AI Technical Summary

Technical Problem

In the existing technology, the drawstring cutting speed of spunlace bags is slow and the efficiency of manual operation is low, which cannot meet the high-efficiency requirements of spunlace bag production lines.

Method used

Design a bag fabric drawstring hole puncher that includes a fixing block, a cylinder assembly, a connecting shaft, and a cutting assembly. The cylinder drives the connecting shaft to drive the cutter to automatically cut the drawstring hole during the conveying process. Combined with a clamping assembly, the fabric is prevented from moving, thus achieving automated cutting.

Benefits of technology

It enables rapid and precise cutting of the drawstring opening of spunlace bags, improving production efficiency, reducing manpower waste, and enhancing automation.

Abstract

The utility model discloses a hole puncher for a bag making cloth bundle rope opening. The hole puncher comprises a fixing block, a fixing column, an air cylinder assembly, a connecting shaft and a cutting assembly. The fixing block can be fixed to the workbench, a bag making cloth conveying channel parallel to the workbench face is formed in the fixing block, the two ends of the bag making cloth conveying channel are through, and a sliding through hole penetrating through the bag making cloth conveying channel is formed in the fixing block. The bottom end of the fixing column is vertically and fixedly connected with the upper end face of the fixing block. The cylinder assembly is fixedly connected with the top end of the fixed column, and a telescopic rod is arranged downwards; the first end of the connecting shaft is detachably connected with a telescopic rod of the air cylinder assembly. The cutting assembly comprises a column body and a cutter, the top end of the column body is fixedly connected with the second end of the connecting shaft, and the cutter is fixed to the bottom end of the column body; the column body penetrates through the sliding through hole in a sliding mode so that the cutter can cut the bag making cloth laid in the bag making cloth conveying channel. According to the hole puncher for the rope tying opening of the bag making cloth, the bag making cloth can be rapidly and automatically punched in the conveying process of the bag making cloth, and a large amount of manpower is saved.
