Description

Technical Field

[0001] This utility model relates to the field of degreasing technology for cold-rolled strip steel, and in particular to a degreasing and debinding device for cold-rolled strip steel. Background Technology

[0002] During the rolling process of cold-rolled strip steel, lubricants are used, which form an oil film on the strip surface. This oil film decomposes and carburizes during annealing, forming residues that affect the strip steel's composition and surface cleanliness. Furthermore, oil contamination can also affect subsequent processing, such as coating adhesion. In addition, with increasing demands for the quality of cold-rolled strip steel, traditional simple cleaning methods are no longer sufficient. To address these issues, improve strip steel quality and production efficiency, and adapt to large-scale industrial production, degreasing and oil removal devices for cold-rolled strip steel have been developed.

[0003] In the existing technology, some devices can only degrease one side of the cold-rolled strip, and the other side of the cold-rolled strip needs to be turned over to degrease. This results in long degreasing time and low efficiency for the workers. Utility Model Content

[0004] The present invention proposes a degreasing and oil removal device for cold-rolled strip steel, which aims to improve the problem of long degreasing time and low efficiency of some existing devices for cold-rolled strip steel.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A degreasing and oil removal device for cold-rolled strip steel includes a housing. Two double-headed cylinders are fixedly connected to the rear side of the housing. Each output end of a double-headed cylinder is fixedly connected to a connecting rod. A placement plate is fixedly connected to the outside of the housing. A motor is fixedly connected to the top of the placement plate. A connecting shaft is rotatably connected to the inner wall of the connecting rod. A chuck is fixedly connected to the outside of the connecting shaft. Two of the chucks are movably connected to a take-up shaft, and the other two chucks are movably connected to a release shaft. A drive wheel is fixedly connected to the outside of one connecting shaft, and a driven wheel is fixedly connected to the outside of the other connecting shaft. A belt drives the driven wheel and the drive wheel. A groove is formed on the inner wall of the connecting rod. A locking block is fixedly connected to the outside of the connecting shaft and rotatably connected to the inside of the groove. Two placement slots are formed on the inner wall of the housing. Elastic components that provide cleaning capabilities are installed inside the placement slots.

[0007] The above technical solution features a double-headed cylinder on the rear of the outer casing. Its output end drives the chuck to move via a connecting rod, facilitating the installation and removal of the take-up and take-down shafts. A mounting plate supports the motor, which drives the connecting shaft to rotate via a drive wheel, driven wheel, and belt, thus transmitting the cold-rolled strip steel. The cooperation between the slot and the locking block ensures more stable rotation of the connecting shaft. The elastic component adapts to the strip steel thickness, improving cleaning efficiency.

[0008] As a further description of the above technical solution:

[0009] The elastic component includes two clamping plates, a second connecting shaft, a spring, and two scrapers. The two clamping plates are slidably connected to the inside of the placement groove. The second connecting shaft is slidably connected to the inner wall of the two clamping plates. The spring is sleeved on the outside of the second connecting shaft. One end of the spring is fixedly connected to the outside of one of the clamping plates, and the other end of the spring is fixedly connected to the outside of the other clamping plate. The outside of both scrapers is fixedly connected to the outside of the clamping plates.

[0010] In the above technical solution, the clamping plate slides within the placement groove in the elastic component, and the connecting shaft provides a sliding guide for the clamping plate. The elasticity of the spring ensures that the scraper remains in contact with the strip surface, effectively removing oil stains. The scraper is made of wear-resistant material, extending its service life. This component has a simple structure, is easy to maintain, and significantly improves degreasing efficiency.

[0011] As a further description of the above technical solution:

[0012] The take-up shaft is externally movably connected to a cold-rolled strip steel, and the two connecting shafts are externally rotatably connected to a protective shell.

[0013] In the above technical solution, the take-up shaft is used to wind the processed strip steel, and the release shaft is used to place the strip steel to be processed. The cold-rolled strip steel is transported between the two shafts, and a protective shell prevents foreign objects from entering the transmission system, ensuring safe operation of the equipment. The movable connection between the chuck and the take-up / release shafts facilitates quick changes to strip steel coils of different specifications, improving production flexibility.

[0014] As a further description of the above technical solution:

[0015] A second protective shell is fixedly connected to the rear side of the outer shell, and a fan is installed inside the second protective shell.

[0016] The above technical solution includes a protective casing that safeguards the fan. The airflow generated by the fan accelerates the drying of the strip surface, reducing water residue. Properly setting the fan direction and speed ensures uniform drying of the strip, improving product quality. The fan features a low-noise design, improving the working environment.

[0017] As a further description of the above technical solution:

[0018] The bottom of the outer casing is provided with multiple drainage holes, and a closed door is movably connected to the outside of the outer casing. Two hinges are fixedly connected to the outside of the closed door and the outside of the outer casing.

