[0002] Color sorter / sorting machine is a device that separates materials according to their color through a visual recognition system. Currently, sorting machines on the market can be divided into vertical sorting machines and belt sorting machines according to their structure. In vertical sorting machines, materials enter the sorting box almost vertically through a chute, while in belt sorting machines, materials enter the sorting box horizontally. These two types of sorting machines are suitable for different material scenarios according to their different material entry speeds and angles. Belt sorting machines are fed by belts, which has little wear on the materials and can effectively protect the materials. Vertical sorting machines are fed by chutes, with fast sorting speeds and more stability.

[0003] The existing re-selection sorting machine usually uses a vertical sorting machine or a belt sorting machine to perform sorting operations, and the sorting effect is not ideal. In addition, when sorting materials in practice, it is usually necessary to determine the number of sorting according to the quality of the material itself. For materials that are still unqualified after one re-selection, it is difficult to connect multiple re-selection sorting machines in series in the existing technology. Usually, the materials are poured back into the re-selection sorting machine for sorting, which is very troublesome.

[0004] In view of this, it is particularly important to design and manufacture a composite sorting device which is easy to assemble and can combine a belt sorting machine with a vertical sorting machine for sorting, and has a good sorting effect. Summary of the invention

[0047] The first discharging assembly 180 includes a first discharging rack 181, a first discharging belt 183 and a first driving member 185. The first discharging rack 181 is connected to the bottom of the sorting rack 110. The first discharging belt 183 is movably arranged on the first discharging rack 181. The first driving member 185 is arranged at one end of the first discharging rack 181 and is connected to the first discharging belt 183 in transmission.

[0048] The second discharging assembly 190 includes a second discharging rack 191, a second discharging belt 193 and a second driving member 195. The second discharging rack 191 is connected to the bottom of the sorting rack 110. The second discharging belt 193 is movably arranged on the second discharging belt 193. The second driving member 195 is arranged at one end of the second discharging rack 191 and is arranged on both sides of the sorting rack 110 opposite to the first driving member 185. The second driving member 195 is transmission-connected to the second discharging belt 193.

The first driving member 185 and the second driving member 195 are both driving motors, and are connected to the corresponding transmission rollers through the transmission belts, thereby driving the transmission rollers to rotate, and then driving the first discharging belt 183 or the second discharging belt 193 to move, so as to realize the transmission connection between the first driving member 185 and the first discharging belt 183, and the transmission connection between the second driving member 195 and the second discharging belt 193.

[0050] In this embodiment, a receiving hopper is provided at the end of the first discharging rack 181 in the discharging direction and at the end of the second discharging rack 191 in the discharging direction. The receiving hopper is tilted downward to facilitate material receiving.

[0051] The belt conveyor mechanism 120 includes a conveyor belt 121, a conveyor drive 123 and a mounting base 125. The mounting base 125 is arranged on the top of the frame and is inclined downward.

The conveyor drive 123 is arranged on the mounting base 125 and is transmission-connected to the conveyor belt 121.

[0052] In this embodiment, the mounting base 125 is tilted downward, and the conveying direction of the conveyor belt 121 is tilted upward, so that the material is conveyed from a low place to a high first sorting box 130. This tilted setting can avoid a height difference between two adjacent first sorting boxes 130 when multiple composite sorting devices 100 are connected in series, thereby ensuring the uniformity of the multiple composite sorting devices 100. The serial splicing process is convenient and quick, and the number of composite sorting devices 100 can be increased or decreased on site according to actual production needs.

[0053] In this embodiment, material baffles 127 are further provided on both sides of the conveyor belt 121, and the material baffles 127 are detachably connected to the mounting base 125. The material can be prevented from falling from both sides during the conveying process, so as to ensure that the material reaches the first sorting box 130 safely.

[0054] During the actual sorting process, the material is conveyed to the first sorting box 130 through the belt conveyor mechanism 120 for sorting operation, wherein qualified products fall through the first qualified opening of the first separating hopper 140 and fall into the external discharging device 300 or the belt conveyor mechanism 120 of the next composite sorting device 100, and defective products fall into the trough 160 through the first qualified opening of the first separating hopper 140 and enter the second sorting box 150 through the trough 160 for secondary sorting. The qualified products that mistakenly enter the defective products after the first sorting can be removed and accepted again, thereby ensuring the final sorting accuracy and improving the sorting effect.

[0055] In this embodiment, the feeding device 200 is connected to the sorting frame 110, and the end of the belt conveyor mechanism 120 away from the first sorting box 130 extends into the feeding device 200 or extends into between the adjacent first sorting box 130 and the second sorting box 150, and the discharging device 300 is arranged in the sorting frame 110 and connected to the first separating hopper 140.

The vibrating feeder 230 is arranged on the top of the feeding frame 210. The feeding frame 210 is connected to the sorting frame 110. The end of the belt conveyor mechanism 120 away from the first sorting box 130 is arranged below the vibrating feeder 230. The vibrating motor 250 is arranged on the vibrating feeder 230.

[0057] In this embodiment, the feed frame 210 is detachably connected to the sorting frame 110 of the first composite sorting device 100, and the height of the feed frame 210 matches the height of the material sorting frame, so that the belt conveyor mechanism 120 on the material sorting frame can be extended to the bottom of the vibrating feed hopper 230. By setting the vibrating feed hopper 230, the material can be evenly dropped on the conveying belt 121 of the belt conveyor mechanism 120, so that the material entering the first sorting box 130 is evenly distributed, which is convenient for sorting operations.

[0058] See also Figures 7 to 9 The discharging device 300 includes a third discharging assembly 310 and a discharging hopper 330. The third discharging assembly 310 is arranged in the sorting frame 110. One end of the discharging hopper 330 is connected to the first qualified opening, and the other end of the discharging hopper 330 is connected to the third discharging assembly 310. The connection structure of the third discharging assembly 310 can refer to the connection structure of the first discharging assembly 180 or the connection structure of the second discharging assembly 190. By arranging the third discharging assembly 310 on the inner side of the sorting frame 110, the occupied space of the entire frame can be reduced, saving space.

[0059] In this embodiment, the third discharging assembly 310 includes a third discharging frame 311, a third discharging belt 313 and a third driving member 315.
