[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the solution will be further described in detail below in conjunction with specific embodiments.

[0030] like Figures 1 to 5 As shown, an embodiment of the present invention provides a cigarette rejection device for a splicing drum wheel of a cigarette making machine, which includes an air blowing block 21, an electromagnetic valve 41, a controller, and an air supply device. The air blowing block 21 is arranged at the negative pressure vacuum opening in the splicing drum wheel valve core, and the air blowing block is relatively provided with a first protrusion 22 and a second protrusion 24; the first protrusion is provided with a first air blowing hole 221, and the second protrusion is provided with a second air blowing hole 241, and the axes of the first air blowing hole and the second air blowing hole are both perpendicular to the air blowing block; the top surfaces of the first protrusion 21 and the second protrusion 24 are respectively used to cover the two air suction holes at the bottom of the splicing drum wheel cigarette receiving groove 13, and the first air blowing hole and The second air blowing hole is connected to the two air suction holes in a one-to-one correspondence; the air blowing block is provided with a connecting hole 23 connecting the first air blowing hole and the second air blowing hole; the solenoid valve is a two-position three-way valve, one end of the solenoid valve 41 is connected to the air supply device through an air supply pipeline, and the other end of the solenoid valve 41 is connected to a first pipeline 51 and a second pipeline 52, and the first pipeline and the second pipeline are respectively connected to the connecting hole; a round block is provided in the second pipeline 52, and an air vent coaxial with the second pipeline is provided on the round block; the controller is used to be electrically connected to the V-valve opener and closeer of the twisting drum wheel 11, and the solenoid valve is electrically connected to the controller. It can be understood that the control system of the cigarette making machine can also send the V-valve opening and closing signal directly to the controller; the air suction hole is connected to the negative pressure air suction area 12; Figure 1 The arrow in the figure indicates the rotation direction of the smoke receiving groove.

[0031] The cigarette rejection device for the twisting drum of a cigarette making machine provided in an embodiment of the present invention utilizes the V-valve opening and closing control system of the cigarette making machine to send an opening and closing signal of the V-valve to a controller, that is, when the cigarette making machine is turned on, the V-valve opening and closing control system sends an opening signal of the V-valve to the controller, and when the cigarette making machine is stopped, the V-valve opening and closing control system sends a closing signal of the V-valve to the controller. When the controller receives the opening or closing signal of the V-valve, it controls the solenoid valve to operate, so that the first pipeline 51 is connected with the first air blowing hole 221 and the second air blowing hole 241 through the connecting hole. When the cigarette receiving groove 13 rotates to the position of the two protrusions, When the top surface is covered with the air suction holes, the adsorption force on cigarettes in the cigarette holding groove 31 is relatively small. At this time, the gas blown out by the first air hole and the second air hole can conveniently blow off the unqualified double-length cigarettes adsorbed on the top opening of the cigarette holding groove, thereby realizing the removal of cigarettes, thereby being able to remove the waste cigarettes at the splicing drum when the cigarette making machine is started, and also being able to remove the waste cigarettes at the splicing drum when the cigarette making machine is stopped, thereby making it possible to laser punch cigarettes that normally pass through the cigarette making machine when it is working, and also avoiding the cigarettes retained here from being ignited due to frequent punching, which better ensures the quality of cigarettes and reduces the fire hazard. Furthermore, when the first pipeline 51 is shut off from being communicated with the first and second blowing holes, the controller communicates the second pipeline 52 with the first and second blowing holes 221 and 241 through the solenoid valve, thereby utilizing the vent holes on the round block to make the airflow in the second pipeline relatively weak, thereby avoiding excessive airflow, and utilizing the airflow to better avoid the inhaled cigarette dust from blocking the first and second blowing holes, thereby achieving the self-cleaning function, saving gas consumption, and not affecting the cigarette receiving groove to absorb cigarettes. It is understandable that, when the controller receives the opening or closing signal of the V-shaped valve, the controller will control the solenoid valve to operate for a positive pressure blow, that is, when the cigarette making machine is turned on, the controller will control the solenoid valve to operate for a positive pressure blow, and when the cigarette making machine is turned off, the controller will control the solenoid valve to operate for a positive pressure blow to remove unqualified double-length cigarettes absorbed at the top opening of the cigarette receiving groove.

[0032] like Figure 5 As shown, the gas supply device is a gas source 42 and a gas storage tank 43 connected to the gas source, and the gas storage tank is connected to the solenoid valve through the gas supply pipeline.

[0033] Preferably, the gas supply pipeline is provided with a pressure reducing valve 44. It is understandable that the gas supply pipeline may be provided with a switch valve electrically connected to the controller, and the controller controls the opening and closing of the switch valve to control the on-off of the gas supply pipeline.

[0034] Furthermore, a first throttle valve 45 is provided on the first pipeline, and a second throttle valve 46 is provided on the second pipeline.

