Description
Technical Field
[0001] The present invention relates to the technical field of spraying devices, and specifically to a nano-spraying device with a detection function. Background Art
[0002] With the development of industrial technology, simple manual work can no longer meet the market demand. Spraying has developed from manual to industrial automation, and the degree of automation is getting higher and higher. Therefore, the application of spraying production lines is becoming more and more extensive and has penetrated into many fields of the national economy. Spraying equipment has made great progress, and the application of spraying production lines is also becoming more and more extensive and has penetrated into many fields of the national economy, and spraying devices in the construction industry are frequently used.
[0003] The nano-spraying device is used for spray printing on a screen printing stencil. When the spraying device is working, particle impurities or paint solid blocks will be generated at its spraying port and inside the storage tank. The paint solid blocks are very likely to cause blockage of the spraying port. The blockage is divided into two types: semi-blockage and full blockage. Semi-blockage means that there are paint solid blocks in the spraying port. The particle size of the paint solid blocks is small, and the aperture of the spraying port will be affected, resulting in an impact on the spraying uniformity. Full blockage means that there are paint solid blocks in the spraying port. The particle size of the paint solid blocks is large, and the aperture of the spraying port will be completely blocked, which will cause the spraying device to stop working, and will also increase the pressure inside the pipe of the spraying port, and then cause damage to the spraying port. Summary of the Invention
[0004] The purpose of the present invention is to provide a nano-spraying device with a detection function to solve the problems raised in the prior art.
[0005] To achieve the above purpose, the present invention provides the following technical solutions:
[0006] A nano-spraying device with a detection function. The spraying device includes a base assembly, a box body assembly and a spraying assembly. The base assembly is provided with the box body assembly, the box body assembly is provided with the spraying assembly, the spraying assembly is provided with a detection assembly for detecting the internal flow rate and pressure of the spraying assembly, and the spraying assembly is provided with an anti-blocking assembly for preventing blockage of the output end of the spraying assembly. The spraying assembly includes a spraying box, a pump body is provided at the bottom end of the spraying box, and a pipeline is provided at the output end of the pump body.
[0007] Specifically, the nano spraying device is used for spray printing on a screen printing stencil. When the spraying device is working, particulate impurities or paint solid blocks will be generated at its spraying port and inside the storage tank. The paint solid blocks are very likely to cause blockage of the spraying port. The blockage is divided into two types: semi-blockage and complete blockage. Semi-blockage means that there are paint solid blocks in the spraying port. The particle size of the paint solid blocks is relatively small, and the aperture of the spraying port will be affected, resulting in an impact on the spraying uniformity. Complete blockage means that there are paint solid blocks in the spraying port. The particle size of the paint solid blocks is relatively large, and the aperture of the spraying port will be completely blocked, which will cause the spraying device to stop working, and will also increase the pressure inside the pipe of the spraying port, and then cause damage to the spraying port. The box body assembly is used to provide a closed environment to prevent the external environment from affecting the paint surface. The upper surface of the base assembly is provided with a transportation assembly, and the box body assembly is provided with a spraying assembly. The spraying assembly is used for printing on the screen printing stencil. The output end of the spraying assembly is provided with a detection assembly. The detection assembly is used to detect the internal flow rate and pressure of the spraying port and control the anti-blocking assembly to work. The anti-blocking assembly is used to clean the paint solid blocks in the pipe at the output end of the spraying assembly. The spraying tank is used to store the paint, the pump body conveys the paint, and the pipeline transports the paint.
[0008] The output end of the pipeline is provided with a sprayer. The sprayer includes a barrel cavity and a moving ring. The barrel cavity is located at one end of the pipeline. A fixed barrel is arranged inside the barrel cavity. The barrel cavity is fixedly connected with the fixed barrel. One end of the barrel cavity is provided with a nozzle, and the nozzle is fixedly connected with the barrel cavity. A moving ring is arranged inside the fixed barrel. The middle of the moving ring is hollow, and a rotating block is arranged inside the moving ring.
