[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] like Figure 1-Figure 6 As shown, the embodiment of the present application provides a cleaning device for a splicing drum wheel 100, which is used in a cigarette making machine, and is preferably used to clean the splicing drum wheel 100 in the cigarette making machine. Since the cigarette making machine is provided with a plurality of drum wheels, and the outer peripheral surface of the drum wheel is provided with negative pressure air holes, the outer periphery of the drum wheel generates an adsorption force under the drive of the negative pressure device, thereby being able to realize adsorption and rotational transportation of cigarettes, cigarette papers and kraft paper, etc. For the drum wheel for conveying cigarette paper, since the rotation speed of the drum wheel is very fast, the tobacco and tobacco foam in the cigarette are easily thrown out under the action of centrifugal force, so that a certain amount of tobacco and tobacco foam exists in the cigarette making machine. If the tobacco and tobacco foam diffuse to the splicing drum wheel 100 for the splicing process, the tobacco and tobacco foam are rubbed The outer periphery of the splicing drum 100 is adsorbed, and a certain amount of tobacco and cigarette foam accumulate on the outer peripheral surface of the splicing drum 100. In serious cases, the negative pressure vents on the splicing drum 100 may be blocked, resulting in insufficient adsorption of the splicing drum 100 on the tipping paper, which may easily lead to quality defects in the splicing process. In addition, the tipping paper may be easily contaminated with tobacco and cigarette foam by the splicing drum 100, which may have a negative impact on the bonding effect of the tipping paper, reduce the bonding strength of the tipping paper, and also lead to quality defects in the splicing process. The splicing drum 100 cleaning device of the present application is intended to clean the tobacco and cigarette foam on the outer surface of the splicing drum 100, and remove the tobacco and cigarette foam on the splicing drum 100 to avoid the above defects.

[0027] The splicing drum 100 cleaning device includes a connecting frame 3, a nozzle 4 and a first fastener 51. The nozzle 4 is installed on the connecting frame 3 through the first fastener 51. The connecting frame 3 is installed on a preset device, for example, on the frame of a cigarette making machine, so that the nozzle 4 is near the splicing drum 100. Then, an air supply pipe 200 is connected to the nozzle 4, and the splicing drum 100 is blown through the nozzle 4 to remove impurities such as tobacco shreds and tobacco foam on the outer surface of the splicing drum 100, keep the outer surface of the splicing drum 100 clean, ensure the stable adsorption force of the splicing drum 100 on the tipping paper, and prevent the tobacco shreds and tobacco foam on the splicing drum 100 from being transferred to the tipping paper, so that the tipping paper remains clean, which is beneficial to improving the quality of the splicing process steps.

[0028] In this embodiment, a first mounting hole 301 and a second mounting hole 302 are provided on the connecting frame 3, and the cross-sections of the first mounting hole 301 and the second mounting hole 302 are circular, that is, the first mounting hole 301 and the second mounting hole 302 are both circular holes, and the nozzle 4 is arranged in the shape of an elongated round rod, and a jet port 401 and an air inlet 402 are arranged on the nozzle 4, and the air inlet 402 and the jet port 401 are connected, and the jet port 401 is arranged on the outer peripheral side of the nozzle 4, that is, the jet port 401 is arranged on the outer circumferential side wall of the elongated round rod-shaped nozzle 4, and the air supply pipe 200 is connected to the air inlet 402. Under the air supply action of the air supply pipe 200, the air flow is ejected from the jet port 401 of the nozzle 4, and then the outer surface of the splicing drum wheel 100 is sprayed.

[0029] Preferably, the nozzle 4 can be installed in the first mounting hole 301 in a circumferential and axially adjustable manner through the first fastener 51. Since the air jet 401 is arranged on the outer peripheral side of the nozzle 4, the position and direction of the air jet 401 can be adjusted by axially moving the nozzle 4 and circumferentially rotating the nozzle 4. At that time, the connecting frame 3 can also be connected to a preset device such as a frame by using auxiliary parts such as screws and bolts to pass through the second mounting hole 302. Under the action of the circular second mounting hole 302, the connecting frame 3 can be rotated to adjust its posture. In addition, the posture of the nozzle 4 relative to the connecting frame 3 can be adjusted under the action of the first mounting hole 301 and the first fastener 51, so that the direction and position of the air jet 401 on the nozzle 4 can be conveniently adjusted. Therefore, the nozzle 4 can be conveniently adjusted to adjust the spraying position and angle of the splicing drum 100 according to actual conditions, which is beneficial to improving the cleaning effect of the splicing drum 100 and realizing multi-directional cleaning of the splicing drum 100.