[0035] Specifically, the round block is a copper block. With this solution, it is possible to avoid excessive airflow in the first blowing hole 221 and the second blowing hole 241, which may affect the cigarette receiving groove of the rubbing drum wheel from adsorbing cigarettes. At this time, the blowing can prevent the first blowing hole and the second blowing hole from being blocked, and has a cleaning function, and also saves gas consumption.

[0036] Preferably, the diameters of the first blowing hole and the second blowing hole are the same.

[0037] Specifically, the diameter of the first blowing hole 221 is 1.5mm to 2.5mm. The diameter of the first blowing hole 221 can be preferably 2mm to achieve a better effect of blowing off the cigarette. It is understandable that since the apertures of the first blowing hole and the second blowing hole are relatively small, but there are a lot of cigarette dust at the smoke receiving groove, it is easy to block the first blowing hole 221 and the second blowing hole 241, especially when the first pipeline is turned off, the first blowing hole and the second blowing hole will lose pressure instantly, and the inhaled cigarette dust may block the first blowing hole 221 and the second blowing hole 241. Considering the possibility of this phenomenon, when the first pipeline 51 is turned off, the second pipeline 52 is connected to the first blowing hole and the second blowing hole through the two-position three-way solenoid valve 41, so that there is a weak blowing in the first blowing hole and the second blowing hole, and a circulating airflow is formed at the valve core to bring the cigarette dust into the negative pressure air duct to avoid the first blowing hole and the second blowing hole from being blocked.

[0038] Furthermore, the cigarette-removing device for the rubbing drum of a cigarette-making machine provided in an embodiment of the present invention further includes a time delay relay electrically connected to the controller, and the time delay relay is arranged between the controller and the solenoid valve. With this technical solution, the adjustability of the removal time can be satisfied. After the V-valve opening and closing control system sends the opening and closing signal of the V-valve to the controller, the time delay relay is used to set a suitable removal working time, so that after receiving the V-valve opening and closing signal, the controller controls the solenoid valve 41 to operate after the delay of the time delay relay, so that the first blowing hole and the second blowing hole start blowing to remove the waste cigarettes in the startup stage of the cigarette-making machine, and blow away the waste cigarettes at the end when the cigarette-making machine is shut down, so as to ensure the product quality when the cigarette-making machine is started and shut down.

[0039] In order to facilitate the maintenance and replacement of the blowing block, the blowing block 21 is detachably connected to the valve core of the splicing drum wheel 11 .

[0040] Furthermore, the air blowing block 21 is provided with two mounting holes 25 for screws to pass through, so that the air blowing block and the rubbing drum valve core can be conveniently connected by screws.

[0041] like Figure 2As shown, it can be understood that the first protrusion 22 and the second protrusion 24 are relatively arranged at the two ends of the blowing block and can jointly form a U-shaped structure; the top surface of the two protrusions is flush with the valve core surface, that is, it is in contact with the bottom of the smoke receiving groove; the top surface of the two protrusions can cover the suction holes in the smoke receiving groove, that is, the area of ​​the top surface of the protrusion is equal to or greater than the area of ​​the suction holes in the smoke receiving groove of the twisting drum, which plays a role in isolating the negative pressure suction in the smoke receiving groove. When the cigarette on the twisting drum 11 approaches the blowing block, the two protrusions gradually cover the suction holes, so that the negative pressure suction of the cigarette in the smoke receiving groove will gradually decrease. When the cigarette on the twisting drum leaves the blowing block, the two protrusions will gradually move away from the suction holes, and the negative pressure suction of the cigarette will gradually increase to normal negative pressure suction. When the cigarettes on the splicing drum pass through the blowing block, the negative pressure suction that adsorbs the cigarettes is minimized due to the covering effect of the convex block on the suction holes. At this time, only a small positive pressure blowing is required in the two blowing holes to blow the cigarettes to be removed from the splicing drum. This will not affect the normal adsorption of cigarettes by the cigarette receiving groove and can achieve the purpose of removing cigarettes, thereby being able to remove the discontinuous cigarette flow in the startup stage, ensuring that qualified cigarettes are stably handed over without confusion when they reach the laser punching wheel.

[0042] The cigarette rejection device of the cigarette splicing drum wheel of the cigarette making machine provided in the embodiment of the present invention has a simple structure, low cost and complete functions, has a self-cleaning function, is maintenance-free, and can reduce labor intensity; it makes up for the defect that the cigarette splicing drum wheel of the ZJ17 cigarette making machine has no rejection device, and significantly improves product quality and equipment efficiency; for the ZJ17 cigarette making machine equipped with a laser punching device, it can effectively reduce the fire hazard caused by cigarette jamming at the laser punching point of the equipment, thereby enhancing safety protection.

[0043] The above are only preferred embodiments of the present invention. It should be pointed out that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Moreover, after reading the contents of the present invention, relevant technical personnel in the field may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
