A sixth gear 110 is mounted on the right rack 109 and meshes with the right rack 109. The sixth gear 110 is rotatably connected to the upper right gripper 108. The drive rod of the right gripper drive cylinder 106 pushes the rack, which in turn drives the upper right gripper 108 on the sixth gear 110 to rotate.

[0075] The first feeding cylinder drives the fourth mounting plate 93 to the left. The left claw assembly on the fifth mounting plate 100 drives the upper left and lower left claw clamps to clamp the left edge of the bag. The right claw assembly on the sixth mounting plate 102 drives the upper right claw clamp 108 and lower right claw clamp 107 to clamp the right edge of the bag. The first feeding cylinder drives the bag to the right, delivers it to the packaging area, and then releases the bag.

[0076] In this embodiment, a group of left claw hand assemblies are installed on the fifth mounting plate 100, and three groups of right claw hand assemblies are installed on the sixth mounting plate 102. According to actual needs, the number of left claw hand assemblies on the fifth mounting plate 100 can be one to three groups, and the number of right claw hand assemblies on the sixth mounting plate 102 can be one to three groups.

[0077] The feeding device can also drive the left claw hand assembly on the fifth mounting plate 100 and the right claw hand assembly on the sixth mounting plate 102 to move toward each other through the second feeding cylinder to adapt to bags of different sizes.

[0078] like Figure 8 and Figure 9As shown, the packaging area is equipped with a labeling device, which includes a labeling plate 111, a labeling pulley 112, and a label clamping seat 121. The labeling plate 111 is mounted on the mounting bracket 1, the labeling pulley 112 and the label clamping seat 121 are mounted on the front side of the labeling plate 111, and the seventh cylinder 130 and the cutter drive cylinder 132 are mounted on the rear side of the labeling plate 111.

[0079] like Figure 10 As shown, a label pulley 112 is rotatably mounted on one end of the front side of the labeling stand 111 via a second rotating shaft 113, and the label tape is mounted on the label pulley 112. A V-shaped baffle 114 is provided at the outlet of the label pulley 112 to compress the label tape. The baffle 114 is rotatably mounted on the front side of the labeling stand 111 at its angle via a third rotating shaft 115. One end of the baffle 114 abuts the label pulley 112, and the other end of the baffle 114 has a downwardly extending fifth connecting portion 114a. An adjustment slot 111a is provided on the labeling stand 111, located below the label pulley 112. A tension spring 116 is installed on the front side of the labeling stand 111. One end of the tension spring 116 is mounted in the adjustment slot 111a via 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 blocking piece 114 so that the blocking piece 114 can always press the label tape tightly to prevent the label tape wheel 112 from rolling out excess label tape.

[0080] The front side of the labeling stand 111 is also equipped with a first rotating wheel 117, a second rotating wheel 118, and a fixed base 119. The label strip passes sequentially along the lower arc of the first rotating wheel 117, the upper arc of the second rotating wheel 118, and the lower surface of the base of the fixed base 119. A second air blowing pipe 120 is located below the fixed base 119. This blows air continuously, keeping the label close to the lower surface of the base of the fixed base 119. A recessed label clamping groove 119a is located on one side of the base of the fixed base 119 to facilitate the label strip's removal.

[0081] The label clamping seat 121 is rotatably mounted on the other end of the front side of the labeling vertical plate 111 via a fourth rotating shaft 122. The label clamping block mounting seat 123 is mounted on the front side of the label clamping seat 121. A fifth cylinder 124 is mounted on one side of the label clamping mounting plate. The driving rod of the fifth cylinder 124 is connected to the label clamping block 125. The bottom of the label clamping block mounting seat 123 has a label clamping bottom block 123a that cooperates with the label clamping block 125. The fifth cylinder 124 drives the label clamping block 125 downward to cooperate with the label clamping block to clamp the label.

[0082] The pressure block mounting seat 126 is installed on the front side of the label clamping seat 121.

The sixth cylinder 127 drives the pressure block 128 to move downward.

[0083] A transmission block 129 is mounted on the rear side of the labeling stand 111, rotatably connected to the fourth rotating shaft 122. The other end of the transmission block 129 is connected to the drive rod of the seventh cylinder 130 via a joint. When the drive rod of the seventh cylinder 130 retracts, the transmission block 129 rotates, which in turn rotates the fourth rotating shaft 122. The fourth rotating shaft 122 drives the label clamping seat 121 toward the fixed seat 119, causing the label clamping block 125 to rotate above the label clamping slot 119a. The fifth cylinder 124 then drives the label clamping block 125 to clamp the label. The drive rod of the seventh cylinder 130 extends, causing the label clamping seat 121 to rotate about the fourth rotating shaft 122, and the label clamping block 125 to clamp the label, pulling out a section of the label strip.

[0084] A cutter 131 for cutting the label strip is located on the front of the labeling stand 111, positioned to one side of the mounting base 119. A cutter drive cylinder 132 is mounted on the rear of the labeling stand 111, driving the cutter 131 up and down. The cylinder body of the cutter drive cylinder 132 is mounted on the rear of the labeling stand 111, and its drive rod is connected to the cutter 131 on the front of the labeling stand 111 via a cutter connecting plate 133. After the label clamp 125 pulls out the label strip, the cutter drive cylinder 132 drives the cutter 131 upward, severing the label strip. The severed label strip is now positioned below the pressure block 128, which is then driven downward by the sixth cylinder 127, attaching the label to the bag material, completing the labeling process.

[0085] The best embodiment of the present invention has been described, and various changes or modifications made by ordinary technicians in this field will not depart from the scope of the present invention.
