Description

Technical Field

[0001] The invention belongs to the technical field of paint smoothing, and in particular relates to a constant-force paint smoothing device with floating function and a paint construction method. Background Art

[0002] The paint smoothing process is a key link in architectural decoration and industrial coating, and its quality directly affects the coating uniformity, adhesion strength and surface finish. However, existing smoothing equipment has significant technical defects in tool adaptability and pressure control accuracy, resulting in low construction efficiency and high rework rate.

[0003] First, the flatness of the base surface at the construction site generally has an error of ±5mm. Traditional leveling equipment relies on the operator's experience to manually adjust the pressure, but the fluctuation range of manual pressure is as high as 30-80N (the standard requirement is 50±5N). When the pressure is insufficient, the paint has poor leveling properties, resulting in defects such as fish eyes and orange peels; overloaded pressure squeezes out base impurities or scratches the bottom layer. Although existing electric leveling machines can set pressure values, they cannot dynamically compensate for base surface fluctuations. When encountering local protrusions, the pressure peak can reach 120N, resulting in excessive extrusion of paint; and the pressure in the concave area drops sharply to 20N, resulting in hollow paving.

[0004] Secondly, modern coating projects need to deal with a variety of material systems such as epoxy flooring, artistic coatings, and waterproof slurries. The parameters of their optimal smoothing tools vary significantly: epoxy coatings require tungsten steel scrapers with a hardness of HRC55 or above to resist quartz sand wear, while artistic coatings require flexible silicone scrapers to achieve texture shaping. Traditional equipment scrapers are mostly fixed with bolt pressure plates. A single replacement requires the removal of 6-8 bolts, which takes more than 15 minutes. Frequent disassembly and assembly can easily lead to the expansion of the positioning holes, causing the scraper inclination angle to deviate. Summary of the invention

DETAILED DESCRIPTION

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0023] Example 1 Please refer to the attached Figures 1 to 4 and Figures 9 and 10 As shown, it is the first embodiment of the present invention, which provides a constant force paint leveling device with floating, including: The main body assembly 10 includes three groups of hydraulic rods 13, and the upper ends of the three groups of hydraulic rods 13 are all provided with universal balls 16; The rotating assembly 20 includes four groups of limit sleeves 26. The inner cavities of the four groups of limit sleeves 26 are all provided with sliding bearings 27. The inner rings of the sliding bearings 27 are fixedly connected with fixed seats 28. A top plate assembly 30, the top plate assembly 30 includes a mounting plate 31, the mounting plate 31 is fixedly connected to the upper end of the fixing seat 28, and the lower end of the mounting plate 31 is contact-connected to the upper ends of the three sets of universal balls 16; A quick release assembly 40, the quick release assembly 40 includes a scraper 42, and a magnetic slider 44 is provided at the lower end of the scraper 42; The three sets of universal balls 16 drive the mounting plate 31 to tilt through the operation of the hydraulic rod 13, and the fixing seat 28 slides in the limiting sleeve 26 through the sliding bearing 27 to provide a floating range for the mounting plate 31; The magnetic slider 44 is used to quickly fix or unlock the scraper 42 .

[0024] It should be noted that, when in use, the device needs to be connected to a set of external control components (not shown in the figure) to facilitate the control of the operation of the hydraulic rod 13 and various electrical components in the device.

[0025] In this embodiment, before performing the smoothing operation, the scraper 42 is placed on the upper end of the mounting plate 31, and the quick-release assembly 40 adsorbs the magnetic slider 44 to pop out and fix the scraper 42. Then, the three groups of hydraulic rods 13 push the universal ball 16 to rise, adjust the inclination angle of the mounting plate 31 and the scraper 42, and then the rotating assembly 20 drives the mounting plate 31 and the scraper 42 to perform a rotating smoothing operation. If the wall surface is undulating, the mounting plate 31 will drive the fixed seat 28 and the sliding bearing 27 to move in the limit sleeve 26, so that the mounting plate 31 can float and adapt to the wall surface to ensure the stability of smoothing.

[0026] Next, please refer to Figure 1 to Figure 2 and Figure 5 to Figure 6The main assembly 10 further includes a bottom plate 11, and three groups of mounting pipes 12 are fixedly mounted on the upper end of the bottom plate 11, and three groups of hydraulic rods 13 are respectively fixedly mounted in the inner cavities of the three groups of mounting pipes 12; The main assembly 10 further includes three groups of lifting seats 14, which are respectively fixedly mounted on the upper ends of the three groups of hydraulic rods 13, and the inner cavities of the lifting seats 14 are fixedly mounted with universal ball seats 15, and the universal balls 16 are movably sleeved in the universal ball seats 15, and the lower ends of the inner cavities of the universal ball seats 15 are fixedly mounted with pressure sensors 17, and the probes of the pressure sensors 17 extend out of the universal ball seats 15 and contact and connect with the lower ends of the universal balls 16; The probe of the pressure sensor 17 is a semicircular structure, and the lower end of the universal ball 16 and the probe of the pressure sensor 17 are adapted to each other.

