[0023] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific implementations disclosed below.

[0024] Please refer to Figs. 1 to 4 The tobacco leaf grading pipeline of the embodiment includes a first bearing conveying table 1, a smoke isolation plate 2, a grade sign 3 and a grading table 4.

[0025] The first bearing conveying table 1 is mainly used for bearing and conveying the graded tobacco leaves. The first bearing conveying table 1 can be a pipeline in the form of a belt or a plate chain, and in the working state, the first bearing conveying table drives the graded tobacco leaves to move forward continuously. A plurality of smoke isolation plates 2 are arranged on the first bearing conveying table in the conveying direction. A plurality of grade signs 3 are installed on the first bearing conveying table and located between the adjacent two smoke isolation plates 2. The smoke isolation plate 2 and the grade sign 3 can move back and forth with the first bearing conveying table 1. It should be noted that the grade sign 3 displays the grade of the tobacco leaves. For example, the middle tobacco leaves can be preliminarily divided into four grades, which are arranged repeatedly on the first bearing conveying table 1, so that the graded tobacco leaves can be placed between the two smoke isolation plates 2 (corresponding to the grade sign 3), and then driven by the first bearing conveying table 1 to move forward. A plurality of grading tables 4 are arranged on one side of the first bearing conveying table in the conveying direction. Each grading table 4 is a work station for a sorting technician.

[0026] By arranging the first bearing conveying table 1, the smoke isolation plate 2, the grade sign 3 and the grading table 4, when grading the tobacco leaves, the technician stands in front of the grading table 4 to grade the tobacco leaves, and places the graded tobacco leaves between the smoke isolation plates 2 corresponding to the grade sign 3. The first bearing conveying table 1 drives the graded tobacco leaves to move forward continuously or intermittently. In the moving process, the plurality of work stations also place the graded tobacco leaves between the corresponding smoke isolation plates 2. When transported to the end, a technician stacks or bundles the tobacco leaves between the smoke isolation plates 2 according to the grade. Compared with the traditional single grading table 4, the pipeline realizes continuous grading operation of the tobacco leaves. The technician stands in front of the grading table 4 and does not need to move frequently, and can directly place the graded tobacco leaves between the smoke isolation plates 2 corresponding to the grade sign 3, which is driven by the first bearing conveying table 1 to move forward, greatly improving the grading efficiency and shortening the grading period.

[0027] In order to facilitate operation, the pipeline further comprises a second carrying conveyor 5 which can be a pipeline in the form of a belt or a plate chain and is installed on the other side of the grading table 4, so that the grading table 4 is arranged between the first carrying conveyor 1 and the second carrying conveyor 5. In the working state, the second carrying conveyor continuously moves the tobacco leaves to be graded forward, and the technician of each grading table 4 can take the tobacco leaves from the second carrying conveyor 5 to the grading table 4 for sorting. This structure reduces the inconvenience of the technician to take the tobacco leaves, so that the technician can focus on grading.

[0028] In order to facilitate operation, the first carrying conveyor 1 is provided with mounting seats 6 at intervals, and the grade tags 3 are detachably installed on the mounting seats 6, so that different grade tags 3 can be quickly replaced when different tobacco leaves are graded.

[0029] In order to facilitate operation, the grading table 4 comprises a tobacco placing plate 41 and a dust suction box 42 installed at the bottom of the tobacco placing plate 41. The tobacco placing plate 41 is provided with strip-shaped dust leakage holes 43 in an array, and the dust suction box 42 is funnel-shaped with a large upper part and a small lower part. The broken tobacco generated during grading can fall into the dust suction box 42 through the dust leakage holes 43. A lighting lamp 47 is installed on the tobacco placing plate 41 to facilitate grading operation.

[0030] In order to facilitate dust collection, the pipeline further comprises a dust suction pipe 44 arranged along the conveying direction of the first carrying conveyor 1. The bottoms of the plurality of dust suction boxes 42 are connected to the dust suction pipe 44 through pipelines. The dust suction pipe 44 can be connected to a fan, so that the debris generated by the plurality of grading tables 4 can be uniformly discharged and collected through the dust suction pipe 44, which improves the comfort of the working environment to a certain extent.

[0031] In order to facilitate recycling, a filter plate 45 is installed in the dust suction box 42. The filter plate 45 is provided with filter holes 46, and the diameter of the filter holes 46 is smaller than that of the dust leakage holes 43, so that part of the larger broken tobacco in the dust suction box 42 can be recycled.

[0032] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
