Abstract
Description
Technical Field
[0001] This utility model relates to the field of tobacco storage cabinet technology, and in particular to a storage cabinet material distribution device. Background Technology
[0002] In the tobacco production process, the main method is to mix materials on a large scale in storage tanks to greatly simplify and integrate raw materials from different production areas, grades, and with complex and diverse internal qualities, forming standard units, thereby ensuring the internal quality stability of the formula in application.
[0003] Currently, such as Figure 1 As shown, existing tobacco storage bin spreading devices include a reciprocating spreading cart positioned above the storage bin, and a belt conveyor simultaneously spreads material onto the reciprocating spreading cart. This type of spreading device completes the longitudinal stacking of material using a strip-spreading method. The disadvantage of this commonly used storage bin spreading device is that the material (tobacco leaves) is piled up in a point-like manner on the cross-section of the storage bin. This point-like piling results in a small contact area between the material and each round trip of the reciprocating spreading, which is not conducive to the full and uniform mixing of the material, nor to the mutual penetration of moisture and flavorings between the materials. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a storage tank material distribution device to solve the problem that the point stacking method in the prior art results in a small contact area between materials on each round trip of the reciprocating material distribution vehicle.
[0005] This utility model solves the above-mentioned technical problems through the following technical means: a storage tank material distribution device, including a material distribution trolley for reciprocating material distribution along the length of the storage tank, and an inching trolley for supplying material to the material distribution trolley above the material distribution trolley. The inching trolley reciprocates along a direction perpendicular to the length of the storage tank. A material throwing device is also provided between the output end of the inching trolley and the inlet end of the material distribution trolley. The material throwing device is used to throw material at an oblique angle to the inlet end of the material distribution trolley, so that the material at the outlet end of the material distribution trolley is laid flat in a linear manner on the cross-section of the storage tank.
[0006] Optionally, the material throwing device includes a row of rotating throwing rollers parallel to the length of the storage tank. Several throwing blades are evenly distributed axially on each throwing roller, and the length of each throwing blade decreases linearly from the inlet side to the outlet side of the throwing device. Material is transferred between the throwing blades of adjacent throwing rollers. In areas without throwing blades, the blades begin to fall onto the spreading vehicle. The overall length of the throwing blades decreases linearly from the inlet side to the outlet side of the throwing device, thus enabling the throwing device to throw the material in an oblique line into the width direction of the spreading vehicle.
[0007] Optionally, the throwing rollers are installed at the same height from the inlet side to the outlet side. This ensures that most of the material is transferred within the throwing plate area of adjacent throwing rollers, rather than falling directly onto the material spreading vehicle below.
[0008] Optionally, the normal at the connection point between the material ejector and the outer circle of the material ejector roller is installed at a 60° angle and in the same direction as the rotation of the material ejector roller, so that the material is transferred on adjacent material ejector rollers. This allows the material to detach earlier than material ejector rollers installed perpendicular to the normal, making it easier to transfer to the material ejector roller at the rear end of the transfer direction.
[0009] Optionally, both the material laying vehicle and the inch-moving vehicle are belt conveyors with wheels, and the bottom of the material laying vehicle and the inch-moving vehicle is also provided with guide rails that match their width.
[0010] Optionally, the rotation direction of the throwing roller is the same as the rotation direction of the belt conveyor of the inch car.
[0011] Optionally, one end of the throwing roller is fixedly connected to a toothed pulley, the toothed pulley is engaged with a toothed belt, and the rotation of the toothed belt is driven by a variable frequency electric motor.
[0012] The beneficial effects of this utility model are:
[0013] This invention features a design where the throwing rollers are installed at progressively decreasing heights from the inlet to the outlet, and the throwing plates also progressively decrease in length. Adjacent throwing rollers overlap in the vertical projection direction. Furthermore, because the normal to the connection point between the throwing plate and the outer circle of the throwing roller is installed at a 60° angle and in the same direction as the rotation of the throwing roller, the material is prematurely separated from the throwing plate and transferred to the throwing roller at the rear end of the transfer direction. This ensures that the material is transferred along adjacent throwing rollers, resulting in the outlet of the throwing device discharging material in a diagonal line towards the width of the spreading trolley. The movement of the spreading trolley then causes the material to be evenly distributed in a planar shape and fall into the bottom of the storage tank. Compared to traditional point-stacking methods, this method ensures more thorough and uniform mixing of the material. Attached Figure Description

[0023] like Figures 2-6 As shown, this utility model discloses a material distribution device for a storage tank. It includes a material spreading cart 2 for reciprocating material spreading along the length of the storage tank 1. Above the material spreading cart 2 is a moving cart 5 for supplying material to it. The moving cart 5 reciprocates perpendicular to the length of the storage tank 1. This arrangement allows the moving cart to transport a fixed quantity of material 6 in a single round trip, facilitating accurate monitoring of production materials. A throwing device 7 is also provided between the output end of the moving cart 5 and the inlet end of the material spreading cart 2. The throwing device 7 throws material at an angle towards the inlet end of the material spreading cart 2, causing the material 6 at the outlet end of the material spreading cart 2 to be laid out linearly and evenly on the cross-section of the storage tank 1. Specifically, through the throwing device 7, the material flakes falling into the material spreading cart 2 are changed from a traditional point-like drop to an angled drop along the width of the material spreading cart 2. Furthermore, the movement of the material spreading cart 2 causes the material flakes to fall onto the bottom strip of the storage tank, changing from a linear distribution to a uniform planar distribution.
