[0002] Cigarette filter tips are divided into ordinary filter tips and composite filter tips. When producing cigarettes with composite filter tips, since the composite filter tips are a production combination of secondary processing, during the process of the filter tips being launched into the cigarette making machine, broken and incomplete filter tips (hereinafter referred to as broken filter tips) often enter the filter tip magazine of the cigarette making machine. When the broken filter tips are squeezed and deformed during transportation and are taken away by the filter tip cutting drum, they are likely to block and continuously adhere to the suction holes on the filter tip cutting drum, resulting in the filter tip cutting drum being unable to normally suck other normal filter tips. If the broken filter tips are not cleaned in time, it will lead to excessive rejection of cigarettes without filter tips, serious production waste, and at the same time, there is a risk of producing cigarettes without filter tips in the next production process. Therefore, a device is needed to detect broken filter tips and achieve early warning and cleaning. Summary of the Utility Model

[0026] Example

[0027] like Figures 1 to 3 As shown, a filter tip cutting drum wheel broken filter tip detection and cleaning device comprises a filter tip material storehouse 9, a filter tip conveying mechanism 10 is arranged at the discharge port of the filter tip material storehouse 9, a filter tip cutting drum wheel 7 is also arranged at the discharge port of the filter tip material storehouse 9, the filter tip cutting drum wheel 7 is located at the side of the filter tip conveying mechanism 10, the rotary cutting surface of the filter tip cutting drum wheel 7 is tangent to the conveying surface of the conveying belt on the filter tip conveying mechanism 10, wherein a plurality of wheel grooves are evenly arranged on the circumference of the filter tip cutting drum wheel 7, suction holes are arranged on the wheel grooves, the suction holes are collectively connected to an air source generating device, and the air source generating device generates negative pressure at the suction holes, and the filters in the filter tip material storehouse 9 fall from the discharge port onto the filter tip conveying mechanism 10, The filter is delivered to the filter cutting drum 7 through the filter conveying mechanism 10, and the suction hole absorbs and fixes the filter to the wheel groove. The filter cutting drum 7 releases the filter by rotating to a specified position, so that the filter is continuously supplied to the downstream component for rolling cigarettes. Due to the failure of the equipment upstream of the filter conveying, a certain amount of broken filters 71 may exist in the normal filters in the filter material warehouse 9. Although the negative pressure of the filter cutting drum 7 will be temporarily closed in the corresponding mechanical phase in the current technology, the broken filters 71 will continue to be attached to the negative pressure suction hole after being continuously stirred and squeezed in the material warehouse and sucked away by the negative pressure of the filter cutting drum 7, and the broken filters 71 cannot fall off, resulting in the corresponding wheel groove being unable to absorb normal filters in the next rotation.

[0028] Preferably, the utility model further includes a cleaning device, which is arranged on the cigarette making machine base 1. The cleaning device includes a cleaning component and a detection component. The cleaning component is installed on the cigarette making machine base 1, and the detection component is installed on the cleaning component. The cleaning component is arranged on the side of the filter cutting drum 7, and the output port of the cleaning component is aligned with the filter cutting drum 7.

[0029] In some preferred embodiments, the cleaning assembly includes a mounting bracket 3, a gas source device 4, a hollow mounting structure 5, and a cleaning air pipe 6. The mounting bracket 3 is mounted on the cigarette making machine base 1, the gas source device 4 is mounted on the cigarette making machine base 1, the hollow mounting structure 5 is mounted on the mounting bracket 3. One end of the hollow mounting structure 5 is connected to the gas source device 4 through an air delivery pipe, and the other end is connected to the cleaning air pipe 6. The nozzle of the cleaning air pipe 6 is aligned with the end of the wheel groove;

[0030] Specifically, the end of the cleaning air pipe 6 is U-shaped, and the blowing direction of the cleaning air pipe 6 is parallel to the axial direction of the wheel groove;

[0031] In some preferred embodiments, the detection assembly is mounted on the mounting bracket 3, and the detection assembly includes a photoelectric sensor 2;

[0032] Preferably, an audible and visual alarm device 8 is further provided on the filter rod magazine 9. The audible and visual alarm device 8, the photoelectric sensor 2, the gas source device 4 are electrically connected to the PLC control unit of the cigarette equipment and are controlled by the PLC control unit of the cigarette equipment.

[0033] The mounting bracket 3 in the present utility model is not limited to a rigid metal bracket. The mounting bracket 3 is tightly and fixedly mounted on the cigarette making machine base 1. The hollow mounting structure 5 is closely attached below the bracket. The hollow mounting structure 5 includes but is not limited to a rigid metal shell; The photoelectric sensor 2 includes but is not limited to a micro color difference sensor, as long as it can detect the broken filter tips 71 in the wheel groove when the filter tip cutting drum 7 rotates.

[0034] Specific implementation principle: When the reflected light signal received by the photoelectric sensor 2 does not match the set value, it is determined that there are broken filter tips 71 in the wheel groove of the filter tip cutting drum 7. The audible and visual alarm device 8 alarms, and the PLC control unit controls the gas source device 4 to output positive pressure air, which is delivered to the U-shaped cleaning air pipe 6 through the hollow mounting structure 5, and continuously blows air into the wheel groove to remove the broken filter tips 71. The U-shaped cleaning air pipe 6 in the present utility model includes but is not limited to a rigid metal elbow, as long as it can ensure the blowing direction under continuous positive pressure blowing. When the audible and visual alarm device 8 is reset during the lower limit of the alarm duration, the alarm stops, and it is determined that there are no broken filter tips 71. When the alarm duration exceeds the set time upper limit, it is determined that the cleaning of the broken filter tips 71 is abnormal, and the PLC control unit controls the cigarette making machine to stop, reducing the generation of filter tipless cigarette sticks in downstream equipment and reducing the corresponding waste rejection rate.

[0035] The utility model can monitor whether the suction holes are blocked by broken filter tips 71 in the grooves of the filter tip cutting drum 7, remind the operator to observe the production situation of the equipment, and can remove the broken filter tips 71 through the cleaning component, ensure the normal transportation and suction of the filter tips, prevent a large number of unqualified cigarettes from entering the next process, and enable the cigarette-making equipment to resume normal production without stopping, ensure the quality of cigarettes and effectively reduce the consumption of waste cigarettes.

[0036] In summary, for a broken filter tip detection and cleaning device provided by the utility model, during the process of transporting a composite filter tip to a cigarette-making machine, broken and incomplete filter tips often enter the filter tip storage bin of the cigarette-making machine. After the broken filter tips are squeezed and deformed during transportation and taken away by the filter tip cutting drum, they are likely to block and continuously adhere to the suction holes on the filter tip cutting drum, resulting in the filter tip cutting drum being unable to normally suck other normal filter tips. This device can be installed in a narrow space, can detect the broken filter tips on the filter tip cutting drum during the transportation of cigarette filter tips, has an automatic cleaning function, and can remind the operator to observe the production situation of the equipment and the quality of cigarettes through an audible and visual alarm device, prevent filterless cigarettes or broken filter tips from entering the next process during production, and improve production efficiency.