[0009] Specifically, the detection assembly is located at the connection between the sprayer and the pipeline. The barrel cavity is located on the side of the sprayer close to the pipeline. The barrel cavity serves as an external protective shell. The internal space of the barrel cavity is provided with a fixed barrel. One end of the internal space of the fixed barrel is communicated with the pipeline, and the other end of the internal space of the fixed barrel is communicated with the sprayer. A moving ring is arranged inside the fixed barrel. The moving ring is slidably connected with the fixed barrel. The moving ring is normally located in the middle of the fixed barrel. The moving ring and the fixed barrel are on the same central axis. A rotating block is arranged inside the moving ring. The inner wall of the moving ring is rotatably connected with the rotating block.
[0010] The anti-blocking assembly includes a top scraper. The rotating block is rotatably connected with the moving ring. The upper surface of the rotating block is provided with a top scraper. There are several top scrapers. The top scrapers are obliquely fixed. The top of the top scraper is provided with a top plate, and the bottom end of the rotating block is provided with a bottom scraper.
[0011] Specifically, when the coating is in the fixed cylinder for a long time, the coating will solidify, which will affect the flow rate and flow volume in the pipe during spraying, and will also cause an increase in the pressure inside the pipe. The anti-blocking component is used to clean the solidified coating blocks in the fixed cylinder. Since the top scraping knife is fixed obliquely and arranged at equal intervals, the flow pressure generated when the coating passes through will exert a thrust on the top scraping knife. And because the top scraping knife is fixedly connected to the rotating block, and the rotating block is rotatably connected to the moving ring, when the top scraping knife is pressurized, it will start to rotate, and then the top scraping knife will clean the inner wall of the fixed cylinder. The top plate is located at the top of the top scraping knife and is fixedly connected to the top scraping knife. The top plate is used to improve the stability of the top scraping knife. When the lower scraping knife moves to the bottom end of the moving ring, the lower scraping knife contacts the nozzle to clean the nozzle.
[0012] A heating element is sleeved on the outer wall of the cylinder cavity. The fixed end of the heating element is fixedly connected to the outer wall of the cylinder cavity. A heat insulation layer is provided outside the heating element, and the heat insulation layer is fixedly connected to the outer wall of the cylinder cavity.
[0013] Specifically, the heating element is located on the outer wall of the cylinder cavity. The heating element is used to heat the inside of the cylinder cavity to increase the temperature inside the cylinder cavity, reduce the probability of the coating inside the cylinder cavity solidifying, and will also melt the already solidified coating. The heat insulation layer wraps the heating element to provide a sealed environment and improve the heating efficiency.
[0014] A spring is provided at the bottom end of the moving ring. The top end of the spring is fixedly connected to the bottom end of the moving ring, and the bottom end of the spring is fixedly connected to the inner bottom end of the fixed cylinder. An extension block is provided on the outer wall of the moving ring. The extension block is fixedly connected to the moving ring. A sliding groove is provided on the inner wall of the fixed cylinder, and the extension block is slidably connected to the sliding groove.
[0015] Specifically, the spring is used to provide a moving space so that the moving ring can move up and down. When the top scraping knife is pressurized, it will exert a pressure on the rotation. And because the spring provides a moving space, the rotating block will drive the moving ring to move. The movement of the moving ring drives the extension block to move along the sliding groove. The movement of the top scraping knife will also drive the top plate to move. One side of the top plate is in contact with the inner wall of the fixed cylinder. Thus, when the top scraping knife moves downward, it drives the top plate to move downward. The top plate and the top scraping knife cooperate to clean the solidified coating in the cylinder cavity.
