Description

Technical Field

[0001] The invention relates to the technical field of coating preparation, in particular to a mixing device for preparing a photochromic patch coating. Background Art

[0002] Photochromic patch is an innovative product made of photochromic materials. It can change color under the action of light, thereby realizing multiple functions. Due to its unique color-changing properties, it has been widely used in many fields. The coating of the photochromic patch not only realizes the photochromic function, but also enhances the durability and stability of the product, provides additional functions, and plays a role in beauty, decoration, and protection of the substrate.

[0003] A Chinese patent with announcement number CN117619232B discloses a solid material mixing and dissolving tank, which relates to the technical field of chemical pharmaceuticals. The driving source of the solid material mixing and dissolving tank is arranged on the filling cavity, and the stirring rod is connected to the output end of the driving source. The driving source is used to drive the stirring rod to rotate. The guide cylinder is located in the tank body, and the top and bottom ends of the guide cylinder are both connected to the interior of the tank body. The connecting rod is connected to the stirring rod and the guide cylinder respectively. The guide blade includes a first guide blade and a second guide blade. The first guide blade is connected to the inner wall of the guide cylinder, and the second guide blade is connected to the outer wall of the guide cylinder. The rotation directions of the first guide blade and the second guide blade are opposite. The filling cavity is arranged at the top of the inside of the tank body, and the filling cavity is connected to the tank body. The mixing blade is arranged in the filling cavity, and the mixing blade is connected to the stirring rod. This application can improve the situation where solid materials are easily deposited on the inner bottom of the tank body, so that the solid materials can be dispersed more evenly and the stirring effect is improved.

[0004] When making the photochromic patch coating, it is necessary to determine the ratio of photochromic materials, resin base materials, solvents and additives according to specific application needs and performance requirements to ensure that the coating has good photochromic properties, physical properties and chemical properties. When stirring, it is necessary to ensure that the solution is mixed evenly. In the above-mentioned patent, when the resin solution mixed with other materials is stirred, part of the solution may form a wall on the inner wall of the tank that is higher than the liquid level of the solution. When mixing the materials, the stirring speed cannot be too fast. Too fast a speed may cause excessive bubbles to be generated in the solution. Therefore, the stirring efficiency cannot be improved by simply increasing the stirring speed. Some materials that have not been dispersed may form agglomerations after contacting with bubbles and are difficult to disperse, resulting in uneven mixing between the materials, affecting the normal use of the coating. At the same time, bubbles may also cause the coating surface to be uneven, affecting the optical properties of the photochromic patch.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Example: Figure 1-Figure 8 As shown, a mixing device for preparing a photochromic patch coating described in the present invention includes a tank body 1 and a movable plate 2 slidably connected to the inside of the tank body 1, the bottom of the movable plate 2 is a stirring chamber 3, the top of the movable plate 2 is a movable chamber 4, a vacuum pump 5 is installed in the movable chamber 4, the stirring chamber 3 is provided with a stirring mechanism 7, a driving mechanism 6 and an auxiliary mechanism 9, the stirring mechanism 7 includes a group of stirring components 76, the stirring components 76 are attached to the inner wall of the tank body 1, the driving mechanism 6 includes a connecting plate 65, an adjusting mechanism 8 is provided at the bottom of the connecting plate 65, the adjusting mechanism 8 includes an adjusting seat 81 fixedly installed at the bottom of the stirring chamber 3, the top surface of the adjusting seat 81 is non-horizontally arranged, a ball 83 is arranged on the top of the adjusting seat 81, and the connecting plate 65 cooperates with the adjusting seat 81.

