Description

Technical Field

[0001] This utility model belongs to the technical field of coating production equipment, and in particular to a slurry grinding device. Background Technology

[0002] In the coating production process, slurry grinding is a crucial step, as its effectiveness directly impacts the quality and performance of the coating. Existing slurry grinding equipment has weak adaptive adjustment capabilities during operation, leading to over-grinding of the slurry, energy waste, and potential damage to the structure of certain functional components in the coating, thus reducing its quality.

[0003] A search revealed a Chinese patent document (authorization announcement number CN217189900U), which discloses a grinding device for paint production. The device includes a grinding box, a lifting drive assembly installed inside the grinding box, a rotary drive assembly connected to the lifting drive assembly, an upper grinding block connected to the rotary drive assembly, a lower grinding block located below the upper grinding block and connected inside the grinding box, a vibration assembly installed at the bottom of the grinding box, a collection box located below the grinding box, and a base for placing the collection box. The lower grinding block is provided with multiple through screening holes. In this invention, under the action of the lifting drive assembly, the rotation drive assembly descends, causing the upper grinding block to descend to the surface of the lower grinding block and press against the surface of the lower grinding block. At the same time, under the action of the rotation drive assembly, the upper grinding block rotates on the surface of the lower grinding block, and the two work together to grind the coating. The device has a rotatable upper grinding block and uses rotational grinding to grind the coating, which improves the grinding efficiency of the coating. This device can meet basic usage requirements, but its adaptive adjustment capability is weak, which may over-grind the slurry, causing energy waste and potentially damaging the structure of some functional components in the coating, thus reducing the quality of the coating. Utility Model Content

[0004] The purpose of this invention is to provide a slurry grinding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slurry grinding device, comprising a grinding barrel for preventing raw materials from splashing out during grinding, wherein the top of the grinding barrel is connected to a feed hopper for slurry entry, and two threaded brackets are symmetrically welded to the outer periphery of the grinding barrel; The two threaded frames are rotatably mounted with adjustable threaded rods. One end of each threaded rod is fitted with an adjusting block. A fixing rod is installed inside the grinding barrel, and the fixing rod completely penetrates the grinding barrel. The other end of the threaded rod is rotatably located inside the fixing rod. Two grinding wheels for grinding slurry are rotatably mounted on the outer circumference of the fixing rod.

[0006] Preferably, the grinding barrel has a grinding disc installed on its vertical inner wall for cooperating with the grinding wheel. A connecting column is connected to the bottom of the grinding disc, and a movable disc is installed at the end of the connecting column away from the grinding disc. Two guide frames are symmetrically connected to the outer periphery of the movable disc.

[0007] Preferably, the bottom of the grinding barrel is connected to a buffer barrel, the outer periphery of the buffer barrel is connected to a discharge plate, a scraper is installed on the vertical inner wall of the buffer barrel, and the bottom of the buffer barrel is connected to a mounting base for support, with four support feet installed on the bottom of the mounting base.

[0008] Preferably, a motor is mounted on the top of the mounting base, and the output shaft of the motor is connected to a drive pulley via a coupling. A transmission belt is connected to the outer periphery of the drive pulley, and a driven pulley is rotatably connected inside the transmission belt.

[0009] Preferably, a rotating frame is connected to the side of the driven pulley, and two limiting bearings for limiting the displacement of the rotating frame are installed on the outer periphery of the rotating frame.

[0010] Preferably, a hollow column is connected to the end of the rotating frame away from the driven pulley, and a spring is connected inside the hollow column.

[0011] Preferably, one end of the spring is connected to the bottom of the movable disk, and two U-shaped grooves are symmetrically arranged on the outer periphery of the hollow column.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This slurry grinding device benefits from the structure of the grinding wheel and grinding disc. The grinding disc and grinding wheel rotate relative to each other, and the grinding wheel grinds the incoming slurry. The ground slurry enters the buffer tank and is finally discharged from the discharge plate. When the grinding intensity needs to be adjusted, the adjusting block is rotated, which drives the threaded rod to move and adjust the gap between the grinding wheel and the grinding disc. Compared with traditional slurry grinding devices, which have weak adaptive adjustment capabilities, this structure can improve the adaptive adjustment capability, prevent over-grinding of slurry, avoid energy waste, reduce damage to the structure of certain functional components in the coating, and improve the quality of the coating.

[0013] Thanks to the spring structure, when this slurry grinding device encounters hard slurry particles, the grinding disc drives the connecting column to press the spring downwards, causing the spring to deform and play a buffering role, thereby protecting the equipment from damage.

