[0029] It should be noted that the terms used herein are only for the purpose of describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise, and it should also be understood that when the terms "comprise" and / or "include" are used in the specification, they indicate the presence of a feature, step, operation, device, component and / or combination thereof.

[0030] Reference is made to Figures 1 to 4As shown, according to the embodiment of the present application, a putty spraying and scraping device is provided, which comprises a spraying mechanism 10, a scraping mechanism 20 and a connecting mechanism 30. The spraying mechanism 10 comprises a nozzle 11 for spraying paint; the scraping mechanism 20 comprises a scraper assembly 21, a telescopic assembly 22 and a support part 23, the scraper assembly 21 is rotatably connected with the telescopic assembly 22, the telescopic assembly 22 is connected with the support part 23 and can be telescopically extended and retracted relative to the support part 23; the connecting mechanism 30 is connected with the spraying mechanism 10, the scraping mechanism 20 and an external driving device respectively, and the spraying mechanism 10 and the scraping mechanism 20 are located on the same side of the connecting mechanism 30.

[0031] The external driving device comprises a mechanical arm. When the putty spraying and scraping device is used to perform putty construction on a wall surface, the operation parameters of the mechanical arm are set in advance according to the actual situation of the wall surface and the spraying and scraping requirements, so as to ensure that the mechanical arm can automatically control the putty spraying and scraping device to perform putty spraying and scraping construction on the wall surface. The nozzle 11 on the spraying mechanism 10 can spray putty on the wall surface. The mechanical arm can control the nozzle 11 to be inclined at a certain angle to spray putty on the places that cannot be sprayed horizontally by the nozzle 11. When the nozzle 11 does not need to be inclined to spray putty, the mechanical arm controls the scraper assembly 21 of the scraping mechanism 20 to abut against and adhere to the wall surface. Since the scraper assembly 21 is telescopically connected with the support part 23 through the telescopic assembly 22, and the scraper assembly 21 is rotatably connected with the telescopic assembly 22 (i.e. the scraper assembly 21 can swing in the horizontal direction relative to the telescopic assembly 22), when the scraper assembly 21 abuts against the wall surface, the connection between the scraper assembly 21 and the wall surface is flexible, the scraper assembly 21 has high degrees of freedom, and the scraper assembly 21 can self-adaptively adhere to the wall surface under the extrusion of the mechanical arm according to the situation of the wall surface, so that the scraper assembly 21 can better scrape the wall surface that has been sprayed with putty by the nozzle 11, the scraped wall surface is more flat, the scraping effect is good, and the putty spraying and scraping construction can be performed by the putty spraying and scraping device instead of manual operation, thereby improving the construction efficiency of the putty spraying and scraping.

[0032] Further, the scraper assembly 21 comprises a scraper 211 and a scraper support 212 for fixing the scraper 211, and the scraper support 212 is provided with a connecting part 213 for rotatably connecting with the telescopic assembly 22.

[0033] Reference Figure 1As shown, the scraper 211 is in a sheet structure, when the putty spraying and scraping device is in a horizontal state and the spraying mechanism 10 is located directly above the scraping mechanism 20, the scraper 211 is in an inclined state along the direction parallel to the wall surface, and the angle between the scraper 211 and the wall surface is a predetermined angle along the scraping direction of the scraper 211 (the putty spraying and scraping device is vertically upward or vertically downward), for example, when the predetermined angle is 15°-30°, the uniformity of the putty layer of the wall surface is better. The scraping of the scraper 211 at a suitable angle can improve the quality of the putty layer of the wall surface, that is, the inclination of the scraper can accurately control the flow of putty, reduce the accumulation of putty and the generation of voids, and ensure the uniform thickness of the putty layer of the wall surface. When the scraper 211 is inclined to scrape the putty, it has a certain component force in the direction perpendicular to the wall surface, and this perpendicular component force can compact the putty and reduce the probability of occurrence of air pockets and bubbles. The scraper 211 in the inclined state can also reduce the friction with the wall surface, and the high degree of freedom of the scraper assembly 21 can improve the construction efficiency. The scraper support 212 adopts a wave-shaped sheet structure, which can improve the bending stiffness and has higher strength than the flat plate structure under the same thickness, so as to ensure the stability of the angle of the scraper 211 under high-pressure scraping.

[0034] Further, the telescopic assembly 22 includes a connecting piece 221 and two telescopic components 222, along the length direction of the telescopic component 222, the telescopic component 222 has a first end and a second end arranged oppositely, the telescopic component 222 is fixedly connected with the connecting piece 221 through the first end, and the telescopic component 222 is connected with the support part 23 through the second end and can be telescoped relative to the support part 23 along the length direction of the connecting piece 221.

