Description

Technical Field

[0001] This invention relates to the field of aluminum alloy processing technology, and in particular to an aluminum alloy stamping and stretching device. Background Technology

[0002] The aluminum alloy stamping and stretching device is a composite process equipment specifically designed for processing aluminum alloy sheets. It combines roll forming structure with stamping and stretching process, applying continuous pressure to the aluminum alloy sheet through precisely arranged rollers to achieve plastic deformation and stretching of the material.

[0003] However, in practical applications, some problems remain unresolved. The following are some common problems with aluminum alloy stamping and stretching devices: During the stamping and stretching process, rollers are needed to heat the aluminum alloy. In most cases, channels are set inside the rollers to circulate the heat transfer fluid to achieve the heating function. However, during device maintenance and cleaning of oil stains on the roller surface, the residual heat transfer fluid in the rollers causes slow cooling. Slight contact can easily cause burns. Furthermore, the tools used to clean oil stains on the roller surface are in fixed positions when the rollers are running. During shutdown maintenance or deep cleaning, there are areas that are difficult to clean. Even if the tools are removed for cleaning, the process is cumbersome and inconvenient.

Detailed Implementation

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1, referring to Figures 1 to 7 This is the first embodiment of the present invention. This embodiment provides an aluminum alloy stamping and stretching device. The aluminum alloy stamping and stretching device includes a platform 1, an stretching mechanism 2, and a cleaning and tensioning mechanism 3. With the cooperation of the stretching mechanism 2, the cleaning and tensioning mechanism 3 can drain the residual heat-conducting liquid in the roller during device maintenance and cleaning of oil stains on the roller surface, and assist in cooling and heat dissipation. During shutdown maintenance or deep cleaning, the cleaning tools are far away from the roller, and there is a certain distance between them, which makes it convenient for operators to deeply clean the entire surface of the roller and the stains scraped off the cleaning tools.

[0039] Specifically, the extension mechanism 2 is fixed to the top of the platform 1, including a frame 21 fixed to the top of the platform 1. A lower roller 22 rotates on the frame 21. A hydraulic cylinder 23 is fixed to the top of the frame 21. A moving block 24 slides on the frame 21. The output end of the hydraulic cylinder 23 passes through the frame 21 and is fixed to the top of the moving block 24. An upper roller 25 rotates on the moving block 24. The lower roller 22 is rotatably connected to the frame 21 through a bearing. The moving block 24 is slidably engaged on the frame 21. The upper roller 25 is rotatably connected to the moving block 24 through a bearing. A motor 26 is fixed on the moving block 24 and is located at one end of the upper roller 25 and the lower roller 22. A switching component 27 is installed at one end of the lower roller 22 and is located on the frame 21 and the moving block 24. A connecting piece 28 is installed on the upper roller 25 and the lower roller 22. An inlet pipe 29 is connected to the switching component 27. An outlet pipe 210 is connected to one end of the lower roller 22.

[0040] The lifting and lowering of the moving block 24 is controlled by the extension and retraction of the hydraulic cylinder 23, thereby adjusting the distance between the two sets of upper rollers 25 and lower rollers 22. Under the action of their rotation, the aluminum alloy passing between them is extruded and extended step by step. The motor 26 is a geared motor equipped with a reducer and is installed on the upper roller 25 and lower roller 22. This is existing technology. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. It can drive the rotation of the corresponding upper roller 25 and lower roller 22, and extrudes and extends the aluminum alloy while conveying it.

[0041] The two sets of upper rollers 25 and lower rollers 22 are connected by the connecting piece 28, so that the heat transfer liquid required for heating passes sequentially through the front upper roller 25, lower roller 22, and rear upper roller 25 and lower roller 22, and then is discharged from the liquid outlet pipe 210. The upper rollers 25 and lower rollers 22 are heated by heat transfer, thereby heating the aluminum alloy that has been extruded and stretched between the upper rollers 25 and lower rollers 22, ensuring the extrusion and stretching temperature, and avoiding the aluminum alloy temperature being too low, which would affect the extrusion and stretching effect and quality.

