The equipment of this patent is provided with a grinding ring, a grinding ring inner groove, a grinding roller, a rolling blade, a grinding bump, a dust suction mesh cover, a dust suction hole, and a dust suction pipe joint. The gap between the grinding ring inner groove and the grinding roller is larger at the top and smaller at the bottom. Therefore, when the material is rotated and ground by the grinding roller, the particles gradually decrease from top to bottom, and large particles can be directly put in, and the occurrence of inadequate grinding is prevented. At the same time, the rolling blade on the outside of the grinding roller is rotated to play a downward rolling role, and the unevenness of the grinding bump is used to grind faster, thereby increasing the grinding efficiency and more efficient grinding processing.

[0003] When the equipment of this patent is actually used, the raw materials need to be placed between the grinding ring and the grinding roller, and the raw materials are ground by the grinding roller. However, the equipment requires manual feeding of the raw materials, which is labor-intensive and prone to uneven feeding. It is difficult to ensure that the raw materials are evenly scattered in the grinding ring. It is easy for some parts of the grinding roller to have more raw materials and less raw materials, which will cause uneven grinding and affect the grinding effect of the equipment.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When the existing ultrafine grinding equipment is actually used, the raw materials need to be placed between the grinding ring and the grinding roller, and the raw materials are ground by the grinding roller. However, the equipment requires manual feeding of the raw materials, which is labor-intensive and prone to uneven feeding. It is difficult to ensure that the raw materials are evenly scattered in the grinding ring. It is easy for some parts of the grinding roller to have more raw materials and less raw materials, which will cause uneven grinding and affect the grinding effect of the equipment.

[0024] To solve the above defects of ultrafine grinding equipment during use, please refer to Figure 1-Figure 5The utility model provides an ultrafine grinding device for preparing a dispersant for non-metallic materials of lithium batteries, which can realize automatic and uniform feeding, save manpower, improve the uniformity of equipment grinding, and improve grinding efficiency. The ultrafine grinding device uses a grinding ring 1 and a grinding roller 2 arranged in the grinding ring 1 as the basic structure. A driving shaft is arranged on the grinding roller 2, and an external driving device is connected through the driving shaft. The raw material enters between the grinding ring 1 and the grinding roller 2. The driving device drives the grinding roller 2 to rotate to grind the raw material. The grinding roller 2 is a prior art, and its specific structure and grinding principle are not described in detail here. The bottom thread of the grinding ring 1 is installed with a collection seat 10. The raw material after grinding by the grinding roller 2 falls into the collection seat 10. The collection seat 10 can be removed from the grinding ring 1 by rotating the collection seat 10 to collect the material powder, and a mounting ring 3 is fixedly installed on the top of the grinding ring 1. A feeding mechanism 5 is arranged on one side of the top of the mounting ring 3. The feeding mechanism 5 is used to automatically feed the material into the grinding ring 1, wherein the mounting ring 3 The top of the bracket 51 is fixedly connected to the track 4, and the bracket 51 is slidably installed on the outside of the track 4. A material box 6 is fixedly installed on one side of the top of the bracket 51, and a material guide 54 is arranged on the other side of the top of the bracket 51. The raw materials in the material box 6 can fall into the grinding ring 1 along the material guide 54, and the bracket 51 is provided with a driving part 52 for driving the bracket 51 to perform uniform circular motion around the grinding roller 2. The driving part 52 drives the bracket 51 to move, and the bracket 51 drives the material box 6 and the material guide 54 to move synchronously. The material guide 54 can scatter the raw materials evenly around the grinding roller 2, so that the raw materials fall evenly into the grinding ring 1. Compared with traditional manual feeding, the setting of the feeding mechanism 5 can not only save manpower, but also make the raw materials more evenly fed, improve the uniformity of the grinding of the raw materials by the grinding roller 2, and improve the grinding efficiency.

[0025] In order to realize that the support 51 automatically performs uniform circular motion around the grinding roller 2, refer to Figure 3 and Figure 4 As shown, a servo motor 521 is provided, and the servo motor 521 is fixedly installed inside the bracket 51. The output end of the servo motor 521 passes through the bracket 51 and is fixedly connected to a pulley 522. The outer edge of the pulley 522 fits against the outer wall of the track 4. The servo motor 521 is driven to drive the pulley 522 to rotate. The pulley 522 rotates and can roll along the outer wall of the track 4 through the friction between the pulley 522 and the track 4. The pulley 522 rotates along the track 4 to drive the bracket 51 to slide on the track 4. The track 4 and the grinding roller 2 are coaxially arranged, so that the bracket 51 can perform a circular motion around the grinding roller 2.

[0026] In order to improve the sliding smoothness of the bracket 51, auxiliary wheels 523 are symmetrically installed at the bottom of the bracket 51, and the outer edges of the two auxiliary wheels 523 are in contact with the inner wall of the track 4. When the pulley 522 rolls along the outer wall of the track 4, the two auxiliary wheels 523 can be driven by the bracket 51 to rotate along the inner wall of the track 4, and the auxiliary wheels 523 can assist the bracket 51 to slide.

[0027] In order to enable the material box 6 to move with the bracket 51, a reinforcing rod 55 is fixedly connected to the side of the bracket 51, and the material box 6 is fixedly installed on the reinforcing rod 55, and the ends of the reinforcing rod 55 are symmetrically installed with fastening bolts 53 for fixing the material box 6. The reinforcing rod 55 can support the material box 6, and a discharge port 7 is opened on the side of the material box 6 close to the feeding mechanism 5. The inner bottom wall of the material box 6 is inclined, and the discharge port 7 corresponds to the guide piece 54. The material in the material box 6 can roll along its inner bottom wall to the guide piece 54, and fall into the grinding ring 1 along the guide piece 54, and a baffle 8 for blocking the discharge port 7 is slidably installed on the side of the material box 6. When the equipment is not in use, the discharge port 7 can be slid downward to block the baffle 8 to stop feeding. A visual window 9 is installed on the material box 6, through which the remaining raw materials in the material box 6 can be conveniently observed, so as to facilitate the replenishment of raw materials.

[0028] In order to ensure that the raw material can smoothly enter the gap between the grinding ring 1 and the grinding roller 2, a buffer plate 541 is specially provided. The end of the buffer plate 541 is fixedly connected with a discharge plate 542, and anti-fall strips 543 are installed on both sides of the buffer plate 541 and the discharge plate 542. The slope of the buffer plate 541 is smaller than the slope setting of the discharge plate 542. The setting of the buffer plate 541 can prevent the raw material from falling too fast and causing accumulation. The lower end of the discharge plate 542 is set above the gap between the grinding ring 1 and the grinding roller 2. The raw material can smoothly fall into the grinding ring 1 along the discharge plate 542, and the anti-fall strips 543 can prevent the raw material from falling from both sides of the buffer plate 541 and the discharge plate 542.
