DETAILED DESCRIPTION

[0048] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings of the preferred embodiments of the present application. In the drawings, identical or similar labels represent identical or similar components or components with identical or similar functions throughout.

The embodiments of the present application will be described in detail below with reference to the drawings.

For one of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] In the description of the embodiments of the present application, it should be understood that the terms “up”, “down”, “front”, “back”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer” and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0051] In the description of the embodiments of the present application, the meaning of “multiple” is two or more, unless otherwise specified and limited.

[0052] The terms “first”, “second”, “third”, “fourth” and the like in the specification and claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a particular order or sequence.

[0053] Furthermore, the terms "comprise", "comprising", "have", "having", "include", "including", "contain", "containing", "provide", "providing", "offer", "offering", "specify", "specifying", "preserve", "preserving" and their any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or apparatus that comprises a list of steps or units can not necessarily be limited to those steps or units which are expressly listed, but can include other not expressly listed steps or units inherent to such process, method, product or apparatus.

[0054] As the background art, the aluminum surface drawing process has become a conventional surface treatment process for high-end aluminum products, which can not only avoid the defects on the surface of the aluminum base material, but also improve the texture of the surface of the aluminum product, making the drawn aluminum product beautiful and fashionable.

[0055] In the related art, the aluminum surface drawing process is produced by a rolling mill through a rolling process on the surface of the aluminum plate, which has high production efficiency and uniform surface wire pattern. During the rolling production process of the drawn aluminum product, due to the cutting force of the rolling mill on the surface of the aluminum plate, aluminum chips will be left on the surface of the drawn aluminum product after rolling, affecting the beauty of the drawn aluminum, and the residual aluminum chips may even damage the drawn aluminum product. This is because the aluminum chips are generated by the cutting of the rolling mill on the surface of the aluminum plate. If not cleaned in time, the aluminum chips will adhere to the surface of the drawn aluminum product, directly affecting the visual beauty. When the drawn aluminum products are stacked or transported, the aluminum chips will be accumulated between adjacent drawn aluminum products, causing indentation and damaging the surface of the drawn aluminum product, affecting the product quality.

[0056] Based on the above technical problems, the embodiments of the present application provide a dedusting mechanism and a rolling mill. In the technical solution, the dedusting mechanism includes a mounting frame, a connecting assembly and a cleaning assembly. The mounting frame is used to mount the rolling mill. The connecting assembly has a fixed part and an extension part. The connecting assembly is connected with the mounting frame through the fixed part, and the extension part can be close to or away from the fixed part. The cleaning assembly is connected with the extension part of the connecting assembly. The length direction of the cleaning assembly is configured to be consistent with the length direction of the rolling mill. The cleaning assembly is configured to, under the action of the extension part, approach the rolling mill along the radial direction of the rolling mill and abut against the rolling mill to clean the rolling mill, or move away from the rolling mill.

[0057] By configuring the length direction of the cleaning assembly to be consistent with the length direction of the rolling mill, it is ensured that the cleaning assembly can clean the surface of the rolling mill along the tangent direction of the rolling mill, completely covering the working surface of the rolling mill and improving the cleaning effect. The driving force of the extension part realizes the active approach or separation of the cleaning assembly along the radial direction of the rolling mill. Compared with the static brushing device, the above-mentioned mode can make the cleaning assembly have better contact pressure with the rolling mill, and deeply strip the embedded aluminum chip particles. In addition, the variable stroke design of the extension part gives the cleaning assembly real-time adjustment capability. When the diameters of the rolling mills or the wear degrees are different, the contact pressure can be maintained by adjusting the extension amount.

[0058] It should be noted that, Figures 1 to 7The schematic diagram of the impurity removing mechanism and the schematic diagram of the parts in the rolling mill are shown, and the specific structure of the impurity removing mechanism and the rest of the parts in the rolling mill is not limited to Figures 1 to 7 .

