Description

Technical Field

[0001] The invention belongs to the technical field of aluminum plate correction, and in particular relates to a plane correction device for an aluminum plate curtain wall. Background Art

[0002] Due to the unique good corrosion resistance of aluminum, it has better processing ability, pressure resistance and easy cleaning properties than glass curtain walls, which makes aluminum curtain walls widely used.

[0003] During the processing of aluminum curtain walls, the aluminum curtain walls may bend, making it impossible to ensure the flatness of the aluminum curtain walls. Therefore, a plane correction device is needed to correct the plane of the aluminum curtain walls to ensure the flatness of the aluminum curtain walls and improve their aesthetics and strength. For example, the aluminum curtain wall plane correction device proposed in patent publication number CN115464001A and the aluminum curtain wall plane correction device proposed in patent publication number CN219786077U.

[0004] The pressure roller used in the above patents rotates passively relative to the friction with the plate during movement, which will cause greater relative sliding between the surface of the aluminum plate and the pressure roller, and both friction and wear will increase, which can easily cause scratches, abrasions and other damage to the aluminum plate during the rolling and leveling process, greatly affecting the surface quality of the aluminum plate, and the contact point between the pressure roller and the aluminum plate cannot be guaranteed to change continuously. When the pressure roller does not rotate, the contact area with the aluminum plate is relatively fixed. On this fixed contact surface, the pressure is concentrated on specific parts, so that these local areas are under greater pressure, while other areas that are not in contact or are not in sufficient contact have less pressure. This uneven pressure distribution makes it impossible for the aluminum plate to obtain comprehensive and uniform plastic deformation during the rolling process, making it difficult to effectively eliminate the surface unevenness. Summary of the Invention

It is rotatably connected to an extension pipe through a rotating sealing joint, and the end of the extension pipe away from the first suction pipe is fixedly connected to a vertically arranged second suction pipe, and the lower end of the second suction pipe is fixedly connected to a second suction head with a long strip structure.

The filter assembly and the suction pump are both fixedly installed at the lower end of the lifting plate.

[0021] In the above-mentioned aluminum plate curtain wall plane correction device, the lubricant spraying mechanism includes a spray head fixedly inserted on the side wall of the fixed frame, and one end of the spray head located on the outside of the fixed frame is fixedly connected to a spray pipe, and a spray pump and a lubricant storage box are installed on the spray pipe, and the spray pump and lubricant storage box are both fixedly installed on the lifting plate.

[0022] Compared with the existing technology, the beneficial effects of the present invention are:

[0023] 1. Through the set transfer mechanism, synchronous transmission mechanism, and active cleaning and impurity removal mechanism, the surface of the aluminum plate and the rolling wheel can be thoroughly cleaned before the plane correction work of the aluminum plate curtain wall is carried out to ensure that the surface of the aluminum plate and the rolling equipment is smooth and free of foreign matter, and avoid the presence of foreign matter that may easily cause the aluminum plate to be scratched or pressed out during the rolling process. Because the hardness of the aluminum plate is low, these problems are more likely to occur.

[0024] 2. Through the set rolling correction mechanism and synchronous transmission mechanism, during the process of planar correction of the aluminum plate, the driving roller can be driven to rotate actively and cooperatively, continuously and stably applying pressure and frictional force to the aluminum plate. In this way, the aluminum plate can pass through the rolling area continuously and smoothly, ensuring uniform leveling in the entire length direction, effectively avoiding problems such as local non-leveling or inconsistent leveling effects, greatly improving the leveling efficiency and quality. At the same time, the active rotation of the rolling roller significantly reduces the relative sliding between the aluminum plate surface and the rolling roller, reduces the frictional force and wear degree, and further reduces the probability of damage such as scratches and abrasions on the aluminum plate surface, ensuring good surface quality of the aluminum plate.

[0025] 3. Through the set rolling pressure supply mechanism, rolling correction mechanism, transfer mechanism, and laser rangefinder, the rolling pressure and speed can be automatically adjusted according to the thickness of the aluminum plate to be corrected. The thicker the aluminum plate, the greater its stiffness and strength, and to cause plastic deformation to achieve the leveling purpose, a greater external force needs to be applied, so the rolling pressure is greater. At the same time, when rolling a thicker aluminum plate, more time is required to achieve uniform plastic deformation. If the rolling speed is too fast, it will not only cause uneven stress distribution inside the aluminum plate, affecting the leveling effect, but also cause equipment overload, so the rolling speed is slower.

