Description

Technical Field

[0001] The utility model relates to the technical field of vacuum aluminum coating, in particular to a static electricity removal device for aluminum coating processing. Background Art

[0002] Vacuum aluminum-plated film is a type of vacuum-evaporated metal film. It is a process in which aluminum is melted and vaporized under high vacuum (above 10mba) conditions by heating with resistance, high frequency or electron beam, and adheres to the surface of the film substrate to form a composite film. A very thin layer of metal aluminum is plated on the surface of plastic film or paper to form an aluminized film or aluminized paper.

[0003] In order to improve the quality of coating, it is usually necessary to remove dust and static electricity from the substrate before coating. There are many public technologies on the market that have been mentioned. For example, there is a public technology that discloses a static removal device for vacuum aluminum-coated film processing. The key points of its technical solution include a bottom box, and the four corners of the bottom of the bottom box are fixedly connected to support legs, and a top plate is arranged above the bottom box. The top plate and the bottom box are both provided with static removal mechanisms, which aims to solve the problem that some existing static removal devices for vacuum aluminum-coated film processing are inconvenient to transport the vacuum aluminum-coated film during use, and the static electricity and dust on the vacuum aluminum-coated film are not effectively removed during the production and processing process, thereby affecting the processing quality. There is also a technology that discloses a static removal device for aluminum-coated film processing, which is used to solve the problem of residual debris on the side of the aluminum-coated film away from the fan. The technology comprises a film body, a mounting plate and an ion fan. The technology is achieved by The middle shell is installed at the lower part of the membrane body, and the ion fan can remove static electricity and dust from the surface of the membrane body while rotating, and the circumferential distribution of the ion fan can improve the device's ability to remove static electricity from the membrane body, so as to be suitable for membranes of different widths, so that the ion fan can be close to the side of the membrane body for cleaning and static removal, and there is also a technology that provides a static electricity removal device for vacuum aluminum-plated film processing, including: a support frame, a conveying member is arranged on the surface of the support frame, and a power component includes a servo motor, a rotating rod, a rotating block and a moving frame. The technology provides a static electricity removal device for vacuum aluminum-plated film processing, and the sliding component is driven to move to one side by the power component rotating to one side, and the dust collection component is driven to move to one side at the same time, so as to remove dust and static electricity from the surface of the vacuum aluminum-plated film, and at the same time, the dust blown away is sucked away and stored, so as to prevent the dust from floating in the air;

[0004] The above-mentioned disclosed technologies all transport the substrate by means of a conveyor belt, and perform static electricity and dust removal during the transportation process. Obviously, the side of the substrate facing the conveyor belt cannot be blown by the ion fan, i.e., static electricity and dust cannot be removed. Moreover, the above-mentioned disclosed technologies all remove dust and static electricity in an open environment, and the wind blown by the ion fan dissipates everywhere, resulting in a general static electricity removal effect for multiple substrates. Although one disclosed technology proposes the concept of dust collection, since it is in an open state when blowing, the dust on the substrate will not be concentrated at the dust collection port after being blown up by the wind, resulting in a limited dust collection effect. In summary, it is necessary to improve and optimize the structure of static electricity removal devices for aluminum film processing. Utility Model Content

[0030] like Figure 1 , Figure 2 As shown, in order to facilitate the adjustment of the suction angle of the dust suction port 11, the inner wall of the bellows 2 and near the left end are distributed up and down and are rotatably connected in sequence. A group of rotating seats 6 are fixedly connected to the front wall of the bellows 2 and the two groups of rotating seats 6 at the front and rear opposite positions.

The two groups of ion fans are arranged one above and one below. The accordion cover 18 maintains a seal between the mounting frame 17 and the air inlet window 13, so that the ion fan can continuously inhale air from the outside through the air inlet window 13, reducing the impact of airflow on the winding mechanism when winding. When the ion fan is working, external air is inhaled through the air inlet window 13, and the air is filtered through the filter 14 while inhaling. The negative pressure pump generates negative pressure inside the dust hood 10 and the dust suction port 11 through the dust suction pipe 12. The adsorption angle of the dust suction port 11 can be adjusted by rotating the rotating rod 7.
