Description

Technical Field

[0001] The utility model relates to the technical field of powder mixing, in particular to a coating mixer for powder coating production. Background Art

[0002] Thermosetting powder coatings use thermosetting resins as film-forming materials, along with a cross-linking curing agent. Upon heating, they form a hard, insoluble, and infusible coating. Unlike thermoplastic coatings, these coatings will not soften at high temperatures, but will instead decompose. Because the resins used in thermosetting powder coatings are prepolymers with a low degree of polymerization and a low molecular weight, the coatings exhibit excellent leveling and decorative properties. Furthermore, these low-molecular-weight prepolymers, upon curing, form a network of cross-linked macromolecules, resulting in coatings with superior corrosion resistance and mechanical properties. Consequently, thermosetting powder coatings have experienced rapid growth.

[0003] According to a disclosed coating mixer for powder coating production (Announcement No.: CN218475141U), in the process of mixing the powder coating in the above application, only a single mixing is performed. Since the original raw materials are in powder form, the powder itself is very likely to clump when placed in the mixer. The clumped raw materials not only affect the mixing effect, but also easily stick to the bottom of the equipment during the mixing process, resulting in mixing failure. To address this problem, we have proposed a coating mixer for powder coating production. Utility Model Content

The slider passes through the limit frame and is slidably connected to the limit frame. The limit frame is fixedly mounted on the inner wall of the fixed ring. When the ring moves, the movable rod can be folded to push the slider to slide horizontally.

[0009] Preferably, a fixing plate is fixedly mounted on the surface of the slider, and a cone spike is fixedly mounted on the surface of the fixing plate. When the slider moves, the fixing plate can synchronously move laterally.

[0022] The control assembly 7 includes a reciprocating screw 71, which is rotationally connected to the surface of the fixed frame 3. The surface of the reciprocating screw 71 is fixedly connected to the output shaft of the motor 4, and the output shaft of the motor 4 can drive the reciprocating screw 71 to perform circular motion within the fixed frame 3. The reciprocating screw 71 is slidably connected to a slide bar 72. A circular ring 73 is fixedly mounted on the surface of the slide bar 72. A support rod 74 is fixedly mounted on the surface of the ring 73. The support rod 74 passes through the fixed frame 3 and is slidably connected to the fixed frame 3. When the circular ring 73 is subjected to force, it can move longitudinally within the fixed frame 3 under the support of the support rod 74. The surface of the circular ring 73 is hinged to one end of a movable rod 75, and the other end of the movable rod 75 is hinged to the surface of a slider 76. The slider 76 passes through a limit frame 77 and is slidably connected to the limit frame 77. The limit frame 77 is fixedly mounted on the inner wall of the fixed ring 6. When the circular ring 73 moves, the movable rod 75 can be tilted, pushing the slider 76 to slide laterally. A fixed plate 78 is fixedly mounted on the surface of the slider 76, and a spike 79 is fixedly mounted on the surface of the fixed plate 78. When the slider 76 moves, the fixed plate 78 can synchronously move laterally. A swinging member 70 is also provided in the control assembly 7. The swinging member 70 includes a connecting rod 701.
