Description

Technical Field

[0001] This invention relates to the field of powder coating preparation technology, specifically to a device for adding post-mixing additives to powder coatings. Background Technology

[0002] Additives are an indispensable component in powder coating formulations. Most of these additives are added together with other raw materials during the pre-mixing stage of powder coating production. However, a few additives, such as loosening agents and lubricants, are added after the powder coating is produced, using a mixing method.

[0003] Currently, the common method for adding additives is manual, where multiple additives are typically piled directly on the surface of the raw materials. This results in uneven mixing of the additives and raw materials, requiring more time for subsequent mixing and reducing mixing effectiveness and efficiency. To address this, we propose a device for adding additives in the post-mixing process of powder coatings. Summary of the Invention

[0004] To address the shortcomings of existing methods where multiple additives are typically piled directly on the surface of raw materials, resulting in uneven mixing of the additives and raw materials, this invention provides an additive device for post-mixing additives in powder coatings. This device can mix multiple additives, achieving a premix of multiple additives, thereby improving the mixing efficiency of multiple additives and raw materials and solving the problems mentioned in the background art.

[0005] The technical solution of the present invention is implemented as follows: an additive device for powder coating post-mixing includes a crushing box, a mixing box arranged directly below the crushing box, a connecting box connecting the crushing box and the mixing box, a feeding hopper connected to the top of the crushing box, and a discharge pipe connected to the bottom of the mixing box; a second rotating shaft symmetrically arranged and rotatably connected to the crushing box, and a support cylinder rotatably connected to the second rotating shaft, and multiple through holes opened on the outer wall of the support cylinder; one end of the second rotating shaft extends to the outside of the crushing box and is connected to a first driving mechanism; a first rotating shaft symmetrically arranged and rotatably connected to the mixing box, each first rotating shaft symmetrically connected with a spiral blade, one end of the first rotating shaft extending to the outside of the crushing box and connected to the second driving mechanism.

[0006] Optionally, multiple inclined plates are symmetrically arranged on the inner top surface of the crushing box and connected thereto. The ends of the inclined plates are horizontally connected to extension plates, and multiple protrusions are fastened to the bottom of the extension plates. The protrusions abut against the outer wall of the support cylinder.

[0007] Optionally, connecting seats are symmetrically connected to the inner top surface of the crushing box. The upper end of the inclined plate is rotatably connected to the connecting seats through a rotating shaft, and a torsion spring is connected to the rotating shaft. One end of the torsion spring is connected to the inner top surface of the crushing box, and the other end of the torsion spring is connected to the inclined plate.

[0008] Optionally, the bottom of the ramp has an opening, and the other end of the torsion spring is connected inside the opening.

[0009] Optionally, the top of the crushing chamber has an installation port, which is sealed by a sealing plate. A top cover is then fastened to the top of the sealing plate, and the top cover is fastened to the top of the crushing chamber by locking bolts. The connecting seat and the sealing plate are then fastened, and one end of the torsion spring is connected to the sealing plate.

[0010] Optionally, the first drive mechanism includes a second motor and two third rotating shafts connected to the side wall of the crushing chamber. The two third rotating shafts and the two second rotating shafts are coaxially connected to second pulleys, and adjacent second pulleys are connected by a second belt. The two third rotating shafts are also coaxially connected to second gears, which mesh with each other and fix the second motor and one of the third rotating shafts.

[0011] Optionally, the second drive mechanism includes a first motor and two fourth shafts connected to the side wall of the mixing tank. Each of the two fourth shafts and the two first shafts is coaxially connected to a first pulley, and adjacent first pulleys are connected by a first belt. The two fourth shafts are also coaxially connected to a first gear, which meshes with each other and fixes the first motor and one of the fourth shafts.

[0012] Optionally, support legs are symmetrically connected to the bottom of the mixing tank along the discharge pipe.

[0013] Optionally, the bottom of the discharge pipe is fitted with a support skirt.

[0014] Optionally, a coaxial end plate is symmetrically connected to the second rotating shaft, and the support cylinder is coaxially connected between the two end plates.

[0015] Compared with the prior art, the present invention controls the support cylinder to rotate in opposite directions, so that the through holes on the support cylinder can screen large particles of additives and crush them under the crushing action of the rotating support cylinder. At the same time, the dispersion effect of multiple through holes can ensure that the additives are evenly discharged into the mixing tank. Furthermore, since each first rotating shaft is symmetrically equipped with spiral blades, multiple additives can be mixed under the drive of the spiral blades, realizing the premixing of multiple additives and effectively improving the mixing efficiency of multiple additives and raw materials.

[0023] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] Reference Figures 1 to 5 The present invention provides a technical solution: an additive device for powder coating post-mixing, including a crushing box 1, a mixing box 3 arranged directly below the crushing box 1, a connecting box 7 connecting the crushing box 1 and the mixing box 3, a feeding hopper 19 connected to the top of the crushing box 1, and a discharge pipe 6 connected to the bottom of the mixing box 3. In actual use, the device is connected to the mixing mechanism. At the same time, in order to improve the stability of the connection, a supporting skirt 5 is tightly attached to the bottom of the discharge pipe 6, and supporting legs 4 are symmetrically connected to the bottom of the mixing box 3 along the discharge pipe 6.

