Description

Technical Field

[0001] This invention relates to the field of cold-rolled strip processing technology, specifically to a leveling device for cold-rolled strip processing. Background Technology

[0002] Cold-rolled strip steel refers to steel strip and sheet produced by cold rolling at room temperature using hot-rolled strip steel and steel plate as raw materials. This type of steel has advantages such as good surface finish, good flatness, high dimensional accuracy and good mechanical properties. The products are usually in coils, and a large part of them are processed into coated steel sheets. When processing cold-rolled strip steel, a flattening device is generally required to flatten the cold-rolled strip steel.

[0003] In existing cold-rolled strip steel leveling operations, leveling fluid is required. The traditional method of application is spraying, which makes it difficult for the leveling fluid to be absorbed evenly, resulting in significant waste. To address this, patent application CN202423084105.8 discloses a leveling device for cold-rolled strip steel processing, relating to the field of cold-rolled strip steel processing equipment. The device includes a main body with a lower pressure roller located below its interior. A fluid feeding mechanism is located on one side of the lower pressure roller. The fluid feeding mechanism includes an electric... The machine, through the setting of a liquid loading mechanism, allows the cold-rolled strip steel to enter the upper and lower suction rollers after being heated by the heating mechanism. At this time, the liquid pump inside the liquid tank can be started by an external controller to introduce the leveling liquid into the liquid storage tank. Then, the motor is started, which drives the first gear and the second gear to rotate. Subsequently, the first gear and the second gear drive the upper and lower suction rollers to rotate. During the rolling of the lower suction roller, the leveling liquid can be effectively wrapped onto the lower suction roller, which facilitates the liquid loading of the cold-rolled strip steel onto the ground.

[0004] While the existing leveling device described above is highly efficient in coating cold-rolled strip steel by wrapping the leveling liquid around the outside of the lower suction roller, it will affect the uniformity and quality of the coating when the leveling liquid wrapped around the outside of the lower suction roller is uneven.

[0015] Preferably, the scraper has a vertical groove inside, and the scraper is vertically limited and slidably connected to the side of the stirring rod through the vertical groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention, by setting up a coating and smoothing device, utilizes the rotational power of the second gear to precisely drive the spray coating assembly to reciprocate along a flat frame at a specific inclination angle via a pulley set, crank rod, and intermittent assembly. This allows the slit nozzle to dynamically and uniformly spray the steel strip surface following the moving trajectory, effectively avoiding localized over- or under-spraying caused by fixed spraying.

[0018] This invention employs a spray coating assembly, where the coating roller is elastically connected to a movable first plate via a connecting rod and a second spring. As it reciprocates along an inclined track, it not only performs rolling smoothing but also adaptively maintains a constant pressure on the strip surface under the action of the second spring. This reciprocating motion, in conjunction with the inclined track, creates a periodically varying, three-dimensional extrusion effect perpendicular to the strip surface during the smoothing process. This strongly promotes the penetration and extension of the leveling liquid into the microstructure of the strip surface, significantly improving the uniformity and density of the liquid film adhesion. This solves the problem of unstable coating quality caused by uneven pressure or insufficient contact in traditional single-roller coating.

[0019] This invention cleverly converts the rotational motion of the crankshaft into intermittent 90-degree rotation of the rotor, driving the stirring rod and blades to thoroughly stir the liquid. This effectively prevents solid particles from settling and the liquid from separating. Combined with the continuous scraping of the tank wall by the following scraper, it avoids the adhesion of the leveling liquid. This ensures that the leveling liquid supplied to the spray head remains uniform in composition and stable in properties during long-term continuous operation, guaranteeing the uniformity and consistency of the spraying quality.

[0020] This invention establishes a closed-loop system for leveling liquid coating, recycling, and reuse by setting up a collection and coating assembly. The collection box and its internal collection tank can effectively receive and store excess leveling liquid dripping from the edge of the strip or overflowing during the process. The auxiliary roller rotating inside the collection tank will adhere to the excess leveling liquid and, as the strip is conveyed, replenish the coating on its lower surface. In this way, not only is the waste liquid recycled, significantly reducing the unit consumption and production cost of leveling liquid, but the lower surface of the strip is also moistened twice, synergistically improving the overall coating uniformity of the upper and lower surfaces of the strip, demonstrating the dual benefits of energy saving, environmental protection, and quality improvement.

Detailed Implementation

[0035] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0036] Please see Figures 1-2 This invention provides a leveling device for cold-rolled strip steel processing, including a housing 1, with leveling frames 2 fixedly connected to the front and rear sides of the housing 1, a protective frame 3 locked to the top of the housing 1, a motor 4 installed at the lower end of the housing 1, a transmission belt assembly 5 connected to the output end of the motor 4, the upper end of the transmission belt assembly 5 being rotatably connected to a first gear 6, the top of the first gear 6 being meshed with a second gear 7, a first pressure roller 8 and a second pressure roller 9 respectively connected to the left side of the first gear 6 and the second gear 7, and the first pressure roller 8 and the second pressure roller 9 being installed at the lower and upper ends of the protective frame 3 respectively, and also including a coating and smoothing device 10 installed outside the front leveling frame 2 and a coating collection assembly 11 connected to the front end of the front leveling frame 2.

