Description

Technical Field

[0001] The utility model belongs to the technical field of color sorters, in particular to a material leveling plate and a color sorter. Background Art

[0002] When using a color sorter to sort materials, in order to ensure that abnormal points in the product can be found through optical recognition technology, the product is usually controlled to enter the field of view of the color sorter in a single layer or a single particle. Therefore, before entering the sorting box for color sorting and identification, the product needs to be evenly distributed in a single layer; color sorters generally feed at a certain angle, and the material moves through the sorting box by gravity. Therefore, it is generally necessary to evenly distribute the product on the inclined slide of the product feed.

[0003] The invention patent application with publication number CN1733370A discloses a ramp for a sorting and inspection device, including a first part at the top and a slotted part at the bottom, wherein the slotted part has a plurality of grooves along the direction of movement, and the material moves along the grooves in the slotted part to avoid lateral interference between the materials, so that the materials form a plurality of queues and enter a color sorter for identification and sorting; wherein the first part at the top has a smooth surface.

[0004] In the above scheme, although the material can be stably discharged in the second part, the material falls freely in the first part, and the material is easy to gather together, resulting in more material in some grooves and less material in other grooves; and when the material enters the groove, it will pile up and queue up, and move and squeeze towards the groove next to it, causing the material to collide, which is easy to cause material jumping and collision damage. Moreover, in the subsequent color sorting, the nozzle working frequency corresponding to the groove with more material is higher, and the nozzle starting frequency corresponding to the position with less material is relatively low, resulting in different nozzle lifespans at different positions. Regular and unified replacement of nozzles will cause some nozzles to be wasted, and if a failure occurs and they are replaced and repaired, it will cause frequent downtime, affecting production.

[0005] Please also refer to Figure 1In the prior art shown, the material falls into the slideway below the opening side through vibration in the vibrating hopper 01, and a bending protrusion and a material blocking column 07 are set on the first section of the slideway pad 05 to separate the agglomerated wet materials from each other. In actual use, the vibrating hopper 01 needs to be provided with materials through the upper feeding mechanism. When the material falls into the vibrating hopper 01, since vertical baffles are respectively set on the three sides of the vibrating hopper 01, the material will fall into the vibrating hopper 01 through the limiting structure when it falls. Under the shielding effect of the falling parabola and the vertical baffles, the material at the edge position close to the vertical baffle will be significantly less than the middle position. Although the vibrating hopper 01 can disperse the material to a certain extent, it still cannot provide enough material for the edge position in actual use. After the material gathers in the middle area, in order to make the material meet the requirements of single-layer material discharge, the feeding speed of the vibrating hopper will be reduced to avoid the accumulation of the material when entering the groove of the second part, thereby causing the design capacity of the color sorter to be unable to be fully utilized, affecting the product output.

[0006] Although the scheme is designed with bending protrusions and material retaining columns to promote uniform distribution of materials, the bending protrusions mainly disperse the materials through the bouncing effect of the materials and cannot guide the materials to be distributed to the two sides of the slide pad 05. The material retaining columns will close part of the outlet space, causing material accumulation, which will in turn aggravate material accumulation and affect production capacity. Utility Model Content

[0007] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model provides a material leveling plate and a color sorter, which can evenly distribute the materials in the horizontal space during the sliding process.

[0009] When the material on the surface of the material leveling plate passes through the material guide part, it can move to at least one side of the material guide part under the guidance of the material guide part to change the falling direction. The material sliding down between two adjacent material guide parts will not change its direction itself, but can change its movement direction under the collision of the material that changes its direction after passing through the material guide part. At the same time, some materials will directly cross the material guide part without basically changing their sliding direction. These materials may change their original movement direction and separate from each other or maintain their original movement direction when returning to the material leveling plate, but this movement state will also be changed by the materials next to them that change their movement direction under the action of the material guide part, and finally most of the materials on the material leveling plate will produce lateral deviation movement. After adjustment of at least two rows of the material guide parts, the materials on the material leveling plate will change their lateral movement direction multiple times to achieve uniform distribution; make full use of the lateral conveying space, reduce material accumulation, increase the feeding speed, make full use of the theoretical production capacity of the color sorter, and increase output.