[0023] In this embodiment, when stirring the material solution, the valve of the feed port 12 is closed, the vacuum pump 5 is turned on, the air in the stirring chamber 3 is extracted, and the air is discharged from the exhaust port 11 to the outside of the tank body 1, and the driving shaft 61 drives the sleeve 63 to rotate, so that the fixed plate 73 drives the movable wheel 74 to rotate with the driving shaft 61 as the center, and the movable wheel 74 engaged with the fixed wheel 71 rotates while revolving, and the rotating stirring rod 761 is sequentially and cyclically attached to the inner wall of the tank body 1 to stir the solution close to the inner wall of the tank body 1, so that the solution is mixed more evenly. At the same time, when the driving shaft 61 rotates, the ball 83 at the bottom of the connecting plate 65 rolls on the uneven adjustment seat 81, pushing the connecting plate 65, thereby adjusting the height of the movable plate 2, so that the internal pressure of the stirring chamber 3 changes, which is beneficial to the discharge of bubbles generated in the solution due to stirring. At the same time, the auxiliary mechanism 9 cooperates with the stirring mechanism 7 to make the solution mix more evenly, avoiding affecting the subsequent use of the coating solution.

[0024] like Figure 2-Figure 8 As shown, the driving mechanism 6 is equipped to drive the stirring mechanism 7 to rotate through the driving shaft 61 rotatably connected to the tank body 1, and at the same time, the rotation of the connecting plate 65 cooperates with the adjusting mechanism 8 to move the movable plate 2; the driving mechanism 6 also includes a tooth groove 62 opened at the upper end of the driving shaft 61, the driving shaft 61 is connected with a sleeve 63, the sleeve 63 is fixedly connected with an internal tooth 64, the internal tooth 64 cooperates with the tooth groove 62, the bottom of the sleeve 63 is fixedly connected to the connecting plate 65, the driving shaft 61 passes through the connecting plate 65, and the bottom of the driving shaft 61 is connected with a motor; the tooth groove 62 is engaged with the internal tooth 64 and is slidably connected, and the length of the tooth groove 62 is greater than the length of the internal tooth 64; the stirring mechanism 7 is equipped to rotate the stirring assembly 76 under the drive of the driving mechanism 6, stir and mix the solution close to the inner wall of the tank body 1, and reduce the material hanging on the wall; the stirring mechanism 7 also includes a fixed connection to the movable plate 2 A group of connecting rods 72 at the bottom, one end of the connecting rod 72 away from the movable plate 2 is fixedly connected to a fixed wheel 71, a fixed plate 73 is provided at the bottom of the fixed wheel 71, the fixed plate 73 is fixedly connected to the sleeve 63, a group of movable wheels 74 are provided on the top of the fixed plate 73, the movable wheel 74 is meshed with the fixed wheel 71, a fixed shaft 75 is fixedly connected to the bottom of the movable wheel 74, a stirring assembly 76 is fixedly connected to the outer wall of the fixed shaft 75, the fixed shaft 75 rotates and penetrates the fixed plate 73, and the end of the fixed shaft 75 away from the movable wheel 74 is rotatably connected to the top of the connecting plate 65; the stirring assembly 76 is composed of a group of stirring rods 761, and the stirring rods 761 cooperate with the inner wall of the tank body 1; an auxiliary mechanism 9, which is assembled to cooperate with the stirring mechanism 7 to enhance the mixing effect; the auxiliary mechanism 9 includes a stirring blade 92 fixedly connected to the fixed rod 82, and a spiral blade 91 is fixedly connected to the outer wall of the sleeve 63.

[0025] In this embodiment, the tooth groove 62 of the drive shaft 61 is engaged with the internal tooth 64 in the sleeve 63. When the drive shaft 61 rotates, the sleeve 63 is driven to rotate, so that the fixed plate 73 and the connecting plate 65 fixedly connected to the sleeve 63 rotate, and the connecting rod 72 is fixedly connected to the movable plate 2, and the movable plate 2 only moves vertically up and down. At this time, the fixed wheel 71 will not rotate under the restriction of the connecting rod 72, and the rotation of the fixed plate 73 drives the fixed shaft 75 to rotate with the drive shaft 61 as the center of the circle, and the movable wheel 74 fixedly connected to the fixed shaft 75 is meshed with the fixed wheel 71. Therefore, when the fixed shaft 75 rotates around the drive shaft 61, the fixed shaft 75 together with the stirring assembly 76 fixedly connected to the fixed shaft 75 can realize the rotation while orbiting. When the stirring rod 761 of the stirring assembly 76 rotates, the stirring rod 761 will contact the inner wall of the tank body 1, so that the material solution attached to the inner wall of the tank body 1 can be stirred. The top of the stirring assembly 76 is higher than the liquid surface of the solution. Therefore, when the stirring rod 761 scrapes the inner wall of the tank body 1, the wall hanging formed by part of the solution above the liquid surface due to the stirring of the solution can be scraped off. The stirring rod 761 is connected to the fixed shaft 75, and the upper and lower ends of the stirring assembly 76 are restricted. Regardless of the speed, the stability of the rotation state is relatively high when it accelerates or decelerates. Secondly, the stirring assembly 76 and the connecting plate 65 and other structures can form a stable whole, which can improve the mixing effect as the adjustment mechanism 8 moves.

