Description
Technical Field
[0001] This utility model belongs to the field of aluminum coil processing technology, and in particular relates to a grinding box before hot rolling of aluminum coils. Background Technology
[0002] When aluminum materials are processed, especially before the hot rolling process, it is necessary to remove and polish the oxide scale, dust and other impurities attached to the surface.
[0003] Existing traditional grinding equipment mainly focuses on removing surface burrs and concentrates on the grinding function itself. It does not consider the overall surface quality requirements of aluminum coils before hot rolling. For example, there is a lack of pretreatment before grinding and a lack of cleaning function after grinding. As a result, the dust left over from the grinding process can easily adhere to the surface of the aluminum coil, leading to defects after hot rolling. Utility Model Content
[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:
[0005] This utility model provides a grinding box for hot rolling of aluminum coils, comprising:
[0006] The aluminum coil passes through the polishing box and is continuously conveyed.
[0007] The guide platform group is symmetrically arranged on the inner sidewalls of the grinding box, corresponding to the entry and exit positions of the aluminum coil respectively.
[0008] The guide platform assembly includes two symmetrically arranged platform sections, one above the other. Each platform section has a guide block detachably mounted on one end close to the other. Each guide block includes an auxiliary component, which is mounted on one end close to the other.
[0009] The aluminum coil passes between the auxiliary components and its two end faces are in contact with the auxiliary components on the sides they are on;
[0010] The auxiliary component located at the aluminum coil entry end is a pre-grinding component, and the auxiliary component located at the aluminum coil exit end is a cleaning component.
[0011] As a preferred embodiment of the above technical solution, the platform portion of the guide platform assembly is provided with a snap-fit groove, and the guide block is movably inserted into the snap-fit groove.
[0012] As a preferred embodiment of the above technical solution, the guide block further includes a base, and the auxiliary component is disposed on the base near one end of the aluminum coil. The ends of the base and the auxiliary component that are close to each other are respectively provided with a hook and loop fastener and a rough hook and loop fastener, and the hook and loop fastener are detachably bonded together.
[0013] As a preferred embodiment of the above technical solution, a grinding roller assembly is rotatably arranged inside the grinding box, and the grinding roller assembly includes grinding roller bodies arranged symmetrically at the top and bottom.
[0014] As a preferred embodiment of the above technical solution, each end of the guide platform group near the grinding roller group is provided with a guide roller group, and the aluminum coil passes through the guide roller bodies of the guide roller group.
[0015] As a preferred embodiment of the above technical solution, a dust collector is also included. The dust collector has a dust collection pipe at its suction end, and the other end of the dust collection pipe is inserted into the grinding chamber and has a suction port at its end. The suction port is located near the grinding roller assembly.
[0016] The beneficial effects of this utility model are as follows:
[0017] This invention utilizes a guide platform assembly to pre-polish the aluminum coil before grinding, effectively removing oxide scale, dust, and other impurities from the surface, thus providing a good foundation for subsequent fine grinding. A cleaning assembly is then installed after grinding to remove residual dust and debris, preventing them from adhering to the aluminum coil surface and reducing defects such as spots, cracks, and peeling after hot rolling. This significantly improves the product's appearance quality and mechanical properties. The multi-stage collaborative processing method achieves higher flatness and cleanliness on the aluminum coil surface, meeting the requirements of aluminum processing. Attached Figure Description

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0024] Example
[0025] like Figure 1 , Figure 2 , Figure 4 As shown, Figure 1 The diagram shown is a cross-sectional view of the grinding box in the embodiment; Figure 2 The diagram shown is a schematic of the guide platform assembly in the embodiment; Figure 4 The diagram shown is a schematic of the guide block in the embodiment.
[0026] This device includes:
[0027] Aluminum coil 1 passes through and is continuously conveyed through the grinding box 10;
[0028] Guide platform group 20, the guide platform group 20 is symmetrically arranged on the inner side wall of the grinding box 10, corresponding to the entry end and exit end of the aluminum coil 1 respectively;
[0029] The guide platform group 20 includes platform parts 30 arranged symmetrically at the top and bottom. Each of the platform parts 30 has a guide block 40 detachably provided at one end close to the other. The guide block 40 includes an auxiliary component 42, which is provided at one end close to the other.
[0030] The aluminum coil 1 passes through the auxiliary components 42 and both its end faces are in contact with the auxiliary components 42 on the side where it is located;
[0031] The auxiliary component 42 located at the inlet end of the aluminum coil 1 is a pre-polishing component, and the auxiliary component 42 located at the outlet end of the aluminum coil 1 is a cleaning component.
[0032] In one embodiment, Figure 1 The direction indicated by the middle arrow A is the conveying direction of aluminum coil 1, that is, the inlet end of aluminum coil 1 is on the right and the outlet end is on the left.
[0033] The grinding box 10 is a space used to accommodate the entire grinding process. In fact, the grinding box 10 is equipped with an openable door. The aluminum coil 1 passes through the grinding box 10 and is continuously conveyed forward to form a continuous production process.
