Description

Technical Field

[0001] This utility model relates to the field of tobacco processing technology, and in particular to a tobacco processing device. Background Technology

[0002] In tobacco processing, after storage or addition, tobacco shreds often clump together due to changes in moisture content, prolonged settling time, and uneven adhesion of additives, forming lumpy tobacco shreds. If these lumps are directly introduced into subsequent processes without treatment, it will lead to problems such as uneven filling and altered combustion characteristics, seriously affecting the quality of cigarettes. Therefore, they must be broken up to meet process specifications.

[0003] Currently, the industry commonly uses spike-tooth and drum-type tobacco breaking equipment. The spike-tooth type uses rotating spikes to impact the tobacco clumps, while the drum type uses a rotating drum with spikes or protrusions to break up clumps through friction. Although these two types of equipment can achieve basic breaking functions, they have obvious drawbacks: the breaking force is poorly controlled, and the contact between the spikes and tobacco can easily cause fiber breakage; moreover, they are bulky and require a dedicated foundation frame, making them only suitable for new factories or large-scale production line renovations. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies, and this utility model provides a tobacco processing device.

[0005] This utility model provides the following technical solution: A tobacco processing device includes a body, a dispersing roller, and a drive assembly.

[0006] The machine body is provided with a processing chamber, and the upper end of the machine body is provided with a feed inlet communicating with the processing chamber. The bottom of the processing chamber is provided with a discharge outlet. The tobacco shreds to be broken up can enter the processing chamber through the feed inlet. The breaking up roller is installed in the processing chamber, and the rotating shaft of the breaking up roller is horizontally inserted through the machine body. The side wall of the breaking up roller is provided with a first protrusion, and the inner wall of the processing chamber is provided with a second protrusion corresponding to the first protrusion. The first protrusion and the second protrusion are both made of a flexible material. The driving assembly is installed on the machine body and is connected to the rotating shaft of the breaking up roller. The driving assembly drives the breaking up roller to rotate in the processing chamber, which enables the first protrusion and the second protrusion to move relative to each other, thereby breaking up the clumps of tobacco shreds in the processing chamber.

[0007] As a further improvement to the above technical solution, the driving component includes a drive motor, which is mounted on the machine body, and the motor shaft of the drive motor is connected to the rotating shaft of the dispersing roller via a synchronous belt drive.

[0008] As a further improvement to the above technical solution, the drive motor is mounted on the lower side of the machine body.

[0009] As a further improvement to the above technical solution, the first protrusion is evenly distributed in a plurality of circumferential directions on the side of the dispersing roller, and the second protrusion is provided in a plurality of horizontal directions on the inner wall of the processing cavity, with the first protrusion and the second protrusion being arranged alternately.

[0010] As a further improvement to the above technical solution, the second protrusion is positioned on the same horizontal plane as the axis of rotation of the dispersing roller.

[0011] As a further improvement to the above technical solution, a vertically arranged movable long groove corresponding to the second protrusion is provided on the side wall of the processing cavity, a movable seat is provided on the outer wall of the processing cavity, a movable cavity is provided inside the movable seat, and the movable cavity is connected to the movable long groove; a movable block is provided inside the movable cavity, and the movable block is fixedly connected to the end of the second protrusion away from the dispersing roller, and elastic elements are connected between the movable block and the inner side walls at both the upper and lower ends of the movable cavity.

[0012] As a further improvement to the above technical solution, adjusting rods are vertically threaded through the inner walls of the upper and lower ends of the movable cavity, and support plates are provided at the ends of the two adjusting rods near the movable block. The elastic element is disposed between the support plate and the movable block.

[0013] As a further improvement to the above technical solution, an isolation plate is provided between the movable block and the second protrusion. The isolation plate fits snugly against the outer wall of the processing cavity, and the isolation plate can block the movable long groove.

[0014] As a further improvement to the above technical solution, the opening area of ​​the feed port is larger than the cross-sectional area of ​​the processing cavity.

[0015] As a further improvement to the above technical solution, the machine body is provided with a conveyor belt, and the conveying surface of the conveyor belt is located below the discharge port.

[0016] Compared with related technologies, the beneficial effects of this utility model are: The tobacco processing device provided by this utility model, when breaking up the tobacco to be processed, firstly, evenly loads the tobacco to be processed into the processing chamber through the feed inlet, and then starts the drive assembly, whose power is transmitted to the horizontally arranged breaking rollers in the processing chamber. During the rotation of the breaking rollers, the first and second protrusions generate relative displacement, and the tobacco clumps are gradually broken up through mechanical pulling action.