[0027] It should be noted that there is a connection relationship between the pressure sensor 17 and the control component connected to the device. The original intention of this design is to enable the control component to monitor the working status of the pressure sensor 17 in real time. Once an abnormality is detected in the pressure sensor 17, the control component will immediately start and drive the hydraulic rod 13 connected to it to make corresponding adjustments. Such a mechanism ensures that during the leveling operation, the pressure between the mounting plate 31 and the universal ball 16 can always be maintained within the set appropriate pressure threshold range, thereby ensuring the accuracy of the operation and the stable operation of the equipment.

[0028] In addition, in order to further improve the durability and reliability of the device, protective covers are specially designed on the upper outer rings of the bottom plate 11 and the mounting tube 12. The function of these protective covers is to prevent foreign impurities such as dust and debris from entering the device during the leveling operation and contacting sensitive electronic components. In this way, equipment failures caused by the intrusion of impurities can be effectively avoided, thereby extending the service life of the device and ensuring its stable performance in various working environments.

[0029] In this embodiment, before the smoothing operation begins, the three groups of hydraulic rods 13 will respectively drive the lifting seat 14 to rise or fall. The lifting seat 14 then drives the universal ball 16 in the universal ball seat 15 to rise and fall. Through these three groups of universal balls 16 of different heights, the inclination angle of the mounting plate 31 can be finely adjusted to meet the specific needs of different wall surfaces. At the same time, the pressure sensor 17 will monitor the pressure between the universal ball 16 and the mounting plate 31 in real time to ensure that the pressure value is always maintained within the preset threshold range. When the wall surface is uneven, if the pressure between the mounting plate 31 and the universal ball 16 exceeds the set threshold, the system will automatically control the corresponding hydraulic rod 13 to contract or extend to ensure that the pressure between the mounting plate 31 and the universal ball 16 is always maintained within the preset threshold range, and in the state of floating adjustment, the universal ball 16 always maintains a constant force output to the mounting plate 31.

[0030] Next, please refer to Figures 1 to 5 The rotating assembly 20 further includes a motor 21, which is fixedly mounted on the lower end of the bottom plate 11. The output shaft of the motor 21 passes through the bottom plate 11 and is disposed on the upper end of the bottom plate 11. The upper end of the output shaft of the motor 21 is fixedly connected with a gear 22. The middle part of the upper end of the bottom plate 11 is rotatably connected with a rotating shaft 23 through a ball bearing. A gear ring 24 is fixedly mounted on the outer ring of the middle part of the rotating shaft 23. The outer ring of the gear ring 24 meshes with the outer ring of the gear 22. The rotating assembly 20 further includes a rotating disk 25, which is fixedly mounted on the upper end of the rotating shaft 23, and four sets of limit sleeves 26 are evenly distributed and fixedly mounted on the upper end of the rotating disk 25. A support rod 29 is movably sleeved on the upper end of the rotating disk 25, and the support rod 29 is movably sleeved on the middle inner ring of the mounting disk 31, and the lower end of the support rod 29 penetrates the rotating shaft 23 and is fixedly connected to the bottom plate 11; There is a gap between the limit sleeve 26 and the sliding bearing 27, and the width of the gap is preferably 3mm to 5mm, so that the sliding bearing 27 can be offset to a certain extent through the gap, thereby causing the mounting plate 31 to be offset, and the offset angle of the mounting plate 31 is controlled to be about 5 degrees ± 1 degree, so that the putty can be adaptively fitted to the wall during paint construction, avoiding interference between the putty plate and the wall during operation.

[0031] It should be noted that the sliding bearing 27 only extends into the inner space of the limiting sleeve 26, and its outer side and end are not in contact with the limiting sleeve 26. This structure allows the limiting sleeve 26 to contact the sliding bearing 27 when rotating, and can guide the sliding bearing 27 to rotate with the limiting sleeve 26. Such a design ensures that the four sets of sliding bearings 27 and the limiting sleeve 26 can achieve flexible floating adjustment, thereby avoiding the adverse effects of the limiting problem on the movement of the sliding bearing 27 and ensuring its smooth movement performance.

