The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this patent.

[0060] A flap valve controls the flow of fluid by raising or lowering the valve or rotating it. When the flap valve needs to be closed, the flap will rotate or rise to a position perpendicular to the direction of fluid flow, thereby cutting off the fluid passage and preventing the fluid from passing through. This design mechanism enables the flap valve to effectively prevent the backflow of fluid.

[0061] Specifically, the flap valve enhances its flow diversion capacity through physical obstruction. When closed, the flap directly blocks the backflow path of the fluid. Because the flap is perpendicular to the fluid flow direction, it forms a robust physical barrier, preventing the fluid from flowing backward through the valve.

[0062] Specifically, flap valves typically have good sealing performance because the flaps are made of special sealing materials such as rubber and polytetrafluoroethylene, which allow the flap valve to fit tightly when closed, forming an effective sealing layer and further preventing fluid leakage and backflow.

[0063] Specifically, the flap valve is equipped with a two-way sealing structure, which means that sealing devices are installed on both sides of the valve. This design not only improves the sealing performance of the valve, but also makes the valve more reliable in preventing backflow.

[0064] There are two common methods for preparing fabric: flat-lay fabric and stacked fabric.

[0065] Specifically, the feeding process of the cabinet-type feeder in the stacking material distribution system is divided into front half cabinet feeding and rear half cabinet feeding. When the storage tank starts working, the front half cabinet feeding is executed first. When the material accumulates to a certain height, the diffuse reflection photoelectric switch under the front of the spreading trolley receives the material layer signal and sends a high-level signal to the PLC. Then, the spreading trolley executes a reverse command. When the diffuse reflection photoelectric switch receives the material layer signal, it indicates that the front half cabinet feeding is over. The PLC issues a command to feed to the rear half cabinet, and the spreading trolley moves towards the head of the cabinet. At the same time, the conveyor belt in the spreading trolley starts to run in reverse. This continues until the spreading trolley senses the reverse spreading limit switch at the rear of the cabinet, and the rear diffuse reflection photoelectric switch receives the material layer signal, indicating that the rear half cabinet feeding is over.

[0066] Specifically, another feeding method in tobacco sheet production lines is flat-lay feeding. There are two types of flat-lay feeding: unidirectional and bidirectional. Unidirectional flat-lay feeding involves two cabinets sharing one feeding crane and one discharge port, and is often used for feeding top-loading cabinets. Bidirectional flat-lay feeding is the most commonly used method in production lines. Each cabinet has its own feeding crane, and several cabinets share a single distribution crane. The feeding crane moves back and forth from the front to the back of the cabinet. The advantages of flat-lay feeding are: thorough mixing of materials within the cabinet; balanced moisture content; reduced equipment costs; and high space utilization. The disadvantages of flat-lay feeding are: a long feeding-to-discharging cycle; and prolonged material residence time within the cabinet, leading to easy loss of surface moisture.

[0067] Example

[0068] like Figure 1 As shown, a cabinet-finding system for tobacco sheet storage cabinets includes a conveying device 100, a spreading device 200, a feeding device 300, and a storage device 400. Tobacco sheets enter the conveying device 100 and are fed from the conveying device 100 into the spreading device 200. The spreading device 200 performs a reciprocating motion to find and feed the sheets to the designated feeding device 300, and then the feeding device 300 feeds them into the corresponding storage device 400. In the axial direction, the rear section of the conveying device 100 is positioned above the spreading device 200, the spreading device 200 is positioned above the feeding device 300, and the feeding device 300 is positioned above the storage device 400.

[0069] Specifically, the fabric feeding device 200 is equipped with a timing mechanism 270, and the conveying device 100 is equipped with a flow limiting mechanism 150. The timing mechanism 270 and the flow limiting mechanism 150 achieve the technical effect of preventing material blockage.

[0070] Specifically, the timing mechanism 270 is equipped with a standard cabinet-finding time T1. When the standard cabinet-finding time T1 > the actual cabinet-finding time T2, the cabinet-finding system is in normal condition; when the standard cabinet-finding time T1 ≤ the actual cabinet-finding time T2, the cabinet-finding system is in anti-blocking mode.

[0071] like Figure 2 As shown, the conveying device 100 includes a first conveyor belt 110, a first motor 120, a second conveyor belt 130, a second motor 140, a flow limiting mechanism 150, and a first collection hopper 160. The flow limiting mechanism 150 includes a flap valve 152 and a flow limiting switch 151. The first conveyor belt 110 and the second conveyor belt 130 are set with a height difference.

