[0050] Figure 1 is a cross-sectional view of a flakes distributing device according to an exemplary embodiment of the present invention. Figure 2 It is an enlarged view of the first slot according to an exemplary embodiment of the present utility model.

[0051] According to the inventive concept of one aspect of the utility model, Figure 1-Figure 2 As shown, a flaking distribution device is provided, comprising: a support 1, a roller screen 2, a first collecting hopper 301, a second collecting hopper 302, a third collecting hopper 303, a first slot 5, a flap 6 and a first driving device 7. The roller screen 2 is arranged on the upper part of the support 1, and the roller screen 2 comprises at least three areas, a first area 201, a second area 202 and a third area 203. The mesh number of the screen in the first area 201 is smaller than the mesh number of the screen in the second area 202, and the mesh number of the screen in the second area 202 is smaller than the mesh number of the screen in the third area 203. The first collecting hopper 301, the second collecting hopper 302 and the third collecting hopper 303 are respectively arranged below the first area 201, the second area 202 and the third area 203 to collect the first flakes 401, the second flakes 402 and the third flakes 403 respectively, and the sizes of the first flakes 401, the second flakes 402 and the third flakes 403 are reduced in sequence, wherein the first collecting hopper 301, the second collecting hopper 302 and the third collecting hopper 303 are arranged in parallel and adjacently, and a first slot 5 is provided on the common side wall of the first collecting hopper 301 and the second collecting hopper 302. The bottom edge of the flap 6 is rotatably connected to the bottom of the first slot 5. And the first driving device 7 is connected to the flap 6 to drive the top edge of the flap 6 to rotate into the first collecting hopper 301 or the second collecting hopper 302.

[0052] In this embodiment, a slot is opened between the first collecting hopper 301 and the second collecting hopper 302, and a flap 6 is provided. The opening and closing of the flap 6 and the opening angle are controlled by the first driving device 7, so that the first flakes 401 and the second flakes 402 are mixed in proportion without secondary mixing. The collected mixture can be directly used in the production of the next process, which saves production processes and improves production efficiency.

[0053] According to some embodiments of the utility model, the bracket 1 is used to support the roller screen machine 2. Optionally, the bracket can adopt a steel structure, such as a load-bearing frame platform constructed by welding steel sections. The bracket 1 provides a certain height for the roller screen machine 2 to meet its sufficient working space requirements.

[0054] According to some embodiments of the utility model, a gear ring is provided on the outer periphery of the roller screen machine 2 near the third area 203, and a second driving device 204 is provided on the bracket 1. The second driving device 204 is transmission-connected to the gear ring to drive the drum of the roller screen machine 2 to rotate.

[0055] According to some embodiments of the utility model, a feed port 205 is provided at one end of the roller screen machine 2 close to the third area 203, and sieve holes are arranged in an array on the drum of the roller screen machine 2. The drum is divided into three areas according to the mesh number of the sieve holes (sieve hole size). After the flaked mixture prepared by the flaking machine passes through the feed port 205, the mixed flaking materials pass through the third area 203, the second area 202 and the first area 201 in sequence under the action of the rolling of the drum. Since the mesh number of the sieve in the first area 201 is smaller than that of the second area 202, and the mesh number of the sieve in the second area 202 is smaller than that of the third area 203, the flaking can be screened into the third flaking 403 (small size), the second flaking 402 (medium size) and the first flaking 401 (large size) in sequence according to their sizes.

[0056] According to some embodiments of the utility model, when the flakes do not need to be mixed, the flap 6 remains in a vertical state, and the first flakes 401, the second flakes 402 and the third flakes 403 independently enter the first collecting hopper 301, the second collecting hopper 302 and the third collecting hopper 303 respectively and are transported to the corresponding next process or enter the corresponding silo.

[0057] According to some embodiments of the utility model, when the flakes need to be mixed, the flap 6 is opened, and the first flakes 401 or the second flakes 402 enter the second collecting hopper or the first collecting hopper through the first slot 5. Specifically, the flipping direction and flipping angle of the flap 6 are controlled according to the process requirements. For example, if the ratio of large-sized to medium-sized flakes in the mixed flakes required in the next process is 9:1, the first driving device 7 is used to control the flap 6 to rotate clockwise (with a rotation angle of 1:1). Figure 1 The orientation of the structure shown in the figure shall prevail), at this time, the flap 6 is located in the second collecting hopper 302, and part of the second flakes 402 screened and dropped in the second area 202 of the roller screen 2 fall on the flap 6, and slide into the first collecting hopper 301 along the flap 6 to be mixed with the first flakes 401. Optionally, the angle of rotation of the flap is adjusted according to the proportion of large and small sizes in the mixed flakes (it should be noted that the proportion of flakes of various sizes produced by the same batch of materials after planing by the flaker is roughly the same). For example, if it is necessary to continue to increase the proportion of medium sizes, adjust the flap 6 to rotate clockwise again by a certain angle to receive more medium-sized flakes. Further optionally, if the proportion of large and medium sizes in the mixed flakes required in the next process is 1:9, the first drive device 7 is used to control the flap 6 to rotate counterclockwise (with Figure 1 The orientation of the structure shown is taken as the basis) at a certain angle, at this time, the flap 6 is located in the first collecting hopper 301, and part of the first flakes 401 screened and dropped in the first area 201 of the roller screen 2 falls on the flap 6, and slides into the second collecting hopper 302 along the flap 6 to be mixed with the second flakes 402.
