Abstract
Description
Technical Field
[0001] This utility model relates to the field of filter rod bursting bead detection technology, and in particular to a filter rod conveying device and a filter rod detection device. Background Technology
[0002] With the rapid development of tobacco equipment research and development and the technology of flavor capsule cigarettes both domestically and internationally, tobacco companies have developed a type of flavor capsule cigarette that can improve smokers' smoking comfort. Flavor capsule cigarettes refer to cigarettes with small liquid flavor capsules containing different fragrances embedded in the cigarette filter. Smokers can manually squeeze the capsules to release the flavoring liquids into the filter fibers, enhancing the aroma during inhalation, reducing the harmful effects of the cigarette's pungent odor on the smoker's body, and improving smoking comfort.
[0003] The filling of flavor capsules requires that the capsules in the filter rod meet the spacing and head-to-head distance specifications. However, during filling, capsules may be missing or broken, both of which affect the quality of the flavor capsule cigarette. Existing offline testing instruments for flavor capsule filter rods primarily use a conveyor to transport the filter rods through a microwave sensor for testing. As the filter rod passes through the sensor cavity, capsules of different densities and moisture contents cause varying changes in the microwave sensor's energy parameters. Because the capsules are evenly spaced within the filter rod, the microwave sensor's energy parameters exhibit regular changes. When capsules are missing, broken, or misaligned, the changes in the microwave sensor's energy parameters become irregular. The testing instrument analyzes and processes the signals using software to ultimately determine whether the flavor capsule filter rod is normal or defective. However, when the filter rod diameter is small and the distance between the capsules and the filter rod's end face is short, the existing conveyor can interfere with the microwave sensor's energy parameters, making it difficult to confirm the state of the capsules near the filter rod's end face, thus reducing the accuracy of detecting the capsule state within the filter rod. Utility Model Content
[0004] The purpose of this invention is to solve the problem of low accuracy in detecting the bursting state of filter rods with small diameters and short distances from the filter rod end face in existing filter rod testing instruments. This invention provides a filter rod conveying device and a filter rod testing device, which improves the accuracy of detecting the bursting state of the bursting beads in the filter rod by setting the pusher head section of the push rod to a small diameter and hollow structure, thereby reducing interference with the energy parameters of the microwave sensor.
[0005] To solve the above-mentioned technical problems, the present invention discloses a filter rod conveying device for conveying filter rods through a microwave sensor along the entire length direction, comprising: a pusher rail, a push rod, and a drive mechanism;

[0024] 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.
[0025] like Figure 1 and Figure 2 As shown, an embodiment of this utility model provides a filter rod conveying device for conveying filter rod 1 along its entire length (e.g., ...). Figure 1 The component passing through the microwave sensor 7 (shown in the X direction) includes: a push rail 2, a push rod 3, and a drive mechanism 4.
[0026] The push guide rail 2 is used to support the filter rod 1.
[0027] The push rod 3 is used to push the filter rod 1 on the push guide rail 2 to move along the X direction; wherein, the push rod 3 includes a push head section 31 and a push rod positioning section 32. The push head section 31 is designed as a hollow structure, and the inner diameter of the push head section 31 is smaller than the diameter of the filter rod 1. The push rod positioning section 32 is used to position the push rod 3 at its initial position.
[0028] The applicant fully considered the problems encountered in the testing process of existing popping bead filter rod testing instruments. By setting the pusher section 31 of the pusher rod 3 to a small diameter to accommodate the small diameter filter rod 1, and by setting the pusher section 31 to a hollow structure, the length of which can be designed according to the overall length of the pusher rod 3, the interference of the pusher section 31 on the microwave electromagnetic field energy parameters when the pusher rod 3 pushes the filter rod 1 through the microwave sensor 7 is reduced. Through the design of the pusher section 31 of the pusher rod 3, the problem of difficulty in confirming the state of the popping beads near the end face of the filter rod 1 and the low accuracy of detecting the state of the popping beads in the filter rod 1 caused by the structure of the pusher rod 3 is solved.