[0026] In this embodiment, if Figure 6-Figure 8 As shown, when the sleeve 63 and the connecting plate 65 rotate, the spiral blade 91 fixedly connected to the sleeve 63 rotates to stir the center position of the stirring chamber 3. The stirring direction of the stirring component 76 is different from that of the spiral blade 91, which is beneficial for the solution inside the tank body 1 to collide under different stirring forces, thereby enhancing the stirring effect and making the material solution mixed evenly. At the same time, when the connecting plate 65 rotates, the fixed rod 82 rotates on the adjustment seat 81 with the drive shaft 61 as the center, and the stirring blade 92 fixedly connected to the fixed rod 82 revolves therewith to stir the solution in the bottom area of ​​the connecting plate 65 to avoid uneven mixing of the bottom solution.

[0027] like Figure 1-Figure 7As shown, the adjusting mechanism 8 is assembled to move on the top surface of the adjusting seat 81 through the ball 83 to adjust the height of the movable plate 2, so that the pressure in the stirring chamber 3 changes, and the bubbles in the solution are discharged faster; the adjusting mechanism 8 also includes a group of slide grooves 84 opened on the movable plate 2, and a group of slide rods 85 are fixedly connected to the top of the inner wall of the tank body 1, and the slide rods 85 correspond to the slide grooves 84. The slide rods 85 pass through the slide grooves 84 and are slidably connected to the slide grooves 84. The bottom of the connecting plate 65 is fixedly connected to a fixed rod 82, and the end of the fixed rod 82 away from the connecting plate 65 is movably connected to the ball 83 Then, the driving shaft 61 rotates and passes through the adjusting seat 81, and the ball 83 is always in contact with the adjusting seat 81; the connecting plate 65 is provided with a through hole, and the vacuum pump 5 cooperates with the stirring chamber 3; the movable plate 2 and the inner wall of the tank body 1 are sealed, and the sliding rod 85 and the sliding groove 84 are sealed. The driving shaft 61 rotates and passes through the movable plate 2 and is movably connected with the movable plate 2; the side wall of the tank body 1 is provided with an exhaust port 11 and a feed port 12, the exhaust port 11 is connected to the movable chamber 4, the feed port 12 is connected to the stirring chamber 3, a valve is installed in the feed port 12, and the height of the feed port 12 is higher than the liquid level of the solution.

[0028] In this embodiment, the drive shaft 61 drives the sleeve 63 and the connecting plate 65 to rotate, and the fixed rod 82 and the ball 83 at the bottom of the connecting plate 65 rotate accordingly. When the ball 83 that is always in contact with the top surface of the adjusting seat 81 rotates with the drive shaft 61 as the center, the ball 83 always rolls on the top surface of the adjusting seat 81. When the drive shaft 61 rotates, the horizontal height of the ball 83 depends on the contact position of the ball 83 and the adjusting seat 81. When the ball 83 contacts the lowest point of the top surface of the adjusting seat 81, the movable plate 2, the connecting plate 65 and the stirring mechanism 7 all move down to the lowest point, and the lower end of the inner tooth 64 inside the sleeve 63 contacts the bottom of the tooth groove 62 on the drive shaft 61. When the ball 83 moves from the lowest point of the top surface of the adjusting seat 81 to the inclined point, the connecting plate 65 is lifted up by the ball 83, so that the connecting plate 65 together with the sleeve 63, the fixed wheel 71 and the fixed plate 7 3 and the movable plate 2 move up, and at the same time, the inner teeth 64 slide upward in the tooth grooves 62. While sliding, the sleeve 63 follows the drive shaft 61 to keep rotating, ensuring that the stirring mechanism 7 can maintain uninterrupted operation. There may be residual gas in the solution, so bubbles may be formed in the solution when the solution is stirred, and the bubbles may be connected with the materials that are not dispersed in time, resulting in agglomeration, affecting the uniformity of mixing. At the same time, the bubbles may also cause the coating surface to be uneven, affecting the optical properties of the photochromic patch. When the movable plate 2 moves up, the slide bar 85 slides in the slide groove 84. At this time, the distance between the solution surface and the movable plate 2 increases, and the pressure in the stirring chamber 3 changes, which helps the bubbles to escape from the solution surface faster, and then the vacuum pump 5 extracts the air out of the stirring chamber 3. When the movable plate 2 moves up and down, the slide bar 85 always penetrates the movable plate 2.

