Technical Field

The invention relates to the technical field of recycling of a partition plate, and particularly belongs to a recycling processing method of a polaroid edging partition plate.

Background

POL is a polarizer, which is called a polarizer, the imaging of the liquid crystal display must depend on polarized light, and all liquid crystals have front and back polarizers which are tightly attached to the liquid crystal glass to form the liquid crystal plate with the total thickness of about 1 mm. If any one of the polarizers is omitted, the liquid crystal sheet cannot display images. Because POL is soft and easy to deform and bump, PS (polystyrene) partition plates (with the thickness of 0.1-1mm and the common thickness of 0.1-0.3mm) are needed to be padded on the uppermost layer and the lowermost layer of the whole POL stack to play the roles of supporting and protecting; the cutter discs rotating at high speed at the two sides of the equipment are arranged, and reasonable grinding amount, pressure and feeding speed are set, so that the peripheral end faces of the stacked POLs are ground, and the required size and angle accuracy is achieved.

With the continuous development of the POL field, gradually advancing the production size of the POL from a medium size (1.6-21 inches) to a large size (23-50 inches), and with the gradual increase of the demand of production for the PS partition plates, the PS partition plates occupy a large amount of manufacturing cost; according to POLs with different sizes, a purchasing department needs to purchase new PS partition boards with different specifications, and after the new PS partition boards are used up, the new PS partition boards are treated as waste products due to broken filaments, sawteeth and foreign matters on the edges of the PS partition boards, so that partition board resources are seriously wasted.

The existing treatment method comprises the steps that 3-5 used PS partition plates are stacked, four sides of the used PS partition plates are adhered by masking tape and fixed on a PP (polypropylene) cushion plate, the peripheries of the used PS partition plates are cut off by a straight long knife according to the required specification, and the partition plates needed in the middle are reserved; the baffle that comes out uses 200 to fold again, sends to clean station, and personnel use dustless cloth and alcohol to clean its upper and lower surface, picks out marginal defective baffle in step, sends the yields to the edging at last and carries out the secondary use, and the operating efficiency of this method is lower, and the cost is higher, and the baffle size precision of making, right angle precision are relatively poor, leads to whole pile of POL untidy easily during the secondary use (as shown in fig. 3 and 4), and then leads to the POL right angle super rule after the processing.
