Description

Technical Field

[0001] This invention relates to the field of material corrosion resistance testing technology, specifically to a corrosion resistance testing device and method based on corrosion foil. Background Technology

[0002] Corrosion resistance testing equipment for etched foil is mainly used to evaluate the corrosion resistance of etched foil for aluminum electrolytic capacitors under conditions such as electrolyte, moisture, acid and alkali environments.

[0003] Referring to Chinese Patent Publication No. CN120142138A, a corrosion resistance testing device and method for etched foil processing are disclosed. The device includes a testing chamber with an exhaust mechanism at its upper end, an ultraviolet lamp at the top of the inner wall of the chamber, and a traction mechanism on one side of the chamber. In this invention, the atomized etching liquid more closely resembles corrosive media in the natural atmosphere, such as acid rain and salt spray, thus more realistically simulating complex corrosive environments. The synergistic effect of light, humidity, and the etching liquid allows for the study of various corrosion mechanisms, such as the superimposed effects of photo-induced oxidation corrosion and hydrothermal corrosion, closely approximating complex scenarios in practical applications. By comparing corrosion rates under conditions of no and no light, the promoting effect of ultraviolet light on material corrosion, such as photocatalytic oxidation, can be clearly identified. Comparison of the etching foil on the corrosion rack mechanism and the corrosion diffusion mechanism allows for the analysis of the influence of different humidity levels on corrosion types such as pitting corrosion and crevice corrosion.

[0004] Different types of corrosion foil require different treatment times in salt spray. Generally, only one type of corrosion foil can be treated in a concentrated manner at a time, and multiple types of corrosion foil cannot be treated simultaneously. Some corrosion foils require long salt spray treatment times, leaving ample space inside the salt spray chamber while other spaces remain empty, which is wasteful. Other test materials should be added or replaced without affecting the salt spray concentration and temperature inside the chamber. Furthermore, it is difficult to flip the corrosion foil during the testing process, making it difficult to complete the corrosion treatment on multiple sides of the corrosion foil. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a corrosion resistance testing device and method based on corrosion foil. By moving the material in and out of the box with the material placement plate, the two ends of the movement path serve as limiting points, facilitating the sealing and rotation of the material placement plate. After rotation, the material placement plate is adapted to an adaptive cleaning device, completing the material removal and cleaning in one go, which facilitates the replacement of materials.

[0006] Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: A corrosion resistance testing device based on corrosion foil, comprising: an outer box connected to a housing, wherein a plurality of channels are formed through one side of the housing and are connected to the outer box; each channel contains a material changing device configured to move horizontally and enter and exit the housing; a downward rotating baffle is provided below one end of each material changing device; and an adaptive cleaning device is provided on the side of each downward rotating baffle away from the housing. The adaptive cleaning device is used for... The material exchange device, used for absorbing liquid from the surface of materials after salt spray treatment, includes: a guide tube connected to the inner wall of a channel on its side; a sealing groove extending through the top of the guide tube and connected to a sealing plate; an outer guide rail connected to the inner wall of the guide tube; a material placement plate placed inside the guide tube; sliding cylinders connected to the middle of both sides of the material placement plate near the housing via rods; sliding cylinders slidably connected to the outer guide rails; a rotating plate connected to the other end of the guide tube; the rotating plate being adapted to the sliding cylinders; and a plug connected to the material placement plate via a socket.

[0007] Preferably, the top of the housing has a top groove, the bottom of which is connected to the top of the sealing groove. A first hydraulic cylinder is installed above the housing, the telescopic end of which is connected to a sealing plate. The bottom end of the sealing plate passes through the top groove and is inserted into the sealing groove. The sealing plate is used to move vertically under the drive of the telescopic end of the first hydraulic cylinder and to control the opening and closing of the sealing groove. A stepper motor and a fan are installed inside the outer box. The fixed end of the stepper motor is connected to the top wall of the outer box. The rotating end of the stepper motor is connected to a nut via a lead screw. The side of the nut is connected to a material changing device. The air outlet of the fan is connected to the material changing device via a first pipe. The air outlet of the fan is connected to an adaptive cleaning device via a second pipe.

