[0002] A nut is a screw cap, a part used to fasten together with a bolt or a screw rod. It is an element that must be used in all manufacturing machinery. According to different materials, it is divided into several major types such as carbon steel, stainless steel, non-ferrous metals (such as copper), etc. It is a part that tightly connects mechanical equipment. Through the internal thread, nuts and bolts of the same specification can be connected together. The working principle of the nut is to use the friction between the nut and the bolt for self-locking.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. By setting the feeding table, conveyor belt, blanking plate and sorting component, the device uses the sorting component to sort nuts of different specifications. Utilizing the height difference between nuts of different specifications, the heights between multiple conveyor belts and the feeding table are decreasing.

[0016] 2. By setting the side support seat, side support, support rod, L-shaped bracket, first hydraulic rod, retaining seat, buffer block, auxiliary roller, buffer spring, first motor, driving wheel disc and driving wheel disc, adjusting the first hydraulic rod to expand and contract drives the sorting seat to move up and down, changing the heights of multiple conveyor belts and the feeding table, thereby adjusting the overall height of the sorting component to meet the sorting requirements of nuts of different specifications; the buffer block can buffer the nuts when they fall onto the conveyor belt, enabling them to quickly reach force balance with the conveyor belt and thus be conveyed along with the conveyor belt.

[0017] 3. By setting the blanking component, the nuts sliding down from the blanking cylinder will be sleeved on the outside of the aggregate rod. When a certain number is reached, the shaft drives the blanking shaft seat to rotate, pouring the collected nuts into the sliding chute in batches; the blanking component can temporarily store the sorted nuts and then pour them into the corresponding sliding chute in batches, facilitating the collection of the sorted nuts by personnel.

[0018] 4. By setting the lifting component, the lifting component can place the put-in nuts flat and then convey them upward, ensuring that the nuts are in a sequential conveying state, facilitating subsequent sorting operations; the upper outer wall of the material leveling table is arc-shaped, facilitating the sliding of nuts, and the rotating directions of the material leveling table and the spiral lifting blade are opposite, facilitating the falling of nuts and subsequent lifting and conveying; during the conveying process, the non-flat nuts will slide sideways due to uneven force and fall into the material leveling table from the spiral lifting blade, being conveyed twice, ensuring that the nuts conveyed by the spiral lifting blade can all be placed flat; the anti-slip grooves on the inner disc increase the friction between the nuts and the inner disc, facilitating the nuts to be conveyed along with the reverse feeding tray rotation, and the inclined inner disc facilitates the subsequent separation of nuts from the inner disc.

Detailed implementation manner

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0030] An intelligent sorting machine device for nuts of different sizes, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, includes three feeding tables 1. Inside each feeding table 1, a conveyor belt 2 is provided, and the shape of the conveyor belt 2 is an inclined upward slope. A plurality of equally spaced grooves are opened on the feeding table 1. The outer walls of the grooves are all connected to the blanking plate 3 by bolts. Above the feeding table 1, a sorting assembly is provided. The sorting assembly includes a sorting seat 4, a lower bracket 5 and a cross bracket 6. The lower bracket 5 and the cross bracket 6 are both located below the sorting seat 4. The sorting seat 4 is connected to the lower bracket 5 by bolts, and a plurality of fixing rods are connected between the lower bracket 5 and the cross bracket 6 by bolts. The feeding table 1 is located between the lower bracket 5 and the cross bracket 6. On the opposite outer walls of the lower bracket 5 and the cross bracket 6, a plurality of equally spaced rectangular grooves are opened. Between the upper and lower inner walls of the rectangular grooves, a rotating rod 7 is rotatably connected by bearings, and sleeve wheels 8 are connected to the outer walls of the rotating rods 7 by bolts. Between two opposite sleeve wheels 8, a feeding belt 9 is provided, and the heights between the plurality of feeding belts 9 are in a decreasing pattern.

