Description

Technical Field

[0001] This utility model belongs to the field of chemical machinery technology, specifically, it relates to a grinding device with adjustable viscosity of resin pigment paste. Background Technology

[0002] In industries such as coatings, inks, and cosmetics, the preparation of resin color pastes is a key process, as their viscosity and grinding fineness directly affect the quality and performance of the final product. Traditional resin color paste grinding equipment typically uses fixed-gap grinding mechanisms, such as three-roll mills or ball mills, which have the following technical drawbacks:

[0003] Traditional equipment cannot adjust the gap between the grinding roller and the filter plate in real time during operation, resulting in inaccurate control of pigment viscosity. It requires repeated grinding or changing equipment parameters, which affects production efficiency. After grinding, the resin pigment needs to be separated by the filter plate, but high-viscosity materials are easy to clog the filter pores. Traditional equipment relies on manual cleaning or machine shutdown for vibration, which reduces continuous production capacity.

[0004] To address the aforementioned issues, this application proposes a grinding device with adjustable viscosity for resin pigments. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a resin pigment adjustable viscosity grinding device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A resin pigment adjustable viscosity grinding device includes a tank, a feed hopper is installed on the top of the tank, four symmetrically arranged support legs are fixedly installed on the bottom of the tank, a filter plate is fixedly installed on the inner wall of the tank, a positioning plate is fixedly installed on the inner wall of the tank, and a drive shaft is movably connected to the positioning plate.

[0008] The grinding mechanism includes a mounting plate that is slidably mounted on a drive shaft. Three support plates are fixedly mounted on the bottom of the mounting plate. Grinding rollers are rotatably connected between adjacent support plates. The grinding rollers cooperate with the filter plate.

[0009] The adjustment mechanism includes a rotating shaft that is rotatably mounted on a positioning plate and is connected to the mounting plate via a transmission connection.

[0010] Preferably, the grinding mechanism further includes a circular side plate, which is fixedly installed on the two outer support plates of the three support plates and cooperates with the two grinding rollers.

[0011] The circular side plates allow for easy shielding of the resin abrasive, preventing it from entering the edges of the filter plate and affecting the grinding effect.

[0012] Preferably, the adjustment mechanism further includes two hinge rods, and two symmetrically arranged sliding grooves are provided on one side of the positioning plate. The rotating shaft is rotatably installed on the inner wall of the two sliding grooves, and the rotating shaft is provided with two symmetrically arranged threads. Two moving blocks are slidably connected to the inner wall of the sliding grooves. The two moving blocks are threadedly connected to the rotating shaft. The hinge rods are rotatably connected to the corresponding moving blocks. A connecting block is rotatably connected to the top of the mounting plate, and the connecting block is rotatably connected to the two hinge rods.

[0013] The rotating shaft is connected to two moving blocks by two symmetrically arranged threads, which can drive the two moving blocks to move in opposite directions. The moving blocks are limited by sliding connection with the sliding groove. The moving blocks are rotated by hinge rod, and the hinge rod is rotated by connecting block, which can drive the mounting plate to rise and fall, thereby adjusting the distance between the grinding roller and the filter plate, and thus adjusting the grinding fineness.

[0014] Preferably, a motor is fixedly installed on one side of the tank, a rotating rod is fixedly installed on the output shaft of the motor, a first bevel gear is fixedly installed at one end of the rotating rod, a second bevel gear is slidably installed on the drive shaft, the first bevel gear and the second bevel gear mesh with each other, and a positioning box is fixedly installed on the positioning plate, the positioning box is rotatably connected to the rotating rod, the positioning box is movably connected to the drive shaft, and the second bevel gear is rotatably connected to the inner wall of the positioning box.

[0015] The motor's output shaft drives a rotating rod to rotate. The rotating rod, through the meshing of a first bevel gear and a second bevel gear, drives the second bevel gear to rotate. The second bevel gear is slidably connected to the drive shaft. The second bevel gear has a fan-shaped hole, and the drive shaft has a fan-shaped cross-section. The straight surface on the fan-shaped surface and the fan-shaped hole form a limit, thereby limiting the lateral position between the second bevel gear and the drive shaft. This allows the second bevel gear to move only up and down on the drive shaft, enabling it to drive the drive shaft to rotate when it rotates. At the same time, the second bevel gear is rotatably connected to the inner wall of the positioning box, thus achieving positioning.

[0016] Preferably, a rotating roller is fixedly installed at the top end of the drive shaft, two fixed rods are fixedly installed at the top of the positioning plate, and the same fixed ring is fixedly installed between the two fixed rods. The fixed ring is connected to the rotating roller in a transmission manner, and a striking ball is fixedly installed at the bottom end of the drive shaft. The striking ball cooperates with the filter plate.

[0017] Preferably, the outer side of the roller is provided with a cam groove, and a slider is slidably connected to the inner wall of the cam groove. The slider is fixedly connected to the inner side of the fixed ring.

[0018] The drive shaft drives the rotating roller to rotate. The rotating roller is slidably connected to the slider through the cam groove, and the positioning plate is fixed to the fixing ring through the fixing rod, which can limit the slider. This allows the rotating roller to move up and down automatically while rotating, and then drive the striking ball to strike and vibrate the filter plate through the drive shaft.

