Description

Technical Field

[0001] This application relates to the technical field of steel plate surface cleaning, and in particular to a steel plate surface cleaning device. Background Technology

[0002] In the container manufacturing industry, steel plates must be free of surface impurities such as rust, oil, and oxides before painting to ensure the coating adheres firmly. Impurity removal is a crucial step in the entire production line, directly impacting the quality of subsequent coating and the overall durability of the container. Currently, sandblasting machines are widely used in the industry for this process. Sandblasting machines use high-pressure air to propel abrasive particles at high speed onto the steel plate surface, effectively removing impurities through impact. This method achieves excellent cleaning results and the required surface cleanliness.

[0003] However, sandblasting machines have significant drawbacks. First, they generate tremendous noise during operation, often exceeding 90 decibels. This high-intensity noise not only disrupts the working environment and affects worker communication and concentration, but can also cause long-term damage to the hearing health of operators. Second, the sandblasting process produces a large amount of fine dust, which easily disperses and remains suspended in the air. Although sandblasting machines are typically equipped with dust collection devices on one side, such as dust hoods and ventilation systems, designed to collect and reduce dust, dust control is ineffective in practice. A large amount of dust still escapes, leading to a severe decline in workplace air quality, reduced visibility, and an increased risk of respiratory illnesses for workers. Utility Model Content

[0004] To address the problems of high noise levels and low dust collection efficiency in sandblasting machines, this application provides a steel plate surface cleaning device.

[0005] The steel plate surface cleaning device provided in this application adopts the following technical solution: A steel plate surface cleaning device includes a support frame, a conveying assembly, a brushing assembly, and a dust collection assembly. The conveying assembly is mounted on the support frame and is used to convey the steel plate. The brushing assembly includes a brushing drive motor and a brushing shaft, both of which are mounted on a support frame. The brushing drive motor drives the brushing shaft to rotate. The brushing shaft is used to brush away impurities from the surface of the steel plate and is equipped with plastic and metal brushes. The dust collection assembly includes a vacuum cleaner, a dust collection connecting pipe, and a dust collection box. The vacuum cleaner is mounted on one side of the support frame, and the dust collection box is mounted on the support frame. The dust collection box has a dust collection port, and the vacuum cleaner is connected to the dust collection box via the dust collection connecting pipe.

[0006] By adopting the above technical solution, the support frame provides a stable foundation for the entire device. The conveying assembly is responsible for the automatic feeding and output of the steel plates, realizing the continuity of the cleaning process. The brushing assembly drives the brushing shaft to rotate at high speed through the power output of the brushing drive motor. The plastic brushes and metal brushes set on the brushing shaft work synchronously. If only plastic brushes are used, the cleaning ability will decrease rapidly after the brushes wear down; if all metal brushes are used, although they are more durable, the cost is too high. This design combines the two, which ensures the cleaning effect while taking into account the equipment manufacturing cost and the service life of the brushes. The dust collection assembly uses the negative pressure generated by the vacuum cleaner to conduct the dust to the dust collection box through the dust collection connection pipe, which can promptly suck away the dust and impurities brushed off from the surface of the steel plate.

[0007] Preferably, the metal brushes and plastic brushes on the brush removal shaft are arranged in a spiral and side by side; the combined brush composed of the metal brushes and plastic brushes has two sections, and the two sections of the combined brush are symmetrically arranged on the brush removal shaft, with the spiral directions of the two sections of the combined brush being opposite.

[0008] By adopting the above technical solution, the metal and plastic brushes on the brush removal shaft are arranged in a spiral side-by-side, with the spiral directions of the two combined brush sections opposite. This structural design allows the axial forces generated by the two brush sections to cancel each other out when the brush removal shaft rotates at high speed, thereby significantly improving the smoothness of the brush removal shaft's operation and preventing axial movement. At the same time, the opposite spiral direction enables the brushed impurities to converge from both sides of the steel plate towards the central area, creating favorable conditions for the concentrated adsorption of subsequent dust collection components.

