Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco production equipment technology, and more specifically, to a tobacco shred flow control system. Background Technology
[0002] Expanded tobacco processing is an important tobacco processing technology in the modern cigarette industry. It is widely used because it meets the requirements of modern cigarette manufacturers to improve the intrinsic quality of tobacco, reduce costs, and enhance safety.
[0003] At present, the more mature and popular tobacco expansion technologies can be divided into dry ice expansion technology, Freon expansion technology and nitrogen expansion technology according to the different expansion media. Among them, the tobacco expansion technology with dry ice as the expansion medium is the most widely used.
[0004] The process principle of the dry ice expanded tobacco production line is as follows: First, the tobacco is soaked in liquid carbon dioxide. The low temperature causes dry ice to form inside and on the surface of the tobacco. The tobacco is then passed through a hot air pipe, and the dry ice is rapidly sublimated using heating technology to obtain expanded tobacco. This process involves multiple production links such as a vibrating cabinet, a feeding conveyor belt, a hot air pipe, and a discharging conveyor belt.
[0005] Since the output flow rate of tobacco shreds has a significant impact on the quality of subsequent production processes, the main control objective of this process is to keep the tobacco shred flow rate stable around the expected value. However, due to the unstable feeding factor in this production line, the current on-site control effect cannot meet the process's requirement for stable tobacco shred flow rate.
[0006] Therefore, there is an urgent need to provide a tobacco shred feed flow control system to solve the above problems to some extent. Utility Model Content
[0007] The purpose of this application is to provide a tobacco shred feeding flow control system to address the current problem of difficulty in controlling the flow accuracy during tobacco shred conveying, which leads to deviations in the output weight.

[0011] Specifically, the material distribution drive assembly includes a drive component, a drive wheel, and a driven wheel; the bracket is provided with a mounting base, the drive component is disposed on the mounting base, the output end of the drive component is connected to the drive wheel, the drive wheel is drivenly connected to the driven wheel, and the driven wheel is sleeved on the guide section and fixedly connected to the guide section.
[0012] Specifically, the metering unit includes a transfer hopper and a measuring hopper; the transfer hopper is located above the measuring hopper, and the outlet of the transfer hopper is provided with a first sealing component, which can open or close the outlet of the transfer hopper; the outlet of the measuring hopper is provided with a second sealing component, which can open or close the outlet of the measuring hopper; the outlet of the material distribution section is connected to the inlet of the transfer hopper to convey tobacco shreds.
[0013] Furthermore, the transfer hopper includes a material carrier box, the first sealing assembly includes a first cover and a first cylinder, one end of the first cover is rotatably connected to the material carrier box, and the telescopic end of the first cylinder is rotatably connected to the other end of the first cover; the measuring hopper includes a measuring box and a meter, the meter is disposed at the outlet position of the measuring box, the second sealing assembly includes a second cover and a second cylinder, one end of the second cover is rotatably connected to the measuring box, and the telescopic end of the second cylinder is rotatably connected to the other end of the second cover.
[0014] The tobacco feeding flow control system provided in this application also includes a positioning cover, which is connected to the bracket, and multiple metering units are evenly distributed at equal intervals along the circumference of the positioning cover.
[0015] Specifically, the tobacco feeding flow control system provided in this application also includes a material guide, which is disposed between two adjacent material carriers and has an inverted V-shaped structure.
[0016] Furthermore, the discharge conveying mechanism includes a conveyor belt and a weighing component. One end of the conveyor belt is located below the outlet of the guide hopper, and the weighing component is disposed inside the conveyor belt for measuring the weight of the material falling on the conveyor belt.
[0017] Furthermore, the tobacco feeding flow control system provided in this application also includes an electric airlock, which is disposed at the discharge end of the discharge conveying mechanism.
[0018] Compared with existing technologies, the tobacco shred flow control system provided in this application has the following advantages: The tobacco feeding flow control system provided in this application includes a vibrating cabinet, a feeding mechanism, a metering mechanism, and a discharge conveying mechanism. The feeding mechanism includes a feeding drive component and a feeding pipe. The feeding pipe includes a guide section, a connecting section, and a feeding segment. One end of the guide section is connected to the discharge port of the vibrating cabinet, and the other end is connected to one end of the connecting section. The connecting section and the guide section are set at an angle. The other end of the connecting section is connected to one end of the feeding segment. The feeding drive component is connected to the guide section and drives the guide section to rotate relative to the vibrating cabinet. The metering mechanism includes multiple metering units and a feeding hopper. The multiple metering units are evenly distributed along the circumference of the vibrating cabinet. The outlet of the feeding segment can cover the inlet of the metering unit. The feeding hopper is located below the outlet of the metering unit. The discharge conveying mechanism is located below the outlet of the feeding hopper.