[0035] Specifically, the telescopic assembly 22 is rotatably connected with the scraper support 212 of the scraper assembly 21 through the connecting piece 221, so that when the scraper assembly 21 is pressed against the wall surface under the action of the mechanical arm, it can move in the horizontal direction relative to the telescopic assembly 22, thereby improving the degree of freedom of the scraper assembly 21 in the horizontal direction (perpendicular to the wall surface), and making the scraper assembly 21 have a certain self-adaptability in the vertical direction of the scraping direction when scraping the putty on the wall surface, so as to better scrape the putty on the wall surface. The first end of the telescopic component 222 of the telescopic assembly 22 is fixedly connected with the connecting piece 221, and the telescopic assembly 22 is connected with the support part 23 through the second end of the telescopic component 222 and can be telescoped relative to the support part 23 along the length direction of the connecting piece 221, so that the scraper assembly 21 has a certain degree of freedom in the length direction of the telescopic assembly 22, so that the scraper assembly 21 can be better pressed against the wall surface under the control of the mechanical arm, and will not exert a large force on the wall surface due to the extrusion of the mechanical arm, thereby preventing the wall putty layer from being damaged, avoiding the inconsistency of the thickness of the putty layer, and improving the flatness of the wall surface when the putty spraying and scraping device of the embodiment is used to spray and scrape putty on the wall surface.

[0036] Further, the connecting piece 221 is provided as an elongated connecting piece, one of the two telescopic components 222 is fixedly connected with one end of the opposite two ends of the elongated connecting piece, the other of the two telescopic components 222 is fixedly connected with the other end of the opposite two ends of the elongated connecting piece, and the middle part of the elongated connecting piece is provided with a connecting protrusion 2211 in the length direction of the elongated connecting piece, and the elongated connecting piece is rotatably connected with the connecting part 213 through the connecting protrusion 2211.

[0037] The two ends of the elongated connecting piece are fixedly connected with the two telescopic components 222, the two telescopic components 222 form a symmetrical structure, which can improve the connection stability between the telescopic component 222 and the elongated connecting piece, improve the anti-deformation ability of the overall structure, reduce the risk of deformation of the telescopic component 222 when the scraping plate mechanism 20 of the putty spraying and scraping device controlled by the mechanical arm performs putty scraping on the wall surface, ensure that the contact pressure between the scraper 211 and the wall surface remains constant, and avoid the uneven thickness of the putty layer caused by the pressure fluctuation due to the change of the angle. The connecting protrusion 2211 at the middle position of the elongated connecting piece serves as the only rotation fulcrum of the scraper assembly 21 and the telescopic assembly 22, which can make the scraper 211 rotate around the fixed axis, and avoid the unstable movement caused by the interference of multiple fulcrums. The protruding structure of the connecting protrusion 2211 can avoid interference between the scraper assembly and the elongated connecting piece when the scraper assembly rotates relative to the elongated connecting piece, and improve the rotatable amplitude of the scraper assembly 21.

[0038] Preferably, the rotatable connection between the connecting protrusion 2211 and the connecting part 213 is a hinge connection, which can limit the rotation of the scraper assembly 21 only around the hinge axis, eliminate multi-degree-of-freedom interference, and ensure the control accuracy of the inclination angle; the hinge shaft cooperates with the hinge in a manner with low wear rate, which can improve the service life of the device.

[0039] Further, the support part 23 includes a support plate 231, the support plate 231 includes a first side and a second side arranged opposite to each other, the telescopic component 222 includes a telescopic rod 2221, a spring 2222 and a guide part 2223, the spring 2222 is sleeved on the telescopic rod 2221, the guide part 2223 is fixed to the second side, the guide part 2223 is provided with a guide hole 2224 in communication with the first side in the length direction, and the telescopic rod 2221 is inserted into the guide hole 2224 of the guide part 2223 after penetrating through the support plate 231 from the first side.

[0040] The guide part 2223 of the telescopic part 222 is arranged on the second side of the support plate 231, and the guide part 2223 has a guide hole 2224 communicating with the first side of the support plate, the end of the telescopic rod 2221 of the spring 2222 is inserted into the guide hole 2224 after passing through the support plate 231 from the first side, so that the telescopic rod 2221 can be telescopically extended and contracted relative to the support plate 231, and the spring 2222 can provide an axial reaction force for the telescopic rod, so as to limit the telescopic movement of the telescopic rod 2221, and make the whole scraper mechanism 20 in a floating state along the length direction of the telescopic assembly 22, so that the scraper 211 of the scraper assembly 21 can be better abutted against the wall surface, thereby improving the putty scraping effect.