[0038] Please see Figures 3-4In this embodiment, the coating and smoothing device 10 includes a housing 101, which is fitted onto the outside of the front leveling frame 2 and locked to the upper end of the box 1 by bolts. A detachable observation window 102 is installed on the front side of the housing 101 to facilitate the operator's observation of the internal working status.

[0039] Please see Figures 5-7 In this embodiment, the intermittent component 105 includes a first bevel gear 1051, which is connected to the left side of the crankshaft 104. The first bevel gear 1051 is externally fixed to the right side of the housing 101 via a first bracket 1052. A second bevel gear 1053 is rotatably mounted on the upper end of the first bracket 1052, meshing with the first bevel gear 1051. A triangular block-shaped top block 1054 is fixed to the upper end of the second bevel gear 1053. A switching plate 1055 is positioned opposite the top of the top block 1054. A drive shaft 1056 is located on each side of the bottom of the switching plate 1055. The left side of the switching plate 1055 is inserted into the second bracket 1057. The inner part is connected to the outer swing arm 1058. The bottom of the swing arm 1058 is provided with a limiting frame 1059. A slider 10510 is slidably installed in the frame. The slider 10510 slides up and down along the outside of the vertical rod 10511. The upper end of the vertical rod 10511 is fitted with a first spring 10512. The lower end of the first spring 10512 abuts against the slider 10510. The slider 10510 is rotatably connected to the second bracket 1057 through the first connecting arm 10513. The bottom of the swing arm 1058 is connected to the front side of the connecting rod 10515 through the second connecting arm 10514. The left and right ends of the connecting rod 10515 are bolted to the spray coating assembly 106.

[0040] Please see Figures 8-9In this embodiment, the spray coating assembly 106 includes a first receiving plate 1061. The first receiving plate 1061 is symmetrically arranged at the left and right ends of the connecting rod 10515. The bottom of the first receiving plate 1061 is provided with two sets of plug rods 1062 and a second spring 1063, and is elastically connected to the second receiving plate 1064 through the two sets of plug rods 1062 and the second spring 1063. Coating rollers 1065 are rotatably mounted on the bottom of the second receiving plates 1064 on both sides, and the bottom of the coating rollers 1065 is connected to the front... The side leveling frame 2 is internally abutted, and the first connecting plate 1061 on both sides is fixed with a side plate 1066. The side plates 1066 on both sides are slidably connected to the inside of the housing 101 for front and rear guidance. A conveying pipe 1067 is connected between the bottom of the side plates 1066 on both sides. The upper end of the conveying pipe 1067 is connected to the pump body of the liquid storage tank 108 via a corrugated pipe 1068. The bottom of the pipe has slit nozzles 1069 evenly distributed in the transverse direction for uniformly spraying the leveling liquid onto the surface of the cold-rolled strip steel.

[0041] Please see Figures 10-11In this embodiment, the hybrid component 107 includes a first connecting rod 1071. The first connecting rod 1071 is locked to the outside of the crankshaft 104 by a bottom clamp structure, and lubricating oil is applied between the clamp structure and the crankshaft 104 to ensure smooth reciprocating push-pull process of the crankshaft 104 on the first connecting rod 1071. At the same time, the first connecting rod 1071 extends upward out of the housing 101 and is limited and inserted into the bracket provided on the right side of the housing 101. A second connecting rod 1072 is horizontally fixed at the upper end of the first connecting rod 1071. A third connecting rod 1073 is vertically locked to the left side of the second connecting rod 1072. The third connecting rod 1073 extends downward into the liquid storage tank 108, and its end is connected to the fixing frame 1074. A third spring 1075 is provided inside the fixing frame 1074. The bottom of the third spring 1075 is connected to the limiting plate 1076. The limiting plate 1076 can slide vertically and vertically along the inside of the fixing frame 1074. A rotating rod 1077 is rotatably installed at the bottom of the limiting plate 1076. A convex shaft 1078 is provided on the front side of the upper end of the rotating rod 1077. A first trigger plate 1079 and a second trigger plate 10710 are respectively installed on both sides, and the upper end of the second trigger plate 10710 is locked to the fixing frame 1074. Both the first trigger plate 1079 and the second trigger plate 10710 have a wave groove in the middle, and the convex shaft 1078 is embedded in the groove. That is, as the first trigger plate 1079 and the second trigger plate 10710 move up and down, the convex shaft 1078 will be driven accordingly, so that it cooperates with the upper and lower wave grooves to realize the intermittent 90° rotation transmission of the rotating rod 1077. The first trigger plate 1079 and the second trigger plate 10710 are both limited and slidable by limiting rods 10711 on both sides. The top of the limiting rods 10711 on both sides is fixed to the upper end of the liquid storage tank 108. The bottom of the rotating rod 1077 is equipped with a stirring rod 10712 and a blade 10713 from top to bottom. The stirring rod 10712 is vertically slidably inserted into the groove inside the scraper 10714 on both sides. The scraper 10714 can rotate and scrape along the inside of the liquid storage tank 108 to achieve the dual functions of stirring and scraping the wall.

