[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figure 1 As shown, this utility model provides a tobacco processing feeding device including a feeding cylinder 4, a cleaning structure 5, a blowing structure, and a discharge structure; the feeding cylinder 4 has a discharge port at its bottom end; the cleaning structure 5 includes a rotating rod 53 disposed inside the feeding cylinder 4, the axis of the rotating rod 53 coincides with the axis of the feeding cylinder 4, and the rotating rod 53 can rotate around its own axis; at least one scraper 55 and at least one brush 56 are fixedly connected to the rotating rod 53, the scraper 55 is in contact with the inner wall of the feeding cylinder 4, and the rotating rod 5... The axis of 3 is located in the plane of scraper 55. The brush 56 includes a brush plate and several bristles. The axis of the rotating rod 53 is located in the plane of the brush plate. The bristles are located on the side of the brush plate away from the rotating rod 53 and are in contact with the inner wall of the discharge cylinder 4. The blowing structure includes several blowing heads 58 located in the discharge cylinder 4. All the blowing heads 58 are evenly distributed around the axis of the rotating rod 53. The blowing heads 58 are used to blow and sweep the inner wall of the discharge cylinder 4. The discharge structure selectively closes the discharge port.

[0030] This tobacco processing feeding device uses a rotating rod 53 in the cleaning structure 5 to drive the scraper 55 and brush 56 to rotate, automatically cleaning the dirt and dust on the inner wall of the feeding cylinder 4. Specifically, the scraper 55 removes dirt, and the brush 56 sweeps away dust. Simultaneously, a blowing structure uses several blowers 58 to blow air onto the inner wall of the feeding cylinder 4, assisting in removing residual dust and dirt. The discharge structure can selectively close the discharge port, facilitating control of material discharge and the cleaning process, ensuring smooth discharge of dirt during cleaning. Overall, the tobacco processing feeding device achieves automated cleaning of the inside of the feeding cylinder 4, replacing manual cleaning methods, significantly reducing the labor intensity of workers, improving cleaning efficiency, preventing dirt accumulation, and solving the problems of inconvenience and high labor intensity associated with manual cleaning in existing technologies.

[0031] In this embodiment, a plurality of stirring rods 11 for stirring materials are fixedly connected to the side wall of the rotating rod 53, and the stirring rods 11 extend radially along the rotating rod 53; a feed pipe 16 is inserted into the top of the discharge cylinder 4, and the material enters the discharge cylinder 4 through the feed pipe 16.

[0032] In this embodiment, tobacco is used as an example of the material.

[0033] For example, a servo motor 51 is also fixedly connected to the top of the feeding cylinder 4. The output end of the servo motor 51 is coaxially fixedly connected to the rotating rod 53. The servo motor 51 is used to drive the rotating rod 53 to rotate.

[0034] In this embodiment, mounting rods 54 are evenly distributed circumferentially on the side wall of the rotating rod 53. The sum of the number of scrapers 55 and brushes 56 is the same as the number of mounting rods 54. Each mounting rod 54 is connected to the brush plate of a brush 56 or a scraper 55.

[0035] The circumferentially distributed design of the mounting rods 54 ensures that the scraper 55 and brush 56 evenly cover the inner wall of the discharge cylinder 4 under the drive of the rotating rod 53, improving the comprehensiveness and consistency of cleaning. Each mounting rod 54 is individually connected to a scraper 55 or brush 56, which makes the cleaning force distribution reasonable, avoids cleaning dead corners, further optimizes the cleaning effect and operation stability, simplifies the installation and maintenance of the scraper 55 and brush 56, and enhances the reliability and durability of the cleaning structure 5.

[0036] For example, the blowing structure also includes a blower 52 and an annular pipe 57 disposed outside the discharge cylinder 4. The output end of the blower 52 is connected to the annular pipe 57, the annular pipe 57 is arranged around the axis of the rotating rod 53, and the blowing head 58 passes through the cylinder wall of the discharge cylinder 4 and is connected to the annular pipe 57.

[0037] Blower 52 provides uniform airflow to multiple blowers 58 through ring pipe 57, forming a ring-shaped blowing area that comprehensively sweeps the inner wall of the discharge cylinder 4. This effectively blows away residual dust and dirt after cleaning by scraper 55 and brush 56, promoting the flow of dust and dirt towards the discharge port and further improving the cleaning effect. The design of ring pipe 57 optimizes airflow distribution, avoids cleaning dead zones, enhances the auxiliary role of cleaning, and improves cleaning efficiency and automation. At the same time, blowers 58 penetrate the cylinder wall and act directly on the inner wall, working in conjunction with scraper 55 and brush 56 to effectively blow away fine dust and prevent dirt from re-adhering.

