Description

Technical Field

[0001] This invention relates to the field of non-ferrous metal smelting and rolling technology, specifically to an automatic cleaning device with five small spray nozzles and its cleaning method. Background Technology

[0002] Die-casting machine spray heads are typically made of aluminum alloy. The five-piece small spray head is one type of die-casting machine spray head. Die-casting machine spray heads offer good adaptability: small temperature difference on the mold surface; small temperature difference in the spray head eliminates the need for drying, shortening the spraying cycle time and improving production efficiency; no moisture residue; fine atomization: enabling small spray volumes, and the flow rate is unaffected by liquid pressure. However, existing die-casting machine spray heads generate oxides during use, which can clog pipes and nozzles. This blockage results in a small spray volume, a thinner film forming on the mold, and localized oil film breakage, poor demolding properties, and products prone to scratches and sticking. Therefore, operators need to clean the spray heads regularly.

[0003] In the prior art, such as the "Automatic Printhead Cleaning Device" in Chinese Patent Application No. CN113211991A, the device includes: an automatic scraping system, which has a miniature geared motor that can drive the printhead scraper to rotate in both directions, a drive shaft, and a scraper that can scrape away the ink solidified at the printhead; a negative pressure ink suction system, which has an ink station that moistens and maintains the printhead and has the function of absorbing waste ink, and an ink pump that sucks out the ink accumulated in the printhead to make the ink path smooth; and a scraper position detection system, which has a bushing fixed on the drive shaft to detect the working position of the scraper and a position detection switch fixed on the housing to emit a position detection signal.

[0004] In existing technologies, spray heads are usually cleaned manually, which often requires 1-2 people and takes more than eight hours. Manual cleaning is time-consuming, labor-intensive, and ineffective. In addition, it is difficult to clean every angle of the spray head manually, and the release agent remaining on the surface of the spray head can corrode the mold, thereby reducing the service life of the mold.

[0005] Therefore, we propose an automatic cleaning device with five small spray nozzles to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic cleaning device with five small spray nozzles to solve the problems mentioned in the background art.

[0011] Preferably, the top of the hydraulic cylinder is fixedly installed to one end of the support frame, and a drive rod is fixedly connected to the bottom of the hydraulic cylinder.

[0012] Preferably, the top of the second hydraulic cylinder is fixedly connected to one end of the drive rod, one end of the second hydraulic cylinder is slidably installed on the inner side of the support frame, and the other end of the second hydraulic cylinder is fixedly connected to one end of the fixed plate.

[0013] Preferably, two clamping plates are symmetrically and rotatably installed at both ends of the fixing plate, and the inner side of the clamping plates is fixedly connected to one side of the rubber pad.

[0014] Preferably, the bottom end of the base is fixedly installed to the bottom of the rotating motor, and the front side of the base is fixedly installed to both ends of the controller, and the top of the support plate is rotatably connected to the bottom of the turntable.

[0015] A cleaning method for an automatic cleaning device with five small spray nozzles includes the following steps:

[0016] S1. Place the three spray heads to be cleaned on the three conveyor plates respectively. Rotate the motor to drive the turntable to rotate. At the same time, hydraulic cylinder one drives hydraulic cylinder two to move downward. When one of the conveyor plates and the spray head to be cleaned rotates to the bottom of the clamping plate, the clamping plate moves the two sides of the spray head. Hydraulic cylinder two drives the two clamping plates to rotate inward, thereby clamping the spray head to be cleaned.

[0017] S2. Hydraulic cylinder one drives hydraulic cylinder two and the spray head to be cleaned to move upward a certain distance, and the cleaning fluid is sprayed onto the surface of the spray head. Hydraulic cylinder three drives the brush head to move to the bottom of the spray head through the telescopic rod. The rotating motor drives the brush head to rotate, and the brush head washes the spray head with water.

[0018] S3. During the spray head washing process, clean water in the water supply pipe is continuously sprayed onto the surface of the spray head through the rinsing nozzle, and the brush head washes away the dirt and cleaning solution on the surface of the spray head.