[0019] Analysis shows that the vibrating cabinet can hold the tobacco shreds, and the vibration of the cabinet keeps the shreds loose, preventing them from tangling and causing blockages at the discharge outlet. The distribution pipe connected to the discharge outlet of the vibrating cabinet (which includes a guide section, a connecting section, and a distribution section) transports the tobacco shreds to the distribution section. Because the connecting section and the guide section are angled, the distribution pipe in this application is approximately Z-shaped.
[0020] It is understandable that, since the dispensing pipe in this application can rotate relative to the vibrating cabinet, when the Z-shaped dispensing pipe rotates, the dispensing section can rotate around the guiding section as the center of rotation, forming a ring-shaped rotating area. Multiple metering units are distributed within this area, allowing the tobacco shreds to fall into the metering units during the rotation of the dispensing pipe.
[0021] In this application, the metering unit is equipped with a weighing sensor or pressure sensor to weigh the tobacco shreds falling into the metering unit. Due to the special material form of tobacco shreds, it is impossible to guarantee a consistent output amount of tobacco shreds each time even with the same feeding time, and the amount of tobacco shreds fed each time will generally have a deviation. Therefore, this application can achieve the weighing of tobacco shreds entering the metering unit by setting multiple metering units. After weighing, the weight can be transmitted to the system controller. The operator can obtain the weight in each metering unit through the controller. Then, the operator calculates and opens the outlet of the metering unit whose total weight matches the predetermined output weight, allowing the tobacco shreds in the corresponding metering unit to fall into the guide hopper. Through the guide hopper, the tobacco shreds are transported to the discharge conveyor mechanism, achieving a state where the output weight is consistent each time or the deviation from the predetermined output is controllable, ensuring discharge accuracy and avoiding the problem of large deviations in discharge accuracy affecting subsequent production processes.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0029] like Figure 1As shown, the tobacco feeding flow control system provided in this application includes a vibrating cabinet 2, a feeding mechanism, a metering mechanism 4, and a discharge conveying mechanism. The feeding mechanism includes a feeding drive assembly and a feeding pipe 3. The feeding pipe 3 includes a guide section 301, a connecting section 302, and a feeding section 303. One end of the guide section 301 is connected to the discharge port of the vibrating cabinet 2, and the other end is connected to one end of the connecting section 302. The connecting section 302 and the guide section 301 are set at an angle. The other end of the connecting section 302 is connected to one end of the feeding section 303. The feeding drive assembly is connected to the guide section 301 and drives the guide section 301 to rotate relative to the vibrating cabinet 2. The metering mechanism 4 includes multiple metering units and a feeding hopper 406. The multiple metering units are evenly distributed along the circumference of the vibrating cabinet 2. The outlet of the feeding section 303 can cover the inlet of the metering unit. The feeding hopper 406 is located below the outlet of the metering unit. The discharge conveying mechanism is located below the outlet of the feeding hopper 406.
[0030] Compared with existing technologies, the tobacco shred flow control system provided in this application has the following advantages: The tobacco feeding flow control system provided in this application can hold tobacco shreds through the vibrating cabinet 2, and the vibration of the vibrating cabinet 2 can always keep the tobacco shreds loose, avoiding tangling and causing discharge blockage. The distribution pipe 3 connected to the discharge port of the vibrating cabinet 2, and the distribution pipe 3 in this application includes a guide section 301, a connecting section 302 and a distribution section 303, the guide section 301 is connected to the discharge port of the vibrating cabinet 2, and can convey tobacco shreds to the distribution section 303. Since the connecting section 302 is set at an angle to the guide section 301, the distribution pipe 3 in this application is generally approximately Z-shaped.
[0031] It is understandable that, since the dispensing pipe 3 in this application can rotate relative to the vibrating cabinet 2, when the Z-shaped dispensing pipe 3 rotates, the dispensing section 303 can rotate around the guiding section 301 as the center of rotation, forming a ring-shaped rotating area. Multiple metering units are distributed in this area, and the tobacco shreds can fall into the metering units during the rotation of the dispensing pipe 3.
