[0020] A method for using a device for timely and quantitatively distributing small particles, comprising:

[0021] S1. First, when using the small particle timing and quantitative distribution device to pack the particles, the particles to be packed are poured into the interior of the funnel, and the funnel makes the particles slide into the top of the screening net, thereby making the output end of the first motor rotate to drive the turntable to rotate. When the turntable rotates, the cooperation between the driving rod and the connecting frame can make the driving plate do reciprocating motion inside the first limiting ring. When the driving plate does reciprocating motion, the position of the connecting plate is driven to move. When the position of the connecting plate moves, the position of the frame is driven to slide by the sliding rod, thereby driving the position of the screening net to shake. When the screening net is shaking, the particles that fall on the top of the screening net can be screened, so as to achieve the purpose of screening the particles to be packed, and large objects carried in the particles to be packed can be screened out, thereby preventing the large particles from entering the interior of the packaging container when the subsequent small particle timing and quantitative distribution device is used to pack the particles.

[0022] S2. The particles screened by the screening net will enter the inside of the discharge trough. When the small particles are distributed and packaged in a timed and quantitative manner, the output end of the servo motor is rotated to drive the rotating shaft to rotate inside the support ring. When the support ring rotates, the position of the concave groove is moved. After the concave groove moves to the bottom of the discharge trough, the screened particles will pass through the discharge trough and enter the inside of the concave groove. The position of the concave groove moves, so that the small particles stored inside enter the inside of the square groove. The square groove allows the small particles to enter the inside of the packaging container through the discharge pipe for storage. The control module can control the rotation speed of the rotating shaft, and then the particles can be discharged in a timed manner. Small particles can be quantitatively discharged through the space inside the concave groove. When the capacity inside the concave groove is adjusted, the power supply module provides energy for the motor, and the output end of the motor rotates to drive the rotating rod to rotate. When the rotating rod rotates, it drives the threaded rod to rotate. When the threaded rod rotates, the position of the threaded ring moves. When the position of the threaded ring moves, it drives the position of the plate to move. After the plate moves into the concave groove, the capacity inside the concave groove can be adjusted, so as to achieve the purpose of quickly adjusting the capacity inside the concave groove, and then the amount of material delivered by the small particle timing and quantitative distribution device can be quickly adjusted;

[0023] S3. When the small particle timing and quantitative distribution device is dispensing objects, the dispensing container is placed on the top of the support table for support. When the position of the support table is adjusted according to different dispensing containers, the output end device of the second motor drives the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, the two sets of slip rings move in opposite directions. When the slip ring moves, the position of the support table is pushed to move by the long plate. After the position of the support table moves, the dispensing container supported on the top can be driven to move, and then the position of the dispensing container can be adjusted according to the dispensing containers of different sizes, and then the discharge pipe makes it easy for the dispensing small particles to enter the interior of the dispensing container, effectively avoiding the dispensing container from being far away from the discharge pipe outlet and causing scattering;

[0024] S4. When clearing small particles scattered on the top of the support platform, the electric push rod is operated to push the sliding frame out of the square box. When the position of the sliding frame moves, it drives the position of the suction trough to move. After the suction trough and the support platform are in a horizontal state, the exhaust fan works through the pipeline to make the air inside the suction trough flow, so that the suction trough generates suction. The suction force sucks the scattered small particles into the interior of the suction trough, and the filter screen blocks the small particles. After the blocked small particles fall into the interior of the trough body, the trough body allows the small particles to slide into the interior of the receiving trough for collection, thereby achieving the purpose of collecting the small particles scattered during the operation of the small particle timing and quantitative distribution device, and reducing labor intensity.

