Description

Technical Field

[0001] The present invention relates to the technical field related to cleaning equipment, and in particular to a cleaning equipment for aluminum alloy processing and an operating method thereof. Background Art

[0002] The core goal of aluminum alloy cleaning is to completely remove the oil, scale, dust and other stains attached to its surface, thereby significantly improving the aesthetics, material quality and durability of aluminum alloy. At present, the cleaning operation of aluminum alloy plates generally adopts the automated assembly line operation mode, that is, the plate is placed stably on the conveyor roller, and the upper and lower surfaces of the plate are fully and effectively brushed with the help of the brush body structure configured above and below.

[0003] However, in actual application, due to the diversity of thickness of aluminum alloy plates, higher requirements are placed on the spacing adjustment of the brushes. Unfortunately, the currently widely used brush roller design mostly has a fixed spacing adjustment method, which lacks sufficient flexibility and adaptability and is difficult to meet the cleaning needs of plates of different thicknesses. This fixed spacing design not only limits the cleaning equipment's ability to handle plates of multiple thicknesses, but also leads to a significant reduction in cleaning efficiency. Because every time a plate of different thickness needs to be replaced, the operator needs to manually adjust the spacing of the brushes, a step that is not only time-consuming and labor-intensive, but may also affect the cleaning effect due to improper adjustment, and even cause damage to the surface of the plate. Summary of the invention

[0004] The present invention provides a cleaning device for aluminum alloy processing and an operating method thereof, which has the advantage of adaptively adjusting the brush roller spacing, and is used to solve the problem that the brush roller spacing is difficult to adjust in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cleaning device for aluminum alloy processing, comprising: a supporting base, on the surface of which is mounted a feed roller for conveying aluminum alloy plates; a cleaning bottom roller, mounted on the supporting base and driven by a motor fixed on the supporting base, with a driving gear fixed at the end of the cleaning bottom roller; a central shaft, mounted on the supporting base and located above the cleaning bottom roller, with a driven gear meshing with the outer teeth of the driving gear mounted at the end, and a cleaning top roller connected to the outside through a distance-adjusting top spring.

[0006] Furthermore, brushes are arranged on the outer sides of the cleaning bottom roller and the cleaning top roller.

[0007] Furthermore, a rear guide frame is fixedly installed on the support base, a rear pressure plate is installed on the rear guide frame, and a tension spring is connected between the rear pressure plate and the rear guide frame; a fixed magnetic block is fixedly installed on the bottom of the rear guide frame, and a movable magnetic block magnetically attracted to the fixed magnetic block is fixedly installed on the end of the rear pressure plate; a guide tooth row is movably installed on one side of the support base, and the guide tooth row is meshed with a local gear fixed on the end of the driving gear, a magnetic isolation baffle is installed on the end of the guide tooth row, and a reset push spring is connected between the guide tooth row and the support base.

[0008] Furthermore, a front guide frame is fixedly installed on the support base, and a front pressure plate is movably installed in the front guide frame. A synchronous connecting frame is fastened to the top of the front pressure plate, and the other end of the synchronous connecting frame is connected to the rear pressure plate by magnetic attraction of the movable magnetic block.

[0009] Furthermore, a limited motion push rod is movably installed at the end of the front pressure plate, and an adjusting screw is threadedly connected to the top of the limited motion push rod, and a limited motion spring is connected between the adjusting screw and the front pressure plate.

[0010] Furthermore, the tooth shape of the guide tooth row is an isosceles right triangle.

[0011] Furthermore, a limiting bolt for blocking the magnetic isolation baffle is threadedly connected to the support base.

[0012] Furthermore, a damping hydraulic cylinder is connected to the front guide frame, a damping piston rod is movably installed inside the damping hydraulic cylinder, and the top of the damping piston rod is fixedly connected to the synchronous connecting frame; a buffer chamber is opened inside the damping hydraulic cylinder, and a damping hole and a one-way valve communicating with the buffer chamber are opened at the bottom of the damping hydraulic cylinder.

[0013] Furthermore, hydraulic oil is injected into the buffer chamber, a driving hydraulic cylinder is fixedly connected to the rear guide frame, a driving piston rod is movably installed in the driving hydraulic cylinder, and the hydraulic chamber inside the driving hydraulic cylinder is connected to the buffer chamber via a hydraulic delivery pipe.

