Description

[0002] During tobacco processing, metal impurities such as nails and wires may get mixed in with tobacco leaves during transportation and handling. If these metal impurities are not removed in time, they will damage subsequent processing equipment and affect the quality of tobacco products.

[0003] Traditional impurity removal devices typically suspend magnets above the tobacco conveyor belt, using magnetic force to attract metallic impurities. However, this method only removes metallic impurities from the surface of the tobacco leaves on the conveyor belt, failing to effectively remove impurities inside the leaves, resulting in incomplete impurity removal. Therefore, a solution to address these issues is urgently needed. Utility Model Content

The magnetic component includes a driving member, a rotating member, and magnetic elements. The rotating member is convexly connected to the driving member. Multiple magnetic elements are provided, spaced apart on the outer periphery of the rotating member. When the tobacco leaves fall from the output end of the first conveyor belt to the input end of the second conveyor belt, the rotating member rotates to cause the magnetic elements to disperse the tobacco leaves, and the magnetic elements can adsorb metallic impurities in the tobacco leaves.

[0008] Optionally, the magnetic element is plate-shaped, and the thickness direction of the magnetic element is perpendicular to the axial direction of the rotating element.

[0009] Optionally, the rotating component is wheel-shaped, and a plurality of magnetic components are spaced apart around the circumference of the rotating component.

[0017] The beneficial effects of this utility model are:

[0018] This utility model proposes a tobacco leaf impurity removal device for removing metallic impurities from tobacco leaves. It includes a first conveyor belt and a second conveyor belt for transporting tobacco leaves. The output end of the first conveyor belt is higher than the input end of the second conveyor belt. The device also includes a magnetic component located vertically between the output end of the first conveyor belt and the input end of the second conveyor belt. The magnetic component includes a driving member, a rotating member, and magnetic elements. The rotating member is connected to the driving member. Multiple magnetic elements are spaced apart on the outer periphery of the rotating member. When tobacco leaves fall from the output end of the first conveyor belt to the input end of the second conveyor belt, the rotating member rotates to cause the magnetic elements to disperse the tobacco leaves, and the magnetic elements can adsorb metallic impurities from the tobacco leaves. By setting up a first conveyor belt and a second conveyor belt, with the output end of the first conveyor belt higher than the input end of the second conveyor belt, and by setting up a magnetic component located vertically between the output end of the first conveyor belt and the input end of the second conveyor belt, tobacco leaves can fall from the output end of the first conveyor belt to the input end of the second conveyor belt.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] This embodiment proposes a tobacco leaf impurity removal device and a tobacco leaf transport system to solve the problem of incomplete removal of metal impurities from tobacco leaves in the prior art.

[0032] like Figure 1 As shown, the tobacco leaf impurity removal device is used to remove metal impurities from tobacco leaves. It includes a first conveyor belt 1 and a second conveyor belt 2 for transporting tobacco leaves. The output end of the first conveyor belt 1 is higher than the input end of the second conveyor belt 2. The tobacco leaf impurity removal device also includes a magnetic component 3. In the vertical direction, the magnetic component 3 is located between the output end of the first conveyor belt 1 and the input end of the second conveyor belt 2. The magnetic component 3 includes a driving member, a rotating member 31, and magnetic members 32. The rotating member 31 is connected to the driving member. Multiple magnetic members 32 are provided, and the multiple magnetic members 32 are spaced apart on the outer periphery of the rotating member 31. When the tobacco leaves fall from the output end of the first conveyor belt 1 to the input end of the second conveyor belt 2, the rotating member 31 rotates to make the magnetic members 32 disperse the tobacco leaves, and the magnetic members 32 can adsorb metal impurities in the tobacco leaves.

[0033] Understandably, during tobacco processing, metal impurities such as nails and wires may be mixed in with tobacco leaves during transportation and handling. If these metal impurities are not removed in time, they will damage subsequent processing equipment and affect the quality of tobacco products. In the existing technology, a magnet is usually set above the tobacco leaf conveyor belt to attract metal impurities in the tobacco leaves. However, this solution can only remove metal impurities on the surface of the tobacco leaves and cannot effectively remove metal impurities deep in the tobacco leaves, resulting in incomplete impurity removal. This application sets up a first conveyor belt 1 and a second conveyor belt 2, with the output end of the first conveyor belt 1 higher than the input end of the second conveyor belt 2. By setting up a magnetic component 3 located vertically between the output end of the first conveyor belt 1 and the input end of the second conveyor belt 2, tobacco leaves can fall from the output end of the first conveyor belt 1 to the input end of the second conveyor belt 2. During the fall, the tobacco leaves will collide with the magnetic component 3, thereby attracting the metal impurities contained in the tobacco leaves. In addition, through a rotating component 31 connected to the drive component, magnetic components 32 are spaced around the outer periphery of the rotating component 31. When the rotating component 31 rotates, the magnetic components 32 rotate accordingly, breaking up the tobacco leaves and making it easier for the metal impurities contained deep in the tobacco leaves to be attracted by the magnetic components 32, thereby making the cleaning of metal impurities more thorough.

