[0002] A cigarette rolling machine is a machine that rolls tobacco into cigarettes using cigarette paper. During the cigarette production process, special adhesive for filter rods is often used to bond the rolled cigarettes to the filter rods. The filter rods serve to filter the cigarettes, and various composite structures are added to the filter rods to improve the taste and appearance of the cigarettes. However, quality defects such as missing rods, drift, and misalignment can occur during the production of composite filter rods.

[0003] To address the aforementioned issues, the composite filter rods need to be inspected. Current inspection methods involve placing a light source emitting module within the rod-collecting wheel for illumination analysis. After the light source receiving module receives the illumination and forms a circuit, the data is processed by a computer to determine if the internal structure of the filter rod meets standards. However, heat is generated within the rod-collecting wheel during illumination, and prolonged operation can affect the accuracy of the illumination, thus impacting the accuracy of the composite filter rod inspection.

[0004] Therefore, there is an urgent need for composite filter rod cooling devices and cigarette rolling machines to solve the above problems. Summary of the Invention

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0040] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0043] To inspect the added filter rods, the current method involves placing a light source emitting module inside the rod-picking wheel for illumination analysis. After the light source receiving module receives the illumination and forms a circuit, the data is processed by a computer to determine if the internal structure of the filter rod meets standards. However, heat is generated inside the rod-picking wheel during illumination, and prolonged operation can affect the illumination accuracy of the light source, thus impacting the accuracy of the composite filter rod inspection. To address this, this embodiment provides a composite filter rod cooling device that removes the heat dissipated from the illumination assembly, solving the problem of excessive heat generation during prolonged illumination affecting the accuracy of composite filter rod inspection.

[0044] like Figures 1-5 As shown, in this embodiment, the composite filter rod cooling device includes a rotating shaft 1, a drive source, a rod-picking wheel assembly 2, an air distribution assembly 3, and an illumination assembly 4. The drive source drives the rotating shaft 1 to rotate. The rod-picking wheel assembly 2 is rotatably mounted on the rotating shaft 1 and is used to mount the filter rod 100. The air distribution assembly 3 includes an air distribution seat 31 rotatably mounted on the rotating shaft 1 and an air distribution wheel 32 fixedly mounted on the air distribution seat 31. The air distribution wheel 32 is mounted on the rotating shaft 1, and its outer peripheral wall abuts against the rod-picking wheel assembly 2. The air distribution wheel 32 has an air inlet 321 and an air outlet 322. The illumination assembly 4 is disposed inside the air distribution wheel 32 and is used to irradiate the filter rod 100. The illumination assembly 4 has an air chamber that communicates with the air inlet 321 and the air outlet 322 of the air distribution wheel 32. Specifically, the output end of the drive source is connected to the rotating shaft 1, which drives the rotating shaft 1 to rotate. The outer peripheral wall of the rotating shaft 1 is rotatably connected to the gas distribution seat 31, which is fixedly connected to the gas distribution wheel 32. The gas distribution wheel 32 is equipped with a light-illuminating component 4. The light-illuminating component 4 illuminates the filter rod 100 installed on the rod picking wheel assembly 2 and processes and analyzes the light through a computer to determine whether the composite composition inside the filter rod 100 meets the standards. The air inlet 321 of the gas distribution wheel 32 is connected to an external air source. The external air source enters the air chamber of the light-illuminating component 4 through the air inlet 321 and then exits from the air outlet 322 of the gas distribution wheel 32. This can remove the heat dissipated inside the light-illuminating component 4, effectively playing a heat dissipation role and solving the problem that the light source 42 easily generates a lot of heat during long-term illumination, which affects the detection accuracy of the filter rod 100.

[0045] Furthermore, continue to refer to Figures 1-5 The composite filter rod cooling device also includes a gear 7 fixedly connected to the rotating shaft 1. The rotation of the rotating shaft 1 drives the gear 7 to rotate, which inserts the filter rod 100 into the tooth groove of the gear 7. The filter rod 100 is then transported to the top of the light-emitting component 4 by the rod-picking wheel assembly 2, and then the light-emitting component 4 can be turned on for light analysis and detection.

[0046] Furthermore, continue to refer to Figures 1-5 The air distribution assembly 3 also includes a connector 33, which is connected to the air distribution wheel 32 and is connected to the air inlet 321. The connector 33 is used to connect to an external air source. Specifically, one end of the connector 33 is fixedly connected to the air distribution wheel 32 and connected to the air inlet 321, and the other end of the connector 33 is connected to an external air source. The cold air provided by the external air source is delivered to the air cavity through the connector 33 to dissipate heat and cool the light-emitting assembly 4 and the air distribution wheel 32.

[0047] Furthermore, continue to refer to Figures 1-5 The lighting assembly 4 includes a housing 41, a light source 42, and a heat spreader 43. The housing 41 is fixedly connected to the inside of the gas distribution wheel 32. The heat spreader 43 and the light source 42 are both located in the air cavity. The heat spreader 43 is fixedly connected to the housing 41. The light source 42 is mounted on the heat spreader 43. The heat spreader 43 is used to conduct the heat generated by the light source 42 to the outside of the housing 41. Specifically, the housing 41 is fixedly connected to the outer side of the gas distribution wheel 32. The housing 41 is equipped with a light source 42, which is a lamp bead lens. The housing 41 encapsulates the light source 42. A custom aluminum substrate 47 is fixedly installed on the bottom wall inside the housing 41. The substrate 47 is located below the light source 42. A heat dissipation plate 43 is fixedly connected to the bottom wall inside the housing 41 and is in contact with the substrate 47. The heat dissipation plate 43 is VC liquid-cooled and can be used to remove the heat generated by the substrate 47 during operation, efficiently and evenly conducting the heat generated by the light source 42. At the same time, the heat dissipation plate 43 is in contact with the gas distribution wheel 32. The large inner surface area of ​​the gas distribution wheel 32 increases the heat dissipation area of ​​the light source 42. At the same time, the circulation of cold air can quickly remove the heat of the light source 42, effectively achieving the heat dissipation effect. A cable protection coil 46 is provided on the outer side of the housing 41.

