Description

Technical Field

[0001] This utility model relates to an adaptive adjustment system for rolling force of cold-rolled aluminum foil with black wire defects on the surface. Background Technology

[0002] With the widespread application of aluminum foil in electronics, packaging, new energy and other fields, the requirements for the surface quality of aluminum foil are becoming increasingly stringent. During the production process of cold-rolled aluminum foil, due to the influence of rolling technology, equipment and materials, black streaks often appear on the surface, which seriously affects the performance and appearance quality of the aluminum foil.

[0003] Currently, in the cold rolling production of aluminum foil, horizontally placed work rolls and support rolls are commonly used to transport the aluminum foil from bottom to top. Rolling oil is sprayed onto the work rolls through an ion spraying box to reduce the accumulation of rolling oil on the aluminum foil surface and improve the rolling quality of the aluminum foil. Most existing rolling systems use a fixed-angle roll arrangement. Although this method is the most efficient, it is prone to producing regular strip-shaped gaps, i.e., black thread defects.

[0004] Therefore, there is an urgent need to develop an adaptive rolling force adjustment system that can solve the problem of black thread defects on the surface of cold-rolled aluminum foil, so as to effectively reduce the generation of black thread defects on the surface of aluminum foil. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an adaptive adjustment system for rolling force to address black thread defects on the surface of cold-rolled aluminum foil. This system effectively reduces the generation of black thread defects on the aluminum foil surface and improves product quality. This purpose is achieved as follows:

[0006] This utility model proposes an adaptive adjustment system for rolling force of black wire defects on the surface of cold-rolled aluminum foil, including a main body assembly. The main body assembly includes a conveyor plate. Two roll assemblies are symmetrically arranged on the upper side of the conveyor plate. Two intermediate rolls are symmetrically arranged between the roll assemblies. The axis of one intermediate roll is inclined at an angle to the extension direction of the conveyor plate, and the axis of the other intermediate roll is also inclined at an angle to the extension direction of the conveyor plate. An oil spraying assembly and a comb plate assembly are arranged between adjacent roll assemblies and intermediate rolls, and between adjacent intermediate rolls.

[0007] Furthermore, it also includes an oil reservoir. The oil injection components are all connected to the oil injection assembly via pipes. The oil injection assembly is connected to the main body assembly via bolts. The oil reservoir is also equipped with a pump for pumping lubricating fluid.

[0008] Furthermore, the oil injection assembly includes a plurality of nozzles arranged laterally at equal intervals for spraying lubricating fluid.

[0009] Furthermore, the comb plate assembly is bolted to the main body assembly, and the comb plate assembly includes preset comb bristles corresponding to the conveyor plate for uniformly applying lubricant.

[0010] Furthermore, the inclination angle between the axis of the intermediate roll and the extension direction of the conveyor plate is 30 degrees, and the two intermediate rolls are mirror images of each other.

[0011] Furthermore, the intermediate roll is fixed to the main body assembly by a pre-set mounting platform and bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by using two inclined intermediate rollers, a force different from the extension direction of the conveyor belt is applied to the aluminum foil. Through the opposite friction, the transverse cracks on the surface of the aluminum foil can be effectively smoothed, thereby reducing the generation of black thread defects. Since the axis of the intermediate roller has a 30-degree inclination angle with the extension direction of the conveyor plate, and the two intermediate rollers are set in mirror image, the aluminum foil is subjected to uniform pressure in multiple directions when passing through, which effectively eliminates the surface micro-defects, and the structure is simple.

[0016] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0017] Please refer to Figure 1-2This utility model proposes an adaptive adjustment system for rolling force of cold-rolled aluminum foil with black wire defects on the surface. The system includes a main body assembly 6, which includes a conveyor plate 7. Two roll assemblies 1 are symmetrically arranged on the upper side of the conveyor plate 7, and two intermediate rolls 5 are symmetrically arranged between the roll assemblies 1. The axis of one intermediate roll 5 is inclined at an angle to the extension direction of the conveyor plate 7, and the axis of the other intermediate roll 5 is also inclined at an angle to the extension direction of the conveyor plate 7. The inclination angle between the axes of the two intermediate rolls 5 and the extension direction of the conveyor plate 7 is 30 degrees. A mirror is positioned between the two intermediate rolls 5. This design ensures that the aluminum foil experiences uniform pressure distribution during passage, effectively reducing the formation of black thread defects. The intermediate roll 5 is fixed to the main body assembly 6 via a pre-set mounting platform and bolts, ensuring that the intermediate roll 5 maintains stability during operation and does not cause uneven rolling force due to vibration. An oil spraying assembly 2 and a comb plate assembly 4 are arranged between adjacent roll assemblies 1 and intermediate roll 5, and an oil spraying assembly 2 and a comb plate assembly 4 are also arranged between adjacent intermediate rolls 5. This layout design allows the lubricant to be evenly distributed on the aluminum foil surface, reducing friction and preventing the formation of black thread defects.

[0018] The system also includes an oil storage tank 3. The oil spraying components 2 are all connected to the oil storage tank 3 through pipes. The oil spraying components 2 are connected to the main body component 6 by bolts. A pump is also installed on the oil storage tank 3 to pump the lubricant. The pump delivers the lubricant in the oil storage tank 3 to each oil spraying component 2 through pipes to ensure a stable and sufficient supply of lubricant, thereby ensuring the continuity and stability of the rolling process. The oil spraying component 2 includes several nozzles, which are arranged laterally at equal intervals for spraying lubricant. The equidistant distribution design of these nozzles ensures that the lubricant can be evenly covered on the aluminum foil surface, avoiding the increase of local friction caused by uneven lubrication, and thus reducing the probability of black thread defects. The comb plate component 4 is installed on the main body component 6 by bolts. The comb plate component 4 includes preset combs corresponding to the conveyor plate 7 for evenly applying lubricant. The comb design allows the lubricant sprayed onto the aluminum foil surface to be more evenly distributed, further improving the lubrication effect and reducing black thread defects caused by uneven lubrication.

[0019] During system operation, aluminum foil is conveyed by conveyor plate 7 and pressed by roll assembly 1 and intermediate roll 5. At the same time, oil spraying assembly 2 sprays lubricant onto the surface of aluminum foil, and comb plate assembly 4 evenly applies the lubricant. Since the axis of intermediate roll 5 has a 30-degree tilt angle with the extension direction of conveyor plate 7, and the two intermediate rolls 5 are set in mirror image, the aluminum foil is subjected to frictional force tangential to the extension direction of conveyor plate 7 during the rolling process. The frictional force is made more controllable by artificially increasing the frictional force, effectively grinding the surface of aluminum foil. Furthermore, the two intermediate rolls 5 at different angles further reduce the generation of regular gaps.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
