Description

Technical Field

[0001] This invention relates to the technical field of tobacco processing equipment, and more particularly to a tobacco leaf shredding and discharge control system. Background Technology

[0002] Currently, the tobacco processing industry, as a crucial link in cigarette production, directly impacts the quality and market competitiveness of cigarette products through its technological level and production efficiency. In recent years, with the continuous development of automation technology, automated equipment, such as automatic feeders and automatic shredders, has been introduced into tobacco processing during the shredding process. While these devices have improved tobacco production efficiency to some extent, problems remain, including low levels of intelligence and poor system integration. For example, during tobacco feeding, preliminary sorting is usually required beforehand to separate the tobacco leaves into loose pieces that enter the hopper. However, existing systems largely rely on manual labor for this preliminary sorting, which is not only labor-intensive but also prone to errors due to human factors, such as incomplete sorting and raw material mixing, affecting the subsequent shredding quality. Summary of the Invention

[0003] To address the above shortcomings, this invention proposes a tobacco leaf shredding and discharge control system, which can automatically sort, feed, shred, and discharge tobacco leaves, and clean up residual tobacco shreds, reducing the proportion of manual operation in the system and improving the efficiency of tobacco leaf shredding.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The tobacco leaf shredding and discharge control system according to an embodiment of the present invention has at least the following beneficial effects: In use, horizontally stacked tobacco leaves are vertically placed into the feeding box. The sorting and conveying component separates the stacked tobacco leaves into individual leaves and conveys the loose tobacco leaves to the shredding box. Subsequently, the shredding component continuously cuts the tobacco leaves. Finally, the tobacco shreds produced after cutting are output to the shredding box through the discharge component. Based on the weight difference measured by the weighing module, the control module determines whether there are residual tobacco shreds in the shredding box, and thus promptly operates the cleaning component to clean the residual tobacco shreds, which helps reduce manual cleaning operations and further improves production efficiency. Using the above structure, sorting, feeding, shredding, discharging, and cleaning can be integrated into one unit, improving the integration of the equipment, significantly reducing manual operations, and thus realizing automated processing from raw tobacco leaves to finished tobacco shreds, which is beneficial to improving the production efficiency and automation level of tobacco processing.

[0029] See Figures 1 to 6 A tobacco leaf shredding and discharge control system includes: a feeding box 100, a shredding box 200, and a control module. The feeding box 100 has a sorting and conveying assembly 110 inside, which is used to sort and separate horizontally stacked tobacco leaves and convey them to the next workstation. The shredding box 200 is located below the feeding box 100. Inside the shredding box 200, from top to bottom, are a shredding assembly 210, a cleaning assembly 220, and a discharge assembly. The shredding assembly 210 is used to discharge the tobacco leaves from the sorting and conveying assembly. The tobacco leaves conveyed by component 110 are shredded. The cleaning component 220 is used to clean the tobacco shreds remaining after shredding. The discharge 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. The control module is also electrically connected to a 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 starts or stops the cleaning component 220.

[0030] The tobacco leaf shredding and discharge control system described above operates by vertically placing horizontally stacked tobacco leaves into the feeding box 100. The sorting and conveying component 110 separates the stacked tobacco leaves into individual sheets and transports the loose tobacco leaves to the shredding box 200. Subsequently, the shredding component 210 continuously cuts the tobacco leaves. Finally, the tobacco shreds produced after cutting are output to the shredding box 200 through the discharge component. Based on the weight difference measured by the weighing module, the control module determines whether there are any residual tobacco shreds in the shredding box 200, and promptly activates the cleaning component 220 to clean up the residual tobacco shreds, reducing manual cleaning operations and further improving production efficiency. This structure integrates sorting, feeding, shredding, discharge, and cleaning into one unit, improving equipment integration, significantly reducing manual operations, and achieving automated processing from raw tobacco leaves to finished tobacco shreds, thereby improving the production efficiency and automation level of tobacco processing.

