[0025] Unless otherwise clearly specified and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0026] Please refer to Figure 1 and Figure 2, a high-precision food color sorter provided by the present invention, includes a frame 1. A material trough 2 is provided at the upper part of the frame 1. A plurality of feeding ports 3 are sequentially provided below the material trough 2. A feeding mechanism 4 is provided below the feeding ports 3. A material arranging mechanism is provided above the feeding mechanism 4. A dust cleaning mechanism 5 is provided in front of the material arranging mechanism. A chute 6 is provided below the feeding mechanism 4. The feeding end of the chute 6 is docked with the feeding mechanism 4, and the discharging end is connected with a discharging port 7. An optical sorting box 8 is arranged on the chute 6, and a sorting mechanism 9 is arranged inside it. After the material enters the material trough 2, it is distributed to each feeding mechanism 4 through the feeding ports 3. The feeding mechanism 4 sequentially transports the material to the material arranging mechanism and the dust cleaning mechanism 5 for material arranging and cleaning, and then transports the material to the chute 6. The material flows down from the chute 6, and after being detected by the optical sorting box 8, the sorting mechanism 9 sorts it according to color and discharges it to different discharging ports 7.

[0027] Specifically, the material trough 2 is a strip-shaped trough. The strip-shaped trough includes a bottom plate 21. First side plates 22 are provided on both sides of the bottom plate 21, and a baffle 23 is provided at the end. A second side plate 24 is connected above the first side plates 22. Both the first side plates 22 and the second side plate 24 are inclined, and the second side plate 24 is an arc-shaped plate. A blanking hole is provided on the bottom plate 21. The blanking hole is used to put the material stored in the material trough 2 into the feeding port 3 located below it.

[0028] Please refer to Figure 2 and Figure 3 , the feeding port 3 includes a material receiving port 31. The cross-sectional area of the material receiving port 31 gradually decreases from top to bottom. A discharging port 32 is connected below the material receiving port 31. The discharging port 32 is a flat port, and its length direction intersects with the feeding direction of the feeding mechanism 4. As the feeding mechanism 4 moves, the material can be evenly laid on the feeding mechanism 4, preparing for the next cleaning and color sorting of the material.

[0029] The feeding mechanism 4 is arranged below the feeding port 3, and includes a housing 41. Both sides of the housing 41 are fixed on the frame 1. Its front end and top are open, and the rear end is a closed end. A plurality of partition plates 42 are sequentially arranged in the housing 41. The partition plates 42 divide it into a plurality of installation slots.

[0030] A conveyor belt mechanism 43 is arranged in the installation slot. The rear end of the conveyor belt mechanism 43 is in contact with the inner wall of the housing 41, and the front end is docked with the feeding end of the chute 6. The front end of the conveyor belt mechanism 43 is placed above the chute 6. After the material is sent out from the front end of the conveyor belt mechanism 43, it falls onto the chute 6 and slides down along the chute 6.

[0031] The conveyor belt mechanism 43 includes a driving roller, a driven roller and a conveyor belt. Both ends of the driving roller and the driven roller are rotatably arranged on the partition plates 42 or the inner wall of the installation slot. The driving roller rotates under the drive of a driving motor, thereby driving the driven roller to rotate and making the conveyor belt move to transport the material.

[0032] The material feeding mechanism includes a mounting bracket 10, on which a scraping plate 11 is provided. The scraping plate 11 faces the conveyor belt, levels the materials on the conveyor belt, and restricts the throughput of the materials.

[0033] Specifically, notches are formed on both sides of the scraping plate 11, and the mounting bracket 10 is fixed in the notches and is detachably connected to the side wall of the housing 41 through a clamp. There is a certain distance between the lower part of the scraping plate 11 and the surface of the conveyor belt, and the size of this distance is adjusted adaptively according to the size of the material particles.

