Description
Technical Field
[0001] This utility model relates to the field of coating liquid preparation technology, and in particular to a coating liquid preparation device. Background Technology
[0002] In nylon coating-related industries, such as the functional coating processing of high-end textile fabrics and the preparation of nylon composite materials for precision electronic packaging, the quality of the coating solution is one of the core elements of the product. The coating solution required for nylon coating not only needs to have a precise chemical composition ratio, but also needs to meet extremely high standards in terms of mixing uniformity and viscosity stability. This makes the performance of the coating solution preparation device a key factor affecting the smoothness of the production process and the quality of the product.
[0003] Existing coating liquid preparation devices typically employ a relatively simple stirring structure. Commonly, a single, fixed-shape and angled stirring blade is mounted on a motor-driven stirring shaft. The motor drives the stirring blade to rotate within the preparation tank, thereby mixing various raw materials. In terms of raw material transportation, ordinary pipelines are generally used to directly transport the raw materials to the preparation tank, lacking any mixing treatment during the raw material transportation process.
[0004] However, traditional coating liquid preparation devices have a prominent problem: they are difficult to adaptively adjust to the changes in the characteristics of the coating liquid at different stages of the preparation process. In actual preparation, as the raw materials are mixed, the viscosity, flowability, and other properties of the coating liquid will continuously change. However, the existing stirring structure, due to the fixed angle of the stirring blades, cannot make corresponding adjustments to these characteristic changes. As a result, in the later stages of preparation, when the viscosity of the coating liquid increases, the stirring effect is greatly reduced, making it difficult to achieve sufficient mixing of the raw materials and seriously affecting the quality of the coating liquid preparation. To address this problem, a coating liquid preparation device is proposed. Utility Model Content

[0032] 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.
[0033] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a coating liquid preparation device, comprising a preparation tank 1, which is made of stainless steel and has good corrosion resistance and strength. The preparation tank 1 is used to contain raw materials and provide space for the preparation of coating liquid. A feeding component is provided at the top of the preparation tank 1, which is used to transport various raw materials required for preparing coating liquid into the preparation tank 1. A discharge component is provided at the bottom of the side wall of the preparation tank 1, which is used to discharge the prepared coating liquid out of the preparation tank 1. A stirring component is provided inside the preparation tank 1, which is responsible for stirring and mixing the raw materials in the preparation tank 1 to fully integrate the raw materials and achieve the required coating liquid performance. A power component is provided at the bottom of the stirring component, which is located at the bottom of the preparation tank 1 and provides power to the stirring component to drive the stirring component to operate.
[0034] The stirring assembly includes a fixed box 8, made of stainless steel. The fixed box 8 is used to install and protect components such as bevel gear 11, bevel gear 2 12, and transmission rod 14, and also serves as a support structure for the stirring blade 15. A drive motor 2 10 is fixedly connected to the bottom of the fixed box 8. The drive motor 2 10 provides power for the rotation of bevel gear 11, thereby controlling the angle adjustment of the stirring blade 15. The output end of the drive motor 2 10 is fixedly connected to bevel gear 11 via a key connection. Multiple bevel gears 2 12 are provided on the outer wall of bevel gear 11, meshing with each other. Both bevel gear 11 and bevel gear 2 12 are made of alloy steel, possessing high strength and wear resistance. The rotation of bevel gear 11 is achieved through meshing. Multiple bevel gears 12 rotate to transmit power and change direction, thereby driving the stirring blade 15 to rotate and adjust its angle. The bevel gears 12 are arranged in a circumferential pattern inside the fixed box 8. Each bevel gear 12 is fixedly connected to a transmission rod 14, made of stainless steel, which transmits the rotation of the bevel gears 12 to the stirring blade 15, causing it to rotate. Multiple sealing rings 13 are installed inside the fixed box 8. The sealing