Description

Technical Field

[0001] The utility model relates to the technical field of paint production, in particular to a paint mixing device. Background Art

[0002] During the production and use of paint, it is necessary to mix it evenly to ensure the uniform dispersion of pigments, avoid the influence of sediments and solidified substances on the painting effect, activate damping agents and preservatives, and avoid mottling and color difference on the coating. However, the traditional stirring device has poor stirring effect on materials with strong viscosity, and the stirring range of the stirring blades is also small. At the same time, the traditional stirring blades are subject to more resistance during rotation, but they cannot convert the resistance into shear force, increasing energy consumption without enhancing the mixing effect. For this reason, we propose a paint mixing device. Content of the Utility Model

[0003] The purpose of the utility model is to provide a paint mixing device to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a paint mixing device, including a stirring motor, a telescopic cylinder and a stirring barrel;

A star gear is arranged in the middle of the installation ring. The star gear includes a sun gear in the middle and planet gears on the side. The sun gear is fixedly connected to the bottom transmission end of the stirring motor, and the sun gear meshes directly with the planet gears;

[0006] A sealing cover is arranged between the installation ring and the stirring motor. The top of the sealing cover is fixed to the stirring motor by screws, and a rubber ring is arranged at the bottom of the sealing cover. When it moves downward, the rubber ring abuts against the top side of the installation ring;

[0007] A stirring impeller is fixed to the bottom of each planet gear. Arc-shaped stirring blades are evenly arranged on the stirring impeller, and inclined flow disturbing holes are opened on each stirring blade. An auxiliary stirring ring is arranged between adjacent stirring blades.

[0024] Embodiment:

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution for a coating mixing device: including a stirring motor 10, a telescopic cylinder 20, and a stirring cylinder 30;

[0026] A discharge hopper 301 is provided at the bottom of the stirring cylinder 30, a discharge valve 302 is provided at the bottom of the discharge hopper 301, and the discharge valve 302 is in communication with the stirring cylinder 30;

[0027] The stirring motor 10 is arranged on the top of the stirring cylinder 30. An installation ring 102 is provided at the bottom of the stirring motor 10. A star gear 103 is provided in the middle of the installation ring 102. The star gear 103 includes a sun gear in the middle and planet gears on the side. The sun gear is fixedly connected to the bottom transmission end of the stirring motor 10, and the sun gear is directly meshed with the planet gears;

[0028] A sealing cover 101 is provided between the installation ring 102 and the stirring motor 10. The top of the sealing cover 101 is fixed to the stirring motor 10 by screws, and a rubber ring is provided at the bottom of the sealing cover 101. When it moves downward, the rubber ring abuts against the top side of the installation ring 102;

[0029] A stirring impeller 104 is fixed to the bottom of each planet gear. Arc-shaped stirring blades are uniformly arranged on the stirring impeller 104, and inclined flow disturbing holes 105 are opened on each stirring blade. An auxiliary stirring ring 106 is provided between adjacent stirring blades;

[0030] Extension blades 107 are uniformly arranged on the auxiliary stirring ring 106, and shear grooves 108 are opened on the extension blades 107;

[0031] The bottom of the mounting ring 102 is evenly provided with guide rods, and the top of the mixing drum 30 is evenly provided with guide grooves. When the mounting ring 102 moves downward, the guide rods are inserted into the guide grooves at the top of the mixing drum 30; when the mounting ring 102 approaches the mixing drum 30, the guide rods and the guide grooves can play a role in guiding, fixing and restricting the rotation of the mounting ring 102. At the same time, the rubber ring blocks the gap between the bottom of the mounting ring 102 and the top of the mixing drum 30, sealing the gap at the connection, which is very convenient.

[0032] At the top left of the mixing motor 10, a telescopic cylinder 20 is provided. At the bottom of the telescopic cylinder 20, a telescopic rod 201 is provided. At the bottom of the telescopic rod 201, a fixing plate 202 is provided. The fixing plate 202 is in close contact with the left side of the mixing motor 10, and the fixing plate 202 is fixed to the mixing motor 10 by bolts.

[0033] When this solution is in use, the mixing motor 10 provides power for the star gear 103. Its working principle is mainly based on its special gear structure. The planetary gear system consists of a sun gear, planetary gears, a planetary carrier and an external gear ring, and has the characteristics of large torque and large speed ratio. When the mixing motor 10 drives the sun gear to rotate, the planetary gears on the side are synchronously driven to rotate. The planetary gears are restricted between the external gear ring and the sun gear. In addition to revolving around the sun gear, they also rotate on their own under the drive of the sun gear. The mixing impeller 104 installed at the bottom of the planetary gear makes a circular stirring motion in the mixing drum 30 and rotates on its own at the same time, fully stirring the paint in the mixing drum 30 evenly.

[0034] At the same time, evenly arranged turbulence holes 105 are provided on the mixing impeller 104. When the turbulence holes 105 rotate, the paint is sucked in from the pores. Through continuous self-rotation, violent movement is generated. Wherever the turbulence holes 105 pass, the paint is poured in from one side of the turbulence holes 105 and pulled out from the other side, constantly generating disturbances, providing additional fluid motion shear and disturbance circulation through the turbulence holes 105; the motion of the mixing impeller 104 around the sun gear is the outer stirring path, and the self-rotation of the mixing impeller 104 and the disturbance of the turbulence holes 105 are the inner stirring paths, enhancing the mixing effect through the two inner and outer stirring paths.

[0035] The mixing blades on the mixing impeller 104 are arranged at intervals, and gaps are provided between adjacent mixing blades. When the mixing impeller 104 rotates and stirs on its own, shear force can be generated between the gaps and the mixing blades. At the same time, when the mixing impeller 104 moves around the sun gear, the mixing blades with gaps can reduce resistance.

[0036] Meanwhile, an auxiliary stirring ring 106 is provided between adjacent stirring impellers 104. The diameter of the auxiliary stirring ring 106 has three types, including the same length as the diameter of the stirring impeller 104, one-half of the diameter of the stirring impeller 104, and one-third of the diameter of the stirring impeller 104. The diameter of the auxiliary stirring ring 106 shown in the figure is one-third of the diameter of the stirring impeller 104. Select a suitable auxiliary stirring ring 106 according to the viscosity of the paint. For higher viscosity, use an auxiliary stirring ring 106 with a smaller diameter, and for lower viscosity paint, select an auxiliary stirring ring 106 with a larger diameter. The auxiliary stirring ring 106 can also perform a turbulent flow movement during rotation through its own shear groove 108;

[0037] The stirring motor 10, the stirring cylinder 30, and the telescopic cylinder 20 of this solution are all used on the mounting frame. The mounting frame can be freely assembled as needed. It only needs to correspond the installation positions of the stirring motor 10, the stirring cylinder 30, and the telescopic cylinder 20 on the mounting frame; A telescopic cylinder 20 is provided on the top of the stirring motor 10. The telescopic cylinder 20 drives the telescopic rod 201 to move the whole of the stirring motor 10, separating the stirring motor 10 from the stirring cylinder 30, which is very convenient for filling materials and cleaning the inner wall;

[0038] A discharge hopper 301 and a discharge valve 302 are provided at the bottom of the stirring cylinder 30. After opening the discharge valve 302, the mixed paint in the stirring cylinder 30 can be discharged.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention.
