[0041] like Figures 1 to 7 As shown, the present invention provides an automatic sorting and circulation device, comprising:

[0042] The outer frame 1 includes four vertically arranged support rods 101 , and the upper ends of two adjacent support rods 101 are connected by a horizontally arranged first connecting rod 102 .

[0043] The circulation mechanism 2 includes a circulation tube 201 , an upper partition plate 202 , a lower partition plate 203 , a circulation motor 204 , a circulation shaft 205 and a circulation gear 206 .

[0044] The circulation tube 201 is a vertical hollow tube with openings at both ends, and the lower end of the circulation tube 201 is a circulation port. The outer frame 1 also includes two first fixing rods 103 arranged horizontally, and the two ends of the first fixing rods 103 are respectively fixedly connected to the first connecting rods 102. The two first fixing rods 103 are respectively arranged on both sides of the circulation tube 201, and the circulation tube 201 is fixedly connected to the first fixing rods 103. An isolation hole 2011 is horizontally opened on the circulation tube 201, and the isolation hole 2011 is located above the circulation port. The isolation hole 2011 horizontally penetrates the internal space of the circulation tube 201, and the part of the circulation tube 201 located between the isolation hole 2011 and the circulation port is suitable for placing a product.

[0045] The upper partition 202 and the lower partition 203 are both arranged horizontally, the upper partition 202 is located above the lower partition 203, the upper partition 202 can be horizontally inserted into the isolation hole 2011, and the lower partition 203 can be horizontally moved to a position blocking the flow port. The lower surface of the upper partition 202 is convexly provided with a first convex tooth group 2021, and the upper surface of the lower partition 203 is convexly provided with a second convex tooth group 2031. The first convex tooth group 2021 and the second convex tooth group 2031 are both multiple rows of convex teeth arranged side by side. The flow shaft 205 is horizontally arranged between the upper partition 202 and the lower partition 203, and two flow gears 206 are coaxially fixedly arranged on the flow shaft 205, and the first convex tooth group 2021 and the second convex tooth group 2031 are both meshed with the flow gear 206.

[0046] The outer frame 1 also includes two limiting walls 104 arranged opposite to each other. The two limiting walls 104 are respectively arranged vertically on both sides of the flow tube 201. The two ends of the two limiting walls 104 are respectively fixed with second connecting rods 105, and the ends of the second connecting rods 105 are fixedly connected to the support rod 101. The flow motor 204 is fixedly arranged on the limiting wall 104, and the rotating shaft of the flow motor 204 is arranged horizontally. The rotating shaft of the flow motor 204 passes through the limiting wall 104 and is coaxially fixedly connected with the flow shaft 205. The limiting wall 104 is provided with a first guide groove 1041 and a second guide groove 1042 both arranged horizontally. The first guide groove 1041 is located above the second guide groove 1042. The upper partition 202 is horizontally protruded with a third connecting rod on both sides. The end of the third connecting rod is coaxially provided with a rollable roller 207, and the roller 207 on the third connecting rod is rollingly arranged in the first guide groove 1041. The lower partition 203 has a fourth connecting rod protruding horizontally on both sides, and a rollable roller 207 is coaxially arranged on the fourth connecting rod, and the roller 207 on the fourth connecting rod is rollably arranged in the second guide groove 1042. The first roller 207 and the second roller 207 can make the horizontal movement of the upper partition 202 and the lower partition 203 more stable.

[0047] After the circulation motor 204 is started, the circulation shaft 205 is driven to rotate, and the circulation shaft 205 drives the circulation gear 206 to rotate, and the upper partition 202 and the lower partition 203 can move horizontally under the drive of the circulation gear 206. In this embodiment, only one of the upper partition 202 and the lower partition 203 can prevent the circulation of the product in the circulation tube 201 at the same time.

[0048] In the initial state, the upper partition 202 is inserted into the isolation hole 2011 to prevent the flow of the product located above the isolation hole 2011. At this time, the lower partition 203 does not block the flow port.

[0049] When the circulation motor 204 rotates forward, the lower partition 203 moves horizontally to the bottom of the circulation port, and the upper partition 202 moves horizontally away from the isolation hole 2011 until the lower partition 203 completely blocks the circulation port. At this time, the product above the isolation hole 2011 is no longer blocked by the upper partition 202, and falls between the isolation hole 2011 and the circulation port. The lower partition 203 can prevent the product between the isolation hole 2011 and the circulation port from flowing.

[0050] When the circulation motor 204 reverses, the upper partition 202 is horizontally inserted into the isolation hole 2011 and separates the product falling between the isolation hole 2011 and the circulation port from the product above it, and the lower partition 203 is horizontally moved away from the circulation tube 201 under the drive of the circulation gear 206 until the upper partition 202 is completely inserted into the isolation hole 2011. At this time, the upper partition 202 horizontally cuts off the internal space of the circulation tube 201, and the upper partition 202 can prevent the circulation of the product located above the isolation hole 2011, and at the same time, the lower partition 203 no longer prevents the circulation of the product located between the isolation hole 2011 and the circulation port, and the product flows out of the circulation port.

[0051] The scanning mechanism 3 includes a scanner 301 . The scanning port of the scanner 301 is vertically arranged upwards. The scanner 301 is fixedly connected to the lower surface of the lower partition 203 via a fixing frame 302 .

