Description

Technical Field

[0001] The invention relates to the field of aluminum mold cleaning, and in particular to a double-layer isolation type dynamic cleaning device and method for aluminum mold anodizing. Background Art

[0002] Before the anodizing process, residual impurities in the cleaning process will affect the quality of the oxide film. Traditional cleaning methods have limited effect on removing residual impurities on the surface of aluminum molds. It is difficult to completely remove stubborn pollutants attached to the surface, and it still cannot meet the requirements of thorough cleaning in terms of completely removing residual impurities on the surface of aluminum molds. This may lead to problems such as uneven thickness, decreased bonding strength or defects of the oxide film on the surface of the aluminum mold during the subsequent anodizing process, thereby weakening the performance of the final product.

[0003] The aluminum template cleaning device disclosed in the Chinese authorization announcement number CN111545517B comprises a horizontal plate, a plurality of hollow shafts penetrating the horizontal plate, and a rotary mechanism for driving the hollow shafts to rotate circumferentially; one end of the hollow shaft is connected to a cleaning nozzle, and the other end is connected to a water source through a rotary joint; a U-shaped tube is connected to the hollow shaft, and cleaning nozzles are arranged at both pipe openings of the U-shaped tube; adjacent U-shaped tubes are vertically distributed, and the spray cleaning ranges of the cleaning nozzles on adjacent U-shaped tubes overlap; the rotary mechanism comprises a transmission shaft arranged on the horizontal plate, a driving part for driving the transmission shaft to rotate, and a driving part for driving each A transmission assembly in which a hollow shaft rotates synchronously with a transmission shaft; the driving part includes a driving motor connected to the transmission shaft; the hollow shafts are arranged in a straight line at intervals along the length direction of the cross plate, and the transmission assembly includes a row of synchronous shafts arranged on the cross plate and parallel to the row of hollow shafts; each of the synchronous shafts is provided with a synchronous gear, and the hollow shafts and the transmission shaft are provided with a rotating gear; the synchronous gear on the synchronous shaft close to the transmission shaft is meshed with the rotating gear on the adjacent hollow shaft and the rotating gear on the transmission shaft at the same time, and the synchronous gears on the remaining synchronous shafts are meshed with the rotating gears on two adjacent hollow shafts at the same time.

[0004] According to the above patent, the aluminum template is not prone to lateral deviation by pressing the pressing roller, so that the aluminum template is always within the flushing and cleaning range of the cleaning nozzle, and it is not easy to produce cleaning dead corners. However, the above patent only has a single cleaning step, and it is difficult to completely remove pollutants on the surface of the aluminum template. Simply relying on a cleaning nozzle in a fixed position, the aluminum template can usually only be cleaned from one direction, and the impact cleaning force of the nozzle alone is limited. Before anodizing treatment, the aluminum template cannot be fully cleaned. Therefore, there is a need for a double-layer isolation dynamic cleaning device that can fully clean the aluminum template while maintaining its stability. Summary of the invention

[0005] In view of the problems existing in the prior art, a double-layer isolated dynamic cleaning device for anodizing of aluminum molds is provided. After the aluminum template is adjusted to a vertical state by rotating the support assembly, the aluminum template is clamped between the rubber strip and the rubber roller and the clamp is away from the aluminum template. The pressure roller in the flushing assembly uses a high-pressure nozzle to fully cover the front and back sides of the aluminum template for cleaning. At the same time, the flexible layer on the pressure roller stably clamps the aluminum template under a slight squeeze state to prevent shaking and effectively scrape off residues, thereby improving the all-round cleaning effect.

[0006] In order to solve the problems of the prior art, the present invention provides a double-layer isolation dynamic cleaning device for anodizing of aluminum molds, which is applied to aluminum templates and includes a cleaning bin body and a conveying mechanism arranged therein for horizontally conveying the aluminum template. An external isolation chamber for preliminary decontamination of the aluminum template and an internal dynamic cleaning chamber for full coverage flushing of the aluminum template are formed in the cleaning bin body. A dynamic cleaning mechanism is provided in the internal dynamic cleaning chamber. The dynamic cleaning mechanism includes a rotating support assembly capable of adjusting the angle of the aluminum template and a flushing assembly capable of cooperating therewith to simultaneously clean both sides of the aluminum template. When the rotating support assembly is in a working state, the aluminum template is driven in a vertical state so that both sides of the aluminum template are exposed to the outside to cooperate with the flushing assembly for flushing operations.