[0019] S4. After cleaning, the rotating motor stops rotating, and the micro vacuum pump creates negative pressure at the suction end, which then evenly suctions and cleans the bottom surface of the spray head that has been rinsed.

[0020] S5. The third hydraulic cylinder controls the extension rod to retract, the first hydraulic cylinder drives the cleaned spray head to move downwards, at this time the receiving plate moves to the bottom of the clamping plate, and the second hydraulic cylinder controls the placement of the cleaned spray head on the receiving plate.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By setting up a cleaning device, hydraulic cylinder one, hydraulic cylinder two and clamping plate work together to automatically clamp and move the spray head to be cleaned to the cleaning position. At the same time, through the coordinated use of pneumatic three-way valve, flushing nozzle and nozzle control components, the flushing nozzle can spray cleaning fluid and clean water onto the surface of the spray head to be cleaned. Simultaneously, the rotating motor drives the brush head to rotate, and the brush head washes away the dirt and cleaning fluid on the surface of the spray head, thereby achieving the effect of automatic cleaning of the spray head. The cleaning device and the rotating conveyor device work together to automatically complete the cleaning of the spray head, eliminating the need for manual cleaning by personnel, reducing the workload of personnel. At the same time, the high-speed rotating brush head can effectively improve the cleaning effect of the spray head, effectively solve the problem of spray head clogging, and improve the product qualification rate.

[0023] 2. By setting up a cleaning component, the brush head rinses away the dirt and cleaning solution on the surface of the spray head. Then, a miniature vacuum pump creates negative pressure at the suction end, which evenly sucks and cleans the bottom surface of the spray head that has been rinsed. This automatic cleaning device uses a method of first washing with water and then vacuuming to clean the surface of the spray head. The suction end effectively ensures that the surface of the spray head is clean and improves the cleaning effect of the spray head. Attached Figure Description

Example 1

[0035] Reference Figure 1-5 As shown: An automatic cleaning device for five small spray nozzles includes a rotary conveying device 1 and a cleaning device 2. One end of the rotary conveying device 1 is fixedly installed to the bottom end of the cleaning device 2. The rotary conveying device 1 includes a base 11, a controller 12, a turntable 13, a support plate 16, and a rotary motor 17.

[0037] like Figures 1-8As shown, the cleaning device 2 includes a cleaning assembly 21, a support frame 22, a pneumatic three-way valve 23, a water supply pipe 24, an infusion pipe 25, a first hydraulic cylinder 26, a second hydraulic cylinder 27, a nozzle control component 29, a rinsing nozzle 30, and a fixing plate 31. One end of the pneumatic three-way valve 23 is fixedly connected to one end of the water supply pipe 24, and the other end of the pneumatic three-way valve 23 is fixedly connected to one end of the infusion pipe 25. The top of the nozzle control component 29 is fixedly connected to the bottom end of the pneumatic three-way valve 23, and the bottom of the nozzle control component 29 is fixedly connected to one end of the rinsing nozzle 30. Component 21 includes a hydraulic cylinder 211, a telescopic rod 212, a rotary motor 213, a housing 214, a brush head 215, a mounting plate 216, and a suction end 218. The bottom of the mounting plate 216 is fixedly mounted to the top of the rotary motor 213, and one end of the mounting plate 216 is fixedly mounted to one end of the telescopic rod 212. The output end of the rotary motor 213 is fixedly connected to the bottom of the housing 214. A miniature vacuum pump 217 is installed inside the housing 214, and the top of the miniature vacuum pump 217 is fixedly connected to the bottom of the suction end 218. The bottom of pump 217 is fixedly connected to the top of mounting plate 216. A filter screen 219 is fixedly connected to the top of housing 214, and the top of housing 214 is fixedly connected to the bottom of brush head 215. The bottom of housing 214 is rotatably mounted to the top of mounting plate 216. One end of telescopic rod 212 is fixedly connected to one end of hydraulic cylinder 211. The outer side of suction end 218 is movably mounted to the inner wall of housing 214. One end of hydraulic cylinder 211 is fixedly mounted to one end of support frame 22. The bottom end of support frame 22 is fixedly mounted to one side of base 11. The top of the support frame 22 is fixedly installed with both ends of the pneumatic three-way valve 23. The top of the hydraulic cylinder 26 is fixedly installed with one end of the support frame 22, and the bottom of the hydraulic cylinder 26 is fixedly connected with a drive rod 28. The top of the hydraulic cylinder 27 is fixedly connected with one end of the drive rod 28. One end of the hydraulic cylinder 27 is slidably installed with the inside of the support frame 22, and the other end of the hydraulic cylinder 27 is fixedly connected with one end of the fixing plate 31. Two clamping plates 32 are symmetrically rotated and installed at both ends of the fixing plate 31, and the inside of the clamping plates 32 is fixedly connected with one side of the rubber pad 33.

