It includes a sorting cylinder and a sorting mechanism for sorting the diamond raw materials. The sorting mechanism is located inside the sorting cylinder. A rotating disk is fixed to the lower end of a rotating shaft, and a baffle is provided on the outer side of the rotating disk. Multiple sorting holes are opened on the rotating disk, and a pushing structure is provided between the rotating disk and the baffle to spread the raw materials on the surface of the rotating disk. Beneficial effects: The centrifugal force generated when the rotating disk rotates throws the raw materials on the surface outwards. During this throwing, small particles fall through the sorting holes and are screened below.

Description

Technical Field

[0001] This utility model relates to the field of sorting machine technology, and in particular to a raw material sorting machine for synthetic diamond. Background Technology

[0002] Diamond is a mineral composed of carbon and is an allotrope of carbon. With the diverse applications of diamond, companies use diamond raw material sorting machines to classify diamond raw materials by size to meet different product requirements during production.

[0003] By comparing a diamond raw material sorting machine with patent publication number CN219765984U, this solution uses a housing, fixed base, limiting rod, limiting plate, lower screen plate, spring, connecting column, upper screen plate, first motor, eccentric block and push seat to sort diamond raw materials into three particle sizes. However, because the upper and lower screen plates are inclined during sorting, small particles may be mixed between multiple large particles when the upper screen plate is screening large particles. After the large particles are screened out, the small particles mixed in will also be screened out, which may result in missed screening. This means that the small particles cannot be fully screened, requiring multiple sorting processes, increasing the sorting time and reducing the sorting efficiency. Utility Model Content

[0026] like Figures 1-5 As shown, a raw material sorting machine for synthetic diamonds includes a sorting cylinder 100 and a sorting mechanism for sorting diamond raw materials, the sorting mechanism being located inside the sorting cylinder 100.

[0027] In this embodiment: the sorting mechanism includes a rotating shaft 201 rotatably disposed inside the sorting cylinder 100. A main motor 202 is mounted on the rotating end of the rotating shaft 201. The output end of the main motor 202 is fixed to the rotating end of the rotating shaft 201 via a coupling. A rotating disk 203 is fixed to the lower end of the rotating shaft 201. The rotating disk 203 is a cone with its smaller end facing upwards. A baffle 207 is provided on the outer side of the rotating disk 203. An upper baffle 205 is provided on the upper end of the baffle 207. The baffle 207 and the upper baffle 205 are made of rubber. The rotating shaft 201... A lower baffle 204 is provided between the baffle 207 and the baffle barrel 207. The lower baffle 204 is made of silicone. The bottom end of the lower baffle 204 is in contact with the side wall of the rotating disk 203 and they slide together. A discharge frame 215 is provided on the side wall of the sorting cylinder 100 near the rear side of the lower baffle 204. A feed pipe is provided on the upper end of the sorting cylinder 100 near the front side of the lower baffle 204. Multiple sorting holes are provided on the rotating disk 203. A spreading structure is provided between the rotating disk 203 and the baffle barrel 207 to spread the raw materials on the surface of the rotating disk 203.

[0028] The pushing structure includes a connecting frame 206 fixedly mounted on the side wall of the sorting cylinder 100. A push rod 209 is slidably installed between the connecting frame 206 and the baffle 207. A pusher brush 208 is fixed to one end of the push rod 209 near the rotating shaft 201. The pusher brush 208 is arc-shaped at one end near the rotating shaft 201 and is a soft brush. A compression spring is connected between the push rod 209 and the baffle 207. A driving structure for driving multiple pusher brushes 208 to move is provided between the connecting frame 206 and the push rod 209. A vibration structure for driving the rotating disk 203 to vibrate is provided below the rotating disk 203.