[0009] Preferably, two brushing shafts are provided, both of which are mounted on a support frame. The two brushing shafts are located above and below the steel plate, respectively. The brushing shaft located above the steel plate is used to brush away impurities on the upper surface of the steel plate, and the brushing shaft located below the steel plate is used to brush away impurities on the lower surface of the steel plate.

[0010] By adopting the above technical solution, two brushing shafts are set up and positioned on the upper and lower sides of the steel plate respectively, enabling simultaneous cleaning of the upper and lower surfaces of the steel plate. This layout allows the steel plate to complete double-sided cleaning in a single pass through the cleaning device.

[0011] Preferably, the dust collection assembly is provided in two sets, which are located above and below the steel plate, respectively. The dust collection port of the dust collection box located above the steel plate faces the upper surface of the steel plate, and the dust collection assembly located above the steel plate is used to adsorb the impurities brushed off the upper surface of the steel plate. A container is fixedly connected to the lower part of the support frame. The container is used to collect impurities brushed off the steel plate. The dust collection box located below the steel plate is set on the container, and the dust collection port of the dust collection box faces the inner bottom wall of the container.

[0012] By adopting the above technical solution, two sets of dust collection components are set up, corresponding to the upper and lower parts of the steel plate respectively, forming a complete dust collection system. The dust collection box located above the steel plate directly absorbs impurities brushed off from the upper surface; the dust collection box located below the steel plate works in conjunction with the container, which collects impurities falling from the lower surface, while the dust collection box below is specifically responsible for absorbing the collected material in the container, thereby achieving effective collection of all impurities generated during the cleaning process.

[0013] Preferably, the dust collection assembly located above the steel plate further includes a swing motor. The dust collection box of the dust collection assembly is rotatably mounted on the support frame, and the swing motor is mounted on the support frame. The swing motor is used to drive the dust collection box to swing back and forth.

[0014] By adopting the above technical solution, a swing motor is configured for the dust collection box located above the steel plate, enabling the dust collection box to swing back and forth. This motion characteristic allows the suction port to no longer be fixed in one position, but to periodically cover a wider surface area of ​​the steel plate, thereby expanding the effective range of a single adsorption and improving the ability to capture diffuse dust.

[0015] Preferably, the dust collection assembly located below the steel plate further includes a swing motor. The dust collection box of the dust collection assembly is rotatably mounted on the side wall of the container. The swing motor is mounted on the side wall of the container and is used to drive the dust collection box of the dust collection assembly to swing.

[0016] By adopting the above technical solution, a swing motor is configured for the dust collection box located below the steel plate, causing the dust collection box to swing within the container. The swinging suction port can more effectively agitate and adsorb impurities deposited at the bottom of the container, preventing impurities from accumulating inside the container.

[0017] Preferably, the support frame further includes a height adjustment component for adjusting the distance between the brush shaft and the steel plate. The height adjustment component includes a rotating support block, an auxiliary support nut, and an auxiliary support screw. The support frame has a vertically formed waist-shaped groove. The rotating support block is mounted on the support frame by mounting bolts that pass through the waist-shaped groove. The auxiliary support nut is horizontally mounted on the support frame and is located below the rotating support block. The auxiliary support screw is vertically threaded onto the auxiliary support nut, and its end abuts against the lower end of the rotating support block.

[0018] By adopting the above technical solution, the height adjustment component achieves height positioning and fixation of the rotating support block through the waist-shaped groove and mounting bolts. The cooperation of the auxiliary support screw and auxiliary support nut provides bottom-up auxiliary support force to the positioned rotating support block, enhancing the rigidity and stability of the support, thereby ensuring that the brush removal shaft can operate stably at the adjusted working height and adapt to the cleaning needs of steel plates of different thicknesses.

