Description

Technical Field

[0001] The present invention relates to a coating device and a coating preparation method, and in particular to a stealth coating mixing device and a preparation method for a ship signal light. Background Art

[0002] When mixing coatings, existing equipment only stirs through a stirring shaft, resulting in poor mixing effect. It cannot meet the mixing requirements of special materials such as stealth coatings and has poor practicality.

[0003] To this end, Chinese patent document CN108772018B discloses a coating mixing device for a high-barrier coating material coating device, which is provided with a first mixing drum and a second mixing drum, and the first mixing drum and the second mixing drum can perform circular motion, so that the coating to be mixed will continuously flow between the first mixing drum and the second mixing drum, so that during the mixing process, the coating is in a fluid state, which is conducive to the rapid mixing of multiple coatings; a gear ring is provided, which cooperates with the transmission gear to continuously drive the stirring blade to rotate when the first mixing drum and the second mixing drum perform circular motion. The stirring blade can stir the flowing coating and accelerate its mixing, which is conducive to improving work efficiency, has strong practicality, and ensures the high quality of the high-barrier coating material after coating.

[0004] However, to ensure the integrity and stability of the coating under various environmental conditions, stealth coatings typically require high bond strength. However, for high-viscosity, difficult-to-mix materials, the mixing effect achieved by flipping or using a large stirring rod cannot meet the desired requirements. The material cannot be smoothly and evenly dispersed during the stirring process, which can seriously affect the quality of the coating. In addition, the stirring mechanism of existing mixing devices is relatively complex to maintain and has poor practicality. Once the coating is mixed poorly, the coating surface will be uneven, the coating adhesion will be poor, the curing time will be prolonged, or the coating will be incompletely cured, which will seriously affect the performance of the stealth coating.

DETAILED DESCRIPTION

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1-Figure 3 : The ship signal light stealth coating mixing device provided by the present invention includes a mixing box 1, a stirring mechanism and a connecting mechanism 3. The stirring mechanism includes a stirring component 21 and a rotary drive component 22. The stirring component 21 is provided with at least three groups. The stirring component includes a rotating shaft 211 and a stirring rod 212. The stirring rod 212 is connected and installed on the rotating shaft 211 through the connecting mechanism 3. The rotary drive component 22 is used to drive the rotating shaft 211 to rotate.

[0034] The present invention achieves the function of simultaneously stirring at different locations within the mixing box 1 through the mixing box 1, stirring assembly 21, rotary drive assembly 22, and connecting mechanism 3. This not only greatly improves stirring efficiency and ensures that high-viscosity, difficult-to-mix materials reach a desired uniform state in a very short time, but also achieves a more detailed stirring effect through refined stirring action. In addition, the stirring assembly 21 adopts a multi-dimensional layout, which can simultaneously reach every corner and level within the mixing box, effectively avoiding the common problems of material accumulation and dead corners in traditional stirring equipment, and solving the problem that traditional stirring equipment has poor stirring effect on high-viscosity, difficult-to-mix materials. The mixing box 1 is provided with a controller for human-computer interaction, and the rotary drive component 22 is electrically connected to the controller; when performing the mixing process of the stealth coating, the organic solvent is placed in the mixing box 1, and then a signal is sent to the rotary drive component 22 through the controller. After receiving the signal, the rotary drive component 22 drives the rotating shaft 211 to rotate, and the rotating shaft 211 drives the stirring rod 212 to rotate through the connecting mechanism 3, and then the organic solution is stirred at different positions by multiple groups of stirring rods 212. The small-scale stirring makes the mixing of the organic solution more delicate and improves the uniformity of the stirring.

[0035] Reference Figure 2-Figure 4 : The connecting mechanism 3 includes a connecting frame 31 that is sleeved on the end of the rotating shaft 211, and at least two connecting rods 311 are provided on the connecting frame 31, and two clamping members 32 are movably provided on each connecting rod 311, and an opening and closing assembly 33 for controlling the opening and closing of the two clamping members 32 is provided on the connecting rod 311; in the working state, after the stirring rod 212 is tightly fitted with the connecting frame 31, when the opening and closing assembly 33 controls the clamping member 32 to be closed, the clamping member 32 is in contact with the stirring rod 212, and when the rotating shaft 211 rotates, the connecting frame 31 and the stirring rod 212 are driven to rotate synchronously.

