Description

Technical Field

[0001] This application relates to the field of cigarette making machine technology, and in particular to a foreign matter blowing mechanism for a cigarette making machine and a cigarette making machine. Background Technology

[0002] A cigarette rolling machine is a device that uses tobacco paper to roll tobacco into finished cigarettes. The machine includes a cigarette feeding unit and a forming unit arranged sequentially. The cigarette feeding unit includes a receiving drum, a cutting drum, a cutting blade assembly, a separating drum, and a merging drum. The receiving drum receives a cigarette twice its length from upstream. The cutting drum cuts the cigarette into two equal-length segments that meet process requirements. The separating drum then transfers the two segments to the merging drum. An external filter supply system places a double-length filter segment into the merging drum, positioned between the two segments. The forming unit includes a closing drum, a forming drum, a rubbing plate, a conveying drum, and a filter-cutting drum. During the transfer of the filter segment and the cigarette to the closing drum, the drum precisely aligns the double-length filter segment and the two cigarette segments, forming a three-part assembly of "cigarette-filter-cigarette". The three sections, once joined together, are conveyed to the joining drum. Through the cooperation of the rubbing plate and the joining drum, the wrapping paper is tightly wrapped around the connection between the filter and the cigarette, forming a filter cigarette of double length. After joining, the double-length filter cigarette is received by the conveying drum and stably conveyed to the filter cigarette cutting drum. The filter cigarette cutting drum cuts the double-length filter cigarette into two filter cigarettes of equal length, thus obtaining the finished cigarette.

[0003] During the process of transferring the cigarette from the converging drum to the closing drum, due to airflow and inertia, foreign objects such as paper scraps and tobacco dust around the cigarette will be scattered onto the closing drum and the wrapping paper that has not yet been wrapped. When the wrapping paper wraps the filter and the cigarette during the subsequent twisting process, it will cover the foreign objects. The presence of foreign objects affects the quality of the finished cigarette and leads to the formation of cigarette dust. Utility Model Content

[0004] Therefore, it is necessary to provide a foreign matter removal mechanism for a cigarette making machine and a cigarette making machine in response to the above problems. The foreign matter removal mechanism removes foreign matter around the cigarette on the converging drum, thereby improving the production quality of finished cigarettes.

[0005] On one hand, a foreign matter removal mechanism for a cigarette rolling machine is provided. The cigarette rolling machine includes a converging drum and a closing drum. The converging drum receives cigarettes, and each cigarette on the converging drum has at least two segments. The at least two segments of the cigarette are spaced apart along a direction parallel to the axial direction of the converging drum. A filter segment is spaced apart between adjacent segments of the cigarette. The closing drum receives the cigarettes and the filter segments on the converging drum and is capable of aligning adjacent segments of the cigarette with the filter segments. The foreign matter removal mechanism is disposed below the converging drum and includes:

[0006] Mounting assembly, the mounting assembly being used to connect to the bracket of the cleaning brush located on the underside of the adjoining drum; and

[0007] A blower assembly connected to the mounting assembly is capable of blowing air onto the cigarette on the converging drum, such that at least a portion of the airflow blown by the blower assembly can flow in the direction from the filter section toward the cigarette to remove foreign matter around the cigarette.

[0008] In one embodiment, a swing member is further included, which is rotatably connected to the mounting assembly. One end of the swing member away from the mounting assembly is connected to the blower assembly. The swing member is capable of swinging downward relative to the mounting assembly to move the blower assembly away from the converging drum, and the swing member is also capable of swinging upward relative to the mounting assembly to move the blower assembly closer to the converging drum.

[0009] In one embodiment, the mounting assembly includes a swing base, a fixing member, and a rotating pin. The swing base is connected to the bracket via the fixing member, and the swing member is rotatably connected to the swing base via the rotating pin.