[0030] In one embodiment, the air inlet 402 is located on the outer peripheral side of the nozzle 4, so the air inlet 402 and the air jet 401 are both formed on the outer circumferential side wall of the nozzle 4, and an air flow channel 403 is arranged inside the nozzle 4, and the air jet 401 and the air inlet 402 are connected through the air flow channel 403, and the air inlet 402 is used to connect with the air supply pipe 200, and the orientation of the air inlet 402 and the air jet 401 is set according to the spatial layout of the equipment in the cigarette making machine to facilitate the connection and installation of the air supply pipe 200, thereby increasing the convenience and adaptability of the installation of the cleaning device. Preferably, the inner wall of the air inlet 402 can be provided with an internal thread, which is convenient for connection with the air supply pipe 200 by threaded matching, and the assembly is more convenient. The airflow provided by the air supply pipe 200 enters the air flow channel 403 through the air inlet 402, and then is blown onto the twisting drum wheel 100 through the air jet 401.

[0031] More preferably, the airflow channel 403 is extended along the length direction of the nozzle 4, the airflow channel 403 is a cavity with a circular cross-section, the axis of the airflow channel 403 coincides with the axis of the nozzle 4, one end of the airflow channel 403 is open, and the other end of the airflow channel 403 is closed, that is, one end of the airflow channel 403 extends to the vicinity of the end of the corresponding end of the nozzle 4, and the other end of the airflow channel 403 extends to the other end of the nozzle 4 and penetrates outward to communicate with the outside world, and a blocking member 41 is provided on the nozzle 4, and the blocking member 41 is used to block the open end of the airflow channel 403. In this embodiment, the blocking member 41 The sealing member 41 is detachably connected to the nozzle 4 to facilitate the installation and disassembly of the sealing member 41. By disassembling the sealing member 41, the airflow channel 403 in the nozzle 4 can be conveniently observed and inspected. When the air jet 401 is blocked by foreign matter, it is conducive to timely troubleshooting. Preferably, the sealing member 41 can be a screw, which can be screwed into the open end of the airflow channel 403 to seal the end of the airflow channel 403. After the airflow channel 403 is blocked, a closed channel is formed between the air jet 401 and the air inlet 402, so that the airflow provided by the air supply pipe 200 can be smoothly ejected through the air jet 401.

[0032] In this embodiment, the jet port 401 and the air inlet 402 are both close to the closed end of the air flow channel 403. After the connecting frame 3 is installed on a preset device such as a frame through the second mounting hole 302, the jet port 401 and the air inlet 402 are both located near the end of one end of the nozzle 4. Preferably, the jet port 401 is closer to the closed end of the air flow channel 403 than the air inlet 402. In this way, the jet port 401 is relatively closer to the end, which is conducive to the nozzle 4 protruding toward the splicing drum 100. By setting the nozzle 4 to a certain length, it is convenient to arrange it in a small space. Moreover, the air inlet 402 is relatively close to the closed end of the air flow channel 403. When foreign matter is blocked in the air flow channel 403, by removing the blocking member 41 and then increasing the blowing intensity of the air supply pipe 200, the foreign matter in the air flow channel 403 can be discharged from the open end of the air flow channel 403.

[0033] Preferably, the axial direction of the jet port 401 and the axial direction of the air inlet 402 are both the diameter direction of the cross section of the nozzle 4, that is, the jet port 401 and the air inlet 402 both radiate radially outward, and in the circumferential direction of the cross section of the nozzle 4, the axial direction of the jet port 401 and the axial direction of the air inlet 402 are arranged perpendicular to each other. After connecting the air supply pipe 200, the part of the air supply pipe 200 close to the nozzle 4 and the blowing direction of the jet port 401 are in a vertical state, which facilitates the layout of the air supply pipe 200, etc. when the drum wheel 100 is sprayed and rubbed on the side.

