Overview:
The GK35-8A Double-Needle Fully Automatic Bag Sewing Machine (Bag Closing Machine) is equipped with a photoelectric sensor, pneumatic thread-cutting device, and controller. The photoelectric sensor and controller automatically control machine start/stop and thread-chain cutting. With a double-needle design, the machine sews two parallel lines in one operation, providing strong and reliable seams and helping achieve leak-resistant bag closure. It is especially suitable for manufacturers with strict bag-sealing requirements and can be used for closing paper bags, woven plastic bags, cloth bags, and other packaging bags. The controller also features bag counting and thread-chain length adjustment functions for convenient operation.
The machine is equipped with a newly designed controller that not only manages automatic start/stop and bag counting, but also allows the front and rear thread-chain lengths to be adjusted separately according to customer requirements. It is particularly suitable for sewing applications after crepe paper tape has been applied to the bag opening.
Operating Process:
Operating Process: The machine is installed on a conveyor. When a filled woven bag reaches approximately 10 cm from the sewing machine, the photoelectric sensor automatically starts the machine to sew the bag opening. After each bag is sewn, the cutter automatically cuts the thread chain and the sewing machine stops automatically.