[0038] In this embodiment, the rotating motor 17 drives the turntable 13 and the spray head to be cleaned to rotate. While the turntable 13 rotates, the hydraulic cylinder 26 drives the hydraulic cylinder 27 to move downward through the drive rod 28. The clamping plate 32 holds the spray head to be cleaned. The hydraulic cylinder 26 then drives the hydraulic cylinder 27 and the spray head to be cleaned to move upward a certain distance. After the spray head to be cleaned moves to the cleaning position, the rinsing nozzle 31 sprays cleaning liquid and clean water onto the surface of the spray head to be cleaned. The rotating motor 213 drives the brush head 215 to rotate. The brush head 215 rinses the dirt and cleaning liquid off the surface of the spray head, thereby achieving the effect of automatic cleaning of the spray head. After the brush head 215 rinses the spray head clean, the rotating motor 213 is turned off, and the controller 12 controls the micro vacuum pump 217 to be turned on. The micro vacuum pump 217 generates negative pressure at the suction end 218, and the suction end 218 performs uniform suction and cleaning on the bottom surface of the rinsed spray head. Example 3

[0039] like Figures 1-8 As shown, a cleaning method for an automatic cleaning device with five small spray nozzles includes the following steps:

[0040] Step 1: Place the three spray heads to be cleaned on the three conveyor plates 14 respectively. Rotate the motor 17 to drive the turntable 13 to rotate. At the same time, the hydraulic cylinder 26 drives the hydraulic cylinder 27 to move downward. When one of the conveyor plates 14 and the spray head to be cleaned rotates to the bottom of the clamping plate 32, the clamping plate 32 moves the two sides of the spray head. The hydraulic cylinder 27 drives the two clamping plates 32 to rotate inward, thereby clamping the spray head to be cleaned.

[0041] Step 2: Hydraulic cylinder 26 drives hydraulic cylinder 27 and the spray head to be cleaned to move upward a certain distance. The rinsing nozzle 31 sprays the cleaning liquid onto the surface of the spray head. Hydraulic cylinder 211 drives the brush head 215 to move to the bottom of the spray head through the telescopic rod 212. The rotating motor 213 drives the brush head 215 to rotate, and the brush head 215 washes the spray head with water.

[0042] Step 3: During the water washing process of the spray head, the clean water in the water supply pipe 24 is continuously sprayed onto the surface of the spray head through the rinsing nozzle 31, and the brush head 215 washes away the dirt and cleaning solution on the surface of the spray head.

[0043] Step 4: After cleaning, stop rotating the motor 213 and use the micro vacuum pump 217 to generate negative pressure at the suction end 218. The suction end 218 then evenly suctions and cleans the bottom surface of the spray head that has been rinsed.

[0044] Step 5: Hydraulic cylinder 3 211 controls the telescopic rod 212 to retract, and hydraulic cylinder 1 26 drives the cleaned spray head to move downward. At this time, the receiving plate 15 moves to the bottom of the clamping plate 32, and hydraulic cylinder 2 27 controls the placement of the cleaned spray head on the receiving plate 15.

