[0019] Figure 2 for Figure 1 Schematic diagram of the local structure in. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0021] like Figure 1-Figure 2As shown, an embodiment of the present application provides an online tobacco leaf structure modification device for beating and re-drying, which is applied to the beating and stemming process of tobacco leaves. In the beating and re-drying production line, the tobacco leaves need to be processed by a beating machine so that the leaves and stems of the tobacco leaves are separated from each other, and the tobacco leaves are broken up so that the leaf size structure meets the subsequent production needs. The production line has the following requirements for the size structure of the tobacco leaves: the lower the content rate of large leaves in the tobacco leaves, the better, and the higher the content rate of medium leaves in the tobacco leaves, the better. However, at the current stage, when the leaves are beated and stemmed, the content rate of large leaves in the produced tobacco leaves is higher, while the content rate of medium leaves is lower. Therefore, for the existing process, it is necessary to reduce the content rate of large leaves in the tobacco leaves and increase the content rate of medium leaves. The online tobacco leaf structure modification device for beating and re-drying of the present application aims to achieve a lower content rate of large leaves in the produced tobacco leaves and an increase in the content rate of medium leaves in the produced tobacco leaves after the tobacco leaves are beated and stemmed.

[0022] The on-line tobacco leaf structure modification device for beating and re-drying comprises a tobacco leaf conveying device 100 and a tobacco leaf processing bin 200. The tobacco leaf conveying device 100 is used to convey tobacco leaves to be processed. The tobacco leaf conveying device 100 has a feeding end and a discharging end. The tobacco leaves enter the tobacco leaf processing bin 200 and are beated. The tobacco leaf processing bin 200 has a feeding port 201 and a discharging port 202. The discharging end of the tobacco leaf conveying device 100 is communicated with the feeding port 201 of the tobacco leaf processing bin 200 so as to convey tobacco leaves to the tobacco leaf conveying device 100 and the inside of the tobacco leaf processing bin 200.

[0023] In this embodiment, the tobacco conveying device 100 can be a belt conveyor, a vibrating screen, or a rocker-type vibrating trough.

[0024] Preferably, a leaf beating movable knife is rotatably arranged on the tobacco flow path between the feed port 201 and the discharge port 202 in the tobacco processing bin 200, a leaf beating fixed knife is arranged on the side wall of the tobacco processing bin 200, and a porous frame is arranged around the leaf beating movable knife in the tobacco processing bin 200. On the one hand, the leaf beating fixed knife and the leaf beating movable knife cooperate with each other to alternately damage the tobacco leaves, so that the leaves and the tobacco stems are separated from each other, and large leaves can also be damaged. On the other hand, the leaf beating movable knife and the frame cooperate with each other to further tear and The large leaves are further crushed, which reduces the content of large leaves and increases the content of medium leaves. Therefore, after the tobacco conveying device 100 conveys the tobacco leaves to be processed to the tobacco processing bin 200, the large leaves can be effectively destroyed under the cooperation of the leaf beating knife and the leaf beating fixed knife, as well as the interaction between the leaf beating knife and the porous frame, thereby reducing the content of large leaves in the output tobacco leaves and increasing the content of medium leaves in the tobacco leaves, so that the output leaf structure is more in line with the needs of the production line, which is beneficial to improving the quality of cigarette products.