[0016] The detection component includes a magnetic column. A magnetic column is provided at the bottom end of the extension block. A coil is provided at the bottom end of the magnetic column. The coil and the magnetic column are on the same central axis. The bottom end of the coil is fixedly connected to the inner bottom end of the cylinder cavity. There is a space between the rotating block and the moving ring. A permanent magnet is provided inside the moving ring. The permanent magnet is fixedly connected to the rotating block. The other end of the permanent magnet is provided with a Hall element, and the Hall element is fixedly connected to the moving ring.
[0017] Specifically, the detection component is used to detect the flow rate of the coating in the barrel cavity and the pressure exerted on the inner wall of the barrel cavity. When the moving ring is pressed and moves downward, the magnetic column of the moving ring also moves downward, causing the magnetic column to pass through one end of the coil. As a result, the magnetic flux in the coil changes, and an electromotive force is generated in the coil. The more the magnetic column passes through, the greater the electromotive force. Since the moving ring moves under the pressure of the coating, when the electromotive force is greater, the flow pressure of the coating in the barrel cavity is greater. When the top scraper is pressed by the rotating block and rotates, the rotation of the top scraper drives the rotating block to rotate, and the rotation of the rotating block drives the permanent magnet to rotate. The magnetic poles approach or move away from the Hall element periodically, resulting in a periodic change in the magnetic field strength around it. The magnetic field change causes the voltage output by the Hall element to fluctuate periodically, so as to judge the rotation speed of the rotating block according to the fluctuation amplitude, and then judge the flow rate of the coating in the barrel cavity.
[0018] Silicone rubber blocks are provided on the wall of the fixed barrel. Both ends of the silicone rubber blocks are fixedly connected to the fixed barrel. Electrode pins are provided at both ends of the silicone rubber blocks. The fixed ends of the electrode pins are fixedly connected to the fixed barrel, and the output ends of the electrode pins are connected to the silicone rubber blocks.
[0019] Specifically, when the inside of the sprayer is blocked, the coating will exert pressure on the inner wall of the barrel cavity, which will cause irreversible damage to the barrel cavity in the long term. Seriously, it will cause damage to the nozzle, barrel cavity and pipeline. During use, when the inner wall of the barrel cavity is pressed, the silicone rubber block is pressed, and the silicone rubber block will deform outward. The silicone rubber block is filled with a conductive material. Two electrode pins are provided on the outer wall of the fixed barrel, and the two electrode pins are connected to the silicone rubber block. When the silicone rubber block deforms, the structure of the conductive material inside it will also be affected, resulting in a change in the voltage value between the two electrode pins. Therefore, according to the change in the voltage value, when the voltage value is greater than the set value, the heating element starts to work to heat the barrel cavity.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] 1. When the flow pressure generated after the coating passes through acts on the top scraper, the top scraper will start to rotate under the pressure, and then the top scraper will clean the inner wall of the fixed barrel. The top plate is located at the top of the top scraper, and the low scraper will also rotate driven by the top scraper. When the low scraper moves to the bottom end of the moving ring, the low scraper contacts the nozzle to clean the nozzle.
[0022] 2. During the use of the present invention, when the inner wall of the barrel cavity is pressed, the silicone rubber block is pressed, and the structure of the conductive material inside it will also be affected, resulting in a change in the voltage value between the two electrode pins. Therefore, according to the change in the voltage value, when the voltage value is greater than the set value, the heating element starts to work to heat the barrel cavity.

[0033] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0034] Embodiment: As Figures 1 to 9 shown, the present invention provides a technical solution of a nano spraying device with a detection function. The spraying device includes a base assembly 1, a box body assembly 2 and a spraying component 3. The base assembly 1 is provided with the box body assembly 2, the box body assembly 2 is provided with the spraying component 3, the spraying component 3 is provided with a detection component 4 for detecting the internal flow rate and pressure of the spraying component 3, and the spraying component 3 is provided with an anti-blocking component 5 for preventing the output end of the spraying component 3 from being blocked. The spraying component 3 includes a spraying box 31, a pump body 32 is provided at the bottom end of the spraying box 31, and a pipeline 33 is provided at the output end of the pump body 32.
