[0002] Photoelectric switches are common components on tobacco logistics conveying equipment, typically installed at key locations. They detect the position of the material being conveyed on the conveyor and control its operation or shutdown. This ensures the accuracy, timeliness, and reliability of material delivery, enhances equipment automation, ensures coordinated start-up and shutdown of upstream and downstream equipment, improves conveying efficiency, and reduces equipment failure rates.

[0003] Existing photoelectric switches used in tobacco logistics conveying mostly employ mirror reflection or diffuse reflection. In actual production and use, dust accumulates on the photoelectric switches and reflectors due to the influence of the environment, conveyed materials, and mechanical equipment. This affects the accuracy of the photoelectric switches, leading to blockages and damage, seriously impacting production efficiency and product quality. Traditional manual cleaning methods are labor-intensive and prone to omissions. Improper manual operation can easily cause the photoelectric switches to shift, affecting the accuracy of detection positions.

[0030] like Figures 1 to 2 As shown, an embodiment of the present invention provides a cleaning device for a photoelectric switch of a cigarette making device, comprising: a purge component, a fixing component 3 and a dust collecting component 4.

[0031] The purge assembly includes a positive pressure purge part 1 and a negative pressure recovery part 2. The positive pressure purge part 1 is arranged at the top of the photoelectric switch 5, and the negative pressure recovery part 2 is arranged at the bottom of the photoelectric switch 5. The positive pressure purge part 1 is used to purge the lens 51 of the photoelectric switch 5, and the negative pressure recovery part 2 is used to recover high-pressure airflow and dust; the fixing assembly 3 is mounted on the outside of the positive pressure purge part 1 and the negative pressure recovery part 2.

[0032] The dust collecting assembly 4 is communicated with the negative pressure recovery part 2 .

[0033] Specifically, the positive pressure purge part 1 and the negative pressure recovery part 2 are both made of aluminum alloy, which is light, strong, small in size, and does not affect the installation of the photoelectric switch 5.

[0034] The positive pressure purge part 1 and the negative pressure recovery part 2 are both in contact with the photoelectric switch 5, and the lengths of the positive pressure purge part 1 and the negative pressure recovery part 2 are both greater than the length of the photoelectric switch 5, so that at least part of the positive pressure purge part 1 and the negative pressure recovery part 2 are both located outside the photoelectric switch 5, so that the high-pressure airflow derived from the positive pressure purge part 1 purges the lens 51 of the photoelectric switch 5, thereby keeping the lens 51 of the photoelectric switch 5 clean.

[0035] The dust and airflow are recovered by the negative pressure recovery part 2 , so that the dust collection component 4 collects the dust, and the lens 51 of the photoelectric switch 5 is kept clean.

[0036] Furthermore, the photoelectric switch 5 , the positive pressure purge part 1 and the negative pressure recovery part 2 are fixed respectively by the fixing assembly 3 , so that the positive pressure purge part 1 and the negative pressure recovery part 2 can work stably.

[0037] The present invention arranges a positive pressure purge unit 1 on the top of a photoelectric switch 5, a negative pressure recovery unit 2 on the bottom of the photoelectric switch 5, and a fixing assembly 3 sleeved on the outside of the positive pressure purge unit 1 and the negative pressure recovery unit 2; and connects the dust collection assembly 4 to the negative pressure recovery unit 2. The positive pressure purge unit 1 of the present invention purges the lens 51 of the photoelectric switch 5, and recovers dust and airflow through the negative pressure recovery unit 2, thereby allowing the dust collection assembly 4 to collect dust, keeping the lens 51 of the photoelectric switch 5 clean. This ensures the effectiveness and reliability of photoelectric detection, improves equipment efficiency and production efficiency, reduces the labor intensity of cleaning personnel, and prevents dust from falling onto the lens 51 of the photoelectric switch 5 again, solving the problems of omissions and safety hazards in traditional manual cleaning.

[0038] In one embodiment of the cleaning device of the photoelectric switch of the cigarette making equipment of the present invention, as Figure 1 As shown, the positive pressure purge unit 1 includes a positive pressure air chamber 11 and a first air guide tube 12. A first air guide hole (not shown in the figure) is provided inside the positive pressure air chamber 11. The first air guide tube 12 is connected to the first end of the positive pressure air chamber 11 and communicates with the first air guide hole. The bottom of the positive pressure air chamber 11 abuts against the photoelectric switch 5, and the second end of the positive pressure air chamber 11 extends out of the photoelectric switch 5 and is arranged toward the lens 51 of the photoelectric switch 5.

