Description

Technical Field

[0001] This application relates to the field of metal plate processing technology, specifically a double-sided cleaning device for metal plates. Background Technology

[0002] In the production and processing of metal sheets, effective surface cleaning is a crucial step. Metal, as a lustrous, ductile material with good electrical and thermal conductivity, often accumulates dust, dirt, oil, and other impurities on its surface due to processing environment or storage conditions. If these impurities are not removed promptly, they will not only affect the quality of subsequent painting and coating processes but also reduce the cleanliness of the metal sheet's appearance. Therefore, metal sheet cleaning equipment has become an indispensable tool in the metal processing industry.

[0003] To meet the demand for efficient cleaning of metal sheets, various metal sheet cleaning equipment has been developed in existing technologies, especially equipment designed for simultaneous cleaning of both sides, which greatly improves cleaning efficiency. These devices typically use automated conveying mechanisms (such as conveyor belts and roller sets) to continuously transport the metal sheets, combined with cleaning components such as spray systems, brushes, or cleaning belts to simultaneously rinse and wipe the upper and lower surfaces of the metal sheets. Some equipment also features adjustable cleaning mechanisms designed according to the size and specifications of the metal sheets to accommodate cleaning needs of metal sheets of different areas and thicknesses. For example, by adjusting the spacing of the cleaning components or the effective cleaning area, the versatility of the equipment is enhanced.

[0004] Chinese utility model patent CN222766800U discloses a double-sided cleaning device for metal plates. It uses an active rotating shaft to drive a cleaning belt, achieving cleaning through full contact between the belt and the metal plate. A top water tank sprays cleaning water for rinsing, and an electric telescopic rod adjusts the effective cleaning area of ​​the belt to accommodate metal plates of different sizes. However, in practical applications, this type of cleaning equipment often faces insufficient conveying stability, especially for thin or vertically conveyed metal plates. Taking this patented device as an example, it relies solely on bottom guide wheels for support. When handling thin metal plates, the plates are prone to swaying or even tipping due to insufficient rigidity. Once the metal plate tilts or tipps, the cleaning mechanisms (such as the spray system and cleaning belt) cannot maintain uniform and effective contact with both sides of the plate, resulting in only rinsing or wiping a portion of the tilted surface. This severely affects the consistency and thoroughness of double-sided cleaning, making it difficult to meet the surface cleanliness requirements of high-precision metal processing.

[0005] Therefore, this application provides a double-sided cleaning device for metal plates to solve the above problems. Utility Model Content

[0006] This application provides a double-sided cleaning device for metal plates, which aims to solve the problems mentioned in the background art, such as the fact that existing double-sided cleaning devices for metal plates, especially thin plates, rely solely on bottom guide wheels for support, which can easily cause the metal plates to shake or tip over, thus preventing the rinsing mechanism from effectively rinsing both sides of the metal plate and affecting the double-sided cleaning effect.

[0007] To achieve the above objectives, this application provides the following technical solution: a double-sided cleaning device for metal plates, including a collection frame and guide wheels arranged in a straight line and rotatably disposed in the middle of the collection frame for supporting and guiding the metal plates; it also includes a support frame fixed to the top of the collection frame, two sets of brush rollers rotatably disposed on the inner side of the support frame, and a rinsing mechanism disposed on the support frame.

[0008] To prevent the metal plate from tilting excessively on the guide wheels, a correction mechanism is provided on the collecting frame at the feeding end of the metal plate. This correction mechanism includes a protective frame arranged opposite to the metal plate, a rubber roller rotatably mounted within the protective frame, and a drive motor fixedly installed at the bottom of one of the protective frames. The output end of the drive motor is fixedly connected to the bottom end of the rubber roller. Through the interaction of the relatively rotating rubber roller and the guide wheels, the position of the metal plate can be corrected vertically, effectively preventing the metal plate from shifting, shaking, or tipping during transport. This ensures the metal plate enters the support frame in a stable, upright position, guaranteeing that the rinsing mechanism and brush roller can evenly apply pressure to both sides of the metal plate, improving the consistency and thoroughness of double-sided cleaning. Simultaneously, the soft rubber roller will not scratch or damage the surface of the metal plate, protecting its appearance.

