Description

Technical Field

[0001] This application relates to the field of cigarette processing technology, and in particular to a filter rod fragrance line detection device. Background Technology

[0002] Cigarette filter cords contain specially formulated flavorings, which adhere to the filter cord after it is immersed in a flavoring liquid. Currently, to ensure that the amount of flavoring adhering to the filter cord meets the requirements, it is often necessary to test the flavoring content of the filter cord.

[0003] In related technologies, the fragrance content can be determined by detecting the resistance value of the fragrance wire between two copper tubes. However, when using related detection devices, the fragrance wire of the filter rod needs to be clamped and fixed first. However, the position of the clamping mechanism is relatively fixed. When encountering fragrance wires of different lengths, it is often necessary to go through the steps of disassembly, movement and re-locking. It is impossible to quickly adjust according to the length of the fragrance wire, which significantly reduces the detection efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a filter rod fragrance thread detection device to solve the problem that the existing filter rod fragrance thread detection devices are cumbersome to operate, resulting in low detection efficiency.

[0005] This application provides a filter rod fragrance thread detection device, which includes a base, a driving component, a bidirectional threaded rod, and clamping components. The driving component is mounted on the base. The bidirectional threaded rod includes a first threaded segment and a second threaded segment, with the threads on the first and second threaded segments having opposite directions. There are two clamping components, which are threadedly connected to the first and second threaded segments respectively, for cooperating in clamping the filter rod fragrance thread. The driving component is drivenly connected to the bidirectional threaded rod to drive the bidirectional threaded rod to rotate, thereby causing the two clamping components to move towards or away from each other.

[0006] In one embodiment, a first bevel gear is fixedly connected to the output end of the drive unit, and a second bevel gear is fixedly connected to the bidirectional threaded rod, wherein the first bevel gear and the second bevel gear are meshed together.

[0007] In one embodiment, the second bevel gear is fixedly connected between the first threaded segment and the second threaded segment.

[0008] In one embodiment, one of the base and the clamping assembly is provided with a slide rail portion and the other is provided with a slider portion, the slider portion extending into the slide rail portion and being able to slide along the slide rail portion; wherein, the slide rail portion extends axially along the bidirectional threaded rod.

[0009] In one embodiment, the clamping assembly includes a clamping seat, a movable plate, and a pusher. The clamping seat is connected to the bidirectional threaded rod and has a first clamping groove. The pusher is mounted on the clamping seat and its output end is connected to the movable plate, which drives the movable plate to move toward or away from the first clamping groove. The movable plate has a second clamping groove, which is used to cooperate with the first clamping groove to clamp the filter rod fragrance thread.

[0010] In one embodiment, the base has a receiving cavity and a guide channel communicating with the receiving cavity. The guide channel extends axially along the bidirectional threaded rod. The driving member and the bidirectional threaded rod are both installed in the receiving cavity. One end of the clamping assembly away from the bidirectional threaded rod extends out of the receiving cavity through the guide channel, and the clamping assembly slides and guides the side wall of the guide channel.

[0011] In one embodiment, the filter rod fragrance line detection device further includes a tray disposed between the two clamping components and connected to the base.

[0012] In one embodiment, one of the base and the tray has a protruding positioning block and the other has a recessed positioning groove, the positioning block extending into the positioning groove to position the base and the tray.

[0013] In one embodiment, one of the outer sidewall of the positioning block and the inner sidewall of the positioning groove is recessed to form an installation groove, and the other is recessed to form a locking groove, with the installation groove and the locking groove being correspondingly provided; the filter rod fragrance line detection device further includes an elastic element and a locking element, the elastic element and the locking element being installed in the installation groove, and the two ends of the elastic element respectively abutting against the inner wall of the installation groove and the locking element, so that the locking element at least partially protrudes from the installation groove and engages with the locking groove.

[0014] In one embodiment, the end of the snap-fit ​​member away from the elastic member and / or the inner wall of the snap-fit ​​groove are provided with an arc surface.