[0035] Specifically, the nano spraying device is used for spray printing on a screen printing stencil. When the spraying device is working, particulate impurities or paint solid blocks will be generated at its spraying port and inside the storage tank. The paint solid blocks are likely to cause blockage of the spraying port. The blockage is divided into two types: semi-blockage and complete blockage. Semi-blockage means that there are paint solid blocks in the spraying port. The particle size of the paint solid blocks is relatively small, and the aperture of the spraying port will be affected, resulting in an impact on the spraying uniformity. Complete blockage means that there are paint solid blocks in the spraying port. The particle size of the paint solid blocks is relatively large, and the aperture of the spraying port will be completely blocked, which will cause the spraying device to stop working and increase the internal pressure of the pipe of the spraying port, and further cause damage to the spraying port. The box body assembly 2 is used to provide a closed environment to prevent the external environment from affecting the paint surface. A transportation assembly is provided on the upper surface of the base assembly 1, and a spraying assembly 3 is provided inside the box body assembly 2. The spraying assembly 3 is used for printing on the screen printing stencil. A detection assembly 4 is provided at the output end of the spraying assembly 3. The detection assembly 4 is used to detect the internal flow rate and pressure of the spraying port and control the operation of the anti-blocking assembly 5. The anti-blocking assembly 5 is used to clean the paint solid blocks in the pipe at the output end of the spraying assembly 3. The spraying tank 31 is used to store the paint, the pump body 32 conveys the paint, and the pipeline 33 transports the paint.
[0036] As Figures 2 to 4 shown, a sprayer 6 is provided at the output end of the pipeline 33. The sprayer 6 includes a barrel cavity 61 and a moving ring 62. The barrel cavity 61 is located at one end of the pipeline 33. A fixed barrel 63 is provided inside the barrel cavity 61. The barrel cavity 61 is fixedly connected to the fixed barrel 63. A nozzle 64 is provided at one end of the barrel cavity 61. The nozzle 64 is fixedly connected to the barrel cavity 61. A moving ring 62 is provided inside the fixed barrel 63. The middle of the moving ring 62 is hollow, and a rotating block 65 is provided inside the moving ring 62.
[0037] Specifically, the detection assembly 4 is located at the connection between the sprayer 6 and the pipeline 33. The barrel cavity 61 is located on the side of the sprayer 6 close to the pipeline 33. The barrel cavity 61 serves as an external protective shell. The internal space of the barrel cavity 61 is provided with a fixed barrel 63. One end of the internal space of the fixed barrel 63 is communicated with the pipeline 33, and the other end of the internal space of the fixed barrel 63 is communicated with the sprayer 6. A moving ring 62 is provided inside the fixed barrel 63. The moving ring 62 is slidably connected to the fixed barrel 63. The moving ring 62 is normally located in the middle of the fixed barrel 63. The moving ring 62 and the fixed barrel 63 are on the same central axis. A rotating block 65 is provided inside the moving ring 62. The inner wall of the moving ring 62 is rotatably connected to the rotating block 65.
[0038] As Figure 4 shown, the anti-blocking assembly 5 includes a top scraper 51. The rotating block 65 is rotatably connected to the moving ring 62. A top scraper 51 is provided on the upper surface of the rotating block 65. There are several top scrapers 51. The top scrapers 51 are fixedly arranged obliquely. A top plate 52 is provided at the top end of the top scraper 51. A bottom scraper 53 is provided at the bottom end of the rotating block 65.