[0014] An operating method of a cleaning device for aluminum alloy processing comprises the following steps:

[0015] S1. Place the aluminum alloy plate to be cleaned on the feed roller;

[0016] S2, through the conveying action of the feeding roller, the plate is smoothly and continuously transported to the area between the cleaning bottom roller and the cleaning top roller;

[0017] S3, spraying the cleaning liquid between the cleaning bottom roller and the cleaning top roller through an external cleaning liquid spraying mechanism;

[0018] S4, using the thickness of the plate itself, forces the cleaning top roller to move upward and compresses the distance adjusting top spring;

[0019] S5, the motor drives the cleaning bottom roller to rotate, and through the meshing transmission of the driving gear and the driven gear, further drives the cleaning top roller to rotate synchronously;

[0020] S6. With the synchronous rotation of the cleaning bottom roller and the cleaning top roller, the surface of the plate is effectively scrubbed and transported forward with the rotation of the rollers;

[0021] S7, until the aluminum alloy plate completely passes through the area between the cleaning bottom roller and the cleaning top roller, the cleaning work of the plate is completed.

[0022] The present invention has the following beneficial effects:

[0023] The present invention provides a cleaning device for aluminum alloy processing and an operating method thereof. The device adopts a precise meshing transmission mode of a driving gear and a driven gear to drive the aluminum alloy plate to be not only effectively scrubbed during the cleaning process, but also smoothly transported backward. This design ensures the high efficiency and continuity of the cleaning operation.

[0024] Furthermore, the core part of the cleaning device is composed of a cleaning bottom roller and a cleaning top roller, which form an adjustable cleaning channel. The cleaning top roller is not fixedly installed, but is connected to the central axis through a spacing top spring. When the aluminum alloy sheet is fed into this cleaning channel, the thickness of the sheet itself will naturally exert an upward pressure on the cleaning top roller, forcing the cleaning top roller to move upward along the central axis and compress the spacing top spring. This process not only ensures that the sheet can smoothly pass through the narrow gap between the cleaning bottom roller and the cleaning top roller, but also realizes the dynamic adjustment of the cleaning channel spacing through the elastic feedback of the spacing top spring.

[0025] The design of the adjustable top spring allows the spacing between the bottom cleaning roller and the top cleaning roller to be flexibly adjusted within a preset range, thus meeting the cleaning requirements of aluminum alloy plates of various specifications from thin to thick. This adaptive adjustment mechanism ensures that a uniform and effective scrubbing effect can be obtained regardless of the thickness of the plate, avoiding uneven cleaning or equipment damage caused by differences in plate thickness.

[0026] In summary, the aluminum alloy processing and cleaning equipment successfully realizes adaptive cleaning of aluminum alloy plates of different thicknesses by combining precise gear transmission, innovative adjustable top spring design and efficient brushing system, greatly improving the cleaning efficiency and cleaning quality, and bringing significant technological progress to the aluminum alloy processing industry.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For example, see Figure 1It can be seen that the support base 1 can be fixed at a desired position by using the cylindrical hole reserved at the bottom. Multiple feed rollers 2 are movably mounted on the support base 1. It should be noted that the multiple feed rollers 2 can be synchronously rotated by means of belts or chains (the transmission structure diagram is not shown in the figure), so that the aluminum alloy plate placed on the feed rollers 2 can be transported forward, and the transportation of the aluminum alloy plate is completed.

[0039] A cleaning bottom roller 3 driven by a motor 4 is installed in the support base 1. The motor 4 is generally fastened to the support base 1. Figure 2 It can be seen that a driving gear 14 is coaxially fixedly installed at the end of the cleaning bottom roller 3. Correspondingly, a central shaft 6 located above the cleaning bottom roller 3 is movably installed on the support base 1, and a driven gear 16 meshing with the outer teeth of the driving gear 14 is coaxially fixedly installed at the end of the central shaft 6. In addition, a cleaning top roller 5 connected to the outside of the central shaft 6 via a spacing adjustment top spring 600 is provided, and the cleaning top roller 5 is located on the outside of the central shaft 6. Figure 2 It can be clearly seen that there are multiple distance-adjusting top springs 600, which can generally be divided into six groups, each of which has four distance-adjusting top springs 600, and the distance-adjusting top springs 600 in each group are arranged in a circular shape with the axis of the central axis 6 as the center. The advantage of this design is that when the aluminum alloy plate passes between the cleaning bottom roller 3 and the cleaning top roller 5, the cleaning top roller 5 can compress the distance-adjusting top spring 600 due to the thickness of the plate, thereby ensuring that the aluminum alloy plate can pass normally through the reserved gap between the cleaning bottom roller 3 and the cleaning top roller 5. More specifically, brushes are generally provided on the outside of the cleaning bottom roller 3 and the cleaning top roller 5 to scrub the aluminum alloy plate passing through, thereby removing oil, scale, dust and other types of stains attached to the surface of the aluminum alloy.

