Description

Technical Field

[0001] This utility model relates to the field of grinding and mixing technology, and in particular to an integrated grinding and mixing device for water-based paint. Background Technology

[0002] Water-based paint is a type of coating that uses water as a solvent. Compared to traditional solvent-based paints, water-based paint uses water as a diluent, rather than organic solvents such as toluene or xylene. Water-based paint is typically composed of pigments, resins, additives, and other components. In the production process of water-based paint, pigments need to be ground and mixed with resins to efficiently prepare water-based coatings (such as latex paints and water-based industrial paints).

[0003] In existing technologies, pigments are ground and mixed with resins using a traditional mixing tank combined with a grinding structure. The conventional mixing tank mixes the ground pigments and resins by rotating a single stirring rod in one direction, which cannot ensure that the ground pigments and resins are mixed evenly, thus affecting the production efficiency of water-based paints. Utility Model Content

[0004] In view of this, the present invention provides an integrated grinding and mixing device for water-based paint. The main technical problem to be solved is that the unidirectional rotation of a single stirring rod cannot promote the uniform mixing of the ground pigments and resins.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated grinding and mixing device for water-based paint, comprising a mixing tank, a cover plate above the mixing tank, a bracket fixedly connected to the upper surface of the cover plate, a stirring assembly installed inside the bracket, the stirring assembly comprising a motor, the main body of the motor being fixedly connected to the outer wall of the bracket, a bevel gear being fixedly connected to the output end of the motor, a rotating shaft being rotatably connected inside the bracket, a bevel gear being fixedly connected to the outer wall of the rotating shaft, the rotating shaft being rotatably connected inside the bracket and the cover plate, a rotating shaft being rotatably connected inside the bracket and the cover plate, a bevel gear being fixedly connected to the outer wall of the rotating shaft, the bevel gears being meshed with the bevel gear, the rotating shaft being rotatably connected inside the rotating shaft, two stirring rods being fixedly connected to the outer wall of the rotating shaft, two stirring rods being fixedly connected to the outer wall of the rotating shaft, a discharge pipe being fixedly connected inside the mixing tank, and a valve being installed on the outer wall of the discharge pipe.

[0006] By adopting the above technical solution, motor one drives bevel gear one to rotate, and the rotation of bevel gear one drives bevel gear two and bevel gear three to rotate synchronously in opposite directions, thereby causing shaft one and shaft two to rotate synchronously in opposite directions. This achieves synchronous reverse rotation of two stirring rods one and two stirring rods two, which fully stirs the ground pigments and resins, making them evenly mixed and improving the production efficiency of water-based paints.

[0007] As a further description of the above technical solution: a grinding assembly is installed on the outer wall of the mixing tank. The grinding assembly includes a grinding tank, which is fixedly connected to the outer wall of the mixing tank. A connecting frame is fixedly connected to the outer wall of the grinding tank. A conveying pipe is fixedly connected to the inside of the grinding tank. The conveying pipe is fixedly connected to the inside of the mixing tank.

[0008] By adopting the above technical solution, pigment particles are placed inside the grinding tank for grinding, and after grinding, they enter the mixing tank through the conveying pipe.

[0009] As a further description of the above technical solution: a second motor is fixedly connected to the upper surface of the connecting frame, a third rotating shaft is fixedly connected to the output end of the second motor, the third rotating shaft is rotatably connected inside the connecting frame, a grinding cone is fixedly connected to the outer wall of the third rotating shaft, and a second valve is installed on the outer wall of the conveying pipe.

[0010] By adopting the above technical solution, the second motor drives the third shaft to rotate, which in turn drives the grinding cone to rotate. The grinding cone consists of three cones, and the distance between the three cones and the inner wall of the grinding barrel decreases from large to small, thereby achieving the effect of multi-layer grinding and promoting the grinding and refining of pigment particles.

[0011] As a further description of the above technical solution: a baffle is provided above the grinding barrel, the baffle is movably connected to the outer wall of the rotating shaft three, connecting blocks are fixedly connected to both sides of the outer wall of the baffle, the connecting blocks are slidably connected to the inside of the connecting frame, and a sliding shaft is slidably connected inside the connecting blocks.

[0012] By adopting the above technical solution, the sliding shaft is limited to sliding inside the connecting block, and the connecting block is limited to sliding inside the connecting frame.

[0013] As a further description of the above technical solution: a spring is sleeved on the outer wall of the sliding shaft, a pull plate is fixedly connected to the outer wall of the sliding shaft, and locking pins are fixedly connected to both sides of the outer wall of the pull plate. An insertion hole is opened inside the connecting frame, and the locking pin is slidably connected inside the insertion hole.

[0014] By adopting the above technical solution, pulling the pull plate outward causes the sliding shaft and the locking pin to slide outward, causing the locking pin to slide out of the insertion hole below the connecting frame. Then, moving the pull plate upward causes the connecting block and the baffle to move upward, and the locking pin is inserted into the insertion hole above the connecting frame, so that the baffle is limited and fixed above away from the grinding barrel, which facilitates the addition of pigment particles.

