[0002] In the tobacco packaging industry, a cigarette tipping paper slitter is an indispensable device in the production process, which is used to cut large rolls of tipping paper into narrow coils or sheets suitable for packaging. Traditional waste edge collection devices usually adopt manual cleaning or simple mechanical dust suction systems. Among them, manual cleaning relies on operators to manually collect waste edges, with low efficiency; mechanical dust suction systems mostly adopt fixed suction port designs, and suck waste edges into a dust collection box or waste bin through negative pressure. These devices meet the basic collection requirements to a certain extent and have been widely used in tobacco packaging production lines.

Waste edges are usually mixed and collected into a single container, resulting in more complex subsequent processing and increasing the difficulty of recycling or treatment. Especially when large waste edges and small waste edges are mixed, it may cause blockage of the dust collection box or a decrease in processing efficiency due to volume differences.

[0052] Please refer to the appendix Figure 8 , a method for automatically collecting waste edges of cigarette tipping paper cutting machines, characterized in that it is used for the automatic waste edge collection device of the cigarette tipping paper cutting machine according to any one of claims 1-9, and includes the following steps:

[0053] S1. Turn on the motor 4 to drive the negative pressure fan 5 to generate negative pressure, collect waste edges through the first suction pipe 7, the pipe shell 8 and the second suction pipe 9, and the robotic arm 16 intelligently adjusts the position of the second suction pipe 9;

[0054] S2. The waste edges are diverted through the pipe shell 8, the larger waste edges fall into the first waste material tank 14, the smaller waste edges fall into the second waste material tank 15, and the fine dust enters the dust collection box 6;

[0055] S3. After the waste material tank is full, step on the foot pedal 17 to release the pressing plate 24 and take out the waste material tank to process the waste edges.

[0056] Specifically, in S1, first turn on the motor 4, and the motor 4 will drive the negative pressure fan 5 to rotate to generate negative pressure, adsorb and collect the waste edges of the cigarette tipping paper through the first suction pipe 7, the pipe shell 8 and the second suction pipe 9, and then automatically identify the position of the waste edges through the robotic arm 16 to adjust the second suction pipe 9 for automatic collection;

[0057] The waste edges collected through the second suction pipe 9 will pass through the pipe shell 8. When the waste edges pass through the pipe shell 8, the larger waste edges will be intercepted by the baffle 10 and fall into the interior of the first hollow shell 12, and then fall into the interior of the first waste material tank 14 through the first hollow shell 12 for collection. The smaller waste edges will pass through the middle of the baffle 10 to reach the surface of the guide shaft 11. There are inclined downward hypotenuses around the guide shaft 11, which will guide the smaller waste edges downward into the interior of the second hollow shell 13. The smaller waste edges will then fall into the interior of the second waste material tank 15 through the second hollow shell 13 for collection. Finally, the fine dust and the like will pass through the first suction pipe 7 and the interior of the fan housing 3 and be discharged by the negative pressure fan 5 into the interior of the dust collection box 6 for collection;

[0058] S3. When the waste edges in the first waste bin 14 and the second waste bin 15 are fully collected, step on the foot pedal 17. One end of the foot pedal 17 will slide downward inside the bottom side of the bracket 1. When the foot pedal 17 slides downward, it will drive the sliding shell 18 to move downward. When the sliding shell 18 moves downward, it will cause the connecting shaft 19 to rotate and slide inside the sliding shell 18. When the connecting shaft 19 rotates, it will drive the connecting shell 20 to rotate downward. When the connecting shell 20 rotates downward, it will drive the rotating shaft 21 to rotate in place. When the rotating shaft 21 rotates, it will drive the extrusion block 22 to rotate. When the extrusion block 22 rotates, the extrusion plate 24 will no longer press upward on the first waste bin 14 and the second waste bin 15. Finally, pull out the first waste bin 14 and the second waste bin 15 for disassembly and process the waste edges inside them.

[0059] The following is an introduction in combination with the specific work process:

[0060] Waste edge collection and intelligent adjustment: The motor 4 starts, with a power of 1.5 kW and a rotation speed of 3000 rpm, driving the negative pressure fan 5 to rotate, generating a negative pressure of 500 Pa and an air volume of 2000 m³ / h. The negative pressure forms suction through the first suction pipe 7, the pipe shell 8 and the second suction pipe 9, covering a working area of 500 mm of the slitter, and sucking 0.5 kg of waste edges each time. The infrared sensor on the robotic arm 16 scans at a frequency of 1 Hz, detecting distances from 10 - 200 cm with an accuracy of ±5 mm, generating the coordinates of the waste edges. The microcontroller runs the PID algorithm, with an operation time of 50 ms, calculating the movement path of the robotic arm 16, with an error < 2 mm. The servo motor adjusts the angle, with a speed of 30 degrees per second, a range of ±60 degrees, and a response time of 0.3 seconds, ensuring that the second suction pipe 9 is aligned with the waste edges. If the waste edges are unevenly distributed, the system preferentially adjusts to the high-density area, with an efficiency increase of 20%. In case of an abnormality (such as a signal interruption), the alarm is triggered, with a sound of 80 decibels, prompting an inspection.

[0061] Waste edge diversion and classified collection: After the waste edges enter the pipe shell 8, the baffle 10 intercepts larger waste edges (>10 mm), with an interception efficiency of 90%, an angle adjustment range of 0 - 45 degrees, an accuracy of ±1 degree, and a sliding speed of 0.3 m / s, falling into the first hollow shell 12. The anti-sticking coating on the inner wall reduces adhesion, and it falls into the first waste bin 14 in 1 second, with a capacity of 50 L, which can store 5 kg of waste edges. Smaller waste edges (<10 mm) pass through the through holes, with an air flow speed of 5 m / s, sliding down along the hypotenuse of the guide shaft 11. The hypotenuse angle is 30 degrees, the friction coefficient is 0.1, and the sliding speed is 0.2 m / s, falling into the second hollow shell 13 and entering the second waste bin 15, with a capacity of 30 L, which can store 3 kg of waste edges. The fine dust enters the dust collection box 6 along with the air flow, with an air flow speed of 5 m / s, intercepted by three layers of filter screens. The first layer has a pore size of 1 mm, the second layer is 0.5 μm, and the third layer of HEPA filter screen has an accuracy of 0.3 μm, with an interception efficiency of 99.97% to ensure hygiene.

[0062] Scrap Edge Compression and Treatment: After the scrap bin is full, the operator confirms through the observation window, steps on the foot pedal 17 with an operating force of 80 N and moves down 30 degrees, driving the sliding shell 18 to move down 50 mm with a resistance of 10 N. The connecting shaft 19 rotates 45 degrees, driving the connecting shell 20 and the rotating shaft 21 to move. The rotating speed of the rotating shaft is 10 rpm, and the extrusion block 22 rotates 90 degrees to release the pressure on the extrusion plate 24. The resistance of the scrap bin slide rail is 20 N, the removal time is 20 seconds, and the scrap edge is sent to the recycling station for treatment. After the scrap bin is reinstalled, the foot pedal 17 resets with a spring force of 50 N to complete the cycle.