[0040] In actual application, the external cleaning liquid is sprayed between the cleaning bottom roller 3 and the cleaning top roller 5 (the spray mechanism is not shown in the figure, and a general spray head that can meet the liquid medium spraying requirements can be used), and the aluminum alloy plate to be cleaned is placed on the feed roller 2, and the feed roller 2 is used to transport the plate to the cleaning bottom roller 3 and the cleaning top roller 5. When the plate passes through the cleaning bottom roller 3 and the cleaning top roller 5, the cleaning top roller 5 is forced to move upward and compress the distance adjustment top spring 600 due to the thickness of the plate itself, so that the distance between the cleaning bottom roller 3 and the cleaning top roller 5 is adapted to the thickness of the aluminum alloy plate.

[0041] When the motor 4 drives the cleaning bottom roller 3 to rotate, the cleaning bottom roller 3, through the meshing transmission of the driving gear 14 and the driven gear 16, forces the central shaft 6 to drive the cleaning top roller 5 to rotate synchronously according to the adjustable top spring 600. The surface of the plate is scrubbed and conveyed forward by the rotation of the cleaning bottom roller 3 and the cleaning top roller 5. Until the aluminum alloy plate completely passes between the cleaning bottom roller 3 and the cleaning top roller 5, the cleaning work of the aluminum alloy plate is completed.

[0042] The second embodiment is further improved on the basis of the first embodiment. In order to extend the cleaning time of the bottom cleaning roller 3 and the top cleaning roller 5 for the aluminum alloy plate, please refer to Figure 1 , Figure 3 and Figure 4 It can be seen that a rear guide frame 9 located at the sheet material output position between the cleaning bottom roller 3 and the cleaning top roller 5 is fixedly installed on the support base 1, and a rear pressure plate 11 is installed on the rear guide frame 9. Specifically, the rear pressure plate 11 can only perform vertical up and down reciprocating motion along the rear guide frame 9. When the aluminum alloy sheet moves to the bottom of the rear pressure plate 11, the aluminum alloy sheet is pressed by the rear pressure plate 11, thereby restricting the movement of the sheet. In addition, in order to achieve the clamping / relaxation of the sheet by the rear pressure plate 11, three tension springs 10 are connected between the rear pressure plate 11 and the rear guide frame 9. Under the pull of the elastic force of the tension spring 10, the tension spring 10 always has a tendency to pull the rear pressure plate 11 upward, thereby achieving the upward movement of the rear pressure plate 11, thereby releasing the pressure on the aluminum alloy sheet; in contrast, combined with Figure 5 It can be clearly seen that a fixed magnet 25 is fixedly installed at the bottom of the rear guide frame 9, and a movable magnet 26 located above the fixed magnet 25 is fixedly installed at the end of the rear pressure plate 11. The fixed magnet 25 and the movable magnet 26 are magnetically attracted to each other, and the magnetic attraction force between the two is greater than the elastic tension of the tension spring 10, thereby ensuring that the movable magnet 26 has a tendency to pull the rear pressure plate 11 downward under the magnetic attraction of the fixed magnet 25.

