Description

Technical Field

[0001] The present invention relates to the technical field of powder mixing, and specifically provides a dry powder color mixing device for the production of modified composite pigments. Background Art

[0002] Modified composite pigments are functional materials that optimize the structure and enhance the performance of traditional pigments through physical or chemical means. The core lies in endowing pigments with more excellent properties through means such as surface modification and multi-component compounding to meet the comprehensive requirements of modern industry for color, durability, functionality, etc. In the production process of modified composite pigments, a dry powder color mixing device is the core equipment for achieving uniform dispersion of pigments and precise color matching.

The stirring rod inside is rotated through the engine one disposed at the bottom of the box body, and a scraping part is disposed on the inner wall. With the assistance of the engine two, the scraper is driven on the threaded rod one to scrape the inside of the box body.

[0004] However, when the above-mentioned prior art is used, only a single stirring rod stirs unidirectionally, and the stirring rod is located in the upper half of the color mixing tank, making it easy for the powder to settle and agglomerate during mixing, which affects the efficiency of color mixing. Therefore, there is an urgent need for a dry powder color mixing device for the production of modified composite pigments. Summary of the Invention

[0005] Aiming at the above technical deficiencies, the purpose of the present invention is to provide a dry powder color mixing device for the production of modified composite pigments to solve the problems in the above background art.

[0007] The mixing mechanism includes a base and a first motor. A second motor is fixedly connected to the inner side of the base. The output end of the second motor is fixedly connected to a rotating shaft. A connecting frame is fixedly connected to the outside of the rotating shaft. A mixing component is arranged at the bottom of the first motor. A mounting seat is fixedly connected to the inside of the color mixing tank. A connecting rod is rotatably connected to the inside of the mounting seat. A flow guiding plate is fixedly connected to the outside of the connecting rod. A first gear is fixedly connected to the outside of the connecting rod. A toothed ring is meshed with the outside of the first gear. A second gear is meshed with the outside of the toothed ring;

[0008] The anti-caking mechanism includes a feed pipe and a carbon fiber shell. An ion wind ring is installed inside the feed pipe. A cavity is formed inside the color mixing tank. A spiral heating pipe is installed inside the cavity. Thermal grease is installed inside the cavity;

[0009] The separation mechanism includes a tank cover. A separation seat is fixedly connected to the outside of the tank cover. A first cylinder is installed at the bottom of the separation seat. The bottom of the first cylinder is fixedly connected to a support seat. One end of the support seat is fixedly connected to a second cylinder.

[0010] Preferably, the mixing component includes a stirring shaft. Stirring rollers and cutting blades are fixedly connected to the outside of the stirring shaft.

[0011] Preferably, one end of the stirring shaft is fixedly connected to the output end of the first motor. A plurality of stirring rollers and cutting blades are provided.

[0012] Preferably, one end of the connecting frame is fixedly connected to one end of the color mixing tank. The bottom of the color mixing tank is movably connected to the top of the base. The first motor is fixedly connected to the top of the tank cover. The flow guiding plate is arranged in an arc shape. A driving shaft is fixedly connected to the middle of the second gear. A third motor is installed at the bottom of the driving shaft.

[0013] Preferably, a plurality of mounting seats are provided. The plurality of mounting seats are arranged in an annular array. The connecting rod penetrates through the tank cover and extends to the top of the tank cover.

[0014] Preferably, the feed pipe is fixedly communicated with the top of the tank cover. The carbon fiber shell is sleeved on the outside of the stirring roller.

[0015] Preferably, an electric heating pipe is installed inside the spiral heating pipe. One end of the electric heating pipe is electrically connected to a storage battery.

[0016] Preferably, a sealing gasket is installed at the bottom of the tank cover. Two first cylinders are provided.

