The film material is transmitted between the conveying roller and the tension regulating mechanism. The tensioning force of the film material acts on the tensioning roller.

The plate drives the tensioning roller to move upward, thereby reducing the tensioning pressure of the tensioning roller on the film material, avoiding the problem of the film material being easily broken due to excessive tension, and when the film material tension is too loose, the tensioning roller is subjected to small reaction force from the film material, and the tensioning roller moves downward under the pulling action of the compensation spring, thereby making the conductive block contact with the reverse electrical contact block, connecting the reverse power supply circuit of the dual-axis motor, and then the lifting plate drives the trigger shell and the tensioning roller to move downward, thereby tightening the tension of the film material, avoiding the problem of the film material tension being too loose affecting the subsequent printing operation, and enabling the film blowing machine to have stable tensioning force adjustment, thereby ensuring the actual processing quality.
