Description

Technical Field

[0001] This utility model relates to the field of coating grinding mill technology, and in particular to a coating grinding mill that can accelerate powder slippage. Background Technology

[0002] In modern industrial production, coating grinding mills are key equipment for processing coating raw materials into powder, and their performance directly affects the efficiency and quality of coating production. However, traditional coating grinding mills have the problem of poor powder flow during operation, which not only reduces production efficiency but may also lead to equipment blockage, increased wear and tear, and increased maintenance costs.

[0003] A coating grinding mill with announcement number CN221085804U has the following key technical features: It includes a processing box with a feed hole on its top surface. A feed pipe is fixedly connected inside the feed hole, and a feed hopper is fixedly installed on the top surface of the feed pipe. A feeding assembly is located on both sides of the feed pipe and is used to feed powder coatings into the processing box. Through the cooperation of a fixed plate, a fixed frame, a connecting hole, a feed pipe, a support hole, and baffles, two baffles can be moved outwards to a suitable position. Through the cooperation of a spring, a movable plate, a limiting column, a support block, a fixed plate, and a limiting hole, the position of the two baffles can be determined. The operator controls the speed at which the powder coatings enter the processing box by controlling the gap between the two baffles, preventing the powder coatings from accumulating on the first grinding disc and achieving the desired powder coating feeding effect.

[0004] In the above-mentioned prior art, the powder coating falls into the gap between the first grinding disc and the second grinding disc in the first set, and the coating is ground by the rotation of the second grinding disc. However, the coating particles are subjected to a force in a single direction, which easily forms grinding dead angles, resulting in some particles being over-ground while other particles are not sufficiently refined, thus reducing the uniformity of the coating powder. Therefore, corresponding improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a coating grinding mill that can accelerate powder slippage, thereby solving the problems of poor coating grinding effect and low efficiency of existing coating grinding mills mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coating grinding mill that can accelerate powder sliding, comprising a feeding box, a box door, and a grinding mill body. The box door is movably connected to the outside of the feeding box, a discharge pipe is connected to the bottom of the feeding box, and a material valve is provided on the outside of the discharge pipe. The grinding mill body is connected to the top of the feeding box, and a material inlet is provided at the top of the grinding mill body. A grinding chamber is provided inside the grinding mill body.

[0007] A control panel is connected to the outside of the main body of the grinding mill, a drive mechanism is provided on the outside of the main body of the grinding mill, a discharge port is provided at the top of the discharge box and the discharge port is connected to the bottom of the main body of the grinding mill, a screen is connected inside the discharge box and a vibration component is provided below the screen.

[0008] Preferably, the driving mechanism includes a drive motor, which is supported and connected to the back of the grinding mill body. The output shaft of the drive motor is fixed with a drive shaft, and one end of the drive shaft passes through the grinding mill body and is fixed with a main gear disk. The bottom end of the main gear disk is engaged with a second gear disk, and one side of the second gear disk is engaged with a first gear disk.

[0009] Preferably, a support shaft is fixed inside the second toothed disc, and a support shaft is fixed inside the first toothed disc. One end of both the support shaft and the support shaft extends into the interior of the grinding mill body. Grinding rollers are fixedly sleeved on the outer sides of the drive shaft, the support shaft, and the support shaft, and the grinding rollers are disposed inside the grinding chamber.

[0010] Preferably, one end of the support shaft extends to the outside of the grinding mill body and is connected to a belt drive component, and the other end of the belt drive component is connected to a transition shaft. A first rotating shaft and a second rotating shaft are respectively connected to the lower two sides of the transition shaft, and a power transmission component is connected to the outside of the transition shaft, the first rotating shaft, and the second rotating shaft.

[0011] Preferably, the belt drive consists of pulleys and a belt, with the pulleys sleeved on the support shaft and the transition shaft, and the belt connecting the pulleys.

[0012] Preferably, the power transmission component includes a transmission wheel and a transmission belt, wherein the transmission wheel is respectively sleeved on the transition shaft, the first rotating shaft and the second rotating shaft, and the transmission wheel is connected to the transmission belt.

[0013] Preferably, the vibration assembly includes an impact block fixed to the outside of the transition shaft, and the impact block is located below the screen. One end of the first rotating shaft and the second rotating shaft both extend into the inside of the material box and are uniformly connected to the outside of the shaft with elastic ropes, and one end of each elastic rope is connected to a rubber ball.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the coating grinding mill that can accelerate powder sliding not only has the effect of efficient grinding of solid powder, but also has the effects of screening and vibrating material discharge, so as to accelerate the powder sliding discharge.

[0015] Solid powder falls into the main body of the grinding mill from the feed inlet. The control panel controls the drive motor to work and drive the drive shaft to rotate. Furthermore, under the mutual meshing of the main gear disc, gear disc two, and gear disc one, the support shaft and the bearing shaft can rotate synchronously. This allows the three grinding rollers to work together in the grinding chamber to form a complex grinding trajectory. The solid powder is subjected to the combined action of multiple forces such as compression, shearing, and friction between the rollers, achieving efficient shearing and compression. This results in a narrower particle size distribution and more uniform fineness in the coating, thereby improving the uniformity and efficiency of coating grinding.

