Description

Technical Field

[0001] This utility model belongs to the field of vest bag production technology, and in particular relates to an automatic folding and bagging machine for vest bags. Background Technology

[0002] In the production process of vest bags, after the bag-making machine completes the heat sealing and punching of the bag body, the finished bags need to be folded and sorted to facilitate subsequent bundling, bagging, transportation, and sales. Traditional sorting methods have the following drawbacks: Manual folding is inefficient: In the early days, folding was mostly done manually, which was labor-intensive, had extremely low production efficiency, and the folding quality was inconsistent, making it difficult to meet the high-speed production pace of automated production lines.

[0003] Simple machinery has limited functionality: Some existing simple folding devices have limited functionality and can usually only complete one folding action. For high-quality requirements that need to form a neat and compact stack, a second fold is often required. The second fold depends on another piece of equipment or another workstation, resulting in an excessively long production line, a large floor space, high equipment costs, and easy errors in the connection between different workstations.

[0004] The contradiction between folding quality and efficiency: Some equipment attempts to complete complex actions at a single station, but often suffers from inaccurate folding, bag misalignment, wrinkling, or even damage. This is especially true for lightweight and soft plastic film bags, which lack rigidity and are difficult to control precisely during high-speed movement. How to efficiently and reliably complete multiple precise folds in a continuous process without damaging the bag has always been a technical challenge in this field.

[0005] Collaboration issues with upstream and downstream equipment: Folded bags need to be stacked and conveyed to the bagging machine. Traditional equipment suffers from poor coordination between modules, resulting in uneven stacking and affecting the success rate of subsequent automated bagging.

[0006] Therefore, there is an urgent need for a fully automated folding and bagging device that is highly integrated, has coordinated movements, can continuously complete multiple precise folds, and ensures stacking quality, in order to solve the above-mentioned technical problems. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic folding and bagging machine for vest bags. Through the coordinated operation of the first and second folding mechanisms in front of the clamping line, two precise folds can be automatically and continuously completed in one station without manual intervention, which greatly improves production efficiency and perfectly matches the production rhythm of high-speed bag making machines. Utilizing the flexible characteristics of the film itself, folding is performed by pressing and feeding it between two rollers, rather than rigidly pulling. The action is gentle, avoiding damage to the bag body and improving product quality. Furthermore, the two folding functions are highly integrated into one module, and through seamless connection with the clamping line, the production line length is significantly shortened, and the equipment footprint is reduced.

[0042] The working principle of this utility model is as follows: Folding Device: In the initial state, the lifting plate 302 of the first folding mechanism 3 is in the upper position, and the horizontal plate 402 of the second folding mechanism 4 is away from the pressure roller 101. The vest bag, after being bagged by the bag-making machine, is conveyed to the top between the upper belt and the pressure roller 101. The linkage reciprocating lifting drive controls the support plate 27 to rotate a certain angle, thereby pulling down the vertical rod 304 through the first connecting rod 306, controlling the lifting plate 302 to descend, thereby pressing the center line of the vest bag into the clamping interval 102, activating the drive mechanism 205 of the clamping line, and enabling the pressure roller 101 and the front roller 201 of the upper belt to fold the vest bag in half. The bag is conveyed downwards, and the linkage-type reciprocating translation drive controls the ear plate 27 to rotate at a certain angle, thereby pushing the horizontal thin plate 402 to move towards the clamping channel through the second linkage 405. This feeds the folded vest bag into the clamping channel from the center line. The cooperation between the upper and lower belt lines folds the vest bag again and conveys it backwards. Finally, it is guided to the bag-forming platform 7 through the transition table 103. The lifting cylinder 502 can start the main bag-forming plate 503 and the auxiliary bag-forming plate 505 to pat downwards to form the bag. The bag-forming cylinder (705) drives the bag-forming rod 707 to extend and retract up and down to form the bag from the bottom. The two side baffles 507 limit the movement on both sides.

[0043] Transfer: The bag-grabbing mechanism 12 controls the presser 1203 to press down, and adjusts the cylinder 709 to flip the sub-table 708 downward at a certain angle, so that the upper part of the stacked vest bags is pressed by the presser 1203 and the lower part is supported by the lower pad rod 1207, thereby grabbing the stacked bags and moving them to the top of the two guide rollers 8 on the second frame 6 by the bag-moving slide 11.

[0044] Bagging Device: The bagging film is fed from the bagging feeder 13 through the lifting roller mechanism 22, the tear line mechanism 23, and the guide roller 24, then passes through the bagging mold 17. In the bagging mold 17, the bagging film is separated with its top open. The lifting device 15 controls the opening support mechanism 16 to move down to the bagging mold 17, opening the top of the bagging film into a certain shape and forming a certain clamping force. During the continued film feeding, the lifting device 15 continues to drive the opening support mechanism 16 to move up. After reaching the position, the film feeding stops, and the bottom sealing mechanism 18 can perform bottom heat sealing. The bag gripping mechanism 12 releases the clamping of the bag, and the lifting slide 9 controls the guide plate 10 to move down, pressing the vest bag through the two guide rollers 8 and... The vest bag falls into the bag, and the guide plate 10 is not only used for feeding the vest bag, but also works with the guide roller 8 to guide it, resist the friction between the vest bag and the bag and create an "opening angle" that makes it easy to put on. After the number of bags in the bag reaches the standard, the bag with the vest bag is clamped at four points by the robotic arm bag clamping mechanism 20. The bag bottom cutting mechanism 19 cuts the bag to form a bag with the vest bag at the top open. The top of the bag with the vest bag is transferred to the bag opening heat sealing mechanism 21 by the robotic arm bag clamping mechanism 20 for bag opening heat sealing, and the packaging is completed. The packaging is then sent to the discharge conveyor belt for output by the robotic arm bag clamping mechanism 20. After each mechanism completes its own action, it resets and waits for the next process.
