Description

Technical Field

[0001] This utility model relates to the field of tobacco production technology, and in particular to a mixing and homogenizing device and a conveying system. Background Technology

[0002] As the front end of cigarette production, the tobacco processing workshop primarily transforms tobacco leaves into shredded tobacco through a series of production processes. A typical tobacco processing workshop consists of three main production lines: leaf processing, shredded tobacco, and stem processing, in addition to a flavoring room and storage room. In the shredded tobacco processing workshop, the main task of the air separator used on the shredded tobacco line is to separate clumps, stems, tobacco lumps, and other impurities from the dried tobacco, thereby improving the purity of the finished tobacco product.

[0003] The separation of stems and shredded tobacco is mainly achieved through a combination of flotation and drift separation. However, existing air classifiers have certain shortcomings in the removal of stems and shredded tobacco after drying: First, the removal of stems and shredded tobacco is insufficient, resulting in a small amount being removed. Second, when the material entering the flotation chamber of the air classifier is thick in the middle, or when a large amount of stems and shredded tobacco is removed, the gap between the loosening rollers is small, making it easy for the upper loosening roller in the air classifier to become clogged and jammed, causing material shortages and machine shutdowns. In severe cases, this can affect product quality. These two factors seriously affect the purity of the finished tobacco shreds, and insufficient tobacco purity has negative impacts on product quality, cost, brand reputation, and the environment.

[0004] Therefore, there is an urgent need for a mixing and homogenizing device that can enhance quality control in production and ensure the purity of tobacco shreds in order to maintain market competitiveness and consumer trust. Utility Model Content

[0005] The purpose of this invention is to provide a mixing and homogenizing device and a conveying system, which can improve the purity and production efficiency of material screening; avoid material blockage and jamming of the upper filament roller in the air classifier caused by excessive rejection pressure; the structure is simple and can enhance the quality control of production and manufacturing.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A mixing and homogenizing device, comprising:

[0008] A support frame, which is fixed to the air separator;

[0009] The driving components are symmetrically arranged on the upper left and right sides of the feeding direction. The two symmetrical driving components can be brought closer or further apart to adjust the distance between them. The driving components are selectively fixed to the bracket.

[0010] A stirring assembly is provided, which is configured one-to-one with the driving component. The stirring assembly includes a connecting shaft and a stirring wheel. One end of the connecting shaft is connected to the stirring wheel, and the other end of the connecting shaft is connected to the output end of the driving component. The stirring wheel can rotate parallel to the feeding direction to stir the material.

[0011] As an optional technical solution for the mixing and homogenizing device, two supports are symmetrically arranged above the left and right sides of the feeding direction, and the supports on the same side are correspondingly arranged with the driving component.

[0012] As an optional technical solution for the mixing and homogenizing device, multiple driving components are provided on one side, and each of the multiple driving components is correspondingly provided with a bracket on the same side.

[0013] As an optional technical solution for the mixing and homogenizing device, the bracket is provided with a waist-shaped hole, the length direction of the waist-shaped hole is perpendicular to the feeding direction, and the length direction of the waist-shaped hole is horizontally set, and the feeding direction is horizontally set; the driving member is located above the waist-shaped hole, and the output end of the driving member can pass through and extend out of the waist-shaped hole.

[0014] As an optional technical solution for the mixing and homogenizing device, the output end of the drive component is connected to the connecting shaft by a pin.

[0015] As an optional technical solution for the mixing and homogenizing device, the mixing wheel is movably connected to the connecting shaft, and the mixing wheel can move in the vertical direction to adjust the distance between the mixing wheel and the material.

[0016] As an optional technical solution for the mixing and homogenizing device, the mixing wheel is threadedly sleeved on the outside of the connecting shaft, and the mixing assembly also includes a nut, which can selectively lock the height position of the mixing wheel.

[0017] As an optional technical solution for the mixing and homogenizing device, the mixing wheel is provided with mixing claws on the side that contacts the material, and multiple mixing claws are arranged at intervals around the mixing wheel.

[0018] As an optional technical solution for the mixing and homogenizing device, the driving component is a pneumatic motor.

[0020] The beneficial effects of this utility model are:

[0021] The mixing and homogenizing device provided by this utility model includes a support, a driving component, and a mixing assembly. The support is fixed on the air classifier. The driving components are symmetrically arranged on the upper left and right sides of the feeding direction. The two symmetrical driving components can be moved closer or further apart to adjust their distance. The driving components are selectively fixed to the support. The mixing assembly is arranged one-to-one with the driving component. The mixing assembly includes a connecting shaft and a mixing wheel. One end of the connecting shaft is connected to the mixing wheel, and the other end of the connecting shaft is connected to the output end of the driving component. The driving component drives the mixing wheel to rotate parallel to the feeding direction, which is used to agitate the material and spread it evenly. The distance between the two driving components, i.e., the center distance between the two mixing wheels, can be adjusted according to the feeding flow rate to facilitate the subsequent removal of impurities such as stalks and improve the purity of the material screening. This avoids the possibility of the upper unwinding roller in the air classifier getting clogged due to the large thickness of the material in the middle or the large amount of stalks and clumps that need to be removed per unit time, thus improving production efficiency and the practicality of the air classifier.

