Description

Technical Field

[0001] This utility model relates to the field of steel strip post-processing technology, and in particular to an electrostatic degreasing device for processing ultra-thin chrome-plated steel strip. Background Technology

[0002] During the rolling and handling processes, ultra-thin chrome-plated steel strips are prone to the adhesion of rolling oil, rust-preventive oil, and dust impurities. These contaminants can seriously affect the adhesion of the plating layer in subsequent chrome plating processes, leading to defects such as peeling, flaking, and pinholes. Electrolytic degreasing can efficiently remove stubborn grease and impurities from the steel strip surface through electrochemical action. Compared with traditional chemical degreasing and wiping degreasing, it is more thorough and efficient, providing a clean surface substrate for subsequent chrome plating processes.

[0003] The specific electrolysis process of ultra-thin chrome-plated steel strip is as follows: When the equipment storing the steel strip coil releases the steel strip coil into the electrolytic cell, a guide structure is needed to press the steel strip into the electrolytic cell. After the steel strip completes electrolysis in the electrolytic cell, a winding device set above the electrolytic cell winds it up. However, when the equipment storing the steel strip coil replenishes the steel coil, it is mostly done manually by passing one end of the steel strip through the bottom of the guide structure. Since the guide structure has a certain length, it is difficult and time-consuming to manually pass the steel strip through the guide structure. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems mentioned in the background art mentioned above in the prior art, and to propose an electrostatic degreasing device for processing ultra-thin chrome-plated steel strip.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An electrolytic degreasing device for processing ultra-thin chrome-plated steel strip includes a support frame, an electrolytic cell, a positive electrode plate, and a conductive pulley. The electrolytic cell is fixedly mounted at an incline on the top of the support frame. Support seats are symmetrically fixedly connected to the top of the electrolytic cell. A release roller is rotatably connected to the support seat at one end of the top of the electrolytic cell, and a take-up roller is rotatably connected to the support seat at the other end of the top of the electrolytic cell. The chrome-plated steel strip wound around the outer wall of the release roller is released into the electrolytic cell to complete electrolytic degreasing and is then wound up by the take-up roller. The electrolytic cell is provided with a pressing guide assembly between the winding roller and the release roller, which presses the chrome-plated steel strip into the electrolyte. A conductive component is provided in the middle of the electrolytic cell, which provides a stable conductive path for the ultra-thin chrome-plated steel strip passing through the electrolytic cell. The electrolytic cell is provided with a belt pulling assembly on both sides. When the release roller is used to replace the steel strip roll, the belt pulling assembly helps the steel strip roll pass under the pressing guide assembly.

[0006] Optionally, the pressing guide assembly includes a lifting assembly, a common plate, and a guide U-frame. The guide U-frame is bolted to the top of the electrolytic cell, and a lifting motor is fixedly connected to the top of the guide U-frame.

[0007] Optionally, a lifting screw is fixedly connected to the output end of the lifting motor, an extension rod is threaded into the outer wall of the lifting screw, a common plate is fixedly connected to the bottom of the extension rod, and edge guide wheels are rotatably connected to both ends of the common plate.

[0008] Optionally, the conductive component includes a positive electrode plate, a negative electrode post, and a conductive pulley; an extension cell is fixedly connected to the side of the electrolytic cell; and a U-shaped frame is fixedly connected to the top of the extension cell.

[0009] Optionally, the U-shaped frame is fixedly connected to a positive electrode plate, the negative electrode post is screwed into an extension rod, the bottom of the negative electrode post is in contact with the shaft of the conductive pulley, and the conductive pulley is rotatably connected to a common plate.

[0010] Optionally, the pull belt assembly includes a pull rope, a pull block, and plastic bolts. One end of the pull rope is fixedly connected to the take-up roller shaft, and the other end of the pull rope is fixedly connected to the pull block. A transverse T-groove is provided on the side of the common plate.

[0011] Optionally, the pulling block is inserted into the horizontal T-groove, the pulling block has an insertion port on its side, and a plastic bolt is screwed into the top of the pulling block.

[0012] Compared with the prior art, the present invention has the following advantages: 1. This device, by setting up a belt pulling assembly, allows the pulling block to be connected to the end of the steel strip when replenishing steel coils. The rotation of the take-up roller drives the pulling rope to pull the steel strip through the guide structure. This eliminates the need for manual insertion into the electrolytic cell or threading the strip from the bottom of the guide structure, significantly reducing the difficulty of the threading operation, reducing manpower consumption and operation time, and significantly improving the overall efficiency of steel strip replacement and degreasing processing, thus meeting the needs of industrial continuous production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-4 An electrolytic degreasing device for processing ultra-thin chrome-plated steel strip includes a support frame 5, an electrolytic cell 1, a positive electrode plate 31, and a conductive pulley 8. The electrolytic cell 1 is inclinedly welded to the top of the support frame 5. Support seats 4 are symmetrically bolted to the top of the electrolytic cell 1. There are four support seats 4 in total. A release roller 10 is rotatably connected to the support seat 4 at one end of the top of the electrolytic cell 1 by a pin shaft. A take-up roller 7 is rotatably connected to the support seat 4 at the other end of the top of the electrolytic cell 1 by a pin shaft. The chrome-plated steel strip wrapped around the outer wall of the release roller 10 is released into the electrolytic cell 1 to complete electrolytic degreasing and is then taken up by the take-up roller 7.

