Description

Technical Field

[0001] The utility model relates to the technical field of coating film coating, and specifically to a waterproof coating film coating device. Background Art

[0002] Waterproof coating is a coating used for building waterproofing. It can form a continuous waterproof film in a humid or dry environment, effectively preventing moisture penetration and protecting buildings from water damage. It is a viscous liquid polymer synthetic material with no fixed shape at room temperature, including emulsions and coatings. After coating, a tough waterproof film is formed on the base surface through the volatilization of solvents, volatilization of water or reaction curing. It is generally used in balconies, toilets, bathrooms, kitchens, swimming pools, roofs, underground, exterior walls and other places that require waterproofing.

[0003] Before coating, it is necessary to use a stirring device to prepare the waterproof coating, and then use a coating device to coat the coating after the preparation is completed. If the coating thickness is uneven, too thick or too thin, it will affect the quality of the waterproof coating. Although the existing coating device can complete the coating work normally, there are still the following problems: Since the two ends of the scraper are fixed to the bracket by bolts, when adjusting the coating thickness, it is necessary to manually adjust the bolts at both ends of the scraper to adjust the height of the scraper, which makes it impossible to conveniently adjust the thickness of the coating each time. Utility Model Content

[0004] The utility model provides a waterproof coating film coating device, which solves the problem that the existing coating film coating device in the related art cannot conveniently adjust the coating film thickness each time.

[0005] The technical solution of the utility model is as follows:

[0006] Waterproof coating film coating device, comprising:

[0007] Frame;

[0008] A support plate, the support plate is movably arranged relative to the frame;

[0009] A scraper, wherein the scraper is swingably arranged relative to the support plate, the scraper moves following the support plate, the scraper has a scraping portion, the shortest distance from the scraping portion to the support plate is the coating length, and after the scraper swings, the coating length increases or decreases;

[0010] A wheel portion is rotatably arranged on the support plate, and the wheel portion is fixedly connected to the scraper.

[0011] As a further technical solution, the scraper has a rotating shaft, and the rotating shaft is fixedly arranged at the center position of the wheel part.

[0012] As a further technical solution, the support plate has a groove, the scraper is swingably arranged in the groove, the bottom of the groove has an arc surface, the scraper abuts against the arc surface, and the scraping part is exposed from the groove.

[0013] As a further technical solution, the wheel portion is rotatably arranged in the groove, there are two wheel portions, the two wheel portions are respectively located at both ends of the scraper, and the length of the groove is equal to the sum of the length of the scraper and the width of the two wheel portions.

[0014] As a further technical solution, the support plate is rectangular, there are three support plates, and the three support plates are hingedly connected in sequence along the length direction of the support plate. The support plate hinge axis is perpendicular to the scraper swing axis, and the support plate hinge axis is parallel to the support plate movement direction.

[0015] As a further technical solution, the wheel portion has an elastic protrusion on one side away from the scraper, and the elastic protrusions are multiple and arranged circumferentially. After the wheel portion rotates, the elastic protrusions press against or release the inner wall of the groove.

[0016] As a further technical solution, there are a plurality of grooves, and the plurality of grooves are arranged at intervals along the moving direction of the support plate.

[0017] As a further technical solution, it also includes:

[0018] A screw rod is rotatably arranged on the frame body, the axial direction of the screw rod is parallel to the moving direction of the support plate, and the support plate is threadedly connected to the screw rod.

[0019] The working principle and beneficial effects of the utility model are:

[0020] In the utility model, after the waterproof coating is prepared, the traditional coating device usually adopts the form of a fixed-structure scraper to apply the coating, and the coating operation is completed by moving the scraper. However, various situations are inevitable in on-site construction, and different requirements are placed on the coating thickness, such as thicker, thinner or tilted. The traditional fixed structure cannot adapt well to the above-mentioned various situations, and cumbersome scraper adjustment operations are required, such as manually adjusting the bolts at both ends of the scraper to adjust the height of the scraper. Therefore, in order to solve the above-mentioned problems and adapt to more comprehensive coating scenarios, a waterproof coating coating device is designed.

