[0043] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0044] like Figure 1-3 As shown, a filter rod spiral line production device comprises:

[0045] Rack 1;

[0046] A rotary drive mechanism 2, wherein the rotary drive mechanism 2 is mounted on the frame 1;

[0047] A rotating assembly 3, the rotating assembly 3 is rotatably mounted on the frame 1, and the rotating assembly 3 is provided with an annular cavity;

[0048] The central guide tube 4 is a hollow structure, and is disposed at the axial center of the annular cavity of the rotating assembly 3. The side wall of the central guide tube 4 is provided with at least one radial through hole, and the central guide tube 4 is suitable for guiding the filter rod to pass through;

[0049] A heating assembly 5, which is movably mounted in the annular cavity of the rotating assembly 3, and is provided with a heating tip, which is suitable for passing through the radial through hole to contact and heat the filter rod passing through the central guide tube 4;

[0050] The rotary drive mechanism 2 is suitable for driving the rotary assembly 3 and the central guide tube 4 to rotate synchronously.

[0051] In this embodiment, if Figure 1-3As shown, the heating component 5 is first preheated to prepare for the next operation. Subsequently, the rotary drive mechanism 2 is started, driving the rotary component 3 and the central guide tube 4 and the heating component 5 disposed in the rotary component 3 to rotate synchronously. At this time, the filter rod passes through the hollow structure of the central guide tube 4, and the heating tip of the heating component 5 contacts the filter rod through the radial through hole of the central guide tube 4. In this process, the heating tip forms a spiral line on the surface of the filter rod, realizing innovation in the design shape of the filter rod. The spiral pitch can be adjusted according to the filter rod conveying speed and the speed of the rotary drive mechanism 2.

[0052] The filter rod can specifically be a tobacco acetate composite filter rod.

[0053] Specifically, Figure 1-3 As shown, the filter rod spiral line production device also includes a heating component displacement mechanism, and the heating component displacement mechanism can be the following structure, including:

[0054] A fixed slide rail, which is installed on the inner wall of the annular cavity of the rotating component 3;

[0055] A main slide block 6, the main slide block 6 is slidably mounted on the fixed slide rail, and the main slide block 6 is suitable for being fixed on the fixed slide rail through a fixing member;

[0056] The heating assembly 5 is mounted on a main slider 6 , and the main slider 6 is adapted to be adjusted to change the distance between the heating tip of the heating assembly 5 and the axis of the central guide tube 4 .

[0057] In this embodiment, if Figure 1-3 As shown, the heating component displacement mechanism allows the position of the heating component 5 to be precisely adjusted to ensure that the contact position between the heating tip and the filter rod is accurate. The distance between the heating component 5 and the central guide tube 4 can be adjusted according to filter rods of different specifications or different spiral line depth requirements.

[0058] When in use, first, according to the filter rod specifications and the required spiral line parameters, the operator sets the initial position of the main slide 6 on the fixed slide rail by adjusting the fixings. Then, if the heating position needs to be fine-tuned, the fixings can be slightly loosened, the main slide 6 can be moved slightly, and finally fixed. When in use, when the rotating component 3 rotates, the heating component 5 rotates accordingly, but their relative positions remain unchanged, ensuring a continuous and stable heating effect.

[0059] Specifically, Figure 1-3 As shown, the heating component displacement mechanism also includes:

[0060] A secondary slider 7, the secondary slider 7 is slidably mounted on the main slider 6, a metal mounting plate 71 is provided on the secondary slider 7, and the heating assembly 5 is mounted on the metal mounting plate 71;

[0061] A reset elastic member, which is arranged on the auxiliary slider 7;

[0062] The main slide block 6 is provided with a resetting elastic member installation groove, and one end of the resetting elastic member is suitable for abutting against the resetting elastic member installation groove;

[0063] The resetting elastic member is suitable for driving the auxiliary slider 7 and the heating tip of the heating assembly 5 to separate from the radial through hole of the central guide tube 4;

[0064] The electromagnet 8 is fixedly installed in the annular cavity of the rotating assembly 3 and is located on the opposite side of the fixed slide rail;

[0065] The electromagnet 8 is suitable for adsorbing the metal mounting plate 71, driving the auxiliary slider 7 and the heating component 5 on the auxiliary slider 7 to contact the filter rod.

