[0041] Principle and operation process

[0042] The utility model adopts a controller to control each component, and by adding a cutting mechanism, the traditional process of cutting the sling separately is omitted, and the operation is directly performed during the sewing process. The specific operation is as follows: before use, the unwinding roller 21 is removed, the woven bag roll is placed on the unwinding roller 21, and then the unwinding roller 21 is installed, one end of the woven bag roll is passed between the conveying shaft 10 and the driven shaft 101, and the woven bag to be sewn with the sling is placed on the second frame 13, and the sewing work is started. The woven bag is positioned, and the first cylinder 92 is started to press the woven bag. Since the bottom surface of the tooth plate is provided with an anti-skid protrusion 91, it can play a good anti-skid role and prevent the woven bag from slipping during the movement. At the same time as the first cylinder 92 is started, the reducer 102 is started to convey the woven bag roll. After conveying to a suitable length, the reducer 102 is turned off, and the electric sewing machine 12 is started to start sewing. The program will be input into the controller to control the first servo motor 41 and the second servo motor 7 1 is started and stopped, thereby realizing automatic sewing work. After the sewing of one end of the sling is completed, the first cylinder 92 retracts, and the reducer 102 is started again to convey the woven bag roll of the required length. After reaching the appropriate length, the reducer 102 is turned off and the second cylinder 114 is started at the same time. The second cylinder 114 pushes the hinge of the scissors 113 to move away from the second cylinder 114, and the cylindrical limit block connected to the handle of the scissors 113 will move in the arc-shaped slide groove 81. Since the slide groove 81 is arc-shaped, the two blades of the scissors 113 will gradually close with the push of the second cylinder 114 to complete the cutting operation. At this time, the sling as a whole will be separated from the woven bag roll, and the operator will put the woven bag until it is suitable, adjust the position of the other end of the sling, start the first cylinder 92, and the pressing plate 9 presses the woven bag. The controller controls the first servo motor 41 and the second servo motor 71 to sew again to complete the sewing work of a sling. Repeating the above operations can complete continuous operation.

[0043] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
