Description
Technical field
The present invention relates to a kind of emebosser and its production technology, specifically a kind of surface forming emebosser of PVB films
And its production technology, belong to embossing device technical field.
Background technology
Polyvinyl butyral resin (PVB) film is the sandwich material for making safety glass.Because its transparency is good, impact is strong
Degree is big, is widely used in aviation and automotive field.Specifically, safety glass is that one layer is added between two layers of simple glass
With weather-proof, sound insulation, every the special glass of the performances such as ultraviolet good polyvinyl butyral film piece.Safety glass can be
By apparatus with shock absorbing during foreign impacts so that this glass is not crushed, safeguard protection is formed.
Prior art, Patent No. 2011203905638 discloses a kind of production for pvb film double-sided embossing and set
Standby, its technical scheme is the cooperation by pre- hot-rolling and chill roll, realizes two-sided cooling and the stamp of pvb film, and the production is set
The problem of standby mainly solution is that speed of production is slow, less efficient, and domestic output is difficult to meet existing market needs.But, should
Technical scheme has two defects：One is, the production equipment is to first pass through pre- hot-rolling preheating, then passes through the first reticulate pattern steel rider and second
The embossing of reticulate pattern steel rider, forms various patterns, and pvb film, can be by a segment distance to reticulate pattern steel rider after preheating, this
In segment distance, can cause the temperature of pvb film reduces, and is not enough to be formed the embossed pattern of high-quality, then through supercooling, can be further
So that flow is complicated, and cooling step seems unnecessary in this equipment；Two are, from pre- hot-rolling to reticulate pattern steel rider during,
Because transmitting range is long, PVB films can be caused to be constantly in tensioned state, and then the meeting in embossing process of PVB films can be made
The state for having fold or laminating, causes the success or failure of embossing.
Patent No. 2011201889700, discloses a kind of composite knurling device, the device be by upper knurling rolls and under
The cooperation of knurling rolls, forms embossed pattern.The problem of embossing device, is the synchronism and one of knurling rolls and lower knurling rolls
Cause property, if the rotation of upper knurling rolls and lower knurling rolls inconsistent (including rotating speed, flower roller angle, and between flower roller and tabletting
Frictional force etc.), it can all cause embossing quality reduction.
The content of the invention
The technical problem existed for above-mentioned prior art, the present invention provides a kind of surface forming emebosser of PVB films
And its production technology, the emebosser enables to PVB films to be embossed in heating, and causes PVB films are constantly in tighten shape
State, forms high-quality embossed pattern.
The present invention is achieved through the following technical solutions above-mentioned purpose：A kind of surface forming emebosser of PVB films, including
Pre-shaping device, embossing device and heater；
