Description

Technical Field

[0001] This utility model relates to the field of hot air cotton drying technology, specifically a hot air cotton drying device. Background Technology

[0002] Hot air cotton, also known as "hot air bonded nonwoven fabric," is a subcategory of nonwoven fabric. The production process does not use chemical adhesives; instead, high-temperature hot air melts the fiber surface and bonds them together, avoiding the odor or potential irritation caused by adhesive residue. The fibers have a three-dimensional network structure with high loft, allowing them to store more air. Therefore, its warmth retention is superior to traditional cotton wadding of the same thickness. It is less prone to clumping and pilling, and has good moisture absorption and breathability. It also possesses a certain tensile strength and is highly durable.

[0003] Hot air insulation material, also known as non-adhesive insulation, is a new type of thermal insulation material that replaces spray-bonded insulation and imitation silk insulation. During production, hot air insulation requires drying to meet specific quality standards and performance requirements.

[0004] The existing technology has the following shortcomings: The existing technology, disclosed in CN217083224U, discloses a hot air drying device for nonwoven cotton fabric, which includes a box body. The two sides of the box body are provided with through grooves. The inner wall of the box body is provided with support plates on both sides of the through grooves, and hydraulic cylinders are installed on the support plates. The output end of the hydraulic cylinders is fixedly connected to a pressure plate through the support plate, and a pressure roller is installed on the pressure plate. The other side of the inner wall of the box body is provided with a fixing plate on both sides of the through groove, and an air outlet is installed on the fixing plate. Hot air blowers are installed on the top and bottom surfaces of the box body, and the hot air blowers are connected to the air outlets through air supply pipes.

[0005] While the aforementioned equipment is convenient for drying hot air cotton, it lacks a tension adjustment mechanism during the conveying process, making it difficult to keep the hot air cotton taut. This can easily affect the subsequent rapid drying effect, thus limiting its effectiveness in the drying process. Utility Model Content
