Description

Technical Field

[0001] This utility model relates to the technical field of wire cleaning device for metal smelting and rolling products, and more specifically, it relates to a wire cleaning device for metal smelting and rolling products. Background Technology

[0002] In existing technologies, the design and function of wire cleaning equipment for metal smelting and rolling products may have some limitations, which may affect its environmental friendliness and operational efficiency.

[0003] First, traditional wire cleaning equipment may have a relatively simple structure. This design may work well in the initial use, but over time, such equipment may not be able to recycle the cleaning water. During the cleaning process, a large amount of cleaning water is used to remove dirt and oxides from the surface of the wire, but this cleaning water is often directly discharged after the cleaning task is completed. This not only wastes water resources, but may also pollute the environment. In addition, frequent replacement of cleaning water will increase operating costs and reduce the economic benefits of the cleaning equipment.

[0004] Secondly, some existing wire cleaning devices require the connection of multiple pipes during operation, such as water inlet pipes, drain pipes, and spray pipes. However, the connection operation between pipes in the existing technology is usually cumbersome and complicated, requiring the use of special tools and skills. This undoubtedly increases the difficulty and time of operation. In addition, the cumbersome connection and disassembly operations may also damage the pipes and affect the service life of the cleaning device.

[0005] In addition, although some existing wire cleaning devices use quick-connect pipe designs, these quick-connect structures are often relatively simple. In pursuit of quick connection, they may sacrifice the sealing of the connection. Leaks at the connection will lead to the loss of cleaning water, reduce the cleaning effect, and increase the risk of water waste and environmental pollution. Furthermore, leaks may also make the ground around the cleaning device slippery, increasing workplace safety hazards. Summary of the Invention

The machine tool 1 is characterized by having a cleaning device mounted on it, a conveying pipe 2 on its outer side, and a connecting device connected to one end of the conveying pipe 2. The connecting device includes a mating sleeve 3, an adapter frame 4, a sleeve 5, a guide frame 6, a limiting plate 7, a plug-in mechanism, a spring 8, and a guide groove 9. The mating sleeve 3 is movably fitted onto the outer side of the sleeve 5, the adapter frame 4 is fixedly installed inside the mating sleeve 3, the sleeve 5 is detachably fitted onto the outer side of the conveying pipe 2, the guide frame 6 is movably installed in the guide groove 9, the limiting plate 7 is movably installed on the outer side of the sleeve 5 via threads, the spring 8 is movably installed on one side of the limiting plate 7, and the guide groove 9 is formed in the adapter frame 6. Inside the frame 4 and outside the conveying pipe 2, there is a leak-proof mechanism. The leak-proof mechanism includes an adapter groove 10, an arc groove 11, an adapter rod 12, an adapter sleeve 13, a threaded sleeve 14, a sealing plate 15, a sealing groove 16, a through groove 17, and an adapter plate 18. The adapter groove 10 is opened at one end of the arc groove 11, and the arc groove 11 is opened on the adapter sleeve 13. The adapter rod 12 is fixedly connected to one side of the mating sleeve 3. The adapter sleeve 13 is movably set on the outside of the sleeve 5. The threaded sleeve 14 is detachably installed on the outside of the sleeve 5 by threads. The through groove 17 penetrates the side wall of the sleeve 5. The adapter plate 18 is fixedly connected to the adapter rod 12. The sealing plate 15 is set on the outside of the conveying pipe 2, and the sealing groove 16 is opened in the sleeve 5.

[0029] The machine tool 1 is equipped with a motor 19, and the output end of the motor 19 is equipped with a take-up roller 20. The other side of the machine tool 1 is equipped with a conveyor roller 21, which is movably arranged inside the machine tool 1.

[0030] The insertion mechanism includes an insertion rod 22 and an insertion slot 23. The insertion slot 23 is located on the outside of the conveying pipe 2. One end of the insertion rod 22 is inserted into the insertion slot 23, and the other end of the insertion rod 22 is fixedly connected to the guide frame 6. The other end of the spring 8 is fixedly connected to the insertion rod 22.

[0031] A push spring 24 is sleeved on the outside of the adapter rod 12, and one end of the push spring 24 is in contact with the adapter plate 18.