[0025] Preferably, in step S1, the following steps are also included:

[0026] S11, the slide groove guides the moving sliding rod so that the sliding rod can slide horizontally;

[0027] In the step S2, the following steps are also included:

[0028] S21, when the plate moves, the guide rod is driven to slide horizontally inside the limit frame to locate the position, and then the guide rod can guide the plate;

[0029] In step S3, the following steps are also included:

[0030] S31, when the position of the support platform is moved, the guide shaft can guide the position of the support platform through the cylinder, so that the support platform can slide vertically;

[0031] In step S4, the following steps are also included:

[0032] S41. A slide rail is provided at the bottom of the storage slot, so that the interior of the square box can be pulled out.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. The present invention can screen the particles to be packaged in the small particle timing and quantitative distribution device by installing a screening net and a driver. The funnel makes the particles slide into the top of the screening net, and then the output end of the first motor rotates to drive the turntable to rotate. When the turntable rotates, the cooperation between the driving rod and the connecting frame can make the driving plate do a reciprocating motion inside the first limiting ring. When the driving plate does a reciprocating motion, the position of the connecting plate is driven to move. When the position of the connecting plate moves, the position of the frame is driven to slide by the sliding rod, thereby driving the position of the screening net to shake. When the screening net is shaking, the particles falling on the top of the screening net can be screened, so as to achieve the purpose of screening the particles to be packaged, and large objects carried in the particles to be packaged can be screened out, thereby preventing the large particles from entering the interior of the packaging container when the subsequent small particle timing and quantitative distribution device is packaging the particles.

[0035] 2. The present invention can quickly adjust the output amount of the small particle timing and quantitative distribution device by installing a box and a plate. The small particle can be quantitatively discharged through the space inside the concave groove. When the capacity inside the concave groove is adjusted, the power supply module provides energy for the motor. The output end of the motor rotates to drive the rotating rod to rotate. When the rotating rod rotates, it drives the threaded rod to rotate. When the threaded rod rotates, the position of the threaded ring moves. When the position of the threaded ring moves, it drives the position of the plate to move. After the plate moves into the concave groove, the capacity inside the concave groove can be adjusted, so as to achieve the purpose of quickly adjusting the capacity inside the concave groove, and then the amount of material delivered by the small particle timing and quantitative distribution device can be quickly adjusted.

[0036] 3. The present invention can quickly adjust the position of the table surface supporting the packaging container inside the small particle timed and quantitative distribution device by installing a regulator and a support table. When the small particle timed and quantitative distribution device is dispensing objects, the dispensing container is placed above the support table for support. When the position of the support table is adjusted according to different dispensing containers, the output end device of the second motor drives the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, the two sets of slip rings move in opposite directions. When the slip ring moves, the position of the support table is pushed to move by the long plate. After the position of the support table moves, the dispensing container supported on the top can be driven to move, and then the position of the dispensing container can be adjusted according to the dispensing containers of different sizes, and then the discharge pipe makes it easy for the dispensing small particles to enter the interior of the dispensing container, effectively avoiding the scattering phenomenon caused by the dispensing container being far away from the discharge pipe outlet;

[0037] 4. The present invention can remove the particles generated during the dispensing of the small particle timing and quantitative distribution device by installing a square box and a sliding frame. When the small particles scattered on the top of the support platform are removed, the electric push rod is operated to push the sliding frame to move out of the square box. The movement of the sliding frame drives the position of the suction trough to move, so that the suction trough and the support platform are in a horizontal state. The exhaust fan works through the pipeline to make the air inside the suction trough flow, thereby causing the suction trough to generate suction. The suction force sucks the scattered small particles to move into the interior of the suction trough, and the filter screen blocks the small particles. After the blocked small particles fall into the interior of the trough body, the trough body causes the small particles to slide into the interior of the receiving trough for collection, thereby achieving the purpose of collecting the small particles scattered during the operation of the small particle timing and quantitative distribution device and reducing labor intensity.

[0058] S1. First, when using the small particle timing and quantitative distribution device to pack the particles, the particles to be packed are poured into the interior of the funnel 5. The funnel 5 allows the particles to slide into the top of the screening net 24, and then the output end of the first motor 18 rotates to drive the turntable 19 to rotate. When the turntable 19 rotates, the driving plate 15 can make a reciprocating motion inside the first limiting ring 14 through the cooperation between the driving rod 17 and the connecting frame 16. When the driving plate 15 makes a reciprocating motion, the position of the connecting plate 20 is driven to move.