[0010] In one embodiment, a positioning shaft is further included. The swing seat is provided with a mounting hole. The positioning shaft is disposed in the mounting hole and is connected to the side wall of the mounting hole. The end of the swing member away from the blower assembly is disposed in the mounting hole and is movably sleeved on the outer periphery of the positioning shaft. The swing member is capable of swinging relative to the positioning shaft. The rotating pin is spaced between the blower assembly and the positioning shaft.

[0011] In one embodiment, an adjusting member is further included. A clearance opening is provided on the upper or lower side of the swing seat. The clearance opening connects the mounting hole and the side of the swing seat near the blower assembly. One end of the swing member away from the blower assembly passes through the clearance opening and extends into the mounting hole. The swing seat is provided with an adjusting hole communicating with the clearance opening. The adjusting member is disposed in the adjusting hole, and one end of the adjusting member can abut against the swing member to apply a damping force to the swing member.

[0012] In one embodiment, the blower assembly includes a blower block and a connector. The blower block is disposed on the connector and is connected to an air supply mechanism. The length direction of the connector is parallel to the axial direction of the converging drum. The connector is connected to the end of the swing member away from the mounting assembly. Air outlets are provided on both sides of the blower block located in the length direction of the connector.

[0013] In one embodiment, the blower assembly further includes two air guide hoods, both of which are disposed on the connector. The two air guide hoods are spaced apart along the length of the connector, and the blower block is disposed between the two air guide hoods. An air guide channel is provided between the air guide hoods and the connector, and the air guide channel communicates with the air outlet.

[0014] In one embodiment, the device further includes a detector and an alarm communicatively connected to the detector. The detector is used to detect the swing displacement of the swinging member, and the alarm emits an alarm signal when the detector detects that the swing displacement of the swinging member exceeds a set threshold.

[0015] In one embodiment, a fastener is also included, wherein a first fastening hole is provided on the upper side of the swing seat, and a second fastening hole is provided on the detector, and one end of the fastener passes through the second fastening hole and is tightened in the first fastening hole.

[0016] On the other hand, a cigarette making machine is provided, wherein the cigarette on the converging drum has at least two segments, the at least two segments of the cigarette are spaced apart along a direction parallel to the axial direction of the converging drum, a filter segment is spaced apart between adjacent segments of the cigarette, a closing drum is disposed on one side of the converging drum, the closing drum is capable of bringing the cigarette and the filter segment on the converging drum closer and aligning adjacent segments of the cigarette and the filter segment, and a foreign matter blowing mechanism is disposed below the converging drum.

[0017] The foreign matter removal mechanism of the aforementioned cigarette machine blows air around the cigarette on the converging drum via a blowing assembly. This allows at least a portion of the airflow from the blowing assembly to flow in the direction from the filter section towards the cigarette. Consequently, foreign matter such as scraps of paper and tobacco dust around the cigarette on the converging drum is blown away by the airflow from the opposite sides of the two sections of the cigarette. During the cigarette's transport to the closing drum, this effectively reduces the amount of foreign matter on the converging drum that drifts onto the closing drum and onto the unwrapped paper in subsequent processes, thereby improving the production quality of the finished cigarette and reducing the probability of dust accumulation. Since the foreign matter removal mechanism is located below the converging drum, and the mounting assembly is connected to the bracket of the cleaning brush on the lower side of the closing drum, this bracket provides overall support for the mechanism, making efficient use of the internal space of the cigarette machine and facilitating its installation.