[0021] Working principle: the frame basically keeps its position unchanged when working, and the support plate drives the scraper to move, and performs coating operations on walls and other places. During operation, it is mainly realized by the scraper part on the scraper; the scraper position is adjusted, and the traditional bolt fixing form is changed to an adjustable swing form, so as to achieve the shortest distance from the scraper to the support plate after the swing, and the coating length can be increased or decreased. In other words, the position of the frame and the support plate remains unchanged, the scraper swings, and the contact area between the scraper and the waterproof coating changes, so as to accurately meet the needs of different coating thicknesses and greatly improve flexibility.

[0022] Further consideration is that directly adjusting the swing angle of the scraper may not be precise enough, and it is inconvenient for workers to directly contact the scraper part, so the power required for the scraper to swing is provided by rotating the wheel part set on the support plate. Precise scales can be added around the rotating wheel part. As long as the wheel part rotates to the corresponding scale position, it means that the scraper part has been adjusted to the required coating position.

[0023] Scenarios of different horizontal thicknesses have been adapted, but if faced with an inclination requirement, that is, the coating thickness is constantly changing, since it is not convenient to change the linear horizontal movement of the support plate to make it level with the required inclination angle, there are the following two ways to solve the above problem: The first way is to use a wheel that actively drives the scraper to swing and adjust, so that it is provided on the support plate and through a power source such as a motor located on one side of the wheel, so that the swing angle of the scraper is constantly changing during the coating process, that is, during the entire coating process, the thickness of the waterproof coating scraped by the scraper is constantly increasing or decreasing to meet the requirements.

[0024] The second method, as shown in Figure 3, is to set a wheel body at the bottom of the frame body, which can simultaneously drive the frame body to move and adjust the entire inclination angle of the frame body. The rotation of the wheel body can drive the frame body to move to the working position. Since the waterproof coating coating device itself is heavy, even if there is a wheel body at the bottom, it will not affect the stability of the coating work. It is only necessary to ensure that the wheel body does not rotate during operation, and by adjusting the position of the wheel body, that is, two symmetrical support blocks are movably set on the frame body, and the wheel body is rotatably set between the two symmetrical support blocks. After the support block moves away from or close to the ground, the moving angle of the support plate can be adjusted, and then, under the premise of fixing the swing angle of the scraper, the waterproof coating can be coated under the inclination requirement.

[0025] In summary, the innovative design of this waterproof coating coating device significantly improves the accuracy and efficiency of the coating process and reduces costs through the combination of precise control, dynamic adaptability, efficient operation, stability and easy maintenance. It is suitable for multiple fields and meets high-standard coating requirements. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the accompanying drawings described below are only some embodiments of the utility model.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0033] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0034] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0035] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, proposes a waterproof coating device, including: a frame 1; a support plate 2, the support plate 2 is movably arranged relative to the frame 1; a scraper 3, the scraper 3 is swingably arranged relative to the support plate 2, the scraper 3 moves with the support plate 2, the scraper 3 has a scraping part 301, the shortest distance from the scraping part 301 to the support plate 2 is the coating length, and after the scraper 3 swings, the coating length becomes larger or smaller; a wheel part 4, the wheel part 4 is rotatably arranged on the support plate 2, and the wheel part 4 is fixedly connected to the scraper 3.

[0036] In this embodiment, as shown in Figures 1 and 2, after the waterproof coating is prepared, the traditional coating device usually adopts a fixed-structure scraper to apply the coating, and the coating operation is completed by moving the scraper. However, various situations will inevitably be encountered in on-site construction, and different requirements for the coating thickness, such as thicker, thinner or tilted, and the traditional fixed structure cannot adapt well to the above-mentioned various situations, and cumbersome scraper adjustment operations are required, such as manually adjusting the bolts at both ends of the scraper to adjust the height of the scraper. Therefore, in order to solve the above problems and adapt to more comprehensive coating scenarios, a waterproof coating coating device is designed.