[0016] After grinding, the material falls from the discharge port into the discharge box and is screened to avoid uneven grinding. During this process, the support shaft and belt drive make the transition shaft rotate. The power transmission component makes the first and second rotating shafts rotate. The impact block rotates and impacts the screen, making it shake so that the ground material can fall and flow quickly. The elastic rope and rubber ball rotate and impact the inner wall of the discharge box, accelerating the separation and movement of powder particles, reducing the residence time of powder on the box wall, and speeding up the sliding of powder.

[0025] Please see Figures 1-5 The present invention provides the following technical solution:

[0026] Example 1

[0027] To address the issue of low grinding efficiency in existing coating grinding mills, the following technical solution is proposed. Please refer to the following for details. Figure 1 , Figure 2A coating grinding mill that accelerates powder shedding includes a feeding box 1, a box door 2, and a grinding mill body 3. The box door 2 is movably connected to the outside of the feeding box 1. A discharge pipe 13 is connected to the bottom of the feeding box 1, and a material valve is provided on the outside of the discharge pipe 13. The grinding mill body 3 is connected to the top of the feeding box 1, and a feed inlet 301 is provided at the top of the grinding mill body 3. A grinding chamber 302 is provided inside the grinding mill body 3. A control panel 4 is connected to the outside of the grinding mill body 3, and a drive mechanism 5 is provided on the outside of the grinding mill body 3. The drive mechanism 5 includes a drive motor 501, and the drive motor 501 is supported and connected to the back of the grinding mill body 3. On the other hand, a drive shaft 502 is fixed to the output shaft end of the drive motor 501, and one end of the drive shaft 502 passes through the main body 3 of the grinding mill and is fixed to the main gear disk 503. The bottom end of the main gear disk 503 is engaged with a second gear disk 505, and one side of the second gear disk 505 is engaged with a first gear disk 504. A support shaft 506 is fixed inside the second gear disk 505, and a support shaft 507 is fixed inside the first gear disk 504. One end of the support shaft 507 and the support shaft 506 extends into the interior of the main body 3 of the grinding mill. Grinding rollers 6 are fixedly sleeved on the outside of the drive shaft 502, the support shaft 506 and the support shaft 507, and the grinding rollers 6 are set inside the grinding chamber 302.

[0028] In this embodiment, the solid powder of the coating is fed into the main body 3 of the grinding mill through the feed port 301. Then, the control panel 4 drives the drive motor 501, which drives the drive shaft 502 and the main gear disk 503 to rotate. The main gear disk 503 meshes with the second gear disk 505, which in turn causes the second gear disk 505 to rotate. The second gear disk 505 meshes with the first gear disk 504, which in turn causes the first gear disk 504 to rotate. During this process, the drive shaft 502, the support shaft 506, and the support shaft 507 rotate, which drives multiple grinding rollers 6 to rotate in the grinding chamber 302, so as to efficiently crush and grind the solid coating.

[0029] Example 2

[0030] This embodiment differs from Embodiment 1 in that it utilizes a vibration component to achieve rapid falling of solid powder and rapid material discharge. Therefore, the following technical solution is disclosed; please refer to the details. Figure 3 , Figure 4 , Figure 5The top of the feed box 1 is provided with a feed inlet 101, which is connected to the bottom of the grinding mill body 3. A screen 12 is connected inside the feed box 1, and a vibration component is provided below the screen 12. The vibration component includes an impact block 14 fixed to the outside of the transition shaft 8, and the impact block 14 is located below the screen 12. One end of the first rotating shaft 10 and the second rotating shaft 11 both extend into the feed box 1 and are evenly connected to the outside of the shaft. One end of each elastic rope 15 is connected to a rubber ball 16. One end of the support shaft 506 extends to the outside of the grinding mill body 3 and is connected to... There is a belt drive component 7, and the other end of the belt drive component 7 is connected to a transition shaft 8. The first rotating shaft 10 and the second rotating shaft 11 are respectively connected to the lower two sides of the transition shaft 8. The power transmission component 9 is connected to the outside of the transition shaft 8, the first rotating shaft 10 and the second rotating shaft 11. The power transmission component 9 includes a drive wheel and a drive belt. The drive wheel is respectively sleeved on the transition shaft 8, the first rotating shaft 10 and the second rotating shaft 11. A drive belt is connected between the drive wheels. The belt drive component 7 consists of a pulley and a belt. The pulley is sleeved on the support shaft 506 and the transition shaft 8. A belt is connected between the pulleys.

[0031] In this embodiment, when in use, the support shaft 506 in the drive mechanism 5 rotates, cooperating with the belt drive component 7, i.e., the pulley and belt work together to make the transition shaft 8 rotate. Further cooperating with the power transmission component 9, the first rotating shaft 10 and the second rotating shaft 11 rotate. Then, during the process of sieving the ground solid powder using the screen 12, the transition shaft 8 drives the impact block 14 to rotate. During the rotation of the impact block 14, it impacts the screen 12, causing the screen 12 to vibrate. This prevents the screen 12 from clogging and accelerates the rapid flow of the ground coating. In addition, the first rotating shaft 10 and the second rotating shaft 11 drive multiple elastic ropes 15 and rubber balls 16 to rotate. During the rotation of the rubber balls 16, they impact the inner wall of the discharge box 1, generating vibration force, shaking off the coating powder adhering to the inner wall of the discharge box 1, further accelerating the discharge.