[0025] like Figure 1 , 3As shown in Figure 4, a second rotating shaft 16 is symmetrically arranged inside the crushing box 1 and rotatably connected to it. A support cylinder 31 is rotatably connected to the second rotating shaft 16. An end plate 24 coaxially connected to the second rotating shaft 16 is symmetrically connected to it. The support cylinder 31 is coaxially connected between the two end plates 24. Multiple through holes 32 are opened on the outer wall of the support cylinder 31. A connecting seat 28 is symmetrically connected to the inner top surface of the crushing box 1. Multiple inclined plates 21 are equidistantly arranged at the bottom of the connecting seat 28. The upper end of the inclined plate 21 is connected to the rotating shaft. 29 is rotatably connected to the connecting seat 28, and a torsion spring 26 is connected to the rotating shaft 29. One end of the torsion spring 26 is connected to the inner top surface of the crushing box 1, and the other end of the torsion spring 26 is connected to the inclined plate 21. To improve the stability of the connection of the torsion spring 26, an opening 25 is provided at the bottom of the inclined plate 21. The other end of the torsion spring 26 is connected to the opening 25. The end of the inclined plate 21 is horizontally connected to the extension plate 23, and multiple protrusions 22 are fastened at the bottom of the extension plate 23. The protrusions 22 abut against the outer wall of the support cylinder 31.

[0026] like Figure 3 , 4 As shown in Figure 5, the support cylinder 31 rotates in opposite directions, allowing the additives falling from the feed hopper 19 to scatter on the top of the support cylinder 31. Large particles of additives can be screened through the through holes 32 on the support cylinder 31 and crushed under the crushing action of the rotating support cylinder 31. At the same time, the dispersion effect of multiple through holes 32 ensures that the additives are evenly discharged into the mixing tank 3. Furthermore, since the extension plate 23 at the bottom of the inclined plate 21 abuts against the outer wall of the support cylinder 31, and the diameter of the protrusion 22 at the bottom of the extension plate 23 is smaller than the diameter of the through hole 32, when the support cylinder 31 rotates, the protrusion 22 repeatedly passes through the through hole 32, which can generate vibration on the support cylinder 31. This not only avoids clogging of the through hole 32 but also speeds up the feeding of the additives.

[0027] like Figure 1 , 3 As shown, to achieve the opposite rotation of the support cylinder 31, one end of the second rotating shaft 16 extends to the outside of the crushing box 1 and is connected to the first drive mechanism; wherein, the first drive mechanism includes a second motor 13, and two third rotating shafts 33 are connected to the side wall of the crushing box 1. The two third rotating shafts 33 and the two second rotating shafts 16 are coaxially connected to second pulleys 15, and adjacent second pulleys 15 are connected to each other by a second belt 17; the two third rotating shafts 33 are also coaxially connected to second gears 14, the two second gears 14 are meshed with each other, and the second motor 13 and one of the third rotating shafts 33 are fixedly connected.

[0028] Meanwhile, to facilitate users in inspecting and maintaining the device, such as Figure 1 , 3As shown, an installation port 2 is provided on the top of the crushing box 1. The installation port 2 is sealed by a sealing plate 27, and a top cover 18 is fastened to the top of the sealing plate 27. The top cover 18 is fastened to the top of the crushing box 1 by locking bolts 30. The connecting seat 28 and the sealing plate 27 are fastened, and one end of the torsion spring 26 is connected to the sealing plate 27.

[0029] In summary, when using the powder coating post-mixing additive, if... Figure 1 , 3 As shown, in order to achieve premixing of multiple additives before they come into contact with the raw materials, a first rotating shaft 10 is symmetrically arranged inside the mixing tank 3 and rotatably connected thereto. Each first rotating shaft 10 is symmetrically connected with a spiral blade 20. Multiple additives falling through the connecting box 7 into the mixing tank 3, since the spiral blades 20 are symmetrically arranged on each first rotating shaft 10, can drive the multiple additives to mix and transport the mixed additives to the discharge pipe 6 for rapid discharge. This allows the multiple additives to be premixed before they come into contact with the raw materials, thereby avoiding the accumulation of multiple additives on the top of the raw materials and effectively improving the mixing efficiency of additives and raw materials.

[0030] Meanwhile, one end of the first rotating shaft 10 is extended to the outside of the crushing box 1 and connected to the second drive mechanism. The second drive mechanism includes a first motor 11 and two fourth rotating shafts 34 are connected to the side wall of the mixing box 3. The two fourth rotating shafts 34 and the two first rotating shafts 10 are coaxially connected to a first pulley 9, and adjacent first pulleys 9 are connected by a first belt 8. The two fourth rotating shafts 34 are also coaxially connected to a first gear 12, and the two first gears 12 are meshed together. The first motor 11 and one of the fourth rotating shafts 34 are fixedly connected.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