[0015] Compared with existing technologies, the filter rod fragrance thread detection device provided in this application, by setting up a driving component and a bidirectional threaded rod, allows the two clamping components to move towards or away from each other simply by driving the bidirectional threaded rod to rotate when the position of the clamping components needs to be adjusted. This enables the distance between the two clamping components to be quickly adjusted to accommodate filter rod fragrance threads of different lengths, facilitating the detection of filter rod fragrance threads of varying lengths. Thus, the entire adjustment method is simple and easy to operate, effectively improving the detection efficiency of the filter rod fragrance thread detection device. Attached Figure Description

[0029] Cigarette filter cords contain specially formulated flavorings, which adhere to the filter cord after it is immersed in a flavoring liquid. Currently, to ensure that the amount of flavoring adhering to the filter cord meets the requirements, it is often necessary to test the flavoring content of the filter cord.

[0030] In related technologies, the fragrance content can be determined by detecting the resistance value of the fragrance wire between two copper tubes. However, when using related detection devices, the fragrance wire of the filter rod needs to be clamped and fixed first. However, the position of the clamping mechanism is relatively fixed. When encountering fragrance wires of different lengths, it is often necessary to go through the steps of disassembly, movement and re-locking. It is impossible to quickly adjust according to the length of the fragrance wire, which significantly reduces the detection efficiency.

[0031] Please see Figures 1-5 To address the problem of cumbersome operation and low detection efficiency in existing filter rod fragrance thread testing devices, this application provides a filter rod fragrance thread testing device 100. The device 100 includes a base 10, a drive component 20, a bidirectional threaded rod 30, and clamping components 40. The drive component 20 is mounted on the base 10. The bidirectional threaded rod 30 includes a first threaded section 31 and a second threaded section 32, with opposite thread directions. Two clamping components 40 are provided, each threadedly connected to the first threaded section 31 and the second threaded section 32, respectively, and are used to clamp the filter rod fragrance thread. The drive component 20 is driven by the bidirectional threaded rod 30, driving it to rotate and causing the two clamping components 40 to move towards or away from each other.

[0032] Understandably, by configuring the driving component 20 and the bidirectional threaded rod 30, when the position of the clamping assembly 40 needs to be adjusted, the driving component 20 only needs to drive the bidirectional threaded rod 30 to rotate, and the two clamping assemblies 40 can move towards or away from each other, thereby quickly adjusting the distance between the two clamping assemblies 40 to accommodate filter rod fragrance lines of different lengths, facilitating the detection of filter rod fragrance lines of different lengths. Thus, the entire adjustment method is simple and easy to operate, effectively improving the detection efficiency of the filter rod fragrance line detection device 100.

[0033] Specifically, in one embodiment, such as Figure 2 and Figure 3 As shown, a first bevel gear 21 is fixedly connected to the output end of the drive component 20, and a second bevel gear 33 is fixedly connected to the bidirectional threaded rod 30. The first bevel gear 21 and the second bevel gear 33 are meshed together. Through the cooperation of the first bevel gear 21 and the second bevel gear 33, the drive component 20 can drive the bidirectional threaded rod 30 to rotate, reducing the driving difficulty. At the same time, the rotational speed of the bidirectional threaded rod 30 can be adjusted according to the gear ratio of the first bevel gear 21 and the second bevel gear 33, thereby controlling the moving speed of the two clamping components 40.

[0034] To ensure uniform force distribution on the bidirectional threaded rod 30, in one embodiment, a second bevel gear 33 is fixedly connected between the first threaded section 31 and the second threaded section 32. Simultaneously, the second bevel gear 33 enables equal division of the bidirectional threaded rod 30, and the distance between the two clamping assemblies 40 and the second bevel gear 33 is preferably kept constant.