[0045] The usage and working principle of this device are as follows: Before cleaning the spray heads, connect one end of the water supply pipe 24 to the clean water tank and connect one end of the liquid supply pipe 25 to the cleaning liquid tank. The water supply pipe 24 supplies clean water to the pneumatic three-way valve 23, and the liquid supply pipe 25 supplies cleaning liquid to the pneumatic three-way valve 23. First, the operator places the three spray heads to be cleaned on the three conveyor plates 14 respectively. The controller 12 can control the opening and closing of the rotary motor 17, the pneumatic three-way valve 23, the hydraulic cylinder 1 26, the hydraulic cylinder 27, the hydraulic cylinder 3 211, the spray head control component 29, the rotary motor 213, and the micro vacuum pump 217. The controller 12 controls the opening and closing of multiple control components and their coordinated use to complete the cleaning of the spray heads.

[0046] Controller 12 controls the start of rotating motor 17, which drives the top turntable 13 and the spray head to be cleaned to rotate. Simultaneously, hydraulic cylinder 16 drives hydraulic cylinder 27 downwards via drive rod 28. The output end of hydraulic cylinder 27 can drive clamping plate 32 to rotate. When the conveyor plate 14 and the spray head to be cleaned rotate to the bottom of clamping plate 32, clamping plate 32 moves the sides of the spray head. Hydraulic cylinder 27 drives the two clamping plates 32 to rotate inwards, thus clamping the spray head to be cleaned. After the spray head is clamped by clamping plate 32, hydraulic cylinder 16 drives hydraulic cylinder 27 and the spray head to be cleaned to move upwards a certain distance. After the spray head to be cleaned moves to the cleaning position, pneumatic three-way valve 23 controls the infusion pipe 25 to connect with the spray head control component 30. The spray head control component 30 then controls the flushing nozzle 31 to open, spraying the cleaning fluid in the infusion pipe 25 onto the surface of the spray head to be cleaned. At this time, the hydraulic cylinder... The telescopic rod 212 extends, causing the outer casing 214, the rotating motor 213, and the brush head 215 to move to the bottom of the spray head to be cleaned. The rotating motor 213 drives the outer casing 214 and the top brush head 215 to rotate. At the same time, the pneumatic three-way valve 23 controls the water supply pipe 24 to connect with the spray head control component 30. The clean water in the water supply pipe 24 is continuously sprayed onto the surface of the spray head through the rinsing nozzle 31. The brush head 215 washes away the dirt and cleaning liquid on the surface of the spray head, thereby achieving the effect of automatic cleaning of the spray head. The filter screen 219 can prevent impurities from falling into the inner casing 214 during rinsing. The staff only needs to place the spray head to be cleaned on the conveyor plate 14 in sequence. The cleaning device 2 and the rotating conveyor device 1 work together to automatically complete the cleaning of the spray head without the need for manual cleaning by the staff, reducing the workload of the staff. At the same time, the high-speed rotating brush head 215 can effectively improve the cleaning effect of the spray head.

[0047] After the brush head 215 cleans the spray head, the rotating motor 213 is turned off, and the controller 12 controls the micro vacuum pump 217 to start. The micro vacuum pump 217 creates negative pressure at the suction end 218, which then evenly suctions and cleans the bottom surface of the rinsed spray head. This device, through the coordinated use of the pneumatic three-way valve 23, cleaning assembly 21, and clamping plate 32, cleans the spray head surface using a method of first washing with water and then vacuum suction. First, the cleaning solution is sprayed onto the spray head surface, where it mixes with the dirt and oxides. Then, clean water is used to rinse away the cleaning solution and oxides. Finally, the suction end 218 cleans the spray head surface... The remaining water stains on the surface are sucked up and cleaned to effectively ensure the cleanliness of the spray head surface and improve the cleaning effect of the spray head. After the spray head is cleaned, hydraulic cylinder 3 211 controls the extension rod 212 to shorten. The extension rod 212 drives the brush head 215 to move to one side of the spray head. Hydraulic cylinder 1 26 then drives hydraulic cylinder 2 27 and the cleaned spray head to move downward. At this time, the receiving plate 15 just moves to the bottom of the clamping plate 32. Hydraulic cylinder 2 27 controls the clamping plate 32 to rotate outward and open. The cleaned spray head can be placed on the receiving plate 15. The turntable 13 continues to rotate. When the next conveyor plate 14 and the spray head move to the bottom of the clamping plate 32, the above steps are repeated to clean multiple spray heads.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
