[0002] The thick pulp tobacco sheet production line adopts tobacco powder pulping technology. Its basic principle is to grind the tobacco sheets into the required particle size. In order to better grind, the finished tobacco sheets need to be pre-ground into 3-5mm broken tobacco sheets and then undergo subsequent medium crushing and fine grinding to obtain tobacco powder.
[0003] When preparing crushed tobacco flakes, bridging agglomerates may form due to reasons such as meshing arches (arches formed by mutual meshing to reach a force balance state) and compression arches (arches caused by the increase in consolidation strength due to the pressure of the silo), which may easily lead to blockage of the silo. Blockages are very likely to occur at the connection between the silo and the pipeline. Feeding inside the pipeline relies on negative pressure, and unstable negative pressure can easily lead to blockage inside the pipeline, which affects the accuracy of the formula ratio.
[0004] Therefore, there is an urgent need to provide a tobacco material crushing system to monitor the feeding process during the preparation of broken tobacco sheets, so that timely warnings can be given when blockage occurs at the connection between the silo and the pipeline or inside the pipeline, avoiding excessive blockage that affects subsequent production.

[0035] like Figures 1 to 4 As shown, this embodiment provides a tobacco material crushing system, which includes a crusher 10, a buffer tank 20, a vacuum loader, a negative pressure sensor 40 and a level meter 60. The silo of the crusher 10 and the vacuum loader are connected through a first pipe. The vacuum loader is arranged above the buffer tank 20 and is connected to the buffer tank 20. The vacuum loader is used to suck the broken tobacco pieces from the crusher 10 into the buffer tank 20; the negative pressure sensor 40 is arranged in the vacuum loader, which is used to detect the negative pressure value in the first pipe; the level meter 60 is arranged in the silo, which is used to monitor whether broken tobacco pieces accumulate at the connection between the silo and the first pipe.
[0036] A crusher 10 is set to process the tobacco flakes into broken tobacco flakes, and then a vacuum loader is used to provide negative pressure to suck the broken tobacco flakes into the buffer tank 20; by setting a negative pressure sensor 40, the negative pressure in the first pipe is detected before the vacuum loader is loaded to ensure that the negative pressure conditions for loading are met. The negative pressure sensor 40 can also monitor the negative pressure of the first pipe in real time during the loading process; by setting a level meter 60 to detect whether there is accumulation of broken tobacco flakes at the connection between the silo and the first pipe, according to the measurement value of the negative pressure sensor 40 and the measurement value of the level meter 60, it can be judged whether there is blockage at the connection between the silo and the first pipe and inside the first pipe so as to provide a timely warning to avoid excessive blockage affecting subsequent production. The level meter 60 can be a rotary level meter. The rotary level meter has obvious advantages over ordinary level meters in terms of measurement accuracy, stability and application range through its unique mechanical rotation detection method and optimized design.
[0037] Specifically, the crusher 10 also includes a body for processing shredded tobacco, and a pneumatic hammer is provided in the body. The pneumatic hammer is used to impact the tobacco to obtain shredded tobacco. By using a pneumatic hammer and utilizing the principle of aerodynamics, the air supply pressure can be adjusted to change the force of the impact, and the outer wall of the crusher 10 body can be struck, which helps prevent the shredded tobacco from adhering, clogging, and bridging in the crusher 10 body. Specifically, the crusher 10 body is provided with a rotor and a hammer shaft connected to the rotor. The rotor can drive the hammer shaft to rotate. The hammer shaft is circumferentially provided with hammer heads, and multiple hammer heads are circumferentially spaced around the hammer shaft. The hammer heads and the hammer shaft rotate synchronously, and the high rotation operation is used to impact and crush the tobacco to obtain shredded tobacco.
[0038] Since the discharge speed at the silo outlet is inconsistent with the feeding speed inside the first pipe, the connection between the silo and the first pipe is prone to blockage. The crusher 10 also includes a screw conveying structure 11, which is connected to the silo. The screw conveying structure 11 can convey the broken tobacco flakes into the silo. By setting up the screw conveying structure 11, the screw conveying structure 11 can gradually convey the broken tobacco flakes to the silo, and the broken tobacco flakes fall from the outlet of the silo into the first pipe to obtain a stable conveying amount of broken tobacco flakes. The conveying amount of the screw conveying structure 11 can match the feeding amount of the vacuum loader to avoid a large amount of broken tobacco flakes being blocked in the silo or at the connection between the silo and the first pipe.
[0039] In this embodiment, the main body is connected to the silo via a screw conveying structure 11. The main body is located above the screw conveying structure 11, allowing the broken tobacco pieces to fall directly into the screw conveying structure 11. By arranging the main body above the screw conveying structure 11, the broken tobacco pieces fall directly into the screw conveying structure 11 and are transported into the silo at a stable delivery rate by the screw conveying structure 11, and then reach the first pipe through the silo outlet.
