Description

Technical Field

[0001] This invention belongs to the field of tobacco recycling technology, specifically relating to a tobacco recycling device and control method. Background Technology

[0002] In the cigarette manufacturing process, the centralized dust removal process is a key technology for tobacco shreds and dust recovery. The negative pressure pipeline connects each machine, and while meeting the requirements of the cigarette manufacturing process, it recovers some tobacco shreds and dust to the centralized dust removal system. The dust is recovered through the centralized dust removal pipeline and then conveyed to the press briquette machine hopper by a screw conveyor for pressing. At the same time, tobacco shreds and tobacco stems are screened by stem skewer air conveying and stem skewer air separation.

[0003] The dust collection and recovery pipeline consists of: process air supply, process tobacco feeding, negative pressure cleaning, stem and stalk conveying, and screw conveyor. When the cigarette rolling unit receives a start-up signal, the centralized dust collection system starts first, followed by the automatic activation of the screw conveyor and briquette press, and then the process air supply and process tobacco feeding systems. Generally, the centralized dust collection system uses a 15kW fan, while the process air supply uses a 132kW fan and the process tobacco feeding uses a 60kW fan. The required process airflow for both is approximately 12,000 and 10,000 cubic meters per second, respectively, and their frequency is adjusted according to the number of machines in operation. Due to the relatively high negative pressure, a large amount of tobacco shreds is present in the smoke during centralized dust collection and recovery. Adjusting the negative pressure to reduce the tobacco shred content cannot guarantee the control process requirements. According to cigarette recycling requirements, tobacco shreds larger than or equal to 5mm can be recycled.

[0004] Therefore, a tobacco shred recycling device and control method are needed to improve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a tobacco shred recycling device and control method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0058] Example 1: Basic working process of the tobacco shred recycling device:

[0059] Equipment installation and commissioning;

[0060] Place the tobacco recycling device on a level, stable work platform, ensuring that the four support legs of the mounting bracket 7 are in full contact with the ground to prevent displacement during vibration.

[0061] Check that all fasteners, such as bolts and metal clamps, are secure, and ensure that components such as the vibration motor 1, hydraulic cylinder 20, and servo motor are installed reliably.

[0062] Connect the power supply, start the vibration motor 1, observe whether the vibration amplitude of the screening cylinder 4 is uniform, and adjust the frequency of the vibration motor 1 to 1500 r / min to ensure the efficiency of tobacco shredding.

[0063] Tobacco shredding process;

[0064] Open the cover plate 12 and pour the tobacco to be recycled evenly into the annular enclosure 10 through the feed inlet 13.

[0065] Vibration motor 1 drives screening cylinder 4 to vibrate at high frequency through support spring 5. Fine tobacco shreds ≤5mm fall through screening screen 14 into collection funnel 8 below and are discharged from the bottom; longer tobacco shreds >5mm move along the inclined screening screen 14 under vibration and are finally discharged from discharge port 3.

[0066] The screening process lasts for 3-5 minutes until there are no residual tobacco shreds within the ring-shaped enclosure 10.

[0067] Automatic screen cleaning;

[0068] Turn off the vibration motor 1, start the hydraulic cylinder 20, and push the mesh cover plate 17 down to the cleaning position with a descent stroke of about 50mm, so that the lower surface of the mesh cover plate 17 is in contact with the rubber friction wheel 16.

[0069] Activate cleanup mechanism 29:

[0070] Stepper motor 22 drives rotary table 23 to rotate 90°, positioning hollow rotating shaft 25 in the center area of ​​screen 14.

[0071] The second servo motor 24 starts, driving the hollow shaft 25 to rotate at 200 r / min, and the brush 26 brushes the surface of the screen 14.

[0072] Simultaneously start the air pump 21, and compressed air at 0.3MPa enters the sealed cavity 28 through the hose and is sprayed through the jet hole 27 of the hollow rotating shaft 25 to help clear stubborn blockages.

[0073] Start the first servo motor 15 to drive the rubber friction wheel 16 to rotate slowly at 30 r / min, which in turn drives the screen plate 17 to rotate as a whole, ensuring that the brush 26 covers the entire screen area.

[0074] The cleaning process takes about 5 minutes. After completion, the air pump 21, servo motor and stepper motor are turned off in sequence.

[0075] Reset and maintenance;

[0076] The hydraulic cylinder 20 retracts, raising the mesh cover 17 to its initial position.

[0077] By removing the fixing bolts of the cleaning mechanism 29, the brush 26 or the hollow rotating shaft 25 can be replaced or cleaned.

[0078] Working principle:

[0079] Start the vibration motor: Place the tobacco recycling device on a flat and stable working platform to ensure the stability of the mounting frame 7, connect the power supply, and start the vibration motor 1. The vibration motor 1 drives the screening cylinder 4 to vibrate through the support spring 5.

[0080] Tobacco shred recycling: The tobacco shreds to be recycled are poured into the annular enclosure 10 through the feed inlet 13. Under the action of the vibrating motor 1, the screening cylinder 4 shakes, and the fine tobacco shreds are screened through the screening screen 14, falling into the collection funnel 8 at the bottom and being discharged from the bottom. The longer tobacco shreds of better quality are discharged from the discharge port 3 on the side of the annular enclosure 10. After all the tobacco shreds in the annular enclosure 10 have been screened, the vibrating motor 1 is turned off to complete the tobacco shred recycling operation.

[0081] Screen cleaning operation:

[0082] The screen plate descends: the hydraulic cylinder 20 is activated, and the hydraulic cylinder 20 drives the screen plate 17 to descend, so that the screening screen 14 descends to the bottom of the inner side of the screening cylinder 4. At the same time, the lower surface of the screen plate 17 is in contact with the rubber friction wheel 16.

[0083] Start cleaning mechanism 29: Stepper motor 22 drives rotating table 23 to rotate, rotating hollow rotating shaft 25 from the inner edge of screening cylinder 4 to above screening screen 14;

[0084] Start the second servo motor 24, which drives the hollow shaft 25 to rotate. The brush 26 on the surface of the hollow shaft 25 rotates and cleans the surface of the screen 14.

[0085] At the same time, the air pump 21 is started. The air pump 21 fills the sealed cavity 28 with air through the hose. The gas enters the hollow rotating shaft 25 and is sprayed out from the air jet hole 27 on the surface of the hollow rotating shaft 25 to clear the blockage of the screen 14.

[0086] All-round cleaning: Start the first servo motor 15, which drives the rubber friction wheel 16 to rotate. The rubber friction wheel 16 is connected to the lower surface of the screen plate 17, which drives the screen plate 17 to rotate at one end of the hydraulic cylinder 20 through the bearing, thereby achieving all-round cleaning of the screening screen 14.
