Description

Technical Field

[0001] This application relates to the field of tobacco processing equipment technology, and in particular to a tobacco stem sorting device. Background Technology

[0002] Tobacco stem sorting devices are key equipment in tobacco processing. Their main function is to effectively separate tobacco stems from other components, thereby improving the quality of tobacco products and the utilization rate of raw materials. Traditional sorting processes mainly rely on manual operation or simple mechanical devices, which suffer from technical bottlenecks such as low sorting efficiency and insufficient accuracy.

[0003] However, existing sorting devices still have several technical shortcomings in actual operation, mainly reflected in the lack of amplitude adjustment function. Due to the differences in physical properties (such as particle size and density) between different batches of tobacco stems, precise adjustment of amplitude parameters is required to achieve effective stratification and separation of materials. The fixed amplitude design of current equipment cannot be dynamically adjusted according to material characteristics, leading to the following problems: First, the material cannot form an ideal stratification state on the screen surface, resulting in incomplete separation of high-quality stems from impurities, directly affecting the quality of the final product; second, inappropriate amplitude can lead to abnormal material movement—too small an amplitude can easily cause material accumulation and blockage, while too large an amplitude can cause material to be thrown off the screen surface prematurely. Both situations reduce screening efficiency, prolong the production cycle, and are difficult to meet the needs of modern large-scale production.

[0004] Therefore, it is necessary to design a tobacco stem sorting device to solve the above problems. Utility Model Content

[0005] In view of this, in order to overcome the shortcomings of the prior art, this utility model provides a tobacco stem sorting device, which effectively solves the problem that the existing sorting device cannot adjust the amplitude according to the material characteristics.

[0021] 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. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0025] According to the present invention, a tobacco stem sorting device is provided, such as... Figures 1 to 6 As shown, this tobacco stem sorting device is used for breaking up and sorting materials such as tobacco stems, and can select a suitable sorting method according to the different materials. The tobacco stem sorting device includes a sorting section 1 and a breaking up section 2.

[0026] In the following description, reference will be made to Figures 1 to 6 The detailed structure of the sorting section 1 and the dispersing section 2 of the tobacco stem sorting device is described in detail.

[0027] like Figures 1 to 6 As shown, in this embodiment, the sorting unit 1 includes a first driving component and a sorting frame component. The first driving component is disposed at the bottom of the sorting frame component and includes a first motor 101 and a connecting group. The first motor 101 drives the sorting frame component to rotate through the connecting group. The first motor 101 can be, for example, a stepper motor, whose output end can rotate in a corresponding cycle according to the received instructions. The user can adjust the controller (e.g., a PLC controller) connected to the stepper motor to make the controller issue periodic instructions to the stepper motor, thereby adjusting the rotation speed of the first motor 101. This allows the operator to select the corresponding sorting mode according to the sorting intensity and the physical characteristics of different batches of tobacco stems.

[0028] Furthermore, the dispersing unit 2 is located at the top of the sorting frame assembly, where it disperses the material. The dispersed material is then sorted inside the sorting frame assembly by the action of the first driving component. The material is first dispersed by the dispersing unit 2 at the top of the sorting frame assembly, breaking up tightly tangled tobacco clumps and loosening the bond between the stems and tobacco, thus preparing the material for subsequent sorting and improving efficiency and accuracy. After the tobacco is dispersed, the operator can adjust the first motor 101 according to different types of tobacco or production process requirements, ensuring it has the required output frequency. Then, the dispersed material is manually moved from the top of the sorting frame assembly to its interior, and the first motor 101 is started for sorting.

[0029] This tobacco stem sorting device, through the cooperation of sorting section 1 and dispersing section 2, enables the dispersing and sorting of tobacco stem materials. Dispersing section 2 quickly breaks up tightly tangled materials, providing pretreatment before sorting and improving work efficiency and sorting accuracy. Through the first drive component and sorting frame component of sorting section 1, operators can adjust the appropriate sorting amplitude according to different types of tobacco or different production process requirements, adapting to the material characteristics to achieve effective stratification and separation of materials, thereby improving sorting accuracy. This tobacco stem sorting device has a simple overall structure and compact design, requiring only one operator to complete the material dispersing and sorting operations. While meeting production requirements, it saves manpower and resources, improving production efficiency and accuracy.

[0030] Preferably, such as Figures 1 to 3As shown, in this embodiment, the sorting frame assembly may include multiple sorting frames arranged from top to bottom. In this embodiment, it may include three sorting frames arranged from top to bottom: a first sorting frame 110, a second sorting frame 111, and a third sorting frame 112. The first sorting frame 110 is used to receive the dispersing unit 2, and the material is dispersed by the dispersing unit 2 within the first sorting frame 110. Since the first motor 101 is directly connected to the third sorting frame 112, the sorting amplitude of the third sorting frame 112, located at the bottom, is greater than that of the second sorting frame 111. The operator can first place the dispersed material in the second sorting frame 111 for preliminary sorting, and then place the pre-sorted material into the third sorting frame 112 for secondary sorting. Alternatively, the material can be directly placed into sorting frames with different amplitudes as needed.