[0026] 4. Through the set uniform pressure maintaining mechanism, a comprehensive and uniform pressing force can be applied to the entire rolling roller. Different from the prior art that only relies on the connections at both ends of the rolling roller to provide pressure, this method can effectively avoid the problem of insufficient pressure in the middle of the rolling roller and excessive pressure at both ends, making the pressure distribution on the contact surface between the rolling roller and the aluminum plate tend to an ideal state, that is, the pressure at each part is basically the same. In this way, during the rolling process of the aluminum plate, each part can be extruded to the same degree, significantly reducing the phenomenon of uneven internal stress of the aluminum plate caused by pressure differences, and further reducing the risk of deformation of the aluminum plate during subsequent processing or use.

[0027] 5. Through the set lubricant spraying mechanism and laser rangefinder, the surface of the rolling roller can be sprayed with lubricant. The lubricant can form a protective film between the aluminum plate and the roller surface, reducing the friction coefficient between the two, reducing the heat and wear generated by friction, effectively protecting the surface quality of the aluminum plate. Moreover, it can automatically adjust the spraying amount of the lubricant according to the magnitude of the rolling pressure during the planar correction of the aluminum plate. When the rolling pressure increases, the frictional force between the aluminum plate and the roller surface increases accordingly. At this time, the lubricant dosage is automatically increased to ensure the lubrication effect and avoid damage to the aluminum plate surface due to excessive friction.

The lower ends of the multiple fixed rods 41 are fixedly connected to the same fixed frame 42. The inner wall of the fixed frame 42 is rotatably connected to the roller pressure wheel 44 through the wheel shaft 43.

[0042] The uniform pressure maintaining mechanism 5 is fixedly mounted on the lower end of the roller pressure supply mechanism 3 and is in contact with the roller pressure correction mechanism 4. The uniform pressure maintaining mechanism 5 includes a plurality of connecting rods 51 fixedly connected to the lower end of the lifting plate 33. The lower ends of the plurality of connecting rods 51 are fixedly connected to the same arc-shaped extrusion plate 52. The inner side of the arc-shaped extrusion plate 52 is fixedly connected to a plurality of extrusion rollers 53 that abut against the upper end of the roller pressure wheel 44.

[0043] The synchronous transmission mechanism 6 is installed between the transfer mechanism 2 and the rolling correction mechanism 4. The synchronous transmission mechanism 6 includes a linkage shaft 61 rotatably connected to the front side of the transmission seat 24. The linkage shaft 61 and the wheel axle 43 are connected through a sprocket assembly 62. The front end of the linkage shaft 61 is also fixedly connected to a synchronous gear 63. The lower end of the horizontal part of the U-shaped support plate 21 is fixedly connected to a fixed rack 64 engaged with the synchronous gear 63.

[0044] The active cleaning and impurity removal mechanism 7 is installed between the roller pressure supply mechanism 3 and the roller pressing and correcting mechanism 4. The active cleaning and impurity removal mechanism 7 includes a first suction pipe 71 fixedly inserted into one side of the fixed frame 42. One end of the first suction pipe 71 located inside the fixed frame 42 is fixedly connected to a first suction head 72 with a long strip structure. One end of the first suction pipe 71 located outside the fixed frame 42 is rotationally connected to an extension pipe 73 through a rotary sealing joint. One end of the extension pipe 73 far from the first suction pipe 71 is fixedly connected to a second suction pipe 74 arranged vertically. The lower end of the second suction pipe 74 is fixedly connected to a second suction head 75 with a long strip structure. An electric motor rotation assembly 76 for driving the extension pipe 73 to rotate is fixedly installed on the outer wall of the fixed frame 42. The upper end of the second suction pipe 74 is fixedly connected to an elastic telescopic pipe 77. A filtering assembly 78 and a suction pump 79 are installed on the elastic telescopic pipe 77. Both the filtering assembly 78 and the suction pump 79 are fixedly installed at the lower end of the lifting plate 33.

