Description

Technical Field

[0001] This utility model relates to the field of powder coating dispersion technology, and more specifically, it relates to a high-efficiency powder coating dispersion device. Background Technology

[0002] A powder coating production disperser is a device used to disperse solid particles in powder coating raw materials into a liquid medium. Its main function is to fully mix the powder coating raw materials with solvents or liquid media to form a uniform coating solution or dispersion. Powder coating production dispersers can accelerate the dispersion process of coating raw materials, improve production efficiency and coating performance, shorten the production cycle, and reduce production costs.

[0003] Most powder coating production dispersers in the existing technology are equipped with one set of dispersing impellers. If only one set is used, uneven dispersion and mixing are likely to occur. Some dispersers are equipped with two sets of dispersing impellers. Although the two sets of dispersing impellers improve the dispersion and mixing effect, the height is generally fixed. This means that they can only be customized according to the requirements, which makes it impossible to produce in a uniform manner, affects production efficiency, and also reduces the applicability of the disperser.

[0004] To address the aforementioned issues, Chinese Patent Publication No. CN221951038U discloses a disperser for powder coating production, comprising a base, a hydraulic rod fixedly connected to the top right side of the base, a hydraulic cylinder fixedly connected to the top left side of the base, a transmission box fixedly connected to the top of the hydraulic rod, a sleeve fixedly connected to the bottom right side of the transmission box, a dispersing shaft disposed inside the sleeve, an impeller threadedly connected to the bottom of the dispersing shaft, a threaded hole opened on the surface of the dispersing shaft, a first arc-shaped block sleeved on one side of the surface of the dispersing shaft, and a second arc-shaped block sleeved on the other side of the surface of the dispersing shaft.

[0005] In the above scheme, the position of the dispersion shaft is fixed, which is suitable for use in mixing tanks with fixed diameter and depth. However, both the shaft and the impeller can only disperse the powder coating in the middle part of the mixing tank, making it difficult to disperse the powder coating at the inner edge of the tank, resulting in uneven dispersion.

[0006] Therefore, a solution needs to be proposed to address this problem. Utility Model Content

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] A high-efficiency powder coating dispersion device, such as Figures 1-2 As shown, the device includes a base 1 and a mounting bracket 2 fixed to the upper surface of the base 1. A mounting plate 3 is slidably connected to the mounting bracket 2 on its side wall, and a moving device for moving the mounting plate 3 is provided on the side wall of the mounting bracket 2.

[0024] The moving device includes a receiving groove 13 disposed on the side wall of the mounting frame 2 and a lead screw 14 rotatably connected to the inner wall of the receiving groove 13. A second motor 15 for driving the lead screw 14 to rotate is fixedly installed on the side wall of the bracket 5. The second motor 15 is a servo motor. The output shaft of the second motor 15 is connected to one end of the lead screw 14. A nut 24 seat 16 is sleeved on the lead screw 14. The nut 24 seat 16 is fixedly connected to the side wall of the mounting plate 3.

[0025] A limiting rod 17 is fixedly connected to the inner wall of the receiving groove 13. A limiting hole is provided on the nut 24 seat 16 for the limiting rod 17 to pass through. As the nut 24 seat 16 moves with the rotation of the lead screw 14, the nut 24 seat 16 will move along the limiting rod 17, so that the nut 24 seat 16 can be more stable during the movement and prevent the nut 24 seat 16 from rotating with the lead screw 14.

[0026] Mounting frame 2 includes a hydraulic rod fixedly mounted on base 1 and a receiving plate fixedly connected to the output end of the hydraulic rod. The aforementioned moving devices are all set on the side wall of the receiving plate. The extension and retraction of the hydraulic rod can facilitate the overall lifting and lowering of the dispersion shaft 6, making it easy to replace the mixing tank. Similarly, the splash guard in the prior art document CN221951038U can also be assembled on the side wall of the dispersion shaft 6, located above the limiting device. The lifting structure of the hydraulic rod and the splash guard are described in detail in the prior art document CN221951038U, and will not be elaborated here.

