Technical Field
[0001] This utility model relates to the field of grinding equipment technology, and more specifically, to a carbon black grinding device for pigment paste production. Background Technology
[0002] In the field of color paste production, carbon black is an important colorant and reinforcing agent. The grinding quality of its particles has a key impact on the quality and performance of the color paste. Good grinding effect can make carbon black evenly dispersed in the color paste, thereby improving the coloring power, stability and rheological properties of the color paste. Currently, the industry commonly uses grinding discs to grind carbon black particles. Traditional grinding methods only grind carbon black particles once, which has revealed many drawbacks in actual production. On the one hand, single grinding is insufficient to fully break down carbon black particles, resulting in uneven particle size distribution and some particles failing to meet the ideal fineness requirements, thus affecting the dispersibility and coloring effect of the pigment. On the other hand, the single grinding mode leads to low grinding efficiency. When carbon black particles are not fully ground, operators often need to perform secondary grinding, which prolongs the production cycle, increases production costs, and makes it difficult to meet the growing market demand. Therefore, improvements are needed. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] like Figures 1 to 5 As shown, this utility model provides a carbon black grinding device for pigment paste production, comprising: Grinding box 1, with a first grinding disc 2 movably fitted inside grinding box 1; The grinding mechanism is located at the top of the grinding box 1; The grinding mechanism includes a drive motor 4, the bottom of which is fixedly connected to the top of the grinding box 1. A rotating shaft 5 is fixedly sleeved at the output end of the drive motor 4. A second grinding disc 3 is fixedly sleeved at the bottom of the rotating shaft 5. A grinding channel is left between the top of the second grinding disc 3 and the first grinding disc 2. A grinding channel is left between the bottom of the second grinding disc 3 and the grinding box 1. A drive toothed pulley 6 is fixedly sleeved on the outer surface of the rotating shaft 5. A dustproof shell 7 is movably sleeved on the outer surface of the rotating shaft 5. The outer surface of the dustproof shell 7 is fixedly sleeved with the inner surface of the outer surface of the grinding box 1. A fixed shaft 8 is fixedly sleeved inside the dustproof shell 7. A driven toothed pulley 9 is movably sleeved on the outer surface of the fixed shaft 8. The driven toothed pulley 9 is connected to the drive toothed pulley 6 through a toothed belt 10. A toothed ring 11 is meshed with the outer surface of the driven toothed pulley 9. The bottom of the toothed ring 11 is fixedly connected to the top of the first grinding disc 2.
[0015] When the drive motor 4 is running, the rotating shaft 5 will simultaneously drive the second grinding disc 3 and the drive toothed pulley 6 to rotate. When the drive toothed pulley 6 rotates, it will drive the driven toothed pulley 9 to rotate around the fixed shaft 8 via the toothed belt 10. Since the fixed shaft 8 is meshed with the toothed ring 11, when the fixed shaft 8 rotates, it will drive the first grinding disc 2 to rotate in the opposite direction via the toothed ring 11. Because the first grinding disc 2 and the second grinding disc 3 rotate in opposite directions, the carbon black particles inside the first grinding disc 2 can be ground. The gap between the second grinding disc 3 and the grinding box 1 is inclined, so the carbon black powder after grinding will move into the gap between the second grinding disc 3 and the grinding box 1, and fall to the bottom of the grinding box 1 under the action of gravity. Since the bottom of the grinding box 1 is inclined, the carbon black powder can be guided to the gap between the second grinding disc 3 and the bottom of the grinding box 1. At this time, the second grinding disc 3 will roll the carbon black powder into the gap between the second grinding disc 3 and the grinding box 1 during rotation, and then perform secondary grinding on the carbon black powder.
[0016] The grinding box 1 is fitted with a dustproof ring 12 inside. The bottom end of the dustproof ring 12 is movably connected to the top end of the first grinding disc 2, and the outer surface of the dustproof ring 12 is fixedly connected to the outer surface of the dustproof shell 7.
[0017] Due to the design of the dustproof ring 12 and the dustproof housing 7, the drive toothed pulley 6, the driven toothed pulley 9, the toothed belt 10 and the toothed ring 11 can be well protected, preventing dust from contacting these components and affecting the transmission efficiency.
[0018] The grinding box 1 has a feed pipe 13 fixedly connected to the inside of the top of the grinding box 1, and a discharge pipe 14 fixedly installed at the bottom of the grinding box 1.
[0019] The design of the feed pipe 13 makes it easy for operators to feed materials into the grinding box 1, and the design of the discharge pipe 14 allows the carbon black powder after grinding to move out of the grinding box 1 through the discharge pipe 14.