[0029] The drive structure includes a small cone block 210 fixedly mounted on the end of the push rod 209 away from the rotating shaft 201. A gear ring 211 is provided on the side of the small cone block 210 away from the rotating shaft 201. The gear ring 211 is rotatably connected to the connecting frame 206. A connecting plate is fixedly mounted on the end of the connecting frame 206 away from the rotating shaft 201. A gear 213 is rotatably mounted on the lower end of the connecting plate. The gear 213 meshes with the gear ring 211. An auxiliary motor 214 is mounted on the rotating end of the gear 213. The output end of the auxiliary motor 214 is fixed to the rotating end of the gear 213 through a coupling. Multiple large cone blocks 212 are fixedly mounted around the end of the gear ring 211 near the small cone block 210. The large cone blocks 212 slide with the small cone block 210.

[0030] The vibration structure includes a fixed ring 216 located below the rotating disk 203. The fixed ring 216 is fixed to the inner wall of the sorting cylinder 100. Multiple fixed frames 217 are fixed around one end of the fixed ring 216 near the rotating shaft 201. Protrusions 218 are slidably installed inside the fixed frames 217. A pre-tightening spring is connected between the protrusions 218 and the fixed frames 217. Multiple fixed blocks 219 are fixed around the lower end of the rotating disk 203. The fixed blocks 219 and the protrusions 218 are arc-shaped at their closest points and slide together. The centrifugal force generated when the rotating disk 203 rotates will throw the raw material on the surface outward. During the throwing, small particles of raw material fall through the sorting holes and are screened below. Large particles of raw material accumulate at the bottom of the baffle 207. Then, the pushing structure pushes the accumulated raw material towards the center of the rotating disk 203, pushing away and flattening the small particles of raw material mixed in with the large particles, increasing the screening path of the small particles of raw material, and making the small particles of raw material fully sorted, thus improving the sorting efficiency.

[0031] Working principle: First, the diamond raw material is poured into the surface of the rotating disk 203 through the feed pipe. Then, the main motor 202 drives the rotating shaft 201 to rotate, which in turn drives the rotating disk 203 to rotate. The centrifugal force generated when the rotating disk 203 rotates will throw the raw material on the surface of the rotating disk 203 outward. During the throwing, small particles of raw material fall through the sorting holes and are screened below, while large particles of raw material accumulate at the bottom of the baffle 207.

[0032] Then, the auxiliary motor 214 drives the gear 213 to rotate in both directions. The gear 213 meshes with the gear ring 211, thereby driving the gear ring 211 to rotate in both directions. This, in turn, drives the multiple large cone blocks 212 on the inner wall of the gear ring 211 to rotate in both directions. When the multiple large cone blocks 212 rotate, they squeeze against the multiple small cone blocks 210, causing the small cone blocks 210 to drive the push rod 209 to move back and forth near the end of the rotating shaft 201. This, in turn, drives the pusher brush plate 208 to move back and forth, pushing the raw material accumulated at the bottom of the baffle 207 towards the center of the rotating disk 203. This pushes and flattens the small particles mixed in with the large particles, increases the screening path of the small particles, and ensures that the small particles are fully sorted, thus improving the sorting efficiency.

[0033] While sorting the raw materials, the rotation of the rotating disk 203 will cause multiple fixed blocks 219 at the bottom of the rotating disk 203 to rotate. As a result, the multiple fixed blocks 219 will squeeze and collide with the protrusions 218 in the fixed frame 217, which will cause the protrusions 218 to continuously strike the bottom of the rotating disk 203, causing the rotating disk 203 to vibrate slightly. This is more conducive to the screening of raw materials on the surface of the rotating disk 203 and reduces the blockage of the sorting holes by the raw materials. Under the action of pushing the pusher brush 208 and rotating the rotating disk 203, the large particles of raw materials will eventually move to the discharge frame 215 and be discharged outward through the discharge frame 215. The sorted small particles of raw materials will be discharged outward through the lower end of the sorting cylinder 100, thereby completing the sorting operation of diamond raw materials.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