[0019] The above technical solution allows for timely drainage of cleaning wastewater through the drain hole, and the closed door is opened and closed via hinges, facilitating equipment maintenance and strip replacement. The hinges are made of high-strength material, ensuring smooth opening and closing of the closed door and good sealing performance. The location of the drain hole is designed to facilitate rapid wastewater drainage, preventing water accumulation that could affect the degreasing effect.

[0020] As a further description of the above technical solution:

[0021] Water pipes are fixedly connected to the inner wall of the closed door and the inner wall of the outer shell. Multiple water nozzles are provided on the inner wall of the outer shell, and a connecting ring is rotatably connected to the outside of the water pipe.

[0022] The above technical solution utilizes a water delivery pipe and a connecting ring to ensure the cleaning fluid is evenly sprayed onto the steel strip surface. The water delivery pipe is made of corrosion-resistant material, extending its service life. The rotating design of the connecting ring allows for adjustment of the spray angle, improving cleaning coverage. This structure is simple and practical, effectively enhancing the cleaning result.

[0023] As a further description of the above technical solution:

[0024] A liquid storage tank is fixedly connected to the top of the outer shell, and a nozzle is fixedly connected to the output end of the liquid storage tank.

[0025] The above technical solution involves storing the cleaning fluid in a storage tank and spraying the atomized cleaning fluid onto the strip steel using a nozzle, thereby improving degreasing efficiency. The nozzle employs a wide-angle design to ensure that the cleaning fluid covers the entire width of the strip steel. The storage tank is equipped with a liquid level observation window for easy and timely replenishment of the cleaning fluid.

[0026] As a further description of the above technical solution:

[0027] The bottom of the outer casing is fixedly connected to two sets of feet, and the outer front side of the closed door is fixedly connected to a handle.

[0028] The above technical solution features a base that supports the equipment, ensuring stable operation. Handles facilitate opening and closing of the sealing door. The height of the feet is adjustable to adapt to different ground conditions. The handle surface is treated with a non-slip coating to improve operating comfort. This design makes equipment installation and use more convenient.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this invention, the control valve inside the storage tank is activated, spraying the cleaning liquid onto both sides of the cold-rolled strip through two nozzles. While the unwinding and rewinding shafts rotate to transport the cold-rolled strip, both sides of the strip are positioned in the middle of two scrapers. The friction between the strip's surfaces and the cleaning surfaces of the scrapers ensures thorough mixing of the grease and cleaning liquid. This structure achieves simultaneous degreasing of both sides of the cold-rolled strip, solving the problem of some devices only degreasing one side, requiring repeated degreasing of the remaining side, resulting in longer working times and lower efficiency.

[0031] 2. In this invention, two scrapers move in opposite directions, causing the clamping plate to slide inside the placement groove. Under the elastic force provided by the spring, the two sides of the cold-rolled strip are slightly clamped. This structure enables the device to degrease cold-rolled strips of different thicknesses, solving the problem of mismatch between the degreasing structure and the different thicknesses of cold-rolled strips in some devices.

[0044] Reference Figures 1 to 9 This utility model provides an embodiment of a degreasing and oil removal device for cold-rolled strip steel, comprising a housing 1 that supports and protects internal components. Two double-headed cylinders 2 are fixedly connected to the rear exterior of the housing 1, driving a connecting rod 3 to move. Connecting rods 3 are fixedly connected to both output ends of the double-headed cylinders 2. A placement plate 20 is fixedly connected to the exterior of the housing 1, and a motor 4 is fixedly connected to the top of the placement plate 20, providing power to drive the take-up shaft 6. A connecting shaft 8 is rotatably connected to the inner wall of the connecting rod 3, supporting a chuck 5 and transmitting power. A chuck 5 is fixedly connected to the exterior of the connecting shaft 8, fixing the take-up shaft 6 and the release shaft 19. The take-up shaft 6 is movably connected inside two of the chucks 5, winding the treated cold-rolled strip steel 16. The release shaft 19 is movably connected inside the other two chucks 5. A drive wheel 7 is fixedly connected to the exterior of one of the connecting shafts 8, transmitting power from the motor 4. A driven wheel 9 is fixedly connected to the exterior of the other connecting shaft 8, cooperating with the drive wheel 7 for transmission. A belt 10 is connected to the external drive wheel 7 and the external drive wheel 9 via a drive belt 10. A groove 17 is provided on the inner wall of the connecting rod 3 to limit the rotation range of the locking block 18. A locking block 18 is fixedly connected to the external side of the connecting shaft 8 to prevent it from falling off. The locking block 18 is rotatably connected to the inside of the groove 17. Two placement slots 11 are provided on the inner wall of the outer casing 1 to accommodate elastic components. Elastic components providing cleaning capabilities are installed inside the placement slots 11.

