Description

Technical Field

[0001] The invention relates to the technical field of tobacco feeding rollers, in particular to an automatic cleaning device for a tobacco feeding roller. Background Art

[0002] The feeding roller equipment is an indispensable equipment in the tobacco silk making process. After the tobacco is treated by the roller, the moisture content and temperature of the tobacco can be quickly increased, which directly affects the quality of cigarettes. The roller has a direct impact on improving the quality of cigarette products, giving full play to the potential of tobacco raw materials, improving tobacco defects and improving the effective utilization rate of liquid materials. Therefore, the use of the feeding roller has greatly improved the work efficiency of tobacco silk making. However, during the feeding and rehumidification process, some residual tobacco dust usually accumulates in the roller. These debris can easily form lumps and mix in the tobacco. In the long run, it will cause tobacco of different brands to be mixed, thus affecting the quality of the production process.

[0003] During the tobacco production process, tobacco leaves sticking to the inner wall of the drum is an unavoidable production problem in domestic cigarette factories. The production brand is often changed during tobacco processing, that is, the same drum equipment is often used to produce tobacco products of different qualities. This requires that when changing the production brand of tobacco leaves, the drum equipment needs to be cleaned to avoid mixing of tobacco leaves of different qualities. Traditional equipment does not have an automatic cleaning function, and it is often necessary to manually enter the interior of the drum for flushing and cleaning after the drum is stopped. This poses a safety hazard to the cleaning staff, and the cleaning efficiency is low. Therefore, how to design an automatic cleaning device for the tobacco feeding drum to improve the cleaning efficiency of the drum and reduce labor costs and safety hazards is a difficulty that technical personnel in this field need to solve. Therefore, the present invention is specially proposed. Summary of the Invention

[0036] In the embodiment of the case, the driving mechanism 7 includes an outer frame 701, a servo motor 702 and a clamping roller shaft 703. The outer frame 701 is provided on the top right side of the bottom plate 601. The servo motor 702 is provided on the top of the outer frame 701. Two clamping roller shafts 703 connected to the servo motor 702 are provided on the inner side of the outer frame 701.

[0037] Specifically, a through hole is provided on the outer frame 701, and the connecting tube 804 passes through the through hole and is tangent to the two clamping roller shafts 703. When the driving mechanism 7 is driven by the servo motor 702, the two clamping roller shafts 703 inside the driving mechanism 7 will rotate, driving the connecting tube 804 to move.

The gas storage tank 11 is provided with a temperature detector 12 and a pressure detector 14;

[0043] Specifically, the compressed gas processing device 2 can be started and stopped by the DCS control system 1. During the feeding process, the steam required for steam injection can be stored in the gas storage tank 11 through the DCS control system 1. After the feeding is completed and the cleaning stage begins, steam can be directly called from the gas storage tank 11 for cleaning, which effectively reduces the cleaning time.

The gas and liquid from the compressed gas treatment device 2 and the tap water treatment device 3 will be transported to the high-pressure blowing mechanism 8 through the gas pipe 802 and the water pipe 803.

[0046] In the case implementation, DCS control system 1 consists of Honeywell's PKS system, touch screen, low-voltage electrical appliances, relays, and switches. It supports the PKS system, FTE fault-tolerant Ethernet, C300 controller, various I / O cards, RS485 and RS232 bus interfaces, and has data transmission and remote control functions.

[0047] The DCS control system 1 is set in an independently installed electric control box and is used to set, control, move and display the parameters of the automatic cleaning device to complete an automatic cleaning process.

[0048] In the case implementation, the automatic cleaning device can adjust the working mode according to the working conditions, specifically:

[0049] 1. Blowing stage: The high-pressure blowing mechanism 8 is connected to the compressed gas processing device 2 and controlled by the corresponding control circuit in the DCS control system 1. In the pre-set blowing mode, the first solenoid valve 13 is opened to introduce the compressed gas pre-stored in the gas tank 11. The servo motor 702 is operated, which drives the drive mechanism 7 to operate, driving the connecting pipe 804 to operate, so that the nozzle 805 enters one end of the drum to start blowing. When the drum reaches the other end, the drive mechanism 7 drives the connecting pipe 804 to retreat. When it reaches the drum outlet, the blowing ends.

[0050] 2. Cleaning stage: The high-pressure spraying mechanism 8 is connected to the tap water treatment device 3 and controlled by the corresponding control circuit in the DCS control system 1. In the pre-set cleaning mode, the second electromagnetic valve 18 is turned on to introduce tap water pre-stored in the water storage pump 16, drive the servo motor 702, and operate the driving mechanism 7, which drives the connecting pipe 804 to operate, so that the nozzle 805 enters one end of the drum and starts to spray. When the drum reaches the other end, the driving mechanism 7 drives the connecting pipe 804 to retreat. When it reaches the drum outlet, the spraying ends.

[0051] 3. Evaporation stage: The high-pressure blowing mechanism 8 is connected to the compressed gas processing device 2 and is controlled by the corresponding control circuit in the DCS control system 1. During the cleaning stage, the steam can be stored in the gas storage 11. After the cleaning stage is completed, the first solenoid valve 13 is opened in the pre-set blowing mode to introduce the compressed gas pre-stored in the gas storage tank 11, drive the servo motor 702, and operate the driving mechanism 7, which drives the connecting pipe 804 to operate, so that the nozzle 805 enters one end of the drum and starts to blow. When the drum reaches the other end, the driving mechanism 7 drives the connecting pipe 804 to retreat. When it reaches the drum outlet, the blowing ends.

[0052] To sum up, the automatic cleaning device of the tobacco feeding drum can adjust the cleaning component 4 to a suitable position when the drum needs to be cleaned, and use the remote control function to drive the compressed gas treatment device 2, the tap water treatment device 3, and the driving mechanism 7 on the frame 6. At this time, the connecting pipe 804 will be driven by the driving mechanism 7 to slide forward slowly, and the high-pressure blowing mechanism 8 will supply gas or liquid into the connecting pipe 804, and the nozzle 805 will spray gas or liquid into the inner wall of the drum to clean the drum. The start and stop of the spraying, delay time, and the associated intervals can all be set and operated through the human-machine interface, and can also be managed and monitored in real time. Workers do not need to frequently enter the drum, which greatly reduces the occurrence of safety accidents and effectively improves the efficiency of the plot.

[0053] In addition, by setting up a DCS control system 1 and utilizing the remote control function, the compressed gas processing device 2, the tap water processing device 3, and the driving mechanism 7 on the frame 6 can be driven. The start and stop of the spraying, the delay time, the associated interval, etc. can all be set and operated through the human-machine interface. Real-time management and monitoring can also be performed, which greatly reduces labor costs. The connecting pipe 804 and the two clamping roller shafts 703 will be made of rubber, which greatly improves the service life of the equipment. The nozzle 805 can achieve 360° cleaning of the drum and cover the entire three-dimensional space of the drum. The nozzle 805 can clean the inside of the drum twice when moving forward and backward, which greatly improves the cleaning efficiency, is easy to load and unload, and is also very convenient for cleaning this equipment.
