Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying device technology, and in particular to a spraying device with a quick-change spray head. Background Technology
[0002] Spraying is a coating method that uses a spray gun or disc atomizer to disperse the material into uniform and fine droplets using pressure or centrifugal force, and then applies the mixture to the surface of the object being coated. It can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of these basic spraying methods, such as high-flow-rate low-pressure atomization spraying, thermal spraying, automatic spraying, and multi-group spraying. Using spraying technology, coatings with wear-resistant, corrosion-resistant, heat-insulating, conductive, insulating, sealing, lubricating, and other special mechanical and chemical properties can be obtained on various substrates. However, spraying equipment requires changing the nozzle in advance before spraying, thus necessitating a quick-change spraying device.
[0003] According to the patent application CN 220658069U, a spraying device with replaceable nozzles is described as follows: "This utility model relates to the field of spraying technology and discloses a spraying device with replaceable nozzles, including a frame, a processing mechanism on the outside of the frame, a rigid feeding tube on one side of the replacement mechanism, a flexible feeding tube fixedly connected to the top of the rigid feeding tube, a spraying head at the bottom of the replacement mechanism, and a fixing sleeve fixedly connected to the outer wall of the rigid feeding tube. A fixing cylinder is fixedly connected to the outer wall of the fixing sleeve, and a sliding plate is slidably connected to the inner wall of the fixing cylinder. A spring is fixedly connected to one side of the sliding plate. This spraying device with replaceable nozzles, through the replacement mechanism, can reinforce the connection between the first threaded connector and the second threaded connector under the elastic action of the spring and the cooperation of the insertion rod. While achieving quick replacement of the spraying head, it can also reduce the instability of the connection between the second threaded connector and the first threaded connector, reducing the possibility of loosening and falling off, and enhancing the practicality of the device."
[0004] Regarding the above description, the applicant believes the following issues exist: The device effectively reinforces the connection between the first and second threaded connectors through the elastic action of the spring and the clever cooperation of the insert rod. This design not only ensures a tight connection between the two but also enables rapid replacement of the spray head, greatly improving work efficiency. Simultaneously, due to the synergistic effect of the spring and the insert rod, the connection stability between the second and first threaded connectors is significantly improved, reducing the possibility of loosening or detachment, thereby enhancing the practicality and reliability of the entire device.
[0005] However, despite its excellent performance in connection and reinforcement, the device presents some inconveniences in actual operation. Specifically, after the spray head is connected to the first threaded connector, it is necessary to further secure the spray head using a rotating block and a plug. This step not only increases the complexity of operation but also makes the entire device relatively cumbersome to use. For applications requiring frequent spray head replacements, this cumbersome procedure undoubtedly reduces work efficiency and increases operational difficulty. Utility Model Content
[0006] To overcome the problem of the cumbersome operation procedure for changing the nozzle.
[0007] The technical solution of this utility model is as follows: a spraying device with a quick-change nozzle, including a base plate; it also includes a support column and a fixing component. The support column is fixedly connected to the top of the base plate, and the fixing component is provided at the bottom of the base plate. A top plate is fixedly connected to the top of the support column, and a spraying material storage box is fixedly connected to the top of the top plate. A connecting pipe is fixedly connected to the outside of the spraying material storage box. A horizontal adjustment device is fixedly connected to the bottom of the top plate, and a vertical adjustment device is provided at the bottom of the horizontal adjustment device. An electric push rod is provided at the bottom of the vertical adjustment device. A spraying device is fixedly connected to the output end of the electric push rod. A fixing pipe is fixedly connected to the bottom of the spraying device. A rotating ring is rotatably connected inside the fixing pipe. A connecting ring cylinder is fixedly connected to the bottom of the rotating ring. A spraying pipe is rotatably connected inside the rotating ring. A sliding plate is fixedly connected inside the spraying pipe. A rotating plate is rotatably connected inside the connecting ring cylinder. A sliding clamp is rotatably connected to the end of the rotating plate away from the connecting ring cylinder. A hollow screw cylinder is fixedly connected inside the connecting ring cylinder. A sliding cross ring is threadedly connected to the outside of the hollow screw cylinder. A nozzle is provided inside the spraying pipe.
