[0002] The cigarette production industry is an industry under special state management. Only approved enterprises can carry out production. At the same time, the state has strict regulations on the handling of raw materials, waste materials, and substandard products in the cigarette production process. For example, the National Tobacco Law
[2006] No. 375 stipulates that "the defective, discarded tobacco leaves and tobacco dust that can be recycled and reused in the production and operation process of enterprises can only be sold to relevant production enterprises such as recycled tobacco leaves and tobacco flakes in the industry; those that cannot be recycled must be destroyed"; it also stipulates that "it is necessary to strengthen the supervision and management of defective, discarded tobacco leaves, tobacco dust, cigarette paper, filter rods, and tobacco silk bundles, formulate a management system with clear rights and responsibilities, and assign responsibilities to individuals. The illegal purchase, operation, and transportation of defective, discarded tobacco leaves, tobacco dust, cigarette paper, filter rods, and tobacco silk bundles must be severely investigated and dealt with in accordance with the law."
[0003] During the production process of cigarettes, a conveyor belt is needed to transport tobacco raw materials. Tobacco leaves contain fine tobacco dust, some of which will adhere to the surface of the conveyor belt during transportation. When the conveyor belt returns, the tobacco dust will fall due to the influence of gravity, vibration and other factors. In order to prevent the fallen tobacco dust from covering the ground, a supporting component is set under the conveyor belt to receive the fallen tobacco dust. When the amount of tobacco dust received on the surface of the supporting component reaches a certain level, it needs to be manually cleaned and collected. At present, in the above-mentioned operation process, most of the collection and measurement of tobacco dust after cleaning is completed by manual work, which not only has a large workload and high work intensity, but also is difficult to implement tobacco dust measurement, resulting in a lack of accuracy in the measurement value of tobacco dust, and it is impossible to further manage tobacco dust waste.

[0013] The present invention also provides a method for collecting cigarette dust, which is applied to the above-mentioned cigarette dust collection system, and the specific steps include: Step S1: Start the system and set the parameters Turn on the power supply, close the air switch to power on the controller, and then power on the reset button, display, data transmitter, indicator light and laser distance sensor. Power on and start the host computer and power on the data receiver at the same time. Then, set the current date through the display and set the limit value of the data monitored by the laser distance sensor. The limit value corresponds to the maximum height of the cigarette dust accumulation in the storage bin. The maximum height of the cigarette dust in the storage bin is not higher than the total height of the lower part of the storage bin. Finally, run the system; Step S2: Collecting jobs First, the belt pallet is cleaned manually, and the accumulated cigarette dust on the surface of the belt pallet is cleaned from the head end of the belt pallet to the tail end of the belt pallet, so as to be further sent to the inside of the storage bin, so that the cigarette dust falls and gradually accumulates at the bottom of the storage bin.

When the active bin cleaning preparation method is adopted, it is necessary to manually check the accumulation height of the smoke dust inside the storage bin monitored by the laser distance sensor at this time displayed on the display interface, and then further observe the smoke dust collection situation inside the storage bin through the observation window. Finally, the operator pulls the hammer outward for a distance, releases the hammer, and causes the hammer to hit the reinforcing ring to vibrate the smoke dust attached to the inner wall of the storage bin to the bottom of the storage bin under the action of the hammer vibration, so that the laser distance sensor can monitor the actual accumulation height of the smoke dust in the storage bin at this moment and transmit the data information to The controller is used to complete active warehouse clearing preparations; it also includes passive warehouse clearing preparations. When the laser distance measuring sensor detects that the accumulation height of the cigarette dust in the storage bin has reached the set limit value, the controller controls the indicator light to light up to remind the operator to clear the cigarette dust in the storage bin. Then, the operator pulls the hammer outward for a distance, releases the hammer, and causes the hammer to hit the reinforcing ring to vibrate the cigarette dust attached to the inner wall of the storage bin to the bottom of the storage bin under the action of the hammer vibration, so that the laser distance measuring sensor can monitor the actual accumulation height of the cigarette dust in the storage bin at this moment and transmit the data information to the controller to complete the passive warehouse clearing preparations. Step S4: Data calculation, transmission and reset After the warehouse cleaning preparation work is completed, the operator immediately presses the reset button and uses the controller to simply calculate the actual accumulated volume of cigarette butts in the storage bin. The calculation formula for the actual accumulated volume V of cigarette butts is: V = k × S × h, Where: S is the cross-sectional area of the bottom of the storage bin; h is the accumulation height of the smoke dust in the storage bin monitored by the laser ranging sensor; k is the correction coefficient; Subsequently, the controller records and transmits the corresponding serial number information of the smoke dust collection system, the current time and date, and the actual smoke dust accumulation volume data obtained through calculation to the data receiver through the data transmitter, and at the same time, the accumulated height data of the smoke dust in the storage bin obtained through monitoring and the actual smoke dust accumulation volume data obtained through simple calculation are cleared to facilitate the next round of real-time monitoring process; finally, the data receiver transmits the remotely received information to the host computer for aggregation, measurement and statistics to further form visual data information; Step S5: Clearing the warehouse and shutting down the system Open the cleaning door, clean out all the tobacco powder in the storage bin through the cleaning port and transport them to the designated area, and close the cleaning door; determine whether to stop the system according to actual production needs. If it needs to be stopped, open the control cabinet and push the air switch to cut off the power to the controller and stop running. If it does not need to be stopped, return to step S2 to continue the next round of real-time monitoring and clearing operations.

[0018] In the embodiment described in the present invention, the belt conveyor 4 has the function of transporting tobacco leaves, and the belt pallet 2 can receive the tobacco dust adhered to the belt surface of the belt conveyor 4 and dropped during rotation during the tobacco leaf transportation process. The belt pallet 2 is arranged below the belt conveyor 4 in a form parallel to the inclination of the belt conveyor 4. The tobacco dust falling on the surface of the belt pallet 2 can be collected in a recovery device along the extension trend of the belt pallet 2 after manual cleaning.
[0019] In the embodiment of the present invention, the storage bin 17 can collect the cigarette dust swept from the belt support plate 2 for centralized cleaning. The top edge of the storage bin 17 is connected to the belt support plate 2 so that the cigarette dust swept from the surface of the belt support plate 2 can smoothly enter the storage bin 17. The material used for the storage bin 17 is galvanized iron plate. The upper part of the storage bin 17 is set as a funnel-shaped structure, and the lower part of the storage bin 17 is set as a quadrangular prism-shaped structure.

The percussion hammer 21 hits the reinforcement ring 22, so that the cigarette dust attached to the inner wall of the storage bin 17 is vibrated to the bottom of the storage bin 17 under the action of hammer vibration. At the same time, the cigarette dust pile accumulated at the bottom of the storage bin 17 has a higher flatness, which is convenient for accurately determining the actual collection amount of cigarette dust in the storage bin 17. The setting height of the percussion hammer 21 is the same as the setting height of the reinforcement ring 22. The percussion hammer 21 is fixed to the middle section of the elastic band 23 by a top screw 25. The percussion hammer 21 is made of nylon, and the upper and lower ends of the elastic band 23 are fixed to the storage bin 17 by bolts.
