Description

Technical Field

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

[0002] Plastic granules are widely used in industrial production processes such as injection molding, extrusion, and blow molding. Their purity, particle size uniformity, and dryness directly affect the quality of the final product. During the production of plastic granules, raw materials often experience problems such as clumping, moisture, or the introduction of metallic impurities due to transportation, storage, or production processes. In the field of plastic granule processing, traditional sorting methods often employ simple mechanical screening, where plastic granules are directly poured onto a vibrating screen for single-dimensional size sorting.

[0003] While this basic screening method is simple to operate, it has obvious limitations. For example, it is difficult to fully disperse agglomerated particles, which affects the subsequent screening and drying effects; damp particles tend to stick together during screening, causing sieve holes to become clogged and reducing sorting efficiency; magnetic impurities (such as metal fragments) are difficult to remove dynamically, and residual impurities may damage processing equipment or affect the quality of the finished product. Therefore, an automatic sorting device for plastic particle processing is needed to solve the existing shortcomings. Utility Model Content

[0004] The purpose of this invention is to develop an intelligent automatic plastic particle sorting device that can simultaneously achieve dispersing, drying, impurity removal and precise sieving, in order to solve the problems of clumping, screen blockage and impurity residue in traditional sorting methods.

[0005] To address the aforementioned technical problems, this application provides an automatic sorting device for processing plastic granules, comprising support plates symmetrically arranged, a processing box fixedly connected to the top of the support plates, feed pipes fixedly connected to both sides of the top of the processing box, an air suction machine fixedly connected to the top of the processing box, and several heating pipes fixedly connected to both sides of the interior of the processing box. Screening plates are movably connected to opposite sides of the support plates. A dispersing component is provided on the processing box to break up clumps of plastic. A spreading magnetic adsorption component is provided between the support plates to evenly disperse the plastic granules and adsorb magnetic particles within them.

[0006] Furthermore, the agitation assembly includes a first sprocket, a second sprocket, a chain, a drive rod, and agitators. The agitators are arranged in a linear array. The ends of the agitators are all fixedly connected to the first sprocket. The end of the drive rod is fixedly connected to the second sprocket. The chain is sleeved on the outside of the first and second sprockets, and the first sprocket, the second sprocket, and the chain are arranged in a linear array.

[0007] Furthermore, the agitation component includes a first swirl cylinder, a second swirl cylinder, and an agitation cylinder. One end of the agitation cylinder is fixedly connected to the first swirl cylinder, and the other end of the agitation cylinder is fixedly connected to the second swirl cylinder. The agitation cylinder is movably connected to the inside of the processing box through the first swirl cylinder and the second swirl cylinder.

[0008] Furthermore, each of the first sprockets is fixedly connected to the outside of the first rotating cylinder, and both the first and second sprockets are located on the outside of the processing box. The drive rod is movably connected to the inside of the processing box, and a servo motor is fixedly connected to the outside of the processing box, with the output end of the servo motor fixedly connected to the end of the drive rod.

[0009] Furthermore, the spreading magnetic suction assembly includes a control rod, a sleeve, magnetic suction cups, connecting blocks, and a collection chamber. Several magnetic suction cups are fixedly connected to the outside of the sleeve, and the magnetic suction cups are distributed in a linear array. The control rod passes through the sleeve and is movably connected to the sleeve. Connecting blocks are fixedly connected to both ends of the collection chamber, and the collection chamber is in movable contact with the magnetic suction cups.

[0010] Furthermore, the spreading magnetic attraction assembly also includes support blocks and a vibration motor. The support blocks are symmetrically arranged and each support block is L-shaped.

[0012] This utility model has at least the following beneficial effects:

[0013] I. This utility model, through its multi-stage mixing drum and heating tube assembly, effectively breaks up clumps of plastic granules and removes moisture during the heating process. The continuous action of the strip-shaped structure on the mixing drum ensures thorough dispersion of the plastic granules, while the heat generated by the heating tube evaporates the moisture, which is then expelled by the suction fan, thus achieving rapid drying of the plastic granules. This design significantly improves processing efficiency and avoids the uneven screening problems caused by clumping and moisture in traditional methods.