[0031] See Figure 1 and Figure 2 , Figure 1 A schematic diagram showing the distribution of the converging drum, the approaching drum, and the cleaning brush in some embodiments of this application is shown; Figure 2A perspective view is shown of a foreign matter removal mechanism of some embodiments of this application mounted on a cleaning brush bracket. One embodiment of this application provides a foreign matter removal mechanism (hereinafter referred to as the foreign matter removal mechanism) for a cigarette machine, which is applied in a cigarette machine. The cigarette machine includes a converging drum 400, a closing drum 500 rotatably disposed on one side of the converging drum 400, and a cleaning brush 100 disposed below the closing drum 500. The cigarette on the converging drum 400 has at least two segments, which are spaced apart along a direction parallel to the axial direction of the converging drum 400, and a filter segment is disposed between adjacent cigarette segments. The closing drum 500 is capable of receiving the cigarette and the filter segment on the converging drum 400, and is capable of aligning adjacent cigarette segments with the filter segment. In this example, the converging drum 400 is capable of receiving cigarettes conveyed by the separating drum of the cigarette rolling machine. The converging drum 400 is circumferentially provided with a cigarette slot (not shown in the figure) and a filter slot (not shown in the figure). There are at least two cigarette slots, which are spaced apart along a direction parallel to the axial direction of the converging drum 400. A filter slot is provided between two adjacent cigarette slots in a direction parallel to the axial direction of the converging drum 400. The cigarette slot is used to accommodate the cigarette, and the filter slot is used to accommodate a filter segment of twice its length. In actual implementation, the converging drum 400 receives two cigarette segments from the separating drum of the cigarette machine. The two segments are respectively adsorbed into two adjacent cigarette slots in a direction parallel to the axial direction of the converging drum 400, but the cigarettes in the two slots are separate at this time. Simultaneously, the converging drum 400 receives a filter segment of twice its length from the mouthpiece supply system. The filter segment is adsorbed into the filter slot located between the two cigarette slots. The converging drum 500 has features for... A pusher component moves the cigarette in the cigarette slot along a direction parallel to the axial direction of the converging drum 400. During the process of the converging drum 400 transmitting the cigarette and filter section to the approaching drum 500, the pusher component on the approaching drum 500 precisely and smoothly moves the two cigarette sections along a direction parallel to the axial direction of the converging drum 400 until the end faces of the two cigarettes are in close contact with the two ends of the twice-length filter section, thus obtaining a three-section assembly of "cigarette-filter section-cigarette". The approaching drum 500 has a circumferentially arranged receiving groove for accommodating the three-section assembly of "cigarette-filter section-cigarette", and the receiving groove has an air intake. The three-section assembly of "cigarette-filter section-cigarette" is adsorbed into the receiving groove through the air intake. A cleaning brush 100 is located below the approaching drum 500 and is in circumferential contact with the approaching drum 500. When the approach drum 500 rotates, the cleaning brush 100 rotates relative to the approach drum 500, so that the brush body of the cleaning brush 100 cleans the surface of the approach drum 500, preventing foreign objects such as tobacco from adhering to the inhalation part and causing the three-section assembly of "cigarette-filter section-cigarette" to fall off the approach drum 500.A foreign object removal mechanism 200 is disposed below the converging drum 400. The foreign object removal mechanism 200 includes a mounting assembly and a blowing assembly. The mounting assembly is connected to a bracket 101 of a cleaning brush 100 located near the lower side of the converging drum 400. The blowing assembly is connected to the mounting assembly and is capable of blowing air onto the cigarette on the converging drum 400, such that at least a portion of the airflow blown by the blowing assembly flows in a direction from the filter section towards the cigarette to remove foreign objects around the cigarette.

[0032] Understandably, after the tobacco is rolled into cigarettes, it is conveyed to the converging drum 400. At the same time as the converging drum 400 receives the cigarettes, it also receives a filter segment of twice the length from the mouthpiece supply system. During the process of the converging drum 400 conveying the cigarettes and filter segments to the approaching drum 500, the pushing component of the approaching drum 500 moves the two cigarette segments precisely and smoothly along a direction parallel to the axis of the converging drum 400 until the end faces of the two cigarettes are in close contact with the two ends of the double-length filter segment, thus forming a combination of "cigarette-filter segment-cigarette". During the process of transferring the cigarette and filter section on the converging drum 400 to the approaching drum 500, due to airflow and inertia, foreign objects such as paper scraps or tobacco dust around the cigarette will be scattered onto the approaching drum 500 and the wrapping paper that has not yet been wrapped. In the subsequent twisting stage, the wrapping paper will also wrap the foreign objects when wrapping the filter and cigarette. The presence of foreign objects affects the production quality of the finished cigarettes.