[0008] Preferably, a groove is provided at the corresponding position of the sliding plate and the sliding clamp, and the sliding clamp is slidably connected inside the sliding plate.
[0009] Preferably, a groove is provided at the corresponding position of the connecting ring cylinder and the sliding cross ring, and the sliding cross ring is slidably connected inside the connecting ring cylinder.
[0010] Preferably, four sets of rotating plates and sliding clamps are provided, with the four sets of sliding clamps arranged in a circumferential array inside the sliding plates.
[0011] Preferably, the fixing component includes a placement frame, which is fixedly connected to the top of the base plate. A motor is fixedly connected to the outside of the placement frame, and a screw is fixedly connected to the output end of the motor. A clamping plate is threadedly connected to the outside of the screw, and a limit rod is fixedly connected to the inside of the placement frame.

[0013] Preferably, the clamping plate has through holes at the corresponding positions of the clamping plate and the limiting rod, and the clamping plate is slidably connected to the outside of the limiting rod.
[0014] The beneficial effects of this utility model are as follows: By rotating the rotating ring, the rotating plate connected to the outside of the ring cylinder can be driven to rotate. This rotation further causes the sliding clamp on the rotating plate to slide inside the sliding plate. As the sliding clamp moves, it gradually disengages from the inner wall of the nozzle, allowing the nozzle to be easily removed from the inside of the spray tube. After removing the old nozzle, a new nozzle can be quickly placed inside the spray tube. Next, rotating the rotating ring again will drive the rotating plate to rotate again. As the rotating plate rotates, the sliding clamp slides inside the sliding plate and gradually approaches the newly installed nozzle, ultimately achieving a firm fixation of the new nozzle. Throughout the process, the nozzle can be quickly replaced and fixed through a simple rotation operation. This method not only simplifies the operation steps but also improves the efficiency of nozzle replacement, making equipment maintenance and upkeep more convenient. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-6This utility model provides an embodiment of a spraying device with a quick-change nozzle, including a base plate 1; it also includes a support column 21 and a fixing assembly. The support column 21 is fixedly connected to the top of the base plate 1, and the fixing assembly is provided at the bottom of the base plate 1. A top plate 22 is fixedly connected to the top of the support column 21, and a spraying material storage box 23 is fixedly connected to the top of the top plate 22. A connecting pipe 24 is fixedly connected to the outside of the spraying material storage box 23. A horizontal adjustment device 25 is fixedly connected to the bottom of the top plate 22, and a vertical adjustment device 26 is provided at the bottom of the horizontal adjustment device 25. An electric push rod 27 is provided at the bottom of the vertical adjustment device 26, and a spraying nozzle 28 is fixedly connected to the output end of the electric push rod 27. The bottom of the spraying device 28 is fixedly connected to a fixed tube 29. A rotating ring 210 is rotatably connected inside the fixed tube 29. A connecting ring cylinder 211 is fixedly connected to the bottom of the rotating ring 210. A spraying pipe 214 is rotatably connected inside the rotating ring 210. A sliding plate 217 is fixedly connected inside the spraying pipe 214. A rotating plate 215 is rotatably connected inside the connecting ring cylinder 211. A sliding clamp 216 is rotatably connected to the end of the rotating plate 215 away from the connecting ring cylinder 211. A hollow screw cylinder 212 is fixedly connected inside the connecting ring cylinder 211. A sliding cross ring 213 is threaded onto the outside of the hollow screw cylinder 212. A spray nozzle 218 is installed inside the spraying pipe 214. When it is necessary to spray... When replacing the spray head 218, rotating the rotating ring 210 drives the rotating plate 215 outside the connecting ring cylinder 211 to rotate, causing the rotating plate 215 to drive the sliding clamp 216 to slide inside the sliding plate 217. This disengages the sliding clamp 216 from the inner wall of the spray head 218, allowing the spray head 218 to be removed from the spray tube 214. Then, the new spray head 218 is inserted into the spray tube 214. Rotating the rotating ring 210 again drives the rotating plate 215 outside the connecting ring cylinder 211 to rotate, causing the rotating plate 215 to drive the sliding clamp 216 to slide inside the sliding plate 217, thus fixing the spray head 218 in place. The sliding plate 217 and the sliding clamp 216... A groove is provided at the corresponding position of the nozzle 218, and the sliding clamp 216 is slidably connected to the inside of the sliding plate 217. The sliding clamp 216 is provided to facilitate the fixing of the nozzle 218. A groove is provided at the corresponding position of the connecting ring cylinder 211 and the sliding cross ring 213, and the sliding cross ring 213 is slidably connected to the inside of the connecting ring cylinder 211. The sliding cross ring 213 is provided to facilitate the use of the hollow screw cylinder 212 to restrict the rotating ring 210. There are four sets of rotating plates 215 and sliding clamps 216. The four sets of sliding clamps 216 are arranged in a circumferential array inside the sliding plate 217. The rotating plate 215 is provided to facilitate the sliding clamps 216 to slide inside the sliding plate 217.
