[0002] Plastic granules refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics, special plastics, general-purpose plastics, polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. The granulator is mainly composed of feeding, stirring, granulating, transmission and lubrication systems, etc. It is widely used in the pharmaceutical, chemical and food industries, and plastic granules need to be prepared by a granulator.

[0003] When existing granulation devices produce plastic particles, since there are certain differences in the produced particles, usually after production is completed, the produced particles need to be put into screening equipment for screening, and then the screened unqualified particles are recycled. The production efficiency of plastic particles is affected by both the transportation speed and the screening speed, which is time-consuming and labor-intensive. Therefore, it is necessary to design corresponding technical solutions to solve the existing technical problems. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0018] See also Figure 1-3A recyclable GPO bead extrusion granulation device comprises a casing 1, a granulator 2 is arranged on the top of the casing 1, and a discharge port 3 is arranged on the side of the casing 1, and an inclined discharge tray 4 is fixedly arranged on the side of the casing 1 corresponding to the position of the discharge port 3, and an inclined first screen 5, a second screen 6 and a guide plate 7 are arranged in sequence from top to bottom in the casing 1, wherein the inclination directions of the first screen 5, the second screen 6 and the guide plate 7 are arranged relatively, and the discharge port 3 is located at the inclined lower end position of the second screen 6, and the side of the casing 1 is located at the inclined lower end position of the first screen 5 and the guide plate 7, and is connected to a return pipe 8 arranged on the side of the casing 1 through a receiving hopper 17, and a conveying dragon (not shown in the figure) is installed in the return pipe 8, The conveying dragon is driven by a motor, and an inclined discharge pipe 18 is arranged on the top of the side of the return pipe 8, wherein the discharge pipe 18 is located above the feed port of the granulator 2. By arranging the first screen 5, the second screen 6, the guide plate 7, the receiving hopper 17 and the return pipe 8, after the beads produced by the granulator 2 enter the casing 1, the first screen 5 and the second screen 6 can screen out unqualified particles that are too large or too small in the beads, and the screened qualified particles are discharged from the casing 1 through the discharge port, and the unqualified particles enter the recovery pipe through the receiving hopper 17. The conveying dragon in the recovery pipe can re-transport these unqualified particles to the granulator 2, thereby realizing the simultaneous granulation and screening of the GPO beads, thereby improving the production efficiency of the GPO beads.

[0019] Among them, one end of the first screen 5 and the second screen 6 is rotatably arranged by the installation shaft 9, and the other end is connected to the inner wall of the casing 1 through a plurality of elastic members 10. A shaking mechanism for driving the first screen 5 and the second screen 6 to shake is also provided in the casing 1. Through such an arrangement, the screening speed of the beads is accelerated and the phenomenon of beads accumulating on the first screen 5 and the second screen 6 is avoided.

[0020] Specifically, the shaking mechanism includes a rotating shaft 11 rotatably arranged below the first sieve 5 and the second sieve 6, and a plurality of fixed disks 12 are fixedly mounted on the rotating shaft 11. A shifting ball 14 is mounted on the side wall of the fixed disk 12 through a round rod 13, and the rotation trajectory of the shifting ball 14 interferes with the flipping trajectory of the first sieve 5 and the second sieve 6.

[0021] Preferably, the two rotating shafts 11 are transmission connected via a synchronous pulley set 15 , and one of the rotating shafts 11 is driven by a motor disposed outside the housing 1 .

[0022] Specifically, when the motor drives one of the rotating shafts 11 to rotate, the two rotating shafts 11 rotate synchronously under the transmission of the synchronous belt pulley transmission group. During the rotation of the fixed disk 12 on the rotating shaft 11, the driving balls 14 at the ends of the multiple connecting rods successively drive the first screen 5 and the second screen 6 upward to flip over. With the cooperation of the elastic member 10, the first screen 5 and the second screen 6 can be driven to vibrate at a high frequency, thereby accelerating the screening of the beads.

[0023] In addition, in order to prevent the newly produced particles from sticking to each other when the beads fall onto the first screen 5 , a plurality of cooling fans 16 are provided on the inner wall of the casing 1 above the first screen 5 in this embodiment.