[0031] Furthermore, as Figure 2 , Figure 3 and Figure 4As shown in the figure, side support seats 10 are provided below each of the three feeding platforms 1. On the other side of the side support seats 10, there are side support seats 11. On the upper outer walls of the side support seats 10 and the side support seats 11, support rods 12 are connected by bolts. Between the top end of the support rod 12 and the lower outer wall of the feeding platform 1, they are connected by bolts. On the upper outer wall of the side support seat 11, an L-shaped bracket 13 is connected by bolts. A first hydraulic rod 14 is provided on the L-shaped bracket 13. Between the bottom end of the first hydraulic rod 14 and the upper outer wall of the sorting seat 4, they are connected by bolts. And on the sorting seat 4, a round hole is opened. On the inner wall of the round hole, a first motor 19 is connected by bolts. The output end of the first motor 19 is connected by a coupling to a short shaft. On the outer wall of the short shaft, a driving pulley 20 is connected by bolts. The tops of multiple rotating rods 7 on the lower rack 5 all pass through the lower rack 5 and are connected by bolts to a driven pulley 21. Between the driving pulley 20 and the driven pulley 21, they are rotationally connected by a belt. Adjusting the first hydraulic rod 14 to expand and contract drives the sorting seat 4 to move up and down, so that the heights of the multiple conveying belts 9 and the feeding platform 1 are changed, thereby adjusting the overall height of the sorting component to adapt to the sorting requirements of nuts of different specifications; at one end of each of the three feeding platforms 1, a stop seat 15 is connected by bolts. Between the lower outer wall of the stop seat 15 and the upper outer wall of the side support seat 10, they are connected by bolts. On one side of the stop seat 15, a buffer block 16 is provided. And on the buffer block 16, a groove is opened. Between the inner walls on both sides of the groove, two symmetric auxiliary rollers 17 are rotatably connected by bearings. Between the buffer block 16 and the stop seat 15, a buffer spring 18 is connected by bolts. The buffer block 16 can buffer the nuts when they fall onto the conveyor belt 2, enabling them to quickly reach a force balance with the conveyor belt 2, and thus be conveyed along with the conveyor belt 2.

[0032] Furthermore, as Figure 3 and Figure 5 shown, below each of the multiple blanking plates 3, a blanking cylinder 22 is connected by bolts. Below the blanking cylinder 22, a blanking component is provided; the blanking component includes multiple blanking shaft seats 23 and a blanking table 24. The multiple blanking shaft seats 23 are evenly distributed at equal intervals. On the outer walls of the multiple blanking shaft seats 23, three equally spaced aggregate rods 27 are connected by bolts in a circumferential manner. The blanking table 24 is located below the blanking shaft seats 23. On the blanking table 24, multiple equally spaced sliding grooves 28 are opened. And on the side support seat 10, a second motor 25 is connected by bolts. The output end of the second motor 25 is connected by a coupling to a shaft rod 26. The other end of the shaft rod 26 passes through the multiple blanking shaft seats 23 and is rotatably connected to the outer wall of the side support seat 11 by bearings. Between the multiple blanking shaft seats 23 and the shaft rod 26, they are all connected by bolts. The blanking component can temporarily store the sorted nuts and then pour them into the corresponding sliding grooves 28 in batches, facilitating the collection of the sorted nuts by personnel.

[0033] Furthermore, as Figure 6 、 Figure 7 and Figure 8As shown in the figure, a base 29 is arranged between three side support seats 10. The three side support seats 10 are circumferentially and equidistantly distributed on the outer side of the base 29. A fixing cylinder 30 is bolted to the upper outer wall of the base 29, and a material lifting assembly is arranged inside the fixing cylinder 30. The material lifting assembly can place the nuts flat and then convey them upward, ensuring that the nuts are conveyed in sequence, which is convenient for subsequent sorting operations. The material lifting assembly includes a material leveling table 31 and a spiral material lifting blade 32. The upper surface wall of the material leveling table 31 is arc-shaped. A bottom column 33 is bolted to the lower outer wall of the material leveling table 31. The bottom column 33 is rotatably connected to the base 29 through a bearing. A sleeve gear 34 is bolted to the outer wall of the bottom column 33. A rotating cylinder 35 is bolted to the lower outer wall of the spiral material lifting blade 32. The rotating cylinder 35 is rotatably connected to the fixing cylinder 30 through a bearing. An annular groove is formed in the inner wall of the rotating cylinder 35, and an inner ring gear 36 is bolted to the inner wall of the annular groove. The upper outer wall of the material leveling table 31 is arc-shaped, which is convenient for the nuts to slide. The rotating directions of the material leveling table 31 and the spiral material lifting blade 32 are opposite, which is convenient for the nuts to fall and for subsequent upward material conveying. The inner ring gear 36 is located outside the sleeve gear 34. A third motor 37 is bolted to the bottom inner wall of the base 29. The output end of the third motor 37 is connected to a short shaft through a coupling. The other end of the short shaft is bolted to a first driving gear 38. The first driving gear 38 is located between the inner ring gear 36 and the sleeve gear 34, and the first driving gear 38 meshes with the inner ring gear 36 and the sleeve gear 34 respectively.