[0032] In this embodiment, when a pipe connection is required, the adapter 13 is first rotated in the corresponding direction. The adapter 13 will drive the arc groove 11 and the adapter groove 10 to move. When the adapter groove 10 and the adapter rod 12 are concentric, the rotation stops. Then, the mating sleeve 3 is pushed upward. The adapter plate 18 and the adapter rod 12 on one side of the mating sleeve 3 will pass through the adapter groove 10, and the mating sleeve 3 will cooperate with the adapter 13 to compress the push spring 24. Then, the mating sleeve 3 will drive the adapter frame 4 to move, and then the adapter frame 4 will pass through... The guide groove 9 drives the guide frame 6 to move outward, and then the guide frame 6 drives the plug rod 22 to move outward. At the same time, the spring 8 pushes the plug rod 22 to move in the through groove 17. When one end of the plug rod 22 is flush with the inner wall of the sleeve 5, the adapter plate 18 just passes through the adapter groove 10. Then, the adapter 13 is rotated, and the adapter 13 drives the arc groove 11 and the adapter groove 10 to move, so that the adapter rod 12 enters the arc groove 11, and the adapter plate 18 is stuck above the adapter 13. Then, the adapter 13 and the adapter plate 10 are released. Fitting sleeve 3 is then inserted into sleeve 5, and adapter sleeve 13 is rotated again, causing adapter rod 12 and adapter plate 18 to move to a position concentric with adapter groove 10. Then, push spring 24 pushes fitting sleeve 3 to reset, causing adapter rod 12 to pull adapter plate 18 out of adapter groove 10. Fitting sleeve 3 then resets adapter frame 4 and guide groove 9, causing guide groove 9 to reset guide frame 6. Guide frame 6 then moves insertion rod 22 inward and gradually inserts it into insertion groove. In step 23, the plug rod 22 moves in the through groove 17 and compresses the spring 8. Then, the plug rod 22 drives the delivery pipe 2 to be pressed inward through the plug groove 23, so that the sealing plate 15 set on the outside of the delivery pipe 2 is fully inserted into the sealing groove 16 opened on the inside of the sleeve 5, thereby ensuring the sealing performance of the pipe connection. Then, the adapter 13 is rotated so that the adapter rod 12 abuts against the adapter plate 18, thereby forming a stable support for the mating sleeve 3, thus realizing a fast and stable connection of the pipe.

[0033] Please see Figure 1-3 As one embodiment of the cleaning device: the cleaning device includes a liquid storage tank 25, a cleaning pipe 26, a delivery pump 27, and a spray pipe 28. The liquid storage tank 25 is located on one side of the machine tool 1, the delivery pump 27 is installed on one side of the liquid storage tank 25, and the spray pipe 28 is detachably installed on one side of the cleaning pipe 26. The input end of the delivery pump 27 is connected to the output end of the liquid storage tank 25 through the delivery pipe 2, and the output end of the delivery pump 27 is connected to the cleaning pipe 26 through the delivery pipe 2.

[0034] The machine tool 1 has a recovery bin 29 on its inner side.

[0035] A recovery pump 30 is provided on one side of the delivery pump 27. The input end of the recovery pump 30 is connected to the bottom end of the recovery chamber 29 through the delivery pipe 2, and the output end of the recovery pump 30 is connected to the top end of the liquid storage tank 25 through the delivery pipe 2.

[0036] The machine tool 1 is provided with a protective compartment 31 on its outer side, and the protective compartment 31 can be detachably installed on top of the machine tool 1.

[0037] More specifically, when the equipment is needed, the conveyor roller 21 with the wire wound on it is movably installed in the corresponding position inside the machine tool 1, and one end of the wire is passed through multiple protective chambers 31 and wound onto the take-up roller 20. Then, the conveyor pump 27 is turned on, and the conveyor pump 27 draws out the cleaning water stored in the storage tank 25 through the conveyor pipe 2 connected to the input end. Then, the drawn cleaning water is delivered to each cleaning pipe 26 through the conveyor pipe 2 connected to the output end of the conveyor pump 27, and then sprayed out through the spray pipe 28 set on one side of the cleaning pipe 26 to clean the wire. The protective chambers 31 are set to prevent the cleaning water from being sprayed out. The washing water is sprayed onto the outside and the ground. Then, the motor 19 is turned on, which drives the take-up roller 20 to rotate and take up the cleaned wire. At the same time, the conveyor roller 21 rotates to release the uncleaned wire. The sprayed washing water is then collected in the recycling bin 29. The recycling pump 30 is then turned on, and the recycling pump 30 extracts the sprayed washing water stored in the recycling bin 29 through the conveyor pipe 2 connected to the input end. The extracted washing water is then transported back to the storage tank 25 through the conveyor pipe 2 connected to the output end of the recycling pump 30, thus realizing the recycling and reuse of the washing water.

