Description

Technical Field

[0001] The present invention belongs to the technical field of potassium superoxide preparation, and specifically relates to a powder quantitative bagging mechanism. Background Art

[0002] Potassium superoxide, a primary oxidant, can be used as an oxygen generator in fields such as aerospace, submarine technology, and mine first aid. In a closed environment, carbon dioxide and moisture generated during human respiration can react with potassium superoxide to produce oxygen necessary for human survival.

[0003] Since potassium superoxide is a strong oxidant and hygroscopic, the packaging material must be able to effectively isolate moisture and air to prevent it from reacting with the external environment. Usually, a thin film bag is used as the inner packaging, and an open steel drum is used as the outer packaging to ensure the firmness and tightness of the packaging.

[0004] In the existing packaging process, especially in the step of placing the thin film bag inside the metal drum, it mainly relies on manual operation. This step is not only inefficient but also may cause problems such as loose packaging or damage to the thin film bag due to human factors, thus increasing the risk of potassium superoxide coming into contact with the external environment. Summary of the Invention

[0031] A powder quantitative bagging mechanism includes a conveyor belt 6, a bagging mechanism 1, and a quantitative filling mechanism 5. The conveyor belt 6 is used to convey metal barrels as powder storage containers. These metal barrels are placed on the conveyor belt 6 and are conveyed to different workstations for processing as the conveyor belt 6 moves. The bagging mechanism 1 is arranged at the input end of the conveyor belt 6 and is used to release a film bag and place the film bag inside the metal barrel. The quantitative filling mechanism 5 is arranged at the output end of the conveyor belt 6 and is used to fill a preset amount of powder into the film bag inside the metal barrel.

[0032] The bagging mechanism 1 includes a bagging assembly 3, a bag blowing assembly, and a frame. The frame is erected at the input end of the conveyor belt 6. The bagging assembly 3 includes a top plate 19. Both sides of the top of the frame are provided with side support plates 2. The top plate 19 is located between the two groups of side support plates 2 and is slidably connected to the side support plates 2 on both sides through slide rails. A first cylinder 4 is fixedly installed at the top of each side support plate 2. The push rod of the first cylinder 4 is fixed to the upper end surface of the top plate 19 to provide power for the lifting of the top plate 19.

[0033] A first support seat 18 is fixedly mounted on a pair of diagonally opposite corners at the bottom of the top plate 19, and a second support seat 20 is fixedly mounted on another pair of diagonally opposite corners at the bottom of the top plate 19, forming a cross layout with the first support seat 18. A total of four groups of swing arms 22 are hinged on the first support seat 18 and the second support seat 20, respectively, and can swing on their respective support seats. A third cylinder 21 is hinged on one side of the first support seat 18, and the push rod of the third cylinder 21 is hinged with the adjacent swing arm 22. The third cylinder 21 drives the push rod to perform telescopic movement through air pressure, thereby driving the swing arm 22 to swing. A mounting seat 23 is fixed between two adjacent groups of swing arms 22, so that the two adjacent groups of swing arms 22 are connected as a whole to achieve synchronous swinging. One or more suction cups 24 are arranged on the mounting seat 23, and the suction cup 24 adsorbs the film bag by generating negative pressure.

[0034] The bag blowing assembly includes a third support seat 28 fixedly mounted on both sides of the bottom of the top plate 19, and the third support seat 28 is hinged with a spread arm 26 that can swing toward the center of the top plate 19. Among them, a nozzle 27 is installed at the head end of the spread arm 26, and a fourth cylinder 25 is hinged at the end of the spread arm 26, and the other end of the fourth cylinder 25 is hinged to the third support seat 28. The two groups of mounting seats 23 are symmetrically distributed, and the nozzle 27 is located on the symmetric plane of the two groups of mounting seats 23.

