Description

Technical Field

[0001] This utility model relates to the field of plastic additive granulation, specifically a granulation device for the production of plastic additives. Background Technology

[0002] Granulation in plastic additive production refers to the process of mixing, melting, extruding, cooling, and pelletizing plastic additives, such as plasticizers, stabilizers, and flame retardants, with a resin matrix to produce uniform granular products. These granules are easy to store, transport, and process (such as injection molding and extrusion molding), and are a key step in the production of modified or functionalized plastics.

[0003] In existing technologies, plastic additives can effectively improve the performance of plastics during production, processing, or use, making them more stable and robust. In the production of plastic additives, multiple additives are often mixed, melt-extruded, and then the extruded strips are transported to a water tank for cooling. Simultaneously, the strips are transferred to the worktable of a cutting and granulating equipment, where the cutting blades cut them into granules for later use. While the cutting blades effectively granulate the strips, each up-and-down movement of the blades only allows for one cut. Furthermore, if the size of the granules needs to be changed during the cutting process, it is inconvenient to move the blades and the equipment responsible for their movement as a whole. This increases the limitations of plastic additive granulation and, to some extent, affects the granulation effect. Utility Model Content

[0004] To overcome the shortcomings of existing technology, when granulating strips of plastic additives, the blade's single up-and-down movement can only achieve one cut. Furthermore, during the cutting process, when the operator needs to change the size of the granules, it is inconvenient to move the blade and the equipment responsible for its up-and-down movement as a whole. This increases the limitations in granulating plastic additives and, to some extent, affects the granulation effect. This utility model proposes a granulation device for the production of plastic additives.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a granulation device for producing plastic additives, including a granulation table, a cylinder fixedly connected to the inner cavity of the granulation table, a connecting plate fixedly connected to the output end of the cylinder, an installation frame fixedly connected to one side of the connecting plate, an adjusting granulation mechanism and a limiting component provided on the top of the granulation table, and a screening component provided on one side of the granulation table. The adjusting granulation mechanism includes a first threaded rod, one end of which is rotatably connected to the inner cavity of the mounting frame. The first threaded rod passes through one side of the mounting frame. A fixed rod is fixedly connected to the inner cavity of the mounting frame. A fixed block is fixedly connected to the inner cavity of the mounting frame. The inner cavity of the fixed block is fixedly connected to the surface of the fixed rod. A movable block is slidably connected to the surface of the fixed rod. Multiple movable blocks are provided. A diamond-shaped telescopic frame is fixedly connected to the top of the fixed block and the multiple movable blocks. A threaded ring block is fixedly connected to the inner cavity of one of the movable blocks. The inner cavity of the threaded ring block is threadedly connected to the surface of the first threaded rod. A pelletizing blade is fixedly connected to the inner cavities of the fixed block and the multiple movable blocks.

[0006] Preferably, the limiting component includes a limiting rod, one end of which is fixedly connected to the top of the granulation table. A second threaded rod is rotatably connected to the top of the granulation table. Lifting blocks are provided on the surfaces of both the limiting rod and the second threaded rod. The inner cavity of one of the lifting blocks is slidably connected to the surface of the limiting rod, and the inner cavity of the other lifting block is threadedly connected to the surface of the second threaded rod. A rotating roller is rotatably connected between the two lifting blocks.

[0007] Preferably, the screening assembly includes a servo motor, one side of which is fixedly connected to one side of the granulation table. A cam is fixedly connected to the output end of the servo motor. A second collection box is provided on one side of the granulation table. A spring is fixedly connected to the inner cavity of the second collection box. A screen is provided at one end of the spring. An arc-shaped block is fixedly connected to the bottom of the screen. A first collection box is provided on one side of the second collection box. A limit rod is fixedly connected to the inner cavity of the second collection box. The surface of the limit rod is movably connected to the inner cavity of the screen. The spring is sleeved on the surface of the limit rod.

[0008] Preferably, an auxiliary rod is fixedly connected to the inner cavity of the granulation table, and the inner cavity of the connecting plate is slidably connected to the surface of the auxiliary rod.