[0059] The present application will be described in detail below with reference to the drawings and specific embodiments:

[0060] Referring to Figure 1 , Figure 2 and Figure 3 , the impurity removing mechanism provided by the embodiments of the present application is used to clean the impurities on the rolling mill 10. Specifically, the impurity removing mechanism provided by the embodiments of the present application can be used to clean the solid impurities such as aluminum scraps remaining on the surface of the rolling mill 10, and can also be used to clean the liquid impurities such as machine oil on the surface of the rolling mill 10.

[0061] The impurity removing mechanism includes a mounting frame 100, a connecting assembly 200 and a cleaning assembly 300. The mounting frame 100 is used to mount the rolling mill 10. Here, the mounting frame 100 can be understood as providing a mounting position for the rolling mill 10, or providing a support position for the rolling mill 10. The rolling mill 10 can be mounted on the rolling mill or mounted on the mounting frame 100.

[0062] The connecting assembly 200 has a fixed part 201 and an extension part 202. The connecting assembly 200 is connected to the mounting frame 100 through the fixed part 201, and the extension part 202 can be close to or away from the fixed part 201. The cleaning assembly 300 is connected to the extension part 202 of the connecting assembly 200. The length direction of the cleaning assembly 300 is configured to be consistent with the length direction of the rolling mill 10. The cleaning assembly 300 is configured to, under the action of the extension part 202, approach the rolling mill 10 along the radial direction of the rolling mill 10 and be used to abut against the rolling mill 10 to clean the rolling mill 10, or away from the rolling mill 10.

[0063] In specific implementation, the mounting frame 100 can be a rectangular frame. If necessary, the mounting frame 100 can be provided on the rolling mill, or it can be understood that the mounting frame 100 can be an integral part of the rolling mill, or the mounting frame 100 is a part of the rolling mill. In Figure 1 , the rolling mill 10 is mounted at the middle position of the mounting frame 100 in the Z direction, and in the related art, the rolling mill 10 is rotationally connected to the mounting frame 100. The way in which the rolling mill 10 is rotationally connected to the mounting frame 100 is not limited by the embodiments of the present application. The mounting frame 100 includes a top beam 110, a bottom beam 120 and two side beams 130. The top beam 110 and the bottom beam 120 are connected through the two side beams 130. The rolling mill 10 is mounted between the two side beams 130. In the Z direction, the top beam 110 is located above the bottom beam 120. The connecting assembly 200 and the cleaning assembly 300 can be provided with two, and the connecting assembly 200 and the cleaning assembly 300 correspond one by one.

[0064] One of the connecting assemblies 200 is connected with the top beam 110, and the cleaning assembly 300 connected with the connecting assembly 200 is arranged at the top of the roller 10 and used to abut against the top end of the roller 10. The other connecting assembly 200 is connected with the bottom beam 120, and the other cleaning assembly 300 arranged above the connecting assembly 200 is arranged at the bottom of the roller 10 and used to abut against the bottom end of the roller 10.

[0065] The cleaning assembly 300 arranged above the roller 10 can move downwards under the action of the telescopic part 202 of the connecting assembly 200 connected with the cleaning assembly 300 to abut against the top end of the roller 10, and the cleaning assembly 300 arranged below the roller 10 can move upwards under the action of the telescopic part 202 of the connecting assembly 200 connected with the cleaning assembly 300 to abut against the bottom end of the roller 10. In this way, by arranging two connecting assemblies 200 and two cleaning assemblies 300, the impurities on the top end and the bottom end of the roller 10 can be cleaned respectively, and the cleaning effect is improved.

[0066] In the above embodiment, by arranging the length direction of the cleaning assembly 300 to be consistent with the length direction of the roller 10, it is ensured that the cleaning assembly 300 can clean the surface of the roller 10 along the tangent direction of the roller 10, completely cover the working surface of the roller 10, and improve the cleaning effect. The driving force of the telescopic part 202 is used to realize the active approach or separation of the cleaning assembly 300 along the radial direction of the roller 10. Compared with the static brushing device, the above-mentioned mode can make the cleaning assembly 300 and the roller 10 have better contact pressure, and deeply strip the embedded aluminum particles.

