The working principle of the utility model is that the release paper is crushed into scraps, and the scraps of the release paper are removed fromFeeding inThe material port 61 enters the heating screw conveyor 6 for heating, the spiral pushing plate pushes the release paper scraps forward, the heating screw conveyor 6 heats the release paper scraps to more than 95 ℃ so that the adhesive layer is softened and easy to adsorb and peel, and then the release paper scraps are pushed to the material outlet 62 and fall into the material outletWithin the holding tank 26. The heating screw conveyor 6 controls the time for which the paper scraps stay inside the heating screw conveyor 6 by adjusting the conveying speed of the screw plate, thereby realizing the control of the temperature of the discharge port 62.

The conveying roller 20 is a negative pressure roller, a plurality of adsorption holes 2512 are formed on the surface of the conveying roller 20, the negative pressure fan 41 continuously pumps out air in the second stripping roller 22 and the conveying roller 20, negative pressure is formed in the second stripping roller 22 and the conveying roller 20, and the adsorption holes 2512 adsorb release paper on the surface of the conveying roller 20 under the action of the negative pressure.

The suction holes 2512 suck the heated release paper by negative pressure, and the release paper rotates clockwise following the transfer drum 20. The release paper rotates along with the conveying roller 20 and passes through the limiting block 8, a crack is formed between the limiting block 8 and the outer side of the conveying roller 20, and the limiting block 8 on the side surface of the conveying roller 20 scrapes off the release paper which is sticky and redundant, so that the surface of the conveying roller 20 adsorbs the single-layer release paper. The release paper adsorbed at this time has two states, the first state: the paper layer is adsorbed on the surface of the transfer roller 20, the adhesive layer is on the outer side, and the second state: the glue layer is adsorbed on the surface of the transfer drum 20, the paper layer being on the outside.

The release paper follows the transfer cylinder 20 and passes through the first stripping cylinder 21. The first stripping roller 21 is a normal pressure roller, the adhesive surface of the release paper in the first state is adhered to the first stripping roller 21, the first stripping roller 21 brings the adhesive layer away from the surface of the conveying roller 20, the adhesive layer is transferred to the surface of the first stripping roller 21, the adhesive layer rotates anticlockwise along with the first stripping roller 21, the adhesive layer is removed by the first scraper 231 on the left side of the first stripping roller 21 and falls on the surface of the first conveying belt 71 below the first scraper 231, and the first conveying belt 71 conveys the adhesive layer into the first collecting groove 74 to complete collection. Due to the negative pressure of the second stripper roller 22, the glue layer is also sucked onto the surface of the transfer roller 20 and continues to follow the transfer roller 20. At this time, the transfer drum 20 has the remaining paper layer of the first state release paper and the second state release paper left.

The release paper follows the transfer cylinder 20 and passes over the second stripping cylinder 22. The second stripping roller 22 is a negative pressure roller, and the suction holes 2512 on the surface of the second stripping roller 22 simultaneously suck the remaining paper layer of the release paper in the first state and the paper layer of the release paper in the second state, and the remaining adhesive layer remains on the surface of the transfer roller 20. The paper layer adsorbed on the surface of the second stripping roller 22 is removed by a second scraper 232 on the right side of the second stripping roller 22, and falls onto the surface of a second conveyor belt 72, and the second conveyor belt 72 conveys the paper layer to a second collecting tank 75 to complete collection.

After the above steps, only the adhesive layer left on the release paper in the second state remains on the surface of the transfer roller 20, and the adhesive layer continues to rotate along with the transfer roller 20. Because the glue layer is in a softened state and has a certain viscosity, the adsorption holes 2512 of the conveying roller 20 are easily blocked by the softened glue layer, and the air gun 52 arranged in the conveying roller 20 can blow out the glue layer in the adsorption holes 2512 and remove the glue layer by the third scraper 233 on the right side of the conveying roller 20, the glue layer falls on the surface of the third conveying belt 73, and the third conveying belt 73 conveys the glue layer to the third collecting tank 76 to complete collection.