[0032] In this embodiment, when the smoothing work is in progress, the motor 21 drives the gear 22 and the gear ring 24 to rotate, thereby driving the rotating shaft 23 and the rotating disk 25 to rotate, and the limiting sleeve 26 also rotates synchronously, thereby driving the sliding bearing 27 and the fixed seat 28 to rotate. Since the upper end of the fixed seat 28 is fixedly connected to the mounting plate 31, the mounting plate 31 and the scraper 42 also rotate together to perform the smoothing operation. In the process of rotating smoothing, if the wall surface is uneven, the mounting plate 31 will drive the fixed seat 28 and the sliding bearing 27 to slide in the limiting sleeve 26, thereby causing the mounting plate 31 to produce a certain degree of tilt and float. This tilt adjustment enables the mounting plate 31 to float and adapt to the wall surface, avoiding the problem of excessive local pressure caused by the undulation of the wall surface, thereby ensuring the stability and continuity of the smoothing work, and enabling the equipment to adapt to the smoothing needs of different wall surfaces.

[0033] Next, please refer to Figure 5 and Figures 7 and 8 The top plate assembly 30 also includes an additional block 32, which is movably sleeved in the middle of the upper end of the mounting plate 31, and a laser spotlight 33 is fixedly installed in the inner cavity of the additional block 32, and the irradiation end of the laser spotlight 33 is arranged on the outside of the additional block 32, and a bearing seat 34 is fixedly connected to the middle of the lower end of the mounting plate 31, and an eccentric bearing 35 is fixedly installed in the inner cavity of the bearing seat 34, and the inner ring part of the eccentric bearing 35 is fixedly connected to the upper outer ring of the support rod 29.

[0034] It should be noted that the portion where the upper end of the support rod 29 is connected to the eccentric bearing 35 is designed to be a hemispherical structure, the main purpose of which is to enable the mounting plate 31 to be tilted around the upper end of the support rod 29 through the eccentric bearing 35. This design makes it more convenient and flexible to adjust the tilt angle and perform floating adjustment; In addition, the upper end of the support rod 29 is fixedly connected to the mounting block 32. Wires are arranged inside the support rod 29, and these wires are connected to the mains, thereby ensuring that the laser spotlight 33 in the mounting block 32 can obtain a stable power supply and ensure its normal operation; A rubber scraper (such as Figure 6 As shown). The scraper blade is used to effectively clean the surface of the laser spotlight 33 when the mounting plate 31 and the scraper 42 are rotating (the fixed support rod 29 and the mounting block 32 are in relative motion with the mounting plate 31). This design ensures that the surface of the laser spotlight 33 will not be affected by objects blocking it during the leveling operation, thereby avoiding possible errors during the leveling process.

[0035] In this embodiment, before leveling, the mounting plate 31 is placed close to the wall, and the laser spotlight 33 emits laser to assist the worker in leveling, thereby improving the stability and efficiency of the leveling operation. When the wall surface is undulating, the mounting plate 31 can be tilted through the eccentric bearing 35, thereby achieving adaptive fit between the mounting plate 31 and the wall surface, thereby further improving the accuracy and efficiency of leveling. At the same time, the presence of the rubber scraper can also effectively prevent the surface of the laser spotlight 33 from being contaminated by dust or paint, ensuring the clarity of the laser, making the leveling work more accurate and reliable.

[0036] Please refer again Figures 9 to 14 The quick-release assembly 40 also includes three groups of connecting blocks 41, which are all contact-connected to the upper end of the mounting plate 31, and the scrapers 42 are fixedly mounted on the connecting blocks 41. The lower end of the connecting block 41 is fixedly connected to five groups of plug rods 43, which are all movably plugged into the inner cavity of the mounting plate 31, and the lower end of the plug rod 43 extends out of the mounting plate 31. The magnetic slider 44 is slidably connected to the inner cavity of the part of the plug rod 43 extending out of the mounting plate 31, and the end of the magnetic slider 44 away from the inner cavity of the plug rod 43 is fixedly connected to the magnetic suction block 45. A limiting tube 46 is fixedly installed at the lower end of the mounting plate 31, and a moving plate 47 is slidably connected to the inner cavity of the limiting tube 46. Five groups of push blocks 48 are fixedly connected to the side of the moving plate 47 close to the magnetic slider 44. One end of the five groups of push blocks 48 close to the magnetic slider 44 are all in contact with and connected to the magnetic suction block 45, and the five groups of push blocks 48 and the five groups of magnetic sliders 44 are adapted to each other. Three groups of springs 49 are fixedly connected to the side of the moving plate 47 close to the magnetic slider 44, and the other ends of the three groups of springs 49 are fixedly connected to the inner cavity of the limiting tube 46.

[0037] It should be noted that in the area where the push block 48 contacts the magnetic attraction block 45, a matching magnetic component is specially designed to ensure that sufficient magnetic interaction can be generated between the two. The upper end of the magnetic slider 44 is designed to have an inclined groove structure, and the length of the inclined groove is deliberately designed to be shorter than the length of the magnetic slider 44 extending from the insertion rod 43. The purpose of this design is to ensure that even if the push block 48 does not completely push the magnetic slider 44 into the insertion rod 43, when the insertion rod 43 moves upward, the inclined groove at the upper end of the magnetic slider 44 can effectively retract the magnetic slider 44 into the insertion rod 43 under the force of the slope. In addition, the width of the inclined groove is designed to be narrow to avoid affecting the stability of the magnetic slider 44 fixing the insertion rod 43 after the extension due to the inclined groove being too wide, thereby ensuring the stability and reliability of the entire device.

