Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary devices for decoration projects, and particularly to an intelligent wall painting integrated device for interior decoration. Background Art

[0002] With the rapid development of society, people's demand for housing is also increasing day by day. Painting the interior walls is a very important step. At present, through continuous improvement of the wall painting method, spraying the powder material on the wall by direct spraying is the method with the shortest time consumption and the highest efficiency. However, in the actual application process, when painting the wall by direct spraying, the powder material is likely to stack thickly at the intersection of two adjacent spraying positions, resulting in an uneven situation on the painted wall. It is often necessary to perform a grinding treatment on the position where the powder material is thick later, which increases the operation time, labor cost, and reduces the work efficiency.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0032] In the embodiments of the present invention, in order to solve the problems in the prior art such as easy powder stacking, inconsistent painting thickness, increased operation time, and low work efficiency, a scraper is added to timely level the wall surface after spraying the powder, so that the spraying of the powder and the leveling are carried out synchronously, shortening the operation duration and improving the work efficiency. The embodiments of the present invention will be introduced in detail below:

[0033] Such as Figures 1-10 shown, an intelligent wall painting integrated device for indoor decoration includes a painting substrate 1, a spraying cover 2, and a scraping plate 3. The spraying cover 2 is installed on the painting substrate 1 and is used for spraying the powder. The scraping plate 3 is installed on the painting substrate 1. There are two scraping plates 3, and the two scraping plates 3 are symmetrically arranged up and down. The scraping plate 3 is divided into two parts: a first section 3c and a second section 3d. The second section 3d is parallel to the side line of the painting substrate 1. In the case of taking the second section 3d as a reference, the first section 3c is in an inclined state;

[0034] Specifically referring to Figure 1 and 5 , from the above structural description, it can be seen that the function of the spraying cover 2 is to spray the powder evenly on the wall surface with a certain width. The painting substrate 1 moves up and down along the wall surface. In the following description of the full text of the embodiments of the present invention, the starting point of the upward movement of the painting substrate 1 is used as the starting point. The movement trajectory of the painting substrate 1 can be specifically understood as the following trajectory: The painting substrate 1 first moves upward. When it moves to the highest point, the painting substrate 1 moves sideways by a certain distance. Then the painting substrate 1 moves downward. When the painting substrate 1 moves to the lowest point, the painting substrate 1 continues to move sideways by the same distance. Next, according to the length of the wall surface, the above operations are repeated several times, and the powder can be sprayed onto the wall surface through the spraying cover 2;

[0035] Since in the embodiments of the present invention, two scraping plates 3 that are symmetrically arranged up and down are installed on the painting substrate 1, and in addition, the first sections 3c of the two scraping plates 3 are in an inclined state, during the spraying operation of the spraying cover 2 according to the above process, the first sections 3c of the scraping plates 3 always slide along the overlapping area between two adjacent spraying positions. During the sliding process of the scraping plate 3, a small gap is always maintained between the scraping plate 3 and the wall surface, and this gap is the thickness of the powder to be sprayed on the wall surface. When the scraping plate 3 slides up and down, the thicker part of the powder stack is continuously horizontally leveled and spread under the scraping of the first section 3c of the scraping plate 3. Until the powder laterally moves out of contact with the first section 3c of the scraping plate 3, at this time, on the one hand, the powder falls under the action of gravity, and on the other hand, the powder that has not fallen will also be leveled under the action of the second section 3d of the scraping plate 3, which can timely level the wall surface after spraying the powder, so that the spraying of the powder and the leveling are carried out synchronously, shortening the operation duration and improving the work efficiency.

[0036] Based on the above embodiments, inclined surfaces are provided at both opposite ends of the second section 3d of the two scraping plates 3. Due to the setting of this inclined surface, the thickness of the second section 3d of the scraping plate 3 near the first section 3c is greater than the thickness of the second section 3d of the scraping plate 3 far from the first section 3c;

[0037] For the specific structures of the first section 3c and the second section 3d of the scraping plate 3, please refer to Figure 9 , and the following can continue to elaborate on part of the process in the above embodiments. As can be seen from the above embodiments, the powder that has not fallen under the action of the first section 3c of the scraping plate 3 will continue to be leveled under the action of the second section 3d of the scraping plate 3. Due to the inclined surface structure of the second section 3d of the scraping plate 3, the powder can continue to perform a lateral leveling and spreading movement under the scraping of the second section 3d of the scraping plate 3, making the leveling efficiency of the powder higher;

[0038] Refer to the attached Figure 10 It can be seen that mounting brackets 4 are fixedly provided at both opposite ends of the two scraping plates 3. A rotating shaft 5 is rotatably provided on the mounting bracket 4, and a brush roller 6 is fixedly sleeved on the rotating shaft 5. Here, for the convenience of connection, in the embodiments of the present invention attached Figure 4 , the brush roller 6 and the scraping plate 3 are shown on the same drawing alone, and the brush roller 6 and the scraping plate 3 are in a planar view. As can be seen from the above drawings, the brush roller 6 protrudes from the end of the scraping plate 3 facing the wall. Since the outer part of the brush roller 6 is a soft hair-like structure, during the process of the scraping plate 3 scraping the powder on the wall, the brush roller 6 can always be in stable contact with the wall, and the powder sprayed on the wall can be basically leveled through the brush roller 6. Through the cooperation of the brush roller 6 and the scraping plate 3, the flatness of the powder spraying can be further enhanced.

