On wheel carrier;If the dry slide 21 is matched with roller frame basal sliding.By being equipped with level(l)ing mechanism below two roller frames,
It is conveniently adjusted the relative position of two rolling surface of light guide plate.
The hot rolling process of light guide plate based on light guide plate hot-rolling pressing production line, (1) leaded light board raw material are extruded into through extruder
Plate temperature after type is 200-240 degree, after communicated device is cooled to 30-60 degree, into rolling device;(2) plate is successively
By roll-in between the first roller 1 and the second roller 2 of two groups of processing rollers, two groups of processing rollers are equipped with the first of micro-structure
Roller 1 and the second roller 2 form micro-structure to two plate face roll-ins of plate respectively;It (3) is blocky light guide plate by plate cutting.
Wherein, Optimal Temperature is 45 degree when light guide plate enters rolling device from transmission device.
The step (2) includes the following contents: by heating device to 1/ second roller of the first roller for being equipped with lattice point structure
2 heating of wheel, and first roller 1 of two processing roller sets and the rotary electric machine of the second roller 2 are opened, plate passes through two groups of processing
Upper face, lower face are successively processed between the first roller 1 and the second roller 2 of roller.
Light guide panel material is acrylic, and cutting equipment used in step (3) is laser cutting machine.Extruder one side ejecting plate
Rolling device carries out roll-in site on one side, plants after having pressed in the datum mark of setting automatically and is cut to several plates, improves plate
Anti-shear performance and optics net-point quality.Datum mark is set by the light guide plate of different size specification.The of two groups of roll-in rollers
The roller length of one roller 1 and the second roller 2 be 6 meters~18 meters, roller diameter be 2 meters~6 meters, oil temperature machine temperature be 50~
160 degree, the revolving speed of rotary electric machine is 0.5 meter per minute~5 meters.
Before light guide plate carries out roll-in, by extruder hot briquetting, temperature is about 220 degree at this time, communicated drop
Wen Hou, since plate stress has been discharged in stable state, compared to directly being carried out for roll-in after discharging, lattice point structure
Unanimously, the optical property with the uniformity of light guide plate are higher.Roll-in site is used for by what two groups of processing rollers were staggered above and below
The first roller 1 and the second roller 2 successively light guide plate plate upper face and lower face are processed.Then according to 1 He of the first roller
The datum mark of second roller, 2 roll-in is cut into the light guide plate of different size, then is processed by shot blasting.By form, transmit cooling,
The process of upper and lower plate face successively roll-in, cutting, keeps light guide panel material more stable and discharges stress, improve the optical property of plate with
The uniformity of lattice point structure processing.