[0019] In summary, the technical effects and advantages of this utility model are as follows:

[0020] 1. Dynamic adjustment mechanism for grinding fineness

[0021] The bidirectional moving block is driven to move in the opposite direction by the threaded shaft. Combined with the linkage of the hinge rod and the connecting block, the mounting plate is raised and lowered, thereby dynamically adjusting the distance between the grinding roller and the filter plate. The grinding fineness can be adjusted without stopping the machine, and the viscosity of the pigment paste can be directly controlled, improving the flexibility and efficiency of the process.

[0022] 2. Anti-clogging filter and vibration-assisted system

[0023] Cam-slider vibration mechanism: The drive shaft cooperates with the fixed slider through the cam groove of the rotating roller to convert the rotational motion into periodic up-and-down vibration, which drives the striking ball to hit the filter plate. The automatic vibration prevents the filter holes from clogging, ensures that the ground slurry is filtered quickly, and reduces the need for manual cleaning. Attached Figure Description

The connecting block 75 is rotatably connected to the two hinge rods 74. The rotating shaft 73 is threadedly connected to the two moving blocks 72 through the two symmetrically arranged threads, thereby driving the two moving blocks 72 to move in opposite directions. Through the sliding connection between the moving blocks 72 and the sliding grooves 71, the moving blocks 72 can be limited. The moving blocks 72 are rotatably connected to the hinge rods 74, and the hinge rods 74 are rotatably connected to the connecting block 75, thereby driving the mounting plate 61 to rise and fall, thereby adjusting the distance between the grinding roller 63 and the filter plate 3, and thus adjusting the grinding fineness.

[0036] Reference Figure 2 and Figure 3 A motor 8 is fixedly installed on one side of the tank body 1. A rotating rod 9 is fixedly installed on the output shaft of the motor 8. A first bevel gear 11 is fixedly installed on one end of the rotating rod 9. A second bevel gear 12 is slidably installed on the drive shaft 5.

The rotating rod 9 rotates through the meshing of the first bevel gear 11 and the second bevel gear 12. The meshing mechanism drives the second bevel gear 12 to rotate. The second bevel gear 12 is slidably connected to the drive shaft 5. The second bevel gear 12 has a fan-shaped hole, and the cross-section of the drive shaft 5 is fan-shaped. The straight surface on the fan-shaped surface and the fan-shaped hole form a limit, thereby limiting the lateral position between the second bevel gear 12 and the drive shaft 5. This allows the second bevel gear 12 to move only up and down on the drive shaft 5, so that the second bevel gear 12 can drive the drive shaft 5 to rotate when it rotates. At the same time, the second bevel gear 12 is rotatably connected to the inner wall of the positioning box 10, thereby forming a positioning mechanism.

[0037] Reference Figure 2 and Figure 4 A rotating roller 15 is fixedly installed at the top of the drive shaft 5. Two fixed rods 13 are fixedly installed at the top of the positioning plate 4. A fixed ring 14 is fixedly installed between the two fixed rods 13. The fixed ring 14 is connected to the rotating roller 15 in a transmission manner.

The rotating roller 15 is slidably connected to the slider 17 through the cam groove 16. The positioning plate 4 fixes the fixed ring 14 through the fixed rods 13, thereby limiting the slider 17. This allows the rotating roller 15 to move up and down automatically while rotating, thereby driving the striking ball 18 to strike and vibrate the filter plate 3 through the drive shaft 5.

[0038] Working principle: During operation, the resin pigment raw material is placed onto the filter plate 3 inside the tank 1 through the feed hopper 2. Then, the motor 8 is turned on. The output shaft of the motor 8 drives the rotating rod 9 to rotate. The rotating rod 9, through the meshing of the first bevel gear 11 and the second bevel gear 12, drives the drive shaft 5 to rotate. The drive shaft 5 is slidably connected to the mounting plate 61, thereby driving the mounting plate 61 and the grinding roller 63 to rotate. The grinding roller 63 crushes the material on the filter plate 3. The drive shaft 5 drives the rotating roller 15 to rotate. The rotating roller 15 is slidably connected to the slider 17 through the cam groove 16. The positioning plate 4 is fixed to the fixing ring 14 through the fixing rod 13, thereby limiting the slider 17. This allows the rotating roller 15 to automatically move up and down while rotating. The drive shaft 5 drives the striking ball 18 to strike and vibrate the filter plate 3, thereby quickly filtering the grinding material on the filter plate 3. When it is necessary to adjust the fineness of the material to adjust the viscosity of the pigment, the rotating shaft 73 is manually rotated. The rotating shaft 73 is connected to two moving blocks 72 by two symmetrically arranged threads, which can drive the two moving blocks 72 to move in opposite directions. The moving blocks 72 are slidably connected to the sliding groove 71, which can limit the movement of the moving blocks 72. The moving blocks 72 are rotatably connected to the hinge rod 74, and the hinge rod 74 is rotatably connected to the connecting block 75, which can drive the mounting plate 61 to rise and fall, thereby adjusting the distance between the grinding roller 63 and the filter plate 3, and thus adjusting the grinding fineness.