[0029] Further, refer to Figure 1 The drive mechanism 4 provides the push rod 3 with the power to push the filter rod to move in the X direction; wherein, the drive mechanism 4 includes a slide rail 41 and a power input component 42 slidably mounted on the slide rail 41. The slide rail 41 is arranged parallel to the push guide rail 2. The moving direction of the power input component 42 is parallel to the moving direction of the push rod 3. The push rod 3 is connected to a connecting plate 5. The first end of the connecting plate 5 is perpendicularly connected to the end of the push rod 3, and the second end of the connecting plate 5 is perpendicularly connected to the power input component 42.
[0030] In this embodiment, the power input component 42 is a drive motor, and one end of the drive motor is fixedly connected to the second end of the connecting plate 5.
[0031] Furthermore, a detection switch 6 is provided below the push rod 3. When the push rod positioning section 32 is directly above the detection switch 6, the detection switch 6 determines that the push rod 3 is in the initial position.
[0032] Specifically, filter rod 1 is output from a filter rod library installed above the push rail 2. Under the action of gravity, filter rod 1 in the filter rod library falls onto the side of the push rail 2 near the push rod 3. The push rail 2 is equipped with a filter rod detection switch (not shown in the figure) to detect whether filter rod 1 has fallen into the push rail 2. When the filter rod detection is activated, the detection switch 6 below the push rod 3 starts to detect whether the push rod positioning section 32 is in the initial position, and the filter rod detection switch detects whether filter rod 1 has fallen into the push rail 2. When the detection switch 6 does not detect that the push rod positioning section 32 is in the initial position, the drive motor will drive the push rod 3 to move to the initial position along the X direction. When the detection switch 6 detects that the push rod positioning section 32 is in the initial position and the filter rod detection switch detects that filter rod 1 has fallen into the push rail 2, the detection switch 6 and the filter rod detection switch will transmit detection signals to the control system. After receiving the two detection signals, the control system will control the drive motor to work. The drive motor will slide along the slide rail 41 along the X direction and drive the push rod 3 connected to it to move. As the push rod 3 moves along the X direction, it comes into contact with the end face of the filter rod 1. Therefore, the push rod 3 can push the filter rod 1 through the microwave sensor 7 until the filter rod 1 is completely away from the microwave sensor 7. At this time, the push head section 31 designed in this invention has a hollow structure and a small diameter, which reduces interference with the energy parameters detected by the microwave sensor 7, and thus facilitates the confirmation of the state of the popping beads near the end face of the filter rod 1. After the push rod 3 completes the pushing of one filter rod 1, the push rod 3 returns to the initial position under the action of the drive motor to start conveying the next filter rod 1.
[0033] In practice, the cross-sectional dimension of the push rod 3 is smaller than the size of the feed port of the microwave sensor 7, so that the push rod 3 can push the filter rod 1 until the filter rod 1 is completely away from the microwave sensor 7, thereby improving the detection accuracy of the filter rod 1 by the microwave sensor 7.
[0034] Furthermore, the end of the push rod 3 is provided with a threaded hole, which is threadedly connected to the first end of the connecting plate 5. The threaded connection method not only ensures the tightness of the connection between the push rod 3 and the connecting plate 5, but also improves the convenience of component assembly and disassembly.
[0035] In some embodiments, the push guide 2 is designed with an arc-shaped groove structure. The arc-shaped groove structure is adapted to the structure of the filter rod 1, so that the filter rod 1 can move steadily and smoothly on the push guide, thereby improving the reliability of the device.
[0036] For example, the push rod 3 is made of nylon. Using nylon for the push rod 3 not only facilitates the pushing of the filter rod 1, but also reduces the impact on the detection of the microwave sensor 7.
[0037] Based on the same concept, this utility model also provides a filter rod detection device, including the filter rod conveying device provided in the above embodiments.
[0038] 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.
[0039] 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.