[0072] Specifically, the front section of the first conveyor belt 110 is lower than the rear section of the first conveyor belt 110, the front section of the second conveyor belt 130 is lower than the rear section of the first conveyor belt 110, and the front section of the second conveyor belt 130 is lower than the rear section of the second conveyor belt 130. The first motor 120 is located at the end of the first conveyor belt 110, the second motor 140 is located at the end of the second conveyor belt 130, the flow limiting mechanism 150 is located between the end of the first conveyor belt 110 and the front end of the second conveyor belt 130, the flap valve 152 is located below the flow limiting switch 151 and connected to the flow limiting switch 151, and the first hopper 160 is located below the flow limiting mechanism 150.

[0073] The first conveyor belt 110 and the second conveyor belt 130 move laterally. The first conveyor belt 110 is positioned after the tobacco drying machine, and the second conveyor belt 130 is positioned before entering the constant temperature and humidity workshop. Tobacco sheets exiting the drying machine enter the front section of the first conveyor belt 110. Driven by the first motor 120, the tobacco sheets are transported from a lower position to a higher position on the first conveyor belt 110, and fall onto the front section of the second conveyor belt 130 under the influence of gravity at the end of the first conveyor belt 110. Driven by the second motor 140, the tobacco sheets are transported from a lower position to a higher position on the second conveyor belt 130, and fall onto the fabric conveyor belt 210 under the influence of gravity at the end of the second conveyor belt 130.

[0074] like Figure 3 As shown, the fabric feeding device 200 includes a fabric conveyor belt 210, a fabric carriage 220, a third motor 230, a fourth motor 240, a track frame 250, a second collection hopper 260, and a timing mechanism 270. The fabric carriage 220 includes wheels 221 at the bottom, and the track frame 250 includes a travel track 251.

[0075] Specifically, the fabric spreading device 200 is positioned above the feeding device 300, and is lower than the end of the second conveyor belt 130, allowing the tobacco sheets to fall from the end of the second conveyor belt 130 into the fabric conveyor belt 210 under gravity. The conveyor belt is mounted on the fabric carriage 220, and wheels 221 are provided at the bottom of the fabric carriage 220. The wheels 221 reciprocate on the travel track 251. The third motor 230 is located in the middle of the end of the fabric conveyor belt 210, and the fourth motor 240 is located on the side of the fabric conveyor belt 210. A timing mechanism 270 is provided at the end of the fabric carriage 220 away from the fourth motor 240. The second collection hopper 260 is located below the end of the fabric conveyor belt 210 and is used to collect the tobacco sheets that fall from the fabric spreading device 200.

[0076] Specifically, the fabric conveyor belt 210 moves in the longitudinal direction. The tobacco sheets fed onto the fabric conveyor belt 210 stay and wait to be searched for. The fabric conveyor belt 210 moves under the drive of the fourth motor 240. The tobacco sheets that fall into the conveyor belt 210 are sent to the rear section of the fabric conveyor belt 210. When the fabric carriage 220 starts searching for the cabinet, the fourth motor 240 stops driving the fabric conveyor belt 210.

[0077] Specifically, such as Figure 4 As shown, in this embodiment, the track frame 250 is a rectangular structure, and the trolley track 251 is set on the two long sides of the rectangular frame in the horizontal direction. Driven by the third motor 230, the wheels 221 at the bottom of the fabric cart frame 220 reciprocate on the trolley track 251 to find the storage device 400 that is not full. The actual time consumed in the cabinet finding process is recorded as the actual cabinet finding time T2.

[0078] Specifically, during the reciprocating motion of the fabric carrier 220 to find the storage unit, the fabric conveyor belt 210 stops moving; after the fabric device 200 finds the storage unit 400 that is not full, the fabric device 200 moves above the corresponding storage unit 400 and connects with the feeding device 300 between the fabric device 200 and the storage unit 400. The number of feeding devices 300 is the same as the number of storage units 400.

[0079] Specifically, after the tobacco sheet is transported to the end of the fabric conveyor belt 210, it falls into the target feed port under gravity. It then falls onto the target feed conveyor belt, which moves longitudinally to send the tobacco sheet into the unfilled target storage tank.

[0080] Specifically, in this embodiment, there are four storage devices 400, namely the first storage cabinet 410, the second storage cabinet 420, the third storage cabinet 430 and the fourth storage cabinet 440, which are arranged in sequence along the horizontal direction with the end away from the fourth motor 240 as the starting point.