[0037] Working principle: the frame 1 basically keeps the same position when working, and the support plate 2 drives the scraper 3 to move, and performs coating operations on walls and other places. During operation, it is mainly realized by the scraper part 301 on the scraper 3; the position of the scraper 3 is adjusted, and the traditional bolt fixing form is changed to an adjustable swinging form, so that after the swing, the shortest distance from the scraper part 301 to the support plate 2 is achieved, and the coating length can be increased or decreased. In other words, the positions of the frame 1 and the support plate 2 remain unchanged, the scraper 3 swings, and the contact area between the scraper 3 and the waterproof coating changes, so that the requirements of different coating thicknesses can be met very accurately, greatly improving flexibility.

[0038] Considering further that directly adjusting the swing angle of the scraper 3 may not be precise enough, and it is inconvenient for workers to directly contact the scraper 301, the power required for the swing of the scraper 3 is provided by rotating the wheel 4 set on the support plate 2. Precise scales can be added around the rotating wheel 4. As long as the wheel 4 rotates to the corresponding scale position, it means that the scraper 301 has been adjusted to the desired coating position.

[0039] Scenarios of different horizontal thicknesses have been adapted, but if faced with an inclination requirement, that is, the coating thickness is constantly changing, since it is not convenient to change the linear horizontal movement of the support plate 2 to make it level with the required inclination angle, there are the following two ways to solve the above problem: The first way is to use the wheel part 4 that actively drives the scraper 3 to swing and adjust, so that it is provided on the support plate 2 and through a power source such as a motor located on one side of the wheel part 4, so that the swing angle of the scraper 3 is constantly changing during the coating process, that is, during the entire coating process, the thickness of the waterproof coating scraped by the scraper 301 is constantly increasing or decreasing to meet the requirements.

[0040] The second method, as shown in Figure 3, is provided at the bottom of the frame 1 with a wheel body that can simultaneously drive the frame 1 to move and adjust the entire inclination angle of the frame 1. The rotation of the wheel body can drive the frame 1 to move to the working position. Since the waterproof coating coating device itself is heavy, even if there is a wheel body at the bottom, it will not affect the stability of the coating work. It is sufficient to ensure that the wheel body does not rotate during operation, and by adjusting the position of the wheel body, that is, two symmetrical support blocks are movably provided on the frame 1, and the wheel body is rotatably provided between the two symmetrical support blocks. After the support block moves away from or close to the ground, the movement angle of the support plate 2 can be adjusted, and then, under the premise of fixing the swing angle of the scraper 3, the waterproof coating can be coated under the inclination requirement.

[0041] In summary, the innovative design of this waterproof coating coating device significantly improves the accuracy and efficiency of the coating process and reduces costs through the combination of precise control, dynamic adaptability, efficient operation, stability and easy maintenance. It is suitable for multiple fields and meets high-standard coating requirements.

[0042] Furthermore, the scraper 3 has a rotating shaft, and the rotating shaft is fixedly arranged at the center position of the wheel part 4.

[0043] In this embodiment, as shown in FIG. 2 , the rotating shaft of the scraper 3 is fixedly connected to the center position of the wheel portion 4 , in other words, they are coaxially arranged, so that the swing angle of the scraper 3 can be precisely controlled by rotating the wheel portion 4 .

[0044] Furthermore, the support plate 2 has a groove 201 , the scraper 3 is swingably disposed in the groove 201 , the bottom of the groove 201 has a curved surface 202 , the scraper 3 abuts against the curved surface 202 , and the scraping portion 301 is exposed from the groove 201 .

