Description

TECHNICAL FIELD

[0002] In the tobacco industry, cut tobacco as a core raw material, its quality and recycling efficiency has been the focus of the industry. With the continuous development of tobacco production process and the increasing demand for resource conservation and cost control, efficient and accurate cut tobacco separation technology is becoming increasingly important.

[0003] At present, the traditional cut tobacco separation method has many limitations. For example, the cut tobacco is extracted by manual method, the operator needs to use special knives to cut the cigarette paper, and shake the cigarette to shake out the cut tobacco inside and collect it.

[0034] The preferred embodiments of the present application are described below in conjunction with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0035] The first aspect of the embodiments of the present application provides a tobacco shred separating device; the second aspect of the embodiments of the present application provides a tobacco shred recycling device; and the third aspect of the embodiments of the present application provides a tobacco shred quality detection device.

[0036] The tobacco shred separating device can be applied to the tobacco shred recycling device and the tobacco shred quality detection device.

[0037] Specifically, referring to FIG. 1, Figures 1 to 4 The first aspect of the embodiments of the present application provides a tobacco shred separating device, which comprises a cigarette conveying mechanism, a tobacco shred separating mechanism, and a conveying roller.

[0038] In this embodiment, the conveying roller is arranged to match the tobacco shreds, and the tobacco shreds can be sequentially dropped from the discharge port, thereby realizing automatic conveying of the tobacco shreds, greatly improving the efficiency of tobacco shred separation, and reducing labor costs compared with manual methods.

[0039] The conveying bin is a container for accommodating the tobacco shreds, and can store a certain amount of tobacco shreds to provide a source of tobacco shreds for subsequent tobacco shred separation operations.

[0040] Specifically, the conveying bin has a funnel-shaped structure, which helps the tobacco shreds to naturally fall to the discharge port at the bottom of the bin under the action of gravity.

[0041] The bottom of the conveying bin 1 is rotatably provided with a conveying roller 2. The outer peripheral surface of the conveying roller 2 is provided with a plurality of grooves matched with the cigarette. The plurality of grooves are uniformly arranged along the circumferential direction of the conveying roller 2, and the shape and size of the plurality of grooves are matched with the cigarette. When the conveying roller 2 rotates, the cigarette will fall into the groove due to gravity. With the continuous rotation of the conveying roller 2, the cigarette will be conveyed to the next process, realizing the orderly conveying of the cigarette.

[0042] Specifically, the tobacco separation device further comprises a support frame, and the tobacco separation mechanism is arranged inside the support frame. The support frame is used to provide a stable operation space for the tobacco separation mechanism. The top of the support frame is horizontally provided with a bearing plate, which is a mounting base for firmly fixing the tobacco conveying mechanism to ensure the stability of the tobacco conveying process. In actual application scenarios, a driving motor is installed on the bearing plate. The driving motor can be a stepper motor or a servo motor, etc. The output shaft of the driving motor is mechanically connected to the conveying roller 2 through a suitable connection method (such as a shaft coupling, etc.). The driving motor drives the conveying roller 2 to rotate at a preset speed and direction through the output rotary power, thereby realizing the orderly conveying of the cigarette in the tobacco conveying mechanism.

[0043] Specifically, the bottom of the conveying roller 2 and the support frame are provided with a rotary platform 3, which is used to receive the cigarette falling from the groove of the conveying roller 2. At the same time, the rotary platform 3 can drive the cigarette to switch between two different positions, i.e. the first position and the second position. That is, the rotary platform 3 is a rotating work platform that sends the cigarette falling on it to different processing positions.

[0044] Specifically, a rotary motor is also arranged in the support frame, which can also be a stepper motor or a servo motor. In actual application scenarios, the rotary motor serves as a power source and is mechanically connected to the rotary platform 3 through a worm gear structure. The worm gear structure can effectively transmit and convert the output power of the rotary motor, thereby driving the rotary platform 3 to perform stable and precise rotary motion to meet the process requirements of the cigarette switching between different positions during the tobacco separation process.

[0045] Specifically, the outer peripheral side of the rotary platform 3 and the support frame are provided with a tobacco blowing assembly 4. When the cigarette is driven by the rotary platform 3 to the first position, the cigarette is opposite to the tobacco blowing assembly 4. The tobacco blowing assembly 4 can separate the tobacco from the cigarette by blowing air flow, etc., thereby realizing the recovery of the tobacco.

