[0029] See also Figures 1 to 6 A tobacco leaf shredded discharging control system comprises: a feed box 100, a shredding box 200 and a control module. A sorting and conveying assembly 110 is arranged inside the feed box 100. The sorting and conveying assembly 110 is used to sort and spread out the transversely stacked tobacco leaves and convey them to the next station; the shredding box 200 is arranged below the feed box 100. A shredding assembly 210, a cleaning assembly 220 and a discharging assembly are arranged inside the shredding box 200 from top to bottom. The shredding assembly 210 is used to sort and convey the sorting and conveying assembly The tobacco leaves transported by 110 are shredded, the cleaning component 220 is used to clean the tobacco shreds remaining after the tobacco leaves are shredded, and the discharging component is used to output the shredded tobacco; the control module is electrically connected to the sorting and conveying component 110, the shredding component 210 and the cleaning component 220, and the control module is electrically connected to the weighing module, which is used to weigh the input weight of the tobacco leaves and the output weight of the tobacco shreds. Based on the difference between the input weight and the output weight measured by the weighing module, the control module runs or stops the cleaning component 220.

[0030] The tobacco leaf shredded discharging control system of the above structure, when in use, vertically places the horizontally stacked tobacco leaves into the feed box 100, the sorting and conveying assembly 110 separates the stacked tobacco leaves into single tobacco leaves, and conveys the scattered tobacco leaves to the shredded box 200, and then the shredded assembly 210 continuously cuts the tobacco leaves, and finally, the shredded tobacco produced after the tobacco leaves are cut is output to the shredded box 200 through the discharging assembly. Among them, based on the weight difference measured by the weighing module, the control module determines whether there is residual shredded tobacco in the shredded box 200, so as to timely operate the cleaning assembly 220 to clean the residual shredded tobacco, which is conducive to reducing the manual cleaning operation and further improving the production efficiency. The above structure can integrate the sorting, feeding, shredding, discharging and cleaning into one, improve the integration of the equipment, greatly reduce the manual operation, thereby realizing the automated processing from tobacco leaf raw materials to finished tobacco shredded products, which is conducive to improving the production efficiency and automation level of tobacco shredding.

[0031] See also Figures 1 to 5Further, the sorting and conveying assembly 110 includes a plurality of mounting cylinders 111 extending in the vertical direction, each mounting cylinder 111 is movably provided with a telescopic cylinder 112, a sealed cavity 113 is defined between the mounting cylinder 111 and the telescopic cylinder 112, the cavity 113 is connected with a positive pressure assembly through an air inlet pipe 114, the cavity 113 is connected with a negative pressure assembly through an air outlet pipe 115, the air inlet pipe 114 is provided with a first switch valve 116, the air outlet pipe 115 is provided with a second switch valve 117, and the first switch valve 116 and the second switch valve 117 are electrically connected to the control module. Specifically, when the control module opens the first switch valve 116 of the corresponding telescopic cylinder 112 and closes the second switch valve 117, the positive pressure assembly transports air to the cavity 113 through the air inlet pipe 114, so that the cavity 113 forms a positive pressure area to push the telescopic cylinder 112 to move upward. When the control module closes the first switch valve 116 of the corresponding telescopic cylinder 112 and opens the second switch valve 117, the negative pressure component extracts the air in the cavity 113 through the air outlet pipe 115, so that the cavity 113 forms a negative pressure area to drive the telescopic cylinder 112 to move downward. Through the above structure, the control module can control the two adjacent telescopic cylinders 112 to produce different telescopic states, thereby driving the stacked tobacco leaves to produce vertical movement, and then realize the vertical displacement movement of the two horizontally stacked tobacco leaves, which is conducive to separating the two tobacco leaves from each other and making the dispersed tobacco leaves between the two adjacent telescopic cylinders 112. It can be understood that the positive pressure component and the negative pressure component are existing fresh air systems. Among them, the negative pressure fresh air system extracts the air in the cavity 113 by forced exhaust, so that a negative pressure area is formed inside the cavity 113, thereby driving the telescopic cylinder 112 to retract. The positive pressure fresh air system sends external air into the cavity 113 through forced air supply to form a positive pressure area, thereby driving the telescopic cylinder 112 to extend.

[0032] See also Figures 2 to 4 , further, the lower end of the mounting tube 111 is connected with a spline shaft 118, the telescopic tube 112 is provided with a groove that slides with the spline shaft 118, the lower end of the spline shaft 118 is connected with a motor 119, and the motor 119 is electrically connected with a control module. Specifically, the mounting tube 111 is provided with a mounting groove with a notch facing upward, and the bottom wall of the telescopic tube 112 blocks the notch to form a closed cavity 113, so as to drive the telescopic tube 112 to reciprocate in the vertical direction by changing the size of the cavity 113. Among them, the telescopic tube 112 can be telescoped relative to the mounting tube 111 by using the spline shaft 118, which is conducive to standardizing the moving direction of the telescopic tube 112, and is also conducive to the transmission of the output torque of the motor 119 to drive the telescopic tube 112 to rotate.

