Description

[0001] This invention is a divisional application of "Automatic Folding, Packaging and Conveying Device for Surgical Towels and Crepe Paper and its Usage Method" (Application No.: 2023100388444; Application Date: 2023-01-13). Technical Field

[0002] This invention relates to the technical field of medical surgical drape crepe paper processing and production equipment, and in particular to an automatic folding, pressing, and conveying method for surgical drape crepe paper. Background Technology

[0003] Surgical drapes are one of the most basic consumables in medical surgery. Generally, disposable surgical drapes can be divided into two types: sterile and ordinary. The main difference is that sterile surgical drapes contain X-ray detection lines or detector strips.

[0004] As the most basic surgical consumables, the demand for surgical drapes is huge. Currently, surgical drapes are mainly produced through fully automated production lines. However, after the surgical drapes are manufactured, they need to be folded and stacked for easy packaging and use. The existing folding method relies on manual labor. The huge output means huge labor consumption, and folding surgical drapes for a long time is very tedious. Operators often lose focus. The longer the working time, the worse the folding quality becomes. Compared with automated production lines, this method is inefficient and costly. Summary of the Invention

[0005] The technical problem this invention aims to solve is to provide an automatic folding, pressing, and conveying method for surgical drapes and crepe paper. This method utilizes multiple interconnected conveyor belts to achieve frequent folding and turning during continuous transport of the surgical drapes and crepe paper. Multiple folds meet packaging requirements, resulting in a high degree of automation and stable processing. During the folding and conveying process, elastic feeding and compaction ensure that each fold of the surgical drapes and crepe paper is uniformly compacted and pressed during transport, resulting in precise and stable folding connections and significantly improving material folding and stacking efficiency. The overall structure of the device can be flexibly adapted to the inlet and outlet ports of multiple processes in the production line, allowing for flexible and convenient connections and greatly enhancing the automation level of the production line.

Step 2: The folded surgical drape crepe material is pressed to the discharge end of the second conveyor belt and clamped by the guide plate and the third conveyor belt. Step 3: When the folded surgical towel crepe paper material is conveyed to the middle position and overlaps with the second folding push plate, the second electric push rod works and is folded and fed into the feed end of the fourth conveyor belt under the push of the second folding push plate.