[0046] The outer circumferential side of the rotating platform 3 and the inner side of the support frame are further provided with a blowpipe assembly 5. When the cigarette is in the second position driven by the rotating platform 3, the cigarette is opposite to the blowpipe assembly 5. The blowpipe assembly 5 can further process the cigarette, for example, collecting the empty cigarette tube after the tobacco is separated by the blowpipe assembly 4. It should be noted that the blowpipe assembly 5 can also blow the empty cigarette tube off the rotating platform 3 by blowing air flow, so as to realize the recovery of the empty cigarette tube.

[0047] In some possible implementation embodiments disclosed in the present application, referring to Figure 3 As shown in the figure, the tobacco separation mechanism further comprises a support frame 6 and a clamp 7. The support frame 6 is arranged on the rotating platform 3 and is used to receive the cigarette falling from the groove of the conveying roller 2. The clamp 7 is arranged on one side of the support frame 6 along the length direction of the cigarette and is used to clamp the filter rod of the cigarette.

[0048] In this embodiment, the support frame 6 is arranged on the rotating platform 3 and is used to receive the cigarette falling from the groove of the conveying roller 2. This can ensure the accurate position of the cigarette when it is transferred from the conveying roller 2 to the rotating platform 3, provide a stable support basis for subsequent tobacco separation and other operations, ensure that the cigarette is in the correct processing position, and help to improve the stability and accuracy of the entire tobacco separation process. The clamp 7 is arranged on one side of the support frame 6 along the length direction of the cigarette and is used to clamp the filter rod of the cigarette. This can effectively fix the cigarette during the tobacco separation process, prevent the cigarette from shaking, shifting or even falling due to the action of the air flow of the blowpipe assembly 4, make the blowpipe operation more accurate, help to improve the effect and quality of tobacco separation, ensure that the tobacco can be more completely separated from the cigarette, and also avoid damage to the tobacco or the empty cigarette tube caused by the movement of the cigarette.

[0049] The support frame 6 is fixedly arranged on the rotating platform 3 and is used to receive the cigarette falling from the groove of the conveying roller 2.

[0050] Specifically, the support frame 6 is provided with a positioning groove for carrying the cigarette, and the positioning groove extends along the length direction of the cigarette. In an actual application scenario, as the conveying roller 2 rotates, the cigarette will fall from the groove of the conveying roller 2. At this time, the support frame 6 plays a role in receiving, ensuring that the cigarette can accurately fall in the predetermined position and prepare for subsequent tobacco separation and other operations. That is, the support frame 6 is equivalent to a transitional and positioning component, which ensures the positional accuracy of the cigarette in the entire tobacco separation process.

[0051] The rotary platform 3 is further provided with a clamp 7 fixed thereon, which is arranged opposite to the support frame 6 along the length direction of the cigarette. It can be understood that the cigarette includes a relatively fixed filter rod and a tobacco pipe, and tobacco is located in the tobacco pipe. Therefore, when separating the tobacco, air needs to be blown into the tobacco pipe through the filter rod to successfully blow out the tobacco in the tobacco pipe. In this process, the clamp 7 is used to clamp the filter rod to ensure the stability of the tobacco pipe and prevent it from shaking or moving, so that the tobacco separation operation can be smoothly and accurately performed.

[0052] Specifically, the clamp 7 can adopt an elastic jaw structure, and the inner side of the jaw is covered with a layer of rubber pad with a certain friction, which can firmly clamp the filter rod without damaging the surface of the filter rod. The opening and closing of the jaw can be controlled by a small pneumatic driving device, which is connected to an external air source through an air pipe. When the air source provides stable compressed air, the pneumatic driving device can accurately control the opening and closing action of the jaw according to the preset program. When the tobacco separation device is running, the cigarette first falls from the groove of the conveying roller 2 and accurately falls on the support frame 6 of the rotary platform 3. At this time, the rotary platform 3 starts to rotate to transport the support frame 6 carrying the cigarette to the corresponding position of the tobacco blowing assembly 4. At the same time, a control signal is sent to the pneumatic driving device, and after the driving device receives the signal, the clamp is quickly closed to tightly clamp the filter rod of the cigarette. Then, the tobacco blowing assembly 4 starts, and the high-speed airflow passes through the air nozzle to accurately blow air into the tobacco pipe through the filter rod. Due to the stable clamping of the clamp 7, the tobacco pipe remains in a stationary state, and the strong airflow can effectively blow out the tobacco in the tobacco pipe to realize the separation of the tobacco and the tobacco pipe. The separated tobacco can be collected in the tobacco collecting box 8 under the guidance of the airflow. When the tobacco separation is completed, the rotary platform 3 rotates again to transport the support frame 6 together with the clamp 7 clamping the empty tobacco pipe to the corresponding position of the blowing pipe assembly 5. At this time, the clamp is opened under the control of the pneumatic driving device, and the airflow blown by the blowing pipe assembly 5 acts on the empty tobacco pipe to blow it off from the support frame 6 and into the tobacco pipe collecting box 9.

