The processing of existing hot-pressing light guide plate is mostly to carry out hot pressing site operation, such as Fig. 1 to light guide plate plank using hot press
It is shown, it is specific as follows in specific production process, it first passes through charging conveying roller band 5 and light guide plate plank 3 is delivered to 1 He of pressure roller
Between hot-pressing roller 2, site is then processed by pressure roller 1 and hot-pressing roller 2 and generates product 4, wherein in order to ensure light guide plate
The surface of quality, the common hot-pressing roller 2 used is shiny surface.
When the thinner thickness of pressed light guide plate plank 3 or higher pressed temperature, since pressure acts on so that light guide plate plate
It will produce bonding absorption between material 3 and hot-pressing roller (i.e. lower roll), causing such reason, there are two types of situations：One is work as light guide plate
When the thinner thickness of plank 3, and the surface of hot-pressing roller 2 is shiny surface, between light guide plate plank 3 and the surface of hot-pressing roller 2
After air is emptied completely, atmospheric pressure that light guide plate plank 3 can be subject to and make light guide plate plank 3 that can be pasted onto hot-pressing roller 2
On surface, another kind be when the temperature of light guide plate plank 3 is higher, and the surface of hot-pressing roller 2 be shiny surface, light guide plate plank 3
It can be become strong by stickiness after hot pressing, the viscous viscous force for the atmospheric pressure and light guide plate plank 3 itself for causing light guide plate plank 3 that can be subject to
Influence and make light guide plate plank 3 can be pasted onto on the surface of hot-pressing roller 2, as shown in Figure 2.
Utility model content
In order to solve the above technical problems, we have proposed a kind of hot press anti-sticking roller, purpose：Prevent light guide plate plank meeting
It is pasted onto the surface of hot-pressing roller.
In order to achieve the above objectives, the technical solution of the utility model is as follows：
A kind of hot press anti-sticking roller, including hot pressing roller main body are coated with steel plate in the middle part of hot pressing roller main body, and steel plate is equipped with
At least ten bulge-structures；
The top of bulge-structure is higher than surface of steel plate, and the minimum range between the top and surface of steel plate of bulge-structure is 0
To 0.3 μm.
Preferably, the steel plate of bulge-structure surrounding is equipped with the slot that loses heart, and the center of bulge-structure is equipped with groove.
Preferably, the minimum range between the top and surface of steel plate of bulge-structure is 0.2 μm.
Preferably, the quantity of bulge-structure is 120.
Another embodiment according to the present utility model, bulge-structure are circular protrusions structure.
Another embodiment according to the present utility model, bulge-structure are hexagon bulge-structure.
Another embodiment according to the present utility model, bulge-structure or is polygon bulge-structure or be top surface is hemispherical
Bulge-structure.
Through the above technical solutions, being coated with steel plate in the middle part of hot pressing roller main body, steel plate is equipped at least ten protrusions and ties
Structure can ensure that between light guide plate plank and hot-pressing roller without adsorption capacity, not will produce adsorption effect, solve guide-lighting in process
The problem of plate absorption adhesion hot-pressing roller.
