Description
Technical Field
[0001] The utility model relates to the technical field of film blowing machines, in particular to a film width regulating device for film blowing machines. Background Art
[0002] The film blowing machine is a special equipment used to heat and melt plastic particles and pass them through an extruder and a die to produce film. During the film blowing process, the molten plastic is filtered through the die and extruded by the heated die. It is cooled by the cold air inside and outside the environment and blown into a film bubble. Finally, the formed plastic film is rolled up by the winding device.
[0003] However, the winding device will over-stretch the film when winding it. Over-stretching means that the tension applied by the winding device when winding the film is too large, which exceeds the bearing capacity of the film, causing the film to deform, thereby reducing the production and winding quality of the film. In view of this, we propose a film width adjustment device for a film blowing machine. Utility Model Content

[0009] A guide roller is rotatably connected to the inner wall of the mounting frame.
[0010] Preferably, a groove is formed on the side wall of the guide roller, and the groove is arranged in a V-shape.
[0011] Preferably, the top end surface of the base is fixedly connected to a motor 1, the output end of the motor 1 is fixedly connected to a rotating shaft, the rotating shaft is transmission-connected to a rotating rod via a sleeved belt, the motor 1 drives the rotating shaft to rotate, and then drives the rotating rod to rotate via the transmission of the belt.
[0012] Preferably, a sliding rod is fixedly connected to the top inner wall of the second mounting frame, and the sliding rod is slidably connected to the cross bar. The sliding rod limits the cross bar so that the cross bar can only move vertically.
[0013] Preferably, there are two groups of tightening rollers, which are symmetrically arranged on both sides of the guide arc plate.

The cross bar 16 is threadedly connected with a tightening roller 17. There are two groups of tightening rollers 17. The two groups of tightening rollers 17 are symmetrically arranged on both sides of the guide arc plate 13. The pressure on the film is adjusted according to the thickness of the film through the two groups of tightening rollers 17 to prevent the film from being deformed due to excessive pulling. The top inner wall of the mounting frame two 11 is fixedly connected with a slide bar 18, and the slide bar 18 is slidably connected with the cross bar 16.
