Description

Technical Field

[0001] This utility model relates to the technical field of spray washing devices, and in particular to a rapid circulating spray washing device. Background Technology

[0002] In the manufacturing of dispensing equipment, the dispensing and bonding between workpieces is a critical process. As the core component of dispensing equipment, the cleanliness of the nozzle of the dispensing valve directly affects the dispensing accuracy, adhesive performance, and product yield. Therefore, thoroughly cleaning the dispensing valve before dispensing is an indispensable process.

[0003] Currently, the industry generally uses a combination of wiping with a lint-free cloth and soaking with a cleaning agent to treat dispensing valve nozzles. Wiping with a lint-free cloth relies on manual operation, which has problems such as uneven cleaning force and low efficiency, and is difficult to effectively remove stubborn stains. While simple soaking can dissolve some contaminants, the cleaning agent cannot form an impact force to remove impurities such as oxide layers and cured adhesives adhering to the nozzle surface. These residual contaminants not only lead to a decrease in dispensing accuracy, but also cause bubbles in the adhesive, and even cause the adhesive layer to peel off in sheets, seriously affecting product quality. To solve the above problems, this application proposes a rapid circulating spray cleaning device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid circulating spray washing device. This device uses a circulating pump to drive the cleaning fluid circulation, and the cleaning fluid sprayed from the spray head creates an impact force, effectively removing contaminants such as oxide layers from the surface of the dispensing valve nozzle. Compared to traditional wiping and soaking methods, the cleaning efficiency is significantly improved. A filter screen is installed to filter and trap impurities in the circulating cleaning fluid. The filter screen and the spray washing box are connected by a detachable magnetic attachment mechanism, facilitating cleaning and replacement of the filter screen.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid circulating spray washing device includes a spray washing tank, a spray washing cover covering the top of the spray washing tank, a water collection tank on the top of the spray washing cover, a circulating pump fixedly connected to the side wall of the spray washing tank, an inlet and an outlet on the circulating pump, an inlet pipe fixedly connected to the inlet, the end of the inlet pipe fixedly connected to the side wall of the spray washing tank, an outlet pipe fixedly connected to the outlet, a spray washing column fixedly connected to the inner wall of the spray washing tank, a spray washing head fixedly connected to the top of the spray washing column, an outlet pipe passing through the spray washing tank and the end of the outlet pipe fixedly connected to the spray washing column, a filter screen inside the spray washing tank, and two disassembly and assembly mechanisms between the spray washing tank and the filter screen.

[0007] Preferably, the disassembly and assembly mechanism includes two fixing blocks fixedly connected to the inner wall of the spray washing box, and iron pillars fixedly connected to the top of each of the two fixing blocks. Two fixing covers fixedly connected to the filter screen are provided through the filter screen. The two iron pillars are respectively inserted into the corresponding fixing covers. Magnets are fixedly connected to the inner walls of the two fixing covers. The two iron pillars are attracted to the magnets in their respective fixing covers.

[0008] Preferably, a protrusion is fixedly connected to the top of the spray washing box, and a groove is provided at the bottom of the spray washing cover, with the protrusion inserted into the groove.

[0009] Preferably, the spray cover has a through-hole for water inlet, and the spray head is disposed through the water inlet.

[0010] Preferably, the outer wall of the spray washing box has four slots, which are respectively distributed on the four sides of the spray washing cover.

[0011] Preferably, the filter screen has a through opening, and a first sealing element is fixedly connected to the inner wall of the through opening. The inner wall of the first sealing element abuts against the outer wall of the spray column. A second sealing element is fixedly connected to the outer wall of the filter screen, and the outer wall of the second sealing element abuts against the inner wall of the spray box.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The cleaning fluid is circulated by a circulating pump. The cleaning fluid sprayed from the spray head can form an impact force, which can effectively remove contaminants such as oxide layer on the surface of the dispensing valve nozzle. The wetting and adhesive removal effect is good. Compared with traditional wiping and soaking methods, the cleaning efficiency is greatly improved.

[0014] 2. It abandons the traditional method of using large amounts of lint-free cloths and cleaning agents, and reduces the consumption of consumables by recycling the cleaning solution, effectively saving production costs.

[0015] 3. The cleaning fluid in the circulation is filtered and impurities are removed by setting up a filter screen. The filter screen and the spray box adopt a detachable magnetic disassembly and assembly mechanism, which makes it easy to clean and replace the filter screen, ensuring the cleanliness of the cleaning fluid, and the maintenance operation is simple and convenient.

