[0001] The present invention relates to a spring cleaning device and a spring cleaning method. Background Art

[0002] A spring cleaning production line is a production line device specifically used for cleaning springs. It can thoroughly clean springs through multiple automated steps, removing grease, impurities, or metal chips 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 no residual impurities to avoid affecting the precision operation of equipment.

[0020] Such as Figure 1-8As shown in the figure, the spring cleaning device of the present invention includes a main spring cleaning tank 1, a spring receiving tank device 2, and a motor 3 fixed on the main spring cleaning tank 1. The main spring cleaning tank 1 is divided into a main chamber 4 and an overflow chamber 5. The spring receiving tank device 2 is placed in the main chamber 4 by a crane. The spring receiving tank device 2 includes a transmission gear set 7 docked with the motor 3 and a receiving tank assembly 8. The receiving tank assembly 8 includes a receiving tank body 9, a receiving tank door 10, a transmission shaft group 11 horizontally rotatably penetrating through the receiving tank body 9, one-way valves 12, a regulating plate 13, and an adaptive spring 14 provided on both sides of the receiving tank body 9. The transmission shaft group 11 includes an upper first transmission shaft 16 and a lower first transmission shaft 17 arranged vertically, and an upper second transmission shaft 18 and a lower second transmission shaft 19 arranged vertically. The upper first transmission shaft 16, the lower first transmission shaft 17, the upper second transmission shaft 18, and the lower second transmission shaft 19 all include a transmission shaft body 20. Stirring rods 21 are arranged at intervals on the outer wall of the transmission shaft body 20. One end of the transmission shaft body 20 is docked with the transmission gear set 7 through a coupling, and the other end is provided with a main shaft hole 22. Liquid outlet holes 23 communicating with the main shaft hole 22 are arranged at intervals on the outer wall of the stirring rod 21. The transmission shaft group 11 is used to stir the springs, so that the springs are physically separated during the cleaning process, effectively reducing the mutual entanglement of the springs and improving the uniformity of cleaning.

[0021] A receiving tank cavity 25 for placing the springs is provided in the receiving tank body 9. A receiving tank limiting groove 26 for the up and down movement of the regulating plate 13 and arranged above the transmission shaft group 11 is provided on the side wall of the receiving tank cavity 25. Receiving tank recovery seats 27 are provided on the outer walls on both sides of the receiving tank body 9 at the receiving tank limiting groove 26. A box body liquid passage is provided in the receiving tank recovery seat 27. An internal box body communication port 28 communicating with the box body liquid passage is provided on the receiving tank limiting groove 26. A main return liquid hole 29 communicating with the box body liquid passage is provided on the receiving tank recovery seat 27. The upper end of the adaptive spring 14 abuts against the upper wall of the receiving tank cavity 25 and its lower end abuts above the regulating plate 13. The receiving tank cavity 25 can be communicated with the main chamber 4 through the one-way valve 12. Cleaning liquid is introduced into the main shaft hole 22 of the stirring rod 21, and then the microbubble generator is started to inject microbubbles into the main shaft hole 22. The microbubbles make the microbubbles adhere to the surface of the springs in the receiving tank cavity 25 through the liquid outlet holes 23 of the shaft body. When the pressure of the cleaning liquid in the receiving tank cavity 25 reaches the preset value, the cleaning liquid pushes the regulating plate 13 to move upward, so that the cleaning liquid is recycled after passing through the internal box body communication port 28, the box body liquid passage, and the main return liquid hole 29. An adaptive circulating water path can be formed inside the receiving tank body 9 according to the water pressure inside the receiving tank cavity 25. By controlling the circulating flow rate of the cleaning liquid, it can be ensured that the microbubbles in the cleaning liquid flow fully around the springs, further improving the cleaning effect of the springs.

[0022] The stirring rods 21 of the first upper transmission shaft 16, the stirring rods 21 of the first lower transmission shaft 17, the stirring rods 21 of the second upper transmission shaft 18, and the stirring rods 21 of the second lower transmission shaft 19 are arranged staggeredly. During stirring, rotation can make the contact between the spring and the stirring rod 21 more sufficient, effectively improving the stirring efficiency.

