Description

Technical Field

[0001] The invention relates to the technical field of grinding, in particular to a grinding device for fluorescent whitening agents. Background Art

[0002] Fluorescent whitening agent is a kind of fluorescent dye, also known as white dye, which is a complex organic compound. Its characteristic is that it can stimulate the incident light to produce fluorescence, so that the dyed substance obtains a glittering effect similar to fluorite, making the substance seen by the naked eye very white, achieving the effect of whitening. Fluorescent whitening agent can absorb invisible ultraviolet light and convert it into blue light or purple visible light with a longer wavelength, compensating for the unwanted yellowish color in the matrix, and at the same time reflecting more visible light in the range of 400-600nm than the original incident wavelength, so that the product appears whiter, brighter and more colorful;

[0003] The grinding device for fluorescent whitening agent is a kind of equipment specially used for the production of fluorescent whitening agent. It grinds the raw crystals of fluorescent whitening agent into fine powder by physical methods to meet the needs of different industrial applications.

[0004] However, as the use time of the fluorescent whitening agent grinding device increases, the grinding disc used to grind the fluorescent whitening agent will gradually wear out. This is because during the grinding process, physical contact and friction will occur between the grinding disc and the fluorescent whitening agent particles. This contact and friction will cause the material on the surface of the grinding disc to be gradually worn away. If the grinding disc is worn too severely and continues to be used, it will cause the workpiece to vibrate, thereby affecting the grinding quality of the fluorescent whitening agent. In addition, the existing fluorescent whitening agent grinding device directly discharges the ground fluorescent whitening agent into the interior of a packaging can or a packaging bag through a pipe port. During this process, a portion of the fluorescent whitening agent will float into the air, and the staff performing packaging operations around the grinding device may inhale the fluorescent whitening agent floating in the air into their bodies. Once the fluorescent whitening agent enters the human body, it is not easy to be decomposed. After combining with proteins, it can only be decomposed by liver metabolism, which will increase the burden on the liver. If excessive contact occurs, it may cause cell mutations and is potentially carcinogenic, which is highly dangerous. Therefore, it does not meet the existing needs. We have proposed a fluorescent whitening agent grinding device. Summary of the invention

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] See also Figures 1 to 6The present invention provides a fluorescent whitening agent grinding device, comprising a fluorescent particle grinding machine housing 1, a fluorescent particle embrittlement processing mechanism 2 is fixedly installed on both sides of the upper end surface of the fluorescent particle grinding machine housing 1, and the fluorescent particle embrittlement processing mechanism 2 comprises a metal shell 201, a feeding port 202, a circular groove 203, a circular plate 206, a plurality of fluorescent particle storage grooves 207, a pushing cylinder 208, a metal ball 209 and a rotating mechanism, the feeding port 202 is located on the outer surface of the top end of the metal shell 201, and the circular groove 203 is located at the lower end of the metal shell 201 and communicates with the inside of the feeding port 202;

[0032] The circular plate 206 is located inside the circular groove 203 and is connected to the circular groove 203 via a roller bearing. The plurality of fluorescent particle receiving grooves 207 are all located on the outer surface of the circular plate 206.

[0033] The metal ball 209 is fixed to the piston rod of the push cylinder 208 . The position of the metal ball 209 corresponds to the position of the fluorescent particle storage groove 207 . The rotating mechanism can drive the circular plate 206 to rotate.

[0034] Furthermore, the rotating mechanism includes a replacement motor 204, the piston rod of which is connected to a replacement shaft 205, which passes through the circular plate 206 from the middle position of the front end surface of the circular plate 206, and the replacement shaft 205 is fixedly connected to the circular plate 206 by socket connection; when the device needs to be used, the fluorescent whitening agent particles to be ground are put into the feeding port 202, and the fluorescent whitening agent particles put into the feeding port 202 will eventually fall into the fluorescent particle receiving groove 207 located in the middle position of the upper end surface of the circular plate 206.