[0045] The lubricant spraying mechanism 8 is installed between the roller pressure supply mechanism 3 and the roller pressing and correcting mechanism 4. The lubricant spraying mechanism 8 includes a spraying head 81 fixedly inserted into the side wall of the fixed frame 42. One end of the spraying head 81 located outside the fixed frame 42 is fixedly connected to a spraying pipe 82. A spraying pump 83 and a lubricant storage box 84 are installed on the spraying pipe 82. Both the spraying pump 83 and the lubricant storage box 84 are fixedly installed on the lifting plate 33.

[0046] The laser rangefinder 9 is embedded at the lower end of the roller pressing and correcting mechanism 4 and is electrically connected to the PLC controller. The PLC controller automatically regulates the use height of the active cleaning and impurity removal mechanism 7 based on the distance signal fed back by the laser rangefinder 9, and the PLC controller automatically regulates the supply pressure value of the roller pressure supply mechanism 3 and the transfer speed of the transfer mechanism 2 based on the aluminum plate thickness information fed back by the laser rangefinder 9.

[0047] Now, the operating principle of the present invention is described as follows: The aluminum plate to be flat-corrected is fixedly installed on the workbench 1 (the aluminum plate is limited and fixed by means of side clamps or vacuum adsorption). The PLC controller controls the laser rangefinder 9 to work. The laser rangefinder 9 detects the distance between it and the aluminum plate, and then makes a difference comparison with the distance value between the laser rangefinder 9 and the workbench 1, so as to confirm the thickness of the aluminum plate;

[0048] After the laser rangefinder 9 detects the distance from the aluminum plate and feeds back a signal to the PLC controller, the PLC controller controls the hydraulic push rod 32 to push the active cleaning and impurity removing mechanism 7 downward, so that a gap of 1 cm is maintained between the second suction head 75 and the aluminum plate. At this time, the PLC controller controls the forward and reverse motor 23 and the suction pump 79 to work. The suction pump 79 cooperates with the elastic telescopic tube 77 to form a negative pressure suction force in the first suction pipe 71 and the second suction pipe 74. The second suction head 75 forms a negative pressure suction force on the surface of the aluminum plate, quickly sucking the dust and impurities on the surface of the aluminum plate into the filter assembly 78. The first suction head 72 adsorbs the dust and impurities adhering to the surface of the roller 44 into the filter assembly 78. The forward and reverse motor 23 first drives the transmission screw 22 to rotate forward. Through the threaded socket connection of the transmission screw 22 and the transmission seat 24, the active cleaning and impurity removing mechanism 7 moves along the surface of the aluminum plate to comprehensively clean the surface of the aluminum plate. During the movement of the transmission seat 24, the synchronous gear 63 moves relative to the fixed rack 64, thereby driving the linkage shaft 61 to rotate. The linkage shaft 61 cooperates with the sprocket assembly 62 to drive the wheel shaft 43 to drive the roller 44 to rotate, so that the first suction head 72 can comprehensively clean the surface of the roller 44;

[0049] When the transmission seat 24 moves to the end of the U-shaped support plate 21, at this time, the PLC controller controls the forward and reverse motor 23 to reverse, driving the transmission seat 24 to move back. During this process, the PLC controller controls the active cleaning and impurity removing mechanism 7 to stop operating and starts the lubricant spraying mechanism 8 to work. The spraying pump 83 cooperates with the spraying pipe 82 to transport the lubricant in the lubricant storage box 84 into the spraying head 81, and the spraying head 81 evenly sprays the lubricant on the outside of the roller 44. And based on the aluminum plate thickness information measured and fed back by the laser rangefinder 9, the working power of the spraying pump 83 is automatically adjusted. The greater the thickness of the aluminum plate, the greater the working power of the spraying pump 83, so that more lubricant is sprayed on the surface of the roller 44 per unit time, increasing the spraying amount of the lubricant. Because the greater the thickness of the aluminum plate indicates that the rolling pressure needs to be greater. When the rolling pressure increases, the friction between the aluminum plate and the roller surface increases accordingly. At this time, the lubricant dosage is automatically increased to ensure the lubrication effect and prevent the surface of the aluminum plate from being damaged due to excessive friction;