[0067] In addition, the variable stroke design of the telescopic part 202 gives the cleaning assembly 300 real-time adjustment capability, and when the diameters of the rollers 10 or the wear degrees are different, the contact pressure can be maintained by adjusting the telescopic amount.

[0068] Unless otherwise specified, Figure 1 , Figure 2 and Figure 3 the X direction, the Y direction and the Z direction are perpendicular to each other in the three-dimensional space. The length direction of the roller 10 is parallel to the X direction.

[0069] In a possible implementation, please continue to refer to Figure 2 and Figure 3 , and combine Figure 4 and Figure 5As shown, the cleaning assembly 300 includes a mounting plate 310 and a scraping piece 320. The length direction of the mounting plate 310 is configured to be consistent with the length direction of the roller 10, that is, the extension direction of the mounting plate 310 is parallel to the X direction. The mounting plate 310 is provided with a fixed clamping groove 3101 on the side facing the roller 10, and the fixed clamping groove 3101 extends along the length direction of the mounting plate 310. The scraping piece 320 is connected with the mounting plate 310 and is arranged in the fixed clamping groove 3101. The scraping piece 320 is used to abut against the roller 10.

[0070] The length direction of the mounting plate 310 is configured to be consistent with the length direction of the roller 10, which ensures that the cleaning range completely covers the working face width of the roller 10 and avoids the existence of corner cleaning blind area due to size deviation. In addition, the mounting plate 310 provides full-length support for the scraping piece 320, which ensures that the scraping piece 320 stably abuts against the roller 10 in the length direction, guarantees the uniformity of the pressure of the scraping piece 320, and prevents the generation of surface color difference. The fixed clamping groove 3101 extends along the length of the mounting plate 310 to provide a continuous support track for the scraping piece 320, thereby improving the installation stability of the scraping piece 320. The scraping piece 320 is embedded in the inside of the fixed clamping groove 3101, which can convert the tangential force of the roller 10 during rotation into a forward pressure on the scraping piece 320, thereby enhancing the peeling capacity of stubborn aluminum chips and strengthening the cleaning effect.

[0071] In a possible implementation, the scraping piece 320 is bonded with the inner wall of the fixed clamping groove 3101. By adopting the bonding mode, the connection structure of the scraping piece 320 and the mounting plate 310 is simplified, and the efficiency of maintaining or replacing the scraping piece 320 is improved. In specific implementation, the scraping piece 320 is a felt. For aluminum chips, the felt has strong adsorption capacity and can improve the cleaning effect. In addition, the porous design of the felt can also absorb a large amount of liquid impurities.

[0072] In a possible implementation, the connecting assembly 200 includes a connecting piece 210 and at least two telescopic pieces 220. The connecting piece 210 is connected with the mounting rack 100, and the connecting piece 210 forms a fixed part 201 fixedly connected to the top beam 110 of the mounting rack 100.

[0073] The telescopic piece 220 is connected with the connecting piece 210, and the at least two telescopic pieces 220 are arranged at intervals along the length direction of the connecting piece 210. The movable end of the telescopic piece 220 forms a telescopic part 202, and the movable end of the telescopic piece 220 is connected with the cleaning assembly 300.

[0074] In the above embodiment, by arranging at least two telescopic members 220 and spacing along the length direction of the connecting member 210, the weight and working reaction force of the cleaning assembly 300 are dispersed to multiple support points. The load strength of a single telescopic member 220 is greatly reduced, avoiding fatigue failure caused by local overload. The symmetric or asymmetric force network formed by the spaced telescopic members 220 can effectively counteract the transverse impact moment generated during rolling, preventing the impurity removal mechanism from being skewed or shaking due to uneven force.