[0024] In this embodiment, the material throwing device 7 includes a row of rotating material throwing rollers 71 parallel to the length direction of the storage tank 1. Several material throwing plates 72 are evenly distributed along the axial direction on the material throwing rollers 71, and the length of the material throwing plates 72 decreases linearly from the inlet side to the outlet side of the material throwing device 7, so that the outlet end of the material throwing device 7 discharges material in an oblique line towards the width direction of the material spreading vehicle 2.
[0025] In this embodiment, to further ensure the material is transferred on the throwing disc 72, due to the limited equipment space, the throwing rollers 71 are set at the same height from the inlet side to the outlet side. The throwing disc 72 is installed at a 60° angle to the normal at the connection point of the outer circle of the throwing roller 71, and is in the same direction as the rotation direction of the throwing roller 71. This allows the material 6 to detach earlier than the throwing disc installed perpendicular to the normal, and thus be transferred to the throwing roller 71 at the rear end of the transfer direction (between the areas where there are throwing discs 72 on adjacent throwing rollers). This arrangement ensures that most of the material is transferred on the throwing disc area of the adjacent throwing rollers, rather than falling directly to the material spreading cart below. The remaining small portion of the material is evenly thrown by the throwing disc 72 onto the material spreading cart 2 below the corresponding throwing roller 71.
[0026] In this embodiment, both the material spreading car 2 and the inch-moving car 5 are belt conveyors with walking wheels 3. The bottom of the material spreading car 2 and the inch-moving car 5 is also provided with guide rails 4 that match their width. The inch-moving car 5 is used to supply material to the throwing device 7. The throwing device 7 throws the material 6 into the width direction of the material spreading car 2 in an oblique line. Then, through the movement of the material spreading car 2, the material 6 smoke sheets are evenly distributed in a planar shape and fall into the bottom belt of the storage tank.
[0027] In this embodiment, the rotation direction of the throwing roller 71 is the same as that of the belt conveyor of the inching vehicle 5. A toothed pulley is fixedly connected to one end of the throwing roller 71, and a toothed belt is engaged with the toothed pulley. The rotation of the toothed belt is driven by a frequency converter electric motor. The existing technologies for transmission and control, such as the belt conveyor, toothed pulley, toothed belt, and motor, will not be described in detail in this embodiment.
[0028] The working principle of this utility model is as follows:
[0029] When the storage tank material distribution device of this utility model is in use, the inching trolley 5 is used to reciprocate to feed the material throwing device 7 in a quantitative manner. The material throwing device 7 throws the material 6 into the width direction of the material spreading trolley 2 in an oblique line shape. Then, through the movement of the material spreading trolley 2, the material 6 smoke sheets are evenly distributed in a planar shape and fall into the bottom strip of the storage tank.
[0030] In this process, the throwing rollers 71 are installed at the same height from the inlet side to the outlet side to save equipment space. The length of the throwing plates 72 decreases sequentially. At the same time, since the normal of the connection between the throwing plates 72 and the outer circle of the throwing rollers 71 is installed at a 60° angle and in the same direction as the rotation of the throwing rollers 71, the material 6 is separated earlier than the throwing plates installed perpendicular to the normal and transferred to the throwing rollers 71 at the rear end of the transfer direction. This allows the material 6 to be transferred on adjacent throwing rollers 71, so that the throwing device 7 throws most of the material 6 into the width direction of the spreading cart 2 in an oblique line, while the remaining small part of the material is also evenly scattered by the throwing plates 72 onto the spreading cart 2 below the throwing rollers 71.
[0031] This invention's material feeding device improves the uniformity of material batches and brand components, completely solving the problem of poor mixing uniformity caused by longitudinally stacked tobacco sheets. This results in more uniform tobacco sheet mixing, more stable product quality, and compliance with brand design requirements. Simultaneously, it facilitates the balancing of temperature and moisture among different varieties and grades of tobacco leaves (shreds), improving the processing resistance of the tobacco sheets and meeting the requirements of high-quality, low-consumption cigarette production.
[0032] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