[0050] When the transmission seat 24 moves to the end of the U-shaped support plate 21 again, it indicates that the spraying work of the lubricant is also completed. At this time, the PLC controller first controls the motor rotation assembly 76 to act (the motor rotation assembly 76 here is composed of a motor and a gear assembly, and the transmission method is a prior art, which will not be elaborated here). The motor rotation assembly 76 drives the extension pipe 73 to drive the second suction pipe 74 to turn over, so that the second suction head 75 turns over to the upper side, avoiding the obstruction of the second suction head 75 from affecting the subsequent planar correction work of the rolling wheel 44. Then the PLC controller controls the hydraulic push rod 32 to act, so that the hydraulic push rod 32 pushes the lifting plate 33 to move downward, and then the rolling wheel 44 abuts and presses on the upper end of the aluminum plate. And until the pressure signal feedback by the pressure sensing plate 34 at the connection of the hydraulic push rod 32 and the lifting plate 33 reaches the threshold value, it indicates that the correction pressure of the rolling wheel 44 meets the standard. At this time, the PLC controller controls the hydraulic push rod 32 to stop the continuous pushing action, avoiding the problem that the pressure is too small to achieve the leveling effect, and the pressure is too large will cause excessive deformation, surface damage or even rupture of the aluminum plate. And the set threshold value of the pressure sensing plate 34 is automatically adjusted based on the aluminum plate thickness information measured by the laser rangefinder 9. The greater the thickness of the aluminum plate, the greater the set threshold value of the pressure sensing plate 34, so that the rolling wheel 44 provides a greater rolling pressure. Because the thick aluminum plate has greater stiffness and strength, to make it undergo plastic deformation to achieve the leveling purpose, a greater external force is required. The forward and reverse motor 23 drives the transmission screw 22 to rotate, and through the threaded socket action of the transmission screw 22 and the transmission seat 24, the rolling wheel 44 can move on the surface of the aluminum plate to perform a comprehensive rolling work on the aluminum plate;

[0051] And when the rolling wheel 44 is under pressure, the extrusion rollers 53 in the arc-shaped pressing plate are evenly pressed on the upper end of the rolling wheel 44, thereby providing a comprehensive and uniform pressing force on the rolling wheel 44. Different from the prior art that only relies on the pressure provided at the two ends of the rolling wheel 44, this method can effectively avoid the problem of insufficient pressure in the middle and excessive pressure at both ends of the rolling wheel 44, making the pressure distribution on the contact surface between the rolling wheel 44 and the aluminum plate tend to an ideal state, that is, the pressure at each part is basically the same. In this way, during the rolling process of the aluminum plate, each part can be squeezed to the same degree, significantly reducing the phenomenon of uneven internal stress of the aluminum plate caused by pressure difference, and thus reducing the risk of deformation of the aluminum plate during subsequent processing or use;

[0052] During the movement of the transmission seat 24 driving the roller 44, in cooperation with the synchronous transmission mechanism 6, the roller 44 can rotate synchronously, continuously and stably applying pressure and frictional force to the aluminum plate. In this way, the aluminum plate can pass through the rolling area continuously and smoothly, ensuring uniform leveling in the entire length direction, effectively avoiding problems such as local non-leveling or inconsistent leveling effects, greatly improving the leveling efficiency and quality. At the same time, the active rotation of the roller 44 significantly reduces the relative sliding between the surface of the aluminum plate and the roller 44, reducing the frictional force and wear degree, and further reducing the probability of damage such as scratches and abrasions on the surface of the aluminum plate, ensuring good surface quality of the aluminum plate;

[0053] And based on the aluminum plate thickness information measured by the laser rangefinder 9, the working power of the forward and reverse motor 23 is automatically regulated. The greater the thickness of the aluminum plate, the smaller the working power of the forward and reverse motor 23, resulting in a lower rolling speed. Thicker aluminum plates require more time to achieve uniform plastic deformation during the rolling process. Therefore, the rolling speed is usually slower. If the speed is too fast, it will cause uneven stress distribution inside the aluminum plate, affecting the leveling effect and even possibly causing equipment overload.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