[0032] In this application, the metering unit is equipped with a weighing sensor or a pressure sensor to weigh the tobacco shreds falling into the metering unit. Due to the special material form of tobacco shreds, it is impossible to guarantee a consistent output amount of tobacco shreds each time even with the same feeding time, and the amount of tobacco shreds fed each time will generally have a deviation. Therefore, this application can achieve the weighing of tobacco shreds entering the metering unit by setting multiple metering units. After weighing, the weight can be transmitted to the system controller. The operator can obtain the weight in each metering unit through the controller. Then, the operator calculates and opens the outlet of the metering unit whose total weight matches the predetermined output weight, allowing the tobacco shreds in the corresponding metering unit to fall into the guide hopper 406. The guide hopper 406 is then transported to the discharge conveyor mechanism, achieving a state where the output weight is consistent each time or the deviation from the predetermined output is controllable, ensuring discharge accuracy and avoiding the problem of large deviations in discharge accuracy affecting subsequent production processes.
[0033] In this embodiment, the outlet of the metering unit in this application is equipped with a valve. When the valve is open, the tobacco shreds in the metering unit can fall naturally, and when closed, it can hold the tobacco shreds. The valve in this application is a gate-type discharge valve commonly used in the prior art, which uses a gate to achieve the closing and opening of the outlet, and will not be described in detail here.
[0034] It should be noted that the controller in this application can be further connected to multiple displays and multiple control buttons. Each control button controls one metering unit, and each display shows the weighing result of the corresponding metering unit. When the weight of the tobacco falling into the metering unit stabilizes, it is displayed on the display. The operator can calculate and accumulate the values by observing the values on the display, select several metering units whose sum is the same as the predetermined output value, and open the outlet of the corresponding metering unit to achieve accurate material discharge.
[0035] If the number of metering units in this application is 10, numbered 1-10, and the discharge time of the dispensing pipe 3 is the same each time, the discharge amount is set to 500g, and the total discharge amount is 1000g, then if the output amount of the dispensing pipe 3 is accurate, then any two metering units can output material. However, due to the special nature of tobacco, the discharge amount output by the dispensing pipe 3 each time has a deviation, such as 490g, 495g, 502g, 510g, etc. Therefore, the accuracy of the tobacco received in each metering unit can be displayed on the screen. Then, the operator can find two screen readings that reach or are close to 1000g by adding the readings, such as No. 1 weighing 496g and No. 2 weighing 504g, and then the No. 1 and No. 2 metering units can be unloaded. If two metering units do not accurately reach 1000g during the calculation process, the acceptable deviation is no more than 1g, that is, 999g or 1001g is acceptable. Once the two corresponding metering units are determined, press the control button below the corresponding display screen to open the gate at the outlet of the metering unit and complete the unloading.
[0036] It should be noted that the output process of the distribution pipe 3 in this application is intermittent discharge, that is, the distribution pipe 3 starts to output when the outlet of the distribution pipe 3 corresponds to the inlet of the metering unit. This can be achieved by adding a valve to the outlet of the distribution section 303 or a valve to the outlet of the vibrating cabinet 2. The means of controlling the opening and closing of the valve and ensuring that the opening time is consistent are all commonly used technical means at present, and will not be described in detail here.
[0037] Optionally, such as Figure 1 Combination Figure 2 As shown, the vibrating cabinet 2 in this application includes a storage bin 201, a vibration motor 202, and a support 1; the support 1 forms a support space, the storage bin 201 is disposed in the support space, and the storage bin 201 is connected to the support 1; the vibration motor 202 is disposed on the storage bin 201 and is used to vibrate the storage bin 201.
[0038] The storage bin 201 is used to hold tobacco shreds. To prevent the tobacco shreds from getting tangled and knotted inside the storage bin 201, a vibration motor 202 is installed outside the storage bin 201. This allows the storage bin 201 to be in a vibrating state, which reduces the risk of tobacco shreds getting tangled and knotted to a certain extent and ensures that the tobacco shreds are output smoothly.
[0039] It is understood that the support frame 1 in this application is supported on the ground and forms a support space for supporting the storage bin 201. The storage bin 201 can be welded to the support frame 1 or connected by fasteners such as bolts. Of course, in addition to the four columns shown in the figure, the support frame 1 can be further connected with crossbeams between the columns to form the aforementioned support space. The storage bin 201 sits on the crossbeams, achieving a stable connection with the support frame 1.
