Abstract

The utility model relates to a film blowing machine of a rolling and rotating type, which adopts a rotary disk type rotary mechanism to drive the auxiliary machine (a rolling part) of the film blowing machine set to rotate. Thus the film of uneven thickness caused by the reasons of the die head precision, etc. in the blow molding process can be distributed evenly. Thereby, the accumulated streaks in the rolling process can be eliminated, and the problem of smoothly rolling the film can be solves. The utility model comprises a top blowing type and a bottom blowing type, and is suitable for producing single-layered films and composite films, which is suitable for various die heads.

Description

The rotary inflation film manufacturing machine of rolling portion

The rotary inflation film manufacturing machine of rolling portion belongs to field of plastics processing.

At present, the single thin film inflation film manufacturing machine of employing is produced the outlet film and is not reached the needs in film printing field, in order to make the film of producing smooth, takes the main frame rotation, makes equipment huge, complexity, and cost height.

Satisfy the needs of film printing in order to reach on the single thin film performance.The utility model purpose is that to adopt the random rotating mechanism to reach cost low, and film batches smooth problem.

The utility model is achieved in that the rolling portion at the subsidiary engine of film inflation film manufacturing machine is coaxially installed with the rotation roulette machine.

Fig. 1, upward type processing film machine structure diagram;

Fig. 2, bottom blowing type processing film machine structure diagram.

With reference to the accompanying drawings the utility model is described further:

Among Fig. 1, the extruder 1 of upward type film inflation film manufacturing machine below, die head 2 vertically upward, there are airduct 3 coolings die head top, the rolling portion 7 coaxial belows on the subsidiary engine are rotation roulettes 6, traction pair roller 5 is above random.

Among Fig. 2, the extruder 1 of bottom blowing type film inflation film manufacturing machine up, die head 2 vertically downward, it is that water pipe 4 cools off that die head below has under airduct 3 airducts 3, the rolling portion 7 coaxial belows on the subsidiary engine are swiveling wheels 6, traction pair roller 5 is below random.

Adopt swiveling wheel to drive the rotation of rolling portion, make the film thickness that blows out even, rolling is smooth, has increased intensity, to be fit to the needs of film printing.

Claims

1, the rotary inflation film manufacturing machine of rolling portion, by extruder, die head, cooling device, random is formed, and it is characterized in that: on subsidiary engine rolling portion is coaxial rotation roulette is installed.

2, inflation film manufacturing machine according to claim 1 is characterized in that: extruder below, die head has airduct vertically upward on the die head, the traction pair roller above random.
