Description

Cutting device of film blow molding machine

Technical Field

The utility model belongs to film blowing field, specifically speaking relates to a film blowing machine cutting device.

Background

Film blowing is a process for continuously forming plastic film by using an extrusion method, in which resin is added into an extruder, the resin is melted under the action of conveying, shearing and heating by an internal screw, the melted material is conveyed into a blowing machine head, an annular film tube with uniform thickness is continuously extruded from an annular die head discharge port through a filter screen and a porous plate, and a proper amount of compressed air is blown into the film tube from the lower part of the blowing machine head to radially blow the film tube. The membrane tube is drawn in by the lambdoidal plate and is pressed the fold back and is pressed the tight vertical draft of clamp by traction roller on traction frame upper portion, need cut it into the slice before rolling it, but in current cutting process, can only cut into two with the membrane tube, can't satisfy the requirement of cutting into four, and the membrane tube is generally two films before cutting out and is pasted together, directly is torn easily by the traction roller in-process.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a film blowing machine cutting device for guide plastic film can be cut into four with the film simultaneously.

In order to achieve the above object, the utility model adopts the following technical scheme:

including fixed guide arm, slidable is fixed with cutting knife subassembly on the dead lever, fixed guide arm middle part is equipped with vertical ascending pole setting, the top of pole setting has set firmly circular cutting knife, be equipped with the telescopic horizontal pole on the stand circumference lateral wall, the horizontal pole with fixed guide arm is parallel and is located same vertical plane, the free end of horizontal pole is equipped with the edge horizontal pole pivoted swiveling wheel.

Preferably, a track notch and a fixed notch are formed in the fixed guide rod, the cutting knife assembly is embedded in the track notch and can slide in the track notch, the track notch is formed in the top end face of the fixed guide rod, the fixed notch is formed in the side wall of the fixed guide rod, the track notch and the fixed notch are communicated with each other, and the cutting knife assembly is fixed through a screw rod penetrating through the fixed notch.

Preferably, the cutting knife assembly comprises a base and a support, the base is vertically connected with the support, an inclined cutting knife is arranged between the base and the support, the base is embedded in the track groove, and a threaded hole matched with the screw rod is formed in the joint of the base and the support.

Preferably, the cutting knife is positioned right below the circular cutting knife.

Preferably, the outer wall of the fixed guide rod between the track notch and the fixed notch is provided with scale marks.

The utility model discloses owing to adopted foretell structure, it compares with prior art, and the technical progress who gains lies in: the utility model discloses but the top in the pole setting sets up circular cutting knife, and when plastic film passed through, circular cutting knife cut plastic film earlier, falls into two with the film. Be equipped with the swiveling wheel at the free end of horizontal pole for guide and separation to the film, the horizontal pole is the telescopic simultaneously, and cutting knife subassembly also can slide fixedly on fixed guide arm, therefore horizontal pole and cutting knife subassembly also can be adjusted according to the different length of membrane pipe diameter, fix the membrane pipe in order to correspond the different diameters in different positions.