[0041] Further, the guide part 2223 comprises one or more of a linear guide rail, a linear bearing and a guide cylinder. When the guide part 2223 is a linear guide rail, a sliding groove is arranged in the guide hole 2224 of the guide part 2223, and a sliding block cooperating with the sliding groove is arranged on the telescopic rod 2221, so that the telescopic rod 2221 can be telescopically extended and contracted relative to the guide part 2223 through the cooperation of the sliding block and the sliding groove. When the guide part 2223 is a linear bearing, a guide shaft is arranged in the guide hole 2224, and the telescopic rod 2221 is fixed on the guide shaft and can be telescopically extended and contracted relative to the guide part 2223. When the guide part 2223 is a guide cylinder, the telescopic rod 2221 is directly inserted into the guide hole 2224 of the guide cylinder, and a predetermined gap is formed between the outer surface of the telescopic rod 2221 and the inner surface of the guide hole 2224, the guide hole 2224 has a limiting part at one end close to the first side of the support plate 231, which can place the telescopic rod 2221 out of the guide hole 2224, and the guide hole 2224 needs to be injected with lubricating oil, so that the telescopic rod 2221 can be better telescopically extended and contracted in the guide hole 2224.

[0042] Further, the elastic limiting part 24 for limiting the horizontal position of the scraper assembly 21 is arranged between the scraper assembly 21 and the support part 23, the first end of the elastic limiting part 24 is connected with the scraper support 212, and the second end opposite to the first end of the elastic limiting part 24 is connected with the edge of the support plate 231.

[0043] Reference Figure 3 and Figure 4As shown, on opposite sides of the same scraper assembly 21, elastic limit pieces 24 are arranged, that is, two elastic limit pieces 24 are arranged between the scraper assembly 21 and the support part 23, and the two elastic limit pieces 24 can realize horizontal direction limiting of the scraper assembly 21. Because the scraper assembly 21 can rotate relative to the telescopic assembly 22 and has high rotation amplitude and high degree of freedom along the left and right sides due to the existence of the connecting protrusion 2211, the two elastic limit pieces 24 can appropriately reduce the rotation amplitude of the scraper assembly 21, so that the scraper assembly 21 does not freely swing when in a non-working state, and does not affect the working swing of the scraper assembly 21 to adapt to the wall surface when in a working state. Reference Figure 1 As shown, when the scraper assembly 21 is in a non-working state, because the telescopic assembly 22 does not have telescopic movement, at this time the elastic limit piece 24 is in a tight state, and the scraper assembly 21 is balanced under the restraint of the two elastic limit pieces 24, which can avoid free swing of the putty spraying and scraping device during transfer or idle stroke to cause faults or safety accidents, thereby improving the safety of the putty spraying and scraping device; Reference Figure 4 As shown, when the scraper assembly 21 is in a working state, the scraper 211 of the scraper assembly 21 closely adheres to the wall surface, and the telescopic rod 2221 of the telescopic assembly 22 moves towards the support plate 231, at this time the elastic limit piece 24 is in a relaxed state, and the scraper assembly 21 can freely rotate, has high degree of freedom and large rotation amplitude on the left and right sides, so that the scraper 211 can find a suitable angle to closely adhere to the wall surface according to the condition of the wall surface. The first end of the elastic limit piece 24 is connected with the scraper support 212, and the second end of the elastic limit piece 24 is connected with the edge of the support plate 231, so that when the telescopic assembly 22 is telescoped, the elastic limit piece 24 can be prevented from being affected by other components.

[0044] Preferably, the elastic limit piece 24 includes a steel wire soft rope, which can be in a tight state when the scraper assembly 21 is in a non-working state to provide rigid constraint and prevent the scraper assembly 21 from freely swinging, thereby ensuring the safety of the device during transfer or idle stroke. The steel wire material is resistant to tensile cycle and dust corrosion, thereby reducing the maintenance frequency of the device. The steel wire soft rope has compact structure, can avoid conflict with the movement track of the telescopic assembly 22, and can reduce the overall weight of the device.