[0053] In some possible implementation embodiments of the present application, as shown in Figure 3 The tobacco blowing assembly 4 includes a first air cylinder 41 and a first air nozzle 42, the first air cylinder 41 is connected with the first air nozzle 42, when the cigarette is in the first position, the first air cylinder 41 is used to drive the first air nozzle 42 to insert into the filter rod of the cigarette, and the first air nozzle 42 is used to blow air into the tobacco pipe of the cigarette to separate the tobacco in the tobacco pipe; the blowing pipe assembly 5 includes a second air cylinder 51 and a second air nozzle 52, the second air cylinder 51 is connected with the second air nozzle 52, when the cigarette is in the second position, the second air cylinder 51 is used to drive the second air nozzle 52 to approach the empty tobacco pipe, and the second air nozzle 52 is used to blow air into the empty tobacco pipe to blow the empty tobacco pipe off from the rotary platform 3.

[0054] In this embodiment, for the blowing filament assembly 4, the first air cylinder 41 drives the first air nozzle 42 to insert into the filter rod of the cigarette, which can accurately position the blowing position and directly blow air into the tobacco pipe. Compared with the traditional random blowing method, it greatly improves the efficiency and effect of tobacco separation, ensures that the tobacco can be blown out sufficiently, reduces the tobacco residue, and improves the tobacco recovery rate. At the same time, the accurate insertion of the filter rod blowing method avoids excessive disturbance and damage to the tobacco, maximizes the integrity and physical properties of the tobacco, and ensures the quality of the recovered tobacco, providing quality assurance for subsequent tobacco reuse. As for the blowing pipe assembly 5, the second air cylinder 51 drives the second air nozzle 52 to approach the empty tobacco pipe for blowing, which can accurately control the blowing force and direction, stably blow the empty tobacco pipe off the rotary platform 3, and avoid problems such as jamming and inaccurate falling position of the empty tobacco pipe during collection, thereby improving the success rate and efficiency of empty tobacco pipe collection.

[0055] When the rotary platform 3 drives the cigarette to the first position, the cigarette is opposite to the blowing filament assembly 4 at this time. The first air cylinder 41 starts to work, which is equivalent to a power source. Through the extension and retraction movement of itself, the first air nozzle 42 connected thereto moves towards the filter rod of the cigarette until it is inserted into the filter rod. After the first air nozzle 42 is inserted, it blows air into the tobacco pipe of the cigarette. Since the tobacco is located in the tobacco pipe, under the impact of the airflow, the tobacco is separated from the tobacco pipe, thereby achieving the purpose of extracting tobacco from the cigarette. For example, after receiving the instruction from the control system, the first air cylinder 41 rapidly extends the piston rod to push the first air nozzle 42 to accurately insert into the filter rod of the cigarette, and then high-pressure gas is sprayed from the first air nozzle 42 to blow the tobacco in the tobacco pipe out.

[0056] When the rotary platform 3 drives the cigarette (which becomes an empty tobacco pipe at this time) with separated tobacco to the second position, the empty tobacco pipe is opposite to the blowing pipe assembly 5. At this time, the second air cylinder 51 is started, and the second air cylinder 51 drives the second air nozzle 52 to approach the empty tobacco pipe. When the second air nozzle 52 reaches the appropriate position, it blows air to the empty tobacco pipe. Under the action of high-speed airflow, the empty tobacco pipe receives a horizontal force and is blown off the rotary platform 3, entering the subsequent tobacco pipe collecting device. For example, under the control of the automatic control system, the second air cylinder 51 extends according to the set program to drive the second air nozzle 52 to approach the empty tobacco pipe, and then releases high-pressure airflow instantaneously to blow the empty tobacco pipe away from the rotary platform 3.

