Description

Technical Field

[0001] This utility model is an antistatic powder coating dispersion and discharge device, belonging to the field of antistatic powder coating packaging. Background Art

[0002] Antistatic powder coatings are primarily composed of epoxy and polyester resins, as well as highly conductive fillers and metal powders. They are primarily used for antistatic and static elimination in environments such as hospital operating rooms and computer rooms. By installing multiple discharge pipes at the bottom of an antistatic powder coating silo, the antistatic powder coating in the silo can be simultaneously discharged through the multiple discharge pipes into packaging containers, which helps improve packaging efficiency. However, because the multiple discharge pipes are spaced at varying distances from the center of the silo bottom, the amount of antistatic powder coating discharged from each discharge pipe per unit time varies, hindering the ability to uniformly replace packaging containers. Therefore, a dispersed discharge device is needed to ensure that the multiple discharge pipes discharge the same amount of antistatic powder coating per unit time. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an antistatic powder coating dispersion and discharge device to solve the problems raised in the above background technology. The utility model makes it possible to make the amount of antistatic powder coating discharged by multiple discharge pipes per unit time be the same.

[0004] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an anti-static powder coating dispersion and discharging device, including a gathering silo, a bottom silo is installed at the bottom of the gathering silo, the cross-section of the bottom silo is trapezoidal, and a plurality of vertically arranged discharge pipes are evenly installed at the bottom of the bottom silo, a conical head is inserted in the discharge pipe, the diameter of the conical head gradually decreases from bottom to top, a U-shaped rod is connected and fixed to the bottom of the conical head, a vertical part of the U-shaped rod passes through a vertical hole, the vertical hole is provided on the upper surface of the support, the support is fixed to the outer surface of the lower end of the discharge pipe, a threaded hole is provided on the side of the support facing away from the discharge pipe, and a bolt for limiting the relative position of the U-shaped rod and the support is threadedly connected in the threaded hole.

[0005] Furthermore, a cylinder is connected and fixed to the lower end of the discharge pipe, the lower end of the cylinder is open, the discharge pipe is communicated with the cylinder, and a through-hole aligned with the vertical hole is opened on the upper surface of the cylinder. A vertical part of the U-shaped rod passes through the through-hole, and the diameter of the U-shaped rod is the same as the inner diameter of the through-hole.

[0006] Furthermore, a straight cylinder is provided on the outside of the threaded hole and is arranged concentrically with the threaded hole. One end of the straight cylinder is connected and fixed to the support. The bolt passes through the straight cylinder. A shielding ring is slidably installed in the straight cylinder. The shielding ring is sleeved on the bolt and fixed to the bolt.

[0007] Furthermore, a knob head is fixed to one end of the bolt on the outside of the straight cylinder, and the outer surface of the knob head is machined with multiple anti-slip grooves at equal intervals in a ring shape.

[0008] Furthermore, the side of the support facing the discharge pipe is machined with an arc-shaped surface, and the curvature of the arc-shaped surface is the same as that of the discharge pipe.

[0009] Furthermore, a plurality of circular openings are evenly opened at the bottom of the bottom bin, and the upper end of the discharge pipe is installed in the circular opening.

[0010] Furthermore, a connecting plate is fixedly connected to the upper part of each of the two parallel sides of the material hopper, and two fixing holes for inserting screws are opened on the upper surface of the connecting plate.

[0011] Furthermore, a reinforcing rib is fixedly connected to the lower surface of the connecting plate, and the reinforcing rib is fixedly connected to the material hopper.

[0012] The beneficial effects of this utility model are:

[0013] 1. Adjust the relative position of the U-shaped rod and the support along the vertical hole. At this time, the length of the conical head inserted in the discharge pipe changes. Since the diameter of the conical head gradually decreases from bottom to top, the longer the length of the conical head inserted in the discharge pipe, the smaller the discharge channel formed by the discharge pipe and the conical head. This increases the length of the conical head inserted in the discharge pipe near the bottom center area of ​​the silo, and decreases the length of the conical head inserted in the discharge pipe far from the bottom center area of ​​the silo. This ensures that the amount of antistatic powder coating discharged from multiple discharge pipes per unit time is the same, which facilitates the simultaneous filling of packaging containers on the lower side of multiple discharge pipes and makes it easier to replace packaging containers uniformly. Tighten the bolts to make the bolts fit tightly with the U-shaped rod, thereby fixing the position of the U-shaped rod.

[0014] 2. Install a cylinder at the lower end of the discharge pipe. Under the obstruction of the cylinder, the amount of antistatic powder coating discharged from the channel formed by the conical head and the discharge pipe is blocked by the cylinder, thereby limiting the diffusion range of the antistatic powder coating and facilitating the smooth falling of the antistatic powder coating into the packaging container.

[0015] 3. The retaining ring installed on the bolt is slidably installed inside the cylinder. At this time, the threaded connection between the bolt and the threaded hole is in the space formed by the retaining ring and the cylinder, preventing small debris from entering the threaded hole at will.