[0043] The guide tooth row 17 is movably arranged on one side of the support base 1 and is located near the end of the rear pressure plate 11. Figure 2-Figure 4It can be seen that the local gear 15 is coaxially mounted on the driving gear 14, and the outer teeth on the local gear 15 mesh with the guide gear row 17. When the local gear 15 rotates with the driving gear 14, the outer teeth of the local gear 15 can be used to drive the guide gear row 17 to move linearly, thereby driving the magnetic shielding baffle 18 fastened to the guide gear row 17 by bolts to move toward the fixed magnetic block 25, until the magnetic shielding baffle 18 blocks the fixed magnetic block 25, thereby blocking the magnetic attraction between the fixed magnetic block 25 and the movable magnetic block 26. Since a reset spring 170 is connected between the guide gear row 17 and the support base 1, when the outer teeth of the local gear 15 are away from the guide gear row 17, the guide gear row 17 and the local gear 15 are no longer in contact, and under the push of the elastic force of the reset spring 170, the guide gear row 17 is forced to drive the magnetic shielding baffle 18 to move away from the fixed magnetic block 25, thereby removing the blocking of the relative magnetic surfaces between the fixed magnetic block 25 and the movable magnetic block 26.

[0044] In actual application, the motor 4 drives the cleaning bottom roller 3 and the cleaning top roller 5 to rotate synchronously. Moreover, when the driving gear 14 drives the local gear 15 to rotate, the outer teeth of the local gear 15 and the guide tooth row 17 are periodically meshed. When the outer teeth on the local gear 15 are not meshed with the guide tooth row 17, the guide tooth row 17 is pushed by the elastic force of the reset push spring 170 to make the magnetic shielding baffle 18 relatively away from the fixed magnetic block 25. At this time, the relative magnetic surface between the fixed magnetic block 25 and the movable magnetic block 26 is not blocked, and the rear pressure plate 11 is forced to move downward by the magnetic attraction between the two. The downward rear pressure plate 11 will eventually press on the aluminum alloy plate that has been cleaned between the cleaning bottom roller 3 and the cleaning top roller 5. Since the plate is pressed by the rear pressure plate 11 at this time, the resistance to its movement is relatively increased. When the cleaning bottom roller 3 and the cleaning top roller 5 rotate, relative sliding will occur between the aluminum alloy plate, thereby extending the time for brushing the aluminum alloy plate between the cleaning bottom roller 3 and the cleaning top roller 5. As the driving gear 14 drives the local gear 15 to rotate continuously, the outer teeth of the local gear 15 will mesh with the guide gear row 17. The meshed guide gear row 17 will compress the reset spring 170 and drive the magnetic isolation baffle 18 to move between the fixed magnetic block 25 and the movable magnetic block 26 under the influence of the rotation of the local gear 15, thereby isolating the magnetic attraction between the fixed magnetic block 25 and the movable magnetic block 26. Afterwards, under the elastic force of the tension spring 10, the rear pressure plate 11 tends to move upward, thereby releasing the pressure on the aluminum alloy plate. With the continuous rotation between the cleaning bottom roller 3 and the cleaning top roller 5, the aluminum alloy plate will be moved a certain distance. When the local gear 15 rotates and disengages from the guide gear row 17, under the elastic force of the reset spring 170, the guide gear row 17 drives the magnetic isolation baffle 18 away from the fixed magnetic block 25 and releases the obstruction between the fixed magnetic block 25 and the movable magnetic block 26. The fixed magnetic block 25 and the movable magnetic block 26 are moved downward again under the magnetic attraction and press the aluminum alloy plate, thereby limiting the movement of the aluminum alloy plate. This cycle is repeated to increase the cleaning time of the aluminum alloy plate.

[0045] On this basis, combined with Figure 1 and Figure 3 It can be clearly seen that a front guide frame 7 located at the sheet material input position between the cleaning bottom roller 3 and the cleaning top roller 5 is fixedly installed on the support base 1, and a front pressure plate 8 is movably installed in the front guide frame 7. Through the restriction of the front guide frame 7, the front pressure plate 8 can only reciprocate up and down along the front guide frame 7. In addition, referring to Figure 3 , Figure 5 and Figure 6It can be clearly seen that there is a synchronous connecting frame 12 fastened by bolts on the top of the front pressure plate 8. The shape of the synchronous connecting frame 12 is U-shaped, one end of which is used for fixed connection with the front pressure plate 8, and the other end is magnetically attracted by the movable magnetic block 26, so as to realize the magnetic connection between the synchronous connecting frame 12 and the rear pressure plate 11. In actual application, when the rear pressure plate 11 moves up and down, the front pressure plate 8 will be driven to move up and down synchronously by the transmission of the synchronous connecting frame 12, so as to ensure that when the rear pressure plate 11 presses the plate, the front pressure plate 8 will also press the plate, so as to ensure that the aluminum alloy plate is pressed and limited before and after brushing, so as to avoid the plate from moving during the brushing process of the cleaning bottom roller 3 and the cleaning top roller 5, resulting in the problem of its position shifting.

