Referring to fig. 1, the present invention provides a film covering device, which is applied to a certificate manufacturing process for covering a film on a certificate. The laminating mechanism comprises a rack 100, and a film releasing mechanism 200, a film collecting mechanism 300, a film pressing mechanism 400 and a film separating mechanism 500 which are arranged on the rack 100, wherein the film releasing mechanism 200 is used for releasing a material belt, and a film to be laminated on a certificate is attached to the material belt released from the film releasing mechanism 200; the film collecting mechanism 300 is used for collecting empty material belts; the film pressing mechanism 400 can be opened and closed, so that the film on the material belt is pressed on the certificate; after the film is laminated onto the document, the film separating mechanism 500 can separate the film from the material tape.

Referring to fig. 2, the lamination mechanism 400 includes a first lamination plate 410, a second lamination plate 420 and a first driving assembly 430, wherein the first driving assembly 430 is connected to the first lamination plate 410 and is used for driving the first lamination plate 410 to approach or depart from the second lamination plate 420. The tape passes through the first film pressing plate 410 and the second film pressing plate 420 after coming out of the film placing mechanism 200, and then enters the film collecting mechanism 300 for winding.

In this embodiment, the first lamination plate 410 is located below the second lamination plate 420, and the first driving assembly 430 is disposed below the first lamination plate 410, i.e. the lamination mode of the lamination mechanism 400 is the lower pressing.

In addition, the first driving assembly 430 is generally heavy, and the first driving assembly 430 can be arranged at a position which is lower than the laminating device by a pressing mode of lower pressing, so that the center of gravity of the laminating device is more stable, and the safety performance is improved. For convenience of description, the moving direction of the first lamination plate 410 is defined as Z-axis, and the direction indicated by the arrow in fig. 1 is a positive direction. When the first drive assembly 430 drives the first lamination plate 410 along the positive direction of the Z axis, the first lamination plate 410 moves towards the direction close to the second lamination plate 420, and when the first drive assembly 430 drives the first lamination plate 410 along the negative direction of the Z axis, the first lamination plate 410 is far away from the second lamination plate 420.
