Description

Technical Field

[0001] The present invention belongs to the technical field of spraying equipment, and particularly relates to an automatic spraying equipment for the production of wall surfaces in decorative engineering. Background Art

[0002] Building decoration is the abbreviation of building decoration and fitment engineering. Building decoration is a process of various treatments on the inner and outer surfaces and spaces of buildings by using decoration materials or ornaments to protect the main structure of the buildings, improve the physical properties, service functions of the buildings, and beautify the buildings. Building decoration is an indispensable part of people's lives. Wall spraying equipment plays an important role in building decoration, especially in the construction process of large-area walls. Compared with the traditional brushing method, spraying equipment can save a large amount of time cost, reduce the labor intensity of workers, and at the same time achieve a delicate spraying effect on the wall, making the wall paint coating smoother and more delicate, improving the aesthetic sense and ornamental value of interior decoration.

[0003] Currently, for the wall surfaces to be sprayed, on the one hand, the spraying areas are inconsistent, and on the other hand, there are cases such as switch bottom boxes on different walls. When the existing spraying equipment is carrying out spraying work, for the first point mentioned above, it is mostly achieved by controlling the movement and adjustment of the equipment in multiple directions. The disadvantages are that it cannot ensure the accuracy of the equipment position after adjustment, that is, it is easy to cause the possibility of overlapping spraying on the wall surface, and the work process is limited. For the second point, the existing spraying equipment generally sprays from top to bottom. Considering the installation position of the spray head, when there is a switch bottom box, the spraying work will still continue, which will cause the spraying material to be sprayed into the bottom box, not only causing waste of the spraying material to a certain extent, but also affecting the subsequent cleaning process. Processing costs and labor costs still need to be invested, and the use requirements cannot be met. Summary of the Invention

Specific embodiments

[0029] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0030] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0031] Embodiment, as Figures 1 to 10As shown in the figure, an automatic spraying device for the production of decorative engineering walls includes a spraying device body. The spraying device body includes a moving frame 1. Above the moving frame 1, there is a vertical frame 2. On the moving frame 1 on one side of the vertical frame 2, there is also a material box for storing spraying materials. The materials in the material box can be transported to the forward spraying component 6 by a pump body. On one side of the vertical frame 2, there is a lifting component 3 that can be adjusted vertically. On one side of the lifting component 3, there is a longitudinal movement component 4 that can be adjusted longitudinally. For the established lifting component 3 and longitudinal movement component 4, they both include components such as slide bars and sliders. The lifting component 3 can make the device be adjusted vertically, and the longitudinal movement component 4 can make the device be adjusted horizontally, enabling the device to be adjusted in different directions, providing convenient conditions for the development of spraying work. For the driving of the lifting component 3 and longitudinal movement component 4, the same driving method as that of the laser engraving head applied in a laser engraving machine in the prior art can be selected, and the specific details will not be elaborated here. To ensure the smooth progress of spraying work, a spraying mechanism is provided at the output end of the longitudinal movement component 4. The spraying mechanism includes a mounting frame 5. On the mounting frame 5, there is a forward spraying component 6. Above both sides of the mounting frame 5, there are extended spraying components 7. Among them, the established forward spraying component 6 can spray the wall area to be sprayed frontally to ensure the spraying effect. The established extended spraying components 7 can, on the basis of the forward spraying component 6, extend a certain spraying range relatively to meet the use requirements of the spraying device in dealing with different wall ranges and improve the work process. Further, the forward spraying component 6 includes a guide pipe 61 established in the mounting frame 5. On one side of the guide pipe 61, there is a liquid inlet valve 611. On one side of the liquid inlet valve 611, there is a on-off cylinder 62, and its output end is connected to the switch of the liquid inlet valve 611. When it is necessary to transport the external spraying materials to the spraying component, first control the on-off cylinder 62 to operate, make its output end act on the liquid inlet valve 611 to open and close it, and then control the external pump body to operate to transport the spraying materials in the material box to the spraying component to ensure the smooth progress of spraying work. On the other side of the liquid guide pipe, there is a self-controlled nozzle 10 with a on-off function. For the established self-controlled nozzle 10, it has the function of spraying the spraying materials onto the wall, and also has the function of freely opening and closing. When performing spraying work, the self-controlled nozzle 10 is internally connected to ensure that the spraying materials are sprayed onto the wall. When the movement adjustment process of the spraying device encounters a position where spraying work is not required, such as a switch bottom box, on the spraying path, the self-controlled nozzle 10 can be controlled to be disconnected to achieve the closing of the output of the spraying materials. When the spraying device is moved away from the spraying area, the self-controlled nozzle 10 is controlled to be connected again. Its opening and closing process is convenient, which can not only ensure the spraying work process but also achieve fast action, with simple and convenient operation, greatly improving the use functionality of the device and ensuring the use requirements.A connecting frame 8 is provided on the outer side of the mounting frame 5, and a cover body 9 designed in a trapezoidal shape is provided on the connecting frame 8. The established cover body 9 can, to a certain extent, restrict the spraying area of the spraying material during the spraying process, improve the spraying effect, and meet the use requirements;

