Description

Technical Field

[0001] This application relates to the technical field of printing production, and in particular to a printing waste paper collection and treatment device. Background Art

[0002] Printing equipment refers to the machinery that processes and finishes the printed sheets into printed products. There are three methods for binding books and periodicals: thread binding, paperback binding, and hardcover binding. Generally, the processes such as cutting, folding, gathering (collating), book block processing, stapling, covering, trimming, and packaging are involved. The machinery, equipment, and instruments used in the production of printed materials and the completion of the printing process are collectively referred to as printing equipment; it is generally divided into three categories: plate-making machinery, printing presses, and binding machinery. In addition, pad printers and screen printers used for printing stationery and electronic products are also widely used.

[0003] During the printing production process, a paper cutter is needed to cut the paper into the required size. After cutting, a large amount of paper edges and other residual corner pieces of paper are generated. There is no dedicated collection equipment for these printing waste papers. Therefore, the demand for waste paper collection devices for printing equipment is increasing day by day.

[0004] The existing methods for collecting and treating waste paper are generally to place it beside the paper cutter by the staff. When the printing waste paper accumulates too much, the printing waste paper needs to be stuffed into a bag, then the printing waste paper is packed through the bag, and then transported out of the production workshop; or it is collected through a collection box and then centrally sent to the recycling location. These methods are not only inefficient but also the waste paper takes up a lot of space. Therefore, frequent operations are required, increasing the labor and transportation costs and reducing the recycling efficiency. Utility Model Content
