Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to a powder coating mixing device. 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 or water. They are solvent-free, have 100% film formation, and consume very little energy. The main characteristics of powder coatings include being harmless, highly efficient, resource-efficient, and environmentally friendly. Raw material mixing is a key step in powder coating production. Existing mixing devices typically use a coaxial shaft with a mixing drum, which rotates with a stirring blade to mix the coating within the drum. However, these mixing devices have the following drawbacks: Because the shaft of the stirring blades is coaxial with the drum, the shaft-driven stirring blades mix the materials in the middle of the drum more evenly and thoroughly, but the coating on the outer edges of the drum is not thoroughly mixed. Utility Model Content

[0003] In view of the above situation, in order to make up for the deficiencies of the prior art, the purpose of the present invention is to provide a powder coating mixing device, which effectively solves the problem of poor mixing effect of the prior powder coating mixing device.

[0004] The technical solution is that the utility model includes an upper and lower axial mixing barrel, a rotatable shaft is coaxially provided in the mixing barrel, a connecting plate is provided at the lower end of the shaft in the left and right directions, the free end of the connecting plate is rotatably connected to a rotating column in the upper and lower axial directions, a plurality of stirring blades are provided on the rotating column, a transmission gear located above the connecting plate is coaxially provided on the rotating column, and a ring gear meshing with the transmission gear is coaxially provided on the upper side wall of the mixing barrel.

[0005] Compared with the existing technology, the beneficial effect of the present invention is that it can fully stir the materials in various areas of the mixing barrel, make the materials fully mixed, and achieve the best mixing effect. Compared with the traditional mixing device, it can fully mix the materials inside and outside the mixing barrel. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the basic embodiments disclosed below.

[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0014] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 It is given, including a mixing barrel 1 with upper and lower axial directions, a rotatable shaft 2 is coaxially provided in the mixing barrel 1, a connecting plate 3 in the left and right directions is provided at the lower end of the rotating shaft 2, and the free end of the connecting plate 3 is rotatably connected to a rotating column 4 with upper and lower axial directions, a plurality of stirring blades 5 are provided on the rotating column 4, a transmission gear 6 located above the connecting plate 3 is coaxially provided on the rotating column 4, and a ring gear 7 meshing with the transmission gear 6 is coaxially provided on the upper side wall of the mixing barrel 1.

[0016] In order to rotate the rotating shaft 2, a motor 8 is coaxially provided on the upper end of the mixing drum 1. The output shaft of the motor 8 is coaxially fixedly connected to the rotating shaft 2, and the rotating shaft 2 is rotatably connected to the mixing drum 1.

[0017] In order to facilitate the collection of materials, a funnel-shaped sliding plate 9 is provided on the lower inner side of the mixing barrel 1 and is located below the rotating column 4.

[0018] In order to facilitate the addition and unloading of materials, a feeding hole is provided at the upper end of the mixing barrel 1 , a dust plug 10 is detachably connected to the feeding hole, and a discharge pump 11 is provided at the lower end of the mixing barrel 1 .

[0019] In order to facilitate supporting the mixing drum 1 , a plurality of supporting legs 12 evenly distributed along the circumference of the mixing drum 1 are provided at the lower end of the mixing drum 1 .

[0020] In order to facilitate sampling, a sampling tube 13 is provided on the right side of the mixing cylinder 1.

[0021] When the present invention is in use, the dust plug 10 is first opened, and the coating powder to be mixed is added into the mixing barrel 1 through the feeding hole, and then the dust plug 10 is covered again. At this time, the motor 8 is turned on, and the motor 8 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the rotating column 4 to rotate around the rotating shaft 2 through the connecting plate 3, and at the same time drives the rotating column 4 to drive the transmission gear 6 to rotate around the rotating shaft 2. At this time, since the ring gear 7 is fixed and meshes with the transmission gear 6, the transmission gear 6 is driven to rotate when the rotating column 4 rotates around the rotating shaft 2, and the transmission gear 6 drives the rotating column 4 to rotate. The rotating column 4 drives the multiple stirring blades 5 thereon to rotate to achieve stirring of the materials in the mixing barrel 1;

[0022] While the rotating column 4 drives the stirring blade 5 to achieve stirring, the rotating stirring blade 5 also rotates around the rotating shaft 2 in the mixing barrel 1, fully and thoroughly stirring and mixing the materials in various areas of the mixing barrel 1 to achieve the best mixing effect. When it is necessary to evaluate and inspect the mixed materials, a certain amount of material in the mixing barrel 1 is taken out from the sampling tube 13 for evaluation and inspection. When the material mixing is completed, the discharge pump 11 is turned on, and the discharge pump 11 can discharge the mixed material in the mixing barrel 1.

[0023] Compared with the existing technology, the beneficial effects of the present invention are: the mixing barrel, rotating shaft, rotating column, stirring blades, etc. can fully stir the materials in various areas of the mixing barrel, so that the materials are fully mixed to achieve the best mixing effect. Compared with the traditional mixing device, the materials inside and outside the mixing barrel can be fully mixed. This structure is simple, the concept is novel, it is easy to use and has strong practicality.

[0024] It should be pointed out that, according to the needs of implementation, the various components described in the embodiments of the present invention can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of the present invention.

[0025] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
