Description

Technical Field

[0001] This utility model belongs to the field of carbon black grinding technology, and in particular relates to a grinding device for high-gloss water-based carbon black. Background Technology

[0002] High-gloss water-based carbon black is a special type of carbon black material designed specifically for water-based ink systems. It can impart excellent surface gloss to inks while maintaining the high blackness and high tinting strength of carbon black. It is mainly used in the printing, coating and ink industries.

[0003] Currently, the preparation of high-gloss water-based carbon black generally involves multiple steps, including raw material pretreatment, carbonization, and surface modification. The raw material pretreatment stage typically includes crushing and grinding operations. However, existing grinding equipment relies solely on grinding rollers with a fixed spacing to crush materials during the feeding process. Because the gap between the grinding rollers cannot be adjusted in real time for materials of different particle sizes, excessively large particles are prone to jamming or over-crushing, while excessively small particles are further over-crushed, resulting in poor material uniformity. This not only reduces overall work efficiency but also makes it difficult to meet the requirements of high-precision, high-volume production.

[0004] In summary, existing grinding devices cannot adjust the gap between the grinding rollers in real time according to materials of different particle sizes, resulting in insufficient grinding uniformity and reduced working efficiency. Utility Model Content

[0005] This invention provides a grinding device for high-gloss water-based carbon black, which can solve the problem that existing grinding devices cannot adjust the gap between the grinding rollers in real time according to materials of different particle sizes, resulting in insufficient grinding uniformity and reduced working efficiency.

[0006] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a grinding device for high-gloss water-based carbon black is provided, including a grinding chamber, wherein a coarse grinding chamber and a fine grinding chamber are provided in the grinding chamber, and a feed inlet communicating with the coarse grinding chamber is provided on the surface. A coarse grinding assembly, comprising a grinding roller rotatably disposed within a coarse grinding chamber, a material guide channel rotatably disposed on one side within the coarse grinding chamber, and a fine-tuning cylinder rotatably disposed on the inner wall of the coarse grinding chamber with its rod body and the bottom surface of the material guide channel rotatably connected. A fine grinding structure, comprising a rotating rod rotatably disposed within a fine grinding chamber and a set of pulverizing blades fixedly mounted on the rotating rod.

[0007] A further improvement is that the material feeding point of the material guide channel is designed with an arc surface, and a DC servo motor is fixedly installed on the outside of the grinding chamber. The main shaft of the servo motor is connected to the rotating shaft of the grinding roller, and the width of the grinding roller is smaller than the inner diameter of the port of the material guide channel.

[0008] A further improvement is that the bottom surfaces of the coarse grinding chamber and the material guide channel are fixedly connected with mounting ears, and the rod end and the cylinder end of the fine-tuning cylinder are respectively rotatably set in the two mounting ears via a rotating shaft.

[0009] A further improvement is that, after the fine-tuning cylinder is installed, it is tilted to adjust the distance between the material feeding point of the guide channel and the grinding roller.

[0010] A further improvement is that the shredder is divided into two sets of blades that are symmetrically fixedly installed on the upper and lower parts of the rotating rod, and each set of blades is fixedly installed on the rotating rod at equal intervals.

[0011] A further improvement is that it also includes a material control component, which includes a material control channel fixedly installed on the feed inlet, a rotating column rotatably installed in the port of the material control channel, and a number of material control plates fixedly installed on the rotating column in a circular array. The rotating column is driven by a stepper motor externally installed on the side of the material control channel, and the rotating rod is driven by a stepper motor externally installed on the side of the grinding chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a stepper motor on the side of the material control channel to drive a rotating column and several control plates arranged in an array on it to rotate. As the control plates rotate, the flow rate of material falling into the coarse grinding chamber can be precisely controlled, effectively preventing clogging caused by excessive material.

[0013] (2) This utility model allows the material to flow out of the control channel and fall into the inclined guide channel, sliding along the channel to the lowest point (i.e., the discharge point). At this time, the DC servo motor is started to drive the grinding roller to rotate. The grinding roller and the arc surface of the discharge point of the guide channel cooperate with each other to perform preliminary crushing of the material. After the preliminary crushing is completed, the material falls into the fine grinding chamber. Subsequently, the stepper motor on the side of the grinding chamber is started to drive the rotating rod to rotate, and the preliminary crushed material is subjected to more fine and uniform crushing. This design significantly improves the grinding effect of the material and can fully meet higher production requirements.

