[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0033] like Figure 1-10 As shown, an antibacterial plastic particle screening system includes a base plate 1, a screening frame 3 is provided on the base plate 1 through a vibration unit 2, a grading screening unit 4 for screening plastic particles is provided in the screening frame 3, and a driving control unit 5 for controlling the operation of the grading screening unit 4 is provided in the screening frame 3;

[0034] By adopting the above technical solution, during the specific operation process, the plastic particles to be screened are placed into the screening frame 3, and then the grading screening unit 4 is controlled by the driving control unit 5 to screen the plastic particles, so that plastic particles within the same specification range can be distinguished and collected. The efficiency of plastic particle screening is improved by automatically screening and collecting plastic particles, and the grading screening unit can accurately screen and distinguish plastic particles, thereby improving the effect of plastic particle screening.

[0035] The vibration unit 2 includes a vibrating telescopic rod 21 installed on the base plate 1 for buffering and guiding the screening frame 3, the screening frame 3 is installed on the vibrating telescopic rod 21, and the screening frame 3 is provided with a feed hopper 23 with a trumpet-shaped structure, a rotating motor 24 is installed on the base plate 1, and an elliptical roller 25 is installed on the output shaft of the rotating motor 24, and a limiting groove is provided on the elliptical roller 25, and the lower end of the screening frame 3 is provided with an abutment rod 26, and the abutment rod 26 is slidably connected to the limiting groove.

[0036] After the plastic particles are put into the screening frame 3 through the feed hopper 23, the rotating motor 24 is started to drive the elliptical roller 26 to rotate and adjust. The elliptical roller 26 drives the vibrating screening frame 3 to vibrate up and down under the action of the mutual cooperation of the vibrating telescopic rod 21 and the abutting rod 26, thereby increasing the speed of plastic particle screening, so that the plastic particles smaller than the corresponding grading screening unit 4 can fall down quickly, while the plastic particles that meet the specifications remain on the corresponding grading screening unit 4.

[0037] The drive control unit 5 includes a drive motor 51 installed on the inner wall of the lower end of the screening frame 3, a drive plate 52 is installed on the output shaft of the drive motor 51, a drive cylinder 53 is installed on the drive plate 52, a centrifugal plate 54 is installed on the drive cylinder 53, and the diameter of the centrifugal plate 54 decreases from top to bottom. A drive component 55 that cooperates with the screening mechanism 41 is installed on the drive cylinder 53.

[0038] When the screening frame 3 vibrates as a whole, the driving motor 51 drives the driving plate 52 to rotate. The driving plate 52 synchronously drives the driving assembly 55 to rotate during the rotation. The driving assembly 55 drives the grading screening unit 4 to rotate and adjust synchronously during the movement. The grading screening unit 4 moves up and down relative to the screening frame 3, thereby accelerating the screening speed of plastic particles.

[0039] The grading and screening unit 4 includes an execution screening mechanism 41 evenly arranged from top to bottom inside the screening frame 3. The screening frame 3 is provided with a discharge mechanism 42 that cooperates with the execution screening mechanism 41. The execution screening mechanism 41 is used to filter and screen the plastic particles. The plastic particles after screening and filtering are discharged from the discharge mechanism 42.

[0040] The diameter of the leakage holes on the screening mechanism 41 in the screening frame 3 decreases step by step from top to bottom, thereby completing the screening of different plastic particles and ensuring that the screened plastic particles meet the corresponding specifications.

[0041] The execution screening mechanism 41 includes an annular inner groove opened in the screening frame 3, and a lower slider 411 is evenly arranged on the inner wall of the lower end of the annular inner groove along its circumference, and a lower spring rod 412 is installed on the lower slider 411, and an annular support frame 413 is installed on the lower spring rod 412. An upper slider 414 is evenly arranged on the inner wall of the upper end of the annular inner groove along its circumference, and an upper spring rod 417 is arranged between the upper slider 414 and the annular support frame 413. A rubber cover is connected between the upper slider 414, the annular support frame 413 and the lower slider 411, and a screening branch chain 43 is provided on the annular support frame 413.

[0042] A control ring 415 is provided on the annular inner groove, and a fitting rod 416 is provided at the lower end of the annular support frame 413. The fitting rod 416 is abutted against the upper end surface of the control ring 415, and the end surface of the control ring 415 in contact with the fitting rod 416 is an uneven structure.