[0032] In the above process: The established forward spraying assembly 6 can spray the wall area to be sprayed on the front side to ensure the spraying effect. The established extended spraying assembly 7 can, on the basis of the forward spraying assembly 6, extend a certain spraying range relatively to meet the use requirements of the spraying equipment for different wall ranges, improve the working process. Regarding the established self-controlled nozzle 10, it has the function of spraying the spraying material onto the wall, and also has the function of freely turning on and off. When performing the spraying work, the inside of the self-controlled nozzle 10 is connected to ensure that the spraying material is sprayed onto the wall. When the movement adjustment process of the spraying equipment causes the spraying path to encounter a position where spraying work is not required, such as a switch bottom box, etc., the self-controlled nozzle 10 can be controlled to disconnect to achieve the closing of the output of the spraying material. When the spraying equipment moves away from the spraying area, the self-controlled nozzle 10 is controlled to connect again. Its opening and closing process is convenient, and while ensuring the spraying work process, it can also achieve quick action, with simple and convenient operation, greatly improving the use functionality of the device and ensuring the use requirements; This device is reasonably designed, simple in structure, convenient to process, and on the one hand, it is suitable for the spraying work on large walls, reducing the possibility of repeated spraying and improving the working process. On the other hand, it can perform breakpoint spraying on the processing area during the spraying process of the equipment, reducing the possibility of material waste, saving costs, and ensuring the smooth progress of the spraying work, ensuring the spraying effect, and effectively meeting the use requirements.

[0033] In order to enable the spraying equipment body to have the spraying function on a large range of walls, adapt to walls of different specifications, and improve the usability of the device, the extended spraying component 7 includes a limiting mechanism 71 arranged above both sides of the mounting frame 5. The limiting mechanism 71 includes a carrier plate 711, which is arranged above the mounting frame 5. Limiting wheels 712 are arranged above both sides of the carrier plate 711. The cross-section of the limiting wheel 712 is designed in a concave shape. For the established limiting mechanism 71, there are two groups, and the specific installation positions are adapted according to the length of the housing 72. And the two groups of limiting mechanisms 71 can conveniently carry the moving plate 713 to ensure the convenience during its movement adjustment. The gap between the two limiting wheels 712 of one group of the limiting mechanism 71 provides convenience for the placement of the moving plate 713. A moving plate 713 is arranged between the two limiting wheels 712, and a housing 72 is arranged above the moving plate 713. An automatic control type spray head 10 is also arranged on the outer side of the housing 72. Among them, for the established housing 72, pipes can also be arranged inside it, and the pipes are connected to the automatic control type spray head 10. When spraying materials are conveyed in the pipes, they can be sprayed out through the automatic control type spray head 10. When it is not in use, the automatic control type spray head 10 is in a disconnected state and no materials will be sprayed out, which has strong practicability. A Z-shaped frame 73 is arranged above the mounting frame 5, and a driving cylinder 74 is arranged on the Z-shaped frame 73, and its output end is connected to the outer side of the housing 72. Specifically described as: when the spraying range of the forward spraying component 6 is insufficient, control the driving cylinder 74 to operate, so that its output end acts on the outer side of one side of the housing 72, driving the housing 72 to realize movement adjustment under the action of the limiting mechanism 71, so as to expand the spraying area to a certain extent. Of course, the left and right two extended spraying components 7 can be freely controlled to adapt to different usage requirements, greatly improving the practicability of the spraying equipment.