[0017] When encountering a large, hard clump of tobacco, the resistance at the moment of contact between the first and second protrusions causes the flexible part to deform, preventing the tobacco from breaking due to rigid collision. By using a pulsed rotation mode set by the control system, combined with the elastic recovery characteristics of the protrusions, the gradual decomposition of clumps can be achieved.

[0018] This invention, through a flexible spike dynamic avoidance mechanism, not only ensures adaptability to tobacco shreds in different states, but also effectively solves the technical problem that traditional spike-tooth shredders easily cause excessive breakage of tobacco shreds.

[0028] like Figure 1 As shown, an embodiment of this utility model provides a tobacco processing device, including a machine body 100, a dispersing roller 200, and a drive assembly 300.

[0029] The machine body 100 has a processing chamber 110. The upper end of the machine body 100 has a feed inlet 120 communicating with the processing chamber 110, and the bottom of the processing chamber 110 has a discharge outlet 130. The tobacco to be dispersed can enter the processing chamber 110 through the feed inlet 120. A dispersing roller 200 is installed inside the processing chamber 110, and the rotating shaft 220 of the dispersing roller 200 is horizontally mounted on the machine body 100. The side wall of the dispersing roller 200 has a first protrusion 210, and the inner wall of the processing chamber 110 has a protrusion that communicates with the material being dispersed. The first protrusion 210 corresponds to the second protrusion 111. Both the first protrusion 210 and the second protrusion 111 are made of flexible materials. Specifically, the first protrusion 210 can adopt a composite structure of TPU (thermoplastic polyurethane elastomer) and 304 stainless steel core. Its outer flexible material has a Shore hardness of 85A and can produce 3-5mm elastic deformation when subjected to a tensile force exceeding 15N. The second protrusion 111 can be made of ultra-high molecular weight polyethylene (UHMWPE), with an elongation at break of up to 350%, which can effectively buffer impact force. The drive assembly 300 is mounted on the machine body 100 and is connected to the rotating shaft 220 of the dispersing roller 200. The drive assembly 300 drives the dispersing roller 200 to rotate in the processing chamber 110, which enables the first protrusion 210 and the second protrusion 111 to move relative to each other, thereby dispersing the clumps of tobacco in the processing chamber 110.

[0030] The tobacco processing apparatus provided in this embodiment first uniformly feeds the tobacco shreds into the processing chamber 110 through the feed inlet 120 when breaking up the tobacco shreds to be processed. Then, the drive assembly 300 is activated, and its power is transmitted to the horizontally arranged breaking rollers 200 in the processing chamber 110. During the rotation of the breaking rollers 200, the first protrusion 210 and the second protrusion 111 generate relative displacement, and the tobacco shreds are gradually broken up through mechanical pulling.

[0031] When encountering a large, hard clump of tobacco, the resistance at the moment of contact between the first protrusion 210 and the second protrusion 111 causes deformation of the flexible part, preventing tobacco breakage due to rigid collision. By using the drive assembly 300 to drive the dispersing roller 200 to periodically rotate forward and backward, it enters a pulse-like rotation mode. Combined with the elastic recovery characteristics of the protrusions, it can achieve gradual decomposition of clumps, thereby greatly reducing the probability of tobacco being pulled apart and damaged, and ensuring the quality of tobacco production and processing.

[0032] like Figure 2As shown, in some specific embodiments, the drive assembly 300 includes a drive motor 310, which is mounted on the machine body 100. The motor shaft of the drive motor 310 is connected to the rotating shaft 220 of the dispersing roller 200 via a synchronous belt 320. Through the synchronous belt 320 transmission structure, the rotational power output by the drive motor 310 is transmitted through three stages: the driving pulley on the motor shaft, the synchronous belt 320, and the driven pulley on the rotating shaft 220, ultimately transforming into the stable rotation of the dispersing roller 200. Compared with traditional gear transmission or direct coupling, this transmission method has significant advantages such as low operating noise, high transmission efficiency, and long maintenance cycle. It can provide continuous and reliable rotational power for the dispersing roller 200, meeting the stability requirements of the equipment during tobacco processing.

[0033] like Figure 3 As shown, in some specific embodiments, the drive motor 310 is mounted on the lower side of the body 100, which helps to ensure that the overall center of gravity of the body 100 is lower, reducing the risk of tipping over and ensuring the reliability of this embodiment.

[0034] In some specific embodiments, the first protrusion 210 is evenly distributed in a plurality of circumferential directions on the side of the dispersing roller 200, and the second protrusion 111 is provided in a plurality of horizontal directions on the inner wall of the processing cavity 110, with the first protrusion 210 and the second protrusion 111 being arranged alternately.

[0035] In some specific embodiments, the second protrusion 111 is positioned on the same horizontal plane as the axis of rotation 220 of the dispersing roller 200.

