Description

Technical Field

[0001] This utility model relates to the field of plastic powder filtration technology, specifically a plastic powder screening and filtration mechanism. Background Technology

[0002] Powder coating, also known as plastic powder, is a material used in powder coating processes. It is typically formed by grinding plastic sheets or granules into a powder. After being heated to a high temperature, the powder is sprayed onto the material surface using compressed air, forming a uniform coating. Powder coatings are widely used in automotive manufacturing, electronics, medical devices, building materials, and many other fields. As a thermosetting powder coating for electrostatic spraying, powder coating offers good results, low cost, accurate colors, and an aesthetically pleasing appearance, making it widely popular in the market. However, tiny particles in the powder coating can affect the overall quality of the coating. Generally, the finer the particles, the smoother the surface of the coating and the stronger the adhesion. Therefore, removing tiny particles through screening can improve the smoothness and evenness of the coating, thereby enhancing its overall quality.

[0003] A Chinese patent (publication number CN216760460U) was found, disclosing a plastic powder granule screening device. The key technical points are: a plastic powder granule screening device includes a base and a box body disposed above the base. The box body has an inlet. A screening component is disposed inside the box body, including a screening frame fixedly connected to the box body. The screening frame has screening holes for screening plastic granules. A first discharge port is located on one side of the box body, and a second discharge port is located on the other side of the box body. The first discharge port is located above the screening frame, and the second discharge port is located below the first discharge port. A driving component for driving the box body to vibrate is disposed between the box body and the base.

[0004] Screening for tiny particles in plastic powder is crucial for improving coating quality, optimizing spraying effects, enhancing electrical conductivity and powder application rate, improving storage stability, and increasing powder recovery rate. However, in general plastic powder screening and filtration systems, the filter holes can become clogged during the filtration process, leading to a decrease in screening efficiency and impacting work efficiency. Manually cleaning clogged filter holes is time-consuming, labor-intensive, and difficult, increasing the workload of workers and affecting the screening effect. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-7 This utility model provides a plastic powder screening and filtering mechanism:

[0023] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7As shown, a plastic powder screening and filtering mechanism includes a screening cylinder 1. A motor 4 is fixedly installed on the top of the screening cylinder 1. An opening is provided on the top of the screening cylinder 1, which matches the rotating end of the motor 4. A rotating shaft 2 is connected to the rotating end of the motor 4. Stirring rods 3 are fixedly installed on both sides of the bottom of the rotating shaft 2. A feed inlet 5 connected to the top of the screening cylinder 1 is fixedly installed. A dredging plate 6 is provided on both sides of the screening cylinder 1. An electric telescopic rod 7 is fixedly installed on one side of the dredging plate 6. A groove is provided on the inner side of the dredging plate 6. Multiple telescopic dredging rods 8 are fixedly installed inside the groove. The telescopic dredging rods 8 match the filter holes on the screening cylinder 1.

[0024] A support column 9 is fixedly installed on one side of the electric telescopic rod 7. A support column 10 is fixedly installed on the top of the support column 9. A servo motor 11 is fixedly installed on one side of the support column 10. A rotating shaft 12 is connected to the rotating end of the servo motor 11. A turntable 13 is fixedly installed at the bottom of the turntable 13. Two connecting columns 21 are fixedly installed at the bottom edge of the turntable 13. The connecting columns 21 are fixedly installed on the top of the screening cylinder 1. A base plate 14 is fixedly installed at the bottom of the support column 9. A limiting groove is opened at the bottom of the base plate 14. A sliding column 22 is fixedly installed at the bottom of the unblocking plate 6. The sliding column 22 is slidably installed on the limiting groove.