[0045] Further, the scraper mechanism 20 comprises a plurality of scraper assemblies 21 and a plurality of telescopic assemblies 22 corresponding to the plurality of scraper assemblies 21 and rotatably connected to the plurality of scraper assemblies 21, the plurality of telescopic assemblies 22 are respectively connected to the support part 23 and can be telescoped along the length direction of the telescopic assembly 22 relative to the support part 23. The plurality of scraper assemblies 21 work synchronously, can perform multiple batch scraping on the same position of the wall surface, improve the putty batch scraping effect of the wall surface, and shorten the wall surface construction time. The plurality of telescopic assemblies 22 can independently adjust the telescoping amount of the corresponding scraper assembly 21, apply differential pressure to the wall surface, and ensure the uniformity of the overall coating thickness. Each scraper assembly 21 can be independently rotated around the connecting protrusion, and after combination, it is suitable for complex wall surfaces such as arc-shaped and wavy-shaped, reducing the need for manual touch-up. When a single scraper assembly 21 encounters resistance, the remaining scraper assemblies 21 can still maintain operation, avoiding the overall device from stopping, and improving the continuity of construction.

[0046] Further, in the direction away from the spraying mechanism 10, the scraper mechanism 20 comprises a first scraper assembly, a second scraper assembly, and a third scraper assembly, the length of the first scraper assembly is less than the length of the third scraper assembly, the length of the second scraper assembly is less than the length of the third scraper assembly, and the length of the first scraper assembly is equal to the length of the second scraper assembly. When the scraper mechanism 20 performs batch scraping work, the front short scraper assembly 21 and the rear long scraper assembly 21 can cover the scratches left by the front scraper assembly 21 and realize multiple batch scraping, improving the putty batch scraping effect. The telescopic assemblies 22 connected to different scraper assemblies 21 can use springs 2222 with different elastic coefficients to adjust the working pressure of different scraper assemblies 21, for example, the front scraper assembly 21 can be set to a lower working pressure, and the rear scraper assembly 21 can be set to a higher working pressure. To avoid the front scraper assembly 21 from excessively pressing the wall surface and causing putty side overflow, after the front scraper assembly 21 performs preliminary batch scraping on the wall surface, using the rear scraper assembly 21 will not cause putty side overflow and can also improve the tightness and flatness of the putty. When the first scraper assembly and the second scraper assembly with the same length locally miss scraping due to wall surface undulation, the third scraper assembly with a length longer than the first scraper assembly and the second scraper assembly can perform batch scraping on the places missed by the first two scraper assemblies, side overflow, and scratches, significantly improving the batch scraping effect of the wall putty.

[0047] Further, the spraying mechanism 10 further comprises a paint conveying assembly, the paint conveying assembly is arranged in the inside of the connecting mechanism 30, and the paint conveying assembly is provided with an inlet 12 and an outlet 13 at opposite ends, the inlet 12 is connected with an external paint machine, and the outlet 13 is connected with the nozzle 11.

[0048] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects: the scraper assembly and the telescopic assembly are rotatable and telescopically connected, so that the scraper can be self-adapted to the wall surface, avoiding the disadvantages of rigid connection, and cooperating with the scraper to tilt relative to the wall surface for batch scraping, which can accurately control the putty flow, compact the putty, reduce the probability of hollowing and bubbling, improve the uniformity and quality of the putty layer, and improve the scraping effect of the wall putty. The nozzle of the spraying mechanism is arranged on the same side of the scraper mechanism, so that the spraying and scraping are closely connected, and the influence of putty drying and clumping is reduced. At the same time, the mechanical arm can set parameters in advance, automatically control the device construction, and flexibly adjust the nozzle angle, combined with the high degree of freedom of the scraper mechanism, which can efficiently replace manual work and improve the construction efficiency. The telescopic assembly is fixed by two telescopic components and a long strip-shaped connecting piece arranged symmetrically, the connecting protrusion is used as the only rotating fulcrum, the rotating stability of the scraper is ensured, the deformation risk of the telescopic component is reduced, and the constant contact pressure is ensured. The guide part of the supporting part cooperates with the spring, so that the scraper mechanism is in a floating state and is better pressed against the wall surface. Multiple scraper assemblies work synchronously, can batch scrape the same position multiple times, each component is independently adjusted, adapts to complex wall surfaces, does not stop when encountering resistance, and improves the continuity of putty spraying and scraping construction. The elastic limiting piece between the scraper assembly and the supporting part is in a tight state to prevent the scraper from shaking and ensure safety during non-operation; and in the operation state, the elastic limiting piece is in a relaxed state and does not affect the rotation of the scraper. The steel wire soft rope is used as the elastic limiting piece, which is resistant to stretching and corrosion, has low maintenance frequency and compact structure. The paint conveying assembly is arranged in the connecting mechanism, connects the external paint machine and the nozzle, can ensure stable paint conveying, and improves the efficiency of putty spraying and scraping construction.
