Technical field
The utility model is related to bubble chamber film technical field of processing equipment, more specifically, it relates to which a kind of bubble chamber film is molded
Roller and bubble chamber film machine.
Background technology
Bubble chamber film is also bubble cushion, is the New Plastic Packing Materials that a kind of quality is light, the transparency is good, non-toxic and tasteless, can
The effects that damp proof, buffering, heat preservation are played to product, is widely used in the packaging of commodity.
The equipment for producing bubble chamber film is bubble chamber film machine, as the Chinese patent that patent announcement number is CN206217315U proposes
A kind of temperature control bubble chamber film machine, primary structure include pedestal, column, wind turbine, die head, bottom film, bubble layer film, shaping mould
Tool, roller, heating tube, sink and control panel.Wherein molding die in actual production mainly include bubble chamber film forming roller with
And vacuum pump, on bubble chamber film forming roller, the number of plies of plastic film is generally two layers the plastic film squeezed out by die head（
There is also the situations of three-layer thin-film in practice）, the shaping groove to gather on bubble chamber film forming roller is connected with vacuum pump, by into
The absorption of type groove so that the thin film for being close to bubble chamber film forming roller generates recess, then covers upper second layer film, so as to
Bubble is generated in the film of final molding.
Since the high-temperature fusion shape plastic film temperature squeezed out from die head is very high, it usually needs add on bubble chamber film forming roller
To be molded cooling.The mode cooled down at present mainly has air-cooled and water cooling, and air-cooled cooling efficiency is not as good as water cooling, the mode of water cooling
Predominantly：Water-cooling channel is set by the position of near surface in bubble chamber film forming roller, cold water is led in water-cooling channel so that entire