[0075] The plurality of telescopic members 220 significantly improves the overall bending stiffness. The cantilever structure deformation of the cleaning assembly 300 can be effectively inhibited. When there is only one telescopic member 220, for example, the telescopic member 220 is arranged at the middle position of the cleaning assembly 300 along the length direction thereof, there is only one connection point between the telescopic member 220 and the cleaning assembly 300. The structure of the cleaning assembly 300 from the above connection point to one end of the cleaning assembly 300 forms a cantilever structure of the cleaning assembly 300. If the length of the cantilever structure is relatively long, the end of the cleaning assembly 300 will be bent and deformed due to gravity and other factors. By arranging a plurality of telescopic members 220, and the plurality of telescopic members 220 are connected with the cleaning assembly 300, the plurality of telescopic members 220 can effectively disperse the gravity of the cleaning assembly 300, inhibit the deformation of the cantilever structure of the cleaning assembly 300, and further ensure the linear contact precision between the scraping member 320 and the surface of the roller 10.

[0076] In a possible implementation, the connecting member 210 includes a support plate 211 and at least two connecting legs 212 arranged on the support plate 211; the at least two connecting legs 212 are spaced along the length direction of the support plate 211, and the connecting legs 212 are connected with the mounting frame 100. Specifically, the connecting legs 212 are detachably connected with the mounting frame 100 through a plurality of bolts, facilitating later maintenance. The two connecting legs 212 are respectively connected with the two ends of the support plate 211 in the X direction, or understood as the support plate 211 and the connecting legs 212 are an integral piece. By arranging the support plate 211 and the connecting legs 212 as an integral piece, the structural strength of the connecting member 210 can be significantly improved.

[0077] The telescopic members 220 are connected with the support plate 211, and the at least two telescopic members 220 are spaced along the length direction of the support plate 211.

[0078] In the above embodiment, by arranging at least two connecting legs 212 spaced along the length direction of the support plate 211, the weight and working reaction force of the cleaning mechanism are dispersed to multiple mounting points. The load strength of a single connecting point is reduced, avoiding fatigue failure caused by local overload, and the overall bending stiffness of the connecting member 210 is significantly improved. The telescopic members 220 can be detachably fixed on the support plate 211 through flanges. The support plate 211 is provided with a relief hole, and the movable end of the telescopic member 220 can pass through the relief hole for telescopic movement.

[0079] In one possible implementation, the telescopic component 220 is a cylinder, with a connecting air pipe on the cylinder, and a pressure regulating valve and a pressure gauge on the connecting air pipe. This ensures uniform pressure on the scraper component 320 from left to right, and allows for timely adjustment of the pressure between the scraper component 320 and the surface of the roll 10. Of course, the telescopic component 220 can also be a hydraulic cylinder.

[0080] In one possible implementation, refer to Figure 3 and Figure 5 As shown, the impurity removal mechanism also includes a guide 400.

[0081] The guide member 400 is connected to the connecting assembly 200, and a guide groove 401 is provided on the guide member 400 along the extension and retraction direction of the extension and retraction part 202.

[0082] The cleaning component 300 is provided with a slider 500, which is located in the guide groove 401 so that the cleaning component 300 and the guide 400 are slidably connected.

[0083] In the above embodiment, the guide member 400 is connected to the support plate 211, and the guide member 400 is disposed at the end of the support plate 211. The extension direction of the guide groove 401 is consistent with the Z direction. The cross-section of the guide groove 401 can be rectangular, and the slider 500 is a cuboid adapted to the guide groove 401. The slider 500 is connected to the mounting plate 310. By setting the guide groove 401, the moving direction of the cleaning component 300 is further defined, providing guidance and track for the moving direction of the cleaning component 300. This allows the cleaning action to retain only the necessary one-dimensional motion, greatly improving the motion control accuracy. It also reduces the impact of lateral vibration generated during the operation of the rolling mill on the cleaning component 300. It can effectively suppress resonance phenomena and ensure continuous and stable operation.

[0084] To further improve the stability of the cleaning assembly 300, guide members 400 are provided at both ends of the support plate 211, and sliders 500 are provided at both ends of the mounting plate 310. The sliders 500 are correspondingly embedded in the guide grooves 401. This provides multi-point limiting and guiding, further improving the working stability and shock resistance of the cleaning assembly 300.