[0008] Preferably, one end of the guide tube is connected to the inner wall of the channel, and the other end of the guide tube passes through the channel and extends into the outer box. A vertical hole is formed in the middle of the upper surface of the guide tube located in the outer box. A first sliding groove is formed on the inner wall of both sides of the guide tube. The outer guide rail is installed on the outside of the first sliding groove. A second sliding groove is formed on one side of the outer guide rail and the second sliding groove is connected to the first sliding groove. One end of the first sliding groove is connected to the rotating plate, and the other end of the first sliding groove is connected to the inner guide rail. Both the first and second sliding grooves are slidably connected to the slide cylinder. The material placement plate is a V-shaped plate. The end of the material placement plate away from the box is connected to the socket through a pressure sealing plate. A plug hole is formed on the top of the socket. The bottom end of the plug is inserted into the plug hole. The width of the pressure sealing plate is greater than the width of the sealing groove.

[0009] Preferably, the insert includes: an insert plate, which is inserted into an insertion hole; a moving rod is connected to the top of the insert plate via a connecting plate; a windward plate is connected to the top of the moving rod; the center of the top of the windward plate is connected to the top wall of the air duct via a spring; the windward plate is slidably connected to the inner wall of the air duct; an electromagnetic valve is connected to the side of the top of the air duct; the electromagnetic valve is connected to the fan via a first pipe; the windward plate is a bowl-shaped plate with its opening facing upward; and the top of the air duct is connected to the side of a nut via a side plate.

[0010] Preferably, the adaptive cleaning device includes: a bidirectional motor, the fixed end of which is connected to the bottom wall of the outer box, the rotating end of which is connected to a support plate, an air box above the support plate, the air box being connected to the inner wall of the outer box via a first plate, the air box being connected to several cylinders, each cylinder having an air cover connected to its inner wall near the air box via a second spring, the air cover being slidably connected to the inner wall of the cylinder, the air cover being connected to a moving plate via a push rod, each moving plate having a dehumidifying plate connected to its inner side, each moving plate having a flat plate above it, each flat plate having a guide plate connected to its inner top, the guide plate being connected to the inner wall of the outer box via a second plate, and the top of the air box being connected to a fan via a second pipe.

[0011] Preferably, the guide plate is an arc plate, the inner diameter of the guide plate gradually narrows in the vertical direction, the inner diameter of the top end of the guide plate is larger than the inner diameter of the bottom end of the guide plate, the inner diameter of the bottom end of the guide plate is equal to the inner diameter of the flat plate, the diameter of the flat plate is larger than the inner diameter of the flat plate, the inner side of the dehumidification plate is made of sponge material, and the dehumidification plate is used to gather and wrap the material under the action of thrust.

[0012] Preferably, after the material changing device moves to the box, when the slide cylinder moves to the end of the inner guide rail away from the outer box, the sealing plate is located directly below the sealing groove. The bottom end of the sealing plate passes through the top groove and the sealing groove and presses against the top of the sealing plate, sealing the channel. When the material changing device needs to be moved into the outer box, the material placement plate moves along the direction of the first slide groove. When the slide cylinder abuts against the rotating plate, one end of the material placement plate is placed on the lower rotating baffle. The rotation angle of the material placement plate is adjusted by controlling the height of the lower rotating baffle.

[0013] A method for detecting the corrosion resistance of corrosion-resistant foil includes a corrosion resistance testing device based on the foil. A channel is created in the chamber, allowing material to enter and exit. The channel is sealed by a sealing plate, controlling the connection or isolation between the chamber and the outside environment. A fan is turned on, and a solenoid valve is opened, increasing the pressure distribution within the air duct. The windward plate moves the insert plate downwards, engaging it with a socket. A screw rotates, and a nut sequentially moves the side plate, air duct, moving rod, insert plate, socket, and material placement plate towards the chamber. The material placement plate carries the material through the channel and into the chamber. The insert plate separates from the socket, and the insert plate does not obstruct the movement of the sealing plate. The sealing plate seals the channel. After some or all of the material has completed salt spray treatment, the corresponding solenoid valve is opened. The door, insert plate and socket are plugged in, the bidirectional motor reverses, the insert plate drives the material plate to move towards the outer box, the slide cylinder at one end of the material plate moves from the inner guide rail to the outer guide rail. When the material plate is moved out of the box, the sealing plate immediately moves down and seals the channel, the slide cylinder abuts against the rotating plate, and the material plate extends out from one end of the guide tube, thus completing the replacement or face changing of the material. One end of the material plate is placed on the lower rotating baffle. As the lower rotating baffle descends, the rod and the slide cylinder rotate relative to each other, one end of the material plate moves down, the material plate tilts, and the material slides down into the adaptive cleaning device. The air pressure inside the cylinder increases, and the air cover moves with the push rod, the moving plate and the dehumidifying plate towards the axis of the air box. The dehumidifying plate squeezes the material and wraps the material, absorbing the liquid on the surface of the material.