[0057] In some possible implementation embodiments disclosed in the present application, referring to Figure 1 and Figure 3As shown, the tobacco separation mechanism further comprises a tobacco collection box 8 movably arranged on the side of the rotating platform 3 away from the tobacco blowing assembly 4, and the top of the tobacco collection box 8 is provided with a tobacco recovery port opposite to the first air nozzle 42; the tobacco separation mechanism further comprises a tobacco pipe collection box 9 movably arranged on the side of the rotating platform 3 away from the tobacco pipe blowing assembly 5, and the top of the tobacco pipe collection box 9 is provided with a tobacco pipe recovery port opposite to the second air nozzle 52.

[0058] In this embodiment, the tobacco collection box 8 can accurately collect the tobacco blown out of the cigarette pipe by the first air nozzle 42 through the tobacco recovery port on the top thereof opposite to the first air nozzle 42, ensuring that the tobacco can directly fall into the tobacco collection box 8 after separation, avoiding the tobacco scattered everywhere, improving the efficiency and integrity of tobacco collection, and facilitating subsequent unified processing, recycling or reuse of the tobacco. When the tobacco pipe recovery port on the top of the tobacco pipe collection box 9 is opposite to the second air nozzle 52, the empty tobacco pipe can accurately fall into the tobacco pipe collection box 9 when the second air nozzle 52 blows the empty tobacco pipe off the rotating platform 3, so that the empty tobacco pipe is orderly collected, facilitating centralized management of the empty tobacco pipe, such as recycling and reprocessing or unified disposal, which is conducive to keeping the working environment clean and orderly.

[0059] When the tobacco separation device comprises a support frame, the tobacco collection box 8 is arranged in the support frame on the side of the rotating platform 3 away from the tobacco blowing assembly 4. In this way, the internal space of the support frame is reasonably utilized, avoiding mutual interference between components during tobacco separation and collection, and facilitating the collection of tobacco.

[0060] Specifically, the first guide rail is arranged in the support frame relative to the position of the tobacco collection box 8, and the tobacco collection box 8 is slidingly arranged on the first guide rail. In actual application scenarios, the operator can manually push the tobacco collection box 8 to move along the first guide rail to adapt to different working scenarios and equipment layouts. For example, when the tobacco separation device needs to be maintained or the tobacco in the tobacco collection box 8 needs to be taken out, the tobacco collection box 8 can be easily slid out, facilitating the operator to overhaul and clean the inside of the equipment and recycle the tobacco. In addition, in order to further improve the convenience of operation, a handle for easy gripping can be installed on the tobacco collection box 8, and the surface of the handle is designed to be anti-slip to increase the friction, so that the operator can more easily and stably push the tobacco collection box 8.

[0061] When the tobacco separation device comprises a support frame, the tobacco pipe collection box 9 is arranged in the support frame on the side of the rotating platform 3 away from the tobacco pipe blowing assembly 5. In this way, the internal space of the support frame is reasonably utilized, avoiding mutual interference between components during empty tobacco pipe collection, and facilitating the collection of empty tobacco pipes.

[0062] Specifically, the second guide rail is arranged at the position of the support frame relative to the tobacco pipe collecting box 9, and the tobacco pipe collecting box 9 is slidingly arranged on the second guide rail. In the actual application scenario, the operator can manually push the tobacco pipe collecting box 9 to move along the second guide rail to adapt to different working scenarios and equipment layouts. For example, when it is necessary to maintain the tobacco pipe separating device or take out the empty tobacco pipes in the tobacco pipe collecting box 9, the tobacco pipe collecting box 9 can be easily slid out, which facilitates the operator to overhaul and clean the inside of the equipment and recycle the empty tobacco pipes. In addition, in order to further improve the convenience of operation, a handle for easy gripping can also be installed on the tobacco pipe collecting box 9, and the surface of the handle is designed to be anti-slip to increase the friction, so that the operator can more easily and stably push the tobacco pipe collecting box 9.

[0063] In some possible implementation embodiments of the present application, referring to Figure 2 As shown in the figure, the cigarette conveying mechanism further comprises a pushing roller 10, and the wall of the conveying bin 1 is provided with a driving opening, and the pushing roller 10 is rotatably arranged at the driving opening. The pushing roller 10 is used to push the cigarettes in the conveying bin 1 to move towards the bottom of the conveying bin 1.