[0034] Optionally, the magnetic element 32 is plate-shaped, and the thickness direction of the magnetic element 32 is perpendicular to the axial direction of the rotating element 31. This arrangement makes it easier for the tobacco leaves to be dispersed by the magnetic element 32, improving the thoroughness of the magnetic element 32's adsorption.

[0035] For example, the magnetic element 32 has a rectangular cross-section, and one long side of the magnetic element 32 is connected to the rotating element 31. This arrangement increases the contact area between the magnetic element 32 and the tobacco leaf, making it easier for metal impurities to be attracted by the magnetic element 32, improving the adsorption effect, and thus improving the reliability of the tobacco leaf impurity removal device.

[0036] Optionally, the rotating component 31 is wheel-shaped, and multiple magnetic components 32 are spaced apart around the circumference of the rotating component 31. This arrangement makes it easier for the rotating component 31 to cooperate with the magnetic components 32, and the overall shape resembles an impeller, which improves the effect of dispersing falling tobacco leaves, thereby improving the structural rationality and user satisfaction of the tobacco leaf removal device.

[0037] Optionally, the magnetic component 32 is made of a strong magnetic material. This configuration enhances the magnetic force of the magnetic component 32, thereby improving the adsorption effect on metallic impurities.

[0038] For example, the magnetic component 32 is made of neodymium iron boron permanent magnet material. Neodymium iron boron permanent magnet material is corrosion resistant and has magnetism in all directions, which improves the impurity adsorption capacity and reliability of the tobacco leaf impurity removal device.

[0039] Of course, other strong magnetic materials can also be selected in other embodiments, depending on the application scenario, and no further restrictions are imposed here.

[0040] Optionally, the number of magnetic components 32 is 6 to 10. This arrangement ensures the adsorption capacity of the magnetic components 3 while avoiding insufficient agitation of the tobacco leaves due to overly dense magnetic components 32, thus improving the structural rationality of the tobacco leaf removal device.

[0041] Of course, the number of magnetic components 32 can also be other values. The selection can be made as needed according to the size of the rotating component 31 and the flow rate of the tobacco leaves. No further restrictions are imposed here.

[0042] Optionally, the magnetic component 32 is an electromagnet. Understandably, when the magnetic component 3 attracts too much metal debris, its attraction capacity will decrease significantly. At this time, the power supply to the magnetic component 32 can be turned off to make it lose its magnetism, and the metal debris will fall off. This setting facilitates the cleaning and adjustment of the magnetic component 3 and improves the ease of use of the tobacco leaf removal device.

[0043] Optionally, the tobacco leaf cleaning device also includes a debris collection component with a collection cavity capable of collecting metal debris that falls from the magnetic component 32. This design prevents metal debris from scattering on the conveyor belt or in the workshop when the power to the magnetic component 32 is turned off, facilitating the collection and processing of metal debris and improving the structural rationality of the tobacco leaf cleaning device.

[0044] For example, the debris collection component is a tipping trolley. This design facilitates the unloading of metal debris after collection, improving operational convenience for workers. Of course, in other embodiments, the debris collection component can also be other types of components, selected as needed according to the application scenario, without further restrictions.

[0045] Optionally, the first conveyor belt 1 and the second conveyor belt 2 are parallel. This arrangement makes it less likely for tobacco leaves to slip off the conveyor belts, improving the reliability of the tobacco leaf removal device.

[0046] Optionally, the drive unit is a speed-adjustable motor. This setting allows the speed of the drive unit to be adjusted as needed according to the flow rate of the tobacco leaves, thereby maximizing the impurity removal effect and improving user satisfaction with the tobacco leaf impurity removal device.

[0047] The tobacco leaf transport system proposed in this embodiment includes a tobacco leaf impurity removal device. The tobacco leaf transport system also includes a first conveyor frame and a second conveyor frame. The first conveyor belt 1 is rotatably mounted on the first conveyor frame. A first drive mechanism is provided on the first conveyor frame and is connected to the first conveyor belt 1 in a transmission manner. The second conveyor belt 2 is rotatably mounted on the second conveyor frame. A second drive mechanism is provided on the second conveyor frame and is connected to the second conveyor belt 2 in a transmission manner.

[0048] The tobacco leaf transportation system implemented here includes a tobacco leaf impurity removal device, which can thoroughly remove metal impurities from the transported tobacco leaves, improving user satisfaction. In addition, the first and second conveyor frames provide installation positions for the first conveyor belt 1 and the second conveyor belt 2, and provide two power sources, the first and second drive mechanisms, which enable the tobacco leaf impurity removal device to operate smoothly and improve the structural rationality of the tobacco leaf transportation system.

[0049] The operation process of the tobacco leaf impurity removal device in this embodiment is as follows:

[0050] First, the first conveyor belt 1 and the second conveyor belt 2 operate under the drive of the first and second drive mechanisms. Turning on the drive mechanism causes the rotating component 31 to rotate, and tobacco leaves fall from the output end of the first conveyor belt 1. These leaves are then dispersed by the rotating magnetic component 32, which attracts metallic impurities from the tobacco leaves. The tobacco leaves then fall to the input end of the second conveyor belt 2 and are carried away by it. Observation shows that when there are many metallic impurities on the magnetic component 32, the tobacco leaf removal device is paused, and the magnetic component 32 is cleaned.

[0051] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
