Technical Field
[0001] This utility model relates to the field of packaging equipment technology, specifically a packaging machine with a bottom bag compartment. Background Technology
[0002] Existing packaging machines typically have complex bag-picking devices with low efficiency. During the picking process, bags are prone to damage or unstable picking, affecting packaging quality. Furthermore, the bag storage capacity is limited, requiring frequent bag changes, increasing labor costs and production time. These machines also suffer from high manufacturing costs, complex assembly processes, low equipment integration, inconvenient transportation requiring separate transport and repositioning of individual parts, and long installation times. Utility Model Content
[0003] To address the problems mentioned in the background art, this utility model provides a packaging machine with a bottom bag compartment, including a bag compartment mechanism, a bag picking mechanism, and a conveying mechanism. The bag compartment mechanism has a fixed frame at its upper end, and the bag picking mechanism is located within the fixed frame. A conveying mechanism is located on one side of the bag picking mechanism. The bag compartment mechanism includes a bag compartment support, linear guide rails, and bag compartments. Linear guide rails are located on both sides of the upper end of the bag compartment support, and two bag compartments are mounted on the linear guide rails. Each bag compartment includes a slider, a fixed plate, a support frame, bag hanging rods, and a bag compartment tray. A slider is located at the lower end of the fixed plate, and a support frame is located at the upper end of the fixed plate. Two parallel bag hanging rods are located on one side of the fixed plate for hanging bags. The rod passes through the support frame and is fixed to the fixed plate. The part of the bag-hanging rod above the support frame is fitted with a bag tray. The bag-picking mechanism includes a bag-picking cylinder, a bag-picking suction cup, and a bag-feeding cylinder. A bag-feeding cylinder is provided on one side of the fixed frame. The extended end of the bag-feeding cylinder is fixedly connected to the bag-picking cylinder base. A bag-picking cylinder is provided on the bag-picking cylinder base. A bag-picking suction cup is fixedly installed on the extended end of the bag-picking cylinder. The conveying mechanism includes a clamping mechanism, a conveyor belt, a drive motor, a drive wheel, and a driven wheel. A driven wheel is provided on one side of the clamping mechanism, and a drive motor is provided on the other side of the fixed frame.

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] like Figures 1 to 3A packaging machine with a bottom bag compartment includes a bag compartment mechanism, a bag picking mechanism, and a conveying mechanism. The bag compartment mechanism has a fixed frame 11 at its upper end, and the bag picking mechanism is located inside the fixed frame 11. A conveying mechanism is located on one side of the bag picking mechanism. The bag compartment mechanism includes a bag compartment support 1, linear guide rails 2, and bag compartments. Linear guide rails 2 are located on both sides of the upper end of the bag compartment support, and two bag compartments are located on the linear guide rails 2. Each bag compartment includes a slider 3, a fixed plate 4, a support frame 5, hanging rods 6, and a bag compartment tray 7. The slider 3 is located at the lower end of the fixed plate 4, and the support frame 5 is located at the upper end of the fixed plate 4. Two parallel hanging rods 6 are located on one side of the fixed plate 4, passing through the support frame 5 and fixed to the fixed plate 4. The hanging rods 6 are located on the support frame 5. The upper part is fitted with a bag storage tray 7. The bag retrieval mechanism includes a bag retrieval cylinder 12, a bag retrieval suction cup 13, and a bag delivery cylinder 14. A bag delivery cylinder 14 is located on one side of the fixed frame 11. The extended end of the bag delivery cylinder 14 is fixedly connected to a bag retrieval cylinder base. The bag retrieval cylinder 12 is mounted on the bag retrieval cylinder base, and a bag retrieval suction cup 13 is fixedly installed on the extended end of the bag retrieval cylinder 12. The conveying mechanism includes a clamping mechanism, a conveyor belt 15, a drive motor 16, a drive wheel 17, and a driven wheel 18. A driven wheel 18 is located on one side of the clamping mechanism, and a drive motor 16 is located on the other side of the fixed frame 11. The output shaft of the drive motor 16 is connected to the drive wheel 17, and the drive wheel 17 and the driven wheel 18 are connected by the conveyor belt 15. The main function of the bag storage is to store bags. There are two bag storage compartments. When the bags in one compartment are used up, they automatically move to the sides for manual replenishment. The other bag storage compartment moves to the working position below the bag retrieval mechanism for bag supply.
[0016] The upper surface of the support frame 5 is equipped with a photoelectric sensor 9 for remaining storage bags, which is used to detect whether the bag compartment is empty.
[0017] The support frame 5 has symmetrical bag bin guard plates 8 on both sides. The upper end of the bag bin guard plate 8 is equipped with a bag height photoelectric sensor 10 to detect the consumption of the bag bin so as to control the material replacement time.
[0018] The clamping mechanism includes a clamping roller 19, a clamping cylinder 20, a clamping belt 21, and a conveyor wheel assembly 22. The extended end of the clamping cylinder 20 is connected to the clamping roller 19. Several conveyor wheel assemblies 22 are provided on one side of the clamping roller 19, and the conveyor wheel assemblies 22 are connected to each other by the clamping belt 21. The inlet of the clamping belt 21 is located on one side of the bag-picking suction cup 13. There is a conveyor wheel assembly 22 on the outside of the driven wheel 18. There is a gap between the conveyor belt 15 on the outside of the driven wheel 18 and the clamping belt 21 of the conveyor wheel assembly 22, and the gap is only wide enough for conveyed materials to pass through. When the bag-picking suction cup 13 picks up the bag and sends it to the clamping belt 21 for clamping, the bag will fall downward under the action of gravity. Therefore, a clamping roller 19 is installed at the inlet of the clamping belt 21. When there is a bag, the clamping cylinder 20 lifts the clamping roller 19 to clamp the bag, keeping the bag flat when it is at the inlet of the clamping belt 21 so that the clamping belt 21 can clamp and roll it onto the working surface 25.
[0019] A baffle 23 is provided at the upper end of the fixing frame 11.
[0020] In operation, both bag bins are filled with material. One bag bin is moved to the working position to supply bags, and the bag-retrieving mechanism retrieves the bags. The bag-retrieving cylinder 12 controls the bag-retrieving suction cup 13 to move up and down to retrieve the bags. As the bag-feeding cylinder 14 sends the bags to the inlet of the clamping belt 21, the clamping cylinder 20 lifts up and clamps the bags. The bag-feeding cylinder 14 continues to send the bags to the clamping belt 21. Then, the bags are rolled onto the working surface 25 under the clamping of the clamping belt 21 and the conveyor belt 15, completing the bag retrieval. During the continuous bag retrieval process, when the photoelectric sensor 9 of the remaining bag storage in the bag bin does not detect any bags, it means that the bags in that bag bin are all gone. Then, the other bag bin is switched, and the other bag bin moves to the working position, while the bag bin moves to the bagging position to be manually replenished with bags. The process continues without stopping, and this cycle repeats.
