Description
Technical field
The present invention relates to a kind of continuous producing method and production system of flat-shaped heat-shrink tube.
Background technology
Heat-shrink tube is general, and by extrusion, irradiation and expansion completion, it is produced.At present, heat-shrink tube has circular tube shaped heat-shrink tube（Circle
Pipe）With flat-shaped heat-shrink tube（Flat tube）Two kinds of forms.Unexpanded heat-shrink tube is expanded by dilatation mold forms circular tube shaped
Heat-shrink tube, by the pyrocondensation after expansion while flat-shaped heat-shrink tube then needs to be expanded unexpanded heat-shrink tube by dilatation mold
Pipe carries out extruding formation by extrusion die.
Flat tube is compared with pipe, not only because it takes less volumetric spaces and conveniently transported in flattening shape in packaging
Defeated, reduction cost of transportation, and be also easy to cut, improve Pipe Cutting quality in flattening shape in Pipe Cutting.
However, above-mentioned heat-shrink tube is squeezed by during circular tube shaped heat-shrink tube is changed into flat-shaped heat-shrink tube, volume is significantly
Reduce, and the air in original pipe flows along pipe to dilatation mold direction, and in the production in enormous quantities of flat-shaped heat-shrink tube,
The longer several kms of flat-shaped pyrocondensation length of tube that once produce, a few myriametres have, with expansion and the accumulation of extrusion time, due to squeezing
The air pressed and flowed to dilatation mold direction is more and more and can not discharge, and not only leads to not be expanded, and produce
Substandard products.
The content of the invention
It is an object of the invention to provide a kind of technique is simple and be easy to the continuous producing method of the flat-shaped heat-shrink tube of expansion.
To achieve the above object, the present invention provides a kind of continuous producing method of flat-shaped heat-shrink tube, will continuously expand
Heat-shrink tube afterwards carries out extruding and forms flat-shaped heat-shrink tube, is used during heat-shrink tube constantly advance after expansion two positions
Put a little（P, P '）Extrude simultaneously, in two location points（P, P '）Extrude simultaneously during, squeezed first in the pause of first position P points
The gas that pressing makes to suppress in the heat-shrink tube after first position P points flows forward from first position P points；Then opened in first position P points
Extruding is opened, putting pause extruding in second place P ' makes to suppress the gas flow forward in the heat-shrink tube after second place P ' points, so
After be then turned on second place P ' put extrude, circulated with this, so as to release gas in pipe during heat-shrink tube constantly advances
Run out.
The present invention also provides a kind of production system of the continuous producing method using above-mentioned flat-shaped heat-shrink tube, including driving wheel
Group, heater, dilatation mold and two groups of squeezing rollers, wherein drive wheel group, which drive heat-shrink tube to be expanded, to advance, to be expanded
The heated device heating of heat-shrink tube, is expanded subsequently into dilatation mold, most is extruded into form flat-shaped through two groups of squeezing rollers afterwards,
One of which squeezing roller is located at first position P points, and another group of squeezing roller is located at second place P ' points, and squeezing roller is in extruding
Squeezed state is in during heat-shrink tube, squeezing roller is in pause extruding heat-shrink tube in release release conditions.
Preferably, two groups of squeezing rollers use same drive motor.
As described above, the continuous producing method and its production system of flat-shaped heat-shrink tube of the invention pass through in two location points
（P, P '）Extrude simultaneously, and in two extrusion position points（P, P '）Gas is released to suspend fashion of extrusion, can be realized
Gas in pipe is discharged during heat-shrink tube constantly advances, method is simple, it is easy to expand, it is possible to increase product matter
Amount.
Brief description of the drawings
Fig. 1 is the continuous producing method of flat-shaped heat-shrink tube of the invention and the schematic diagram of production system.
Embodiment
To describe technology contents of the invention, process, the objects and the effects in detail, below in conjunction with embodiment
It is explained in detail.
The continuous producing method of the flat-shaped heat-shrink tube of the present invention forms flat the heat-shrink tube after continuous expansion is carried out into extruding
Shape heat-shrink tube.
Explanation is needed exist for, the heat-shrink tube extrusion, irradiation steps before expansion are this hairs due to being prior art, not
Bright emphasis, therefore repeat no more.
During the continuous producing method of the flat-shaped heat-shrink tube of the present invention is heat-shrink tube constantly advance after expansion, use
In two location points（P, P '）Extrude simultaneously, in two location points（P, P '）Extrude simultaneously during, first in first position P
The gas that point pause extruding makes to suppress in the heat-shrink tube after first position P points flows forward from first position P points；Then at first
Put P points and open extruding, putting pause extruding in second place P ' makes to suppress gas in the heat-shrink tube after second place P ' points forward
Flowing, is then then turned on putting extruding in second place P ', is circulated with this, so that in being managed during heat-shrink tube constantly advances
Gas is discharged.
Referring to Fig. 1, flat-shaped heat-shrink tube production system of the invention includes drive wheel group 1, heater 2, the and of dilatation mold 3
Two groups of squeezing rollers 4, one of which squeezing roller 4 is arranged on first position P points, and another group of squeezing roller 4 is arranged on second
Put P ' points.
Heat-shrink tube 5 to be expanded is driven advance by drive wheel group 1, and the heated device 2 of heat-shrink tube 5 to be expanded is heated, Ran Houjin
Enter dilatation mold 3 to be expanded, during the constantly advance of heat-shrink tube 5 after expansion, in first position, P points are squeezed using one group
Heat-shrink tube 5 after 4 pairs of expansions of pressing roller carries out continuously extruded, another group of use of P ' points 4 pairs of the squeezing roller expansion in the second place
Heat-shrink tube 5 afterwards carries out continuously extruded, and initial state is that two groups of squeezing rollers 4 are extruded simultaneously.
The extruding for suspending squeezing roller 4 in first position P points first makes to suppress in the heat-shrink tube after first position P points
Gas flows forward from first position P points；Then the extruding of squeezing roller 4 is opened in first position P points, P ' points are temporary in the second place
Stopping the extruding of squeezing roller 4 makes to suppress the gas flow forward in the heat-shrink tube after second place P ' points, is then then turned on the
Two position P ' point extruding, is circulated with this, so as to discharge gas in pipe during heat-shrink tube constantly advances.
Squeezing roller 4 is in squeezed state when extruding heat-shrink tube 5, and squeezing roller 4 is in pause extruding heat-shrink tube
Unclamp release conditions.
As further improvement of this embodiment, two groups of squeezing rollers 4 use same drive motor.
In summary, the continuous producing method and its production system of flat-shaped heat-shrink tube of the invention pass through in two location points
（P, P '）Extrude simultaneously, and in two extrusion position points（P, P '）Gas is released to suspend fashion of extrusion, Neng Goushi
Present heat-shrink tube discharges gas in pipe during constantly advancing, and method is simple, it is easy to expand, it is possible to increase product matter
Amount.
The invention is not limited in above-mentioned embodiment, those skilled in the art can also make a variety of accordingly
Change, but any be equal or similar change should all be covered within the scope of the claims with of the invention.