[0031] Furthermore, adjacent sorting frames are connected by elastic tabs. The first sorting frame 110 and the second sorting frame 111 are connected by a first elastic tab 108, and the second sorting frame 111 and the third sorting frame 112 are connected by a second elastic tab 109. Each sorting frame can be formed into an approximately cuboid shape, and two opposite side walls of the four side walls of the cuboid structure are respectively provided with two connection points for installing elastic tabs. The elastic tabs can be installed on the side walls of two adjacent sorting frames by bolts and nuts.

[0032] Preferably, in the embodiments, the first elastic sheet 108 and the second elastic sheet 109 are both made of spring steel. This material has a high elastic limit, fatigue strength, and good hardenability and tempering stability, which can ensure that it maintains stable elastic properties during long-term high-frequency vibration transmission and is not prone to deformation or breakage.

[0033] Preferably, in this embodiment, the lengths of the first elastic sheet 108 and the second elastic sheet 109 are 70mm and 55mm, respectively. This ensures good elastic buffering and power transmission while avoiding poor support or resonance during vibration due to excessive length. Furthermore, since the first elastic sheet 108 and the second elastic sheet 109 are continuously subjected to high-frequency vibration and stress during device operation, wear and tear are inevitable. Under normal tobacco stem sorting workload, it is recommended to conduct a comprehensive inspection of these two elastic sheets every 500-800 hours of operation. If obvious wear marks, cracks, or a significant decrease in elasticity are found on the surface of the elastic sheets, they should be replaced promptly to ensure that the vibration transmission effect and sorting accuracy of the sorting device are not affected.

[0034] Preferably, such as Figures 1 to 3As shown in the embodiment, the elastic sheet between the bottom sorting frame and the adjacent sorting frame is inclined. The second elastic sheet 109 between the second sorting frame 111 and the third sorting frame 112 is also inclined. The second elastic sheet 109 is designed with an inclined structure. On the one hand, the inclined design allows the force generated by the third sorting frame 112 during vibration to be transmitted to the second sorting frame 111 at a more reasonable angle. When the third sorting frame 112 vibrates due to centrifugal force, the inclined second elastic sheet 109 can convert some of the vertical vibration energy into a horizontal component force, causing the second sorting frame 111 to produce a certain displacement and vibration in the horizontal direction. This allows the tobacco stems to be tumbled and screened more thoroughly within the second sorting frame 111, improving sorting efficiency. On the other hand, the inclined structure helps to disperse the stress borne by the elastic sheet. Compared with a horizontally placed elastic sheet, the inclined second elastic sheet 109 has a more uniform stress distribution when subjected to vibration force, which can effectively reduce the risk of fatigue damage caused by local stress concentration, extend its service life, and ensure the stable operation of the entire sorting device.

[0035] Preferably, such as Figure 4 and Figure 5 As shown, in this embodiment, the connection assembly may include a fixing block 102, a fixing member 103, a connecting block 104, and a connecting member. The output end of the first motor 101 is provided with the fixing block 102. The connecting block 104 is connected to the fixing block 102 through the fixing member 103. The two ends of the connecting member are respectively connected to the connecting block 104 and the sorting frame located at the bottom. The fixing member 103 may be, for example, a wing screw, and the fixing block 102 and the connecting block 104 are connected by the wing screw.

[0036] Preferably, such as Figure 4 and Figure 5 As shown, in this embodiment, the connector may include a connecting rod 105 and a hollow tube 106. The hollow tube 106 is sleeved on the connecting rod 105, and the connecting rod 105 and the hollow tube 106 are rotatable relative to each other. The hollow tube 106 is connected to the sorting frame located at the bottom, and the connecting rod 105 is connected to the connecting block 104. The connecting rod 105 and the hollow tube 106 are eccentrically positioned with respect to the output end of the first motor 101. One end of the connecting rod 105 is fixed by the connecting block 104, and the other end passes through the interior of the hollow tube 106. The other end of the hollow tube 106 is installed at the bottom of the third sorting frame 112 through the cooperation of a fixing plate and bolts and nuts.

[0037] Preferably, such as Figures 1 to 4 As shown, in this embodiment, the tobacco stem sorting device may further include a base plate 3, and the bottom of the sorting frame assembly is connected to the base plate 3 via a spring assembly. In this embodiment, the spring assembly may include four spring elements 107, which are respectively disposed at the four bottom corners of the third sorting frame 112.