[0042] By setting the switching component 27, during the process of adjusting the processing distance by driving the moving block 24 down with the hydraulic cylinder 23 to move the upper roller 25 down, the switching component 27 switches to keep the inlet pipe 29 connected to the upper roller 25, the lower roller 22 and the connecting piece 28, so that the heat transfer fluid circulates through the channel and continuously heats the upper roller 25 and the lower roller 22. When the processing is completed and the upper roller 25, the lower roller 22 and the cleaning piece 36 need to be deeply cleaned, the hydraulic cylinder 23 retracts and drives the moving block 24 and the upper roller 25 to move up. The switching component 27 switches to keep the dust suction piece 33 connected to the upper roller 25, the lower roller 22 and the connecting piece 28, closes the inlet pipe 29, and forces the gas into the connected channel.

[0043] The heat-conducting liquid inside the upper roller 25, lower roller 22, and connecting piece 28 is quickly emptied to prevent it from remaining inside. Otherwise, the temperature of the upper roller 25 and lower roller 22 will drop slowly, resulting in high temperatures during maintenance and cleaning. Careless contact could cause burns, and prolonged presence could easily lead to dirt buildup. At the same time, the continuous introduction and discharge of gas can quickly cool the upper roller 25 and lower roller 22, playing an auxiliary cooling role. This allows maintenance personnel to carry out maintenance or cleaning work in a shorter time, improving efficiency and safety. One end of the liquid outlet pipe 210 is rotatably connected to the lower roller 22 on the rear side through a sealed bearing. This ensures that the lower roller 22 rotates while maintaining communication with the liquid outlet pipe 210, preventing liquid leakage and not affecting the rotation of the lower roller 22.

[0044] Specifically, the cleaning tensioning mechanism 3 is installed on the platform 1 and the extension mechanism 2, including a support member 31 fixed to the top of the platform 1, an air suction plate 32 fixed on the support member 31, a dust suction member 33 installed on one side of the platform 1 and communicating with the air suction plate 32 and cooperating with the switching component 27, a limit member 34 installed on the air suction plate 32, and a transmission member 35 installed on the frame 21, the moving block 24, the platform 1 and the support member 31, a cleaning member 36 fixed on the transmission member 35 and cooperating with the upper roller 25 and the lower roller 22.

[0045] The support member 31 provides a position for the installation of the suction plate 32, fixes and supports one suction plate 32, and applies force to the other suction plate 32, thereby pressing the aluminum alloy passing between the two suction plates 32. This ensures that the aluminum alloy is kept taut between the upper roller 25 and the lower roller 22 and the suction plate 32, preventing it from loosening when extruding and stretching between the upper roller 25 and the lower roller 22, thus improving the extrusion and stretching effect and quality. Furthermore, the overall "<" shape design of the suction plate 32, due to the close contact between the upper and lower suction plates 32 and the surface to be extruded and stretched, can scrape and guide dust and impurities on the surface of the conveyed aluminum alloy, allowing the retained dust and impurities to be discharged to both sides, reducing the impact of dust and impurities on the quality of extrusion and stretching of the aluminum alloy by the upper roller 25 and the lower roller 22.

[0046] With the suction component 33 in place, when the suction plate 32 traps dust and impurities on the aluminum alloy, the suction force can draw in the dust and impurities for collection, and then discharge the gas. At this time, the suction component 33 is not connected to the switching component 27, and the gas will not enter the upper roller 25 and the lower roller 22. After processing is completed, the upper roller 25 moves up and resets to the starting position. At this time, the switching component 27 switches to connect with the suction component 33, closes the liquid inlet pipe 29, and closes the air outlet of the connecting part 28, so that the gas discharged by the suction component 33 can enter the connected channel, quickly drain the heat-conducting liquid in the upper roller 25, the lower roller 22 and the connecting part 28, and assist in cooling and heat dissipation, so that it can be quickly cooled to the temperature range that can be inspected and deeply cleaned, thereby improving the inspection efficiency and safety.

[0047] By setting the limiting component 34, when the two suction plates 32 act on the aluminum alloy, they can limit and center the conveyed aluminum alloy, preventing it from shifting laterally over a large range during conveying, thus ensuring the quality of extrusion and stretching. Furthermore, the limiting component is self-adaptive and requires no manual adjustment. The limiting of the conveyed aluminum alloy is completed during the device's start-up and adjustment process, and the limiting of the aluminum alloy is released during the control of the upper roller 25's upward movement when the device stops working. This results in a high degree of automation. The upper suction plate 32 in the pair of suction plates 32 can press the conveyed aluminum alloy during the device's start-up and adjustment process, and can move upward and detach from the aluminum alloy surface during the control of the upper roller 25's upward movement when the device stops working, thus releasing the pressing.