[0007] Preferably, the flushing assembly includes pressure rollers symmetrically arranged on both sides of the rotating support assembly, each of the pressure rollers is provided with a plurality of high-pressure nozzles at equal intervals along its axial direction, both of the pressure rollers are capable of moving along the vertical direction of the aluminum template, and both ends of each of the pressure rollers extend horizontally to the side area of ​​the aluminum template.

[0008] Preferably, each pressing roller is provided with a flexible layer capable of contacting the surface of the aluminum template. When the pressing roller moves up and down along the surface of the aluminum template, the flexible layer is in an extrusion state against the surface of the aluminum template, so that the aluminum template is stably clamped while attached dirt and residual liquid are scraped off.

[0009] Preferably, the flushing assembly also includes a rotating guide rail capable of driving the pressure rollers to gradually approach each other when the aluminum template is in a vertical state, each pressure roller is slidably arranged on one of the rotating guide rails, and a support for rotationally connecting the rotating guide rail is provided in the internal dynamic cleaning chamber, and the rotating guide rail is provided with a block that cooperates with the support to ensure that the rotating guide rail is parallel to the surface of the aluminum template.

[0010] Preferably, a sliding seat capable of driving the pressure roller to move along its length direction is provided on the rotating guide rail, and the pressure roller can rotate on the sliding seat toward the direction of the aluminum template to adjust the angle of the high-pressure nozzle.

[0011] Preferably, the rotating support assembly includes a rotating shaft and a plurality of clamps evenly distributed around the rotating shaft, wherein each clamp is provided near both ends of the rotating shaft, and each clamp can move along the axial direction of the rotating shaft to fully expose the surface of the aluminum template.

[0012] Preferably, a rubber strip for supporting the aluminum template is provided on the rotating shaft and between every two corresponding clamps, and a rubber roller is provided on the support which can face one of the rubber strips each time. When the aluminum template is rotated to a vertical state, the aluminum template is clamped between the rubber strip and the rubber roller.

[0013] Preferably, the clamp consists of two clamps, and a slide rail for each clamp is provided on the rotating shaft along its axial direction for sliding. The rotating shaft is also provided with a pusher that can drive the two clamps to move outward away from the aluminum template at the same time, and a reset connector is provided between each clamp and the rotating shaft.

[0014] Preferably, a pressure sensor is provided between the rubber roller and the support, and the pressure sensor is electrically connected to the pusher. When the rubber roller is squeezed by the aluminum template, the pressure sensor detects the pressure change, causing the pusher to push the clamp holding the aluminum template to be cleaned away from the aluminum template.

[0015] The present invention also provides a double-layer isolation type dynamic cleaning method for aluminum mold anodizing, comprising the following steps: S1. The aluminum template is sent into the external isolation chamber through the conveying mechanism, and the nozzle assembly is used for preliminary decontamination to remove large particles of impurities and some oil stains on the surface; S2. The aluminum template that has been preliminarily cleaned is transferred from the transfer assembly to the internal dynamic cleaning chamber, and is placed on the rotating support assembly and adjusted to a vertical state; S3. The pressure roller in the flushing assembly moves along the surface of the aluminum template, and the high-pressure nozzle fully covers both sides for deep cleaning, and the flexible layer simultaneously scrapes off the residue.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention achieves efficient, thorough and non-damaging cleaning of the aluminum template through the coordinated cooperation of the rotating support component and the flushing component. After the rotating support component adjusts the aluminum template to a vertical state, the pressure roller in the flushing component starts from the top, and uses a high-pressure nozzle to fully cover the front and back of the aluminum template for cleaning. In this process, the pressure roller moves slowly in the vertical direction, and the flexible layer maintains contact with the surface of the aluminum template under a slight squeeze state, which not only stably clamps the aluminum template to prevent shaking, but also effectively scrapes off residual liquid and difficult-to-dissolve pollutants; 2. The present invention realizes the precise and efficient cleaning effect of the pressure roller on the surface of the aluminum template through the coordinated work of the rotating guide rail, the linear drive and the angle adjustment drive. The water jet direction of the high-pressure nozzle is optimized to ensure that the cleaning liquid is fully covered without dead angles. As the pressure roller gradually approaches the aluminum template and cooperates with the support and the block, it ensures that the rotating guide rail always remains parallel to the vertical aluminum template, thereby avoiding the cleaning effect or surface damage caused by angle deviation; 3. The present invention realizes stable clamping of the aluminum template during the cleaning process through the coordinated cooperation of the rubber strip and the rubber roller. At the same time, the clamp is driven by the pusher to keep the clamp away from the aluminum template, ensuring that the high-pressure nozzle can perform all-round and efficient cleaning of the aluminum template. That is, as the rotating shaft rotates a fixed angle each time, the clamp drives the aluminum template into the rubber strip and the rubber roller and the pusher moves the clamp away from the aluminum template, making it completely exposed between the pressure rollers, ensuring that both sides are fully washed.

DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] See also Figure 1-Figure 7 As shown, a double-layer isolation dynamic cleaning device for anodizing of aluminum molds is applied to an aluminum template 1, comprising a cleaning bin 2 and a conveying mechanism 3 arranged therein for horizontally conveying the aluminum template 1, wherein the cleaning bin 2 is provided with an external isolation chamber 21 for preliminary decontamination of the aluminum template 1 and an internal dynamic cleaning chamber 22 for full coverage flushing of the aluminum template 1, wherein a dynamic cleaning mechanism is arranged in the internal dynamic cleaning chamber 22, and the dynamic cleaning mechanism comprises a rotating support assembly 4 capable of adjusting the angle of the aluminum template 1 and a flushing assembly 5 capable of cooperating therewith to simultaneously clean both sides of the aluminum template 1, and when the rotating support assembly 4 is in a working state, the aluminum template 1 is driven in a vertical state so that both sides of the aluminum template 1 are exposed to the outside to cooperate with the flushing assembly 5 for flushing operation.

[0021] The conveying mechanism 3 is provided in both the external isolation chamber 21 and the internal dynamic cleaning chamber 22. The cleaning chamber 2 is provided with a transfer component capable of transferring the preliminarily decontaminated aluminum template 1 from the external isolation chamber 21 to the internal dynamic cleaning chamber 22. The transfer component is not shown in the figure.

[0022] The external isolation chamber 21 is provided with a nozzle assembly for achieving a preliminary decontamination effect on the aluminum template 1 , and the nozzle assembly is not shown in the figure.

[0023] When the aluminum template 1 is cleaned, it is first sent to the external isolation chamber 21 through the conveying mechanism 3 set in the cleaning chamber 2. At this stage, the conveying mechanism 3 conveys the aluminum template 1 horizontally to the bottom of the nozzle assembly in the external isolation chamber 21. The nozzle assembly is pre-set with multiple groups of high-pressure nozzles to spray cleaning liquid or water flow to the surface of the aluminum template 1 from different angles, thereby achieving preliminary decontamination treatment of the surface of the aluminum template 1. Large particles of impurities and some oil stains attached to the surface of the aluminum template 1 are removed, laying the foundation for subsequent more detailed cleaning. With the continuous operation of the conveying mechanism 3, the aluminum template 1 gradually passes through the external isolation chamber 21, ensuring that the surface of the aluminum template 1 exposed to the outside is uniformly cleaned.

[0024] After the initial decontamination is completed, the aluminum template 1 enters the transfer stage. At this time, the transfer component in the cleaning chamber 2 starts to work, and transfers the aluminum template 1 that has undergone initial decontamination from the external isolation chamber 21 to the internal dynamic cleaning chamber 22. The transfer component ensures a smooth transition of the aluminum template 1 between the two chambers, while avoiding the possibility of secondary contamination caused by interference from the external environment. After the transfer is completed, the aluminum template 1 is placed on the conveying mechanism 3 in the internal dynamic cleaning chamber 22, ready to enter the further cleaning stage.

[0025] In the internal dynamic cleaning chamber 22, the rotating support assembly 4 is started to adjust the aluminum template 1, which was originally placed horizontally, to a vertical state. This allows both sides of the aluminum template 1 to be fully exposed to the outside, facilitating the subsequent flushing operation. At the same time, the flushing assembly 5 starts working, covering every corner of the aluminum template 1. This allows the cleaning liquid to penetrate deeper into the tiny grooves or gaps on the surface of the aluminum template 1, further improving the cleaning quality.