[0064] In this embodiment, the pushing roller 10 is rotatably arranged at the driving opening, can fully contact with the cigarettes and apply a continuous and stable pushing force, so that the cigarettes in the conveying bin 1 move in the set direction, i.e. towards the bottom of the conveying bin 1, thereby ensuring that the cigarettes maintain a certain speed and posture during the conveying process, avoiding the situation that the cigarettes stop, skew or block, and ensuring the smoothness and continuity of the cigarette conveying, which helps to improve the stability and reliability of the entire cigarette production process.

[0065] In the embodiment of the present application, referring to Figure 2 As shown in the figure, the pushing roller 10 rotates in the counterclockwise direction.

[0066] In the embodiment of the present application, the push roller 10 and the conveying roller 2 share one driving motor, which serves as a power source to provide operating power for the entire conveying process. In actual application scenarios, the push roller 10 is set as a driving roller, which is directly connected to the output shaft of the driving motor through a shaft coupling or other suitable transmission components. When the driving motor is started and operates, the rotating power output by the motor is directly transmitted to the push roller 10, driving the push roller 10 to rotate at a set speed and direction. The conveying roller 2 is a driven roller, which is connected to the push roller 10 through mechanical transmission such as belt transmission, chain transmission or gear transmission. Taking belt transmission as an example, a matched pulley is installed at the shaft end of the push roller 10 and the conveying roller 2, and a belt is wrapped around the two pulleys. When the driving roller (push roller 10) is driven by the driving motor to rotate, the belt moves, thereby driving the driven roller (conveying roller 2) to rotate synchronously. In this way, the same driving motor is used to drive the push roller 10 as the driving power output, and the conveying roller 2 works cooperatively to complete the operation process of pushing the cigarettes in the conveying bin 1 and feeding them out of the discharge port, effectively simplifying the driving structure and reducing the equipment cost, while ensuring the coordination and stability of the cigarette conveying action.

[0067] Specifically, in actual application scenarios, when the cigarettes are located in the conveying bin 1, the push roller 10 starts to rotate. Since the push roller 10 is in contact with the cigarettes, the friction generated by the rotation of the push roller 10 will act on the cigarettes. Driven by this friction, the cigarettes will move towards the bottom of the conveying bin 1.

[0068] In some possible implemented embodiments disclosed in the present application, referring to FIG. 1, the cigarette conveying mechanism further includes a counting sensor 11, and the detection end of the counting sensor 11 is arranged towards the falling path of the cigarettes. Figure 2

[0069] In this embodiment, the counting sensor 11 can accurately count the number of falling cigarettes, so that the production manager can grasp the output of the cigarettes on the production line in real time, and facilitate the development of a reasonable production plan. On the other hand, the counting sensor 11 can serve as a starting signal for the clamp 7, ensuring that the clamp 7 accurately acts at the right time, avoiding the problems of early or late starting of the clamp 7 caused by manual operation or inaccurate time control, and improving the accuracy and reliability of the tobacco separation operation.

[0070] In the embodiment, the counting sensor 11 can be a photoelectric sensor.

[0071] In the embodiment, when the tobacco separation device includes a support frame, and a bearing plate is horizontally arranged at the top of the support frame, the counting sensor 11 is fixed on the bearing plate.

[0072] ​Specifically, the detection end of the counting sensor 11 (for example, the emission and receiving end of the photoelectric sensor) is opposite to the falling track of the cigarette during the conveying process. That is, when the cigarette falls downward from the groove of the conveying roller 2, it will pass through the area corresponding to the detection end of the counting sensor 11. When the cigarette passes through the area covered by the detection end of the counting sensor 11, it will cause a change in the physical quantity inside the counting sensor 11, for example, the photoelectric sensor will cause a change in the light intensity received by the receiving end due to the blocking of the light by the cigarette. Thus, the recognition of the cigarette is realized.

[0073] In some possible implementation examples disclosed in the present application, referring to Figure 2 As shown in the figure, the cigarette conveying mechanism further includes a limiting block 12, which is arranged in the conveying bin 1 and is used to limit the cigarette in the length direction of the cigarette.