[0048] By configuring the transmission component 35, during the adjustment of the device when it is started, the upper roller 25 and the moving block 24 move downwards, which allows the corresponding cleaning component 36 to move closer to the upper roller 25 and the lower roller 22 and make contact with them. During the operation of the device, as the upper roller 25 and the lower roller 22 rotate, the cleaning component 36 can scrape off the dust, impurities and oil stains on their surfaces, preventing the upper roller 25 and the lower roller 22 from slipping when extruding and stretching the aluminum alloy, and reducing the impact of surface dust and impurities on the quality of extruding and stretching the aluminum alloy by the upper roller 25 and the lower roller 22. When the device stops working and the upper roller 25 and the moving block 24 move upwards to reset, the cleaning component 36 moves away from the upper roller 25 and the lower roller 22, with a certain distance between them, which facilitates the operator to perform deep cleaning of the entire surface of the upper roller 25 and the lower roller 22, as well as the cleaning component 36 and the stains scraped off on it, making it convenient for maintenance and deep cleaning operations.

[0049] Example 2, refer to Figures 3 to 16 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0050] Specifically, the connecting component 28 includes a bent tube 281 connected to one end of the upper roller 25, a telescopic tube 282 connecting the two bent tubes 281, the bent tube 281 being fixed to the moving block 24 by a support rod, a bent tube 283 connecting one end of the upper roller 25 and the lower roller 22, a telescopic tube 284 connecting the bent tube 283 at one end of the upper roller 25 and the lower roller 22, and the bent tube 283 being fixed to the motor 26 by a support rod.

[0051] The first bend 281 is rotatably connected to the upper roller 25 via a sealed bearing, and the second bend 283 is rotatably connected to both the upper roller 25 and the lower roller 22 via a sealed bearing. This connection method ensures that while the first bend 281 is connected to the upper roller 25, and the second bend 283 is connected to both the upper roller 25 and the lower roller 22, it does not affect the rotation of the upper roller 25 and the lower roller 22 driven by the motor 26. This does not obstruct the normal flow and circulation of the heat transfer fluid. The first telescopic tube 282 ensures that the movement and connection between the two upper rollers 25 are not affected when they are raised or lowered at different times. The second telescopic tube 284 ensures that the upper roller 25 above the lower roller 22 is not obstructed during the raising and lowering process, and does not affect the connection between them.

[0052] The switching assembly 27 includes a three-way valve housing 271 connected to one end of the lower roller 22. One end of the three-way valve housing 271 is rotatably connected to the lower roller 22 via a sealed bearing. This arrangement ensures that the upper roller 25 remains connected to one end of the three-way valve housing 271 while rotating. The three-way valve housing 271 is fixed to the frame 21 by a support rod. A valve block 272 rotates inside the three-way valve housing 271. A seal is provided between the valve block 272 and the three-way valve housing 271 to prevent liquid from leaking from the gaps. A valve stem 273 and a short rod 278 rotate on the three-way valve housing 271, both of which are fixed to the valve block 272. The valve stem 273 is rotatably connected to the cross plate 274 via a bearing. A ball bearing 276 rotates at one end of the cross rod 275.

[0053] A horizontal plate 274 is fixed on one side of the frame 21. The upper end of the valve stem 273 rotates at one end of the horizontal plate 274. A horizontal bar 275 is fixed on one side of the moving block 24. A ball bearing 276 is embedded at one end of the horizontal bar 275. A guide groove 277 is opened on the surface of the valve stem 273, and the ball bearing 276 slides in it. A baffle 279 is fixed at the lower end of the short rod 278, and it cooperates with the dust collection component 33.

[0054] The guide groove 277 is divided into three parts. The first and third parts prevent the valve stem 273 from rotating when the ball 276 moves within it, thus preventing the valve block 272 from rotating within the three-way valve housing 271. The second part allows the valve stem 273 to rotate when the ball 276 moves within it. When the moving block 24 and the upper roller 25 move down from their initial positions, the crossbar 275 drives the ball 276 to move down. The ball 276 moves from the first part of the guide groove 277 through the second part into the third part, causing the valve stem 273 and the valve block 272 to rotate 90 degrees. The valve block 272 keeps the liquid inlet pipe 29 connected to the upper roller 25, the lower roller 22, and the connecting piece 28, circulating the heat transfer liquid through the channel and continuously heating the upper roller 25 and the lower roller 22.