[0035] In one embodiment, such as Figure 2As shown, one of the base 10 and the clamping assembly 40 is provided with a slide rail portion 103, and the other is provided with a slider portion 41. The slider portion 41 extends into the slide rail portion 103 and can slide along the slide rail portion 103. The slide rail portion 103 extends axially along the bidirectional threaded rod 30. In this way, the cooperation between the slide rail portion 103 and the slider portion 41 can further improve the stability of the movement of the clamping assembly 40 and prevent the clamping assembly 40 from deviating.

[0036] Specifically, in this embodiment, the slide rail 103 is disposed on the base 10, and the slider 41 is disposed on the clamping assembly 40.

[0037] In one embodiment, such as Figure 4 As shown, the clamping assembly 40 includes a clamping base 42, a movable plate 43, and a pushing member 44. The clamping base 42 is connected to the bidirectional threaded rod 30, and a first clamping groove 401 is provided on the clamping base 42. The pushing member 44 is mounted on the clamping base 42, and its output end is connected to the movable plate 43, which is used to drive the movable plate 43 to move towards or away from the first clamping groove 401. The movable plate 43 is provided with a second clamping groove 402, which is used to cooperate with the first clamping groove 401 to clamp the filter rod fragrance line. The slider part 41 can be connected to the clamping base 42. It is easy to understand that when the pushing member 44 pushes the movable plate 43 towards the first clamping groove 401, the first clamping groove 401 can cooperate with the second clamping groove 402 to clamp the filter rod fragrance line, thus facilitating inspection. When the pushing member 44 pushes the movable plate 43 away from the first clamping groove 401, it is easier to place or remove the filter rod fragrance line, making operation simpler.

[0038] Specifically, a first semicircular tube 421 is connected to the clamping base 42, and a second semicircular tube 431 is connected to the moving plate 43. The first semicircular tube 421 forms a first clamping groove 401, and the second semicircular tube 431 forms a second clamping groove 402. Both the first semicircular tube 421 and the second semicircular tube 431 are made of metal to facilitate resistance measurement when used with the filter rod and incense wire. For example, the first semicircular tube 421 and the second semicircular tube 431 can be made of copper or copper alloy tubes, etc.

[0039] Furthermore, in one embodiment, the base 10 has a receiving cavity 101 and a guide channel 102 communicating with the receiving cavity 101. The guide channel 102 extends axially along the bidirectional threaded rod 30. The driving member 20 and the bidirectional threaded rod 30 are both installed in the receiving cavity 101. The end of the clamping assembly 40 away from the bidirectional threaded rod 30 extends out of the receiving cavity 101 through the guide channel 102, and the clamping assembly 40 slides and guides the sidewall of the guide channel 102. This arrangement can, on the one hand, reduce the influence of the external environment on the driving member 20 and the bidirectional threaded rod 30, improve the reliability of the structure, and improve space utilization; on the other hand, it can further improve the stability and reliability of the movement of the clamping assembly 40.

[0040] Since the drive unit 20 and other components in the housing cavity 101 generate heat during operation, in order to reduce the adverse effects of heat accumulation on the operation of the components, in one embodiment, a heat dissipation groove 105 is provided on the base 10, and a heat dissipation mesh 12 is installed at the heat dissipation groove 105. This not only dissipates the heat in the housing cavity 101 to the outside, but also prevents external impurities from entering the housing cavity 101 through the heat dissipation groove 105, thereby ensuring the safety of the filter rod fragrance line detection device 100.

[0041] In one embodiment, such as Figure 1 As shown, a support leg 13 is installed on the base 10, and an anti-slip pad 131 is installed on the bottom of the support leg 13 to increase the friction between the base 10 and the ground, etc., so that the base 10 is more stable when in use.

[0042] Specifically, there are four support legs 13, which are located at the four corners of the base 10. Each support leg 13 has an anti-slip pad 131 at its bottom.

[0043] In one embodiment, such as Figure 1 and Figure 2 As shown, the filter rod fragrance thread detection device 100 also includes a tray 50, which is disposed between the two clamping components 40 and connected to the base 10. During detection, if the fragrance thread breaks due to operational error, the tray 50 can catch most of the broken fragrance thread, thereby reducing the trouble of subsequent cleaning.