[0038] In summary, during the use or operation of the overall equipment: when pipe connections are required, first rotate the adapter 13 in the corresponding direction. The adapter 13 will move the arc groove 11 and the adapter groove 10. Rotation stops when the adapter groove 10 and the adapter rod 12 are concentric. Then, push the mating sleeve 3 upwards. The adapter plate 18 and the adapter rod 12 on one side of the mating sleeve 3 will pass through the adapter groove 10, and the mating sleeve 3 will cooperate with the adapter 13 to press against the push spring 24. Then, the mating sleeve 3 will move the adapter frame 4. The adapter 4 moves the guide 6 outward via the guide groove 9. The guide 6 then moves the plug rod 22 outward, while the spring 8 pushes the plug rod 22 through the through groove 17. When one end of the plug rod 22 is flush with the inner wall of the sleeve 5, the adapter plate 18 passes through the adapter groove 10. Then, the adapter 13 is rotated, causing the arc groove 11 and the adapter groove 10 to move, allowing the adapter rod 12 to enter the arc groove 11, and the adapter plate 18 to be secured above the adapter 13. Finally, the adapter is released. The sleeve 13 and the mating sleeve 3 are then inserted, and the conveying pipe 2 is inserted into the sleeve 5. The mating sleeve 13 is then rotated again, causing the mating rod 12 and the mating plate 18 to move again to a position concentric with the mating groove 10. Then, the push spring 24 pushes the mating sleeve 3 to reset, causing the mating rod 12 to pull the mating plate 18 out of the mating groove 10. The mating sleeve 3 then drives the mating frame 4 and the guide groove 9 to reset, causing the guide groove 9 to drive the guide frame 6 to reset. The guide frame 6 then drives the insertion rod 22 to move inward and gradually insert it into the insertion groove. In the groove 23, the insertion rod 22 moves in the through groove 17 and compresses the spring 8. Then, the insertion rod 22 drives the delivery pipe 2 to be pressed inward through the insertion groove 23, so that the sealing plate 15 set on the outside of the delivery pipe 2 is fully inserted into the sealing groove 16 opened on the inside of the sleeve 5, thereby ensuring the sealing performance of the pipe connection. Then, the adapter 13 is rotated so that the adapter rod 12 abuts against the adapter plate 18, thereby forming a stable support for the mating sleeve 3, thus realizing a fast and stable connection of the pipe.

[0039] When the equipment is needed, the conveyor roller 21 with the wire wound on it is movably installed in the corresponding position inside the machine tool 1, and one end of the wire is passed through multiple protective chambers 31 and wound onto the take-up roller 20. Then, the conveyor pump 27 is turned on, and the conveyor pump 27 draws out the cleaning water stored in the storage tank 25 through the conveyor pipe 2 connected to the input end. Then, the drawn cleaning water is delivered to each cleaning pipe 26 through the conveyor pipe 2 connected to the output end of the conveyor pump 27, and then sprayed out through the spray pipe 28 set on one side of the cleaning pipe 26 to clean the wire. The protective chambers 31 are set to prevent the cleaning water from being washed away. The cleaning water is sprayed onto the outside environment and the ground. Then, the motor 19 is turned on, which drives the take-up roller 20 to rotate and take up the cleaned wire. At the same time, the conveyor roller 21 rotates to release the uncleaned wire. The sprayed cleaning water will then accumulate in the recovery bin 29. Then, the recovery pump 30 is turned on, and the recovery pump 30 will extract the sprayed cleaning water stored in the recovery bin 29 through the conveyor pipe 2 connected to the input end. Then, the extracted cleaning water will be transported back to the storage tank 25 through the conveyor pipe 2 connected to the output end of the recovery pump 30, thereby realizing the recycling of the cleaning water.
