If the specific posture changes, the directional indication will also change accordingly.

[0034] In addition, the descriptions of “first”, “second”, etc. in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.

[0035] The present invention provides a bag filling and sealing device, which has a table 100, on which a conveying mechanism 200, a bag opening mechanism 210, a transfer mechanism 220, and a bag sealing mechanism 230 are further arranged, wherein the conveying mechanism 200 includes a first conveying mechanism 200a and a second conveying mechanism 200b which are arranged in a predetermined direction and have the same structure and are arranged side by side with each other, and the first conveying mechanism 200a and the second conveying mechanism are used to convey packaging bags and workpieces respectively; the bag opening mechanism 210 is arranged on the first conveying mechanism 200a, and is used to open the packaging bags conveyed by the first conveying mechanism 200a, and includes a negative pressure structure arranged on the first conveying mechanism 200a and a negative pressure structure suspended between the negative pressure structure. The bag opening cylinder 211 on the bag opening cylinder is fixedly connected to a suction nozzle 212, and the suction nozzle 212 moves back and forth toward the direction of the negative pressure structure under the drive of the bag opening cylinder 211; the transfer mechanism 220 and the bag opening mechanism are arranged corresponding to each other, and the transfer mechanism is used to push the workpiece toward the bag opening mechanism 210 and push it into the packaging bag. The transfer mechanism 220 includes a transfer cylinder 221 and a pushing block 222. The transfer cylinder 221 is fixedly arranged and is transmission-connected with the pushing block 222 to drive the pushing block to move back and forth toward the direction of the bag opening mechanism; the bag mechanism is arranged on the downstream side of the bag opening mechanism 210 along the conveying direction of the first conveying mechanism 200a, and is used to seal the opening of the packaging bag loaded with the workpiece.

[0036] During the process of bagging and sealing the items, the packaging bag is transported by the first conveying mechanism 200a. It can be understood that the bag opening of the packaging bag is provided with a bag opening mechanism 210 on one side. When transported to the bag opening mechanism 210, the negative pressure structure of the bag opening mechanism 210 adsorbs the lower surface of the packaging bag, and the bag opening cylinder 211 moves the suction nozzle 212 toward the negative pressure structure, thereby adsorbing the upper surface of the packaging bag. At this time, the bag opening cylinder 211 drives the suction nozzle 212 to move upward, thereby separating the two sides of the packaging bag to complete the bag opening. The transfer mechanism 220 pushes the items located on the second conveying mechanism 200b toward the bag opening mechanism 210, thereby pushing them into the packaging bag along the bag opening; then, the packaging bag containing the items is conveyed again along the conveying direction by the first conveying mechanism 200a, and is transported to the bag sealing mechanism 230 for sealing the packaging bag containing the items. The technical solution provided by this embodiment can conveniently open two flat packaging bags, so that the items can be quickly and directly loaded into the packaging bags under the push of the transfer mechanism 220, and the bag sealing process is completed immediately. The processing continuity is strong, the bag filling and sealing efficiency is high, and the production cost is reduced.

[0037] In this embodiment, if Figure 2 、 5 As shown, the conveying mechanism 200 includes a frame 201, a drive device 202, and a conveyor belt 203. The frame 201 is fixedly mounted on the table 100 along a predetermined direction, and has rotating shafts at both ends of the frame 201. The drive device 202 is fixedly mounted on the frame 201 and is drivingly connected to any one of the rotating shafts to drive the rotating shaft to rotate. The conveyor belt is sleeved on the two rotating shafts and is driven to rotate by the rotating shafts. Multiple dry baffles 204 are evenly spaced on the conveyor belt 203, and two adjacent baffles 204 define a placement space 205 for placing packaging bags or workpieces. The conveyor belt 203 is rotated by the rotating shaft, thereby completing the conveying of packaging bags or workpieces.

[0038] During the conveying process, the first conveying mechanism 200a is used to convey the packaging bags, that is, the packaging bags are placed in the placement space 205 of the first conveying mechanism 200a, and two adjacent packaging bags are separated by a baffle 204. Similarly, the workpiece is conveyed by the second conveying mechanism 200b and is also arranged in the placement space 205 above the second conveying mechanism 200b. Two adjacent workpieces are separated by a baffle 204. When the workpiece is pushed into the packaging bag, the first conveying mechanism 200a and the second conveying mechanism 200b are pre-set through the control system. The control system mentioned in this embodiment can be a PLC system. The control system can make the transfer cylinder 221 push the workpiece toward the packaging bag through the pushing block 222. The placement spaces 205 of the first conveying mechanism 200a and the second conveying mechanism 200b are aligned with each other to facilitate the smooth pushing of the workpiece into the packaging bag, and due to the separation by the baffle 204, when the workpiece is bagged, it will not interfere with the adjacent workpiece.

