Problems solved by technology

However, when a rotating die head is used, the rotating connection of the die head is prone to leakage; when a rotating winding frame is used, the rotating device is too bulky and heavy, and no matter whether a rotating head or a rotating winding frame is used, the structure is complicated. , the disadvantage of too high price
For example, the Chinese patent document CN2354735 discloses a "rotary film blowing machine with winding part", which uses a turntable rotating mechanism to drive the auxiliary machine (winding part) of the film blowing unit to rotate to achieve the purpose of eliminating the accumulated streaks in the curling process. , its structure is complex, bulky, not easy to manufacture

Abstract

A film bubble rotating apparatus of blow moulding machine is composed of a power unit, a fixing unit consisting of virtical drawing frame, position regulator and bottom plate, a rotating unit consisting of a rotating toothed ring and a supporting ring track, and a film bubble position limiter having two parallel guide rollers.

Description

technical field [0001] The invention relates to a blow molding machine, more particularly to a film bubble rotating device of the blow molding machine. Background technique [0002] In the traditional blown film production process, the die head, traction mechanism and winding mechanism are all in a relatively fixed position. Therefore, during the film forming process, the thick and thin points on the film bubble are continuously accumulated on the fixed point at the film roll. , so that the surface of the produced film is uneven, so that the flatness of the film development surface is deteriorated, and the strength of the film is reduced, thereby affecting the quality of the film and its application. [0003] At present, in order to improve the quality of plastic films, rotating die heads or rotating winding frames are generally used. However, when a rotating die head is used, the rotating connection of the die head is prone to leakage; when a rotating winding frame is used...