[0009] Preferably, two sets of brush rollers are arranged above the guide wheel, and each set has three brush rollers, which are rotatably mounted on the support frame at equal intervals. The two sets of brush rollers act on the left and right surfaces of the metal plate respectively, achieving simultaneous double-sided brushing and improving cleaning efficiency.

[0010] Preferably, the rinsing mechanism includes a water tank fixed to the top of the support frame. A filling pipe is connected to the top of the water tank, and a connecting pipe penetrating the support frame is connected to the bottom of the water tank. A solenoid valve is installed on the surface of the connecting pipe, and a spray pipe is connected to the bottom of the connecting pipe. The water tank can store sufficient cleaning water, which can be easily and promptly replenished via the filling pipe, ensuring the continuity of the cleaning process. The spray pipe at the bottom of the connecting pipe can evenly spray cleaning water onto the surface of the metal plate, and, in conjunction with the brushing action of the brush roller, thoroughly wash away the detached impurities, further improving the cleaning cleanliness. The solenoid valve can precisely control the on / off state and flow rate of the cleaning water, adjusting the spray volume according to the degree of contamination of the metal plate, saving water resources and reducing cleaning costs.

[0011] Preferably, a plastic drain pipe is connected to one side of the collection frame, and the inner side of the plastic drain pipe extends into the interior of the collection frame. The plastic drain pipe can promptly discharge the cleaning wastewater collected in the collection frame, preventing wastewater from accumulating inside the collection frame and preventing secondary pollution of the metal plate by the wastewater.

[0012] Preferably, for cleaning safety: two transparent plates are symmetrically fixedly connected to both sides of the support frame, with a gap between the two transparent plates.

[0013] Preferably, the transparent panel is made of high-strength acrylic sheet. The high-strength acrylic sheet provides excellent transparency, allowing operators to easily observe the cleaning process of the metal plates inside the support frame in real time, enabling timely detection and handling of any abnormalities.

[0014] Preferably, to facilitate adjustment of the distance between the two rubber rollers: a guide rail is fixedly connected to the side of the transparent plate away from the support frame; a slider fixedly connected to the protective frame is slidably mounted on the guide rail; an electric push rod is fixedly connected to the top of the support frame; the output end of the electric push rod passes through the support frame and is fixedly connected to a hinge seat; both ends of the hinge seat are hinged to hinge rods that are hinged to the two protective frames. Through the cooperation of the electric push rod, hinge seat, and hinge rods, the distance between the two rubber rollers can be easily adjusted to adapt to metal plates of different thicknesses, improving the versatility and flexibility of the equipment; the sliding cooperation between the guide rail and the slider provides guidance for the movement of the protective frame, ensuring that the two rubber rollers remain parallel during adjustment, ensuring a stable correction effect on the metal plate; the electric push rod drive method has a high degree of automation, precise adjustment, and saves effort, reducing the labor intensity of operators. When it is necessary to adjust the distance between the two rubber rollers, the electric push rod is activated. Its output end drives the hinge seat to move up and down. When the hinge seat moves, it pulls or squeezes the hinge rods at both ends. The hinge rods drive the two protective frames to move closer or further apart under the sliding cooperation of the slider and the guide rail, thereby changing the distance between the two rubber rollers to adapt to the correction needs of metal plates of different thicknesses.

[0015] This application utilizes a rubber roller that rotates relative to the guide wheel to vertically correct the position of the metal plate, effectively preventing it from shifting, swaying, or tipping during transport. This ensures the metal plate remains stable and upright as it enters the support frame, guaranteeing that the rinsing mechanism and brush roller can evenly apply pressure to both sides of the metal plate, thus improving the consistency and thoroughness of double-sided cleaning. Furthermore, the soft rubber roller will not scratch or damage the surface of the metal plate, protecting its appearance.

[0016] The transparent panel in this application is made of high-strength acrylic sheet, which has good transparency, allowing operators to observe the cleaning process of the metal plates inside the support frame in real time, and promptly detect and handle any abnormalities. The gap between the two transparent panels provides a passage for the metal plates to enter and exit without affecting their normal transport. The high-strength acrylic sheet is sturdy and can effectively block splashing water and impurities during the cleaning process, protecting the safety of operators and preventing external dust and other contaminants from entering the support frame and polluting the metal plates.

