Description

Technical Field

[0001] The present invention belongs to the technical field of gauze pad production, and particularly relates to an automatic folding and sewing production line for double gauze pads in one drag. Background Art

[0002] During the operation, doctors need to use medical abdominal pads (gauze pads) to wipe the blood on the surgical incision and surgical instruments to facilitate seeing clearly and performing the operation precisely. At the same time, the gauze pads are also used in the process of emergency hemostasis and suture hemostasis. Therefore, the demand for abdominal pads in hospitals is increasing year by year, and the production efficiency of manufacturers needs to be improved with the demand.

[0003] For example, Chinese Patent Application No. (CN202210041380.8) discloses an automatic folding and sewing production line for medical abdominal pads, including a feeding component, a feeding and cutting component, a docking feeding and discharging component, and a sewing component arranged in sequence. The automatic pipeline layout is adopted, which saves the labor input cost and ensures the processing yield. However, when the sewing component sews the gauze, it usually takes a long time. Therefore, the feeding component, the feeding and cutting component, and the docking feeding and discharging component pause for too long, and the production efficiency is not high.

[0004] Another example is Chinese Patent Application No. (CN202210063097.5) which discloses an abdominal pad processing device and its processing technology. By setting two groups of transfer components (docking feeding and discharging components) and two groups of sewing mechanisms (sewing components), the pause time of the feeding component, the feeding and cutting component, and the docking feeding and discharging component is reduced, effectively improving the production efficiency. However, the label feeding and processing mechanism of this application adopts the label placement device disclosed in Chinese Patent Application No. (CN202110236701.5), that is, the label feeding and processing mechanism in the prior art. And there is a situation where the gauze pad is left in the human body when it is used. Therefore, in order to facilitate detection, the label feeding and processing mechanism in the prior art usually sews an X-ray detectable light sheet (label), and X-ray detection is harmful to the body and needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic folding and sewing production line for double gauze pads in one drag to solve the above-mentioned existing technical problems, achieving the effects of high production efficiency, facilitating the detection of gauze pads left in the body, and not being harmful to the body.