The belt conveyor is used to convey materials into the trough of the vibrating conveyor. The feeding direction is the conveying direction of the vibrating conveyor. The material falls from the belt conveyor into the trough of the vibrating conveyor. When the material is conveyed in the trough, it passes between two mixing wheels. The mixing wheels are used to agitate the material located in the trough and spread the material to both sides of the trough, so as to achieve the purpose of spreading the material evenly in the trough.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] Specifically, such as Figure 1As shown in the diagram, this utility model discloses a mixing and homogenizing device including a support 100, a driving component 200, and a mixing assembly. The support 100 is fixed on an air classifier. The driving components 200 are symmetrically arranged on the upper left and right sides of the feeding direction. The two symmetrical driving components 200 can be moved closer or further apart to adjust their distance. The driving components 200 are selectively fixed to the support 100. The mixing assembly is arranged one-to-one with the driving components 200. The mixing assembly includes a connecting shaft 310 and a mixing wheel 320. One end of the connecting shaft 310 is connected to the mixing wheel 320, and the other end of the connecting shaft 310 is connected to the output end of the driving component 200. The driving component 200 drives the mixing wheel 320 to rotate parallel to the feeding direction, which is used to agitate the material and spread it evenly. The distance between the two driving components 200, i.e., the center distance between the two mixing wheels 320, can be adjusted according to the feeding flow rate to facilitate the subsequent removal of impurities such as stalks and improve the purity of the material screening. The material entering the air separator is evenly spread, which facilitates the removal of impurities. This avoids the possibility of the upper unwinding roller in the air separator getting clogged due to the large thickness of the material in the middle or the large amount of stems and clumps that need to be removed per unit time. This improves production efficiency and the practicality of the air separator. Moreover, compared with the previous air separator, more stems and other impurities are removed, and the screening is more thorough, which effectively improves the purity of the finished tobacco and provides great help and support for subsequent production.

[0033] For example, the two mixing wheels 320 can rotate relative to each other, which can spread the material more evenly.

[0034] In this embodiment, the drive component 200 is set as a pneumatic motor, which can adjust the center distance between the two mixing wheels 320 according to the flow rate of the material. With the pneumatic motor driving the mixing wheels 320, the rotation speed can be infinitely adjusted, which plays a role in flexible mixing and spreading, and is convenient and reliable.

[0035] Specifically, two brackets 100 are symmetrically arranged on the upper left and right sides of the feeding direction. The brackets 100 on the same side are corresponding to the drive component 200, which can stabilize the structure of the mixing and equalizing device and facilitate individual disassembly and installation.

[0036] Furthermore, based on the site environment and existing equipment dimensions, a reasonable design and drawing are carried out. Multiple drive components 200 are set on one side, and multiple drive components 200 are set with corresponding brackets 100 on the same side. In order to make the paving effect more stable, a stepped paving method can be adopted, corresponding to multiple sets of mixing wheels 320. The height of the first set of mixing wheels 320 in contact with the material is slightly lower than the height of the material stack. The height of the second set of mixing wheels 320, the third set of mixing wheels 320, etc. in contact with the material decreases sequentially until the material is paved to the expected effect. At the same time, the contact area between the mixing wheel 320 and the material gradually increases.

[0037] In this embodiment, the stirring wheel 320 is movably connected to the connecting shaft 310. The stirring wheel 320 can move vertically to adjust the distance between the stirring wheel 320 and the material, improving the versatility of the connecting shaft 310. For example, through the design of the lower thread of the connecting shaft 310, the stirring wheel 320 is threaded onto the outside of the connecting shaft 310. The stirring assembly also includes nuts, and the connecting shaft 310 and the stirring wheel 320 are connected and locked by two nuts. The nuts can selectively lock the height position of the stirring wheel 320, allowing for fine-tuning of the stirring wheel 320 in the vertical direction.

[0038] Specifically, the bracket 100 has a waist-shaped hole 101, the length direction of which is perpendicular to the feeding direction, and the length direction of the waist-shaped hole 101 is horizontally arranged, as is the feeding direction. The drive unit 200 is located above the waist-shaped hole 101, and the output end of the drive unit 200 can pass through and extend out of the waist-shaped hole 101, facilitating the adjustment of the center distance between the two stirring wheels 320. In this embodiment, the output end of the drive unit 200 is connected and fixed to the connecting shaft 310 by a pin, which facilitates installation.

[0039] Optionally, the mixing wheel 320 is provided with mixing claws 321 on the side that contacts the material. Multiple mixing claws 321 are arranged at intervals around the circumference of the mixing wheel 320, which makes it easier to sort the material and avoids the mixing wheel 320 squeezing the material and doing useless work. The mixing claws 321 are more effective when the material is stacked at a large height, and can be spread in place quickly, reducing the impact of impurities entanglement on the operation of the mixing wheel 320.

[0040] This mixing and homogenizing device can be specifically applied to tobacco processing production lines. It features a novel overall design, attractive appearance, complete functions, convenient installation and adjustment, and easy operation and maintenance.

[0041] This utility model also discloses a conveying system, including the aforementioned mixing and homogenizing device, as well as a belt conveyor and a vibrating conveyor. The belt conveyor is used to convey materials into the trough of the vibrating conveyor, with the feeding direction being the same as the conveying direction of the vibrating conveyor. The material falls from the belt conveyor into the trough of the vibrating conveyor. The mixing and homogenizing device is installed at the interface between the belt conveyor and the vibrating conveyor; the bracket 100 is installed and fixed on the discharge mask shell of the belt conveyor, with the installation height adjusted to a suitable position on the surface of the trough of the vibrating conveyor below the mixing wheel 320. When the material is conveyed in the trough, it passes between the two mixing wheels 320. The mixing wheels 320 are used to agitate the material in the trough, spreading the material to both sides of the trough, achieving the purpose of evenly spreading the material in the trough. This system can be used to evenly mix and spread tobacco materials in the trough of a vibrating conveyor, facilitating subsequent equipment to remove impurities and perform air separation in the tobacco materials, thus effectively improving the purity of tobacco materials.

[0042] 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 various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