[0033] See also Figure 1Furthermore, a camera 120 is provided inside the feed box 100, and the camera 120 is electrically connected to the control module. Based on the photographed image of the camera 120, the control module operates the corresponding motor 119. Specifically, the camera 120 takes a photo of the feed box 100 downward, and the control module includes a processing unit for analyzing and processing the image, thereby using the processing unit to identify the position of the tobacco leaves, and using an algorithm to plan the conveying path of the tobacco leaves, thereby driving the corresponding motor 119 on the path to operate to drive the multiple telescopic cylinders 112 to rotate, which is conducive to driving the scattered tobacco leaves to be conveyed to the input port 101 under the action of friction, and then inputting the tobacco leaves sorted into single sheets into the inside of the cutting box 200 for cutting.

[0034] See also Figure 2 , Figure 4 and Figure 5 , further, a first weight sensor 130 is provided at the top of the telescopic cylinder 112, the first weight sensor 130 is electrically connected to the control module, and a friction layer is provided on the side wall of the top of the telescopic cylinder 112. Specifically, when in use, the tobacco leaves stacked in the horizontal direction are vertically placed into the feed box 100, and the first weight sensor 130 at the top of the telescopic cylinder 112 generates a pressure signal and feeds back to the control module, and the control module determines the presence of tobacco leaves to operate the sorting and conveying assembly 110. Among them, the friction layer of the telescopic cylinder 112 is used to increase the friction force in contact with the tobacco leaves, thereby better driving the tobacco leaves to move in the vertical direction. It can be understood that the friction layer can be a rubber ring sleeved on the telescopic cylinder 112, which will not be described in detail here.

[0035] See also Figure 1 and Figure 5 Further, the feed box 100 is provided with an input port 101 connected to the shredder box 200, and the shredder assembly 210 includes a plurality of first cutter racks 211 and second cutter racks 212 rotatably arranged in the shredder box 200, wherein the first cutter rack 211 is transversely arranged below the input port 101, and the second cutter rack 212 is longitudinally arranged below the first cutter rack 211. Specifically, the first cutter rack 211 and the second cutter rack 212 include rotating rollers, and a plurality of cutters are arranged on the periphery of the rotating rollers, so that the cutters are staggered during the rotating process of the rotating rollers to cut tobacco leaves, and the first cutter racks 211 and the second cutter racks 212 distributed up and down are used to increase the cutting of tobacco leaves in different directions, which is conducive to better cutting tobacco leaves into tobacco shreds.

[0036] See also Figure 1Furthermore, a discharge port is provided on the side of the cutting box 200, and the discharge assembly includes a guide plate 230 and a collection box 231. The guide plate 230 is connected obliquely to the inner side wall of the cutting box 200, the second cutting knife frame 212 is located above the guide plate 230, and the collection box 231 is provided outside the cutting box 200.

Among them, the discharge port is connected to an inclined pipe, and the inclined pipe is provided with a third switch valve electrically connected to the control module, so that the output amount of the tobacco is controlled by opening or closing the third switch valve.

[0037] Furthermore, the feed box 100 is provided with an installation box 140, the sorting and conveying component 110 is arranged in the installation box 140, and the weighing module includes a second weight sensor and a third weight sensor, the second weight sensor is arranged in the collecting box 231 to measure the input weight of the tobacco leaves, and the third weight sensor is arranged in the installation box 140 to measure the output weight of the tobacco shreds, and the second weight sensor and the third weight sensor are electrically connected to the control module, so that by comparing the difference between the input weight and the output weight, the control module can judge whether there are any tobacco shreds remaining, so that the control module can run the cleaning component 220 for cleaning in time.

[0038] See also Figure 1 Further, the cleaning component 220 includes a fan 221, the fan 221 is electrically connected to the control module, the control module is used to control the forward and reverse rotation of the fan 221, the fan 221 is connected to a cleaning tube 222, and a filter 223 is provided at the output end of the cleaning tube 222, so that the fan 221 is used to blow or inhale the inside of the cutting box 200, which is conducive to generating an airflow that can clean the tobacco. Among them, when the fan 221 rotates forward, it can generate an airflow blowing into the cutting box 200, which is conducive to blowing off the tobacco remaining on the first cutting rack 211 and the second cutting rack 212 in the cutting box 200. When the fan 221 is reversed, it can generate a suction airflow that drives the tobacco leaves in the feed box 100 to fall into the cutting box 200, further improving the efficiency of tobacco leaf transportation and cutting.

[0039] See also Figure 1 and Figure 6Furthermore, the control module includes an error judgment unit, which is used to set a threshold value of the weight difference. If the difference measured by the weighing module is less than the threshold value, the control module controls the sorting and conveying component 110 and the shredding component 210 to operate. If the difference measured by the weighing module is equal to or greater than the threshold value, the control module controls the sorting and conveying component 110 and the shredding component 210 to stop operating, and the control module controls the cleaning component 220 to operate. Specifically, by setting the threshold value of the difference, the error judgment unit can monitor the weight difference between tobacco raw materials and tobacco shreds in real time, thereby ensuring the accuracy of material consumption during the production process. When the difference does not reach the threshold value, it means that there are still unprocessed tobacco raw materials or uncollected tobacco shreds. At this time, continuing to operate the sorting and conveying component 110 and the shredding component 210 can effectively avoid the waste of raw materials and the loss of tobacco shreds.
