The input end of the driving motor 51 is electrically connected to the output end of the external power supply. The synchronous pulley 52 on the output shaft of the driving motor 51 drives the active sprocket 6 to rotate through the synchronous belt, and the active sprocket 6 drives the sprocket 15 in the chain tensioning device 1 to rotate through the conveying chain 4, thereby realizing the operation of this device. The work station positioning device 8 includes a positioning cylinder 81, and the positioning cylinder 81 is connected to the frame 2 through a fixed plate. The telescopic end of the positioning cylinder 81 is connected to the paper bag positioning plate 82. The end of the paper bag positioning plate 82 is a slope structure, and the paper bag positioning plate 82 corresponds to the positioning piece 32 in the clamping device 3. When the clamping device 3 clamps the handbag to the work station positioning device 8, the positioning cylinder 81 drives the paper bag positioning plate 82 to extend and retract. Due to the slope structure at the end of the paper bag positioning plate 82, The paper bag positioning plate 82 will exert a leftward force on the positioning member 32 during its movable and interlaced connection with the support shaft in the positioning member 32, thereby causing the positioning member 32 to drive the entire device to move to the left.

[0031] During use: the clamping device 3 is in the open and closed state when not clamping the handbag for transmission. First, assemble the appropriate clamping device 3 and work station as required, then adjust the position of the sprocket shaft 14 and the sprocket 15 through the tensioning screw 13 to achieve the tensioning of the conveyor chain 4, and then start the drive motor 51, and drive the conveyor chain 4 to rotate through the cooperation of the active sprocket 6 and the sprocket 15, thereby driving the rotation of the clamping device 3.

At the same time, the tension spring 37 allows the clamping claw 35 to still hold the handbag without loosening during the movement, and maintain the state unchanged. Then the conveying chain 4 moves the handbag conveyor belt to the position corresponding to the workstation positioning device 8. At this time, the positioning cylinder 81 drives the paper bag positioning plate 82 to be inserted and connected with the positioning member 32, which will give the positioning member 32 a leftward force, so that the positioning member 32 drives the entire device to move to the left. , so that each station is positioned based on the positioning piece 32, and then punched through an external device.

There are four sets of back plates 34 corresponding to the splint 310 and the connecting spring 311, corresponding to the four holes on the handbag. The rope inserted into the hole of the handbag is clamped by the splint 310 and does not loosen, and then sent to the bag loosening station. As above, the bag loosening cylinder 91 drives the push plate 93 to move through the cylinder head 92 , the push plate 93 drives the lower end of the main rocker arm 39 to move to the right, that is, the main rocker arm 39 drives the rocker arm 38 to move counterclockwise, so that the clamping jaw 35 moves outward along the guide shaft 36, thereby realizing the bag loosening action of the clamping jaw 35. When the clamping jaw 35 releases the handbag, all the actions of the handbag are completed. The design of the present invention is clever and takes up little space.