[0026] During the entire dynamic cleaning process, a closed cleaning environment is formed in the internal dynamic cleaning chamber 22 to prevent the intrusion of external dust or impurities. The wastewater generated during the cleaning process will be centrally processed through the collection system at the bottom of the cleaning bin 2. The cleaning liquid or water flow is circulated in the chamber and continuously purified by the filtration system to ensure the cleaning quality while reducing resource waste. As the aluminum template 1 gradually completes the all-round cleaning, the aluminum template 1 is sent out of the internal dynamic cleaning chamber 22 and enters the subsequent process.

[0027] See also Figure 2-Figure 7 As shown, the flushing assembly 5 includes pressure rollers 51 symmetrically arranged on both sides of the rotating support assembly 4, each of the pressure rollers 51 is provided with a plurality of high-pressure nozzles 52 at equal intervals along its axial direction, and the two pressure rollers 51 are both capable of moving along the vertical direction of the aluminum template 1, and both ends of each pressure roller 51 extend horizontally to the side area of ​​the aluminum template 1.

[0028] The pressure roller 51 has a pipeline connected to each of the high-pressure nozzles 52 .

[0029] When the aluminum template 1 is adjusted to a vertical state by the rotating support component 4, the flushing component 5 starts to work. The two pressure rollers 51 start from the top position of the aluminum template 1, and the high-pressure nozzle 52 sprays the cleaning liquid to the surface of the aluminum template 1 at a preset pressure and flow rate. Since both ends of the pressure roller 51 extend horizontally to the side area of ​​the aluminum template 1, the high-pressure nozzle 52 can fully cover the front and back of the aluminum template 1 to ensure that there is no blind spot for cleaning.

[0030] As the pressing roller 51 slowly moves downward in the vertical direction, the cleaning liquid evenly washes the surface of the aluminum template 1, deeply removing the residual pollutants. After completing a top-to-bottom cleaning, the pressing roller 51 can return to the top to start a new round of cleaning until the surface of the aluminum template 1 reaches the desired cleanliness.

[0031] See also Figure 3-Figure 7 As shown, each pressing roller 51 is provided with a flexible layer 511 capable of contacting the surface of the aluminum template 1. When the pressing roller 51 moves up and down along the surface of the aluminum template 1, the flexible layer 511 is in an extrusion state against the surface of the aluminum template 1, so that the aluminum template 1 is stably clamped while the attached dirt and residual liquid are scraped off.

[0032] When the pressing roller 51 moves up and down along the surface of the aluminum template 1, the flexible layer 511 on the pressing roller 51 keeps in contact with the surface of the aluminum template 1 and is in a slightly squeezed state, which not only stably clamps the aluminum template 1 to prevent it from shaking during the dynamic cleaning process, but also effectively scrapes off dirt and residual liquid attached to the surface.

[0033] Specifically, as the pressure roller 51 moves downward from the top of the aluminum template 1, the flexible layer 511 closely adheres to the surface of the aluminum template 1 under pressure, and gradually removes the water stains, impurities and insoluble pollutants remaining after the high-pressure nozzle 52 is sprayed. At the same time, the flexible layer 511 ensures that it will not scratch or damage the surface of the aluminum template 1, which not only improves the cleaning effect, but also protects the integrity of the aluminum template 1.

[0034] See also Figure 2-Figure 7 and Fig.10 As shown, the flushing assembly 5 also includes a rotating guide rail 53 that can drive the pressure rollers 51 to gradually approach when the aluminum template 1 is in a vertical state. Each pressure roller 51 is slidably set on one of the rotating guide rails 53. A support 531 for rotatably connecting the rotating guide rail 53 is provided in the internal dynamic cleaning chamber 22. The rotating guide rail 53 is provided with a stopper 532 that cooperates with the support 531 to ensure that the rotating guide rail 53 is parallel to the surface of the aluminum template 1.

[0035] The support 531 is provided with a swing drive for driving the rotating guide rail 53 to rotate, and the swing drive is not shown in the figure.

[0036] When the aluminum template 1 is in a vertical state, the rotating guide rail 53 in the flushing assembly 5 starts to work through the swing drive, gradually driving the two pressure rollers 51 close to the surface of the aluminum template 1.

