The plastic particles in the material guiding assembly 2 fall into the material falling assembly 7. The material falling assembly 7 is in close connection with the bottom end of the material guiding assembly 2. The material falling assembly 7 is fixedly connected to the driving device 6.

[0020] Furthermore, two first convex sliding grooves 13 and a guiding groove 14 are formed on the upper surface of the mounting plate 12. The driving device 6 is slidably connected in the first convex sliding grooves 13 and the guiding groove 14, so that the driving device 6 is fixedly installed.

[0021] Furthermore, the driving device 6 includes a motor 61. The motor 61 is fixedly connected to a mounting seat 62. The bottom end of the mounting seat 62 is fixedly arranged on the upper surface of the bottom plate 1. The output end of the motor 61 is fixedly connected to a driving gear 63. The driving gear 63 is meshed with a driven gear 64. The motor 61 drives the driving gear 63 and the driven gear 64 to rotate. The driven gear 64 is rotatably connected to a rectangular frame 65. The bottom end of the rectangular frame 65 is fixedly arranged on the upper surface of the bottom plate 1. A rectangular sliding groove 651 is formed on the upper surface of the rectangular frame 65. A rotating column 66 is arranged in the rectangular frame 65. One end of the rotating column 66 is fixedly connected to the driven gear 64. The driven gear 64 drives the rotating column 66 to rotate. A swirling groove 661 is formed on the outer surface of the rotating column 66. An L-shaped push rod 67 is slidably arranged in the swirling groove 661 and the rectangular sliding groove 651. The L-shaped push rod 67 is slidably arranged in the guiding groove 14. One end of the L-shaped push rod 67 is fixedly connected to a sliding rod 68.

Two convex sliding blocks 69 are fixedly arranged on the bottom surface of the sliding rod 68. The convex sliding blocks 69 are slidably arranged in the first convex sliding grooves 13. Thus, when the rotating column 66 rotates, it can drive the L-shaped push rod 67 to move back and forth along the rectangular sliding groove 651.

[0022] Further, the material guiding assembly 2 includes a supporting platform 21. The upper surface of the supporting platform 21 is fixedly connected to a storage hopper 3. The bottom end of the supporting platform 21 is fixedly arranged on the upper surface of the bottom plate 1. A plurality of first rectangular grooves 22 are formed on the upper surface of the supporting platform 21. A receiving hopper 23 is fixedly arranged on the bottom surface of the supporting platform 21. The receiving hopper 23 is in through connection with the first rectangular grooves 22, so that the plastic particles in the first rectangular grooves 22 can fall into the receiving hopper 23. The bottom end of the receiving hopper 23 is fixedly connected to a conical hopper 24. The bottom surface of the conical hopper 24 is in fitting connection with a blanking assembly 7.

[0023] Further, the storage hopper 3 is conical. A plurality of second rectangular grooves 31 are formed on the inner bottom surface of the storage hopper 3. A feeding assembly 5 is connected in the second rectangular grooves 31. The second rectangular grooves 31 are in overlapping connection with the first rectangular grooves 22. A cover 32 is fixedly arranged at the upper end of the storage hopper 3. The cover 32 is rotationally connected to a stirring assembly 4, so that the plastic particles in the storage hopper 3 can fall from the second rectangular grooves 31 and the first rectangular grooves 22.

[0024] Further, the stirring assembly 4 includes a first guide plate 46. A second convex chute 461 is formed on the upper surface of the first guide plate 46. A convex rack 47 is slidably connected in the second convex chute 461. The convex rack 47 is meshed with a first gear 48. The first gear 48 is rotatably arranged at the bottom end of a connecting seat 15. The first gear 48 is fixedly connected to a first bevel gear set 41. The first bevel gear set 41 drives a second bevel gear set 42 and a third bevel gear set 43. The third bevel gear set 43 is fixedly connected to a vertical shaft 44. The vertical shaft 44 is rotationally connected to the cover 32. A plurality of stirring rods 45 are fixedly arranged outside the bottom end of the vertical shaft 44. Thus, when the convex rack 47 reciprocally slides, it can drive a plurality of stirring rods 45 to rotate through the first gear 48 and stir the plastic particles in the storage hopper 3.

