Compression roller mechanism for blown films

Abstract

The invention relates to the field of film production, in particular to a compression roller mechanism for blown films. The compression roller mechanism for the blown films comprises a bearing frame, a supporting mechanism, extrusion rollers and a moving and pushing mechanism. The supporting mechanism comprises two supporting units, each supporting unit comprises two supporting strips and multiple film guiding pipes, and each film guiding pipe comprises a first pipe body, a second pipe body and a connecting rod. The moving and pushing mechanism comprises a moving and pushing frame, a moving and pushing rod, a barrel, connecting pipes and lantern rings, the lantern rings are fixedly arranged on the supporting strips, and the moving and pushing frame can push the extrusion rollers to move. One ends of the first pipe bodies are connected with one ends of the second pipe bodies through the connecting rods, one ends of the second pipe bodies are rotationally connected with the lantern rings,the connecting rods are located at flow dividing holes, annular grooves are formed in the inner side walls of the other ends of the second pipe bodies, springs are connected in the annular grooves, and the free ends of the springs are connected with blocking plates arranged in the annular grooves in a sliding manner. When the technical scheme is adopted, the film production quality can be better improved.

Description

technical field [0001] The invention relates to the field of film production, in particular to a pressing roller mechanism for blown film. Background technique [0002] After the blown film machine blows out the tubular film, the film passes through two rows of inclined guide rollers under the traction of the traction roller, and the tubular film gradually becomes flat, and the two extrusion rollers finally extrude the film into a sheet containing two film of film. [0003] On the one hand, the function of the two squeeze rollers is to squeeze the two layers of film into one layer of film; final film quality. [0004] When the extrusion mechanism of the blown film machine is uneven or the raw material is not sufficient during a certain period of time during the film blowing process, the thickness of the film will become thinner. In this case, the film is flat and then passes two extrusions When rolling, the air blown out by the film blowing machine will enter between the ...

[0004] When the extrusion mechanism of the blown film machine is uneven or the raw material is not sufficient during a certain period of time during the film blowing process, the thickness of the film will become thinner. In this case, the film is flat and then passes two extrusions When rolling, the air blown out by the film blowing machine will enter between the two layers of film, resulting in bubbles inside the film, which will directly affect the quality of the film
