[0002] The spring cleaning line is a kind of assembly line equipment specially used for cleaning springs. It can thoroughly clean the springs through multiple automated steps to remove grease, impurities or metal debris attached during the production process. In the fields of high-end manufacturing, precision equipment, new energy and aerospace, the cleaning requirements for springs are more stringent to ensure that there are no residual impurities to avoid affecting the precision operation of the equipment. The traditional spring cleaning line cannot be cleaned individually due to the easy entanglement of the spring structure, which affects the efficiency and cleaning effect.

[0014] The receiving box body 9 is provided with a receiving box cavity 25 for spring placement, the side wall of the receiving box cavity 25 is provided with a receiving box limit groove 26 for the up and down movement of the adjustment plate 13 and arranged above the transmission shaft group 11, the outer walls on both sides of the receiving box body 9 are provided with a receiving box recovery seat 27 at the receiving box limit groove 26, the receiving box recovery seat 27 is provided with a box body liquid flow channel, the receiving box limit groove 26 is provided with a box body connecting port 28 communicating with the box body liquid flow channel, the receiving box recovery seat 27 is provided with a main liquid return hole 29 communicating with the box body liquid flow channel, the upper end of the adaptive spring 14 is against the upper wall of the receiving box cavity 25 and the lower end thereof is against above the adjustment plate 13, the receiving box cavity 25 can be connected with the main cavity 4 through the one-way valve 12, and the cleaning liquid is introduced into the main hole 22 of the shaft body of the stirring rod 21, and then the microbubble generator is started to inject microbubbles into the main hole 22 of the shaft body. The microbubbles are attached to the spring surface of the receiving box cavity 25 through the shaft body outlet hole 23. When the cleaning liquid pressure in the receiving box cavity 25 reaches a preset value, the cleaning liquid pushes the adjustment plate 13 to move upward so that the cleaning liquid passes through the connecting port 28 in the box body, the box body liquid channel and the main return liquid hole 29 for recycling. The inside of the receiving box body 9 can form an adaptive circulating water circuit according to the water pressure inside the receiving box cavity 25. The circulation flow rate of the cleaning liquid can be controlled to ensure that the microbubbles in the cleaning liquid fully flow around the spring, thereby further improving the cleaning effect of the spring.

[0015] The stirring rod 21 of the first upper transmission shaft 16 and the stirring rod 21 of the first lower transmission shaft 17, the stirring rod 21 of the second upper transmission shaft 18 and the stirring rod 21 of the second lower transmission shaft 19 are all arranged alternately. During stirring, the spring and the stirring rod 21 can be rotated to make the contact more complete, thereby effectively improving the stirring efficiency.

[0016] The transmission gear set 7 includes a gear mounting plate 30 fixed on the outer wall of the receiving box body 9, a first gear assembly 31 rotatably arranged on the gear mounting plate 30 and connected to the end of the first lower transmission shaft 17, a second gear assembly 32 connected to the end of the first upper transmission shaft 16, a third gear assembly 33 connected to the end of the second upper transmission shaft 18, a fourth gear assembly 34 connected to the end of the second lower transmission shaft 19, and a transmission gear assembly 35.

The structure is more compact, reduces the overall occupied space, and is suitable for operation in a limited space.

[0017] The receiving box assembly 8 also includes a partition 38 stuck on the connecting port 28 in the box body. The partition 38 is provided with liquid outlet holes 39 arranged at intervals, which effectively prevents the spring from flowing out of the connecting port 28 in the box body when the adjustment plate 13 is in motion, thereby improving the safety of cleaning.

[0018] The receiving box body 9 is provided with a one-way valve installation hole 40 for installing the one-way valve 12. The one-way valve installation hole 40 is arranged close to the bottom of the receiving box limiting groove 26, which can more effectively discharge the liquid in the receiving box cavity 25.

[0019] The upper wall of the receiving box cavity 25 is provided with a spring positioning groove 41 for limiting the adaptive spring 14 , thereby improving the stability and reliability of the action of the adaptive spring 14 .

[0020] A spring cleaning method, the specific steps are as follows: 1. The spring cleaning liquid with a temperature between 45°C and 65°C enters the receiving box cavity 25 through the main hole 22 of the shaft of the stirring rod 21 to soak the spring in the receiving box cavity 25. This temperature range can effectively dissolve grease and remove impurities, while also avoiding the influence of excessively high temperature on the spring material, which may damage the surface coating of the spring or change the metal properties; 2. Start the motor 3, and drive the transmission shaft group 11 to rotate through the transmission gear group 7, so that the stirring rod 21 stirs the spring at the same time to facilitate the separation of the spring and the full immersion of the cleaning liquid. The speed range of the stirring rod 21 is set to 40-60RPM (revolutions per minute) to increase the fluidity and cleaning efficiency of the liquid; 3. Start the microbubble generator (a conventional product on the market, which will not be described here), and inject bubbles with a diameter of 10-50 microns into the cleaning liquid in the receiving box cavity 25 through the main hole 22 and the liquid outlet hole 23 of the shaft of the stirring rod 21. Bubbles in this size range can penetrate into the concave and convex parts of the surface of the spring and effectively remove fine dirt. The bubble concentration is 10^7-10^8 microbubbles per liter, which ensures the high efficiency of microbubble cleaning without insufficient stirring or foam accumulation due to excessive bubbles; 4. When the pressure of the receiving box cavity 25 reaches the preset pressure value of the adaptive spring 14, the cleaning liquid pushes the adjustment plate 13 upward, so that the cleaning liquid forms a circulating water path through the box body connecting port 28, the box body liquid channel, and the main liquid return hole 29. The circulating flow rate of the cleaning liquid can be controlled to ensure that the microbubbles in the cleaning liquid flow fully around the spring. The preset pressure value range of the adaptive spring 14 is between 0.3 MPa and 0.5 MPa, which can ensure the appropriate pressure of the cleaning liquid on the spring, enhance the adhesion of the microbubbles, improve the cleaning effect, and prevent the spring from being deformed or damaged due to excessive pressure, and ensure smooth circulation of the cleaning liquid; 5. Inject the cleaning mixture into the main chamber 4 of the main spring cleaning box 1. When the spring needs to be mixed and cleaned, open the one-way valve 12 to connect the main chamber 4 with the receiving box chamber 25, so that the spring cleaning is more flexible and can be adjusted at any time according to needs.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the protection scope of the present invention.