[0034] Furthermore, as Figure 6 , Figure 8 and Figure 9 shown, a reverse material conveying disk 39 is rotatably connected to the outer side of the upper end of the spiral material lifting blade 32 through a bearing. An inner disk 40 is bolted to the upper outer wall of the reverse material conveying disk 39. Anti-slip grooves are formed in the inner disk 40. The inner disk 40 is arranged as an inclined slope. An outer attached tooth disk 42 is arranged at the lower end of the reverse material conveying disk 39. A material conveying motor 43 is bolted to the base 29. The output end of the material conveying motor 43 is connected to a short shaft through a coupling. The other end of the short shaft is bolted to a second driving gear 44. The second driving gear 44 meshes with the outer attached tooth disk 42. The anti-slip grooves on the inner disk 40 increase the friction between the nuts and the inner disk 40, which is convenient for the nuts to be conveyed along with the rotation of the reverse material conveying disk 39. The inclined inner disk 40 is convenient for the subsequent separation of the nuts from the inner disk 40. An annular block 47 is rotatably connected to the outside of the reverse material conveying disk 39. Three circumferentially equidistant grooves are formed in the annular block 47. A blanking box 45 is bolted to the outer wall of each groove. A support column 46 is bolted to the lower outer wall of each blanking box 45. The three support columns 46 are bolted to the three side support seats 10 respectively. An auxiliary blanking convex block 41 is bolted to the upper outer wall of the spiral material lifting blade 32.

[0035] Working principle: Before sorting nuts, adjust the sorting component of the device according to the nut specifications to be sorted. Adjust the first hydraulic rod 14 to expand and contract to drive the sorting seat 4 to move up and down, so that the heights of multiple conveying belts 9 and the feeding table 1 change (the heights between multiple conveying belts 9 and the feeding table 1 are in a decreasing pattern, and subsequently, nuts at different heights can be separated in sequence. The preset height values between multiple conveying belts 9 are the height differences between different nuts), so that nuts of different specifications can be sorted according to their heights subsequently;

[0036] After the adjustment is completed, start the device. Put nuts of different specifications on the material leveling table 31. The third motor 37 drives the material leveling table 31 and the rotating cylinder 35 to rotate respectively through the sleeve teeth 34 and the inner ring teeth 36. The rotating directions of the material leveling table 31 and the rotating cylinder 35 are opposite. The rotation of the material leveling table 31 facilitates the nuts placed thereon to fall onto the spiral lifting blades 32 (the outer wall on the upper side of the material leveling table 31 is arc-shaped, which is convenient for the nuts to slide. The rotating directions of the material leveling table 31 and the spiral lifting blades 32 are opposite, which is convenient for the nuts to fall and subsequent lifting and conveying). The nuts falling onto the spiral lifting blades 32 are conveyed upward along with the rotation of the spiral lifting blades 32 (during the conveying process, the non-flat nuts will slide sideways due to uneven force and fall into the material leveling table 31, and are conveyed again, ensuring that the nuts conveyed by the spiral lifting blades 32 can all be flat). After being conveyed to the top of the spiral feeding blades, under the thrust of the auxiliary blanking convex block 41, the nuts will leave the spiral feeding blades and enter the reverse conveying tray 39. The reverse conveying tray 39 rotates at a constant speed under the drive of the conveying motor 43, and its rotating direction is opposite to that of the spiral lifting blades 32. After the nuts enter the reverse conveying tray 39, due to the inclination of the inner disk 40, the nuts will incline towards the annular block 47 (the anti-slip grooves on the inner disk 40 increase the friction between the nuts and the inner disk 40, facilitating the nuts to be conveyed along with the rotation of the reverse conveying tray 39, and the inclined inner disk 40 is convenient for the subsequent separation of the nuts from the inner disk 40). When the nuts are conveyed to the groove of the annular block 47, under the influence of their own gravity and centrifugal force, the nuts will separate from the inner disk 40 and enter the blanking box 45, and slide down from the blanking box 45 to the feeding table 1;

[0037] The nuts fall onto the feeding table 1 and are conveyed upward under the action of the conveyor belt 2. Multiple conveying belts 9 are always in a rotating state under the drive of the first motor 19. The nuts will successively reach the positions of multiple conveyor belts. When the nuts and the conveyor belt are at the same height, the upward conveyance of the nuts is blocked and they are forced by the conveyor belt to move outward. The nuts enter the blanking plate 3 and slide into the blanking cylinder 22. The nuts successively pass through conveyor belts at different heights to realize the sorting operation of nuts of different specifications; The nuts sliding down from the blanking cylinder 22 will be sleeved outside the aggregate rod 27. When a certain number is reached, the shaft rod 26 drives the blanking shaft seat 23 to rotate, and the collected nuts are poured into the sliding chute 28 in batches.

[0038] As described above, it is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
