Metal plate composite protective film

Abstract

The utility model relates to a composite protective film for a metal plate, which comprises a composite protective film roll I and a composite protective film roll II, protective films in the composite protective film roll I and the composite protective film roll II have the same length, the inner sides of the film rolls are provided with film rolling cylinders, the outer side surfaces of the film rolls are release films, and a fixed adhesive tape is arranged between the two film rolls. Due to the fact that the first composite protective film roll and the second composite protective film roll are arranged, fixing adhesive tape is removed in use, the metal plate can be placed on matched equipment to be directly used, films can be pasted on the two faces of the metal plate at the same time, and work efficiency is greatly improved.

Description

Technical Field

[0001] This utility model relates to the field of protective film technology, and in particular to a metal plate composite protective film. Background Technology

[0002] Metal sheet composite protective films have wide applications in various fields such as construction, automotive, home appliances, and electronic equipment. These films prevent metal sheets from being scratched, corroded, or damaged in other ways during processing, transportation, or use. They provide an additional corrosion-resistant layer, especially in harsh or chemically corrosive environments, extending the service life of the metal sheet and reducing surface wear while maintaining its gloss and integrity. Composite protective films also reduce the environmental impact of metal sheets during use. By providing an additional protective layer, composite protective films help extend the overall service life of metal sheets. Currently, metal protective film application mainly involves applying the film to the entire sheet, often double-sided. Traditional application methods involve applying the film to each side separately, resulting in low work efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems by providing a composite protective film for metal plates. It allows for simultaneous application of protective film to both sides of a metal plate, resulting in high work efficiency.

[0004] The technical solution adopted by this utility model is: a metal plate composite protective film, including a composite protective film roll one and a composite protective film roll two. The protective film in the composite protective film roll one and the composite protective film roll two has the same length. A film rolling tube is provided on the inner side of the film roll, and a release film is provided on the outer side of the film roll. A fixing tape is provided between the two film rolls.

[0005] The beneficial effects of this utility model are as follows: Because this utility model is equipped with composite protective film roll one and composite protective film roll two, it can be used directly on the matching equipment after removing the fixing tape. It can apply film to both sides of the metal plate at the same time, which greatly improves work efficiency. Attached Figure Description

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] like Figure 1 and Figure 2 As shown, this utility model includes: a composite protective film roll 1 and a composite protective film roll 2. The protective films in the composite protective film roll 1 and the composite protective film roll 2 are of the same length, which facilitates the simultaneous application of the protective film and prevents some films from only being applied to one side. The inner side of the film roll is provided with a film roll tube 11 and a film roll tube 21 for winding the protective film. The outer side of the film roll is a release film, which is located on the outside to facilitate the cutting of the release film and the connection with the winding roller. A fixing tape 3 is provided between the two film rolls to prevent the film rolls from loosening.

[0012] like Figure 3 and Figure 4 As shown, the metal plate composite protective film of this utility model is used in conjunction with the film coating equipment 4. The film coating equipment 4 includes a base plate 45, a film roll 42, a film roll 44, a film coating roller 41, a film coating roller 43, a take-up roller 48, a take-up roller 46, and a roller shaft connecting seat 49. The film coating rollers 41 and 43 are driven by a motor to roll at a uniform speed. The film roll 41 and 43 are connected to the roller shaft connecting seat through two rolling bearings. The film roll is equipped with a resistance device, i.e., there is friction from abrasive pads to prevent the film roll from being too loosely wound. The width of the roller shaft connecting seat is between 10-20 cm, and the distance between the two bearings of each roll or roller is large, which makes the connection more stable. When using the product, first remove the fixing tape 3, insert the composite protective film roll 1 into the film roll shaft 42 of the laminating equipment, and insert the composite protective film roll 2 into the film roll shaft 44 of the laminating equipment. Then, cut the release film on the outside of the composite protective film roll into two parts. Fix the end of the release film of the upper part to the take-up roller 48 with adhesive tape, and fix the end of the release film of the lower part to the take-up roller 46 with adhesive tape. Push the metal plate 5 to be coated forward. The metal plate can be pushed manually or by mechanical transmission belt, so that the composite film enters between the two coating rollers for rolling. The metal plates are continuously fed into the coating rollers one after another until the film roll is used up. Then replace it with a spare composite protective film roll and repeat the process. The working efficiency is greatly improved compared to the original product.
