Description

Technical Field

[0001] This utility model relates to the field of plastic particle processing technology, specifically a screening device for plastic particle processing. Background Technology

[0002] Plastic particles (also known as plastic granules or resin granules) are raw materials for plastic products. They are usually in the form of tiny granules (about 1-5 mm in diameter) and are used in processing techniques such as injection molding, extrusion, and blow molding.

[0003] During the processing of plastic particles, screening devices are needed to screen the plastic particles of different sizes to ensure uniform particle size. However, in the existing screening process, large plastic particles are usually screened first, and then screened again using a small-aperture screen. This screening method is cumbersome and reduces screening efficiency. In order to solve the above problems, the inventor proposes a screening device for plastic particle processing. Utility Model Content

[0004] To address the problem that plastic particles typically require sieving large particles first and then sieving again using a small-aperture screen, making the sieving process cumbersome, this invention aims to provide a sieving device for processing plastic particles.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a screening device for processing plastic particles, comprising a screening box, wherein a first fixed frame and a second fixed frame are slidably disposed within the screening box, a first screen plate is fixedly disposed within the first fixed frame, a second screen plate is fixedly disposed within the second fixed frame, and a fixed plate is fixedly connected between the first fixed frame and the second fixed frame; an ear plate is fixedly disposed on one side of the screening box, a motor is installed within the ear plate, a guide rod is fixedly disposed at the output end of the motor, an extension rod is rotatably disposed on one side of the guide rod, a push rod is hinged to one side of the fixed plate, and the end of the push rod away from the fixed plate is rotatably sleeved on the extension rod. First, the plastic particles to be screened are poured into the first fixed frame. Then, the motor is turned on, which causes the guide rod to rotate and drives the extension rod to rotate. At the same time, one end of the push rod rotates on the outer surface of the extension rod, and the other end is hinged to one side of the fixed plate, causing the push rod to push the fixed plate to move. This causes the first fixed frame and the second fixed frame to slide back and forth synchronously in the screening box. After the plastic particles are placed in the first fixed frame, the first screen plate in the first fixed frame initially screens the large plastic particles. Medium and smaller plastic particles fall into the second fixed frame, and then the medium and smaller plastic particles are screened again by the second screen plate. This allows for the simultaneous screening of plastic particles of various sizes.

[0006] The top surfaces of both the first and second sieve plates are inclined, and the filter holes in the first sieve plate are larger than those in the second sieve plate. This allows medium and small plastics to be screened out of the first sieve plate, while larger particles are screened out and fall through the upper channel. At the same time, the second sieve plate screens out medium plastics, which fall through the lower channel. Larger and medium plastics fall into their corresponding collection boxes, while smaller particles fall into the collection frame. This allows for the separate collection of plastic particles of different sizes.

[0007] Preferably, inclined plates are fixedly installed in both the first and second fixed frames, and the inclined plates are fixedly installed on the top surfaces of the first and second sieve plates. Through grooves are opened in both the first and second fixed frames. A discharge port is fixedly installed in the screening box. The through grooves and the discharge port are interconnected. An installation plate is fixedly installed on one side of the screening box. A collection box is installed on the top surface of the installation plate. A collection frame is slidably installed in the screening box. A splicing groove is opened in the installation plate. A splicing plate is fixedly installed on the bottom surface of the collection box. The splicing plate is slidably installed in the splicing groove.

[0008] Preferably, a sliding plate is fixedly provided at the bottom end of both the first fixed frame and the second fixed frame. The sliding plate is slidably disposed in the screening box. A sliding groove is provided in the screening box. The sliding plate is slidably disposed in the sliding groove. A sliding rod is fixedly disposed in the sliding groove. The sliding plate is slidably sleeved on the outer surface of the sliding rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. The first fixed frame and the second fixed frame slide back and forth synchronously in the screening box, so that the first screen plate can initially screen the large plastic particles, while the medium and small plastics fall into the second fixed frame, and then the medium and small plastics are screened again by the second screen plate, so that multiple plastic particles of different sizes can be screened at the same time, thus improving the screening efficiency.

[0011] 2. Larger particles are sieved out through the first sieve plate, while medium-sized plastics are sieved out through the second sieve plate and fall into the channel below, causing the larger and medium-sized plastics to fall into the corresponding collection boxes. Then, the smaller particles fall into the collection frame, thus enabling the separate collection of plastic particles of different sizes. Attached Figure Description

[0020] 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.