[0046] The third embodiment is a further improvement on the second embodiment. The third embodiment aims to realize that the brushing time between the bottom cleaning roller 3 and the top cleaning roller 5 can be controlled for the aluminum alloy plate. Figure 3 and Figure 6 It can be seen that a limited push rod 20 is movably installed at the end of the front pressure plate 8, and an adjustment screw 21 is threadedly connected to the top of the limited push rod 20. Specifically, a limited spring 22 is connected between the adjustment screw 21 and the front pressure plate 8. When the front pressure plate 8 moves downward, the limited push rod 20 will be driven to move downward synchronously until the bottom of the limited push rod 20 reaches the guide gear row 17. It should be noted that Figure 4 It can be seen from the figure that the tooth shape of the guide tooth row 17 is an isosceles right triangle, and the purpose of limiting unidirectional movement can be achieved by moving the limiting push rod 20 along the outer teeth of the guide tooth row 17.

[0047] Specifically, when the outer teeth on the local gear 15 are away from the guide gear row 17, the reset spring 170 pushes the magnetic isolation baffle 18 to also be relatively away from the fixed magnet block 25. At this time, the magnetic attraction between the fixed magnet block 25 and the movable magnet block 26 forces the rear pressure plate 11 and the front pressure plate 8 to move downward synchronously, and finally press the aluminum alloy plate. At the same time, the downward movement of the front pressure plate 8 will drive the limit push rod 20 to move downward synchronously until the limit push rod 20 reaches the guide gear row 17. It should be noted that since the bottom end of the limit spring 22 is fixedly connected to the front pressure plate 8 and the top is fixedly connected to the adjustment screw 21, when the limit push rod 20 reaches the guide gear row 17, the front pressure plate 8 that continues to move downward will drag the limit spring 22 to stretch synchronously, so as to ensure that the limit push rod 20 always reaches the outer teeth of the guide gear row 17.

[0048] Afterwards, as the motor 4 drives the cleaning bottom roller 3 and the cleaning top roller 5 to rotate synchronously, the upper and lower surfaces of the aluminum alloy plate are brushed. At the same time, when the driving gear 14 drives the local gear 15 to move, the outer teeth of the local gear 15 will push the guide gear row 17 to move, so that the magnetic isolation baffle 18 is close to the fixed magnetic block 25. At this time, when the guide gear row 17 moves horizontally, the outer tooth inclined surface of the guide gear row 17 will push the limit push rod 20 upward and further stretch the limit spring 22. When the limit push rod 20 passes over the outer teeth of the guide gear row 17, it will hit the right angle surface of the outer teeth, thereby limiting the guide gear row 17 from being reset under the elastic force of the reset push spring 170. This cycle is repeated until the local gear 15 rotates to the set number of turns, and the magnetic isolation baffle 18 will move between the fixed magnetic block 25 and the movable magnetic block 26, thereby blocking the fixed magnetic block 25 and the movable magnetic block 26. At the same time, the rear pressure plate 11 will drive the front pressure plate 8 upward synchronously under the elastic force of the tension spring 10, and the front pressure plate 8 will eventually drive the limit push rod 20 away from the guide gear row 17, so that the limit push rod 20 releases the movement restriction of the guide gear row 17. When the driven gear 16 is separated from the guide gear row 17, it is reset under the elastic force of the reset push spring 170. Afterwards, the magnetic attraction between the fixed magnetic block 25 and the movable magnetic block 26 forces the rear pressure plate 11 to drive the front pressure plate 8 downward synchronously, and the limit push rod 20 is pressed on the guide gear row 17 again, and the cycle is repeated, thereby further extending the brushing time of the cleaning bottom roller 3 and the cleaning top roller 5 on the aluminum alloy plate.

