Description

Technical Field

[0001] This application relates to the field of metal sheet processing technology, and in particular to a water washing device for etching metal sheets. Background Technology

[0002] Metal sheet, a thin metal plate made from steel or stainless steel as the base material and processed through heat treatment, precision grinding, etching, and other techniques, typically possesses characteristics such as high precision, high strength, and high toughness. It is mainly used in fields such as electronic instruments, mold manufacturing, precision machinery, and hardware parts, serving as a key industrial consumable or structural component. In the processing of metal steel sheets, etching is a common method used to selectively remove material from the surface of the sheet. This allows for the creation of complex patterns and microstructures, surface treatment and functionalization, and dimensional control. Water washing equipment, used to remove residual etching solution from the surface and crevices of the etched metal steel sheet, plays a crucial role in ensuring the quality of subsequent processes.

[0003] An existing technology provides a washing device for etching metal steel sheets, comprising a main body, a conveying mechanism, and two spraying mechanisms. The conveying mechanism horizontally transports the etched metal steel sheets into the main body. The two spraying mechanisms are located inside the main body, on the upper and lower sides of the metal steel sheets, respectively, and are used to spray washing liquid onto the upper and lower surfaces of the metal steel sheets. In use, the conveying mechanism horizontally transports the etched metal steel sheets into the main body, and then the two spraying mechanisms spray washing liquid onto the upper and lower surfaces of the metal steel sheets, respectively, thereby achieving washing. After washing, the conveying mechanism outputs the metal steel sheets out of the main body for drying.

[0004] Regarding the aforementioned technologies, since the existing conveying mechanism can only horizontally convey the metal steel sheet into the machine body, the upper surface of the metal steel sheet inside the machine body remains in a horizontal state. This increases the amount of washing liquid sprayed out and left on the upper surface of the metal steel sheet, thereby increasing the probability that solid impurities dissolved in the washing liquid will remain on the surface of the metal steel sheet during subsequent drying, thus reducing the processing effect on the metal steel sheet. Summary of the Invention

[0005] In order to reduce the amount of washing liquid remaining on the surface of the metal steel sheet after spraying, this application provides a washing device for etching metal steel sheets.

[0006] This application provides a water washing device for etching metal steel sheets, which adopts the following technical solution: A water washing device for etching metal steel sheets includes a device body and a spraying mechanism. The spraying mechanism is used to spray washing liquid onto the surface of the metal steel sheets inside the device body. The device body is characterized by having a conveying mechanism and a rotating mechanism. The rotating mechanism includes a rotating frame and a rotating assembly. The end of the rotating frame has an opening for the metal steel sheet to enter. The conveying mechanism is used to convey the metal steel sheet into the opening of the rotating frame. The rotating frame is rotatably connected to the device body. The rotating assembly is used to drive the rotating frame to rotate.

[0007] By adopting the above technical solution, compared with the prior art, the upper surface of the metal steel sheet inside the machine body is continuously in a horizontal state, which increases the probability that the sprayed washing liquid remains on the upper surface of the metal steel sheet, and increases the probability that the solid impurities dissolved in the washing liquid will remain on the surface of the metal steel sheet during subsequent drying, thereby reducing the processing effect on the metal steel sheet. This application, by setting the rotating mechanism, enables the rotating component to drive the rotating frame to rotate after the conveying mechanism transports the metal steel sheet into the opening of the rotating frame, thereby causing the rotating frame to tilt or be in a vertical state. This allows the residual washing liquid on the surface of the metal steel sheet after spraying to flow down in the tilted or vertical direction, thereby reducing the amount of sprayed washing liquid remaining on the upper surface of the metal steel sheet, thereby reducing the probability that the solid impurities dissolved in the washing liquid will remain on the surface of the metal steel sheet during subsequent drying, thus ensuring the processing effect on the metal steel sheet, and also ensuring the washing effect.

[0008] Preferably, the conveying mechanism includes a clearance frame and a clearance component. Two clearance frames are provided, located on opposite sides of the rotating frame along the conveying direction of the metal sheet. The sides of the clearance frames that are far apart from each other are rotatably connected to the main body of the device. The clearance component is used to drive each clearance frame to rotate. Each clearance frame is provided with several clearance rollers. Each clearance roller is used to abut against the bottom of the metal sheet on the rotating frame and is rotatably connected to the corresponding clearance frame.