[0037] When the rotating guide rail 53 swings downward to a vertical state, the support 531 blocks the stop block 532, so that the rotating guide rail 53 cannot continue to swing, thereby ensuring that the rotating guide rail 53 is parallel to the surface of the aluminum template 1 in a vertical state, thereby ensuring that the pressure roller 51 can always move in a direction parallel to the aluminum template 1.

[0038] This ensures that the pressure roller 51 always operates at the correct angle and direction when moving along the surface of the aluminum template 1, thereby avoiding poor cleaning effect due to angle deviation or damage to the surface of the aluminum template 1 due to excessive pressure.

[0039] See also Figure 4-Figure 7 and Fig.10 As shown, a sliding seat 54 capable of driving the pressure roller 51 to move along its length direction is provided on the rotating guide rail 53 , and the pressure roller 51 can rotate on the sliding seat 54 toward the direction of the aluminum template 1 to adjust the angle of the high-pressure nozzle 52 .

[0040] The rotary guide rail 53 is provided with a linear drive for driving the sliding seat 54 to move, and the linear drive is not shown in the figure.

[0041] The sliding seat 54 is provided with an angle adjustment driver for driving the pressing roller 51 to rotate, and the angle adjustment driver is not shown in the figure.

[0042] During the cleaning process, the linear drive on the rotating guide rail 53 is activated, driving the sliding seat 54 to move along the length direction of the rotating guide rail 53, so that the pressure roller 51 moves along the surface of the aluminum template 1. As the sliding seat 54 continues to move, the high-pressure nozzle 52 on the pressure roller 51 fully rinses the aluminum template 1. At the same time, the angle adjustment driver on the sliding seat 54 starts to work, driving the pressure roller 51 to rotate around its axis to accurately adjust the angle of the high-pressure nozzle 52 to ensure that the sprayed water can cover the surface of the aluminum template 1 at the best angle.

[0043] See also Figure 4-Figure 9 and Fig.11 As shown, the rotating support assembly 4 includes a rotating shaft 41 and a plurality of clamps 42 evenly distributed around the rotating shaft 41. The rotating shaft 41 is provided with a clamp 42 near both ends thereof, and each of the clamps 42 can move along the axial direction of the rotating shaft 41 to fully expose the surface of the aluminum template 1.

[0044] The internal dynamic cleaning chamber 22 is provided with a rotary drive that can drive the rotary shaft 41 to rotate. The rotary drive drives the rotary shaft 41 to rotate intermittently. Every time the rotary shaft 41 rotates an angle, an aluminum template 1 is driven by the clamp 42 to enter between the two pressure rollers 51 in a vertical state.

[0045] When the rotating shaft 41 rotates a fixed angle each time, one of the clamps 42 drives the aluminum template 1 to move to a vertical state and as the clamp 42 moves away from the aluminum template 1, it is completely exposed between the two pressing rollers 51, ensuring that both sides of the aluminum template 1 can be fully washed.

[0046] See also Figure 3-Figure 7 and Fig.11 As shown, a rubber strip 411 for supporting the aluminum template 1 is provided on the rotating shaft 41 and between each two corresponding clamps 42, and a rubber roller 412 is provided on the support 531 so as to be opposite to one of the rubber strips 411 at a time. When the aluminum template 1 is rotated to a vertical state, the aluminum template 1 is clamped between the rubber strip 411 and the rubber roller 412.

[0047] During the cleaning process, when the rotating shaft 41 drives the clamps 42 to rotate the aluminum template 1 to a vertical state, the rubber strip 411 between each two corresponding clamps 42 is directly opposite to the rubber roller 412 on the support 531. At this time, the aluminum template 1 is accurately fed between the rubber strip 411 and the rubber roller 412, and stable clamping is achieved through the flexible contact between the two.

[0048] The combination of the rubber strip 411 and the rubber roller 412 not only ensures the stability of the aluminum template 1 in a vertical state, preventing it from deflecting or shaking during high-pressure washing, but also effectively prevents hard contact from causing damage to the edge of the aluminum template 1. While the aluminum template 1 is clamped, the clamp 42 can be kept away from the aluminum template 1, and the aluminum template 1 can be kept in the best cleaning posture, ensuring that the high-pressure nozzle 52 on the pressure roller 51 can cover the surface of the aluminum template 1 in an all-round and uniform manner, thereby achieving an efficient and high-quality cleaning effect.

