Technical Field

[0001] This utility model relates to the field of vibrating screening technology for plastic granules, specifically a vibrating screening device for PPO plastic granules. Background Technology

[0002] Polyphenylene oxide (PPO), also known as polyphenylene ether b, is one of the world's five major general-purpose engineering plastics. It has advantages such as high rigidity, high heat resistance, flame retardancy, high strength and excellent electrical properties. In addition, PPO also has the advantages of wear resistance, non-toxicity and pollution resistance. PPO has one of the lowest dielectric constants and dielectric losses among engineering plastics, and is almost unaffected by temperature and humidity.

The top of the guide rods extends into the interior of the vibrating plate and is movably connected to the vibrating plate. A screening frame is fixedly connected to the top of the vibrating plate.

[0004] Although the device is equipped with a screening device, most existing plastic particle screening devices only perform screening once, which cannot classify the particles according to their size, thus reducing work efficiency. Furthermore, it is inconvenient to collect the screened plastic particles after screening.

[0005] Therefore, there is a need to provide a vibrating screening device for PPO plastic granules. Utility Model Content

[0006] The purpose of this utility model is to provide a PPO plastic pellet vibrating screening device to solve the problems mentioned in the background art, which are mostly limited to one screening, unable to classify the particles according to particle size, thus reducing work efficiency, and making it inconvenient to collect the screened plastic particles after screening.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PPO plastic granule vibrating screening device, comprising a mounting plate, a vibrating screening mechanism fixedly mounted on the top surface of the mounting plate, and a grading screening and collection mechanism fixedly mounted on the top surface of the vibrating screening mechanism; the vibrating screening mechanism includes a mounting platform, a fixing plate fixedly mounted on the top surface of the mounting platform, a servo motor fixedly mounted on the side of the fixing plate, a turntable fixedly mounted on the end face of the transmission rod of the servo motor, a fixing pin fixedly mounted on the side of the turntable, a mounting sleeve sleeved on the side of the fixing pin, a limit rod fixedly mounted on the side of the mounting sleeve, a connecting sleeve slidably mounted on the side of the limit rod, a housing fastened to the side of the connecting sleeve by fixing bolts, a first limiting block fixedly mounted on the side of the housing, a first guide rail slidably mounted inside the first limiting block by a sliding sleeve, a mounting frame fixedly mounted on the end face of the first guide rail, and the bottom end face of the mounting frame fixedly connected to the top surface of the mounting plate.

[0009] Preferably, the grading and screening collection mechanism includes a feeding port, the bottom surface of which is fixedly connected to the top surface of the box.

[0010] Preferably, a first screen plate is fixedly installed on the inner wall of the box, a second screen plate is fixedly installed on the inner wall of the box, the first screen plate is installed below the second screen plate, a sliding groove is fixedly opened on the side of the feeding port, a horizontal plate is snapped into the inner wall of the sliding groove, and a handle is fixedly installed on the side of the horizontal plate.

[0011] Preferably, a through hole is fixedly opened on the side of the box body, and a second discharge plate is fixedly installed on the inner wall of the through hole. A first discharge plate is fixedly installed on the inner wall of the through hole.

[0012] Preferably, a first collection box is slidably mounted on the top surface of the mounting plate, a second collection box is slidably mounted on the top surface of the mounting plate, and a third collection box is slidably mounted on the top surface of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) In this PPO plastic granule vibrating screening equipment, during screening, gripping and pulling the handle causes the horizontal plate to be pulled out of the feeding port, further adding PPO plastic granules into the box. Then, the servo motor is activated, causing the turntable to rotate, which in turn causes the fixing pin to deflect, moving the mounting sleeve and the limit rod in the connecting sleeve. This, in turn, causes the box to reciprocate, moving the first and second screen plates to perform a three-stage screening of the PPO plastic granules. During the reciprocating motion of the box, the first and second limit blocks assist in the movement along the first and second guide rails, enabling the screening of PPO plastic granules and improving screening quality and efficiency.

[0016] 2) This PPO plastic granule vibrating screening equipment, during screening, drives the box body to move through the vibrating screening mechanism, further screening the PPO plastic granules. The granules are further screened through a second screen plate. Larger granules pass through the through holes on the side of the box and the second discharge plate, exiting the box. Smaller granules fall onto the surface of the first screen plate for secondary screening, and are then discharged through the second discharge plate and collected in the second and third collection boxes respectively. Even smaller granules fall directly into the first collection box for collection. This completes the three-stage screening and collection of PPO plastic granules. This three-stage screening solves the problem that most existing plastic particle screening devices only perform one screening, failing to classify particles according to size, reducing work efficiency, and making it inconvenient to collect the screened plastic particles after screening.

A housing 312 is fastened to the side of the connecting sleeve 308 by fixing bolts. A first limiting block 311 is fixedly installed on the side of the housing 312. A first guide rail 310 is slidably installed inside the first limiting block 311 by a sliding sleeve. An installation frame 309 is fixedly installed on the end face of the first guide rail 310.

[0028] Specifically, during screening, gripping and pulling the handle 405 causes the horizontal plate 404 to be pulled out of the feeding port 403, further adding PPO plastic granules into the housing 312. This further activates the servo motor 303, causing the turntable 304 to rotate, which in turn causes the fixing pin 305 to deflect, moving the mounting sleeve 306 and the limit rod 307 in the connecting sleeve 308. This, in turn, causes the housing 312 to reciprocate, thereby moving the first screen plate 401 and the second screen plate 402 to perform a three-stage screening of the PPO plastic granules. During the reciprocating motion of the housing 312, the first limit block 311 and the second limit block 314 assist in the movement along the first guide rail 310 and the second guide rail 313.

Larger granules pass through the through holes on the side of the housing 312 and the first discharge plate 406 to exit the housing 312.
