Machine head flow channel corner non-dead-angle structure

Abstract

The invention relates to a machine head flow channel corner non-dead-angle structure, a machine head shunt is arranged on a main flow channel, a flow channel on the machine head shunt is correspondingly communicated with a sub flow channel on a flow channel spiral body installed on the outer side of the machine head shunt, a machine head coat is installed on the outer side of the flow channel spiral body, one opening of the sub flow channel is provided with a spiral flow channel, wherein the opening of the sub flow channel is located on one end of the machine head coat, and a plugged impression is installed in a corner connecting the sub flow channel and the spiral flow channel. The machine head flow channel corner non-dead-angle structure is characterized in that: the arc streamlined plugged impression is installed in the corner of a machine head branch flow channel, so that the dead angle at the corner is disappeared, a material can more smoothly flow in the corner of the branch flow channel, equipment process requirements of products can be met, and the appearance quality of film products can be improved.

Description

technical field [0001] The invention relates to the plastic film blowing industry, in particular to a structure with no dead angle at the corner of the flow channel of the plastic film blowing machine. Background technique [0002] The rationality of the design of the head of the core component of the plastic blown film production line directly affects the quality of the film product. With the development of the plastics industry, new materials and new varieties emerge in an endless stream. The structure design and parameter optimization of the head must keep up with the development of the plastics industry. , to meet the requirements of high-quality membrane products on the head, such as Figure 1-2 As shown, the corner of the branch channel of the existing plastic film blowing machine is a flow dead zone, and the resin flowing here becomes immobile. Under the high temperature heating of the machine head, it gradually becomes a paste, which seriously affects to product qual...
