[0024] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] like Figures 1 to 5 As shown, a screening structure for metal powder discharging includes: a cover plate 6, a spring 15 and a support 7. A feed port 17 is provided in the center of the cover plate 6, mounting holes 18 are provided at both ends of the cover plate 6, and a retaining ring 8 is fixedly connected to the bottom end of the cover plate 6. A nut 5 is connected to the inner thread of the feed port 17. When metal powder is poured into the feed port 17, the nut 5 seals the feed port 17, and the cover plate 6 seals and blocks the splashing metal powder and dust.
[0026] like Figure 4 As shown, the top of the spring 15 is fixedly connected to the bottom of the cover plate 6, and the bottom of the spring 15 is fixedly connected to the limit plate 11, and the spring 15 and the retaining ring 8 do not contact each other. A sliding hole 12 is provided inside the limit plate 11, and a sliding rod 14 is slidably connected inside the sliding hole 12. The limit plate 11 slides along the sliding rod 14. At the same time, the sliding rod 14 avoids the bending of the spring 15 during operation, thereby ensuring the stability of the operation of the spring 15. At the same time, the sliding rod 14 and the limit plate 11 generate friction, so that the sliding rod 14 has a damping effect on the spring 15, thereby avoiding the resonance of the spring 15.
[0027] The top end of the support 7 is sleeved and connected in the mounting hole 18, and a threaded hole 16 is opened inside the top end of the support 7, and a bolt 4 is threadedly connected in the threaded hole 16. When the support 7 is sleeved in the mounting hole 18, the top end of the support 7 is supported inside the mounting hole 18, and the support 7 realizes the function of supporting the cover plate 6.
[0028] In some specific embodiments, a base 2 is provided at the bottom end of the pillar 7, and the pillar 7 is fixedly connected to the top of the base 2 in a direction parallel to the retaining ring 8. A vibrator 1 is provided in the center of the base 2, and the base 2 is fixedly connected around the vibrator 1 in a direction perpendicular to the pillar 7. A screen 3 is provided at the top output end of the vibrator 1, and the screen 3 is fixed to the output end of the vibrator 1 in a direction parallel to the pillar 7, and the side surface of the screen 3 away from the pillar 7 and the side surface of the retaining ring 8 close to the slide rod 14 are slidably connected. The base 2 supports the pillar 7, thereby ensuring that the pillar 7 does not vibrate up and down. When the screen 3 is running and vibrating, the retaining ring 8 preliminarily blocks and seals the dust and metal powder inside the screen 3.
[0029] In some specific embodiments, a supporting groove 9 is opened on the top of the screen 3, and a dustproof pad 10 in a circular ring shape is provided on the bottom of the supporting groove 9. The bottom end of the dustproof pad 10 is fixedly connected to the bottom of the supporting groove 9, and a limiting plate 11 is provided on the top of the dustproof pad 10. The dustproof pad 10 has a buffering effect on the limiting plate 11. At the same time, the dustproof pad 10 is squeezed and deformed by the limiting plate 11, and the deformation is filled in the supporting groove 9, thereby preventing a small amount of dust and metal powder from splashing into the air from the screen 3 through the supporting groove 9.
[0030] In some specific embodiments, the bottom end of the limiting plate 11 and the top end of the dustproof pad 10 are abutted against each other, and the limiting plate 11 is in a circular shape, and the limiting plate 11 is slidably connected to the inside of the supporting groove 9 in a direction perpendicular to the dustproof pad 10. When the screen 3 vibrates up and down, the screen 3 supports the limiting plate 11 to move up and down. The limiting plate 11 ensures that when the screen 3 vibrates, dust and metal powder will not splash from the screen 3 into the air, and the limiting plate 11 has the effect of secondary blocking and sealing.
[0031] In some specific implementation schemes, a plurality of springs 15 are provided at the bottom end of the cover plate 6. The plurality of springs 15 are equidistantly arranged along the edge direction of the cover plate 6. The springs 15 are in a compressed state. The springs 15 always support the limit plate 11, thereby ensuring that the bottom end of the limit plate 11 always supports the dustproof pad 10. The arrangement of the springs 15 ensures that the limit plate 11 is subjected to uniform force in the vertical direction.
[0032] In some specific embodiments, the threaded hole 16 passes through the inside of the side end of the cover plate 6, and the height dimension of the threaded hole 16 is equal to the thickness dimension of the cover plate 6. The threaded hole 16 ensures that the bolt 4 can completely connect the cover plate 6 and the pillar 7, avoiding the cover plate 6 from falling off the pillar 7, thereby ensuring the stability of the cover plate 6.
[0033] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:
[0034] Pour the metal powder onto the screen 3 from the feed port 17 on the cover plate 6, thread the nut 5 into the feed port 17, turn on the vibrator 1, and the vibrator 1 drives the screen 3 to vibrate up and down, and the screen 3 separates the metal powder. At the same time, the screen 3 holds the limit plate 11 to move up and down. When the metal powder splashes, the retaining ring 8 blocks the metal powder for the first time, and the limit plate 11 blocks the metal powder for the second time. The cover plate 6 achieves the effect of sealing the screen 3 to prevent the metal powder and dust from splashing into the air, thereby improving the use effect of the screening machine. The retaining ring 8 achieves the effect of initially blocking and sealing the splashing metal powder, and the limit plate 11 achieves the effect of secondary blocking and sealing the splashing metal powder and dust, thereby ensuring that the cover plate 6 fully blocks and seals the splashing metal powder and dust.
[0035] When the limit plate 11 moves up and down, the limit plate 11 slides along the slide bar 14, and the spring 15 always gives the limit plate 11 a downward force to support the dust pad 10. The dust pad 10 is filled with force in the supporting groove 9. The slide bar 14 ensures the stability of the limit plate 11 in the up and down vibration, and avoids the limit plate 11 from tilting, thereby ensuring the stability of the structure. The spring 15 ensures that the limit plate 11 always supports the dust pad 10, and the dust pad 10 strengthens the blocking and sealing effect of the limit plate 11. When the cover plate 6 is installed, the mounting hole 18 on the cover plate 6 is set on the pillar 7, and the bolt 4 is threaded in the threaded hole 16. The pillar 7 supports the cover plate 6, and the bolt 4 connects and fixes the cover plate 6 and the pillar 7.
[0036] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
