If the two press rolls 21 are connected in the connecting groove 112 only through the corresponding first adjusting screw 23, when the film is conveyed, the tension is affected, the two press rolls 21 driven to rotate are subjected to the action of traction force, and shift occurs along the connecting groove 112 in the horizontal direction, the phenomenon that the two press rolls 21 gradually get close to the middle occurs, the distance between the two press rolls 21 becomes smaller gradually, and therefore the film conveying is affected, and even the film is broken. The spring piece 22 can limit and buffer the compression rollers 21, and correct the positions of the two compression rollers 21, so that the interval between the two compression rollers 21 is always kept in a range suitable for material transmission and material pressing in the material transmission process.
