The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] Reference Figure 3 , 5 As shown in Figure 6, a pipe bundling mechanism includes a tightening belt assembly 210, a feeding and retracting belt assembly 220, an annular belt path 230, and a hot cutter assembly; the tightening belt assembly 210 is used to tighten the bundling belt; the feeding and retracting belt assembly 220 is used to transport the bundling belt passing through the tightening belt assembly 210; the annular belt path 230 is used to wrap the bundling belt around the pipe; and the hot cutter assembly is used to fix and cut the bundling belt.

[0028] After passing through the tightening belt assembly 210, the strapping belt is sent into the annular belt path 230 by the retracting belt assembly 220 and wrapped around the pipe. After the end of the strapping belt enters the hot cutter assembly along the annular belt path 230 and is fixed, the tightening belt assembly 210 will tighten the strapping belt so that the strapping belt is tightly wrapped around the pipe, and the hot cutter assembly will then heat-seal and cut the strapping belt.

[0029] The tightening belt assembly 210 includes a tightening belt cylinder 211, a clamping block 212, and a base plate 213. The piston rod end of the tightening belt cylinder 211 is rotatably equipped with a connecting rod 214, and the connecting rod 214 is rotatably connected to the clamping block 212. The clamping block 212 slides through a slide rail assembly 215 and is installed on the base plate 213. The slide rail assembly 215 is longitudinally arranged.

[0030] When the strapping belt is tightened, the tightening cylinder 211 pulls the clamping block 212 through the connecting rod 214, so that the clamping block 212 moves upward along the slide rail assembly 215, so that the clamping block 212 pulls the strapping belt upward, so that the strapping belt is tightened around the pipe.

[0031] The feed-return belt assembly 220 includes a feed-return belt pulley 221, an eccentric pressure wheel 222, a fan-shaped gear 223, a rack 224, and a belt path 225. The feed-return belt pulley 221 is mounted on a servo motor; the eccentric pressure wheel 222 is pressed on the feed-return belt pulley 221; the eccentric pressure wheel 222 is connected to the fan-shaped gear 223, the fan-shaped gear 223 is meshed with the rack 224, the rack 224 is vertically arranged, and the rack 224 is connected to the feed-return belt cylinder 226.

[0032] During operation, the belt feed and rewind cylinder 226 pushes the rack 224. When the rack 224 moves, the fan-shaped gear 223 meshing with the rack 224 rotates, thereby causing the eccentric pressure wheel 222 to rotate, causing the eccentric pressure wheel 222 to contact with the belt feed and rewind pulley 221, and the servo motor drives the belt feed and rewind pulley 221 to rotate clockwise to perform the belt feeding action; when the contact between the eccentric pressure wheel 222 and the belt feed and rewind pulley 221 is released, the servo motor drives the belt feed and rewind pulley 221 to rotate counterclockwise to perform the belt rewinding action.

[0033] Reference Figure 1 As shown, an automatic strapping machine includes a material sorting mechanism 100, a bagging mechanism 300, a lifting bracket 400, and a tube turning mechanism 500. A strapping mechanism 200 is installed between the material sorting mechanism 100 and the bagging mechanism 300, and the strapping mechanism 200 adopts the above-mentioned tube strapping mechanism; the material is fed to the strapping mechanism 200 by the material sorting mechanism 100, and the tubes are strapped by the strapping mechanism 200. After strapping, the tubes are fed into the bagging mechanism 300 for bagging. After bagging, the tubes are lifted by the lifting bracket, and after lifting, the tubes are turned onto the logistics cage by the tube turning mechanism 500.

[0034] Reference Figure 3 ,4 As shown, a tube pressing assembly 250 and a tube blocking assembly 260 are sequentially arranged in front of the bundling mechanism 200 .

[0036] The pipe blocking assembly 220 includes a pipe blocking cylinder 261 and a baffle 262 . The baffle 262 is connected to the pipe blocking cylinder 261 . The pipe blocking cylinder 261 pulls the baffle 262 upward or pushes the baffle 262 downward.

[0037] The strapping assembly 230 is moved by the packing moving cylinder to wrap the strapping tape around the pipe for one cycle and then clamp it, and retract the excess strapping tape so that the strapping tape can tighten the pipe.

[0038] Reference Figure 2 As shown, the material sorting mechanism 100 includes a pipe delivery channel 110, a pipe arrangement assembly 120, and a pipe pushing assembly 130. The pipe arrangement assembly 120 is arranged below the pipe delivery channel 110, and the pipe arrangement assembly 120 faces the pipe pushing assembly 130. A pipe turning baffle 140 is arranged at the delivery end of the pipe delivery channel 110. When the pipe is delivered to the delivery end of the pipe delivery channel 110, the pipe collides with the pipe turning baffle 140, causing the pipe to turn over and fall onto the pipe arrangement assembly 120, and the pipes are arranged according to the number of pipes bundled each time. After the arrangement, the pipes enter the pipe pushing assembly 130, and the pipes are pushed to the bundling mechanism 200 for bundling by the pipe pushing assembly 130.

[0039] The pipe arrangement assembly 120 includes an upper pipe rack 121 and a lower pipe rack 122. The pipe falls from the pipe delivery channel 110 to the upper pipe rack 121 below, and then rolls obliquely downward along the upper pipe rack 121 to the lowest point. The guide baffle (262) 123 changes the direction of the pipe and rolls it to the lower pipe rack 122. The pipe rolls obliquely along the lower pipe rack 122 to the pipe pushing assembly 130. A ramp knife 124 is installed on the lower pipe rack 122. When the number of pipes entering the pipe pushing assembly 130 meets the preset number of pipes, the ramp knife 124 rises to prevent the pipes from continuing to roll into the pipe pushing assembly 130, so that the pipes are arranged in order for bundling.

[0040] The tube pushing assembly 130 includes a pushing groove 131 and a pushing block 132. The pushing groove 131 is located below the tube assembly 120. The pushing block 132 is located in the pushing groove 131 and moves in the direction of the bundling mechanism (200) 200. Pushing racks 133 are installed on both sides of the pushing block 132. A slider seat 134 is installed at the bottom of the pushing rack 133. The slider seat 134 is slidably mounted on a slide rail 135. The pushing rack 133 moves on the slide rail 135, so that the pushing block 132 pushes the tube in the pushing groove 131, so that the tube enters the bundling mechanism (200) 200.

[0042] When bagging, the bag clamping claw 320 grasps the bag opening of the packaging bag and moves in the direction of the guide sleeve 330 to put the packaging bag on the tube. The heat sealing component heat-seals the packaging bag. After the sealing is completed, the bag cutting knife moves from bottom to top to cut the bag.

[0043] A tube turning mechanism 500 is provided at the highest point of the lifting bracket 400, and the tube turning mechanism 500 includes a tube turning rod 510 and a double motor 520. A tube turning rod 510 is respectively installed at both ends of the double motor 520, and a holding plate 530 is installed on the tube turning rod 510. The double motor 520 rotates the tube turning rod 510 to turn the tube turning rod 510. The packaged tubes are lifted to the highest point by the lifting bracket 400 and sent to the holding plate 530. The double motor 520 rotates the tube turning rod 510 to turn the tube turning rod 510 onto the logistics cage.

[0044] In this embodiment, the tool assembly can be used in the following manner: the tool assembly includes a tool groove, a first pressure block, a second pressure block, a third pressure block, and a blade.
