Description

Technical Field

[0001] This utility model relates to the field of pigment dispersion technology, and specifically to a pigment dispersion mechanism. Background Technology

[0002] Coatings are widely used in our daily lives, providing protection, decoration, and special functions to the coated objects. Coatings are mainly composed of film-forming substances (resins), pigments and fillers, additives, and solvents (or water). Unlike dyes, pigments are usually insoluble in the medium used and mostly exist as aggregates. To obtain good tinting strength, hiding power, and color, the pigment aggregates must be opened up and kept stable.

[0003] Application No. CN202320078399.X discloses an organic pigment dispersion mechanism, which includes a cylinder with an outlet and an inlet; a cover plate covering the inlet, one end of which has a toothed ring groove, a main gear rotatably connected to the center of the toothed ring groove, and multiple secondary gears corresponding to the outer periphery of the main gear on the cover plate, each secondary gear simultaneously meshing with the main gear and the toothed ring groove; and stirring blades, each corresponding to one of the secondary gears, the stirring blades being a plate-like structure with a smooth outer wall. This application has the effect of making the dispersion blades of the disperser easy to clean.

[0004] However, this device drives the stirring blade to rotate through the main gear, the auxiliary gear, and the gear ring groove. Under long-term use, the gears are prone to wear, which not only affects the rotation efficiency of the stirring blade, but also reduces the service life of the gears, increasing the equipment maintenance cost and replacement frequency. Therefore, a pigment dispersion mechanism is proposed. Utility Model Content

[0005] To address the problems in the prior art, this utility model provides a pigment dispersion mechanism.

[0006] The technical solution adopted by this utility model to solve its technical problem is a pigment dispersion mechanism, including a turntable. A sleeve is fixedly connected to the outside of the turntable. Two sleeves are arranged opposite each other. An insert plate is movably inserted into the opposite end of each sleeve. One end of the insert plate is fixedly connected to one side of a mounting frame. The mounting frame is arranged in a C-shape. A roller is rotatably installed inside the mounting frame. The bottom end of the roller is fixedly connected to the top end of a connecting rod. A bearing is sleeved on the outside of the connecting rod. The bearing is installed in the inner bottom of the mounting frame. The bottom end of the connecting rod is fixedly connected to the top end of a stirring blade.

[0007] By adopting the above technical solution, the friction between the roller and the inner wall of the cylinder drives the stirring blade to rotate, avoiding gear wear, extending equipment life, reducing maintenance costs, and the rotation of the turntable allows the stirring blade to achieve a compound motion of rotation and revolution. Combined with the corrugated strip cutting the liquid, the dispersion effect is good.

[0008] Specifically, a spring is installed inside the sleeve, one end of the spring is fixedly connected to one end of the insert plate, and the other end of the spring is fixedly connected to the inner side of the sleeve. The end of the insert plate located inside the sleeve is provided with a limiting structure.

[0009] By adopting the above technical solution, the spring pushes the insert plate outward with its own elastic force, which in turn gives the roller an outward thrust, thereby enhancing the friction between the roller and the inner wall of the cylinder.

[0010] Specifically, the top of the turntable is fixedly connected to the output end of the motor, and the motor is fixedly installed at the center of the top of the cover plate.

[0011] By adopting the above technical solution, the motor can drive the turntable to rotate by starting it with an external power source.

[0012] Specifically, a mounting cover is fixedly installed on the top of the cover plate. The mounting cover is fitted onto the outside of the motor. The top of the mounting cover is fixedly connected to the output end of the cylinder. The cylinder is fixedly installed on the top of the bracket.

[0013] By adopting the above technical solution, the cylinder controls the lifting and lowering of the cover plate through the mounting cover: when the cylinder is started, the cover plate drives the turntable, rollers and stirring blades to move down as a whole, so that the rollers accurately fit against the inner wall of the cylinder.

[0014] Specifically, the bracket is arranged in an inverted L-shape, and one side of the bracket is fixedly connected to the outer side of the cylinder.

[0015] Specifically, the cover plate is fastened to the top of the cylinder, and the inner wall of the cylinder is in contact with the surface of the roller.

