Description

Technical Field

[0001] This utility model relates to the field of nylon modified particle granulation technology, and in particular to a continuous granulation processing equipment for nylon modified particles. Background Technology

[0002] Nylon modified granules are granular materials made by adding various modifiers to nylon for physical or chemical modification. The modification process in nylon modified granules refers to improving the properties of nylon so that it can better meet various specific application requirements. After reinforcement and modification, the mechanical properties of nylon granules, such as tensile strength, flexural strength and impact strength, are significantly improved, and some modified nylon granules have better heat resistance.

[0003] The processing and preparation of nylon modified granules requires the use of granulation equipment. The mixed raw materials are added into the granulator through the feed hopper, and the feeding screw is driven by the drive system to rotate, so that the feeding screw conveys the raw materials to the granulation template. The raw materials are heated by the heating system. After being heated and melted, the raw materials come into contact with the granulation template, and then the extruded raw materials are granulated by the cutter. The cooled granules are nylon modified granules.

[0004] However, in the granulation process of modified nylon granules, the raw materials need to be mixed by a mixer and stirred by a high-speed rotating stirring blade. After stirring, the raw materials are added into the continuous granulation processing equipment for modified nylon granules. The raw materials need to be transferred from the mixer to the granulator, which makes the entire production process not continuous. Therefore, its degree of mechanization is not high. Based on the above problems, this application proposes a continuous granulation processing equipment for modified nylon granules. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a continuous granulation processing equipment for modified nylon granules, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The continuous granulation processing equipment for modified nylon granules uses a stirring motor that drives the stirring paddle to rotate via a stirring shaft, which can mix unmixed raw materials. At the same time, the stirring motor rotates in the opposite direction via the stirring shaft, causing the connecting component to drive the sealing plate to rotate, so that the mixed raw materials enter the bottom of the fixed plate through the opening. Thus, when the mixed raw materials enter the granulator body, the unmixed raw materials can be stirred and mixed, and the raw materials at the bottom of the fixed plate can be replenished in a timely manner, which facilitates the ideal granulation of modified nylon granules, making the granulation equipment more automated and enabling the entire production to proceed continuously.

[0022] 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.

[0023] Reference Figure 1-6 A continuous granulation processing device for modified nylon granules includes a mounting base plate 1, a granulator body 24 fixedly mounted on the top of the mounting base plate 1, a weighable mounting frame mounted on the top of the mounting base plate 1, a mixing feed box 6 mounted on the top of the mounting base plate 1 via the weighable mounting frame, a support plate 7 fixedly mounted on the top of the mixing feed box 6, a stirring motor 8 fixedly mounted on the top of the support plate 7, a stirring shaft 9 fixedly mounted on the output end of the stirring motor 8, a stirring paddle 10 fixedly mounted on the surface of the stirring shaft 9, a fixing plate 11 fixedly mounted inside the mixing feed box 6, a sealing plate 12 overlapping the top of the fixing plate 11, and a connecting assembly between the top of the sealing plate 12 and the bottom end of the stirring shaft 9, the connecting assembly including a fixed mounting plate... An upper ratchet sleeve 13 is fixedly mounted on the bottom of the stirring shaft 9, and an isolation cover 25 is fixedly mounted on the top of the sealing plate 12. The connecting component is located inside the isolation cover 25. The isolation cover 25 can seal the connecting component, preventing raw materials from entering the connecting component and causing it to malfunction. A lower ratchet sleeve 14 is overlapped inside the upper ratchet sleeve 13. A limit protrusion 15 is fixedly mounted inside the lower ratchet sleeve 14. A spring 16 is fixedly mounted at the bottom of the lower ratchet sleeve 14. A connecting circular plate 17 is fixedly mounted at the bottom of the spring 16. A rotating shaft 18 is fixedly mounted on the surface of the connecting circular plate 17. The rotating shaft 18 is rotatably mounted inside the fixed plate 11, and the sealing plate 12 is fixedly mounted on the surface of the rotating shaft 18. A limit is provided on the surface of the rotating shaft 18. There are four grooves 19, four limiting protrusions 15, and four limiting grooves 19, all arranged in a circular array to distribute the force applied during rotation and prevent individual limiting protrusions 15 from breaking due to excessive force. The limiting grooves 19 are slidably connected to the limiting protrusions 15. The lower ratchet sleeve 14 is slidably mounted on the surface of the rotating shaft 18. When the stirring shaft 9 rotates clockwise, it drives the upper ratchet sleeve 13 to rotate, causing the upper ratchet sleeve 13 to move along the inclined surface of the lower ratchet sleeve 14. This pushes the lower ratchet sleeve 14 downward, compressing the spring 16. This prevents the rotating shaft 18 from moving during the mixing process. The mixing shaft 9 will drive the sealing plate 12 to move. After the raw materials are mixed, the mixing shaft 9 drives the lower ratchet sleeve 14 to rotate through the upper ratchet sleeve 13. The lower ratchet sleeve 14 drives the rotating shaft 18 to rotate through the limiting protrusion 15 and the limiting groove 19. This causes the rotating shaft 18 to drive the sealing plate 12 to rotate, so that the sealing plate 12 no longer blocks the opening of the fixed plate 11. The mixed raw materials fall below the fixed plate 11 and enter the granulator body 24 through the discharge pipe of the mixing discharge box 6. This prevents the raw materials from being transferred to the feed hopper of the granulator body 24 after being mixed in the mixer. A pelletizing component is provided on the right side of the granulator body 24. The feed pipe of the granulator body 24 is connected to the discharge pipe of the mixing discharge box 6.

