Description

Technical Field

[0001] The present invention relates to the technical field of earmuff production equipment, and in particular to an earmuff production line. Background Art

[0002] Headphones are a common daily necessity, effectively blocking out external noise while ensuring your music doesn't disturb others. There are many different types of headphones on the market, including earbuds, over-ear headphones, and headphones. Headphones typically come with earmuffs for increased comfort.

[0003] Existing earmuffs for headphones generally consist of a cover, a first plastic part, a second plastic part, and a mesh (the first plastic part is a large ring-shaped TPU, and the second plastic part is a small circular TPU). The production and processing of the earmuffs usually includes processes such as forming the cover, welding the first plastic part to the cover, welding the second plastic part to the cover, and welding the mesh to the second plastic part. Each process requires manual loading and unloading of materials. For example, after the cover is formed, the formed cover and the first plastic part need to be placed in a welding machine for welding. The welded cover and the first plastic part are then removed and transferred to the next process. This operation is repeated until the earmuff is completed. Therefore, the existing earmuff production has a low degree of automation, is time-consuming and labor-intensive, and has low production efficiency, which is not conducive to the smooth progress of earmuff production operations.
