Description

Technical Field

[0001] The utility model relates to the technical field of waste paper packaging equipment, in particular to a waste paper packaging machine. Background Art

[0002] Waste paper refers to recyclable and renewable resources that are discarded after use in production and life, including various high-grade papers, yellow cardboard, waste cardboard boxes, trimmed paper, packing paper, paper for enterprises and units, engineering paper, books, periodicals and newspapers, etc. It also includes the scraps generated during the manufacture of paper products. When the waste paper is processed uniformly, it needs to be packaged to reduce the volume, and thus a waste paper baler is needed.

[0003] In order to improve the efficiency of waste paper packaging, the prior art has made many improvements to the waste paper packaging machine. For example, the patent with patent publication number CN219903488U discloses a waste paper packaging machine, including a base, a side plate is fixed on the upper end surface of the base, two front-to-back symmetrical movable plates are arranged on the left side of the side plate, two front-to-back symmetrical guide grooves are arranged in the base, and two left-to-right symmetrical guide wheels are arranged in the two guide grooves. The utility model pushes the push plate to move rightward by the first cylinder, so that the two movable plates are inserted into the grooves in the side plates, so that they form a closed rectangle, and then the second cylinder is used to push the pressing plate downward to squeeze the waste paper in the rectangle and compress it into a cube. After the compression is completed, the first cylinder is contracted to make the push plate drive the two movable plates to move leftward. In this process, the two movable plates move away from each other, so that they are out of contact with the waste paper bag, thereby facilitating the removal of the waste paper bag and avoiding the friction between the movable plate and the waste paper bag causing the waste paper bag to be dispersed again.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] In the above-mentioned comparative document, the second cylinder drives the pressure plate to move downward, and the pressure plate squeezes the waste paper in the rectangle. However, in actual operation, during the compression process of a lot of waste paper, the friction between the waste paper will gradually increase. Compressing the waste paper in the rectangle by only one direction force will result in incomplete compaction between the waste paper. When the waste paper needs to be compacted, it is necessary to reduce the amount of waste paper that needs to be compacted each time. During operation, the waste paper is put into the rectangle in batches and in small quantities. The operation is repeated, thereby reducing the efficiency of packing the waste paper. Therefore, there is an urgent need in the art to improve the waste paper baler to solve the defects of the prior art. Utility Model Content
