Description

Technical Field

[0001] This utility model relates to the field of powder screening equipment technology, and in particular to a powder screening equipment for low melting point water-resistant copolyamide hot melt adhesive. Background Technology

[0002] Polyamide hot melt adhesive is a polymer material made by copolymerization of diacid and diamine. It is then processed through modification and pulverization. Its preparation is based on the high-temperature condensation of diacid and polyamine. It is divided into two categories: high molecular weight and low molecular weight. It is widely used in bonding fabrics, leather, metals, and ceramics, as well as in the protection of electronic components and bookbinding. Generally, when sieving fine polyamide hot melt adhesive powder, machine vibration is usually used to sieve it, which can remove the adhesive particles and obtain powder. However, the adhesive particles are easy to clog the sieve holes, which requires manual cleaning to prevent clogging, affecting subsequent sieving, which is time-consuming and labor-intensive, thus reducing the effectiveness of use. Utility Model Content

[0022] Reference Figure 1-5 This utility model provides a sieving device for low-melting-point, washable copolyamide hot melt adhesive, comprising a receiving bracket 1, a receiving shell 2 above the receiving bracket 1, a receiving baffle 3 fixedly connected to the top of the receiving shell 2, a receiving feed hopper 4 fixedly connected to the top of the receiving baffle 3, two spring dampers 5 fixedly connected to both sides of the outer wall of the receiving shell 2, the ends of the spring dampers 5 fixedly connected to the receiving bracket 1, a receiving discharge channel 7 fixedly connected to one end of the receiving shell 2, a discharge channel fixedly connected to the bottom of the receiving shell 2, a discharge valve connected to the side wall of the discharge channel, a vibration motor 6 installed on the side wall of the receiving shell 2, a fixed frame 8 fixedly connected between the two sides of the inner wall of the receiving shell 2, multiple fixed screens 9 fixedly connected between the two sides of the inner wall of the fixed frame 8, and a fixed suspension bracket 10 fixedly connected to the bottom of the fixed frame 8. The bottom of the suspension bracket 10 has two fixing slots. Two fixing blocks 11 are movably sleeved on the outer wall of the fixed suspension bracket 10. A fixing recess 12 is fixedly connected between the tops of the two fixing blocks 11. A movable component is connected to the bottom of the fixing blocks 11. The movable component is used to adjust the fixing recess 12 to a suitable distance. The movable component includes a movable outer shell 23 fixedly connected to the bottom of the fixing blocks 11. A movable motor 24 is fixedly connected between the two sides of the inner wall of the movable outer shell 23. A movable rod 25 is fixedly connected to the output end of the movable motor 24. The end of the movable rod 25 passes through the movable outer shell 23 and the fixing blocks 11 and extends into the corresponding fixing slot. A movable wheel 26 is fixedly connected to the end of the movable rod 25. The movable motor 24 is used to drive the movable wheel 26 on the movable rod 25 to rotate.

[0023] Both sides of the outer wall of the fixed recess 12 are provided with moving grooves. A moving slider 13 is slidably connected inside the moving groove. One end of the moving slider 13 is fixedly connected to the moving recess 16. A moving ring plate 17 is fixedly connected between the two sides of the inner wall of the moving recess 16. Both sides of the outer wall of the fixed recess 12 are connected to connecting components. The connecting components include a connecting bracket 18 fixedly connected to the outer wall of the fixed recess 12. A connecting housing 19 is fixedly connected to the side wall of the connecting bracket 18. A connecting motor 20 is fixedly connected between the two sides of the inner wall of the connecting housing 19. The output shaft of the connecting motor 20 passes through the connecting housing 19 and the connecting bracket 18 and is fixedly connected to a connecting plate 21. A connecting shaft 22 is rotatably connected to the side wall of the connecting plate 21. The connecting shaft 22 is slidably connected to the corresponding moving ring plate 17 inside. The connecting components achieve the purpose of adjusting the movement of the moving ring plate 17.

[0024] A movable component is provided between the other ends of the two movable sliders 13.

Multiple movable anti-blocking inserts 15 are fixedly connected to the top of the movable anti-blocking plate 14. The movable component serves to prevent the fixed screen 9 from blocking.

[0025] Working principle: When in use, the material to be screened is first poured into the receiving hopper 4, then falls through the receiving shell 2 onto the fixed screen 9 on the fixed frame 8. Since the receiving shell 2 is installed with the receiving bracket 1 through the spring damper 5, the vibration motor 6 is then started. The vibration motor 6 drives the receiving shell 2 to vibrate, which causes the fixed frame 8 on the receiving shell 2 to also drive the fixed screen 9 to vibrate and screen. Then the screened material falls into the discharge channel. Then the discharge valve on the discharge channel is started to discharge the screened material. Then the material that is not completely screened on the fixed screen 9 is discharged through the receiving discharge channel 7.

[0026] Then, as needed, the movable motor 24 on the movable housing 23 is activated, which drives the movable rod 25 and the movable wheel 26 to rotate. The movable wheel 26 then moves along the inside of the fixed groove. The movable motor 24 also drives the fixed sleeve block 11 to move along the direction on the fixed suspension bracket 10. The fixed sleeve block 11 also drives the movable component on the fixed recess 12 and the movable anti-blocking insert 15 on the movable anti-blocking plate 14 to adjust to a suitable distance.

[0027] Next, the connecting motor 20 on the connecting housing 19 is started. The connecting motor 20 drives the connecting plate 21 and the connecting shaft 22 to rotate, so that the connecting shaft 22 slides inside the corresponding movable eccentric plate 17. Then, the movable eccentric plate 17 also drives the movable slider 13 on the movable recess 16 to slide inside the movable groove. Then, the movable slider 13 also drives the movable anti-blocking plate 14 and the movable anti-blocking insert 15 to contact the fixed screen 9 in one of the areas, so that the movable anti-blocking insert 15 repeatedly agitates the screen holes on the fixed screen 9 to reduce material blockage.