rings 13 prevent liquid from the preparation tank 1 from entering the fixed box 8, affecting the normal operation of components such as the bevel gear 11 and bevel gear 12, while ensuring smooth rotation of the transmission rods 14. The sealing rings 13 are arranged in a circumferential pattern, and their outer walls are fixedly connected to the inside of the fixed box 8. The outer walls of all four components are rotatably connected to the sealing ring 13 via bearings. Stirring blades 15 are fixedly connected to the side walls of the transmission rod 14. Their function is to stir and mix the raw materials in the preparation tank 1 during rotation. The angle is changed to adapt to the mixing requirements of the raw materials at different stages. The power assembly includes a drive motor 6, which provides the main power for the rotation of the entire stirring assembly. The top of the drive motor 6 is fixedly connected to the bottom of the preparation tank 1. A rotating shaft 7 is fixedly connected to the output end of the drive motor 6. The rotating shaft 7 transmits the rotation of the drive motor 6, driving the fixed box 8 and the stirring blades 15 to rotate. The outer wall of the rotating shaft 7 passes through the bottom of the preparation tank 1, and the top of the rotating shaft 7 is fixedly connected to the bottom of the fixed box 8. The outer wall of the second drive motor 10 is fixedly connected to... Inside the rotating shaft 7, multiple sensors 9 are fixedly connected to the outer wall of the fixed box 8. The sensors 9 are used to detect the changes in liquid pressure on the stirring blade 15 during the stirring process. The sensors 9 are distributed in a circumferential shape. The control panel 2 is fixedly connected to the outer wall of the configuration tank 1. It is used by the operator to operate and control the entire configuration device, such as starting and stopping the drive motor 1 6 and drive motor 2 10, and controlling the opening and closing of the control valve 3. Multiple support legs 5 are fixedly connected to the bottom of the configuration tank 1. The support legs 5 are distributed in a circumferential shape. The discharge component includes the control valve 3. The control valve 3 is used to control whether the prepared coating liquid flows out and the flow rate. The side wall of the control valve 3 is fixedly connected to the bottom of the outer wall of the configuration tank 1. The other side wall of the control valve 3 is fixedly connected to the liquid outlet pipe 4.
[0035] Specifically, after the raw materials are injected into the preparation tank 1, the operator operates the corresponding button on the control panel 2 to start the drive motor 6. The output end of the drive motor 6 drives the rotating shaft 7 to rotate around its own axis. The rotation of the rotating shaft 7 also drives the fixed box 8 to rotate synchronously. The rotation of the fixed box 8 drives multiple stirring blades 15 on its outer wall to stir and mix the raw materials, causing the raw materials to tumble and mix in the preparation tank 1. As the coating liquid preparation process proceeds, the viscosity and other properties of the coating liquid will change, and the pressure exerted by the liquid on the stirring blades 15 will also vary. The sensor 9 on the outer wall of the fixed box 8 detects the pressure changes on the stirring blades 15 in real time. The sensing element inside the sensor 9 converts the pressure signal into an electrical signal, and then transmits the electrical signal to the control panel 2. After receiving the signal transmitted by the sensor 9, the control panel 2 sends a control signal to control the drive motor 10 to rotate. The output end of the drive motor 10 rotates around its own axis. The first bevel gear 11 rotates, meshing with the second bevel gear 12. When the first bevel gear 11 rotates, through meshing, the second bevel gear 12 rotates in a circle around its own axis inside the fixed box 8. The rotation of the second bevel gear 12 then drives the transmission rod 14 to rotate. When the transmission rod 14 rotates, the stirring blade 15 rotates synchronously. Driven by the transmission rod 14, the stirring blade 15 changes its tilt angle around the axis of the transmission rod 14 inside the mixing tank 1, so that the blade can always stir the raw materials at the optimal angle. This achieves efficient mixing at different stages. After mixing is completed, the operator operates the corresponding button on the control panel 2 to open the control valve 3. After receiving the control signal, the valve core inside the control valve 3 moves, opening the passage of the control valve 3. The mixed coating liquid is discharged from the mixing tank 1 through the control valve 3 along the outlet pipe 4 under the liquid pressure inside the mixing tank 1.
