Description

Technical Field

[0001] The utility model relates to the technical field of powder coating production, in particular to an iron removal device for a feeding hopper of a thermosetting powder coating extruder. Background Art

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resins, pigments, fillers, and additives. Unlike conventional solvent-based and water-based coatings, their dispersion medium is air, not solvent and water. They are solvent-free, have 100% film-forming properties, and consume very little energy. Powder coatings are classified into two categories: thermoplastic and thermosetting. Thermoplastic powder coatings have poor film appearance (gloss and leveling) and poor adhesion to metal, resulting in their limited application in automotive finishing. Thermosetting powder coatings are generally used for automotive finishing. Thermosetting powder coatings use thermosetting synthetic resins as their film-forming material. During the drying process, the resin first melts and then solidifies through chemical crosslinking to form a smooth, hard film. The film appearance, mechanical properties, and corrosion resistance of these coatings meet the requirements of automotive finishing.

[0003] Most of the existing iron removal devices for the feed hopper of thermosetting powder coating extruders use magnets to remove iron from thermosetting powders. However, most of the existing devices are only equipped with one set of iron removal devices, which may result in insufficient iron removal efficiency for thermosetting powders, resulting in poor use of thermosetting powder coatings and inconvenience in use.

[0004] Therefore, we have made improvements to this and proposed an iron removal device for the feeding hopper of a thermosetting powder coating extruder. Utility Model Content

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0020] Example: Figures 1 to 4 As shown, the utility model is used for the iron removal device of the feeding hopper of the thermosetting powder coating extruder, comprising a base 1, a bracket 2 is fixedly connected to the four corners of the upper surface of the base 1, a movable plate 3 is slidably connected to the bracket 2, and the movable plate 3 is movably connected to the bracket 2 by bolts 9. By sliding the movable plate 3 set on the bracket 2, it is easier to adjust the height of the movable plate 3 so as to clamp and fix different cylinders; an upper removing barrel 4 and a lower removing barrel 8 are set on the base 1, and the upper removing barrel 4 is set just above the lower removing barrel 8. The upper removing barrel 4 and the lower removing barrel 8 are connected to each other, and both the upper removing barrel 4 and the lower removing barrel 8 are provided with iron removal components, which include a magnet rod 11 and a magnet disk 17. The magnet rod 11 and the magnet disk 17 are respectively arranged in the upper removing barrel 4 and the lower removing barrel 8 for circular rotation; the magnet rod 11 arranged in the upper removing barrel 4 can be used to perform preliminary iron removal operations on the thermosetting powder; at the same time, the magnet disk 17 that can rotate circularly and is arranged inside the lower removing barrel 8 can further improve the iron removal effect on the thermosetting powder.

[0021] A box cover is provided on the top of the upper removing barrel 4, and a feeding pipe 6 is provided on the box cover. The feeding pipe 6 fixedly connected to the box cover of the upper removing barrel 4 can more conveniently pass the thermosetting powder into the upper removing barrel 4 for iron removal; a motor 5 is fixedly connected to the box cover, and the output end of the motor 5 is vertically downward and fixedly connected to the mounting rod 10, and the magnet rod 11 is fixedly connected to the mounting rod 10; the motor 5 fixedly connected to the box cover can drive the mounting rod 10 to rotate, and the circularly rotating mounting rod 10 can more conveniently drive the magnet rod 11 fixedly connected to the mounting rod 10 to rotate, thereby achieving the purpose of removing iron from the thermosetting powder.

[0022] A discharge pipe 13 is fixedly connected to the bottom of the lower removal barrel 8, and the discharge pipe 13 fixedly connected to the bottom of the lower removal barrel 8 can more conveniently discharge the thermosetting powder in the lower removal barrel 8; another motor 5 is connected to the bottom of the lower removal barrel 8, and the output shaft of the motor 5 is vertically upward and fixedly connected to a rotating rod 14, and a mounting plate 16 is fixedly connected to the rotating rod 14. The motor 5 can drive the rotating rod 14 to rotate, and the rotation of the rotating rod 14 can drive the magnet disk 17 to rotate, thereby further increasing the contact area between the thermosetting powder and the magnet disk 17, and further improving the iron removal effect; the magnet disk 17 is fixedly connected to the mounting plate 16.

[0023] The mounting rod 10 is fixedly connected with a mounting block 15, and the magnet bar 11 is inserted into the mounting block 15. By fixing the mounting block 15 on the mounting rod 10, it is more convenient to install the magnet bar 11.

[0024] There are three groups of magnet disks 17 evenly distributed in the vertical direction of the rotating rod 14. The three magnet disks 17 evenly distributed in the vertical direction can perform secondary iron removal on the thermosetting powder. The magnet disks 17 are irregularly provided with through holes 12, and the diameters of the through holes 12 are different. By setting the diameters of the through holes 12 on the magnet disks 17 to be different, it is easier for the thermosetting powder to flow from the upper magnet disk 17 to the lower magnet disk 17.

[0025] The bottom of the upper removal barrel 4 is fixedly connected with a valve 7. The valve 7 fixedly connected at the bottom of the upper removal barrel 4 can make it easier to store and discharge the thermosetting powder in the upper removal barrel 4.

[0026] During operation, when it is necessary to remove iron from the thermosetting powder, the thermosetting powder to be removed by iron removal is first transported into the upper removal barrel 4 through the feeding pipe 6, and then the motor 5 is started. The motor 5 is used to drive the mounting rod 10 to rotate, thereby driving the magnet rod 11 fixedly connected to the mounting rod 10 to rotate in a circle, and the iron in the thermosetting powder is adsorbed by the circumferentially rotating magnet rod 11. After the adsorption is completed, the valve 7 fixedly connected to the upper removal barrel 4 is opened, and the thermosetting powder that has undergone the initial iron removal is transported to the lower removal barrel 8 below. Then, another motor 5 fixedly connected to the bottom of the lower removal barrel 8 is used to drive the rotating rod 14 to rotate, and the rotation of the rotating rod 14 is used to drive the magnet disk 17 to rotate in a circle, and the thermosetting powder can be subjected to secondary iron removal by utilizing the through holes 12 with different apertures provided on the magnet disk 17 and the combined action of the magnet disk 17.
