Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary product production equipment, in particular to a scrap material recovery device. Background Art

[0002] During the production process of sanitary napkins, a large amount of scraps will be generated. These scraps are made of high molecular polymers such as cotton, non-woven fabrics, pulp or composites of the above materials. From a production perspective, these scraps need to be recycled and reused. The current common scrap recycling device is to manually collect them at regular intervals next to the sanitary napkin production cutting line. However, there is also a problem, that is, the quality problem. The core of this model is to collect scraps that fall on the ground. At this time, there is a problem of damage to the scrap materials. Even after collection, they must be cleaned before they can be reused, which is no longer economical.

[0003] Chinese patent application No. 202323106258.8 discloses a scrap recovery device for sanitary napkin production, comprising guide plates on both sides of a sanitary napkin production and cutting assembly line and scrap recovery components symmetrically arranged on the outside of the guide plates; the scrap recovery component comprises a mounting groove, a collecting cylinder connected to the mounting groove and a collecting box detachably connected to the collecting cylinder, the sanitary napkin production and cutting assembly line is arranged in the mounting groove, the mounting groove is located above the sanitary napkin production and cutting assembly line and is provided with a scrap blowing component, a scrap crushing component is provided between the mounting groove and the guide plate; a fan for stirring and flying scraps is provided below the sanitary napkin production and cutting assembly line, the collecting cylinder is used to collect scattered scraps after free fall, the bottom of the collecting cylinder is provided with a compression component for compressing and integrating scattered scraps, and an electrically controlled switch valve is provided at the connection between the collecting box and the bottom of the collecting cylinder. The recycling device is directly designed based on the sanitary napkin production and cutting assembly line. The scraps generated after the sanitary napkins are cut by the sanitary napkin production and cutting assembly line are directly collected by this device, which can fundamentally solve the problem that the traditional manual collection of scraps easily makes the scraps dirty and no longer economical when reused.

[0004] In addition, the recycling device uses a compression component to compress and integrate the scattered scraps. Although it can effectively compress the volume of the scraps, the compressed scraps are difficult to classify and are not convenient to use. The traditional recycling device collects the scraps directly in the collection box and then transfers them through negative pressure adsorption. This method requires the equipment to be shut down to completely clean the scraps in the collection box, which greatly affects production efficiency. Utility Model Content