[0039] Specifically, when the coating is in the fixed cylinder 63 for a long time, the coating will solidify, which will affect the flow rate and flow volume in the pipe during spraying, and will also cause an increase in the pressure in the pipe. The anti-blocking component 5 is used to clean the solidified coating in the fixed cylinder 63. Since the top scraping knife 51 is fixedly installed obliquely and the top scraping knives 51 are arranged at equal intervals, the flow pressure generated when the coating passes through will generate a thrust on the top scraping knife 51. And because the top scraping knife 51 is fixedly connected to the rotating block 65, and the rotating block 65 is rotatably connected to the moving ring 62, when the top scraping knife 51 is pressed, it will start to rotate, and then the top scraping knife 51 will clean the inner wall of the fixed cylinder 63. The top plate 52 is located at the top of the top scraping knife 51 and is fixedly connected to the top scraping knife 51. The top plate 52 is used to improve the stability of the top scraping knife 51. When the low scraping knife 53 moves to the bottom end of the moving ring 62, the low scraping knife 53 contacts the nozzle 64 to clean the nozzle 64.
[0040] As Figure 4 As shown, a heating element 34 is sleeved on the outer wall of the cylinder cavity 61. The fixed end of the heating element 34 is fixedly connected to the outer wall of the cylinder cavity 61. A heat insulation layer 35 is arranged outside the heating element 34, and the heat insulation layer 35 is fixedly connected to the outer wall of the cylinder cavity 61.
[0041] Specifically, the heating element 34 is located on the outer wall of the cylinder cavity 61. The heating element 34 is used to heat the inside of the cylinder cavity 61 to increase the temperature inside the cylinder cavity 61 and reduce the probability of the coating in the cylinder cavity 61 solidifying. Moreover, it will also melt the already solidified coating. The heat insulation layer 35 wraps the heating element 34 and is used to provide a sealed environment and improve the heating efficiency.
[0042] As Figure 4 As shown, a spring 66 is arranged at the bottom end of the moving ring 62. The top end of the spring 66 is fixedly connected to the bottom end of the moving ring 62, and the bottom end of the spring 66 is fixedly connected to the inner bottom end of the fixed cylinder 63. An extension block 67 is arranged on the outer wall of the moving ring 62, and the extension block 67 is fixedly connected to the moving ring 62. A sliding groove is formed on the inner wall of the fixed cylinder 63, and the extension block 67 is slidably connected to the sliding groove.
[0043] Specifically, the spring 66 is used to provide a moving space so that the moving ring 62 can move up and down. When the top scraping knife 51 is pressed, it will generate a pressure on the rotation. And because the spring 66 provides a moving space, the rotating block 65 will drive the moving ring 62 to move. The movement of the moving ring 62 drives the extension block 67 to move along the sliding groove. The movement of the top scraping knife 51 will also drive the top plate 52 to move. One side of the top plate 52 is in contact with the inner wall of the fixed cylinder 63. Thus, when the top scraping knife 51 moves downward, it drives the top plate 52 to move downward, and the top plate 52 and the top scraping knife 51 cooperate to clean the solidified coating in the cylinder cavity 61.
[0044] As Figure 8 、 Figure 9As shown, the detection component 4 includes a magnetic post 41. The magnetic post 41 is provided at the bottom end of the extension block 67. A coil 42 is provided at the bottom end of the magnetic post 41. The coil 42 and the magnetic post 41 are on the same central axis. The bottom end of the coil 42 is fixedly connected to the inner bottom end of the cylinder cavity 61. There is a space between the rotating block 65 and the moving ring 62. A permanent magnet 43 is provided inside the moving ring 62. The permanent magnet 43 is fixedly connected to the rotating block 65. The other end of the permanent magnet 43 is provided with a Hall element 44. The Hall element 44 is fixedly connected to the moving ring 62.
