[0020] A powder quantitative bagging mechanism comprises 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 containers. These metal barrels are placed on the conveyor belt 6 and are transported 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 in the metal barrel.

[0021] The bagging mechanism 1 includes a bagging assembly 3, a bag blowing assembly and a frame, and the frame is set at the input end of the conveyor belt 6. The bagging assembly 3 includes a top plate 19, and side support plates 2 are installed on both sides of the top of the frame. The top plate 19 is located between the two sets 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 on the top of each side support plate 2, and 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 and lowering of the top plate 19.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] A reeling mechanism is provided on one side of the frame for storing and releasing tubular film bags in an orderly manner. The reeling mechanism includes a frame body 8 fixed on one side of the frame, and a reeling roller 7 is provided at the bottom of the frame body 8. The film bag is tightly wound around the reeling roller 7 in a tubular form. Along the conveying route, multiple groups of guide rollers 9 are provided inside the frame body 8, and the guide rollers 9 at the conveying end are located directly above the cutting assembly 10. The main function of the guide rollers 9 is to guide and support the conveying of the film bag to ensure that the film bag can be smoothly and accurately conveyed to the cutting assembly 10. A pinch roller (not shown in the figure, the pinch roller is a clamping feeding mechanism, and its structure is a mature technology, so it will not be described in detail here) is also provided between the guide roller 9 at the end and the cutting assembly 10 to provide additional traction to ensure that the film bag can be conveyed continuously and stably.

[0026] The bagging mechanism 1 is provided with a first in-place sensor 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 barrel to be bagged has accurately arrived at the bagging station; the third in-place sensor is located below the quantitative filling mechanism 5 to detect whether the metal barrel that has been bagged and is ready for filling has arrived at the filling station.

[0027] The unwinding roller 7 rotates to release the film bag, and the film bag passes through the gap between the first transverse plate 12 and the second transverse plate 13 and falls from the hole of the top plate 19. When the first in-position sensor detects the film bag, it sends a signal to the control system, and all the third cylinders 21 push the push rods at the same time, the two sets of mounting seats 23 approach each other, and the suction cups 24 connect the negative pressure circuit to absorb the film bag. Then all the third cylinders 21 pull the push rods at the same time, 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.

[0028] At the same time, the metal barrel moves with the conveyor belt 6 to the bottom of the bagging mechanism 1. When the second in-position sensor detects the metal barrel, the second in-position sensor sends a signal to the control system, and all the first cylinders 4 push out the push rods at the same time, pushing the top plate 19 close to the metal barrel, and the stretched film bag drops accordingly, so that part of the film bag is covered on the outside of the metal barrel. The first cylinder 4 stops moving after falling to a predetermined height, and all the fourth cylinders 25 push out the push rods at the same time, and the two groups of arms 26 approach each other. The nozzle 27 blows the film bag with a small airflow to make it gather towards the center of the metal barrel. Subsequently, the second cylinder 11 pulls the push rod, and the second horizontal plate 13 approaches the first horizontal plate 12, completing heat sealing and cutting. While the second cylinder 11 is in motion, the airflow blown out by the nozzle 27 increases, blowing the film bag into the metal barrel.

[0029] Finally, all the execution components are reset, and the conveyor belt 6 continues to move, and the metal barrel covered with the film bag is sent to the quantitative filling mechanism 5 to complete the quantitative bagging.

[0030] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This 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 the modified use based on the present invention.