[0038] Thus, when the first motor 101 is turned on, it drives the fixed block 102 to rotate at a constant speed. The connecting block 104 rotates along with the fixed block 102 via the wing screw. The connecting rod 105 drives the hollow tube 106 and the third sorting frame 112 to begin circular motion. Under the centrifugal force generated by the circular motion, the spring assembly is stretched. The degree of spring stretching is related to the movement speed of the third sorting frame 112 and the magnitude of the centrifugal force. The centrifugal force is constrained by the rotation radius of the third sorting frame 112, thus realizing the function of flexibly adjusting the amplitude according to needs. During vibration, the spring 107 not only provides elastic support for the third sorting frame 112 but also acts as a buffer to prevent damage to the equipment due to excessive vibration. At the same time, it enhances the vibration effect, allowing the tobacco to tumble fully within the third sorting frame 112, creating favorable conditions for subsequent sorting work.

[0039] Preferably, such as Figure 2 As shown, in this embodiment, the dispersing unit 2 is detachably mounted on the top sorting frame. The dispersing unit 2 can be disassembled separately for maintenance and repair.

[0040] Preferably, such as Figure 6 As shown, in this embodiment, the disintegration unit 2 may include a second motor 201, a disintegration frame 202, and a disintegration component. The second motor 201 is disposed on the top of the disintegration frame 202, and its output end is connected to the disintegration component, driving the disintegration component to rotate. The second motor 201 may also be, for example, the stepper motor driven by the controller described above.

[0041] Preferably, such as Figure 6 As shown, in this embodiment, the dispersing component may include a first umbrella-shaped rod group 203 and a second umbrella-shaped rod group 204. The second umbrella-shaped rod group 204 is disposed at the bottom of the first umbrella-shaped rod group 203. The top surface of the sorting frame assembly (i.e., the bottom surface of the first sorting frame 110) is a plane, and the orthographic projection area of ​​the first umbrella-shaped rod group 203 on the plane is larger than the orthographic projection area of ​​the second umbrella-shaped rod group 204 on the plane. The two dispersing components with different sorting areas can ensure that the material located in the middle and sides of the first sorting frame 110 is fully dispersed. Both the first umbrella-shaped rod group 203 and the second umbrella-shaped rod group 204 can be formed into an umbrella-shaped structure by multiple rods extending outward along the central axis, and the umbrella-shaped structure can achieve comprehensive dispersing.

[0042] Preferably, such as Figures 1 to 3 and Figure 6As shown, in this embodiment, a slot 206 is provided on the outer wall of the top sorting frame, and a locking block 207 that mates with the slot 206 is provided on the inner wall of the dispersing frame 202 of the dispersing section 2. The dispersing frame 202 is detachably installed on the first sorting frame 110 through the engagement of the slot 206 and the locking block 207. This connection method is simple and quick to operate, greatly shortening the equipment assembly time. When the equipment needs maintenance or component replacement, the operator can easily pull the locking block 207 out of the slot 206 to separate the dispersing section 2 from the sorting section 1, facilitating the inspection, repair, and replacement of each component. In addition, this quick-connect and disassembly design makes it easy to place tobacco stems into the first sorting frame 110 during tobacco stem sorting, improving the convenience of production operations. When the locking block 207 is inserted into the locking slot 206, the inner wall of the locking slot 206 will hold the locking block 207, restricting its movement in all directions, providing a stable installation base for the disassembly frame 202.

[0043] The tobacco stem sorting device operates as follows: First, the rotation speed of the first motor 101 is adjusted according to the required amplitude. Then, the first motor 101 drives the fixed block 102 to rotate. The connecting block 104 rotates along with the fixed block 102 under the fastening action of the wing screw. This causes the connecting rod 105 to drive the hollow tube 106 and multiple sorting frames to perform circular motion. Under the action of centrifugal force, the spring 107 at the bottom of the third sorting frame 112 is stretched, and the sorting frame vibrates synchronously. The first elastic plate 108 and the second elastic plate 109 can transmit the circular motion and vibration, thereby achieving effective separation of tobacco stems.

[0044] This tobacco stem sorting device, through the cooperation of a sorting section and a dispersing section, enables the dispersing and sorting of tobacco stem materials. The dispersing section quickly breaks up tightly tangled materials, providing pretreatment before sorting and improving efficiency and accuracy. Through the first drive component and sorting frame component of the sorting section, operators can adjust the appropriate sorting amplitude according to different types of tobacco or different production process requirements, adapting to the material characteristics to achieve effective stratification and separation, thus improving sorting accuracy. The overall structure of this tobacco stem sorting device is simple and compact, requiring only one operator to complete the material dispersing and sorting operations. While meeting production requirements, it saves manpower and resources, improving production efficiency and accuracy.