[0016] In summary, by using a circulating pump to drive the cleaning fluid circulation, the cleaning fluid sprayed from the spray head can form an impact force, which can effectively remove contaminants such as oxide layers from the surface of the dispensing valve nozzle, significantly improving cleaning efficiency compared to traditional wiping and soaking methods. By setting up a filter screen to filter and trap impurities in the circulating cleaning fluid, and using a detachable magnetic disassembly and assembly mechanism between the filter screen and the spray box, it is convenient to clean and replace the filter screen.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A rapid circulating spray washing device includes a spray washing box 1, a spray washing cover 2 covering the top of the spray washing box 1, a protrusion 10 fixedly connected to the top of the spray washing box 1, a groove 11 opened at the bottom of the spray washing cover 2, the protrusion 10 is inserted into the groove 11, and the spray washing cover 2 and the spray washing box 1 are positioned and installed by the cooperation of the protrusion 10 and the groove 11. Four slots are opened on the outer wall of the spray washing box 1, and the four slots are respectively distributed on the four sides of the spray washing cover 2. The slots allow the operator to insert their hand into the slots to remove the spray washing cover 2.

[0023] A water collection tank 3 is provided on the top of the spray cover 2 to collect the cleaning fluid. A water inlet 4 is provided through the spray cover 2, and the spray head 8 is provided through the water inlet 4. A circulation pump 5 is fixedly connected to the side wall of the spray tank 1. The circulation pump 5 is provided with an inlet and an outlet. The inlet is fixedly connected to an inlet pipe 6, and the end of the inlet pipe 6 is fixedly connected to the side wall of the spray tank 1. The outlet is fixedly connected to an outlet pipe 7. The circulation pump 5 drives the cleaning fluid to be drawn from the spray tank 1 through the inlet pipe 6 and then transported to the spray head 8 through the outlet pipe 7. A spray column 9 is fixedly connected to the inner wall of the spray tank 1. The top of the spray column 9 is fixedly connected to the spray head 8. The outlet pipe 7 passes through the spray tank 1 and the end of the outlet pipe 7 is fixedly connected to the spray column 9. The spray column 9 supports the spray head 8 and serves as a channel for transporting the cleaning fluid.

[0024] The spray washing tank 1 is equipped with a filter screen 12, which is used to filter impurities in the cleaning fluid. The filter screen 12 has a through opening, and a first sealing element 13 is fixedly connected to the inner wall of the through opening. The first sealing element 13 prevents the cleaning fluid from leaking from the gap between the filter screen 12 and the spray washing column 9. The inner wall of the first sealing element 13 abuts against the outer wall of the spray washing column 9. A second sealing element 18 is fixedly connected to the outer wall of the filter screen 12. The outer wall of the second sealing element 18 abuts against the inner wall of the spray washing tank 1. The second sealing element 18 prevents the cleaning fluid from leaking from the gap between the filter screen 12 and the inner wall of the spray washing tank 1.

[0025] Two disassembly and assembly mechanisms are provided between the spray washing box 1 and the filter screen 12.

[0026] In this invention, after the circulation pump 5 is started, it drives the cleaning liquid in the spray tank 1 to be drawn into the circulation pump 5 through the water inlet pipe 6, and then transported to the spray column 9 through the water outlet pipe 7. Finally, it is sprayed out from the spray head 8. The sprayed cleaning liquid can form an impact force on the surface of the dispensing valve nozzle to achieve the effect of wetting and removing glue. At the same time, the cleaning liquid falls back into the spray tank 1 to form a circulating flow.

[0027] The spray cover 2 is positioned and installed by inserting the protrusion 10 into the groove 11. The water collection tank 3 on its top can collect the sprayed cleaning liquid and guide it into the spray tank 1 through the water inlet 4 to ensure the circulation of the cleaning liquid.

[0028] The filter screen 12 filters and traps impurities in the circulating cleaning fluid; the first seal 13 and the second seal 18 respectively prevent the cleaning fluid from leaking from the gap between the filter screen 12 and the spray column 9 and the inner wall of the spray box 1, ensuring that the cleaning fluid circulates in a closed path.

[0029] The disassembly and assembly mechanism fixes the filter screen 12 by the attraction between the magnet 16 and the iron column 15. When the filter screen 12 needs to be cleaned or replaced, the fixing cover 17 can be directly removed, making the operation convenient.

[0030] This device uses a circulating pump 5 to drive the cleaning fluid to circulate, and the impact and soaking action of the spray head 8 removes contaminants from the nozzle. At the same time, the filtration and sealing structure ensures the cleaning effect and the stability of the device, and the detachable design makes it easy to maintain.