[0014] Beneficial Effects: This invention provides a corrosion resistance testing device and method based on corrosion foil. Compared with the prior art, it has the following beneficial effects: 1. The material moves in and out of the box with the material placement plate. The two ends of the movement path serve as limiting points, which facilitates the sealing and rotation of the material placement plate. After rotation, the material placement plate is adapted to an adaptive cleaning device. The material makes elastic contact with the dehumidifying plate set around the circumference, and the material is removed and cleaned in one go, which facilitates the replacement of the material.

[0015] 2. By constructing channels and matching sealing components and material changing devices, the treated materials can be replaced in a targeted manner. This allows materials with different salt spray treatment times to be processed in the same batch, and also enables the removal of materials after the salt spray treatment time has reached its limit, minimizing the impact on other materials still undergoing salt spray treatment. It offers wide adaptability. Furthermore, when surface salt spray treatment is required, the material can be quickly removed and the channel sealed. The channel has a small cross-section and a short opening time, reducing the impact of channel opening.

[0016] 3. By utilizing the material's own gravity to fall and tumble, the liquid in the material's depressions is allowed to flow out as much as possible. Then, through elasticity and plasticity, the dehumidifying plate is pressed tightly against the material. This allows the shape of the dehumidifying plate's absorbent surface to be changed according to the size and shape of the material, improving the dehumidifying plate's adaptability. It can also contact all sides of the material simultaneously, completing the moisture absorption treatment of all sides in one go, which is convenient and quick.

[0017] 4. Using a fan as a power source, the connection between the insert plate and the socket can be controlled, allowing the material plate to move horizontally with the insert plate. It can also be used to control the synchronous contraction or expansion of the dehumidification plate, making it easy for the dehumidification plate to adapt to materials of different shapes and sizes, fully contacting the sides of the materials and completing the moisture absorption work.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] Example 1: As Figure 1 - Figure 7As shown, an embodiment of the present invention provides a corrosion resistance testing device based on a corrosion foil, comprising: an outer box 12 connected to a housing 11; a plurality of channels 15 extending through one side of the housing 11, the channels 15 communicating with the outer box 12; and a material changing device 3 placed in each channel 15. The material changing device 3 is configured to move horizontally and enter and exit the housing 11. The material changing device 3 includes: a guide tube 31, the side of which is connected to the inner wall of the channel 15. A sealing groove 62 is provided through the top of the 1, and the sealing groove 62 is connected to the sealing plate 14. An outer guide rail 34 is connected to the inner wall of the guide tube 31. A material placement plate 33 is placed inside the guide tube 31. The middle of both sides of the material placement plate 33 near the box 11 is connected to a slide cylinder 39 through a rod 38. The slide cylinder 39 is slidably connected to the outer guide rail 34. A rotating plate 32 is connected to the other end of the guide tube 31. The rotating plate 32 is adapted to the slide cylinder 39. The material placement plate 33 is connected to a plug 36 through a socket 35.

[0035] The top of the housing 11 has a top groove 17, the bottom of which is connected to the top of the sealing groove 62. A first hydraulic cylinder 13 is installed above the housing 11. The telescopic end of the first hydraulic cylinder 13 is connected to the sealing plate 14. The bottom end of the sealing plate 14 passes through the top groove 17 and is inserted into the sealing groove 62. The sealing plate 14 is used to move vertically under the drive of the telescopic end of the first hydraulic cylinder and control the opening and closing of the sealing groove 62. A stepper motor 21 and a fan 24 are installed inside the outer box 12. The fixed end of the stepper motor 21 is connected to the top wall of the outer box 12. The rotating end of the stepper motor 21 is threadedly connected to a nut 23 through a lead screw 22. The side of the nut 23 is connected to the material changing device 3. The air outlet of the fan 24 is connected to the material changing device 3 through a first pipe 25. The air outlet of the fan 24 is connected to the adaptive cleaning device 4 through a second pipe 26.

