Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, and in particular to a modified plastic particle vibration sorting device. Background Technology

[0002] In the plastics processing industry, modified plastic particles are widely used. Their quality and specifications play a decisive role in the performance and quality of plastic products. As a key piece of equipment in the production process of modified plastic particles, the vibration sorting device undertakes the important task of effectively separating and screening plastic particles of different sizes.

[0003] Traditional modified plastic particle vibration sorting devices mainly rely on the vibration generated by a vibrating motor to move plastic particles on a screen plate. The particles of different sizes are separated by the screen holes of different sizes on the screen plate. This method can meet the basic sorting requirements to a certain extent, but it has obvious limitations in actual production.

[0004] As the sorting process continues, some plastic particles are easily stuck in the sieve holes, causing the sieve to become clogged. Once the sieve is clogged, not only will the sorting efficiency be reduced, significantly decreasing the throughput per unit time, but the sorting accuracy will also be affected, resulting in the inability to accurately separate plastic particles of different sizes, which in turn affects the quality of the final product. Therefore, a modified plastic particle vibration sorting device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a modified plastic particle vibration sorting device to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] Preferably, a top plate is fixedly installed on the top side of each of the two fixed plates, and a first switch and a second switch are respectively provided on the opposite surfaces of the two top plates. Both the first switch and the second switch are electrically connected to the drive motor.

[0011] Preferably, a fixing rod is fixedly installed on both sides of the slider. Both fixing rods are Z-shaped, and the sides of the two fixing rods that are far apart from each other face the first switch and the second switch, respectively.

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

[0015] 1. The drive motor rotates the rotating rod, causing the slider to slide on the outside of the guide rod and the rotating rod. When the slider moves, it drives the connecting plate and the side plate to move synchronously. At the same time, the air pump of the air blowing component starts, drawing air through the air extraction pipe and delivering it to the distribution pipe through the air delivery pipe. Then, multiple nozzles facing the bottom of the screen plate spray the gas, blowing the particles blocked in the screen holes back to the upper area, thereby preventing the screen plate from becoming blocked and enabling the device to continuously and efficiently sort particles.

[0016] 2. The spring on the base plate works in conjunction with the vibration motor to drive the box to vibrate, allowing the particles to be sorted on the screen plate. In the moving assembly, the first and second switches are electrically connected to the drive motor. By pressing the switch with the fixed rod, the slider is controlled to move back and forth, so that the nozzle continuously blows air onto the screen holes, keeping the screen holes of the screen plate unobstructed. This can accurately separate particles of different sizes, avoid inaccurate sorting caused by screen plate blockage, and ensure the quality of the final product. Attached Figure Description

[0022] 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.

[0023] Reference Figure 1-4A modified plastic particle vibration sorting device includes a base plate 1, a housing 3 above the base plate 1, a vibration motor 22 fixedly connected to the bottom side of the housing 3, a sieve plate 5 inside the housing 3, the housing 3 being divided into two areas by the sieve plate 5, a through hole on one side of the housing 3 communicating with the lower area, a moving component on one side of the housing 3, a slider 10 on one side of the housing 3 via the moving component, a connecting plate 15 and a side plate 11 fixedly connected to both sides of the slider 10 respectively, the connecting plate 15 being located inside the housing 3, a diversion pipe 16 fixedly installed on the top side of the connecting plate 15, multiple nozzles 17 on the top side of the diversion pipe 16, all of the nozzles 17 facing the bottom side of the sieve plate 5, an air blowing component on the side plate 11, the air blowing component including an air pump 12 fixedly installed on the top side of the side plate 11, and air blowing... A suction pipe 13 is fixedly connected to one side of the pump 12, and an air delivery pipe 14 is fixedly connected to the other side of the pump 12. The other end of the air delivery pipe 14 is fixedly connected to one side of the diversion pipe 16 and communicates with the diversion pipe 16. With the pump 12 installed, the slider 10 starts the pump 12 synchronously during movement. The operation of the pump 12 causes the suction pipe 13 to draw in outside air, and then the drawn air is delivered to the diversion pipe 16 through the air delivery pipe 14. Since multiple nozzles 17 are provided on the top side of the diversion pipe 16, and the multiple nozzles 17 are all facing the bottom side of the screen plate 5, the gas in the diversion pipe 16 will be sprayed from the multiple nozzles 17 to the bottom side of the screen plate 5, thereby blowing the particles blocked in the screen holes to the upper area. By blowing air, the blockage of particles can be avoided, thereby improving the sorting efficiency of the screen plate 5.

