Description

Technical Field

[0001] The invention belongs to the technical field of cleaning equipment, in particular to a substrate cleaning device for color-coated plate processing. Background Art

[0002] Color coated steel sheet, also known as color steel sheet or color plate, is a product made of cold rolled steel sheet and galvanized steel sheet as substrate, which is coated with paint (roller coating) in a continuous manner after surface pretreatment (degreasing, cleaning, chemical conversion treatment), and then baked and cooled. The coated steel sheet is light, beautiful, and has good corrosion resistance. It can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc., and has achieved good results such as replacing wood with steel, efficient construction, energy saving, and pollution prevention.

[0003] In the production process of color-coated plates, cleaning is to remove oil stains, iron powder or conversion films (such as passivation films) on the surface of the substrate that have an adverse effect on product quality, so as to provide a clean surface for subsequent processes, thereby laying the foundation for improving the adhesion between the substrate and the paint and the corrosion resistance of the product. Studies have shown that the quality of color-coated plates depends first on cleaning and chemical conversion, so the cleaning process is an important link in ensuring the quality of color-coated plates.

[0004] In the related art, when cleaning the substrate of the color-coated plate, the cleaning liquid is usually used to soak and spray the substrate, and the oil, iron powder, carbon powder, etc. on the substrate are removed by the impact of the water flow. When there are many impurities such as oil, iron filings, and carbon powder distributed on the substrate, in order to ensure the cleaning effect, the substrate is usually cleaned by brushing. For example, a Chinese patent discloses a cleaning device for hot-dip galvanized color-coated plate production, and the application number is 2023109668597. In this scheme, the upper and lower cleaning rollers are combined with a scraper to roll and brush the surface of the substrate, which effectively enhances the cleaning effect of the substrate. However, in actual application, it is found that when the roller and brush are used to roll and rub the surface of the substrate, the iron filings and other impurities cleaned are easy to adhere to the surface of the roller and brush, and even in the gap between the bristles of the roller brush unit. When the roller and the substrate are in rolling contact, the iron filings remaining on the roller will cause scratches and scratches on the surface of the substrate, affecting the quality of the color-coated plate.

[0043] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0044] As Figures 1 to 11 shown, a substrate cleaning device for color-coated board processing according to the present invention includes a cleaning tank 1 and a conveying assembly. The cleaning tank 1 is filled with a cleaning aqueous solution, and the conveying assembly is installed on the cleaning tank 1;

[0045] The conveying assembly includes a traction roller 11 and a guide roller 12. The traction roller 11 is symmetrically installed at one end of the cleaning tank 1. The traction roller 11 is used to traction the substrate. The guide roller 12 is rotatably installed in the cleaning tank 1. Multiple guide rollers 12 cooperate with the traction roller 11 to fix the movement path of the substrate;

[0046] It further includes a cleaning assembly. The cleaning assembly includes a spraying assembly and a brushing assembly. The spraying assembly and the brushing assembly are both installed in the cleaning tank 1. The spraying assembly and the brushing assembly are both divided into two groups. The two groups of spraying assemblies and brushing assemblies are symmetrically designed, and the gaps between the two groups of spraying assemblies and brushing assemblies are both located on the movement path of the substrate;

[0047] The spraying assembly is installed on the cleaning tank 1. The spraying assembly is composed of a plurality of spray pipes 13;

[0048] The brushing assembly includes a roller brush unit. The roller brush unit is rotatably installed in the cleaning tank 1;

[0049] A comb tooth plate 2. The comb tooth plate 2 is installed in the cleaning tank 1. The comb tooth plate 2 corresponds to the roller brush unit one by one, and the comb tooth plate 2 is located on the rotation path of the roller brush unit. The comb tooth plate 2 is used to clean the roller brush unit;

[0050] A rotating motor 21. The rotating motor 21 is connected to the roller brush unit. The rotating motor 21 is used to switch the angle of the roller brush unit;

[0051] In the preparation process of color-coated plates, the cleaning effect of the substrate has a great impact on the quality of the finished color-coated plates. To enhance the cleaning effect of the substrate, brush scrubbing is usually combined with water flow impact to enhance the removal effect of oil stains, iron filings, and carbon powder on the substrate. At the same time, in actual application, to avoid the problem of scrubbing scratches caused by the adhesion of oil stains and iron filings to the brush, in the present invention, a comb tooth plate 2 is provided to clean the brush, and through the cooperation of scrubbing and spraying, while ensuring the cleaning effect of the substrate, the probability of scratching the substrate is reduced;