[0040] The bottom of the storage bin 201 in this application has a funnel-shaped structure, which allows the tobacco to smoothly gather and flow into the distribution pipe 3.
[0041] Optionally, such as Figure 1 As shown, the tobacco feeding flow control system provided in this application also includes a buffer 7, which is disposed between the support 1 and the storage bin 201.
[0042] The buffer 7 in this application can be a strip structure made of rubber material, extending along the upright direction of the support 1 and set between the storage bin 201 and the support 1. Since the storage bin 201 will vibrate due to the drive of the vibration motor 202, the buffer 7 in this application can buffer the vibration of the storage bin 201 to a certain extent, and can also isolate the vibration of the storage bin 201 to a certain extent, so as to avoid the vibration being transmitted to the support 1 and causing the support 1 to move.
[0043] Optionally, such as Figure 1 Combination Figure 3 As shown, the material distribution drive assembly in this application includes a drive component 304, a drive wheel 307, and a driven wheel 305; a mounting base 306 is provided on the bracket 1, the drive component 304 is mounted on the mounting base 306, the output end of the drive component 304 is connected to the drive wheel 307, the drive wheel 307 is connected to the driven wheel 305 in a transmission connection, and the driven wheel 305 is sleeved on the guide section 301 and fixedly connected to the guide section 301.
[0044] In this application, the driving component 304 is a motor, and both the driving wheel 307 and the driven wheel 305 are gears. The output shaft of the motor is connected to the driving wheel 307, so that the driving wheel 307 can be driven to rotate when started. Since the driving wheel 307 and the driven wheel 305 are meshed, the driven wheel 305 can be driven to rotate.
[0045] It is understood that in this application, the driven wheel 305 is fixedly connected to the guide section 301, so that when the driven wheel 305 rotates, it can drive the guide section 301 to rotate, thereby realizing the rotation of the entire material distribution tube 3. Since the driving wheel 307 and the driven wheel 305 in this application are gears, the material distribution tube 3 can rotate the same distance each time. Since the metering units in this application are evenly distributed along the circumference of the positioning cover 405, there is a spacing between adjacent metering units. Through the cooperation of the gears, the material distribution tube 3 can rotate at equal intervals, thereby ensuring that it is aligned with the metering unit when stopped and crosses the spacing of the metering unit when rotating.
[0046] Optionally, such as Figure 4 As shown, the metering unit in this application includes a transfer hopper and a measuring hopper; the transfer hopper is located above the measuring hopper, and the outlet of the transfer hopper is provided with a first sealing component, which can open or close the outlet of the transfer hopper; the outlet of the measuring hopper is provided with a second sealing component, which can open or close the outlet of the measuring hopper; the outlet of the material distribution section 303 is connected to the inlet of the transfer hopper to convey tobacco shreds.
[0047] Since the tobacco shreds will fall under gravity after being discharged from the feed pipe 3, the impact on the measuring device in the measuring hopper can be reduced by setting a transfer hopper above the measuring hopper, thus ensuring the accuracy of the measured weight.
[0048] Therefore, in this application, the outlet of the transfer hopper can partially enter the measuring hopper, but preferably, the outlet of the transfer hopper is flush with the inlet plane of the measuring hopper, so as to minimize the impact of the falling tobacco on the meter and ensure measurement accuracy.
[0049] Accordingly, in this application, both the first sealing assembly and the second sealing assembly can adopt a gate valve or other discharge valve structure, so that the tobacco can be conveyed by opening or closing the first sealing assembly and the second sealing assembly.
[0050] Optionally, such as Figure 4 As shown, the transfer hopper in this application includes a material container 401, the first sealing assembly includes a first cover 402 and a first cylinder, one end of the first cover 402 is rotatably connected to the material container 401, and the telescopic end of the first cylinder is rotatably connected to the other end of the first cover 402; the measuring hopper includes a measuring box 403 and a meter, the meter is set at the outlet position of the measuring box 403, and the second sealing assembly includes a second cover 404 and a second cylinder, one end of the second cover 404 is rotatably connected to the measuring box 403, and the telescopic end of the second cylinder is rotatably connected to the other end of the second cover 404.
