Description

Technical Field

[0001] This utility model relates to the field of coating production equipment technology, specifically to a powder coating color matching device. Background Technology

[0002] Coatings are liquid or solid materials used for brushing, spraying, or coating surfaces. They are typically used to protect, beautify, or alter the function and appearance of a surface. There are many types of coatings, which can be classified according to their different uses, properties, components, and colors. Common coatings include paints, varnishes, paint emulsions, and paint powders. Coatings are widely used in construction, industry, automobiles, furniture, and home furnishings. In the production process of powder coatings, pigments are mixed with raw materials to create color variations, enriching the colors of the powder coating, improving its visual appeal, and facilitating application. However, in existing color mixing equipment, the powder raw materials tend to solidify after being stored for a certain period. Directly adding this solidified powder raw material into the mixing equipment results in powder clumping, affecting the mixing and preparation effect, leading to uneven pigment mixing, significant color differences in the produced powder coating, and a poor user experience. Therefore, to avoid the shortcomings of existing technologies, it is necessary to improve them. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide a color matching device for powder coatings with high mixing efficiency and small color difference.

[0004] This utility model is achieved through the following technical solution:

Several pigment feeding control devices are installed on the outer side of the top of the mixing tank 1. Several horizontally arranged stirring blades 5 are installed on the upper part of the stirring shaft 3. Several crossbars 6 are installed in the middle of the stirring shaft 3. Several sets of crushing rods 7 are arranged in a ring on the crossbars 6. Several stirring frames 8 are installed at the lower part of the stirring shaft 3. When the powder and pigment are mixed, the powder raw material is first dispersed and initially crushed by the stirring blades 5 to avoid the powder raw material from solidifying. The pigment feeding control devices control the amount of pigment mixed. The crossbars 6 and crushing rods 7 further disperse and crush the powder raw material, and at the same time mix the powder and pigment. Then the stirring frames 8 fully mix the powder and pigment before outputting it, avoiding the powder from clumping, improving the mixing and preparation effect, and making the pigment uniformly mixed. The produced powder coating has a very small color difference, ensuring the use effect of the powder coating and a good user experience.

[0023] The pigment feeding control device includes a feeding box 10, a storage chamber 11 located on the upper part of the inner side of the feeding box 10, a weighing chamber 12 located at the bottom of the storage chamber 11, a first control valve 13 located at the bottom of the storage chamber 11, a weighing device 14 located at the bottom of the weighing chamber 12, an electric push rod 15 connected to the weighing device 14 installed on the lower part of the inner side of the feeding box 10, a buffer chamber 16 located below the weighing chamber 12, and a second control valve 17 located at the bottom of the buffer chamber 16, which enables accurate weighing of pigments and automatic feeding, improves the accuracy of pigment addition, and enhances the mixing and preparation effect of powder coatings.

[0025] The mixing frame 8 is provided with several longitudinal dividing plates 19, which thoroughly mix the powder and pigment.

[0026] A conical guide hood 20 is provided below the feeding hopper 4, which allows the powder raw materials to be initially dispersed when they are fed, making the feeding more uniform and facilitating subsequent thorough mixing.

[0027] The stirring blade 5 is set at an angle, which reduces resistance and makes it easier to disperse powder raw materials, resulting in more uniform mixing.

[0028] The adjacent horizontal bars 6 are staggered, and the crushing rod 7 is set perpendicular to the horizontal bar 6. The crushing rod 7 is firmly connected to the horizontal bar 6, which improves the stability and uniformity of the mixing.

[0030] The discharge pipe 9 is equipped with a discharge control valve 21 for convenient control of the discharge.

[0031] The bottom of the color mixing tank 1 is equipped with several support feet 22 to ensure that the color mixing equipment is placed stably and used stably.