[0020] Among them, a stirring blade 15 is fixedly sleeved on the outer surface of the rotating shaft 5. The end of the stirring blade 15 away from the rotating shaft 5 is in contact with the interior of the first grinding disc 2, and the bottom end of the stirring blade 15 is in contact with the top end of the second grinding disc 3.
[0021] When the rotating shaft 5 rotates, it will drive the stirring blade 15 to rotate. Due to the design of the stirring blade 15, when the stirring blade 15 rotates, it will be able to drive the carbon black particles inside the first grinding disc 2 to move towards the gap between the first grinding disc 2 and the second grinding disc 3.
[0022] Among them, a fixing ring 16 is fixedly sleeved on the outer surface of the grinding box 1, and a bracket 17 is fixedly installed at the bottom end of the fixing ring 16.
[0023] Due to the design of the fixing ring 16 and the bracket 17, the grinding box 1 will provide good support for the whole, so that the grinding box 1 can be placed stably on the ground.
[0024] The bottom end of the discharge pipe 14 is fixedly sleeved with a conveying pipe 18, the rear end of the conveying pipe 18 is fixedly installed with a power motor 19, the output end of the power motor 19 is fixedly sleeved with a long shaft 20, the outer surface of the long shaft 20 is provided with an auger 21, and the auger 21 is movably sleeved with the inside of the conveying pipe 18.
[0025] When the ground carbon black powder falls into the conveying pipe 18 through the discharge pipe 14, the operator starts the power motor 19. At this time, the long shaft 20 will drive the auger 21 to rotate. Due to the design of the auger 21, the carbon black powder inside the conveying pipe 18 can be conveyed when the auger 21 rotates.
[0026] Working principle and usage process of this utility model: When the operator needs to grind carbon black particles, the operator first pours the carbon black particles into the grinding chamber 1 through the feed pipe 13. These particles will then fall onto the top of the first grinding disc 2. Due to the inclined design of the top of the first grinding disc 2, the carbon black particles will slide down the guide at the top of the first grinding disc 2 into its interior. The operator then starts the drive motor 4. At this time, the rotating shaft 5 will simultaneously drive the drive belt pulley 6, the stirring blade 15, and the second grinding disc 3 to rotate. Due to the design of the stirring blade 15, when the stirring blade 15 rotates, it will cause the carbon black particles inside the first grinding disc 2 to move, causing the carbon black particles to move towards the space between the first grinding disc 2 and the second grinding disc 3. The movement occurs at the seam. Since the outer surface of the driving toothed pulley 6 is meshed with the toothed belt 10, and the toothed belt 10 is meshed with the outer surface of the driven toothed pulley 9, when the driving toothed pulley 6 rotates, it will drive the driven toothed pulley 9 to rotate around the fixed shaft 8 via the toothed belt 10. Since the outer surface of the driven toothed pulley 9 is meshed with the outer surface of the toothed ring 11, when the driven toothed pulley 9 rotates, it will drive the toothed ring 11 to rotate in the opposite direction. At this time, the first grinding disc 2 will rotate in the opposite direction under the drive of the toothed ring 11. Since the rotation direction of the first grinding disc 2 is opposite to that of the second grinding disc 3, when the first grinding disc 2 and the second grinding disc 3 rotate, they can grind the carbon black particles inside the first grinding disc 2. Because the gap between the first grinding disc 2 and the second grinding disc 3 is inclined, the ground carbon black powder will move into the gap between the second grinding disc 3 and the grinding box 1, and then fall to the bottom of the grinding box 1. Since the bottom of the grinding box 1 is inclined, it can guide the carbon black powder well, so that the carbon black powder can automatically move to the gap between the second grinding disc 3 and the bottom of the grinding box 1. When the second grinding disc 3 rotates, it can roll the carbon black powder into the gap between the second grinding disc 3 and the grinding box 1. At this time, the second grinding disc 3 will perform secondary grinding on the carbon black powder during the rotation process, thus realizing the function of automatic secondary grinding of carbon black particles to ensure that the carbon black particles are fully ground.
[0027] After the second grinding disc 3 finishes grinding the carbon black powder, the carbon black powder will enter the discharge pipe 14 through the bottom of the grinding box 1. Then, the carbon black powder will fall into the conveying pipe 18 through the discharge pipe 14. At this time, the operator starts the power motor 19, and the long shaft 20 will drive the auger 21 to rotate. Due to the design of the auger 21, when the auger 21 is running, it will convey the carbon black powder inside the conveying pipe 18.