[0034] In order to ensure the smooth conveying of the spraying materials, a liquid distribution pipe 11 is arranged on the mounting frame 5 near the liquid inlet valve 611, and one end of it is communicated with the liquid guiding pipe. Above one end of the housing 72 near the geometric center of the mounting frame 5, a liquid inlet pipe 12 is arranged, and one end of the liquid inlet pipe 12 is communicated with the pipes in the extended spraying component 7. Of course, a pipeline is also arranged between the liquid distribution pipe 11 and the liquid inlet pipe 12 to realize the connection, providing a prerequisite for the conveying of the spraying materials between the forward spraying component 6 and the extended spraying component 7. That is to say: the spraying materials conveyed to the liquid guiding pipe through the liquid inlet valve 611 can, on the one hand, be distributed therein and sprayed out through the automatic control type spray head 10, and on the other hand, can be conveyed to the liquid inlet pipe 12 through the liquid distribution pipe 11 and the pipeline. After the spraying materials enter through the liquid inlet pipe 12, they are then output to each automatic control type spray head 10 through the pipes, providing convenience for the realization of the spraying work and ensuring the continuity of the feeding of the spraying materials.

[0035] In order to enable the spraying equipment to freely control different wall conditions when spraying the spray material toward the wall, especially to achieve breakpoint spraying for the setting position of the switch bottom box, etc., to reduce the possibility of material waste, the automatic control nozzle 10 includes a mounting tube 13, a connecting tube 14 and a nozzle 15 which are sequentially arranged from top to bottom, a locking shell 16 is arranged on the outer side of the mounting tube 13, an electromagnetic push rod 17 is arranged on the outer side of the mounting tube 13 above the locking shell 16, a through groove 131 is opened on the upper part of the mounting tube 13, a conical hole 132 is arranged below the through groove 131, a positioning frame 133 is arranged in the through groove 131, a first sealing mechanism 18 is arranged in the positioning frame 133, a stabilizing frame 141 is arranged in the connecting tube 14, and a second sealing mechanism 18 is arranged above the stabilizing frame 141. The lower end of the mounting tube 13 is provided with an extension shell 135 with an L-shaped cross section, and a linkage mechanism 22 is provided below the locking shell 16 to facilitate the movement and adjustment of the connecting tube 14. Further, for the mounting tube 13, its upper end is connected to the pipelines in the forward spraying assembly 6 and the extended spraying assembly 7, such as a threaded connection, which is convenient for the installation and establishment of the device. The connecting tube 14 is connected to the mounting tube 13 by means of the locking shell 16. When the two are connected in coordination, the automatic nozzle 10 is connected to realize the derivation and supply of the spraying material. When the two are separated, the first sealing mechanism 18 will extend to seal the port of the mounting tube 13, and the second sealing mechanism 19 will extend to seal the port of the connecting tube 14, so as to realize the derivation and supply of the spraying material. The disconnection effect is shown, and as for the establishment of the nozzle 15, it is under the connection of the above two that the spraying material can be sprayed out in a specific way and act on the wall to complete the corresponding spraying work, which is specifically described as follows: when the spraying equipment is in the process of spraying: the installation tube 13 and the connecting tube 14 are tightly matched at the pipe mouth, and the locking shell 16 will also limit and tighten the connection between the installation tube 13 and the connecting tube 14 to prevent it from loosening. In this way, the spraying material can be guided out from the outside of the connection point where the first sealing mechanism 18 and the second sealing mechanism 19 are connected, and transported into the nozzle 15, and then sprayed to the outside through the nozzle 15. When it is necessary to close the nozzle to achieve breakpoint closure during the mobile spraying process, the control signal is output to the electromagnetic push rod 17. The control signal makes it run, and drives the locking shell 16 to move toward the direction close to the liquid guide tube. At the same time, under the action of the linkage mechanism 22, the connecting tube 14 moves in the opposite direction, which provides convenient conditions for the extension of the first sealing mechanism 18 and the second sealing mechanism 19, thereby respectively realizing the action of closing the installation tube 13 and the connecting tube 14, and the spraying material is no longer exported, so as to realize the breakpoint disconnection. After the breakpoint spraying is completed in the spraying area, the electromagnetic push rod 17 is controlled to disconnect the power supply, and its reset will act on the locking shell 16 to reset it. On the one hand, it will act on the linkage mechanism 22, so that the connecting tube 14 cooperates with the installation tube 13 again, and on the other hand, it will limit the connection between the connecting tube 14 and the installation tube 13, thereby improving its establishment stability.Meet the usage requirements.