[0027] A liquid cylinder 4 is fixedly installed on the upper end face of the mounting plate 3. The output shaft of the liquid cylinder 4 extends to the lower part of the mounting plate 3 and is fixedly connected to a bracket 5. A dispersing shaft 6 is rotatably connected to the lower end face of the bracket 5. A motor 7 for driving the dispersing shaft 6 to rotate is fixedly installed inside the bracket 5. The output shaft of the motor 7 is connected to one end of the dispersing shaft 6. A stirring blade 8 is fixedly connected to the side wall of the dispersing shaft 6. A through hole 1 and a through hole 2 are opened vertically on the side wall of the dispersing shaft 6. An upper crossbar 9 and a lower crossbar 10 are respectively inserted into the through hole 1 and the through hole 2. A limiting device for limiting the upper crossbar 9 and the lower crossbar 10 is provided on the side wall of the dispersing shaft 6. A stirring rod 11 is fixedly connected to the ends of the upper crossbar 9 and the lower crossbar 10 that are away from each other. A stirring blade 12 is fixedly connected to the side wall of the stirring rod 11.

[0028] The limiting device includes two fixed plates 18 that are fixedly connected to the side wall of the dispersing shaft 6. The upper crossbar 9 and the lower crossbar 10 are located between the upper and lower fixed plates 18. Each of the two fixed plates 18 has a corresponding fastening hole 19. An insert rod 20 is inserted between the two fastening holes 19. The upper crossbar 9 and the lower crossbar 10 have several insertion holes 21 for the insert rod 20 to pass through. The insertion holes 21 are evenly distributed. A limiting mechanism for limiting the insertion rod 20 is provided at the end of the insert rod 20.

[0029] The limiting mechanism includes a gripping block 22 fixedly connected to one end of the insertion rod 20. The diameter of the gripping block 22 is larger than the diameter of the fastening hole 19. The other end of the insertion rod 20 is fixedly connected to a threaded rod 23. A nut 24 is threaded onto the outer wall of the threaded rod 23. The diameter of the nut 24 is larger than the diameter of the fastening hole 19. Two sets of limiting devices can be symmetrically arranged on the side wall of the dispersing shaft 6.

[0030] A through groove 25 is provided on the side wall of the stirring rod 11 connected to the lower end face of the upper crossbar 9, through which the lower crossbar 10 passes.

[0031] Working principle: When the lead screw 14 is driven by the motor 2 15 to rotate in both directions, the lead screw 14 can drive the nut 24 seat 16 to move back and forth along the lead screw 14. The nut 24 seat 16 can then drive the dispersing shaft 6 and the stirring rod 11 to move through the mounting plate 3, so that the dispersing shaft 6 can adjust the distance between itself and the hydraulic rod in the mounting frame 2, making it easy for the dispersing shaft 6 to be inserted into the mixing tanks of different diameters. At the same time, depending on the diameter of different mixing tanks, the upper crossbar 9 and the lower crossbar 10 can be moved relative to each other, so that the stirring rods 11 on both sides are closer or further apart. The stirring rods 11 on both sides are adjusted to a position close to the edge of the mixing tank, so that one of the insertion holes 21 on the upper crossbar 9 and the lower crossbar 10 is aligned with the fastening holes 19 on the upper and lower sides. Then, the insertion rod 2 is held. The gripping block 22 on the 0 allows the threaded rod 20 to pass through the lower fastening hole 19, the insertion hole 21 on the lower crossbar 10, the insertion hole 21 on the upper crossbar 9, and the upper fastening hole 19 in sequence. Then, the nut 24 is tightened on the threaded rod 23 to limit the upper crossbar 9 and the lower crossbar 10, so that the stirring rod 11 stays in the current position. In this way, when the motor 7 drives the dispersing shaft 6 to rotate, it can drive the stirring rods 11 on both sides to rotate together, and stir and disperse the powder coating at the edge, making the dispersion more uniform and efficient. During the movement of the lower crossbar 10, when the stirring rods 11 on both sides get closer, the lower crossbar 10 can pass through the through groove 25 to avoid the stirring rods 11 from obstructing the movement of the lower crossbar 10.

[0032] When the position of the two stirring rods 11 needs to be readjusted, unscrew the nut 24 from the threaded rod 23, then hold the gripping block 22 and pull the insert rod 20 out of the fastening hole 19 and the insertion hole 21. After the insert rod 20 is no longer obstructed, move the upper crossbar 9 and the lower crossbar 10 again to make it suitable for the dispersion and mixing of more mixing barrels with different diameters.

[0033] During the stirring process, the support 5 can be raised and lowered by the liquid cylinder 4, which can meet the stirring needs of more stirring tanks of different depths. The upper horizontal bar 9 and the lower horizontal bar 10 are fixedly connected to the end away from the stirring rod 11 with a protrusion. The size of the protrusion is larger than the diameter of the through hole one and the through hole two, which can prevent the upper horizontal bar 9 and the lower horizontal bar 10 from falling off the dispersion shaft 6 during the movement.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