[0036] like Figure 4 As shown, in some specific embodiments, the sidewall of the processing cavity 110 is provided with vertical movable long grooves 112 corresponding one-to-one in number and position to the second protrusions 111. The width of the movable long groove 112 is 0.5-1mm larger than the diameter of the second protrusions 111, ensuring smooth sliding guidance of the second protrusions 111 within the groove, while preventing tobacco from getting stuck by controlling the gap between the groove wall and the protrusions (≤0.2mm). An independent movable seat 140 is provided on the outer wall of the processing cavity 110 corresponding to the position of each movable long groove 112.

[0037] The movable cavity 141 is fitted with a movable block 142 that can slide in the vertical direction. The end of the second protrusion 111 that is away from the dispersing roller 200 is fixed to the movable block 142 by means of thread or other connection. In order to ensure the reset performance of the movable block 142, elastic elements 143 are respectively installed between the movable block 142 and the inner sidewalls of the upper and lower ends of the movable cavity 141.

[0038] During operation, when the second protrusion 111 encounters severely clumped tobacco, the reaction force generated by the tobacco clump against the protrusion overcomes the preload of the elastic element 143, causing the movable block 142 to drive the second protrusion 111 to slide upwards or downwards along the guide direction of the movable groove 112 (the sliding stroke range is controlled within 5-15mm). During this process, the relative displacement distance between the first protrusion 210 and the second protrusion 111 dynamically changes, transforming the original meshing and dispersing action into a flexible avoidance action, effectively preventing tobacco breakage caused by rigid collisions. Once the second protrusion 111 passes the clumped tobacco, the elastic potential energy stored in the elastic element 143 is rapidly released, pushing the movable block 142 to cause the second protrusion 111 to quickly rebound and return to its original position. This rebound action generates a reverse impact dispersing force on the tobacco clump, working synergistically with the continuous rotational dispersing action of the first protrusion 210.

[0039] Through the combined action of the elastic deformation of the first protrusion 210, the sliding displacement of the second protrusion 111, and the elastic element 143, this embodiment realizes a triple floating and dispersing mechanism. When processing tobacco shreds with high moisture content and high agglomeration rate, it can significantly increase the whole shred rate, reduce the broken shred rate, and significantly improve the tobacco shred processing quality and production environment.

[0040] In some specific embodiments, adjusting rods 144 are vertically threaded through the inner walls of the upper and lower ends of the movable cavity 141. Support plates 145 are provided at the ends of the two adjusting rods 144 near the movable block 142. An elastic element 143 is disposed between the support plate 145 and the movable block 142. The elastic element 143 adopts a combined spring structure, specifically composed of two sets of compression springs. During actual processing, operators can adjust the floating parameters of the second protrusion 111 by rotating the adjusting rods 144 to handle tobacco with different physical properties. The specific adjustment logic is as follows: When processing high-humidity tobacco with excessive moisture content and clumping rate, rotating the upper and lower adjusting rods 144 clockwise moves the support plate 145 away from the movable block 142. At this time, the pre-compression of the elastic element 143 decreases, and the second protrusion 111 can slide against a small resistance when encountering a tobacco clump, effectively avoiding fiber breakage due to rigid compression and improving the whole tobacco yield.

[0041] Conversely, when processing dry tobacco with low moisture content and clumping rate, rotating the adjusting rod 144 counterclockwise moves the support plate 145 closer to the movable block 142, reducing the distance between them. At this time, the pre-compression of the elastic element 143 increases, and the resistance required for the sliding of the second protrusion 111 increases. Under the premise of ensuring the integrity of the tobacco, the dispersing efficiency is improved by enhancing the interaction force between the protrusions.

[0042] In some specific embodiments, a partition plate 146 is provided between the movable block 142 and the second protrusion 111. The partition plate 146 fits snugly against the outer wall of the processing cavity 110. The partition plate 146 can block the movable long groove 112 to prevent the tobacco in the processing cavity 110 from leaking out of the movable long groove 112, thus avoiding waste and preventing it from affecting the normal operation of the movable block 142 and the elastic element 143, thereby improving the reliability of this embodiment.

[0043] In some specific embodiments, the opening area of ​​the feed port 120 is larger than the cross-sectional area of ​​the processing cavity 110, which facilitates improving the feeding efficiency into the processing cavity 110.

[0044] In some specific embodiments, the machine body 100 is provided with a conveyor belt 150, the conveying surface of the conveyor belt 150 is located below the discharge port 130, which facilitates the rapid transfer of tobacco shreds discharged from the processing chamber 110 and improves the overall processing efficiency of tobacco shreds.