[0039] In this embodiment, the bag opening mechanism 210 is used to open the packaging bag so that the bag opening is opened, which can facilitate the bagging of the workpiece under the push of the transfer mechanism 220. The negative pressure structure in the bag opening mechanism 210 includes a suction cup 213 fixedly mounted on the frame 201, and the suction cup 213 is adjacent to the edge of the conveyor belt 203.

[0040] The bag opening mechanism 210 further includes a mounting frame 214, the mounting frame 214 is fixedly mounted on the frame 201, and the bag opening cylinder 211 is fixedly mounted on the mounting frame 214. The suction cup 213 and the suction nozzle 212 are arranged alternately.

[0041] During the process of the packaging bag being transported by the first conveying mechanism 200a, one end of the opening of the packaging bag is facing the side where the negative pressure structure is provided, and at the same time, it is also facing the second conveying mechanism 200b and the transfer mechanism 220. During the bag opening process, when the packaging bag is transported to the position of the negative pressure structure, the suction cup 213 adsorbs the lower surface of the packaging bag. At the same time, the bag opening cylinder 211 has a suction nozzle 212 driven downward, so as to facilitate the adsorption of the upper surface of the packaging bag. When the bag opening cylinder 211 moves the suction nozzle 212 upward, the upper and lower surfaces of the packaging bag can be separated from each other, thereby completing the bag opening work. And by staggering the suction cup 213 and the suction nozzle 212, when the upper surface and the lower surface of the packaging bag are adsorbed respectively, the adsorbed points on the upper surface and the lower surface are staggered. When the bag opening cylinder 211 drives the suction nozzle 212 to lift, the packaging bag in a horizontal state can bend in a wave-like manner, thereby facilitating the opening of the packaging bag. It is worth noting that when the suction cup 213 and the suction nozzle 212 are aligned with each other, when the bag opening cylinder 211 lifts the suction nozzle 212, since the upward pulling force and the downward pulling force are in the same straight line, the packaging bag is easy to fall off the suction nozzle 212 or the suction cup 213, affecting the efficiency of bag opening.

[0042] In this embodiment, after the workpiece is placed in the packaging bag, it is again conveyed to the bag sealing mechanism 230 via the first conveying mechanism 200a, and in particular, the bag opening of the packaging bag is heat-sealed. Figure 2 、 4 As shown, the bag-sealing mechanism 230 includes a bracket 231 and a sealing cylinder. The bracket 231 is fixedly mounted on the frame 201 and extends upward. The bag-sealing cylinder 232 is fixedly mounted on the bracket 231 and has a piston rod that extends vertically. A heating block 233 is fixedly connected to the piston rod. The packaging bag containing the workpiece is conveyed to the lower side of the sealing cylinder. The bag-sealing cylinder 232 drives the heating block 233 downward, thereby heat-sealing the opening of the packaging bag. In this embodiment, the heating block 233 is internally provided with a heating resistor and is connected to an external power source, so that the heating block 233 has enough heat to heat-seal the opening of the packaging bag.

[0043] In this embodiment, to enable the transfer mechanism 220 to push the workpiece into the packaging bag, the transfer mechanism 220 further includes a docking plate 223. The two ends of the docking plate 223 are respectively fixedly connected to the frames 201 of the first conveying mechanism 200a and the second conveying mechanism 200b. Side plates 224 are formed on both sides of the docking plate 223, defining passages 225 for conveying the workpiece. When the workpiece is pushed into the packaging bag, it can be pushed through the passages 225 within the docking plate 223.

[0044] In this embodiment, in order to facilitate pushing the workpiece along the docking plate 223, the side plate 224 is bent in directions away from each other toward the transfer mechanism 220 to form a trumpet-shaped inlet 226.

[0045] To facilitate the transport of packaging bags, a loading robot 300 is also installed on the table 100. A loading suction head 310 is fixed to the end of the loading robot 300 to pick up the packaging bags and transfer them to the first conveyor mechanism 200a. The robot 300 thus grabs the packaging bags and transfers them to the first conveyor mechanism 200a, improving automation capabilities.

[0046] The present embodiment provides a bagging and sealing device, which transports the packaging bag and the workpiece separately, and the bag opening mechanism 210 opens the packaging bag. The suction nozzle 212 and the suction cup 213 of the bag opening mechanism 210 are staggered with each other, which can ensure smooth bag opening and prevent the packaging bag from falling off the suction cup 213 or the suction nozzle 212. The transfer mechanism 220 pushes the workpiece along the docking plate 223 toward the inside of the packaging bag to complete the bagging work, and then the bag sealing mechanism 230 heat-seals the bag opening of the packaging bag. The bagging and sealing device provided by the present embodiment can smoothly open the packaging bag, and the opening action is simple and reliable. During the bagging process of the workpiece, the workpiece can be directly pushed into the bag opening of the packaging bag, and the bagging can be done quickly, thereby improving the efficiency of bag opening and bagging, reducing the participation of operators, and reducing production costs.
