Description
Technical Field
[0001] The utility model relates to the technical field of nylon particle mixers, in particular to a nylon pelletizing device. Background Art
[0002] As a high-performance engineering plastic, nylon may have low melt strength under certain conditions, resulting in the inability to properly strand pelletize. In order to obtain granular products suitable for subsequent processing and application, the nylon melt needs to be cut into pellets using a pelletizing device.
[0003] Current nylon pelletizing devices clearly have significant shortcomings in terms of efficiency and convenience. While the pelletizing process can be largely completed, it is often followed by a tedious process of collecting the pellets. These pellets are scattered and disorderly, increasing the labor intensity of manual collection and easily leading to mixing and contamination between the pellets. Even more inconveniently, these pellets then need to be transferred to a screening device to further remove unqualified products. This series of operations is not only time-consuming and labor-intensive, but also seriously affects the smoothness and efficiency of the entire production line, making the production process of nylon pellets particularly cumbersome and inefficient. Therefore, we propose a nylon pelletizing device. Utility Model Content
[0004] The present utility model aims to provide a nylon pelletizing device to address the aforementioned background art issue, namely that existing pelletizers often require a cumbersome pellet collection process after pelletizing nylon. These pellets are scattered and disorderly, increasing the labor intensity of manual collection and easily leading to inter-particle mixing and contamination. Furthermore, these pellets then need to be transferred to a screening device to further remove unqualified products. This series of operations is not only time-consuming and labor-intensive, but also seriously affects the fluidity and efficiency of the entire production line, making the production process of nylon pellets particularly cumbersome and inefficient.
[0005] Base comprises support, castor, and frame upper is provided with guide rail, and support and conveyer frames movable end contact site are provided with recoil spring or rubber cushion, and castor is arranged on the pin of base bottom four, to carry mobile handler location.
[0006] Compared with the prior art, the beneficial effects of the present invention are:
[0007] The nylon pelletizing device uses a vertical plate, a cam, a spring, a screen box, a moving wheel and a third motor. After the nylon pelletizing device completes the pelletizing operation, the nylon particles will fall into the top screen box. At this time, by controlling the start of the third motor, the cam can be driven to rotate stably. The rotational motion of the cam is converted into left and right shaking of the screen box through its contact with the right vertical plate. This dynamic screening process effectively promotes the separation between particles and the removal of impurities. At the same time, the elastic connection of the spring not only provides the necessary reset force for the screen box, but also enhances the stability and durability during the screening process. More importantly, the setting of the moving wheel realizes sliding support for the screen box, ensuring that the screen box can move smoothly left and right during the screening process, reducing the friction resistance and noise generated during screening, and further improving the screening efficiency and accuracy. This instant screening design avoids the tedious steps of manually transferring particles to the screening device in the traditional method, which not only saves time and labor costs, but also significantly improves the overall fluency and automation level of the production line.

[0020] A sliding plate is fixedly connected to the top of one side of the feed platform 2 to guide the nylon particles after pelletizing. The sliding plate is arranged in an inclined structure so that the particles can accurately slide into the screen box 20 above. The front surfaces of the three screen boxes 20 and the front surface of the processing chamber 1 are movably installed with movable doors, and the screened particles can be collected and taken out by opening the movable doors.
[0021] A connecting frame 14 is provided at the upper end of the pelletizer 15, and a second motor 16 is fixedly installed on the front surface of the connecting frame 14. The second motor 16 is fixedly connected to the second main shaft through the output end of the rear surface of the second motor 16. The rear end of the second main shaft passes through the outside of the connecting frame 14 and is fixedly connected to the center of the front surface of the pelletizer 15. A second electric push rod 13 is fixedly installed at the center of the top of the processing chamber 1. The lower end of the second electric push rod 13 passes through the interior of the processing chamber 1 and is fixedly connected to the top of the connecting frame 14. By controlling the second motor 16, the pelletizer 15 can be driven to rotate, thereby realizing the pelletizing operation of the nylon strips.
