Description

Technical Field

[0001] This utility model relates to the field of coating dispersion technology, specifically a liquid coating dispersion and homogenization device. Background Technology

[0002] Liquid coatings are industrial products made by adding pigments, fillers, and additives to resins and then diluting and dispersing them with solvents. Due to the wide variety of coating components, differences in specific gravity, and varying reactivity, coatings are actually metastable systems. If mass-produced coatings are not used promptly, the solid components are prone to agglomeration, sedimentation, and clumping at the bottom of the container, leading to deterioration of coating performance and even rendering the coating unusable.

[0003] Currently, industry professionals mainly use three methods to delay and weaken the sedimentation of coatings. The first is to optimize the formula structure during the design stage and add some materials that can prevent sedimentation to the coating system in advance (CN201911085461.2); the second is to ensure uniformity during the mixing stage by continuously stirring the coating with a disperser and a grinder (CN202021869276.0); and the third is to strengthen the sealing ability during the storage stage to avoid oxidation and clumping of the coating (CN202020137447.4).

[0004] These methods can ensure that the coating is uniformly mixed within a certain period, thus preventing sedimentation. However, the corresponding problems are: Method 1 requires professional personnel to design the formula, which demands a high level of technical expertise from practitioners and incurs high research and development costs; Method 2 cannot guarantee the uniformity of the coating during long-term storage; and Method 3 is ineffective for substances with large differences in specific gravity within the coating composition. Therefore, a liquid coating dispersion and homogenization device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a liquid coating dispersion and homogenization device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A liquid coating dispersion and homogenization device includes a housing and a clamping barrel disposed within the housing. One end of the clamping barrel is provided with a detachably connected barrel cover. The bottom of the clamping barrel and the barrel cover are rotatably connected to the inner wall of the housing via a rotating shaft. The housing is provided with a driving part for driving the rotating shaft to rotate. A magnetic stirrer is provided at the bottom of the clamping barrel.

[0007] As a further embodiment of this utility model: the clamping barrel is provided with grippers.

[0008] As a further embodiment of this utility model: the bucket lid and the clamping bucket are connected by a connecting lock, and there are four connecting locks arranged in a circular pattern.

[0009] As a further embodiment of this utility model: the bucket lid is connected to a first rotating shaft via a universal coupling, and the first rotating shaft is rotatably connected to the inner wall of the shell.

[0010] As a further embodiment of this utility model: the bottom of the clamping barrel is connected to a second rotating shaft via a universal coupling, and the second rotating shaft is rotatably connected to the inner wall of the housing.

[0011] As a further embodiment of this utility model: the first rotating shaft and the second rotating shaft are arranged in parallel and are not aligned with each other.

[0012] As a further embodiment of this utility model: the driving unit includes a driving motor disposed within the housing, and the driving motor is poweredly connected to the first rotating shaft or the second rotating shaft through a transmission mechanism.

[0013] As a further embodiment of this utility model: the first rotating shaft or the second rotating shaft is slidably connected to the housing along the axial direction of the first rotating shaft or the second rotating shaft, and the sliding stroke of the first rotating shaft or the second rotating shaft on the housing is less than the length of the first rotating shaft or the second rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This application is equipped with a rotating clamping bucket, which can move the paint bucket before the paint is opened, and thus the paint inside the paint bucket can be stirred by the continuous movement of the entire paint bucket, so as to achieve uniformity of the paint inside the bucket from the outside. 2. This application has a built-in magnetic particle inside the paint bucket and an electromagnetic stirrer is provided at the bottom of the clamping bucket. When the paint bucket is placed in the clamping bucket, the electromagnetic stirrer can cooperate with the magnetic particle inside the paint bucket to stir the paint from the inside of the paint bucket, thereby achieving uniformity of the paint from the inside of the paint bucket. 3. This application starts the equipment before the coating is opened and put into use. Through the combination of the two methods, it can ensure that the liquid coating is always in a rhythmic pulsating state. It can synchronously process the liquid levels of the upper and lower layers of the coating container, remove the sticky substances adhering to the cylinder wall, and help the coating in the center and the periphery of the coating container to frequently exchange, thereby achieving efficient and intelligent coating homogenization.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 In this embodiment of the present invention, a liquid coating dispersion and homogenization device includes a housing 1 and a clamping barrel 2 disposed within the housing 1. One end of the clamping barrel 2 is provided with a detachably connected barrel cover 5. The barrel cover 5 is connected to the clamping barrel 2 via connecting latches 6. There are four connecting latches 6 arranged in a circumferential pattern. The clamping barrel 2 is provided with grippers 4. The grippers can be hydraulic grippers or mechanical grippers. The grippers clamp the material cylinder placed in the clamping barrel 2. In this embodiment, the grippers include multiple clamping blocks. The clamping blocks are threadedly connected to the inner wall of the clamping barrel 2, and an adjustment screw is provided on the outer wall of the clamping barrel 2. Alternatively, other gripper structures can also be used to clamp the material cylinder.