[0014] II. This utility model, through the installation of a spreading magnetic suction component, utilizes the rotation and reciprocating motion of the magnetic suction disk to not only evenly spread plastic granules on the screening plate, improving the screening effect, but also simultaneously adsorb magnetic impurities. As the magnetic suction disk rotates, the adsorbed magnetic granules are scraped into a moving collection chamber, achieving dynamic removal of impurities. Combined with the multi-stage screening function of the vibrating screening plate, the final output is pure plastic granules of different particle sizes, solving the problem of incomplete screening caused by impurity residue and particle accumulation in traditional sorting devices.

[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] like Figure 1-4As shown, this utility model provides a technical solution: an automatic sorting device for processing plastic granules, including a support plate 1, the support plates 1 are symmetrically arranged, a processing box 2 is fixedly connected to the top of the support plate 1, a feed pipe 3 is fixedly connected to both sides of the top of the processing box 2, a suction machine 4 is fixedly connected to the top of the processing box 2, and several heating pipes are fixedly connected to both sides of the interior of the processing box 2 for heating the plastic granules and removing moisture. A screening plate 5 is movably connected to the opposite side of the support plate 1. A stirring component 6 is provided on the processing box 2 for breaking up agglomerated plastic clumps. A spreading magnetic adsorption component 7 is provided between the support plates 1 for dispersing the plastic granules evenly and adsorbing magnetic particles.

[0022] First, the screening plate 5 consists of two screen plates, one above the other, and each screen plate has a discharge port at its front end for discharging particles of different sizes. The screening plate 5 is usually controlled by a brake motor, which causes the screening plate 5 to vibrate, so that the plastic particles fall continuously from the screen holes as they move forward, thus completing the screening process and thus forming the complete technical solution.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the agitation assembly 6 includes a first sprocket 601, a second sprocket 602, a chain belt 603, a drive rod 604, and agitating components. The agitating components are arranged in a linear array. Each agitating component is fixedly connected to a first sprocket 601 at its end. The end of the drive rod 604 is fixedly connected to a second sprocket 602. The chain belt 603 is sleeved on the outside of the first sprocket 601 and the second sprocket 602. The agitating components include a first rotating cylinder 605, a second rotating cylinder 606, and an agitating cylinder 607. One end of the agitating cylinder 607 is fixedly connected to the first rotating cylinder 605. Furthermore, the other end of the mixing cylinder 607 is fixedly connected to the rotating cylinder 606. The mixing cylinder 607 is movably connected to the inside of the processing box 2 through the rotating cylinder 605 and the rotating cylinder 606. The sprocket 601 is fixedly connected to the outside of the rotating cylinder 605. The sprocket 601 and the rotating cylinder 602 are both located on the outside of the processing box 2. The drive rod 604 is movably connected to the inside of the processing box 2. The outside of the processing box 2 is fixedly connected to the servo motor 8, and the output end of the servo motor 8 is fixedly connected to the end of the drive rod 604. In this application, there are three sprockets 601.

[0024] In use, plastic granules are first poured into the interior of the processing chamber 2 through the two feed pipes 3 at the top of the processing chamber 2. The servo motor 8 is started, which drives the drive rod 604 to rotate, causing the sprocket 602 to rotate synchronously. The chain belt 603 is controlled to rotate, causing the other three sprockets 601 to rotate synchronously. This causes the rotating drum 605, the mixing drum 607, and the rotating drum 606 to rotate synchronously. The mixing drum 607 is made of several strip-shaped structures (mixing strips). As the plastic granules fall, the clumps of plastic granules collide with the mixing strips and are thus broken up. After continuous mixing by the three sets of mixing strips, the mixed plastic granules generate water vapor under the action of the heating tube. This vapor moves upward along the interior of the processing chamber 2 and is discharged from the interior of the processing chamber 2 under the action of the suction fan 4, thus drying the plastic granules. Then, the broken granules slide from the bottom of the processing chamber 2 to the top of the screening plate 5.