[0034] In one example, the first fastener 51 includes a threaded rod, which is a long round rod-shaped structure. An external thread is provided on the outer side of the threaded rod. A first positioning hole 31 is provided on the connecting frame 3. The first positioning hole 31 is connected to the first mounting hole 301. An internal thread is provided in the first positioning hole 31. The threaded rod and the first positioning hole 31 are threadedly matched. The threaded rod can be screwed into the first positioning hole 31 and pressed against the outer peripheral side of the nozzle 4 that is penetrated into the first mounting hole 301, so as to press and limit the nozzle 4 to prevent the nozzle 4 from moving, thereby realizing the installation of the nozzle 4 in the first mounting hole 301. Loosening the threaded rod can release the pressing and limiting of the nozzle 4, so that the nozzle 4 can be adjusted circumferentially and axially in the first mounting hole 301. This installation method has a simple structure and is easy to operate, and is convenient for multi-directional adjustment of the nozzle 4.

[0035] Preferably, the connecting frame 3 is an elongated member, for example, a rectangular member, the first mounting hole 301 is located at one end of the connecting frame 3 in the length direction, and the first mounting hole 301 passes through the opposite sides of the connecting frame 3 at this end. The rectangular connecting frame 3 is convenient for holding and installing the connecting frame 3, and is also convenient for storage.

[0036] More preferably, when the connecting frame 3 is a rectangular parallelepiped component, on a cross section perpendicular to the length direction of the connecting frame 3, the first mounting hole 301 penetrates the two sides of the connecting frame 3 as the shorter sides in the circumferential direction, and the second through hole penetrates the two sides of the connecting frame 3 as the longer sides in the circumferential direction, so that the axial direction of the first mounting hole 301 is perpendicular to the axial direction of the second mounting hole 302. In this way, when the connecting frame 3 is installed on a preset device by using screws or bolts to pass through the second mounting holes 302, the swing axis direction of the connecting frame 3 relative to the preset device and the axial direction of the nozzle 4 are perpendicular to each other. , it is more convenient to adjust the injection angle and position of the jet port 401 on the nozzle 4, and it is also convenient to judge the appearance of the connecting frame 3, which is more convenient during assembly and installation. In this embodiment, after the nozzle 4 is installed in the first mounting hole 301, the nozzle 4 is rotated and adjusted to make the axial direction of the jet port 401 parallel to the axial direction of the second mounting hole 302. In this state, the airflow injection direction of the jet port 401 is perpendicular to the swing direction of the connecting frame 3 relative to the preset device, and the reaction force of the injection will not drive the connecting frame 3 to swing, and the installation stability is higher.

[0037] In this embodiment, the axial direction of the first mounting hole 301 is not perpendicular to the length direction of the connecting frame 3. After the nozzle 4 is installed in the first mounting hole 301, one end of the air outlet 401 of the nozzle 4 is in a posture of protruding outward along the length direction of the connecting frame 3, which is more conducive to the layout of the narrow space in the cigarette making machine.

[0038] The present embodiment also includes a positioning rod 6 and a second fastener 52. The positioning rod 6 can be installed in the second mounting hole 302 in a circumferential and axially adjustable manner through the second fastener 52. The positioning rod 6 can be an axis component of the cigarette making machine itself, or an axis component welded to the cigarette making machine. The second fastener 52 can be a screw. A second positioning hole 32 is provided on the connecting frame 3. The second positioning hole 32 is connected with the second mounting hole 302. An internal thread is provided in the second positioning hole 32. The second fastener 52 can be screwed into the second positioning hole 32 and pressed against the positioning rod 6, thereby realizing the limiting between the connecting frame 3 and the positioning rod 6. After loosening the second fastener 52, the positioning rod 6 can move axially and circumferentially in the second mounting hole 302, thereby facilitating the position and angle adjustment of the connecting frame 3 on the preset device.

[0039] Preferably, there are multiple second mounting holes 302, and the multiple second mounting holes 302 are arranged at intervals along the length direction of the connecting frame 3, further increasing the adjustment dimension of the connecting frame 3 relative to the preset device, further improving the adjustability of the nozzle 4, and improving the installation adaptability and comprehensiveness of cleaning of the rubbing drum 100.

[0040] The working principle of the present application is as follows: the air supply pipe 200 is connected to the air inlet 402 of the nozzle 4, and then the nozzle 4 is installed in the first installation hole 301 through the first fastener 51, and then the connecting frame 3 is installed on the positioning rod 6 of the preset device through the second fastener 52. According to the position on the splicing drum 100 that needs to be cleaned, the first fastener 51 and the second fastener 52 are loosened, and the position and angle of the nozzle 4 relative to the connecting frame 3 and the position and angle of the connecting frame 3 relative to the preset device are adjusted. After the adjustment is completed, the first fastener 51 and the second fastener 52 can be tightened, and then the air supply pipe 200 is started to spray the splicing drum 100.