[0029] In this embodiment, if Figure 1As shown, the through holes on the connecting plate 65 allow the solutions in the upper and lower areas of the connecting plate 65 to communicate with each other. When the driving shaft 61 rotates, it drives the sleeve 63, the connecting plate 65, the ball 83, the stirring mechanism 7 and the auxiliary mechanism 9 to move up and down in the tank body 1. When the structure in the solution moves up and down, it can also play a certain degree of mixing effect on the solution.

[0030] Working principle: When the material solution is in use, the valve of the feed port 12 needs to be closed during stirring, so that the stirring chamber 3 is in a sealed state, the vacuum pump 5 is turned on to extract the air in the stirring chamber 3, and the motor of the driving mechanism 6 is started. When the driving shaft 61 rotates, the inner teeth 64 engaged with the tooth grooves 62 on the driving shaft 61 drive the sleeve 63 to rotate, thereby causing the fixed plate 73 and the connecting plate 65 fixedly connected to the sleeve 63 to rotate, and the movable plate 2 cannot rotate under the restriction of the sliding rod 85, and the fixed wheel 71 and the movable plate 2 are connected. There is a connecting rod 72 in between, so that the fixed wheel 71 also only moves up and down vertically, and the fixed plate 73 rotates to drive the movable wheel 74 meshed with the fixed wheel 71 to rotate, and the rotating stirring rod 761 sticks to the inner wall of the tank body 1 during rotation, stirring and mixing the material solution close to the inner wall of the tank body 1, avoiding uneven mixing of the material solution at the edge, and avoiding the wall hanging situation; when the connecting plate 65 rotates, it drives the fixed rod 82 and the ball 83 to rotate with the driving shaft 61 as the center of the circle, and the ball 83 moves on the top surface of the adjustment seat 81 The contact position of the ball 83 and the adjustment seat 81 is different, and the horizontal height of the ball 83 is also different. When the ball 83 moves from the flat position of the adjustment seat 81 to the inclined position of the adjustment seat 81, the horizontal height of the ball 83 gradually increases, reaches the highest point and then gradually decreases. In this process, the ball 83 lifts the connecting plate 65, and the connecting plate 65 moves up together with the sleeve 63, the fixed wheel 71, the fixed plate 73 and the movable plate 2. The inner teeth 64 in the sleeve 63 slide upward in the tooth groove 62, and the movable plate 2 and the fixed wheel 71 move upward. The fixed wheels 71 are movably connected to the drive shaft 61. When the drive shaft 61 rotates, the movable plate 2 and the fixed wheel 71 only move up and down. The fixed wheel 71 is rotatably connected to the top of the sleeve 63. Therefore, when the horizontal height of the sleeve 63 changes, the fixed wheel 71 is driven to move up and down. The fixed wheel 71 drives the movable plate 2 to move up and down, adjusts the distance between the movable plate 2 and the liquid surface of the solution, and discharges the bubbles in the solution. When the sleeve 63 and the connecting plate 65 rotate, the spiral blade 91 and the stirring blade 92 rotate to enhance the mixing effect.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