[0039] Specifically, the first air duct 12 is connected to an external air source. The first end of the first air guide hole is connected to the first end of the first air duct 12 . The second end of the first air guide hole passes through the positive pressure chamber 11 and faces the lens 51 of the photoelectric switch 5 .

[0040] In one embodiment of the cleaning device of the photoelectric switch of the cigarette equipment of the present invention, four air outlets 13 are provided at the bottom of the second end of the positive pressure air chamber 11, the air outlets 13 are perpendicular to the lens 51 of the photoelectric switch 5, and the four air outlets 13 are evenly spaced along the width direction of the positive pressure air chamber 11.

[0041] Specifically, the four air outlets 13 are all connected to the first air guide hole, and the air outlets 13 are rectangular structures.

[0042] The present invention provides four air outlets 13 at the bottom of the second end of the positive pressure chamber 11. These outlets 13 are perpendicular to the lens 51 of the photoelectric switch 5. The four air outlets 13 are evenly spaced along the width of the positive pressure chamber 11 and are all connected to the first air guide hole. This allows the four air outlets 13 to clean the surface of the lens 51 of the photoelectric switch 5 in all directions, keeping the lens 51 clean. Furthermore, the rectangular shape of the air outlets 13 facilitates the formation of an air curtain of a certain thickness on the surface of the lens 51, effectively preventing dust.

[0043] In one embodiment of the cleaning device for a photoelectric switch of a cigarette making device of the present invention, the vertical cross-section of the second end of the positive pressure chamber 11 is fan-shaped.

[0044] It should be noted that since the vertical cross-section of the second end of the positive pressure chamber 11 is a fan-shaped structure, that is, the high-pressure airflow will change direction when passing through the second end of the positive pressure chamber 11 and passing through the fan-shaped surface. At this time, the pressure inside the first air guide hole will increase, and the flow rate of the high-pressure airflow discharged through the air outlet 13 will be further increased, thereby improving the effect of cleaning the dust on the surface of the lens 51 of the photoelectric switch 5 and effectively reducing the energy consumption of production.

[0045] In one embodiment of the cleaning device for a photoelectric switch of a cigarette making device of the present invention, the positive pressure purge unit 1 further includes a positive pressure air throttle valve 14, which is disposed between the positive pressure air chamber 11 and the first air duct 12. The positive pressure air throttle valve 14 is in communication with the positive pressure air chamber 11 and the first air duct 12, respectively.

[0046] It should be noted that the size of the high-pressure air flow can be adjusted according to specific needs to the positive pressure air throttle valve 14. When the lens 51 of the photoelectric switch 5 does not need to be cleaned, the positive pressure air throttle valve 14 can be directly closed.

[0047] In one embodiment of the cleaning device of the photoelectric switch of the cigarette making equipment of the present invention, as Figure 1 As shown, the negative pressure recovery part 2 includes a negative pressure air chamber 21 and a second air duct 22. A second air duct is provided inside the negative pressure air chamber 21. The second air duct 22 is connected to the second air duct. The first end of the negative pressure air chamber 21 has an air inlet, and the first end of the negative pressure air chamber 21 extends to the outside of the photoelectric switch 5 and is arranged opposite to the positive pressure purge part 1.

[0048] Specifically, the negative pressure chamber 21 and the positive pressure chamber 11 are made of aluminum alloy. The end surface of the air inlet is perpendicular to the lens 51 of the photoelectric switch 5. It should be noted that there can be one or more air inlets, without limitation. The size of the air inlet is determined based on actual needs and is not limited here.

[0049] The utility model provides a second air guide hole inside the negative pressure air chamber 21, so that the second air guide pipe 22 is connected to the second air guide hole, and an air inlet is provided at the first end of the negative pressure air chamber 21. The first end of the negative pressure air chamber 21 extends to the outside of the photoelectric switch 5, so that the air inlet and the positive pressure purge part 1 are arranged opposite to each other, so that the negative pressure air chamber 21 can recover the high-pressure airflow blown out by the positive pressure air chamber 11 and the dust cleaned by the photoelectric switch 5 through the air inlet, thereby preventing the dust from falling onto the lens 51 again and improving the dust removal efficiency.