[0009] By adopting the above technical solution, the setting of the avoidance frame and the avoidance component enables the avoidance roller on the avoidance frame to support the metal steel sheet in the conveying state, and when the rotating frame rotates, the avoidance component can drive the avoidance frame to rotate, thereby enabling the avoidance frame to give way to the rotating frame, reducing the probability of the avoidance frame interfering with the rotation of the rotating frame, and thus enabling the rotating frame to rotate smoothly, ensuring the tilting and rotation effect of the metal steel sheet.

[0010] Preferably, the avoidance component includes a first linkage frame and a second linkage frame, one end of which is rotatably connected to the rotating frame, and the other end is rotatably connected to the two avoidance frames respectively.

[0011] By adopting the above technical solution, the arrangement of the first linkage frame and the second linkage frame enables the two avoidance frames to rotate when the rotating frame rotates. This allows the rotating frame to drive the avoidance frames through the first and second linkage frames, effectively realizing the linkage between the avoidance frames and the rotating frame. As a result, the avoidance frames can be driven without additional active components, thus reducing the probability of the avoidance frames accidentally interfering with the rotation of the rotating frame due to the failure of active components, and ensuring the smooth rotation of the rotating frame.

[0012] Preferably, the rotating frame is further provided with a limiting mechanism, which includes a limiting frame and a driving member. The limiting frame is located on the side of the rotating frame along its own width direction and close to the first linkage frame. The limiting frame is slidably connected to the rotating frame. The driving member is used to drive the limiting frame to slide so that after sliding, the limiting frame is located on the displacement path of the metal steel sheet on the rotating frame.

[0013] By adopting the above technical solution and setting the limiting mechanism, when the rotating frame rotates, the driving component can drive the limiting frame to slide, thereby causing the limiting frame to gradually move onto the displacement path of the metal steel sheet, thus hindering the displacement of the metal steel sheet relative to the rotating frame, reducing the probability of the metal steel sheet accidentally slipping off during the rotation of the rotating frame, thereby ensuring the rotation effect of the metal steel sheet, and thus ensuring the water washing effect of the metal steel sheet.

[0014] Preferably, the driving component includes a driving frame, one end of which is rotatably connected to the limiting frame, and the other end is rotatably connected to the second linkage frame or the first linkage frame.

[0015] By adopting the above technical solution and configuring the drive frame, during the rotation of the rotating frame, which causes the first and second linkage frames to move, the second linkage frame or the first linkage frame can drive the drive frame to move, thereby causing the drive frame to drive the limit frame to slide, realizing the linkage between the rotating frame and the limit frame. This effectively saves the active components required to drive the limit frame to slide, thereby reducing the overall weight of the rotating frame and facilitating the drive of the rotating frame's rotation.

[0016] Preferably, the rotating frame is rotatably connected to the device body at its center along its width direction, one end of the first linkage frame and the second linkage frame are rotatably connected to the rotating frame on the same side along its width direction, and the other end of the first linkage frame is rotatably connected to the rotating frame closest to it, and the other end of the second linkage frame is rotatably connected to another rotating frame.

[0017] By adopting the above technical solution, the first and second linkage frames are positioned so that their rotational connections with the rotating frame are located on the same side of the rotating frame. This allows the rotating frame to drive the two clearance frames to rotate to a suitable angle via the first and second linkage frames, effectively reducing the probability of interference with the rotating frame due to insufficient rotation angle of the clearance frames. This ensures smooth driving of the rotating frame, enabling it to smoothly drive the metal steel sheet to rotate to a vertical state.

[0018] Preferably, each of the avoidance frames is provided with a rotating component, and each of the rotating components is used to drive each of the avoidance rollers on the corresponding avoidance frame to rotate.

[0019] By adopting the above technical solution, the rotating component is configured to drive the avoidance roller on the corresponding avoidance frame to rotate, thereby ensuring the conveying effect of the metal steel sheet when the metal steel sheet is being conveyed.

[0020] Preferably, the number of spraying mechanisms is set to several, and all of them are located at the top of the inner cavity of the device body. The spraying mechanisms are respectively located on opposite sides of the rotating frame after rotation, and the spraying ends are all facing the metal steel sheet on the rotating frame after rotation.

[0021] By adopting the above technical solution and setting up several spraying mechanisms, it is possible to effectively spray both the upper and lower surfaces of the metal steel sheet, thereby improving the spraying efficiency of the metal steel sheet and ensuring the water washing efficiency of the metal steel sheet.

