[0002] Austenitic stainless steel strip refers to stainless steel with an austenitic structure at room temperature. It is non-magnetic and has high toughness and plasticity. However, its strength is relatively low and it can only be strengthened through cold working, thus having good machinability. Therefore, it is widely used in industry, furniture decoration industry, and food and medical industry.

[0003] In the related art, a surface treatment method for an austenitic stainless steel strip includes the following steps: using an ultrasonic cleaner filled with deionized water to clean the surface of the strip to remove oil stains, then treating the strip with an ethanol solution, and then dehydrating and drying the strip after the ethanol solution treatment through an air drying device.

[0004] Regarding the above-mentioned related technologies, if the stainless steel strip is simply dehydrated and dried using air drying equipment such as fans, a large amount of water stains and dirt will easily remain on the surface of the stainless steel strip, affecting the quality of the final stainless steel strip product, so it needs to be improved.

[0036] Reference Figure 2 and Figure 3 The central shaft 23 is rotatably connected to the interior of each set of mounting frames 22. In this embodiment, the electric heating element 24 is a heating wire to provide auxiliary heating for the central shaft 23. An absorption tube 25 is fixedly sleeved on each set of central shafts 23. Specifically, the absorption tube 25 can be a sponge with good water absorption.

The cleaning motor 54 is fixedly connected to the end of the mounting frame 22, and the output end of the cleaning motor 54 is transmission-connected to the end of the cleaning screw 53 to drive the cleaning screw 53 to rotate. The moving block 52 is slidably connected to the mounting frame 22, and the cleaning screw 53 passes through the moving block 52. The cleaning screw 53 is threadedly connected to the moving block 52, thereby driving the moving block 52 to move along the length direction of the central axis 23.

[0039] Reference Figure 2 and Figure 3 The cleaning ring plate 51 is fixedly connected to the side wall of the moving block 52 facing the central shaft 23, and the central shaft 23 passes through the cleaning ring plate 51. The side walls on both sides of the cleaning ring plate 51 in the thickness direction are recessed toward the hole in the center of the cleaning ring plate 51. A gap is left between the inner peripheral wall of the cleaning ring plate 51 and the outer peripheral wall of the central shaft 23 for the compressed absorption cylinder 25 to pass through. This allows the cleaning ring plate 51 to squeeze the absorption cylinder 25 into the hole inside the cleaning ring plate 51 and scrape and clean the liquid absorbed by the absorption cylinder 25.

[0040] Reference Figure 2 and Figure 3 A drive disc 231 is fixedly mounted on the end of the central shaft 23. Several sets of drive notches 2311 are formed through the sidewall of the drive disc 231, and all of the drive notches 2311 are spaced apart along the circumference of the drive disc 231. A central gear 221 is rotatably connected to the inner sidewall of the mounting frame 22 via a rotating shaft. The central gear 221 is located between the central shaft 23 and the cleaning screw 53. A toggle lever 222 is fixedly connected to the central gear 221. The end of the toggle lever 222, which is distal to the central gear 221, slides into any of the drive notches 2311, thereby driving the drive disc 231 and the central shaft 23 to rotate the absorption cylinder 25.

[0041] Reference Figure 2 and Figure 3 The end of the cleaning screw 53 is fixedly sleeved with a one-way bearing 531, and a directional gear 532 is fixedly adjusted on the outer peripheral wall of the one-way bearing 531, so that the cleaning screw 53 can only drive the directional gear 532 to rotate in one direction through the one-way bearing 531, and the directional gear 532 is engaged with the center gear 221.

[0042] Reference Figure 2 and Figure 3 The mounting frame 22 is connected to a constricting assembly 6 for constricting and squeezing the absorbent tube 25. The constricting assembly 6 comprises a constricting cord 61, a pulling block 62, and a driving member 63. Specifically, the constricting cord 61 is a highly elastic elastic cord that is fixedly inserted into the absorbent tube 25. The constricting cord 61 extends spirally along the length of the absorbent tube 25, with both ends of the constricting cord 61 passing through the ends of the central shaft 23.

[0043] Reference Figure 2 and Figure 3 The traction blocks 62 are slidably mounted on the outer wall of the mounting frame 22 via anti-slip blocks, and are located at both ends of the central shaft 23. One end of the tie rope 61 passes through the end wall at one end of the central shaft 23 in the longitudinal direction and is adhesively connected to one set of traction blocks 62; the other end of the tie rope 61 passes through the end wall at the other end of the central shaft 23 and is adhesively connected to the other set of traction blocks 62.

The driving member 63 includes a traction screw 631, a rotating screw sleeve 632, a transmission gear 633, an extension shaft 634 and a driving gear 635; the traction screw 631 is integrally formed at the end of each group of traction blocks 62 away from the central axis 23. The rotating screw sleeve 632 is rotatably connected to the outer wall of the mounting frame 22. In this embodiment, the traction screw 631, the rotating screw sleeve 632, the transmission gear 633, the extension shaft 634 and the driving gear 635 are respectively arranged in a one-to-one correspondence. The rotating screw sleeve 632 is threadedly connected to the corresponding traction screw 631, and the transmission gear 633 is integrally formed on the outer peripheral wall of the corresponding rotating screw sleeve 632.