[0045] The elastic assembly includes two clamping plates 12, a supporting scraper 15, and a connecting spring 14. A connecting shaft 13 slides along the supporting clamping plates 12. The spring 14 provides elasticity to adapt to different thicknesses. The two scrapers 15 remove grease from the surface of the cold-rolled strip steel 16. The two clamping plates 12 are externally slidably connected to the inside of the placement groove 11, and the connecting shaft 13 is externally slidably connected to the inner wall of the two clamping plates 12. The spring 14 is sleeved on the outside of the connecting shaft 13, with one end of the spring 14 fixedly connected to the outside of one of the clamping plates 12 and the other end fixedly connected to the outside of the other clamping plate 12. The two scrapers 15 are both externally fixedly connected to the outside of the clamping plates 12. The cold-rolled strip steel 16, the steel strip to be processed, is movably connected to the outside of the take-up shaft 6. A protective shell 21 is rotatably connected to the outside of the two connecting shafts 1, and a protective shell 22 is fixedly connected to the rear side of the outer shell 1. A fan is installed inside the protective shell 22.

[0046] The bottom of the outer casing 1 has multiple drainage holes. A closed door 28 is movably connected to the outside of the outer casing 1. Two hinges 27 are fixedly connected to the outside of the closed door 28 and the outside of the outer casing 1. Water pipes 23 are fixedly connected to the inner walls of the closed door 28 and the inner walls of the outer casing 1 to transport cleaning water. Multiple spray heads are provided on the inner wall of the water pipes 23. A connecting ring 24 is rotatably connected to the outside of the water pipes 23 to connect to an external water pipe. A liquid storage tank 25 is fixedly connected to the top of the outer casing 1 to store cleaning liquid. A spray head 26 is fixedly connected to the output end of the liquid storage tank 25 to spray the cleaning liquid. Two sets of feet are fixedly connected to the bottom of the outer casing 1, and a handle is fixedly connected to the front of the closed door 28.

[0047] Working principle: The operator opens the closed door 28 by the handle, places the cold-rolled strip 16 that needs to be degreased outside the unloading shaft 19, connects the other end of the cold-rolled strip 16 to the take-up shaft 6, and starts the two cylinders 2. The two output ends of the cylinders 2 drive the connecting rod 3 to retract. When the connecting rod 3 approaches the middle of the outer shell 1, it drives the two connecting shafts 8 and the two chucks 5 to move synchronously to the middle of the outer shell 1, so that the unloading shaft 19 and the take-up shaft 6 are clamped.

[0048] The motor 4 is started, and its output drives one of the connecting shafts 8 and the take-up shaft 6 to rotate. The rotation of the connecting shaft 8 also drives the drive wheel 7 to rotate. The drive wheel 7, under the power transmission of the belt 10, drives the driven wheel 9 to rotate. The driven wheel 9 drives the other connecting shaft 8 and the unloading shaft 19 to rotate. Meanwhile, the locking block 18 rotates inside the locking groove 17 to prevent the connecting shaft 8 from falling out of the connecting rod 3 when the cylinder 2 extends, thus allowing the cold-rolled strip steel 16 to be transported. While the cold-rolled strip steel 16 is being transported downwards, the control valve inside the liquid storage tank 25 is activated, spraying the cleaning liquid onto both sides of the cold-rolled strip steel 16 through the two spray nozzles of the nozzle 26. While the unloading shaft 19 and the take-up shaft 6 are rotating to transport the cold-rolled strip steel 16, both sides of the cold-rolled strip steel 16 are placed in the middle of the two scrapers 15. The two sides of the cold-rolled strip steel 16 rub against the cleaning surfaces of the two scrapers 15, so that the grease on the cold-rolled strip steel 16 is fully mixed with the cleaning liquid.

[0049] After the grease and cleaning solution on the cold-rolled strip are mixed, when it is transferred to the lower part of the device, the external water pipe is connected to the connecting ring 24 to transmit water. The water is then sprayed onto both sides of the mixed cold-rolled strip 16 through several spray nozzles outside the water pipe 23, rinsing away the cleaning solution and grease. At the same time, the fan inside the protective shell 22 is started. After the cold-rolled strip is completely cleaned, hot air transmitted by the fan is used for drying. The sprayed oil mixture is discharged through the drain hole at the bottom of the shell 1. When it is necessary to remove grease from cold-rolled strip 16 of different thicknesses, when the cold-rolled strip is thicker, the two scrapers 15 are moved in opposite directions, causing the clamping plate 12 to slide inside the placement groove 11. Under the elastic force provided by the spring 14, the two sides of the cold-rolled strip 16 are slightly clamped to accommodate cold-rolled strip 16 of different thicknesses.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
