[0059] The calculation method of the process is as follows: one baffle cabinet is 22 meters, the baffle cabinet is divided into 100 grids, each grid is 22 cm, and the discharge bottom belt is counted once per grid. Each pulse of the proximity switch 20 represents a grid distance, and a count of 10 is 10% of the discharge. The current value of the count can be used to calculate the process.

[0060] The head and tail are set according to the actual situation, for example, when the discharge process of each cabinet is less than 5%, it is the head, and when it is greater than 95%, it is the tail. Since the material layer in the head and tail baffle cabinet is thin, the speed needs to be adjusted, the fast discharge mode needs to be used to prevent the supply of material, the speed of the baffle cabinet bottom belt 19 needs to be increased to realize the stable switching of the material.

[0061] The bin feeder includes a baffle bin 21, a lifting belt 22, and an electronic belt scale 23. The baffle bin 21 is used for temporarily storing the material input into the bin feeder. A high material level photoelectric tube 24 and a low material level photoelectric tube 25 are arranged at the inlet end of the baffle bin 21, and a discharge photoelectric tube 26 is arranged at the outlet end of the baffle bin 21. The high material level photoelectric tube 24 and the low material level photoelectric tube 25 are used to detect the amount of material in the baffle bin 21 in real time. When all the photoelectric tubes of the bin feeder do not have signals, i.e., there is no material in the bin feeder, the controller delays to stop the operation of the bin feeder.

[0062] The discharge photoelectric tube 26 is used to detect the discharge of the baffle bin 21 in real time, and the starting of the lifting belt 22 and the operation of the baffle bin bottom belt 31 are controlled according to the signal of the discharge photoelectric tube 26. The outlet end of the baffle bin 21 is connected with the inlet end of the lifting belt 22, the outlet end of the lifting belt 22 is connected with the electronic belt scale 23 through a metering pipe 30, and three metering photoelectric tubes are arranged at the outlet end of the lifting belt 22 to measure the material in the metering pipe 30. The photoelectric tubes are all using the opposite type photoelectric tube, which outputs a signal when there is material in the middle of the photoelectric tube.

[0063] The output end of the electronic belt scale 23 is connected with the baffle dryer, and the electronic belt scale 23 is used to control the material flow. By adjusting the speed of the electronic belt scale 23, the instantaneous flow of the tobacco stem is controlled. The bin feeder controls the tobacco stem flow to be stable through the electronic belt scale 23, so as to meet the requirements of the temperature and moisture control of the tobacco stem in the subsequent baffle dryer.

[0064] The controller is used to receive and control various modules in the system. The controller is connected with the switching transport belt 3, the first bin feeder 4, the second bin feeder 6, the first baffle cabinet output transport belt 11, the second baffle cabinet output transport belt 12, the first feeding transport belt 13, the third baffle cabinet output transport belt 16, the fourth baffle cabinet output transport belt 17, the second feeding transport belt 18, the baffle cabinet bottom belt 19, the proximity switch 20, the lifting belt 22, the electronic belt scale 23, the high material level photoelectric tube 24, the low material level photoelectric tube 25, the discharge photoelectric tube 26, the low position metering photoelectric tube 27, the middle position metering photoelectric tube 28, and the high position metering photoelectric tube 29.

[0065] When the system is started, the controller will start the corresponding transport belts (except for the switching transport belt 3), and at the same time, it will detect the material transportation status of the two production lines in real time. When the two bale cabinets of the same production line are discharging at the same time, the bale cabinet bottom belt 19 runs at low speed. When one cabinet is discharging, the bale cabinet bottom belt 19 runs at high speed. When the two bale cabinets are switched, the speed remains basically unchanged. After switching, the discharge progress in the bale cabinet is obtained through the proximity switch 20, and the discharge bottom belt speed is automatically adjusted. When the baling machine or the subsequent process of one of the production lines fails, resulting in shutdown or the current material needs to be combined, the controller starts the switching transport belt 3. For example, the material needs to be uniformly conveyed to the first baling machine 5 for processing. At this time, the switching transport belt 3 outputs from right to left, and the output end is connected with the first feeding transport belt 13. At this time, the materials in the third bale cabinet 14 and the fourth bale cabinet 15 are conveyed to the first feeding transport belt 13 through the third bale cabinet output transport belt 16, the fourth bale cabinet output transport belt 17, the switching transport belt 3, and then input to the first baling machine 5. The second feeding transport belt 18, the second baling machine 7, and the second bin feeder 6 of the second production line 2 are disabled.