[0085] In one possible implementation, refer to Figure 5 As shown, the cross-section of the guide groove 401 can also be wedge-shaped, and the slider 500 is a wedge-shaped block, which can limit the displacement of the mounting plate 310 in the length direction and provide more shock resistance.

[0086] In one possible implementation, refer to Figure 6 and Figure 7 As shown, and in combination Figure 1The impurity removing mechanism further comprises a cooling assembly 600. The cooling assembly 600 comprises an oil storage pool 610, a circulating pump 620 and at least one oil supply pipe 630.

[0087] The oil storage pool 610 is arranged at the bottom of the roller 10, and cooling oil is arranged in the oil storage pool 610. The oil supply pipe 630 is provided with a nozzle 640, and the oil supply pipe 630 is communicated with the oil storage pool 610 and the nozzle 640.

[0088] The circulating pump 620 is configured to be communicated with the oil supply pipe 630, pump the cooling oil in the oil storage pool 610 into the nozzle 640, and make the nozzle 640 spray the cooling oil towards the roller 10. The cooling oil sprayed from the nozzle 640 flows back into the oil storage pool 610.

[0089] In the above embodiment, the oil storage pool 610 is arranged below the roller 10, and the projection of the roller 10 towards the oil storage pool 610 is located inside the oil storage pool 610, so that the cooling oil on the roller 10 can drip back into the oil storage pool 610 to complete collection, thereby realizing recycling of the cooling oil. The cooling oil can be MOA85 or MOA90 cooling oil, which can effectively lubricate the surface of the roller 10 and reduce the temperature of the roller 10 to prevent aluminum chips from cutting into the roller 10.

[0090] The oil storage pool 610 can be an open box-shaped oil storage pool 610, and the cooling oil drips into the oil storage pool 610 from the opening. The oil storage pool 610 comprises a collection area 611 and a supply area 612 which are communicated with each other. The collection area 611 is used for collecting the cooling oil dripping from the roller 10, and the supply area 612 is communicated with the oil supply pipe 630. A filter 650 is arranged between the collection area 611 and the supply area 612, or the filter 650 divides the space in the oil storage pool 610 into the collection area 611 and the supply area 612. The filter 650 comprises a metal filter screen and filter cotton. The metal filter screen is closer to the collection area 611 than the filter cotton. The cooling oil in the collection area 611 can be mixed with aluminum chips and other impurities. The cooling oil is first removed by the metal filter screen and then secondly removed by the filter cotton, so that the cooling oil in the supply area 612 is free of impurities and the oil supply pipe 630 is prevented from being blocked. The number of the metal filter screen and the filter cotton is not limited in the embodiment.

[0091] In order to guide the cooling oil in the oil storage pool 610 to flow to the supply area 612 and facilitate the oil supply pipe 630 to obtain the cooling oil, the bottom wall of the collection area 611 is arranged to be inclined towards the supply area 612. Under the action of the inclined bottom wall and the gravity, the cooling oil is accelerated to flow to the supply area 612.

[0092] The friction heat generated in the rolling process can cause the aluminum material to be locally softened or even to be melted and adhered. The cooling oil is continuously sprayed through the nozzle 640 to quickly take away the heat and control the surface temperature of the roller 10 within a reasonable range. The working area temperature of the roller 10 can be reduced to avoid the silk grain blur or surface oxidation spots caused by overheating.

[0093] Meanwhile, the cooling oil can quickly separate the aluminum scraps from the roller 10 in cooperation with the scraping effect of the scraping member 320, thereby improving the cleaning effect.

[0094] In a possible implementation, the oil delivery pipe 630 includes a spraying section 631 and a connecting section 632 that are in communication with each other. The spraying section 631 is connected to the oil storage pool 610 through the connecting section 632, and the nozzle 640 is arranged on the spraying section 631.

[0095] The extension direction of the spraying section 631 is configured to be consistent with the length direction of the roller 10, and the number of the nozzles 640 is set to be multiple. The multiple nozzles 640 are arranged at intervals along the extension direction of the spraying section 631.