[0024] Specifically, the moving component includes two fixed plates 6 fixedly installed on one side of the housing 3. A drive motor 7 is fixedly installed on one side of the right fixed plate 6. The output end of the drive motor 7 rotatably passes through the right fixed plate 6 and is fixedly installed with a rotating rod 8. The other end of the rotating rod 8 is rotatably connected to one side of the left fixed plate 6. A guide rod 9 is fixedly installed between the two fixed plates 6. The slider 10 is slidably sleeved on the outside of the guide rod 9 and the rotating rod 8. Top plates 18 are fixedly installed on the top sides of both fixed plates 6. A first switch 19 and a second switch 20 are respectively provided on the opposite sides of the two top plates 18. The first switch 19 and the second switch 20 are both electrically connected to the drive motor 7. Fixed rods 21 are fixedly installed on both sides of the slider 10. The two fixed rods 21 are both Z-shaped. The sides of the two fixed rods 21 that are far apart from each other face the first switch 19 and the second switch 20 respectively. The device has the first switch 19 and the second switch 20, which are both electrically connected to the drive motor 7. When the drive motor 7 starts and drives the slider 10 to move forward, the slider 10 moves forward. The fixed rod 21, which is fixedly installed in front of the slider 10, moves forward with the slider 10 and gradually approaches the second switch 20. When the fixed rod 21 touches the second switch 20 and presses it, the second switch 20 sends a command to the drive motor 7. The drive motor 7 then drives the rotating rod 8 to reverse. Since the slider 10 is slidably sleeved on the outside of the rotating rod 8, the reverse rotation of the rotating rod 8 will cause the slider 10 to synchronously drive the side plate 11 and the connecting plate 15 to move backward. When the slider 10 moves backward to a certain position, the fixed rod 21, which is fixedly installed on the other side of the slider 10, will press the first switch 19. At this time, the first switch 19 will send a corresponding command to the drive motor 7, and the drive motor 7 will drive the rotating rod 8 to rotate clockwise again. Thus, the slider 10 starts to move forward again. The slider 10 can reciprocate under the control of the first switch 19 and the second switch 20. At the same time, the nozzle 17 on the diversion pipe 16 will also follow the reciprocating movement of the slider 10 to continuously blow air through the blocked screen holes to ensure that the screen holes are unobstructed and maintain the efficient sorting of the device.

[0025] Specifically, four springs 2 are fixedly installed on the top side of the base plate 1, and the other end of each of the four springs 2 is fixedly connected to the bottom side of the box 3. By setting four springs 2, the box 3 can be driven to vibrate during the operation of the vibration motor 22.

[0026] Specifically, two elongated holes are provided on one side of the box body 3, and the two elongated holes are connected to two areas respectively. A first discharge port 23 and a second discharge port 24 are fixedly installed in the two elongated holes respectively. The first discharge port 23 and the second discharge port 24 are connected to the two elongated holes respectively. A feed port 4 is provided on the top side of the box body 3, and the feed port 4 is connected to the area above. By providing the first discharge port 23 and the second discharge port 24, two particles of different volumes can be discharged from the two discharge ports respectively. By providing the feed port 4, the feed port 4 is used to feed unsorted particles.

[0027] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0028] In use: Pour the particles to be sorted into the box 3 through the feed inlet 4. Then, start the vibration motor 22. Under the elastic buffering and synergistic action of multiple springs 2, the box 3 begins to vibrate. During the vibration process, smaller particles will pass through the screen holes of the screen plate 5 and fall into the lower area of ​​the box 3; larger particles will remain in the upper area of ​​the box 3. As the sorting work continues, some particles will gradually block the screen holes of the screen plate 5. At this time, start the drive motor 7. The motor drives the rotating rod 8 to rotate. The slider 10, which is slidably sleeved on the outside of the rotating rod 8, is displaced due to the rotation of the rotating rod 8, which in turn drives the connecting plates 15 and the side plates 11 on both sides to move synchronously. When the air pump 12 is started, it draws in outside air through the air extraction pipe 13 and delivers the air to the diversion pipe 16 through the air delivery pipe 14. The top side of the diversion pipe 16 is equipped with multiple nozzles 17, and these nozzles 17 are all aimed at the bottom side of the screen plate 5. Therefore, the gas in the diversion pipe 16 is ejected at high speed from the multiple nozzles 17 and blown towards the bottom side of the screen plate 5, blowing the particles blocked in the screen holes back to the upper area. This blowing and clearing method effectively avoids screen hole blockage and greatly improves the sorting efficiency of the screen plate 5. As the vibration motor 22 continues to work, the particles in the box 3 are continuously sorted. Finally, the two different sizes of particles are discharged through the first discharge port 23 and the second discharge port 24, respectively, completing the entire sorting process.
