Description

Technical Field

[0001] This application relates to the field of tobacco machinery technology, specifically to an anti-accumulation material guiding device. Background Technology

[0002] Tobacco processing is a crucial step in cigarette production, directly impacting the final product's fill power, combustion performance, and smoking experience. The shredding process, as the core step in processing, demands extremely high standards for the uniformity, size, and structural integrity of the tobacco shreds. The feeding vibrating carriage of the shredder, especially the widely used horizontal feeding system, plays a vital role in ensuring the uniform, continuous, and stable delivery of tobacco leaves to the shredder. The rational design of its feed channel directly determines the uniformity of feeding and the physical state of the tobacco leaves, forming the foundation for ensuring shredding quality and production efficiency.

[0003] Although most existing horizontal feeding vibrating mills are equipped with mechanical structures (such as spring buffers) to drive the material guide channel to vibrate and assist material flow, material accumulation within the guide channel (especially in the inlet and outlet areas) remains a prominent problem in practice. Tobacco leaves are highly susceptible to sticking, stagnation, and localized aggregation in these areas, leading to severely uneven distribution of the material, manifested as areas that are too thick or too thin. This accumulation not only hinders the smooth flow of tobacco leaves but also causes them to fold and compress at the accumulation points, resulting in uneven compaction and the formation of internal voids. Simultaneously, the accumulation area exacerbates friction between tobacco leaves and collisions with the channel walls, significantly increasing the breakage and fragmentation rate, and wasting raw materials. Frequent accumulation also forces equipment shutdowns for cleaning, severely impairing production continuity and efficiency. Ultimately, these problems lead to a decline in the quality of the shredded tobacco, manifesting as defects such as "large flakes," "serrated tobacco," and "hollowed-out tobacco." The core technical problem is that even with vibration assistance, the existing flat or simply inclined inner surface structure of the material guide channel is still difficult to effectively prevent tobacco leaves from adhering and accumulating in key areas (especially the inlet and outlet), thereby causing a chain reaction of uneven material distribution, uneven compaction, increased breakage, and equipment operation interruption.

[0004] Therefore, this application proposes an anti-accumulation material guiding device that can change the local contour of the inner surface of the channel, disrupt the favorable conditions for material accumulation, and promote the dispersion and smooth flow of tobacco leaves. Utility Model Content

[0005] The main purpose of this application is to provide an anti-accumulation material guiding device, which aims to solve the technical problem that the material guiding channel of the existing feeding vibrating car is prone to tobacco leaf accumulation at the inlet / outlet due to its flat structure.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] An anti-accumulation material guiding device is applied to a feeding vibrating car equipped with a vibration mechanism, comprising: an inclined material guiding trough and a material guiding plate connected to its high end and extending to the middle of the trough, the low end of the material guiding trough being an output port, a first anti-accumulation block being provided on the top surface of the material guiding plate, and a second anti-accumulation block being provided on the inner bottom surface of the low end of the material guiding trough.

[0008] Both the first anti-accumulation block and the second anti-accumulation block are three-dimensional conical raised structures. By reconstructing the contours of the bottom surface of the guide trough and the top surface of the guide plate, the static balance of material accumulation is disrupted.

[0009] As a further improvement of this application, both the first anti-accumulation block and the second anti-accumulation block are four-sided pyramidal structures. The four side edges of the first anti-accumulation block extend along both ends of the extending direction of the guide plate and both sides of the width direction of the guide groove, respectively. The four side edges of the second anti-accumulation block extend along both ends of the axial direction of the guide groove and both sides of the width direction of the guide groove, respectively.

[0010] As a further improvement of this application, the side edge length of the first anti-accumulation block adjacent to the input port of the guide plate is greater than the side edge length adjacent to the output port of the guide trough; the side edge length of the second anti-accumulation block adjacent to the output port of the guide trough is greater than the side edge length adjacent to the input port of the guide plate.

[0011] As a further improvement of this application, the extending direction of the guide plate forms a first angle with the horizontal plane, and the extending direction of the guide groove forms a second angle with the horizontal plane. The first angle is greater than the second angle, and the first angle is an acute angle.

[0012] The technical solution provided in this application may include the following beneficial effects:

[0013] This application utilizes a three-dimensional conical raised structure on the top surface of the guide plate and the outlet section of the guide chute to completely reconstruct the guide interface contour, directly addressing the production bottleneck caused by stubborn material accumulation in the inlet and outlet areas of the feeding vibrating car. This design disrupts the static equilibrium of materials in critical areas, forcing linearized tobacco leaf flow and eliminating the root causes of tobacco leaf folding, uneven compaction, and voids in the tobacco cake caused by material accumulation. Simultaneously, it avoids frictional damage to the tobacco leaves caused by traditional guide plates, significantly reducing breakage losses. After the guide interface is reconstructed, the tobacco leaf conveying process achieves continuous flow without stagnation, greatly reducing the frequency of downtime for unclogging, effectively improving the continuity and stability of equipment operation, and meeting the high-efficiency production requirements of tobacco processing.

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are merely some, not all, of the embodiments of this application. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] Figure 1 An embodiment of an anti-accumulation material guiding device of this application is shown, see [link to relevant documentation]. Figure 1 In this embodiment, the anti-accumulation guiding device is applied to a feeding vibrating car equipped with a vibration mechanism, including: a guiding trough 1, a guiding plate 2, a first anti-accumulation block 3, and a second anti-accumulation block 4.