[0025] When a filter hole is blocked, the operator controls the servo motor 11 to start rotating the screening cylinder 1 via the control panel 19. The operator can use the servo motor 11 to precisely align the blocked filter hole with the telescopic unblocking rod 8 on the unblocking plate 6. The operator controls the telescopic unblocking rod 8 to retract into the unblocking plate 6 via the control panel 19. At this time, the operator runs the electric telescopic rod 7, causing the sliding column 22 to slide within the limiting groove, so that the unblocking plates 6 on both sides close and fit against the outer wall of the screening cylinder 1. At this time, the telescopic unblocking rod 8 begins to extend and insert into the filter hole to unblock the filter hole. After filtration is completed, the operator can collect the plastic powder inside the collection bin 15.

[0026] The bottom plate 14 is fixedly installed with a material collection bin 15, and the bottom of the screening cylinder 1 is provided with a discharge port. The material collection bin 15 is matched with the discharge port, and the telescopic unblocking rod 8 is in contact with the unblocking plate 6 when it is not telescopic.

[0027] The operator feeds plastic powder into the screening cylinder 1 through the feed inlet 5, and then turns on the servo motor 11 through the control panel 19, which drives the rotating shaft 12 to rotate, causing the turntable 13 to start rotating. The connecting column 21 on the turntable 13 causes the screening cylinder 1 to start rotating. Then, the motor 4 is turned on, which makes the rotating shaft 2 rotate, driving the stirring rod 3 to stir. The stirring rod 3 can prevent the plastic powder from settling to the bottom and avoid blockage. The motor 4 rotates in the opposite direction to the servo motor 11. Due to the centrifugal force, the larger plastic powder will be thrown out, while the smaller plastic powder will be retained in the screening cylinder 1. The larger plastic powder is thrown out through the filter holes on the screening cylinder 1 and hits the unblocking plate 6.

[0028] A control panel 19 is fixedly installed on one side of the collection bin 15, and a power supply 20 is fixedly installed on one side of the collection bin 15. The power supply 20 is electrically connected to the motor 4, the electric telescopic rod 7, the telescopic drain cleaner 8, the servo motor 11, and the control panel 19. The control panel 19 is signal connected to the motor 4, the electric telescopic rod 7, the telescopic drain cleaner 8, and the servo motor 11.

[0029] Staff can control motor 4, electric telescopic rod 7, telescopic drain cleaning rod 8, and servo motor 11 through control panel 19, which is convenient for staff to operate.

[0030] Higher quality plastic powder is normal plastic powder, while lower quality plastic powder needs to be sieved out.

[0031] See Figure 1 , Figure 6 The bottom of the screening cylinder 1 is fixedly installed with a limiting slide groove 16, and the bottom of the screening cylinder 1 is provided with a bottom cover 17. The bottom cover 17 matches the discharge port and slides in the limiting slide groove 16. A handle 18 is fixedly installed on one side of the bottom cover 17.

[0032] Smaller plastic powder particles remain in the screening cylinder 1. Workers can hold the handle 18 to slide the bottom cover 17 out of the limiting groove 16, allowing the smaller plastic powder particles to fall into the collection bin 15 for easy subsequent processing.

[0033] Working principle: The operator feeds plastic powder into the screening cylinder 1 through the feed inlet 5, and then starts the screening cylinder 1 to rotate through the control panel 19. The motor 4 is then turned on to drive the stirring rod 3 to agitate. When a filter hole is blocked, the operator starts the screening cylinder 1 to rotate through the control panel 19, so that the blocked filter hole is precisely aligned with the telescopic unblocking rod 8 on the unblocking plate 6. The telescopic unblocking rod 8 is then controlled to retract into the unblocking plate 6. At this time, the operator runs the electric telescopic rod 7 to close the unblocking plates 6 on both sides, so that they fit against the outer wall of the screening cylinder 1. At this time, the telescopic unblocking rod 8 begins to extend and insert into the filter hole to unblock the filter hole. After filtration is completed, the operator can collect the plastic powder inside the collection bin 15.

[0034] Smaller plastic powder particles remain in the screening cylinder 1. Workers can hold the handle 18 to slide the bottom cover 17 out of the limiting groove 16, allowing the smaller plastic powder particles to fall into the collection bin 15 for easy subsequent processing.