[0019] Preferably, the conveying assembly includes a conveying motor and conveying shafts. Multiple conveying shafts are arranged along the length of the support frame. Each conveying shaft has a conveying cylinder coaxially arranged on it. Each end of the conveying shaft is provided with a conveying sprocket. A conveying chain is sleeved between two adjacent conveying sprockets. The conveying motor is mounted on the support frame, and the output shaft of the conveying motor is located at the end of one of the conveying shafts.

[0020] By adopting the above technical solution, the conveying assembly uses a conveyor motor to drive a single conveyor shaft, and transmits power to all parallel conveyor shafts through conveyor sprockets and conveyor chains, achieving synchronous rotation of multiple conveyor cylinders. This linkage mechanism ensures that the steel plate is subjected to uniform force and runs smoothly during conveying, and can be well coordinated with the cleaning action of the brushing assembly to ensure consistent and uniform cleaning results.

[0021] In summary, this application includes the following beneficial technical effects: This application addresses the problems of high noise and poor dust control in sandblasting machines in the prior art by employing mechanical brushing instead of sandblasting. The brushing assembly uses a brush drive motor to rotate the brush shaft, utilizing plastic and metal brushes to remove impurities from the steel plate surface, significantly reducing operating noise. A dust collection assembly generates negative pressure via a vacuum cleaner, which is transmitted to the dust collection box through a suction pipe. The dust collection box, driven by a swing motor, oscillates back and forth, increasing the suction range, improving dust collection efficiency, effectively improving air quality in the working environment, and reducing worker health risks. A container further collects impurities brushed off the underside of the steel plate, further enhancing dust control. A height adjustment assembly allows adjustment of the distance between the brush shaft and the steel plate to adapt to different working conditions and ensure cleaning effectiveness.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0031] This application discloses a steel plate surface cleaning device, referring to... Figures 1-2 The system includes a support frame 1, a conveying assembly 2, a brushing assembly 3, a dust collection assembly 4, and a height adjustment assembly 5, all of which are mounted on the support frame 1. The conveying assembly 2 is used to convey the steel plate, the brushing assembly 3 is used to brush away impurities from the steel plate, the dust collection assembly 4 is used to absorb the impurities brushed off the steel plate, and the height adjustment assembly 5 is used to adjust the distance between the brushing assembly 3 and the steel plate.

[0032] Reference Figures 1-3In this embodiment, two sets of conveying components 2 are arranged side by side along the length of the support frame 1. The brushing component 3 is arranged between the two sets of conveying components 2. One set of conveying components 2 is used to input the steel plate from the previous processing step to the brushing component 3, and the other set of conveying components 2 is used to input the steel plate from the brushing component 3 to the next processing step. This embodiment takes the set of conveying components 2 that inputs the steel plate to the brushing component 3 as an example. The conveying component 2 includes a conveying motor 21 and conveying shafts 22. Four conveying shafts 22 are arranged horizontally side by side along the length of the support frame 1, and the axis of each conveying shaft 22 is perpendicular to the length of the support frame 1. The conveyor shafts 22 are rotatably mounted on the support frame 1. Each conveyor shaft 22 is fixedly connected to a conveyor cylinder 221. One end of each conveyor shaft 22 is fixedly connected to a conveyor sprocket 222. A conveyor chain 23 is sleeved between two adjacent conveyor sprockets 222. The conveyor motor 21 is fixedly connected to the support frame 1. The end of the output shaft of the conveyor motor 21 is coaxially fixedly connected to the conveyor shaft 22 near the brush removal component 3.

[0033] Reference Figure 1 , Figure 3 and Figure 4 A brush removal bracket 11 is provided on the support frame 1, and the brush removal bracket 11 is vertically fixed to the support frame 1. In this embodiment, two brush removal brackets 11 are provided, and the two brush removal brackets 11 are arranged side by side along the width direction of the support frame 1. Two sets of brush removal components 3 are provided, and the two sets of brush removal components 3 are installed on the brush removal bracket 11 through height adjustment components 5, and are located on the upper and lower sides of the steel plate respectively, so as to remove impurities on the upper and lower surfaces of the steel plate. In this embodiment, four sets of height adjustment components 5 are provided, of which two sets of height adjustment components 5 are respectively provided at the upper end of the two brush removal brackets 11, and the two sets of height adjustment components 5 are located on the same side of the brush removal bracket 11, and the two sets of height adjustment components 5 are used to support the brush removal components 3 located above the steel plate. The other two sets of height adjustment components 5 are also provided on the brush removal bracket 11, respectively located below the aforementioned two sets of height adjustment components 5, and located on the other side of the brush removal bracket 11, so as to support the brush removal components 3 located below the steel plate.