[0018] Preferably, the apex of the depression of the material guiding portion is connected to the protrusion at the lower end of the material guiding portion to form a convex ridge between the two sides.

[0019] Preferably, the material leveling plate is provided with at least one row of dispersing parts before the material guiding part, and the material passes through the dispersing parts to generate a loosening and dispersing movement;

[0020] The dispersing portion includes convex and / or concave structures that are continuously and / or spaced apart along the width direction of the material leveling plate.

[0022] Preferably, the upper end of the material leveling plate includes a hook for installing the material leveling plate, and both sides of the material leveling plate have upper flanges respectively.

[0023] The utility model also provides a color sorter using the material leveling plate for feeding.

[0024] The advantages of the material leveling plate and color sorter provided by the utility model are that when the material on the surface of the material leveling plate passes through the material guide part, it can move to at least one side of the material guide part under the guidance of the material guide part to change the falling direction. The material sliding down between two adjacent material guide parts will not change its direction itself, but can change its movement direction under the collision of the material that changes its direction after passing through the material guide part. At the same time, some materials will directly cross the material guide part without basically changing their sliding direction. These materials may change their original movement direction and separate from each other or maintain their original movement direction when returning to the material leveling plate, but this movement state will also be changed by the materials next to them that change their movement direction under the action of the material guide part, and finally most of the materials on the material leveling plate will produce lateral deviation movement. After being adjusted by at least two rows of the material guide parts, the materials on the material leveling plate will change their lateral movement direction multiple times to achieve uniform distribution; the lateral conveying space is fully utilized to reduce material accumulation, increase the feeding speed, and fully utilize the theoretical production capacity of the color sorter to increase output.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0040] The terms "first", "second", etc. in the specification and claims of the present utility model are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0041] Example 1

[0042] refer to Figure 1 This embodiment provides a material leveling plate, including at least two rows of multiple material guide parts 1 distributed at intervals. The material can move along the inclined material leveling plate, at least part of the material passing through the material guide part 1 can disperse and move to at least one side of the material guide part 1, and the other part of the material passing through the material guide part 1 can pass over the material guide part 1.

[0043] The material shaving plate provided in this embodiment is provided with multiple rows of guide portions 1 along the width direction of its surface (i.e., the direction perpendicular to the movement of the material), and the multiple guide portions 1 in each row are arranged at intervals. When the material on the surface of the material shaving plate passes through the guide portion 1, it can move to at least one side of the guide portion 1 under the guidance of the guide portion 1 to change the falling direction. The material sliding down between two adjacent guide portions 1 will not change its direction itself, but can change its movement direction under the collision of the material that changes its direction after passing through the guide portion 1. At the same time, some materials will directly pass over the guide portion without basically changing the sliding direction. Material part 1, this part of the material may change the original movement direction and separate from each other or maintain the original movement direction when returning to the surface of the material leveling plate, but this movement state will also be changed by the material next to it that changes the movement direction under the action of the material guide part 1, and finally most of the material on the material leveling plate will produce lateral deviation movement. After adjustment of at least two rows of the material guide parts 1, the material will change the lateral movement direction on the material leveling plate for many times to achieve uniform distribution; make full use of the lateral conveying space, reduce material accumulation, increase the feeding speed, make full use of the theoretical capacity of the color sorter, and increase production.

[0044] Since the material tends to gather in the middle of the material leveling plate and there is less material on both sides, the material guide portion 1 in the middle part preferably disperses the material to both sides, while the material guide portion 1 at the edge can be set to guide and disperse the material passing through it only to one side of the edge, thereby increasing the amount of material flowing from the edge for subsequent operations.

[0045] Although the material leveling plate provided in this embodiment is an improvement proposed to address the problems of the feeding structure of a color sorter, its usage scenario is not limited to the field of color sorters. For example, the material leveling plate provided in this embodiment can be selected for all scenarios where materials need to be evenly distributed and fed at an angle.