[0052] Specifically, when cleaning the substrate, one end of the coiled substrate is introduced into the conveying assembly. The traction roller 11 of the conveying assembly forms traction on one end of the substrate, and at the same time, in cooperation with the guide roller 12 located in the cleaning tank 1, the movement path of the substrate in the cleaning tank 1 is fixed. Under the traction of the traction roller 11, the substrate moves from one end of the cleaning tank 1 to the other end along the fixed path. During the movement of the substrate in the cleaning tank 1, it is affected by the cleaning assembly. Specifically, under the action of the guide roller 12, the substrate enters the cleaning tank 1 and moves below the liquid level of the cleaning aqueous solution in the cleaning tank 1. After being soaked in the cleaning aqueous solution, the substrate first contacts the scrubbing assembly. The scrubbing assembly consists of a rotary brush unit, a comb tooth plate 2, and a rotary motor 21. During the movement of the substrate, the rotary assembly drives the rotary brush unit to rotate. The rotation direction of the rotary brush unit is opposite to the movement direction of the substrate, and the rotary brush units are symmetrically distributed on both sides of the substrate. Therefore, during the rotation of the rotary brush unit, the surface bristles scrub the substrate, causing the oil stains, iron filings, carbon powder and other dirt on the substrate surface to be affected by the frictional force. Part of the dirt diffuses into the cleaning aqueous solution, and the other part of the dirt adheres to the bristles on the surface of the rotary brush unit. As the rotary brush unit continues to rotate, the rotary brush unit contacts the comb tooth plate 2, and the comb teeth of the comb tooth plate 2 extend into the bristles on the surface of the rotary brush unit, thereby realizing the cleaning of the bristles, intercepting and removing solid impurities, and further reducing the probability of solid dirt being mixed in the bristles. When the rotary brush unit contacts the substrate again, the probability of the bristles scratching the substrate is reduced. After the substrate separates from the rotary brush unit, as the substrate continues to move, the substrate is impacted by the cleaning aqueous solution sprayed by the spraying assembly, further cleaning the substrate, and finally completing the cleaning operation of the substrate;

[0053] In the present invention, by setting the rotary brush unit and the comb tooth plate 2 to cooperate, during the movement of the substrate, the rotary brush unit performs rolling friction on the substrate, and during the rotation of the rotary brush unit, the comb tooth plate 2 cleans the bristles on the surface of the rotary brush unit, thereby reducing the probability of solid dirt adhering to the rotary brush unit, and further reducing the probability of the substrate surface being scratched during the scrubbing process.

[0054] As a preferred embodiment of the present invention, the rotary brush unit includes a symmetrically designed support frame 22, on which a plurality of roller brushes 23 are rotatably installed together. The roller brushes 23 are evenly arranged along the circumferential direction of the support frame 22, and the output end of the rotary motor 21 is fixedly connected to the support frame 22;

[0055] Mounting plates 24 are symmetrically installed in the cleaning tank 1. The mounting plates 24 correspond to the support frames 22 one by one. Transmission cavities 25 are formed on the sides of the mounting plates 24 close to each other. The support frames 22 are rotatably installed in the transmission cavities 25;

[0056] The comb-shaped plate 2 is fixedly installed between the symmetrically arranged mounting plates 24;

[0057] The rotary brush unit further includes a driving wheel 26 and a driven wheel 27. The driving wheel 26 and the driven wheel 27 are rotatably installed in the transmission cavity 25. The driven wheels 27 are fixedly installed on the roller brushes 23. The driving wheel 26 meshes with the driven wheel 27, and the driving wheel 26 corresponds to the driven wheel 27 one by one. A plurality of the driving wheels 26 are connected by belt drive;

[0058] A driving motor 28 is fixedly installed on the mounting plate 24. The output end of the driving motor 28 extends into the transmission cavity 25, and the output end of the driving motor 28 is fixedly connected to the driving wheel 26;

[0059] The rotary brush unit is designed in plural, and a plurality of rotary brush units are arranged along the movement path of the substrate.