[0036] The present invention achieves the function of connecting the rotating shaft 211 and the stirring rod 212 through the connecting frame 31, the clamping member 32, and the opening and closing assembly 33. By providing multiple stirring assemblies 21 for stirring in a small range, not only can the stirring uniformity be improved, but the relatively simple structure and modular design of multiple stirring assemblies 21 also make their maintenance costs relatively low. During maintenance, one or more stirring assemblies 21 can be individually inspected or replaced without affecting the normal operation of other units, greatly improving the convenience and efficiency of maintenance. At the same time, in order to further improve the maintenance portability of the stirring assembly 21, a connecting frame 31, a clamping member 32 and an opening and closing assembly 33 are designed to quickly disassemble and assemble the stirring rod 212. When disassembling the stirring rod 212, the two clamping members 32 are controlled to open by the opening and closing assembly 33, so that the two clamping members 32 are moved away from each other until the clamping member 32 is separated from the stirring rod 212, and the stirring rod 212 is removed. After the maintenance is completed, the stirring rod 212 is abutted against the connecting frame 31, and the rod of the stirring rod 212 is aligned with the connecting rod 311, and then the clamping member 32 is controlled to close by the opening and closing assembly 33, and then the stirring rod 212 is fixed to the connecting frame 31 by the abutment of the two clamping members 32 with the stirring rod 212, and then the rotating drive assembly 22 drives the rotating shaft 211 and the connecting frame 31 to rotate, and the connecting frame 31 drives the stirring rod 212 to rotate.

[0037] Reference Figure 4-Figure 6 When the cam 33 is in the closed position, the locking cam 330 is in the closed position, and the locking cam 331 is in the open position, so that the cam 330 can be locked.

[0038] The present invention realizes the function of controlling the opening and closing of the clamping member 32 through the first elastic member 331, the inclined pressure block 332, the fixing assembly 41 and the control assembly 42. Through the setting of the inclined pressure block 332, the clamping member 32 can be automatically in the open state when it moves to the specified position, and its movement is restricted by the fixing assembly 41, so that the clamping member 32 is kept in the open state, thereby facilitating the operator to install the stirring rod 212. When disassembling the stirring rod 212, the operator overcomes the elastic force of the first elastic member 331 and manually moves the clamping member 32, moves the clamping member 32 to the inclined pressure block 332, and squeezes the inclined pressure block 332 to open the clamping member 32, and when the clamping member 32 moves to the inclined pressure block 332, the fixing assembly 41 automatically restricts the clamping member 32 from resetting under the elastic force of the first elastic member 331. After completing the maintenance, the operator installs the stirring rod 212 on the connecting frame 31, and then releases the movement restriction of the clamping member 32 by the fixing component 41 through the control component 42. The clamping member 32 extends under the elastic force of the first elastic member 331, thereby separating the clamping member 32 from the inclined pressure block 332. After separation, the clamping member 32 loses the squeezing effect of the inclined pressure block 332, and then abuts against the stirring rod 212 again, fixing the stirring rod 212 on the connecting frame 31.

[0039] Reference Figure 4 、 Figure 5 and Figure 7 : The clamping member 32 includes a slider 321, a clamping block 322 and a second elastic member 323. A sliding groove 3111 is provided on the connecting rod 311. The slider 321 is slidably installed on the sliding groove 3111, and a guide rod 3211 is provided on the slider 321. The clamping block 322 slides with the guide rod 3211, and the two ends of the second elastic member 323 are respectively connected to the clamping block 322 and the slider 321.

[0040] The present invention realizes the elastic expansion and contraction function of the clamping block through the slider 321, the guide rod 3211, the clamping block 322 and the second elastic member 323. The two ends of the first elastic member 331 are respectively connected to the slider 321 and the connecting rod 311; when the clamping block moves toward the oblique pressure block 332, the clamping block 322 is squeezed by the oblique pressure block 332, thereby overcoming the elastic force of the second elastic member 323 to drive the clamping block 322 to move in the direction away from the slider 321, so that the clamping member 32 opens, canceling the restriction on the stirring rod 212, and at the same time, the fixed component 41 restricts the movement of the slider 321 under the elastic force of the first elastic member 331. When the control component 42 releases the restriction of the fixed component 41 on the movement of the slider 321, the slider 321 drives the clamping block 322 to move through the guide rod 3211, thereby separating the clamping block 322 from the oblique pressure block 332. After the clamping block 322 loses its squeezing effect, it resets under the elastic force of the second elastic member 323 and is in a closed state again.