[0031] See Figures 1 to 5Furthermore, the sorting and conveying assembly 110 includes multiple mounting cylinders 111 extending vertically. Each mounting cylinder 111 is movably equipped 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 to a positive pressure assembly via an air inlet pipe 114 and to a negative pressure assembly via an air outlet pipe 115. The air inlet pipe 114 is equipped with a first switching valve 116, and the air outlet pipe 115 is equipped with a second switching valve 117. The first switching valve 116 and the second switching valve 117 are electrically connected to a control module. Specifically, when the control module opens the first switching valve 116 of the corresponding telescopic cylinder 112 and closes the second switching valve 117, the positive pressure assembly delivers air to the cavity 113 through the air inlet pipe 114, thereby creating a positive pressure zone in the cavity 113 to push the telescopic cylinder 112 upward. When the control module closes the first switch valve 116 and opens the second switch valve 117 of the corresponding telescopic cylinder 112, the negative pressure component draws air out of the cavity 113 through the air outlet pipe 115, thereby creating a negative pressure zone in the cavity 113, which in turn drives the telescopic cylinder 112 to move downward. Through this structure, the control module can control two adjacent telescopic cylinders 112 to produce different telescopic states, thereby causing the stacked tobacco leaves to move vertically, and thus achieving vertical misalignment of two horizontally stacked tobacco leaves. This helps to separate the two tobacco leaves and ensures that the dispersed tobacco leaves are positioned 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. The negative pressure fresh air system, through forced exhaust, draws air out of the cavity 113 to create a negative pressure zone inside the cavity 113, thereby driving the telescopic cylinder 112 to retract. The positive pressure fresh air system forces air in from outside into the cavity 113 to create a positive pressure zone, thereby causing the telescopic cylinder 112 to extend.

[0032] See Figures 2 to 4 Furthermore, the lower end of the mounting cylinder 111 is connected to a splined shaft 118, and the telescopic cylinder 112 has a groove that slides with the splined shaft 118. The lower end of the splined shaft 118 is connected to a motor 119, and the motor 119 is electrically connected to a control module. Specifically, the mounting cylinder 111 has an upward-facing mounting groove, and the bottom wall of the telescopic cylinder 112 seals the groove to form a sealed cavity 113. By changing the size of the cavity 113, the telescopic cylinder 112 can be driven to reciprocate vertically. The splined shaft 118 enables the telescopic cylinder 112 to extend and retract relative to the mounting cylinder 111, which helps to regulate the movement direction of the telescopic cylinder 112 and facilitates the transmission of the output torque of the motor 119 to drive the telescopic cylinder 112 to rotate.

[0033] See Figure 1Furthermore, a camera 120 is installed inside the feed box 100. The camera 120 is electrically connected to the control module. Based on the image captured by the camera 120, the control module operates the corresponding motor 119. Specifically, the camera 120 takes a picture of the feed box 100 from below. The control module includes a processing unit that analyzes and processes the image. The processing unit identifies the position of the tobacco leaves and uses an algorithm to plan the conveying path of the tobacco leaves. This drives the corresponding motor 119 on the path to rotate, thereby rotating multiple telescopic cylinders 112. This facilitates the conveying of the spread-out tobacco leaves to the input port 101 under the action of friction, and then the sorted tobacco leaves are input into the shredder 200 for cutting.

[0034] See Figure 2 , Figure 4 and Figure 5 Furthermore, a first weight sensor 130 is provided at the top of the telescopic cylinder 112, and the first weight sensor 130 is electrically connected to the control module. A friction layer is provided on the side wall of the top of the telescopic cylinder 112. Specifically, in use, the horizontally stacked tobacco leaves are vertically placed into the feed box 100. The first weight sensor 130 at the top of the telescopic cylinder 112 generates a pressure signal and feeds it back to the control module. The control module determines the presence of tobacco leaves and operates the sorting and conveying assembly 110 accordingly. The friction layer of the telescopic cylinder 112 helps to increase the frictional force in contact with the tobacco leaves, thereby better driving the tobacco leaves to move vertically. It is understood that the friction layer can be a rubber ring fitted onto the telescopic cylinder 112, which will not be described in detail here.