[0059] S2. The particles screened by the screening net 24 will enter the inside of the discharge trough 6. When the small particles are distributed and packaged in a timed and quantitative manner, the output end of the servo motor 10 is rotated to drive the rotating shaft 8 to rotate inside the support ring 7. When the support ring 7 rotates, the position of the concave groove 9 is moved. After the concave groove 9 moves to the bottom of the discharge trough 6, the screened particles will pass through the discharge trough 6 and enter the inside of the concave groove 9. The position of the concave groove 9 moves, so that the small particles stored inside enter the inside of the square groove 11.

Small particles can be quantitatively discharged through the space inside the concave groove 9. When the capacity inside the concave groove 9 is adjusted, the power supply module 31 provides energy for the motor 32. The output end of the motor 32 rotates to drive the rotating rod 33 to rotate. When the rotating rod 33 rotates, it drives the threaded rod 34 to rotate. When the threaded rod 34 rotates, the position of the threaded ring 28 moves. When the position of the threaded ring 28 moves, it drives the position of the plate 26 to move. After the plate 26 moves into the concave groove 9, the capacity inside the concave groove 9 can be adjusted, so as to achieve the purpose of quickly adjusting the capacity inside the concave groove 9, and then the amount of material delivered by the small particle timing and quantitative distribution device can be quickly adjusted.

[0060] S3. When the small particle timing and quantitative distribution device is dispensing objects, the dispensing container is placed on the top of the support platform 36 for support. When the position of the support platform 36 is adjusted according to different dispensing containers, the output end device of the second motor 41 drives the bidirectional lead screw 40 to rotate. When the bidirectional lead screw 40 rotates, the two sets of slip rings 42 move in opposite directions. When the slip ring 42 moves, the position of the support platform 36 is pushed to move by the long plate 43. After the position of the support platform 36 moves, the dispensing container supported on the top can be driven to move, and then the position of the dispensing container can be adjusted according to the dispensing containers of different sizes, and then the discharge pipe 12 facilitates the dispensing of small particles into the interior of the dispensing container, effectively avoiding the dispensing container from being far away from the outlet of the discharge pipe 12 and causing scattering.

[0061] S4. When the small particles scattered on the top of the support platform 36 are cleared, the electric push rod 53 is operated to push the sliding frame 45 out of the square box 44. When the position of the sliding frame 45 moves, the position of the suction trough 48 is driven to move. After the suction trough 48 and the support platform 36 are in a horizontal state, the exhaust fan 46 works to make the air inside the suction trough 48 flow through the pipe 47, so that the suction trough 48 generates suction, and the suction sucks the scattered small particles to move into the suction trough 48. The filter screen 49 blocks the small particles. After the blocked small particles fall into the interior of the trough body 50, the trough body 50 allows the small particles to slide into the interior of the receiving trough 51 for collection, thereby achieving the purpose of collecting the small particles scattered during the operation of the small particle timing and quantitative distribution device, reducing labor intensity.

[0063] S11, the slide groove 21 guides the moving sliding rod 22 so that the sliding rod 22 can slide horizontally;

[0064] In step S2, the following steps are also included:

[0065] S21, when the plate 26 moves, the guide rod 30 is driven to slide horizontally inside the limit frame 29 to position the plate 26, so that the guide rod 30 can guide the plate 26;

[0066] In step S3, the following steps are also included:

[0067] S31, when the position of the support platform 36 is moved, the guide shaft 38 can guide the position of the support platform 36 through the cylinder 37, so that the support platform 36 can slide vertically;

[0069] S41, a slide rail is provided at the bottom of the storage groove 51, which can be pulled out of the interior of the square box 44.