[0022] Preferably, the device body is further provided with an adjustment mechanism, which includes an adjustment frame and an adjustment component. The adjustment frame is rotatably connected to the device body, and the adjustment component is used to drive the adjustment frame to rotate. The spraying mechanism is disposed on the adjustment frame.

[0023] By adopting the above technical solution, the adjustment mechanism is designed so that the adjustment component can drive the adjustment frame to rotate, thereby adjusting the spray angle of the spray mechanism on the adjustment frame. This allows the washing liquid sprayed by the spray mechanism to fall onto multiple positions of the metal steel sheet on the rotating frame, thus ensuring the washing effect on the metal steel sheet.

[0024] Preferably, the conveying mechanism includes conveying rollers and conveying components. The conveying rollers are arranged in a plurality of positions and are located on opposite sides of the rotating frame. Each conveying roller is rotatably connected to the device body, and the conveying components are used to drive each conveying roller to rotate.

[0025] By adopting the above technical solution and configuring the conveying mechanism, the conveying components can drive each conveying roller to rotate, thereby enabling the conveying roller to effectively drive the metal steel sheet on it to move when rotating, thus realizing the conveying and support of the metal steel sheet and ensuring the conveying effect.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The rotating mechanism is designed so that after the conveying mechanism transports the metal steel sheet into the opening of the rotating frame, the rotating component can drive the rotating frame to rotate, causing the rotating frame to tilt or be in a vertical position. This allows the residual washing liquid on the surface of the metal steel sheet after spraying to flow down in the tilting or vertical direction, thereby reducing the amount of sprayed washing liquid remaining on the surface of the metal steel sheet. This reduces the probability of dissolved solid impurities in the washing liquid remaining on the surface of the metal steel sheet during subsequent drying, thus ensuring the processing effect of the metal steel sheet and also ensuring the washing effect. The arrangement of the clearance frame and clearance components allows the clearance rollers on the clearance frame to support the metal steel sheet in the conveying state. When the rotating frame rotates, the clearance components can drive the clearance frame to rotate, thereby allowing the clearance frame to give way to the rotating frame, reducing the probability of the clearance frame interfering with the rotation of the rotating frame, and thus allowing the rotating frame to rotate smoothly, ensuring the tilting and rotation effect of the metal steel sheet. The limiting mechanism is designed so that when the rotating frame rotates, the driving component can drive the limiting frame to slide, thereby gradually moving the limiting frame onto the displacement path of the metal steel sheet. This prevents the metal steel sheet from moving relative to the rotating frame, reducing the chance of the metal steel sheet accidentally slipping off during the rotation of the rotating frame, thus ensuring the rotation effect of the metal steel sheet and the water washing effect of the metal steel sheet.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a water washing apparatus for etching metal steel sheets. (Refer to...) Figure 1 and Figure 2 The water washing device for etching metal steel sheets includes a device body 1 and a spraying mechanism 2. The spraying mechanism 2 sprays washing liquid onto the surface of the metal steel sheets inside the device body 1. The device body 1 also includes a conveying mechanism 3 and a rotating mechanism 4. The rotating mechanism 4 includes a rotating frame 41 and a rotating assembly 42. The end of the rotating frame 41 has an opening for the metal steel sheets to enter, and the conveying mechanism 3 conveys the metal steel sheets into the opening of the rotating frame 41. The rotating frame 41 is rotatably connected to the device body 1, and the rotating assembly 42 drives the rotating frame 41 to rotate.

[0034] Reference Figure 1 and Figure 2 The device body 1 is placed on the ground. The conveying mechanism 3 includes conveying rollers 31 and conveying components 32. Several conveying rollers 31 are arranged and located on opposite sides of the rotating frame 41 along its width direction and distributed along the length direction of the device body 1 to transport metal steel sheets outside the device body 1 into the device body 1. Both ends of each conveying roller 31 are rotatably connected to the device body 1 through bearings.

[0035] Reference Figure 1 and Figure 2 In this embodiment of the application, the conveying component 32 is configured as a combination of a reduction motor and a chain sprocket. The reduction motor is fixedly installed on the device body 1, and its output shaft is fixedly connected to the end of a conveying roller 31 via a coupling. Each conveying roller 31 is fitted with a sprocket, and the chain is fitted on each sprocket so as to transmit with each sprocket.

[0036] Reference Figure 1 and Figure 2The rotating frame 41 is rotatably connected to the device body 1 via a pin (which is fixedly connected to the rotating frame 41) at its midpoint along its width direction. In this embodiment, the rotating component 42 is configured as a geared motor, which is fixedly mounted on the device body 1, and its output shaft is fixedly connected to the pin on the rotating frame 41 via a coupling to drive the rotating frame 41 to rotate.