[0052] In this embodiment, the product information is set at the bottom of the product. The lower partition 203 is made of a transparent material, such as transparent plastic or transparent glass. When the lower partition 203 blocks the circulation port, the bottom of the product is tightly set against the upper surface of the lower partition 203. The scanner 301 can scan the information of the product located between the isolation hole 2011 and the circulation port through the lower partition 203.

[0053] The sorting mechanism 4 is arranged in the outer frame 1 and is located below the circulation mechanism 2. The sorting mechanism 4 includes a base frame 401, a flap 402, a lifting cylinder 403 and a limiting cylinder 404.

[0054] The flap 402 is arranged below the flow port, and includes a plate surface 4021 and a turning column 4022. In this embodiment, the plate surface 4021 is a square plate with a certain thickness, and the four turning columns 4022 are respectively arranged on the periphery of the four sides of the plate surface 4021, and the turning columns 4022 are fixedly connected to the plate surface 4021 through a fifth connecting rod extending outward from the lower surface of the plate surface 4021. When the plate surface 4021 is arranged horizontally, the four turning columns 4022 are also arranged horizontally, and the axis of the turning column 4022 is recorded as the turning axis.

[0055] The bottom frame 401 includes a bottom plate 4011 and a bottom frame 4012. The bottom frame 4012 is a square frame that is horizontally arranged and has a hole in the middle. The bottom plate 4011 is located below the middle of the bottom frame 4012. The bottom plate 4011 is connected to the bottom frame 4012 through four sixth connecting rods 4013. Four arc-shaped first limiting grooves 4014 are evenly arranged on the upper surface of the bottom frame 4012. The flap 402 is arranged on the bottom frame 4012. When the flap 402 is arranged horizontally, each flip column 4022 can be coaxially arranged in one of the first limiting grooves 4014. When there is only one flip column 4022 that is restricted in the first limiting groove 4014, the flap 402 can rotate around the restricted flip column 4022.

[0056] The end of the cylinder body of the lifting cylinder 403 is connected to the base plate 4011 through a universal joint 405, and the end of the telescopic rod of the lifting cylinder 403 is connected to the middle of the lower surface of the plate 4021 through a universal joint 405.

[0057] A fixing plate 4015 extends horizontally inward from the bottom frame 4012, and a limiting cylinder 404 is fixedly arranged below the fixing plate 4015. A limiting cylinder 404 is arranged below each first limiting groove 4014, and a telescopic rod of the limiting cylinder 404 is arranged horizontally outward. A first limiting block 4041 is fixed at the end of the telescopic rod of the limiting cylinder 404, and a circular arc-shaped second limiting groove 4042 is formed on the first limiting block 4041.

[0058] When the telescopic rod of the limiting cylinder 404 is retracted, the first limiting groove 4014 can cooperate with the second limiting groove 4042 to form a limiting portion suitable for limiting the flip column 4022, and the flip column 4022 can be rotatably arranged in the limiting portion. Different limiting cylinders 404 can limit different flip columns 4022, and the extension of the telescopic rod of the lifting cylinder 403 can make the flap 402 rotate around the flip column 4022 limited by the limiting portion and flip in different directions.

[0059] The circulation mechanism 2 first limits the product between the circulation port and the isolation hole 2011 through the lower partition 203, and the scanner 301 set on the lower partition 203 obtains product information. The circulation mechanism 2 then blocks the product above the isolation hole 2011 through the upper partition 202, and the product below the isolation hole 2011 flows out from the circulation port to the plate surface 4021. The limit cylinder 404 limits the corresponding turning column 4022 according to the specific type of the product, and the telescopic rod of the lifting cylinder 403 extends, and the flap 402 rotates around the restricted turning column 4022. After the flap 402 tilts to a certain angle, the product rolls off the plate surface 4021 to the corresponding direction for subsequent circulation or other operations.

[0060] According to another embodiment, a circle of third limiting grooves 4023 is formed on the flip column 4022 .

[0061] In this embodiment, the first limiting groove 4014 has a protrusion with a second limiting block 4016 suitable for being clamped in the third limiting groove 4023, and the second limiting groove 4042 has a protrusion with a third limiting block 4043 suitable for being clamped in the third limiting groove 4023. When the first limiting groove 4014 and the second limiting groove 4042 form a limiting portion in a coordinated manner, the second limiting block 4016 and the third limiting block 4043 can be clamped in the third limiting groove 4023, preventing the flip plate 402 from axially moving in the limiting portion when the flip plate 402 rotates around the flip post 4022, thereby improving the stability of the flip plate 402 when rotating.

[0062] According to another embodiment, a plurality of guide slopes 4024 are provided on the flap 402 , and the guide slopes 4024 extend outward from the edge of the flap 402 to the oblique upper part of the flap 402 , and a corresponding guide slope 4024 is provided above each flip column 4022 .

[0063] The guide slope 4024 can prevent the product from falling outside the plate surface 4021 when the product falls from the transfer port. The guide slope 4024 blocks the flip column 4022 and the first stop block when the flap 402 rotates around the flip column 4022, which can prevent the product from contacting the flip column 4022 and the first stop block 4041 when leaving the plate surface 4021, thereby affecting the quality of the product and the normal operation of the flap 402. In this embodiment, the angle between the guide slope 4024 and the flap 402 is in the range of 130° to 150°.
