Description
Technical field
The utility model relates to field of plastics processing, is specifically related to a kind of EVA glued membrane high-speed production modular system.
Background technology
EVA is a kind of typical random macromolecular compound, in its molecular structure, the irregular arrangement of substituting group on strand, in strand, the configuration of asymmetric carbon atom is not identical yet simultaneously, arrange also irregular, therefore it be that a kind of crystallinity is less, polarity and the higher material of pliability, it has good wellability when heating and melting in addition, during cooling curing, there is good flexibility, anti-stress cracking and adhesive property, be a kind of comparatively desirable can be for the material of solar cell package.
While producing EVA glued membrane, plastic pellet, first through extruder melting, is then extruded formation film by the mould in certain gap, then through the rapid cooling curing of embossing, through drawing respectively by thickness measuring and cutting apparatus, finally by rolling-up mechanism, the glued membrane rolling of curing molding is packed again.In the process of extrusion molding fused film sector-meeting be subject to before tensile stress on line direction, once after the rapid cooling curing of glued membrane, this stress will be set in glued membrane, and in distraction procedure, glued membrane also will produce certain deformation under the pulling force effect of front line direction.When lamination heats again, glued membrane will cause contraction by this Stress Release, has a strong impact on component lamination quality, causes existing conventionally can only remain on≤2m/min of EVA glued membrane line speed, and production efficiency is low.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of EVA high-speed production modular system, the glued membrane that can reduce to greatest extent after solidifying is subject to the pulling force in direction of advance, can make the stress being set in glued membrane discharge in advance, the product size of producing is stable, shrinkage factor is little, produces linear speed high.
For achieving the above object, the utility model adopts following technical scheme:
An EVA glued membrane high-speed production modular system, is characterized in that: mainly comprise crawler-tread device, constant temperature heating device and air cooling equipment, described constant temperature heating device and air cooling equipment are arranged in order along the transmission direction of crawler-tread device.
Further, described constant temperature heating device mainly comprises heating tube, for controlling the first temperature controller of heating tube temperature, and temperature regulating range is between 35 ℃～55 ℃, and internal temperature field distribution is even.Constant temperature heating device can regulate front and back along the transmission direction of crawler-tread device, but before need being positioned at air cooling equipment.
Further, described air cooling equipment mainly comprises blowing device, for controlling the second temperature controller of blowing device temperature, and temperature regulating range is between 10 ℃～25 ℃, and wind-force size is adjustable, and air inlet and air outlet place are equipped with screen.Air cooling equipment can regulate front and back along the transmission direction of crawler-tread device, but after need being positioned at constant temperature heating device.
The beneficial effects of the utility model are:
A kind of EVA glued membrane high-speed production modular system of the present utility model, by adopting crawler belt transmitting device, constant temperature heating device and air cooling equipment, the glued membrane that can reduce to greatest extent after solidifying is subject to the pulling force in direction of advance, can make the stress being set in glued membrane discharge in advance, the product size of producing is stable, shrinkage factor is little, produces linear speed high.The utility model is simple in structure simultaneously, and low cost of manufacture, has good application value.
Accompanying drawing explanation

Wherein: 1, crawler-tread device; 2, constant temperature heating device; 3, air cooling equipment.
The specific embodiment
Below, by reference to the accompanying drawings and the specific embodiment, the utility model is described further:
As shown in Figure 1, for a kind of EVA glued membrane of the utility model high-speed production modular system, mainly comprise crawler-tread device 1, constant temperature heating device 2 and air cooling equipment 3, described constant temperature heating device 2 and air cooling equipment 3 are arranged in order along the transmission direction of crawler-tread device 1.Crawler-tread device 1 is equipment of the prior art, comprises crawler belt and speed changer, and the speed of crawler-tread device 1 can regulate by speed changer.
Further, described constant temperature heating device 2 mainly comprises heating tube, for controlling the first temperature controller of heating tube temperature, and temperature regulating range is between 35 ℃～55 ℃, and internal temperature field distribution is even.Constant temperature heating device 2 can regulate front and back along the transmission direction of crawler-tread device 1, but before need being positioned at air cooling equipment 3.
Further, described air cooling equipment 3 mainly comprises blowing device, for controlling the second temperature controller of blowing device temperature, and temperature regulating range is between 10 ℃～25 ℃, and wind-force size is adjustable, and air inlet and air outlet place are equipped with screen.Air cooling equipment 3 can regulate front and back along the transmission direction of crawler-tread device 1, but after need being positioned at constant temperature heating device 2.
The operation principle of a kind of EVA glued membrane high-speed production modular system of the utility model embodiment is as described below:
EVA glued membrane after cooling curing is transmitted and enters constant temperature heating device 2 without stretching by crawler-tread device 1, after the thermal finalization pretreatment of uniform temperature and time, the internal stress that makes to be set in glued membrane discharges in advance, continuation is transmitted and enters air cooling equipment 3 without stretching by crawler-tread device 1, make glued membrane after thermal finalization cooling and shaping again, prevent that glued membrane from stretch producing deformation through subsequent thermal, finally by cutting, rolling-up mechanism packs the glued membrane rolling of curing molding.By making glued membrane size in stable state after this equipment, when lamination heats again, product maximum contraction rate≤2%, and more than EVA glued membrane production line scooter 10m/min.
for a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion all should belong to the protection domain of the utility model claim within.