[0049] The following detailed explanation is given for the rotation of the local gear 15 mentioned above to the set number of revolutions. Figure 3 It can be seen that the rotation of the local gear 15 will force the guide gear row 17 to pull the magnetic isolation baffle 18 to move a rated distance in the direction of the fixed magnetic block 25. In order to achieve the above purpose, it is only necessary to control the distance between the magnetic isolation baffle 18 and the fixed magnetic block 25. Specifically, a limit bolt 19 is threadedly connected to the support base 1 to block the magnetic isolation baffle 18. The limit bolt 19 is used to limit the return distance of the magnetic isolation baffle 18 to ensure that the length between the magnetic isolation baffle 18 and the fixed magnetic block 25 remains consistent after recovery. This requires that the local gear 15 rotates to the rated number of turns before the magnetic isolation baffle 18 can move to the fixed magnetic block 25.

[0050] The fourth embodiment is a supplement to the third embodiment. In order to prevent the magnetic barrier 18 from separating from the fixed magnetic block 25 at the moment, the magnetic attraction between the fixed magnetic block 25 and the movable magnetic block 26 forces the rear pressure plate 11 to drag the front pressure plate 8 downward quickly, resulting in the guide gear row 17 not yet pushing the magnetic barrier 18 to the limit bolt 19, and the limit push rod 20 has already moved downward and limited the movement of the guide gear row 17. In order to prevent such a phenomenon from occurring, the fourth embodiment is provided. Please refer to Figure 3 , Figure 6 and Figure 7It can be seen that the front guide frame 7 is provided with a damping hydraulic cylinder 13 connected to the bottom of the synchronous connecting frame 12 through a clamp, and a damping piston rod 131 is movably installed inside the damping hydraulic cylinder 13. When the damping piston rod 131 moves up and down inside the damping hydraulic cylinder 13, the pressure inside the damping hydraulic cylinder 13 can be changed. The top of the damping piston rod 131 is fixedly connected to the synchronous connecting frame 12, so as to ensure that the damping piston rod 131 can move synchronously with the synchronous connecting frame 12. Furthermore, a return spring 27 is connected between the damping hydraulic cylinder 13 and the damping piston rod 131. Under the push of the elastic force of the return spring 27, the damping piston rod 131 is forced to always have a tendency to drag the synchronous connecting frame 12 downward.

[0051] More importantly, a damping hole 132 is provided at the bottom of the damping hydraulic cylinder 13. When the pressure of the medium in the buffer chamber 130 provided inside the damping hydraulic cylinder 13 changes, a damping effect can be generated through the damping hole 132, thereby buffering the pressure change in the buffer chamber 130. At the same time, a one-way valve 133 located on one side of the damping hole 132 is fixedly installed at the bottom of the damping hydraulic cylinder 13. The one-way valve 133 realizes one-way delivery of the external medium into the buffer chamber 130, thereby ensuring that when the pressure in the buffer chamber 130 decreases, the external medium can be quickly replenished into the buffer chamber 130. Taking air medium as an example, when the magnetic isolation baffle 18 moves between the fixed magnetic block 25 and the movable magnetic block 26, the relative magnetic surfaces between the two will be blocked, and the front pressure plate 8 and the synchronous connecting frame 12 will be forced to move upward synchronously under the elastic force of the tension spring 10. At the same time, when the synchronous connecting frame 12 drives the damping piston rod 131 to move upward, the pressure in the buffer chamber 130 will be reduced, and the external airflow will be quickly injected into the buffer chamber 130 from the one-way valve 133. Afterwards, when the magnetic isolation baffle 18 moves away from the fixed magnetic block 25, the magnetic attraction between the fixed magnetic block 25 and the movable magnetic block 26 will force the movable magnetic block 26 to drag the rear pressure plate 11 downward quickly and press it on the surface of the aluminum alloy plate. At this time, since the damping piston rod 131 is subjected to the downward pressure of the synchronous connecting frame 12 and the elastic force of the reset spring 27, the damping piston rod 131 is forced to squeeze the air in the buffer chamber 130, and the air in the buffer chamber 130 can only be slowly discharged from the damping hole 132, which causes the synchronous connecting frame 12 and the front pressure plate 8 to move downward at a relatively lower speed than the rear pressure plate 11. Combined with the synchronous connecting frame 12 and the rear pressure plate 11 being connected by the magnetic attraction of the active magnetic block 26, the synchronous connecting frame 12 subjected to resistance will separate from the active magnetic block 26, thereby ensuring the relatively low speed downward movement of the front pressure plate 8. The implementation of this method can ensure that under the push of the elastic force of the reset push spring 170, the magnetic isolation baffle 18 has enough time to move in the direction of the limit bolt 19 until the magnetic isolation baffle 18 hits the limit bolt 19. As time goes by, the front pressure plate 8 that finally moves downward will drive the limit push rod 20 to hit the guide gear row 17, thereby limiting the one-way movement of the guide gear row 17.