[0036] Reference Figure 4The feeding assembly includes a feed pipe 16, the bottom of which is fixedly connected to the top of the preparation tank 1 by welding. The feed pipe 16 is made of stainless steel, which has good corrosion resistance and a certain strength, and is used to transport the pre-mixed raw materials into the preparation tank 1. A mixing pipe 17 is fixedly connected to the top of the feed pipe 16 for preliminary mixing of various raw materials, preparing for subsequent deep mixing in the preparation tank 1. A feed pipe 18 is provided on one side of the top of the mixing pipe 17, and the bottom of the feed pipe 18 is fixedly connected to the outer wall of the mixing pipe 17. It is used to introduce various raw materials such as nylon particles, solvents, pigments, and additives into the mixing pipe 17, ensuring that the raw materials can accurately enter the mixing pipe 17 for preliminary mixing. A support frame 19 is provided at the bottom of the mixing pipe 17. The bottom of the support frame 19 is fixedly connected to the top of the configuration tank 1. The outer wall of the mixing tube 17 is slidably connected to the top of the support frame 19 to support the mixing tube 17 and keep it in a stable installation position. The side wall of the mixing tube 17 is fixedly connected to the drive motor 20, which provides power for the rotation of the screw conveyor 21. The output end of the drive motor 20 is fixedly connected to the screw conveyor 21, which is made of stainless steel. Through its own rotation, the screw conveyor 21 stirs and mixes the raw materials entering the mixing tube 17 to initially fuse the different raw materials. On the other hand, it conveys the mixed raw materials to the feed pipe 16 to ensure that the raw materials can smoothly enter the feed pipe 16 and then enter the configuration tank 1. The screw conveyor 21 is rotatably connected inside the mixing tube 17.
[0037] Specifically, when using the coating liquid preparation device, the operator first operates the relevant control buttons on the control panel 2 to start the feeding process. Based on the types and proportions of raw materials required for preparing the coating liquid, the operator injects nylon particles, solvents, pigments, additives, and other raw materials into the feed pipe 18. The various raw materials converge at the top of the mixing pipe 17. Subsequently, the output end of the drive motor 20 drives the screw conveyor 21 to rotate. During the rotation of the screw conveyor 21, its blades contact the raw materials inside the mixing pipe 17, pushing the raw materials to tumble and flow within the mixing pipe 17. The nylon particles, solvents, pigments, additives, and other raw materials... Under the stirring action of the blades of the screw conveyor 21, the raw materials are mixed together in the space inside the mixing tube 17, gradually achieving initial fusion. On the other hand, as the screw conveyor 21 rotates, its blades continuously push the raw materials along the inner wall of the mixing tube 17. Under the push of the blades of the screw conveyor 21, the raw materials fall into the feed pipe 16 and move linearly from the top of the feed pipe 16 to the bottom of the feed pipe 16, and finally inject into the interior of the preparation tank 1, thus achieving the initial mixing of the raw materials and laying the foundation for further mixing and preparation of the coating liquid in the preparation tank 1. This achieves the effect of initial mixing of the raw materials.
[0038] Working principle: When using this coating liquid preparation device, the operator first controls the equipment through the control panel 2, and injects raw materials such as nylon particles, solvent, pigment, and additives into the mixing pipe 17 through the feed pipe 18. Then, the drive motor 20 on the side wall of the mixing pipe 17 drives the screw conveyor 21 to rotate. The rotation of the screw conveyor 21 mixes the raw materials on one hand, and also conveys the raw materials towards the feed pipe 16 on the other hand. After the initial mixing, the raw materials fall into the feed pipe 16 and are injected into the interior of the preparation tank 1 under the action of gravity, thus achieving the effect of initial mixing of the raw materials.
[0039] After the raw materials are injected into the preparation tank 1, the operator starts the drive motor 6 through the control panel 2. The drive motor 6 drives the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 also drives the fixed box 8 to rotate synchronously. The rotation of the fixed box 8 drives the multiple stirring blades 15 on its outer wall to stir and mix the raw materials. As the viscosity and other properties of the coating liquid change, the pressure exerted by the liquid on the stirring blades 15 varies. The sensor 9 transmits the signal to the control panel 2, which controls the drive motor 10 to rotate, thereby driving the bevel gear 11 to rotate. The bevel gear 11 drives multiple bevel gears 12 to rotate, and then automatically adjusts the angle of the stirring blades 15 according to the pressure change, so that the blades can always stir the raw materials at the optimal angle. This achieves the effect of efficient mixing at different stages. After mixing is completed, the control panel 2 controls the control valve 3 to open, and the mixed coating liquid is discharged along the outlet pipe 4.
