[0003] Although traditional fully automatic powder feeders can realize automatic feeding of powdered materials, they have some limitations in design and function, especially the problem that the outlet size cannot be adjusted. The outlet size of common fully automatic powder feeders is usually fixed and cannot be adjusted according to actual needs. This leads to the inability to flexibly control the flow and speed of materials during the feeding process, thus affecting production efficiency and product quality. Especially when handling materials of different types or particle sizes, problems such as material blockage, overflow or uneven feeding may occur due to the mismatch of outlet size.

[0004] In addition, the traditional fully automatic powder feeder also has certain deficiencies in the contact mode between the screw and the inner wall of the feeding channel.

[0029] Embodiment 1: A fully automatic powder feeder comprises a front support frame 1, a terminal support frame 2, a motor 3, a feeding channel 4 and an adjusting component, wherein the front support frame 1 and the terminal support frame 2 are respectively arranged at both ends of the feeding channel 4, the motor 3 is located in the top groove of the front support frame 1, a feeding port is arranged at the top of the feeding channel 4 near one end of the motor 3, and an adjusting component is arranged on the outer side of the feeding channel 4 near the terminal support frame 2;

[0030] The adjustment component includes a movable baffle 9 and an adjustment rotary rod 10. Two movable baffles 9 are provided and are arranged outside the feeding channel 4. Two adjustment rotary rods 10 are provided. The adjustment rotary rods 10 are also arranged outside the feeding channel 4 and have threads on the outside. The adjustment rotary rod 10 is threadedly connected to the movable baffle 9.

[0031] In this embodiment, the outside of the feeding channel 4 is a long rectangular parallelepiped with a cylindrical feeding hole inside. Two support plates 5 are welded to the outside of the feeding channel 4. A discharge port is also provided at the bottom of the feeding channel 4 and between the two support plates 5. One support plate 5 is located at the end of the feeding channel 4.

[0032] It should be noted that the feeding channel 4 is designed to be a long rectangular parallelepiped on the outside and a cylindrical feeding hole on the inside. This design is to ensure the smoothness of the feeding process when the material is rotating with the screw rod 11. By welding two support plates 5 on the outside of the feeding channel 4 and opening a discharge port at the bottom thereof, effective control and output of the material are achieved. A support plate 5 is located at the end of the feeding channel 4, which provides a stable foundation for its subsequent connection with the adjustment component.

[0033] In this embodiment, a protective plate 6 is welded to the outer side of the support plate 5 located at the end of the feeding channel 4, a small motor is fixed by internal bolts of the protective plate 6, a small shaft is fixed by bolts at the output end of the small motor, and the end of the small shaft is rotatably connected to the support plate 5 through a bearing, and a driving wheel 7 is fixed by external bolts of the small shaft.

[0034] In this embodiment, two driven wheels 8 are meshed on the outside of the driving wheel 7. The middle of the two driven wheels 8 are respectively fixed with bolts at one end of two adjusting rotary rods 10. The other end of the adjusting rotary rod 10 is rotatably connected to another support plate 5 through a bearing.

[0035] It should be noted that the small motor drives the small shaft and the driving wheel 7 to rotate, thereby further driving the two driven wheels 8 and the adjustment rotating rod 10 connected thereto to rotate. This mechanism not only simplifies the operation process, but also improves the flexibility and response speed of the adjustment.

[0036] In this embodiment, the two adjusting rods 10 are of the same size, and the outside of the adjusting rod 10 is provided with threaded sections in opposite directions and symmetrically distributed, and is threadedly connected to the two movable baffles 9 through the threaded sections. The movable baffle 9 is U-shaped, and its inner wall is provided with a sliding foot 901 and is slidably connected to the outside of the feeding channel 4 through a sliding groove, and threaded grooves 902 are opened inside the two side walls of the movable baffle 9.

[0037] It should be noted that the setting of the movable baffle 9 allows the user to adjust the size of the discharge port by rotating the adjusting rod 10, thereby achieving precise control of the material flow rate. The threaded design of the outer surface of the adjusting rod 10 and the threaded connection with the movable baffle 9 ensure the accuracy and stability of the adjustment.

[0038] Embodiment 2: A screw feeding mechanism, which is applied to a fully automatic powder feeder, further comprising a screw rod 11, the screw rod 11 being composed of a threaded column 1101 and a threaded scraper 1102;

[0039] A threaded fixing groove 1103 is formed on the outside of the threaded column 1101 , and a threaded insert 1104 is disposed on the inside of the threaded scraper 1102 . The threaded insert 1104 is plugged into the threaded fixing groove 1103 and fixed with bolts.

[0040] It should be noted that the screw feeding mechanism realizes the conveying of materials by the rotation of the screw rod 11. The screw rod 11 is composed of a threaded column 1101 and a threaded scraper 1102. This modular design allows the threaded scraper 1102 to be replaced according to different material characteristics. The threaded plug block 1104 on the inner side of the threaded scraper 1102 is plugged into the threaded fixing groove 1103 on the outer side of the threaded column 1101 and then fixed by bolts. This connection method not only facilitates the replacement of the threaded scraper 1102, but also ensures the stable connection between it and the threaded column 1101.

[0041] In this embodiment, one end of the screw rod 11 is fixed to the output end of the motor 3 by bolts, and the other end of the screw rod 11 is rotatably connected to the inner wall of the feeding channel 4 through a bearing.

[0042] Working principle:

[0043] The small motor drives the small shaft and the driving wheel 7 to rotate, thereby driving the driven wheel 8 and the two adjusting rotary rods 10 to rotate. Since the adjusting rotary rods 10 are of the same shape and size and the symmetrically distributed threaded sections arranged on the outside are threadedly connected with the two movable baffles 9, the two movable baffles 9 are close to or away from each other, and the size of the discharge port is controlled while ensuring that the discharge is always carried out in the middle of the discharge port. The setting of the sliding foot 901 and the slide groove makes the movement of the movable baffle 9 directional and more stable. When feeding, the raw materials are first poured into the feed port. As the motor 3 drives the screw rod 11 to rotate, the raw materials are transported to the adjusted discharge port for automatic feeding. At the same time, the screw rod 11 is composed of a threaded column 1101 and a threaded scraper 1102. The threaded scraper 1102 can be replaced according to the raw materials of different materials, which is also conducive to extending the service life of the threaded column 1101.

[0044] Beneficial effects:

[0045] The screw feeding mechanism and the fully automatic powder feeder support the feeding channel 4 through the front support frame 1 and the end support frame 2, and the motor 3 drives the screw rod 11 to rotate to realize feeding. The feeding channel 4 is provided with an adjustment component outside, including two movable baffles 9 and two adjusting rotary rods 10. The driving wheel 7 and the driven wheel 8 are driven to rotate by a small motor, thereby driving the adjusting rotary rod 10 to rotate. Since the symmetrically distributed threaded sections arranged outside the adjusting rotary rod 10 are connected with the thread groove 902 of the movable baffle 9, the two movable baffles 9 are moved closer to or away from each other, thereby adjusting the size of the discharge port. In addition, the screw rod 11 is composed of a threaded column 1101 and a threaded scraper 1102, which is fixed by bolts after the threaded plug block 1104 is plugged into the threaded fixing groove 1103, so that the threaded scraper 1102 is replaced according to the material characteristics, and the direct contact between the threaded column 1101 and the inner wall of the feeding channel 4 is reduced, thereby extending the service life.
