Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, and more specifically, to a serrated beating roller device for threshing and redrying. Background Art

[0002] The leaf beating process of tobacco leaves is an important process in the threshing and redrying process of cigarette production. The purpose of this process is to separate the leaf flesh on the tobacco leaves from the main veins of the tobacco stalks, obtain tobacco leaves with a certain size distribution, and separate qualified tobacco leaves through an air separator to complete the subsequent processing process. In the prior art, except for a small amount of high-quality cigarettes that use manual labor or a leaf cutting machine to implement this process, in the main industrial production, it is implemented through a leaf beater. The beating roller is the main working component in the leaf beater, providing the kinetic energy for tearing the tobacco leaves during the leaf beating process, and cooperating with the frame to achieve the effect of removing the leaf flesh from the main veins of the tobacco stalks.

[0003] The current traditional leaf beater has some drawbacks: low leaf tearing efficiency. The leaf tearing efficiency has always been an important indicator for measuring the leaf beating efficiency of the leaf beater during the leaf beating process. During the leaf beating process, the methods of using multi-stage leaf beating or increasing the rotation speed of the beating roller are usually used to ensure the complete separation of the leaf flesh from the main veins of the tobacco stalks. Although the leaf flesh can be completely removed from the tobacco stalks finally, the produced tobacco leaves are broken due to entering the leaf beaters at all levels multiple times and at a relatively high rotation speed of the beating roller, resulting in a high breakage rate and a large amount of fragmented tobacco, causing waste of raw materials. Therefore, improving the leaf tearing efficiency of a single leaf beater can reduce the number of leaf beating stages and effectively improve the leaf beating quality. The beating knives of the traditional leaf beater are arranged in a straight line at a certain angle on the end face. Since the tobacco leaves enter the leaf beater evenly at a certain feeding flow rate, such an arrangement will cause the beating roller to contact the tobacco leaves for beating at a certain cycle, which is particularly obvious at low rotation speeds, thus affecting the uniformity and stability of the discharge.

[0004] Moreover, in terms of installation and maintenance, the maintenance and installation process of the beating knives is relatively cumbersome and requires single-piece disassembly and replacement. And the wear of the beating knives is usually relatively constant, and usually the whole is replaced, which is time-consuming and laborious, increasing the labor intensity of the operators.

[0005] Therefore, how to provide a serrated beating roller device for threshing and redrying has become a technical problem that needs to be solved urgently in this field. Summary of the Utility Model

[0029] As Figures 1 to 4 shown, an embodiment of the present invention provides a serrated roller device for leaf threshing and redrying, including: a main shaft 1, a leaf threshing assembly 2 and a fixing assembly 3.

[0030] The leaf - threshing component 2 includes a fixture 21 and a leaf - threshing knife 22. The fixtures 21 are respectively arranged on both sides of the leaf - threshing knife 22. The fixture 21 is used to fix the leaf - threshing knife 22.

One side of the leaf - threshing knife 22 is set as a serrated structure 23.

[0031] The fixing component 3 is used to fix the leaf - threshing knife 22.

[0032] Specifically, two fixtures 21 fix one leaf - threshing knife 22. The distance between the two fixtures 21 is equal to the thickness of the leaf - threshing knife 22. By clamping one leaf - threshing knife 22 with the two fixtures 21 and fixing the leaf - threshing knife 22 on the main shaft 1 through the fixing component 3, when the leaf - threshing knife 22 needs to be replaced, only the fixing of the leaf - threshing knife 22 by the fixing component 3 needs to be released, and then the leaf - threshing knife 22 can be replaced. The structure is simple and easy to operate, making the installation and maintenance of the leaf - threshing knife 22 more convenient. It should be noted that the structure of the fixing component 3 is not limited here.

[0033] In this utility model, the fixtures 21 are respectively arranged on both sides of the leaf - threshing knife 22 to fix the leaf - threshing knife 22. The first end of the fixture 21 is connected to the main shaft 1, and the second end of the fixture 21 is connected to the leaf - threshing knife 22. One side of the leaf - threshing knife 22 is set as a serrated structure 23. By using the fixture 21 to fix the leaf - threshing knife 22, the structure is simple, making the installation and maintenance of the leaf - threshing knife 22 more convenient, and effectively reducing the labor intensity of the operator. And one side of the leaf - threshing knife 22 is set as a serrated structure 23, increasing the contact area and friction area between the leaf - threshing knife 22 and the tobacco leaves, thereby improving the leaf - tearing efficiency and ensuring the uniformity and stability of the discharge.

[0034] In an embodiment of the serrated - type beating roller device for tobacco leaf threshing and redrying of this utility model, as Figure 4 shown, the serrated structure 23 is composed of serrations arranged in sequence. The angle of each serration tip of the serrated structure 23 is 30 degrees.

[0035] Specifically, one side of the leaf - threshing knife 22 is provided with a serrated structure 23, and the other side of the leaf - threshing knife 22 is a planar structure.

[0036] In this utility model, the serrated structure 23 is composed of serrations arranged in sequence, and the angle of each serration tip of the serrated structure 23 is set to 30 degrees. Then, multiple serrations are used to thresh the tobacco leaves, enabling the leaf flesh to be completely removed from the tobacco stalk, further improving the leaf - tearing efficiency, and further ensuring the uniformity and stability of the discharge.