[0055] When the processing is completed and the upper roller 25, lower roller 22 and cleaning component 36 need to be deeply cleaned, the hydraulic cylinder 23 retracts, driving the moving block 24 and upper roller 25 to move upward. The valve block 272 switches to keep the dust suction component 33 connected to the upper roller 25, lower roller 22 and connecting component 28, and closes the liquid inlet pipe 29, so that the gas is forced into the connected channel, and the heat transfer liquid in the upper roller 25, lower roller 22 and connecting component 28 is quickly emptied to prevent it from remaining inside.

[0056] By setting baffle 279, when the switching component 27 is switched to keep the liquid inlet pipe 29 connected to the upper roller 25, lower roller 22 and connecting member 28, baffle 279 will not block the exhaust port of the dust collection component 33, allowing it to exhaust normally. When the switching component 27 is switched to keep the dust collection component 33 connected to the upper roller 25, lower roller 22 and connecting member 28, baffle 279 can block the exhaust port connected to the atmosphere, allowing the exhaust gas to be discharged into the connected channel, and quickly emptying the heat transfer liquid in the upper roller 25, lower roller 22 and connecting member 28.

[0057] The support member 31 includes a limiting rod 311 fixed to the top of the platform 1. A fixing block 312 is fixed to the surface of the limiting rod 311. The fixing block 312 is fixedly sleeved on the surface of the limiting rod 311. A movable block 313 is sleeved on the surface of the limiting rod 311 and cooperates with the transmission member 35. The movable block 313 is slidably sleeved on the surface of the limiting rod 311. Through the setting of the movable block 313, the transmission member 35 can make the structure on the transmission member 35 contact the moving block 24 under the action of the moving block 24. As the moving block 24 moves upward, it moves upward along with the upper suction plate 32, increasing the distance between the two suction plates 32. This makes it easier to pass the aluminum alloy that needs to be stamped and stretched through the two suction plates 32 and between the upper roller 25 and the lower roller 22. As the moving block 24 gradually moves downward, the transmission member 35 releases its action on the movable block 313.

[0058] The suction plate 32 is fixed to the surface of the fixed block 312 and the movable block 313 respectively. The upper surface of the limiting rod 311 is fitted with a spring 314, and its two ends are fixed to the upper end of the limiting rod 311 and the top of the movable block 313 respectively. Through the setting of the spring 314, when the movable block 313 drives the suction plate 32 on it to move upward, it is continuously compressed, providing a force for the movable block 313 and the suction plate 32 on it to reset. After the upper suction plate 32 comes into contact with the aluminum alloy, it provides a holding force, so that the upper and lower suction plates 32 are in full contact with the aluminum alloy, improving the cleaning effect.

[0059] The dust collection component 33 includes a dust collection box 331 fixed to one side of the platform 1 and an air pump 332. The suction plate 32 is a hollow plate with air holes. A removable filter screen is installed inside the dust collection box 331, which can filter, intercept and collect the dust and impurities sucked in. All of these are existing technologies. The working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. The input end of the air pump 332 is connected to the top of the dust collection box 331. A connecting pipe 333 connects the suction plate 32 and the dust collection box 331. The output end of the air pump 332 is connected to a three-way pipe 334. One end of the three-way pipe 334 is connected to one end of the three-way valve housing 271, and the other end of the three-way pipe 334 is matched with a baffle 279. A telescopic pipe 335 connects the two suction plates 32.

[0060] With the dust collector 331 in place, the air pump 332 can draw in gas through the suction plate 32, thereby carrying in the dust and impurities trapped near the suction plate 32. The gas then enters the dust collector 331 through the connecting pipe 333 for filtration and is discharged from one end of the three-way pipe 334, ensuring that the discharged gas is clean. This prevents impurities from adhering to the upper roller 25 and lower roller 22 when they are subsequently switched in.

[0061] Example 3, referring to Figures 3 to 11 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0062] Specifically, rollers 341 are fixed at both ends of the upper suction plate 32, and square rods 342 slide at both ends of the lower suction plate 32. The square rods 342 pass through the suction plate 32 and are slidably connected to it. A roller 343 rotates at one end of the square rod 342, and a drive plate 344 is fixed at the other end. The roller 343 is rotatably connected to the square rod 342 through a bearing. The drive plate 344 cooperates with the rollers 341. A spring 345 is sleeved on the surface of the square rod 342 near the drive plate 344, and its two ends are fixed to the surface of the suction plate 32 and the surface of the drive plate 344, respectively.

