Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum foil production, and particularly relates to a ground system for a clean area of ​​an aluminum foil plant. Background Art

[0002] Aluminum foil with a thickness of less than 0.2 mm is usually called aluminum foil. The thickness of aluminum foil ranges from 0.005 mm to 0.2 mm. It is widely used in various fields such as food, medicine and electronics because of its excellent light-shielding, moisture-proof, good gas barrier and taste-retaining properties. The existing production methods of aluminum foil include: rough rolling, medium rolling, coiling, tempering, fine rolling, slitting, fine cutting and packaging. If the fine cutting area and packaging area are clean workshops, then the fine cutting area and packaging area are clean areas. The clean area has requirements for the ground system, usually epoxy flooring, but for aluminum foil production, aluminum foil is usually transported in rolls, and aluminum coils need to be transported by AGV carts and other transportation tools. Both AGV carts and aluminum coils are heavy, so the AGV carts for transporting aluminum coils are heavier. Then the epoxy floor is easily scratched, and the powder after scratching will float. The clean area of ​​the aluminum foil plant is usually located in the final process. At this time, the aluminum foil is very thin (such as 0.006-0.007 mm thick) and is particularly sensitive to powder. Even a small amount of powder will affect the quality of the aluminum foil.

[0003] The applicant is considering using stainless steel plates as the floor of the clean area.

[0004] For example, the patent with application number CN202021818010.3 discloses a new dust-proof stainless steel plate floor, including a base layer, an adhesive layer and a stainless steel plate layer, the base layer is a concrete base layer, a stainless steel plate layer is laid on the base layer, and an adhesive layer is arranged between the stainless steel plate layer and the base layer; corresponding bolt holes are reserved on the base layer and the stainless steel plate layer, and the bolt holes are used to install expansion bolts, and the expansion bolts are used to connect and fix the stainless steel plate layer and the base layer; an installation groove is provided on the upper surface of the bolt hole on the stainless steel plate, and the expansion bolt is a countersunk expansion bolt. After the expansion bolt is installed, the upper surface of the expansion bolt is flush with the upper surface of the stainless steel plate.

[0005] For example, the patent with application number CN201920692979.1 discloses a stainless steel plate ground structure for bearing a large load, wherein the ground structure includes a receiving bottom layer and a stainless steel floor arranged on the upper part of the receiving bottom layer, wherein the receiving bottom layer includes a base layer, a concrete cushion layer arranged on the base layer, and a cement self-leveling layer laid on the concrete cushion layer; the stainless steel floor includes a plurality of unit stainless steel plates, and adjacent unit stainless steel plates are bite-connected; the stainless steel floor is fixed to the receiving bottom layer by bolts.
