Description

Technical Field

[0001] This utility model relates to the field of pelletizing and screening technology, and in particular to an extrusion pelletizing and screening device for engineering plastic pellet production. Background Technology

[0002] In the production process of engineering plastic particles, extrusion pelletizing and screening is a key step in ensuring product quality. The extruder extrudes molten plastic and cuts it into pellets.

[0003] In traditional extrusion pelletizing equipment, after the pellets are discharged, although engineering plastics undergo a cooling process during extrusion pelletizing, some plastics themselves have strong adhesion, making it easy for the pellets to stick together when they come into contact. However, a small number of pellets may still stick together. When these sticky particles directly enter the screening equipment, they are difficult to separate and screen effectively. On the one hand, the size of the sticky particle clusters is larger than that of normal single particles, and they will be mistakenly screened as unqualified products, resulting in a decrease in the yield. On the other hand, after the agglomerated particles enter the screen of the screening equipment, they are easy to clog the screen holes, which requires the screening equipment to be stopped frequently for cleaning, greatly reducing production efficiency. Therefore, we propose an extrusion pelletizing and screening equipment for engineering plastic pellet production. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide an extrusion pelletizing and screening device for engineering plastic particles. This device can solve the problem that in traditional extrusion pelletizing equipment, after the pellets are discharged, although the engineering plastics undergo a cooling process during the extrusion pelletizing process, some of the plastics themselves have strong viscosity, which makes it easy for the particles to stick together when they come into contact with each other. However, a small number of particles may still stick together. When these sticky particles directly enter the screening equipment, they are difficult to separate and screen effectively. On the one hand, the size of the sticky particle clusters is larger than that of normal single particles, and they will be mistakenly screened as unqualified products, resulting in a decrease in the yield. On the other hand, after the agglomerated particles enter the screen of the screening equipment, they are easy to clog the screen holes, which makes the screening equipment need to be stopped frequently for cleaning, greatly reducing the production efficiency.

The output end of the rotating motor extends into the dispersing box and is fixedly connected to the corresponding rotating shaft. The ends of the two rotating shafts away from the rotating motor extend to the outside of the dispersing box. The two toothed rings are fixedly sleeved on the outer surface of the corresponding rotating shafts and mesh with each other.

[0026] Please see Figure 1-4 This utility model provides a technical solution: an extrusion pelletizing and screening device for engineering plastic particle production, comprising:

[0027] Discharge box 1, the top of discharge box 1 is fixedly connected to discharge hopper 9, and the top of discharge hopper 9 is fixedly connected to dispersing box 6;

[0028] The particle dispersing structure is located on the dispersing box 6;

[0029] The particle dispersing structure includes a rotating motor 5, two rotating shafts 7, and two toothed rings 8. The two rotating shafts 7 are rotatably connected inside the dispersing box 6. The rotating motor 5 is fixedly installed on one side of the dispersing box 6. The output end of the rotating motor 5 extends into the dispersing box 6 and is fixedly connected to the corresponding rotating shaft 7. The ends of the two rotating shafts 7 away from the rotating motor 5 extend to the outside of the dispersing box 6. The two toothed rings 8 are fixedly sleeved on the outer surface of the corresponding rotating shaft 7. The two toothed rings 8 mesh with each other. Multiple dispersing rods 12 are fixedly connected to the outer surface of the two rotating shafts 7.

[0030] A screening cylinder 2 is fixedly connected to the top of the discharge box 1. The discharge end of the discharge hopper 9 is connected to the interior of the screening cylinder 2. A drive motor 3 is fixedly installed on one side of the screening cylinder 2. The output end of the drive motor 3 rotates and extends into the interior of the screening cylinder 2 and is fixedly connected to a feeding screw 11. Multiple screening holes 14 are opened on the outer surface of the screening cylinder 2. All multiple screening holes 14 are connected to the interior of the discharge box 1.

[0031] The internal structure of the dispersing box 6 has two guide plates 13 fixedly connected. Both guide plates 13 are located above the corresponding rotating shaft 7. The top of the dispersing box 6 is hinged with a sealing cover 15, and the top of the sealing cover 15 is fixedly connected with a handle.

[0032] A collection box 10 is slidably connected inside the discharge box 1, and the same handle is fixedly connected to the collection box 10. A plastic extruder 4 is provided on one side of the dispersing box 6. Two support frames 16 are fixedly connected to the bottom of the plastic extruder 4, and the granule extrusion end of the plastic extruder 4 extends into the interior of the dispersing box 6.

[0033] Furthermore, when using this device, during the operation of the engineering plastic particle production extrusion pelletizing and screening equipment, the plastic extruder 4 is stably placed by the support frame 16 at the bottom, and its particle extrusion end sends the produced plastic particles into the dispersing box 6. At this time, the rotating motor 5 starts, and its output end drives the rotating shaft 7 fixedly connected to it to rotate. Since the two toothed rings 8 mesh with each other, the other rotating shaft 7 also rotates in the opposite direction. Multiple dispersing rods 12 fixed on the outer surface of the rotating shaft 7 rotate synchronously to disperse the plastic particles entering the dispersing box 6. During the dispersing process, the guide plate 13 located above the rotating shaft 7 guides the plastic particles to disperse evenly.

[0034] After being broken down, the plastic particles enter the screening cylinder 2 through the discharge hopper 9. The drive motor 3 drives the feeding screw 11 to rotate, conveying the plastic particles inside the screening cylinder 2. The screening holes 14 on the outer surface of the screening cylinder 2 screen the plastic particles. Particles that meet the size requirements fall through the screening holes 14 into the collection box 10 inside the discharge box 1 for collection. Particles that do not meet the size requirements continue to be conveyed by the feeding screw 11 inside the screening cylinder 2 and are eventually discharged from the other end of the screening cylinder 2 for subsequent processing. When it is necessary to clean or maintain the inside of the breaking box 6, the sealing cover 15 hinged to the top of the breaking box 6 can be opened by the handle. When collecting qualified particles in the collection box 10 inside the discharge box 1, the handle on the collection box 10 is pulled to slide the collection box 10 out of the discharge box 1.

[0035] Two meshing rotating shafts 7 drive the dispersing rod 12 to rotate at high speed in opposite directions, forming a multi-directional and high-intensity dispersing effect. This dispersing method can completely separate the adhering particle clusters, avoiding the formation of abnormally sized particle clusters due to particle adhesion. At the same time, the guide plate 13 optimizes the particle movement trajectory, allowing the particles to be fully dispersed in the dispersing box 6, further reducing the probability of contact and adhesion between particles, ensuring the single-particle shape of the particles from the source, avoiding mis-screening problems caused by adhesion, and further improving the screening effect of plastic particles.