[0018] The bottom of the clamping barrel 2 and the barrel cover 5 are rotatably connected to the inner wall of the housing 1 via a rotating shaft. In this embodiment, the barrel cover 5 is connected to a first rotating shaft 7 via a universal coupling 9. The first rotating shaft 7 is rotatably connected to the inner wall of the housing 1. The bottom of the clamping barrel 2 is connected to a second rotating shaft 8 via a universal coupling 9. The second rotating shaft 8 is rotatably connected to the inner wall of the housing 1. The first rotating shaft 7 and the second rotating shaft 8 are arranged in parallel and are not axially aligned. This makes the rotation of the clamping barrel 2 more complex and allows for better stirring of the material in the barrel. The first rotating shaft 7 or the second rotating shaft 8 is slidably connected to the housing 1 along the axial direction of the first rotating shaft 7 or the second rotating shaft 8. The sliding stroke of the first rotating shaft 7 or the second rotating shaft 8 on the housing 1 is less than the length of the first rotating shaft 7 or the second rotating shaft 8.

[0019] The housing 1 is provided with a drive unit 10 for driving the rotating shaft to rotate. The drive unit 10 includes a drive motor disposed in the housing 1. The drive motor is poweredly connected to the first rotating shaft 7 or the second rotating shaft 8 through a transmission mechanism. The transmission structure can be a transmission belt or a transmission gear set.

[0020] In this embodiment, the drive motor is poweredly connected to the second rotating shaft 8. The second rotating shaft 8 and the housing can only rotate and cannot slide along the axis. The first rotating shaft 7 can both rotate with the housing and slide along the axis of the first rotating shaft 7. This allows the lid 5 to be opened easily when loading materials without interference. At the same time, the sliding distance of the first rotating shaft 7 is less than the length of the first rotating shaft 7. In addition, a limiting device, such as a limiting boss or a limiting pin, is provided at the outermost end of the first rotating shaft 7 to prevent the first rotating shaft 7 from slipping off the housing 1 during rotation.

[0021] A magnetic stirrer 2 is provided at the bottom of the clamping barrel 2. In this embodiment, a magnetic particle is pre-installed inside the barrel before sealing. The outer liner of the magnetic particle must be made of a highly corrosion-resistant material that can withstand the dissolution or corrosion of common organic solvents in the coating, such as anhydrous ethanol, pyrrolidone, dimethyl carbonate, dimethylformamide, etc. In this way, during use, the built-in magnetic particle can cooperate with the magnetic stirrer 2 to magnetically stir the coating.

[0022] In use, when the coating has been stored for a long time and is about to be opened, the coating container is first placed in the clamping barrel 2, and then the barrel is clamped by the jaws 4 inside the clamping barrel 2. Then, the magnetic stirrer 3 is turned on. Since there are magnetic particles inside the barrel, the magnetic particles move continuously inside the barrel under the action of the magnetic stirrer 3, thereby magnetically stirring the material. Then, the drive motor is turned on, which drives the second rotating shaft 8 to rotate. The second rotating shaft 8 drives the clamping barrel 2 to rotate. Since the first rotating shaft 7 and the second rotating shaft 8 at both ends of the clamping barrel 2 are not aligned, the rotating shafts connect to the clamping barrel and move randomly, thereby stirring the coating. Through the continuous rotation of the barrel and magnetic stirring, the material can be effectively stirred before opening.