[0070] Working principle: first, when using the small particle timing and quantitative distribution device to pack the particles, pour the particles to be packed into the funnel 5, and the funnel 5 makes the particles slide into the top of the screening net 24, so that the output end of the first motor 18 rotates to drive the turntable 19 to rotate. When the turntable 19 rotates, the cooperation between the driving rod 17 and the connecting frame 16 can make the driving plate 15 reciprocate inside the first limit ring 14. When the driving plate 15 reciprocates, the position of the connecting plate 20 is driven to move. When the position of the connecting plate 20 moves, the sliding rod 22 drives the frame 23 to slide, thereby driving the position of the screening net 24 to shake. When the screening net 24 shakes, the particles that fall on the top of the screening net 24 can be The particles are screened to achieve the purpose of screening the particles to be packaged. Large objects carried in the particles to be packaged can be screened out, avoiding the subsequent small particles. When the timing and quantitative distribution device is packaging the particles, large particles enter the interior of the packaging container, and the particles screened by the screening net 24 will enter the interior of the discharge trough 6. When the small particles are distributed and packaged in a timely and quantitative manner, the output end of the servo motor 10 is rotated to drive the rotating shaft 8 to rotate inside the support ring 7. When the support ring 7 rotates, it drives the position of the concave groove 9 to move. After the concave groove 9 moves to the bottom of the discharge trough 6, the screened particles will pass through the discharge trough 6 and enter the interior of the concave groove 9. The position of the concave groove 9 moves, allowing the small particles stored inside to enter the concave groove 9. The square groove 11 allows small particles to enter the interior of the subpackaging container through the discharge pipe 12 for storage. The control module 54 can control the rotation speed of the rotating shaft 8, so that the particles can be discharged at a fixed time. The small particles can be quantitatively discharged through the space inside the concave groove 9. When the capacity inside the concave groove 9 is adjusted, the power supply module 31 provides energy for the motor 32. The output end of the motor 32 rotates to drive the rotating rod 33 to rotate. When the rotating rod 33 rotates, it drives the threaded rod 34 to rotate. When the threaded rod 34 rotates, the position of the threaded ring 28 moves. When the position of the threaded ring 28 moves, it drives the position of the plate 26 to move. After the plate 26 moves into the interior of the concave groove 9, it can The capacity inside the concave groove 9 is adjusted to achieve the purpose of quickly adjusting the capacity inside the concave groove 9, and then the amount of material delivered by the small particle timing and quantitative distribution device can be quickly adjusted. When the small particle timing and quantitative distribution device is distributing objects, the distributing container is placed on the top of the support platform 36 for support. When the position of the support platform 36 is adjusted according to different distributing containers, the output end device of the second motor 41 drives the bidirectional lead screw 40 to rotate. When the bidirectional lead screw 40 rotates, the two sets of slip rings 42 move in opposite directions. When the slip ring 42 moves, the position of the support platform 36 is pushed to move by the long plate 43. After the position of the support platform 36 moves, the distributing container supported on the top can be driven to move.Then, the position of the sub-packaging container can be adjusted according to the sub-packaging containers of different sizes, so that the discharge pipe 12 facilitates the sub-packaging of small particles into the interior of the sub-packaging container, effectively avoiding the sub-packaging container from being scattered due to being far away from the outlet of the discharge pipe 12. When the small particles scattered on the top of the support platform 36 are removed, the electric push rod 53 is operated to push the sliding frame 45 out of the interior of the square box 44. When the position of the sliding frame 45 moves, the position of the suction trough 48 is driven to move, so that the suction trough 48 and the support platform 36 are in the water. After reaching the flat state, the exhaust fan 46 works to make the air inside the suction trough 48 flow through the pipe 47, thereby generating suction in the suction trough 48, which sucks the scattered small particles into the suction trough 48, and the filter 49 blocks the small particles. After the blocked small particles fall into the trough body 50, the trough body 50 allows the small particles to slide into the storage trough 51 for collection, thereby achieving the purpose of collecting the small particles scattered during the operation of the small particle timing and quantitative distribution device, and reducing the labor intensity.