[0063] With the drive plate 344 in place, when the roller 341 moves upward with the upper suction plate 32, it can be squeezed, causing it to move and drive the square rod 342 and the roller 343 to move. The spring 345 is stretched, causing the roller 343 to detach from the aluminum alloy surface and release the elastic limit on both sides. No additional manual operation is required. It can be released during the upward movement of the moving block 24 and the upper roller 25.

[0064] With the setting of spring 245, when the upper roller 25 and the moving block 24 move down, the connecting plate 357 on it moves down and gradually disengages from the movable block 313 under the action of the transmission component 35. Under the action of the spring 1 314, the movable block 313 and the suction plate 32 on it move down, thereby driving the roller 341 to move down and release the limit on the drive plate 344. Under the action of the spring 2 345, the drive plate 344, the square rod 342 and the roller 343 move back, so that the surface of the roller 343 contacts the side of the aluminum alloy. Under the action of the elastic force of spring 2 345, the roller 343 self-adaptively limits the aluminum alloy.

[0065] The transmission component 35 includes a guide rod 351 fixed to the movable block 24, a guide rod 352 fixed to one side of the frame 21, a square plate 353 fixed to the surface of the limiting rod 311, and an L-shaped plate 354 fixed to the top of the platform 1. Sliding sleeves 355 are fitted on the surfaces of the square plate 353 and the L-shaped plate 354 respectively. The sliding sleeves 355 slide on the square plate 353 and the L-shaped plate 354 respectively. A guide frame 356 is fixed to the top of the sliding sleeve 355. The guide frame 356 is divided into three parts. The first and second parts are guide posts 358. When they move, the guide frame 356 and the sliding sleeve 355 will not move. The second part is guide posts 358. When they move, the guide frame 356 and the sliding sleeve 355 can move, thereby moving the L-shaped block 3511, the movable sleeve 359, and the movable sleeve 3510. The movable sleeve 359 is slidably fitted on the surface of the guide frame 356.

[0066] A connecting plate 357 is fixed on the movable block 24, and a guide post 358 is fixed at one end of the plate. One end of the guide post 358 slides inside the guide frame 356. A movable sleeve 359 is fitted on the surface of the first guide rod 351 and is fitted on the surface of the guide frame 356. A movable sleeve 3510 is fitted on the surface of the second guide rod 352. An L-shaped block 3511 slides inside the movable sleeve 3510 and is fixed to the surface of the sliding sleeve 355. The connecting plate 357 cooperates with the movable block 313.

[0067] By setting the movable sleeve 359, when the movable block 24 moves up and down, it can drive the guide rod 351 to move up and down, thereby driving the movable sleeve 359 and the cleaning part 36 on it to move up and down, synchronously with the up and down movement of the upper roller 25. At the same time, when the movable block 24 moves up and down, it drives the connecting plate 357 and the guide post 358 on it to move within the guide frame 356. The movement of the guide frame 356 can drive the movable sleeve 359 to move laterally, so that the cleaning part 36 moves away from or closer to the upper roller 25. When the cleaning part 36 is close to the upper roller 25, it corresponds to the downward movement of the movable block 24. Conversely, when the cleaning part 36 is away from the upper roller 25, it corresponds to the downward movement of the movable block 24. This makes it convenient for the operator to perform deep cleaning of the entire surface of the upper roller 25 and the lower roller 22, as well as the cleaning part 36 and the stains scraped on it, after processing is completed. This facilitates maintenance and deep cleaning operations.

[0068] By setting the movable sleeve 3510, when the L-shaped block 3511 moves with the sliding sleeve 355, it can drive the cleaning part 36 below to move, and the cleaning part 36 at the upper roller 25 is in the same state, ensuring synchronization. The lower cleaning part 36 of the movable block 24 moves closer to the lower roller 22, and the upper cleaning part 36 of the movable block 24 moves away from the lower roller 22.