[0024] Please see Figure 6In this embodiment, the fixing component includes a placement frame 31, which is fixedly connected to the top of the base plate 1. A motor 32 is fixedly connected to the outside of the placement frame 31, and a screw 33 is fixedly connected to the output end of the motor 32. A clamping plate 34 is threadedly connected to the outside of the screw 33. A limit rod 35 is fixedly connected inside the placement frame 31. The presence of the motor 32 facilitates the provision of power for the rotation of the screw 33. Sliding grooves are provided at corresponding positions of the placement frame 31 and the clamping plate 34, and the clamping plate 34 is slidably connected inside the placement frame 31. The presence of the clamping plate 34 facilitates the fixing of the sprayed parts. Through holes are provided at corresponding positions of the clamping plate 34 and the limit rod 35, and the clamping plate 34 is slidably connected outside the limit rod 35. The presence of the placement frame 31 facilitates the provision of an installation base for other components.
[0025] When replacing the spray head 218 during operation, rotating the rotating ring 210 causes the rotating plate 215 outside the connecting ring cylinder 211 to rotate, causing the rotating plate 215 to drive the sliding clamp 216 to slide inside the sliding plate 217. This disengages the sliding clamp 216 from the inner wall of the spray head 218, allowing the spray head 218 to be removed from the spray tube 214. A new spray head 218 is then inserted into the spray tube 214, and the rotating ring 210 is rotated to drive the rotating plate 211 outside the connecting ring cylinder 211 to rotate. The rotating plate 215 of the part rotates, causing the rotating plate 215 to drive the sliding clamp 216 to slide inside the sliding plate 217, thereby fixing the spray head 218 with the sliding clamp 216. Then, by placing the part to be sprayed on the top of the placement frame 31, the clamping plate 34 outside the screw 33 is driven by the motor 32 to slide outside the limiting rod 35, thereby fixing the part to be sprayed. Then, the position of the spray head 218 is adjusted by the vertical adjustment device 26 in conjunction with the electric push rod 27, thereby spraying the part to be sprayed.
[0026] Through the above steps, rotating the rotating ring 210 drives the rotating plate 215 connected to the outside of the ring cylinder 211 to rotate. This rotation further causes the sliding clamp 216 on the rotating plate 215 to slide inside the sliding plate 217. As the sliding clamp 216 moves, it gradually disengages from the inner wall of the spray head 218, allowing the spray head 218 to be easily removed from the inside of the spray tube 214. After removing the old spray head 218, a new spray head 218 can be quickly inserted into the inside of the spray tube 214. Next, rotate the rotating ring 210 again. This action will drive the rotating plate 215 to rotate again. As the rotating plate 215 rotates, the sliding clamp 216 slides inside the sliding plate 217 and gradually moves closer to the newly installed nozzle 218, finally achieving a firm fixation of the new nozzle 218. Throughout the process, the nozzle 218 can be quickly replaced and fixed through a simple rotation operation. This method not only simplifies the operation steps but also improves the efficiency of replacing the nozzle 218, making the maintenance and upkeep of the equipment more convenient.
[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