[0044] To facilitate the installation of tray 50, in one embodiment, such as Figure 5As shown, one of the base 10 and the tray 50 has a protruding positioning block 11, while the other has a recessed positioning groove 501. The positioning block 11 extends into the positioning groove 501 to position the base 10 and the tray 50. The cooperation between the positioning block 11 and the positioning groove 501 enables rapid positioning of the base 10 and the tray 50, thereby ensuring the reliable installation position of the tray 50. In other words, the tray 50 of this application is a detachable design, and can be replaced with a tray 50 of appropriate length according to the length of the incense cord, reducing the probability of interference between the tray 50 and the clamping assembly 40.

[0045] Specifically, in this embodiment, the positioning block 11 is disposed on the base 10, and the positioning groove 501 is disposed on the bottom of the tray 50.

[0046] Furthermore, in one embodiment, one of the outer sidewall of the positioning block 11 and the inner sidewall of the positioning groove 501 is recessed to form an installation groove 104, and the other is recessed to form a locking groove 502, with the installation groove 104 and the locking groove 502 correspondingly provided. The filter rod fragrance line detection device 100 also includes an elastic member 60 and a locking member 70, which are installed in the installation groove 104, and the two ends of the elastic member 60 respectively abut against the inner wall of the installation groove 104 and the locking member 70, so that the locking member 70 at least partially protrudes from the installation groove 104 and engages with the locking groove 502. In this way, the firmness of the tray 50 after installation can be further improved, and the connection between the positioning block 11 and the positioning groove 501 can be prevented from failing due to vibration, thereby causing the position of the tray 50 to shift.

[0047] Specifically, in this embodiment, the mounting groove 104 is disposed on the outer side wall of the positioning block 11, and the slot 502 is disposed on the inner side wall of the positioning groove 501.

[0048] In one embodiment, the end of the snap-fit ​​member 70 away from the elastic member 60 and / or the inner wall of the slot 502 are provided with an arc surface. The arc surface can play a certain guiding role, making the installation and removal of the tray 50 smoother. For example, when installing the tray 50, it only needs to be aligned and pressed down. Guided by the arc surface, the snap-fit ​​member 70 can more easily squeeze the elastic member 60 and retract into the mounting slot 104 until the snap-fit ​​member 70 moves to the position corresponding to the slot 502. At this time, the elastic member 60 returns, and the snap-fit ​​member 70 can be smoothly aligned and inserted into the slot 502, thus realizing the installation of the tray 50. When removing it, it is only necessary to pull the tray 50 with force. Similarly, guided by the arc surface, the snap-fit ​​member 70 can more easily squeeze the elastic member 60 and retract into the mounting slot 104 until the positioning post is completely disengaged from the positioning slot 501, thus realizing the removal of the tray 50.

[0049] To facilitate the handling of the tray 50, a handle 51 can be provided on the tray 50. The handle 51 can be provided with anti-slip stripes to increase the friction between the handle 51 and the hand, reduce slippage, and improve overall safety.

[0050] In use, the filter rod incense thread detection device 100 provided in this application can first activate the drive component 20, which drives the first bevel gear 21 to rotate. The first bevel gear 21, through meshing with the second bevel gear 33, drives the second bevel gear 33 and the bidirectional threaded rod 30 to rotate, thereby driving the two clamping components 40 to move synchronously, realizing the rapid adjustment of the distance between the two clamping components 40 to adapt to incense threads of different lengths. After adjusting the position of the clamping components 40, the incense thread can be placed on the first semi-circular tube 421 connected to the clamping base 42. Then, the push component 44 is activated, which drives the moving plate 43 to move, and clamps and fixes the incense thread through the second semi-circular tube 431 connected to the moving plate 43, ensuring reliable installation of the incense thread. Finally, the fragrance content of the incense thread can be detected.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