[0033] The foreign matter removal mechanism 200 of this structure blows air around the cigarette on the converging drum 400 through the blowing assembly, so that at least part of the airflow blown by the blowing assembly can flow in the direction from the filter section to the cigarette. In this way, foreign matter such as paper scraps and tobacco dust around the cigarette on the converging drum 400 can be blown away by the airflow from the opposite sides of the two cigarette sections. During the process of the cigarette and filter section being transferred to the approaching drum 500, it can effectively reduce the foreign matter on the converging drum 400 from drifting onto the approaching drum 500 and the unwrapped wrapping paper in subsequent processes, thereby improving the production quality of finished cigarettes and reducing the probability of the formation of cigarette dust. Since the foreign object blowing mechanism 200 is located below the converging drum 400 and the mounting assembly is connected to the bracket 101 of the cleaning brush 100 near the lower side of the converging drum 500, the bracket 101 provides overall support for the foreign object blowing mechanism 200, making reasonable use of the internal space of the cigarette machine and facilitating the installation of the foreign object blowing mechanism 200.

[0034] In actual implementation, for the cigarette located on the converging drum 400, waste bins are provided on both sides of the two cigarette sections facing away from each other. Therefore, when foreign objects flow along the filter section in the direction of the cigarette with the airflow, they can be collected through the waste bins.

[0035] Combination Figure 2 and Figure 3The foreign object removal mechanism 200 also includes a swing member 2, which is rotatably connected to the mounting assembly. The end of the swing member 2 furthest from the mounting assembly is connected to the blowing assembly. The swing member 2 can swing downwards relative to the mounting assembly to move the blowing assembly away from the converging drum 400, and it can also swing upwards relative to the mounting assembly to move the blowing assembly closer to the converging drum 400. Because the foreign object removal mechanism 200 is located below the converging drum 400, during the transmission of the cigarette and filter segments to the converging drum 500, blockages may occur on the converging drum 400, resulting in a large accumulation of cigarettes and filter segments between the converging drum 400 and the blowing assembly. The swing component 2 is rotatably connected to the mounting assembly. When the cigarette and filter segments become blocked on the converging drum 400, the swing component 2 can be swung downward relative to the mounting assembly, causing the blowing assembly to move downward away from the converging drum 400. This increases the distance between the blowing assembly and the converging drum 400, making it easier to clean the accumulated cigarette and filter segments. After the accumulated cigarette and filter segments are cleaned, the swing component is swung upward relative to the mounting assembly, causing the blowing assembly to move closer to the converging drum 400, thus resetting the blowing assembly and allowing the foreign object blowing mechanism 200 to function normally.

[0036] See Figure 2 and Figure 3 The mounting assembly includes a swing base 1, a fixing member, and a rotating pin. The swing base 1 is connected to the bracket 101 via the fixing member, and the swing member 2 is rotatably connected to the swing base 1 via the rotating pin. This design allows the swing member 2 to rotate relative to the swing base 1 about the axis of the rotating pin, thereby enabling the blower assembly to move towards or away from the converging drum 400. In actual implementation, combined with... Figure 4 The swinging component 2 is provided with a rotating hole 21, and a rotating pin is provided through the rotating hole 21.

[0037] In this example, the fixing component includes a fixed shaft 6 connected to the swing seat 1. One end of the fixed shaft 6 is provided with an external thread, and the bracket 101 is provided with a threaded hole. The end of the fixed shaft 6 with the external thread is fitted into the threaded hole, so that the fixed shaft 6 is connected to the bracket 101.