Detailed Implementation

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Please see Figure 1 This utility model provides a technical solution: an antistatic powder coating dispersion and discharge device, including a material silo 1, a bottom silo 2 installed at the bottom of the material silo 1, the bottom silo 2 having a trapezoidal cross-section, and connecting plates 4 fixedly connected to the upper parts of the two parallel sides of the material silo 1. The upper surface of the connecting plates 4 has two fixing holes 3 for inserting screws, and the lower surface of the connecting plates 4 is fixedly connected to a reinforcing rib. The reinforcing rib is fixedly connected to the material silo 1, and the reinforcing rib improves the mechanical strength of the connection between the connecting plates 4 and the material silo 1. The connecting plates 4 are installed at the bottom of the silo using screws, thus completing the assembly of the structure formed by the material silo 1 and the bottom silo 2 with the silo.

[0027] See Figures 1-7, a plurality of vertically arranged discharge pipes 5 are evenly installed at the bottom of the bottom bin 2, wherein a plurality of circular openings 17 are evenly opened at the bottom of the bottom bin 2, the upper end of the discharge pipe 5 is installed in the circular opening 17, and a conical head 12 is inserted in the discharge pipe 5, and the diameter of the conical head 12 gradually decreases from bottom to top, and a U-shaped rod 8 is connected and fixed to the bottom of the conical head 12, and a vertical portion of the U-shaped rod 8 passes through a vertical hole 13, and the vertical hole 13 is opened on the upper surface of the support 7, and the support 7 is fixed to the outer surface of the lower end of the discharge pipe 5. The side of the support 7 facing the discharge pipe 5 is processed with an arc surface, and the curvature of the arc surface is the same as the curvature of the discharge pipe 5. The design of the arc surface increases the connection range between the support 7 and the discharge pipe 5, and a threaded hole 15 is opened on the side of the support 7 away from the discharge pipe 5. The threaded hole 15 is threadedly connected with a bolt 10 for limiting the relative position of the U-shaped rod 8 and the support 7, along the vertical hole 13 Adjust the relative position of the U-shaped rod 8 and the support 7. At this time, the length of the conical head 12 inserted in the discharge pipe 5 changes. Since the diameter of the conical head 12 gradually decreases from bottom to top, the longer the conical head 12 is inserted in the discharge pipe 5, the smaller the discharge channel formed by the discharge pipe 5 and the conical head 12. The length of the conical head 12 inserted in the discharge pipe 5 near the center area of ​​the bottom of the silo is increased, and the length of the conical head 12 inserted in the discharge pipe 5 away from the center area of ​​the bottom of the silo is reduced, so that the amount of antistatic powder coating discharged from multiple discharge pipes 5 per unit time is the same, which is convenient for filling the packaging containers on the lower sides of multiple discharge pipes 5 at the same time, which is conducive to unified replacement of packaging containers. Tighten the bolt 10 to make the bolt 10 fit tightly against the U-shaped rod 8 to fix the position of the U-shaped rod 8.

[0028] See Figure 1 , Figure 3 and Figure 4 The lower end of the discharge pipe 5 is connected and fixed with a cylinder 6, the lower end of the cylinder 6 is open, the discharge pipe 5 is communicated with the cylinder 6, and a through-hole 14 is provided on the upper surface of the cylinder 6, which is aligned with the vertical hole 13. A vertical portion of the U-shaped rod 8 passes through the through-hole 14, and the diameter of the U-shaped rod 8 is the same as the inner diameter of the through-hole 14. The cylinder 6 is installed at the lower end of the discharge pipe 5. Under the cover of the cylinder 6, the amount of antistatic powder coating discharged from the channel formed by the conical head 12 and the discharge pipe 5 is blocked by the cylinder 6, thereby limiting the diffusion range of the antistatic powder coating, which is conducive to the smooth fall of the antistatic powder coating into the packaging container. A baffle is installed at the movable end of the cylinder. When the packaging container needs to be replaced, the cylinder is controlled to extend so that the baffle moves to the lower side of the cylinder 6 and fits with the lower end of the cylinder 6 to achieve sealing of the lower end of the cylinder 6.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6A straight cylinder 9 is provided on the outside of the threaded hole 15 and is concentrically arranged with the threaded hole 15. One end of the straight cylinder 9 is connected and fixed to the support 7. The bolt 10 passes through the straight cylinder 9. A shielding ring 16 is slidably installed in the straight cylinder 9. The shielding ring 16 is sleeved on the bolt 10 and fixed to the bolt 10. The end of the bolt 10 on the outside of the straight cylinder 9 is connected and fixed with a knob head 11. The outer surface of the knob head 11 is annular and equidistantly processed with multiple anti-slip grooves, so that the shielding ring 16 installed on the bolt 10 is slidably installed in the cylinder 6. At this time, the threaded connection part of the bolt 10 and the threaded hole 15 is in the space formed by the shielding ring 16 and the cylinder 6, preventing small debris from entering the threaded hole 15 at will.
