Description

Technical Field

[0001] This utility model belongs to the field of dispersion disc technology, and specifically relates to a high-speed shear dispersion disc assembly for water-based coatings. Background Technology

[0002] Dispersion discs are core components of equipment in industries such as coatings, inks, and adhesives. They consist of a metal disc (with serrated edges / blades), a drive shaft, and are mostly made of stainless steel. Through high-speed rotation, they generate strong shearing force and turbulence to disperse pigments, fillers, and other materials in a liquid medium to achieve uniform mixing. They are mainly used in coating production to disperse pigments and improve stability, adhesives to mix fillers, electronic pastes to disperse conductive particles, and food and cosmetics to refine powder emulsions. They can shorten the cycle time and improve product performance.

[0003] In response, CN219744484U discloses a disassembly-friendly dispersion disc assembly, including a dispersion component and a connecting component. The dispersion component includes a disc body, and the connecting component includes a screw rod. Since the disc body is provided with a protrusion through a fixed disc and the protrusion is embedded in a groove on the screw rod, the disc body and the screw rod are initially connected. Furthermore, since the outer peripheral surface of the limiting part and the inner wall of the limiting groove are both provided with threads, the disc body and the screw rod are further fixed by the threaded connection. Compared with the existing welding method, the threaded connection can quickly fix the dispersion component and the connecting component, solving the problem of the traditional method of separating the dispersion component and the connecting component by cutting, which facilitates the maintenance and replacement of the dispersion disc assembly.

[0004] Traditional distribution discs mostly use threaded or keyed connections. These two connection methods do not have a secondary reinforcement structure on the surface, so the connection is prone to loosening during use, which poses a certain risk. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed shear dispersion disc assembly for water-based coatings, which has the advantages of rapid installation and secondary reinforcement of the dispersion disc.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-speed shear dispersion disc assembly for water-based coatings, including a connecting shaft, a mounting block detachably connected to the lower end of the connecting shaft, a dispersion disc body welded to the surface of the mounting block, a fixing plate welded to the upper end of the connecting shaft, spring push rods bolted to both sides of the lower surface of the fixing plate, a slip ring bolted to the piston ends of the two sets of spring push rods, and the slip ring is slidably connected to the connecting shaft, and positioning posts are welded to both sides of the lower surface of the slip ring.

[0007] Using the above technical solution: the spring push rod will push the slip ring to slide on the surface of the connecting shaft. During the sliding process, the positioning pin will be positioned inside the positioning plate, thereby reinforcing the locking block.

[0008] The present invention is further configured such that a fixing shell is welded to the surface of the coupling shaft, and connecting shells are welded to both sides of the fixing shell.

[0009] The above technical solution is adopted: the connecting shell is used for connecting the rotating rod.

[0010] The present invention is further configured such that a rotating rod is welded inside the connecting shell, a rotating plate is rotatably connected to the surface of the rotating rod, a torsion spring is sleeved at both ends of the rotating rod, and both ends of the torsion spring are connected between the connecting shell and the rotating plate through spring fixing parts, and a positioning block is welded to one side of the rotating plate, and the positioning block and the mounting block are detachably connected.

[0011] Using the above technical solution: the torsion spring will drive the rotating plate to rotate on the surface of the rotating rod, while simultaneously positioning the positioning block inside the mounting block.

[0012] The present invention is further configured such that a slider is slidably connected to the surface of the connecting shaft, and a sliding plate is welded to both sides of the slider.

[0013] Using the above technical solution: the slider will drive the moving plate to slide on the surface of the connecting shaft.

[0014] The present invention is further configured such that a telescopic spring is connected inside the movable plate by a spring fixing member, and one end of the telescopic spring is connected to a locking block by the spring fixing member.

[0015] Using the above technical solution: the telescopic spring will push the locking block to engage inside the locking hole.

[0016] The present invention is further configured such that a pull rod is welded to one side of the locking block, and the pull rod is disposed inside the telescopic spring; a positioning plate is welded to one end of the pull rod, and the positioning plate is detachably connected to the positioning post; and a locking hole is opened on the surface of the rotating plate, and the locking hole is detachably connected to the locking block.