[0037] Reference Figure 2 The rotating frame 41 is frame-shaped, and both the top and bottom are hollow along the middle of its width. An opening is provided on one side of the rotating frame 41 along its width to allow metal steel sheets conveyed by the conveying roller 31 to enter.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The conveying mechanism 3 also includes a clearance frame 33 and a clearance member 34. There are two clearance frames 33, which are located on both sides of the rotating frame 41 along the conveying direction of the metal steel sheet (i.e., the width direction of the rotating frame 41 itself). The ends of the two clearance frames 33 that are far apart from each other are located on opposite sides of the width direction of the rotating frame 41, and are rotatably connected to the device body 1 by a pin. Neither of them is located directly below the rotating frame 41 or on the rotation path of the rotating frame 41.

[0039] Reference Figure 2 and Figure 3 Each clearance frame 33 is equipped with a rotating component 35 and several clearance rollers 36. Both ends of the clearance rollers 36 are rotatably connected to the corresponding clearance frame 33 via bearings, and they are evenly and equidistantly distributed along the width direction of the corresponding clearance frame 33. When the metal sheet on the rotating frame 41 is in a horizontal state, the top of each clearance roller 36 on the clearance frame 33 abuts against the bottom surface of the metal sheet to support it. The rotation of the clearance rollers 36 drives the metal sheet to move, thus achieving the conveying of the metal sheet.

[0040] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment of the application, each rotating component 35 is configured as a combination mechanism of a reduction motor and a chain sprocket. The reduction motor is fixedly installed on the device body 1, and its output shaft is fixedly connected to the end of a clearance roller 36 through a coupling, or driven by a gear set to a clearance roller 36. A sprocket is sleeved on each clearance roller 36, and a chain is sleeved on each sprocket to transmit with each sprocket.

[0041] Reference Figure 2 and Figure 3The avoidance component 34 includes a first linkage frame 341 and a second linkage frame 342. In this embodiment, there are two of each of the first linkage frame 341 and the second linkage frame 342, which are located on opposite sides of the rotating frame 41 along its own length direction (perpendicular to the metal sheet conveying direction). Each first linkage frame 341 and each second linkage frame 342 are located on the same side of the rotating frame 41 along its own width direction.

[0042] Reference Figure 2 and Figure 3 Each first linkage frame 341 has one end rotatably connected to the corresponding end of the rotating frame 41 via a pin, and the other end is inclined downwards and rotatably connected to the adjacent clearance frame 33 via a pin. The rotatable connection is located at the end of the clearance frame 33 closest to the other clearance frame 33. Each second linkage frame 342 is located between the corresponding first linkage frame 341 and the other clearance frame 33. One end is rotatably connected to the middle of the corresponding side of the rotating frame 41 via a pin, and the other end is inclined downwards and rotatably connected to the end of the other clearance frame 33 closest to the second linkage frame 342 via a pin.

[0043] Reference Figure 1 , Figure 2 and Figure 3 In the initial state, when the metal steel sheet on the rotating frame 41 is horizontal, both clearance frames 33 are located at the top of their own rotation paths, and the clearance rollers 36 on each clearance frame 33 abut against the bottom of the metal steel sheet. When the rotating assembly 42 drives the rotating frame 41 to rotate, the end of the rotating frame 41 causes each of the first linkage frames 341 and the second linkage frames 342 to rotate relative to itself, thereby causing the first linkage frames 341 and the second linkage frames 342 to drive the clearance frames 33 corresponding to them to rotate, so that the clearance frames 33 give way to the rotating frame 41, ensuring the smooth rotation of the rotating frame 41.

[0044] Reference Figure 2 and Figure 3 The rotating frame 41 is also provided with a limiting mechanism 5, which includes a limiting frame 51 and a driving member 52. The limiting frame 51 is located on one side of the rotating frame 41 along its own width direction and close to the first linkage frame 341, and is located at the end of that side of the rotating frame 41. The limiting frame 51 is slidably connected to the rotating frame 41 through a slide rail, and the sliding direction is the height direction of the rotating frame 41. In the initial state, the limiting frame 51 is located below the opening on the rotating frame 41.

