Technical Field

[0001] The utility model relates to the technical field of tobacco leaf processing equipment, in particular to a tobacco leaf flattening mechanism. Background Art

[0002] Due to the tobacco leaf harvesting process, a lot of non-tobacco substances such as soil are mixed in the tobacco leaf pile. Therefore, it is necessary to remove as much non-tobacco substances as possible before processing the tobacco leaves. Due to the folding of tobacco leaves and the stacking of tobacco leaves during transportation, a large amount of non-tobacco substances cannot be detected by the detection equipment. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a tobacco leaf flattening mechanism, which can flatten the tobacco leaves, so as to facilitate reliable and effective X-ray imaging of non-smoking foreign bodies and their removal in the later stage.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a tobacco leaf flattening mechanism, including a conveyor belt and a scraper, the scraper is slidably arranged above the conveying end surface of the conveyor belt, and the sliding adjustment direction of the scraper is perpendicular to the conveying end surface of the conveyor belt.

[0005] Furthermore, an assembly is provided above the conveying end surface of the conveyor belt, and an assembly long hole is provided on the assembly, and the length direction line of the assembly long hole is perpendicular to the conveying end surface of the conveyor belt;

[0006] A fixing plate is arranged at the end of the scraper, and the fixing plate is provided with a mounting hole corresponding to the long assembly hole.

[0007] Furthermore, the angle between the end of the scraper and the assembly is 30° to 60°.

[0008] Furthermore, the distance between the bottom of the scraper and the conveying end surface of the conveyor belt is 80 mm to 160 mm.

[0009] Furthermore, a reinforcement piece is provided on the scraper.

[0010] Furthermore, the reinforcement member is located on an end surface of the scraper facing the discharge end of the conveyor belt.

[0011] The beneficial effect of the utility model is that a scraper is added above the conveying end surface of the conveyor belt, and the scraper limits the height of the tobacco leaf output, so that the tobacco leaves are evenly spread on the conveyor belt, thereby reducing the blocking rate of the tobacco leaves on non-tobacco substances. At the same time, the scraper can slide perpendicular to the conveying end surface of the conveyor belt, so that the distance between the scraper and the conveying end surface of the conveyor belt can be appropriately adjusted according to actual needs, thereby improving the flexibility of the overall spreading mechanism.

[0019] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0020] Please refer to Figures 1 to 3 As shown, the utility model is a tobacco leaf flattening mechanism, comprising a conveyor belt 1 and a scraper 2, wherein the scraper 2 is slidably arranged above the conveying end surface of the conveyor belt 1, and the sliding direction of the scraper 2 is perpendicular to the conveying end surface of the conveyor belt 1.

[0021] From the above description, it can be seen that the beneficial effect of the utility model is that: a scraper 2 is added above the conveying end surface of the conveyor belt 1, and the scraper 2 limits the height of the tobacco leaf output, so that the tobacco leaves are evenly spread on the conveyor belt 1, thereby reducing the blocking rate of the tobacco leaves on non-tobacco substances. At the same time, the scraper 2 can slide perpendicular to the conveying end surface of the conveyor belt 1, so that it can appropriately adjust the distance between the scraper 2 and the conveying end surface of the conveyor belt 1 according to actual needs, thereby improving the flexibility of the overall spreading mechanism.

[0022] Please refer to Figure 1 and Figure 4 As shown, further, an assembly part 11 is provided above the conveying end surface of the conveyor belt 1, and an assembly long hole 111 is provided on the assembly part 11, and the length direction line of the assembly long hole 111 is perpendicular to the conveying end surface of the conveyor belt 1;

[0023] A fixing plate 21 is disposed at the end of the scraper 2 , and the fixing plate 21 is provided with a mounting hole 211 corresponding to the long assembly hole 111 .

[0024] As can be seen from the above description, the screw rod of the bolt passes through the assembly long hole 111 and the mounting hole 211, and then the nut and the bolt are threadedly connected to each other so that the fixing plate 21 and the assembly 11 can be located between the nut and the nut of the bolt. The position of the scraper 2 above the conveying end surface of the conveyor belt 1 is fixed by tightening the bolt, and the height of the scraper 2 above the conveying end surface of the conveyor belt 1 is adjusted by loosening the bolt.

[0025] Please refer to Figure 2 As shown, further, the angle between the end of the scraper 2 and the assembly 11 is A. The angle A is preferably 30°, 40°, 45°, 50° and 60°, and the most preferred angle A is 45°.

[0026] It can be seen from the above description that the angle formed between the end assemblies 11 of the scraper 2 can not only achieve the flattening of the tobacco leaves, but also help guide the transportation of the tobacco leaves on the conveyor belt 1.

[0027] Please refer to Figure 3 As shown, further, the distance between the bottom of the scraper 2 and the conveying end surface of the conveyor belt 1 is B. The distance B is preferably 80 mm to 160 mm, and the most preferred distance B is 100 mm to 120 mm.

[0028] Please refer to Figure 4 As shown, further, a reinforcement member 22 is provided on the scraper 2.

[0029] Preferably, the reinforcing member 22 is located on one end surface of the scraper 2 facing the discharge end of the conveyor belt 1. The reinforcing member 22 is located on one end surface of the scraper 2 facing the discharge end of the conveyor belt to avoid the influence of the reinforcing member 22 on the flattening and conveying of tobacco leaves.

[0030] It can be seen from the above description that the reinforcement member 22 can enhance the strength of the scraper 2 to ensure the leveling operation of the scraper 2 .