[0038] In this embodiment, during the installation process, a suitable scraper 42 and connecting block 41 are selected, and the plug rod 43 is inserted into the installation disk 31 and the limit tube 46. At this time, the magnetic block 45 on the magnetic slider 44 is attracted by the magnetic component on the push block 48, so that the magnetic slider 44 extends out of the plug rod 43, thereby fixing the plug rod 43. When the scraper 42 needs to be removed, it is only necessary to push the moving plate 47 to drive the push block 48 to move, so that the push block 48 pushes the magnetic block 45 and the magnetic slider 44 back into the plug rod 43. At this time, the plug rod 43 loses its fixation, and the connecting block 41 can be pulled up to remove the plug rod 43 and the connecting block 41 from the installation disk 31 to achieve quick disassembly. The design of this quick-release assembly 40 not only simplifies the replacement process of the scraper 42 and improves work efficiency, but also ensures the stability of the scraper 42 during installation, and avoids the deterioration of the leveling quality caused by the loosening of the scraper 42 during the operation. In addition, the design of the magnetic slider 44 and the push block 48 makes the disassembly and installation process smoother, reduces damage to the equipment caused by improper operation, and further improves the durability and reliability of the equipment.

[0039] Example 2 A coating construction method, suitable for the above-mentioned floating constant force coating leveling equipment to carry out coating construction, comprising: S1: Leveling: Install a suitable scraper 42 on the mounting plate 31, then move the mounting block 32 close to the wall and perform leveling with the laser spotlight 33; S2: Adjustment: The three groups of hydraulic rods 13 respectively push the universal balls 16 to rise, and use the universal balls 16 at different heights to adjust the inclination angles of the mounting plate 31 and the scraper 42, and provide stability for the tilted mounting plate 31 through the cooperation of the eccentric bearing 35 and multiple groups of sliding bearings 27 and the limiting sleeve 26; S3: Operation: The motor 21 drives the gear 22 and the gear ring 24 to rotate, and then drives the rotating shaft 23 and the rotating disk 25 to rotate, and drives the limiting sleeve 26 and the fixing seat 28 to rotate, so that the mounting disk 31 and the scraper 42 rotate to smooth the putty; S4: Floating adaptation: During the smoothing process, once the wall rises and falls, the mounting plate 31 will drive the fixing seat 28 and the sliding bearing 27 to slide in the limiting sleeve 26, so that the mounting plate 31 can float and adapt to the rise and fall of the wall, avoiding excessive local pressure that may hinder the smoothing work.

[0040] In this embodiment, when performing the floating adaptation in S4, when the mounting plate 31 encounters the ups and downs of the wall and is subjected to the squeezing force, the adjustment step in S2 will be executed, and the hydraulic rod 13 at the corresponding position will shrink or extend, thereby controlling the mounting plate 31 to perform floating adaptation, and during the adaptation process, the universal ball 16 is always attached to the lower end of the mounting plate 31, maintaining a constant force output to the mounting plate 31.

[0041] The working principle of the present invention is as follows: during the installation process, a suitable scraper 42 and a connecting block 41 are selected, and the plug rod 43 is inserted into the installation disk 31 and the limiting tube 46. At this time, the magnetic block 45 on the magnetic slider 44 is attracted by the magnetic component on the push block 48, so that the magnetic slider 44 extends out of the plug rod 43, thereby fixing the plug rod 43. Then, the three groups of hydraulic rods 13 will respectively drive the lifting seat 14 to rise or fall. The lifting seat 14 then drives the universal ball 16 in the universal ball seat 15 to rise and fall. Through these three groups of universal balls 16 of different heights, the inclination angle of the installation disk 31 can be finely adjusted. Then, the motor 21 drives the gear 22 and the gear ring 24 to rotate, thereby driving the rotating shaft 23 and the rotating disk 25 to rotate, and the limiting sleeve 26 also rotates synchronously, thereby driving the sliding bearing 27 and the fixed seat 28 to rotate. Since the upper end of the fixed seat 28 is fixedly connected to the installation disk 31, the installation disk 31 and the scraper 42 also rotate together to perform the leveling operation. During the process of rotation and smoothing, if the wall surface is uneven, the mounting plate 31 will be tilted due to the adjustment of the hydraulic rod 13, thereby driving the fixed seat 28 and the sliding bearing 27 to slide in the limiting sleeve 26, thereby causing the mounting plate 31 to produce a certain degree of tilt and floating. This tilt adjustment enables the mounting plate 31 to float and adapt to the wall surface.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