[0017] This application utilizes the combination of an electric push rod, a hinge seat, and a hinge rod to conveniently adjust the distance between two rubber rollers, adapting them to metal plates of varying thicknesses and improving the equipment's versatility and flexibility. The sliding cooperation between the guide rail and the slider provides guidance for the movement of the protective frame, ensuring that the two rubber rollers remain parallel during adjustment and guaranteeing a stable correction effect on the metal plate. The electric push rod drive method offers a high degree of automation, precise adjustment, and labor-saving features, reducing the operator's workload. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] Example 1

[0025] This embodiment provides a double-sided cleaning device for metal plates, such as... Figs. 1-3As shown, the cleaning equipment includes a collection frame 1 and guide wheels 2 arranged in a straight line and rotatably disposed in the middle of the collection frame 1 for supporting and guiding the metal plate; it also includes a support frame 3 fixed to the top of the collection frame 1, two sets of brush rollers 4 rotatably disposed on the inner side of the support frame 3, and a rinsing mechanism 5 disposed on the support frame 3; in order to prevent the metal plate from tilting excessively on the guide wheels 2, a correction mechanism 6 is provided on the collection frame 1 at the feeding end of the metal plate, the correction mechanism 6 includes a protective frame 61 disposed opposite to each other, a rubber roller 62 rotatably disposed in the protective frame 61, and a drive motor fixedly installed at the bottom of one of the protective frames 61, the output end of the drive motor being fixedly connected to the bottom end of the rubber roller 62. The relatively rotating rubber rollers 62, in cooperation with the guide wheels 2, can vertically correct the position of the metal plate, effectively preventing it from shifting, swaying, or tipping during transport. This ensures the metal plate remains stable and upright as it enters the support frame 3, guaranteeing that the rinsing mechanism 5 and the brush rollers 4 can evenly apply pressure to both sides of the metal plate, improving the consistency and thoroughness of double-sided cleaning. Simultaneously, the soft rubber rollers 62 will not scratch or damage the metal plate surface, protecting its appearance. The metal plate is placed on the guide wheels 2 and enters between the two rubber rollers 62. The drive motor rotates the rubber rollers 62, and the friction between the rubber rollers 62 and the metal plate surface drives the metal plate to be smoothly transported along the guide wheels 2. During transport, the rubber rollers 62 on both sides clamp and limit the metal plate from the horizontal direction, counteracting any potential offset forces and ensuring the metal plate always maintains the correct transport path.

[0026] Two sets of brush rollers 4 are arranged above the guide wheels 2, with three brush rollers in each set. The three brush rollers 4 are equidistantly rotated on the support frame 3. The two sets of brush rollers 4 act on the left and right surfaces of the metal plate respectively, achieving simultaneous double-sided brushing and improving cleaning efficiency. Driven by the guide wheels 2 and rubber rollers 62, the metal plate enters between the two sets of brush rollers 4. Driven by their internal motors, the brush rollers 4 rotate, and the bristles on their surfaces contact and rub against the upper and lower surfaces of the metal plate. Through mechanical friction, impurities on the surface of the metal plate are peeled off, laying the foundation for the subsequent rinsing steps of the rinsing mechanism 5 and ensuring that impurities are thoroughly removed. The brush roller 4 consists of a roller motor and a brush cylinder fixedly sleeved outside the roller motor.

[0027] The rinsing mechanism 5 includes a water tank 51 fixed to the top of the support frame 3. A filling pipe 52 is connected to the top of the water tank 51, and a connecting pipe 53 penetrating the support frame 3 is connected to the bottom of the water tank 51. A solenoid valve 54 is installed on the surface of the connecting pipe 53, and a spray pipe 55 is connected to the bottom of the connecting pipe 53. The water tank 51 can store sufficient cleaning water, which can be easily and promptly replenished through the filling pipe 52 to ensure the continuity of the cleaning process. The spray pipe 55 at the bottom of the connecting pipe 53 can evenly spray cleaning water onto the surface of the metal plate. Combined with the brushing action of the brush roller 4, it thoroughly washes away the detached impurities, further improving the cleaning cleanliness. The solenoid valve 54 can precisely control the on / off state and flow rate of the cleaning water, adjusting the spray volume according to the degree of contamination of the metal plate, saving water resources and reducing cleaning costs. Cleaning water is injected into the water tank 51 through the filling pipe 52. When the metal plate enters the rinsing area, the solenoid valve 54 is opened. The cleaning water in the water tank 51 flows into the spray pipe 55 through the connecting pipe 53. The spray pipe 55 sprays the cleaning water evenly on the left and right surfaces of the metal plate at a certain pressure, rinsing the metal plate after it has been brushed by the brush roller 4, so that impurities are removed from the surface of the metal plate with the water flow, thus achieving the cleaning purpose.