[0038] To facilitate the assembly of the fixed shaft 6 onto the bracket 101, combined with Figure 5 The fixed shaft 6 includes a first section 61 and a second section 62 distributed sequentially along its own axial direction. The first section 61 is a round bar with external threads, and the second section 62 is a hexagonal bar. This allows a wrench to be engaged with the second section 62 when connecting the fixed shaft 6 to the bracket 101, facilitating the assembly of the fixed shaft 6 onto the bracket 101. The threaded connection between the fixed shaft 6 and the bracket 101 makes the replacement and maintenance of the foreign object blowing mechanism 200 more convenient.

[0039] The fastener also includes locking screws (not shown in the figure), combined with Figure 3 One end of the swing seat 1 is provided with a notch 13 communicating with the fixing hole 12, so that the swing seat 1 forms two clamping parts 15 distributed vertically. Both clamping parts 15 are provided with locking holes. The locking screw can pass through the locking hole on one clamping part 15 and be tightened in the locking hole 14 of the other clamping part 15, thereby locking the fixed shaft 6 in the swing seat 1. Because the notch 13 is provided on the swing seat 1, there is enough space in the fixing hole 12 to accommodate the fixed shaft 6, which facilitates the assembly of the fixed shaft 6 and the swing seat 1. After the fixed shaft 6 is placed in the fixing hole 12, one end of the locking screw is passed through the locking hole on one clamping part 15 and tightened in the locking hole 14 of the other clamping part 15, so that the two clamping parts 15 can press against the fixed shaft 6, preventing the swing seat 1 from moving relative to the fixed shaft 6.

[0040] In this example, the fixing hole 12 is a round hole with a diameter of 18mm. In actual implementation, the structure and size of the fixing hole 12 can be flexibly adjusted as needed.

[0041] The fixed shaft 6 is made of Q235A steel. In actual implementation, the material of the fixed shaft 6 can be flexibly selected as needed. No specific restrictions are placed on the material of the fixed shaft 6 here.

[0042] In this example, the fixed shaft 6 also includes a third segment 63. Along the axial direction of the fixed shaft 6, the third segment 63 is located between the first segment 61 and the second segment 62. The third segment 63 is a round bar, and at least a portion of the third segment 63 protrudes from the side of the swing seat 1 facing away from the support 101.

[0043] Of course, in other examples, the fastener can also be other structures, that is, the swing seat 1 can also be connected to the bracket 101 through other structures, such as welding the swing seat 1 to the bracket 101. Here, no specific limitation is made on the connection structure between the swing seat 1 and the bracket 101. Any structure that can fix the swing seat 1 to the bracket 101 is acceptable.

[0044] Combination Figure 2The foreign object blowing mechanism 200 also includes a positioning shaft 8. A mounting hole 17 is provided in the swing seat 1, and the positioning shaft 8 is disposed in the mounting hole 17 and connected to the side wall of the mounting hole 17. The end of the swing member 2 furthest from the blowing assembly is disposed in the mounting hole 17 and movably sleeved on the outer periphery of the positioning shaft 8, allowing the swing member 2 to swing relative to the positioning shaft 8. A rotating pin is spaced between the blowing assembly and the positioning shaft 8. Providing a mounting hole 17 in the swing seat 1 allows one end of the swing member 2 to extend into the swing seat 1, improving the structural compactness of the swing member 2 and the swing seat 1. Furthermore, since the end of the swing member 2 furthest from the blowing assembly is movably sleeved on the outer periphery of the positioning shaft 8, when the swing member 2 rotates around the axis of the rotating pin, the positioning shaft 8 can position the swing member 2, improving the stability of the swing member 2's swing.