[0045] Specifically, the detection component 4 is used to detect the flow rate of the paint in the cylinder cavity 61 and the pressure exerted on the inner wall of the cylinder cavity 61. When the moving ring 62 is pressed and moves downward, the moving ring 62 will move the magnetic post 41 downward, causing the magnetic post 41 to pass through one end of the coil 42. As a result, the magnetic flux in the coil 42 will change, and an electromotive force will be generated in the coil 42. The more the magnetic post 41 passes through one end, the greater the electromotive force. Since the moving ring 62 moves under the pressure of the paint, when the electromotive force is greater, the flow pressure of the paint in the cylinder cavity 61 is greater. When the top scraper 51 on the rotating block 65 is pressed and rotates, the rotation of the top scraper 51 will drive the rotating block 65 to rotate. The rotation of the rotating block 65 will drive the permanent magnet 43 to rotate, and the magnetic poles will periodically approach or move away from the Hall element 44, resulting in a periodic change in the magnetic field intensity around it. The magnetic field change causes the voltage output by the Hall element 44 to fluctuate periodically. Thus, the rotation speed of the rotating block 65 is judged according to the fluctuation amplitude, and then the flow rate of the paint in the cylinder cavity 61 is judged.
[0046] As Figure 5 As shown, silicone rubber blocks 45 are provided on the wall of the fixed cylinder 63. Both ends of the silicone rubber blocks 45 are fixedly connected to the fixed cylinder 63. Electrode pins 46 are provided at both ends of the silicone rubber blocks 45. The fixed ends of the electrode pins 46 are fixedly connected to the fixed cylinder 63. The output ends of the electrode pins 46 are connected to the silicone rubber blocks 45.
[0047] Specifically, when the inside of the sprayer 6 is blocked, the paint will exert pressure on the inner wall of the cylinder cavity 61, which will cause irreversible effects on the cylinder cavity 61 in the long term. Seriously, it will cause damage to the nozzle 64, the cylinder cavity 61 and the pipeline 33. During use, when the inner wall of the cylinder cavity 61 is pressurized, the silicone rubber block 45 is pressurized and will deform outward. The silicone rubber block 45 is filled with a conductive material. Two electrode pins 46 are provided on the outer wall of the fixed cylinder 63. The two electrode pins 46 are connected to the silicone rubber block 45. When the silicone rubber block 45 deforms, the structure of the conductive material inside it will also be affected, resulting in a change in the voltage value between the two electrode pins 46. Thus, according to the change in the voltage value, when the voltage value is greater than the set value, the heating element 34 starts to work to heat the cylinder cavity 61.
[0048] Working principle: When the coating passes through, the flow pressure generated will exert a thrust on the top scraping knife 51. Since the top scraping knife 51 is fixedly connected to the rotating block 65, and the rotating block 65 is rotatably connected to the moving ring 62, when the top scraping knife 51 is pressured, it will start to rotate. Then, the top scraping knife 51 will clean the inner wall of the fixed cylinder 63. The top plate 52 is located at the top of the top scraping knife 51 and is fixedly connected to the top scraping knife 51. The top is used to improve the stability of the top scraping knife 51. When the low scraping knife 53 moves to the bottom end of the moving ring 62, the low scraping knife 53 contacts the nozzle 64 to clean the nozzle 64. When the moving ring 62 is pressured and moves downward, the moving ring 62 will move the magnetic column 41 downward, causing the magnetic column 41 to pass through one end of the coil 42. Then, the magnetic flux in the coil 42 will change, and the coil 42 will generate an electromotive force. The more the magnetic column 41 passes through, the greater the electromotive force. Since the moving ring 62 moves under the pressure of the coating, when the electromotive force is greater, the flow pressure of the coating in the cylinder cavity 61 is greater. When the top scraping knife 51 on the rotating block 65 is pressured and rotates, the rotation of the top scraping knife 51 will drive the rotating block 65 to rotate. The rotation of the rotating block 65 will drive the permanent magnet 43 to rotate. The magnetic poles approach or move away from the Hall element 44 periodically, resulting in a periodic change in the magnetic field strength around it. The magnetic field change causes the voltage output by the Hall element 44 to fluctuate periodically. Thus, the rotation speed of the rotating block 65 is judged according to the fluctuation amplitude, and then the flow rate of the coating in the cylinder cavity 61 is judged.
