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
The present invention relates to plastic membrane blowing industry is and in particular to a kind of flow channel turning no dead angle of plastic film blowing machine is tied
Structure.
Background technology
The reasonability of plastic membrane blowing production line core component Die Design directly influences the quality of membrane product quality, with
Plastics industry, new material, new varieties emerge in an endless stream, and handpiece structure design, the optimization of parameter must keep up with plastics industry
Development, meets the requirement to head for the high-quality film product, as shown in Figure 1-2, the head branch flow passage turning of existing plastic film blowing machine
Locate as flow dead, the resin flowing to herein is changed into motionless state, under the high-temperature heating of head, slowly becomes thickener, seriously
Have influence on quality of item.
Content of the invention
It is an object of the invention to overcoming above-mentioned deficiency problem, provide a kind of flow channel turning no dead angle structure.
The present invention be employed technical scheme comprise that for achieving the above object：Flow channel turning no dead angle structure, sprue
On flow divider for nose is installed, the runner on flow divider for nose is corresponding with the sub-runner being arranged on the runner spirillum outside it
Connection, installs head overcoat outside described runner spirillum, described sub-runner is located at and offers at the opening of head overcoat one end
Helical flow path, the corner that described sub-runner is connected with helical flow path is provided with abaculus.
The pipes' analysis of described abaculus are circular arc streamline.
Described abaculus is installed between runner spirillum and head overcoat.
It is characteristic of the invention that：In the fusiform abaculus of head branch flow passage corner insert circular arc, corner dead angle is made to disappear
Lose, material is more smooth in the flowing of branch flow passage corner, meets the technological requirement to equipment for the product, improves the outward appearance matter of membrane product
Amount.
Brief description
Fig. 1 is traditional flow channel structure chart；
Fig. 2 is traditional flow channel corner structure figure；
Fig. 3 is present configuration figure.
Wherein：1st, head overcoat 2, runner spirillum 3, flow divider for nose 4, sprue 5, sub-runner 6, spiral flow
Road 7, abaculus.
Specific embodiment
As shown in figure 3, the present invention is flow channel turning no dead angle structure, sprue 4 is provided with flow divider for nose 3,
The connection corresponding with the sub-runner 5 being arranged on the runner spirillum 2 outside it of runner on flow divider for nose 3, described runner spiral shell
Head overcoat 1 is installed in rotation body 2 outside, and described sub-runner 5 is located at and offers helical flow path 6, institute at the opening of head overcoat 1 one end
State the corner that sub-runner 5 is connected with helical flow path 6 and abaculus 7 is installed, described abaculus 7 is installed in runner spirillum 2 and head
Between overcoat 1, the pipes' analysis of described abaculus 7 are circular arc streamline, so that dead angle is disappeared by adding circular arc streamline abaculus 7, point
Runner 5 turning Flow of Goods and Materials is more smooth, meets the technological requirement to equipment for the product, improves membrane product presentation quality.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