[0074] In this embodiment, by arranging the limiting block 12, the cigarette can be limited in the length direction, so that the cigarette is arranged in a specific direction and position, avoiding the situation that the cigarettes are inclined and randomly stacked in the conveying bin 1, and ensuring that the cigarettes are arranged in order, which is beneficial to the smooth conveying of the cigarettes.

[0075] In the present embodiment, referring to Figure 2 As shown in the figure, the conveying bin 1 is generally in a funnel shape, and the limiting block 12 is generally in an inverted triangular shape. In actual application scenarios, the tip of the inverted triangular limiting block 12 faces downward, and the two inclined sides thereof are attached to the inner wall of the conveying bin 1, and are installed and fixed by clamping.

[0076] It should be noted that the limiting block 12 can be arranged in one, two or three, and the specific number can be flexibly determined according to the size of the cigarette conveying bin 1, the specification of the cigarette and the actual production demand. When the conveying bin 1 is small, the specifications of the cigarettes are uniform, and the conveying amount is not large, a single limiting block 12 can effectively limit the cigarette in the length direction, ensuring the basic orderliness of the cigarette conveying. If the size of the conveying bin 1 is large, or multiple specifications of cigarettes need to be conveyed at the same time, two limiting blocks 12 are symmetrically distributed on the inner walls of the opposite sides of the conveying bin 1, which can expand the limiting range and more comprehensively constrain the cigarettes in different positions, so as to ensure that all types of cigarettes can maintain a stable posture during the conveying process.

[0077] In some possible implementation examples disclosed in the present application, referring to Figure 4 As shown in the figure, the clamp 7 includes a first clamping body 71 and a second clamping body 72, and a force sensor 73 is arranged on the plane position where the first clamping body 71 and the second clamping body 72 are in contact, and the force sensor 73 is used to monitor the clamping force.

[0078] In this embodiment, by arranging the force sensor 73, the clamping force of the clamp 7 can be accurately monitored in real time, so that the clamp 7 can control the clamping force within a range that can just fix the cigarette without causing damage.

[0079] The first clamp body 71 and the second clamp body 72 are the main components for realizing the clamping function. In actual working scenarios, the first clamp body 71 and the second clamp body 72 cooperate with each other to clamp the object (for example, a cigarette) to be fixed through the action of approaching or closing, so as to ensure the stability of the object during subsequent operations (such as tobacco separation), prevent the object from moving or shaking, and ensure that the relevant operations can be smoothly and accurately performed.

[0080] Specifically, the clamp 7 further comprises a driving cylinder having two driving ends connected with the first clamp body 71 and the second clamp body 72 respectively, for pushing the first clamp body 71 and the second clamp body 72 to move. In actual application scenarios, when the counting sensor 11 is triggered, the driving cylinder responds quickly, the two driving ends are synchronously shortened, and the first clamp body 71 and the second clamp body 72 start to approach each other. In this process, the force sensor 73 monitors the clamping force generated between the two in real time and feeds back the data to the control system. The control system dynamically adjusts the driving force of the driving cylinder according to the preset clamping force threshold. When the clamping force approaches the set value, the control system accurately adjusts the output of the driving cylinder, so that the first clamp body 71 and the second clamp body 72 clamp the cigarette with smooth and accurate force.

[0081] The first clamp body 71 and the second clamp body 72 each comprise a clamping part and a flat part, and the clamping part can be an arc structure or a semicircular structure, and the flat part can be a planar structure.

[0082] Specifically, in actual application scenarios, the arc structure or semicircular structure of the clamping part can perfectly fit the cylindrical shape of the cigarette. When the two driving ends of the driving cylinder push the first clamp body 71 and the second clamp body 72 to approach each other, the clamping part can wrap around the side of the cigarette, providing all-round support and fixation for the cigarette, not only increasing the contact area between the first clamp body 71 and the second clamp body 72 and the cigarette, so that the clamping force can be evenly distributed on the surface of the cigarette, effectively avoiding the problem of cigarette deformation caused by excessive local pressure, but also enhancing the friction force of the first clamp body 71 and the second clamp body 72 on the cigarette, further improving the stability of clamping. The planar structure of the flat part provides a flat and stable installation position for the force sensor 73. The force sensor 73 can be accurately installed on the flat part plane where the first clamp body 71 and the second clamp body 72 contact, so that the clamping force between the first clamp body 71 and the second clamp body 72 can be accurately monitored during the clamping process.