[0069] The cleaning component 36 includes a fixed plate 361 fixed to the surfaces of movable sleeve 1 359 and movable sleeve 2 3510. A movable bolt 362 slides on the fixed plate 361, and a scraper 363 is fixed to one end of the bolt. The movable bolt 362 passes through the fixed plate 361 and is slidably connected to it. The movable bolt 362 limits and guides the scraper 363. The scraper 363 cooperates with the upper roller 25 and the lower roller 22 respectively. A spring 364 is sleeved on one end of the movable bolt 362, and its two ends are respectively Fixed to the surfaces of the scraper 363 and the fixed plate 361, the cleaning component 36 moves with the moving sleeve 1 359 and the moving sleeve 2 3510, causing the scraper 363 to contact the upper roller 25 and the lower roller 22. As the moving sleeve 1 359 and the moving sleeve 2 3510 continue to move, the fixed plate 361 compresses the spring 364, making the scraper 363 in close contact with the upper roller 25 and the lower roller 22, with an interference fit, thus improving the cleaning effect.

[0070] Example 4, refer to Figures 1 to 13 This is the fourth embodiment of the present invention, which is based on the first three embodiments.

[0071] Specifically, the upper roller 25 includes a roller body 251 that rotates on the moving block 24. The roller body 251 has a cavity 252 and a spiral hole 253 respectively. The cavity 252 and the spiral hole 253 are connected. The upper roller 25 and the lower roller 22 have the same structure. By setting two cavities 252 on a roller body 251 and cooperating with the spiral hole 253, the heat transfer oil entering the roller body 251 is diverted and then collected and discharged. Under the effect of the spiral hole 253 extending the flow path, the heat transfer contact time of the heat transfer liquid through the roller body 251 is increased.

[0072] The transmission component 35 is fitted with a cover 4 and fixed to the surface of the frame 21. The cover 4 shields the corresponding internal structure, protecting the machinery and personnel. One side of the cover 4 is equipped with an openable door for easy maintenance and cleaning.

[0073] Both the first movable sleeve 359 and the second movable sleeve 3510 have a placement frame 37 fixed to their bottoms by a support rod. A collection cylinder 38 is placed inside the placement frame 37. The placement frame 37 facilitates the placement and positioning of the collection cylinder 38 and allows the collection cylinder 38 to be removed. The collection cylinder 38 facilitates the collection of dirt flowing down the scraper 363.

[0074] In use, the inlet pipe 29 and the outlet pipe 210 are connected to an external heating device through pipelines, and the heating device can be connected to the atmosphere. When the hydraulic cylinder 23 drives the moving block 24 to move down, the upper roller 25 moves down. During the process of adjusting the processing distance, the switching component 27 switches to keep the inlet pipe 29 connected to the upper roller 25, the lower roller 22 and the connecting piece 28, so that the heat transfer liquid circulates through the channel, thereby continuously heating the upper roller 25 and the lower roller 22.

[0075] Driven by the transmission component 35, as the upper roller 25 and the moving block 24 move downward, the corresponding cleaning component 36 can move closer to the upper roller 25 and the lower roller 22 and come into contact with them. During the operation of the device, as the upper roller 25 and the lower roller 22 rotate, the cleaning component 36 can scrape off the dust, impurities and oil stains on their surfaces. When the suction plate 32 intercepts the dust and impurities on the aluminum alloy, the operation of the dust suction component 33 can suck in the dust and impurities for collection and then discharge the gas. At this time, the dust suction component 33 is not connected to the switching component 27, and the gas will not enter the upper roller 25 and the lower roller 22.

[0076] After processing is completed, the upper roller 25 moves up and resets to the starting position. At this time, the switching component 27 switches to connect with the dust collection component 33, closes the liquid inlet pipe 29, and closes the air outlet of the connecting component 28, allowing the gas discharged by the dust collection component 33 to enter the connected channel and quickly drain the heat transfer liquid in the upper roller 25, lower roller 22, and connecting component 28. At the same time, under the drive of the transmission component 35, the cleaning component 36 is moved away from the upper roller 25 and lower roller 22, with a certain distance between them, which makes it convenient for operators to perform deep cleaning on the entire surface of the upper roller 25 and lower roller 22, as well as the cleaning component 36 and the stains scraped on it, facilitating maintenance and deep cleaning operations.

[0077] In summary, by cleaning the tensioning mechanism 3 in conjunction with the extension mechanism 2, the residual heat-conducting liquid inside the roller can be drained during equipment maintenance and oil stain removal on the roller surface, and cooling and heat dissipation can be assisted. Compared with the existing technology, it can quickly cool down to a safe temperature range, improve maintenance efficiency and safety. During shutdown maintenance or deep cleaning, the cleaning tools are kept away from the roller, with a certain distance between them, which makes it convenient for operators to deeply clean the entire surface of the roller and the stains scraped off the cleaning tools.
