[0035] Working principle and beneficial effects of the present invention: A feeding and bagging mechanism provided by the present invention. When the packaging bag is conveyed to the bag opening assembly by the packaging bag conveying mechanism, the bottom negative pressure adsorption box and the suction cup are connected to the negative pressure source of the negative pressure, and both sides of the bag mouth of the packaging bag are sucked. Then, the bag opening cylinder drives the suction cup fixing plate and the suction cup to rise, so as to pull up the upper bag body at the bag mouth of the packaging bag. At this time, the lower bag body at the bag mouth of the packaging bag is sucked by the bottom negative pressure adsorption box, so as to realize bag opening. Then, the bag inserting cylinder pushes the bag supporting cylinder plate forward, so that the bag supporting plate in the reset state enters the bag mouth of the packaging bag. Then, the bag opening cylinder drives the bag supporting plates installed on the bag supporting arms to move away from each other, so that the bag supporting plates support the inner surface of the bag mouth of the packaging bag, so as to form a stably opened bag mouth. At the same time, after the feeding conveyor belt of the feeding assembly conveys the material to the position directly in front of the pushing plate and pauses, at this time, the bag inserting assembly is in the reset state, the upper clamping plate and the lower clamping plate are in the open state of moving away from each other, and the leveling plate rises and enters the long groove on the lower clamping plate, filling the long groove on the lower clamping plate, so that the upper end surface of the lower clamping plate becomes a complete plane. The pushing plate advances under the drive of the pushing cylinder, and pushes the material onto the lower clamping plate. Then, the upper clamping plate is driven by the clamping cylinder to descend and cooperate with the lower clamping plate to clamp the material between the upper clamping plate and the lower clamping plate, and the leveling plate descends and moves away from the lower clamping plate. Then, the servo motor drives the second synchronous belt to run forward to drive the bag inserting seat to advance, and further drives the upper clamping plate and the lower clamping plate clamping the material to enter the packaging bag. Then, the bag pressing cylinder drives the bag pressing column to descend to press the packaging bag containing the material on the bearing plate. Then, the servo motor drives the second synchronous belt to run backward to drive the bag inserting seat to retreat to reset the bag inserting assembly. At this time, since the bag pressing column is located at the long groove position, therefore, only the packaging bag and the material are pressed. When the upper clamping plate and the lower clamping plate withdraw from the packaging bag, the material will not be taken out of the packaging bag, and the position of the material after being loaded into the packaging bag is kept stable. Then, the bag supporting plate is folded and reset, and under the drive of the bag inserting cylinder, it withdraws from the bag mouth position of the packaging bag, so as to reset the bag opening assembly. Finally, the bag pressing cylinder drives the bag pressing column to rise and reset, loosening the packaging bag containing the material, and the packaging bag is conveyed away by the packaging bag conveying mechanism. In this way, the bagging of the material is carried out in a cycle, which has the advantages of high production efficiency, good bagging reliability and low labor cost. Description of the Drawings

[0075] A feeding and bagging mechanism provided by the present invention. After the packaging bag is conveyed to the bag opening assembly 3 by a packaging bag conveying mechanism (not shown), the bottom negative pressure adsorption box 301 and the suction cup 302 are connected to the negative pressure of the negative pressure source to suck both sides of the bag mouth of the packaging bag. Here, the negative pressure source can be a negative pressure fan or a vacuum pump. Then, the bag opening cylinder 306 drives the suction cup fixing plate 303 and the suction cup 302 to rise, so as to pull up the upper bag body at the bag mouth of the packaging bag. At this time, the lower bag body at the bag mouth of the packaging bag is sucked by the bottom negative pressure adsorption box 301 to realize bag opening. Then, the bag inserting cylinder 313 pushes the bag supporting cylinder plate 312 forward so that the bag supporting plate 309 in the reset state enters the bag mouth of the packaging bag. Then, the bag opening cylinder 306 drives the bag supporting plates 309 installed on the bag supporting arms 310 to move away from each other, so that the bag supporting plates 309 support the inner surface of the bag mouth of the packaging bag, thus forming a stably opened bag mouth. At the same time, the feeding conveyor belt 501 of the feeding assembly 5 conveys materials such as masks, socks or insoles to the position directly in front of the pushing plate 505 and then pauses. At this time, the bag inserting assembly 2 is in the reset state, the upper clamping plate 201 and the lower clamping plate 202 are in the open state of moving away from each other, and the leveling plate 203 rises into the long groove 215 on the lower clamping plate 202 to fill the long groove 215 on the lower clamping plate 202, so that the upper end surface of the lower clamping plate 202 becomes a complete plane. The pushing plate 505 advances under the drive of the pushing cylinder 504 to push the materials onto the lower clamping plate 202. Then, the upper clamping plate 201 is driven by the clamping cylinder 213 to descend and cooperate with the lower clamping plate 202 to clamp the materials between the upper clamping plate 201 and the lower clamping plate 201, and the leveling plate 203 descends away from the lower clamping plate. Then, the servo motor 206 drives the second synchronous belt 208 to run forward to drive the bag inserting seat 204 to advance, and further drives the upper clamping plate 201 and the lower clamping plate 202 clamping the materials into the packaging bag, which can effectively prevent the materials from shifting and falling, ensuring the stability and reliability of the bag inserting process. Then, the bag pressing cylinder 403 drives the bag pressing column 406 to descend to press the packaging bag containing the materials onto the bearing plate 407. Then, the servo motor 206 drives the second synchronous belt 208 to run backward to drive the bag inserting seat 204 to retreat to reset the bag inserting assembly 2. At this time, since the bag pressing column 406 is located at the position of the long groove 215, therefore, only the packaging bag and the materials are pressed. When the upper clamping plate 201 and the lower clamping plate 202 withdraw from the packaging bag, the materials will not be taken out of the packaging bag, maintaining the stable position of the materials after being loaded into the packaging bag. Then, the bag supporting plate 309 retracts and resets, and under the drive of the bag inserting cylinder 313, it withdraws from the bag mouth position of the packaging bag to reset the bag opening assembly 3. Finally, the bag pressing cylinder 403 drives the bag pressing column 406 to rise and reset to release the packaging bag loaded with materials, and the packaging bag loaded with materials is conveyed away by the packaging bag conveying mechanism. In this way, the bagging of materials is carried out in a cycle. Here, the materials include but are not limited to socks or insoles, which have the advantages of high production efficiency, good bagging reliability and low labor cost.
