[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1 to 3 The present invention provides the following technical solution: A resin particle size control device includes a base, a rotary vibration module, and a particle screening module. The rotary vibration module is installed on the base and can move within a certain range of the base. The particle screening module is installed on the rotary vibration module and can drive the particle screening module to vibrate along a circumferential rotation trend. The rotary vibration module includes a connecting ring plate 5, a connecting sleeve 6, and a rotary vibration mechanism. The connecting ring plate 5 is fixedly installed at the top of the connecting sleeve 6, and the rotary vibration mechanism is fixedly installed inside the connecting sleeve 6. The connecting sleeve 6 is located inside the base and is separated from the base. Several springs 4 are evenly arranged between the connecting ring plate 5 and the top of the base. One end of the spring 4 is fixedly connected to the connecting ring plate 5, and the other end of the spring 4 is fixedly connected to the base, so that the connecting ring plate 5 and the connecting sleeve 6 can move within a certain range inside the base. The rotary vibration mechanism includes a drive motor 7 and an eccentric block 8. The drive motor 7 is fixedly installed inside the connecting sleeve 6. The output shaft of the drive motor 7 is connected to the eccentric block 8. When the drive motor 7 rotates and drives the eccentric block 8 to rotate together, the drive motor 7 can vibrate along the circumference. The drive motor 7 can drive the connecting sleeve 6 and the particle screening module to rotate and vibrate together in a circular motion. The particle screening module includes several receiving trays 9 and several sorting screens 13. The receiving trays 9 are fixedly installed on the connecting ring plate 5. Each sorting screen 13 is installed on the receiving tray 9 in sequence. The mesh size of each sorting screen 13 decreases from top to bottom, so that each sorting screen 13 can screen the resin particles in sequence. The remaining resin particles after screening enter the receiving tray 9.

[0018] The drive motor 7 is a dual-output shaft motor. Eccentric blocks 8 are installed on both output shafts of the drive motor 7. The two eccentric blocks 8 are symmetrically arranged at the drive motor 7. The two output shafts of the drive motor 7 drive the two symmetrically arranged eccentric blocks 8. The two eccentric blocks 8 are located on the two output shafts at both ends of the drive motor 7. The two eccentric blocks 8 can provide forces in opposite directions and in a staggered manner, which can effectively improve the amplitude of the drive motor 7, and thus effectively improve the vibration efficiency and strength of the drive motor 7 driving the connecting sleeve 6.

[0019] The receiving tray 9 and each sorting screen 13 are equipped with a discharge mechanism on their side. The discharge mechanism is a connecting pipe 11, which is fixedly installed on the side wall of the receiving tray 9 or the sorting screen 13. The receiving tray 9 and the rotary vibrator are driven by the rotary vibrator module to rotate in a circular direction, so that the sorting screen 13 and the receiving tray 9 can generate a certain centrifugal force, which can throw the screened resin particles along the side wall of the sorting screen 13 and the receiving tray 9 into the connecting pipe 11 on their side. The connecting pipe 11 can then discharge the screened resin particles.

[0020] A discharge pipe 12 is provided at the end of the connecting pipe 11 away from the sorting screen 13 and the receiving tray 9. The discharge pipe 12 is installed vertically at the connecting pipe 11. The discharge pipe 12 can change the discharge direction of the resin particles, so that the sorting screen 13 and the receiving tray 9 can discharge the resin particles in a specific direction, thus preventing the resin particles from being thrown to the outside.

[0021] The bottom of the receiving tray 9 is a conical guide cone 10, which can guide the resin particles in the middle of the receiving tray 9 to the edge of the receiving tray 9, thereby improving the discharge efficiency of the receiving tray 9.

[0022] A cover 14 is installed at the bottom of the topmost sorting screen 13. The cover 14 can prevent resin particles from being thrown out randomly when the topmost sorting screen 13 vibrates. The cover 14 has an inverted bucket-shaped structure. A feed inlet 15 is opened in the middle of the cover 14. The feed inlet 15 is used to input resin particles into the sorting screen 13 located at the top of the device.

[0023] The base includes a base plate 1, a support sleeve 2, and a support ring plate 3. The base plate 1 and the support ring plate 3 are respectively located at the two ends of the support sleeve 2. The connecting sleeve 6 is located inside the support sleeve 2 and the two are separated. The support ring plate 3 and the connecting ring plate 5 are connected by several springs 4, which facilitates the vibration module to drive the particle sorting module to vibrate.

[0024] The specific implementation process is as follows: When using this resin particle size control device to screen resin particles, to control the particle size, first select the plastic and aperture of the sorting screen 13 as needed. Then, install the receiving tray 9 and each sorting screen 13 sequentially on the connecting ring plate 5. Next, start the drive motor 7. The drive motor 7 drives the two eccentric blocks 8 to rotate. Under the action of the two eccentric blocks 8, the drive motor 7 continuously swings along a circumferential rotation. The drive motor 7, through the connecting sleeve 6 and the connecting ring plate 5, drives the receiving tray 9 and each sorting screen 13 to vibrate along a circumferential rotation. Then, the material is fed through the top of the cover 14. Resin particles are fed into the sorting screen 13 at the top of the device through port 15. The resin particles are sequentially vibrated and screened by the sorting screens 13 to control the particle size. The resin particles remaining in each sorting screen 13 are thrown into the connecting pipe 11 by centrifugal force, and then discharged through the discharge pipe 12. The resin particles that have passed through the multiple sorting screens 13 fall into the guide cone 10 of the receiving tray 9, and are guided by the guide cone 10 to the edge of the receiving tray 9, and finally discharged from the device. This completes the screening of resin particles and controls the particle size of the resin particles for packaging.

[0025] This resin particle size control device allows for the sequential installation of multiple sorting screens 13 with different apertures on a rotary vibration mechanism, facilitating user adjustment and control of the resin particle screening size. The rotary vibration module drives each sorting screen 13 to vibrate circumferentially, effectively improving the screening efficiency of the sorting screen 13. Furthermore, the rotational vibration causes the screened resin particles to be discharged through the connecting pipe 11 and the discharge pipe 12 under centrifugal force. This device has a simple structure, facilitates the replacement of each sorting screen 13 to control the screening particle size of the resin particles, and the rotary vibration effectively improves the screening efficiency of the device.