[0025] Further, the feeding assembly 5 includes a fourth bevel gear set 51. The fourth bevel gear set 51 is fixedly connected to a linkage assembly 8. The linkage assembly 8 can drive the fourth bevel gear set 51 to rotate. The fourth bevel gear set 51 drives a fifth bevel gear set 52. The fifth bevel gear set 52 is fixedly connected to a transmission shaft 54. A support plate 53 is fixedly arranged outside the transmission shaft 54. The bottom end of the support plate 53 is fixedly arranged on the upper surface of the supporting platform 21. The transmission shaft 54 movably penetrates through the storage hopper 3 and is fixedly connected to a plurality of batching plates 55. The plurality of batching plates 55 are respectively rotatably arranged in a plurality of second rectangular grooves 31. A plurality of arc grooves 551 are formed on the batching plates 55. The outer surface of the batching plate 55 is rotationally in fit with the inner wall of the second rectangular groove 31. Thus, when the batching plate 55 rotates, the plastic particles can be conveyed through the plurality of arc grooves 551.

[0026] Further, the linkage component 8 includes a second guide plate 81. A third convex chute 82 is formed in the second guide plate 81. A convex slide bar 83 is slidably arranged in the third convex chute 82. The convex slide bar 83 slides along the second guide plate 81. An installation groove 831 is formed in the upper surface of the convex slide bar 83. Two cross plates 84 are fixedly arranged on the upper surface of the convex slide bar 83. A plurality of active ratchet teeth 86 are installed in the installation groove 831. The active ratchet teeth 86 are rotatably connected to the inner wall of the cross plate 84. The active ratchet teeth 86 are meshed with a ratchet wheel 87. The ratchet wheel 87 is fixedly connected to the fourth bevel gear set 51. The upper end of the ratchet wheel 87 is meshed with a passive ratchet tooth 89. The upper end of the passive ratchet tooth 89 is rotatably connected to a base 88. The upper end of the base 88 is fixedly arranged on the bottom surface of the connecting seat 15. Thus, when the plurality of active ratchet teeth 86 move away from the motor 61, the ratchet wheel 87 can be driven to rotate, so that the batching disc 55 rotates. When the plurality of active ratchet teeth 86 move towards the motor 61, due to the limiting effect of the passive ratchet tooth 89 on the ratchet wheel 87, the active ratchet teeth 86 are not sufficient to drive the ratchet wheel 87 to rotate, so that the batching disc 55 stops rotating, realizing the quantitative conveying of plastic particles.

[0027] Further, the blanking component 7 includes a feeding plate 71. The upper surface of the feeding plate 71 is in fit connection with the bottom end of the conical hopper 24. When the feeding plate 71 moves towards the motor 61, the upper surface of the feeding plate 71 is in fit connection with the bottom end of the conical hopper 24, preventing the plastic particles in the conical hopper 24 from leaking out. When the first material groove 711 is in fit with the bottom end of the conical hopper 24, the feeding of the plastic particles in the conical hopper 24 is completed. A first material groove 711 is formed in the upper surface of the feeding plate 71. Connecting blocks 72 are fixedly connected to both sides of the feeding plate 71. The bottom ends of the connecting blocks 72 are fixedly connected to slide rods 68. The bottom surface of the feeding plate 71 is in fit connection with an L-shaped discharging plate 73. A second material groove 731 is formed in the upper surface of the L-shaped discharging plate 73. The bottom end of the L-shaped discharging plate 73 is fixedly arranged on the upper surface of the mounting plate 12. When the feeding plate 71 moves away from the motor 61, the bottom surface of the feeding plate 71 is in fit connection with the upper surface of the L-shaped discharging plate 73 until the first material groove 711 finally overlaps with the second material groove 731, completing the final discharging.