[0023] The transmission gear set 7 includes a gear mounting plate 30 fixed on the outer wall of the housing 9 of the receiving box, a first gear assembly 31 rotatably arranged on the gear mounting plate 30 and butt-jointed with the end of the first lower transmission shaft 17, a second gear assembly 32 butt-jointed with the end of the first upper transmission shaft 16, a third gear assembly 33 butt-jointed with the end of the second upper transmission shaft 18, a fourth gear assembly 34 butt-jointed with the end of the second lower transmission shaft 19, and a transmission gear assembly 35. The transmission gear assembly 35 is in gear engagement with the second gear assembly 32 and the third gear assembly 33 respectively. The third gear assembly 33 is in gear engagement with the fourth gear assembly 34. The first gear assembly 31 is in gear engagement with the second gear assembly 32. The motor 3 is used to drive the first gear assembly 31 to rotate, realizing the synchronous rotation of multiple shafts, improving the transmission efficiency, ensuring the stability and consistency of each shaft. This structure is more compact, reducing the overall occupied space and being suitable for operation in a limited space.

[0024] The receiving box assembly 8 further includes a partition plate 38 stuck on the communication port 28 in the box body. The partition plate 38 is provided with liquid outlet small holes 39 arranged at intervals, effectively preventing the spring from flowing out of the communication port 28 in the box body when the adjusting plate 13 acts, and improving the safety of cleaning.

[0025] The housing 9 of the receiving box is provided with a check valve mounting hole 40 for mounting the check valve 12. The check valve mounting hole 40 is arranged close to the bottom of the receiving box limit groove 26, and can more effectively discharge the liquid in the receiving box cavity 25.

[0026] The upper wall of the receiving box cavity 25 is provided with a spring positioning groove 41 for limiting the adaptive spring 14, improving the smooth and reliable operation of the adaptive spring 14.

[0027] 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 body of the stirring rod 21 to soak the springs in the receiving box cavity 25. This temperature range can not only effectively dissolve grease and remove impurities, but also avoid the possible influence of too high temperature on the spring material. Too high temperature may damage the spring surface coating or change the metal properties.

[0028] 2. Start the motor 3, drive the drive shaft group 11 to rotate through the transmission gear set 7, so that the stirring rod 21 stirs the spring at the same time, to promote the separation of the spring and the full immersion of the cleaning liquid. The rotation speed range of the stirring rod 21 is set to 40 - 60 RPM (revolutions per minute), increasing the fluidity of the liquid and the cleaning efficiency;

[0029] 3. Start the microbubble generator (a conventional product on the market, not described here in detail), and inject bubbles with a diameter of 10 - 50 microns into the cleaning liquid in the cavity 25 of the receiving box through the main hole 22 and the liquid outlet hole 23 of the shaft body of the stirring rod 21. Bubbles in this size range can penetrate into the uneven parts of the spring surface, effectively removing fine dirt. The bubble concentration is 10^7 - 10^8 microbubbles per liter. This concentration ensures the high efficiency of microbubble cleaning without causing insufficient stirring or foam accumulation due to excessive bubbles;

[0030] 4. When the pressure in the cavity 25 of the receiving box reaches the pressure preset value of the adaptive spring 14, the cleaning liquid pushes the regulating plate 13 to move upward, so that the cleaning liquid forms a circulating water path after passing through the communication port 28 in the box body, the liquid passage in the box body, and the main liquid return hole 29. By controlling the circulating flow rate of the cleaning liquid, it can be ensured that the microbubbles in the cleaning liquid flow fully around the spring. The pressure preset 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 microbubbles, improve the cleaning effect, and will not cause deformation or damage to the spring due to excessive pressure and ensure the smooth circulation of the cleaning liquid;

[0031] 5. Inject the cleaning mixture into the main cavity 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 cavity 4 with the cavity 25 of the receiving box, making the spring cleaning more flexible and adjustable as needed.

[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention are all included in the protection scope of the present invention.