[0016] The beneficial effects of this utility model are:

[0017] The pigment dispersion mechanism described in this utility model uses the friction between the roller and the inner wall of the cylinder to drive the stirring blade to rotate, which avoids gear wear, extends equipment life, reduces maintenance costs, and allows the stirring blade to achieve a compound motion of rotation and revolution in conjunction with the rotation of the turntable. Combined with the corrugated strip cutting the liquid, the dispersion effect is good. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As one embodiment of this utility model, such as Figures 1-4 As shown, the pigment dispersion mechanism of this utility model includes a turntable 10. A sleeve 9 is fixedly connected to the outer side of the turntable 10. Two sleeves 9 are arranged opposite each other. An insert plate 13 is movably inserted into the ends of the two sleeves 9 that are far apart from each other. One end of the insert plate 13 is fixedly connected to one side of the mounting frame 12. The mounting frame 12 is arranged in a C-shape. A roller 4 is rotatably installed inside the mounting frame 12. The bottom end of the roller 4 is fixedly connected to the top end of the connecting rod 11. A bearing 15 is sleeved on the outer side of the connecting rod 11. The bearing 15 is installed in the inner bottom of the mounting frame 12. The bottom end of the connecting rod 11 is fixedly connected to the top end of the stirring blade 5.

[0026] When in use, the rotating disc 10 rotates, and the sliding fit between the sleeve 9 and the insert plate 13 drives the mounting frame 12 to rotate radially along the rotating disc 10. The C-shaped structure of the mounting frame 12 provides stable support for the roller 4. The roller 4 is driven to rotate by the friction of the inner wall of the cylinder 6. The rotational force is transmitted to the connecting rod 11 through the bearing 15, which ultimately drives the stirring blade 5 to achieve a compound motion of rotation and revolution.

[0027] The present invention also includes a spring 14 installed inside the sleeve 9, one end of the spring 14 being fixedly connected to one end of the insert plate 13, the other end of the spring 14 being fixedly connected to the inner side of the sleeve 9, and a limiting structure being provided at one end of the insert plate 13 located inside the sleeve 9.

[0028] When in use, the spring 14 pushes the insert plate 13 outward with its own elastic force, which in turn gives the roller 4 an outward thrust, which can enhance the friction between the roller 4 and the inner wall of the cylinder 6.

[0029] The present invention also includes that the top end of the turntable 10 is fixedly connected to the output end of the motor 7, and the motor 7 is fixedly installed at the center of the top end of the cover plate 3.

[0030] When in use, the motor 7 can drive the turntable 10 to rotate by starting it with an external power supply.

[0031] The present invention also includes a mounting cover 2 fixedly installed on the top of the cover plate 3, the mounting cover 2 being sleeved on the outside of the motor 7, the top of the mounting cover 2 being fixedly connected to the output end of the cylinder 1, and the cylinder 1 being fixedly installed on the top of the bracket 8.

[0032] When in use, cylinder 1 controls the lifting and lowering of cover plate 3 through mounting cover 2: when cylinder 1 is started, cover plate 3 drives turntable 10, roller 4 and stirring blade 5 to move down as a whole, so that roller 4 accurately fits the inner wall of cylinder 6.

[0033] The present invention also includes that the bracket 8 is arranged in an inverted L-shape, and one side of the bracket 8 is fixedly connected to the outer side of the cylinder 6.

[0034] The present invention also includes that the cover plate 3 is fastened and installed on the top of the cylinder 6, and the inner wall of the cylinder 6 is in contact with the surface of the roller 4.

[0035] In use, the pigment is first poured into the cylinder 6. The cylinder 1 is started to move the cover plate 3 downward, which in turn moves the turntable 10 downward until the cover plate 3 is fastened and installed at the top of the cylinder 6. At this time, the roller 4 is in contact with the inner wall of the cylinder 6. The motor 7 is started by an external power source. The motor 7 drives the turntable 10 to rotate. The rotation of the turntable 10 drives the roller 4 to rotate along the inner wall of the cylinder 6. At the same time, the friction between the roller 4 and the inner wall of the cylinder 6 drives the roller 4 to rotate on its own axis. The rotation of the turntable 10 and the rotation of the roller 4 allow the stirring blade 5 to revolve around the center of the turntable 10 in the cylinder 6 and rotate on its own axis. The wavy strips at both ends of the stirring blade 5 can cut the liquid in the cylinder 6 into multiple fine streams. These multiple fine streams are remixed, resulting in better dispersion of the pigment and higher mixing efficiency with the co-solvent.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
