Description

Technical Field

[0001] This utility model relates to the field of tobacco product manufacturing technology, specifically to a material feeding roller for a tobacco elevator used for loose materials. Background Technology

[0002] A tobacco elevator is a lifting device used in the tobacco industry. It adopts the bucket elevator principle, using chains and buckets to lift tobacco materials from a low position to a high position, thereby realizing the transportation of tobacco materials. It has the advantages of high efficiency, stability and safety, and is widely used in the tobacco transportation field.

[0003] The feeding roller is a crucial component of the tobacco elevator. Working in conjunction with the conveyor belt, the roller's rotation transforms the material from a compacted to a loose state, preventing blockages and ensuring a uniform and smooth quantitative flow of material into the conveying system. Existing feeding rollers are circular rollers with evenly distributed teeth on their surface, which can achieve a certain degree of material loosening and uniformity. However, problems such as material entanglement and jamming still occasionally occur, preventing material from entering the conveying system normally and even causing production line shutdowns, directly impacting production efficiency and continuity.

[0004] This invention provides a feeding roller for a tobacco elevator to avoid the shortcomings of the prior art.

[0005] This utility model adopts the following technical solution to solve the technical problem: a feeding roller for a tobacco elevator, wherein the conveyor belt is inclined upward from the front end to the rear end, and steel nails are arranged in rows at equal intervals perpendicular to the conveying direction on the belt; the feeding roller is located above the conveyor belt and is rotatably mounted on the frame, forming a rotating pair around its own axis with the frame, one end of which is connected to the drive motor shaft; multiple radially outwardly radiating roller fins are evenly distributed along the outer edge of the feeding roller, the length of the roller fins is the same as the length of the feeding roller, and their outer ends are folded into serrations opposite to the rotation direction of the feeding roller; a gap is left between the feeding roller and the conveyor belt just enough for the roller fins, the serrations and the material to pass through.

[0006] In actual setup, the feeding roller preferably has four roller fins evenly distributed along the circumference, and the roller fins are welded and fixed to the outer edge of the feeding roller.

[0007] Furthermore, a pair of frame plates are provided as the frame;

[0008] Both ends of the feeding roller are rotatably connected to a pair of frame plates via bearings, and each end passes through a corresponding frame plate and is shaft-connected to the drive motor.

[0009] Furthermore, the drive motor is installed and fixed to the frame plate via a support plate fixed to the outside of the frame plate.

[0018] This utility model provides a feeding roller for a tobacco elevator, which has the following beneficial effects:

[0019] 1. The multiple roller fins and serrations evenly distributed around the outer edge of the material-distributing roller of this utility model can loosen clumps of material when the conveyor belt lifts the material, or push some material off the conveyor belt when the conveying flow is too large, so that the material is evenly and appropriately dispersed on the conveyor belt and smoothly fed into the conveying system. It has a good material-distributing effect, can effectively avoid local accumulation and overload of material, and prevent material conveying blockage. It is especially suitable for materials that are prone to entanglement.

[0020] 2. The solid layer inside the inner layer of the feeding roller and the reinforcing component between the inner and outer layers of this utility model improve the structural strength of the feeding roller, which is conducive to improving the working stability of the feeding roller and extending its service life.

[0021] 3.

[0028] A type of feeding roller for a tobacco elevator, such as Figs. 1-3 As shown, its structural relationship is as follows: the conveyor belt 2 is inclined upward from the front end to the rear end, and steel nails 3 are arranged in rows at equal intervals perpendicular to its conveying direction.

[0029] The feeding roller 6 is located above the conveyor belt 2. Both ends are rotatably connected to a pair of side plates 1 via bearings, and each end passes through a corresponding side plate 1 and is connected to the drive motor shaft. Four roller fins 7 are evenly welded around the outer edge of the feeding roller 6. The length of the roller fins 7 is the same as the length of the feeding roller 6, and their outer ends are folded into saw teeth 8 opposite to the rotation direction of the feeding roller 6. A gap is left between the feeding roller 6 and the conveyor belt 2 to allow the feeding roller fins 7, saw teeth 8 and material to pass through.

[0030] The feeding roller 6 includes a solid steel tube and a hollow steel tube coaxially sleeved outside the solid steel tube. Reinforcing components are evenly distributed and supported between the solid steel tube and the hollow steel tube along the circumference. The reinforcing components are a pair of cross-arranged reinforcing rods 13. The hollow steel tube is covered with a water-proof layer, and the water-proof layer is covered with a wear-resistant layer.

[0031] A pair of side panels 1 are respectively attached to the conveyor belt 2 and set on both sides of the conveyor belt 2. The drive motor is installed and fixed to the side panels 1 through the support plate 4 fixed on the outside of the side panels 1.

[0032] When using the above-mentioned tobacco elevator feed roller to lift materials, the following process is included:

[0033] The material is placed on the surface of conveyor belt 2 and is lifted upwards at an incline along conveyor belt 2 under its action. At the same time, the drive motor drives the material-pushing roller 6 to rotate around its own axis, and drives the material roller fins 7 and saw teeth 8 on the material-pushing roller 6 to rotate synchronously. When the material is conveyed between conveyor belt 2 and material-pushing roller 6, it is loosened by the action of saw teeth 8 and material roller fins 7, and evenly dispersed on conveyor belt 2, and then sent to the conveying system by conveyor belt 2.
