Description

Technical Field

[0001] This utility model relates to the field of button fastening technology, and in particular to a button fastening device for clothing. Background Technology

[0002] Button sewing is an important part of the garment production process. In traditional garment processing, button sewing relies on manual operation, which is labor-intensive for workers, has low production efficiency, and makes it difficult to guarantee the accuracy and consistency of the sewing position.

[0003] With the development of automation technology, semi-automatic button sewing equipment has emerged on the market. Although these devices have improved the efficiency of the sewing action to some extent, there are still obvious shortcomings in the button supply process. Many devices require manual placement of buttons one by one into the designated position of the sewing mechanism. This feeding process interrupts the continuous workflow of the equipment and becomes a bottleneck restricting the overall production efficiency. A lot of effort is required for repetitive feeding and posture adjustment, which not only fails to reduce labor intensity but also greatly reduces the automation level of the equipment.

[0004] To solve the feeding problem, some solutions have introduced automatic feeding systems. However, existing feeding systems are unable to solve the problem of automatically screening the button posture. Buttons have a front and a back, and they must enter the fastening mechanism in the correct posture to complete the effective fastening. If the feeding system cannot automatically and reliably screen and correct the button posture, it will lead to a high fastening failure rate, or even damage to equipment or clothing, and will not be able to achieve stable and reliable automated production. Existing technology lacks a structural solution that can efficiently and continuously integrate the automatic screening and precise orientation of buttons with the subsequent fastening action.

[0005] Therefore, this utility model proposes a garment button fastening device to overcome the shortcomings of the prior art. Utility Model Content