[0022] There are three screen boxes 20, and the three screen boxes 20 are arranged vertically, so that nylon particles of different particle sizes can fall into different screen boxes 20 respectively, realizing the graded screening of the particles. There are four springs 19, and one end of the four springs 19 is fixedly connected to the four corners of one side of the left vertical plate 17, and the other ends of the four springs 19 are fixedly connected to the inner wall of the processing chamber 1. One side of the cam 18 is in contact with the outer wall of the right vertical plate 17. The third motor 22 is fixedly connected to the third main shaft through the output end of its rear surface. The rear end of the third main shaft passes through the interior of the processing chamber 1 and is fixedly connected to the front surface of the cam 18. The bottoms of the four moving wheels 21 are in contact with the inner bottom of the processing chamber 1.
[0023] Working Principle: First, nylon strips are placed in several equally spaced feed troughs 3 atop the feed platform 2. Next, the first motor 12 is activated, driving the first spindle, which in turn rotates the connected right friction roller 5. Because the three drive pulleys 10 are connected via a belt 11, the rotation of the first motor 12 is simultaneously transmitted to the remaining two friction rollers 5, achieving synchronized rotation. Next, the first electric push rod 6 adjusts the height of the lifting bracket 4, ensuring that the friction rollers 5 are in close contact with and compress the nylon strips. Through friction, the friction rollers 5 convey the nylon strips along the feed trough 3 into the processing chamber 1. Once in the processing chamber 1, the friction rollers 5 continue to push the nylon strips forward until they reach the pelletizing area. At this point, the second motor 16 is activated, driving the second spindle, which in turn drives the pelletizer 15 at high speed. Simultaneously, the second electric push rod 13 adjusts the position of the pelletizer 15 as needed, ensuring it maintains an appropriate cutting distance from the nylon strips. The rotating pelletizer 15 cuts the nylon strips into pellets. The nylon particles after pelletizing slide down to the screen box 20 below through the sliding plate on one side of the feed platform 2. There are three screen boxes 20 arranged vertically, and each screen box 20 has a different mesh size to achieve graded screening of particles of different particle sizes. At the same time, the third motor 22 is started, which drives the third main shaft to rotate, thereby driving the cam 18 to rotate. Since the cam 18 contacts the outer wall of the right vertical plate 17, and the vertical plate 17 is connected to the inner wall of the processing chamber 1 through the spring 19, the rotation of the cam 18 will cause the screen box 20 to shake in the horizontal direction, accelerating the particle screening process. The setting of the moving wheel 21 ensures the stability of the screen box 20 during the shaking process, reducing direct contact and wear with the bottom of the processing chamber 1. Finally, the nylon particles after screening fall into different screen boxes 20 respectively. The user can collect and remove the particles by opening the movable door on the front surface of the screen box 20, completing the entire pelletizing and screening process.
[0024] In summary, the nylon pelletizing device, through the coordinated use of the vertical plate 17, the cam 18, the spring 19, the screen box 20, the moving wheel 21 and the third motor 22, after the nylon pelletizing device completes the pelletizing operation, the nylon particles will fall into the top screen box 20. At this time, by controlling the start of the third motor 22, the cam 18 can be driven to rotate stably. The rotational movement of the cam 18 is converted into the left and right shaking of the screen box 20 through its contact with the right vertical plate 17. This dynamic screening process effectively promotes the separation between particles and the removal of impurities. At the same time, the elastic connection of the spring 19 does not It not only provides the necessary reset force for the screen box 20, but also enhances the stability and durability during the screening process. More importantly, the setting of the moving wheel 21 realizes the sliding support of the screen box 20, ensuring that the screen box 20 can move smoothly left and right during the screening process, reducing the friction resistance and noise generated during screening, and further improving the screening efficiency and accuracy. This instant screening design avoids the tedious steps of manually transferring particles to the screening device in the traditional method, which not only saves time and labor costs, but also significantly improves the overall fluency and automation level of the production line.