[0081] As is easily understood, this embodiment has four feeding devices 300, and the arrangement of the four feeding devices 300 is the same as the arrangement of the four storage devices 400.

[0082] Specifically, taking the first feeding device as an example, the first feeding device includes a first feeding inlet 310, a first feeding conveyor belt 320, and a first support frame 330. The first feeding inlet 310 is located in the hollow part of the track frame 250. The first feeding conveyor belt 320 is located below the first feeding inlet 310. The first feeding conveyor belt 320 and the first storage tank 410 are connected by the first support frame 330. After the fabric carrier frame 220 reciprocates under the drive of the third motor 230, it finds the unfilled first storage tank 410, and the wheels 221 immediately stop, so that... The end of the fabric conveyor belt 210 is aligned with the first feed inlet 310 along the axial direction. After alignment, the fourth motor 240 starts to drive the fabric conveyor belt 210 to move. The tobacco sheet that stays on the fabric conveyor belt 210 is conveyed towards the end of the fabric conveyor belt 210 along the longitudinal direction. After the tobacco sheet is conveyed to the end of the fabric conveyor belt 210, it falls into the first feed inlet 310 under gravity. It falls onto the first feed conveyor belt 320 through the first feed inlet 310. Then the first feed conveyor belt 320 moves along the longitudinal direction to send the tobacco sheet into the first storage tank 410.

[0083] Specifically, the fabric feeding device 200 is equipped with a timing mechanism 270, which can be set to a standard cabinet-finding time T1. During the cabinet-finding process, the tobacco sheets remain on the fabric conveyor belt 210 and the fabric conveyor belt 210 stops moving. When the actual cabinet-finding time T2 is too long, the tobacco sheets on the fabric conveyor belt 210 will accumulate more and more, which will cause serious blockage.

[0084] Specifically, when the actual cabinet search time T2 is greater than or equal to the set standard cabinet search time T1, the fourth motor 240 will force the fabric conveyor belt 210 to transport the accumulated tobacco sheets. At this time, the fabric carriage 220 is still reciprocating to search for an unfilled storage cabinet. After the accumulated tobacco sheets are transported to the end of the fabric conveyor belt 210 in the longitudinal direction, since no corresponding storage cabinet and corresponding feeding device 300 are found, the accumulated tobacco sheets fall from the hollow parts of the track frame 250 other than the feeding port to the bottom second collection hopper 260 under the action of gravity.

[0085] Specifically, in this embodiment, the standard cabinet search time set by the timing mechanism 270 is 50 seconds.

[0086] Specifically, when the actual cabinet search time T2 is less than the standard cabinet search time T1, the cabinet search system is in normal condition.

[0087] Specifically, when the actual cabinet-finding time T2 is greater than or equal to the standard cabinet-finding time T1, the cabinet-finding system enters the anti-blocking state, and the flow-limiting mechanism 150 is activated simultaneously. The flow-limiting mechanism 150 is set between the first conveyor belt 110 and the second conveyor belt 130 in the conveying device 100. The tobacco sheet is transported from a low position to a high position under the drive of the first motor 120 to the first conveyor belt 110. There is a height difference between the rear section of the first conveyor belt 110 and the front section of the second conveyor belt 130. When the tobacco sheet is transported to the end of the first conveyor belt 110, it falls to the front section of the second conveyor belt 130 under the action of gravity.

[0088] Specifically, the second conveyor belt 130 is also a structure set from low to high, that is, the front section of the second conveyor belt 130 is lower than the rear section of the second conveyor belt 130. The falling tobacco sheets first fall into the front end of the second conveyor belt 130 under the action of gravity, and then the second motor 140 drives the second conveyor belt 130 to transport the tobacco sheets from the front end to the rear end. A current limiting switch 151 is provided between the front end of the second conveyor belt 130 and the end of the first conveyor belt 110.

[0089] Specifically, the flow limiting switch 151 is a baffle plate used to prevent tobacco sheets from falling into the flow limiting mechanism 150 under normal transportation conditions. In the event of material blockage, the flow limiting switch 151 is in the open state, and the flap valve 152 starts to operate. At this time, some tobacco sheets transported from the end of the first conveyor belt 110 fall into the flap valve 152 through the flow limiting switch 151. The flap valve 152 quickly stirs the tobacco sheets and causes them to fall into the first collection hopper 160. Another part of the tobacco sheets is normally fed into the rear section of the second conveyor belt 130 and the material distribution device 200, thereby achieving the effect of diversion and anti-blockage.