[0036] One end of the guide tube 31 is connected to the inner wall of the channel 15, and the other end of the guide tube 31 passes through the channel 15 and extends into the outer box 12. A vertical hole 61 is formed in the middle of the upper surface of the guide tube 31 located in the outer box 12. First sliding grooves 63 are formed on the inner walls of both sides of the guide tube 31. An outer guide rail 34 is installed on the outside of the first sliding groove 63. A second sliding groove 64 is formed on one side of the outer guide rail 34 and the second sliding groove 64 is connected to the first sliding groove 63. One end of the first slide 63 is connected to the rotating plate 32, and the other end of the first slide 63 is connected to the inner guide rail 16. The first slide 63 and the second slide 64 are both slidably connected to the slide cylinder 39. The material placement plate 33 is a V-shaped plate. The end of the material placement plate 33 away from the box 11 is connected to the socket 35 through the pressure sealing plate 18. The top of the socket 35 is provided with a socket hole 65. The bottom end of the insert 36 is inserted into the socket hole 65. The width of the pressure sealing plate 18 is greater than the width of the sealing groove 62.

[0037] The insert 36 includes: an insert plate 361, which is inserted into the insertion hole 65. The top of the insert plate 361 is connected to a moving rod 363 via a connecting plate 362. The top of the moving rod 363 is connected to a windward plate 364. The center of the top of the windward plate 364 is connected to the top wall of the air duct 366 via a spring. The windward plate 364 is slidably connected to the inner wall of the air duct 366. A solenoid valve 367 is connected to the side of the top of the air duct 366. The solenoid valve 367 is connected to the fan 24 via a first pipe 25. The windward plate 364 is a bowl-shaped plate with its opening facing upward. The top of the air duct 366 is connected to the side of the nut 23 via a side plate 37.

[0038] In use, several material changing devices 3 are numbered. Material is placed on the material placement plate 33, and the number of the material changing device 3 on which the material placement plate 33 is located is determined. The solenoid valve 367 of the material changing device 3 that releases the material is then activated. For example, if there are three material changing devices 3, numbered 1, 2, and 3, and material is placed on material changing devices 1 and 2, then only material changing devices 1 and 2 need to be controlled to enter and exit the housing 11, and only the solenoid valves 367 of material changing devices 1 and 2 need to be opened. The air outlet of the blower 24 enters the air duct 366 through the first pipe 25. The pressure distribution inside the air duct 366 increases, and the wind-facing plate 364, along with the moving rod 363, connecting plate 362, and insert plate 361, moves downward. The first spring 365 is stretched, and the insert plate 361 is inserted into the socket 35. At this time, the insert 36 and the material placement plate 33 are connected as a whole. Start the first hydraulic cylinder 13. The telescopic end of the first hydraulic cylinder 13 moves the sealing plate 14 upward, and the sealing plate 14 no longer seals the channel 15. Start the bidirectional motor 41. The lead screw 22 rotates, and the nut 23 moves the side plate 37, the air duct 366, the wind-facing plate 364, the moving rod 363, the connecting plate 362, the insert plate 361, the socket 35, the material placement plate 33, and the material towards the box 11. The material placement plate 33 passes through the channel 15 and enters the box 11. The slide cylinder 39 slides along the outer guide rail 34 to the inner guide rail 16. Finally, the slide cylinder 39 slides to one end of the inner guide rail 16. At this time, the pressure sealing plate 18 is located directly below the sealing groove 62. The sealing plate 14 immediately moves downward. The bottom end of the sealing plate 14 passes through the top groove 17 and the sealing groove 62 and abuts against the top of the pressure sealing plate 18. The sealing plate 14 seals the channel 15.

[0039] When it is necessary to add new materials, detect different orientations of materials, or remove or replace materials, there is no need to open the top cover of the box 11 for handling. Instead, the position of the material plate 33 inside the box 11 is determined, the corresponding channel 15 of the material plate 33 is opened, and the material plate is quickly removed. When the channel 15 is opened, the bidirectional motor 41 reverses, and the nut 23 moves the side plate 37, the air duct 366, and the material plate 33 toward the outer box 12 in sequence. The slide cylinder 39 slides along the inner guide rail 16 to the outer guide rail 34, and the material plate 33 moves from inside the box 11 to the outer box 12. The sealing plate 14 moves down and seals the channel 15, reducing the time that the box 11 is in contact with the outside world and reducing the humidity loss and temperature changes caused by material handling. As the slide cylinder 39 slides, one end of the material placement plate 33 continuously extends out from one end of the guide tube 31. When the slide cylinder 39 slides along the outer guide rail 34 into the rotating plate 32, the material placement plate 33 extends out from one end of the guide tube 31 and is located inside the outer box 12.