[0034] A channel is formed between the upper and lower platform sections 30 of the guide platform assembly 20 for the aluminum coil 1 to pass through. A detachable guide block 40 is installed at one end of the platform section 30 that is close to each other, which is convenient for replacement or maintenance. The guide block 40 is provided with auxiliary parts 42. The aluminum coil 1 passes through these auxiliary parts 42 and its two sides contact the corresponding auxiliary parts 42. This design can ensure that the coil remains stable during operation while also achieving effective treatment of its surface.
[0035] The auxiliary component 42 located at the entry end is a pre-grinding component. The pre-grinding component performs preliminary treatment before the aluminum coil 1 enters the formal grinding area to remove large impurities or slight unevenness on the surface. Specifically, the pre-grinding component can be sandpaper.
[0036] The auxiliary component 42 located at the exit end is a cleaning component. The cleaning component cleans the surface of the already polished aluminum coil 1, removes polishing residue, and ensures the quality of subsequent hot rolling. Specifically, the pre-polishing component can be a cleaning cloth.
[0037] like Figure 1 As shown, Figure 1 The diagram shown is a cross-sectional view of the grinding box in the embodiment;
[0038] The grinding box 10 is equipped with a grinding roller assembly 50, which includes grinding roller bodies arranged symmetrically at the top and bottom.
[0039] The grinding roller assembly 50 rotates under the drive of a power device (such as an electric motor) in the prior art, and achieves the grinding effect through the friction between it and the surface of the aluminum coil 1.
[0040] Each end of the guide platform group 20 near the grinding roller group 50 is provided with a guide roller group 60, and the aluminum coil 1 passes through the guide rollers of the guide roller group 60.
[0041] The aluminum coil 1 passes between the guide rollers of the guide roller group 60, thereby further guiding and limiting its running direction.
[0042] like Figure 3 , Figure 4 As shown, Figure 3 The diagram shown is a schematic representation of the platform section in the embodiment; Figure 4 The diagram shown is a schematic representation of the guide block in the embodiment;
[0043] The platform section 30 of the guide platform assembly 20 is provided with a snap-fit groove 31, and the guide block 40 is movably inserted into the snap-fit groove 31.
[0044] The snap-fit groove 31 is used to accommodate the guide block 40 and provide positioning and support. The two are movably inserted and matched, so that the guide block 40 can be inserted or pulled out along the direction of the snap-fit groove 31, which facilitates quick installation or replacement.
[0045] The guide block 40 also includes a base 41, and an auxiliary component 42 is disposed on the base 41 near one end of the aluminum coil 1. The ends of the base 41 and the auxiliary component 42 that are close to each other are respectively provided with a hook and loop fastener 411 and a loop and loop fastener 422, and the hook and loop fastener 411 and the loop and loop fastener 422 are detachably bonded together.
[0046] The base 41 and the auxiliary part 42 are bonded together to achieve a detachable connection. When the auxiliary part 42 needs to be replaced, the old auxiliary part 42 can be quickly removed, and a new auxiliary part 42 (such as coarser sandpaper, cleaning cloth, etc.) can be installed. Finally, it can be re-bonded to the base 41.
[0047] like Figure 1 As shown, Figure 1 The diagram shown is a cross-sectional view of the grinding box in the embodiment;
[0048] It also includes a dust collector 70, which has a dust collection pipe 71 at the dust collection end. The other end of the dust collection pipe 71 is inserted into the grinding box 10 and has a dust collection port 72 at the end. The dust collection port 72 is located near the grinding roller group 50.
[0049] The dust collector 70 works in conjunction with the dust collection pipe 71 and the suction port 72, and uses negative pressure suction to promptly remove dust, debris, and other pollutants generated during the grinding process from the grinding area inside the grinding chamber 10.
[0050] Working principle: The aluminum coil 1 is continuously fed into the grinding box 10 from one end. The aluminum coil 1 first enters the guide platform group 20 at the inlet end, where it undergoes preliminary treatment by the auxiliary component 42. The auxiliary component 42 uses materials such as sandpaper and abrasive cloth to remove large particles of impurities or oxide layers from the surface of the aluminum coil 1. The aluminum coil 1 continues to move forward, passing through the guide roller group 60 and entering the grinding roller group 50 area. The upper and lower grinding rollers rotate synchronously, performing efficient and uniform fine grinding on the aluminum coil 1. The dust generated during the grinding process is sucked into the dust inlet. 72 is immediately removed. The dust collector 70 continuously provides negative pressure suction through the dust collection pipe 71. The dust is transported through the dust collection pipe 71 to the inside of the dust collector 70 for filtration and treatment. Clean air is discharged. After the aluminum coil 1 leaves the grinding area, it enters the guide platform group 20 at the outlet end. The auxiliary parts 42 here are cleaning parts, such as brushes and lint-free cloths, to clean the surface of the ground aluminum coil 1, remove residual debris, and ensure that the surface is clean. The cleaned aluminum coil 1 is stably output from the other end of the grinding box 10 and enters the subsequent hot rolling process.
[0051] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
