Description

Technical Field

[0001] This utility model is a glass fiber raw material crushing device, belonging to the field of glass fiber raw material crushing technology. Background Technology

[0002] Glass fiber, also known as glass fiber, is a commonly used polymer material in modern times. In the production process of glass fiber, various raw materials such as quartz sand and limestone are crushed, melted, and finally drawn into fibers. In the modern glass fiber production process, recycled glass fiber resin and other raw materials are crushed and reused, which is not only more environmentally friendly, but also can effectively shorten the glass fiber manufacturing process.

[0003] Some raw materials that are not completely crushed will remain in the crushed material, which will cause the melting speed of these raw materials to be slow during the subsequent melting process. If the subsequent wire drawing work is carried out before the materials are melted, defective products are likely to be produced. Screening the crushed material requires additional equipment and takes a lot of time. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a glass fiber raw material crushing device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A glass fiber raw material crushing device includes a crushing box, a feeding hopper at the top of the crushing box, a frame at the bottom of the crushing box, a discharge port extending into the frame at the bottom end of the crushing box, and a screening mechanism for screening the crushed raw material inside the frame and below the discharge port. The frame has a hollow structure, and each of the bottom corners of the frame is equipped with a self-locking caster wheel. The bottom of the frame is also equipped with a stabilizing mechanism to increase operational stability. The stabilizing mechanism includes a counterweight, and a hydraulic cylinder connected to the frame is located on the top of the counterweight.

[0006] Furthermore, the screening mechanism includes a horizontally arranged fixed frame, and symmetrically arranged side frames on both sides of the bottom of the fixed frame. The bottom of the side frames is connected to the frame, and a screen plate one and a screen plate two are inclinedly arranged between the two sets of frames from top to bottom.

[0007] Furthermore, the sieve holes on the first sieve plate are larger than those on the second sieve plate, and the first sieve plate is provided with a symmetrically arranged fixed shaft one and a fixed shaft two on both sides, and the two sets of fixed shaft one are provided with an L-shaped movable shaft one that is movably connected to the fixed frame.

[0008] Furthermore, each side of the sieve plate two is provided with a symmetrically arranged fixed shaft three and a fixed shaft four, and the two sets of fixed shaft three are provided with L-shaped movable shaft two that are movably connected to the side frame.

[0009] Furthermore, a side plate is provided inside the side frame and on one side of the fixed shaft two and the fixed shaft four, and a through hole is provided on the side plate for the movement of the fixed shaft two and the fixed shaft four.

[0010] Furthermore, an inclined movable block is provided on one side of the side plate and between the second fixed shaft and the fourth fixed shaft. The two ends of the movable block are movably connected to the second fixed shaft and the fourth fixed shaft, respectively, and the middle part of the movable block is provided with a fixed shaft that is movably connected to the side plate.

[0011] Furthermore, an inclined movable rod is movably connected to the end of the fixed shaft two, and a movable ring is provided at the bottom end of the movable rod. A turntable is rotatably connected inside the movable ring, and an eccentrically connected drive shaft is provided on the turntable.

[0012] Furthermore, the frame is equipped with a motor for driving the drive shaft to rotate, and an electrical control box is located on the top of the frame, with an alarm light on the top of the electrical control box.

[0013] The beneficial effects of this utility model are: With the setting of the crushing box, two crushing rollers rotate to crush the raw materials fed from above the crushing box, and the crushed raw materials fall onto the screening mechanism for screening. With the setting of the screening mechanism, the screen plate one and screen plate two are pushed and pulled back and forth by the moving rod. The shaking of screen plate one and screen plate two can improve the screening efficiency. It can directly screen the material after crushing, prevent the incompletely crushed material from entering the subsequent process, and ensure the quality of the finished product. Because the sieve holes on sieve plate one are larger than those on sieve plate two, the incompletely crushed material remaining in sieve plate one is discharged from the bottom, undergoes secondary screening on sieve plate two, and is then collected uniformly.

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution for a glass fiber raw material crushing device, including a crushing box 1, a feeding hopper 2 at the top of the crushing box 1, a frame 3 at the bottom of the crushing box 1, a discharge port 4 extending into the frame 3 at the bottom end of the crushing box 1, and a screening mechanism for screening the crushed raw material inside the frame 3 and below the discharge port 4. The frame 3 has a hollow structure, and each of the bottom corners of the frame 3 is equipped with a self-locking universal wheel, and the bottom of the frame 3 is equipped with a stabilizing mechanism to increase operational stability. The stabilizing mechanism includes a counterweight 5, and a hydraulic cylinder 6 connected to the frame 3 is provided on the top of the counterweight 5.

[0019] Please see Figure 1-4The screening mechanism includes a horizontally arranged fixed frame 7, and symmetrically arranged side frames 8 on both sides of the bottom of the fixed frame 7. The bottom of the side frames 8 is connected to the frame 3. Between the two sets of frames 3, a first screen plate 9 and a second screen plate 10 are inclinedly arranged from top to bottom. The screen holes on the first screen plate 9 are larger than the screen holes on the second screen plate 10. The first screen plate 9 has a first fixed shaft 11 and a second fixed shaft 12 symmetrically arranged on both sides. The first fixed shaft 11 has an L-shaped movable shaft 13 movably connected to the fixed frame 7. The second screen plate 10 has a third fixed shaft 22 and a fourth fixed shaft 23 symmetrically arranged on both sides. The third fixed shaft 22 has an L-shaped movable shaft 14 movably connected to the side frame 8.

[0020] Please see Figure 1-4 A side plate 24 is provided inside the side frame 8 and on one side of the fixed shaft 22 and the fixed shaft 4 23. The side plate 24 has through holes 15 for the movement of the fixed shaft 22 and the fixed shaft 4 23. An inclined movable block 16 is provided on one side of the side plate 24 and between the fixed shaft 22 and the fixed shaft 4 23. The two ends of the movable block 16 are respectively movably connected to the fixed shaft 22 and the fixed shaft 4 23. A fixed shaft is provided in the middle of the movable block 16 and is movably connected to the side plate 24. An inclined movable rod 17 is movably connected to the end of the fixed shaft 22. A movable ring 18 is provided at the bottom of the movable rod 17. A turntable 19 is rotatably connected inside the movable ring 18. An eccentrically connected drive shaft 20 is provided on the turntable 19. A motor 21 for driving the drive shaft 20 to rotate is provided inside the frame 3.

[0021] During use, two crushing rollers rotate to crush the raw materials fed into the crushing box 1 from above. The crushed raw materials fall onto the screen plate 9 for sieving. During this process, the motor 21 drives the turntable 19 to rotate eccentrically within the movable ring 18 via the drive shaft 20. The movable ring 18 moves up and down with the eccentricity of the turntable 19. The turntable 19 drives the fixed shaft 12 to reciprocate within the through hole 15 via the movable rod 17. During the movement, the fixed shaft 12 drives the movable block 16 to reciprocate around the fixed shaft as the axis, thereby driving the fixed shaft 23 to reciprocate within the through hole 15. This causes the fixed shaft 22 and the fixed shaft 23 to vibrate the screen plate 9 and the screen plate 10 respectively in coordination with the fixed shaft 11 and the fixed shaft 22, improving the sieving efficiency. Since the sieve holes on the screen plate 9 are larger than those on the screen plate 20, the incompletely crushed material remaining in the screen plate 9 is discharged from the bottom, sieved a second time by the screen plate 20, and then collected uniformly.
