Description

Technical Field

[0001] This utility model belongs to the technical field of plastic granulation equipment, and more specifically, it relates to a granulation device for modified plastic materials. Background Technology

[0002] Modified plastics refer to plastic products that have been processed through methods such as filling, blending, and reinforcement on the basis of general-purpose plastics and engineering plastics, thereby improving their properties such as flame retardancy, strength, impact resistance, and toughness. Granulation is a key step in the production and processing of modified plastic materials, and it usually requires the use of a granulator.

[0003] Existing granulators lack a corresponding buffer mechanism on the scraper, which directly damages the scraper when it collides hard with materials, molds, or other components. Therefore, this paper studies and improves the existing structure and addresses its shortcomings to provide a granulation device for modified plastic materials, aiming to achieve greater practical value.

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a granulation device for modified plastic materials, including a granulator body 1. A feed hopper 2 is fixedly installed at the top of the granulator body 1, and a top plate 3 is symmetrically rotatably connected inside the feed hopper 2. A discharge hopper 4 is fixedly installed on one side of the granulator body 1. A drive motor 5 is fixedly installed on one side of the granulator body 1 via a support rod. The output end of the drive motor 5 passes through the interior of the discharge hopper 4 and is connected to a rotating disk 6. Three sets of clamping seats 7 are installed at equal angles on the outer side of the rotating disk 6. A scraper 8 is slidably connected inside each clamping seat 7. Three sets of mounting seats 9 corresponding to the clamping seats 7 are installed at equal angles on the outer side of the rotating disk 6. Two sets of telescopic rods 10 are vertically installed inside each mounting seat 9. A fixing plate 11 is installed at one end of the two sets of telescopic rods 10 on the same side. The fixing plate 11 is slidably connected to the scraper 8.

[0025] The feed hopper 2 has two sets of arc-shaped grooves symmetrically arranged on both sides. Guide rods 12 are slidably connected inside each arc-shaped groove. One end of each guide rod 12 is fixedly connected to the top plate 3. A bottom plate 13 is fixedly installed on both sides of the feed hopper 2. Two sets of electric push cylinders 14 are vertically installed on the top of each bottom plate 13. Positioning plates 15 are fixedly installed on the output ends of the two sets of electric push cylinders 14 on the same side. Waist-shaped grooves 16 are opened on both sides of the two sets of positioning plates 15. The other end of each guide rod 12 passes through the corresponding waist-shaped groove 16 and is slidably connected to it. This allows the top of the feed hopper 2 to be sealed when it is not in use, thereby preventing external impurities or dust from entering the interior of the granulator body 1 and ensuring the production and processing quality of the granulator body 1.

[0026] Each guide rod 12 has a limiting ring 17 fixedly installed on its outer side, and one side of each limiting ring 17 is in contact with the positioning plate 15, which facilitates the restriction of the movement of the guide rod 12 and prevents it from deviating.

[0027] The scraper 8 has two sets of waist-shaped grooves 18 on one side, and the clamping seat 7 has a fixing groove corresponding to the waist-shaped grooves 18 on the outer side. Locking pins 19 are installed inside the two sets of fixing grooves. The locking pins 19 are horizontally slidably connected inside the waist-shaped grooves 18. A through hole is opened on one side of the locking pin 19, and an R-shaped pin 20 is installed inside the through hole, so that the locking pins 19 can be quickly disassembled and the scraper 8 can slide.

[0030] The working principle of this embodiment:

[0031] When the granulator body 1 needs to be fed, the electric pusher cylinder 14 is activated first. The output end of the electric pusher cylinder 14 drives the positioning plate 15 to move upward. With the cooperation of the waist-shaped groove 16 on one side of the positioning plate 15 and the corresponding arc-shaped groove on the side of the feeding hopper 2, the guide rods 12 on both sides of the top plate 3 slide upward along their outer contours, thereby unfolding the top plate 3 which is fixedly connected to the guide rods 12, so that material can be added into the granulator body 1. After feeding is completed, the electric pusher cylinder 14 is activated again to drive the top plate 3 to move downward, thereby completing the sealing of the feeding hopper 2 and preventing external impurities or dust from entering the interior of the granulator body 1. When the scraper 8 is in use, the telescopic rod 10 and the spring With the cooperation of spring 22, the scraper 8 slides inside the clamping seat 7, thereby avoiding direct hard collision between the scraper and mold 8. When the scraper 8 needs to be replaced, first pull out the R-pin 20 from one side of the locking pin 19 and pull out the locking pin 19 from one side of the clamping seat 7. Then remove the scraper 8 along the opening direction of the clamping seat 7. Then place the new scraper 8 at the opening of the clamping seat 7. While placing it, make the slider 21 on one side of the scraper 8 engage with the fixing plate 11 on one side of the telescopic rod 10. Then insert the locking pin 19 into the fixing groove on one side of the clamping seat 7 and insert the R-pin 20 into the locking pin 19 to complete the fixing of the locking pin 19.
