The bag-opening drive cylinder 82 consists of a first bag-opening cylinder and a second bag-opening cylinder connected via a bag-opening cylinder fixing plate. The first bag-opening cylinder's drive rod is rotatably mounted on the bag-opening mounting frame 78 via a first bag-opening cylinder joint 83. The second bag-opening cylinder's drive rod is rotatably connected to a first connecting rod 85 and a second connecting rod 86 via a first rotating shaft 84. The other end of the first connecting rod 85 is connected to the bag-opening mounting frame 78, while the other end of the second connecting rod 86 is connected to the sixth slide rail 80.

[0067] The driving rod of the bag-opening driving cylinder 82 extends, driving the first connecting rod 85 and the second connecting rod 86 to rotate about the first rotating shaft 84. The other end of the first connecting rod 85 moves away from the other end of the second connecting rod 86, and the third mounting plate 77 moves downward along the sixth slide rail 80. The driving rod of the bag-opening driving cylinder 82 retracts, and the other end of the first connecting rod 85 moves toward the other end of the second connecting rod 86, and the third mounting plate 77 moves upward along the sixth slide rail 80.

[0068] The upper end of the bag clamping and moving base 69 has an inwardly extending extension 69c. This extension 69c houses a fourth pneumatic cylinder 87, which drives the bag opening mounting frame 78 forward and backward. The extension 69c houses a mounting frame connecting plate 79, the underside of which is fixedly mounted a seventh slide rail 88. A seventh slider, which engages with the seventh slide rail 88, is mounted on the extension 69c. The cylinder body of the fourth pneumatic cylinder 87 is mounted on the extension 69c, and the drive rod of the fourth pneumatic cylinder 87 is connected to the seventh slide rail 88 via a fourth pneumatic cylinder 87 connector. When the drive rod of the fourth pneumatic cylinder 87 extends, the seventh slide rail 88 moves forward relative to the seventh slider, and the mounting frame connecting plate 79, which is fixed to the seventh slide rail 88, moves forward, causing the bag opening mounting frame 78 to move forward. When the drive rod of the fourth pneumatic cylinder 87 retracts, the seventh slide rail 88 moves backward relative to the seventh slider, causing the bag opening mounting frame 78 to move backward.

[0069] After the bag is flattened on the rear end of the support frame 61, the second conveyor motor 74 drives the bag clamping movable seat 69 toward the rear end of the support frame 61 until it stops at the leading end of the bag. The third suction cup 62 on the third suction cup mounting seat 63 grasps the lower surface of the bag's leading end. The bag opening drive cylinder 82 moves downward, and the fourth and fifth suction cups 64 and 66 on the third mounting plate 77 approach the bag. They grasp the upper surface of the bag's leading end, thus clamping the flat bag.

[0070] The second transfer motor 74 drives the bag clamping moving seat 69 to move towards the front end of the material supporting frame 61, and the fourth cylinder 87 drives the bag opening mounting frame 78 to continue moving forward. The bag material moves from the rear end of the material supporting frame 61 to the front end of the material supporting frame 61. The bag opening driving cylinder 82 drives the third mounting plate 77 to move upward. The fourth suction cup 64 and the fifth suction cup 66 on the third mounting plate 77 drive the upper surface of the bag material to move upward, realizing the opening of the flat pocket. The clothing is loaded into the flat pocket, and the third suction cup 62, the fourth suction cup 64 and the fifth suction cup 66 release the bag material. The flat pocket is closed and waits for the feeding device in front of the material supporting frame 61 to transfer the flat pocket from the front end of the material supporting frame 61 to the packing place.

A baffle 114 for pressing the label belt is provided at the outlet of the label belt pulley 112 for outputting the label belt. The baffle 114 is in a "V" shape. The included angle of the baffle 114 is rotatably installed on the front side of the labeling vertical plate 111 through the third rotating shaft 115. One end of the baffle 114 abuts against the label belt pulley 112, and the other end of the baffle 114 has a fifth connecting portion 114a extending downward. An adjustment groove 111a is provided on the labeling vertical plate 111, and the adjustment groove 111a is located below the label belt pulley 112. A tension spring 116 is provided in front of the labeling vertical plate 111. One end of the tension spring 116 is installed in the adjustment groove 111a through the tension spring 116 mounting rod 63a, and the other end of the tension spring 116 is connected to the fifth connecting portion 114a of the baffle 114. The tension spring 116 can elastically pull the baffle 114, so that the baffle 114 can always press the label belt and prevent the label belt pulley 112 from rolling out the excess label belt.

[0082] A first runner 117, a second runner 118, and a fixed seat 119 are also provided on the front side of the labeling vertical plate 111. The label belt sequentially passes through the lower arc of the first runner 117, the upper arc of the second runner 118, and the lower surface of the bottom plate of the fixed seat 119. A second air blowing pipe 120 is provided below the fixed seat 119.

The other end of the transmission block 129 is connected to the driving rod of the seventh cylinder 130 through the joint of the seventh cylinder 130. When the driving rod of the seventh cylinder 130 contracts, it drives the transmission block 129 to rotate. The transmission block 129 drives the fourth rotating shaft 122 to rotate, and the fourth rotating shaft 122 drives the label clamping seat 121 to approach the fixed seat 119. The label clamping block 125 rotates above the label clamping groove 119a, and the fifth cylinder 124 drives the label clamping block 125 to clamp the label. When the driving rod of the seventh cylinder 130 extends, the label clamping seat 121 rotates around the fourth rotating shaft 122, and the label clamping block 125 clamps the label and pulls out a section of label tape.

[0086] There is a cutter 131 for cutting the label tape on the front side of the labeling vertical plate 111. The cutter 131 is located on one side of the fixed seat 119.
