Description

Technical Field

[0001] The utility model relates to the field related to underwear production, in particular to a hot pressing device for underwear production. Background Art

[0002] Bra cup molds are divided into seamless cup molds, quilted bras and single-layer bras. The seamless cup mold is formed using special heat-setting equipment, and various sponge cups are supported by appropriate fibers such as polyamide fibers and synthetic elastic fibers. If transparent or flesh-colored thin fabrics are heat-pressed together with seamless mold cups, a product equivalent to an "invisible bra" can be formed. The quilted bra first heat-presses the fluffy cotton into a certain thickness and sticks it between two layers of knitted fabrics. The cotton cup is sewn into shape through changes in the cup cutting and the fixation of the lower edge steel ring, and then connected to other parts. The bra cup mold needs to be heat-pressed and formed by a hot pressing device before subsequent processing.

[0003] The Chinese patent document with publication number CN216998896U discloses a hot pressing device for underwear production, which cuts the fabric after hot pressing by arranging a cutting knife on the upper pressing mechanism, replacing manual secondary cutting, reducing the process, reducing labor, and improving work efficiency. The scraps after cutting are collected by arranging a reel, avoiding manual collection of scraps separately, thus reducing labor;

[0004] Although the original equipment can heat the product raw materials by pressurizing them, the hot air generated during the heating process can easily diffuse in the production environment, making the environment too hot and stuffy and causing discomfort to the workers. Improvements have been made. In addition, as the hot air is lost in the environment and not utilized, it is also a waste of energy. Utility Model Content