[0040] In salt spray treatment of materials, it is generally not permitted to remove materials midway to ensure the stability of the test environment and avoid distortion of the material state. However, different types of materials require different salt spray treatment times, and materials need to be removed when they reach the designated salt spray treatment time. This makes it inconvenient to treat materials with different salt spray treatment times simultaneously, requiring batch treatment of materials with different treatment times. When there are many types of materials, this prolongs the total salt spray treatment time and reduces work efficiency. By constructing channel 15 and its compatible sealing components and material changing device 3, the treated materials can be replaced selectively. This allows materials with different salt spray treatment times to be treated in the same batch, and materials can be removed after the designated salt spray treatment time, minimizing the impact on other materials still undergoing salt spray treatment. This approach is highly adaptable. Furthermore, when surface salt spray treatment is required, the material can be quickly removed and channel 15 sealed. The small cross-section of channel 15 and its short opening time further reduce the impact of channel 15 opening.

[0041] Example 2: As Figure 1 - Figure 10As shown, an embodiment of the present invention provides a corrosion resistance testing device based on corrosion foil. Each material changing device 3 has a lower rotating baffle 52 located below one end. An adaptive cleaning device 4 is located on the side of each lower rotating baffle 52 away from the housing 11. The adaptive cleaning device 4 is used to absorb liquid from the surface of the material after salt spray treatment. The adaptive cleaning device 4 includes: a bidirectional motor 41, the fixed end of which is connected to the bottom wall of the outer housing 12; a rotating end of which is connected to a support plate 42; and an air box 43 located above the support plate 42. The air box 43 passes through a first plate. Connected to the inner wall of the outer box 12, the air box 43 is connected to several cylinders 45. The inner wall of each cylinder 45 near the air box 43 is connected to a wind cover 47 by a second spring 46. The wind cover 47 is slidably connected to the inner wall of the cylinder 45. The wind cover 47 is connected to a moving plate 48 by a push rod 71. The inner side of each moving plate 48 is connected to a dehumidifying plate 49. A flat plate 72 is set above each moving plate 48. The top of the inner side of each flat plate 72 is connected to a guide plate 44. The guide plate 44 is connected to the inner wall of the outer box 12 by a second plate. The top of the air box 43 is connected to the fan 24 by a second pipe 26.

[0042] The guide plate 44 is an arc plate, and the inner diameter of the guide plate 44 gradually narrows in the vertical direction. The inner diameter of the top of the guide plate 44 is larger than the inner diameter of the bottom of the guide plate 44. The inner diameter of the bottom of the guide plate 44 is equal to the inner diameter of the plate 72. The diameter of the plate 72 is larger than the inner diameter of the plate 72. The inner side of the dehumidification plate 49 is made of sponge material. The dehumidification plate 49 is used to gather and wrap the material under the action of thrust.

[0043] After the material changing device 3 moves to the box 11, when the slide cylinder 39 moves to the end of the inner guide rail 16 away from the outer box 12, the pressure sealing plate 18 is located directly below the sealing groove 62. The bottom end of the sealing plate 14 passes through the top groove 17 and the sealing groove 62 and is pressed against the top of the pressure sealing plate 18, and the channel 15 is sealed. When the material changing device 3 needs to move into the outer box 12, the material placing plate 33 moves along the direction of the first slide groove 63. When the slide cylinder 39 abuts against the rotating plate 32, one end of the material placing plate 33 is placed on the lower rotating baffle 52. The rotation angle of the material placing plate 33 is adjusted by controlling the height of the lower rotating baffle 52.

