Online hot pressed composite panel production equipment and production process thereof

Abstract

The invention discloses online hot pressed composite panel production equipment which comprises a drier, a dedustor, a distributor, a single screw extruder, a full-automatic multi-layer coextrusion clothes rack die head, a multi-roll calender, a slow cooling rack, a defect detector, a thickness detector, a temperature equalizer, a precise temperature hot press, a traction mulch applicator, an edge cutting traction machine, a transverse cutting machine and a manipulator. A production process of the online hot pressed composite panel comprises the specific steps: S1, material selection; S2, drying; S3, material supply; S4, hot melting; S4, extrusion calendaring forming; S6, cooling and detection; S7, temperature control and hot pressing; and S8, tailoring and stacking. According to the online hot pressed composite panel production equipment and the production process thereof, one material is used and is primarily calendered and formed, so that the manufacturing process is simple, the production efficiency is high, the overall cost is low, the environment is little in influence, and the product is good in transmittance.

Description

technical field [0001] The invention relates to a composite plate production equipment and process, in particular to an online hot-pressed composite plate production equipment and a production process thereof, and belongs to the technical field of optical diffusion plate and light guide plate production. Background technique [0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then the high-tech material with high reflectivity and non-absorbing light is used to print light-guiding points on the bottom surface of the optical-grade acrylic sheet with UV screen printing technology; The optical grade acrylic sheet is used to absorb the light emitted from the lamp to stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition by the light guide plate. The light is emitted from the front; the light guide plate can be made to emit...

Problems solved by technology

[0002] The light guide plate is made of optical-grade acrylic / PC sheet, and then the high-tech material with high reflectivity and non-absorbing light is used to print light-guiding points on the bottom surface of the optical-grade acrylic sheet with UV screen printing technology; The optical grade acrylic sheet is used to absorb the light emitted from the lamp to stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection condition by the light guide plate. The light is emitted from the front; the light guide plate can be made to emit light evenly through various light guide points of different densities and sizes; the purpose of the reflector is to reflect the light exposed on the bottom surface back into the light guide plate to improve the efficiency of light use; the existing The structure of the light guide plate production equipment is complicated, and the production process is complicated, resulting in low production efficiency