[0041] Reference Figure 6 : A limit block 312 is provided on the connecting rod 311 for limiting the moving range of the clamping member 32.

[0042] The present invention realizes the function of limiting the movement range of the slider 321 through the limit block 312. The two ends of the first elastic member 331 are respectively connected to the limit block 312 and the slider 321, and the first elastic member 331 is preferably a nitrogen spring; through the setting of the limit block 312, it is possible to avoid the situation where the slider 321 moves excessively and separates from the slide groove 3111. If there is no restriction mechanism, the slider 321 may exceed its normal movement range due to improper operation or the influence of external factors, thereby causing damage to the equipment, reduced work efficiency and even the occurrence of safety accidents. Specifically, the main function of the limit block 312 is to accurately limit the movement range of the slider 321, thereby effectively preventing the slider 321 from accidentally separating from the slide groove 3111 due to excessive movement.

[0043] Reference Figure 6-Figure 8 : The fixing assembly 41 includes a locking block 411 and a third elastic member 412. The locking block 411 is slidably installed on the connecting rod 311. The two ends of the third elastic member 412 are respectively connected to the locking block 411 and the connecting rod 311. A locking groove 413 that cooperates with the locking block 411 is provided on the slider 321.

[0044] The present invention realizes the function of limiting the movement of the slider 321 when the slider 321 moves to the oblique pressing block 332 through the locking block 411 , the third elastic member 412 and the locking groove 413 . The locking block 411 is provided with an inclined surface. When the operator pushes the clamping member 32 toward the oblique pressure block 332, when the clamping block 322 contacts the inclined surface of the oblique pressure block 332, they are squeezed away from each other by the oblique pressure block 332. After the slider 321 contacts the locking block 411, it squeezes the inclined surface of the locking block 411, thereby overcoming the elastic force of the third elastic member 412 and pushing the locking block 411 to slide in the direction away from the slider 321. When the slider 321 slides to the locking block 411, the locking groove 413 on the slider 321 is aligned with the locking block 411, and the locking block 411 is inserted into the locking groove 413 under the elastic force of the third elastic member 412, and then the movement of the slider 321 is limited by the cooperation between the locking block 411 and the locking groove 413.

[0045] Reference Figure 5 and Figure 9: The auxiliary control mechanism 4 also includes a transmission assembly 43, the transmission assembly 43 includes a pressure plate 431 and a fourth elastic member 432, the pressure plate 431 is slidably installed on the connecting rod 311, the two ends of the fourth elastic member 432 are respectively connected to the pressure plate 431 and the connecting rod 311, and the pressure plate 431 is transmission-connected to the control assembly 42; in the working state, when the stirring rod 212 overcomes the elastic force of the fourth elastic member 432 to press the pressure plate 431 downward, the transmission assembly 43 drives the control assembly 42, and releases the movement restriction of the clamping member 32 by the fixing assembly 41 through the control assembly 42.

[0046] The present invention realizes the function of quickly installing the stirring rod 212 through the pressure plate 431 and the fourth elastic member 432. During the process of disassembling the stirring rod 212, the slider 321 cooperates with the fixing assembly 41, and the movement of the slider 321 is limited by the fixing assembly 41, so as to maintain the opening and closing state of the clamping member 32. Then the operator presses the maintained stirring rod 212 against the connecting rod 311, aligns the rod body of the stirring rod 212 with the connecting rod 311, and presses the stirring rod 212 downward. The stirring rod 212 overcomes the elastic force of the fourth elastic member 432 to squeeze the pressure plate 431. The pressure plate 431 moves downward while driving the control assembly 42. The control assembly 42 releases the movement restriction of the slider 321 by the fixing assembly 41, and then the slider 321 is pushed back to its original position by the elastic force of the first elastic member 331, so that the clamping block 322 is separated from the inclined pressure block 332, and the stirring rod 212 is automatically restricted on the connecting rod 311.

[0047] Reference Figure 6 and Figure 8 : The control component 42 includes an extension seat 421 and a connecting seat 422, the extension seat 421 is connected to the locking block 411, the connecting seat 422 is connected to the pressure plate 431, and a pressure rod 4221 is provided on the connecting seat 422, and a pressure groove 4211 is provided on the extension seat 421 to cooperate with the pressure rod 4221. When the pressure plate 431 drives the connecting seat 422 and the pressure rod 4221 to move downward, the pressure rod 4221 squeezes the pressure groove 4211 on the extension seat 421, pushing the extension seat 421 and the locking block 411 to move away from the locking groove 413.

