Description
Technical field
This utility model is related to a kind of microprism formable layer device.
Background technology
Known, reflective membrane is that, using optical reflex reflection principle, its reflector element can be divided into glass microballoon and microprism
Two types, the reflective membrane with microprismatic retroreflective unit are more and more widely employed due to its remarkable retroreflective energy
In fields such as different kinds of roads traffic safety facilities, sign board and vehicle passive security preventers.Its principle is in plastic-based film
Surface forms equally distributed microprism array structure, and so-called microprism array structure refers to perpendicular to each other each other by three
The structure constituted by plane, can carry out total internal reflection to the incident illumination from front surface, so as to greatly improve to incident illumination
Reflection efficiency.In prior art, generally using film hot-pressing method come molding microprism layer, this method needs to make plastic sheeting
Moment reaches melt temperature and the plastic sheeting after melting is got into mould, cause to produce after microprism formable layer numerous air-bubble,
Shaping structures are not full enough, brightness is low and uneven.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, to propose a kind of microprism formable layer device, molding
Microprism layer is full, no bubble, reflective function are good.
This utility model is achieved through the following technical solutions：
A kind of microprism formable layer device, for forming the microprism layer of Microprism reflective membrane, including being oppositely arranged in parallel
Hot-rolling and chilling roller, around being stretched between hot-rolling and chilling roller and outer surface has the ring mould band of microprism shaping mould, drive
Dynamic chilling roller and hot-rolling are rotated makes drive mechanism of the ring mould with cycle operation, with the running speed of ring mould band by continuous defeated
The conduction band that send, for being cast the casting device to form cast layer in conduction band top surface, one section of conduction band be stretched in hot-rolling and chilling roller it
Between and be stacked in the outer surface of ring mould band, from hot-rolling input chilling roller output, cast layer is cast to defeated conduction band by casting device
Enter the conduction band top surface before hot-rolling, make the cast layer that flow casting molding not yet solidifies be formed micro- by the microprism shaping mould hot pressing at hot-rolling
Prism structure Jing chilling roller cooling and shapings.
Further, the conveyer device also including continuous conveying conduction band, the conveyer device includes parallel with the hot-rolling
The first tangent pressure roller the second tangent pressure roller parallel with the chilling roller, conduction band are folded through rear between hot-rolling and the first pressure roller
Put the outer surface in the ring mould band, after the hot-forming microprism layer chilling roller cooling and shaping described in of the hot-rolling described in from
Rear entrance subsequent operation is passed through between chilling roller and the second pressure roller.
Further, the conduction band is PET film.
Further, the casting device is casting machine.
Further, the microprism shaping mould is distributed with the groove to form micro-prism structure.
This utility model has the advantages that：
Cast layer is cast to the conduction band top surface before input hot-rolling by casting device of the present utility model, makes flow casting molding not yet
The cast layer of solidification is formed micro-prism structure Jing chilling roller cooling and shapings by the microprism shaping mould hot pressing at hot-rolling, makes full use of
Mobility and plasticity after plastic material melting, the microprism layer of molding is full, no bubble, brightness uniformity, reflective function
More preferably, and conduction band is heat-resisting smooth PET film, can keep smooth at high temperature, make Microprism reflective membrane more smooth.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is described in further details.
Fig. 1 is structural representation of the present utility model.
Specific embodiment
As shown in figure 1, this utility model is used for forming the microprism layer of Microprism reflective membrane, including what is be oppositely arranged in parallel
Hot-rolling 1 and chilling roller 2, around being stretched between hot-rolling 1 and chilling roller 2 and outer surface has the ring mould band of microprism shaping mould
3rd, drive chilling roller 2 and hot-rolling 1 rotate make ring mould operate with 3 left-hand circulars drive mechanism, with ring mould with 3 fortune
Conduction band 4 that rotary speed is fed continuously, for being cast the casting device 5 to form cast layer in 4 top surface of conduction band and continuous conveying is led
The conveyer device of band, a section of conduction band 4 are stretched between hot-rolling 1 and chilling roller 2 and are stacked in ring mould with 3 outer lower face surface,
Conduction band 4 is exported from the input of hot-rolling 1 chilling roller 2, and in the present embodiment, conduction band 4 is PET film, and conveyer device includes parallel with hot-rolling 1
Tangent the first pressure roller 6, the second tangent pressure roller 7 parallel with chilling roller 2, after conduction band 4 is passed through between hot-rolling 1 and the first pressure roller 6
Ring mould is stacked in 3 outer surface, Jing the hot-forming microprism layer 9 of hot-rolling 1 Jing after 2 cooling and shaping of chilling roller from chilling roller 2
And second enter winding, and the subsequent operation such as other layers of Microprism reflective membrane are compound through rear between pressure roller 7, casting device 6 is
Casting machine, microprism shaping mould of the ring mould with 3 outer surfaces are distributed with the groove to form micro-prism structure.
Utility model works principle is as follows：
Conduction band 4 top surface of the PC plastic materials Jing after casting machine high-temperature fusion before input hot-rolling is cast to form certain thickness
Cast layer 8, makes the cast layer that flow casting molding not yet solidifies be formed micro-prism structure simultaneously by the microprism shaping mould hot pressing at hot-rolling 1
2 cooling and shaping of Jing chilling rollers can form microprism layer 9, and by adjusting the thickness of the whole cast layer of casting machine Parameter adjustable 8, cooling is fixed
Microprism layer 9 after type also includes strippable conduction band layer.
The above, preferred embodiment only of the present utility model, therefore this utility model enforcement can not be limited with this