[0042] Please see Figures 12-13 In this embodiment, the coating collection assembly 11 includes a collection box 111, a collection trough 112 and an auxiliary roller 113. The collection box 111 is locked to the front end of the front flattening frame 2. The collection box 111 has a collection trough 112 inside, and the auxiliary roller 113 is rotatably installed inside the collection trough 112.

[0043] The working principle is as follows:

[0044] First, start motor 4, whose output shaft drives the first gear 6 to rotate through the transmission belt group 5. The first gear 6 meshes with the second gear 7 above, thereby synchronously driving the first pressure roller 8 and the second pressure roller 9 connected to the left of the two to rotate in opposite directions. The cold-rolled strip passes between the two pressure rollers, and under the pressure and rotation of the two pressure rollers, continuous and stable flattening processing is achieved.

[0045] When the motor 4 drives the second gear 7 to rotate, its rotational power is transmitted to the crank 104 through the pulley set 103. The rotation of the crank 104 drives the triangular block 1054 at the upper end of the second bevel gear 1053 to rotate through the meshing of the first bevel gear 1051 and the second bevel gear 1053. The block 1054 periodically pushes the two transmission shafts 1056 on both sides of the bottom of the switching plate 1055, causing the switching plate 1055 to swing around the second bracket 1057. Then, through the linkage mechanism composed of the swing arm 1058, the first connecting arm 10513, the second connecting arm 10514 and the connecting rod 10515, the spray coating assembly 106 is finally driven to slide back and forth along the inclined direction of the front flat frame 2. This intermittent transmission mechanism accurately converts the rotational motion of the motor 4 into the linear reciprocating motion of the spray coating assembly 106.

[0046] While the spray coating assembly 106 reciprocates back and forth, the pump body connected to the liquid storage tank 108 pumps the leveling liquid through the corrugated pipe 1068 into the delivery pipe 1067, and the evenly distributed slit nozzles 1069 at its bottom spray evenly onto the surface of the cold-rolled strip steel passing below along the moving trajectory. Immediately afterwards, the coating roller 1065 installed at the bottom of the second receiving plate 1064 smooths the liquid film. The key point is that the coating roller 1065 is elastically connected to the first receiving plate 1061, which moves back and forth, through the plug rod 1062 and the second spring 1063. As the entire assembly slides back and forth along the inclined leveling frame 2, the coating roller 1065, under the action of the second spring 1063, always adheres to the strip surface with adaptive pressure. This combination of moving spraying and elastic pressing makes the coating roller 1065 not only generate rolling friction during the leveling process, but also generate a periodic, three-dimensional extrusion effect perpendicular to the strip surface due to the coordination of the movement direction and the inclined surface. This significantly enhances the penetration and uniformity of the leveling liquid, overcoming the problem of uneven liquid film that may be caused by traditional fixed rollers or simple horizontal leveling.

[0047] Meanwhile, during the rotation of the crankshaft 104, the first connecting rod 1071, connected by a clamp, drives the mixing assembly 107 to reciprocate up and down. This reciprocating motion is transmitted to the fixing frame 1074 inside the liquid storage tank 108 through the second connecting rod 1072 and the third connecting rod 1073, and then acts on the limiting plate 1076 and the rotating rod 1077 via the third spring 1075. The convex shaft 1078 at the upper end of the rotating rod 1077 is located in the wavy groove of the fixed second trigger plate 10710 and the moving first trigger plate 1079. The motion converts the vertical linear motion into periodic 90-degree intermittent rotation of the rotating rod 1077. The stirring rod 10712 and blade 10713 at the bottom of the rotating rod 1077 rotate accordingly, which fully stirs the leveling liquid in the storage tank 108 to prevent solid components from settling. At the same time, the scraper 10714, which is slidably connected to the stirring rod 10712, scrapes against the inner wall of the storage tank 108 as it rotates, effectively preventing the leveling liquid from adhering. This ensures that the leveling liquid supplied to the spray head 1069 always has a uniform concentration and stable properties, thus guaranteeing the uniformity of the coating quality.

[0048] The coated cold-rolled strip is guided forward by the auxiliary roller 113. Any excess leveling liquid that drips or overflows during the process is effectively collected by the collection tank 112 below and flows into the collection box 111, realizing the recycling and reuse of resources and embodying the concept of energy conservation and environmental protection. The excess leveling liquid collected inside the collection tank 112 adheres to the outside of the auxiliary roller 113 to coat the lower surface of the conveyed cold-rolled strip with leveling liquid, thereby improving the uniformity of leveling liquid coating on the upper and lower surfaces of the cold-rolled strip.

[0049] In summary, the reciprocating spraying combined with the coating roller 1065 on the inclined track enables the leveling liquid coating to change from planar coverage to three-dimensional penetration and compaction, greatly improving uniformity and adhesion. This solves the problems of quality defects and liquid waste caused by uneven coating. The mixing component 107 built into the storage tank ensures the stability of the leveling liquid properties during operation, and the setting of the coating collection component 11 enables the recovery of residual liquid, reducing production costs.