[0025] like Figure 1 and Figure 4 As shown, the spreading magnetic suction assembly 7 includes a control rod 701, a sleeve 702, magnetic chucks 703, connecting blocks 704, and a collection chamber 705. Several magnetic chucks 703 are fixedly connected to the outer side of the sleeve 702, and the magnetic chucks 703 are arranged in a linear array. The control rod 701 passes through the sleeve 702 and is movably connected to the sleeve 702. Connecting blocks 704 are fixedly connected to both ends of the collection chamber 705, and the collection chamber 705 is in movable contact with the magnetic chucks 703. The spreading magnetic suction assembly 7 also includes support blocks 706 and a vibration motor 707. The support blocks 706 are symmetrically arranged. All support blocks 706 are L-shaped. The top of each support block 706 is movably connected to the support plate 1. The ends of each sleeve 702 are rotatably connected to the support block 706 via bearings. Each connecting block 704 is fixedly connected to the support block 706. A vibration motor 707 is fixedly connected to the outside of the support plate 1, and the output end of the vibration motor 707 is fixedly connected to the top of the support block 706. The ends of each control rod 701 are movably connected to the support plate 1 via bearings. A second servo motor 9 is fixedly connected to the outside of the support plate 1, and the output end of the second servo motor 9 is fixedly connected to the end of the control rod 701.

[0026] Servo motor 9 is started, causing control lever 701 to rotate, which drives sleeve 702 and magnetic chuck 703 to rotate synchronously. Vibration motor 707 is started, controlling support block 706 to move back and forth, which in turn drives sleeve 702 to move back and forth during rotation. As plastic granules move forward along screening plate 5, the reciprocating magnetic chuck 703 spreads the piled plastic granules evenly on the surface of screening plate 5, improving the screening efficiency of plastic granules and preventing accumulation that makes it difficult for upper layer plastic granules to pass through the sieve holes. In addition, magnetic chuck 703 can adsorb magnetic substances in plastic granules. Under the action of connecting block 704, collection bin 705 moves back and forth synchronously with support block 706. During the rotation of magnetic chuck 703, the magnetic particles adsorbed on its surface are scraped into the interior of collection bin 705, thereby continuously collecting magnetic particles in plastic granules and preventing them from remaining in the plastic granules. Under the action of screening plate 5, plastic granules are screened into particles of different sizes and collected.

[0027] Working Principle: During operation, plastic granules are first poured into the processing chamber 2 through the two feed pipes 3 at the top. Servo motor 8 is activated, driving drive rod 604 to rotate, causing sprocket 602 to rotate synchronously. This controls the chain belt 603 to rotate, causing the other three sprockets 601 to rotate synchronously, resulting in the simultaneous rotation of rotating drum 605, stirring drum 607, and rotating drum 606. Stirring drum 607 is made of several strip-shaped structures (stirring bars). As the plastic granules fall, the clumps collide with the stirring bars and are broken up. After continuous stirring by the three sets of stirring bars, the broken plastic granules, under the action of the heating tube, generate water vapor, which moves upwards along the inside of the processing chamber 2 and is discharged from the inside of the processing chamber 2 under the action of the suction fan, thus drying the plastic granules. The broken granules then slide from the bottom of the processing chamber 2 to the top of the screening plate 5. Servo motor 9 is then activated, causing the control rod... Rotation of 701 causes the sleeve 702 and magnetic chuck 703 to rotate synchronously, starting the vibration motor 707 and controlling the support block 706 to reciprocate. This causes the sleeve 702 to reciprocate during rotation. As the plastic granules move forward along the screening plate 5, the reciprocating magnetic chuck 703 spreads the piled plastic granules evenly onto the surface of the screening plate 5, improving the screening efficiency of the plastic granules and preventing accumulation that would make it difficult for the upper layer of plastic granules to pass through the sieve holes. Furthermore, the magnetic chuck 703 can attract magnetic substances in the plastic granules. Under the action of the connecting block 704, the collection chamber 705 reciprocates synchronously with the support block 706. During the rotation of the magnetic chuck 703, the magnetic particles attracted to its surface are scraped into the interior of the collection chamber 705, thereby continuously collecting the magnetic particles in the plastic granules and preventing them from remaining in the plastic granules. Under the action of the screening plate 5, the plastic granules are screened into particles of different sizes and collected.