[0017] The above technical solution uses an external pull rod to move the locking block out of the locking hole, and when the positioning plate is connected to the positioning post, it can prevent the locking block from moving outward.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. The positioning pin can be positioned inside the positioning plate to reinforce the installation of the locking block. This prevents the locking block from disengaging from the limiting position of the rotating plate during the rotation of the connecting shaft.

[0020] 2. The device uses a quick-installation design of a locking block and a locking hole, and an external pull rod to remove the locking block from the locking hole. This eliminates the hassle of tightening screws when connecting screws, and also allows for quick removal of the dispersing disc body. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figure 1 The water-based coating high-speed shear dispersion disc assembly includes a connecting shaft 1, a mounting block 5 detachably connected to the lower end of the connecting shaft 1, a dispersion disc body 2 welded to the surface of the mounting block 5, a fixing plate 401 welded to the upper end of the connecting shaft 1, spring push rods 402 bolted to both sides of the lower surface of the fixing plate 401, and a slip ring 403 bolted to the piston end of both sets of spring push rods 402, and the slip ring 403 is slidably connected to the connecting shaft 1, and positioning posts 404 are welded to both sides of the lower surface of the slip ring 403.

[0028] Brief description of the usage process: The spring rod 402 can push the slip ring 403 to slide on the surface of the connecting shaft 1, and will drive the positioning post 404 to be positioned inside the positioning plate 314, thereby limiting the position of the locking block 310, achieving the effect of facilitating the installation of the dispersing disc body 2.

[0029] Example 2:

[0030] refer to Figure 1-3 A fixed shell 303 is welded to the surface of the connecting shaft 1, and connecting shells 304 are welded to both sides of the fixed shell 303.

[0031] Furthermore, a rotating rod 306 is welded inside the connecting shell 304, and a rotating plate 301 is rotatably connected to the surface of the rotating rod 306. Torsion springs 305 are sleeved on both ends of the surface of the rotating rod 306, and both ends of the torsion springs 305 are connected between the connecting shell 304 and the rotating plate 301 through spring fixing parts. A positioning block 302 is welded to one side of the rotating plate 301, and the positioning block 302 is detachably connected to the mounting block 5.

[0032] Furthermore, a slider 309 is slidably connected to the surface of the connecting shaft 1, and a moving plate 308 is welded to both sides of the slider 309.

[0033] Furthermore, a telescopic spring 312 is connected inside the movable plate 308 via a spring fixing member, and one end of the telescopic spring 312 is connected to a locking block 310 via the spring fixing member.

[0034] Furthermore, a pull rod 313 is welded to one side of the locking block 310, and the pull rod 313 is located inside the telescopic spring 312. A positioning plate 314 is welded to one end of the pull rod 313, and the positioning plate 314 is detachably connected to the positioning post 404. A locking hole 311 is opened on the surface of the rotating plate 301, and the locking hole 311 is detachably connected to the locking block 310.

[0035] Brief description of the usage process: When the slider 309 slides on the surface of the connecting shaft 1, it will drive the moving plate 308 to move and push the positioning block 302 at one end of the rotating plate 301 to be positioned inside the mounting block 5. When the moving plate 308 moves, the locking block 310 will first contact one end of the rotating plate 301. When the locking block 310 is squeezed, it will be compressed into the moving plate 308. When the moving plate 308 continues to move to the appropriate position, the telescopic spring 312 will push the locking block 310 to engage inside the locking hole 311, thereby completing the reinforcement of the rotating plate 301. When the pull rod 313 is pulled out, the locking block 310 will be pulled out from inside the locking hole 311, which makes it easy to remove the positioning block 302 at one end of the rotating plate 301 from inside the mounting block 5, thereby making it easy to disassemble the dispersing disc body 2 and achieving the effect of facilitating the quick installation of the dispersing disc body 2.