[0050] Moreover, the lens 51 of the photoelectric switch 5 is blown by the positive pressure air chamber 11, and the negative pressure air chamber 21 sucks high-pressure airflow and dust, so that the air flow rate on the surface of the lens 51 of the photoelectric switch 5 is faster and the cleaning effect is better. The dust can be directly sucked away by the negative pressure air chamber 21 and the second air duct 22, and will not pollute other devices in the equipment.

[0051] In one embodiment of the cleaning device for a photoelectric switch in a cigarette making device of the present invention, to control the suction rate of the positive pressure chamber 11, the negative pressure recovery unit 2 further includes a negative pressure air throttle valve 23, which is disposed between the negative pressure chamber 21 and the second air duct 22. The negative pressure air throttle valve 23 is in communication with the negative pressure chamber 21 and the second air duct 22, respectively.

[0052] In one embodiment of the cleaning device of the photoelectric switch of the cigarette making equipment of the present invention, as Figure 1 As shown, the fixing assembly 3 includes a first fixing bracket 31 and a second fixing bracket 32 ​​, the first fixing bracket 31 is connected to the negative pressure recovery part 2 , the second fixing bracket 32 ​​is connected to the positive pressure purge part 1 , and the first fixing bracket 31 is connected to the second fixing bracket 32 ​​.

[0053] The utility model ensures the stability of the connection between the negative pressure recovery part 2, the positive pressure purge part 1 and the photoelectric switch 5 by connecting the first fixed bracket 31 to the negative pressure recovery part 2, the second fixed bracket 32 ​​to the positive pressure purge part 1, and the first fixed bracket 31 to the second fixed bracket 32, thereby ensuring that the negative pressure recovery part 2 and the positive pressure purge part 1 are always facing the lens 51 of the photoelectric switch 5, so as to achieve continuous and stable purge work and dust collection work.

[0054] In one embodiment of the cleaning device for a photoelectric switch of a cigarette making device of the present invention, the second fixing bracket 32 ​​has a waist-shaped hole 33 and a first mounting hole 34 , and the first fixing bracket 31 has a plurality of second mounting holes.

[0055] The fixing assembly 3 further includes a first fixing bolt 35 and a second fixing bolt 36 . The first fixing bolt 35 passes through the waist-shaped hole 33 and the second mounting hole, and the second fixing bolt 36 passes through the first mounting hole 34 and the second mounting hole.

[0056] Specifically, the plurality of second mounting holes are evenly spaced along the length direction of the first fixing bracket 31 , and the sizes of the second mounting holes correspond to the sizes of the waist-shaped hole 33 and the first mounting hole 34 .

[0057] The utility model provides a waist-shaped hole 33 and a first mounting hole 34 on the second fixing bracket 32, and provides multiple second mounting holes on the first fixing bracket 31, so that the first fixing bolt 35 passes through the waist-shaped hole 33 and the second mounting hole, and the second fixing bolt 36 passes through the first mounting hole 34 and the second mounting hole, thereby ensuring the stability of the connection between the first fixing bracket 31 and the second fixing bracket 32; and, through the provision of the waist-shaped hole 33 and the multiple second mounting holes, the distance between the first fixing bracket 31 and the second fixing bracket 32 ​​can be adjusted, so as to adapt to photoelectric switches 5 of different heights, thereby effectively improving the practicality of the cleaning device of the photoelectric switch of the cigarette equipment of the utility model.

[0058] In one embodiment of the cleaning device of the photoelectric switch of the cigarette making equipment of the present invention, as Figure 2 As shown, the dust collection assembly 4 includes a dust collection box 41 and a filter plate 42. The bottom of the dust collection box 41 has multiple exhaust ports 43. The top of the dust collection box 41 is connected to the negative pressure recovery part 2. The filter plate 42 is arranged inside the dust collection box 41.

[0059] Specifically, the filter plate 42 has a plurality of filter holes for filtering dust in the airflow, and there can be multiple filter plates 42, which is not limited.

[0060] An opening 44 is provided on the side wall of the dust collecting box 41, and the filter plate 42 is inserted into the interior of the dust collecting box 41 through the opening 44. The operator pulls the filter plate 42 out of the dust collecting box 41, thereby being able to clean the dust on the filter plate 42.

[0061] The utility model has multiple exhaust ports 43 at the bottom of the dust collection box 41, and the top of the dust collection box 41 is connected to the negative pressure recovery part 2.