[0014] (3) The present invention also has a spacing fine-tuning function. By controlling the extension or contraction of the fine-tuning cylinder rod, the spacing between the material feed point of the guide channel and the grinding roller can be finely adjusted, thereby adapting to the crushing requirements of materials with different particle sizes.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figures 1 to 3 As shown, a grinding device for high-gloss water-based carbon black includes a grinding chamber 2, which is provided with a coarse grinding chamber 201 and a fine grinding chamber 202 that are connected to each other, and a feed inlet 21 that is connected to the coarse grinding chamber 201 is provided on its surface. It should be noted that the bottom of the grinding chamber 2 is provided with a discharge port for the fine grinding chamber 202, which is used to discharge the finely ground material; The coarse grinding assembly 1 includes a grinding roller 13 rotatably disposed in the coarse grinding chamber 201, a material guide channel 12 rotatably disposed on one side in the coarse grinding chamber 201, and a fine-tuning cylinder 14 rotatably disposed on the inner wall of the coarse grinding chamber 201 and rotatably connected to the bottom surface of the material guide channel 12. Specifically, the material feeding point of the material guide channel 12 is designed with an arc surface to cooperate with the grinding roller 13 to perform preliminary crushing of the material. A DC servo motor 11 is fixedly installed on the outside of the grinding chamber 2. The main shaft of the servo motor 11 is connected to the rotating shaft of the grinding roller 13. The width of the grinding roller 13 is smaller than the inner diameter of the port of the material guide channel 12. Specifically, the bottom surfaces of the coarse grinding chamber 201 and the material guide channel 12 are fixedly connected with mounting ears 203. The rod end and the cylinder end of the fine adjustment cylinder 14 are respectively rotatably set in the two mounting ears 203 via a rotating shaft. After the fine adjustment cylinder 14 is installed, it is tilted and used to adjust the distance between the material discharge point of the material guide channel 12 and the grinding roller 13 so as to be suitable for crushing materials of different particle sizes. The fine grinding structure 3 includes a rotating rod 31 rotatably disposed within the fine grinding chamber 202 and a set of crushing blades 32 fixedly mounted on the rotating rod 31. Through dual crushing of coarse and fine grinding, the initially crushed material can be further pulverized more finely and uniformly. This design significantly improves the grinding effect of the material and can fully meet higher production demands. Specifically, the pulverizing blade consists of two sets of blades 321 that are symmetrically fixed on the top and bottom of the rotating rod 31. Each set of blades 321 is fixedly installed on the rotating rod 31 at equal intervals. The equidistant arrangement makes the pulverization more uniform and helps to improve the grinding effect. like Figure 2 and Figure 3 As shown in this embodiment, another implementation scheme is also provided, as detailed below: Material control assembly 4 includes a material control channel 41 fixedly installed on the feed inlet 21, a rotating column 42 rotatably disposed in the port of the material control channel 41, and a plurality of material control plates 43 fixedly installed on the rotating column 42 in a circular array. Specifically, the rotating column 42 is driven by a stepper motor externally mounted on the side of the material control channel 41, and the rotating rod 31 is driven by a stepper motor externally mounted on the side of the grinding chamber 2. By activating the stepper motor on the side of the material control channel 41, the motor drives the rotating column 42 and several material control plates 43 arranged in an array on it to rotate. As the material control plates 43 rotate, the flow rate of material falling into the coarse grinding chamber 201 can be precisely controlled, effectively avoiding blockage caused by excessive material.

[0019] like Figures 1 to 3 As shown in this embodiment, it should also be noted that the actual dimensions of each component in the application document are selected and installed according to the actual needs on site. Additionally, it should be noted that this application document only addresses the shortcomings of existing grinding devices, such as the inability to adjust the grinding roller gap in real time according to materials of different particle sizes, resulting in insufficient grinding uniformity and reduced working efficiency; it does not involve other aspects. The working principle of this grinding device for high-gloss water-based carbon black is described below: When using this new solution, the on-site operator must first place the water-based carbon black into the material control channel 41. Next, the stepper motor on the side of the material control channel 41 is started, driving the rotating column 42 and several material control plates 43 arranged in an array on it to rotate. As the material control plates 43 rotate, the flow rate of material falling into the coarse grinding chamber 201 can be precisely controlled, effectively preventing clogging caused by excessive material. After flowing out of the material control channel 41, the material falls into the inclined guide channel 12 and slides along the channel to the lowest point (i.e., the discharge point). At this time, the DC servo motor 11 is started, driving the grinding roller 13 to rotate. The grinding roller 13 and the arc surface of the discharge point of the guide channel 12 cooperate to perform preliminary crushing of the material.

[0020] After initial crushing, the material falls into the fine grinding chamber 202. Then, the stepper motor on the side of the grinding chamber 2 is activated, driving the rotating rod 31 to rotate, further refining and uniformly pulverizing the initially crushed material. This design significantly improves the grinding effect and can fully meet higher production demands.

[0021] In addition, this novel solution also has a fine-tuning function for the spacing. By controlling the extension or retraction of the rod of the fine-tuning cylinder 14, the spacing between the material discharge point of the guide channel 12 and the crushing roller 13 can be finely adjusted, thereby adapting to the crushing requirements of materials with different particle sizes.

[0022] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