[0045] Furthermore, the foreign object blowing mechanism 200 also includes an adjusting member 10, and a clearance opening 11 is provided on the upper or lower side of the swing seat 1. In this example, the clearance opening 11 is provided on the lower side of the swing seat 1. The clearance opening 11 connects the mounting hole 17 and the side of the swing seat 1 near the blowing assembly. The end of the swing member 2 away from the blowing assembly passes through the clearance opening 11 and extends into the mounting hole 17. The swing seat 1 is provided with an adjusting hole 18 communicating with the clearance opening 11. The adjusting member 10 is disposed in the adjusting hole 18, and one end of the adjusting member 10 can abut against the swing member 2 to apply a damping force to the swing member 2. In this example, the adjusting hole 18 is a threaded hole, and the adjusting member 10 is a threaded member. The adjusting member 10 is screwed into the adjusting hole 18. By rotating the adjusting member 10 in the adjusting hole 18, the clamping force of one end of the adjusting member 10 against the swing member 2 can be adjusted, thereby applying different magnitudes of damping force to the swing member 2 through the adjusting member 10. The adjusting component 10 applies a damping force to the swing component 2. When the cigarette and filter sections accumulate between the converging drum 400 and the blowing assembly, and when the pressure applied to the swing component 2 by the cigarette and filter sections exceeds the set pressure, the swing component 2 can swing downward relative to the swing seat 1. After clearing the accumulated cigarette and filter sections, the swing component will swing downward relative to the swing seat 1 to drive the blowing assembly to reset. Because the adjusting component 10 applies a damping force to the swing component 2, the position of the swing component 2 is fixed under the action of the damping force, preventing the swing component 2 from automatically swinging downward due to its own weight after reset.

[0046] It should be noted that the adjusting hole 18 is not limited to a threaded hole. In other examples, the adjusting hole 18 can also be a smooth hole. When the adjusting hole 18 is a smooth hole, the adjusting member 10 can be an elastic member with the ability to elastically deform. The size of the adjusting member 10 is set to be larger than the size of the adjusting hole 18 so that the adjusting member 10 can be pressed into the adjusting hole 18. By adjusting the length of the adjusting member 10 extending outside the adjusting hole 18, the magnitude of the damping force applied by the adjusting member 10 to the swing member 2 can be adjusted. In this application, the structure of the adjusting hole 18 is not specifically limited.

[0047] In some embodiments, see Figure 2 The blowing assembly includes a blowing block 4 and a connector 3. The blowing block 4 is mounted on the connector 3 and is connected to the air supply mechanism. In actual implementation, the blowing block 4 is connected to the air supply mechanism via a vent pipe. To facilitate the connection of the vent pipe, a connector 7 is provided on the blowing block. One end of the vent pipe is connected to the connector 7, and the other end is connected to the air supply mechanism. The length direction of the connector 3 is parallel to the axial direction of the converging drum 400. The connector 3 is connected to the end of the swing member 2 away from the mounting assembly. Air outlets 41 are provided on both sides of the blowing block 4 along the length direction of the connector 3. It can be understood that the blowing block 4 has a hollow structure. The air supply mechanism blows gas into the blowing holes, and the blowing block 4 blows air out from the blowing holes on both sides, allowing the airflow to flow in the direction from the filter section towards the cigarette to remove foreign objects around the cigarette. The connector 3 provides support for the blowing block 4 and facilitates its installation. In this example, the air supply mechanism is the air circuit system of the cigarette machine, which makes the foreign object blowing mechanism 200 more convenient to use as it does not need to be connected to an external air source of the cigarette machine.

[0048] In actual implementation, the swinging component 2 is connected to the connecting component 3 via a connector. In this example, combined with... Figure 4 The swing component 2 has a connection hole 22 at the end away from the mounting component, and one end of the adapter passes through the connection hole 22 and is set in the connector 3 to realize the connection between the swing component 2 and the connector 3.

[0049] To improve the removal of foreign objects, the blowing assembly also includes two air guide hoods 5, both of which are mounted on the connector 3. The two air guide hoods 5 are spaced apart along the length of the connector 3, and the blowing block 4 is positioned between the two air guide hoods 5. An air guide channel 300 is provided between the air guide hoods 5 and the connector 3, and the air guide channel 300 is connected to the air outlet 41. In this way, the airflow blown out from the blowing block 4 can be guided by the air guide channel 300, so that the airflow can be more concentrated and blown around the cigarette stick, thereby increasing the blowing force.

