Abstract
Description
Technical Field
[0001] The invention relates to the technical field of meltblown waste, and in particular to a feed flow rate regulating mechanism for meltblown waste recycling. Background Art
[0002] Meltblown waste refers to the waste generated during the production of meltblown cloth. Its main components include polymer materials such as polypropylene and polyester. These wastes have good strength and wear resistance, and also have waterproof, breathable and filtering properties. The reuse of meltblown waste is melting regeneration: the meltblown waste is heated and melted, and then processed into new meltblown cloth or other plastic products through molding, stretching and other processes. Recycling: the meltblown waste is sorted, cleaned, crushed and other treatments, and then used to produce some low-end plastic products or filling materials. In the process of meltblown waste recycling, a feed flow rate regulating mechanism for meltblown waste recycling is required.
[0003] In this regard, China has applied for a patent number: CN118579547A, which discloses a rice feed flow rate regulating mechanism, including: a feed flow rate regulator, a feed transfer chamber is formed between two adjacent partitions on the feed flow rate regulator and the outer wall of the linkage tube, and a feed transfer chamber space regulating mechanism is arranged on the inner side of each feed transfer chamber. When the feed transfer chamber space regulating mechanism moves between the two partitions, the size of the containing space of the interlayer between the two partitions can be adjusted, so that the rice feeding flow rate can be adjusted. In the present invention, the rice feeding rate can also be further adjusted by changing the rotation rate of the motor output shaft. While changing the rotation rate of the motor output shaft, the transmission efficiency of the transmission mechanism can also be changed.
