Film rolling device for intelligent blackboard display screen and working method of film rolling device

Abstract

The invention relates to a film rolling device for an intelligent blackboard display screen. The film rolling device for the intelligent blackboard display screen comprises a rack, a lifting base and a limiting base, supporting columns are fixedly installed on the two sides of the top of the rack, a top frame is installed on the top sides of the supporting columns, an air pressure rod is vertically installed on the bottom side of the top of the top frame, the telescopic end of the air pressure rod is connected with the lifting base on the outer side of the top frame, a connecting base is installed on the outer side of the lifting base, an installing base is installed on the bottom side of the connecting base, a sliding base is installed on the top side of the rack in a sliding mode, the limiting base used for fixing the display screen is installed on the top side of the sliding base, and a rolling mechanism is installed on the bottom side of the installing base. Meanwhile, during rolling, an inflated rolling air bag deforms in real time and is always tightly attached to the display screen, film rolling operation on display screens with different curvatures is achieved through deformation of the rolling air bag during rolling, and when foreign matter exists on the display screens, the foreign matter is directly embedded into the rolling air bag in the rolling process, and direct influence on contact between foreign matters and a rolling part as well as between the foreign matters and the display screens is avoided.

Description

technical field [0001] The invention relates to the technical field of smart blackboard processing, in particular to a film rolling device for a smart blackboard display and a working method thereof. Background technique [0002] The smart blackboard integrates traditional blackboard, large-screen display, screen touch control, OPS computer, audio, high-speed camera, Internet of Things and other related equipment. It can not only realize all the functions of an interactive machine, but also use traditional chalk on the entire board. to write. At the same time, it is embedded with smart classroom teaching software, one-key recording and broadcasting and artificial intelligence system. It can realize all the functions of the future classroom by connecting a network cable and a power cord. It is the core equipment of the future classroom; the display screen of the smart blackboard is attached with a A protective film with a protective effect. [0003] After the protective fil...

Problems solved by technology

[0004] The problem to be solved by the present invention is to provide a film rolling device and its working method for the display screen of a smart blackboard, which solves the problem of removing the protective film by rolling back and forth on the display screen with a pressure roller after the protective film is attached to the existing smart blackboard. The air between the film and the display screen ensures that the protective film and the display screen are tightly bonded. The pressure roller is in hard contact with the protective film during the back and forth rolling process, which is easy to cause damage to the display screen during rolling. Once there are foreign objects in the rolling process Falling on the protective film, foreign matter may easily cause scratches on the protective film and the display screen during rolling; at the same time, the existing rolling device is only used for the rolling process of the flat display screen, which cannot realize the display of different specifications and different curvatures Technical Problems of Screen Film Rolling Operation