[0051] In this application, the first cylinder and the second cylinder (both shown in the figure) can drive the first cover 402 and the second cover 404 to open or close, thereby enabling the actions of discharging and storing materials.
[0052] In actual operation, there are two operating modes. In one mode, the material distribution pipe 3 rotates to reach the metering unit and then starts feeding. During the rotation, the feeding stops. In this mode, the material loading box 401 ensures the continuity of the operation to a certain extent. That is, during operation, the rotation of the material distribution pipe 3 in the circumferential direction will gradually fill the material loading box 401. After all the material loading boxes 401 are filled, the outlets of all the material loading boxes 401 can be opened, allowing the first batch of material to enter the corresponding measuring box 403 for weighing. The operator calculates and opens the outlet of the measuring box 403 that meets the total weight standard to complete the feeding action. During this process, the material distribution pipe 3 rotates again to fill the material loading box 401 until it is full. At this time, the operator can open the outlet of the material loading box 401 corresponding to the empty measuring box 403, so that the measuring box 403 is filled again. Then, the operator continues to select the corresponding measuring box 403 that meets the weight standard and repeats the above actions, thus achieving precise control of the weight of the tobacco feeding.
[0053] It should be noted that a pressure sensor can also be installed in the material box 401 during this process. When the pressure sensor has a pressure signal, the controller can control the valve at the outlet of the distribution pipe 3 to close, thereby preventing the material from overflowing from the material box 401.
[0054] Preferably, such as Figure 1 Combination Figure 4 As shown, the tobacco feeding flow control system provided in this application also includes a positioning cover 405, which is connected to the bracket 1, and multiple metering units are evenly distributed at equal intervals along the circumference of the positioning cover 405.
[0055] Another operating logic in this application is simpler, but a guide component needs to be set between two adjacent material boxes 401, and the guide component in this application has an inverted V-shaped structure.
[0056] In this method, since the gap between adjacent material boxes 401 is filled by a guide member and the guide member is arranged in an inverted V shape, the material distribution pipe 3 can continuously output tobacco shreds, that is, the outlet of the material distribution pipe 3 always outputs tobacco shreds outward during the rotation process.
[0057] Accordingly, in this embodiment, a weighing sensor is also required to be designed inside the material box 401. When the weight of the tobacco in the material box 401 reaches the predetermined weight, the first cover 402 can be opened to allow the tobacco to enter the measuring box 403 for measurement again. When the measured weights are consistent, the second cover 404 can be opened to allow the tobacco to fall and reach the discharge conveying device 5 for discharge.
[0058] Optionally, such as Figure 1 As shown, the material conveying mechanism in this application includes a conveyor belt and a weighing component. One end of the conveyor belt is located below the outlet of the guide hopper 406, and the weighing component is installed inside the conveyor belt to measure the weight of the material falling on the conveyor belt.
[0059] The discharge conveying mechanism in this application is an electronic belt scale, which can weigh the tobacco shreds falling on the discharge conveying device 5 again to further ensure the accuracy of the feeding. When there is a large deviation in the weight measured by the electronic belt scale, the tobacco shreds can be manually removed or added to ensure the quality of subsequent operations.
[0060] Preferably, such as Figure 1 As shown, the tobacco feeding flow control system provided in this application also includes an electric airlock 6, which is installed at the discharge end of the discharge conveying mechanism.
[0061] The electric airlock 6 in this application mainly includes a drive system, which includes a motor, a reducer or a coupling; an impeller; a housing, which includes a feed, a discharge and an internal sealed cavity formed in conjunction with the impeller; and a sealing assembly that enables a precise clearance design between the blade edge and the inner wall of the housing to reduce gas leakage.
[0062] When the electronic belt scale delivers the tobacco to the inlet of the electric airlock 6, the tobacco falls into the blade chamber of the electric airlock 6 by gravity. The electric airlock 6 rotates at a constant speed, so that each chamber goes through the three stages of feeding, sealing and unloading in sequence. Feeding stage: The chamber is aligned with the discharge port of the electronic belt scale, and the chamber is filled with tobacco. Sealing stage: The blade rotates to the valve body sealing area, and the precise fit between the blade and the valve body cuts off the upstream and downstream airflow channels; Unloading stage: The chamber is aligned with the downstream outlet of the electric airlock 6, and the tobacco is discharged under gravity to avoid backflow caused by negative pressure in subsequent equipment.
[0063] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0064] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