[0066] In this embodiment, if Figure 1-3 As shown, the function of the heating component displacement mechanism is to achieve rapid contact and separation between the heating component 5 and the filter rod through the cooperation of the auxiliary slider 7 and the electromagnet 8. The reset elastic member ensures that the heating component 5 automatically moves away from the filter rod in the non-working state. During use, the reset elastic member, the auxiliary slider 7 and the heating component 5 are in an initial state and are away from the central guide tube 4. When heating starts, the electromagnet 8 is energized to generate magnetic force. The magnetic force attracts the metal mounting plate 71 to overcome the force of the reset elastic member. The auxiliary slider 7 drives the heating component 5 to move, so that the heating tip passes through the radial through hole and contacts the filter rod. When heating is completed, the electromagnet 8 is powered off and the magnetic force disappears. The elastic force of the reset elastic member drives the auxiliary slider 7 and the heating component 5 back to the initial position.

[0067] For the convenience of operation, the heating component 5 interferes with the initial startup and is not in contact with the filter rod. After the startup is normal, the metal mounting plate 71 is attracted by the suction force of the electromagnet 8 so that the heating component 5 is in contact with the filter rod.

[0068] Specifically, Figure 1-3 As shown, the rotation drive mechanism 2 may have the following structure, including:

[0069] A driving source 21, the driving source 21 is mounted on the frame 1, the driving source 21 is provided with an output shaft, and the output shaft is provided with a driving wheel;

[0070] A synchronous pulley, which is fixedly mounted on the rotating assembly 3 and coaxially connected to the rotating assembly 3;

[0071] The transmission belt 22 is wound around the driving wheel and the synchronous pulley.

[0072] In this embodiment, if Figure 1-3As shown, the function of the rotary drive mechanism 2 is to provide rotary power for the entire filter rod spiral line production device. The operation process of the rotary drive mechanism 2 is as follows: after the driving source 21 is started, the driving wheel is driven to rotate through its output shaft. The rotary motion of the driving wheel is transmitted to the synchronous pulley through the transmission belt 22. Since the synchronous pulley is coaxially connected to the rotating component 3, it can drive the rotating component 3 to rotate.

[0073] Specifically, Figure 2 As shown, the driving source 21 is a servo motor.

[0074] Specifically, Figure 2 As shown, the filter rod spiral production device also includes a slip ring assembly 9, and the slip ring assembly 9 includes:

[0075] A fixed conductive ring, wherein the fixed conductive ring is installed on the frame;

[0076] A rotating conductive ring, which is mounted on the rotating assembly and rotates synchronously with the rotating assembly;

[0077] A plurality of groups of brushes are provided on the fixed conductive ring, and the brushes are suitable for electrically connecting the fixed conductive ring with the rotating conductive ring.

[0078] In this embodiment, if Figure 2-3 As shown, the slip ring assembly 9 allows current to be transmitted from the fixed part to the rotating part, providing a continuous and stable power supply for the heating component 5 and other rotating parts that need power. When in use, the fixed conductive ring remains stationary, fixedly connected to the frame, and connected to an external power supply. The rotating conductive ring rotates with the rotating component 3. Multiple sets of brushes maintain continuous contact with the rotating conductive ring to achieve current transmission during the rotation process. The rotating parts obtain the required power through the rotating conductive ring to ensure the normal operation of the equipment.

[0079] The number of fixed conductive rings and rotating conductive rings is not limited to one pair and can be set according to specific needs.

[0080] Specifically, Figure 2-3 As shown, the heating component 5 may have the following structure, including:

[0081] A heat-conducting core, which is disposed in the annular cavity of the rotating assembly 3 and has a heating tip;

[0082] The resistance heating coil is spirally wound on a heat-conducting core.

[0083] Specifically, Figure 2-3 As shown, the heating assembly 5 also includes an insulating shell, which covers the resistance heating coil and the heat conductive core.

[0084] In this embodiment, if Figure 2-3As shown, the resistance heating coil generates heat after being energized. The heat is efficiently transferred to the heating tip through the heat conductive core. The heating tip of the heat conductive core can accurately contact the filter rod to achieve local heating. The insulating shell ensures electrical safety and prevents short circuits and electric shocks. The heating temperature can be controlled by adjusting the current. The heating component 5 can also use existing solutions, such as an electric soldering iron.

[0085] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