[0038] In this embodiment, the discharge structure includes a U-shaped frame 12 and a baffle 15. The U-shaped frame 12 is fixed to the bottom end of the discharge cylinder 4, and a limiting groove is formed on the inner side wall of the U-shaped frame 12. The edge of the baffle 15 is slidably engaged with the limiting groove. The baffle 15 can move relative to the U-shaped frame 12 between a blocking position and a clearance position. When the baffle 15 is in the blocking position, the baffle 15 closes the discharge port. When the baffle 15 is in the clearance position, the baffle 15 opens the discharge port.

[0039] The sliding engagement between the U-shaped frame 12 and the baffle 15 ensures reliable sealing and opening of the discharge port, facilitating control of material feeding and the discharge of cleaning contaminants. The structure is simple and easy to operate. The baffle 15 prevents material leakage when in the blocking position and allows material to discharge smoothly when in the avoidance position, facilitating the removal of contaminants during cleaning and improving operational flexibility and control precision. Simultaneously, the sliding engagement between the limiting groove of the U-shaped frame 12 and the baffle 15 ensures the stability and reliability of the baffle 15 during movement, achieving precise opening and closing of the discharge port and ensuring the stability of the baffle 15's movement, thus improving operational safety and convenience.

[0040] Furthermore, the tobacco processing and feeding device also includes an electric push rod 14, which is fixedly connected to the side of the baffle 15 away from the U-shaped frame 12, and is used to drive the baffle 15 to move relative to the U-shaped frame 12. Specifically, a support plate 13 is also fixedly connected to the bottom end of the feeding cylinder 4, and the electric push rod 14 is movably connected to the support plate 13.

[0041] The movement of the baffle 15 is automatically controlled by the electric push rod 14, which improves the accuracy and efficiency of the opening and closing of the discharge port, reduces manual intervention, and lowers the difficulty and labor intensity of operation. It is particularly suitable for continuous production environments, improving the automation level and production efficiency of the tobacco shredding feeding device. At the same time, the electric push rod 14 provides a stable driving force to ensure the accurate positioning of the baffle 15.

[0042] In this embodiment, the tobacco processing feeding device further includes a humidity sensor 9 and a heating plate 10. The humidity sensor 9 is used to monitor the humidity inside the feeding cylinder 4, and the heating plate 10 is embedded in the cylinder wall of the feeding cylinder 4 to reduce the humidity inside the feeding cylinder 4. Specifically, the humidity sensor 9 is a laser humidity sensor, which is inserted into the top of the feeding cylinder 4.

[0043] In this embodiment, the tobacco processing and feeding device also includes a controller, which is communicatively connected to the humidity sensor 9 and the heating plate 10 respectively. The controller can control the opening and closing of the heating plate 10 according to the humidity information fed back by the humidity sensor 9.

[0044] Humidity sensor 9 monitors the humidity of the material inside the feeding cylinder 4 in real time and compares it with a set benchmark value to achieve automatic humidity control. When the humidity is too high, the controller activates the heating plate 10 to heat and dehumidify, while the rotating rod 53 drives the stirring rod 11 to stir the material, ensuring uniform heating. Once the humidity of the material is lower than the benchmark value, the controller issues a command to stop the heating plate 10 and the servo motor 51 from rotating, thus stopping the heating of the material. This avoids the problem of excessively moist material sticking to the wall of the feeding cylinder 4 during subsequent screening, improves screening efficiency and product quality, reduces malfunctions of the tobacco shredding feeding device, and enhances the overall performance and reliability.

[0045] like Figures 1 to 5 As shown, this utility model also provides a tobacco shredding vibrating screener. The tobacco shredding discharge device includes a base 1, a screening box 7, and the aforementioned tobacco shredding discharge device. The tobacco shredding discharge device is fixedly connected to the base 1, and the screening box 7 is elastically connected to the base 1. The screening box 7 is used to screen the material discharged from the tobacco shredding discharge device.

