[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] At present, the tobacco industry mainly uses silk storage cabinets for material storage. Installing a sizing roller at the exit of the silk storage cabinet to sizing the material can alleviate the problem of uneven material discharge. The sizing roller is mainly composed of three parts: power, transmission, and execution. Among them, the execution part mainly uses a rake roller, which is equipped with several to dozens of rakes according to the length.

[0004] At present, the rake nails on the material leveling roller are generally rigid structures, and the shape is straight strips or bent in the middle. When the rake nails are running, they have a tearing effect on tobacco leaves, tobacco shreds and other materials, which does not meet the current industry's requirements for low shred rate and low fragment rate. At the same time, it will also cause problems such as high dust and large tobacco leaf loss during the production process. Utility Model Content

DETAILED DESCRIPTION

[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] Embodiment 1

[0032] like Figure 1 , Figure 2 As shown, the utility model proposes a flexible material leveling roller mechanism, and the material leveling roller mechanism 2 includes a roller shaft 203, a lever column 204, a lever pin 205 and a torsion spring 208;

[0033] A plurality of mounting holes for mounting the shifting post 204 are provided along the circumference of the shifting roller shaft 203. The shifting post 204 is a hollow cylindrical structure with one end arranged in the mounting hole on the shifting roller shaft 203 and the other end being an open end. A first limiting groove and a second limiting groove are respectively provided on the upper surface and the lower surface of the open end of the shifting post 204. The first limiting groove and the second limiting groove are arranged opposite to each other and are both connected with the open end and the inner cavity of the shifting post 204.

[0034] The pin 205 is rotatably arranged at the open end of the shift column 204 through the first pin shaft 2061, one end of the torsion spring 208 is connected to the shift column 204, and the other end is connected to the pin 205; a limiting column is provided at the end of the pin 205 connected to the shift column 204, and the length of the limiting column is greater than the length of the second limiting groove on the shift column 204, so that a certain angle is formed between the pin 205 and the shift column 204.

[0035] The multiple groups of shifting posts 204 in the utility model are staggeredly installed on the shifting roller, one end of each group of shifting posts 204 is connected to the shifting pin 205 through the first pin shaft, and a limiting post is arranged at the end of the shifting pin 205, and the limiting post cooperates with the second limiting groove of the shifting post 204 so that the shifting pin 205 can be arranged at a certain angle relative to the shifting post 204; the uniformity of tobacco materials in conveying can be improved well, and the crushing of tobacco materials can be greatly reduced.

[0036] As a further technical solution, Figure 3 , Figure 4 As shown, first pin holes are respectively provided on the two side surfaces of the open end of the shifting column 204 and the shifting pin 205 , and the shifting pin 205 is rotatably connected to the shifting column 204 by inserting the first pin 2061 into the first pin hole.

[0037] As a further technical solution, fixing plates 207 are provided on both sides of the push pin 205 , a second pin shaft 2062 is provided between the fixing plates 207 on both sides, and the other end of the torsion spring 208 is fixedly disposed on the second pin shaft 2062 .

[0038] Specifically, in the utility model, the fixed plate 207 is installed on the push pin 205 through the second pin shaft 2062, and the torsion spring 208 is installed on the pin shaft and the two arms act on the push column 204 and the push pin 205 respectively; that is, under the joint action of the pin shaft, the fixed plate 207 and the torsion spring 208, the push pin 205 and the push column 204 form a flexible connection and can maintain a certain angle; because the torsion spring 208 has elastic force, if the force applied to the push pin 205 is too large, it will only bend inward, that is, it will compress the torsion spring 208, which can reduce the breakage of the tobacco material 4 and the material leveling roller 22 is not easily damaged.

[0044] As a further technical solution, a conveying channel 3 is further provided below the discharge port 105 of the tobacco storage cabinet 1 , and the conveying channel 3 is used to receive and transport the tobacco material 4 dropped by the leveling roller mechanism 2 .

[0045] The use process of the utility model is as follows:

[0046] When the tobacco material in the silk storage cabinet reaches the storage time, the internal conveying unit 103 is powered by the power unit 104 to slowly transport the tobacco material in the cabinet to the side of the discharge port 105. When the tobacco material approaches the discharge port 105, the material leveling roller 2 unit is started, and the motor 201 drives the roller to rotate. The pins 205 on the roller are flexibly connected to the poles 204 installed on the roller through the action of the pin shaft, the fixing plate, the torsion spring 208, etc. and form a certain angle. That is, under the drive of the motor 201, multiple groups of flexible pins 205 contact the tobacco material 4, and the tobacco material 4 is evenly pushed to the conveying channel 3 below the discharge port 105 of the silk storage cabinet.
