Abstract
Description
Technical Field
[0001] This utility model relates to the field of granulator technology, specifically to a granulator screen structure. Background Technology
[0002] A granulator is a molding machine that can shape materials into specific shapes. In practical use, it employs a special screw design and various configurations to produce recycled and mixed granules of various plastics such as PP, PE, PS, ABS, PA, PVC, PC, POM, EVA, LCP, PET, and PMMA. The granulator's internal gearbox features a high-torque design, enabling smooth and noiseless operation. The screw and barrel undergo special hardening treatment, resulting in wear resistance, good mixing performance, and high output. Furthermore, the granulator's design includes vacuum or regular exhaust ports to remove moisture and waste gas during production, leading to more stable output, stronger granules, and guaranteed excellent product quality.
[0003] However, in actual processing, due to the objective influence of the easy connection between particles, some modified particles may stick together during production. If these stuck particles are not dealt with in time during the receiving stage, they will increase the probability of blockage of the internal channels of the corresponding equipment during subsequent use, affecting the overall production efficiency of the process.

Detailed Implementation
[0025] 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.
[0026] Please see Figures 1-5 A granulator screen structure includes a cylindrical collection box 1 and a filter frame plate 2. The filter frame plate 2 is fitted inside the top of the cylindrical collection box 1. A first filter screen 3 is nested inside the filter frame plate 2. A motor component 5 is provided at the bottom of the filter frame plate 2. The output end of the motor component 5 is driven to a scraper 6 that is movably connected to the top surface of the filter frame plate 2. The scraper 6 can reciprocate to clean and prevent clogging of the first filter screen 3 inside the filter frame plate 2 under the drive of the motor component 5.
[0027] The motor component 5 includes an outer protective shell 51, a motor 52, and a battery module 53. A support frame is installed between the surface of the outer protective shell 51 and the bottom surface of the middle part of the filter frame plate 2. The motor 52 and the battery module 53 are both installed inside the outer protective shell 51 and are electrically connected. The battery module 53 is electrically connected to a switch installed on the surface of the support frame. The output end of the motor 52 is installed in the middle structure of the filter frame plate 2 through a bearing and extends to the top outer side of the filter frame plate 2. One end of the scraper 6 is connected to the end of the output end of the motor 52. The motor component 5 is used as a power source to make the scraper 6 filter and collect the granulated raw materials on the filter frame plate 2 and the first filter screen 3, while scraping and collecting the large particles of raw materials formed by adhesion on the top surface of the first filter screen 3, so as to avoid the first filter screen 3 from clogging and maintain the continuous filtering effect of the first filter screen 3.
[0028] The inner wall of the top of the cylindrical collection box 1 is provided with an internal thread, and the surface of the filter frame plate 2 is provided with a first external thread that can be helically engaged with the internal thread, so that it can be threadedly connected to the inner side of the top of the cylindrical collection box 1, thereby providing convenient disassembly and replacement conditions for the filter frame plate 2 and the components set on the filter frame plate 2 in subsequent turnover and use.
[0029] In use, the shaped granulated raw materials output from the granulator are collected using a cylindrical collection box 1 and a filter frame plate 2. The specific operation is as follows:
[0030] Before assembling the filter frame plate 2 and the cylindrical collection box 1 by threaded connection, turn on the motor 52 inside the motor component 5 by switching on the switch. Then, the output end of the motor 52 drives the scraper 6 to rotate at a low speed. After the cylindrical collection box 1 and the filter frame plate 2 are assembled, place the whole device below the discharge port of the existing granulator. Then, make the granulator to feed the material. The output granular raw material will be filtered and screened by the first filter screen 3 inside the filter frame plate 2, and then enter the cylindrical collection box 1 for centralized collection.
[0031] For large particles of raw material that are filtered out by the top surface of the first filter screen 3 due to adhesion, the output end of the motor 52 drives the scraper 6 to scrape the top surface of the first filter screen 3 back and forth. This scrapes and concentrates the large particles of raw material that are filtered out by the top surface of the first filter screen 3 due to adhesion, so as to avoid the first filter screen 3 from becoming clogged and to maintain the continuous filtering effect of the first filter screen 3.
[0032] Please see Figures 1-5 A shielding cylinder 11 is installed on the top of the second ring plate 8. The top diameter of the shielding cylinder 11 is smaller than the bottom diameter. A first ring plate 7, a second ring plate 8, and a filter ring assembly 9 are arranged on the outside of the top of the filter frame plate 2. The filter ring assembly 9 is fitted between the bottom of the outer ring of the first ring plate 7 and the bottom of the inner ring of the second ring plate 8. The inner wall of the top of the inner ring of the first ring plate 7 is fixedly connected to the surface of the top of the filter frame plate 2.
[0033] In use, the combination of the first ring plate 7, the second ring plate 8, and the filter ring assembly 9 forms a defect collection space on the outside of the filter frame plate 2. Subsequently, after the large particles of raw material scraped and cleaned by the scraper 6 exceed the length range of the scraper 6, some of the large particles of raw material will enter the annular space formed by the first ring plate 7, the second ring plate 8, and the filter ring assembly 9 under the action of centrifugation for secondary screening and collection.
[0034] Please see Figures 1-5 The other end of the scraper 6 is fixedly connected to a stirring plate 4 located between the first ring plate 7 and the second ring plate 8. A buffer groove is provided inside the stirring plate 4. The filter ring assembly 9 includes an annular frame plate 91. The outer ring surface and the inner ring inner wall of the annular frame plate 91 are respectively fixed to the inner wall of the bottom of the second ring plate 8 and the surface of the bottom of the first ring plate 7. Several second filter screens 92 are nested inside the annular frame plate 91 along its own circumference. The bottom surface of the second ring plate 8 is provided with a second external thread and is threaded to an annular collection box 10 that covers the bottom of the filter ring assembly 9. The annular collection box 10 is made of transparent material.
[0035] During use, considering that some large particles are formed by the simple adhesion of adjacent particles, the large particles collected in the annular space are stirred and beaten by the synchronous rotation of the stirring plate 4 and the scraper 6. This disperses the large particles formed by the simple adhesion of adjacent particles and filters them through the second filter screen 92 inside the filter ring assembly 9 into the annular collection box 10 for collection. This achieves three screenings and optimizes the overall operation of the device.