[0049] See also Figure 5-Figure 9 and Fig.11 As shown, the clamp 42 is composed of two clamps 421, and a slide rail 422 is provided on the rotating shaft 41 along its axial direction for each clamp 421 to slide. The rotating shaft 41 is also provided with a pusher 43 that can drive the two clamps 421 to move outward away from the aluminum template 1 at the same time, and a reset connector 44 is provided between each clamp 421 and the rotating shaft 41.

[0050] Each clamp plate 421 is provided with a guide rod 441 extending outward along the axial direction of the rotating shaft 41. The end of the rotating shaft 41 has an end 413 for the guide rod 441 to pass through. The reset connector 44 is specifically a compression spring that is sleeved on the guide rod 441 and connected between the clamp plate 421 and the end 413.

[0051] The pusher 43 is composed of a first electromagnet 431 and a second electromagnet 432, wherein the first electromagnet 431 is fixedly connected to the end 413, and the second electromagnet 432 is fixedly connected to two guide rods 441. When the first electromagnet 431 and the second electromagnet 432 are energized and repel each other, the second electromagnet 432 moves away from the first electromagnet 431, so that the clamping plate 421 moves away from the aluminum template 1, thereby exposing its surface. This is conducive to comprehensive cleaning of the aluminum template 1.

[0052] After the cleaning is completed, the first electromagnet 431 and the second electromagnet 432 are powered off, the compression spring recovers its elastic force, and the clamping plate 421 is pushed back to its original position, and the aluminum template 1 is clamped again to ensure that it stably enters the next process.

[0053] See also Figure 5-Figure 7 and Fig.11 As shown, a pressure sensor is provided between the rubber roller 412 and the support 531, and the pressure sensor is electrically connected to the pusher 43. When the rubber roller 412 is squeezed by the aluminum template 1, the pressure sensor detects the pressure change, so that the pusher 43 pushes the clamp 42 in which the aluminum template 1 to be cleaned is clamped in the direction away from the aluminum template 1.

[0054] The pressure sensor is not shown in the figure.

[0055] When the aluminum template 1 is rotated to a vertical state and enters between the rubber roller 412 and the rubber strip 411, the rubber roller 412 is squeezed by the aluminum template 1, and the pressure sensor detects the pressure change. The pressure sensor immediately transmits a signal to the pusher 43, triggering it to start. The two clamping plates 421 of the push clamp 42 move outward along the slide rail 422, away from the aluminum template 1, so that the surface of the aluminum template 1 is completely exposed, which is convenient for the high-pressure nozzle 52 on the pressure roller 51 to clean it in all directions.

[0056] A double-layer isolated dynamic cleaning method for anodizing an aluminum mold is applied to the double-layer isolated dynamic cleaning device for anodizing an aluminum mold described above, comprising the following steps: S1, the aluminum template 1 is sent into the external isolation chamber 21 through the conveying mechanism 3, and the nozzle assembly is used for preliminary decontamination treatment to remove large particles of impurities and some oil stains on the surface; S2, the aluminum template 1 after preliminary cleaning is transferred from the transfer assembly to the internal dynamic cleaning chamber 22, and is placed on the rotating support assembly 4 and adjusted to a vertical state; S3, the pressure roller 51 in the flushing component 5 moves along the surface of the aluminum template 1, the high-pressure nozzle 52 fully covers the front and back sides for deep cleaning, and the flexible layer 511 scrapes off the residue simultaneously.

[0057] After the present invention adjusts the aluminum template 1 to a vertical state by rotating the support component 4, the pressure roller 51 in the flushing component 5 uses the high-pressure nozzle 52 to fully cover the front and back sides of the aluminum template 1 for cleaning. At the same time, the flexible layer 511 on the pressure roller 51 stably clamps the aluminum template 1 under a slight squeezing state to prevent shaking and effectively scrape off residues.

[0058] During this process, the clamp 42 is away from the aluminum template 1, and the rubber strip 411 and the rubber roller 412 further improve the stability of the aluminum template 1 during the cleaning process, so that both sides of the aluminum template 1 are completely exposed between the pressure rollers 51, achieving all-round and efficient cleaning.

[0059] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