[0017] Preferably, one end of the second cylinder is fixedly connected to a fixed seat. One end of the fixed seat is fixedly connected to the outer wall of the color mixing tank.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0019] First, in the present invention, powder enters the interior of the color mixing tank through the feed pipe. Then, by starting the second motor inside the base to rotate, the connecting frame outside the rotating shaft is driven to rotate, thereby driving the color mixing tank connected to the connecting frame to rotate circumferentially. Since the bottom of the color mixing tank is movably connected to the top of the base, the circumferential rotation of the color mixing tank is more stable. As the color mixing tank rotates circumferentially, the powder is promoted to spiral upward along the tank wall to form an annular flow layer. At the same time, the first motor is started to drive the stirring shaft to rotate, thereby driving the stirring roller and the cutting blade to rotate for color mixing operation of the powder. The cutting blade cuts the powder to avoid caking. The stirring direction of the stirring roller is opposite to the rotation direction of the color mixing tank, which can form a turbulent vortex, reduce the layering phenomenon, avoid powder settlement and shorten the powder circulation path, thereby shortening the powder mixing time. At the same time, a torque sensor is installed outside the stirring shaft. When the torque of the stirring shaft is detected to decrease, the third motor drives the drive shaft to rotate, thereby driving the second gear to rotate, which in turn drives the gear ring to rotate, and then drives a plurality of first gears meshing with the inside of the gear ring to rotate simultaneously, so that the connecting rod rotates, and then drives the deflector to rotate, enabling the inclination angle of the deflector to be adjusted according to the mixing power consumption, thereby enhancing the turbulence, increasing the powder circulation speed, shortening the mixing time, and thus achieving the effect of improving the powder mixing efficiency of the modified composite pigment.

[0020] Second, in the present invention, an ion wind ring is installed inside the feed pipe. When the powder enters the interior of the color mixing tank, the ion wind ring is started to blow air to neutralize the charge on the surface of the powder, thereby eliminating the static electricity of the powder and avoiding caking during feeding. At the same time, a carbon fiber shell is installed on the stirring roller to prevent the powder from adhering to the stirring roller. At the same time, the carbon fiber shell eliminates frictional static electricity, further avoiding powder caking. Then, the connecting valve outside the spiral heating pipe is connected to an external water pump and water pipe, so that hot water can enter the spiral heating pipe, thereby heating the interior of the color mixing tank to avoid powder damp adhesion. A heat insulation layer is provided outside the color mixing tank to prevent heat from affecting the outer wall of the color mixing tank. At the same time, the cavity is filled with thermal conductive silicone grease to reduce heat loss and improve the heating effect, thereby achieving the effect of avoiding powder caking.

[0021] Third, in the present invention, by starting the first air cylinder to push the separation seat upward, the tank cover is driven to rise, so that the mixing assembly rises, and the connecting rod disengages from the mounting seat. Then, the mixing assembly, the deflector and other devices can be removed from the color mixing tank. Then, by pushing the support seat with the second air cylinder, the tank cover is moved away from the upper part of the color mixing tank. Then, the first air cylinder contracts, causing the tank cover to descend, so that the staff can clean the mixing assembly, the color mixing tank and the deflector separately, avoiding cleaning dead corners of the mixing assembly and the deflector, and thus achieving the effect of convenient cleaning.

Detailed Embodiments

[0030] The following will further describe in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. Detailed Embodiment 1

[0032] The following is a specific embodiment of a dry powder color mixing device for the production of modified composite pigments.

[0033] Please refer to Figure 1-7 , a dry powder color mixing device for the production of modified composite pigments, comprising a color mixing tank 1, a mixing mechanism 2 is arranged inside the color mixing tank 1, an anti-caking mechanism 3 is arranged on the inner side of the color mixing tank 1, and a separation mechanism 4 is arranged on the top of the color mixing tank 1;

[0034] The mixing mechanism 2 includes a base 21 and a first motor 22. A second motor 23 is fixedly connected to the inner side of the base 21. The output end of the second motor 23 is fixedly connected to a rotating shaft 24. A connecting frame 25 is fixedly connected to the outside of the rotating shaft 24. A mixing component 26 is arranged at the bottom of the first motor 22. A mounting seat 27 is fixedly connected to the inside of the color mixing tank 1. A connecting rod 28 is rotatably connected to the inner side of the mounting seat 27. A guide plate 29 is fixedly connected to the outside of the connecting rod 28. A first gear 201 is fixedly connected to the outside of the connecting rod 28. A gear ring 202 is meshed with the outside of the first gear 201. A second gear 203 is meshed with the outside of the gear ring 202;