[0050] In actual implementation, the blower block 4 has a dimension between the two sides of the blower hole that is greater than the length of the filter section on the converging drum 400.

[0051] In some embodiments, see further reference. Figure 2The foreign object removal mechanism 200 also includes a detector 9 and an alarm connected in communication with the detector 9. The detector 9 is used to detect the swing displacement of the swing member 2. When the detector 9 detects that the swing displacement of the swing member 2 exceeds a set threshold, the alarm sounds an alarm signal. It is understood that when a large number of cigarettes and filter segments accumulate between the converging drum 400 and the blowing assembly, the cigarettes and filter segments will push against the swing member 2, causing the swing member 2 and the blowing assembly to rotate downwards. Therefore, when the swing displacement of the swing member 2 exceeds the set threshold, the cigarettes and filter segments become blocked on the converging drum 400, and the detector 9 triggers the alarm to sound an alarm signal, reminding the operator to stop the machine for repair.

[0052] In this example, detector 9 is a proximity switch. When the cigarette and filter sections on the converging drum 400 are not blocked, the distance between detector 9 and the swinging member 2 is relatively close, so detector 9 can always detect the swinging member 2, and the alarm is not triggered (i.e., the alarm does not emit an alarm signal). When the cigarette and filter sections on the converging drum 400 are blocked, the swinging member 2 is pushed and swung downward by the accumulated cigarette and filter sections, so the swinging member 2 will move away from detector 9, making it undetectable by detector 9. That is, detector 9 detects that the swing displacement of the swinging member 2 exceeds the set threshold, at which point the alarm is triggered and emits an alarm signal.

[0053] It should be noted that detector 9 is not limited to a proximity switch; it can also be a photoelectric sensor, ultrasonic sensor, vision sensor, or ranging sensor, etc.

[0054] The foreign object blowing mechanism 200 also includes fasteners (not shown in the figure). A first fastening hole 16 is provided on the upper side of the swing base 1, and a second fastening hole is provided on the detector 9. One end of the fastener passes through the second fastening hole and is tightened into the first fastening hole 16. The cooperation between the fastener and the first and second fastening holes allows the detector 9 to be mounted on the swing base 1, facilitating its installation. Furthermore, in actual implementation, the position of the detector 9 can be adjusted by adjusting the tightness of the fasteners on the swing component 2, thereby fine-tuning the distance between the detector 9 and the swing component 2. In this example, four first fastening holes 16 are provided, and the four first fastening holes 16 are distributed at intervals along the width direction of the swing. Four second fastening holes are also provided, and the first fastening holes 16 and the second fastening holes correspond one-to-one. In actual implementation, the detector 9 is locked on the swing base 1 by four fasteners. Each fastener corresponds to one first fastening hole 16 and one second fastening hole. The fastener passes through the corresponding second fastening hole and is tightened in the corresponding first fastening hole 16, so that the detector 9 is installed on the swing base 1.

[0055] It should be noted that the detector 9 is not limited to being installed on the swing base 1. The detector 9 can also be installed on other components, such as by setting an additional fixing bracket above the swing component 2 and installing the detector 9 through the fixing bracket.

[0056] This type of cigarette rolling machine blows air around the cigarette on the converging drum 400 through the blowing assembly. At least part of the airflow blown by the blowing assembly can flow in the direction from the filter section to the cigarette. In this way, foreign objects such as scraps of paper and tobacco dust around the cigarette on the converging drum 400 can be blown away by the airflow from the opposite sides of the two sections of the cigarette. During the process of the cigarette being conveyed to the closing drum 500, it can effectively reduce the foreign objects on the converging drum 400 from drifting onto the closing drum 500 and the unwrapped wrapping paper in subsequent processes, thereby improving the production quality of the finished cigarette and reducing the probability of the formation of cigarette dust.

[0057] 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.

[0058] 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 protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