[0046] The number of rows of the material guide 1 can be adaptively designed according to the type of material and the original distribution of the specific material. For example, for granular materials such as rice, millet, soybeans, and wheat, since they are prone to rolling, after passing through the material guide 1, the mutual contact between the materials increases, and the change of the motion state increases. Therefore, through the transmission of the motion state, all materials can quickly contact and collide with each other during the sliding process to finally achieve uniform distribution as a whole. Therefore, the required structure of the material guide 1 can be set less. For the transportation of materials such as tea, the motion transmission effect between materials is poor, and it mainly depends on the material guide 1 to change the distribution of the material. Therefore, it is necessary to set the material guide 1 with a larger number of rows. The specific number of settings can be determined by experimental adjustment according to actual conditions.

[0047] In some embodiments, two adjacent rows of the material guide portions 1 are staggered, or at least two adjacent rows of the material guide portions 1 are staggered in some positions, so that the material sliding down between two adjacent material guide portions 1 in the same row can be guided by the lower material guide portion 1 to perform a dispersed movement, so as to achieve a better material mixing effect.

[0048] refer to Figure 3 In this embodiment, the guide portion 1 is protruding relative to the surface of the material leveling plate, and the protruding apex 11 of the guide portion 1 smoothly transitions to the two sides of the guide portion 1 and falls back to the surface of the material leveling plate, so that the material moving through the guide portion 1 can naturally slide down along the connecting surface between the guide portion 1 and the two sides to produce lateral movement, changing the sliding direction of the material. At the same time, some materials will directly cross the guide portion 1 without sliding down and continue to be transmitted downward. The protruding apex 11 of the guide portion 1 can be only an end point, or it can be set as a protruding segment line, or the guide portion 1 can be formed into a table-like structure relative to the protruding plane of the material leveling plate. For example, the guide portion 1 can select structures such as a truncated cone, a prism, a pyramid, and a cone.

[0049] Combination Figure 4 and Figure 5In some embodiments, the material guide portion 1 is expanded to both sides at the front end of the material leveling plate to form a guide section 12 for dispersing the material to both sides, and the front end of the material guide portion 1 gradually transitions from a smooth bulge on the surface of the material leveling plate to the protruding vertex 11. The specific shape of the material guide portion 1 (projected shape on the surface of the material leveling plate) can be a regular shape such as a triangle, trapezoid, rhombus, circle, semicircle, ellipse, etc., or it can be a special shape that is appropriately deformed on the basis of meeting the above conditions.

[0050] The side projection structure of the material guide portion 1 in some embodiments is as follows: Figure 6 As shown, the smooth transition from the front end of the guide portion 1 to the position of the protruding apex 11 can be an inclined transition or an arc transition, or some sections use an inclined transition and some sections use an arc transition; the lower end of the guide portion 1 has a step structure formed by a drop to transition to the surface of the material leveling plate, or is smoothly connected to the surface of the material leveling plate, and the specific smooth connection method can be the same as or different from the connection method at the upper end.

[0051] When the lower end of the guide portion 1 adopts a step structure transition, the separation of materials can be further increased and the effect of uniform material can be achieved more quickly, but there may be certain damage to the material during the bouncing process, which increases the defective rate; if a smooth transition is used, the guide section can be set to allow the material to naturally separate. Although the effect of uniform material is not obvious enough, it is sufficient to set up a sufficient number of rows of the guide portion 1, and the loss during the guiding process can be reduced, thereby increasing the output.

[0052] In some embodiments, the slope from the front end of the guide portion 1 to the protruding apex 11 is smaller than the slope from the two sides of the guide portion 1 to the protruding apex 11. For a regular structure, the longitudinal dimension is generally longer than the transverse dimension. During the material sliding down, the smaller the slope from the front end to the protruding apex 11, the smaller the obstruction to the material movement, thereby reducing the impact on the normal falling process and falling speed of the material. At the same time, there is a longer guide section 12 for the material to change its motion state, which has a better guiding effect on the material. The above effect can also be achieved by eccentrically setting the position of the protruding apex 11.