[0035] Through the above technical solution, the powder material enters the inside of the color mixing tank 1 through the feed pipe 31. Then, the second motor 23 inside the base 21 is started to rotate, which drives the connecting frame 25 outside the rotating shaft 24 to rotate, thereby driving the color mixing tank 1 connected to the connecting frame 25 to rotate circumferentially. Since the bottom of the color mixing tank 1 is movably connected to the top of the base 21, the circumferential rotation of the color mixing tank 1 is more stable. When the color mixing tank 1 rotates circumferentially, it promotes the powder material to spiral upward along the tank wall to form an annular flow layer. At the same time, the first motor 22 is started to drive the stirring shaft 204 to rotate, which drives the stirring roller 205 and the cutting blade 206 to rotate to perform the color mixing operation on the powder material. The cutting blade 206 cuts the powder material to avoid caking. The stirring direction of the stirring roller 205 is opposite to the rotating direction of the color mixing tank 1, which can form a turbulent vortex, reduce the layering phenomenon, avoid the sedimentation of the powder material and shorten the circulation path of the powder material, thereby shortening the mixing time of the powder material. At the same time, by installing a torque sensor on the outside of the stirring shaft 204, when the torque of the stirring shaft 204 is detected to decrease, the third motor drives the drive shaft to rotate, which drives the second gear 203 to rotate, thereby driving the gear ring 202 to rotate, and then driving a plurality of first gears 201 meshed with the inside of the gear ring 202 to rotate simultaneously, so that the connecting rod 28 rotates, and then driving the guide plate 29 to rotate, so that the inclination angle of the guide plate 29 can be adjusted according to the mixing power consumption, thereby enhancing the turbulence, increasing the circulation speed of the powder material and shortening the mixing time, so as to achieve the effect of improving the powder mixing efficiency of the modified composite pigment. The electrical equipment such as motors is powered by a storage battery. The storage battery is installed on the tank cover 41, which is convenient for the color mixing tank 1 to rotate and avoid interference. The storage battery power supply is a prior art, so it will not be described in detail.

[0036] The anti-caking mechanism 3 includes a feed pipe 31 and a carbon fiber shell 32. An ion wind ring 33 is installed inside the feed pipe 31. A cavity is opened inside the color mixing tank 1. A spiral heating pipe 34 is installed inside the cavity. A thermal conductive silicone grease 35 is installed inside the cavity;

[0037] Through the above technical solution, by installing an ion wind ring 33 inside the feed pipe 31, when the powder enters the inside of the color mixing tank 1, the ion wind ring 33 is started to blow out air to neutralize the charge on the surface of the powder, thereby eliminating the static electricity of the powder, avoiding caking during feeding. At the same time, by installing a carbon fiber shell 32 on the stirring roller 205, it is avoided that the powder adheres to the stirring roller 205. At the same time, the carbon fiber shell 32 eliminates frictional static electricity, further avoiding powder caking. Then, the electric heating tube in the spiral heating tube 34 starts to heat, thereby heating the inside of the color mixing tank 1 to avoid moisture adhesion of the powder. A heat insulation layer is provided outside the color mixing tank 1 to prevent heat from affecting the outer wall of the color mixing tank 1. At the same time, the cavity is filled with thermal conductive silicone grease 35 to reduce heat loss and improve the heating effect, thereby achieving the effect of avoiding powder caking.

[0038] The separation mechanism 4 includes a tank cover 41. The outside of the tank cover 41 is fixedly connected with a separation seat 42. A first cylinder 43 is installed at the bottom of the separation seat 42. The bottom of the first cylinder 43 is fixedly connected with a support seat 44.

Then, by pushing the support seat 44 with the second cylinder 45, the tank cover 41 is moved away from above the color mixing tank 1. Then the first cylinder 43 contracts, causing the tank cover 41 to descend, so that the staff can clean the mixing assembly 26, the color mixing tank 1 and the deflector 29 separately, avoiding cleaning dead corners of the mixing assembly 26 and the deflector 29, thereby achieving the effect of convenient cleaning.

[0048] Specifically, the feed pipe 31 is fixedly communicated with the top of the tank cover 41, and the carbon fiber shell 32 is sleeved outside the stirring roller 205.

[0049] Through the above technical solution, by sleeving the carbon fiber shell 32 outside the stirring roller 205, it is convenient for the subsequent disassembly of the carbon fiber shell 32.