[0040] To better detect the presence of cigarette fragments in the first pipe, the tobacco material crushing system further includes a detection sensor 50, which is disposed on the first pipe and is used to detect the presence of cigarette fragments in the first pipe. The detection sensor 50 detects the presence of cigarette fragments in the first pipe. If no cigarette fragments are present in the first pipe, a blockage is detected, triggering an alarm and controlling the crusher 10 to stop crushing.
[0041] In this embodiment, the detection sensor 50 is a photoelectric sensor, which is provided with a glass window for observation; the photoelectric sensor includes a transceiver 51 and a reflector 52, which are arranged on both sides of the first pipe relative to each other, the transceiver 51 is used to emit light or receive light, and the reflector 52 is used to receive light emitted from the transceiver 51 and reflect the light back to the transceiver 51.
[0042] By setting up a photoelectric sensor, a quick response can be achieved, and non-contact measurement of broken cigarettes can be realized, which will not affect the quality of the broken cigarettes and can provide high-precision measurement results; the glass window of the photoelectric sensor can observe the changes in light intensity. When light is irradiated on the broken cigarettes, the changes in light intensity on the broken cigarettes will be captured by the photoelectric element of the photoelectric sensor and then converted into an electrical signal, accurately measuring the changes in light intensity and thus reflecting the changes in the broken cigarettes in the first pipe.
[0043] Furthermore, the vacuum loader includes a blanking device 32, a vacuum pump 31 and a second pipeline. The blanking device 32 is connected to the buffer tank 20, the hopper of the crusher 10 is connected to the blanking device 32 through the first pipeline, the vacuum pump 31 and the blanking device 32 are connected through the second pipeline, the negative pressure sensor 40 is arranged on the second pipeline, and the vacuum pump 31 is used to adjust the gas pressure and provide negative pressure.
[0044] By providing a vacuum pump 31 and a blanking device 32 in coordination, when the blanking device 32 is closed, the vacuum pump 31 provides negative pressure through the second pipe, causing the broken cigarette pieces to be sucked into the blanking device 32 through the first pipe. The blanking device 32 then automatically opens, allowing the broken cigarette pieces to automatically enter the buffer tank 20, thus completing the loading process. It is understood that the principles of the blanking device 32 and the vacuum pump 31 for loading are well known in the art and will not be further elaborated here.
[0045] Optionally, a fine grinding structure is provided within the buffer tank 20 for finely grinding the tobacco flakes into tobacco powder; a filter is also provided within the buffer tank 20 for filtering the tobacco powder. The fine grinding structure and filter allow the tobacco flakes to be converted into tobacco powder, and the tobacco powder filtration helps remove impurities and ensure uniform tobacco powder particles after filtration.
[0046] The following is the specific installation and use process of the smoke material system:
[0047] First, the crusher 10 is connected to the buffer tank 20. This step is usually completed by using an appropriate first pipe and connector to ensure that the connection is tight and leak-free to ensure that the crushed cigarette pieces can smoothly enter the buffer tank 20.
[0048] Next, the buffer tank 20 is connected to the blanking device 32 and the vacuum pump 31. This step also requires ensuring a tight connection to prevent gas or liquid leakage. When connecting, care should be taken to maintain the airtightness of the system to ensure that the vacuum pump 31 can work effectively.
[0049] Finally, the tobacco material crushing system is checked to ensure that all connections are leak-free, and then the vacuum pump 31 is started and operation begins. This step is key to ensuring the normal operation of the entire system, including checking the operating status of the vacuum pump 31, the working condition of the buffer tank 20, and the performance of the crusher 10.
[0050] Throughout the connection process, attention should be paid to safe operation to avoid improper operation that may cause equipment damage or personal injury. In addition, depending on the specific application scenario and equipment type, other factors may need to be considered, such as the length, diameter, and material of the first pipe, to ensure system efficiency and safety.
[0051] Before starting, a negative pressure detection is performed using a negative pressure sensor 40. If the operating conditions are not met, an alarm will be issued to remind the operator to check the equipment to prevent the risk of subsequent blockage. A pneumatic hammer is used to prevent the adhesion, blockage and bridging of broken tobacco pieces in the crusher 10 body, and a screw conveying structure 11 is added to obtain a stable conveying amount of broken tobacco pieces. During operation, a level meter 60 is used to detect the accumulation state of broken tobacco pieces at the connection between the silo and the first pipeline. If there is accumulation, the crushing is stopped, and the negative pressure value is monitored in real time using the negative pressure sensor 40. Once the negative pressure value exceeds the set range, an alarm is triggered and the crushing is stopped. A detection sensor 50 is used to detect whether there are broken tobacco pieces in the first pipeline. If there are no broken tobacco pieces, an alarm is triggered and the crushing is stopped.
[0052] The smoke material crushing system provided in this embodiment realizes monitoring before startup and during the entire operation process, thereby being able to effectively monitor material blockage and issue early warnings in a timely manner, thereby avoiding equipment shutdown and waste of raw materials due to material blockage.
[0053] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
