Description

Technical Field

[0001] This utility model relates to the field of optical film production technology, and in particular to an explosion-proof film accelerated drying coating mechanism. Background Technology

[0002] Explosion-proof film is a special thin-film material, and it comes in various types and definitions depending on its application and specific function. Explosion-proof film is widely used in pressure vessels, automobiles, construction, and other fields to enhance the safety and protective capabilities of glass. In emergencies such as natural disasters, hurricanes, or terrorist attacks, glass explosion-proof film can provide additional protection.

[0003] The production process of explosion-proof film includes key steps such as formulation production and filtration, coating, drying, PET film lamination, slitting, and packaging. After coating, the film needs to be dried. Existing coating mechanisms cannot dry the explosion-proof film simultaneously; it must be placed in a separate drying unit after coating, resulting in long drying times and low efficiency. Therefore, a mechanism for accelerating the drying of explosion-proof film coating is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing coating mechanisms cannot dry the explosion-proof film at the same time as coating, and require the explosion-proof film to be placed in a separate drying device after coating, which results in long drying time and low work efficiency. Therefore, this invention proposes an explosion-proof film accelerated drying coating mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An explosion-proof film accelerated drying coating mechanism includes a support platform, a rectangular shell fixedly connected to the top of the support platform, a first limiting groove on the support platform, a placement plate inside the rectangular shell, a rectangular groove on the placement plate, a circular hole on the placement plate, a flattening mechanism on the placement plate, a coating mechanism inside the rectangular shell, and a sliding door hinged to the rectangular shell, with an observation window on the sliding door.

[0007] Preferably, the flattening mechanism includes a first drive motor, a bidirectional screw, a first moving block, an L-shaped plate, a first electric push rod, and a pressure plate.

[0010] The top of the rectangular shell is fixedly connected to a first rectangular plate, and the second drive motor is installed on one side of the first rectangular plate. The top of the rectangular shell has a rectangular opening, and the second electric push rod is located inside the rectangular opening.

[0011] Preferably, a rectangular box is fixedly connected to the top of the rectangular shell, a powerful pump is installed inside the rectangular box, and a suction pipe and a discharge pipe are connected to the powerful pump.

The smoothing roller smooths the coating material on the explosion-proof film. At the same time, the heat generated by the electric heating rod dries the explosion-proof film being coated through the circular hole. Coating and drying are carried out simultaneously, which requires less time and has high work efficiency.

[0029] When it is necessary to coat both sides of the explosion-proof film, after the coating in the middle part is completed and dried, the two pressure plates 12 move towards the middle to flatten it and coat both sides.