[0045] In this embodiment, as shown in Figures 1 and 2, a groove 201 is further provided on the support plate 2, and the scraper 3 and the wheel portion 4 are arranged therein to provide a certain degree of protection therein, and both are exposed from the groove 201 to ensure that the coating operation and the angle changing operation are normally implemented. On the other hand, an arc surface 202 is provided at the bottom of the groove 201 to abut against the arc surface 202 at the bottom of the scraper 3 to ensure the stability of the scraper 3 during the swinging process and provide a guiding effect.

[0046] Furthermore, the wheel portion 4 is rotatably disposed in the groove 201 , there are two wheel portions 4 , the two wheel portions 4 are respectively located at two ends of the scraper 3 , and the length of the groove 201 is equal to the sum of the length of the scraper 3 and the width of the two wheel portions 4 .

[0047] In this embodiment, as shown in Figures 1 and 2, two wheel portions 4 are arranged at both ends of the scraper 3, and the length of the groove 201 is equal to the sum of the length of the scraper 3 and the width of the two wheel portions 4, ensuring that the components in the groove 201 will not fall easily, ensuring the stability of the entire structure, and making it convenient for workers to adjust the swing angle of the scraper 3 from both sides of the waterproof coating coating device.

[0048] Furthermore, the support plate 2 is rectangular, there are three support plates 2, and the three support plates 2 are hingedly connected in sequence along the length direction of the support plate 2. The hinge axis of the support plate 2 is perpendicular to the swing axis of the scraper 3, and the hinge axis of the support plate 2 is parallel to the moving direction of the support plate 2.

[0049] In this embodiment, as shown in Figures 1 and 2, the support plate 2 is limited to be rectangular, which is convenient for production and installation, and provides stable support for the scraper 3. The three support plates 2 are hingedly connected in sequence along their length direction, and the hinge axis of the support plate 2 is perpendicular to the swing axis of the scraper 3, and the hinge axis of the support plate 2 is parallel to the moving direction of the support plate 2. The support plate 2 in the middle is movably set on the frame 1. In this way, it can adapt to working environments with vertical angles such as corners. At the same time, the scrapers 3 on at least two support plates 2 are performing coating operations. Or if it is not a vertical angle, but a working environment with other angles, it is only necessary to adjust the angles between the support plates 2.

[0050] Furthermore, the wheel portion 4 has an elastic protrusion 5 on the side away from the scraper 3 . There are a plurality of elastic protrusions 5 , which are arranged circumferentially. After the wheel portion 4 rotates, the elastic protrusions 5 press against or release the inner wall of the groove 201 .

[0051] In this embodiment, as shown in Figures 1 and 2, in order to prevent the angle of the scraper 3 from not being fixed under the conditions of the rotational freedom of the shaft and the wheel 4 due to the reaction force applied to the scraper 3 during the coating process, a plurality of circumferentially arranged elastic protrusions 5 are provided on the side of the wheel 4 away from the scraper 3. By utilizing interference fit, when the wheel 4 rotates to adjust the angle, the elastic protrusion 5 will be stuck in the groove 201 and pressed against the inner wall of the groove 201, so that the angle of the scraper 3 is fixed.

[0052] Furthermore, there are a plurality of grooves 201 , and the plurality of grooves 201 are arranged at intervals along the moving direction of the support plate 2 .

[0053] Furthermore, it also includes: a screw rod 6, which is rotatably arranged on the frame body 1, and the axial direction of the screw rod 6 is parallel to the moving direction of the support plate 2, and the support plate 2 is threadedly connected to the screw rod 6.

[0054] In this embodiment, as shown in FIG. 2 , a plurality of grooves 201 arranged at intervals along the moving direction of the support plate 2 correspond to a plurality of scrapers 3, respectively, thereby greatly improving the coating quality, and the waterproof coating is coated in turn by the plurality of scrapers 3; at the same time, by utilizing the nut-screw principle, a screw 6 is rotatably provided on the frame 1, so that the support plate 2 is threadedly connected with the screw 6, and then the motor on the frame 1 drives the screw 6 to rotate to control the movement of the support plate 2, thereby stably completing the coating operation.
