Description

Technical Field

[0001] The utility model belongs to the technical field of steel strip production, in particular to a steel strip surface cleaning device. Background Art

[0002] The production process of steel strip before it is made into coils includes multiple steps, including hot rolling, cold rolling, pickling, galvanizing, and coating. During each step, the steel strip surface may become contaminated to varying degrees. For example, during cold rolling and other processes requiring lubrication, if the large amount of lubricating oil used is not effectively removed, it will remain on the steel strip surface and form oil spots. Emulsions, composed of oil, water, and emulsifiers, can also easily form uneven residue on the steel strip surface if the ratio or stability is poor.

[0003] Current methods for reducing oil spots or emulsion residues include using visual equipment to detect surface defects on the steel strip and then cleaning the surface, but the equipment usage cost is high; reducing emulsion residues by optimizing the components of the emulsion, adjusting the emulsion parameters, and controlling the emulsion usage indicators, but this method has high production requirements and is not universally applicable under complex working conditions; in addition, oil spots and emulsions can be blown away from the surface of the steel strip by blowing equipment, but the removal effect is also poor. Utility Model Content

[0004] The purpose of the utility model is to provide a steel strip surface cleaning device to solve the problems raised in the above-mentioned prior art.

[0005] A steel strip surface cleaning device is provided, comprising:

[0006] conveyor;

[0007] Two upright posts, the two upright posts being respectively located on both sides of the conveyor belt;

[0008] A clamping beam, wherein the clamping beam is fixedly connected to the two columns;

[0009] Two pressing plates, the two pressing plates are vertically arranged inside the clamping beam, and cleaning surfaces are respectively provided on opposite surfaces of the two pressing plates;

[0010] A compression adjustment device is used to adjust the compression force between the compression plate and the steel belt.

[0011] The steel strip is transported by rollers on the conveyor belt and is coiled into a steel coil at the end of its travel. The two columns are the primary support structure for the cleaning device, supporting the clamping beam and two pressure plates. The pressure adjustment device adjusts the pressure between the pressure plates and the steel strip. While the steel strip can pass smoothly between the two pressure plates, a certain pressure is applied to improve the contact between the cleaning surface and the steel strip, ensuring effective cleaning. In addition to carrying the pressure adjustment device and securing the pressure plates, the clamping beam also serves to block the pressure plates, preventing them from being dragged by the steel strip due to friction and causing them to move.

[0012] Furthermore, the top plate of the clamping beam spans the conveyor belt and is fixedly connected to two columns at both ends, forming an open structure between the side of the clamping beam away from the conveyor belt's transport direction and the columns. The clamping beam provides protection to the compression plate in all directions as much as possible to prevent external dust or debris from coming into contact with the compression plate and affecting its use. The clamping beam remains open on one side to facilitate the installation of the compression plate and to provide installation space for the compression plate. The direction of the opening structure is opposite to the conveying direction of the conveyor belt so that the side plate of the clamping beam away from the opening structure can limit the compression plate and prevent displacement of the compression plate.

[0013] Furthermore, the clamping adjustment device includes a plurality of adjusting bolts arranged along the length of the clamping beam. The adjusting bolts are threaded through the clamping beam and engage a clamping plate located above. Rotating the adjusting bolts adjusts the distance and contact force between the adjusting bolts and the clamping plate. When the adjusting bolts disengage from the clamping plate, the clamping plate can be smoothly removed from the clamping beam. When the adjusting bolts engage the clamping plates, the steel strip is tightly clamped between the two clamping plates.

[0014] Furthermore, two adjusting bolts are provided, one on each supporting beam located at the top of each column. When the conveyor belt is wide, it is inconvenient for operators to adjust the adjusting bolts in the middle of the conveyor belt. Therefore, adjusting bolts are not provided in the middle of the clamping beam, but only at the ends of the clamping beam to facilitate operation. The adjusting bolts adjust the clamping force between the clamping plate and the steel belt, which is then transmitted to the columns for support.

[0015] Furthermore, the compression adjustment device is a drive assembly, which is disposed within the column. The drive assembly avoids the lower compression plate and cooperates with the upper compression plate to drive the upper compression plate up and down. The drive assembly drives the upper compression plate up and down, eliminating the need for manual operation. Furthermore, the drive assembly is automatically controlled by a mechanical structure, providing more precise adjustment capabilities than manual adjustment.

[0016] Furthermore, the drive assembly is a screw assembly. The screw assemblies in the two columns bypass the lower pressure plate and are threaded through the upper pressure plate. The screw assemblies at both ends drive the pressure plate up and down through synchronous rotation, which can achieve high adjustment accuracy and make the pressure between the steel belt and the pressure plate controllable.

[0017] Furthermore, the drive assembly is an actuator, and the actuators in the two columns are fixedly connected to the upper pressure plate after bypassing the lower pressure plate. The actuator is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder, and has a large load capacity and a wide range of adjustment of the pressure between the steel belt and the pressure plate.

[0018] Furthermore, a soft pad is provided between the pressing plate and the cleaning surface to provide soft contact between the steel strip and the cleaning surface, thereby preventing the pressing plate from scratching the steel strip surface due to excessive pressing force and preventing the cleaning surface from being worn out too quickly.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] When the steel belt is on the surface of the conveyor belt for transportation, the steel belt needs to pass between the two compression plates. After the compression force between the compression plates and the steel belt is adjusted by the compression adjustment device, the two surfaces of the steel belt can be cleaned through the cleaning surface to remove the oil stains or emulsion on the surface of the steel belt, thereby achieving the cleaning of the steel belt.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 and Figure 3 As shown, in an embodiment of the utility model, a steel belt surface cleaning device includes a conveyor belt 1, two columns 2, a clamping beam 3, two pressure plates 4 and a pressure adjustment device 5. The two columns 2 are respectively located on both sides of the conveyor belt 1, the clamping beam 3 is fixedly connected to the two columns 2, the two pressure plates 4 are vertically arranged inside the clamping beam 3, and cleaning surfaces 41 are respectively provided on the opposite surfaces of the two pressure plates 4. The pressure adjustment device 5 is used to adjust the pressure between the pressure plate 4 and the steel belt.

