Description

Technical Field

[0001] The utility model belongs to the technical field of coating production and processing, and particularly relates to a mixing device for coating production and processing. Background Art

[0002] In the production and processing of paint, stirring and mixing is a crucial step. In the process of paint preparation, it is necessary to accurately control the amount of raw materials and pay attention to the accuracy of basic experimental data. The purpose of stirring is to fully mix various raw materials to achieve the expected performance and quality of the paint.

[0003] A Chinese patent with publication number "CN216987433U" discloses a raw material mixing and processing device for the production and processing of water-based paints, which includes a tank body, a No. 1 motor is arranged on the top of the tank body, and the output pipe at the bottom of the No. 1 motor penetrates the tank body and is installed with a No. 1 stirring rod through a coupling, an electric hydraulic push rod is arranged on one side of the top of the tank body, and a No. 2 motor is installed on the top output end of the electric hydraulic push rod through a mounting frame and bolts, a No. 2 stirring rod is arranged at the bottom of the No. 2 motor, and a feed pipe is arranged at one end of the top of the tank body. The utility model is a raw material mixing and processing device for the production and processing of water-based paints, and personnel can determine the amount of liquid medicine through the scale on the surface of the metering tank, and the electric hydraulic push rod can make the No. 2 stirring rod enter the metering tank, and the No. 2 motor can drive the No. 2 stirring rod to rotate, so as to mix a variety of medicines evenly to meet the use needs of personnel, and is suitable for being widely promoted and used.

[0004] Although the above-mentioned device can play a certain mixing and stirring function during use, its internal stirring structure is relatively simple during the specific stirring and mixing process. During the stirring and mixing period, only a rotating shaft and a plurality of horizontal stirring rods cooperate to stir. The stirred and mixed solution is only stirred on a plane, and it is unable to cause the stirred and mixed coating solution to roll violently up and down. During the stirring period, the solution at the top and bottom of the stirring tank is very likely to be unevenly mixed. In order to improve the uniformity of the stirring and mixing, it usually takes a long time to stir to maintain the uniformity. It can be seen that there are certain defects during the stirring period, so it needs to be improved. Utility Model Content

[0025] The first stirring mechanism 6 includes a first motor 61, which is fixedly installed at the lower end of one side of the stirring box 3. The output end of the first motor 61 passes through the stirring box 3 and is fixedly installed with a rotating shaft 62. Two groups of augers 63 are fixedly installed at the inner end of the outer surface of the rotating shaft 62. The threads of the two groups of augers 63 are opposite to each other. The first stirring mechanism 6 is provided inside the stirring box 3. The rotating shaft 62 and the two groups of augers 63 with opposite threads are driven by the first motor 61 to realize the reciprocating flow of the paint in the stirring box 3. At the same time, a second stirring mechanism 8 is provided at the upper end of the stirring box 3. The second motor 861 drives the stirring frame 82 to achieve lateral displacement and rotational stirring at the upper end of the stirring box 3, thereby improving the stirring and mixing efficiency. The bottom of the stirring box 3 adopts a semicircular arc design, which is conducive to the mixing of the paint and convenient for discharging. On the whole, the equipment design is efficient and practical, suitable for the mixing processing of paint solutions, and can significantly improve the uniformity and efficiency of paint mixing.

[0026] refer to Figure 1-Figure 2 , mounting grooves 10 are provided at the lower ends of both sides of the mixing box 3, and electric heating plates 11 are fixedly installed inside the mounting grooves 10. Mounting grooves 10 are added to the lower ends of both sides of the mixing box 3, and electric heating plates 11 are fixedly installed inside these mounting grooves 10. This improved design enables the mixing box 3 to have a heating function. During the mixing process of the paint, the paint in the mixing box 3 can be heated by the electric heating plate 11 as needed to promote uniform mixing of the paint and the progress of certain chemical reactions. This design not only improves the mixing efficiency of the equipment, but also broadens the application range of the equipment, so that it can adapt to more types of paint mixing needs. At the same time, the design of the mounting grooves 10 makes the installation and replacement of the electric heating plate 11 more convenient, and improves the maintenance convenience of the equipment.

[0027] refer to Figure 1-Figure 2 , heat insulation covers 12 are fixedly installed on the lower ends of both sides of the mixing box 3, and the heat insulation covers 12 are arranged on the outside of the electric heating plate 11. The heat insulation covers 12 are fixedly installed on the outside of the electric heating plate 11. The main purpose of this design is to reduce the heat loss generated by the electric heating plate 11 during operation and improve the utilization efficiency of thermal energy. At the same time, it can also prevent operators from directly contacting the high-temperature parts and enhance the safety of the equipment. The use of the heat insulation cover 12 can effectively isolate the heat generated by the electric heating plate 11 and avoid the heat from being directly transferred to the outer wall of the mixing box 3, thereby reducing heat loss. At the same time, the material of the heat insulation cover 12 usually has good thermal insulation performance, which can maintain the stability of its internal temperature and ensure that the electric heating plate 11 can work continuously and stably.

[0028] refer to Figure 4, stirring plates 64 are fixedly installed at both ends of the rotating shaft 62 at equal intervals, and strip grooves 65 are opened on the outer surfaces of the stirring plates 64. The setting of the stirring plates 64 makes the flow of the paint in the stirring box 3 more uniform and sufficient. When the rotating shaft 62 rotates, the stirring plates 64 will rotate with the stirring to stir and mix the paint. The strip grooves 65 on the stirring plates 64 not only reduce the weight of the stirring plates 64 and reduce the load of the motor, but also reduce the resistance of the stirring plates 64 when stirring the paint, making the stirring process smoother and more efficient. Through the cooperation of the stirring plates 64 and the strip grooves 65, the paint can form a tumbling and reciprocating flow in the stirring box 3, thereby achieving more efficient mixing. This design not only improves the uniformity of paint mixing, but also shortens the mixing time, thereby improving the overall work efficiency.

