Description

Technical Field

[0001] The present application relates to the technical field of recycled paper production, and in particular to a recycled paper production process. Background Art

[0002] Recycled paper is mainly made from waste paper, plastic bags and other raw materials through a series of processing techniques, realizing the recycling and reuse of waste paper, plastic bags and other raw materials.

[0003] The process of extending recycled materials is generally to separate the collected waste paper and plastic bags into pulp raw materials through a paper-plastic separator, and then send the separated pulp raw materials into a pulp pool for stirring and breaking up to form pulp, and then filter it, and transmit the filtered pulp through a conveying mesh cage and a transfer blanket, and reel it up through a paper receiving roller. When the paper roll collected by the paper receiving roller reaches a certain thickness, the paper roll is cut and removed from the reel, and finally the removed paper roll is laid flat for drying and drying.

[0004] In the prior art, the Chinese patent application number CN200510019553.2 discloses a method for collecting recycled paper materials, which relies on a conveying mesh cage to convey the coarse pulp to the transfer blanket, and the transfer blanket circulates around the conveying platform to drive the pulp to the paper collection roller, and repeatedly wraps, squeezes and thickens on the paper collection roller to obtain a recycled paper pulp board. When a recycled paper pulp board of corresponding thickness is obtained, the winding can be stopped, and two people use their hands to take out the two ends of the elastic line from the side of the paper collection roller and pull it outward. Because the newly wound recycled paper pulp board still contains a certain amount of moisture, the elastic line can smoothly cut the recycled paper pulp board, and the removed recycled paper pulp board is then dried to eliminate excess moisture to obtain a finished product.

[0005] Since the paper material wound on the paper receiving roller still has a certain amount of moisture, when separating the paper material on the paper receiving roller, the paper material is easy to adhere to the winding roller, making it inconvenient for the staff to remove the pulp from the winding roller.

[0035] Reference Figure 5When the cutting knife 10 is completely received in the receiving groove 11, the two sliding plates 18 move to the locking block 16 and insert into the locking groove 23 under the action of the spring 19, and the connecting plate 15 is in a locked state at this time; when the cutting knife 10 extends out of the receiving groove 11, the cutting knife 10 slides open the two sliding plates 18 and the locking block 16 disengages from the locking groove 23, and the connecting plate 15 is in an unlocked state at this time.

[0036] The implementation principle of a recycled paper production process in the present application embodiment is as follows: When the paper on the winding roller 1 is wound to the required thickness, the winding roller 1 is controlled to rotate to the position where the cutting blade 10 faces upward, and then the cylinder 13 controls the cutting blade 10 to extend out of the storage slot 11, and in the process of extending, the sliding plate 18 is slid open to make the locking block 16 disengage from the locking slot 23, and the paper wound on the winding roller 1 is cut off at the same time. When the paper is cut off, the flexible plate 2 is flattened under the action of its own elastic force, and the paper on the flexible plate 2 is flattened accordingly. At this time, when the flattened flexible plate 2 is bent toward the surface of the winding roller 1 again, air passes through the air holes 9 on the flexible plate 2, making it difficult for the paper to be attached to the flexible plate 2, which facilitates the removal of the paper on the winding roller 1.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