[0009] Preferably, each of the plurality of pelletizing blades has a first threaded hole on one side, and each of the fixed block and the plurality of movable blocks has a second threaded hole on one side. The size of the first threaded hole is the same as the size of the second threaded hole, and the inner cavities of the plurality of first threaded holes and second threaded holes are threadedly connected with bolts.

[0010] Preferably, both the second and first collection boxes are movably connected to a hinged door panel on one side, and both sides of the screen are fixedly connected to baffles.

[0011] Preferably, an inclined plate is fixedly connected to one side of the granulation table, and a guide plate is fixedly connected to one side of the screen.

[0012] The advantages of this utility model are: This invention utilizes pelletizing blades installed inside a fixed block and multiple moving blocks to achieve the simultaneous cutting of more plastic additive granules. The rotation of the first threaded rod effectively moves one of the moving blocks, and the diamond-shaped telescopic frame allows for equal spacing adjustment between the pelletizing blades, facilitating the granulation of plastic additives of different sizes. Simultaneously, the screening component allows for effective and convenient screening of the granulated plastic additives, thus significantly improving the granulation effect and efficiency. This invention solves the problem that when cutting strips of plastic additives, the blades can only perform one cut with a single up-and-down movement, and it is inconvenient to move the blades and the equipment responsible for their up-and-down movement as a whole when the size of the granules needs to be changed during the cutting process. This increases the limitations in plastic additive granulation and, to some extent, affects the granulation effect. Attached Figure Description

[0016] 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 scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. This application discloses a granulation apparatus for producing plastic additives. (Refer to...) Figure 1 and Figure 5 A granulation device for producing plastic additives includes a granulation table 1, a cylinder 2 fixedly connected to the inner cavity of the granulation table 1, a connecting plate 3 fixedly connected to the output end of the cylinder 2, a mounting bracket 4 fixedly connected to one side of the connecting plate 3, an adjusting granulation mechanism 5 and a limiting component 6 provided on the top of the granulation table 1, and a screening component 7 provided on one side of the granulation table 1. The granulation mechanism 5 includes a first threaded rod 501. One end of the first threaded rod 501 is rotatably connected to the inner cavity of the mounting frame 4. One end of the first threaded rod 501 passes through one side of the mounting frame 4. A fixed rod 502 is fixedly connected to the inner cavity of the mounting frame 4. A fixed block 503 is fixedly connected to the inner cavity of the mounting frame 4. The inner cavity of the fixed block 503 is fixedly connected to the surface of the fixed rod 502. A movable block 504 is slidably connected to the surface of the fixed rod 502. Multiple movable blocks 504 are provided. A diamond-shaped telescopic frame 505 is fixedly connected to the top of the fixed block 503 and the multiple movable blocks 504. A threaded ring block 506 is fixedly connected to the inner cavity of one of the movable blocks 504. The inner cavity of the threaded ring block 506 is threadedly connected to the surface of the first threaded rod 501. A pelletizing blade 507 is fixedly connected to the inner cavities of the fixed block 503 and the multiple movable blocks 504.

[0018] The granulation table 1 can install and connect the connecting plate 3 and the mounting frame 4 via the cylinder 2. When the cylinder 2 is operating, it can smoothly drive the connecting plate 3 and the mounting frame 4 to move up and down reciprocally through the extension and retraction of its output end. The mounting frame 4 can connect the first threaded rod 501 and the fixed rod 502. At the same time, the fixed rod 502 can realize the synchronous installation of the fixed block 503 and multiple moving blocks 504. The fixed block 503 and multiple moving blocks 504 can cooperate with each other to realize the connection of the diamond-shaped telescopic frame 505. Since the fixed block 503 and the fixed rod 502 are fixedly connected, and the multiple moving blocks... 504 and fixed rod 502 are slidably connected. Therefore, when the moving block 504 located furthest from the fixed block 503 moves, it can smoothly drive multiple moving blocks 504 to move synchronously. Moreover, due to the setting of the diamond telescopic frame 505, the moving distances of multiple moving blocks 504 are the same. At the same time, the threaded ring block 506 is installed inside the moving block 504 located furthest from the fixed block 503. This allows the first threaded rod 501 to smoothly drive the moving block 504 to move when it rotates, thereby realizing the synchronous movement of multiple moving blocks 504. Furthermore, the pelletizing blades 507 connected inside the fixed block 503 and the movable block 504 can smoothly move up and down to pelletize the cooled plastic additive strips conveyed at the top of the pelletizing table 1. Since there are multiple pelletizing blades 507, more plastic additive particles can be cut at once. At the same time, since the positions of the multiple movable blocks 504 can move at equal intervals, when the operator needs to adjust the size of the pelletized plastic additive, he only needs to rotate the first threaded rod 501 to move the multiple movable blocks 504.