[0039] Based on the above embodiments, a sliding hole having the same shape as the scraping plate 3 is provided on the painting substrate 1, and the scraping plate 3 slidably penetrates through the sliding hole. A roller 7 is rotatably provided at the central position of the painting substrate 1 at the end opposite to the spraying cover 2. Two spiral chutes 8 are provided on the circumferential outer wall of the roller 7. Guide bent rods 9 are fixedly provided at both ends of the two scraping plates 3 close to the roller 7. The ends of the guide bent rods 9 far from the scraping plates 3 are slidably installed in the corresponding spiral chutes 8. The included angle between the starting points of the two spiral chutes 8 is 90 degrees. Specifically, as Figure 3 shown, when the painting substrate 1 is in the initial position, the scraping plate 3 located below extends towards the wall and cooperates with the wall in contact, and the scraping plate 3 located above faces away from the wall. A transmission gear 10 is coaxially fixedly provided at the end of the roller 7 facing away from the painting substrate 1. A housing 11 is fixedly provided on the side of the painting substrate 1 opposite to the spraying cover 2. A sliding column 12 is slidably penetrated through the housing 11. A toothed structure is provided on the part of the sliding column 12 located inside the housing 11, and the toothed structure on the sliding column 12 meshes with the transmission gear 10;

[0040] It further includes a bottom plate 13, on which a guiding plate 14 is fixedly arranged. At one end of the outer shell 11 facing away from the painting substrate 1, a fixing sleeve 15 is fixedly arranged. The fixing sleeve 15 is slidably sleeved on the guiding plate 14. At one end of the guiding plate 14 facing away from the outer shell 11, a closed-loop track groove 16 is arranged. The closed-loop track groove 16 is of a parallelogram structure and is composed of a first track groove 16a, a second track groove 16b, a first branch groove 16c and a second branch groove 16d. The lengths of the first track groove 16a and the second track groove 16b are the same, and the lengths of the first branch groove 16c and the second branch groove 16d are the same. The first track groove 16a and the second track groove 16b are in a parallel state, and the first branch groove 16c and the second branch groove 16d are in a parallel state. The two ends of the first track groove 16a and the second track groove 16b are respectively connected through the first branch groove 16c and the second branch groove 16d. At both ends of the sliding column 12 located outside the outer shell 11, connecting columns 17 are fixedly arranged. At one end of the two connecting columns 17 facing away from the sliding column 12, a linkage column 18 is fixedly arranged. The linkage column 18 is located on the side of the guiding plate 14 facing away from the outer shell 11. At one end of the linkage column 18 facing the guiding plate 14, a guiding column 19 is fixedly arranged. The guiding column 19 is slidably installed in the closed-loop track groove 16;

[0041] Based on the above structural description, during the working process of the embodiment of the present invention, when the painting substrate 1 is in the initial position, at this time, the guiding column 19 is located at the connection of the first track groove 16a and the first branch groove 16c. When the painting substrate 1 starts to move upward, the guiding column 19 first slides upward along the first track groove 16a. During this process, the scraping plate 3 located below scrapes the powder sprayed on the wall surface, while the scraping plate 3 located above does not perform the scraping operation. When the guiding column 19 slides to the top of the first track groove 16a and slides into the second branch groove 16d, the guiding column 19 drives the linkage column 18, the connecting column 17 and the sliding column 12 to move horizontally. During the horizontal movement of the sliding column 12, the toothed structure on the sliding column 12 drives the transmission gear 10 to rotate. The rotation of the transmission gear 10 drives the roller 7 to rotate. When the roller 7 rotates, through the guiding action of the spiral chute 8 on the guiding bent rod 9, the scraping plate 3 located above and the scraping plate 3 located below exchange positions, that is, when the painting substrate 1 moves upward, the scraping plate 3 located below scrapes the powder on the wall surface. When the painting substrate 1 moves downward, the scraping plate 3 located above scrapes the powder on the wall surface. The painting substrate 1 laterally moves a certain distance, and then the painting substrate 1 ends moving upward and starts to move downward. The painting substrate 1 first slides along the second branch groove 16d and slides from the second branch groove 16d into the second track groove 16b, moves downward along the second track groove 16b to the lowest point and slides into the first branch groove 16c. At this time, the painting substrate 1 ends moving downward. By repeating the above process, the wall surface can be painted.