[0045] Reference Figure 2 and Figure 3 Extension shafts 634 are integrally formed at both ends of the cleaning screw 53 in the longitudinal direction. One set of extension shafts 634 is drivingly connected to the output end of the cleaning motor 54, and a drive gear 635 is fixedly sleeved on each set of extension shafts 634. Each set of drive gears 635 meshes with the corresponding transmission gear 633 through an idler gear. Therefore, the rotation of the cleaning screw 53 drives the rotating screw sleeve 632 to rotate, and drives the traction screw 631 to move the traction block 62 and the tie rope 61, thereby tightening and loosening the tie rope 61.

[0046] Reference Figure 1 and Figure 4 The drying assembly 3 includes a closed hood 31, an air induction member 32, and a heating member 33. The closed hood 31 is fixedly mounted on the frame 1, and the closed hood 31 and the mounting frame 22 are arranged in sequence along the conveying direction of the steel strip body 10. Passageways 311 are formed through the end walls of the closed hood 31 at both ends of the length direction to allow the steel strip body 10 to pass through. An air outlet 312 is formed through the top of the closed hood 31 to allow the gas inside the closed hood 31 to be discharged.

[0047] Reference Figure 1 and Figure 4 In this embodiment, the air inducing members 32 are fans, and the heating members 33 are heating wires. The air inducing members 32 are fixedly mounted within holes on the widthwise sidewalls of the enclosure 31 to direct external air toward the sidewalls of the steel strip body 10. The heating members 33 are fixedly connected to the air inducing members 32 on both sides of the enclosure 31 to assist in heating and drying the air surrounding the air inducing members 32, thereby facilitating the air inducing members 32 to direct the dry, warm airflow toward the steel strip body 10.

[0048] Reference Figure 1 and Figure 4The detection assembly 4 includes an extension tube 41, an electrically controlled valve 42, a water detector 43, and a control unit 44. The extension tubes 41 are mounted on the side wall of the enclosure 31 facing away from the mounting frame 22, and are located on opposite sides of the width of the steel strip body 10. An electrically controlled valve 42 is mounted on each set of extension tubes 41 to control the connection between the corresponding extension tube 41 and the enclosure 31. A vent 411 is formed through the side wall of each set of extension tubes 41 facing the steel strip body 10, and is located on the side of the electrically controlled valve 42 facing away from the enclosure 31.

[0049] Reference Figure 1 and Figure 4 In this embodiment, the water measuring element 43 is an infrared moisture meter, the control element 44 is a single-chip microcomputer controller, and both the water measuring element 43 and the electrically controlled valve 42 are electrically connected to the control element 44. The water measuring element 43 is fixedly mounted on the side wall of the sealing cover 31 facing the extension tube 41 via a bracket. The water measuring element 43 is relatively distributed on both sides of the steel strip body 10 in the width direction to measure the moisture data on the surface of the steel strip body 10.

[0050] Reference Figure 1 and Figure 4 The control component 44 is fixedly installed on the frame 1. The control component 44 receives the moisture data sent by the water measuring component 43, and compares the received moisture data with the moisture value pre-stored in the control component 44. When the moisture data is higher than the preset moisture value, the control component 44 controls the electric control valve 42 to open, so that the extension tube 41 and the closing cover 31 are connected to each other, and the steel strip body 10 is dried again through the vent 411.

[0051] The implementation principle of the surface treatment equipment for austenitic stainless steel strip in the embodiment of the present application is as follows: The moving roller group 12 drives the steel belt body 10 to move on the supporting roller 11 of the machine body. During the movement of the steel belt body 10, the output end of the rotating motor 26 drives the rotating shaft 21 to drive the installation frame 22 and the absorption cylinder 25 to rotate. The rotating absorption cylinder 25 is attached to the side wall of the steel belt body 10 and absorbs the liquid attached to the surface of the steel belt body 10.

[0052] The moving steel strip body 10 passes through the absorption tube 25 to wipe the surface liquid and then enters the interior of the closed cover 31; the heating element 33 and the air-inducing element 32 blow hot air to the steel strip body 10 passing through the closed cover 31 to dry the surface of the steel strip body 10, further reducing the moisture content on the surface of the steel strip body 10.

[0053] The moving steel strip body 10 passes through the water measuring component 43, which uses infrared rays to measure the moisture data on the surface of the steel strip body 10 in real time. When the real-time measured moisture data is higher than the preset value inside the control component 44, the control component 44 controls the electric control valve 42 to open, so that the extension tube 41 and the closing cover 31 are interconnected, and the steel strip body 10 is dried again through the ventilation port 411, thereby achieving high-quality and efficient drying of the stainless steel strip and improving the final quality of the stainless steel strip.

[0054] The present application also discloses a surface treatment method for an austenitic stainless steel strip, comprising the following steps: Absorption: The moving roller group 12 moves the steel strip body 10, and the absorption component 2 absorbs the liquid attached to the surface of the steel strip body 10; Drying: The drying component 3 dries the surface of the steel strip body 10; Detection: The detection component 4 measures the moisture data on the surface of the steel strip body 10 in real time, and when there is too much moisture on the surface of the steel strip body 10, the drying component 3 is used to dry the steel strip body 10 again.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