[0034] Reference Figure 1 , Figure 3 and Figure 4 This embodiment uses a brush removal assembly 3 mounted above a steel plate as an example. The brush removal assembly 3 includes a brush removal drive motor 31 and a brush removal shaft 32. The brush removal shaft 32 is rotatably mounted on the brush removal bracket 11 via two sets of height adjustment components 5. The brush removal shaft 32 is equipped with brushes, and its axis is parallel to the axis of the conveying shaft 22. The brush removal drive motor 31 is fixedly connected to the support frame 1, and its output shaft is coaxially fixedly connected to the end of the brush removal shaft 32. The brush removal drive motor 31 is used to drive the brush removal shaft 32 to rotate.

[0035] Reference Figure 1 and Figure 5 This embodiment uses one set of height adjustment components 5 and one brush removal bracket 11 as an example for illustration. The height adjustment component 5 includes a rotating support block 51, an auxiliary support nut 53, and an auxiliary support screw 54. A waist-shaped groove 111 is vertically formed on the side wall of the brush removal bracket 11. The rotating support block 51 is positioned on the side wall of the brush removal bracket 11 by mounting bolts 52, and the mounting bolts 52 also pass through the waist-shaped groove 111. The auxiliary support nut 53 is horizontally fixedly connected to the side wall of the brush removal bracket 11, and the auxiliary support nut 53 is also located at the lower end of the rotating support block 51. The auxiliary support screw 54 is vertically threadedly connected to the auxiliary support nut 53, and the upper end of the auxiliary support screw 54 abuts against the lower end of the rotating support block 51.

[0036] Reference Figures 1-3 Conveying assembly 2 is responsible for the continuous conveying of the steel plate. The conveying motor 21 is started, driving the conveying shaft 22, which is coaxially and fixedly connected to its output shaft, to rotate. This conveying shaft 22 transmits power to the other parallel conveying shafts 22 via a conveying sprocket 222 fixed at its end and a sleeved conveying chain 23, thereby causing all conveying shafts 22 and the conveying cylinders 221 on them to rotate synchronously. This linkage mechanism ensures that the steel plate is smoothly and continuously fed from the previous processing step into the working area of ​​the brushing assembly 3. After the steel plate has undergone surface cleaning, another set of conveying assemblies 2, operating on the same principle, reliably outputs the steel plate from the brushing area to the next processing step.

[0037] Reference Figures 1-3 While the conveying assembly 2 is conveying the steel plate, the brushing assembly 3 cleans the surface of the steel plate. Two sets of brushing assemblies 3, positioned above and below the steel plate, start simultaneously, each driven by its own brushing drive motor 31, which drives the brushing shaft 32 to rotate at high speed. The high-speed rotating brushing shaft 32 causes the brushes on it to mechanically brush against the surface of the steel plate, thereby continuously removing impurities such as rust, oil, and oxides adhering to the surface during the steel plate conveying process. Reference Figure 1 and Figure 5The height adjustment component 5 is used to adjust the working position of the brush removal component 3. When it is necessary to adjust the height of the brush removal shaft 32, the operator first loosens the mounting bolt 52 that fixes the rotating support block 51 at the position of the waist-shaped groove 111 of the brush removal bracket 11. At this time, the rotating support block 51 can move freely along the waist-shaped groove 111. After the operator raises or lowers the rotating support block 51 to the required height, the mounting bolt 52 is tightened again to achieve the positioning of the rotating support block 51. Finally, the auxiliary support screw 54 is rotated so that the upper end of the auxiliary support screw 54 abuts against the lower end of the rotating support block 51, thereby providing auxiliary support and enhancing the positioning stability of the positioned rotating support block 51.