[0022] Among them, see Figure 1The feed chute 1 is inclined, with its lower end serving as the output port. The feed guide plate 2 is connected to the higher end of the feed chute 1 and extends towards the center. A first anti-accumulation block 3 is located on the top surface of the feed guide plate 2, and a second anti-accumulation block 4 is located on the inner bottom surface of the lower end of the feed chute 1. Both the first anti-accumulation block 3 and the second anti-accumulation block 4 are three-dimensional conical raised structures to reconstruct the contours of the bottom surface of the feed chute 1 and the top surface of the feed guide plate 2. Through the three-dimensional conical raised structures on the top surface of the feed guide plate 2 and the outlet section of the feed chute 1, the contours of the feed interface are completely reconstructed, directly addressing the production bottleneck caused by stubborn material accumulation in the inlet and outlet areas of the feeding vibrating car. This design disrupts the static equilibrium of materials in critical areas, forcing the tobacco leaf flow to be linearized and guided, eliminating the problems of tobacco leaf folding, uneven compaction, and gaps in the tobacco cake caused by material accumulation at the source. Simultaneously, it avoids frictional damage to the tobacco leaves caused by the traditional feed guide plate 2, significantly reducing breakage losses. After the flow interface is redesigned, the tobacco leaf conveying process achieves continuous flow without stagnation, significantly reducing the frequency of downtime for unclogging and effectively improving the continuity and stability of equipment operation, thus meeting the needs of high-efficiency tobacco processing.

[0023] Further, see Figure 2 Both the first anti-accumulation block 3 and the second anti-accumulation block 4 are four-sided pyramidal structures. The four side edges of the first anti-accumulation block 3 extend along both ends of the extension direction of the guide plate 2 and both sides of the width direction of the guide trough 1, respectively. The four side edges of the second anti-accumulation block 4 extend along both ends of the axial direction of the guide trough 1 and both sides of the width direction of the guide trough 1, respectively. Through the four-sided pyramidal structure and the directional extension of the side edges, the problems of tobacco leaf folding and uneven distribution caused by the structural defects of the guide plate 2 are eliminated, achieving linear flow guidance without dead angles.

[0024] Further, see Figure 2 The length of the side edge of the first anti-accumulation block 3 near the input port of the guide plate 2 is greater than the length of the side edge of the adjacent output port of the guide trough 1; the length of the side edge of the second anti-accumulation block 4 near the output port of the guide trough 1 is greater than the length of the side edge of the adjacent input port of the guide plate 2. By setting the geometric constraint that the side edge of the input port of the first anti-accumulation block 3 is longer than the output port and the side edge of the output port of the second anti-accumulation block 4 is longer than the input port, the gaps in the tobacco cake caused by uneven compaction and mutual folding of tobacco leaves are eliminated, and the dense and homogeneous conveying of the shredded raw materials is achieved.

[0025] Further, see Figure 1 The extension direction of the guide plate 2 forms a first inclination angle with the horizontal plane, and the extension direction of the guide trough 1 forms a second inclination angle with the horizontal plane. The first inclination angle is greater than the second inclination angle, and the first inclination angle is an acute angle. By coordinating the steep inclination angle of the guide plate 2 and the gentle inclination angle of the guide trough 1, the defect of uneven tobacco leaf distribution under the horizontal feeding method is overcome, and a seamless connection between accelerated inlet feeding and smooth outlet spreading is achieved, eliminating gaps in the tobacco cake from the root.

[0026] Optionally, the first inclination angle of 50°-70° ensures that the tobacco leaves are accelerated to detach and prevent splashing, while the second inclination angle of 10°-40° balances the outlet flow rate and the requirement to prevent material piling. When the inclination angle ratio α / β≈2.0, the optimal flow state of steep guide and slow laying is formed, which eliminates the inherent uneven distribution and void defects of horizontal feeding.

[0027] For example, the guide chute 1 is made of stainless steel with a length of 30mm and a thickness of 30mm. The bottom plate of the guide chute is 1038mm long and 375mm wide. Two mounting plates of the same size (adjustable tilt angle of 25°) are welded to its low-position output section. The guide plate 2 is a 65° tilted base plate of 1038×375×30mm, which is welded to the high end of the guide chute 1. The first anti-accumulation block 3 extends towards the inlet side based on an isosceles triangle with a 79° guide angle (200mm high). The first section has a 700 mm (74° inclination) section and extends 200 mm to the outlet side, forming a conical ridge with a total length of 900 mm. The second anti-accumulation block 4 is based on an isosceles triangle with a 115° guide angle (105 mm high), extending 765 mm (8° inclination) to the inlet side and 270 mm (21° inclination) to the outlet side, forming a progressive guide cone with a total length of 1035 mm. The two cones are then fully welded and fixed to form a non-stagnant tobacco leaf flow channel.

[0028] In this embodiment, a structural solution is proposed to address industry pain points such as persistent material accumulation, tobacco leaf folding, and uneven material distribution caused by the flatness of the material guiding interface in the inlet and outlet areas of the horizontal feeding vibrating car. This solution involves setting a first anti-accumulation block 3 on the top surface of the guide plate 2 and a second anti-accumulation block 4 at the outlet section of the guide trough 1. The flow guiding interface is reconstructed using a quadrangular pyramid structure with directionally extended side edges (the first side edge extends along the flow / width direction, and the second side edge is similarly extended). A flow gradient is formed based on the geometric constraints that the length of the side edge at the inlet is greater than that at the outlet (first side edge) and the length of the side edge at the outlet is greater than that at the inlet (second side edge). This, combined with the angle difference design of the steep inlet (50°-70°) and the gentle outlet (10°-40°), achieves a seamless transition from accelerated detachment to uniform spreading of the tobacco leaves, eradicating accumulation foci, eliminating gaps in the tobacco cake, and ensuring dense and homogeneous conveying of the tobacco leaf flow. This fundamentally overcomes the quality degradation problem caused by material distribution defects in the shredding process.

[0029] The above description is merely a preferred embodiment of this application and is not intended to limit this application. 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.