[0043] The screening branch chain 43 includes a circular frame 431 arranged on the upper end face of the annular support frame 413, and a No. 1 screening plate 432 is provided on the upper end face of the circular frame 431. A guide groove is evenly provided on the inner wall of the circular frame 431 along its circumference, and a guide rod 433 is slidably provided in the guide groove. The guide rod 433 is mounted on the No. 2 screening plate 434, and leakage holes are evenly provided on the No. 1 screening plate 432 and the No. 2 screening plate 434. The No. 2 screening plate 434 is evenly provided with circular rubber blocks 435. A blocking rubber block 436 is provided on the No. 2 screening plate 434 located between the two leakage holes. The circular rubber block 435 and the blocking rubber block 436 are both elastic rubbers, and in the initial state, the blocking rubber block 436 and the circular rubber block 435 both rest on the No. 1 screening plate 432.

[0044] The guide groove is in a Z-shaped structure.

[0045] The first screening plate 432 and the second screening plate 434 are both provided with through holes.

[0046] The driving assembly 55 includes a driving rod 551 installed on the centrifugal plate 54, and the driving rod 551 extends upward through the through hole. A clamping block 552 is provided on the driving rod 551, and the clamping block 552 is slidingly connected to the through hole. The driving rod 551 is located on the outer wall of the lower side of the No. 2 screening plate 434 and is provided with a lifting block 553. The lifting block 553 abuts against the lower side of the No. 2 screening plate 434. Lifting rods 554 are evenly arranged along the circumference of the driving rod 551 located on the upper side of the No. 1 screening plate 432, and the outer side of the lifting rod 554 is connected to the lifting ring 555.

[0047] The discharging mechanism 42 includes a discharging trough opened in the screening frame 3, and the discharging trough is located on the upper side of the annular inner groove. A lifting spring rod 421 is installed on the inner wall of the upper end of the discharging trough, and a blocking block 422 is installed at the lower end of the lifting spring rod 421. The cross-section of the inner lower end of the blocking block 422 is a triangular structure, and a discharging trough is also opened at the lower end of the screening frame.

[0048] When the driving rod 551 starts to rotate, the mutual cooperation between the block 552 and the through hole drives the circular frame 431 and the annular support frame 413 to rotate synchronously. During the rotation, the annular support frame 413 drives the fitting rod 416 to rotate along the upper end surface of the control ring 415. Since the upper end surface of the control ring 415 has an uneven structure, the annular support frame 413 vibrates up and down during this process, causing the plastic particles to shake on the No. 1 screening plate 432, thereby causing the plastic particles smaller than the leakage hole to fall down quickly.

[0049] After the plastic particles have completed the screening operation, the driving cylinder 53 drives the driving rod 551 to move upward from the bottom. During the movement, the driving rod 551 drives the second screening plate 434 to move upward through the lifting block 553. In this process, the second screening plate 434 is driven to rotate upward by the cooperation between the guide rod 433 and the guide groove. In this process, the annular rubber block 435 is squeezed and contracted, and the blocking rubber block 436 moves to the leakage hole on the first screening plate 432, and the leakage hole is blocked by the blocking rubber block 436, so that the upper end surface of the first screening plate 432 The driving rod 551 tends to be flat, and the lifting ring 555 on the lifting rod 554 is synchronously driven to squeeze the blocking block 422 during the upward movement. During this process, the blocking block 422 is synchronously moved upward, and the No. 1 screening plate 432 is driven to adjust upward by the driving cylinder 53, so that the No. 1 screening plate 432 moves to a position where it can cooperate with the discharge chute, and then the driving motor 51 is restarted to drive the driving rod 551 to rotate rapidly, so that the plastic particles after screening are ejected to the surroundings by the action of centrifugal force, and the ejected plastic particles are discharged from the discharge chute and fall into the drainage frame 31.

[0050] A drainage frame 31 cooperating with the discharge trough is provided on the outer wall of the screening frame 3, and the lower end surface of the inner wall of the drainage frame 31 is an upward inclined structure from front to back. A discharge port is provided at the front end of the drainage frame 31, and a drainage pipe 32 is provided at the discharge port. A positioning frame for fixing the drainage pipe 32 is provided on the bottom plate 1, and the drainage pipe 32 is connected to the positioning frame by a sliding fit. A storage frame 33 is provided on the bottom plate 1, and a partition plate is provided in the storage frame 33, which divides the storage frame 33 into several storage cavities.

[0051] The screening frame 3 in the vibrating state synchronously drives the drainage frame 31 to vibrate up and down, so that the plastic particles collected in the drainage frame 31 flow quickly toward the discharge port, and then the plastic particles are transported to the corresponding storage cavity through the drainage pipe 32.
