Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of material dividing devices, and in particular relates to an electric roller material dividing device. Background Art
[0002] As an important impurity removal equipment in the leaf threshing and re-drying line, the air separation impurity remover plays a vital role in removing light debris, such as chicken feathers, plastic film, and hemp fibers. The quality of the impurity removal directly affects the overall product quality indicators.
[0003] In order to further improve the efficiency of wind selection and impurity removal, on-site operators will adjust the wind selection frequency according to different grades of tobacco leaves. If the wind selection frequency is adjusted too large, the impurity sorting effect will be good, but the amount of tobacco leaves sorted will increase accordingly. On the contrary, if the sorted material is small, the impurities will also decrease. Too much material selected by wind increases the difficulty of selection for the impurity selectors, especially when there are large pieces of tobacco leaves and broken tobacco leaves on the impurity selection belt at the same time, it is more difficult to select the impurities, and due to the obstruction of large pieces of tobacco leaves during operation, the impurities under the large pieces of tobacco leaves cannot be removed by the electrostatic belt, which seriously affects the electrostatic impurity removal effect.
[0004] It is very difficult to adjust the gap between rollers in traditional chain-driven rotary roller feeders, and the gap cannot be adjusted accurately due to the tension and pitch of the chain, and the real-time adjustment function cannot be achieved during the operation of the equipment. Traditional vibrating mesh screening machines are also troublesome to replace the screen and cannot be adjusted in real time. Since the screening mode is a vibrating reciprocating screening mode, the movement mode of tobacco leaves on the surface of the screen cannot be achieved, resulting in poor screening effect, and it is impossible to separate debris from large and extra-large tobacco leaves during the screening process.
[0005] In view of this, in order to optimize and solve the above-mentioned problems, the utility model intends to install an electric roller dividing device under the hopper of the wind separation and impurity sorting discharge belt, which is used to separate oversized pieces, large and medium tobacco leaves, broken tobacco leaves and debris, reduce the amount of tobacco leaves entering the electrostatic impurity removal and impurity sorting belts, reduce the difficulty of impurity sorting for sorting personnel, and improve the impurity sorting efficiency. Summary of the invention
[0006] The utility model provides an electric roller material separation device for separating oversized tobacco leaves, large and medium tobacco leaves, broken tobacco leaves and debris, reducing the amount of tobacco leaves entering the electrostatic impurity removal and impurity selection belt, reducing the difficulty of impurity selection for impurity selection personnel, and improving impurity selection efficiency. The specific scheme is as follows:
[0007] A motorized roller material dividing device, wherein a material dropping hopper is provided above the material dividing device, a large piece collecting device is provided on one side below the material dividing device, and a debris collecting device is provided on the other side. The characteristic is that the material dividing device comprises two mounting bases arranged opposite to each other and a plurality of motorized rollers evenly spaced between the two mounting bases, a transverse through groove is provided in the middle of the two mounting bases, a slide groove seat is provided on the outer side of the through groove, both ends of the motorized roller are fixed on the slide groove seat by fixing parts, both ends of the motorized rollers are clamped in the two through grooves, a plurality of extraction teeth are evenly spaced along the circumference of the motorized roller along its length direction, and the extraction teeth on the two adjacent motorized rollers are staggered.
[0008] Furthermore, the electric roller is provided with a long strip of healthy teeth along its length direction, a plurality of tooth rings are sleeved on the electric roller at intervals, a key groove suitable for the healthy teeth is opened on the inner side of the tooth ring, a plurality of extraction teeth are sleeved on the outer circumference of the tooth ring, a sleeve is sleeved on the electric roller between the tooth rings, and the end of the electric roller is locked and fixed by a locking nut and a thrust washer.
[0009] Furthermore, a brush strip covering the through groove is provided on the upper side of the slide groove seat.
[0010] Furthermore, the brush strip is made of plant brown hair.
[0011] Furthermore, a scale is horizontally provided on the mounting base at the lower side of the slide seat.
[0012] Furthermore, a material guide plate is provided on the top of the mounting base.
[0013] The beneficial effects of the utility model are:
[0014] 1. Compared with traditional vibrating screening machines and chain-driven screening machines, this device has a simpler structure, lower cost, more stable operation, and smaller footprint. It is not limited by the installation space of on-site equipment and can be installed arbitrarily under the belt conveyor.
[0015] 2. The speed and direction of each electric roller can be adjusted at any time. The speed of the electric roller can be adjusted at any time according to different flow rates, and the movement time of tobacco leaves on the roller can be controlled to achieve the best material distribution effect.
[0016] 3. Compared with chain-driven classifiers and mesh-type vibrating screeners, the spacing between each electric roller can be easily adjusted according to the different characteristics of tobacco leaves to ensure a more targeted sorting effect.
[0017] 4. Compared with the mesh-type vibrating screening machine, the material screening mode is changed. The material is divided by reciprocating vibration instead of turning. During the turning process of the material, the fragments, small pieces and most of the debris smaller than the gap between the teeth are separated and fall onto the debris belt, finally separating the oversized pieces, large pieces from small pieces, fragments and debris and sending them to different belts respectively.
