Technical field
The utility model relates to a kind of heat shrinking sleeve process equipment, is specifically related to a kind of twin shaft rotation type heat shrinking sleeve extension fixture.
Background technology
Heat shrinking sleeve is to need not any external force after a kind of heating can shrink automatically, tightly wraps up by the suit object, realizes the good parcel and the product of sealing function, and be used widely in the field in that packaging for foodstuff, electric sealing and petroleum pipeline be anticorrosion etc.
In the production process of thermal shrinkable sleeve, an important step is that heat shrinking sleeve is expanded typing.At present, the expansion method of heat shrinking sleeve mainly contains two kinds: negative pressure/inflatable dilatation method and core expansion method.United States Patent (USP) (US3427638) and Chinese patent (200820056772.7) are negative pressure/inflatable dilatation method; Japan Patent (S-47-37506) and Chinese patent (86105828A) are core expansion method.The expansionary force that negative pressure/inflatable dilatation method mainly utilizes the pressure differential of thermal contraction jacket wall both sides to produce is realized expansion, but because negative pressure/inflation use is draught head, the pressure that acts on tube wall is less, usually be applicable to the expansion of the thermal contraction casing tube of the little caliber of thin-walled, for example wire insulation sealing expansion of heat-shrinkable tube etc.Core expansion method is to use a fixedly expansion core of caliber, enters and keeps the expansion of whole heat shrinking sleeve is realized from heat shrinking sleeve one end.In order to make heat shrinking sleeve increase radial dilatation as far as possible, reduce elongation vertically, generally between expansion core and heat shrinking sleeve, add steel wire or adopt film to isolate.When adopting the expansion core that heat shrinking sleeve is expanded, in case core determines that the expansion caliber of heat shrinking sleeve also determines thereupon, so equipment usually needs to be equipped with the expansion core of a plurality of different tube diameters.Because the expansion core is when one enters heat shrinking sleeve, the upstream end heat shrinking sleeve is expanded, and upstream end does not still maintain the original state, so usually make heat shrinking sleeve in the process of expansion produce radially elongation, radial contraction amount considerable influence product quality during use.Use this method expansion heat shrinking sleeve, the expansion multiplying power can not be excessive, otherwise occur the heat shrinking sleeve fracture phenomena easily.
In engineerings such as pipeline corrosion protection, the pipeline model is more, and caliber is also bigger, usually needs to use the big caliber thermal contraction casing tube of different model to carry out anticorrosion to buried steel pipeline.At present, the expansion of big caliber heat shrinking sleeve has following problem:
(1) heat shrinking sleeve expansion multiplying power is bigger, and process of expansion needs slowly to stretch.If rate of extension is too fast, easily cause the heat shrinking sleeve cracking;
(2) control of process of expansion temperature is difficult, and heat shrinking sleeve at first needs to be heated to the expansion temperature, remains on simultaneously under this temperature and expands;
(3) equipment is had relatively high expectations, the expansion of big caliber heat shrinking sleeve needs bigger expansionary force, uses negative pressure or aeration to be difficult to reach elevated pressures;
(4) the expansion uniformity requirement is higher, heat shrinking sleeve in whole process of expansion, be difficult to accomplish stressed evenly, expansion fully, it is even and form substandard products or waste product to occur wall unevenness easily.
In a word, present employed heat shrinking sleeve expansion method, expansionary force and expansion multiplying power are less, only are applicable to the heat-shrinkable tube that caliber is little, wall is thin, and be comparatively difficult for the heat shrinking sleeve processing of big caliber, heavy wall.