[0046] This tobacco processing vibrating screen integrates an automatic cleaning and humidity control tobacco feeding device into the vibrating screen, realizing complete automation of the entire process from feeding, cleaning to screening. The cleaning and humidity management functions of the tobacco feeding device ensure the appropriate state of the material before screening, reducing maintenance time. Combined with the design of the screening box 7 being elastically connected to the base 1, it ensures the efficiency of vibrating screening and reduces clogging or adhesion problems during the screening process. Overall, it improves the use effect and production efficiency of the tobacco processing vibrating screen, solves the problems of inconvenience of manual cleaning and screening in the existing technology, optimizes the tobacco processing process, and reduces manual intervention.

[0047] In this embodiment, the feeding cylinder 4 is fixed to the top of the base 1 by two fixing plates 2; the tobacco shredding vibrating screen also includes elastic elements 6, the number of elastic elements 6 is the same as the number of corners at the bottom of the screening box 7, and each corner at the bottom of the screening box 7 is elastically connected to the base 1 by an elastic element 6.

[0048] The elastic element 6 provides stable elastic support at each corner of the bottom of the screening box 7, so that the screening box 7 remains balanced and stable during vibration, which enhances the vibration freedom of the screening box 7, enhances the uniformity and consistency of the vibration screening effect, and reduces energy loss. This design reduces the impact of vibration on the base 1, reduces equipment wear, improves screening efficiency and service life, and improves screening accuracy.

[0049] Furthermore, the elastic element 6 extends and retracts along its own length, and the length direction of the elastic element 6 is set at an angle to the vertical direction. Specifically, the elastic element 6 is a telescopic spring.

[0050] By setting the elastic element 6 at an angle to the vertical direction, the transmission direction and force distribution of vibration are optimized, enabling the screening box 7 to generate more effective three-dimensional vibration. This improves the uniform distribution and movement of materials on the screen plate 8, increases screening accuracy and efficiency, ensures that materials are fully dispersed and screened on the screen plate 8, reduces screen hole clogging, and guarantees screening capacity. The inclined elastic element 6 can also absorb some vibration energy, further optimizing the performance of the vibrating screen and ensuring that the materials in the screening box 7 can move along the pre-planned trajectory.

[0051] In this embodiment, each corner of the bottom of the screening box 7 is fixedly connected to a connecting block 73, the top of the base 1 is fixedly connected to a support frame 3, and the two ends of the elastic member 6 are respectively connected to the connecting block 73 and the support frame 3.

[0052] In this embodiment, the screening box 7 has an upward-opening receiving groove 71, and a screen plate 8 is detachably screwed into the receiving groove 71. The screen plate 8 divides the receiving groove 71 into an upper receiving cavity and a lower receiving cavity. The upper receiving cavity is connected to an upper discharge port 74, and the lower receiving cavity is connected to a lower discharge port 75. A vibration unit 76 is provided at the bottom of the screening box 7, and the vibration unit 76 is used to drive the screening box 7 to vibrate. Specifically, the vibration unit 76 is a motor.

[0053] The sieve plate 8 is detachably connected via the storage groove 71 and screws 78, enabling quick replacement or maintenance of the sieve plate 8. This solves the problem of inconvenient replacement due to fixed installation of the sieve plate 8 in the prior art, improving the maintainability and operational flexibility of the tobacco processing vibrating sieve, reducing downtime, and ensuring reliable fixation of the sieve plate 8 during vibration, thus guaranteeing screening quality and reducing maintenance costs. Simultaneously, the vibration unit 76 drives the screening box 7 to vibrate, ensuring efficient screening; the upper discharge port 74 and lower discharge port 75 output materials of different particle sizes respectively, improving screening flexibility and practicality.

[0054] Specifically, the side of the sieve plate 8 is recessed with a threaded hole 81, and the screening box 7 is provided with a through hole 72. A screw 78 passes through the through hole 72 and is screwed into the threaded hole 81. Two placement plates 77 are also fixed to the inner side wall of the receiving groove 71, and the placement plates 77 are used to support the sieve plate 8.

[0055] In use, the staff removes multiple sets of screws 78 from the sieve plate 8 one by one, then drives the sieve plate 8 to move up from the storage groove 71 and disconnect it from the sieve box 7. A new sieve plate 8 is then replaced, and the sieve plate 8 is moved down into the storage groove 71 and placed on the top surface of the two sets of placement plates 77. Then, the front end of the multiple sets of screws 78 is driven through the through hole 72 by a wrench and then threaded into the threaded hole 81, thereby realizing the replacement of the sieve plate 8.

[0056] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
