Description

Technical Field

[0001] The utility model relates to the technical field of quality control rod bundling, in particular to a quality control rod bundling device. Background Art

[0002] Applying an appropriate amount of triacetin to the tow of acetate filter rods can increase the rod's hardness, enhance smoke resistance, improve filtration efficiency, and enhance the sensory quality of cigarettes. Currently, filter rod workshops use near-infrared (NIR) testing to determine the amount of triacetin applied to filter rods, control the stability of filter rod processing, and improve cigarette quality. NIR testing is simple, fast, and environmentally friendly. The overtone vibrations and rotations of hydrogen bonds in triacetin produce absorption in the NIR region.

[0003] Near-infrared spectroscopy is an indirect analytical method that requires the use of a mathematical model for quantitative analysis. To ensure the accuracy of the model's predictions, when using near-infrared spectroscopy to measure the amount of triacetin applied to filter rods in the filter rod production workshop, quality control filter rods (hereinafter referred to as "quality control rods") are used daily before routine testing to confirm the model's reproducibility and stability.

[0004] The properties of quality control rods are relatively stable. However, poor storage environments and repeated loading and unloading can easily introduce complex external factors. For example, when the storage environment of quality control rods is not clean, the surface of the quality control rods will be contaminated, affecting the accuracy of near-infrared detection. In the prior art, when calibrating a near-infrared detector, quality control rods need to be inserted and removed one by one, which will cause the surface of the quality control rods to frequently contact with operating tools, causing surface damage. These external factors will destroy the stability of the properties of the quality control rods, shorten the service life of the quality control rods, and also affect the accuracy of near-infrared detection.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0035] An embodiment of the present utility model provides a quality control rod bundling device for storing quality control rods 4 and using the quality control rods 4 for calibrating a near-infrared detector. Figure 1 and Figure 2 The bundler comprises a cup body 1, an inner cavity 2 is provided inside the cup body 1, an interface 3 is provided at the open end of the cup body 1, the inner cavity 2 is used to accommodate the quality control rod 4, and the interface 3 can be adapted to the sample cup 16 of the near infrared detector. Figure 3 As shown. Specifically, the interface portion 3 is adapted to the sample cup 16, which means that the interface portion 3 can be connected to the sample cup 16, and the inner cavity 2 is connected to the internal space of the sample cup 16, so that the end of the quality control rod 4 can be inserted into the sample cup 16 for detection. For example, the interface portion 3 and the cup mouth of the sample cup 16 can be adapted by threaded connection, plug-in connection or snap-on connection. When the quality control rod 4 is inserted into the inner cavity 2, the axis of the cup body 1 is parallel to the axis of the quality control rod 4 inside it, and the end of the quality control rod 4 extends out of the interface portion 3 (as shown in FIG. Figure 1When the cup body 1 is matched with the sample cup 16, the portion of the quality control rod 4 outside the interface portion 3 can extend into the interior of the sample cup 16, so that the near infrared detector can detect the quality control rod.

[0036] By adopting the above technical solution, the quality control stick 4 is stored in the cup body 1, which can prevent the quality control stick 4 from being contaminated due to unclean storage environment. In addition, when the quality control stick 4 needs to be used to calibrate the near-infrared detector, the operator can hold the cup body 1 filled with quality control sticks 4 and turn the cup body 1 upside down on the sample cup 16 (such as Figure 3 As shown), one end of the quality control rod 4 is inserted into the sample cup 16 for detection. This prevents the operator's hands or other operating tools from directly contacting the quality control rod 4, and can also avoid damage to the surface of the quality control rod 4 caused by taking and placing the quality control rods 4 one by one. Therefore, the present application can prevent external factors from affecting the stability of the properties of the quality control rod 4, and prevent the properties of the quality control rod 4 from being damaged by external factors, causing calibration errors of the near-infrared detector, and affecting the accuracy of the near-infrared detection. In addition, by setting the interface portion 3 of the cup body 1 to be compatible with the sample cup 16 of the near-infrared detector, the stability of the cup body 1 can also be improved, preventing the cup body 1 from shaking and affecting the detection accuracy.

[0037] Furthermore, if Figure 1 As shown, the cup body 1 includes a base plate 5, a cylinder 7 and a head 9. The upper surface of the base plate 5 is provided with a first annular protrusion 8. The lower surface of the cylinder 7 is provided with a first annular groove 6, and the upper surface is provided with a second annular groove 10. The first annular groove 6 is plugged into the first annular protrusion 8, and the two are interference fit. The head 9 is annular, and the upper end of the head 9 is provided with an interface portion 3. The lower surface of the head 9 is provided with a second annular protrusion 11. The second annular groove 10 is plugged into the second annular protrusion 11, and the two are interference fit. Specifically, the cylinder 7 includes a first curved plate 12 and a second curved plate 13, and the first curved plate 12 and the second curved plate 13 are detachably connected. When the quality control rods 4 are loaded into the bundling device, the bundled quality control rods 4 are first placed between the first curved plate 12 and the second curved plate 13, and then the first curved plate 12 and the second curved plate 13 are connected to form the cylinder 7, and then the cylinder 7 is plugged into the base plate 5. The upper surface of the bottom plate 5 is a plane. Pressing the quality control rods 4 downwards can align the two ends of each quality control rod 4 , making it easier for the near-infrared detector to detect the ends of each quality control rod 4 .

[0038] Furthermore, if Figure 2As shown, the first curved plate 12 and the second curved plate 13 both have an arc of 180 degrees. The two sides of the first curved plate 12 and the second curved plate 13 are respectively provided with a plug-in slot 14 and a plug-in block 15 extending in the longitudinal direction. The two plug-in blocks 15 are respectively plugged into the two plug-in slots 14. Specifically, the plug-in blocks 15 and the plug-in slots 14 have an interference fit, preventing the first curved plate 12 and the second curved plate 13 from separating and causing the quality control rods 4 to scatter, thereby ensuring the stability of the quality of the quality control rods 4.

[0039] Furthermore, if Figure 1 As shown, the outer diameter of the interface portion 3 is equal to the inner diameter of the sample cup 16, and the interface portion 3 can be plugged into the mouth of the sample cup 16 to adapt the interface portion 3 to the sample cup 16. Specifically, the interface portion 3 and the mouth of the sample cup 16 are spaced apart to facilitate insertion and removal of the binding device when calibrating the near-infrared detector.

[0040] Furthermore, the diameter of the inner cavity 2 is 51 mm, which is smaller than the diameter of the detection end of the near-infrared detector, so that the near-infrared detector can detect the end faces of all quality control rods 4 inside the inner cavity 2. The inner cavity 2 can accommodate 45-50 quality control rods 4.

[0041] Furthermore, the diameter of the control rod 4 is equal to the diameter of the filter rod to be tested, which is 7.6 mm. The length of the control rod 4 is equal to the length of the filter rod to be tested, which is 100 mm. Along the length of the barrel 7, the length of the inner cavity 2 is 79.5 mm, allowing the barrel 7 to accommodate most of the control rod 4 while leaving the upper end of the control rod 4 exposed.

[0042] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above description is provided to further illustrate the present invention in conjunction with specific embodiments, and that the present invention should not be construed as being limited to these descriptions. Those skilled in the art may make various changes in form and detail, including simple deductions or substitutions, without departing from the spirit and scope of the present invention.