[0035] See Figure 1 and Figure 5 Furthermore, the feeding box 100 is provided with an input port 101 communicating with the shredding box 200. The shredding assembly 210 includes several first cutter holders 211 and second cutter holders 212 rotatably disposed in the shredding box 200. The first cutter holders 211 are arranged laterally below the input port 101, and the second cutter holders 212 are arranged longitudinally below the first cutter holders 211. Specifically, the first cutter holders 211 and second cutter holders 212 include rotating rollers, and multiple cutters are arranged on the outer periphery of the rotating rollers, so that the cutters are staggered during the rotation of the rotating rollers to cut the tobacco leaves. The vertically distributed first cutter holders 211 and second cutter holders 212 increase the cutting of the tobacco leaves in different directions, which is beneficial to better cut the tobacco leaves into tobacco shreds.

[0036] See Figure 1Furthermore, the side of the shredding box 200 is provided with a discharge port. The discharge assembly includes a guide plate 230 and a collection box 231. The guide plate 230 is inclinedly connected to the inner wall of the shredding box 200. The second cutter holder 212 is located above the guide plate 230. The collection box 231 is located outside the shredding box 200. One end of the guide plate 230 extends through the discharge port and is located above the collection box 231. Thus, the guide plate 230 is used to transport the cut tobacco shreds to the discharge port, and the collection box 231 is used to collect the tobacco shreds in a timely manner. 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. The output amount of tobacco shreds 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 assembly 110 is located in the installation box 140, and the weighing module includes a second weight sensor and a third weight sensor. The second weight sensor is located in the collection box 231 to measure the input weight of the tobacco leaves, and the third weight sensor is located in the installation box 140 to measure the output weight of the tobacco shreds. 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 determine whether there is any tobacco shred residue, so that the control module can promptly run the cleaning assembly 220 to clean it.

[0038] See Figure 1 Furthermore, the cleaning component 220 includes a fan 221, which is electrically connected to a control module. The control module controls the forward and reverse rotation of the fan 221. The fan 221 is connected to a cleaning pipe 222, and a filter screen 223 is installed at the output end of the cleaning pipe 222. The fan 221 blows or sucks air into the shredding box 200, which helps generate an airflow capable of cleaning the tobacco. Specifically, when the fan 221 rotates forward, it generates an airflow that blows into the shredding box 200, effectively removing residual tobacco from the first cutter holder 211 and the second cutter holder 212 within the shredding box 200. When the fan 221 rotates in reverse, it generates a suction airflow that draws tobacco leaves from the feed box 100 into the shredding box 200, further improving the efficiency of tobacco leaf conveying and shredding.

[0039] See Figure 1 and Figure 6Furthermore, the control module includes an error judgment unit, which sets a threshold for the weight difference. If the difference measured by the weighing module is less than the threshold, the control module controls the sorting and conveying assembly 110 and the shredding assembly 210 to operate. If the difference measured by the weighing module is equal to or greater than the threshold, the control module controls the sorting and conveying assembly 110 and the shredding assembly 210 to stop operating, and the control module controls the cleaning assembly 220 to operate. Specifically, by setting a threshold for the difference, the error judgment unit can monitor the weight difference between the raw tobacco leaves and the shredded tobacco in real time, thereby ensuring the accuracy of material consumption during the production process. When the difference does not reach the threshold, it means that there are still raw tobacco leaves that have not been fully processed or shredded tobacco that have not been fully collected. In this case, continuing to operate the sorting and conveying assembly 110 and the shredding assembly 210 can effectively avoid waste of raw materials and loss of shredded tobacco.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