[0066] During operation, when the high-level photoelectric tube 24 of the first bin feeder 4 is blocked, the high-level photoelectric tube 24 generates a signal and outputs it to the controller. At this time, the bale bin 21 is full of material, and the controller controls the bale cabinet bottom belt 19 to reduce by 2 (set according to actual needs) hertz every 2 seconds until the high-level signal disappears. At the same time, the timer is started, and if the blocking time reaches the delay, the bale discharge is stopped, and the photoelectric tube is checked for whether there is material blocking affecting the measurement.

[0067] When the low-level photoelectric tube 25 of the bale bin 21 has no signal, the material in the bale bin 21 is insufficient. At this time, the bale cabinet bottom belt 19 starts to supply material to the bale bin of the first bin feeder 4 through the first feeding transport belt 13. As long as the low-level signal does not exist, the first feeding transport belt 13 and the bale cabinet bottom belt 19 continue to run. When the low-level photoelectric tube 25 of the bale bin 21 has a signal, the bale bin bottom belt 31 starts to run and sends the material in the bin to the lifting belt 22. When the discharge photoelectric tube 26 has a signal, the lifting belt 22 starts to run, and the bale bin bottom belt 31 runs intermittently to prevent material breakage. Until the delay stops.

[0068] When a signal is received at the discharge end, the lifting belt 22 starts, outputting the material in the stem bin 21 to the electronic belt scale 23. Three measuring photocells are installed at the discharge end of the lifting belt 22: a low-level measuring photocell 27, a middle-level measuring photocell 28, and a high-level measuring photocell 29. These photocells measure the material in the measuring tube 30 and control the speed of the lifting belt 22 based on the material level. Material at the output end of the lifting belt 22 causes signals from the low-level and middle-level measuring photocells 27 and 28. When the high-level measuring photocell 29 does not generate a signal, the system operates normally. At this time, the material flow rate keeps the material at the middle level, thus maintaining the electronic belt scale 23 stable and meeting the requirements of the subsequent stem roasting machine processing. When the high-level measuring photocell 29 generates a signal, it indicates excessive material output, and the controller slows down or stops the lifting belt 22.

[0069] When two production lines are running simultaneously, if the material on the electronic belt scale 23 is consistently too low, and the controller cannot meet the material output requirements after adjusting the front output belt, the operator can manually select the controller to switch the conveyor belt 3 and shut down one of the production lines, thus merging the two production lines.

[0070] like Figure 4 The system flowchart shown illustrates three transportation modes in system operation:

[0071] Mode 1:

[0072] Production line 1 operates as a single line, while production line 2 is merged into production line 1 for processing. At this time, switching conveyor belt 3, first discharge conveyor belt 32, and second discharge conveyor belt 33 operate in the same direction as the first feeding conveyor belt 13. Materials in hopper 8 and hopper 9 are respectively discharged via hopper 1 output conveyor belt 11 and hopper 2 output conveyor belt 12 to the first discharge conveyor belt 32, and then via the first feeding conveyor belt 13 to the first bin-type feeder 4. Materials in hopper 14 and hopper 15 are respectively discharged via hopper 3 output conveyor belt 16 and hopper 4 output conveyor belt 17 to the second discharge conveyor belt 33, and then via the second discharge conveyor belt 33, switching conveyor belt 3, first discharge conveyor belt 32, and first feeding conveyor belt 13 to the first bin-type feeder 4.

[0073] Mode 2:

At this time, the switching conveyor belt 3, the first discharge conveyor belt 32, the second discharge conveyor belt 33 and the second feeding conveyor belt 18 are operated in the same direction. The materials in the third stem cabinet 14 and the fourth stem cabinet 15 are output to the second discharge conveyor belt 33 through the third stem cabinet output conveyor belt 16 and the fourth stem cabinet output conveyor belt 17 respectively, and then output to the second warehouse feeder 6 through the second feeding conveyor belt 18. At this time, the materials in the first stem cabinet 8 and the second stem cabinet 9 are output to the first discharge conveyor belt 32 through the first stem cabinet output conveyor belt 11 and the second stem cabinet output conveyor belt 12 respectively, and then output to the second warehouse feeder 6 through the first discharge conveyor belt 32, the switching conveyor belt 3, the second discharge conveyor belt 33 and the second feeding conveyor belt 18.

[0075] Mode three:

[0076] The first production line 1 and the second production line 2 are operated in single line, at this time, the two lines are operated simultaneously, the switching conveyor belt 3 is stopped, the first discharge conveyor belt 32 is operated in the same direction with the first feeding conveyor belt 13, and the second discharge conveyor belt 33 is operated in the same direction with the second feeding conveyor belt 18.