[0036] To ensure a good opening / closing or on / off effect in the self-controlled nozzle 10, the first sealing mechanism 18 includes an upper conical head 181 adapted to the conical hole 132. Above the upper conical head 181, there is an adjusting rod 182 that can move relative to the positioning frame 133. A compression spring 183 is sleeved outside the adjusting rod 182. The second sealing mechanism 19 includes a lower conical head 191. Below the lower conical head 191, there is a linkage rod 192 that can move and adjust relative to the stable frame 141. For the established linkage rod 192, its lower end penetrates to the outside of the stable frame 141 and can extend into the spray pipe 15 to achieve linkage. A compression spring 193 is sleeved outside the linkage rod 192 between the lower conical head 191 and the stable frame 141. Sealing rings 20 are provided on the outside of both the upper conical head 181 and the lower conical head 191. The established positioning frame 133 and stable frame 141 are respectively connected to the inner walls of the installation pipe 13 and the connecting pipe 14. Specifically described as: For the established first sealing mechanism 18 and second sealing mechanism 19, their working principles are the same. When the connecting pipe 14 is fitted with the installation pipe 13, the upper conical head 181 is pushed into the installation pipe 13, and the lower conical head 191 is pushed into the connecting pipe 14. There is a gap between the outside of the upper conical head 181 and the lower conical head 191 after cooperation and the conical hole 132. This provides convenience for the export of the spraying material. Moreover, this design can improve the conveying process of the spraying material to a certain extent and ensure the smoothness of the export of the spraying material. When the installation pipe 13 and the connecting pipe 14 are separated, the upper conical head 181 will be pushed outwards under the action of the compression spring 183, and the lower conical head 191 will be pushed outwards under the action of the compression spring 193. At the same time, the sealing ring 20 will move with the upper conical head 181 and the lower conical head 191 respectively and fully fit at the conical hole 132 to ensure its sealing performance and meet the usage requirements.

[0037] In order to achieve a stable connection between the installation pipe 13 and the connection pipe 14 and reduce the possibility of their deviation, an outer convex cover 161 is provided at the geometric center inside the locking shell 16. Among them, a placement groove adapted to it is provided on the outer side of the connection pipe 14 corresponding to the position where the outer convex cover 161 is established to ensure that the locking shell 16 can move conveniently. A ring groove 134 is provided on the outer side of the installation pipe 13 corresponding to the outer convex cover 161. The establishment of this ring groove 134 provides a placement space for the establishment of the outer convex cover 161. A V-shaped elastic piece 162 is arranged inside the outer convex cover 161 and penetrates through the installation pipe 13. A fitting groove 142 is provided in the connection pipe 14 corresponding to the V-shaped elastic piece 162. The extended V-shaped elastic piece 162 is led out through the installation pipe 13 and is engaged with the fitting groove 142, thus providing a prerequisite for the locking shell 16 to connect the installation pipe 13 and the connection pipe 14. A ring plate 163 is provided on the inner side of the locking shell 16 above the outer convex cover 161. A telescopic spring 164 is provided above the ring plate 163 and is sleeved on the outer side of the installation pipe 13. For the established telescopic spring 164, when the locking shell 16 is pulled outwards to separate the installation pipe 13 and the connection pipe 14, the ring plate 163 will press the telescopic spring 164. When the locking shell 16 moves in the reverse direction and connects the installation pipe 13 and the connection pipe 14, the telescopic spring 164 will also extend and provide a pressing force for the reset process of the locking shell 16, and also provide convenient conditions for the subsequent connection of the connection pipe 14 and the installation pipe 13. Specifically described as: the outer convex cover 161 can move with the locking shell 16. When the locking shell 16 performs the connection function, the V-shaped elastic piece 162 extends into the fitting groove 142 of the connection pipe 14 through the installation shell 231. In this way, the locking shell 16 can connect the installation pipe 13 and the connection pipe 14 to ensure its stability. When the electromagnetic push rod 17 is controlled to operate and drive the locking shell 16 to move to one side, the V-shaped elastic piece 162 will move with the locking shell 16 and be pressed into the outer convex cover 161 by the installation pipe 13, disengaging the connection between the equipment components. In this way, the establishment of the above equipment can not only facilitate the connection between the installation pipe 13 and the connection pipe 14, but also make the separation between the above components more convenient, with simple and convenient operation and good use functionality. At the same time, for the established V-shaped elastic piece 162, its own elastic performance can be pressed in together with the separation of the installation pipe 13 and the connection pipe 14, thus realizing the disconnection function and improving the use functionality of the device and meeting the use requirements.