[0060] The driving wheel 26 close to the movement path of the substrate has a large diameter, and the driving wheel 26 far from the movement path of the substrate has a small diameter;

[0061] In practical applications, in order to further enhance the cleaning effect on solid dirt between the bristles, when the substrate moves, the drive motor 28 is started, and the drive motor 28 directly drives the driving wheel 26 to rotate. Since the multiple driving wheels 26 are connected by belt drive, when one of the driving wheels 26 rotates, the remaining driving wheels 26 all rotate. And the driving wheels 26, the transmission wheels 27, and the roller brushes 23 correspond one by one. Therefore, the multiple roller brushes 23 on the support frame 22 rotate, and the rotation direction of the roller brushes 23 is opposite to the movement direction of the substrate, thereby realizing the frictional cleaning of the substrate surface. At the same time, when the drive motor 28 is working, the rotation motor 21 operates synchronously. Therefore, during the entire brushing process, at the same moment, some of the roller brushes 23 on the roller brush unit are in contact with the substrate to clean the substrate surface. As the brushing operation progresses, the impurities adhered to this part of the roller brushes 23 gradually increase. Therefore, when the cleaning time of this part of the roller brushes 23 reaches a preset value, under the control of a preset program, the rotation motor 21 is started, and the rotation motor 21 drives the support frame 22 to rotate, thereby switching the angle of the roller brush unit, so that the roller brushes 23 in contact with the substrate are switched, and the roller sieves that have completed one brushing operation are separated from the substrate, thereby realizing the periodic replacement of the roller brushes 23. The replaced roller brushes 23 continue to clean the substrate, while the replaced roller brushes 23 continue to rotate and contact the comb tooth plate 2 during rotation, thereby cleaning the replaced roller brushes 23. Since the driving wheel 26 close to the movement path of the substrate has a large diameter and the driving wheel 26 far from the movement path of the substrate has a small diameter, when the rotation speed of the drive motor 28 is fixed, the angular velocities of the multiple driving wheels 26 are the same and the linear velocities are different. Therefore, the rotation speeds of the multiple transmission wheels 27 meshing with the driving wheels 26 are different. When the transmission wheel 27 fixedly connected to the roller brush 23 is docked with the driving wheel 26 close to the substrate, the rotation speed of the roller brush 23 is relatively high at this time. And when the transmission wheel 27 fixed on the roller brush 23 is docked with the driving wheel 26 far from the substrate, the rotation speed of the roller brush 23 is relatively low at this time. Therefore, in practical applications, when the roller brush 23 is in contact with the substrate, it rotates at a high speed to clean the substrate. And when the roller brush 23 cooperates with the comb tooth plate 2 to clean the impurities between the bristles, its rotation speed is reduced, which can not only achieve the impurity cleaning effect but also reduce the probability of the bristles being broken or detached due to excessive force. In other embodiments of the present application, the rotation speed when the roller brush 23 contacts the substrate and the comb tooth plate 2 can also be adjusted by replacing the driving wheels 26 of different sizes or adjusting the angle of the roller brush unit, thereby enhancing the brushing effect of the roller brush unit on the substrate;

[0062] In the present invention, by installing multiple roller brushes 23 on a single roller brush unit, on the one hand, through the periodic replacement of the roller brushes 23, it is possible to prevent impurities from accumulating and adhering excessively between the bristles of the roller brushes 23, thereby reducing the phenomenon of scratching the surface of the substrate by the roller brushes 23. On the other hand, the brushing operation of the roller brushes 23 on the substrate is separated from the cleaning operation of the roller brushes 23, which facilitates adjusting the rotation speed of the roller brushes 23, enabling the drum sieve to perform brushing and self-cleaning operations at different rotation speeds respectively. This can not only enhance the flexibility of use of the roller brush unit but also ensure the brushing effect of the roller brushes 23 on the substrate and reduce the probability of scratching the substrate.

[0063] As a preferred embodiment of the present invention, it further includes an anti-diffusion component. The anti-diffusion component is installed in the cleaning tank 1 and is used to prevent the impurities on the substrate from diffusing in the cleaning tank 1.

[0064] The anti-diffusion component includes a flow-blocking box body 3. The flow-blocking box body 3 is fixedly installed in the cleaning tank 1, and the brushing components are all installed in the flow-blocking box body 3. Both ends of the flow-blocking box body 3 are open, and the movement path of the substrate passes through the flow-blocking box body 3.

[0065] A filter 31 and a circulation pump 32. The filter 31 and the circulation pump 32 are both installed on the cleaning tank 1. The input end of the circulation pump 32 is conductively connected to the inner cavity of the flow-blocking box body 3. The output end of the circulation pump 32 extends into the filter 31, and the output end of the filter 31 is conductively connected to the cleaning tank 1.