[0044] A corrosion resistance testing method for corrosion-resistant foil includes a corrosion resistance testing device based on the corrosion-resistant foil. A channel 15 is opened in the housing 11, allowing materials to enter and exit the housing 11 through the channel 15. A sealing plate 14 seals the channel 15, controlling the connection or isolation between the housing 11 and the outside world. A fan 24 is turned on, and a solenoid valve 367 is opened, increasing the pressure distribution inside the air duct 366. The windward plate 364 moves the insert plate 361 downwards, causing the insert plate 361 to engage with the socket 35. A lead screw 22 rotates, and a nut 23 moves the side plate 37, air duct 366, moving rod 363, insert plate 361, socket 35, and material placement plate 33 towards the housing 11. The material placement plate 33 carries the material through the channel 15 and into the housing 11. The insert plate 361 separates from the socket 35, and the insert plate 361 does not obstruct the movement of the sealing plate 14. The sealing plate 14 seals the channel 15. After some or all of the material has completed salt spray treatment, the corresponding electric fan 24 is turned on. The solenoid valve 367, the slide plate 361, and the socket 35 are connected. The bidirectional motor 41 reverses, and the slide plate 361 drives the material placement plate 33 to move towards the outer box 12. The slide cylinder 39 at one end of the material placement plate 33 moves from the inner guide rail 16 to the outer guide rail 34. After the material placement plate 33 is removed from the box 11, the sealing plate 14 immediately moves down and seals the channel 15. The slide cylinder 39 abuts against the rotating plate 32, and the material placement plate 33 extends completely from one end of the guide tube 31, thereby completing the material replacement or On the other side, one end of the material placement plate 33 is placed on the lower rotating baffle 52. As the lower rotating baffle 52 descends, the rod 38 and the slide cylinder 39 rotate relative to each other. One end of the material placement plate 33 moves down and tilts. The material slides down into the adaptive cleaning device 4. The air pressure inside the cylinder 45 increases. The air cover 47 moves along the axis of the air box 43 with the push rod 71, the moving plate 48, and the dehumidifying plate 49. The dehumidifying plate 49 squeezes the material and wraps it, absorbing the liquid on the surface of the material.

[0045] In use, the material placement plate 33 is completely pulled out from one end of the guide tube 31 and is located in the outer box 12. At this time, the end of the material placement plate 33 away from the box body 11 is placed on the lower rotating baffle 52. The lower rotating baffle 52 moves down with the extension end of the second hydraulic cylinder 51. The rotating plate 32 is adapted to the slide cylinder 39, and the rod 38 rotates relative to the slide cylinder 39. One end of the material placement plate 33 rotates downward, and the tilt angle of the material placement plate 33 increases. The material slides down the upper part of the material placement plate 33 onto the guide plate 44. The guide plate 44 and the support plate 42 are both elastic plates, and the height difference between the bottom end of the guide plate 44 and the material placement plate 33 is small, so the impact force of the falling material is small. The inner diameter of the guide plate 44 gradually shrinks in the vertical direction. Several guide plates 44 form a neck-shaped cylinder, and the material slides down the guide plate 44 onto the placement plate.

[0046] When the second pipe 26 is opened, air enters the air box 43 and the cylinder 45 sequentially through the second pipe 26. The air pressure inside the cylinder 45 increases. The air cover 47 moves sequentially along the longitudinal axis of the air box 43, carrying the push rod 71, the moving plate 48, and the dehumidifying plate 49. Several dehumidifying plates 49, which are equidistantly distributed along the circumference, tighten inward. As the dehumidifying plates 49 gradually approach each other, they compress the material. The inner side of the dehumidifying plate 49 is made of soft sponge or highly elastic absorbent material. The dehumidifying plate 49 wraps the material inside. The dehumidifying plate 49 continues to compress, and all contact surfaces of the dehumidifying plate 49 with the material are pressed and contacted. The dehumidifying plate 49 completely absorbs the liquid on the surface of the material.

[0047] The material moves in and out of the box 11 with the material placement plate 33. The two ends of the movement path serve as limit points to facilitate the sealing and rotation of the material placement plate 33. After rotation, the material placement plate 33 is adapted to the self-adaptive cleaning device 4 to complete the material removal and cleaning in one go, which facilitates the replacement of materials.

[0048] Materials come in various sizes and shapes, making manual wiping time-consuming and laborious; evaporation with heat is time-consuming and inefficient; and clamping and spin-drying results in complex structures and difficult maintenance. This device utilizes the material's own gravity to cause it to fall and tumble, allowing liquid in the material's depressions to flow out as much as possible. Then, through elasticity and plasticity, the dehumidifying plate 49 is pressed tightly against the material. This allows the shape of the dehumidifying plate 49's absorbent surface to be changed according to the size and shape of the material, improving its adaptability. It can also simultaneously contact all sides of the material, completing the dehumidification treatment of all sides in one go, which is convenient and fast.