[0038] To ensure the smoothness of material export, the cross-section of the nozzle 15 is designed in a T shape, and its upper part is threadedly connected to the connecting pipe 14. A spiral blade 151 that integrates the functions of fixing and feeding is arranged in the nozzle 15. The spiral blade 151 is designed in a converging shape from top to bottom. A stabilizing pipe 152 is arranged above the inner side of the spiral blade 151 and is threadedly connected to the lower part of the stabilizing frame 141. That is to say, when the nozzle 15 is threadedly connected to the connecting pipe 14, as the nozzle 15 is gradually screwed in, the stabilizing pipe 152 slowly approaches the stabilizing frame 141 and is threadedly connected to the outer side of its lower end, ensuring the connection stability between the devices. A lifting rod 153 is arranged in the stabilizing pipe 152, and its upper end abuts against the lower part of the linkage rod 192. Its lower end penetrates through the nozzle 15. A matching spring 154 is arranged on the outer side of the lifting rod 153 located in the stabilizing pipe 152. That is to say, the lifting rod 153 can be adjusted vertically relative to the stabilizing pipe 152, and its lifting also cooperates with the insertion of the linkage rod 192. After the nozzle 15 is connected to the connecting pipe 14, the upper end of the lifting rod 153 contacts and abuts against the lower end of the linkage rod 192. A receiving groove 155 is opened at the lower part inside the nozzle 15, and a semi-circular groove 156 is opened in the nozzle 15 near the lower end of the spiral blade 151. A sealing cover 157 adapted to the semi-circular groove 156 is arranged on the outer side of the lifting rod 153. Spray holes 158 are arranged on the lower side inside the nozzle 15. Specifically described as: when the connecting pipe 14 is stably connected to the installation pipe 13, the linkage rod 192 will be pressed downward towards the nozzle 15 and act on the lifting rod 153, causing the lifting rod 153 to drive the sealing cover 157 away from the semi-circular groove 156. In this way, the spraying material falls through the installation pipe 13 and the connecting pipe 14, is spirally output by the spiral blade 151, then is conveyed into the nozzle 15 through the semi-circular groove 156, and finally, the spraying material is exported through the spray holes 158 and sprayed on the wall surface, ensuring the smooth progress of the spraying work and meeting the use requirements.

[0039] In order to cooperate with the operation of the electromagnetic push rod 17, facilitate the convenient separation of the installation pipe 13 and the connecting pipe 14, and thus provide convenient conditions for the first sealing mechanism 18 and the second sealing mechanism 19 to seal the installation pipe 13 and the connecting pipe 14 respectively, a jacking mechanism 21 is arranged in the installation pipe 13 close to the connecting pipe 14. The jacking mechanism 21 includes a jacking rod 211 designed in a T shape. A positioning plate 212 is arranged on the outer side of the jacking rod 211 and is movably adjusted relative to the inside of the installation pipe 13. A jacking spring 213 is sleeved on the outer side of the jacking rod 211 above the positioning plate 212. Specifically described as: when the electromagnetic push rod 17 operates and pulls the locking shell 16 to move, the compressed jacking spring 213 elongates and acts on the positioning plate 212, so that the outer end of the jacking rod 211 extends out and acts on the end of the connecting pipe 14, enabling the connecting pipe 14 to move away from the installation pipe 13. Under the action of the linkage mechanism 22, the separation between the two components is realized, providing convenient conditions for the subsequent extension of the first sealing mechanism 18 and the second sealing mechanism 19.