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0018] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0019] like Figures 1 to 5 The slurry grinding device shown includes a grinding barrel 3 for preventing raw materials from splashing out during grinding. The top of the grinding barrel 3 is connected to a feed hopper 4 for slurry entry. The slurry to be ground is added into the grinding barrel 3 from the feed hopper 4. Two threaded brackets 301 are symmetrically welded to the outer periphery of the grinding barrel 3. Two threaded brackets 301 have threaded rods 303 rotatably mounted inside for adjustment. One end of each threaded rod 303 is fitted with an adjusting block 302. A fixing rod 304 is installed inside the grinding barrel 3, completely penetrating it. The other end of the threaded rod 303 is rotatably positioned inside the fixing rod 304. Two grinding wheels 305 for grinding the slurry are rotatably mounted on the outer circumference of the fixing rod 304. The rotating bracket 106 drives the hollow column 201 and connecting column 206 to rotate. The connecting column 206 drives the grinding disc 306 to rotate. The grinding disc 306 and the grinding wheels 305... 5. With relative rotation, the grinding wheel 305 grinds the incoming slurry. When it is necessary to adjust the grinding force, rotate the adjusting block 302. The adjusting block 302 drives the threaded rod 303 to move, adjusting the gap between the grinding wheel 305 and the grinding disc 306. Through threaded transmission, the rotational motion is converted into the linear motion of the threaded rod 303. The threaded rod 303 pushes or pulls the mounting bracket of the grinding wheel 305, changing the vertical distance (gap) between the two. After adjustment, the position of the threaded rod can be fixed by locking the nut or positioning pin to prevent the gap from changing due to vibration during the grinding process.

[0020] The grinding barrel 3 has a grinding disc 306 installed on its vertical inner wall for cooperating with the grinding wheel 305. A connecting column 206 is connected to the bottom of the grinding disc 306. A movable disc 204 is installed at the end of the connecting column 206 away from the grinding disc 306. Two guide frames 205 are symmetrically connected to the outer periphery of the movable disc 204.

[0021] The bottom of the grinding tank 3 is connected to the buffer tank 2, and the outer periphery of the buffer tank 2 is connected to the discharge plate 207. The ground slurry enters the buffer tank 2 and is finally discharged from the discharge plate 207. A scraper 208 is installed on the vertical inner wall of the buffer tank 2. The bottom of the buffer tank 2 is connected to the mounting base 101 for support, and four support feet 1 are installed at the bottom of the mounting base 101.

[0022] A motor 102 is mounted on the top of the mounting base 101. The output shaft of the motor 102 is connected to a drive pulley 103 via a coupling. A drive belt 104 is connected to the outer periphery of the drive pulley 103. A driven pulley 105 is rotatably connected inside the drive belt 104. A rotating frame 106 is connected to the side of the driven pulley 105. Two limit bearings 107 are mounted on the outer periphery of the rotating frame 106 to limit its displacement. The motor 102 drives the drive pulley 103 to rotate. The drive pulley 103 rotates through the drive belt 104 and the driven pulley 105. The driven pulley 105 drives the rotating frame 106 to rotate within the limit bearings 107. The drive belt 104 transmits the rotational torque of the drive pulley 103 to the drive pulley 103. The power is transferred to the driven pulley 105 to achieve non-rigid power transmission. The limit bearing 107 can be a deep groove ball bearing, which provides radial and axial positioning references, restricts the overall movement of the bearing, and ensures that the rotation axis of the rotating frame 106 is fixed. The rolling elements roll between the inner and outer raceways, converting the rotational friction of the rotating frame 106 into rolling friction, reducing resistance, and bearing radial loads (such as the centrifugal force of the rotating frame) and a small amount of axial loads (such as the lateral force of the belt drive). When the driven pulley 105 drives the rotating frame 106 to rotate, the inner ring of the moving part and the rolling elements make circumferential motion along the outer raceway of the fixed part, achieving low-friction transmission through rolling contact. At the same time, the symmetry of the deep groove ball bearing is used to ensure the smoothness and coaxiality of the rotating frame rotation.

[0023] A hollow column 201 is connected to one end of the rotating frame 106 away from the driven pulley 105. A spring 203 is connected inside the hollow column 201. One end of the spring 203 is connected to the bottom of the moving disk 204. Two U-shaped grooves 202 are symmetrically arranged on the outer periphery of the hollow column 201. When encountering hard slurry particles, the grinding disk 306 drives the connecting column 206 to press the spring 203 downward. The spring 203 deforms and plays a buffering role, thereby protecting the equipment from damage.

[0024] Working principle In operation, the slurry grinding device first adds the slurry to be ground into the grinding tank 3 through the feed hopper 4. The motor 102 drives the drive pulley 103 to rotate, which in turn rotates via the transmission belt 104 and the driven pulley 105. The driven pulley 105 drives the rotating frame 106 to rotate within the limit bearing 107. The rotating frame 106 drives the hollow column 201 and the connecting column 206 to rotate, which in turn drives the grinding disc 306 to rotate. The grinding disc 306 and the grinding wheel 305... The grinding wheel 305 grinds the incoming slurry as it rotates relative to the grinding wheel 305. The ground slurry enters the buffer tank 2 and is eventually discharged from the discharge plate 207. When the grinding intensity needs to be adjusted, the adjusting block 302 is rotated. The adjusting block 302 drives the threaded rod 303 to move, adjusting the gap between the grinding wheel 305 and the grinding disc 306. When encountering hard slurry particles, the grinding disc 306 drives the connecting column 206 to press the spring 203 downward. The spring 203 deforms, which plays a buffering role, thereby protecting the equipment from damage.