[0029] The top plate of the clamping beam 3 spans the conveyor belt 1 and is fixedly connected to the two columns 2 at both ends, so that the clamping beam 3 can cover most of the range of the clamping plate 4 and protect the clamping plate 4. The clamping beam 3 and the columns 2 are connected to each other through side panels to form a whole. A certain distance is reserved between the side panel of the clamping beam 3 close to the conveying direction and the conveyor belt 1 to provide running space for the steel belt. An opening structure is formed between the side of the clamping beam 3 away from the transport direction of the conveyor belt 1 and the column 2. The opening structure is to facilitate the entry and exit of the clamping plate 4 between the clamping beam 3, the column 2 and the conveyor belt 1, and to provide running space for the steel belt. At the same time, it is convenient for the staff to clean the contact between the surface 41 and the steel belt.

[0030] Cleaning surface 41 can be made of a material such as felt, linen, or fiber felt that absorbs oil stains and emulsions. It covers the outer surface of pressure plate 4 and contacts the steel strip. Two pressure plates 4 are provided, clamping the steel strip between them. Applying a certain amount of pressure, they simultaneously remove oil stains and emulsions from both sides of the steel strip.

[0031] Further, see Figure 3As shown, a soft pad 42 is provided between the pressing plate 4 and the cleaning surface 41. The soft pad 42 provides soft contact between the steel strip and the cleaning surface 41, while providing compressive force through elastic deformation, thereby preventing the pressing plate 4 from scratching the steel strip surface due to excessive pressing force and preventing the cleaning surface 41 from being worn out too quickly, thereby protecting the steel strip and the cleaning surface 41.

[0032] In one embodiment, the clamping adjustment device 5 includes a plurality of adjusting bolts 51, which are arranged along the length direction of the clamping beam 3. The adjusting bolts 51 are threaded through the clamping beam 3 and can contact the clamping plate 4 located at the top. This solution is to adjust the clamping force of the clamping plate 4 by manual adjustment. Specifically, before the steel belt is conveyed, the adjusting bolts 51 are loosened so that the upper clamping plate 4 has a certain lifting space. After the upper clamping plate 4 is manually lifted and the front end of the steel belt passes between the two clamping plates 4, the upper clamping plate 4 is released and the adjusting bolts 51 are re-tightened to make the steel belt in close contact with the two clamping plates 4. Then, the conveyor belt 1 is started. During the movement of the steel belt, the oil spots and emulsion on the surface of the steel belt are adsorbed onto the cleaning surface 41.

[0033] Further, see Figure 2 As shown, two adjusting bolts 51 are provided, one on each of the clamping beams 3 located at the top of the two columns 2. This solution is suitable for conveyor belts 1 with large widths. When the conveyor belt 1 is wide, it is inconvenient for operators to adjust the adjusting bolts 51 in the middle of the conveyor belt 1. Therefore, adjusting bolts 51 are not provided in the middle of the clamping beam 3, but only at the ends of the clamping beam 3 to facilitate operation. The adjusting bolts 51 adjust the clamping force between the clamping plate 4 and the steel belt, which is further transmitted to the columns 2, providing support through the columns 2.

[0034] It should be noted here that in order to prevent the upper clamping plate 4 from increasing in length synchronously with the increase in the width of the conveyor belt 1, and causing the middle part of the clamping plate 4 to arch and warp after the two ends of the clamping plate 4 are subjected to force due to the increase in length, resulting in insufficient contact force between the middle part of the upper clamping plate 4 and the steel belt, the clamping upper clamping plate 4 should be made of a material with greater rigidity and less prone to deformation.

[0035] In one embodiment, the clamping adjustment device 5 is a drive assembly that can drive a spindle through a drive device. The drive assembly is located within the column 2. After extending from the column 2, the spindle of the drive assembly clears the lower clamping plate 4 and engages with the upper clamping plate 4. The spindle's movement drives the upper clamping plate 4 up and down to adjust the clamping force between the clamping plate 4 and the steel strip, or to adjust the distance between the two clamping plates 4. This solution eliminates the inconvenience of manual operation and utilizes mechanical equipment to automatically or semi-automatically control the clamping plate 4, reducing labor costs.

[0036] Specifically, the drive assembly is a screw assembly, which includes a motor and a screw. The motor drives the screw to rotate. The screws in the two columns 2 extend from the columns 2, bypass the lower clamping plate 4, and then respectively thread through the upper clamping plate 4. When the motor drives the screws to rotate forward and reverse, the clamping plate 4 can be raised and lowered on the screws under the action of the threads, and the lifting precision is high.

[0037] Specifically, the drive assembly is an actuator, which can be a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The main shafts of the actuators in the two columns 2 extend out of the columns 2, clear the lower clamping plate 4, and are fixedly connected to the upper clamping plate 4. The actuators drive the clamping plate 4 via the main shafts to achieve the lifting and lowering motion.

[0038] The steel strip is conveyed by the conveyor belt 1. The drive assembly drives the upper pressure plate 4 to lift, allowing the steel strip to pass smoothly between the two pressure plates 4. After the steel strip passes through, the drive assembly drives the upper pressure plate 4 to press down until it contacts the steel strip and maintains a certain pressure. During the continuous conveyance of the steel strip, the cleaning surface 41 removes oil stains and emulsions on the surface of the steel strip by adsorption.

[0039] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the scope of protection of the present utility model.