[0066] In the cleaning operation of the substrate, since the brushing operation is carried out in the cleaning aqueous solution, during the process of friction between the bristles of the roller brush 23 and the substrate, the bristles themselves are deformed, which easily promotes the diffusion of impurities in the aqueous solution. After the impurities are dispersed in the cleaning aqueous solution, it is not only inconvenient to collect the impurities, but also causes pollution of the cleaning aqueous solution, resulting in an increase in the replacement frequency of the cleaning aqueous solution. Therefore, in the present invention, a diffusion prevention component is provided. During the actual installation of the equipment, the brushing unit is installed in the flow blocking box 3, and the flow blocking box 3 is installed on the cleaning pool 1. The two sides of the flow blocking box 3 are open, and the movement path of the substrate passes through the flow blocking box 3. In the substrate cleaning operation, the substrate is guided by the guide roller 12 and moves in the cleaning aqueous solution, being soaked by the cleaning aqueous solution, resulting in a decrease in the adhesion stability of oil stains, impurities, etc. on the substrate. Subsequently, the substrate enters the flow blocking box 3 through the opening on the flow blocking box 3 and, when moving in the flow blocking box 3, is successively brushed by multiple sets of roller brush units, causing the dirt to fall off and disperse in the cleaning aqueous solution in the flow blocking box 3. During this process, the circulation pump 32 is continuously started. The input end of the circulation pump 32 continuously extracts the cleaning aqueous solution in the flow blocking box 3 and pumps the cleaning aqueous solution into the filter 31. After the filter 31 filters the cleaning aqueous solution, the solid impurities are intercepted, and the liquid cleaning aqueous solution is discharged here. On the one hand, the interception of the flow blocking box 3 causes the brushed-off impurities and dirt to be intercepted, preventing the impurities and dirt from spreading in the cleaning pool 1, thereby maintaining the clarity of the cleaning aqueous solution and enhancing the effect of rinsing the substrate after brushing. On the other hand, in cooperation with the negative pressure extraction operation of the circulation pump 32, the cleaning aqueous solution flows directionally, so the efficiency of collecting dirt is effectively improved.

[0067] As a preferred embodiment of the present invention, the diffusion prevention component further includes a pre-rinsing box 4. The pre-rinsing box 4 is fixedly installed in the cleaning pool 1. The two ends of the pre-rinsing box 4 are open, and the movement path of the substrate passes through the pre-rinsing box 4. The top end of the pre-rinsing box 4 is above the liquid level of the cleaning pool 1. The input end of the circulation pump 32 is connected in communication with the inner cavity of the pre-rinsing box 4.

[0068] Since the adhesion stability of impurities and dirt on the substrate is different, in order to further enhance the effect of collecting dirt, by setting the pre-rinsing box 4, before the substrate enters the cleaning aqueous solution, the substrate first enters the pre-rinsing box 4 and contacts the cleaning aqueous solution in the pre-rinsing box 4, causing impurities such as floating ash and carbon powder with relatively low adhesion stability to fall off first in the pre-rinsing box 4. And the pre-rinsing box 4 is also connected in communication with the circulation pump 32, so the fallen impurities are also guided to the filter 31. Then, the pre-rinsed substrate enters the cleaning aqueous solution in the cleaning pool 1, is soaked by the cleaning aqueous solution, and then enters the flow blocking box 3 for brushing, further enhancing the effect of collecting dirt and reducing the degree of diffusion of impurities in the cleaning pool 1.

[0069] As a preferred embodiment of the present invention, a high-pressure pump 41 is fixedly installed on the cleaning tank 1. The input end of the high-pressure pump 41 is conductively connected to the output end of the filter 31. High-pressure water guns 42 are installed on both the pre-flushing box body 4 and the flow-blocking box body 3. The high-pressure water guns 42 are conductively connected to the output end of the high-pressure pump 41;

[0070] The high-pressure water guns 42 are all inclinedly installed with respect to the movement path of the substrate, and the jetting direction of the high-pressure water guns 42 is opposite to the movement direction of the substrate;

[0071] The setting of the high-pressure pump 41 continuously extracts the clean cleaning aqueous solution filtered by the filter 31, and after pressurization, pumps it into the pre-flushing box body 4 and the flow-blocking box body 3, and is guided by the high-pressure water guns 42 to be jetted onto the substrate. On the one hand, the impact of the high-pressure water enhances the impact effect on the dirt on the substrate, resulting in an increased probability of dirt shedding. On the other hand, the impact of the high-pressure water reduces the probability of impurities diffused in the cleaning aqueous solution adhering to the substrate again.

[0072] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