[0021] Example: Figure 1-6As shown, this utility model provides a screening device for processing plastic particles, including a screening box 1. A first fixed frame 2 and a second fixed frame 21 are slidably disposed within the screening box 1. A first screen plate 22 is fixedly disposed within the first fixed frame 2, and a second screen plate 23 is fixedly disposed within the second fixed frame 21. A fixed plate 25 is fixedly connected between the first fixed frame 2 and the second fixed frame 21. An ear plate 3 is fixedly disposed on one side of the screening box 1. A motor 31 is installed within the ear plate 3. A guide rod 32 is fixedly disposed at the output end of the motor 31. An extension rod 33 is rotatably disposed on one side of the guide rod 32. A push rod 34 is hinged to one side of the fixed plate 25. The end of the push rod 34 away from the fixed plate 25 is rotatably sleeved on the outer surface of the extension rod 33. By turning on the motor 31, the guide rod 32 rotates, which in turn drives the extension rod 33 to rotate. At the same time, one end of the push rod 34 rotates on the outer surface of the extension rod 33, and the other end is hinged to one side of the fixed plate 25. The push rod 34 pushes the fixed plate 25 to move, causing the first fixed frame 2 and the second fixed frame 21 to slide back and forth synchronously in the screening box 1. After the plastic particles are placed in the first fixed frame 2, the first screen plate 22 in the first fixed frame 2 screens the larger plastics, while the medium and smaller plastics fall into the second fixed frame 21. Then, the medium and smaller plastics are screened again by the second screen plate 23. This allows for the simultaneous screening of multiple plastic particles of different sizes, improving screening efficiency.

[0022] Inclined plates 24 are fixedly installed in both the first fixed frame 2 and the second fixed frame 21. The inclined plates 24 are fixedly installed on the top surface of the first screen plate 22 and the second screen plate 23. Through grooves 201 are opened in both the first fixed frame 2 and the second fixed frame 21. A discharge port 102 is fixedly installed in the screening box 1. The through grooves 201 and the discharge port 102 are interconnected. An installation plate 4 is fixedly installed on one side of the screening box 1. A collection box 41 is installed on the top surface of the installation plate 4. A collection frame 43 is slidably installed in the screening box 1. A splicing groove 401 is opened in the installation plate 4. A splicing plate 42 is fixedly installed on the bottom surface of the collection box 41. The splicing plate 42 is slidably installed in the splicing groove 401.

[0023] By adopting the above technical solution, the top surfaces of the first sieve plate 22 and the second sieve plate 23 are both inclined surfaces, and the filter holes in the first sieve plate 22 are larger than those in the second sieve plate 23. This allows medium and small plastics to be screened out from the first sieve plate 22, while larger particles are screened out from the first sieve plate 22 and fall into the upper channel 201. At the same time, the second sieve plate 23 screens out medium plastics, which fall into the lower channel 201, and the larger and medium plastics fall into the corresponding collection boxes 41. Then, the smaller particles fall into the collection frame 43, thereby enabling the separate collection of plastic particles of different sizes.

[0024] Slide plate 26 is fixedly provided at the bottom of both the first fixed frame 2 and the second fixed frame 21. Slide plate 26 is slidably disposed in the screening box 1. A sliding groove 101 is provided in the screening box 1. Slide plate 26 is slidably disposed in the sliding groove 101. A sliding rod 11 is fixedly disposed in the sliding groove 101. Slide plate 26 is slidably sleeved on the outer surface of sliding rod 11.

[0025] By adopting the above technical solution, when the first fixed frame 2 and the second fixed frame 21 slide back and forth, the slide plate 26 is driven to slide on the outer surface of the slide rod 11 and slide in the slide groove 101, thereby assisting the first fixed frame 2 and the second fixed frame 21 to slide.

[0026] Working principle: First, the plastic particles to be screened are poured into the first fixed frame 2. Then, the motor 31 is turned on, which causes the guide rod 32 to rotate and drive the extension rod 33 to rotate. At the same time, one end of the push rod 34 rotates on the outer surface of the extension rod 33, and the other end is hinged to one side of the fixed plate 25, which pushes the fixed plate 25 to move. This causes the first fixed frame 2 and the second fixed frame 21 to slide back and forth synchronously in the screening box 1. After the plastic particles are placed in the first fixed frame 2, the first screen plate 22 in the first fixed frame 2 initially screens the large plastic particles. Medium and smaller plastic particles fall into the second fixed frame 21, and then the medium and smaller plastic particles are screened again by the second screen plate 23. Thus, multiple plastic particles of different sizes can be screened at the same time.

[0027] The top surfaces of the first sieve plate 22 and the second sieve plate 23 are both inclined surfaces, and the filter holes in the first sieve plate 22 are larger than those in the second sieve plate 23. This allows medium and small plastics to be screened out from the first sieve plate 22, while larger particles are screened out from the first sieve plate 22 and fall into the upper channel 201. At the same time, the second sieve plate 23 screens out medium plastics, which fall into the lower channel 201. Larger and medium plastics fall into the corresponding collection boxes 41, while smaller particles fall into the collection frame 43. This allows for the separate collection of plastic particles of different sizes.