[0028] A method for feeding plastic particles with a quantitative function includes the following steps: Step 1: Plastic particles are stored in the storage hopper 3. The motor 61 drives the driving gear 63 and the driven gear 64 to rotate, causing the rotating column 66 to rotate within the rectangular frame 65. The L-shaped push rod 67 is driven to reciprocate along the rectangular chute 651 through the spiral groove 661. When the sliding rod 68 is driven to move away from the motor 61 along the first convex chute 13, multiple driving pawls 86 drive the ratchet wheel 87 to rotate, and the transmission shaft 54 is driven to rotate through the fourth bevel gear set 51 and the fifth bevel gear set 52, causing multiple dosing plates 55 to rotate within the second rectangular groove 31 in the storage hopper 3, and the plastic particles in the storage hopper 3 are conveyed into the receiving hopper 23 and the conical hopper 24, and thus are conveyed into the first material groove 711 of the feeding plate 71 through the conical hopper 24; Step 2: When the sliding rod 68 is driven to move towards the motor 61, due to the ratchet wheel 87 being blocked by the passive pawl 89, the multiple driving pawls 86 are not sufficient to drive the ratchet wheel 87 to rotate, and the ratchet wheel 87 remains stationary, the dosing plate 55 stops rotating, and the feeding terminates. The bottom surface of the first material groove 711 of the feeding plate 71 loaded with plastic particles is in contact with the upper surface of the L-shaped discharge plate 73. As the sliding rod 68 displaces, the first material groove 711 finally overlaps with the second material groove 731, so that a fixed amount of plastic particles are discharged. The reciprocating displacement of the sliding rod 68 can drive the convex rack 47 to slide back and forth along the first guide plate 46, causing the first gear 48 to drive the first bevel gear set 41 to rotate forward and backward, and the vertical shaft 44 drives multiple stirring rods 45 to stir the plastic particles in the storage hopper 3.

[0029] Working principle: Plastic particles are stored in the storage hopper 3, and the motor 61 drives the driving gear 63 and the driven gear 64 to rotate, so that the rotating column 66 rotates in the rectangular frame 65, and drives the L-shaped push rod 67 to move back and forth along the rectangular slide 651 through the swing groove 661. When the slide bar 68 is driven to move along the first convex slide 13 away from the motor 61, multiple active ratchets 86 drive the ratchet 87 to rotate, and drive the transmission shaft 54 ​​to rotate through the fourth bevel gear set 51 and the fifth bevel gear set 52, so that multiple ingredient plates 55 rotate in the second rectangular groove 31 in the storage hopper 3, so that the plastic particles in the storage hopper 3 are transported to the receiving hopper 23 and the conical bucket 24, and then transported to the first material groove 711 of the feeding plate 71 through the conical bucket 24. When the slide bar 68 is driven to move along the first convex slide 13 away from the motor 61, multiple active ratchets 86 drive the ratchet 87 to rotate, and drive the transmission shaft 54 ​​to rotate through the fourth bevel gear set 51 and the fifth bevel gear set 52, so that multiple ingredient plates 55 rotate in the second rectangular groove 31 in the storage hopper 3, and deliver the plastic particles in the storage hopper 3 to the receiving hopper 23 and the conical bucket 24, and then deliver them to the first material groove 711 of the feeding plate 71 through the conical bucket 24. When the rod 68 moves toward the direction approaching the motor 61, the ratchet 87 is hindered by the passive ratchet 89, and the multiple active ratchets 86 are not sufficient to drive the ratchet 87 to rotate. The ratchet 87 is in a stationary state, the batching plate 55 stops rotating, and the feeding is terminated. The bottom surface of the first trough 711 of the feeding plate 71 loaded with plastic particles is in contact with the upper surface of the L-shaped discharge plate 73. With the displacement of the slide bar 68, the first trough 711 is finally overlapped with the second trough 731, so that a certain amount of plastic particles are discharged. The reciprocating displacement of the slide bar 68 can drive the convex rack 47 to slide back and forth along the first guide plate 46, so that the first gear 48 drives the first bevel gear set 41 to rotate forward and reverse, and the vertical shaft 44 drives the multiple stirring rods 45 to stir the plastic particles in the storage hopper 3.