[0052] On this basis, hydraulic oil is injected into the buffer chamber 130 to achieve liquid medium damping and shock absorption. Specifically, Figure 5 It can be seen that the rear guide frame 9 is provided with a driving hydraulic cylinder 24 fixedly connected by a limiting base, and a driving piston rod 23 located below the rear pressure plate 11 is movably installed in the driving hydraulic cylinder 24, and the hydraulic chamber 240 inside the driving hydraulic cylinder 24 is connected to the buffer chamber 130 by a hydraulic delivery pipe. In this way, the damping and buffering effect equivalent to that of the air medium mentioned above can be achieved. Different from this, since the driving piston rod 23 is located below the rear pressure plate 11, when no aluminum alloy sheet is input between the cleaning bottom roller 3 and the cleaning top roller 5, the front pressure plate 8 follows the rear pressure plate 11 to move downward synchronously under normal conditions, and the front pressure plate 8 will block the aluminum alloy sheet from being transported between the cleaning bottom roller 3 and the cleaning top roller 5, which will obviously prolong the feeding time. In order to solve such problems, through the above arrangement, when there is no aluminum alloy sheet between the cleaning bottom roller 3 and the cleaning top roller 5, the rear pressure plate 11 will be magnetically attracted by the fixed magnetic block 25 and the movable magnetic block 26 and will continue to move downward, and the rear pressure plate 11 will be pressed against the driving piston rod 23, and the driving piston rod 23 will be used to move downward and squeeze the hydraulic oil in the hydraulic chamber 240, so that the hydraulic oil is transported to the buffer chamber 130 through the hydraulic delivery pipe, thereby pushing the damping piston rod 131 to move upward. Since the magnetic attraction strength between the fixed magnetic block 25 and the movable magnetic block 26 is greater than the magnetic attraction strength of the movable magnetic block 26 to the synchronous connecting frame 12, when the liquid oil in the buffer chamber 130 increases, it will push the synchronous connecting frame 12 to pull the front pressure plate 8 to move upward, and the upward front pressure plate 8 will not block the input aluminum alloy sheet. At this time, the limit push rod 20 will still be pressed against the guide tooth row 17 under the elastic force of the limit spring 22. At the same time, as the rear pressure plate 11 presses downward to drive the piston rod 23, the surface of the rear pressure plate 11 also moves downward relatively. When the aluminum alloy plate is conveyed between the cleaning bottom roller 3 and the cleaning top roller 5, it will not be blocked by the front pressure plate 8. After passing between the cleaning bottom roller 3 and the cleaning top roller 5, the aluminum alloy plate will hit the side of the rear pressure plate 11, thereby limiting the aluminum alloy plate from continuing to move forward.

[0053] Finally, as the cleaning bottom roller 3 drives the driving gear 14 and the local gear 15 to rotate continuously, the local gear 15 meshes with the guide gear row 17, forcing the magnetic baffle 18 to continuously approach the fixed magnetic block 25, until the magnetic baffle 18 blocks the relative magnetic surfaces of the fixed magnetic block 25 and the movable magnetic block 26, and the rear pressure plate 11 and the front pressure plate 8 move upward synchronously. Under the rotation of the cleaning bottom roller 3 and the cleaning top roller 5, the aluminum alloy plate is driven to move forward and is located below the rear pressure plate 11. When the magnetic baffle 18 is away from the fixed magnetic block 25, the rear pressure plate 11 is forced to move downward and press on the aluminum alloy plate due to the magnetic attraction of the fixed magnetic block 25 and the movable magnetic block 26. Blocked by the aluminum alloy plate, the rear pressure plate 11 will not continue to move downward to press the driving piston rod 23. Afterwards, the above content is circulated to ensure that the plate brushing time between the cleaning bottom roller 3 and the cleaning top roller 5 can be accurately controlled.