[0028] A plastic drain pipe 11 is connected to one side of the collection frame 1, and the inner side of the plastic drain pipe 11 extends into the interior of the collection frame 1. The plastic drain pipe 11 can promptly discharge the cleaning wastewater collected in the collection frame 1, preventing wastewater from accumulating inside the collection frame 1 and preventing secondary pollution of the metal plate by wastewater. The wastewater generated during the cleaning process collects to the bottom of the collection frame 1 under the action of gravity. Since the plastic drain pipe 11 is connected to one side of the collection frame 1 and extends into its interior, the wastewater can flow out of the equipment naturally through the plastic drain pipe 11, realizing timely discharge of wastewater and maintaining the normal operating environment inside the equipment.

[0029] Example 2

[0030] Unlike Embodiment 1, for cleaning safety, two transparent plates 7 are symmetrically fixed to both sides of the support frame 3, with a gap between the two transparent plates 7. The transparent plates 7 are made of high-strength acrylic sheets. The high-strength acrylic sheets 7 have good transparency, allowing operators to observe the cleaning process of the metal plates inside the support frame 3 in real time, promptly identify and address any abnormalities; the gap between the two transparent plates 7 provides a passage for the metal plates to enter and exit without affecting their normal transport; the high-strength acrylic sheets are sturdy and effectively block splashing water and impurities during cleaning, protecting operator safety and preventing external dust from entering the support frame 3 and contaminating the metal plates. The transparent plates 7 are fixed on both sides of the support frame 3 to form a relatively enclosed cleaning space. During the cleaning process of the metal plate, splashing water and impurities are blocked by the transparent plates 7 and cannot splash out of the equipment. Through the transparency of the transparent plates 7, the operator can clearly observe the conveying status of the metal plate in the support frame 3, the brushing situation of the brush roller 4, and the spraying effect of the rinsing mechanism 5. The metal plate enters and exits the support frame 3 through the gap between the two transparent plates 7 to ensure that the cleaning process proceeds smoothly.

[0031] Example 2

[0032] Unlike Embodiment 1, to facilitate adjustment of the distance between the two rubber rollers 62: a guide rail 8 is fixedly connected to the side of the transparent plate 7 away from the support frame 3, and a slider 81 fixedly connected to the protective frame 61 is slidably mounted on the guide rail 8. An electric push rod 82 is fixedly connected to the top of the support frame 3, and the output end of the electric push rod 82 passes through the support frame 3 and is fixedly connected to a hinge seat 83. Both ends of the hinge seat 83 are hinged to hinge rods 84 that are hinged to the two protective frames 61. Through the cooperation of the electric push rod 82, the hinge seat 83, and the hinge rods 84, the distance between the two rubber rollers 62 can be easily adjusted to adapt to metal plates of different thicknesses, improving the versatility and flexibility of the equipment. The sliding cooperation between the guide rail 8 and the slider 81 provides guidance for the movement of the protective frame 61, ensuring that the two rubber rollers 62 remain parallel during the adjustment process, ensuring a stable correction effect on the metal plate. The electric push rod 82 has a high degree of automation, precise adjustment, and saves effort, reducing the labor intensity of operators. When it is necessary to adjust the distance between the two rubber rollers 62, the electric push rod 82 is activated, and its output end drives the hinge seat 83 to move up and down. When the hinge seat 83 moves, it pulls or squeezes the hinge rods 84 at both ends. The hinge rods 84 drive the two protective frames 61 to move closer or further apart under the sliding cooperation of the slider 81 and the guide rail 8, thereby changing the distance between the two rubber rollers 62 to adapt to the correction requirements of metal plates of different thicknesses.