[0015] As a further description of the above technical solution: a controller is fixedly connected to the outer wall of the mixing tank, ear plates one is fixedly connected to both sides of the outer wall of the mixing tank, ear plates two is fixedly connected to both sides of the outer wall of the cover plate, a cylinder is fixedly connected to the upper surface of ear plate one, and the telescopic end of the cylinder is fixedly connected to the lower surface of ear plate two.

[0016] By adopting the above technical solution, the cylinder can drive the second ear plate and the cover plate to move up, causing the cover plate to move away from the mixing tank, thus facilitating the addition of liquids such as resin into the mixing tank.

[0017] By employing the above technical solution, the integrated grinding and mixing device for water-based paint of this utility model has at least the following beneficial effects:

[0018] 1. Compared with the prior art, this integrated grinding and mixing device for water-based paint, through the setting of motor one, conical gear one, rotating shaft one, conical gear two, rotating shaft two, conical gear three, stirring rod one, and stirring rod two, when mixing the ground pigments and resins, etc., the motor one is started to drive the conical gear one to rotate, causing the conical gear two and the conical gear three to rotate synchronously in opposite directions, which in turn drives the rotating shaft one and the rotating shaft two to rotate synchronously in opposite directions, causing the two stirring rods one and the two stirring rods two to rotate synchronously in opposite directions. Through the synchronous reverse rotation of the stirring rods one and the two stirring rods two, the ground pigments and resins are mixed evenly, thus improving the production efficiency of water-based paint.

[0019] 2. Compared with the prior art, this integrated grinding and mixing device for water-based paint, through the arrangement of baffles, connecting blocks, sliding shafts, springs, pull plates, locking pins, and insertion holes, allows for the following operation: When pigment particles need to be added for grinding, pulling the pull plate outward moves the sliding shaft and locking pin, causing the locking pin to slide out of the insertion hole at the bottom of the connecting frame. Then, moving the pull plate upward moves the connecting block and baffle upward, causing the baffle to move away from the grinding barrel. The locking pin is then aligned with the insertion hole at the top of the connecting frame. After releasing the pull plate, the spring drives the sliding shaft, pull plate, and locking pin to reset, causing the locking pin to slide into the insertion hole at the top of the connecting frame. After adding pigment particles, pulling the pull plate outward and then moving it downward again causes the baffle to adhere to the upper surface of the grinding barrel and the locking pin to insert into the insertion hole at the bottom of the connecting frame, thus sealing the grinding barrel and preventing pigment particles from splashing during the grinding process.

The grinding cone 305 consists of three cones, and the distance between the three cones and the inner wall of the grinding barrel 301 decreases from top to bottom, thereby grinding the pigment particles in multiple layers and promoting fine grinding of the pigment particles. A valve 314 is installed on the outer wall of the conveying pipe 306. A baffle 307 is set above the grinding barrel 301.

The telescopic end of the cylinder 105 is fixedly connected to the lower surface of the ear plate 2 106.

[0029] Working principle: First, pull the pull plate 311 outward, causing the sliding shaft 309 and the locking pin 312 to slide outward, causing the locking pin 312 to slide out of the insertion hole 313 at the lower part of the connecting frame 302. Then, move the pull plate 311 upward, causing the pull plate 311 to move the sliding shaft 309, connecting block 308 and baffle 307 upward, aligning the locking pin 312 with the insertion hole 313 at the upper part of the connecting frame 302. Then, release the pull plate 311, causing the spring 310 to move the sliding shaft 309, pull plate 311 and locking pin 312 back to their original positions, causing the locking pin 312 to slide into place. Inside the upper insertion hole 313 inside the connecting frame 302, the baffle 307 is fixed at a position away from the grinding barrel 301. Then, pigment particles are added into the grinding barrel 301. Subsequently, the pull plate 311 is pulled outward. Using the same principle, the locking pin 312 is disengaged from the upper insertion hole 313 inside the connecting frame 302, and the pull plate 311 causes the baffle 307 to move downward, so that the lower surface of the baffle 307 is attached to the upper surface of the grinding barrel 301. The pull plate 311 is then released, allowing the locking pin 312 to be inserted into the lower insertion hole inside the connecting frame 302. Inside 313, the baffle 307 seals the grinding barrel 301 to prevent pigment particles from splashing during grinding. Then, the motor 303 is started to drive the rotating shaft 304 and grinding cone 305 to rotate, making the pigment particles finely ground. After grinding, the valve 314 is opened, and the ground pigment enters the mixing barrel 1 through the conveying pipe 306. Then, the valve 314 is closed, and the cylinder 105 is started to move the cover plate 101 upward, adding resin and other mixtures into the mixing barrel 1. Then, the cylinder 105 moves the cover plate 101 downward to seal the mixture. Above the mixing tank 1, the starting motor 201 drives the bevel gear 202 to rotate. The rotation of the bevel gear 202 drives the bevel gear 204 and bevel gear 206 to rotate synchronously in opposite directions, which in turn drives the rotating shaft 203 and rotating shaft 205 to rotate synchronously in opposite directions. This causes the stirring rod 207 and stirring rod 208 to rotate synchronously in opposite directions, thereby stirring the ground pigment and resin mixture evenly, making the mixture more uniform and improving the production efficiency of water-based paint. When it is necessary to discharge the material, the valve 108 is opened, and the mixed mixture is discharged through the discharge pipe 107.