[0048] Furthermore, continue to refer to Figures 1-5 The illumination component 4 also includes a light-transmitting plate 44, which is disposed on the housing 41 and located between the light source 42 and the air outlet 322. The housing 41 has an air outlet channel, the two ends of which are connected to the air chamber and the air outlet 322, respectively. Specifically, two light-transmitting plates 44 are disposed on the outer side of the housing 41. The light-transmitting plates 44 are made of glass. The light emitted by the light source 42 can irradiate the filter rod 100 on the rod-picking wheel assembly 2 through the light-transmitting plates 44. At the same time, the external air source enters the air chamber through the air inlet 321 and then carries away the internal heat through the air outlet 322 via the air outlet channel.

[0049] Furthermore, continue to refer to Figures 1-5 The air outlet channel has an air inlet 411 and an air outlet 412. The air inlet 411 is connected to the air chamber, and the air outlet 412 is connected to the air outlet 322. There are multiple air outlets 412, and the openings of the multiple air outlets 412 are arranged parallel to the light-transmitting plate 44. The air outlets 412 are used to remove dust adsorbed on the light-transmitting plate 44. Specifically, the air outlet channel is located between two light-transmitting plates 44. Cold air enters the air chamber from the air inlet 321 and is then blown out from the air outlets 412 of the air outlet channel, blowing away the dust adsorbed on the light-transmitting plate 44, effectively cleaning the light-transmitting plate 44, and preventing dust accumulation from affecting the light intensity of the light source 42.

[0050] Furthermore, continue to refer to Figures 1-5 The lighting component 4 also includes a first filter cotton 45, which is disposed in the air outlet channel and is used to filter dust in the atmosphere. Specifically, the first filter cotton 45 is fixedly connected inside the air outlet channel to prevent dust from entering the interior of the housing 41 through the air outlet channel, thus achieving a dustproof effect.

[0051] Furthermore, continue to refer to Figures 1-5 The filter rod assembly 2 includes a first filter rod 21 and a second filter rod 22. The first filter rod 21 is rotatably mounted on the rotating shaft 1, and the second filter rod 22 is mounted on the gas distribution wheel 32, and the second filter rod 22 is rotatably connected to the first filter rod 21. Both the first filter rod 21 and the second filter rod 22 are provided with a light-transmitting channel 23, with the two ends of the light-transmitting channel 23 aligned with the light source 42 and the filter rod 100, respectively. Specifically, the first filter rod 21 is provided on the outer side of the gas distribution wheel 32, and the second filter rod 22 is rotatably connected to the outer side of the first filter rod 21. A filter rod 100 cutter is provided on the outer side of the second filter rod 22. Both the first filter rod 21 and the second filter rod 22 are provided with a filter rod groove, which is concave, for installing the filter rod 100. Meanwhile, the first rod-picking wheel 21 and the second rod-picking wheel 22 have light-transmitting channels 23 that communicate with the rod-picking slots. There are several rod-picking slots and light-transmitting channels 23, which are arranged in a ring shape, so that when the light source 42 is turned on, it can irradiate and analyze the composite composition inside the filter rod 100.

[0052] Furthermore, continue to refer to Figures 1-5 The air distribution assembly 3 also includes a second filter cotton 34, which is disposed at the air inlet 321. Specifically, the second filter cotton 34 is fixedly connected to the inner side of the air inlet 321, and a filter cotton pressure plate is fixedly connected to the inner side of the housing 41. The filter cotton pressure plate is fixedly connected to the second filter cotton 34. The second filter cotton 34 can prevent dust from entering the interior of the air distribution wheel 32 from the air inlet 321, thus achieving a dust prevention effect.

[0053] Furthermore, continue to refer to Figures 1-5 The composite filter rod cooling device also includes a sealing ring 5, which is sleeved on the rotating shaft 1. The outer ring of the sealing ring 5 is sealed to the gas distribution wheel 32. Specifically, a bearing 6 is fixedly connected to the inner side of the second rod-taking wheel 22. The bearing 6 is located on the outer side of the rotating shaft 1. When the rotating shaft 1 rotates, the second rod-taking wheel 22 can be driven to rotate through the bearing 6. A sealing ring 5 is provided between the bearing 6 and the gas distribution wheel 32 to prevent lubricating oil from entering the interior of the gas distribution wheel 32 and affecting the irradiation of the light-emitting component 4.

[0054] This embodiment also provides the aforementioned composite filter rod cooling device. The illumination component 4 illuminates the filter rod 100 installed on the rod picking wheel component 2, and the computer processes and analyzes the light to determine whether the composite structure inside the filter rod 100 meets the standards. The external air source passes through the air inlet 321 and the air chamber in sequence and is discharged from the air outlet 322, which can remove the heat dissipated from the inside of the illumination component 4, thus solving the problem that the light source 42 can easily generate a lot of heat during long-term illumination, which affects the detection accuracy of the filter rod 100.