[0045] Reference Figure 2 and Figure 3Each second linkage frame 342 has a bent portion 3421 extending from its top. The bent portion 3421 is integrally formed with the second linkage frame 342, and one end is bent downward and extended. In this embodiment, the number of driving members 52 is set to two, and they are respectively located at both ends of the limiting frame 51 along its own length direction. Each driving member 52 includes a driving frame 521. One end of each driving frame 521 is rotatably connected to the corresponding bent portion 3421 by a pin, and the other end is rotatably connected to the limiting frame 51 by a pin.

[0046] Reference Figure 2 and Figure 3 In the initial state, when the metal steel sheet on the rotating frame 41 is horizontal, the avoidance rollers 36 on each avoidance frame 33 abut against the bottom of the metal steel sheet, and the limiting frame 51 is located below the opening on the rotating frame 41. When the rotating assembly 42 drives the rotating frame 41 to rotate, the end of the rotating frame 41 causes each first linkage frame 341 and second linkage frame 342 to rotate relative to itself, thereby causing the second linkage frame 342 to drive the corresponding driving frame 521 to rotate relative to itself, thereby causing the driving frame 521 to drive the limiting frame 51 to slide, so that the limiting frame 51 gradually closes the opening on the rotating frame 41, thereby sliding onto the sliding path of the metal steel sheet on the rotating frame 41 and hindering the sliding of the metal steel sheet.

[0047] Reference Figure 2 and Figure 3 In other embodiments, one end of the drive frame 521 can be rotatably connected to the top of the first linkage frame 341 via a pin, and the other end can be rotatably connected to the limit frame 51 via a pin, so that the first linkage frame 341 drives the limit frame 51 to slide through the drive frame 521, thereby realizing the linkage between the first linkage frame 341 and the limit frame 51.

[0048] Reference Figure 1 , Figure 2 and Figure 4 The device body 1 is also equipped with two adjustment mechanisms 6. Each adjustment mechanism 6 includes an adjustment frame 61 and an adjustment component 62. The two adjustment frames 61 are located at the top of the inner cavity of the device body 1 and are located on opposite sides of the rotational connection of the rotating frame 41 along the width direction of the rotating frame 41. Each adjustment frame 61 is rotatably connected to the device body 1 by a pin (which is fixedly connected to the rotating frame 41).

[0049] Reference Figure 1 and Figure 4 In this embodiment of the application, the adjustment component 62 is configured as a geared motor. Each geared motor is fixedly installed on the device body 1, and the output shaft is fixedly connected to the corresponding adjustment frame 61 through a coupling to drive the rotation of the adjustment frame 61.

[0050] Reference Figure 4 The number of spraying mechanisms 2 is set to several. In this embodiment, the number of spraying mechanisms 2 is set to two, and they correspond one-to-one with two adjusting frames 61. In this embodiment, the spraying mechanism 2 is set to several spray heads. Each spray head is fixedly installed on the corresponding adjusting frame 61, and the spraying end is exposed at the end of the corresponding adjusting frame 61 near the other adjusting frame 61, and faces the metal steel sheet on the rotating frame 41 after rotation, so as to spray the washing liquid onto the surface of the metal steel sheet.

[0051] Reference Figure 1 and Figure 4 In this embodiment, the water inlet of each spray head is connected to a liquid storage tank via a hose. Each liquid storage tank is fixedly installed on the device body 1 and stores washing liquid inside. In this embodiment, the hose of the spray head may also be equipped with a water pump to extract the washing liquid from the liquid storage tank and introduce it into the spray head.

[0052] The implementation principle of a water washing device for etching metal steel sheets according to an embodiment of this application is as follows: when the rotating component 42 drives the rotating frame 41 to rotate, the end of the rotating frame 41 drives each first linkage frame 341 and second linkage frame 342 to rotate relative to itself, thereby causing the first linkage frame 341 and second linkage frame 342 to drive the corresponding clearance frame 33 to rotate, so that the clearance frame 33 makes way for the rotating frame 41, ensuring the smooth rotation of the rotating frame 41.

[0053] During this process, the second linkage frame 342 drives the corresponding drive frame 521 to rotate relative to itself, causing the drive frame 521 to slide along the limit frame 51. This causes the limit frame 51 to gradually close the opening on the rotating frame 41, thus sliding onto the sliding path of the metal sheet on the rotating frame 41 and obstructing its movement. Afterward, the spray head sprays washing liquid onto the surface of the metal sheet. During this process, the adjusting component 62 drives the adjusting frame 61 to rotate, thereby adjusting the spray angle.

[0054] 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.
