Generally, glass substrates used in the manufacture of flat panel displays, such as thin film transistor-liquid crystal displays (TFT-LCDs), plasma display panels (PDPs), and electro luminescent (EL), are adsorbed to each other when loaded. In order to prevent that from happening, an interlayer is interposed between glass substrates.

Such kanji is usually discarded, and the amount of kanji discharged from the display industry is huge, but recycling of such kanji is extremely insignificant. As a result, unrecycled slippers are landfilled with waste or incinerated, causing soil and air pollution.

Conventionally, there is a regeneration device for inserting a coil insert to recover and recycle the kanji, such a kanji regeneration device, as shown in Figure 1, the kanji winding motor 210 on one side of the pay-off reel (200) Positioned and rotatably mounted on the interleaver core 212 to the interleaver winding motor 210 and released on the interleaver core 212 by the interleaver winding motor 210 from the strip S. ) Is wound into a coil shape. And, if the middle portion is cut in the above process, the interlude P is attached with a temporary adhesive tape 215 and wound as an interleaver coil 220, and then withdraw the interleaver coil 220 to the interleaver regeneration facility ( After connecting to the interliner connecting portion sent to the forest paper adhesive tape (215) as an adhesive, and then wound by a coil of a diameter of a certain diameter while going through the ironing process and removing foreign matters on the surface of the slipper (P), It is to produce a sheet of paper and reuse it for each line process.

As described above, the regenerator of the conventional coil inserting slip sheet simply rewinds the rolled sheet from the coil and reuses it through the process of ironing the sheet and removing foreign substances on the surface of the sheet. The recycled paper recycled by this regeneration device is reused two to three times, after which it is eventually landfilled with waste or incinerated to generate soil and air pollution.

In addition, the pulp regenerator 300 using the interlayer paper for glass substrate according to the present invention, the operation of the automatic valve 303, the operation of the crushing screw 302, the operation of the water supply pipe 306, the rotary rod 308 Operation, operation of the air cylinder 310, operation of the first, second and third motors (302-1, 313, 314-1), operation of the heater, operation of the friction dryer 304 And a controller 250 that controls the operation of the vacuum pump blower 315-1.

Here, a vacuum pump blower 315-1 is mounted to the water tank 315 to discharge water from the pulp regeneration drum 305 to the water tank 315 through the discharge lake 309. In addition, the water supply pipe 306 is connected to the water tank 315, and the water supply pipe 306 is provided with a pump 316. Therefore, the water discharged to the water tank 315 through the discharge lake 309 is supplied to the water supply pipe 306 by the pump 316, the water is recycled.

Now, the operation of the pulp regenerator 300 using the interlayer paper for glass substrate according to the present invention will be described.

First, after the user operates the pulp regenerator 300 using the glass substrate interlayer paper, and puts the recovered interlayer paper into the hopper 301, a transfer screw that is mounted to the lower portion of the hopper 301 to crush and transfer the interlayer paper 302 is actuated by the first motor 302-1 according to the instructions of the controller 250 to primary break up the slip sheets.

Thereafter, the controller 250 opens the automatic valve 303 mounted on the supply pipe 304, so that the primary crushed slip sheet is drawn into the pulp regeneration drum 305, and by the operation of the controller 250. A certain amount of water is supplied from the water tank 315 through the water supply pipe 306. Thereafter, the second motor 313 mounted to the outside of the pulp regeneration drum 305 is operated by the operation of the controller 250, and the drive pulley connected to the second motor 313 by a belt or a chain ( By rotating the rotary rod 308 by the rotation of the 317, the pulping to separate the pulp from the velcro at the same time the secondary crushed mixed with water by the at least two blades 307 mounted to the rotating rod 308 This is done.

Here, the automatic valve 303 may be controlled to open and close the period by the controller 250, it is possible to increase or decrease the amount of the primary shredded slip paper introduced, the amount of the constant amount supplied by the water supply pipe to be described below Due to the mixing with water, the amount of pulp produced in the end can be reduced or increased. In addition, the shredding screw 302 first shred the slippers into 4-10mm, the blade 307 second shredded the first shredded slippers to 1-4mm. In addition, the rotating rod 308 is rotated by the second motor 313 at a rotational speed of 6 to 10 rpm for 3 minutes and then stopped for 30 seconds, and then repeats the cycle of reverse rotation for 1 minute to achieve a quiet and power saving effect. It can increase.

Thereafter, a vacuum pump blower 315-1 mounted to the water tank 315 is operated to discharge water from the secondary crushed mixture, and the vacuum pump blower 315-1 is operated to discharge the water through the discharge lake 309 connected to the upper portion of the pulp regeneration drum. Water is discharged to the water tank 315. At this time, by extracting about 80% of the water from the mixture, the mixture becomes a bamboo-like form of high wetness.

Here, when the discharge lake 309 is equipped with a fine sieve of less than 1mm to discharge water from the pulp regeneration drum 305 to the water tank 315 by the operation of the vacuum pump blower (315-1). To prevent the secondary shredded slips with water from escaping.

Thereafter, the bamboo mixture is moved to the drying unit 312 in which the heater is mounted by operating the air cylinder 310 by the controller 250. Here, the heater mounted on the drying unit 310 is heated to 250 ~ 300 ℃, thereby lowering the wetness of the mixture by heating the mixture.