[0048] The present invention realizes the function of controlling the movement of the locking block 411 through the extension seat 421 and the connecting seat 422. When installing the stirring rod 212, the stirring rod 212 is pressed down, and the stirring rod 212 overcomes the elastic force of the fourth elastic member 432 to squeeze the pressure plate 431. When the pressure plate 431 moves downward, it drives the connecting seat 422 and the pressure rod 4221 to move. The pressure rod 4221 squeezes the pressure groove 4211 on the extension seat 421, and then drives the extension seat 421 and the locking block 411 to move away from the locking groove 413 through the squeezing action, releasing the movement restriction of the slider 321 by the fixing assembly 41. Then, the slider 321 is pushed back to its original position by the elastic force of the first elastic member 331, so that the clamping block 322 is separated from the oblique pressure block 332, and the stirring rod 212 is automatically restricted to the connecting rod 311.

[0049] Reference Figure 2 、 Figure 10 and Figure 11 : A mounting plate 11 is movably provided on the mixing box 1, and a support rod 111 is provided on the mounting plate 11. The support rod 111 slides with the mounting plate 11, and a rotating shaft 211 is rotatably provided on the support rod 111. The rotation drive assembly 22 is installed on the mounting plate 11, and a synchronous transmission assembly 23 that synchronously connects multiple rotating shafts 211 is installed on the mounting plate 11.

[0050] The present invention realizes the function of supporting the rotating shaft 211 and the stirring rod 212 through the mounting plate 11 and the support rod 111, and achieves the effect of driving multiple rotating shafts 211 to rotate synchronously through the rotating drive assembly 22. At the same time, the effect of controlling the lifting and lowering of the stirring assembly 21 is achieved through the mounting plate 11. During stirring, in order to reduce the stirring dead angle, a mounting plate 11 is specially provided. The lifting and lowering of the stirring assembly 21 is controlled by controlling the lifting and lowering of the mounting plate 11. The mounting plate 11 is automatically lifted and lowered by the drive of the lifting assembly. The lifting assembly is preferably a hydraulic lifting rod or an electric push rod. The lifting assembly is not shown in the figure. When driving the stirring assembly 21, the rotating drive assembly 22 drives one of the rotating shafts 211 to rotate, and the rotating shaft 211 drives the remaining rotating shafts 211 to rotate synchronously through the synchronous transmission assembly 23.

[0051] Reference Figure 10 and Figure 11 : A first rotating gear 231 is sleeved on each rotating shaft 211, and a second rotating gear 232 is rotatably mounted on the mounting plate 11. The second rotating gear 232 is meshed and connected with multiple first rotating gears 231 at the same time.

[0052] The present invention realizes the function of transmission connection of multiple rotating shafts 211 through the first rotating gear 231 and the second rotating gear 232. The rotating drive assembly 22 includes a rotating driver 221 and a bevel gear 222. The rotating driver 221 is mounted on the mounting plate 11. Two bevel gears 222 are provided. The two bevel gears 222 are respectively connected to the driving end of the rotating driver 221 and one of the rotating shafts 211. When the rotating driver 221 is started, the bevel gear 222 drives the rotating shaft 211 to rotate. The rotating shaft 211 drives the first rotating gear 231 to rotate. The first rotating gear 231 drives the second rotating gear 232 meshed with it to rotate. The second rotating gear 232 then drives the remaining first rotating gears 231 to rotate synchronously, thereby achieving the effect of simultaneously driving multiple rotating shafts 211 and the stirring assembly 21.

[0053] The present invention also provides a method for preparing a stealth coating for a ship signal light using the above-mentioned mixing device, comprising the following steps: S1. Preliminarily mixing the raw materials in a specified proportion to form an organic solvent, and placing the organic solvent for preparing the stealth coating into the mixing device; S2. Starting the mixing device, heating and stirring the solvent, and obtaining a structural radar absorbing coating after uniform mixing; S3. Grinding and polishing the substrate to be coated with the coating, and then sequentially coating the substrate with an adhesive, a structural radar absorbing coating, and a curing agent. After curing, a composite stealth coating is formed on the surface of the substrate.

[0054] Preferably, step S1 involves preliminarily mixing, by mass, 10%-25% aluminum powder, 5%-20% Ti3C2Tx, 18%-29% binder, 1%-2% orienting agent, and 40%-50% solvent to form an organic solvent. The adhesive can be chlorinated polystyrene, and the curing agent is preferably an isocyanate curing agent.