[0040] In order to enable the movement adjustment of the locking shell 16, the connecting pipe 14 can be moved closer to or away from the installation pipe 13 to ensure the smooth realization of the linkage action. The linkage mechanism 22 includes a linkage gear 221 arranged on the extension shell 135. A first rack 222 is arranged on the outer side of the connecting pipe 14 on one side of the linkage gear 221. A second rack 223 is arranged on the inner side of the locking shell 16 on the other side of the linkage gear 221. The first rack 222 and the second rack 223 are arranged in central symmetry about the linkage gear 221 and are meshed with it. Specifically described as: at least two groups of the linkage mechanism 22 are arranged and are mirror-symmetrically arranged about the geometric center of the installation pipe 13. When the locking shell 16 drives outward under the action of the electromagnetic push rod 17, the second rack 223 moves together with the locking shell 16 and acts on the linkage gear 221. When the linkage gear 221 rotates, it will act on the first rack 222, causing the connecting pipe 14 to move away from the installation pipe 13, providing convenient conditions for the separation of the installation pipe 13 and the connecting pipe 14. When the control of the electromagnetic push rod 17 is withdrawn and the locking shell 16 moves reversely to reset, the second rack 223 will move with it again and act on the linkage gear 221. By using the rotation of the linkage gear 221 to mesh with the first rack 222, the connecting pipe 14 moves towards the direction close to the installation pipe 13, providing a prerequisite for the connection between the pipe fittings and ensuring the stability of the connection.

[0041] In order to further improve the usability of the device and equipment, especially to complete the cleaning inside the pipe and reduce the waste of the sprayed wall materials, a cleaning mechanism 23 is provided in the forward spraying assembly 6. The cleaning mechanism 23 includes a mounting shell 231 connected to one end of the mounting frame 5. A driving gear 232 is arranged inside the mounting shell 231. A driving rod 233 is arranged outside the driving gear 232. A meshing gear 234 is arranged on one side of the driving gear 232. A lead screw 235 is arranged inside the mounting shell 231 corresponding to the meshing gear 234. A lead screw nut 236 is arranged on one side of the meshing gear 234 and can rotate circumferentially relative to the mounting shell 231. A limiting sleeve 237 is arranged on the other side of the meshing gear 234. Among them, for the established limiting sleeve 237, its function is to play an auxiliary limiting role for the lead screw 235 to ensure the convenience of its feeding movement during rotation. For the established lead screw nut 236, on the one hand, it is rotatably connected to the mounting shell 231, and on the other hand, it can rotate together with the meshing gear 234. One end of the lead screw 235 is provided with a moving disk 238, which is adapted to the inner side of the material guide pipe 61. A cleaning head assembly and other components can be established on the other side of the moving disk 238 to ensure the use effect of the cleaning mechanism 23. Of course, a sealing strip can also be established between the outer circumference of the moving disk 238 and the inner wall of the pipe to ensure the sealing effect at this place to a certain extent. The specific description is as follows: The driving rod 233 is connected to an external driving device, used to receive the driving power and act on the driving gear 232. The rotation of the driving gear 232 causes the meshing gear 234 to rotate, and drives the lead screw nut 236 to rotate circumferentially relative to the mounting shell 231. When the lead screw nut 236 rotates, due to the established situation between it and the lead screw 235 inside it, the lead screw 235 will be driven to rotate to a certain extent, and thus act on the moving disk 238, making it feed and move in the material guide pipe 61 in a rotating manner. In this way, the material attached to the inner wall of the pipe can be cleaned. Until the material is concentrated towards the automatic control nozzle 10 in the middle position, the material is sprayed out through the automatic control nozzle 10. This operation can achieve the centralized collection of the material inside the pipe, reduce the possibility of its waste, and save costs.
