[0044] A guide tail plate 12 is set at the rear end of the support 1. Several food bags 7 connected together by a series operation slide down from the guide tail plate 12 into the next production node.

[0045] A first slot 201 is opened on the lower pressing conveyor belt 20 so that after the connecting strip 50 is placed on the upper surface of the lower connecting bag tape 40, the connecting strip 50 is embedded in the first slot 201, so that the connecting strip 50 is firmly connected to the lower connecting bag tape 40. Furthermore, the connecting strip 50 is limited by cooperating with the first slot 201 to prevent the connecting strip 50 from falling off the lower pressing conveyor belt 20.

[0046] A second slot 301 is opened in the middle of the outer surface of the upper pressing conveyor belt 30. The connecting strip 50 is embedded in the second slot 301. At the gap between adjacent food bags 7, the connecting strip 50 is firmly connected to the upper connecting tape 60. Furthermore, the connecting strip 50 is limited by the cooperation between the connecting strip 50 and the second slot 301 to prevent the connecting strip 50 from falling off the upper pressing conveyor belt 30.

[0047] The food bag stringing device in this embodiment operates as follows: The output shaft of motor 81 rotates, driving the lower drive pulley 21 and the upper drive pulley 31 to rotate, which in turn drives the lower pressing conveyor belt 20 and the upper pressing conveyor belt 30 to run. The lower connecting bag tape assembly 4 conveys the lower connecting bag tape 40 to the upper surface of the lower pressing conveyor belt 20, and the connecting bag strip assembly 5 places the connecting bag strip 50 on the upper surface of the lower connecting bag tape 40. The food bags 7 are arranged in the order of cooking and added, and are sequentially conveyed to the upper surface of the lower pressing conveyor belt 20.