[0096] The extension direction of the spraying section 631 is consistent with the length direction of the roller 10, which ensures that the spraying range of the cooling oil completely covers the working face width of the roller 10 and guarantees the uniformity of the temperature of the whole face. The multiple nozzles 640 are arranged at intervals along the spraying section 631 to form a matrix cooling network, thereby improving the cooling effect. The oil delivery pipe 630 is divided into the spraying section 631 and the connecting section 632. The fluid turbulent loss is reduced through the pipe diameter gradual change design. The connecting section 632 is used as a main delivery pipeline and adopts a large-diameter pipeline to reduce the resistance along the pipeline. The spraying section 631 adopts a small-diameter branch pipe to improve the end spraying pressure.

[0097] In specific implementation, the connecting section 632 has an oil inlet and at least two oil outlets. The oil inlet is in communication with the oil storage pool 610, and the oil outlets are in communication with the spraying section 631. By setting at least two oil outlets, the number of the spraying sections 631 can be adaptively increased, and each roller 10 can be cooled, or the aluminum plate 20 and the roller 10 can be cooled respectively, for example Figure 6 as shown in the figure. The nozzles 640 on one of the spraying sections 631 spray the cooling oil towards the aluminum plate 20 between the two rollers 10, and the nozzles 640 on the other spraying section 631 spray the cooling oil towards one of the rollers 10. The spraying section 631 is located below the roller 10 to prevent the aluminum plate 20 from injuring the nozzles 640.

[0098] Further, the spraying pressure of the nozzles 640 is controlled within 0.05 MP, for example, set to 0.03 MP, 0.04 MP, or 0.05 MP. The deformation of the aluminum plate 20 is prevented, and the flow of each nozzle 640 is controlled to be 0.2-0.5 liters per minute, and the number of nozzles 640 on each spraying section 631 is set to be 8-12. The oil delivery pipe 630 can be fixed on the mounting rack 100 or fixed by other mounting mechanisms, and the mounting mechanism of the oil delivery pipe 630 is not limited in the application.

[0099] The application further provides a rolling mill comprising a rolling mill body and the impurity removal mechanism as described above. The rolling mill body is provided with a rolling roller 10, and the rolling mill body is connected with the impurity removal mechanism, wherein the impurity removal mechanism has been described in detail above, and will not be described herein. The rolling mill has the technical effects of the impurity removal mechanism described above, solves the problem of aluminum scraps in the production process of the drawn aluminum product, and improves the quality of the drawn aluminum product.

[0100] The implementation principle of the embodiment of the application is that the impurity removal mechanism comprises a mounting rack 100, a connecting assembly 200, and a cleaning assembly 300. The mounting rack 100 is used for mounting the rolling roller 10. The connecting assembly 200 has a fixed part 201 and an extension part 202. The connecting assembly 200 is connected with the mounting rack 100 through the fixed part 201, and the extension part 202 can be close to or away from the fixed part 201. The cleaning assembly 300 is connected with the extension part 202 of the connecting assembly 200, and the length direction of the cleaning assembly 300 is configured to be consistent with the length direction of the rolling roller 10. The cleaning assembly 300 is configured to, under the action of the extension part 202, approach the rolling roller 10 along the radial direction of the rolling roller 10 and abut against the rolling roller 10 to clean the rolling roller 10, or move away from the rolling roller 10. By configuring the length direction of the cleaning assembly 300 to be consistent with the length direction of the rolling roller 10, it is ensured that the cleaning assembly 300 can clean the surface of the rolling roller 10 along the tangent direction of the rolling roller 10, completely cover the working surface of the rolling roller 10, and improve the cleaning effect. The driving force of the extension part 202 realizes the active approach or separation of the cleaning assembly 300 along the radial direction of the rolling roller 10. Compared with the static brushing device, the above-mentioned mode can make the cleaning assembly 300 have better contact pressure with the rolling roller 10, and deeply strip the embedded aluminum scrap particles. In addition, the variable stroke design of the extension part 202 gives the cleaning assembly 300 real-time adjustment capability. When the diameters of the rolling rollers 10 or the wear degrees are different, the contact pressure can be maintained by adjusting the extension amount.