[0037] In an embodiment of the serrated - type beating roller device for tobacco leaf threshing and redrying of this utility model, as Figures 1 to 2As shown, the serrated roller device for leaf threshing and redrying further includes a driving motor and a driving shaft 4. The driving shaft 4 penetrates through the main shaft 1, and the driving motor is connected to the driving shaft 4 to drive the driving shaft 4 to rotate.

[0038] In the present utility model, by passing the driving shaft 4 through the main shaft 1 and connecting the driving motor to the driving shaft 4, the driving motor drives the driving shaft 4 to rotate, the driving shaft 4 drives the main shaft 1 to rotate, and then drives the leaf threshing knife 22 to rotate, so that the leaf threshing knife 22 can perform leaf threshing on the tobacco leaves, thereby ensuring that the leaf flesh is completely separated from the main vein of the tobacco stem, and further improving the leaf tearing efficiency.

[0039] Furthermore, the rotational speed of the main shaft 1 is 450 - 700 rpm.

[0040] In an embodiment of the serrated roller device for leaf threshing and redrying of the present utility model, the fixture 21 is arranged along the outer peripheral wall of the main shaft 1, and the included angle between the central axes of two adjacent fixtures 21 is 60 degrees.

[0041] Specifically, the leaf threshing knife 22 is arranged along the circumferential direction of the main shaft 1. Six leaf threshing knives 22 are arranged along the circumferential direction of the main shaft 1, and the six leaf threshing knives 22 are respectively fixed by two fixtures 21.

[0042] In the present utility model, by arranging the fixture 21 along the outer peripheral wall of the main shaft 1 and making the included angle between the central axes of two adjacent fixtures 21 be 60 degrees, the leaf threshing knife 22 can continuously perform leaf threshing on the tobacco leaves, effectively ensuring the leaf tearing effect.

[0043] In an embodiment of the serrated roller device for leaf threshing and redrying of the present utility model, as Figures 1 to 3 shown, there are multiple fixtures 21 and multiple leaf threshing knives 22. The multiple fixtures 21 and the multiple leaf threshing knives 22 are respectively arranged at intervals along the axial direction of the main shaft 1.

[0044] In the present utility model, by arranging multiple fixtures 21 and multiple leaf threshing knives 22, and the multiple fixtures 21 and the multiple leaf threshing knives 22 are respectively arranged at intervals along the axial direction of the main shaft 1. During the leaf threshing process, the multiple leaf threshing knives 22 perform leaf threshing on the tobacco leaves, improving the leaf threshing efficiency, enabling more tobacco leaves to be threshed at the same time, reducing the leaf threshing time, effectively improving the work efficiency, and by arranging multiple leaf threshing knives 22, the contact frequency between the leaf threshing knives 22 and the material flow can be increased, thereby improving the uniformity of the material and quality formed after being processed by the leaf threshing knives 22.

[0045] In an embodiment of the serrated roller device for leaf threshing and redrying of the present utility model, as Figures 1 to 3As shown, the fixing component 3 includes two connecting holes 31 and fixing pin rods 32. The two connecting holes 31 are respectively arranged at the second end of the fixture 21, and the fixing pin rods 32 respectively penetrate through the connecting holes 31 and the leaf-beating knives 22.

[0046] Specifically, the leaf-beating knives 22 are provided with two mounting holes 24. The two fixing pin rods 32 respectively penetrate through the connecting holes 31 and the mounting holes 24 to fix the leaf-beating knives 22 on the fixture 21.

[0047] Furthermore, the length of the fixing pin rod 32 is slightly less than the length of the main shaft 1, so that the fixing pin rod 32 penetrates through a plurality of leaf-beating knives 22 and a plurality of fixtures 21, and thus the fixing pin rod 32 can fix the plurality of leaf-beating knives 22 and the fixtures 21. It should be noted that the structural strength of the fixing pin rod 32 meets the normal operation requirements of leaf-beating.

[0048] In the present utility model, by respectively arranging the two connecting holes 31 at the second end of the fixture 21 and the fixing pin rods 32 respectively penetrating through the connecting holes 31 and the leaf-beating knives 22, the fixing pin rods 32 fix the leaf-beating knives 22. The structure is simple, the cost is low, the use cost and the maintenance cost are reduced, and the installation and maintenance of the leaf-beating knives 22 are more convenient, effectively reducing the labor intensity of the operators.

[0049] The working process of the serrated beating roller device for leaf-beating and redrying of the present utility model is as follows: As Figures 1 to 4 shown, when carrying out the leaf-beating work, the driving motor is connected to the driving shaft 4, so that the driving motor drives the driving shaft 4 to rotate. The rotation of the driving shaft 4 drives the main shaft 1 to rotate, and then drives the leaf-beating knives 22 to rotate. The leaf-beating treatment of the tobacco leaves is carried out through the serrated structure 23 on the leaf-beating knives 22, so that the leaf flesh can be completely removed from the tobacco stalks, improving the leaf-tearing efficiency and ensuring the uniformity and stability of the discharged materials.

[0050] The serrated beating roller device for leaf-beating and redrying of the present utility model has a simple structure and is convenient to use. By designing the leaf-beating knives 22 with the serrated structure 23, the frictional tearing effect between the leaf-beating knives 22 and the tobacco leaves is increased, improving the leaf-tearing efficiency. And the fixing pin rods 32 fix the leaf-beating knives 22. The structure is simple, the cost is low, the use cost and the maintenance cost are reduced, and the installation and maintenance of the leaf-beating knives 22 are more convenient, effectively reducing the labor intensity of the operators.