[0025] Preferably, the leaf beating movable knife includes a rotating shaft 301, which is horizontally arranged. A plurality of movable blades 302 are evenly arranged on the rotating shaft 301, and the plurality of movable blades 302 are connected to the outer periphery of the rotating shaft 301. The movable blades 302 have a certain length, and the length direction of the movable blades 302 is the radial direction of the rotating shaft 301. The rotating shaft 301 can be driven to rotate by a driving motor, so that the rotating shaft 301 drives the plurality of leaf beating movable knives to rotate. Leaf beating fixed knives are arranged on both outer sides of the horizontal release of the leaf beating movable knife inside the tobacco processing chamber 200. The arrangement of the leaf beating fixed knives at two positions can further improve the efficiency of tobacco leaf beating, and more In order to further reduce the proportion of large leaves and increase the proportion of medium leaves, each leaf-beating fixed knife includes a plurality of fixed blades 402, and the plurality of fixed blades 402 are arranged at intervals along the horizontal direction. The arrangement direction of the fixed blades 402 and the axial direction of the rotating shaft 301 are parallel to each other. When the movable blades 302 rotate, the movable blades 302 and the fixed blades 402 pass through each other alternately. When the rotating shaft 301 drives the plurality of movable blades 302 to select and grab, each movable blade 302 periodically passes through the gap between each adjacent fixed blade 402, so that the fixed blades 402 and the movable blades 302 cooperate with each other to hit and tear the tobacco leaves.

[0026] In this embodiment, a frame is arranged around the lower part of the leaf beating knife. Preferably, the frame is arc-shaped and surrounds the lower half of the leaf beating knife. The tobacco leaves fall onto the leaf beating knife from above, and then the leaf beating knife and the fixed leaf beating knife cooperate to beat the leaves, and the leaf beating knife and the porous frame cooperate to beat the leaves. The frame has multiple holes. When the movable blade 302 rotates with the tobacco leaves through the internal space of the frame, the movable blade 302 and the frame cooperate with each other to tear the tobacco leaves.

[0027] Preferably, an arc segment 201 is provided on the inner wall of the tobacco processing bin 200, and the arc segment 201 is arranged around a part of the upper part of the leaf beating knife. In this embodiment, in the horizontal direction, the inner walls of the tobacco processing bin 200 on both sides of the rotating shaft 301, the inner wall on one side is vertical, and the arc segment 201 is on the inner wall on the other side. The arc segment 201 surrounds the upper part of the leaf beating knife. Under the action of the arc segment 201, the pre-treated tobacco leaves are squeezed and shredded, which can further improve the leaf beating effect on the tobacco leaves.

[0028] In this embodiment, the middle part of the arc segment 201 arches out toward the direction of the leaf-beating movable blade, that is, the middle part of the arc segment 201 is closer to the outermost side of the movable blade 302, and the two sides of the arc segment 201 are relatively far away from the outermost side of the movable blade 302, so that the tobacco leaves can enter the gap more smoothly, and a buffer-like squeezing is formed on the tobacco leaves, which is more conducive to the fragmentation of the tobacco leaves.

[0029] Preferably, the arc radius of the arc segment 201 is not greater than the rotation radius of the outermost side of the moving blade 302, so that the arc segment 201 has sufficient curvature compared to the leaf-beating moving tool, and the squeezing and crushing of tobacco leaves are smoother. The minimum distance between the arc segment 201 and the outermost side of the moving blade 302 can be set according to actual conditions, preferably 1-5 cm.

[0030] In this embodiment, inside the tobacco processing bin 200, on the side where the arc segment 201 is set, the upper part of the arc segment 201 extends to the feed port 201 of the tobacco processing bin 200, and the lower part of the arc segment 201 extends to the position of the fixed blade 402 on this side, and the upper sides of the frame extend to the positions of the fixed blades 402 on both sides respectively. In this way, a continuous front-to-back multi-stage leaf beating path is formed, which improves the leaf beating effect on the tobacco leaves and helps to reduce the content rate of large leaves in the tobacco leaves. In the horizontal direction, the tobacco leaves The discharge port 202 and the arc segment 201 of the processing bin 200 are located on the same side of the leaf beating movable knife. Driven by the rotating shaft 301, the rotating direction of the movable knife 302 is: from the arc segment 201 toward the fixed knife 402 on the corresponding side, then rotates to the front half of the frame, then reaches the discharge port 202 of the tobacco leaf processing bin 200, and then rotates to the back half of the frame. The leaves that meet the size requirements are discharged through the discharge port, and the tobacco leaves that are too large continue to be crushed under the stirring of the movable knife.