[0042] Based on the above embodiments, a storage bin 20 is fixedly arranged at the top end of the bottom plate 13 away from the guide plate 14. A discharge pipe 21 is communicated with the storage bin 20. One end of the discharge pipe 21 facing away from the storage bin 20 is communicated with a feeding pump 22. The output end of the feeding pump 22 is communicated with a branch pipe 23. The output end of the branch pipe 23 is communicated with an intermediate pipe 24. Both ends of the intermediate pipe 24 are communicated with an extended flexible hose 25;

[0043] Two connecting pipes 26 are fixedly arranged through the painting substrate 1. As can be seen from the attachment Figure 5 Two connecting pipes 26 are symmetrically located on the painting substrate 1. Both of the two connecting pipes 26 are communicated with the spraying cover 2. The two connecting pipes 26 are rigid pipes. Further, the connection and fixation of the spraying cover 2 can be completed only by relying on the two connecting pipes 26. A plurality of atomizing nozzles 27 are uniformly arranged on the side of the spraying cover 2 facing away from the painting substrate 1. The two connecting pipes 26 penetrate through the outer shell 11, and the output ends of the extended flexible hoses 25 are connected with the corresponding connecting pipes 26;

[0044] During the implementation of the embodiments of the present invention, the storage bin 20 first stores the powder materials. The feeding pump 22 is turned on, and the powder materials in the storage bin 20 are conveyed through the feeding pump 22. Under the action of the feeding pump 22, the powder materials flow through the discharge pipe 21, the feeding pump 22, the branch pipe 23, the intermediate pipe 24, the extended flexible hose 25 and the connecting pipe 26 in sequence and then enter the spraying cover 2. Then, the powder materials are sprayed out through a plurality of atomizing nozzles 27 on the spraying cover 2, realizing the painting of the wall surface, with high automation efficiency and high working efficiency.

[0045] Based on the above embodiments, fixing seats 28 are fixedly arranged at the four corners of the bottom end of the bottom plate 13. Rotating wheels 29 are rotatably arranged at the bottom ends of the fixing seats 28. The rolling direction of the rotating wheels 29 is horizontal with the wall surface. A support frame 30 is fixedly arranged at the central position of the bottom end of the bottom plate 13. A support shaft 31 is rotatably arranged on the support frame 30. A driving gear 32 is fixedly sleeved on the support shaft 31. A driving motor 33 is fixedly arranged at the bottom end of the bottom plate 13. One end of the support shaft 31 is in transmission connection with the output end of the driving motor 33;

[0046] During the implementation of this embodiment, first, the device is moved to a specified position so that when the painting substrate 1 is in the initial position, the scraping plate 3 located below is in contact with the wall surface. More specifically, before spraying, a toothed track 34 is first laid on the ground. The length of the toothed track 34 is consistent with the length of the wall surface to be sprayed indoors, and the driving gear 32 meshes with the toothed track 34. After spraying starts, the support shaft 31 and the driving gear 32 are driven to rotate by the driving motor 33. During the rotation of the driving gear 32, the bottom plate 13 and the entire device installed on the bottom plate 13 are driven to move. The movement trajectory of the bottom plate 13 always remains horizontal with the wall surface. The side shift of the painting substrate 1 is realized by driving the bottom plate 13 to move through the driving motor 33. The movement of the painting substrate 1 has a high degree of automation and high work efficiency.

[0047] Based on the above embodiments and their implementation processes, more specifically, a transmission motor 35 is fixedly arranged at the top end of the bottom plate 13. A transmission shaft 36 is arranged at the top output end of the transmission motor 35. External threads are arranged on the circumferential outer wall of the transmission shaft 36. The fixing sleeve 15 is screwed onto the transmission shaft 36. The height of the transmission shaft 36 is the same as the height of the guide plate 14. The height of the guide plate 14 is adapted to the height of the wall surface to be sprayed, so that the complete spraying of the wall surface can be completed.

[0048] Based on the above embodiments, telescopic grooves are provided at the positions near the top end of the inner wall of the first track groove 16a and the positions near the bottom end of the inner wall of the second track groove 16b. A limiting column 37 is slidably arranged in the telescopic groove. A compression spring 38 is arranged between the limiting column 37 and the inner wall of the telescopic groove;

[0049] More specifically, when the guide post 19 slides upward along the first track groove 16a to near the topmost position, the guide post 19 presses the limiting column 37 into the telescopic groove. At this time, the compression spring 38 is in a compressed state. When the guide post 19 slides upward to the topmost position, at this time, the guide post 19 moves above the limiting column 37. At this time, the guide post 19 releases the acting force on the limiting column 37. The limiting column 37 extends out of the telescopic groove under the action of the compression spring 38 and plays a role in limiting the guide post 19. The inclination angles of the telescopic groove, the limiting column 37, the first branch groove 16c, and the second branch groove 16d are the same. When the guide post 19 moves downward, the limiting column 37 automatically guides the guide post 19 into the second branch groove 16d. In order to facilitate the guide post 19 to press the limiting column 37 into the telescopic groove, a slope is arranged at one end of the limiting column 37 opposite to the moving direction of the guide post 19, which can make it smoother for the guide post 19 to push the telescopic column into the telescopic groove. Similarly, when the guide post 19 slides into the second track groove 16b, the limiting column 37 located in the second track groove 16b also plays a role in limiting and guiding the guide post 19, making the entire working process more stable and smooth.

[0050] Based on the above embodiments, a fairing 39 is provided at the output end of the spraying cover 2. The fairing 39 bundles the powder ejected from a plurality of atomizing nozzles 27 to prevent the powder from splashing and improve economic efficiency.

[0051] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