[0083] In some possible implementation embodiments disclosed in the present application, a position sensor is arranged in each of the cut tobacco collecting bin 8 and the tobacco pipe collecting bin 9, and the position sensor is used to monitor the material height position.

[0084] In this embodiment, the position sensor can monitor the height position of the material in the collecting bin in real time and feed back the data to the control system. When the material reaches the preset height, the control system can automatically trigger the corresponding operation, such as stopping feeding or reminding the operator to handle, thereby reducing manual intervention and improving the automation degree and continuity of production.

[0085] It should be noted that when the cut tobacco separating device includes a support frame, an electric control cabinet is further arranged in the support frame, and the electric control cabinet is a carrier of the control system of the entire cut tobacco separating device and integrates a plurality of key electrical elements and control modules, thereby providing a solid guarantee for stable operation and accurate control of the device. Specifically, the control system can be a programmable logic controller (PLC) which is installed inside the electric control cabinet. The PLC accurately controls the operation of each component of the cut tobacco separating device through a pre-written program. For example, for the cigarette conveying mechanism, the PLC controls the rotation speed and start-stop of the conveying roller 2 and the pushing roller 10 according to the cigarette quantity information fed back by the counting sensor 11, so as to ensure that the cigarettes can be conveyed to the clamp 7 position in a set rhythm and sequence. Meanwhile, the PLC also receives the material height position signal of the cut tobacco collecting bin 8 and the tobacco pipe collecting bin 9 transmitted by the position sensor, and timely reminds the operator to handle when the material reaches the preset height. As for the clamp 7 control, the PLC accurately adjusts the action of the driving cylinder according to the clamping force data monitored by the force sensor 73, so that the clamp 7 can clamp the cigarettes with just the right amount of force, which not only ensures the stability of the cigarettes in the cut tobacco separating process, but also prevents damage to the cigarettes caused by excessive clamping force. In addition, the electric control cabinet is also equipped with relays, contactors and other execution elements which realize on-off control of the power equipment such as motors and cylinders under the instruction of the PLC, so as to ensure that each component can accurately act according to the requirements of the control system.

[0086] In some possible implementation embodiments disclosed in the present application, the cut tobacco separating device further includes a warning light which is arranged at the top of the support frame.

[0087] Specifically, when the cut tobacco separating device is normally running, the warning light continuously emits soft green light. Once the cut tobacco separating device is abnormal, the warning light will quickly switch state. If it is detected that the material height in the cut tobacco collecting bin 8 or the tobacco pipe collecting bin 9 reaches a dangerous value, the position sensor will transmit a signal to the control system, and then trigger the warning light to emit flickering yellow light, thereby reminding the operator to handle in time.

[0088] In some possible implementation embodiments disclosed in the present application, referring to Figure 1As shown, an indication sign 13 is pasted on the outer wall of the conveying bin 1, which is used to guide the placement direction of the cigarette in the conveying bin 1.

[0089] In this embodiment, by setting the indication sign 13 to guide the cigarette to enter the conveying bin 1 in the correct direction, the cigarette can be more smoothly conveyed, and the jamming phenomenon caused by the wrong direction is reduced. That is, the cigarette can fall into the rotating platform 3 in the correct order, so that the clamp 7 can quickly align the cigarette tube for clamping operation, without the need to spend extra time to adjust the direction and position of the cigarette. Thus, the time for the clamp 7 to clamp the cigarette tube is shortened, the production rhythm is accelerated, the number of cigarettes that can be processed per unit time is increased, and the overall production efficiency is improved.

[0090] Among them, the indication sign 13 can be a sticker marked with a cigarette pattern, which is firmly pasted on the outer wall of the conveying bin 1 by means of glue, etc., and the position is usually in a place that is easy for the operator to observe, so as to play its guiding role.

[0091] Specifically, when the cigarette enters the conveying bin 1, it needs to be placed in a certain direction and posture, so as to ensure smooth progress in the conveying process and subsequent production processes. The indication sign 13 provides clear guidance for the placement of the cigarette through its specific pattern. For example, the indication sign 13 has a specific shape profile, which suggests that the cigarette is arranged into the conveying bin 1 in a certain specific way.

[0092] It is easy for those skilled in the art to understand that the above advantageous modes can be freely combined and superimposed without conflict.

[0093] The above is only a preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, which should be considered as the protection scope of the present application.