[0019] Reference Figure 2 and Figure 7The limiting component 6 includes a limiting rod 601, one end of which is fixedly connected to the top of the granulation table 1. A second threaded rod 602 is rotatably connected to the top of the granulation table 1. Lifting blocks 603 are provided on the surfaces of both the limiting rod 601 and the second threaded rod 602. The inner cavity of one lifting block 603 is slidably connected to the surface of the limiting rod 601, and the inner cavity of the other lifting block 603 is threadedly connected to the surface of the second threaded rod 602. A rotating roller 604 is rotatably connected between the two lifting blocks 603. The granulation table 1 can limit the movement of the limiting rod 601. The control rod 601 is connected to the second threaded rod 602, and the lifting block 603 installed on the surface of the limiting rod 601 and the second threaded rod 602 can smoothly connect to the rotating roller 604. At the same time, the setting of the rotating roller 604 makes it less likely for the plastic additive strip cooled by the water tank to be severely warped when it is conveyed to the bottom of the pelletizing blade 507. Furthermore, the height of the rotating roller 604 can be adjusted by rotating the second threaded rod 602, so that the rotating roller 604 can accommodate plastic additive strips of more sizes and diameters.

[0020] Reference Figure 1 and Figure 3 The screening component 7 includes a servo motor 701. One side of the servo motor 701 is fixedly connected to one side of the granulation table 1. A cam 702 is fixedly connected to the output end of the servo motor 701. A second collection box 707 is provided on one side of the granulation table 1. A spring 705 is fixedly connected to the inner cavity of the second collection box 707. A screen 704 is provided at one end of the spring 705. An arc block 703 is fixedly connected to the bottom of the screen 704. A first collection box 706 is provided on one side of the second collection box 707. A limiting rod 708 is fixedly connected to the inner cavity of the second collection box 707. The surface of the limiting rod 708 is movably connected to the inner cavity of the screen 704. The spring 705 is sleeved on the surface of the limiting rod 708. Furthermore, the granulation table 1 can install and fix the cam 702 via the servo motor 701, and when the servo motor 701 is operating, it can smoothly drive the cam 702 to rotate. The screen 704 can screen the plastic additives after pelletizing, and the second collection box 707 can not only collect the plastic additive particles screened by the screen 704, but also install the spring 705 and the limiting rod 708. The limiting rod 708 can realize the placement and limiting of the screen 704. When the servo motor 701 is operating, it can smoothly push the arc-shaped block 703 at the bottom of the screen 704 upward via the cam 702. When the cam 702 rotates to a certain angle, it will stop pushing the screen 704. At this time, the screen 704 can move down by its own weight, thereby screening the granulated plastic additives. When the screen 704 moves down, it will squeeze the spring 705 by its own weight. The spring 705 can increase the vibration effect of the screen 704 by its own elasticity, thereby improving the screening effect of the screen 704. Furthermore, the spring 705 and the screen 704 are only in contact and not connected, which makes it easier for the staff to remove and replace the screen 704. In addition, the first collection box 706 can collect large plastic additives that have not fallen into the second collection box 707, and the screen 704 can be replaced by sliding connection with the limiting rod 708. When the operator adjusts the distance between the moving blocks 504 to granulate plastic additives of different sizes, the screen 704 with different aperture can also be replaced as needed.