[0034] The lower edge of the scraping plate 11 is provided with bristles 12. The length of the bristles 12 is 1 - 3 cm, and their hardness is B - 09. During the movement of the materials, the bristles 12 can better brush the material particles evenly, make the material particles evenly laid on the surface of the conveyor belt. In addition, it can prevent the scraping plate 11 from getting stuck or worn, and can also protect the surface of the materials from being worn.

[0035] The dust cleaning mechanism 5 is arranged above the conveyor belt 43 and is used to clean the dust on the surface of the material particles on the conveyor belt and the dust mixed in the material particles.

[0036] Please refer to Figure 4 , the dust cleaning mechanism 5 includes a panel 51. The lower surface of the panel 51 is provided with a first flexible rubbing surface 52, and a plurality of first flexible protrusions 53 are provided on the surface of the first flexible rubbing surface 52. The panel 51 is arranged above the conveyor belt, and the first flexible rubbing surface 52 is in contact with the conveyor belt.

[0037] The surface of the conveyor belt should have appropriate friction, which can keep the material particles moving with the conveyor belt and will not be unable to move forward due to the friction of the first flexible protrusions 53. To solve this technical problem, a second flexible rubbing surface 54 is provided on the surface of the conveyor belt. A plurality of second flexible protrusions 55 are provided on the surface of the second flexible rubbing surface 54, and the second flexible rubbing surface 54 is in contact with the first flexible rubbing surface 52.

[0038] During use, when the material particles are put on the surface of the conveyor belt from the feed inlet 3, the dust mixed in them enters between the second flexible protrusions 55. When the material particles enter the position of the dust cleaning mechanism 5, the first flexible rubbing surface 52 and the second flexible rubbing surface 54 rub them together to remove the dust stained on their surfaces. Since the second flexible protrusions 55 restrict the movement of the material particles, the position movement of the material particles is small, and they can still be relatively evenly laid on the conveyor belt and move forward with the conveyor belt. And when the materials move to the end of the conveyor belt, due to the arc at the front end of the conveyor belt, the distance between the ends of adjacent second flexible protrusions 55 can be slightly enlarged, ensuring that all the material particles fall into the chute 6.

[0039] To prevent foreign dust from mixing in, the size of the bottom of the second flexible protrusion 55 can be increased according to actual needs to reduce the expanded distance between adjacent second flexible protrusions 55, ensuring that the foreign dust always remains in the conveyor belt. After using for a period of time, the foreign dust can be removed by a vacuum cleaner to ensure the dust removal effect.

[0040] Please refer to Figure 2 , the optical sorting box 8 includes a box body 81, an optical color sorting lens 82 is provided in the box body 81, and a plurality of discharge ports 7 are sequentially provided below the color sorting lens 82. The optical color sorting lens 82 performs color sorting and identification on the materials delivered by the chute 6. A sorting mechanism 9 is provided above the discharge port 7. The sorting mechanism 9 puts the corresponding material particles into the corresponding discharge port 7 according to the color sorting result. The optical color sorting lens 82 and the sorting mechanism 9 are both prior arts, so their detailed structures will not be described in detail.

[0041] An auxiliary dust removal mechanism (not shown in the figure) is further provided on one side of the optical sorting box 8. The auxiliary dust removal mechanism is a vacuum cleaner, which removes the remaining foreign dust in the optical sorting box 8 to further improve the accuracy of color sorting. The vacuum cleaner is a vacuum cleaner of the prior art, so its detailed structure will not be described in detail.

[0042] Working principle:

[0043] After the materials enter the material trough 2, they are distributed to each feeding mechanism 4 through the feeding port 3. The feeding mechanism 4 sequentially transports the materials to the material sorting mechanism and the dust cleaning mechanism 5 for material sorting and cleaning, and then transports the materials to the chute 6. The materials flow down from the chute 6, and after being detected by the optical sorting box 8, the sorting mechanism 9 distributes them to different discharge ports 7 for discharging according to the color.

[0044] The above content is a further detailed description of the present invention in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention belongs, without departing from the concept of the present invention, several simple deductions or replacements can still be made, which should all be regarded as belonging to the protection scope of the present invention.