[0029] refer to Figure 1-Figure 3 The second stirring mechanism 8 includes a side rail 81 and a driving assembly 86. The side rail 81 is fixedly installed on both sides of the upper end of the stirring box 3. The inside of the side rail 81 is slidably connected with a sliding block 83. A base plate 84 is fixedly installed between the inner sides of the sliding block 83. Both ends of the base plate 84 are rotatably connected with a longitudinal axis 85. The bottom of the longitudinal axis 85 passes through the base plate 84. The longitudinal axis 85 is located on the outer surface of the bottom of the base plate 84 and a stirring frame 82 is fixedly installed at equal intervals. The driving assembly 86 is fixedly installed inside the top cover 14. The side rail 81 is fixedly installed on both sides of the upper end of the stirring box 3, providing a stable sliding track for the sliding block 83. The sliding block 83 is slidably connected inside the side rail 81, ensuring that the base plate 84 can be smoothly displaced laterally along both sides of the stirring box 3. The base plate 84 is connected between the inner sides of the sliding block 83. The movement of the driving component 86 drives the base plate 84 to move. Both ends of the base plate 84 are rotatably connected with the longitudinal axis 85. The bottom of the longitudinal axis 85 passes through the base plate 84, so that the stirring frame 82 can rotate with the rotation of the longitudinal axis 85. The longitudinal axis 85 is located on the outer surface of the bottom of the base plate 84, and the stirring frames 82 are fixedly installed at equal intervals. These stirring frames 82 rotate with the rotation of the longitudinal axis 85 to achieve stirring of the paint. The driving component 86 is fixedly installed inside the top cover 14 to provide power for the second stirring mechanism 8. Through the drive of the driving component 86, the base plate 84 and the sliding block 83 are prompted to slide, thereby driving the longitudinal axis 85 and the stirring frame 82 to perform lateral displacement and rotational stirring. This design enables the stirring frame 82 to perform lateral displacement and rotational stirring at the upper end of the mixing box 3, further improving the uniformity and efficiency of the paint mixing.

[0030] refer to Figure 1-Figure 3The driving assembly 86 includes a second motor 861, which is fixedly installed in the middle of one side of the top cover 14. The output end of the second motor 861 passes through the top cover 14 and is fixedly installed with a screw rod 862. The outer surface of the screw rod 862 is threadedly connected with a movable block 863. The bottom of the movable block 863 is fixedly connected to the top of the top plate 2. When the driving assembly 86 is operated, the screw rod 862 can be driven by the driving assembly 86 to drive the movable block 863 to move horizontally. The lateral displacement of the lateral movable block 863 can drive the longitudinal axis 85 and the stirring frame 82 to move horizontally and stir, which can enable the device to perform efficient stirring and mixing.

[0031] refer to Figure 1-Figure 3 A rack 864 is fixedly installed on the inner upper end of the side rail 81, and a transmission gear 865 is fixedly installed on the top of the longitudinal axis 85. The transmission gear 865 and the rack 864 are meshingly connected. By arranging the rack 864 and the transmission gear 865 to cooperate, the rack 864 can drive the transmission gear 865 to rotate during the lateral displacement of the longitudinal axis 85, which can improve the stirring and mixing efficiency of the upper end of the inner side of the overall stirring box 3 of the device.

[0032] Principle and advantages of use: By setting the first stirring mechanism 6, during the use of the equipment, the coating solution material required for processing, stirring and mixing can be added into the interior of the stirring box 3 through the feed hopper 5. At this time, the feed hopper 5 is sealed by the regulating valve 4, and the first motor 61 is started to run, and the first motor 61 is used to drive the auger 63 to rotate. Since the threads of the two groups of auger 63 have opposite rotation directions, the rotating shaft 62 drives the auger 63 to rotate toward one side, which can drive the solution to both sides, and the rotating shaft 62 drives the auger 63 to rotate toward the other side, which can drive the solution to flow inward, so that the solution can flow back and forth inside the stirring box 3, and the solution flowing to both sides of the stirring box 3 during the stirring period can be rolled upward and stirred by the stirring plate 64 driven synchronously by the rotating shaft 62, which can promote the efficient rolling and stirring of the raw materials, and the strip groove 65 can reduce the resistance of the stirring plate 64 and reduce the load of the first motor 61. The rolling reciprocating stirring design can improve the overall mixing and processing efficiency of the coating solution of the equipment, and promote the overall mixing and stirring efficiency of the equipment to be high;

[0033] By setting up the second stirring mechanism 8, the device can be operated by starting the second motor 861 during use, and the second motor 861 is used to drive the screw rod 862 to rotate. The rotation of the screw rod 862 can assist in driving the movable block 863 to move laterally inside the top cover 14. At this time, the second motor 861 can be used to rotate forward and reverse, so as to assist in driving the movable block 863 to drive the base plate 84 on the inner side of the side rail 81 to move back and forth. The movable displacement of the base plate 84 can drive the longitudinal axis 85 to move laterally. During the movement of the longitudinal axis 85, the top rack 864 and the transmission gear 865 are engaged and transmitted, so that the longitudinal axis 85 itself can be driven to rotate synchronously, thereby driving the stirring frame 82 to rotate through the longitudinal axis 85. At this time, the rotating shaft 62 is located at the upper end of the stirring box 3 and is in a rotating stirring state while being laterally displaced, which can efficiently stir the tumbling coating solution and improve the overall stirring and mixing efficiency of the device.
