technical field

The utility model relates to the technical field of sheet metal processing, in particular to a film sticking device for sheet maintenance.

Background technique

After the sheet is drawn, sanded or sprayed, it is usually necessary to stick a film on the surface of the sheet to protect the surface of the sheet. Since the current spraying or ion plating adopts an indirect production method, continuous film connection cannot be achieved, so the sheet is generally used. The film is applied manually. The existing manual filming is that the workers apply the surface filming to the sheets after spraying or electroplating one by one. The manual filming is not only inefficient, but also the film is prone to bubbles and wrinkles, which seriously affects the filming quality of the metal sheet.

For example, the Chinese utility model patent with the announcement number of CN205588741U provides a semi-automatic steel plate laminating machine, which includes a conveying roller and two sets of upper and lower pressing rollers arranged in parallel and spaced apart. The plate is directly placed on the conveying roller, and the plate is manually pushed by , so that the sheet passes between the upper and lower pressing rollers.

However, the above-mentioned prior art solutions have the following defects: when the sheet material passes between the upper pressing roller and the lower pressing roller, the sheet needs to be able to pass between the upper pressing roller and the lower pressing roller along a certain conveying track. However, in the prior art solution, the board is placed only by manually observing the passing position of the board, which is difficult to ensure the accurate placement position of the board. The coating on the surface of the board is scratched or missing due to the film paper, so that the board cannot be maintained and the quality of the board is affected.

Utility model content