[0038] Reference Figure 1 and Figure 4 In this embodiment, the two brushing shafts 32 rotate in opposite directions. Specifically, when the steel plate is conveyed along the forward direction, the brushing shaft 32 located above the steel plate and the brushing shaft 32 located below the steel plate rotate in opposite directions. Simultaneously, the direction of the frictional force generated when the brushes of each brushing shaft 32 contact the surface of the steel plate is opposite to the forward direction of the steel plate. This arrangement aims to enhance the cleaning effect of the brushing assembly 3 on the surface of the steel plate, thereby efficiently removing impurities. The brushes on the brushing shafts 32 are plastic brushes 321 and metal brushes 322, arranged spirally along the axial direction of the brushing shafts 32, with the plastic brushes 321 and metal brushes 322 arranged side-by-side. This combination of brushes optimizes cleaning efficiency and reduces costs. The plastic brushes 321 and metal brushes 322 work synchronously. If only plastic brushes 321 are used, the cleaning ability will rapidly decrease after the brushes wear down; if only metal brushes 322 are used, although more durable, the cost is too high. This design combines two elements to ensure cleaning effectiveness while balancing equipment manufacturing costs and brush lifespan. The combined brush, consisting of a plastic brush 321 and a metal brush 322, has two sections on the brushing shaft 32, symmetrically arranged along the shaft. Furthermore, the two sections of the combined brush have opposite spiral directions. Because of these opposite spiral directions, the axial forces generated by the two sections during the rotation of the brushing shaft 32 are in opposing directions, thus balancing the axial forces and effectively preventing axial movement of the brushing shaft 32 during operation. Simultaneously, this symmetrical and opposite spiral arrangement guides the brushed-off impurities from both sides of the steel plate along its width direction, guiding them to the central area of ​​the steel plate for collection and subsequent centralized suction and cleaning by the vacuuming components.

[0039] Reference Figure 2 and Figure 6A container 12 is fixedly connected to the support frame 1, and the container 12 is also located below the lower brushing shaft 32. The function of the container 12 is to collect the impurities brushed off the lower surface of the steel plate by the lower brushing shaft 32. The dust collection assembly 4 is set at the position where the steel plate is fed from the brushing assembly 3 to the next processing step into the conveying assembly 2. The dust collection assembly 4 includes a vacuum cleaner 41, a dust collection connecting pipe 42, a dust collection box 43, and a swing motor 44. Two sets of dust collection assemblies 4 are provided. One set of dust collection assemblies 4 is used to absorb the impurities brushed off the upper surface of the steel plate. Specifically, the vacuum cleaner 41 is vertically set on one side of the support frame 1, and the lower end of the vacuum cleaner 41 is fixedly connected to the ground. The dust collection box 43 is horizontally fixedly connected to the support frame 1, and the dust collection box 43 is located above the steel plate. The length direction of the dust collection box 43 is parallel to the axis of the conveying shaft 22. The dust collection box 43 is rotatably connected to the support frame 1 at both ends via a rotating connecting block 432. One end of the suction connecting pipe 42 is fixedly connected to the vacuum cleaner 41, and the other end is fixedly connected to the dust collection box 43. A suction port 431 is provided at the lower end of the dust collection box 43, facing the upper surface of the steel plate. A row of partition plates 4311 is fixedly connected to the suction port 431 of the dust collection box 43 along its length. The oscillating motor 44 is fixedly connected to the support frame 1, located on one side of the dust collection box 43, and the end of the output shaft of the oscillating motor 44 is coaxially fixedly connected to the rotating connecting block 432. The oscillating motor 44 drives the dust collection box 43 to oscillate back and forth, thereby increasing the suction range of the dust collection box 43.

