing and verification process. After completing the calibration operation, the operator can remove one of the standard popping beads 2 and then test the calibration rod. This operation verifies whether the popping bead position detection device can correctly identify missing beads, thus effectively verifying whether the device's function in identifying missing standard popping beads 2 is normal. If the device can accurately identify missing beads, it indicates that its missing bead detection function is normal after calibration; otherwise, it suggests a possible malfunction or the need for further adjustment and calibration.
[0039] Regarding the setting method of the limiting member 12, this utility model provides two implementation methods.
[0040] Implementation method one: such as Figure 2 As shown, the limiting member 12 is a limiting post 121, which is at least partially inserted into the mounting cavity 11. Exemplarily, the limiting post 121 is a screw, and the side wall of the mounting cavity 11 is provided with internal threads. The screw is inserted into the mounting cavity 11 and threadedly connected to the mounting cavity 11.
[0041] Furthermore, the bottom end of the limiting post 121 can directly contact the standard burst bead 2 (e.g., Figure 2 As shown in the figure, an elastic element (not shown) can also be provided between the end of the limiting post 121 and the standard popping bead 2, so that the elastic element contacts the standard popping bead 2. For example, the elastic element is a soft pad made of rubber material. When the operator gently twists the limiting post 121 with the soft pad into the mounting cavity 11 and makes the soft pad contact the standard popping bead 2, the soft pad is in a slightly compressed state. This can not only avoid damage to the standard popping bead 2 from hard contact between the limiting post 121 and the standard popping bead 2, but also make the standard popping bead 2 fit more tightly against the concave spherical surface, further ensuring its positional accuracy.
[0042] Implementation Method 2: The limiting component 12 is an elastic retaining ring (not shown in the figure), the inner diameter of which is smaller than the outer diameter of the standard bursting bead 2. When the standard bursting bead 2 is inserted into the opening, the elastic retaining ring will stop the standard bursting bead 2, achieving a firm fixation and ensuring that the standard bursting bead 2 will not shift during the testing process. For example, the elastic retaining ring is designed with a double-layer structure. The inner layer of the elastic retaining ring is made of silicone, which directly contacts the standard bursting bead 2 to avoid damage to it; the outer layer is made of rubber to provide sufficient elasticity. Furthermore, tiny protrusions can be provided on the surface of the inner silicone layer to increase the friction with the standard bursting bead 2, further ensuring that the standard bursting bead 2 is firmly fixed.
[0043] It should be noted that the inner diameter of the elastic retaining ring can be customized according to different specifications of standard burst beads 2 to ensure compatibility.
[0044] It should be noted that in the examples and description of this utility model, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
[0045] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
