Detailed Description

The technical solution of the embodiment of the material homogenizing roller of the blade redrying machine of the present invention will be clearly and completely described below with reference to the attached drawings of the embodiment of the present invention. It is obvious that the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the scope of the invention.

As shown in figure 1 and figure 2, the utility model provides a blade redrying machine equalizing roller, including pivot 1, commentaries on classics roller 2 and rack 3. The rotating shaft 1 is connected with the rotating roller 2, the rotating roller 2 is sleeved on the rotating shaft 1, and the rotating shaft 1 and the rotating roller can synchronously rotate through fixed connection of keys. The toothed rack 3 is located on the outer surface of the roller 2 and extends in the axial direction of the roller. The rack 3 is a strip-shaped structure and is provided with a plurality of strips, the strips are uniformly arranged along the outer surface of the rotating roller 2, and four strips are preferably arranged on the rack 3. The edge of the rack 3 is provided with a plurality of teeth 4, the teeth 4 are in the shape of cones, and one end with small size is far away from the rotating roller 2. The size of the end with the large cone size is at least 1.5 times of the size of the end with the small cone size; the size of the end with the large size of the cone is at least 2 times of the size of the end with the small size. The cone is a quadrangular pyramid, a truncated quadrangular pyramid, a cone or a truncated cone. In a preferred embodiment, the teeth 4 are shaped as quadrangular pyramids, and in a triangle comprising sides extending in the axial direction of the turning roll 2 and the vertex angles of the quadrangular pyramids, the angles comprising the vertex angles of the quadrangular pyramids are obtuse angles, which is more advantageous for avoiding the tobacco leaves from being entangled on the rack 3. In another embodiment, the teeth 4 are shaped as cones, and in a triangular cross-section formed by the diameter of the base circle of the cone and the apex of the cone, the angle containing the apex of the cone is an obtuse angle.

One end of the rotating shaft 1 is fixedly connected with the motor 7 through a bearing, the other end of the rotating shaft 1 is fixed on the ground through a rotating shaft support (not shown), the motor 7 is fixed on the motor support 8, and the motor 7 can drive the rotating shaft 1 to rotate so as to drive the rotating roller 2 and the rack 3 on the rotating roller 2 to rotate.

The utility model provides a blade redrying machine mixing roll is located the top of conveyer belt 5, evenly arranges a plurality of transport claws 6 on the surface of conveyer belt 5. During the rotation of the motor 7 and the transmission of the conveying belt 5, the top end of the tooth 4 closest to the motor is just not contacted with the top end of the conveying claw 6. As shown in figure 1, the conveyer belt 5 is driven anticlockwise, the rotating shaft 1 and the rotating roller 2 synchronously rotate clockwise, the plurality of racks 3 rotate clockwise, and the rotating speed of the racks 3 is greater than the driving speed of the conveyer belt 5.

In the process of actually baking the blades, the blades are placed on the conveyor belt 5 and conveyed upwards, and the conveying claws 6 can prevent the blades from sliding downwards. When the blades are stacked towards one side of the conveying claw 6 due to the action of gravity and the like, the rack 3 rotated above the blades is contacted with the stacked blades, and the teeth 4 on the rack 3 are inserted into the blades and rake the blades in the moving direction of the blades, so that the problem of blade stacking is solved. In the process, because gaps exist among the plurality of teeth 4, the contact area between the side surface of each tooth 4 and the blade is small, and the contact area between the top of each tooth 4 and the blade is small, so that the blade cannot be wound on the rack 3 in the raking process.

It should be noted that: the above description is only the preferred embodiment of the present invention, and the scope of the present invention should not be limited once. Therefore, any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