[0040] Reference Figures 6-7 Another set of vacuuming components 4 is used to absorb impurities that fall onto the inner bottom wall of the container 12. Specifically, the component includes a vacuum cleaner 41 vertically mounted on one side of the support frame 1, with its lower end fixedly connected to the ground. The component also includes a vacuum chamber 43 horizontally fixedly connected to the container 12, located below the steel plate, with its length parallel to the axis of the conveyor shaft 22. Both ends of the vacuum chamber 43 are rotatably connected to the side wall of the container 12 via a rotating connecting block 432. One end of the vacuum connecting pipe 42 is fixedly connected to the vacuum cleaner 41, and the other end is fixedly connected to the vacuum chamber 43. The lower end of the vacuum chamber 43 has a vacuum port 431 facing the inner bottom wall of the container 12. A row of partition plates 4311 is fixedly connected to the vacuum port 431 along its length. The component includes a swing motor 44 fixedly connected to the side wall of the container 12. The swing motor 44 is located on one side of the dust collection box 43, and the end of the output shaft of the swing motor 44 is coaxially fixedly connected to the rotating connecting block 432. The swing motor 44 is used to drive the dust collection box 43 to swing back and forth, thereby increasing the suction range of the dust collection box 43.

[0041] Reference Figure 2 , Figure 6 and Figure 7 When the vacuum cleaner assembly 4 is working, both sets of vacuum cleaner assemblies 4 start simultaneously. After the vacuum cleaner 41 is powered on, the powerful suction generated is transmitted to the inside of the vacuum chamber 43 through the vacuum connection pipe 42, thereby forming a stable negative pressure area inside the vacuum chamber 43. For the vacuum cleaner assembly 4 located above the steel plate, this negative pressure drives the airflow near the suction port 431 to carry the impurities brushed off from the surface of the steel plate into the vacuum chamber 43 quickly. At the same time, the oscillating motor 44 starts working, driving the vacuum chamber 43 to oscillate slowly and continuously around the rotation connection points at both ends as the axis. Through the oscillation of the vacuum chamber 43, the suction range of the vacuum chamber 43 is increased. A row of partitions 4311 fixed along the length of the suction port 431 divides the suction port 431 into multiple independent suction zones, which makes the negative pressure airflow more evenly distributed. The working principle is similar for the vacuum cleaner assembly 4 located in the container 12. The negative pressure generated by the vacuum cleaner 41 continuously draws the impurities that have gathered at the bottom of the container 12 into the vacuum box 43.

[0042] The implementation principle of the steel plate surface cleaning device in this application embodiment is as follows: The steel plate is smoothly conveyed to the brushing area by the conveying component 2. The brushing component 3 mechanically brushes the surface of the steel plate through the high-speed rotating brushing shaft 32 to remove rust, oil, and oxides. The plastic brush 321 and metal brush 322 on the brushing shaft 32 are arranged in a spiral shape, and the spiral directions of the two combined brushes are opposite, balancing the axial force and guiding impurities to gather towards the center. The height adjustment component 5 adjusts the distance between the brushing shaft 32 and the steel plate by adjusting the position of the rotating support block 51 at the waist-shaped groove 111 and using the auxiliary support screw 54 for auxiliary fixation. The dust collection component 4 generates negative pressure through the vacuum cleaner 41, which is transmitted to the dust collection box 43 through the dust collection connecting pipe 42. The dust collection box 43 swings back and forth under the drive of the swing motor 44, so that the suction port 431 can cover a larger area, effectively increasing the adsorption range. The separator 4311 ensures that the negative pressure airflow is evenly distributed, effectively adsorbing the impurities brushed off. The suction component 4 located below sucks away the impurities collected in the container 12.

[0043] This application uses mechanical brushing instead of sandblasting, which reduces operating noise; the dust collection component 4 drives the dust collection box 43 to swing back and forth through the swing motor 44, which increases the adsorption range, improves dust collection efficiency, improves the air quality of the working environment, and reduces the health risks to workers.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