[0021] Reference Figure 2 and Figure 6An auxiliary rod 11 is fixedly connected to the inner cavity of the granulation table 1. The inner cavity of the connecting plate 3 is slidably connected to the surface of the auxiliary rod 11. A first threaded hole 12 is provided on one side of each of the multiple pelletizing blades 507. A second threaded hole 13 is provided on one side of each of the fixed block 503 and multiple moving blocks 504. The size of the first threaded hole 12 is the same as the size of the second threaded hole 13. Bolts 14 are threadedly connected to the inner cavities of the multiple first threaded holes 12 and second threaded holes 13. The granulation table 1 can connect to the auxiliary rod 11, and the auxiliary rod 11 can connect to the connecting plate 3 through its connection with the connecting plate 3. The up-and-down movement of the connecting plate 3 serves as a limit, preventing it from wobbling or tilting during its up-and-down movement and increasing its stability. The first threaded hole 12 and the second threaded hole 13 allow the bolt 14 to effectively connect itself to the fixed block 503, multiple moving blocks 504, and the pelletizing blade 507, thus securing the pelletizing blade 507 within the fixed block 503 and multiple moving blocks 504. This makes it convenient and simple for workers to replace the pelletizing blade 507.

[0022] Reference Figure 1 and Figure 3 The second collection box 707 and the first collection box 706 are each movably connected to a hinged door plate 10 on one side. The screen 704 is fixedly connected to both sides with baffles 15. The granulation table 1 is fixedly connected to one side with an inclined plate 9. The screen 704 is fixedly connected to one side with a guide plate 8. The hinged door plate 10 allows the staff to easily and conveniently remove the plastic additive granules collected in the second collection box 707 and the first collection box 706 for subsequent packaging and processing. The inclined plate 9 allows the plastic additive granules cut by the pelletizing blade 507 to fall more smoothly to the top of the screen 704. The guide plate 8 allows the larger plastic additive granules after being screened by the screen 704 to slide smoothly into the interior of the first collection box 706. At the same time, the baffles 15 prevent the plastic additive granules from sliding off the sides of the screen 704 when it is being screened.

[0023] Working Principle: During operation, the operator places the molten, extruded, and cooled plastic additive strips (after passing through a water tank) onto the top of the granulation table 1. Because the plastic additive strips are continuously conveyed during melting and extrusion, they are continuously transported to the top of the granulation table 1. The rotating roller 604 limits the movement of the plastic additive strips during transport, reducing the likelihood of them tilting. The operator then activates cylinder 2. The continuous operation of cylinder 2 drives the connecting plate 3, mounting frame 4, and pelletizing blade 507 to reciprocate up and down, thereby achieving the pelletizing process. As the additive strips continue to granulate, the granulated plastic additive particles fall to the top of the screen 704. At this point, the operator can start the servo motor 701, which drives the cam 702 to rotate, thereby repeatedly and continuously pushing the arc block 703. This allows the screen 704 to move up and down reciprocally due to its own weight and the continuous pushing of the cam 702, thus screening the plastic additive particles. Plastic additive particles of the correct size will fall into the first collection box 706, while larger plastic additive particles will fall into the second collection box 707.

[0024] When the operator needs to adjust the granulation size of the plastic additive granules, the operator can rotate the first threaded rod 501. The first threaded rod 501 will drive one of the moving blocks 504 to move through the threaded ring block 506. Then, through the setting of the diamond telescopic frame 505, multiple moving blocks 504 can be effectively and smoothly driven to move at equal intervals. When multiple moving blocks 504 move, they can smoothly drive the pelletizing blades 507 installed inside them to move together. When the spacing of multiple moving blocks 504 is adjusted, when multiple pelletizing blades 507 move up and down again, they can cut plastic additive granules of different sizes than the original ones, thereby realizing the adjustment of the size of plastic additive granules during granulation.