[0053] refer to Figure 7 In some embodiments, the slope of the guide section 12 of the material guide portion 1 on both sides of the material leveling plate close to the side of the material leveling plate is smaller than the slope of the guide section 12 away from the side, thereby reducing the difficulty of the material moving to the edge of the material leveling plate and increasing the amount of material transported at the edge.

[0054] refer to Figure 8In some embodiments, the material guide portion 1 is a triangular structure and is distributed all over the surface of the material leveling plate. The positions of two adjacent rows of the material guide portions 1 are staggered to adjust the direction of the material transported by the material leveling plate to achieve uniform feeding. Upper flanges 3 are provided on both sides of the material leveling plate to prevent the material from being blocked in the gaps on both sides of the material leveling plate. The material leveling plate can be fixed by bolts, welding, etc. In some embodiments, a hook 4 is formed by bending upward and backward on the material leveling plate. The hook is hung on the supporting structure to facilitate the installation of the material leveling plate and facilitate disassembly and maintenance.

[0055] Example 2

[0056] refer to Fig. 9 The material leveling plate provided in this embodiment is different from that in Embodiment 1 in that the material guide portion 1 is recessed relative to the surface of the material leveling plate, and the recessed apex 21 of the material guide portion 1 smoothly transitions to both sides of the material guide portion 1 and is connected to the surface of the material leveling plate.

[0057] The material leveling plate provided in this embodiment is provided with the guide portion 1 sunken on the surface. After the material passes through the area of ​​the guide portion 1, it slides down along its edge to the apex 21 of the depression, thereby having a movement speed from the position where the material enters the guide portion 1 to the apex 21 of the depression, and changes the movement state after colliding with other materials in the middle, and finally adjusts the movement direction of the material so that the material has a lateral movement state, thereby adjusting the position of the material in the width direction of the material leveling plate to achieve uniform material discharge. At this time, the guide section 12 should be the transition part between the two sides of the guide portion 1 and the lower end of the guide portion 1.

[0058] The projection shape of the concave material guide portion 1 can be set with reference to the convex material guide portion 1 in Example 1, wherein the downward transition position where the upper end of the concave material guide portion 1 cooperates with the material leveling plate can be set to a step structure or a smooth transition structure, so that the material bounces slightly and further produces a movement trend of separation from each other, and a smooth transition method should be selected at the position where the lower end of the material guide portion 1 cooperates with the material leveling plate to enable the material to climb back to the surface of the material leveling plate.

[0059] refer to Fig.10 In some embodiments, the concave apex 21 of the material guide portion 1 is connected to the lower end protrusion of the material guide portion 1 to form a ridge 22 between the guide sections 12 on both sides, so that the material is guided to both sides for separation, thereby improving the material mixing effect.

[0060] Furthermore, in some embodiments, the material guide portion 1 with a raised configuration provided in Example 1 and the material guide portion 1 with a recessed configuration provided in Example 2 can be combined to design the material distribution portion, and the material can be evenly distributed through a regular or irregular combination of the raised structure and the recessed structure.

[0061] Example 3

[0062] refer to Fig.11 In this embodiment, on the basis of Embodiment 1 and Embodiment 2, a dispersion part 5 is further provided on the material leveling plate. After the material passes through the dispersion part, the material is loosened and dispersed. Specifically, the dispersion part 5 includes a convex or concave structure continuously provided along the width direction of the material leveling plate, or includes a convex or concave structure provided at intervals, or includes both the dispersion part 5 provided continuously and the dispersion part 5 provided at intervals. The dispersion part 5 is similar to the speed bump structure on the road. When the material passes through the dispersion part 5, a small amplitude bounce occurs, so that the materials are loosened due to the mutual aggregation between the materials, which is convenient for guiding the movement in different directions under the action of the subsequent material guide part 1, thereby achieving the material leveling effect. For materials with strong adhesion such as tea leaves, the materials can be loosened and then passed through the material guide part 1 for leveling.

[0063] In some embodiments, at least two rows of the spaced-apart dispersing portions 5 are provided, and the dispersing portions 5 in two adjacent rows are arranged in a staggered manner.