[0020] In fact, the support base 4 consists of a base body and a top cover. The top cover is fixed to the top of the base body with bolts. The shafts of the release roller 10 and the take-up roller 7 are inserted into the circular cavity between the base body and the top cover. The top cover can be removed from the base body to facilitate the replacement of the steel strip on the release roller 10 and the take-up roller 7. The release roller 10 and the take-up roller 7 are composed of a smooth roller body and edge covers. The two edge covers are screwed into the ends of the outer wall of the smooth roller body.

[0021] An insertion guide assembly is provided between the take-up roller 7 and the release roller 10 in the electrolytic cell 1. The insertion guide assembly presses the chrome-plated steel strip into the electrolyte. The insertion guide assembly includes a lifting assembly, a common plate 9, and a guide U-frame 11. The guide U-frame 11 is bolted to the top of the electrolytic cell 1. A lifting motor 13 is bolted to the top of the guide U-frame 11. A lifting screw 12 is fixedly connected to the output end of the lifting motor 13. An extension rod 14 is threaded into the outer wall of the lifting screw 12. The side wall of the extension rod 14 is attached to the side wall of the guide U-frame 11. The common plate 9 is fixedly welded to the bottom of the extension rod 14. Both ends of the common plate 9 are rotatably connected to edge guide wheels 92 by pins.

[0022] A conductive component is located in the middle of electrolytic cell 1, providing a stable conductive path for the ultra-thin chrome-plated steel strip passing through electrolytic cell 1. The conductive component includes a positive electrode plate 31, a negative electrode post 15, and a conductive pulley 8. An extension cell 2 is fixedly connected to the side of electrolytic cell 1, and electrolytic cell 1 and extension cell 2 are integrated. A U-shaped frame 3 is bolted to the top of extension cell 2, and the positive electrode plate 31 is bolted to the U-shaped frame 3. The negative electrode post 15 is threaded onto the extension rod 14, and the bottom of the negative electrode post 15 contacts the rotating shaft of the conductive pulley 8. The conductive pulley 8 is rotatably connected to a common plate 9 by a pin. The positive electrode plate 31 is made of titanium-based ruthenium-iridium coated electrode. Figure 1 A terminal post is provided on the top of the positive electrode plate 31. The positive electrode plate 31 and the negative electrode post 15 are connected to an external power source. The conductive pulley 8 is energized by continuous contact with the metal belt.

[0023] Electrolytic cell 1 has belt-pulling assemblies on both sides. When the release roller 10 changes the steel strip roll, the auxiliary steel strip roll passes under the pressing guide assembly. The belt-pulling assembly includes a pull rope 18, a pull block 17, and plastic bolts 16. One end of the pull rope 18 is fixedly connected to the shaft of the take-up roller 7. (Refer to...) Figure 2 Both ends of the take-up roller 7 are also equipped with retaining rings, and one end of the pull rope 18 is fixed to the outside of the retaining ring, so that the winding of the rope and the take-up operation of the take-up roller 7 are carried out independently. The other end of the pull rope 18 is fixedly connected to the pull block 17. A horizontal T-groove 91 is opened on the side of the common plate 9, and the pull block 17 is inserted into the horizontal T-groove 91. An insertion port 171 is opened on the side of the pull block 17, and a plastic bolt 16 is screwed into the top of the pull block 17. In order to avoid the electrolyte in the electrolytic cell 1 from corroding the various components, the common plate 9 and the extension rod 14 are made of polytetrafluoroethylene. In addition, in order to avoid electric shock, the take-up roller 7 and the release roller 10 are also made of polytetrafluoroethylene. Finally, in order to ensure the electrolytic degreasing effect of the steel strip, the speed of the take-up motor 6 needs to be set relatively slowly.

[0024] The specific implementation steps and principles of this utility model are as follows: When installing the steel strip onto the entire electrolytic cell 1, start the lifting motor 13. The lifting motor 13 drives the common plate 9 at the bottom of the extension rod 14 to move to the limit position through the lifting screw 12. Manually insert the pulling block 17 into the transverse T-groove 91. Since the electrolytic cell 1 is inclined, the common plate 9 is also inclined. The pulling block 17 will slide along the transverse T-groove 91 to the side of the release roller 10. Insert a roll of steel strip on the release roller 10 into the two insertion ports 171, then tighten the two plastic bolts 16, start the winding motor 6, and the winding motor 6 drives the winding roller 7 to rotate, winding the pulling rope 18. The pulling rope 18 passes through the pulling block 17 and pulls one end of the steel strip to the side of the winding roller 7. Loosen the two plastic bolts 16, and finally fix one end of the steel strip to the outer wall of the winding roller 7.

[0025] Finally, the lifting motor 13 is started, which drives the two edge guide wheels 92 and the conductive pulley 8 on the common plate 9 to sink below the electrolyte surface.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