[0035] A cutting assembly 10 for cutting film bags and sealing them is arranged above the bagging assembly 3, and the cutting assembly 10 includes a first transverse plate 12 and a second transverse plate 13. The first transverse plate 12 is fixedly installed between the two sets of side support plates 2, and the second transverse plate 13 is slidably connected between the two sets of side support plates 2. The second cylinder 11 is hinged at both ends of the first transverse plate 12, and the push rod of the second cylinder 11 is hinged to the second transverse plate 13. The telescopic movement of the second cylinder 11 drives the second transverse plate 13 away from or close to the first transverse plate 12. A first hot cutting assembly facing the second transverse plate 13 is installed on the first transverse plate 12, and the first hot cutting assembly includes a fixed knife 15 installed on the top of the first transverse plate 12 and a first heating plate 16 installed at the bottom of the first transverse plate 12. A second hot cutting assembly facing the first hot cutting assembly is installed on the second transverse plate 13, and the second hot cutting assembly includes a movable knife 14 installed on the top of the second transverse plate 13 and a second heating plate 17 installed at the bottom of the second transverse plate 13.

[0036] On one side of the frame, there is a unwinding mechanism for storing and orderly releasing tubular film bags. The unwinding mechanism includes a frame body 8 fixed on one side of the frame. At the bottom of the frame body 8, there is an unwinding roller 7, and the film bags are tightly wound around the unwinding roller 7 in a tubular form. Along the conveying route, multiple groups of guiding rollers 9 are arranged inside the frame body 8, and the guiding roller 9 at the conveying end is directly above the cutting assembly 10. The main function of the guiding roller 9 is to guide and support the conveying of the film bags to ensure that the film bags can be smoothly and accurately conveyed into the cutting assembly 10. There is also a pinch roller (not shown in the figure, the pinch roller is a kind of clamping feeding mechanism, and its structure is a mature technology, so no more details will be described here) arranged between the last guiding roller 9 and the cutting assembly 10 to provide additional traction force to ensure that the film bags can be continuously and stably conveyed.

[0037] A first in-place sensor is arranged on the bagging mechanism 1 to detect whether the film bag is in place. Two sets of in-place sensors are installed on the conveyor belt 6: the second in-place sensor is located below the bagging mechanism 1 to detect whether the metal bucket to be bagged has accurately reached the bagging station; the third in-place sensor is located below the quantitative filling mechanism 5 to detect whether the metal bucket that has been bagged with a film bag and is ready for filling has reached the filling station.

[0038] The unwinding roller 7 rotates to release the film bag, and the film bag passes through the gap between the first cross plate 12 and the second cross plate 13 and drops from the hole in the top plate 19. When the first in-place sensor detects the film bag, it sends a signal to the control system. All the third cylinders 21 simultaneously push out the push rods, the two sets of mounting seats 23 approach each other, the suction cups 24 are connected to the negative pressure circuit to adsorb the film bag, and then all the third cylinders 21 simultaneously pull the push rods, the two sets of mounting seats 23 move away from each other, the suction cups 24 maintain negative pressure, and the film bag is stretched open.

[0039] Meanwhile, the metal bucket moves along with the conveyor belt 6 to the lower part of the bagging mechanism 1. When the second in-place sensor detects the metal bucket, the second in-place sensor sends a signal to the control system. All the first cylinders 4 simultaneously push out the push rods to push the top plate 19 closer to the metal bucket, and the stretched film bag drops accordingly, so that a part of the film bag is sleeved on the outside of the metal bucket. After the first cylinder 4 drops to a predetermined height, it stops moving. All the fourth cylinders 25 simultaneously push out the push rods, the two sets of spreading arms 26 approach each other, and the nozzles 27 blow the film bag with a small air flow to make it gather towards the center of the metal bucket. Subsequently, the second cylinder 11 pulls the push rod, and the second cross plate 13 approaches the first cross plate 12 to complete heat sealing and cutting. While the second cylinder 11 is operating, the air flow blown by the nozzles 27 increases, and the film bag is blown into the metal bucket.

[0040] Finally, all the actuating components return to their original positions, the conveyor belt 6 continues to move, and the metal bucket with the film bag sleeved is sent to the quantitative filling mechanism 5 to complete quantitative bagging.

[0041] In accordance with the embodiments of the present invention as described above, these embodiments do not exhaustively describe all the details and do not limit the invention to only the specific embodiments. Obviously, many modifications and variations can be made based on the above description. The present specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and its modified use based on the present invention.