[0024] Specifically, the weighable mounting frame includes four weighing sensors 2 fixedly mounted on the top of the mounting base plate 1, which are symmetrically distributed. A T-shaped mounting plate 3 is fixedly mounted on the top of the weighing sensors 2. Fixing blocks 4 are fixedly mounted between the opposing surfaces of the T-shaped mounting plates 3. A mounting ring 5 is fixedly mounted on the side of the fixing block 4 away from the T-shaped mounting plate 3. The mounting ring 5 is fixedly mounted on the surface of the mixing feed box 6. When the raw material is added into the mixing feed box 6, the mixing feed box 6 will apply gravity to the T-shaped mounting plate 3 through the mounting ring 5 and the fixing blocks 4, and then apply the final gravity to the weighing sensors 2 through the T-shaped mounting plate 3. The weighing sensors 2 weigh the raw material in the mixing feed box 6. When the added unmixed raw material does not change, as the mixed raw material enters the granulator body 24, the weighing sensors 2 can weigh the less raw material. When the raw material is reduced to a preset value, it means that the mixed raw material can be added below the fixing plate 11.

[0025] Specifically, the pelletizing assembly includes a connecting frame 20 fixedly installed on the right side of the pelletizer body 24. A servo motor 21 is fixedly installed on the right side of the connecting frame 20. An installation sleeve 22 is fixedly installed at the output end of the servo motor 21. A pelletizing blade 23 is fixedly installed on the surface of the installation sleeve 22. The servo motor 21 drives the installation sleeve 22 at the output end to rotate, so that the installation sleeve 22 drives the pelletizing blade 23 to move, so that the pelletizing blade 23 pelletizes the extruded raw material, thereby facilitating the preparation of nylon modified granules. The length of the nylon modified granules can be controlled by controlling the moving speed of the pelletizing blade 23 through the servo motor 21.

[0026] This continuous granulation processing equipment for modified nylon granules is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: The raw materials required for the preparation of nylon modified granules are added into the mixing and feeding box 6. The stirring motor 8 drives the output end to rotate the stirring shaft 9, which in turn drives the stirring paddle 10 to mix the raw materials. When the mixed raw materials enter the granulator body 24 below the fixed plate 11, the weight of the raw materials inside the mixing and feeding box 6 is detected by the weighing sensor 2. When the weight of the raw materials in the mixing and feeding box 6 is lower than the preset value, the stirring motor 8 drives the output end to rotate the stirring shaft 9 in the opposite direction. The stirring shaft 9 drives the upper ratchet sleeve 13 to rotate, so that the upper ratchet sleeve 13 pushes the vertical surface of the lower ratchet sleeve 14 through its own vertical surface, causing the upper ratchet sleeve 13 to push the lower ratchet sleeve 14 to rotate. The lower ratchet sleeve 14 is driven by the limiting protrusion 15 and the limiting groove 19. The rotating connecting plate 17 drives the sealing plate 12 to move on the surface of the fixed plate 11, so that the sealing plate 12 and the fixed plate 11 are vertically aligned. This allows the mixed raw material to enter the bottom through the opening on the surface of the fixed plate 11 and contact the raw material at the bottom of the fixed plate 11, thereby replenishing the raw material entering the granulator body 24. After replenishment, the stirring shaft 9 continues to drive the sealing plate 12 to rotate through the connecting assembly, so that the sealing plate 12 seals the opening on the fixed plate 11 and adds the unmixed raw material into the mixing feed box 6. The stirring motor 8 drives the stirring shaft 9 to drive the stirring paddle 10 to rotate, thus mixing the raw material. This ensures a continuous flow of raw material into the granulator body 24, enabling continuous granulation of nylon modified granules.
