Description

Technical Field

[0001] This utility model relates to the field of waste paper recycling technology, and in particular to a waste paper baler. Background Technology

[0002] With economic and social development, paper consumption has increased rapidly, resulting in a large amount of waste paper. Waste paper refers to recyclable resources discarded after use in production and daily life, including various high-grade papers, corrugated cardboard, waste paper boxes, trimmed paper, baling paper, corporate paper, engineering paper, and books and newspapers. Large amounts of waste paper, after recycling, accumulate, occupying a large area and making transportation inconvenient. Waste paper balers compress waste paper into a six-sided cube shape, saving space and facilitating stacking and transportation. A typical waste paper baler consists of a frame with a compression box at the bottom and a hydraulic cylinder at the top. The cylinder drives a pressure plate to move up and down. After waste paper is placed in the compression box, the cylinder drives the pressure plate to compress the waste paper downwards, forming a cube. After compression, the front door of the compression box is opened, and the compressed waste paper cube is removed and bundled. The front door of the compression box is mostly hinged. After the front door is closed, it is locked by a locking device. When the pressure plate squeezes into the compression box, the paper in the compression box will exert pressure on all sides. Therefore, the normal load on the compression box is also relatively large. The load on the front door of the compression box will be transmitted to the hinge and locking device of the front door. These two points are movable connections, and the cross-sectional thickness of the connection is small. Long-term load can easily cause deformation, affecting the normal opening, closing and locking operation of the front door of the compression box. Therefore, a way to avoid deformation at the hinge of the front door is needed. Utility Model Content
